The surface of the earth is undergoing rapid land-use/land-cover (LULC) changes due to population growth, various anthropogenic activities and natural phenomena. The main aim of the study is to quantitatively understand the decadal changes of LU/LC in Miniwada Panchayat using remote sensing data and GIS techniques. Supervised classification-maximum likelihood algorithm was applied in ArcGIS to detect LU/LC changes using multi-spectral satellite data obtained from Landsat TM and Landsat-8 for the years 2005 and 2015, respectively. The study area was classified into five major LU/LC classes, viz., waterbodies, forest, agricultural land, fallow land and others. Change detection was performed to quantify the conversions of LU/LC from 2005 to 2015. Ground truth observations were also taken into consideration to check the accuracy of the classification. The results indicate that during the decade, the agricultural land showed 3.61% decline; at the same time, land under others (include settlement and government areas) showed an increase of 15.28%. LU/LC changes have a wide range of consequences at all spatial and temporal scales. The study reveals that the LU/LC pattern and its spatial distribution are the major rudiments for the foundation of a successful land-use strategy required for the appropriate development of any area.
