Desertification is “Degradation of land in arid, semi-arid, and dry sub-humid areas”.
Although there is generally a focus on soil degradation, desertification is closely linked to other forms of environmental degradation, such as deforestation, salinization, loss of biodiversity and destruction of habitat.
· 10-20% of drylands are subject to desertification
· Desertification exacerbates poverty, creates food and water insecurity and aggravates conflict
· Global cost of desertification: 42 billion USD annually
· Estimated cost of preventing it: 2.4 billion USD
Drivers of Desertification
· Poor understanding of dryland ecology
· Low consultation with dryland resource managers
· Weak tenure arrangements and governance
· Unsupportive policies and investments
· Weak implementation of favourable policies
· Human poverty and changing population dynamics
· Climate change and climatic uncertainty
· Fragmentation of landscapes
