Climate change is one of the greatest threats to global food security in the 21st century. Rising temperatures, unpredictable rainfall, and an increase in extreme weather events such as droughts and floods are disrupting agricultural production worldwide. Crops like wheat, rice, and maize — which form the backbone of the world’s food supply — are particularly vulnerable to heat stress and changing precipitation patterns. These shifts not only reduce crop yields but also affect the nutritional quality of food, worsening hunger and malnutrition, especially in developing countries. Water scarcity is another major challenge linked to climate change. As glaciers melt and rainfall patterns shift, freshwater resources are becoming less reliable. Farmers in many regions are facing difficulties irrigating their fields, leading to lower productivity. At the same time, soil degradation and desertification are expanding due to prolonged droughts and poor land management practices, further reducin...
