This food policy report is a response to growing concerns about the impacts of climate change on Latin American economies, agriculture, and people. It assesses both local and global effects of changing agricultural yields on the economy, subnational regions, and different household types, including male- and female-headed households in Brazil, Mexico, and Peru. The three countries reflect economic and geographic diversity in Latin America and more than half of the region’s population. Climate change impacts tend to be relatively small at an economywide level in all three countries. However, sectoral and household-level economic impacts tend to be diverse across countries and subnational levels. They mainly depend on projected changes in agricultural yields, the share of agriculture in regional gross domestic product (GDP), crop-specific international trade balances, net food buyer/seller position, and income diversification of households. As for gender, results from this study suggest that female-headed households may be less vulnerable than male-headed households to the effects of climate change, highlighting the importance of considering women as a source for solutions for building resilience to climate change. Given the relatively small impacts of climate change and the degree of uncertainty associated with them, it is too early to define specific policy recommendations. All three countries should try to maximize the benefits that may come with higher agricultural world market prices and to minimize the losses from reductions in agricultural yields.

According to the United Nations, the world’s population will grow by 2 billion people over the coming decades to reach 9.7 billion by 2050 (UNDESA-DP 2019a). The dignity and life prospects of those additional 2 billion people will depend on their ability to meet basic needs, such as food, clothing, and shelter, and their access to adequate employment. The most pressing need for jobs will be felt in those regions and countries that have not yet gone through the demographic transition, and where the cohort of young people is growing rapidly. The challenge will be compounded by an increasingly crowded, more competitive world with fewer natural resources per capita, and by the threat of climate change, which is projected to affect every sector of the economy (Arent 2014).

This report assesses the cost of adaptation to climate change across a range of future climate scenarios and investment options. We focus on offsetting climate change impacts on hunger through investment in agricultural research, water management, and rural infrastructure in developing countries. We link climate, crop, water, and economic models to (1) analyze scenarios of future change in the agriculture sector to 2050 and (2) assess trade-offs for these investments across key Sustainable Development Goals (SDGs) for poverty, hunger, and water. Our reference projections show that climate change slows progress toward eliminating hunger, with an additional 78 million people facing chronic hunger in 2050 relative to a no-climate-change future, over half of them in Africa south of the Sahara. Increased investments can offset these impacts. Achieving this would require that annual investment in international agricultural research increase from US$1.62 billion to US$2.77 billion per year between 2015 and 2050. Additional water and infrastructure investments are estimated to be more expensive than agricultural R&D at about US$12.7 billion and US$10.8 billion per year, respectively, but these address key gaps to support transformation toward food system resiliency. Findings on ranges of costs and trade-offs and complementarities across SDGs will help policymakers make better-informed choices between alternative investment strategies.
