The Problem
Desertification is not just about drought conditions.
The forces causing desertification are both natural (e.g., long-term changes in rainfall patterns that limit the growth of stabilizing vegetation) and human (e.g., overgrazing, deforestation, and other unsustainable agricultural practices).
The Role of Climate Change
The climate has already been changing rapidly in Africa, with projections for continued warming and shifts in precipitation patterns (Blunden and Arndt 2020).
As climate disruption continues, mass migration within Africa will likely worsen food insecurity, as nations which have sufficient food supplies for their populations will face pressures to provide food to those in need.
Solutions
For example, the Great Green Wall was envisioned as an 8000 km long swath of trees crossing the entire continent to halt the movement of Saharan sands.
