Definition and usage
"Global commons" is a term typically used to describe international, supranational, and global resource domains in which common-pool resources are found. In economics, common goods are rivalrous and non-excludable, constituting one of the four main types of goods. A common-pool resource, also called a common property resource, is a special case of a common good (or public good)
whose size or characteristics makes it costly, but not impossible, to
exclude potential users. Examples include both natural or human-made
resource domains (e.g., a "fishing hole" or an irrigation system).
Unlike global public goods,
global common-pool resources face problems of congestion, overuse, or
degradation because they are subtractable (which makes them rivalrous).
The term "commons" originates from the term common land in the British Isles. "Commoners rights" referred to traditional rights held by commoners, such as mowing meadows for hay or grazing livestock on common land held in the open field system of old English common law. Enclosure was the process that ended those traditional rights, converting open fields to private property. Today, many commons still exist in England, Wales, Scotland, and the United States, although their extent is much reduced from the millions of acres that existed until the 17th century. There are still over 7,000 registered commons in England alone.
The term "global commons" is typically used to indicate the earth's shared natural resources, such as the deep oceans, the atmosphere, outer space and the Northern and Southern polar regions, the Antarctic in particular.
According to the World Conservation Strategy, a report on conservation published by the International Union for Conservation of Nature and Natural Resources (IUCN) in collaboration with UNESCO and with the support of the United Nations Environment Programme (UNEP) and the World Wildlife Fund (WWF):
A commons is a tract of land or water owned or used jointly by the members of a community. The global commons includes those parts of the Earth's surface beyond national jurisdictions — notably the open ocean and the living resources found there — or held in common — notably the atmosphere. The only landmass that may be regarded as part of the global commons is Antarctica ...
Today, the Internet, World Wide Web and resulting cyberspace are often referred to as global commons.
Other usages sometimes include references to open access information
of all kinds, including arts and culture, language and science, though
these are more formally referred to as the common heritage of mankind.
Management of the global commons
The
key challenge of the global commons is the design of governance
structures and management systems capable of addressing the complexity
of multiple public and private interests, subject to often unpredictable
changes, ranging from the local to the global level.
As with global public goods, management of the global commons requires
pluralistic legal entities, usually international and supranational,
public and private, structured to match the diversity of interests and
the type of resource to be managed, and stringent enough with adequate
incentives to ensure compliance. Such management systems are necessary to avoid, at the global level, the classic tragedy of the commons, in which common resources become over-exploited.
There are several key differences in management of resources in the global commons from those of the commons, in general.
There are obvious differences in scale of both the resources and the
number of users at the local versus the global level. Also, there are
differences in the shared culture and expectations of resource users;
more localized commons users tend to be more homogeneous and global
users more heterogeneous. This contributes to differences in the
possibility and time it takes for new learning about resource usage to
occur at the different levels. Moreover, global resource pools are less
likely to be relatively stable and the dynamics are less easily
understood. Many of the global commons are non-renewable on human time
scales. Thus, resource degradation is more likely to be the result of unintended consequences that are unforeseen, not immediately observable, or not easily understood. For example, the carbon dioxide emissions that drive climate change continue to do so for at least a millennium after they enter the atmosphere
and species extinctions last forever. Importantly, because there are
significant differences in the benefits, costs, and interests at the
global level, there are significant differences in externalities between more local resource uses and uses of global-level resources.
Several environmental protocols have been established (see List of international environmental agreements) as a type of international law,
"an intergovernmental document intended as legally binding with a
primary stated purpose of preventing or managing human impacts on
natural resources." International environmental protocols came to feature in environmental governance after trans-boundary environmental problems became widely perceived in the 1960s. Following the Stockholm Intergovernmental Conference in 1972, creation of international environmental agreements proliferated.
Due to the barriers already discussed, environmental protocols are not a
panacea for global commons issues. Often, they are slow to produce the
desired effects, tend to the lowest common denominator, and lack monitoring and enforcement. They also take an incremental approach to solutions where sustainable development principles suggest that environmental concerns should be mainstream political issues.
The global ocean
The global or world ocean, as the interconnected system of the Earth's oceanic (or marine) waters that comprise the bulk of the hydrosphere, is a classic global commons. It is divided into a number of principal oceanic areas that are delimited by the continents
and various oceanographic features. In turn, oceanic waters are
interspersed by many smaller seas, gulfs, and bays. Further, most
freshwater bodies ultimately empty into the ocean and are derived
through the Earth's water cycle from ocean waters. The Law of the Sea is a body of public international law governing relationships between nations in respect to navigational rights, mineral rights, and jurisdiction over coastal waters. Maritime law, also called Admiralty law, is a body of both domestic law governing maritime activities and private international law
governing the relationships between private entities which operate
vessels on the oceans. It deals with matters including marine commerce, marine navigation, shipping, sailors,
and the transportation of passengers and goods by sea. However, these
bodies of law do little to nothing to protect deep oceans from human
threats.
In addition to providing significant means of transportation, a large proportion of all life
on Earth exists in its ocean, which contains about 300 times the
habitable volume of terrestrial habitats. Specific marine habitats
include coral reefs, kelp forests, seagrass meadows, tidepools, muddy, sandy and rocky bottoms, and the open ocean (pelagic)
zone, where solid objects are rare and the surface of the water is the
only visible boundary. The organisms studied range from microscopic phytoplankton and zooplankton to huge cetaceans (whales) 30 meters (98 feet) in length.
At a fundamental level, marine life helps determine the very
nature of our planet. Marine life resources provide food (especially food fish),
medicines, and raw materials. It is also becoming understood that the
well-being of marine organisms and other organisms are linked in very
fundamental ways. The human body of knowledge regarding the relationship
between life in the sea and important cycles is rapidly growing, with
new discoveries being made nearly every day. These cycles include those
of matter (such as the carbon cycle) and of air (such as Earth's respiration, and movement of energy through ecosystems including the ocean). Marine organisms contribute significantly to the oxygen cycle, and are involved in the regulation of the Earth's climate. Shorelines are in part shaped and protected by marine life, and some marine organisms even help create new land.
The United Nations Environment Programme (UNEP)
has identified several areas of need in managing the global ocean:
strengthen national capacities for action, especially in developing
countries; improve fisheries management; reinforce cooperation in
semi-enclosed and regional seas; strengthen controls over ocean disposal
of hazardous and nuclear wastes; and advance the Law of the Sea.
Specific problems identified as in need of attention include rising sea levels; contamination by hazardours chemicals (including oil spills); microbiological contamination; ocean acidification; harmful algal blooms; and over-fishing and other overexploitation. Further, the Pew Charitable Trusts
Environmental Initiative program has identified a need for a worldwide
system of very large, highly protected marine reserves where fishing and
other extractive activities are prohibited.
Atmosphere
The atmosphere is a complex dynamic natural gaseous system that is
essential to support life on planet Earth. A primary concern for
management of the global atmosphere is air pollution, the introduction into the atmosphere of chemicals, particulates, or biological materials that cause discomfort, disease, or death to humans, damage other living organisms such as food crops, or damage the natural environment or built environment. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems.
Pollution of breathable air
is a central problem in the management of the global commons.
Pollutants can be in the form of solid particles, liquid droplets, or
gases and may be natural or man-made. Although controversial and
limited in scope by methods of enforcement, in several parts of the
world the polluter pays principle, which makes the party responsible for producing pollution responsible for paying for the damage done to the natural environment, is accepted. It has strong support in most Organisation for Economic Co-operation and Development (OECD) and European Community
(EC) countries. It is also known as extended producer responsibility
(EPR). EPR seeks to shift the responsibility dealing with waste from governments (and thus, taxpayers
and society at large) to the entities producing it. In effect, it
attempts to internalize the cost of waste disposal into the cost of the
product, theoretically resulting in producers improving the waste profile of their products, decreasing waste and increasing possibilities for reuse and recycling.
The 1979 Convention on Long-Range Transboundary Air Pollution,
or CLRTAP, is an early international effort to protect and gradually
reduce and prevent air pollution. It is implemented by the European
Monitoring and Evaluation Program (EMEP), directed by the United Nations Economic Commission for Europe (UNECE). The Montreal Protocol on Substances that Deplete the Ozone Layer, or Montreal Protocol (a protocol to the Vienna Convention for the Protection of the Ozone Layer), is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances believed to be responsible for ozone depletion. The treaty was opened for signature on 16 September 1987, and entered into force on 1 January 1989.
Global dimming is the gradual reduction in the amount of global direct irradiance at the Earth's
surface, which has been observed for several decades after the start of
systematic measurements in the 1950s. Global dimming is thought to have
been caused by an increase in particulates such as sulfate aerosols in the atmosphere due to human action. It has interfered with the hydrological cycle by reducing evaporation and may have reduced rainfall in some areas. Global dimming also creates a cooling effect that may have partially masked the effect of greenhouse gases on global warming.
Along with global warming, generalized climate change
is an ongoing global commons concern. Although global warming is now a
generally accepted scientific observation, the precise causes of global
warming are still a matter of research and debate. The Kyoto Protocol to the United Nations Framework Convention on Climate Change
(UNFCCC) is an international environmental treaty that sets binding
obligations on industrialised countries to reduce emissions of
greenhouse gases and prevent potentially harmful anthropogenic (i.e.,
human-induced) interference in the climate system. There are 192 parties to the convention, including 191 states and the European Union, but not all have ratified and implemented the protocol.
Polar regions
The eight Arctic nations Canada, Denmark ( Greenland and the Faroe Islands), Norway, the United States (Alaska), Sweden, Finland, Iceland, and Russia, are all members of the treaty organization, the Arctic Council, as are organizations representing six indigenous populations.
The Council operates on consensus basis, mostly dealing with
environmental treaties and not addressing boundary or resource disputes. Currently, the Antarctic Treaty and related agreements, collectively called the Antarctic Treaty System or ATS, regulate international relations with respect to Antarctica,
Earth's only continent without a native human population. The treaty,
entering into force in 1961 and currently having 50 signatory nations,
sets aside Antarctica as a scientific preserve, establishes freedom of
scientific investigation and bans military activity on that continent.
Climate change in the Arctic region is leading to widespread ecosystem restructuring.
The distribution of species is changing along with the structure of
food webs. Changes in ocean circulation appear responsible for the first
exchanges of zooplankton between the North Pacific and North Atlantic
regions in perhaps 800,000 years. These changes can allow the
transmission of diseases from subarctic animals to Arctic ones, and vice
versa, posing an additional threat to species already stressed by
habitat loss and other impacts. Where these changes lead is not yet
clear, but are likely to have far-reaching impacts on Arctic marine
ecosystems.
Climate models tend to reinforce that temperature trends due to
global warming will be much smaller in Antarctica than in the Arctic, but ongoing research may show otherwise.
Outer space
Management of outer space global commons has been contentious since the successful launch of the Sputnik satellite by the former Soviet Union on 4 October 1957. There is no clear boundary between Earth's atmosphere and space, although there are several standard boundary designations: one that deals with orbital velocity (the Kármán line),
one that depends on the velocity of charged particles in space, and
some that are determined by human factors such as the height at which
human blood begins to boil without a pressurized environment (the Armstrong line).
Space policy regarding a country's civilian space program, as well as its policy on both military use and commercial use of outer space, intersects with science policy, since national space programs often perform or fund research in space science, and also with defense policy, for applications such as spy satellites and anti-satellite weapons. It also encompasses government regulation of third-party activities such as commercial communications satellites and private spaceflight as well as the creation and application of space law and space advocacy organizations that exist to support the cause of space exploration.
The Outer Space Treaty
provides a basic framework for international space law. It covers the
legal use of outer space by nation states. The treaty states that outer
space is free for all nation states to explore and is not subject to
claims of national sovereignty. It also prohibits the deployment of nuclear weapons in outer space. The treaty was passed by the United Nations General Assembly
in 1963 and signed in 1967 by the USSR, the United States of America
and the United Kingdom. As of mid-year, 2013 the treaty has been
ratified by 102 states and signed by an additional 27 states.
Beginning in 1958, outer space has been the subject of multiple
resolutions by the United Nations General Assembly. Of these, more than
50 have concerned the international co-operation in the peaceful uses of
outer space and preventing an arms race in space. Four additional space law treaties have been negotiated and drafted by the UN's Committee on the Peaceful Uses of Outer Space. Still, there remain no legal prohibitions against deploying conventional weapons in space and anti-satellite weapons have been successfully tested by the US, USSR and China. The 1979 Moon Treaty
turned the jurisdiction of all heavenly bodies (including the orbits
around such bodies) over to the international community. However, this
treaty has not been ratified by any nation that currently practices
manned spaceflight.
In 1976 eight equatorial states (Ecuador, Colombia, Brazil, Congo, Zaire, Uganda, Kenya, and Indonesia) met in Bogotá,
Colombia to make the "Declaration of the First Meeting of Equatorial
Countries," also known as "the Bogotá Declaration", a claim to control
the segment of the geosynchronous orbital path corresponding to each
country. These claims are not internationally accepted.
The International Space Station programme is a joint project among five participating space agencies: NASA, the Russian Federal Space Agency (RSA), Japan Aerospace Exploration Agency (JAXA), European Space Agency (ESA), and Canadian Space Agency (CSA). National budget constraints led to the merger of three space station projects into the International Space Station. In 1993 the partially built components for a Soviet/Russian space station Mir-2, the proposed American Freedom, and the proposed European Columbus merged into this multinational program.
The ownership and use of the space station is established by
intergovernmental treaties and agreements. The ISS is arguably the most
expensive single item ever constructed, and may be one of the most significant instances of international cooperation in modern history.
According to the original Memorandum of Understanding between
NASA and the RSA, the International Space Station was intended to be a
laboratory, observatory and factory in space. It was also planned to
provide transportation, maintenance, and act as a staging base for
possible future missions to the Moon, Mars and asteroids. In the 2010
United States National Space Policy, it was given additional roles of
serving commercial, diplomatic and educational purposes.
Internet
As a global system of computers interconnected by telecommunication
technologies consisting of millions of private, public, academic,
business, and government resources, it is difficult to argue that the Internet is a global commons. These computing resources are largely privately owned and subject to private property law, although many are government owned and subject to public law. The World Wide Web, as a system of interlinked hypertext documents, either public domain (like Wikipedia itself) or subject to copyright law, is, at best, a mixed good.
The resultant virtual space or cyberspace, however, is often viewed as an electronic global commons that allows for as much or more freedom of expression as any public space. Access to those digital commons
and the actual freedom of expression allowed does vary widely by
geographical area. Management of the electronic global commons presents
as many issues as do other commons. In addition to issues related to inequity in access, issues such as net neutrality, Internet censorship, Internet privacy, and electronic surveillance arise.
