650.000 km2 of degrading land is not suitable for agriculture
Around 90.000 km2 is farmed nonetheless and should not be
Who is degrading the rest and why?
290.000 km2 is farmed and degrading, half of it on poor soils
Overall, most of the degrading land has below average population density
Suggesting encroachment on fragile lands
very productive land is endangered
250.000 km2 of grassland is degrading, despite greening of Sahel
Overall, 60 million people live on land that is degrading
At the current rate of degradation 10%/20 years,
this century will see some serious conflicts over land resources

Identify those agricultural regions where conditions are so unfavourable
Identify areas where population pressure is high and degradation is in full progress.
Every effort should be made to introduce sustainable farming practises in such areas.
Identify areas where pastoralist and farmers are exerting undue pressure on land that is
intrinsically favourable for their use. These are areas of degradation of prime land where
research should be undertaken.
Locate those regions where farmers are encroaching or have occupied marginal land or
where uncontrolled deforestation is taking place. Here, proper institutions should be put in
place to ensure that these processes do not damage the ecosystem services on which
societies depend.
