Abstract

This article encompasses the vital role of Remote Sensing and Geographic Information System in assessingthe change of vegetation cover in Dzhezkazgan, Central Kazakhstan. The study site is well-known forcopper mining operations which serves as one of the major source of livelihood among residents situated inthe area. However, this manifestation implies with land degradation which is detrimental to vegetation. Thisresearch aims to assess quantitatively the ability of Normalized Difference Vegetation Index (NDVI) to extractmeaningful vegetation abundance information by acquiring satellite images (i.e. Landsat Thematic Mapper™, Enhanced Thematic Mapper Plus (ETM+), and Operational Land Imager (OLI)). The NDVI for land coverchanges in a copper mining area were analyzed for the five different years – 1976, 1986, 1996, 2006 and2015. The LANDSAT MSS imagery for 1976 and Landsat Surface Reflectance imagery for the years 1986and 2015 were used for the study. NDVI differencing is used to come up with land/vegetation cover changedetection analysis. The results showed a significant decrease in vegetation due to an increase in the area ofmining areas. This study will greatly assist the local executive body, as well as mining organizations, in takingappropriate measures to ensure sustainable development of the region and the environment.
