The impact of global drought on agriculture is of serious concern among scientists, farmers and policy makers. Increasing drought, triggered by climate change, is affecting agricultural production worldwide, causing reduced crop yields and harming economies. First, food crops such as rice, corn and wheat are very vulnerable to drought. A decrease in water supply dries out the soil, which inhibits photosynthesis and damages plant roots. For example, in many areas of Sub-Saharan Africa, prolonged drought has caused agricultural productivity to decline by up to 50%. Second, the impact of drought is not only visible in crop yields, but also in the quality of production. Plants stressed by a lack of water tend to have lower nutrient content. Research shows that drought can reduce protein levels in corn and wheat, which impacts people’s food security. Furthermore, global drought is affecting irrigation systems. Many farmers depend on irrigation to maintain soil fertility. When water sources dry up, irrigation operational costs increase. This encourages farmers to switch to crops that are more resistant to dry conditions, often giving up their resistance to existing climate variations. In the socio-economic aspect, drought can cause food instability. The increase in food prices resulting from a decrease in production can cause food insecurity, encouraging the migration of people looking for more fertile places to farm. This creates social tensions in areas with limited resources. On a global scale, data shows that the agricultural area affected by drought has increased by 20% in the last five years. Countries with dry climates, such as Australia and countries in the Middle East, are worst affected by changing rainfall patterns and higher temperatures. To overcome this problem, sustainable agricultural technology innovation is very important. Practices such as water harvesting and using more drought-tolerant plant varieties can help increase climate resilience. Additionally, precision farming systems that utilize technology-based weather data can help farmers manage resources more efficiently. Agricultural ecosystems need to be maintained by developing techniques such as crop rotation and agroforestry, which can improve soil structure and maximize water absorption. With these steps, the negative impacts of global drought can be minimized, providing hope for a more sustainable agricultural future.
