Greening for the Greater Good : Socio-Economic Impacts of Land Restoration in the Great Green Wall
We analyse the mid-term socioeconomic impacts of the Action Against Desertification in Northern Nigeria. AAD is a large-scale land restoration and livelihood development project aimed at halting the process of desertification in the Sahel, while sustaining these outcomes through improvements in household incomes and food security. Our evaluation uses a multi-method strategy to generate more rigorous evidence on landscape restoration and its impacts at household level. We input pre-restoration remote-sensed data into a machine learning-algorithm to identify comparable pieces of land to the programme’s restoration sites. We then select comparison households from communities bordering these sites through a replication of the AAD’s targeting process. Our impact evaluation strategy is based on propensity score adjustment techniques, applied to both survey and remote-sensed data. The main finding is that land restoration activities did not negatively affect food security, despite some restrictions imposed to the use of communal land, and that it led to a decrease in moderate food insecurity. Households in restoration areas changed their livelihood strategies towards more climate resilient activities, increasing their participation in sales of livestock by-products and of high-value NTFP. The analysis also provides an innovative approach to ex post evaluations of future land restoration programmes
