Objectives1. Review how an understating of land
potential can increase ROI on LDN2. Provide an introduction to the freely
available LandPKS mobile app– LandInfo module: soil inventory (now) and
identification (late 2017) for matching land use and restoration with its sustainable potential
– LandCover module: monitoring changes in land cover

Alternative livelihoods and agricultural intensification example100m
+ high wind erosion risk
Dark soil with mix of sand, silt, clay:successful crop production even during drought years AND no fertilizer required 1st year
Light sandy soil:successful crop onlyduring wet years (1/5) and manure always required
Land potential can vary at scales scales finer than mapped (e.g. N. Namibia -photos), and less in others (e.g. parts of Inner Mongolia uniformly sandy soils)

Success! Failure
Land potential = high restoration potential
(soil + topography + climate)
Land potential =low restoration
