Global drought is one of the biggest threats to world food security. As climate change becomes more pronounced, the frequency and intensity of drought events is increasing, affecting agricultural land, food production and the ecosystem as a whole. To understand its impact, it is important to dig deeper into how drought affects food security in different parts of the world. First, drought causes a decline in agricultural productivity. Most agricultural areas depend on sufficient rainfall for crop growth. When rainfall decreases, food production such as grains, vegetables and fruit is at risk of experiencing a drastic decline. Data shows that in drought-prone countries such as Ethiopia and Sudan, crop yields can decline by up to 50% in one growing season. Second, drought not only reduces food quantity, but also its quality. Plants experiencing drought stress often have lower nutrient content, which can have a negative impact on people’s health. For example, micronutrient deficiencies due to reduced food quality can trigger health problems such as stunting in children and anemia in pregnant women. In addition, the economic impact of drought is also significant. Farmers who are unable to meet the expected harvest are forced to face financial losses. This causes debts that disrupt their welfare, as well as affecting the local economy. Many farming families struggle to meet basic needs, which in turn exacerbates the problem of poverty. Droughts also trigger social instability and conflict. When food supply decreases, food prices tend to increase, causing food insecurity. In some cases, this can lead to protests or even riots. For example, in several countries in the Middle East, increases in food prices due to drought have been linked to the wave of demonstrations sweeping the region. Mitigation and adaptation efforts are very important in dealing with this problem. Sustainable agricultural innovations, such as the use of drought-tolerant plant varieties and efficient irrigation techniques, are becoming increasingly crucial. Educational programs for farmers on good agricultural practices can help them adapt to climate change and reduce its risks. Mitigation also needs to be carried out at the policy level. Governments and international organizations must work together to develop policies that support food security. Investment in agricultural technology research and development can improve food security, and it is important to do so globally. The role of the international community is very important in overcoming this drought. Cooperation between countries in preparing for and dealing with the impacts of drought can strengthen world food security. Through joint commitment, it is hoped that we can reduce the impact of drought and ensure that the world continues to provide enough food for everyone. By understanding and responding to the threat posed by drought, strategic steps can be taken to protect global food security, ensuring the availability of sufficient and quality food for future generations. Food security is not just about quantity, but also about access and availability of quality nutrition.
