Bio

Keith Wiebe is a Senior Research Fellow in the Foresight and Policy Modeling Unit and Lead of the CGIAR Research Initiative on 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.

Climate change: Understanding impacts on agrifood systems and evaluating policy options

Climate change is a major challenge of our time, with global and far-reaching effects on and from agriculture and food systems. This chapter reviews the evolution of research on climate change, food security, and food systems, reflecting on IFPRI’s major contributions to understanding and modeling climate change impacts and identifying promising policies and investments for mitigation and adaptation.

Governance and resilience as entry points for transforming food systems in the countdown to 2030

Due to complex interactions, changes in any one area of food systems are likely to impact—and possibly depend on—changes in other areas. Here we present the first annual monitoring update of the indicator framework proposed by the Food Systems Countdown Initiative, with new qualitative analysis elucidating interactions across indicators. Since 2000, we find that 20 of 42 indicators with time series have been trending in a desirable direction, indicating modest positive change. Qualitative expert elicitation assessed governance and resilience indicators to be most connected to other indicators across themes, highlighting entry points for action—particularly governance action. Literature review and country case studies add context to the assessed interactions across diets, environment, livelihoods, governance and resilience indicators, helping different actors understand and navigate food systems towards desirable change.Due to complex interactions, changes in any one area of food systems are likely to impact—and possibly depend on—changes in other areas.

The International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT): Model documentation for version 3.6

The International Food Policy Research Institute’s IMPACT model is a robust tool for analyzing global and regional challenges in food, agriculture, and natural resources. Continuously updated and refined, IMPACT version 3.6 is the latest update to the model for continuously improving the treatment of complex issues, including climate change, food security, and economic development. IMPACT 3.6 multimarket model integrates climate, crop simulation, and water models into a comprehensive system, providing decision-makers with a flexible platform to assess the potential impacts of various scenarios on biophysical systems, socioeconomic trends, technologies, and policies.
