Mapping land degradation is complex, especially at large spatial scales. The impacts on ecosystem services, as well as the drivers and processes involved, are highly diverse and change over time. Social perceptions of the severity and effects of degradation also vary, making it difficult to create a single map that addresses all views and needs. Nevertheless, mapping and quantifying land degradation is essential to identify hotspots, plan strategic interventions, and monitor progress towards Land Degradation Neutrality (LDN) at landscape scale.
Using cloud computing, WOCAT has co-developed user-friendly applications for both experts and non-experts that integrate global, national, and local information. These apps facilitate the integration of expert knowledge, support evidence-based decision-making and planning, and enable participatory mapping. By applying the principle of Convergence of Evidence, first introduced in the World Atlas of Desertification, WOCAT apps provide an accessible way to map land degradation. With just one click, users can explore a range of applications co-developed with institutions and countries worldwide.
