Desertification is the process of degradation of agricultural lands and turning them into dry, uncultivable deserts due to factors such as climate change, incorrect settlement, removal of vegetation, and others. Desertification negatively affects food security in several ways: deterioration agricultural area, lack of water resources, and increased hunger and social instability.  In order to combat desertification and protect food security, measures must be taken to reduce the increase in desertification and improve the management of water resources. This includes implementing sustainable irrigation techniques, conserving biodiversity and encouraging sustainable agricultural practices. It also requires international cooperation to combat climate change and implement policies aimed at reducing greenhouse gas emissions and enhancing the sustainability of agriculture in areas vulnerable to desertification. Solving the problem of desertification requires joint efforts from governments, the international community, farmers, and non-governmental organizations so as to ensure food security for affected communities.
