Global drought is a serious problem that threatens food security throughout the world. Increasing climate change is causing erratic weather patterns, resulting in decreased rainfall in many areas. The impact of this drought is far-reaching, affecting agricultural production, food access and public health. First, the main impact of drought on agricultural production is a decrease in crop yields. Plants need water to thrive, and a lack of water can cause plant stress, leading to stunted growth and reduced yields. Yields of major grain crops such as wheat, rice and corn are also threatened. This decline in crop yields not only reduces food supplies but also triggers an increase in global food prices. Second, the impact of drought is not only felt by farmers. Lack of water for irrigation causes instability in the food system, which impacts national food security. Countries that depend on agriculture as a source of income and food are very vulnerable to weather fluctuations. When food supplies decrease, people’s access to nutritious food will shrink, causing malnutrition problems, especially among children and vulnerable populations. Furthermore, the psychosocial impact of drought needs to be considered. Drought stress can trigger mass migration, with farmers changing professions or seeking more fertile land. This not only affects the economic life of farmers, but also creates social tensions in new areas, which can lead to conflict. As the frequency and intensity of drought increases, adaptation becomes key to maintaining food security. The development of crop varieties that are more resistant to drought and the use of agricultural techniques that are more efficient in water use are essential. In addition, implementing sophisticated irrigation systems can help maximize water use in agriculture. Technology also plays an important role in mitigating the impacts of drought. Satellite monitoring and soil sensors can provide accurate data on crop water and soil moisture requirements, which helps farmers in data-based decision making. Innovation in data management is very important to improve food security in this era of climate change. The importance of collaboration between government, the private sector and society in overcoming the impacts of drought cannot be ignored. Sustainable water resources management policies and education programs for farmers on adaptation techniques can build long-term resilience. Global drought is having a profound impact on food security, involving complex dynamics between agriculture, economics and society. Understanding and appreciating these impacts is the first step towards effective and sustainable solutions.
