A global land-use data cube 1992-2020 based on the Human Appropriation of Net Primary Production: Dataset 10

This dataset is part of the LUIcube, a global dataset on land-use at 30 arcsecond spatial resolution. The LUIcube includes information on area, the change in NPP due to land conversions (HANPPluc), the harvested NPP (including losses, HANPPharv), and the NPP remaining in ecosystems after harvest (NPPeco) for 32 land-use classes in annual time-steps from 1992 to 2020. A detailed description of the LUIcube is available in the accompanying publication.

The layers of land-use areas are provided in square kilometers (km²) per grid cell. All NPP flows are provided in tC/yr per grid cell. Adding HANPPharv to NPPeco results in the actual NPP available before harvest (NPPact=NPPeco+HANPPharv), and adding HANPPluc to NPPact results in the potential NPP available in the hypothetical absence of land use (NPPpot=NPPact+HANPPluc) for the given land-use class. Area-intensive values (in gC/m²/yr) can be calculated by dividing the NPP flows by the area of the respective land-use class per grid cell. HANPP in % of NPPpot can be calculated by summing up HANPPharv and HANPPluc and dividing it by NPPpot. Areas and NPP flows of land-use classes can be aggregated to calculate their overall HANPP.

This Zenodo repository provides data on following land-use classes: 

1.      total forestry area (FO-total in HANPPharv.zip, NPPeco.zip, area.zip; HANPPluc is zero for forestry) including coniferous and non-coniferous forestry; total wilderness areas (WILD-total) including unused productive wilderness areas, productive wilderness areas that are sporadically used at very low intensity, and unused unproductive wilderness areas
