This study focuses globally on the effects of desertification and drought on agricultural lands. Desertification, which shows more its effects from region to region all over the world and particularly on certain continents, contains factors that will disturb the human future. One of these negative factors is the risk of creating food vulnerability by directly damaging agricultural areas. The risk of desertification reducing the quality of human life and threatening other living plants and habitats is a very important issue that should be highlighted by the international system. In this context, the study draws attention to the negative impact of global desertification, as well as the reduction of agricultural and arable land and the risks of declining crop yields. Among other problems caused by desertification, the study emphasizes socio-economic instability due to migration and climate-related conflicts, world hunger and lack of grain and food. In the study, the literature on global desertification, drought and arable agricultural land was searched and selected source information from the literature is included in the study. In addition, the study was supported by maps, graphs, and tables, as well as desertification researches and analyzes. Due to the limitation of the pages, other factors, such as global warming triggering desertification, have not been addressed, and environmental issues, which are directly damaged by desertification other than arable agricultural areas, are excluded from the field of this study.

Key words: Desertification, drought, arable agriculture, food insecurity, hunger, vulnerability
