Commons scholars, particularly those from the Bloomington School tradition, have a long and rich history of studying various environmental commons such as forests, fisheries, pasturelands, and irrigation systems. These environmental commons have been thoroughly documented and analyzed across diverse contexts, providing a solid foundation for empirical research and theorization on social and environmental governance. Recently, new types of environmental uses and commons have been identified and analyzed, including coral reefs, the atmosphere and the space beyond the atmosphere, the high seas and the deep seabed. This theme invites submissions that focus on the management of both traditional environmental commons—forests, fisheries, and irrigation systems—and newer and larger-scale environmental commons. We welcome contributions that explore the use, management, distribution, and conservation of environmental commons across different contexts, as well as the interconnections among them. In keeping with the IASC’s foundational principles, a central focus of this sub-theme will be on the theory and practice of building local institutions for governing environmental commons in a changing world.
