Abstract

Land degradation at the current pace is projected to render more than half of the cultivated land in Africa unusable by 2050. Human drivers of land degradation include demographic growth, grazing pressures, agricultural practices, agricultural expansion, forest clearing and fuel wood harvesting. This briefing paper provides an overview of the interactions between land degradation, human activity and climate change in Africa, with suggestions for policy responses. One of the principal signs of land degradation is the loss of soil organic carbon; land degradation interacting with climate change is an urgent challenge.
