Description Research article
Soil erosion has serious impact on socioeconomics, environment and agricultural production system.Soil erosion has been a prime concern for north-east India due to its hilly terrain, heavy rain fall andshifting cultivation. Morphometry along with land use land cover (LULC) information are essentialaspects of watershed prioritization for soil erosion control as well as soil and water conservation. Thepresent study intends to assess the soil erosion potential of Meghalaya plateau (Umsning) region ofnorth-east India by analyzing different morphometry parameters along with existing land use landcover using multi-criteria analysis method. A total of 11 sub-watersheds (SW1 to SW11) were identifiedin the Umsning block using digital elevation model (DEM) and geographic information system (GIS)tools. Morphometric parameters affecting soil erosion along with LULC were used as criteria of rankingand compound values were obtained for final prioritization. Based on morphometric analysis, SW-1,SW-2, SW-3, SW-4 and SW-6 falls under extremely high priority group, whereas based on land coveronly SW-1 falls under extremely high priority group. However, multi-criteria analysis combining bothmorphometry and LULC, suggest that the SW-1, SW-3 and SW-6 were falling under extremely highpriority group while SW-7 was classified under very low priority. Planners and policy makers to developintegrated watershed management plan for socio-economic and environmental sustainability of the areacan use the reported information
