RRI partners participated in a lively discussion of common property rights and customary systems of communal resource management at the 12th Biennial Conference of the International Association for the Study of the Commons in Cheltenham, United Kingdom. The conference provided an opportunity to exchange knowledge on shared resources or ?commons? between developing and developed world, between practitioners and researchers, and between old and ?new? commons; and spur discussion on new ways of using, managing, protecting and creating what many understand as ?commons?.
