The International Institute for Applied Systems Analysis (IIASA) is a world-renowned international research institute that plays a primary role in resolving complex global change matters. The results of IIASA research and the expertise of its researchers are made available to policymakers in countries around the world to help them produce effective, science-based policies that will enable them to face these challenges. The work of IIASA is made possible through the generous support of a range of organizations and individuals that share the institute’s commitment to independent, interdisciplinary research into pressing global problems. The research is sponsored by agencies in member countries in Africa, the Americas, Asia, and Europe and from contracts, grants, and donations from governments, international organizations, academia, businesses, and individuals. These diverse sources of income enable IIASA to perform research that is truly independent.
