Food Security

The realities of a changing climate are becoming increasingly clear, with temperatures rising around the world and extreme weather events, like flooding and droughts, becoming more and more frequent. April 2025 was the second hottest April globally on record, and evidence suggests such anomalous high temperatures could become the norm rather than the exception.

The world faced a stark inflection point in 2024, as the continued rise in the number of people facing crisis-to-catastrophic levels of acute food insecurity meets sharp reductions in funding for humanitarian assistance. The 2025 Global Report on Food Crises (GRFC), released today, reports that 295.3 million people across 53 countries/territories faced acute food insecurity in 2024. This represents a tripling of the number of people facing acute hunger since 2016 and a doubling since 2020 (Figure 1).

Fertilizer prices experienced a significant surge in 2021, driven by the post-COVID 19 global economic recovery. Russia’s February 2022 invasion of Ukraine propelled prices even higher. Broad economic sanctions on key fertilizer exporters Russia and Belarus exempted agricultural products but triggered further economic disruptions. Overall, the conflict heightened market uncertainties regarding the availability of potash, phosphate, and nitrogen-based fertilizers in international trade.

The problem of food loss and waste (FLW) undermines global food and nutrition security and makes a significant contribution to climate change, primarily through greenhouse gas (GHG) emissions. Reducing or minimizing FLW requires coordinated action to align stakeholders, promote responsible investments, and incentivize sustainable agricultural practices.

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.
