摘要：Environmental study was carried out to describe a geographical area and its biodiversity. The example here shows the features of human nutrition habits and quality of life with specific study of negative impact on the environment and Earth resources.Tuti Island in Sudan was prone to this complex problem so it is taken as a case study. The hypothesis is that the use of RS and GIS could help in reconstruction of unused territories so it could help to solve the problem. Changes of land use and land cover were observed using classified Landsat 5 images in 1972, Landsat 7 in 1985 and Landsat 8 in 2018.The results showed that several temporal changes occurred beside turning dense tree cover land into lands with other landuse purposes for 1972, 1985 and 2018. Agricultural zones (crops and trees) were major dominant zones in 1972, 1985 and 2018. In addition, populated residential areas increased through time but not as significantly as trees, sand and cropping landuse areas (P=0.89082) as for the classified Landsat 8 image acquired in 2018. Ecosystem planning through GIS and RS could be a good way to solve most of these issues for the future of Tuti Island landuse.
