Switzerland (German: die Schweiz[note 3] [ˈʃvaɪts]; French: Suisse [sɥis]; Italian: Svizzera [ˈzvittsera]; Romansh: Svizra [ˈʒviːtsrɐ] or [ˈʒviːtsʁːɐ]), officially the Swiss Confederation (Latin: Confoederatio Helvetica, hence its abbreviation CH), is a federal parliamentary republic consisting of 26 cantons, with Bern as the seat of the federal authorities, the so-called Bundesstadt ("federal city").[1] The country is situated in Western and Central Europe,[note 4] where it is bordered by Italy to the south, France to the west, Germany to the north, and Austria and Liechtenstein to the east. Switzerland is a landlocked country geographically divided between the Alps, the Swiss Plateau and the Jura, spanning an area of 41,285 km2 (15,940 sq mi). While the Alps occupy the greater part of the territory, the Swiss population of approximately 8 million people is concentrated mostly on the Plateau, where the largest cities are to be found. Among them are the two global cities and economic centres of Zürich and Geneva.

The establishment of the Swiss Confederation is traditionally dated to 1 August 1291, which is celebrated annually as Swiss National Day. It has a long history of armed neutrality—it has not been in a state of war internationally since 1815—and did not join the United Nations until 2002. It pursues, however, an active foreign policy and is frequently involved in peace-building processes around the world.[9] Switzerland is also the birthplace of the Red Cross and home to numerous international organizations, including the second largest UN office. On the European level, it is a founding member of the European Free Trade Association and is part of the Schengen Area – although it is notably not a member of the European Union, nor the European Economic Area. Switzerland comprises four main linguistic and cultural regions: German, French, Italian and the Romansh-speaking valleys. Therefore, the Swiss, although predominantly German-speaking, do not form a nation in the sense of a common ethnic or linguistic identity; rather, the strong sense of identity and community is founded on a common historical background, shared values such as federalism and direct democracy,[10] and Alpine symbolism.[11]

Switzerland has the highest nominal wealth per adult (financial and non-financial assets) in the world according to Credit Suisse and eighth-highest per capita gross domestic product on the IMF list.[12][13] However, Switzerland is also the most expensive country in the world to live in, as measured by the price level index.[14]

Swiss citizens have the second-highest life expectancy in the world on the UN DESA list. Switzerland is tied with the Netherlands for the top rank on the Bribe Payers Index indicating very low levels of business corruption. Moreover, for the last five years the country has been ranked first in economic and tourist competitiveness according to the Global Competitiveness Report and the Travel and Tourism Competitiveness Report respectively, both developed by the World Economic Forum. Zürich and Geneva have each been ranked among the top cities with the highest quality of life in the world, with the former coming second globally according to Mercer.[15] However, Mercer also rates those two cities as the fifth- and sixth- most expensive cities in the world to live in.[16]

Etymology

The English name Switzerland is a compound containing Switzer, an obsolete term for the Swiss, which was in use during the 16th to 19th centuries.[17] The English adjective Swiss is a loan from French Suisse, also in use since the 16th century. The name Switzer is from the Alemannic Schwiizer, in origin an inhabitant of Schwyz and its associated territory, one of the Waldstätten cantons which formed the nucleus of the Old Swiss Confederacy. The name originates as an exonym, applied pars pro toto to the troops of the Confederacy. The Swiss themselves began to adopt the name for themselves after the Swabian War of 1499, used alongside the term for "Confederates", Eidgenossen (literally: comrades by oath), used since the 14th century. The toponym Schwyz itself is first attested in 972, as Old High German Suittes, ultimately perhaps related to suedan "to burn", referring to the area of forest that was burned and cleared to build.[18] The name was extended to the area dominated by the canton, and after the Swabian War of 1499 gradually came to be used for the entire Confederation.[19][20] The Swiss German name of the country, Schwiiz, is homophonous to that of the canton and the settlement, but distinguished by the use of the definite article (d'Schwiiz for the Confederation,[21] but simply Schwyz for the canton and the town).[22]

The Latin name Confoederatio Helvetica was neologized and introduced gradually after the formation of the federal state in 1848, harking back to the Napoleonic Helvetic Republic, appearing on coins from 1879, inscribed on the Federal Palace in 1902 and after 1948 used in the official seal.[23] It is derived from the name of the Helvetii, a Gaulish tribe living on the Swiss plateau before the Roman era. Helvetia appears as a national personification of the Swiss confederacy in the 17th century, with a 1672 play by Johann Caspar Weissenbach.[24]

History

Switzerland has existed as a state in its present form since the adoption of the Swiss Federal Constitution in 1848. The precursors of Switzerland established a protective alliance at the end of the 13th century (1291), forming a loose confederation of states which persisted for centuries.

Early history

The oldest traces of hominid existence in Switzerland date back about 150,000 years.[25] The oldest known farming settlements in Switzerland, which were found at Gächlingen, have been dated to around 5300 BC.[25]
Founded in 44 BC by Lucius Munatius Plancus, Augusta Raurica was the first Roman settlement on the Rhine and is now among the most important archaeological sites in Switzerland.[26]

The earliest known cultural tribes of the area were members of the Hallstatt and La Tène cultures, named after the archaeological site of La Tène on the north side of Lake Neuchâtel. La Tène culture developed and flourished during the late Iron Age from around 450 BC,[25] possibly under some influence from the Greek and Etruscan civilisations. One of the most important tribal groups in the Swiss region was the Helvetii. Steadily harassed by the Germans, in 58 BC the Helvetii decided to abandon the Swiss plateau and migrate to western Gallia, but Julius Caesar's armies pursued and defeated them at the Battle of Bibracte, in today's western France, forcing the tribe to move back to its original homeland.[25] In 15 BC, Tiberius, who was destined to be the second Roman emperor and his brother, Drusus, conquered the Alps, integrating them into the Roman Empire. The area occupied by the Helvetii—the namesakes of the later Confoederatio Helvetica—first became part of Rome's Gallia Belgica province and then of its Germania Superior province, while the eastern portion of modern Switzerland was integrated into the Roman province of Raetia. Sometime around the start of the Common Era, the Romans maintained a large legionary camp called Vindonissa, now a ruin at the confluence of the Aare and Reuss rivers, near the town of Windisch, an outskirt of Brugg.

The first and second century AD were an age of prosperity for the population living along the Swiss plateau. Several towns, like Aventicum, Iulia Equestris and Augusta Raurica, reached a remarkable size, while hundreds of agricultural estates (Villae rusticae) were founded in the countryside.

About in 260 AD, the fall of the Agri Decumates territory north of Rhine transformed today's Switzerland in a frontier land of the Empire. Repeated raids of the Alamanni tribe provoked the ruin of the Roman towns and economy, forcing the population to find shelter near Roman fortresses, like the Castrum Rauracense near Augusta Raurica. The Empire built another line of defense at the north border (the so-called Donau-Iller-Rhine-Limes), but at the end of the fourth century the increased Germanic pressure forced the Romans to abandon the linear defence concept, and the Swiss plateau was finally open to the settlement of German tribes.

In the Early Middle Ages, from the 4th century, the western extent of modern-day Switzerland was part of the territory of the Kings of the Burgundians. The Alemanni settled the Swiss plateau in the 5th century and the valleys of the Alps in the 8th century, forming Alemannia. Modern-day Switzerland was therefore then divided between the kingdoms of Alemannia and Burgundy.[25] The entire region became part of the expanding Frankish Empire in the 6th century, following Clovis I's victory over the Alemanni at Tolbiac in 504 AD, and later Frankish domination of the Burgundians.[27][28]

Throughout the rest of the 6th, 7th and 8th centuries the Swiss regions continued under Frankish hegemony (Merovingian and Carolingian dynasties). But after its extension under Charlemagne, the Frankish empire was divided by the Treaty of Verdun in 843.[25] The territories of present day Switzerland became divided into Middle Francia and East Francia until they were reunified under the Holy Roman Empire around 1000 AD.[25]

By 1200, the Swiss plateau comprised the dominions of the houses of Savoy, Zähringer, Habsburg, and Kyburg.[25] Some regions (Uri, Schwyz, Unterwalden, later known as Waldstätten) were accorded the Imperial immediacy to grant the empire direct control over the mountain passes. With the extinction of its male line in 1263 the Kyburg dynasty fell in AD 1264; then the Habsburgs under King Rudolph I (Holy Roman Emperor in 1273) laid claim to the Kyburg lands and annexed them extending their territory to the eastern Swiss plateau.[27]

Old Swiss Confederacy

The 1291 Bundesbrief (Federal charter)

The Old Swiss Confederacy was an alliance among the valley communities of the central Alps. The Confederacy facilitated management of common interests and ensured peace on the important mountain trade routes. The Federal Charter of 1291 agreed between the rural communes of Uri, Schwyz, and Unterwalden is considered the confederacy's founding document, even though similar alliances are likely to have existed decades earlier.[29][30]

By 1353, the three original cantons had joined with the cantons of Glarus and Zug and the Lucerne, Zürich and Bern city states to form the "Old Confederacy" of eight states that existed until the end of the 15th century. The expansion led to increased power and wealth for the federation.[30] By 1460, the confederates controlled most of the territory south and west of the Rhine to the Alps and the Jura mountains, particularly after victories against the Habsburgs (Battle of Sempach, Battle of Näfels), over Charles the Bold of Burgundy during the 1470s, and the success of the Swiss mercenaries. The Swiss victory in the Swabian War against the Swabian League of Emperor Maximilian I in 1499 amounted to de facto independence within the Holy Roman Empire.[30]

The Old Swiss Confederacy had acquired a reputation of invincibility during these earlier wars, but expansion of the federation suffered a setback in 1515 with the Swiss defeat in the Battle of Marignano. This ended the so-called "heroic" epoch of Swiss history.[30] The success of Zwingli's Reformation in some cantons led to inter-cantonal religious conflicts in 1529 and 1531 (Wars of Kappel). It was not until more than one hundred years after these internal wars that, in 1648, under the Peace of Westphalia, European countries recognized Switzerland's independence from the Holy Roman Empire and its neutrality.[27][28]

During the Early Modern period of Swiss history, the growing authoritarianism of the patriciate families combined with a financial crisis in the wake of the Thirty Years' War led to the Swiss peasant war of 1653. In the background to this struggle, the conflict between Catholic and Protestant cantons persisted, erupting in further violence at the Battles of Villmergen in 1656 and 1712.[30]

Napoleonic era

The Act of Mediation was Napoleon's attempt at a compromise between the Ancien Régime and a Republic.

In 1798, the revolutionary French government conquered Switzerland and imposed a new unified constitution.[30] This centralised the government of the country, effectively abolishing the cantons: moreover, Mülhausen joined France and Valtellina valley, the Cisalpine Republic, separating from Switzerland. The new regime, known as the Helvetic Republic, was highly unpopular. It had been imposed by a foreign invading army and destroyed centuries of tradition, making Switzerland nothing more than a French satellite state. The fierce French suppression of the Nidwalden Revolt in September 1798 was an example of the oppressive presence of the French Army and the local population's resistance to the occupation.

When war broke out between France and its rivals, Russian and Austrian forces invaded Switzerland. The Swiss refused to fight alongside the French in the name of the Helvetic Republic. In 1803 Napoleon organised a meeting of the leading Swiss politicians from both sides in Paris. The result was the Act of Mediation which largely restored Swiss autonomy and introduced a Confederation of 19 cantons.[30] Henceforth, much of Swiss politics would concern balancing the cantons' tradition of self-rule with the need for a central government.

In 1815 the Congress of Vienna fully re-established Swiss independence and the European powers agreed to permanently recognise Swiss neutrality.[27][28][30] Swiss troops still served foreign governments until 1860 when they fought in the Siege of Gaeta. The treaty also allowed Switzerland to increase its territory, with the admission of the cantons of Valais, Neuchâtel and Geneva. Switzerland's borders have not changed since, except some minor adjustments.[31]

Federal state

The first Federal Palace in Bern (1857). One of the three cantons presiding over the Tagsatzung (former legislative and executive council), Bern was chosen as the federal capital in 1848, mainly because of its closeness to the French-speaking area.[32]

The restoration of the power to the patriciate was only temporary. After a period of unrest with repeated violent clashes such as the Züriputsch of 1839, civil war (the Sonderbundskrieg) broke out in 1847 when some Catholic cantons tried to set up a separate alliance (the Sonderbund).[30] The war lasted for less than a month, causing fewer than 100 casualties, most of which were through friendly fire. However minor the Sonderbundskrieg seems to be when compared with other European riots and wars in the 19th century, it nevertheless had a major impact on both the psychology and the society of the Swiss and of Switzerland.

The war convinced most Swiss of the need for unity and strength towards its European neighbours. Swiss people from all strata of society, whether Catholic or Protestant, from the liberal or conservative current, realised that the cantons would profit more if their economic and religious interests were merged.

Thus, while the rest of Europe saw revolutionary uprisings, the Swiss drew up a constitution which provided for a federal layout, much of it inspired by the American example. This constitution provided for a central authority while leaving the cantons the right to self-government on local issues. Giving credit to those who favoured the power of the cantons (the Sonderbund Kantone), the national assembly was divided between an upper house (the Swiss Council of States, 2 representatives per canton) and a lower house (the National Council of Switzerland, representatives elected from across the country). Referenda were made mandatory for any amendment of this constitution.[28]

A system of single weights and measures was introduced and in 1850 the Swiss franc became the Swiss single currency. Article 11 of the constitution forbade sending troops to serve abroad, though the Swiss were still obliged to serve Francis II of the Two Sicilies with Swiss Guards present at the Siege of Gaeta in 1860, marking the end of foreign service.

An important clause of the constitution was that it could be re-written completely if this was deemed necessary, thus enabling it to evolve as a whole rather than being modified one amendment at a time.[34]

This need soon proved itself when the rise in population and the Industrial Revolution that followed led to calls to modify the constitution accordingly. An early draft was rejected by the population in 1872 but modifications led to its acceptance in 1874.[30] It introduced the facultative referendum for laws at the federal level. It also established federal responsibility for defense, trade, and legal matters.
In 1891, the constitution was revised with unusually strong elements of direct democracy, which remain unique even today.[30]

Modern history

General Ulrich Wille, Commander-in-Chief of the Swiss Army during World War I

Switzerland was not invaded during either of the world wars. During World War I, Switzerland was home to Vladimir Illych Ulyanov (Vladimir Lenin) and he remained there until 1917.[35] Swiss neutrality was seriously questioned by the Grimm–Hoffmann Affair in 1917, but it was short-lived. In 1920, Switzerland joined the League of Nations, which was based in Geneva, on the condition that it was exempt from any military requirements.

During World War II, detailed invasion plans were drawn up by the Germans,[36] but Switzerland was never attacked.[30] Switzerland was able to remain independent through a combination of military deterrence, concessions to Germany, and good fortune as larger events during the war delayed an invasion.[28][37] Under General Henri Guisan central command, a general mobilisation of the armed forces was ordered. The Swiss military strategy was changed from one of static defence at the borders to protect the economic heartland, to one of organised long-term attrition and withdrawal to strong, well-stockpiled positions high in the Alps known as the Reduit. Switzerland was an important base for espionage by both sides in the conflict and often mediated communications between the Axis and Allied powers.[37]

Switzerland's trade was blockaded by both the Allies and by the Axis. Economic cooperation and extension of credit to the Third Reich varied according to the perceived likelihood of invasion and the availability of other trading partners. Concessions reached a peak after a crucial rail link through Vichy France was severed in 1942, leaving Switzerland completely surrounded by the Axis. Over the course of the war, Switzerland interned over 300,000 refugees[38] and the International Red Cross, based in Geneva, played an important part during the conflict. Strict immigration and asylum policies as well as the financial relationships with Nazi Germany raised controversy, but not until the end of the 20th century.[39]

During the war, the Swiss Air Force engaged aircraft of both sides, shooting down 11 intruding Luftwaffe planes in May and June 1940, then forcing down other intruders after a change of policy following threats from Germany. Over 100 Allied bombers and their crews were interned during the war. During 1944–45, Allied bombers mistakenly bombed a few places in Switzerland, among which were the cities of Schaffhausen, Basel and Zürich.[37]

After the war, the Swiss government exported credits through the charitable fund known as the Schweizerspende and also donated to the Marshall Plan to help Europe's recovery, efforts that ultimately benefited the Swiss economy.[40]

During the Cold War, Swiss authorities considered the construction of a Swiss nuclear bomb.[41] Leading nuclear physicists at the Federal Institute of Technology Zurich such as Paul Scherrer made this a realistic possibility. However, financial problems with the defense budget prevented the substantial funds from being allocated, and the Nuclear Non-Proliferation Treaty of 1968 was seen as a valid alternative. All remaining plans for building nuclear weapons were dropped by 1988.[42]

Women were granted the right to vote in the first Swiss cantons in 1959, at the federal level in 1971[30][43] and, after resistance, in the last canton Appenzell Innerrhoden (one of only two remaining Landsgemeinde) in 1990. After suffrage at the federal level, women quickly rose in political significance, with the first woman on the seven member Federal Council executive being Elisabeth Kopp, who served from 1984–1989,[30] and the first female president being Ruth Dreifuss in 1999.
In 2003, by granting the Swiss People's Party a second seat in the governing cabinet, the Parliament altered the coalition which had dominated Swiss politics since 1959.

Switzerland joined the Council of Europe in 1963.[28] In 1979 areas from the canton of Bern attained independence from the Bernese, forming the new canton of Jura. On 18 April 1999 the Swiss population and the cantons voted in favour of a completely revised federal constitution.[30]

In 2002 Switzerland became a full member of the United Nations, leaving the Vatican City as the last widely recognised state without full UN membership. Switzerland is a founding member of the EFTA, but is not a member of the European Economic Area. An application for membership in the European Union was sent in May 1992, but not advanced since the EEA was rejected in December 1992[30] when Switzerland was the only country to launch a referendum on the EEA. There have since been several referenda on the EU issue; due to a mixed reaction from the population the membership application has been frozen. Nonetheless, Swiss law is gradually being adjusted to conform with that of the EU, and the government has signed a number of bilateral agreements with the European Union. Switzerland, together with Liechtenstein, has been completely surrounded by the EU since Austria's membership in 1995. On 5 June 2005, Swiss voters agreed by a 55% majority to join the Schengen treaty, a result that was regarded by EU commentators as a sign of support by Switzerland, a country that is traditionally perceived as independent and reluctant to enter supranational bodies.[28]

Geography

Physical map of Switzerland

Extending across the north and south side of the Alps in west-central Europe, Switzerland encompasses a great diversity of landscapes and climates on a limited area of 41,285 square kilometres (15,940 sq mi).[44] The population is about 7.9 million, resulting in an average population density of around 190 people per square kilometre (485/sq mi).[44][45][46] The more mountainous southern half of the country is far more sparsely populated than the northern half.[44] In the largest Canton of Graubünden, lying entirely in the Alps, population density falls to 27 /km² (70 /sq mi).[47]

Switzerland lies between latitudes 45° and 48° N, and longitudes and 11° E. It contains three basic topographical areas: the Swiss Alps to the south, the Swiss plateau or middleland, and the Jura mountains on the north. The Alps are a high mountain range running across the central-south of the country, comprising about 60% of the country's total area. Among the high valleys of the Swiss Alps many glaciers are found, totalling an area of 1,063 square kilometres. From these originate the headwaters of several major rivers, such as the Rhine, Inn, Ticino and Rhône, which flow in the four cardinal directions into the whole of Europe. The hydrographic network includes several of the largest bodies of freshwater in Central and Western Europe, among which are included Lake Geneva, Lake Constance and Lake Maggiore. Switzerland has more than 1500 lakes, and contains 6% of Europe's stock of fresh water. Lakes and glaciers cover about 6% of the national territory.[44][48][49]
Contrasted landscapes between the regions of the Matterhorn and Lake Lucerne

About a hundred of Switzerland's mountain peaks are close to or higher than 4,000 metres (13,000 ft).[50] At 4,634 m (15,203 ft), Monte Rosa is the highest, although the Matterhorn (4,478 m or 14,692 ft) is probably the most famous. Both are located within the Pennine Alps in the canton of Valais. The section of the Bernese Alps above the deep glacial Lauterbrunnen valley, containing 72 waterfalls, is well known for the Jungfrau (4,158 m or 13,642 ft) and Eiger, and the many picturesque valleys in the region. In the southeast the long Engadin Valley, encompassing the St. Moritz area in canton Graubünden, is also well known; the highest peak in the neighbouring Bernina Alps is Piz Bernina (4,049 m or 13,284 ft).[51]

The more populous northern part of the country, comprising about 30% of the country's total area, is called the Middle Land. It has greater open and hilly landscapes, partly forested, partly open pastures, usually with grazing herds, or vegetables and fruit fields, but it is still hilly. There are large lakes found here and the biggest Swiss cities are in this area of the country.[51] The largest lake is Lake Geneva (also called Lac Léman in French), in western Switzerland. The Rhône River is both the main input and output of Lake Geneva.

Climate

The Swiss climate is generally temperate, but can vary greatly between the localities,[52][53] from glacial conditions on the mountaintops to the often pleasant near Mediterranean climate at Switzerland's southern tip. There are some valley areas in the southern part of Switzerland where some cold-hardy palm trees are found. Summers tend to be warm and humid at times with periodic rainfall so they are ideal for pastures and grazing. The less humid winters in the mountains may see long intervals of stable conditions for weeks, while the lower lands tend to suffer from inversion, during these periods, thus seeing no sun for weeks.

A weather phenomenon known as the föhn (with an identical effect to the chinook wind) can occur at all times of the year and is characterised by an unexpectedly warm wind, bringing air of very low relative humidity to the north of the Alps during rainfall periods on the southern face of the Alps. This works both ways across the alps but is more efficient if blowing from the south due to the steeper step for oncoming wind from the south. Valleys running south to north trigger the best effect. The driest conditions persist in all inner alpine valleys that receive less rain because arriving clouds lose a lot of their content while crossing the mountains before reaching these areas. Large alpine areas such as Graubünden remain drier than pre-alpine areas and as in the main valley of the Valais wine grapes are grown there.[54]

The wettest conditions persist in the high Alps and in the Ticino canton which has much sun yet heavy bursts of rain from time to time.[54] Precipitation tends to be spread moderately throughout the year with a peak in summer. Autumn is the driest season, winter receives less precipitation than summer, yet the weather patterns in Switzerland are not in a stable climate system and can be variable from year to year with no strict and predictable periods.

Environment

Switzerland's ecosystems can be particularly fragile, because the many delicate valleys separated by high mountains often form unique ecologies. The mountainous regions themselves are also vulnerable, with a rich range of plants not found at other altitudes, and experience some pressure from visitors and grazing. The climatic, geological and topographical conditions of the alpine region make for a very fragile ecosystem that is particularly sensitive to climate change.[56][57] Nevertheless, according to the 2012 Environmental Performance Index, Switzerland is the first among 132 nations in safeguarding the environment, due to its high scores on environmental public health, its heavy reliance on renewable sources of energy (hydropower and geothermal energy), and its control of greenhouse gas emissions.[58]

Politics

The Swiss Federal Council in 2014 with President Didier Burkhalter (in the middle)[note 5]

The Federal Constitution adopted in 1848 is the legal foundation of the modern federal state. It is among the oldest constitutions in the world.[59] A new Constitution was adopted in 1999, but did not introduce notable changes to the federal structure. It outlines basic and political rights of individuals and citizen participation in public affairs, divides the powers between the Confederation and the cantons and defines federal jurisdiction and authority. There are three main governing bodies on the federal level:[60] the bicameral parliament (legislative), the Federal Council (executive) and the Federal Court (judicial).

The Swiss Parliament consists of two houses: the Council of States which has 46 representatives (two from each canton and one from each half-canton) who are elected under a system determined by each canton, and the National Council, which consists of 200 members who are elected under a system of proportional representation, depending on the population of each canton. Members of both houses serve for 4 years. When both houses are in joint session, they are known collectively as the Federal Assembly. Through referendums, citizens may challenge any law passed by parliament and through initiatives, introduce amendments to the federal constitution, thus making Switzerland a direct democracy.[59]

The Federal Council constitutes the federal government, directs the federal administration and serves as collective Head of State. It is a collegial body of seven members, elected for a four-year mandate by the Federal Assembly which also exercises oversight over the Council. The President of the Confederation is elected by the Assembly from among the seven members, traditionally in rotation and for a one-year term; the President chairs the government and assumes representative functions. However, the president is a primus inter pares with no additional powers, and remains the head of a department within the administration.[59]

The Swiss government has been a coalition of the four major political parties since 1959, each party having a number of seats that roughly reflects its share of electorate and representation in the federal parliament. The classic distribution of 2 CVP/PDC, 2 SPS/PSS, 2 FDP/PRD and 1 SVP/UDC as it stood from 1959 to 2003 was known as the "magic formula". Following the 2011 Federal Council elections, the seven seats in the Federal Council were distributed as follows:
1 seat for the Christian Democratic People's Party (CVP/PDC),
1 seat for the Conservative Democratic Party (BDP/PBD),
2 seats for the Free Democratic Party (FDP/PRD),
2 seats for the Social Democratic Party (SPS/PSS),
1 seat for the Swiss People's Party (SVP/UDC).
The function of the Federal Supreme Court is to hear appeals against rulings of cantonal or federal courts. The judges are elected by the Federal Assembly for six-year terms.[61]

Direct democracy

The Landsgemeinde is an old form of direct democracy. It is still practised in two cantons.[62]

Swiss citizens are subject to three legal jurisdictions: the commune, canton and federal levels. The 1848 federal constitution defines a system of direct democracy (sometimes called half-direct or representative direct democracy because it is aided by the more commonplace institutions of a representative democracy). The instruments of this system at the federal level, known as civic rights (Volksrechte, droits civiques), include the right to submit a constitutional initiative and a referendum, both of which may overturn parliamentary decisions.[59][63]

By calling a federal referendum, a group of citizens may challenge a law passed by Parliament, if they gather 50,000 signatures against the law within 100 days. If so, a national vote is scheduled where voters decide by a simple majority whether to accept or reject the law. Any 8 cantons together can also call a referendum on a federal law.[59]

Similarly, the federal constitutional initiative allows citizens to put a constitutional amendment to a national vote, if 100,000 voters sign the proposed amendment within 18 months.[note 6] Parliament can supplement the proposed amendment with a counter-proposal, and then voters must indicate a preference on the ballot in case both proposals are accepted. Constitutional amendments, whether introduced by initiative or in Parliament, must be accepted by a double majority of the national popular vote and the cantonal popular votes.[note 7][64][65]

Administrative divisions

The Swiss Confederation consists of 26 cantons:[59]

*These cantons are represented by one councillor (instead of two) in the Council of States.

The cantons have a permanent constitutional status and, in comparison with the situation in other countries, a high degree of independence. Under the Federal Constitution, all 26 cantons are equal in status. Each canton has its own constitution, and its own parliament, government and courts.[62] However, there are considerable differences between the individual cantons, most particularly in terms of population and geographical area. Their populations vary between 15,000 (Appenzell Innerrhoden) and 1,253,500 (Zürich), and their area between 37 km2 (14 sq mi) (Basel-Stadt) and 7,105 km2 (2,743 sq mi) (Graubünden). The Cantons comprise a total of 2,485 municipalities. Within Switzerland there are two enclaves: Büsingen belongs to Germany, Campione d'Italia belongs to Italy.[66]

In a referendum held in the Austrian state of Vorarlberg on 11 May 1919, over 80% of those voting supported a proposal that the state should join the Swiss Confederation. However, this was prevented by the opposition of the Austrian Government, the Allies, Swiss liberals and non-German-speaking Swiss.[67][68]

Foreign relations and international institutions

Traditionally, Switzerland avoids alliances that might entail military, political, or direct economic action and had been neutral since the end of its expansion in 1515. Its policy of neutrality was internationally recognised at the Congress of Vienna in 1815.[69][70] Only in 2002 did Switzerland become a full member of the United Nations[69] and it was the first state to join it by referendum.
Switzerland maintains diplomatic relations with almost all countries and historically has served as an intermediary between other states.[69] Switzerland is not a member of the European Union; the Swiss people have consistently rejected membership since the early 1990s.[69]
The monochromatically reversed Swiss flag became the symbol of the Red Cross Movement,[43] founded in 1863 by Henri Dunant.[71]

An unusual number of international institutions have their seats in Switzerland, in part because of its policy of neutrality. Geneva is the birthplace of the Red Cross and Red Crescent Movement and the Geneva Conventions and, since 2006, hosts the United Nations Human Rights Council. Even though Switzerland is one of the most recent countries to have joined the United Nations, the Palace of Nations in Geneva is the second biggest centre for the United Nations after New York, and Switzerland was a founding member and home to the League of Nations.

Apart from the United Nations headquarters, the Swiss Confederation is host to many UN agencies, like the World Health Organization (WHO), the International Labour Organization (ILO), the International Telecommunication Union (ITU), the United Nations High Commissioner for Refugees (UNHCR) and about 200 other international organisations, including the World Trade Organization.[69] The annual meetings of the World Economic Forum in Davos bring together top international business and political leaders from Switzerland and foreign countries to discuss important issues facing the world, including health and the environment.

Furthermore, many sport federations and organisations are located throughout the country, such as the International Basketball Federation in Geneva, the Union of European Football Associations (UEFA) in Nyon, the International Federation of Association Football (FIFA) and the International Ice Hockey Federation both in Zürich, the International Cycling Union in Aigle, and the International Olympic Committee in Lausanne.[72]

Military

The Swiss Armed Forces, including the Land Forces and the Air Force, are composed mostly of conscripts, male citizens aged from 20 to 34 (in special cases up to 50) years. Being a landlocked country, Switzerland has no navy; however, on lakes bordering neighbouring countries, armed military patrol boats are used. Swiss citizens are prohibited from serving in foreign armies, except for the Swiss Guards of the Vatican, or if they are dual citizens of a foreign country and reside there.

The structure of the Swiss militia system stipulates that the soldiers keep their Army issued equipment, including all personal weapons, at home. Some organizations and political parties find this practice controversial[73] but mainstream Swiss opinion is in favour of the system. Compulsory military service concerns all male Swiss citizens; women can serve voluntarily. Men usually receive military conscription orders for training at the age of 18.[74] About two thirds of the young Swiss are found suited for service; for those found unsuited, various forms of alternative service exist.[75] Annually, approximately 20,000 persons are trained in recruit centres for a duration from 18 to 21 weeks. The reform "Army XXI" was adopted by popular vote in 2003, it replaced the previous model "Army 95", reducing the effectives from 400,000 to about 200,000. Of those, 120,000 are active in periodic Army training and 80,000 are non-training reserves.[76]

Overall, three general mobilisations have been declared to ensure the integrity and neutrality of Switzerland. The first one was held on the occasion of the Franco-Prussian War of 1870–71. The second one was decided in response to the outbreak of the First World War in August 1914. The third mobilisation of the army took place in September 1939 in response to the German attack on Poland; Henri Guisan was elected as the General-in-Chief.

Because of its neutrality policy, the Swiss army does not currently take part in armed conflicts in other countries, but is part of some peacekeeping missions around the world. Since 2000 the armed force department has also maintained the Onyx intelligence gathering system to monitor satellite communications.[77]

Following the end of the Cold War there have been a number of attempts to curb military activity or even abolish the armed forces altogether. A notable referendum on the subject, launched by an anti-militarist group, was held on 26 November 1989. It was defeated with about two thirds of the voters against the proposal.[78][79] A similar referendum, called for before, but held shortly after, the 11 September attacks in the US, was defeated by over 78% of voters.[80]

Economy and laboral law

Switzerland has a stable, prosperous and high-tech economy and enjoys great wealth, being ranked as the wealthiest country in the world in per capita in multiple rankings. In 2011 it was ranked as the wealthiest country in the world in per capita terms (with "wealth" being defined to include both financial and non-financial assets), while the 2013 Credit Suisse Global Wealth Report showed that Switzerland was the country with the highest average wealth per adult in 2013.[82][83][84] It has the world's nineteenth largest economy by nominal GDP and the thirty-sixth largest by purchasing power parity. It is the twentieth largest exporter, despite its size. Switzerland has the highest European rating in the Index of Economic Freedom 2010, while also providing large coverage through public services.[85] The nominal per capita GDP is higher than those of the larger Western and Central European economies and Japan.[86] If adjusted for purchasing power parity, Switzerland ranks 8th in the world in terms of GDP per capita, according to the World Bank and IMF (ranked 15th according to the CIA Worldfactbook[86]).

The World Economic Forum's Global Competitiveness Report currently ranks Switzerland's economy as the most competitive in the world,[87] while ranked by the European Union as Europe's most innovative country.[88] For much of the 20th century, Switzerland was the wealthiest country in Europe by a considerable margin (by GDP – per capita).[89] In 2007 the gross median household income in Switzerland was an estimated 137,094 USD at Purchasing power parity while the median income was 95,824 USD.[90] Switzerland also has one of the world's largest account balances as a percentage of GDP.
The Greater Zürich Area, home to 1.5 million inhabitants and 150,000 companies, is one of the most important economic centres in the world.[91]

Switzerland is home to several large multinational corporations. The largest Swiss companies by revenue are Glencore, Gunvor, Nestlé, Novartis, Hoffmann-La Roche, ABB, Mercuria Energy Group and Adecco.[92] Also, notable are UBS AG, Zurich Financial Services, Credit Suisse, Barry Callebaut, Swiss Re, Tetra Pak, The Swatch Group and Swiss International Airlines. Switzerland is ranked as having one of the most powerful economies in the world.[89]

Switzerland's most important economic sector is manufacturing. Manufacturing consists largely of the production of specialist chemicals, health and pharmaceutical goods, scientific and precision measuring instruments and musical instruments. The largest exported goods are chemicals (34% of exported goods), machines/electronics (20.9%), and precision instruments/watches (16.9%).[93] Exported services amount to a third of exports.[93] The service sector – especially banking and insurance, tourism, and international organisations – is another important industry for Switzerland.

Around 3.8 million people work in Switzerland; about 25% of employees belonged to a trade union in 2004.[94] Switzerland has a more flexible job market than neighbouring countries and the unemployment rate is very low. The unemployment rate increased from a low of 1.7% in June 2000 to a peak of 4.4% in December 2009.[95] Population growth from net immigration is quite high, at 0.52% of population in 2004.[93] The foreign citizen population was 21.8% in 2004,[93] about the same as in Australia. GDP per hour worked is the world's 16th highest, at 49.46 international dollars in 2012.[96]

Switzerland has an overwhelmingly private sector economy and low tax rates by Western World standards; overall taxation is one of the smallest of developed countries. Switzerland is a relatively easy place to do business, currently ranking 28th of 178 countries in the Ease of Doing Business Index. The slow growth Switzerland experienced in the 1990s and the early 2000s has brought greater support for economic reforms and harmonization with the European Union.[97][98] According to Credit Suisse, only about 37% of residents own their own homes, one of the lowest rates of home ownership in Europe. Housing and food price levels were 171% and 145% of the EU-25 index in 2007, compared to 113% and 104% in Germany.[93]

The Swiss Federal budget had a size of 62.8 billion Swiss francs in 2010, which is an equivalent 11.35% of the country's GDP in that year; however, the regional (canton) budgets and the budgets of the municipalities are not counted as part of the federal budget and the total rate of government spending is closer to 33.8% of GDP. The main sources of income for the federal government are the value-added tax (33%) and the direct federal tax (29%) and the main expenditure is located in the areas of social welfare and finance & tax. The expenditures of the Swiss Confederation have been growing from 7% of GDP in 1960 to 9.7% in 1990 and to 10.7% in 2010. While the sectors social welfare and finance & tax have been growing from 35% in 1990 to 48.2% in 2010, a significant reduction of expenditures has been occurring in the sectors of agriculture and national defense; from 26.5% in to 12.4% (estimation for the year 2015).[99][100]

Agricultural protectionism—a rare exception to Switzerland's free trade policies—has contributed to high food prices. Product market liberalisation is lagging behind many EU countries according to the OECD.[97] Nevertheless, domestic purchasing power is one of the best in the world.[101][102][103] Apart from agriculture, economic and trade barriers between the European Union and Switzerland are minimal and Switzerland has free trade agreements worldwide. Switzerland is a member of the European Free Trade Association (EFTA).

Switzerland has the world's nineteenth largest economy by nominal GDP and the thirty-sixth largest by purchasing power parity. Switzerland is the fifteenth largest exporter and seventeenth largest importer of goods.

Education and science

Some Swiss scientists who played a key role in their discipline (clockwise):
Leonhard Euler (mathematics)
Louis Agassiz (glaciology)
Auguste Piccard (aeronautics)
Albert Einstein (physics)

Education in Switzerland is very diverse because the constitution of Switzerland delegates the authority for the school system to the cantons.[104] There are both public and private schools, including many private international schools. The minimum age for primary school is about six years in all cantons, but most cantons provide a free "children's school" starting at four or five years old.[104] Primary school continues until grade four, five or six, depending on the school. Traditionally, the first foreign language in school was always one of the other national languages, although recently (2000) English was introduced first in a few cantons.[104]

At the end of primary school (or at the beginning of secondary school), pupils are separated according to their capacities in several (often three) sections. The fastest learners are taught advanced classes to be prepared for further studies and the matura,[104] while students who assimilate a little more slowly receive an education more adapted to their needs.
The campus of the ETH Zurich. The institution is usually ranked the top university in continental Europe.[105][106]

There are 12 universities in Switzerland, ten of which are maintained at cantonal level and usually offer a range of non-technical subjects. The first university in Switzerland was founded in 1460 in Basel (with a faculty of medicine) and has a tradition of chemical and medical research in Switzerland. The biggest university in Switzerland is the University of Zurich with nearly 25,000 students. The two institutes sponsored by the federal government are the ETHZ in Zürich (founded 1855) and the EPFL in Lausanne (founded 1969 as such, formerly an institute associated with the University of Lausanne) which both have an excellent international reputation.[note 8][107]

In addition, there are various Universities of Applied Sciences. In business and management studies, University of St. Gallen, (HSG) and International Institute for Management Development (IMD) are the leaders within the country and highly regarded internationally. Switzerland has the second highest rate (almost 18% in 2003) of foreign students in tertiary education, after Australia (slightly over 18%). [108] [109]

As might befit a country that plays home to innumerable international organizations, the Graduate Institute of International and Development Studies, located in Geneva, is not only continental Europe's oldest graduate school of international and development studies, but also widely believed to be one of its most prestigious.[110][111]

Many Nobel prizes were awarded to Swiss scientists, for example to the world-famous physicist Albert Einstein[112] in the field of physics who developed his Special relativity while working in Bern. More recently Vladimir Prelog, Heinrich Rohrer, Richard Ernst, Edmond Fischer, Rolf Zinkernagel and Kurt Wüthrich received Nobel prizes in the sciences. In total, 113 Nobel Prize winners in all fields stand in relation to Switzerland[113][114] and the Nobel Peace Prize was awarded nine times to organisations residing in Switzerland.[115]
The LHC tunnel. CERN is the world's largest laboratory and also the birthplace of the World Wide Web.[116]

Geneva and the nearby French department of Ain co-host the world's largest laboratory, CERN,[117] dedicated to particle physics research. Another important research center is the Paul Scherrer Institute. Notable inventions include lysergic acid diethylamide (LSD), the scanning tunneling microscope (Nobel prize) and Velcro. Some technologies enabled the exploration of new worlds such as the pressurized balloon of Auguste Piccard and the Bathyscaphe which permitted Jacques Piccard to reach the deepest point of the world's oceans.

Switzerland Space Agency, the Swiss Space Office, has been involved in various space technologies and programs. In addition it was one of the 10 founders of the European Space Agency in 1975 and is the seventh largest contributor to the ESA budget. In the private sector, several companies are implicated in the space industry such as Oerlikon Space[118] or Maxon Motors[119] who provide spacecraft structures.

Switzerland and the European Union

Switzerland voted against membership in the European Economic Area in a referendum in December 1992 and has since maintained and developed its relationships with the European Union (EU) and European countries through bilateral agreements. In March 2001, the Swiss people refused in a popular vote to start accession negotiations with the EU.[120] In recent years, the Swiss have brought their economic practices largely into conformity with those of the EU in many ways, in an effort to enhance their international competitiveness. The economy grew at 3% in 2010, 1.9% in 2011, and 1% in 2012.[121] Full EU membership is a long-term objective of some in the Swiss government, but there is considerable popular sentiment against this supported by the conservative SVP party. The western French-speaking areas and the urban regions of the rest of the country tend to be more pro-EU, however with far from any significant share of the population.[122][123]
The government has established an Integration Office under the Department of Foreign Affairs and the Department of Economic Affairs. To minimise the negative consequences of Switzerland's isolation from the rest of Europe, Bern and Brussels signed seven bilateral agreements to further liberalise trade ties. These agreements were signed in 1999 and took effect in 2001. This first series of bilateral agreements included the free movement of persons. A second series covering nine areas was signed in 2004 and has since been ratified, which includes the Schengen Treaty and the Dublin Convention besides others.[124] They continue to discuss further areas for cooperation.[125]

In 2006, Switzerland approved 1000 million francs of supportive investment in the poorer Southern and Central European countries in support of cooperation and positive ties to the EU as a whole. A further referendum will be needed to approve 300 million francs to support Romania and Bulgaria and their recent admission. The Swiss have also been under EU and sometimes international pressure to reduce banking secrecy and to raise tax rates to parity with the EU. Preparatory discussions are being opened in four new areas: opening up the electricity market, participation in the European GNSS project Galileo, cooperating with the European centre for disease prevention and recognising certificates of origin for food products.[126]

On 27 November 2008, the interior and justice ministers of European Union in Brussels announced Switzerland's accession to the Schengen passport-free zone from 12 December 2008. The land border checkpoints will remain in place only for goods movements, but should not run controls on people, though people entering the country had their passports checked until 29 March 2009 if they originated from a Schengen nation.[127]

On 9 February 2014, Swiss voters narrowly approved by 50.3% a ballot initiative launched by the national conservative Swiss People's Party (SVP/UDC) to restrict immigration, and thus reintroducing a quota system on the influx of foreigners. This initiative was mostly backed by rural (57.6% approvals), suburban (51.2% approvals), and isolated cities (51.3% approvals) of Switzerland as well as by a strong majority (69.2% approval) in the canton of Ticino, while metropolitan centers (58.5% rejection) and the French-speaking part (58.5% rejection) of Switzerland rather rejected it.[128] Some news commentators claim that this proposal de facto contradicts the bilateral agreements on the free movement of persons from these respective countries.[129][130]

Energy, infrastructure and environment

Switzerland has the tallest dams in Europe, among which the Mauvoisin Dam, in the Alps. Hydroelectricity is the most important domestic source of energy in the country.

Electricity generated in Switzerland is 56% from hydroelectricity and 39% from nuclear power, resulting in a nearly CO2-free electricity-generating network. On 18 May 2003, two anti-nuclear initiatives were turned down: Moratorium Plus, aimed at forbidding the building of new nuclear power plants (41.6% supported and 58.4% opposed),[131] and Electricity Without Nuclear (33.7% supported and 66.3% opposed).[132]

The former ten-year moratorium on the construction of new nuclear power plants was the result of a citizens' initiative voted on in 1990 which had passed with 54.5% Yes vs. 45.5% No votes. Plans for a new nuclear plant in the Canton of Bern have been put on hold after the accident at the Fukushima Daiichi power plant in 2011. The Swiss Federal Office of Energy (SFOE) is the office responsible for all questions relating to energy supply and energy use within the Federal Department of Environment, Transport, Energy and Communications (DETEC). The agency is supporting the 2000-watt society initiative to cut the nation's energy use by more than half by the year 2050.[133]

On 25 May 2011 the Swiss government announced that it plans to end its use of nuclear energy in the next 2 or 3 decades. "The government has voted for a phaseout because we want to ensure a secure and autonomous supply of energy", Energy Minister Doris Leuthard said that day at a press conference in Bern. "Fukushima showed that the risk of nuclear power is too high, which in turn has also increased the costs of this energy form." The first reactor would reportedly be taken offline in 2019 and the last one in 2034. Parliament will discuss the plan in June 2011, and there could be a referendum as well.[134]
Entrance of the new Lötschberg Base Tunnel, the third-longest railway tunnel in the world, under the old Lötschberg railway line. It is the first completed tunnel of the greater project AlpTransit.

The most dense rail network in Europe[43] of 5,063 km (3,146 mi) carries over 350 million passengers annually.[135] In 2007, each Swiss citizen travelled on average 2,258 km (1,403 mi) by rail, which makes them the keenest rail users.[136] The network is administered mainly by the Federal Railways, except in Graubünden, where the 366 km (227 mi) narrow gauge railway is operated by the Rhaetian Railways and includes some World Heritage lines.[137] The building of new railway base tunnels through the Alps is under way to reduce the time of travel between north and south through the AlpTransit project.

Swiss private-public managed road network is funded by road tolls and vehicle taxes. The Swiss autobahn/autoroute system requires the purchase of a vignette (toll sticker)—which costs 40 Swiss francs—for one calendar year in order to use its roadways, for both passenger cars and trucks. The Swiss autobahn/autoroute network has a total length of 1,638 km (1,018 mi) (as of 2000) and has, by an area of 41,290 km2 (15,940 sq mi), also one of the highest motorway densities in the world.[138] Zurich Airport is Switzerland's largest international flight gateway, which handled 22.8 million passengers in 2012.[139] The other international airports are Geneva Airport (13.9 million passengers in 2012),[140] EuroAirport Basel-Mulhouse-Freiburg which is located in France, Bern Airport, Lugano Airport, St. Gallen-Altenrhein Airport and Sion Airport. Swiss International Airlines is the flag carrier of Switzerland. Its main hub is Zürich.

Switzerland has one of the best environmental records among nations in the developed world;[141] it was one of the countries to sign the Kyoto Protocol in 1998 and ratified it in 2003. With Mexico and the Republic of Korea it forms the Environmental Integrity Group (EIG).[142] The country is heavily active in recycling and anti-littering regulations and is one of the top recyclers in the world, with 66% to 96% of recyclable materials being recycled, depending on the area of the country.[143]

In many places in Switzerland, household rubbish disposal is charged for. Rubbish (except dangerous items, batteries etc.) is only collected if it is in bags which either have a payment sticker attached, or in official bags with the surcharge paid at the time of purchase.[144] This gives a financial incentive to recycle as much as possible, since recycling is free.[145] Illegal disposal of garbage is not tolerated but usually the enforcement of such laws is limited to violations that involve the unlawful disposal of larger volumes at traffic intersections and public areas. Fines for not paying the disposal fee range from CHF 200–500.[146]

Switzerland also has internationally the most efficient system to recycle old newspapers and cardboard materials. Publicly organised collection by volunteers and economical railway transport logistics started as early as 1865 under the leadership of the notable industrialist Hans Caspar Escher (Escher Wyss AG) when the first modern Swiss paper manufacturing plant was built in Biberist.[147]

Demographics

In 2012, Switzerland's population slightly exceeded eight million. The Swiss population quadrupled between 1800 and 1990.
In 2012, resident foreigners made up 23.3% of the population.[148] Most of these (64%) were from European Union or EFTA countries.[149] Italians were the largest single group of foreigners with 15.6% of total foreign population. They were closely followed by Germans (15.2%), immigrants from Portugal (12.7%), France (5.6%), Serbia (5.3%), Turkey (3.8%), Spain (3.7%), and Austria (2%). Immigrants from Sri Lanka, most of them former Tamil refugees, were the largest group among people of Asian origin (6.3%).[149] Additionally, the figures from 2012 show that 34.7% of the permanent resident population aged 15 or over in Switzerland, i.e. 2,335,000 persons, had an immigration background. A third of this population (853,000) held Swiss citizenship. Four fifths of persons with an immigration background were themselves immigrants (first generation foreigners and native-born and naturalised Swiss citizens), whereas one fifth were born in Switzerland (second generation foreigners and native-born and naturalised Swiss citizens).[150]

Languages

Official languages in Switzerland (total / Swiss population):[151]
   German (65.3%; 73.2%)
   French (22.4%; 23.1%)
   Italian (8.4%; 6.1%)
   Romansh (0.54%; 0.7%)

Switzerland has four official languages: principally German (65.3% total population share, with foreign residents; 73.2% of residents with Swiss citizenship, in 2011); French (22.4%; 23.1%) in the west; Italian (8.4%; 6.1%) in the south.[151] Romansh (0.6%; 0.7%), a Romance language spoken locally in the southeastern trilingual canton of Graubünden, is designated by the Federal Constitution as a national language along with German, French and Italian (Article 4 of the Constitution), and as official language if the authorities communicate with persons of Romansh language (Article 70), but federal laws and other official acts do not need to be decreed in this language.

In 2011, the languages most spoken at home among permanent residents aged 15 and older were: Swiss German (4,027,917, or 61.1%); French (1,523,094, 23.1%); Standard German (637,439, 9.7%); Italian (545,274, 8.2%); Ticinese and Grisons (107,973, 1.6%); Romansh (37,490, 0.57%); and English (278,407, 4.2%). Speakers of other languages at home numbered 1,382,508, or 16.5% of the population.[152]

The federal government is obliged to communicate in the official languages, and in the federal parliament simultaneous translation is provided from and into German, French and Italian.[153]

Aside from the official forms of their respective languages, the four linguistic regions of Switzerland also have their local dialectal forms. The role played by dialects in each linguistic region varies dramatically: in the German-speaking regions, Swiss German dialects became ever more prevalent since the second half of the 20th century, especially in the media, such as radio and television, and are used as an everyday language, while (the Swiss variety of) Standard German is used for almost all written situations (c.f. diglossic usage of a language).[154] Conversely, in the French-speaking regions the local dialects have almost disappeared (only 6.3% of the population of Valais, 3.9% of Fribourg, and 3.1% of Jura still spoke dialects at the end of the 20th century), while in the Italian-speaking regions dialects are mostly limited to family settings and casual conversation.[154]

The official languages (German, French and Italian) have terms, not used outside of Switzerland, known as Helvetisms. German Helvetisms are, roughly spoken, a large group of words typical of Swiss Standard German, which do not appear in either of Standard German, nor Standard German dialects. E.g. terms from Switzerland's surrounding language cultures (German Billette[155] from French), from similar term in another language (Italian azione used not only as act but also as discount from German Aktion).[156] The French spoken in Switzerland has similar terms, which are equally known as Helvetisms. The most frequent characteristics of Helvetisms are in vocabulary, phrases, and pronunciation, but certain Helvetisms denote themselves as special in syntax and orthography likewise. Duden, one of the prescriptive sources for Standard German, is aware of about 3000 Helvetisms.[156] Current French dictionaries, such as the Petit Larousse, include several hundred Helvetisms.[157]

Learning one of the other national languages at school is compulsory for all Swiss students, so many Swiss are supposed to be at least bilingual, especially those belonging to minorities.[158]

Health

Swiss citizens are universally required to buy health insurance from private insurance companies, which in turn are required to accept every applicant. While the cost of the system is among the highest, the system compares well with other European countries in terms of health outcomes, so patients are largely satisfied with it. In 2012, life expectancy at birth was 80.4 years for men and 84.7 years for women.[159] These are the world's highest life expectancy.[160][161] However, spending on health is particularly high, with 11.4% of GDP (2010), however in par with Germany and France (11.6%) and other European countries, but far less than in USA (17.6%).[162] From 1990, a steady increase is observed, reflecting the high prices of the services provided.[163] With aging populations and new healthcare technologies, health spending will likely continue to rise.[163]

Urbanization

Urbanization in the Rhone Valley (outskirts of Sion)

Between two thirds and three quarters of the population live in urban areas.[164][165] Switzerland has gone from a largely rural country to an urban one in just 70 years. Since 1935 urban development has claimed as much of the Swiss landscape as it did during the previous 2,000 years. This urban sprawl does not only affect the plateau but also the Jura and the Alpine foothills[166] and there are growing concerns about land use.[167] However from the beginning of the 21st century, the population growth in urban areas is higher than in the countryside.[165]

Switzerland has a dense network of cities, where large, medium and small cities are complementary.[165] The plateau is very densely populated with about 450 people per km2 and the landscape continually shows signs of man's presence.[168] The weight of the largest metropolitan areas, which are Zürich, GenevaLausanne, Basel and Bern tend to increase.[165] In international comparison the importance of these urban areas is stronger than their number of inhabitants suggests.[165] In addition the two main centers of Zürich and Geneva are recognized for their particularly great quality of life.[169]

Switzerland has no official state religion, though most of the cantons (except Geneva and Neuchâtel) recognize official churches, which are either the Catholic Church or the (Protestant) Swiss Reformed Church. These churches, and in some cantons also the Old Catholic Church and Jewish congregations, are financed by official taxation of adherents.[171]
The reformed church of Glarus

As of 2012 Christianity is the predominant religion of Switzerland, divided between the Catholic Church (38.2% of the population), the Swiss Reformed Church (26.9%) and other Christian denominations (5.7%). Geneva converted to Protestantism in 1536, just before John Calvin arrived there. Immigration has brought Islam (4.9%) and Eastern Orthodoxy (around 2%) as sizeable minority religions.[170] As of the 2000 census other Christian minority communities include Neo-Pietism (0.44%), Pentecostalism (0.28%, mostly incorporated in the Schweizer Pfingstmission), Methodism (0.13%), the New Apostolic Church (0.45%), Jehovah's Witnesses (0.28%), other Protestant denominations (0.20%), the Old Catholic Church (0.18%), other Christian denominations (0.20%). Non-Christian religions are Hinduism (0.38%), Buddhism (0.29%), Judaism (0.25%) and others (0.11%); 4.3% did not make a statement. 11.1% in 2000 and already 21.4% in 2012 declared themselves as unchurched i.e. not affiliated with any church or other religious body (Agnostic, Atheist, or just not related to any official religion).[170][172]

The country was historically about evenly balanced between Catholic and Protestant, with a complex patchwork of majorities over most of the country. One canton, Appenzell, was officially divided into Catholic and Protestant sections in 1597. The larger cities and their cantons (Bern, Geneva, Lausanne, Zürich and Basel) used to be predominantly Protestant. Central Switzerland, the Valais, the Ticino, Appenzell Innerrhodes, the Jura, and Fribourg are traditionally Catholic. The Swiss Constitution of 1848, under the recent impression of the clashes of Catholic vs. Protestant cantons that culminated in the Sonderbundskrieg, consciously defines a consociational state, allowing the peaceful co-existence of Catholics and Protestants. A 1980 initiative calling for the complete separation of church and state was rejected by 78.9% of the voters.[173] Some traditionally Protestant cantons and cities nowadays have a slight Catholic majority, not because they were growing in members, quite the contrary, but only because since about 1970 a steadily growing minority became not affiliated with any church or other religious body (21.6% in Switzerland, 2012) especially in traditionally Protestant regions, such as Basel-City (42%), canton of Neuchâtel (38%), canton of Geneva (35%), canton of Vaud (26%), or Zürich city (city: >25%; canton: 23%).[170]

Culture

Three of Europe's major languages are official in Switzerland. Swiss culture is characterised by diversity, which is reflected in a wide range of traditional customs.[174] A region may be in some ways strongly culturally connected to the neighbouring country that shares its language, the country itself being rooted in western European culture.[175] The linguistically isolated Romansh culture in Graubünden in eastern Switzerland constitutes an exception, it survives only in the upper valleys of the Rhine and the Inn and strives to maintain its rare linguistic tradition.

Switzerland is home to many notable contributors to literature, art, architecture, music and sciences. In addition the country attracted a number of creative persons during time of unrest or war in Europe.[176] Some 1000 museums are distributed through the country; the number has more than tripled since 1950.[177] Among the most important cultural performances held annually are the Lucerne Festival,[178] the Montreux Jazz Festival[179] and the Locarno International Film Festival.[180]

Alpine symbolism has played an essential role in shaping the history of the country and the Swiss national identity.[11][181] Nowadays some concentrated mountain areas have a strong highly energetic ski resort culture in winter, and a hiking (ger: das Wandern) or Mountain biking culture in summer. Other areas throughout the year have a recreational culture that caters to tourism, yet the quieter seasons are spring and autumn when there are fewer visitors. A traditional farmer and herder culture also predominates in many areas and small farms are omnipresent outside the cities. Folk art is kept alive in organisations all over the country. In Switzerland it is mostly expressed in music, dance, poetry, wood carving and embroidery. The alphorn, a trumpet-like musical instrument made of wood, has become alongside yodeling and the accordion an epitome of traditional Swiss music.[182][183]

Literature

Jean-Jacques Rousseau was not only a writer but also an influential philosopher of the eighteenth century[184] (his statue in Geneva).

As the Confederation, from its foundation in 1291, was almost exclusively composed of German-speaking regions, the earliest forms of literature are in German. In the 18th century, French became the fashionable language in Bern and elsewhere, while the influence of the French-speaking allies and subject lands was more marked than before.[185]

Among the classics of Swiss German literature are Jeremias Gotthelf (1797–1854) and Gottfried Keller (1819–1890). The undisputed giants of 20th century Swiss literature are Max Frisch (1911–91) and Friedrich Dürrenmatt (1921–90), whose repertoire includes Die Physiker (The Physicists) and Das Versprechen (The Pledge), released in 2001 as a Hollywood film.[186]

Prominent French-speaking writers were Jean-Jacques Rousseau (1712–1778) and Germaine de Staël (1766–1817). More recent authors include Charles Ferdinand Ramuz (1878–1947), whose novels describe the lives of peasants and mountain dwellers, set in a harsh environment and Blaise Cendrars (born Frédéric Sauser, 1887–1961).[186] Also Italian and Romansh-speaking authors contributed but in more modest way given their small number.

Probably the most famous Swiss literary creation, Heidi, the story of an orphan girl who lives with her grandfather in the Alps, is one of the most popular children's books ever and has come to be a symbol of Switzerland. Her creator, Johanna Spyri (1827–1901), wrote a number of other books around similar themes.[186]

Media

The freedom of the press and the right to free expression is guaranteed in the federal constitution of Switzerland.[187] The Swiss News Agency (SNA) broadcasts information around-the-clock in three of the four national languages—on politics, economics, society and culture. The SNA supplies almost all Swiss media and a couple dozen foreign media services with its news.[187]
Switzerland has historically boasted the greatest number of newspaper titles published in proportion to its population and size.[188] The most influential newspapers are the German-language Tages-Anzeiger and Neue Zürcher Zeitung NZZ, and the French-language Le Temps, but almost every city has at least one local newspaper. The cultural diversity accounts for a large number of newspapers.[188]

The government exerts greater control over broadcast media than print media, especially due to finance and licensing.[188] The Swiss Broadcasting Corporation, whose name was recently changed to SRG SSR idée suisse, is charged with the production and broadcast of radio and television programs. SRG SSR studios are distributed throughout the various language regions. Radio content is produced in six central and four regional studios while the television programs are produced in Geneva, Zürich and Lugano. An extensive cable network also allows most Swiss to access the programs from neighboring countries.[188]

Sports

Skiing, snowboarding and mountaineering are among the most popular sports in Switzerland, the nature of the country being particularly suited for such activities.[189] Winter sports are practiced by the natives and tourists since the second half of the 19th century with the invention of bobsleigh in St. Moritz.[190] The first world ski championships were held in Mürren (1931) and St. Moritz (1934). The latter town hosted the second Winter Olympic Games in 1928 and the fifth edition in 1948. Among the most successful skiers and world champions are Pirmin Zurbriggen and Didier Cuche.

Swiss are fans of football and the national team is nicknamed the 'Nati'. The headquarters of the sport's governing body, the International Federation of Association Football (FIFA), is located in Zürich. Switzerland hosted the 1954 FIFA World Cup, and was the joint host, with Austria, of the Euro 2008 tournament. The Swiss Super League is the nation's professional club league. For the Brasil 2014 World Cup finals tournament, the country's German-speaking cantons will be closely monitored by local police forces to prevent celebrations beyond one hour after matches end.[191] Europe's highest football pitch, at 2,000 metres (6,600 ft) above sea level, is located in Switzerland and is named the Ottmar Hitzfeld Stadium.[192]

Many Swiss also follow ice hockey and support one of the 12 clubs in the League A, which is the most attended league in Europe.[193] In 2009, Switzerland hosted the IIHF World Championship for the 10th time.[194] It also became World Vice-Champion in 2013. The numerous lakes make Switzerland an attractive place for sailing. The largest, Lake Geneva, is the home of the sailing team Alinghi which was the first European team to win the America's Cup in 2003 and which successfully defended the title in 2007. Tennis has become an increasingly popular sport, and Swiss players such as Martina Hingis, Roger Federer, and most recently, Stanislas Wawrinka have won multiple Grand Slams.
In an eight-year span, Roger Federer has won a record 17 Grand Slam singles titles, making him the most successful men's tennis player ever.[195]

Motorsport racecourses and events were banned in Switzerland following the 1955 Le Mans disaster with exception to events such as Hillclimbing. During this period, the country still produced successful racing drivers such as Clay Regazzoni, Sebastian Buemi, Jo Siffert, Dominique Aegerter and successful World Touring Car Championship driver Alain Menu. Switzerland also won the A1GP World Cup of Motorsport in 2007–08 with driver Neel Jani. Swiss motorcycle racer Thomas Lüthi won the 2005 MotoGP World Championship in the 125cc category. In June 2007 the Swiss National Council, one house of the Federal Assembly of Switzerland, voted to overturn the ban, however the other house, the Swiss Council of States rejected the change and the ban remains in place.[196][197]

Traditional sports include Swiss wrestling or "Schwingen". It is an old tradition from the rural central cantons and considered the national sport by some. Hornussen is another indigenous Swiss sport, which is like a cross between baseball and golf.[198] Steinstossen is the Swiss variant of stone put, a competition in throwing a heavy stone. Practiced only among the alpine population since prehistoric times, it is recorded to have taken place in Basel in the 13th century. It is also central to the Unspunnenfest, first held in 1805, with its symbol the 83.5 kg stone named Unspunnenstein.[199]

Cuisine

Fondue is melted cheese, into which bread is dipped

The cuisine of Switzerland is multifaceted. While some dishes such as fondue, raclette or rösti are omnipresent through the country, each region developed its own gastronomy according to the differences of climate and languages.[200] [201] Traditional Swiss cuisine uses ingredients similar to those in other European countries, as well as unique dairy products and cheeses such as Gruyère or Emmental, produced in the valleys of Gruyères and Emmental. The number of fine-dining establishments is high, particularly in western Switzerland.[202][203]

Chocolate had been made in Switzerland since the 18th century but it gained its reputation at the end of the 19th century with the invention of modern techniques such as conching and tempering which enabled its production on a high quality level. Also a breakthrough was the invention of solid milk chocolate in 1875 by Daniel Peter. The Swiss are the world's largest consumers of chocolate.[204][205]

The most popular alcoholic drink in Switzerland is wine. Switzerland is notable for the variety of grapes grown because of the large variations in terroirs, with their specific mixes of soil, air, altitude and light. Swiss wine is produced mainly in Valais, Vaud (Lavaux), Geneva and Ticino, with a small majority of white wines. Vineyards have been cultivated in Switzerland since the Roman era, even though certain traces can be found of a more ancient origin. The most widespread varieties are the Chasselas (called Fendant in Valais) and Pinot noir. The Merlot is the main variety produced in Ticino.[206][207]

Iron fertilization

Iron fertilization

From Wikipedia, the free encyclopedia

An oceanic phytoplankton bloom in the South Atlantic Ocean, off the coast of Argentina covering an area about 300 miles (480 km) by 50 miles

Iron fertilization is the intentional introduction of iron to the upper ocean to stimulate a phytoplankton bloom. This is intended to enhance biological productivity, which can benefit the marine food chain and is under investigation in hopes of increasing carbon dioxide removal from the atmosphere. Iron is a trace element necessary for photosynthesis in all plants. It is highly insoluble in sea water and is often the limiting nutrient for phytoplankton growth. Large algal blooms can be created by supplying iron to iron-deficient ocean waters.

A number of ocean labs, scientists and businesses are exploring fertilization as a means to sequester atmospheric carbon dioxide in the deep ocean, and to increase marine biological productivity which is likely in decline as a result of climate change. Since 1993, thirteen international research teams have completed ocean trials demonstrating that phytoplankton blooms can be stimulated by iron addition.[1] However, controversy remains over the effectiveness of atmospheric CO
2
sequestration and ecological effects.[2] The most recent open ocean trials of ocean iron fertilization were in 2009 (January to March) in the South Atlantic by project LOHAFEX, and in July 2012 in the North Pacific off the coast of British Columbia, Canada, by the Haida Salmon Restoration Corporation (HSRC).[3]

Fertilization also occurs naturally when upwellings bring nutrient-rich water to the surface, as occurs when ocean currents meet an ocean bank or a sea mount. This form of fertilization produces the world's largest marine habitats. Fertilization can also occur when weather carries wind blown dust long distances over the ocean, or iron-rich minerals are carried into the ocean by glaciers,[4] rivers and icebergs.[5]

History

Consideration of iron's importance to phytoplankton growth and photosynthesis dates back to the 1930s when English biologist Joseph Hart speculated that the ocean's great "desolate zones" (areas apparently rich in nutrients, but lacking in plankton activity or other sea life) might simply be iron deficient.[6] Little further scientific discussion of this issue was recorded until the 1980s, when oceanographer John Martin renewed controversy on the topic with his marine water nutrient analyses. His studies indicated it was indeed a scarcity of iron micronutrients that was limiting phytoplankton growth and overall productivity in these "desolate" regions, which came to be called "High Nutrient, Low Chlorophyll" (HNLC) zones.[6]

In an article in the scientific journal Nature (February 1988; 331 (6157): 570ff.), John Gribbin was the first scientist to publicly suggest that the upcoming greenhouse effect might be reduced by adding large amounts of soluble iron compounds to the oceans of the world as a fertilizer for the aquatic plants.

Martin's famous 1988 quip four months later at Woods Hole Oceanographic Institution, "Give me a half a tanker of iron and I will give you another ice age",[6][7] drove a decade of research whose findings suggested that iron deficiency was not merely impacting ocean ecosystems, it also offered a key to mitigating climate change as well.

Perhaps the most dramatic support for Martin's hypothesis was seen in the aftermath of the 1991 eruption of Mount Pinatubo in the Philippines.[citation needed] Environmental scientist Andrew Watson analyzed global data from that eruption and calculated that it deposited approximately 40,000 tons of iron dust into the oceans worldwide. This single fertilization event generated an easily observed global decline in atmospheric CO
2
and a parallel pulsed increase in oxygen levels.[8]

Experiments

Martin hypothesized that increasing phytoplankton photosynthesis could slow or even reverse global warming by sequestering enormous volumes of CO
2
in the sea. He died shortly thereafter during preparations for Ironex I,[9] a proof of concept research voyage, which was successfully carried out near the Galapagos Islands in 1993 by his colleagues at Moss Landing Marine Laboratories.[6] Since then 9 international ocean studies have examined the fertilization effects of iron:
  • LOHAFEX (Indian and German Iron Fertilization Experiment), 2009 [26][27][28] Despite widespread opposition to LOHAFEX, on 26 January 2009 the German Federal Ministry of Education and Research (BMBF) gave clearance for this fertilization experiment to commence. The experiment was carried out in waters low in silicic acid which is likely to affect the efficacy of carbon sequestration.[29] A 900 square kilometers (350 sq mi) portion of the southwest Atlantic Ocean was fertilized with iron sulfate. A large phytoplankton bloom was triggered, however this bloom did not contain diatoms because the fertilized location was already depleted in silicic acid, an essential nutrient for diatom growth.[29] In the absence of diatoms, a relatively small amount of carbon was sequestered, because other phytoplankton are vulnerable to predation by zooplankton and do not sink rapidly upon death.[29] These poor sequestration results have caused some to suggest that ocean iron fertilization is not an effective carbon mitigation strategy in general. However, prior ocean fertilization experiments in high silica locations have observed much higher carbon sequestration rates because of diatom growth. LOHAFEX has just confirmed that the carbon sequestration potential depends strongly upon careful choice of location.[29]

Science

The maximum possible result from iron fertilization, assuming the most favourable conditions and disregarding practical considerations, is 0.29W/m2 of globally averaged negative forcing,[32] which is almost sufficient to reverse the warming effect of about 1/6 of current levels of anthropogenic CO
2
emissions. It is notable, however, that the addition of silicic acid or choosing the proper location could, at least theoretically, eliminate and exceed all man-made CO
2
.

Role of iron

About 70% of the world's surface is covered in oceans, and the upper part of these (where light can penetrate) is inhabited by algae. In some oceans, the growth and reproduction of these algae is limited by the amount of iron in the seawater. Iron is a vital micronutrient for phytoplankton growth and photosynthesis that has historically been delivered to the pelagic sea by dust storms from arid lands.

This Aeolian dust contains 3–5% iron and its deposition has fallen nearly 25% in recent decades.[33]

The Redfield ratio describes the relative atomic concentrations of critical nutrients in plankton biomass and is conventionally written "106 C: 16 N: 1 P." This expresses the fact that one atom of phosphorus and 16 of nitrogen are required to "fix" 106 carbon atoms (or 106 molecules of CO
2
). Recent research has expanded this constant to "106 C: 16 N: 1 P: .001 Fe" signifying that in iron deficient conditions each atom of iron can fix 106,000 atoms of carbon,[34] or on a mass basis, each kilogram of iron can fix 83,000 kg of carbon dioxide. The 2004 EIFEX experiment reported a carbon dioxide to iron export ratio of nearly 3000 to 1. The atomic ratio would be approximately: "3000 C: 58,000 N: 3,600 P: 1 Fe".[35]

Therefore small amounts of iron (measured by mass parts per trillion) in "desolate" HNLC zones can trigger large phytoplankton blooms. Recent marine trials suggest that one kilogram of fine iron particles may generate well over 100,000 kilograms of plankton biomass. The size of the iron particles is critical, however, and particles of 0.5–1 micrometer or less seem to be ideal both in terms of sink rate and bioavailability. Particles this small are not only easier for cyanobacteria and other phytoplankton to incorporate, the churning of surface waters keeps them in the euphotic or sunlit biologically active depths without sinking for long periods of time.

Volcanic ash as a source of iron

Large amounts of eolian (wind deposited) sediment are deposited annually in the world’s oceans. These deposits have long been thought to be the main source of iron to the surface ocean, and therefore the main source of iron for biological productivity. Recent studies suggest that volcanic ash has a significant role in supplying the world’s oceans with iron as well.[36] Volcanic ash is composed of glass shards, pyrogenic minerals, lithic particles, and other forms of ash which release nutrients at different rates depending on structure and the type of reaction caused by contact with water.[37]

Murray et al. recently assessed the relationship between increases of biogenic opal in the sediment record with increased iron accumulation over the last million years.[38] In August 2008, an eruption in the Aleutian Islands, Alaska deposited ash in the nutrient-limited Northeast Pacific. There is strong evidence that this ash and iron deposition resulted in one of the largest phytoplankton blooms observed in the subarctic.[39]

Carbon sequestration

Air-sea exchange of CO
2

Previous instances of biological carbon sequestration have triggered major climatic changes in which the temperature of the planet was lowered, such as the Azolla event. Plankton that generate calcium or silicon carbonate skeletons, such as diatoms, coccolithophores and foraminifera, account for most direct carbon sequestration. When these organisms die their carbonate skeletons sink relatively quickly and form a major component of the carbon-rich deep sea precipitation known as marine snow. Marine snow also includes fish fecal pellets and other organic detritus, and can be seen steadily falling thousands of meters below active plankton blooms.[40]

Of the carbon-rich biomass generated by plankton blooms, half (or more) is generally consumed by grazing organisms (zooplankton, krill, small fish, etc.) but 20 to 30% sinks below 200 meters (660 ft) into the colder water strata below the thermocline.[citation needed] Much of this fixed carbon continues falling into the abyss, but a substantial percentage is redissolved and remineralized. At this depth, however, this carbon is now suspended in deep currents and effectively isolated from the atmosphere for centuries. (The surface to benthic cycling time for the ocean is approximately 4,000 years.)

Analysis and quantification

Evaluation of the biological effects and verification of the amount of carbon actually sequestered by any particular bloom requires a variety of measurements, including a combination of ship-borne and remote sampling, submarine filtration traps, tracking buoy spectroscopy and satellite telemetry.
Unpredictable ocean currents have been known to remove experimental iron patches from the pelagic zone, invalidating the experiment.

The potential of iron fertilization as a geoengineering technique to tackle global warming is illustrated by the following figures. If phytoplankton converted all the nitrate and phosphate present in the surface mixed layer across the entire Antarctic circumpolar current into organic carbon, the resulting carbon dioxide deficit could be compensated by uptake from the atmosphere amounting to about 0.8 to 1.4 gigatonnes of carbon per year.[41] This quantity is comparable in magnitude to annual anthropogenic fossil fuels combustion of approximately 6 gigatonnes. It should be noted that the Antarctic circumpolar current region is only one of several in which iron fertilization could be conducted—the Galapagos islands area being another potentially suitable location.

Dimethyl sulfide and clouds

Schematic diagram of the CLAW hypothesis (Charlson et al., 1987)[42]

Some species of plankton produce dimethyl sulfide (DMS), a portion of which enters the atmosphere where it is oxidized by hydroxyl radicals (OH), atomic chlorine (Cl) and bromine monoxide (BrO) to form sulfate particles, and potentially increase the cloud cover. This may increase the albedo of the planet and so cause cooling - this proposed mechanism is central to the CLAW hypothesis.[42] This is one of the examples used by James Lovelock to illustrate his Gaia hypothesis.[43]

During the Southern Ocean Iron Enrichment Experiments (SOFeX), DMS concentrations increased by a factor of four inside the fertilized patch. Widescale iron fertilization of the Southern Ocean could lead to significant sulfur-triggered cooling in addition to that due to the increased CO
2
uptake and that due to the ocean's albedo increase, however the amount of cooling by this particular effect is very uncertain.[44]

Financial opportunities

Since the advent of the Kyoto Protocol, several countries and the European Union have established carbon offset markets which trade certified emission reduction credits (CERs) and other types of carbon credit instruments internationally. In 2007 CERs sold for approximately €15–20/ton COe
2
.[45]
Iron fertilization is relatively inexpensive compared to scrubbing, direct injection and other industrial approaches, and can theoretically sequester for less than €5/ton CO
2
, creating a substantial return.[46] In August, 2010, Russia established a minimum price of €10/ton for offsets to reduce uncertainty for offset providers.[47] Scientists have reported a minimum 6–12% decline in global plankton production since 1980,[33][48] A full-scale international plankton restoration program could regenerate approximately 3–5 billion tons of sequestration capacity worth €50-100 billion in carbon offset value. Given this potential return on investment, carbon traders and offset customers are watching the progress of this technology with interest.[49] However, a recent study indicates the cost versus benefits of iron fertilization puts it behind carbon capture and storage and carbon taxes.[50]

Multilateral reaction

The parties to the London Dumping Convention adopted a non-binding resolution in 2008 on fertilization (labeled LC-LP.1(2008)). The resolution states that ocean fertilization activities, other than legitimate scientific research, "should be considered as contrary to the aims of the Convention and Protocol and do not currently qualify for any exemption from the definition of dumping".[51]

An Assessment Framework for Scientific Research Involving Ocean Fertilization, regulating the dumping of wastes at sea (labeled LC-LP.2(2010)) was adopted by the Contracting Parties to the Convention in October 2010 (LC 32/LP 5).[52]

Sequestration definitions

Carbon is not considered "sequestered" unless it settles to the ocean floor where it may remain for millions of years. Most of the carbon that sinks beneath plankton blooms is dissolved and remineralized well above the seafloor and will eventually (days to centuries) return to the atmosphere, negating the original effect.[citation needed]

Advocates argue that modern climate scientists and Kyoto Protocol policy makers define sequestration in much shorter time frames. For example, they recognize trees and grasslands as important carbon sinks. Forest biomass only sequesters carbon for decades, but carbon that sinks below the marine thermocline (100–200 meters) is effectively removed from the atmosphere for hundreds of years, whether it is remineralized or not. Since deep ocean currents take so long to resurface, their carbon content is effectively sequestered by the criterion in use today.[citation needed]

Debate

While ocean iron fertilization could represent a potent means to slow global warming current debate raises a variety of concerns.

Precautionary principle

The precautionary principle (PP) states that if an action or policy has a suspected risk of causing harm, in the absence of scientific consensus, the burden of proof that it is not harmful falls on those who would take the action. The side effects of large-scale iron fertilization are not yet known.
Creating phytoplankton blooms in naturally iron-poor areas of the ocean is like watering the desert: in effect it changes one type of ecosystem into another.

The argument can be applied in reverse, by considering emissions to be the action and remediation an attempt to partially offset the damage.

20th-century phytoplankton decline

While advocates argue that iron addition would help to reverse a supposed decline in phytoplankton, this decline may not be real. One study reported a decline in ocean productivity comparing the 1979–1986 and 1997–2000 periods,[53] but two others found increases in phytoplankton.[54][55]

Comparison to prior phytoplankton cycles

Fertilization advocates respond that similar algal blooms have occurred naturally for millions of years with no observed ill effects. The Azolla event occurred around 49 million years ago and accomplished what fertilization is intended to achieve (but on a larger scale).

Sequestration efficiency

Fertilization may sequester too little carbon per bloom, supporting the food chain rather than raining on the ocean floor, and thus require too many seeding voyages to be practical.[15][56] A 2009 Indo-German team of scientists examined the potential of the south-western Atlantic to sequester significant amounts of carbon dioxide, but found few positive results.[57]

The counter-argument to this is that the low sequestration estimates that emerged from some ocean trials are largely due to these factors:[citation needed]
  1. Data: none of the ocean trials had enough boat time to monitor their blooms for more than five weeks, confining their measurements to that period. Blooms generally last 60–90 days with the heaviest "precipitation" occurring during the last two months.
  2. Scale: most trials used less than 1,000 kilograms (2,200 lb) of iron and thus created small blooms that were quickly devoured by opportunistic zooplankton, krill, and fish that swarmed into the seeded region.
Some ocean trials reported positive results. IronEx II reported conversion of 1,000 kilograms (2,200 lb) to carbonaceous biomass equivalent to one hundred full-grown redwoods within two weeks. Eifex recorded fixation ratios of nearly 300,000 to 1.

Current estimates of the amount of iron required to restore all the lost plankton and sequester 3 gigatons/year of CO
2
range widely, from approximately 2 hundred thousand tons/year to over 4 million tons/year. The latter scenario involves 16 supertanker loads of iron and a projected cost of approximately €20 billion ($27 billion).[citation needed]

Ecological issues

Algal blooms

A "red tide" off the coast of La Jolla, San Diego, California.

Critics are concerned that fertilization will create harmful algal blooms (HAB). The species that respond most strongly to fertilization vary by location and other factors and could possibly include species that cause red tides and other toxic phenomena. These factors affect only near-shore waters, although they show that increased phytoplankton populations are not universally benign.[citation needed]

Most species of phytoplankton are harmless or beneficial, given that they constitute the base of the marine food chain. Fertilization increases phytoplankton only in the deep oceans (far from shore) where iron deficiency is the problem. Most coastal waters are replete with iron and adding more has no useful effect.[citation needed]

A 2010 study of iron fertilization in an oceanic high-nitrate, low-chlorophyll environment, however, found that fertilized Pseudo-nitzschia diatom spp., which are generally nontoxic in the open ocean, began producing toxic levels of domoic acid. Even short-lived blooms containing such toxins could have detrimental effects on marine food webs.[58]

Deep water oxygen levels

When organic bloom detritus sinks into the abyss, a significant fraction will be devoured by bacteria, other microorganisms and deep sea animals which also consume oxygen. A large enough bloom could render certain regions of the sea deep beneath it anoxic and threaten other benthic species.[citation needed]However this would entail the removal of oxygen from thousands of cubic km of benthic water beneath a bloom and so this seems unlikely.

The largest plankton replenishment projects under consideration are less than 10% the size of most natural wind-fed blooms. In the wake of major dust storms, natural blooms have been studied since the beginning of the 20th century and no such deep water dieoffs have been reported.[citation needed]

Ecosystem effects

Depending upon the composition and timing of delivery, iron infusions could preferentially favor certain species and alter surface ecosystems to unknown effect. Population explosions of jellyfish, that disturb the food chain impacting whale populations or fisheries is unlikely as iron fertilization experiments that are conducted in high-nutrient, low-chlorophyll waters favor the growth of larger diatoms over small flagellates. This has been shown to lead to increased abundance of fish and whales over jellyfish[59] A 2010 study shows that iron enrichment stimulates toxic diatom production in high-nitrate, low-chlorophyll areas [60] which, the authors argue, raises "serious concerns over the net benefit and sustainability of large-scale iron fertilizations".

However, CO

-induced surface water heating and rising carbonic acidity are already shifting population distributions for phytoplankton, zooplankton and many other creatures. Optimal fertilization could potentially help restore lost/threatened ecosystem services.[citation needed]

Conclusion and further research

Critics and advocates generally agree that most questions on the impact, safety and efficacy of ocean iron fertilization can only be answered by much larger studies.

A statement published in Science in 2008 maintained that it would be
premature to sell carbon offsets from the first generation of commercial-scale OIF experiments unless there is better demonstration that OIF effectively removes CO2, retains that carbon in the ocean for a quantifiable amount of time, and has acceptable and predictable environmental impacts.[61]
