Abstract
In this study, impacts of rainfall
and land use changes on soil erosion in Nasarawa State, Nigeria in
changing climate, were investigated by applying remote sensing
techniques, Geographical Information System (GIS) and the Revised
Universal Soil Loss Equation (RUSLE). Results revealed that, changes in
rainfall intensity and land cover types are the core drivers of soil
erosion in Nasarawa State over 30-year (1985–2014) periods. Besides,
erosion rates and magnitude were more affected by changes in soil cover
than changes in rainfall amount. Therefore, agroecology agricultural
systems (e.g. soil mulching, minimum tillage, agroforestry, rotational
cropping systems, use of mechanical and biological anti erosive
measures) could be the most efficient way of combatting soil erosion
concerns while scaling-up rainfed agriculture adaptation.
