Sustainable Livelihoods and Social Development Project (SLSD) The South East of Afghanistan has largely remained at the margins of the development efforts of the past decade. Widespread poverty, weak institutions and scarce public services characterize the environment. The Sustainable Livelihoods and Social Development Project (SLSD) aims to improve the living conditions of poor rural families through irrigation infrastructures, agriculture techniques and income generation activities and by strengthening basic public service delivery.
