Desertification problem in western Rajasthan, as caused by accelerated
and natural processes and manifested through degraded features like s
and sheets, drifting sand, active dunes, deflation hollows, rills, gul
lies, soil crust, salt encrustations, impeded drainage conditions, poo
r vegetation cover, low plant density and low biomass production under
different rainfall zones, has been highlighted in this paper. In the
less than 300 mm rainfall zone, wind erosion/deposition, salinisation
and waterlogging are the dominant processes of desertification. In the
more than 300 mm rainfall zone, water erosion and wind deposition are
the major processes leading to degradation of the croplands and grazi
ng lands.
