The International Institute for Applied Systems Analysis (IIASA) is a nongovernmental research organization.
It conducts inter-disciplinary scientific studies on environmental, economic, technological and social issues in the context of human dimensions of global change and acted as coordinator of the Global Energy Assessment (GEA) (www.globalenergyassessment.org) for Rio+20. Sustainability and the human dimensions of global change are the key issues in IIASA's investigations. These driving forces are studied as individual topics and in the wider context of their relevance to changes in the global system. Systems methods for the analysis of global issues provide the mathematical and methodological backbone to the work of the applied projects at IIASA.
The Water (WAT) Program was established in 2013 in conjunction with a flagship project of IIASA, the Water Futures and Solutions Initiative (WFaS). The program seeks to incorporate water science into assessment and planning studies at the nexus of water, energy, food and environmental security. Its aim is to establish a critical mass of knowledge in the nexus through development of new modelling tools and data collection.
