Centers (CRCs) that utilize a common research methodology and database that includes a diverse array of variables taken from the environmental and social sciences; the design of the IFRI research instruments is based on the Institutional Analysis and Development (IAD) framework and previous theoretical and empirical studies. The IAD framework, developed by colleagues at the Workshop in Political Theory and Policy Analysis at Indiana University, provides a unique way for researchers to transcend disciplinary boundaries; IFRI focuses and collects data on institutional, social, and ecological variables which can be stored in a single IFRI database, and analyzed to understand the inter-relationships among social and ecological processes and outcomes.
