New Report: Climate Change Affects Every Step of the Food Value Chain

Researchers from the International Food Policy Research Institute (IFPRI) have published an extensive report highlighting the effects of climate change on agriculture and global nutrition. The report, Climate Change and Variability: What are the Risks for Nutrition, Diets, and Food Systems?, compiles evidence-based research to provide a detailed look at food security, agriculture, and food systems in relation to climate change. The authors also examine future projections in these areas, seeking to acknowledge the complexity and importance of those relationships as both global population and global temperatures rise.

The report frames the food system as both a victim and a driver of climate change: while climate change negatively affects agriculture and the ability to feed the world, the food system intensifies climate change by significantly contributing to global greenhouse gas emissions (GHGs).

In an introductory post, the reports’ authors urge more research and action, calling the task of ensuring adequate global nutrition for all “the challenge of our lifetime.” The authors cite research projecting that at current rates of climate change, “it is likely that global food production will decline by two percent every decade until at least 2050, just as the world’s population is expected to reach 9.7 billion people.”
