Proportion of degraded land relative to total land area
- Global
- National
Land degradation extent for reporting on SDG indicator 15.3.1 is calculated using its three sub-indicators, which are:
- Land coverage trends.
- Land productivity trends
- Carbon stock trends (above and below ground), currently represented by soil organic carbon (SOC) stocks.
The degradation analysis results for each of the sub-indicators are integrated using a so-called ¿one-out, all-out¿ method, where a significant reduction or negative change in any of the three sub-indicators is considered to be land degradation, regardless of how the other two sub-indicators fare.
Administrative data that do not correspond to any statistics of the National Statistical Plan It must be reported every 4 years beginning in 2018. In the National Report 2018 the default data provided for Spain by the UNCCD has been used, once its consistency with the own evaluation (in development) has been verified for its determination with the data of the country.
