The International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT) was developed in the early 1990s to explore the long term challenges facing policymakers in reducing hunger and poverty in a sustainable fashion. The IMPACT model has been expanded and improved repeatedly to respond to increasingly complex policy questions and the state-of-the-art of modeling. See documentation of most recent update.
Currently, IMPACT is a network of linked economic, water, and crop models. At its core is a partial equilibrium multi-market economic model, which simulates national and international agricultural markets. The links to water and crop models support the integrated analysis of changing environmental, biophysical, and socioeconomic trends, allowing for in-depth analysis on a variety of critical issues of interest to policymakers at national, regional, and global levels.
Many publications and other resources based on IMPACT analyses are available below. Also available is an online visualization tool providing key results from recent IMPACT analysis in an easy-to-access format.
