Tragedy of the commons

The tragedy of the commons is a situation in a shared-resource system where individual users, acting independently according to their own self-interest, behave contrary to the common good of all users by depleting or spoiling the shared resource through their collective action. The theory originated in an essay written in 1833 by the British economist William Forster Lloyd, who used a hypothetical example of the effects of unregulated grazing on common land in Great Britain and Ireland; the concept became known as the "tragedy of the commons" over a century due to an article written by American biologist and philosopher Garrett Hardin in 1968. In this modern economic context, "commons" is taken to mean any shared and unregulated resource such as atmosphere, rivers, fish stocks and highways, or an office refrigerator; the term is used in environmental science. The "tragedy of the commons" is cited in connection with sustainable development, meshing economic growth and environmental protection, as well as in the debate over global warming.

It has been used in analyzing behavior in the fields of economics, evolutionary psychology, game theory, politics and sociology. Although common resource systems have been known to collapse due to overuse, many examples have existed and still do exist where members of a community with access to a common resource co-operate or regulate to exploit those resources prudently without collapse. Elinor Ostrom was awarded the 2009 Nobel Prize in Economics for demonstrating this concept in her book Governing the Commons, which included examples of how local communities were able to do this without top-down regulations or privatization. In 1833, the English economist William Forster Lloyd published a pamphlet which included a hypothetical example of over-use of a common resource; this was the situation of cattle herders sharing a common parcel of land on which they were each entitled to let their cows graze, as was the custom in English villages. He postulated that if a herder put more than his allotted number of cattle on the common, overgrazing could result.

For each additional animal, a herder could receive additional benefits, while the whole group shared the resulting damage to the commons. If all herders made this individually rational economic decision, the common could be depleted or destroyed, to the detriment of all. In 1968, ecologist Garrett Hardin explored this social dilemma in his article "The Tragedy of the Commons", published in the journal Science; the essay derived its title from the pamphlet by Lloyd, which he cites, on the over-grazing of common land. Hardin discussed problems that cannot be solved by technical means, as distinct from those with solutions that require "a change only in the techniques of the natural sciences, demanding little or nothing in the way of change in human values or ideas of morality". Hardin focused on human population growth, the use of the Earth's natural resources, the welfare state. Hardin argued that if individuals relied on themselves alone, not on the relationship of society and man the number of children had by each family would not be of public concern.

Parents breeding excessively would leave fewer descendants because they would be unable to provide for each child adequately. Such negative feedback is found in the animal kingdom. Hardin said that if the children of improvident parents starved to death, if overbreeding was its own punishment there would be no public interest in controlling the breeding of families. Hardin blamed the welfare state for allowing the tragedy of the commons. In his article, Hardin lamented the following proposal from the United Nations: The Universal Declaration of Human Rights describes the family as the natural and fundamental unit of society, it follows that any choice and decision with regard to the size of the family must irrevocably rest with the family itself, cannot be made by anyone else. In addition, Hardin pointed out the problem of individuals acting in rational self-interest by claiming that if all members in a group used common resources for their own gain and with no regard for others, all resources would still be depleted.

Overall, Hardin argued against relying on conscience as a means of policing commons, suggesting that this favors selfish individuals – known as free riders – over those who are more altruistic. In the context of avoiding over-exploitation of common resources, Hardin concluded by restating Hegel's maxim, "freedom is the recognition of necessity", he suggested. By recognizing resources as commons in the first place, by recognizing that, as such, they require management, Hardin believed that humans "can preserve and nurture other and more precious freedoms". Hardin's article was the start of the modern use of "Commons" as a term connoting a shared resource; as Frank van Laerhoven & Elinor Ostrom have stated: "Prior to the publication of Hardin’s article on the tragedy of the commons, titles containing the words'the commons','common pool resources,' or'common property' were rare in the academic literature." They go on to say: "In 2002, Barrett and Mabry conducted a major survey of biologists to determine which publications in the twentieth century had become classic books or benchmark publications in biology.

They report that Hardin’s 1968 article was the one having the greatest career impact on biologists and is the most cited". Like Lloyd and Thomas Malthus before him, Hardin was interested in t
