الملخص EN

The phenomenon of desertification is one of the most serious environmental phenomena that threaten the dry and semi-arid areas due to the overlap of natural factors, geological and geomorphological accompanied by dry climatic characteristics on the one hand, and human pressure in the exploitation of available resources on the other hand, This study is designed to study the phenomenon of desertification and its environmental impact on the area of Al-Ayyana, which shows the role of natural factors of temperature and humidity, and the low precipitation and evaporation in the aggravation of desertification in the region.

The study showed the high rate of evaporation throughout the year.

The study also highlighted the role of the human factor of overgrazing, logging and land use for hiking or planting which played a large role in the expansion of desertification, Through the climatic data, drought indicators were determined by using numerical equations which proved that the AL-Ayyana area is within the dry desert range.

The study also showed low vegetation based on spatial data.
