ABSTRACT

 

Remote sensing was used to analyze and study land use/land cover change and its impact on environment of Guna city, Madhya Pradesh (Central India). The population growth and land use activities continues to exert immense pressure on both its resource and environment. Accordingly, a study was scoped to ascertain the magnitude of land use/land cover change, and assess its impact on local environment over the past 12 years. Land use/land cover details have been carried out by visual interpretation method of remote sensing data of IRS, LISS II and LISS III, FCCs of band combination 2, 3 and 4. The interpreted data is supplemented as well as cross checked by field visits. In addition to this, Normalized Difference Vegetation Index (NDVI) has been generated from multi-spectral Landsat ETM+ data. The change detection for 1989 and 2001 showed an increase in uncultivated land by 25.65%, wasteland by 5.66%, water body by 1.19% and built-up land by 3.60%. There has been a decrease in the area under cultivated land by 5.77%, dense forest by 1.10%, open forest by 23.33% and open scrub by 5.90%. However, rainfall has decline by about 186.93 mm in annual average rainfall during the past 18 years.
