In an interview with Nature Climate Change (Vol 3. Jan 2013), Prof. Pavel Kabat — director and CEO of the International Institute for Applied System Analysis in Austria — called for a long-term system approach to water research, new partnerships with the developing world and a change in donor practices, to tackle water-climate issues. During his visit to Pakistan, Prof. Kabat will visit LUMS on Friday, March 20th, 2015 and give a lecture on global and regional challenges related to water. He leads the International Institute for Applied Systems Analysis (IIASA) based at Laxenburg, Austria. IIASA was created in the peak of the Cold War during the 1970's and it became a world leading institute for trans-disciplinary and cross-sectoral systems science applied towards multiple aspects of global and regional transformations ranging from environment, energy and climate to financial, economic and demographic transitions. IIASA is an independent, global international science and science to policy institute with currently 22 member countries and more than 2000 international staff (~350 in residence staff) ) across the an entire range of disciplines, from mathematics to sociology. Narrowly focused, single-disciplinary science alone cannot adequately underpin policies and solutions to resolve major sustainability challenges.
