The main impact of climate change on global food security is the disruption of agricultural productivity. Changes in temperature and precipitation patterns can lead to reduced crop yields, increased pests and diseases, and altered growing seasons. This directly affects the availability, access, and stability of food supplies. Additionally, the frequency of extreme weather events, such as droughts and floods, threatens food production systems. As a result, vulnerable populations, particularly in developing regions, face heightened food insecurity. Addressing climate change is essential for promoting sustainable food systems and ensuring global food security.
