Characterization and delineation of farming situations of Durg district

Abstract

The soil is the most vital and precious natural resource that sustains life on the earth. The native ability of soils to supply sufficient nutrients has decreased with higher plant productivity levels, associated with increased human demand for food. The study area is an increase in soil depth, water holding capacity, cation exchange capacity and preponderance of calcium and magnesium ions. Land and water both are the limiting resources of living thing so that it is required to understand their importance and efficient use. Remote sensing and GIS is the advance tool to investigate the land resources and make plan by policy makers for its better utilization. Farming situation tells about the land suitability for cultivation. The Multi Criteria Evaluation (MCE) approach is used for the characterization of farming situation. Various thematic maps such as NDSI, slope, LULC and texture map was used for the characterization and delineation of farming situation. Multi Criteria Evaluation (MCE) approach was applied to estimate different farming situation through assigning the weights of indicators and sub-indicators into account their influences in selecting suitable farming situation. Based on that the four orders of farming situation were categorized such as Bhata, Matasi, Dorsa and Kanhar. The area under Matasi is highest 1028.20 sq km (43.59%) among all of them followed by Dorsa 957.92sq km (40.61%) and Kanhar 214.39 sq km (9.09%). Whereas Bhata having least area 120.97 sq km (5.13%). Another class of water body was also separately classified and it was found that 37.18 sq km (1.58%), in the study area.
