UNCCD COP13 GEF Day: Innovation, Science and TechnologyCase study: LandPKS Mobile Apps for Optimizing LDN Investments
contact@landpotential.org
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

Simple changes – land use/LDN planning based on SOILS + TOPOGRAPHY + CLIIMATE
Sustainable crop production possible?Avoid ReduceReverse
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

1 app w/2 modules (download iPhone and
Android – everywhere*)
Note for our Chinese friends: using LandPKScurrently requires a Google account. We hope to eliminate this requirement by December.
LandInfo• Today: Describe soil,
topography, get information on climate, soil water holding capacity
• Dec 2017: automatically identify soil, topography climate
• 2018: links to site-specific knowledge and information including WOCAT
------- Pilot countries only in 2017 --------
Nzdl.org
2018
LandInfo for TARGETING and UPSCALING SLM
------- Pilot countries only in 2017 --------Soil/climate-specific fertilizer + management (pilot countries)

2018
Automated calculation/reporting (no internet required) + cloud storage- Dominant species
(est)- Bare ground- Crop residue
cover- Tree cover- Grass cover- % large gaps- Height- Plant density- Etc…
LandCover for MONITORING LDN
Data portal• Click on map/download
to spreadsheet/use API• Future tools will allow
local/global, comparisons, competition, additional visualization.
