The commons is a new way to express a very old idea—that some forms of wealth belong to all of us, and that these community resources must be actively protected and managed for the good of all.

The commons are the things that we inherit and create jointly, and that will (hopefully) last for generations to come. The commons consists of gifts of nature such as air, oceans and wildlife as well as shared social creations such as libraries, public spaces, scientific research and creative works.

Biopiracy: The practice where traditional knowledge of natural resources, especially medicinal and agricultural plants, is appropriated by international companies to create products, for which they are awarded exclusive rights to use under patent laws.

Cap-and-dividend: A practical solution to the problem of global climate disruption, based upon the commons principle that the atmosphere belongs to everyone. (Also known as the Sky Trust.) First articulated by On the Commons co-founder Peter Barnes in his 2002 book, Who Owns the Sky? cap-and-dividend is a response to cap-and-trade proposals in which polluters are granted permission to buy and sell pollution rights as a way to curb carbon and other emissions causing global warming. This essentially gives existing polluters ownership of the air in order to create incentives to reduce emissions. Cap-and-dividend starts at the same place by creating a cap on pollution that gradually reduces the amount of greenhouse gases that can be dumped into the air and creating a market where the right to pollute can be bought and sold. But rather than letting historical polluters reap all the financial benefits, fees that companies pay to pollute would be collected and returned to citizens in the form of a regular dividend. This is not only a more equitable way to distribute the wealth created by a commons, it also increases public support for measures to stop global climate change. For more information see Peter Barnes 2008 book Climate Solutions

Common assets: Common assets are those parts of the commons that have a value in the market and which are appropriate to buy and sell (see “inalienability”). Radio airwaves are a common asset, for example, as are timber and minerals on public lands and, increasingly, air and water. By recognizing certain resources as common assets, it becomes natural to ask: Are the common assets being responsibly managed on behalf of the general public or a distinct community of interest? Is the capital being depleted?

Commons movement: A growing social and political movement that believes the commons is a crucial sector of the economy and society and useful prism for talking about resources that should be shared. The commons offers not only an affirmative vision of a more equitable, eco-friendly society: it also serves as a countervailing force to keep excesses of the market and government sectors in check. Some speak of an emerging commons paradigm as a new way of looking at the world, one that opens up the competitive, mechanistic, profit-centric mindset that has ruled Western civilization since the dawn of the Industrial Revolution, with a more humanistic, environmentally aware and holistic world view. A wider appreciation for the enduring importance of the commons has developed over the last eight years, especially among people deeply involved in the politics of water issues, the internet, the over commercialization of culture and public spaces. This world view is now reaching into many other arenas, including economics, the environment, social justice and numerous citizens movements around the world.

Copyleft: This refers to a license that allows free re-use and modification of creative work so long as any works derived from the original remain available on the same terms. Copyleft, formally known as the “General Public License” or GPL, was initiated by computer programmer Richard Stallman and the Free Software Foundation. By protecting the creativity and energy of the commons from private appropriation, the GPL has enabled communities of programmers to build shared bodies of code, such as free software and open source software. A similar set of licenses for other types of creative works has been devised by the “Creative Commons”:http://creativecommons.org.

Corporation: A self-perpetuating legal entity whose mission is to maximize short-term return to shareholders. In its aggressive pursuit of this mission, the corporation not only produces new innovations and efficiencies, it also displaces costs onto the environment, our communities and our personal lives (see externality).

Enclosure: Historically, this refers to the privatization of common grazing lands beginning in 15th Century England, which impoverished many peasants. Today it is used to describe the conversion of a commons into private property. Enclosure entails not just the privatization of a resource, but also the introduction of money and market exchange as the prevailing principles for managing that resource. Enclosure shifts ownership and control from the community at large to private companies. This in turn changes the management and character of the resource because the market has very different standards of accountability and transparency than a commons. (Contrast a public library with a bookstore, or Main Street with a private shopping mall.) Because of its compulsion to extract maximum short-term rents and externalize costs, market enclosure often results in the “tragedy of the market.”

Externality or illth: A social or ecological cost that is not paid by its creators. As the scope of market activity expands beyond a certain point, engulfing more of nature and daily life, it yields less and less happiness and wellbeing even as it causes more and more unintended problems. In market logic, the expanding output must be regarded as “progress” and “wealth.” In fact, the accelerating pace of the market machine is producing more “illth” ??” the opposite of wealth. Author Peter Barnes ( Who Owns the Sky ) has popularized this term, coined by John Ruskin in the 19th century, to describe the unintended but increasing destruction of nature, social disruptions, health problems and other (unacknowledged, unintended or disguised) costs of market activity.

Gift economy: A community of shared purpose, such as an academic discipline, whose members give time and creativity to the community and reap benefits in return. In gift communities, money is an unacceptable “currency” because relationships are rooted in personal, particular and historical experiences of each individual, and cannot be converted into cash or any other fungible unit. Despite the absence of cash, legal contracts and market exchange, a gift economy can be tremendously productive, efficient and innovative, as seen in free and open software communities, online wikis and other collaborative websites, blood donation systems and scientific research disciplines.

Inalienability: The principle that a given resource shall not be freely bought and sold in the marketplace, but shall remain intact, in its natural context. Inalienability derives from a social consensus that certain things and behaviors are so precious and basic to human identity that they are degraded if they are put up for sale. “Goods” that have traditionally been regarded as inalienable include votes, babies, bodily organs, sex, genes, living species and most aspects of nature, but market forces are increasingly challenging long-standing norms of inalienability.

Land trusts: An alternative model of land ownership in which a tract of land is owned by a non-profit organization??“usually to preserve its natural assets or to maintain it as affordable housing. There are more than 1,600 land trusts in the US today encompassing 37 million acres. Land trusts provide a good example of how a commons economic model can exist outside the realm of both government and private control as a distinct sector for advancing the public good. Professor Carol Rose of Yale Law School has cited land trusts as an example of “property on the outside, commons on the inside”—meaning that the resource exists within the market system as legal property yet is managed internally according to commons principles.

Open source software: (See copyleft) Open source software is functionally similar to free software that is protected under the General Public License, or GPL, except that open source programs allow a program to be freely copied, modified and distributed, but do not require it. In addition, the open source community does not necessarily subscribe to the political agenda of Richard Stallman, founder of the Free Software Foundation, who regards the GPL as the foundation for a vision of political and creative freedom. Open source programmers tend to be more focused on the practical value of open source code in developing superior software.

Public goods: Resources that, because of their “public” nature, are difficult or costly to exclude anyone from using. Examples include lighthouses, city parks, broadcast programming and the global atmosphere. In the lingo of economists, these are “non-rival” and “non-excludable” resources. Government often steps in to pay for public goods because it is difficult to get individual beneficiaries to pay for them. But in the networked environment of the Internet, it is increasingly feasible for self-organizing groups to create and pay for public goods. Open source software is a prime example.

Public space: Any place where people are free to gather for social or civic interaction. The value of public spaces is increasingly being recognized as essential to the health of local communities and democratic societies in general. While usually defined as parks, streets and sidewalks, plazas, libraries and public institutions, the concept can also be expanded to include congenial privately owned settings such as a coffee shop, corner grocery or a plaza outside an office building. Shopping malls, which in many suburban communities function as Main Street, have stirred controversy by forbidding civic activities such as gathering signatures for petitions??“a policy upheld by the courts which worries many civil liberties and public space advocates.

Public trust doctrine: A legal doctrine that says that the state holds certain resources in trust for its citizens which cannot be given away or sold. Public trust doctrine has its origins in Roman law, which recognized that certain resources such as fisheries, air, running water and wild animals belong to all. Under the doctrine of res communes , the king could not grant exclusive rights of access to a common resource. The point is that there is a clear distinction between common property (which belongs to the people) and state property (which can be controlled and mismanaged by government).

Tragedy of the commons: Title of an influential 1968 essay by biologist Garrett Hardin, which argued that overuse of common resources is a leading cause of environmental degradation. This was interpreted by some, especially economists and free-market libertarians, to mean that private ownership is preferable to the commons for the stewardship of land, water, minerals, etc. Yet in recent years many have challenged this view on both empirical and philosophical grounds. Professor Elinor Ostrom of Indiana University has been a leading figure in demonstrating the practical utility and sustainability of commons governance regimes, particularly in developing countries. Other analysts, such as Professor Yochai Benkler of Harvard Law School, have shown how people in online commons can indeed collaborate sustainably to produce and protect valuable resources. This suggests that the vision of human behavior implicit in the tragedy of the commons metaphor is not as immutable as many economists assert, and that collective management is an eminently practical governance strategy in many circumstances. The tragedy of the “anti-commons” is now frequently invoked to describe the problems associated with excessive privatization and fragmentation of property rights, such that collective action for the common good is thwarted. An example is the proliferation of patents on bio-medical knowledge that impedes research on cures for malaria, or the proliferation of copyrights in film and video that prevents documentary filmmakers from clearing the rights to images for use in new films.

Trust or stakeholder trust: A legal institution for protecting the commons and managing any assets that may arise from it. If the corporation is the preeminent institution of the market, the trust is the premier institution of the commons. The managers of a trust, the trustees, have clear legal responsibilities to manage its resources on behalf of the beneficiaries. This includes strict fiduciary responsibilities, transparency and accountability. (See land trusts)

Value: Economists tend to regard “value” as a quantifiable object with a price tag. But as commoners realize, “value” can also be something intangible and not available for sale. An example is the social satisfaction of belonging to a community and contributing to a shared goal. A commons can also create economic value as efficiently as a market; examples include Wikipedia, the online user-generated encyclopedia, and Craiglist, the online advertising service. The difference is that a commons usually does not convert its output into a marketable commodity.
