Abstract
Abstract: Sodic land is one of the major problems that has become an extensive challenge in today’s scenario, which act as a threat to global food productivity. Detrimental climatic changes are acting as a catalyst in the development of soil salinity, thereby increasing the problem in the upcoming future and ultimately effects the unaffected areas. This paper aims to integrate information from previously published literature about the extent, expansion rate, prevailing situation and current policies for handling soil sodicity as well as evaluating the sustainability of reclaimed sodic land. Since Sodic land reclamation has been done in the Indo-Gangetic region on a great extent in many states namely Uttar Pradesh, Punjab and Haryana in India. Although, in some areas, the reversion of reclamation has been reported. Therefore, this study has been done in one of the reclaimed sites of district Raebareli of Uttar Pradesh for sustainability assessment of sodic land using remote sensing, Geographic Information system (GIS) and necessary ground information. It was found that the villages of Singhpur and Tiloi blocks of Raebareli district were greatly affected by sodicity and had shown large extent of sodicity and reversion. Keywords: Raebareli district, Sodic areas, Remote sensing, Reclamation strategies, GPS.
