“Instead of there being a single solution to a single problem, I argue that a great variety of institutional arrangements can work to manage common-pool resources.”Elinor Ostrom · Governing the Commons · 1990 · Governing the Commons: The Evolution of Institutions for Collective Action, Chapter 1
Communities can manage shared resources themselves, through local rules they write, without the state or a single owner.
Many believed that if a pasture belongs to everyone, each person brings too many cows and the grass runs out for all. Ostrom studied real villages worldwide and found local rules, written by the people themselves, that prevented exactly this problem. Communities can make good rules, if allowed to.
Ostrom found that rules work when those who follow them also have a say in creating them. In a fishing village, for instance, people would not accept a law from the city banning fishing in a certain season. But if they themselves decide together when to let the fish reproduce, they follow that rule. This is the key: direct involvement in rules turns obligation into assumed responsibility. The next step is to understand how these rules are born in practice.
