Rewriting the rules: How U.S. tariff paths could reshape global trade

This paper examines how the recent shift in United States tariff policy could reshape global agricultural trade and influence the stability of food systems worldwide. Using the MIRAGRODEP computable general equilibrium model, the analysis evaluates three policy scenarios that reflect the current trajectory of trade tensions: the North America scenario, the Liberation Day tariff package, and a renewed U.S.–China tariff confrontation. The scenario results reveal distinct lessons. The North America scenario shows that deeply integrated regional markets are extremely sensitive to tariff shocks, and even moderate tariff increases within North America lead to significant disruptions in agricultural trade and measurable welfare losses for Canada and Mexico. The Liberation Day scenario demonstrates that unilateral tariff escalation reduces U.S. competitiveness across a wide range of agricultural products and triggers substantial trade diversion toward countries with preferential access, particularly Mexico, which becomes the primary beneficiary of redirected U.S. import demand. The China scenario highlights that renewed U.S.–China tariff escalation produces severe distortions, especially in oilseed markets, as prohibitive tariffs drive China to shift its purchases almost entirely toward South American suppliers, sharply lowering U.S. export prices and fragmenting global supply chains. Across all scenarios, global agricultural trade contracts, supply chains become less efficient, and food systems become more exposed to climate and geopolitical shocks. These findings underscore the need for predictable and coordinated trade policies that limit uncertainty rather than amplify it. Strengthening trade diversification, investing in supply chain resilience, and aligning economic and geopolitical objectives remain essential for safeguarding global food security in an increasingly unstable trade environment.

Cuando la geopolítica amenaza la sostenibilidad global

En los últimos años, el mundo ha entrado en una fase de gran inestabilidad geopolítica que está cambiando la forma en que los países se relacionan en materia de comercio, clima y desarrollo sostenible. El resurgimiento del unilateralismo y las medidas centradas en el interés nacional están debilitando la cooperación internacional, un pilar esencial para avanzar en los objetivos ambientales y climáticos acordados en foros multilaterales como el Acuerdo de París.

A good global investment for the United States: How investing in CGIAR makes America stronger, safer and more prosperous

This report documents how CGIAR investments have delivered substantial economic, security, and diplomatic benefits for the U.S. that far exceed financial contributions. By driving agricultural innovation and providing evidence-based insights, CGIAR has boosted U.S. farm productivity, expanded export markets, and made food more affordable for American consumers. It has also helped prevent billions of dollars in potential damage from pests and diseases that threaten U.S. food security and farm livelihoods. CGIAR promotes American leadership in agricultural innovation by supplying the majority of the genetic materials used in U.S. crop breeding and acting as a critical research partner for U.S. businesses and universities. CGIAR also makes America safer and stronger through its work on predicting crises, protecting food security, and on improving livelihoods as an alternative to migration.
