概要	Common-pool resource (CPR) diagnostics evaluate a self-governing commons against the design principles that Elinor Ostrom, in Governing the Commons (1990), found to characterize long-enduring institutions for managing shared resources. A common-pool resource is one from which it is hard to exclude users but where one person's use subtracts from what is left for others, creating dilemmas of overuse and underprovision. Ostrom's comparison of irrigation systems, fisheries, forests, and grazing commons that had survived for generations against those that had collapsed yielded eight design principles, from clearly defined boundaries and rules matched to local conditions, through collective-choice arrangements, monitoring, graduated sanctions, and conflict resolution, to recognized rights to organize and nested enterprises. A later systematic review by Cox, Arnold, and Villamayor-Tomas confirmed and refined these principles. The method uses them as a diagnostic checklist to assess and explain the robustness of commons institutions.	Participatory Geographic Information Systems (PGIS), and the related Public Participation GIS (PPGIS), are approaches in which communities themselves create and use spatial data and maps to represent local spatial knowledge for resource management, land and resource tenure, and planning. Spanning a continuum from sketch mapping with sticks and stones on the ground to georeferenced data held in formal GIS, the approach merges the empowering ethos of participatory development, articulated by Robert Chambers, with the analytical and communicative power of geographic information technology.
