Degraded lands, widespread across sub-Saharan Africa, are used mainly for grazingand firewood harvesting and have low agricultural production potential. Such areashave become degraded through overuse and removal of surface cover and associatederosion processes and are termed hardpans. Hardpans with high clay content, highcation exchange capacity (CEC) and water holding capacity have productivepotential. ICRISAT has developed and scaled a gender sensitive approach Bioreclamationof Degraded Land? (BDL) that combines water harvesting technologies(planting pits, half-moon and trenches), application of compost and plantation ofhigh value fruit trees and annual drought tolerant indigenous vegetables. Inpartnership with CRS in Niger, BDL was scaled to over 3000 villages (2014-18) whichled to many benefits in food security and income generation for the localpopulation. To scale further multi-spectral remote sensing based imagery of highresolution (10 m) can identify and map hardpans and differentiate higher potentialsites for the BDL approach. These maps will be used to quantify the area underhardpans and the potential area in which the interventions can be scaled up
