FAO's work on climate change

Climate change threatens our ability to ensure global food security, eradicate poverty and achieve sustainable development. In 2016, 31 percent of global emissions originating from human activity came from agrifood systems. This includes deforestation, livestock production, soil and nutrient management, and food loss and waste. The increasing concentrations of greenhouse gases are trapping more heat in the atmosphere, which causes global warming.

Climate change has both direct and indirect impacts on agrifood systems due to shifting and unpredictable rainfall patterns and temperatures, a higher incidence of extreme weather events and disasters such as drought, floods, outbreaks of pests and disease and ocean acidification.

FAO is supporting countries to adapt to climate change and to mitigate climate change by reducing or preventing greenhouse gas emissions, through its projects and programmes and a wide range of knowledge products.

Extreme heat is emerging as one of the most urgent and least understood threats to agriculture and food security. Rising temperatures, prolonged heatwaves, and shifting climate patterns are already disrupting crop yields, livestock health, water availability, and rural livelihoods – with impacts falling disproportionately on the most vulnerable.
