The result of a collaborative effort between the World Resources Institute (WRI), the International Food Policy Research Institute (IFPRI), intergovernmental organizations, agencies, research institutes, and individual experts in more than 25 countries worldwide. The Pilot Analysis of Global Ecosystems (PAGE) compares information already available on a global scale about the condition of five major classes of ecosystem: agroecosystems, coastal areas, forests, fresh-water systems and grasslands. The results of the PAGE are summarized in World Resources 2000-2001, a biennial report on the global environment.
