A Guide for the Perplexed is a short book by E. F. Schumacher, published in 1977. The title is a reference to Maimonides's The Guide for the Perplexed. Schumacher himself considered A Guide for the Perplexed to be his most important achievement, although he was better known for his 1973 environmental economics bestseller Small Is Beautiful, which made him a leading figure within the ecology movement. His daughter wrote that her father handed her the book on his deathbed, five days before he died and he told her "this is what my life has been leading to". As the Chicago Tribune wrote, "A Guide for the Perplexed is really a statement of the philosophical underpinnings that inform Small Is Beautiful".

Schumacher describes his book as being concerned with how humans live in the world. It is also a treatise on the nature and organisation of knowledge and is something of an attack on what Schumacher calls "materialistic scientism". Schumacher argues that the current philosophical "maps" that dominate western thought and science are both overly narrow and based on some false premises. However, this book is only in small part a critique.

Four Great Truths

Schumacher put forward what he considers to be the four great truths of philosophical map making:

  • The world is a hierarchical structure with at least four "levels of being".
  • The "Principle of Adequateness" determines human ability to accurately perceive the world.
  • Human learning relates to four "fields of knowledge".
  • The art of living requires an understanding of two types of problem: "convergent" and "divergent".

Critique of materialistic scientism

Schumacher was very much in favor of the scientific spirit, but felt that the dominant methodology within science, which he called materialistic scientism, was flawed and stood in the way of achieving knowledge in any other arena than inanimate nature. Schumacher believed that this flaw originated in the writings of Descartes and Francis Bacon, when modern science was first established.

He makes a distinction between the descriptive and instructional sciences. According to Schumacher the descriptive sciences are primarily concerned with what can be seen or otherwise experienced, e.g. botany and sociology, while the instructional sciences are concerned with how certain systems work and can be manipulated to produce certain results, e.g. biology and chemistry. Instructional science is primarily based on evidence gained from experimentation.

Materialistic scientism is based on the methodology of the instructional sciences, which developed to study and experiment with inanimate matter. According to Schumacher many philosophers of science fail to recognize the difference between descriptive and instructional science, or ascribe this difference to stages in the evolution of a specific science, which for these philosophers means that the instructional sciences are seen as being the most advanced variety of science.

He is particularly offended by the view that instructional science is the most advanced form of science, because for Schumacher, it is the study of the low hanging fruit of inanimate matter, or less metaphorically the study of the lowest and least complex level of being. As Schumacher sees it, knowledge gained about the higher levels of being, while far harder to get and far less certain, is all the more valuable.

He argues that applying the standards and procedures of instructional science to descriptive sciences is erroneous, because in the descriptive fields it is simply not possible to use the experimental techniques of instructional sciences. Experimentation is a very effective methodology when dealing with inanimate matter, but applying it to the living world is liable to destroy or damage living things and systems, and is therefore inappropriate.

He uses the term scientism because he argues that many people, including some philosophers of science, have misunderstood the theory behind instructional science and believe that it produces truth. But the instructional sciences are based on induction; and as David Hume famously points out induction is not the same as truth. Furthermore, according to Schumacher, instructional sciences are primarily concerned only with the parts of truth that are useful for manipulation, i.e. they focus on those instructions which are necessary to reliably produce certain results. But this does not mean that an alternative instruction set won't work, or indeed an alternative instruction set based on quite different principles. For Schumacher, instructional sciences therefore produce theories which are useful: pragmatic truths. By contrast, Schumacher argues that the descriptive sciences are interested in the truth in the wider sense of the word.

He argues that materialistic scientism follows a policy of leaving something out if it is in doubt. Consequently, the maps of western science fail to show large 'unorthodox' parts of both theory and practice of science and social science, and reveal a complete disregard for art and many other high level humanistic qualities. Such an approach, Schumacher argues, provides a grey, limited, utilitarian worldview without room for vitally important phenomena like beauty and meaning.

He observes that the mere mention of spirituality and spiritual phenomena in academic discussion is seen among scientists as a sign of 'mental deficiency' . Schumacher argues that where there is near total agreement a subject becomes effectively dead; it therefore is the subjects where there is doubt that deserve the most intense research. Schumacher believes in contrast to materialistic science that what is in doubt should be shown prominently, not hidden away or ignored.

His biggest complaint against materialistic scientism is that it rejects the validity of certain questions, which for Schumacher are actually the most important questions of all. Materialistic scientism rejects the idea of levels of being, but for Schumacher this leads to a one-sided view of nature. For Schumacher, you can learn much about humanity by studying from the perspective of minerals, plants and animals, because humans contain the lower levels of being. But that is not the full or even the most important part of the story, as he puts "...everything can be learned about him except that which makes us human."

Evolutionism

Schumacher first states that the evolutionist doctrine clearly sits in the descriptive sciences rather than instructive sciences. Schumacher accepts that evolution as a generalization within the descriptive science of biological change has been established beyond any doubt whatsoever. However, he considers the 'evolutionist doctrine' to be a very different matter. The evolutionist doctrine purports to prove and explain biological change in the same manner as the proof and explanation offered by the instructional sciences. Schumacher quotes the 1975 Encyclopædia Britannica as an example of this view "Darwin did two things: he showed that evolution was in fact contradicting scriptural legends of creation and that its cause, natural selection, was automatic leaving no room for divine guidance or design."

He considers the evolutionist doctrine to be a major philosophical and scientific error. Schumacher argues that the evolutionist doctrine starts with the perfectly reasonable explanation of change in living beings, and then jumps to using it as an explanation for the development of consciousness, self-awareness, language, social institutions and the origin of life itself. Schumacher points out that making this conceptual leap simply does not meet the standards of scientific rigor and the uncritical acceptance of this leap is, for Schumacher, completely unscientific.

Levels of being

For Schumacher one of science's major mistakes has been rejecting the traditional philosophical and religious view that the universe is a hierarchy of being. Schumacher makes a restatement of the traditional chain of being.

He agrees with the view that there are four kingdoms: Mineral, Plant, Animal, Human. He argues that there are critical differences of kind between each level of being. Between mineral and plant is the phenomenon of life. Schumacher says that although scientists say we should not use the phrase 'life energy', the difference still exists and has not been explained by science. Schumacher points out that though we can recognize life and destroy it, we can't create it. Schumacher notes that the 'life sciences' are 'extraordinary' because they hardly ever deal with life as such, and instead content themselves with analyzing the "physico-chemical body which is life's carrier." Schumacher goes on to say there is nothing in physics or chemistry to explain the phenomenon of life.

For Schumacher, a similar jump in level of being takes place between plant and animal, which is differentiated by the phenomenon of consciousness. We can recognize consciousness, not least because we can knock an animal unconscious, but also because animals exhibit at minimum primitive thought and intelligence.

The next level, according to Schumacher, is between Animal and Human, which are differentiated by the phenomenon of self-consciousness or self awareness. Self-consciousness is the reflective awareness of one's consciousness and thoughts.

Schumacher realizes that the terms—life, consciousness and self-consciousness—are subject to misinterpretation so he suggests that the differences can best be expressed as an equation which can be written thus:

  • "Mineral" = m
  • "Plant" = m + x
  • "Animal" = m + x + y
  • "Human" = m + x + y + z

In his theory, these three factors (x, y and z) represent ontological discontinuities. He argues that the differences can be likened to differences in dimension; and from one perspective it could be argued that only humans have 'real' existence insofar as they possess the three dimensions of life, consciousness and self-consciousness. Schumacher uses this perspective to contrast with the materialistic scientism view, which argues that what is 'real' is inanimate matter, denying the realness of life, consciousness and self-consciousness, despite the fact each individual can verify those phenomena from their own experience.

He directs our attention to the fact that science has generally avoided seriously discussing these discontinuities, because they present such difficulties for strictly materialistic science, and they largely remain mysteries.

Next he considers the animal model of humanity which has grown popular in science. Schumacher notes that within the humanities the distinction between consciousness and self consciousness is now seldom drawn. Consequently, people have become increasingly uncertain about whether there is any difference between animals and humans. Schumacher notes that a great deal of research about humans has been conducted by studying animals. Schumacher argues that this is analogous to studying physics in the hope of understanding life. Schumacher goes on to say that much can be learned about humanity by studying minerals, plants and animals because humans have inherited those levels of being: all, that is, "except that which makes him [sic] human."

Schumacher goes on to say that nothing is "more conducive to the brutalisation of the modern world" than calling humans the "naked ape". Schumacher argues that once people begin viewing humans as "animal machines" they soon begin treating them accordingly.

Schumacher argues that what defines humanity are our greatest achievements, not the common run of the mill things. He argues that human beings are open-ended because of self-awareness, which as distinct from life and consciousness has nothing mechanical or automatic about it. For Schumacher "the powers of self awareness are, essentially, a limitless potentiality rather than an actuality. They have to be developed and 'realized' by each human individual if one is to become truly human, that is to say, a person."

Progressions

Schumacher points out that there are a number of progressions that take place between the levels. The most striking he believes is the movement from passivity to activity, there is a change in the origination of movement between each level:

One consequence of this progression is that each level of being becomes increasingly unpredictable, and it is in this sense that humans can be said to have free will.

He notes increasing integration is a consequence of levels of being. A mineral can be subdivided and it remains of the same composition. Plants are more integrated; but sometimes parts of a plant can survive independently of the original plant. Animals are physically integrated; and so an appendage of an animal does not make another animal. However, while animals are highly integrated physically, they are not integrated in their consciousness. Humans, meanwhile, are not only physically integrated but have an integrated consciousness; however they are poorly integrated in terms of self-consciousness.

Another interesting progression, for him, is the change in the richness of the world at each level of being. A mineral has no world as such. A plant has some limited awareness of its immediate conditions. An animal, however, has a far more rich and complex world. Finally, humans have the most rich and complicated world of all.

Implications

For Schumacher, recognizing these different levels of being is vital, because the governing rules of each level are different, which has clear implications for the practice of science and the acquisition of knowledge. Schumacher denies the democratic principles of science. He argues that all humans can practice the study of the inanimate matter, because they are a higher level of being; but only the spiritually aware can know about self-consciousness and possibly higher levels. Schumacher states that "while the higher comprises and therefore in a sense understands the lower, no being can understand anything higher than themselves."

Schumacher argues that by removing the vertical dimension from the universe and the qualitative distinctions of "higher" and "lower" qualities which go with it, materialistic scientism can in the societal sphere only lead to moral relativism and utilitarianism. While in the personal sphere, answering the question "What do I do with my life?" leaves us with only two answers: selfishness and utilitarianism.

In contrast, he argues that appreciating the different levels of being provides a simple but clear morality. The traditional view, as Schumacher says, has always been that the proper goal of humanity is "...to move higher, to develop one's highest faculties, to gain knowledge of the higher and highest things, and, if possible, to "see God". If one moves lower, develops only one's lower faculties, which we share with the animals, then one makes oneself deeply unhappy, even to the point of despair." This is a view, Schumacher says, which is shared by all the major religions. Many things, Schumacher says, while true at a lower level, become absurd at a higher level, and vice versa.

Schumacher does not claim there is any scientific evidence for a level of being above self-consciousness, contenting himself with the observation that this has been the universal conviction of all major religions.

Adequateness

Schumacher explains that the bodily senses are adequate for perceiving inanimate matter; but we need 'intellectual' senses for other levels. Schumacher observes that science has shown that we perceive not only with the senses, but also with the mind. He illustrates this with the example of a complex scientific book; it means quite different things to an animal, illiterate man, educated man and scientist. Each person possesses different internal 'senses' which means they 'understand' the book in quite different manners.

He argues that the common view that "...the facts should speak for themselves" is problematic because it is not a simple matter to distinguish fact and theory or perception and interpretation. He quotes R. L. Gregory in Eye and Brain, "Perception is not determined simply by the stimulus pattern, rather it is a dynamic searching for the best interpretation of data." He argues that we 'see' not just with our eyes; but our mental equipment and "since this mental equipment varies greatly from person to person, there are inevitably many things which some people can 'see' while others cannot, or, to put it differently, for which some people are adequate while others are not."

For him, higher and more significant perceptive abilities are based on the ability to be critically aware of one's presuppositions. Schumacher writes "There is nothing more difficult than to be aware of one's thought. Everything can be seen directly except the eye through which we see. Every thought can be scrutinised directly except the thought by which we scrutinise. A special effort, an effort of self-awareness is needed — that almost impossible feat of thought recoiling upon itself: almost impossible but not quite. In fact, this is the power that makes man human and also capable of transcending his humanity."

He notes that for anyone who views the world through materialistic scientism this talk of higher perception is meaningless. For a scientist who believes in materialistic scientism, higher levels of being "simply do not exist, because his faith excludes the possibility of their existence."

He points out that materialistic science is principally based on the sense of sight and looks only at the external manifestation of things. Necessarily according to the principle of adequateness, materialistic science cannot know more than a limited part of nature. Schumacher argues that by restricting the modes of observation, a limited "objectivity" can be attained; but this is attained at the expense of knowledge of the object as a whole. Only the 'lowest' and most superficial aspects are accessible to objective scientific instruments.

He notes that science became "science for manipulation" following Descartes. Descartes promised humanity would become "masters and possessors of nature", a point of view first popularised by Francis Bacon. For Schumacher this was something of a wrong turn, because it meant the devaluation of "science for understanding" or wisdom. One of Schumacher's criticisms is that "science for manipulation" almost inevitably leads from the manipulation of nature to the manipulation of people. Schumacher argues that 'science for manipulation' is a valuable tool when subordinated for "science for understanding" or wisdom; but until then "science for manipulation" has become a danger to humanity.

Schumacher argues that if materialistic scientism grows to dominate science even further, then there will be three negative consequences:

  1. Quality of life will fall, because solutions of quantity are incapable of solving problems of quality.
  2. 'Science for understanding' will not develop, because the dominant paradigm will prevent it being treated as a serious subject.
  3. Problems will become insoluble, because the higher powers of man will atrophy through lack of use.

Schumacher argues that the ideal science would have a proper hierarchy of knowledge from pure knowledge for understanding at the top of the hierarchy to knowledge for manipulation at the bottom. At the level of knowledge for manipulation, the aims of prediction and control are appropriate. But as we deal with higher levels they become increasingly absurd. As he says "Human beings are highly predictable as physico-chemical systems, less predictable as living bodies, much less so as conscious beings and hardly at all as self aware persons."

The result of materialistic scientism is that humanity has become rich in means and poor in ends. Lacking a sense of higher values Western societies are left with pluralism, moral relativism and utilitarianism, and for Schumacher the inevitable result is chaos.

Four fields of knowledge

Schumacher identifies four fields of knowledge for the individual:

  1. I → inner
  2. I → other persons (inner)
  3. other persons → I
  4. I → the world

These four fields arise from combining two pairs: Myself and the World; and Outer Appearance and Inner Experience. He notes that humans only have direct access to fields one and four.

Field one is being aware of your feelings and thoughts and most closely correlates to self awareness. He argues this is fundamentally the study of attention. He differentiates between when your attention is captured by the item it focuses upon, which is when a human being functions much like a machine; and when a person consciously directs their attention according to their choosing. This for him is the difference between being lived and living.

Field two is being aware of what other people are thinking and feeling.

Despite these problems we do experience a 'meeting of minds' with other individuals at certain times. People are even able to ignore the words actually said, and say something like "I don't agree with what you are saying; but I do agree with what you mean." Schumacher argues that one of the reasons we can understand other people is through bodily experience, because so many bodily expressions, gestures and postures are part of our common human heritage.

Schumacher observes that the traditional answer to the study of field two has been "You can understand others to the extent you understand yourself." Schumacher points out that this a logical development of the principle of adequateness, how can you understand someone's pain unless you too have experienced pain?

Field three is understanding yourself as an objective phenomenon. Knowledge in field three requires you to be aware what other people think of you. Schumacher suggests that the most fruitful advice in this field can be gained by studying the Fourth Way concept of external considering.

Schumacher observes that relying on just field one knowledge makes you feel that you are the centre of the universe; while focusing on field three knowledge makes you feel that you are far more insignificant. Seeking self-knowledge via both fields provides more balanced and accurate self-knowledge.

Field four is the behaviourist study of the outside world. Science is highly active in this area of knowledge and many people believe it is the only field in which true knowledge can be gained. For Schumacher, applying the scientific approach is highly appropriate in this field.

Schumacher summarises his views about the four fields of knowledge as follows:

  • Only when all four fields of knowledge are cultivated can you have true unity of knowledge. Instruments and methodologies of study should be only applied to the appropriate field they are designed for.
  • Clarity of knowledge depends on relating the four fields of knowledge to the four levels of being.
  • The instructional sciences should confine their remit to field four, because it is only in the field of appearances that mathematical precision can be obtained. The descriptive sciences, however, are not behaving appropriately if they focus solely on appearances, and must delve in meaning and purpose or they will produce sterile results.
  • Self-knowledge can only be effectively pursued by balanced study of field one (self awareness) and field three (objective self-knowledge).
  • Study of field two (understanding other individuals) is dependent on first developing a powerful insight into field one (self awareness).

Two types of problems

Schumacher argues that there are two types of problems in the world: convergent and divergent. For him, discerning whether a problem is convergent or divergent is one of the arts of living.

Convergent problems are ones in which attempted solutions gradually converge on one solution or answer. An example of this has been the development of the bicycle. Early attempts at developing human-powered vehicles included three- and four-wheelers and involved wheels of different sizes. Modern bicycles look much the same nowadays.

Divergent problems are ones which do not converge on a single solution. A classic example he provides is that of education. Is discipline or freedom the best way to teach? Education researchers have debated this issue for thousand of years without converging on a solution.

He summarises by saying that convergent problems are those that are concerned with the non-living universe. While divergent problems are concerned with the universe of the living, and so there is always a degree of inner experience and freedom to contend with. According to Schumacher, the only solution to divergent problems is to transcend them, arguing that in education, for instance, that the real solution involves love or caring; love and discipline work effectively, but so does love and freedom.

Art

Schumacher in a digression from his main argument discusses the nature and importance of art. He notes that there is considerable confusion about the nature and meaning of art; but argues that this confusion dissipates when one considers art with relation to its effect on human beings. Most art fits into two categories. If art is designed to primarily affect our feelings then it is entertainment; while if art is primarily designed to affect our will then it is propaganda.

Great art is a multi-faceted phenomenon, which is not content to be merely propaganda or entertainment; but by appealing to people's higher intellectual and emotional faculties, it is designed to communicate truth. When entertainment and propaganda are transcended by, and subordinated to the communication of truth, art helps develop our higher faculties and that makes it great.

Tasks of humanity

Schumacher notes that within philosophy there is no field in more disarray than ethics. He argues that this is because most ethical debate sidesteps any "prior clarification of the purpose of human life on the earth." Schumacher believes that ethics is the study of divergent problems; which require transcendence by the individual, not a new type of ethics to be adopted by all.

He argues that there is an increasing recognition among individuals that many solutions to human problems must be made by individuals not by society, and cannot be solved by political solutions that rearrange the system. For Schumacher, the "modern attempt to live without religion has failed."

He says that the tasks of an individual can be summed up as follows:

  1. Learn from society and tradition.
  2. Interiorize this knowledge, learn to think for yourself and become self-directed.
  3. Grow beyond the narrow concerns of the ego.

Humanity, he says, in the larger sense must learn again to subordinate the sciences of manipulation to the sciences of wisdom; a theme he further develops in his book Small Is Beautiful.

Appropriate technology

From Wikipedia, the free encyclopedia

Appropriate technology is a movement (and its manifestations) encompassing technological choice and application that is small-scale, affordable by locals, decentralized, labor-intensive, energy-efficient, environmentally sound, and locally autonomous. It was originally articulated as intermediate technology by the economist Ernst Friedrich "Fritz" Schumacher in his work Small Is Beautiful. Both Schumacher and many modern-day proponents of appropriate technology also emphasize the technology as people-centered.

Appropriate technology has been used to address issues in a wide range of fields. Well-known examples of appropriate technology applications include: bike- and hand-powered water pumps (and other self-powered equipment), the universal nut sheller, self-contained solar lamps and streetlights, and passive solar building designs. Today appropriate technology is often developed using open source principles, which have led to open-source appropriate technology (OSAT) and thus many of the plans of the technology can be freely found on the Internet. OSAT has been proposed as a new model of enabling innovation for sustainable development. Free Software, including the MediaWiki software that runs this site, is licensed under the GNU GPL, or a similar license. It is this licensing model that has enabled the global wiki movement, not the licensing model of Open Source, which by itself is inadequate to prevent proprietary vendors from redistributing unfree versions of designs and software that they obtained gratis. Richard Stallman, the founder of the movement that created the GNU/Linux operating system, and it cultural heirs such as MediaWiki, has explained in detail the ethical and legal underpinnings of these projects as the Four Essential Freedoms of Free Software, and why this approach to appropriate technology is necessary for sustainable development.

Appropriate technology is most commonly discussed in its relationship to economic development and as an alternative to technology transfer of more capital-intensive technology from industrialized nations to developing countries. However, appropriate technology movements can be found in both developing and developed countries. In developed countries, the appropriate technology movement grew out of the energy crisis of the 1970s and focuses mainly on environmental and sustainability issues. Today the idea is multifaceted; in some contexts, appropriate technology can be described as the simplest level of technology that can achieve the intended purpose, whereas in others, it can refer to engineering that takes adequate consideration of social and environmental ramifications. The facets are connected through robustness and sustainable living.

Background

History

Predecessors

Indian ideological leader Mahatma Gandhi is often cited as the "father" of the appropriate technology movement. Though the concept had not been given a name, Gandhi advocated for small, local and predominantly village-based technology to help India's villages become self-reliant. He disagreed with the idea of technology that benefited a minority of people at the expense of the majority or that put people out of work to increase profit. In 1925 Gandhi founded the All-India Spinners Association and in 1935 he retired from politics to form the All-India Village Industries Association. Both organizations focused on village-based technology similar to the future appropriate technology movement.

China also implemented policies similar to appropriate technology during the reign of Mao Zedong and the following Cultural Revolution. During the Cultural Revolution, development policies based on the idea of "walking on two legs" advocated the development of both large-scale factories and small-scale village industries.

E. F. Schumacher

Despite these early examples, Dr. Ernst Friedrich "Fritz" Schumacher is credited as the founder of the appropriate technology movement. A well-known economist, Schumacher worked for the British National Coal Board for more than 20 years, where he blamed the size of the industry's operations for its uncaring response to the harm black-lung disease inflicted on the miners. However it was his work with developing countries, such as India and Burma, which helped Schumacher form the underlying principles of appropriate technology.

Schumacher first articulated the idea of "intermediate technology," now known as appropriate technology, in a 1962 report to the Indian Planning Commission in which he described India as long in labor and short in capital, calling for an "intermediate industrial technology" that harnessed India's labor surplus. Schumacher had been developing the idea of intermediate technology for several years prior to the Planning Commission report. In 1955, following a stint as an economic advisor to the government of Burma, he published the short paper "Economics in a Buddhist Country," his first known critique of the effects of Western economics on developing countries. In addition to Buddhism, Schumacher also credited his ideas to Gandhi.

Initially, Schumacher's ideas were rejected by both the Indian government and leading development economists. Spurred to action over concern the idea of intermediate technology would languish, Schumacher, George McRobie, Mansur Hoda and Julia Porter brought together a group of approximately 20 people to form the Intermediate Technology Development Group (ITDG) in May 1965. Later that year, a Schumacher article published in The Observer garnered significant attention and support for the group. In 1967, the group published the Tools for Progress: A Guide to Small-scale Equipment for Rural Development and sold 7,000 copies. ITDG also formed panels of experts and practitioners around specific technological needs (such as building construction, energy and water) to develop intermediate technologies to address those needs. At a conference hosted by the ITDG in 1968 the term "intermediate technology" was discarded in favor of the term "appropriate technology" used today. Intermediate technology had been criticized as suggesting the technology was inferior to advanced (or high) technology and not including the social and political factors included in the concept put forth by the proponents. In 1973, Schumacher described the concept of appropriate technology to a mass audience in his influential work Small Is Beautiful: A Study of Economics As If People Mattered.

Growing trend

The Universal Nut Sheller in use in Uganda, an example of appropriate technology

Between 1966 and 1975 the number of new appropriate technology organizations founded each year was three times greater than the previous nine years. There was also an increase in organizations focusing on applying appropriate technology to the problems of industrialized nations, particularly issues related to energy and the environment. In 1977, the OECD identified in its Appropriate Technology Directory 680 organizations involved in the development and promotion of appropriate technology. By 1980, this number had grown to more than 1,000. International agencies and government departments were also emerging as major innovators in appropriate technology, indicating its progression from a small movement fighting against the established norms to a legitimate technological choice supported by the establishment. For example, the Inter-American Development Bank created a Committee for the Application of Intermediate Technology in 1976 and the World Health Organization established the Appropriate Technology for Health Program in 1977.

Appropriate technology was also increasingly applied in developed countries. For example, the energy crisis of the mid-1970s led to the creation of the National Center for Appropriate Technology (NCAT) in 1977 with an initial appropriation of 3 million dollars from the U.S. Congress. The Center sponsored appropriate technology demonstrations to "help low-income communities find better ways to do things that will improve the quality of life, and that will be doable with the skills and resources at hand." However, by 1981 the NCAT's funding agency, Community Services Administration, had been abolished. For several decades NCAT worked with the US departments of Energy and Agriculture on contract to develop appropriate technology programs. Since 2005, NCAT's informational web site is no longer funded by the US government.

Decline

In more recent years, the appropriate technology movement has continued to decline in prominence. Germany's German Appropriate Technology Exchange (GATE) and Holland's Technology Transfer for Development (TOOL) are examples of organizations no longer in operation. Recently, a study looked at the continued barriers to AT deployment despite the relatively low cost of transferring information in the internet age. The barriers have been identified as: AT seen as inferior or "poor person's" technology, technical transferability and robustness of AT, insufficient funding, weak institutional support, and the challenges of distance and time in tackling rural poverty.

A more free market-centric view has also begun to dominate the field. For example, Paul Polak, founder of International Development Enterprises (an organization that designs and manufactures products that follow the ideals of appropriate technology), declared appropriate technology dead in a 2010 blog post.

Polak argues the "design for the other 90 percent" movement has replaced appropriate technology. Growing out of the appropriate technology movement, designing for the other 90 percent advocates the creation of low-cost solutions for the 5.8 billion of the world's 6.8 billion population "who have little or no access to most of the products and services many of us take for granted."

Many of the ideas integral to appropriate technology can now be found in the increasingly popular "sustainable development" movement, which among many tenets advocates technological choice that meets human needs while preserving the environment for future generations. In 1983, the OECD published the results of an extensive survey of appropriate technology organizations titled, The World of Appropriate Technology, in which it defined appropriate technology as characterized by "low investment cost per work-place, low capital investment per unit of output, organizational simplicity, high adaptability to a particular social or cultural environment, sparing use of natural resources, low cost of final product or high potential for employment." Today, the OECD web site redirects from the "Glossary of Statistical Terms" entry on "appropriate technology" to "environmentally sound technologies." The United Nations' "Index to Economic and Social Development" also redirects from the "appropriate technology" entry to "sustainable development."

Potential resurgence

Despite the decline, several appropriate technology organizations are still in existence, including the ITDG which became Practical Action after a name change in 2005. Skat (Schweizerische Kontaktstelle für Angepasste Technology) adapted by becoming a private consultancy in 1998, though some Intermediate Technology activities are continued by Skat Foundation through the Rural Water Supply Network (RWSN). Another actor still very active is the charity CEAS (Centre Ecologique Albert Schweitzer). A pioneer in food transformation and solar heaters, it offers vocational training in West Africa and Madagascar. There is also currently a notable resurgence as viewed by the number of groups adopting open source appropriate technology (OSAT) because of the enabling technology of the Internet. These OSAT groups include: Akvo Foundation, Appropedia, The Appropriate Technology Collaborative, Catalytic Communities, Centre for Alternative Technology, Center For Development Alternatives, Engineers Without Borders, Open Source Ecology, Practical Action, and Village Earth. Most recently ASME, Engineers Without Borders (USA) and the IEEE have joined together to produce Engineering for Change, which facilitates the development of affordable, locally appropriate and sustainable solutions to the most pressing humanitarian challenges.

Terminology

Appropriate technology frequently serves as an umbrella term for a variety names for this type of technology. Frequently these terms are used interchangeably; however, the use of one term over another can indicate the specific focus, bias or agenda of the technological choice in question. Though the original name for the concept now known as appropriate technology, "intermediate technology" is now often considered a subset of appropriate technology that focuses on technology that is more productive than "inefficient" traditional technologies, but less costly than the technology of industrialized societies. Other types of technology under the appropriate technology umbrella include:

  • Capital-saving technology
  • Labor-intensive technology
  • Alternate technology
  • Self-help technology
  • Village-level technology
  • Community technology
  • Progressive technology
  • Indigenous technology
  • People's technology
  • Light-engineering technology
  • Adaptive technology
  • Light-capital technology
  • Soft technology

A variety of competing definitions exist in academic literature and organization and government policy papers for each of these terms. However, the general consensus is appropriate technology encompasses the ideas represented by the above list. Furthermore, the use of one term over another in referring to an appropriate technology can indicate ideological bias or emphasis on particular economic or social variables. Some terms inherently emphasize the importance of increased employment and labor utilization (such as labor-intensive or capital-saving technology), while others may emphasize the importance of human development (such as self-help and people's technology).

It is also possible to distinguish between hard and soft technologies. According to Dr. Maurice Albertson and Audrey Faulkner, appropriate hard technology is "engineering techniques, physical structures, and machinery that meet a need defined by a community, and utilize the material at hand or readily available. It can be built, operated and maintained by the local people with very limited outside assistance (e.g., technical, material, or financial). it is usually related to an economic goal."

Albertson and Faulkner consider appropriate soft technology as technology that deals with "the social structures, human interactive processes, and motivation techniques. It is the structure and process for social participation and action by individuals and groups in analyzing situations, making choices and engaging in choice-implementing behaviors that bring about change."

Practitioners

Some of the well known practitioners of the appropriate technology sector include: B.V. Doshi, Buckminster Fuller, William Moyer (1933–2002), Amory Lovins, Sanoussi Diakité, Albert Bates, Victor Papanek, Giorgio Ceragioli (1930–2008), Frithjof Bergmann, Arne Næss, (1912–2009), Mansur Hoda, and Laurie Baker.

Development

Schumacher's initial concept of intermediate technology was created as a critique of the currently prevailing development strategies which focused on maximizing aggregate economic growth through increases to overall measurements of a country's economy, such as gross domestic product (GDP). Developed countries became aware of the situation of developing countries during and in the years following World War II. Based on the continuing rise in income levels in Western countries since the Industrial Revolution, developed countries embarked on a campaign of massive transfers of capital and technology to developing countries in order to force a rapid industrialization intended to result in an economic "take-off" in the developing countries.

However, by the late 1960s it was becoming clear this development method had not worked as expected and a growing number of development experts and national policy makers were recognizing it as a potential cause of increasing poverty and income inequality in developing countries. In many countries, this influx of technology had increased the overall economic capacity of the country. However, it had created a dual or two-tiered economy with pronounced division between the classes. The foreign technology imports were only benefiting a small minority of urban elites. This was also increasing urbanization with the rural poor moving to urban cities in hope of more financial opportunities. The increased strain on urban infrastructures and public services led to "increasing squalor, severe impacts on public health and distortions in the social structure."

Appropriate technology was meant to address four problems: extreme poverty, starvation, unemployment and urban migration. Schumacher saw the main purpose for economic development programs was the eradication of extreme poverty and he saw a clear connection between mass unemployment and extreme poverty. Schumacher sought to shift development efforts from a bias towards urban areas and on increasing the output per laborer to focusing on rural areas (where a majority of the population still lived) and on increasing employment.

In developed countries

The term appropriate technology is also used in developed nations to describe the use of technology and engineering that result in less negative impacts on the environment and society, i.e., technology should be both environmentally sustainable and socially appropriate. E. F. Schumacher asserts that such technology, described in the book Small Is Beautiful, tends to promote values such as health, beauty and permanence, in that order.

Often the type of appropriate technology that is used in developed countries is "appropriate and sustainable technology" (AST), appropriate technology that, besides being functional and relatively cheap (though often more expensive than true AT), is durable and employs renewable resources. AT does not include this (see Sustainable design).

Applications

Building and construction

In order to increase the efficiency of a great number of city services (efficient water provisioning, efficient electricity provisioning, easy traffic flow, water drainage, decreased spread of disease with epidemics, etc.), the city itself must first be built correctly. In the developing world, many cities are expanding rapidly and new ones are being built. Looking into the cities design in advance is a must for every developing nation.

The local context must be considered as, for example, mudbrick may not be durable in a high rainfall area (although a large roof overhang and cement stabilisation can be used to correct for this), and, if the materials are not readily available, the method may be inappropriate. Other forms of natural building may be considered appropriate technology, though in many cases the emphasis is on sustainability and self-sufficiency rather than affordability or suitability. As such, many buildings are also built to function as autonomous buildings (e.g., earthships). One example of an organisation that applies appropriate earthbuilding techniques would be Builders Without Borders.

The building structure must also be considered. Cost-effectiveness is an important issue in projects based around appropriate technology, and one of the most efficient designs herein is the public housing approach. This approach lets everyone have their own sleeping/recreation space, yet incorporate communal spaces such as mess halls, latrines, and public showers.

In addition, to decrease costs of operation (heating, cooling, etc.) techniques as Earth sheltering and Trombe walls are often incorporated.

Organizations as Architecture for Humanity also follows principles consistent with appropriate technology, aiming to serve the needs of poor and disaster-affected people.

  • Natural ventilation can be created by providing vents in the upper level of a building to allow warm air to rise by convection and escape to the outside, while cooler air is drawn in through vents at the lower level.
  • Electrical powered fans (e.g., ceiling fans) allow efficient cooling, at a far lower electricity consumption as airconditioning systems.
  • A solar chimney often referred to as thermal chimney improves this natural ventilation by using convection of air heated by passive solar energy. To further maximize the cooling effect, the incoming air may be led through underground ducts before it is allowed to enter the building.
  • A windcatcher (Badgir; بادگیر) is a traditional Persian architectural device used for many centuries to create natural ventilation in buildings. It is not known who first invented the windcatcher, but it still can be seen in many countries today. Windcatchers come in various designs, such as the uni-directional, bi-directional, and multi-directional.
  • A passive down-draft cooltower may be used in a hot, arid climate to provide a sustainable way to provide air conditioning. Water is allowed to evaporate at the top of a tower, either by using evaporative cooling pads or by spraying water. Evaporation cools the incoming air, causing a downdraft of cool air that will bring down the temperature inside the building.

Agriculture

Appropriate technology has been applied extensively to improve agricultural production in developing countries. In the United States, the National Center for Appropriate Technology operates ATTRA (attra.ncat.org), a national sustainable agriculture assistance program.

Water and sanitation

Water

Hand-operated, reciprocating, positive displacement, water pump in Košice-Tahanovce, Slovakia (walking beam pump).

As of 2006, waterborne diseases are estimated to cause 1.8 million deaths each year while about 1.1 billion people lack proper drinking water.

Water generally needs treatment before use, depending on the source and the intended use (with high standards required for drinking water). The quality of water from household connections and community water points in low-income countries is not reliably safe for direct human consumption. Water extracted directly from surface waters and open hand-dug shallow wells nearly always requires treatment.

Appropriate technology options in water treatment include both community-scale and household-scale point-of-use (POU) designs.

The most reliable way to kill microbial pathogenic agents is to heat water to a rolling boil. Other techniques, such as varying forms of filtration, chemical disinfection, and exposure to ultraviolet radiation (including solar UV) have been demonstrated in an array of randomized control trials to significantly reduce levels of waterborne disease among users in low-income countries.

Over the past decade, an increasing number of field-based studies have been undertaken to determine the success of POU measures in reducing waterborne disease. The ability of POU options to reduce disease is a function of both their ability to remove microbial pathogens if properly applied and such social factors as ease of use and cultural appropriateness. Technologies may generate more (or less) health benefit than their lab-based microbial removal performance would suggest.

The current priority of the proponents of POU treatment is to reach large numbers of low-income households on a sustainable basis. Few POU measures have reached significant scale thus far, but efforts to promote and commercially distribute these products to the world's poor have only been under way for a few years.

On the other hand, small-scale water treatment is reaching increasing fractions of the population in low-income countries, particularly in South and Southeast Asia, in the form of water treatment kiosks (also known as water refill stations or packaged water producers). While quality control and quality assurance in such locations may be variable, sophisticated technology (such as multi-stage particle filtration, UV irradiation, ozonation, and membrane filtration) is applied with increasing frequency. Such microenterprises are able to vend water at extremely low prices, with increasing government regulation. Initial assessments of vended water quality are encouraging.

Whether applied at the household or community level, some examples of specific treatment processes include:

Some appropriate technology water supply measures include:

  • Deep wells with submersible pumps in areas where the groundwater (aquifers) are located at depths >10 m.
  • Shallow wells with lined walls and covers.
  • Rainwater harvesting systems with an appropriate method of storage, especially in areas with significant dry seasons.
  • Fog collection, which is suitable for areas which experience fog even when there is little rain.
  • Air wells, a structure or device designed to promote the condensation of atmospheric moisture.
  • Handpumps and treadle pumps are generally only an option in areas is located at a relatively shallow depth (e.g., 10 m). The Flexi-Pipe Pump is a notable exception to this (up to 25 meters). For deeper aquifers (<10 m), The Rope pump and submersible pumps placed inside a well can be used. Treadle pumps for household irrigation are now being distributed on a widespread basis in developing countries. The principle of Village Level Operation and Maintenance is important with handpumps, but may be difficult in application.
  • Condensation bags and condensation pits can be an appropriate technology to get water, yet yields are low and are (for the amount of water obtained), labour-intensive. Still, it may be a good (very cheap) solution for certain desperate communities.
  • The hippo water roller and Q-drum allow more water to be carried, with less effort and could thus be a good alternative for ethnic communities who do not wish to give up water gathering from remote locations, assuming low topographic relief.
  • The roundabout playpump, developed and used in southern Africa, harnesses the energy of children at play to pump water.

Sanitation

Poor sanitation is a major issue for a large proportion of the human population, with about 2.5 billion people lacking even the most basic forms of sanitation and more than a billion people worldwide practising open defecation in 2015 according to the Joint Monitoring Programme for Water Supply and Sanitation of the United Nations.

The ideas of appropriate technology influenced the provision of sanitation systems for many years. However, since about the early 2000s there has been a departure from a focus on simplistic 'one-size-fits-all' sanitation systems. As conditions vary, sanitation systems also need to vary to meet the needs of the users and other stakeholders.

Technologies for sanitation provision, such as toilets, are important but only one piece of the puzzle. Sanitation needs to be regarded as a system that includes technical and non-technical aspects, such as behavior change and management as well as political aspects – the enabling environment. The overall aim should be to achieve a sustainable sanitation system. One option of achieving that aim can be the ecological sanitation approach which focuses on safe reuse of excreta.

It is impossible to name all possible sanitation technologies that may fall under the category of "appropriate technologies" but some common systems which might be considered to be "appropriate" include:

  • Dry toilets as they save on flushing water and may allow the nutrients of the excreta to be reused in agriculture (e.g., for fertilising crops). Two examples of dry toilets are composting toilets and urine-diverting dry toilets.
  • Constructed wetlands which can treat wastewater and greywater and require only little electrical power.
  • The SanPlat is a simple plate that can be used to cover the hole in the ground of pit latrines making them potentially more easy to clean and maintain.
  • The Arborloo which is a very simple low-cost type of composting toilet suitable for rural areas.

Energy generation and uses

The term soft energy technology was coined by Amory Lovins to describe "appropriate" renewable energy. "Appropriate" energy technologies are especially suitable for isolated and/or small scale energy needs. Electricity can be provided from:

Some intermediate technologies include:

  • Bioalcohols as bioethanol, biomethanol and biobutanol. The first two require minor modifications to allow them to be used in conventional gasoline engines. The third requires no modifications at all.
  • Vegetable oils which can be used only in internal combustion (Diesel) engines. Biofuels are locally available in many developing countries and can be cheaper than fossil fuels.
  • Anaerobic digestion power plants
  • Biogas is another potential source of energy, particularly where there is an abundant supply of waste organic matter. A generator (running on biofuels) can be run more efficiently if combined with batteries and an inverter; this adds significantly to capital cost but reduces running cost, and can potentially make this a much cheaper option than the solar, wind and micro-hydro options.
  • Dry animal dung fuel can also be used.
  • Biochar is another similar energy source which can be obtained through charring of certain types of organic material (e.g., hazelnut shells, bamboo, chicken manure, etc.) in a pyrolysis unit. A similar energy source is terra preta nova.
  • Chemurgy

Finally, urine can also be used as a basis to generate hydrogen (which is an energy carrier). Using urine, hydrogen production is 332% more energy efficient than using water.

Electricity distribution could be improved so to make use of a more structured electricity line arrangement and universal AC power plugs and sockets (e.g., the CEE 7/7 plug). In addition, a universal system of electricity provisioning (e.g., universal voltage, frequency, ampère; e.g., 230 V with 50 Hz), as well as perhaps a better mains power system (e.g., through the use of special systems as perfected single-wire earth returns; e.g., Tunisia's MALT-system, which features low costs and easy placement)

Electricity storage (which is required for autonomous energy systems) can be provided through appropriate technology solutions as deep-cycle and car-batteries (intermediate technology), long duration flywheels, electrochemical capacitors, compressed air energy storage (CAES), liquid nitrogen and pumped hydro. Many solutions for the developing world are sold as a single package, containing a (micro) electricity generation power plant and energy storage. Such packages are called remote-area power supply

LED Lamp with GU10 twist lock fitting, intended to replace halogen reflector lamps.
  • White LEDs and a source of renewable energy (such as solar cells) are used by the Light Up the World Foundation to provide lighting to poor people in remote areas, and provide significant benefits compared to the kerosene lamps which they replace. Certain other companies as Powerplus also have LED-flashlights with imbedded solar cells.
  • Organic LEDs made by roll-to-roll production are another source of cheap light that will be commercially available at low cost by 2015.
  • Compact fluorescent lamps (as well as regular fluorescent lamps and LED-lightbulbs) can also be used as appropriate technology. Although they are less environmentally friendly than LED-lights, they are cheaper and still feature relative high efficiency (compared to incandescent lamps).
  • The Safe bottle lamp is a safer kerosene lamp designed in Sri Lanka. Lamps as these allow relative long, mobile, lighting. The safety comes from a secure screw-on metal lid, and two flat sides which prevent it from rolling if knocked over. An alternative to fuel or oil-based lanterns is the Uday lantern, developed by Philips as part of its Lighting Africa project (sponsored by the World Bank Group).
  • The Faraday flashlight is an LED flashlight which operates on a capacitor. Recharging can be done by manual winching or by shaking, hereby avoiding the need of any supplementary electrical system.
  • HID-lamps finally can be used for lighting operations where regular LED-lighting or other lamps will not suffice. Examples are car headlights. Due to their high efficiency, they are quite environmental, yet costly, and they still require polluting materials in their production process.

Transportation

A man uses a bicycle to cargo goods in Ouagadougou, Burkina Faso (2007)

Human powered-vehicles include the bicycle (and the future bamboo bicycle), which provides general-purpose transportation at lower costs compared to motorized vehicles, and many advantages over walking, and the whirlwind wheelchair, which provides mobility for disabled people who cannot afford the expensive wheelchairs used in developed countries. Animal powered vehicles/transport may also be another appropriate technology. Certain zero-emissions vehicles may be considered appropriate transportation technology, including compressed air cars, liquid nitrogen and hydrogen-powered vehicles. Also, vehicles with internal combustion engines may be converted to hydrogen or oxyhydrogen combustion.

Bicycles can also be applied to commercial transport of goods to and from remote areas. An example of this is Karaba, a free-trade coffee co-op in Rwanda, which uses 400 modified bicycles to carry hundreds of pounds of coffee beans for processing. Other projects for developing countries include the redesign of cycle rickshaws to convert them to electric power. However recent reports suggest that these rickshaws are not plying on the roads.

Health care

According to the Global Health Council, rather than the use of professionally schooled doctors, the training of villagers to remedy most maladies in towns in the developing world is most appropriate. Trained villagers are able to eliminate 80% of the health problems. Small (low-cost) hospitals – based on the model of the Jamkhed hospital – can remedy another 15%, while only 5% will need to go to a larger (more expensive) hospital.

  • Before being able to determine the cause of the disease or malady, accurate diagnosis is required. This may be done manually (through observation, inquiries) and by specialized tools.
  • A phase-change incubator, developed in the late 1990s, is a low-cost way for health workers to incubate microbial samples.
  • Birth control is also seen as an appropriate technology, especially now, because of increasing population numbers (overpopulating certain areas), increasing food prices and poverty. It has been proposed to a certain degree by PATH (program for appropriate technology in health).
  • Jaipur leg was developed by Dr. P. K. Sethi and Masterji Ram Chander in 1968 as an inexpensive prosthetic leg for victims of landmine explosions.
  • The Leveraged Freedom Chair is a low-cost wheelchair designed specifically for rough terrain
  • Natural cleaning products can be used for personal hygiene and cleaning of clothing and eating utensils; in order to decrease illnesses/maladies (as they eliminate a great amount of pathogens).

Note that many Appropriate Technologies benefit public health, in particular by providing sanitation and safe drinking water. Refrigeration may also provide a health benefit. (These are discussed in the following paragraphs.) This was too found at the Comprehensive Rural Health Project and the Women Health Volunteers projects in countries as Iran, Iraq and Nepal.

Food preparation and storage

Some proven intensive, low-effort food-production systems include urban gardening (indoors and outdoors). Indoor cultivation may be set up using hydroponics with Grow lights, while outdoor cultivation may be done using permaculture, forest gardening, no-till farming, Do Nothing Farming, etc. In order to better control the irrigation outdoors, special irrigation systems may be created as well (although this increases costs, and may again open the door to cultivating non-indigenous plants; something which is best avoided). One such system for the developing world is discussed here.

Crop production tools are best kept simple (reduces operating difficulty, cost, replacement difficulties and pollution, when compared to motorized equipment). Tools can include scythes, animal-pulled plows (although no-till farming should be preferred), dibbers, wheeled augers (for planting large trees), kirpis, hoes, etc.

Greenhouses are also sometimes included (see Earthship Biotincture). Sometimes they are also fitted with irrigation systems, and/or heat sink-systems which can respectively irrigate the plants or help to store energy from the sun and redistribute it at night (when the greenhouse starts to cool down).

According to proponents, Appropriate Technologies can greatly reduce the labor required to prepare food, compared to traditional methods, while being much simpler and cheaper than the processing used in Western countries. This reflects E.F. Schumacher's concept of "intermediate technology," i.e., technology which is significantly more effective and expensive than traditional methods, but still an order of magnitude (10 times) cheaper than developed world technology. Key examples are:

  • the Malian peanut sheller
  • the fonio husking machine
  • the screenless hammer mill
  • the ISF corn mill
  • the ISF rice huller
  • all other types of electrical or hand-operated kitchen equipment (grinders, cutters, etc.) Special multifunctional kitchen robots that are able to perform several functions (e.g., grinding, cutting, and even vacuum cleaning and polishing) are able to reduce costs even more. An example of these devices was the (now discontinued) Piccolo household appliance from Hammelmann Werke (previously based in Bad Kissingen). It was equipped with a flexible axis, allowing a variety of aids to be screwed on.
In Ghana, Zouzugu villagers use solar cookers for preparing their meals
  • Solar cookers are appropriate to some settings, depending on climate and cooking style. They are emission-less and very low-cost. Hybrid variants also exist that incorporate a second heating source such as electrical heating or wood-based.
  • Hot plates are 100% electrical, fairly low cost (around €20) and are mobile. They do however require an electrical system to be present in the area of operation.
  • Rocket stoves and certain other woodstoves (e.g., Philips Woodstove) improve fuel efficiency, and reduce harmful indoor air pollution. The stoves however still make use of wood. However, briquette makers can now turn organic waste into fuel, saving money and/or collection time, and preserving forests.
  • Solar, special Einstein refrigerators and thermal mass refrigerators reduce the amount of electricity required. Also, solar and special Einstein refrigerators do not use haloalkanes (which play a key role in ozone depletion), but use heat pumps or mirrors instead. Solar refrigerators have been built for developing nations by Sopology.
  • The pot-in-pot refrigerator is an African invention which keeps things cool without electricity. It provides a way to keep food and produce fresh for much longer than would otherwise be possible. This can be a great benefit to the families who use the device. For example, it is claimed that girls who had to regularly sell fresh produce in the market can now go to school instead, as there is less urgency to sell the produce before it loses freshness.

Information and communication technologies

Netbooks such as the Asus Eee PC accommodate low-cost information sharing and communication
  • The OLPC XO, Simputer, Asus Eee PC, and other low-cost computers are computers aimed at developing countries. Besides the low price, other characteristics include resistance to dust, reliability and use of the target language.
  • Eldis OnDisc and The Appropriate Technology Library are projects that use CDs and DVDs to give access to development information in areas without reliable and affordable internet access.
  • The wind-up radio and the computer and communication system planned by the Jhai Foundation are independent from power supply.
  • There is also GrameenPhone, which fused mobile telephony with Grameen Bank's microfinance program to give Bangladeshi villagers access to communication.
  • Mobile telephony is appropriate technology for many developing countries, as it greatly reduces the infrastructure required to achieve widespread coverage. However, mobile phone network may not always be available (it depends on the location) and may not always provide both voice and data services.
  • Loband, a website developed by Aptivate, strips all the photographic and other bandwidth-intensive content from webpages and renders them as simple text, while otherwise allowing one to browse them normally. The site greatly increases the speed of browsing, and is appropriate for use on low bandwidth connections as generally available in much of the developing world.
  • An increasing number of activists provide free or very inexpensive web and email services using cooperative computer networks that run wireless ad hoc networks. Network service is provided by a cooperative of neighbors, each operating a router as a household appliance. These minimize wired infrastructure, and its costs and vulnerabilities. Private Internet protocol networks set up in this way can operate without the use of a commercial provider.
  • Rural electrical grids can be wired with "optical phase cable", in which one or more of the steel armor wires are replaced with steel tubes containing fiber optics.
  • Satellite Internet access can provide high speed connectivity to remote locations, however these are significantly more expensive than wire-based or terrestrial wireless systems. Wimax and forms of packet radio can also be used. Depending on the speed and latency of these networks they may be capable of relaying VoIP traffic, negating the need for separate telephony services. Finally, the Internet Radio Linking Project provides potential for blending older (cheap) local radio broadcasting with the increased range of the internet.
  • Satellite-based telephone systems can also be used, as either fixed installations or portable handsets and can be integrated into a PABX or local IP-based network.

Finance

Through financial systems envisioned especially for the very poor/developed world, many companies have been able to get started with only limited capital. Often banks lend the money to people wishing to start a business (such as with microfinance). In other systems, people for a Rotating Savings and Credit Association or ROSCA to purchase costly material together (such as Tontines and Susu accounts). Organisations, communities, cities or individuals can provide loans to other communities/cities (such as with the approach followed by Kiva, World Vision Microloans, MicroPlace and LETS). Finally, in certain communities (usually isolated communities such as small islands or oases) everything of value is shared. This is called gift economy.

Determining a sustainable approach

Features such as low cost, low usage of fossil fuels and use of locally available resources can give some advantages in terms of sustainability. For that reason, these technologies are sometimes used and promoted by advocates of sustainability and alternative technology.

Besides using natural, locally available resources (e.g., wood or adobe), waste materials imported from cities using conventional (and inefficient) waste management may be gathered and re-used to build a sustainable living environment. Use of these cities' waste material allows the gathering of a huge amount of building material at a low cost. When obtained, the materials may be recycled over and over in the own city/community, using the cradle to cradle design method. Locations where waste can be found include landfills, junkyards, on water surfaces and anywhere around towns or near highways. Organic waste that can be reused to fertilise plants can be found in sewages. Also, town districts and other places (e.g., cemeteries) that are subject of undergoing renovation or removal can be used for gathering materials as stone, concrete, or potassium.
