A Study of Land Use / Land Cover Changes in Three Blocks of Darrang District, Assam Using Geoinformatics
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 6
Abstract
The study is an attempt to analyse the changes in the land use / land cover pattern in three administrative blocks of Darrang district, Assam over a period of time (2003 to 2015) using the techniques of geospatial technology. Digital satellite imageries of IRS LISS III and high resolution Google earth images were used to demarcate the land use / land cover classes of the year 2003 and 2015. The study area is classified into six land use / land cover categories viz. Settlement (villages), Agricultural land, Forest, wetland, water body and river. Geographic Information System (GIS) was used to integrate the layers of land use / land cover classes of different time to quantify the changes. In addition to the study of overall changes in the land use / land cover over a period of time, category wise changes were also quantified and mapped. For each land use / land cover category the area unchanged, area extended and area reduced over a period of time were quantified and depicted in the respective maps. The land use / land cover category wise study provides the nature of change in each category over time. The overall land use / land cover changes were shown in the form of land use loss and gain map. The nature of changes of the land use pattern was also compared across the blocks. The study area falls under the three administrative blocks under Darrang district, Assam. The blocks include Sipajhar, Pub Mangaldai and Pachim Mangaldai; situated in the north bank of the river Brahmaputra. The total area of the three administrative blocks is 900 sq.km (approx.).Topographically, the study area is flat in nature which is situated in the alluvial plain of the Brahmaputra River, with some hillocks seen as inselberg.
