Planning for the future of food is difficult because food systems are extremely complex – driven by changes in population, income, technology, climate, and other factors – and the goals of decision-makers and other stakeholders are extremely diverse (and sometimes conflicting). Based on recent results from IFPRI’s International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT), this presentation will explore how biophysical and socioeconomic simulation models can be used to explore alternative possible food system futures, identify challenges and solutions, evaluate tradeoffs, and inform the choices we face today.   Bio: Keith Wiebe is a Senior Research Fellow in the Foresight and Policy Modeling Unit at the International Food Policy Research Institute (IFPRI), where he leads a research program on global foresight. In addition to foresight, his areas of particular interest include climate change, natural resource management, agricultural productivity, and food security. Prior to joining IFPRI in 2013, he was Deputy Director of the Agricultural Development Economics Division of the United Nations Food and Agriculture Organization (FAO) in Rome, where he managed a program of economic research and policy analysis for food security and sustainable development, and helped coordinate preparation of FAO’s annual flagship reports on the State of Food and Agriculture and the State of Food Insecurity in the World. Previously, he was Deputy Director of the Resource and Rural Economics Division of the US Department of Agriculture’s Economic Research Service in Washington, DC. He received his BA in Economics from Carleton College, and his MA and PhD in Agricultural Economics from the University of Wisconsin-Madison.
