Data on SDG Indicator 15.3.1 are regularly collected by the UNCCD through its national reporting and review process since 2018, and every four years thereafter.
Data underpinning the indicator and its sub-indicators are mainly derived from Earth Observation data sources which have global coverage and can be disaggregated to the national level.
Through the UNCCD reporting and review process, countries receive default national estimates of land degradation and its sub-indicators derived from global data sources. The provision of default data is aimed at facilitating national reporting and meeting a perceived data capacity gap. Countries are given the opportunity as well as tools necessary to interpret and verify national estimates derived from global data sources and, eventually, replace them with other national data.
During the 2018 UNCCD reporting process, the sources of default data were:
- European Space Agency’s Climate Change Initiative Land Cover dataset which provides consistent global land cover maps at 300 m spatial resolution on an annual basis from 1992 to 2015
- Joint Research Centre's Land Productivity Dynamics (LPD) dataset which provides consistent global LPD maps at 1km spatial resolution covering the period 1999 to 2013
- ISRIC's SoilGrids250m which was used to derive soil organic carbon average (ton/ha) to 30 cm
