A COMPREHENSIVE GEO –SPATIAL STUDY ON THE IMPACT OF SALINITY: CHALLENGES TO AGRICULTURAL YIELD IN MATLA –BIDYADHARI INTERFLUVE

Increasing salinity is a major concern to the tropical coastline agricultural system. To ensure crop production and to satisfy food requirement, land reform system should be revamped in Matla –Bidyadhari interfluvial region, south 24 paraganas West Bengal. This study shows the effectiveness of GIS and Remote Sensing techniques in measuring impact of salinity on agricultural planning. The research work covers 809 sq. km area of Gosaba and Basanti Block, West Bengal. Soil samples were taken from various ground control points of these Blocks. After getting that information, soil clay fraction map, drainage map, land use map, salinity zonation map has been created by using satellite data on Arc GIS 10.6 software. These thematic maps can be use in agricultural planning. To cope with increasing salinity, it is recommended, deep water irrigation in dry season. Vegetables are more sensitive than cereal crops to salinity, so they can be yield in seasonal variation.
