Climate changes and their impact on the vegetation cover in Mandali district using remote sensing and geographic information systems.

Abstract

The vital environment in which man lives and performs his various activities is directly affected by the climatic changes that the world has witnessed in recent times and which have been confirmed by many studies. Greenhouse gases in the atmosphere will negatively affect the vital activity of plants, and it is worth mentioning that Mandali sub-district of Diyala Governorate suffers from scarcity of water resources and lack of vegetation cover, so the aim of the research is to identify the general trend of annual rainfall and temperature of the region for the period (1990-2021) And linking climatic effects on the vital environment, and the information was drawn from the digital processors of the landsat satellite data for the period (1990-2021) and on four models to be the subject of the study and generate information for the use of mathematical and geospatial criteria in revealing the relationship between climate change and the deterioration of vegetation in the region and trying to develop scenarios The future of what the vital environment will lead to in order to develop an integrated management to avoid environmental disasters for the region in general .
