Climate change significantly impacts global food security by altering agricultural productivity and access to resources. Changes in temperature and precipitation patterns can reduce crop yields, affect food supply chains, and increase the prevalence of pests and diseases. Vulnerable populations, particularly in developing countries, may face heightened risks of food scarcity and malnutrition as agricultural systems struggle to adapt. Furthermore, extreme weather events, such as droughts and floods, can devastate harvests, exacerbating food insecurity. Addressing climate change through sustainable agricultural practices is vital for ensuring long-term food security and resilience.
