The governance of natural resources used by many individuals in common is an issue of increasing concern to policy analysts. Both state control and privatization of resources have been advocated, but neither the state nor the market has been uniformly successful in solving common-pool resource problems. After critiquing the foundations of pol icy analysis as applied to natural resources, Elinor Ostrom here provides a unique body of empirical data to explore the conditions under which common-pool resource problems have been satisfactorily or unsatisfactorily solved. Dr. Ostrom first describes three models most frequently used as the foundation for recommending state or market solutions. She then outlines theoretical and empirical alternatives to these models in order to illustrate the diversity of possible solutions. In the following chapters she uses institutional analysis to examine different ways - both successful and unsuccessful - of governing the commons. In contrast to the propositions of the " tragedy of the commons" argument. common-pool problems sometimes are solved by voluntary organizations rather than by a coercive state. Among the cases considered are communal tenure in meadows and forest, irrigation communities and other water rights. and fisheries. Governing the Commons makes a major contribution to the analytical literature on institutions and to our understanding of human cooperation. Elinor Ostrom is co-director of the Workshop in Political Theory and Policy Analysis and professor of political science at Indiana University.
Elinor Ostrom’s 8 rules for managing the commons
The commons are those things that we all own together, that are neither privately owned, nor managed by the government on our behalf. Some are large scale and somewhat abstract, such as the English…

Commons
The commons are the cultural and natural resources accessible to all members of a society, including natural materials such as air, water, and a habitable Earth. These resources are held in common even when owned privately or publicly. Commons can also be understood as natural resources that groups of people manage for individual and collective benefit. Characteristically, this involves a variety of informal norms and values employed for a governance mechanism. Commons can also be defined as a social practice of governing a resource not by state or market but by a community of users that self-governs the resource through institutions that it creates.
New to the Commons? | David Bollier
If you’re coming to the commons for the first time, it can be difficult to grok the idea because there are so many different ways to understand the commons. That’s because the commons is not so much a fixed, universal thing as a general concept describing durable, dynamic sets of social relationships for managing resources -- all sorts of resources: digital, urban, natural, indigenous, rural, cultural, scientific, to use some crude categories.

Think Like a Commoner | A Short Introduction to the Life of the Commons
In our age of predatory markets and make-believe democracy, our troubled political institutions have lost sight of real people and practical realities. But if you look to the edges, ordinary people are reinventing governance and provisioning on their own terms. The commons is arising as a serious, practical alternative to the corrupt Market/State.

A Practical Framework for Applying Ostrom’s Principles to Data Commons Governance
How do stakeholders govern themselves? What drives their endeavour? How do they make decisions? How do they make sure conflict does not tear them apart? The answers to these questions will look different for every data commons. Learn more in this week's data governance blog.

Kami of the Commons: Towards Designing Agentic AI to Steward the Commons
Commons suffer from neglect, free-riding, and a persistent deficit of care. Inspired by Shinto animism -- where every forest, river, and mountain has its own \emph{kami}, a spirit that inhabits and cares for that place -- we provoke: what if every commons had its own AI steward? Through a speculative design workshop where fifteen participants used Protocol Futuring, we surface both new opportunities and new dangers. Agentic AI offers the possibility of continuously supporting commons with programmable agency and care -- stewards that mediate family life as the most intimate commons, preserve collective knowledge, govern shared natural resources, and sustain community welfare. But when every commons has its own steward, second-order effects emerge: stewards contest stewards as overlapping commons collide; individuals caught between multiple stewards face new politics of care and constraint; the stewards themselves become commons requiring governance. This work opens \emph{agentive governance as commoning design material} -- a new design space for the agency, care ethics, and accountability of AI stewards of shared resources -- radically different from surveillance or optimization.

The Commons, Short and Sweet | David Bollier
I am always trying to figure out how to explain the idea of the commons to newcomers who find it hard to grasp. In preparation for a talk that I gave at the Caux Forum for Human Security, near Montreux, Switzerland, I came up with a fairly short overview, which I have copied below. I think it gets to the nub of things.
ORGANISING PRINCIPLES — THE ALTERNATIVE
This makes the difference between a localism that cannot sustain itself because it is simply too small with limited resources of skills and expertise. And one that is able to build its own regenerative economy, entirely through access to the global commons.

AI and The Enclosure of the Scientific Commons
The scientific literature can be viewed as an "information commons:" an intangible resource that "no one owns and is shared by everyone." There are well-established economic and political frameworks for understanding such commons, emerging from the history of agricultural common lands found in places like preindustrial England. This article provides a primer on the history and these frameworks, and considers a key difference between the information commons and the fields of yore: while information commons are robust and immensely valuable --- some can be said to rank among humanity's greatest achievements --- the English agricultural commons no longer meaningfully exist. The latter are gone not because of the well-known "tragedy of the commons," but rather a phenomenon known as the enclosure movement (~1600--1800) that transformed the common lands into private property. Many observers, then and now, judge enclosure to have been theft at a societal scale. This article argues that artificial intelligence (AI) provides precisely the tools needed to enable a previously-infeasible enclosure of the information commons. Although AI-enabled enclosure does not operate identically to physical enclosure, it shares the key features of turning the commons into private wealth and undermining the social systems that support them (via "slop spam"). The concepts presented in this article can provide a scholarly basis for interrogating the foreboding feeling that AI may represent not just a smash-and-grab, but an attack upon a whole way of life.

Reinventing Commons Governance in Modern Times | David Bollier
I gave the following remarks about commons governance on September 27 as part of the U!REKA Lab Lecture Series. U!REKA -- which stands for Urban Research and Education Knowledge Alliance -- is a consortium of eight European universities that studies urban commons. The subtitle of my talk was "Find Answers by Living the Questions."
