Land degradation poses daunting challenges to Niger and the country has designed several policies and strategies for combatting it. Building on work past studies, this study uses new satellite data which have higher resolution and run for longer time – thus capturing the longterm land management dynamics. This study also uses an improved cost of land degradation model which nets out benefits from land improvement as well analysing the impacts of land degradation on food and nutrition security.
