Dr. J. Kropp: Senior scientist at PIK; he studied chemistry and physics and in 1992 he took a diploma in theoretical chemistry at the University of Oldenburg. His doctoral thesis in theoretical physics was on Neural Networks and Qualitative Knowledge Bases in Environmental Systems Analysis. From 1993-1998 he was research fellow at PIK, from 1998-2001 project leader of a research project on costal zone management (Data integration and Qualitative Dynamics in the Wadden Sea) at the Institute for Chemistry and Biology of the Marine Environment (University of Oldenburg), and from 2001 research analyst and member of staff of the German Advisory Council on Global Change to the Federal Government (WBGU). He was a member of an expert council on New Concepts and Indicators in Fisheries and Aquaculture invited by the European Commission/DGXII and a contributor to the WBGU reports Transition to sustainable energy systems and special report Charging the global commons, and project leader of the international joint project Scaling Analysis of Hydrometeorological Time Series at the University of Giessen, Institute for Theoretical Physics. During 1999-2002 he was the PI for an integrated vulnerability assessment for the German state government of North-Rhine Westphalia. His research interests are the development of methods for integrated impact assessments, in particular, with respect to vulnerability, risk assessment, and adaptation to climate change and in the context of decision making and various institutional settings. Amongst the research project he leads are Uncertainty, Prediction and Risk Assessment of Extreme Events (UPRACE) and Development of Policies and Adaptation Strategies to Climate Change in the Baltics (ASTRA) which is of particular interest for the suggested project. For the latte he was awarded with the Amber Tree Award of the European INTERREG Office for the outstanding vision of the project bringing together various disciplines.He worked for the Council of
