The impact of global drought on food security is an increasingly urgent and relevant issue in the context of current climate change. Droughts, characterized by reduced rainfall and increased temperatures, threaten production of key agricultural commodities such as wheat, corn and rice. Reducing crop yields due to drought directly affects global food supplies and increases food prices, which in turn can trigger a food crisis. One of the most significant consequences of drought is reduced food production. Dry soil is unable to support plant growth properly, causing reduced crop yields. According to research, areas that are usually fertile can turn into deserts in a short time if exposed to prolonged drought. For example, corn plants that are particularly sensitive to soil moisture levels can experience yield reductions of up to 50% under serious drought conditions. The drought also changed agricultural patterns. Farmers may be forced to switch to more drought-resistant crop varieties, but this may not necessarily be profitable in the long term. Impacts on biodiversity, due to reduced plant variety, can result in greater vulnerability to pest and disease attacks, and can damage agricultural ecosystems. In addition to its direct impact on crop yields, drought also affects food security through economic hardship. Rising food prices due to decreased supply can make food increasingly unaffordable for people, leading to increased hunger rates, especially in developing countries. In countries that rely heavily on agriculture, the impact on farmers’ incomes can also lead to population movement to cities, exacerbating urbanization problems. Water resources are under greater pressure due to drought. Many countries rely on irrigation to support their agriculture, so when water sources dwindle, farmers must compete for limited water supplies. This can increase social conflict and have a negative impact on political stability. Drought mitigation efforts through the adoption of sustainable agricultural technology are the key to maintaining food security. The use of more efficient irrigation techniques, better soil management, and selecting drought-tolerant plant varieties can help increase yields amidst increasingly severe climate challenges. Collaboration between countries is also important in dealing with this problem, with the control and distribution of water resources a priority. Early warning systems and research to find innovative solutions must be integrated into global agricultural policies to address the threat of drought. In a global context, attention must be paid to addressing impacts that not only threaten agricultural yields but also human survival in various parts of the world.
