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.

The International Food Policy Research Institute’s International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT) supports analysis of long-term challenges and opportunities for food, agriculture, and natural resources at global and regional scales. IMPACT is continually being updated and improved to better inform the choices that decisionmakers face today. This document describes a new country-level version of the model. IMPACT-SIMM (International Model for Policy Analysis of Agricultural Commodities and Trade–Standard IFPRI Multimarket Model) is a partial equilibrium, multi-market, simulation model of the production, supply, and demand of agricultural commodities within a country or group of countries. It simulates the operation of agricultural markets, solving for equilibrium prices within a country and, in multi-country mode, global markets. It is designed to be a “portable” and potentially open-source version of the IFPRI (International Food Policy Research Institute) IMPACT3 model documented in Robinson et al. (2015). IMPACT-SIMM shares model specification, equations, and computer code with IMPACT3, but is designed to be more flexible in application. It allows users to specify a standard multi-market model at any level of aggregation by commodities and countries by changing data inputs, without any change in model code. This model system supports longer-term scenario analysis to provide researchers and policymakers with a flexible tool to assess and compare the potential effects of changes in biophysical systems, socioeconomic trends, technologies, and policies at the level of individual countries or groups of countries.

The International Food Policy Research Institute's International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT) supports analysis of long-term challenges and opportunities for food, agriculture, and natural resources at global and regional scales. IMPACT is continually being updated and improved to better inform the choices that decisionmakers face today. This document describes the latest version of the model. IMPACT version 3 expands the geographic and commodity scope of the model in response to desires expressed by researchers and policymakers to address more complex questions involving climate change, food security, and economic development into the future. IMPACT 3 is an integrated modeling system that links information from climate models (Earth System Models), crop simulation models (for example, Decision Support System for Agrotechnology Transfer), and water models linked to a core global, partial equilibrium, multimarket model focused on the agriculture sector. This model system supports longer-term scenario analysis through the integration of these multidisciplinary modules to provide researchers and policymakers with a flexible tool to assess and compare the potential effects of changes in biophysical systems, socioeconomic trends, technologies, and policies.

"The ongoing COVID-19 pandemic marks the most significant, singular global disruption since World War II, with health, economic, political, and security implications that will ripple for years to come." -Global Trends 2040 (2021) Global Trends 2040-A More Contested World (2021), released by the US National Intelligence Council, is the latest report in its series of reports starting in 1997 about megatrends and the world's future. This report, strongly influenced by the COVID-19 pandemic, paints a bleak picture of the future and describes a contested, fragmented and turbulent world. It specifically discusses the four main trends that will shape tomorrow's world: - Demographics-by 2040, 1.4 billion people will be added mostly in Africa and South Asia. - Economics-increased government debt and concentrated economic power will escalate problems for the poor and middleclass. - Climate-a hotter world will increase water, food, and health insecurity. - Technology-the emergence of new technologies could both solve and cause problems for human life. Students of trends, policymakers, entrepreneurs, academics, journalists and anyone eager for a glimpse into the next decades, will find this report, with colored graphs, essential reading.

The Agricultural Trade Policy Simulation Model (ATPSM) is designed of detailed analysis of agricultural policy issues. It can be used as a tool by researchers and negotiators alike for quantifying the economic effects at the global and regional level of recent changes in national trade policies. The Model covers 161 countries and 35 agricultural commodities, and includes an extensive database. The Model also provides estimates of changes in trade volumes, prices, government revenues and welfare indicators linked to changes in the general trade policy environment. The Model can be downloaded free from the UNCTAD website at http://www.uncatd.org/tab/.
