The Enclosure Of The Commons — A History That Repeats Until It Is Understood

The Commons as an Institution

The tragedy of the commons — the thesis that shared resources will be systematically overexploited because individual users have incentives to take as much as possible while the costs are shared — was formalized by Garrett Hardin in a 1968 Science paper that became one of the most cited articles in the environmental literature. Hardin's argument provided an intellectual justification for either privatization or state control of shared resources: without an owner or a regulator, common resources would be destroyed.

The problem with Hardin's argument, as Elinor Ostrom systematically demonstrated across decades of fieldwork and analysis (and for which she received the Nobel Prize in Economics in 2009), is that it describes an open-access resource — one with no management rules — not a commons in the historical sense. Real commons, as Ostrom documented in fishing communities in Maine, irrigation systems in Spain, alpine pastures in Switzerland, and forest management in Japan, were governed by sophisticated, community-developed rules that successfully managed shared resources for centuries without either privatization or state control.

The pre-enclosure English commons were not Hardin's tragedy waiting to happen. They were institutions with clear rules about who had rights, what those rights permitted, how violations were handled, and how rules were adjusted as conditions changed. Manor courts adjudicated commons disputes. Stinting — rules about the maximum number of animals each rights-holder could graze — prevented overuse. Seasonal access rules protected resources during critical periods. These systems were not perfect, but they were functional and resilient in ways that became apparent only after they were destroyed.

The enclosures did not save the commons from Hardin's tragedy. They ended institutions that had been preventing that tragedy, and replaced them with private ownership that generated different dysfunctions: consolidation, absentee management, monoculture, and the systematic exclusion of the rural poor.

The Mechanism of Enclosure

Enclosure follows a consistent pattern across its historical and contemporary instances:

First, identification. A shared resource that has value — land, fisheries, spectrum, genetic information, software protocols, financial market infrastructure — is identified as exploitable. The resource has been managed by a community or held in common because it is difficult to divide or because collective management was functionally superior.

Second, reframing. The shared resource is reframed as a problem. It is inefficient (not maximizing monetary output), ungoverned (though it may be governed by non-monetary rules), wasted (in the sense that it is not generating maximum extractable rents). The framing serves to delegitimize existing management arrangements and create public justification for change.

Third, legal redefinition. Property law is revised, sometimes through legislative action, sometimes through regulatory reinterpretation, sometimes through judicial decision, to recognize a private claim to the previously shared resource. The mechanism varies, but the function is to create an enforceable exclusive right where previously there was a shared one.

Fourth, enforcement. The newly created private right is enforced against former users, who are now trespassers. The community that managed the resource is excluded. Customary users become criminals if they continue their customary practices.

The Parliamentary Enclosure Acts followed this pattern exactly. The legal mechanism was the act itself, which extinguished customary rights that had no standing in the commercial property law the acts codified. The enforcement was the hedge and ditch — the physical enclosure that marked the new boundary and excluded former users.

Contemporary Enclosures

The pattern has recurred in every sector where shared or open resources have become valuable.

Spectrum enclosure: Radio frequency spectrum was initially an open resource used by amateurs, commercial broadcasters, and government agencies under informal coordination. The Communications Act of 1934 and subsequent legislation created licensed spectrum rights assigned by the FCC. Spectrum auctions beginning in the 1990s converted these licenses into tradeable private property worth hundreds of billions of dollars. The electromagnetic spectrum — a physical commons that no one created — was enclosed into private hands through regulatory redefinition.

Genetic enclosure: Plant genetic resources, developed over millennia by farming communities through selection, breeding, and exchange, were historically treated as a common heritage of humanity. The Plant Variety Protection Act (1970) and the Plant Patent Act (1930) created intellectual property rights over plant varieties in the United States. The Trade-Related Aspects of Intellectual Property Rights (TRIPS) agreement (1994) extended this framework globally, requiring WTO member nations to provide intellectual property protection for plant varieties. Genetic sequences that had been maintained as common heritage — in farmers' fields and public seed banks — became private property through legal redefinition, without compensation to the communities that had developed them. (This theme intersects with concept 413 on open-source seeds.)

Internet enclosure: The early internet was built on open protocols — TCP/IP, HTTP, SMTP — maintained by a commons of academic researchers and developers. The commercial internet built private value on top of this open infrastructure. Over time, network effects concentrated web activity in a small number of platform monopolies (Google, Facebook, Amazon) that effectively enclosed the commons of human attention and communication. Users who contribute content, data, and network value to these platforms receive none of the equity value created — a structural analog to tenants who improve land while paying rent to an owner who captures the improvement value.

Data enclosure: Personal data generated by individuals' use of digital services is collected, aggregated, and monetized by platform companies. The individual whose behavior generates the data receives no payment; the platform captures the commercial value. This is an enclosure of a new kind of commons — the data record of human activity — through legal structures that treat data possession as ownership.

Genetic sequence enclosure in pharmaceuticals: COVID-19 vaccine development made the enclosure logic visible in an acute form. Genetic sequences isolated by researchers at the NIH and universities — publicly funded — became the foundation for vaccine intellectual property worth tens of billions of dollars to Pfizer and Moderna. The public research commons was enclosed into private IP that then excluded the populations of low-income countries from affordable access.

The Repeating Pattern and Why Understanding Matters

Each contemporary enclosure has been accompanied by the same rhetorical moves as the original: the shared resource is portrayed as inefficiently managed, the private ownership is portrayed as necessary for investment and improvement, and those who resist are portrayed as opponents of progress or defenders of backwardness.

In each case, the actual history of the resource contradicts the framing. Open-source software has produced more technically sophisticated infrastructure than most proprietary software. Open scientific publishing produces more citeable research than proprietary journals. Farmer-maintained genetic diversity has produced more adaptable crop varieties than the proprietary seed industry. The commons were not failures. They were working institutions destroyed in the interest of private appropriation.

The intellectual tools for understanding this — Ostrom's framework for commons governance, the historical literature on enclosure, the political economy of property law — have been available for decades. The pattern continues because the political power to enclose persistently exceeds the political power to resist.

Recognizing enclosure is the first step in resisting it, and resistance has succeeded. The open-source software movement created Linux, Apache, and the internet's technical infrastructure outside proprietary enclosure. The Creative Commons licenses created legal infrastructure for shared creative work. Community land trusts have removed land from market enclosure in hundreds of communities. Indigenous communities have successfully defended land rights and genetic resources from corporate enclosure in dozens of legal proceedings. The Nagoya Protocol (2010) created an international framework for benefit-sharing from genetic resources, partially limiting the ability of corporations to enclose traditional biological knowledge.

The Planning Principle

Every commons that exists is maintained against the continuous pressure of enclosure. The pressure does not stop because it is resisted once; it returns in new legal forms, new economic framings, new technology platforms that concentrate what was previously distributed.

Planning for sovereignty requires not only accessing commons — seeds, knowledge, code, land, water — but actively maintaining the legal, social, and institutional structures that keep them open. This is not a passive act of using what exists. It is an active, ongoing political and legal practice of defending shared resources against the recurring logic of privatization.

The history that repeats is not inevitable. It repeats because the organizational capacity of those who benefit from enclosure consistently exceeds the organizational capacity of those who depend on the commons. Building the latter — through community institutions, legal advocacy, cooperative ownership structures, and political organization — is the practical work of preventing history from repeating.
