ASSESSMENT AND MONITORING OF DEGRADED LAND USING REMOTE SENSING AND GIS TECHNIQUES

ENVIRONMENTAL ENGINEERING

Land degradation leads to a shift in environmental and economic activities due to declining productivity and quality of land. It is seen as an act or more that reduces the current and / or potential volume of soil production. This means a decline from the highest to the lowest region due to declining global energy, productivity, and biodiversity loss. The current status of degraded land in India is found to be 147 million hectares (Mha) of land, including 94 Mha from erosion, 16 Mha from acidification, 14 MH from flooding, 9 MH from erosion , 6 Mha from salt, and 7 Mha from compounding. This is even worse because India supports only 2.4% of the world's land area. Apart from its limited territory in the world, India is ranked second in the world in terms of farm output. Therefore, it becomes a major test problem. The aim of the current study is to prepare basic data to combat land degradation and to conserve land resources effectively with the help of geospatial technology - Remote Sensing (RS) and Geographical Information System (GIS) - Rasulabad Block, Kanpur district. Different levels of analysis were performed to assess the magnitude of the different types of land in the study area namely Sodic land, Saline land. Degradation to assess of saline or salt-free soils and calcareous or sodium soils and comparing this information with satellite studies the spatial variability of these soil structures is shown on soil maps created in the GIS area. The results showed that the soil in the study area was at risk of salt infiltration and erosion which could be traced mainly to irrigation activities in the Rasulabad Block in the Kanpur region. A temporary study of the 2017 and 2021 Sentinel satellite datasets was also done to find the parameters that are responsible for land degradation, respectively.
