6. How can we prevent or reverse desertification?
Reduced rainfall may be induced if vegetation cover is lost due to overcultivation, overgrazing, overharvesting of medicinal plants, woodcutting, or mining activities. This is usually coupled with the effect of reduced surface evapotranspiration and shade or increased albedo (C22.2.3, C22.2.2, C13 Box 13.1).
