Trade

In today’s global economy, international agricultural trade plays an increasingly important role in ensuring food security. But domestic and international policies as well as administrative restrictions can hinder trade flows between domestic and foreign markets and producers. Policies to achieve domestic objectives in one country can affect trade flows in ways that lead to indirect effects in other countries.

IFPRI’s research informs the design of domestic and international trade policies in developing countries, as well as regional and global negotiations to promote an inclusive and efficient international trade system. This includes work on the impact of tariffs, quotas, and nontariff barriers as well as market-distorting food safety and environmental regulations, export bans aimed at food security, and agricultural support payments.

IFPRI partners with institutions to strengthen developing countries’ capacities to do their own research and independently develop long-term, sustainable trade policies that help to eradicate poverty and support food security. To support rapid responses to market disruptions, IFPRI maintains the Food Security Portal, which provides early warning on international price changes and restrictive trade policies.

IFPRI’s research on this topic is closely aligned with the Sustainable Development Goals (SDGs), including SDG1, SDG2, SDG16, and SDG17, and contributes to the CGIAR Impact Areas on Nutrition, Health, and Food Security and Poverty Reduction, Livelihoods, and Jobs.

Haunted by tariffs and trade wars: A positive trade policy for US agriculture

Haunted by tariffs and trade wars: A positive trade policy for US agriculture

US farmers have been among the biggest beneficiaries of US free trade agreements and the postwar creation of a rules-based global trading system. Under recent administrations, however, farmers have been disadvantaged by the US shift away from forging such trade pacts. Agriculture has also been one of the sectors most affected by the volatility and uncertainty of the first and second Trump administrations’ high tariffs and trade wars. Both Trump administrations have compensated farmers for lost export revenue, but such a trade policy is not a sustainable long-term solution and cannot replace a more positive policy that improves trade rules and expands farmers’ market access abroad.

The International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT): Model documentation for version 4

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 since its initial development in the early 1990s, IMPACT version 4 represents the latest iteration of the model, offering an enhanced treatment of complex issues such as climate change, food security, and economic development. IMPACT 4 modeling system 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.

How does Trade Risk Influence Agricultural Policy?

International trade provides critical access to food, especially for countries that cannot cost-effectively produce enough domestically. If importing food is cheaper, why do so many countries keep protecting their own agricultural production, especially considering the core tenet of international trade that countries should specialize in producing goods in which they hold a comparative advantage? This […]
