Vegetation cover changes NDVI in the district of Alexandria in the province of Babylon for a period 1990-2020

Abstract

This research presents a method to discover the change of the vegetation cover in the district of Alexandria in the province of Bablon by analyzing two images of the land satellite (7-8) based on the vegetation tabulations of the standard difference in (NDVI). It uses NDVI, one of the multi-spectral remote sensing data technology, to find the vegetation content. It classifies the land cover according to its vegetation density, as well as finding water bodies and open or free vegetation areas. These land resources can be easily interpreted by calculating this indicator. The NDVI method is applied according to its characteristics to a low-density vegetation cover of (25%) and a medium-density vegetation cover of (0.9%) for the year 1990, while in 2020 one region was obtained, which is a low-density vegetation cover, and it appeared at a rate of (13.5), and the amount of vegetation loss was shown for the year 2020 by 12.5%. Simulation results show that NDVI is very useful in detecting surface features of the visible region which is very useful for policy makers in decision making. Vegetation analysis can be useful in predicting unfortunate natural disasters that warn of human lack of awareness of the importance of plants and encroaching on them and turning them into residential areas. In addition to the need to develop new protection strategies.
