Data

Over the past 10 years, food and nutrition crises have shifted from one-off emergencies to protracted conditions in many regions around the world, according to the 2026 Global Report on Food Crises (GRFC) released today. Since 2016, the global share of people facing acute food insecurity has nearly doubled. In 2025, 266 million people across 47 countries/territories experienced acute food insecurity; what’s more, 33 of those countries have appeared in every GRFC edition released since the report’s inception in 2016.

Understanding how food demand responds to income and price changes is essential for anticipating global food needs and expected consumption patterns, and for designing effective food policies. Two key parameters for this are the income elasticity of demand—the percent change in consumption in response to a percent change in people’s income; and the price elasticity of demand—the percent change in consumption in response to a percent food price change. These are essential inputs in a wide range of economic models.

With food crises on the rise, with an estimated 295.3 million people facing high levels of acute food insecurity in 2024. In the face of these stark hunger levels, policymakers, humanitarian organizations, development practitioners, and private sector actors urgently need knowledge about how to effectively enhance the resilience of local and regional food systems.

Food, land, and water systems face daunting challenges in the future, and the body of research exploring these challenges is growing rapidly. This note is part of a series developed by the CGIAR Foresight Initiative to summarize what we know today about the future of various aspects of food systems. The goal of these notes is to serve as a quick reference, point to further information, and help guide future research and decisions.

Key messages

Millions of people across 22 countries and territories may be pushed into acute food insecurity by May 2025, according to the latest FAO-WFP Hunger Hotspots Report. Ongoing and increasing conflict in many areas of the world, along with economic hardships and extreme weather caused by climate change and the La Niña phenomenon, are behind this significant increase in both the magnitude and the severity of acute food insecurity.
