This study aimed to employ remote sensing technology RS and geographic information systems (GIS) in detecting the change in vegetation coverage and its relationship to rain in Abha province in the Kingdom of Saudi Arabia. The study relied on the analytical approach with the use of the cartographic method through satellite visuals of different dates, on which the Normalized Difference Vegetation Index (NDVI) and Overlay analysis were applied in the ArcGIS geographic information systems program, with the aim of measuring the differences in vegetation coverage during two different years (1988 and 2019). , and two different months (January and June), in order to determine the places of change of vegetation coverage, based on the processing and analysis of four satellite images of Landsat satellites from the LOI (TM) and LOI), in addition to the statistical and field method. The study found a negative change in plant coverage in January with a change in plant coverage that amounted to (-26.9%), while that change was positive in June with a change in plant coverage that amounted to (38.2%). The study recommended the need for integration between the various parties interested in protecting the vegetation coverage and university educational institutions to exchange experiences and work on joint research projects, each according to their specialization, in order to achieve full benefit in providing environmental protection for plants in tourist areas in particular, while imposing environmental protection conditions through which sustainable development of vegetation is achieved.
