Land degradation typically stems from both human-related and natural factors; overfarming, overgrazing, climate change, and extreme weather are the most common causes. Beyond affecting land and the natural environment, land degradation poses serious threats to agricultural productivity, food security, and quality of life. Nowhere is this issue more urgent than in sub-Saharan Africa, where an estimated 500 million people live on land undergoing desertification, the most extreme form of land degradation.
