The Land Degradation Assessment in Drylands project (LADA) aims at informed policy advice on
land degradation at global, national and local level through the assessment of land degradation
at different spatial and temporal scales and the creation of a baseline at global level for future
monitoring. DISforLADA is a Land Degradation Assessment Indicator system developed by FAO
and the LADA partners.

The VS-Fast methodology describes and evaluates the morphological conditions of soils in the
feld. This is a more rapid and immediate method of soil assessment than the conventional sets
of soil physical measurements commonly used. Emphasis with VS-Fast is the assessment, both
tactile/qualifed and quantifed, of soil physical condition (soil structure units and porosity) as well as
soil colour, root development, soil fauna, slaking and dispersion, organic matter status and water
infltration.

RUSLE2 can be applied to any land (including cropland) where mineral soil is exposed to the direct
forces of waterdrop impact and surface runoff generated by rainfall intensity being greater than the
infltration rate of water into the soil. RUSLE2 estimates rates of rill and interrill soil erosion caused
by rainfall and its associated overland fow. The four major factors of climate, soil, topography, and
land use determine rates of rill and interrill erosion. A RUSLE2 user applies RUSLE2 to a specifc site
by describing feld conditions at the site for these four factors. RUSLE2 uses this feld description to
compute erosion estimates.
