SEN4LDN National Demonstration Products on Land Degradation Neutrality Indicator SDG15.3.1

This dataset contains the National Demonstration products that were generated within the ESA SEN4LDN project: "High resolution Land Degradation Neutrality Monitoring" for the integrated SDG15.3.1 indicator on Land Degradation Neutrality over Colombia, Portugal and Uganda.

The SEN4LDN national demonstration products consist of a series of output products on the three sub-indicators of land degradation as defined by the UNCCD – trends in land cover, trends in land productivity, and trends in carbon stocks – and a combined integrated LDN indicator. The outputs of the trends in land cover and trends in land productivity sub-indicators are integrated to generate a product that allows to calculate the extent of land degradation for reporting on UN SDG indicator 15.3.1, expressed as the proportion (percentage) of land that is degraded over total land area. This database contains the result of the so-called one-out-all-out in which a significant reduction or negative change in any one of the sub-indicators is considered to comprise land degradation.

The dataset includes the Land Degradation Neutrality indicator 2018-2023, with file naming LD_<country>_2018-2023.zip.

Products are distributed as 3x3° tiles with 1/12000° resolution (~10m) in Cloud Optimized Geotiff format. More information on product format and content can be found in the Product User Guide, available on the SEN4LDN Deliverables web page.

The SEN4LDN project aimed to develop, demonstrate and validate a robust and scientifically-sound EO methodology that exploits the high frequency and spatial resolution of open and free-of-charge satellite imagery to increase the spatial details of national assessments of land degradation and restoration, and provide synoptic information for countries to plan LDN interventions at appropriate scales.
