**2. Desertification processes**

Desertification may occur as a result of one process or the interaction of several functions. For example, wind erosion is one of the essential desertification processes in arid regions of the world, which alone or combined with other processes leads to desertification. The main desertification processes refer to the destruction of plant resources, soil resources, soil erosion, and water erosion, which are further explored below. In addition to natural factors, policies in Greece or Europe in recent decades have been reported to contribute to intensive land cultivation, overgrazing, rural–urban migration, etc., which directly affect desertification [6].
