A global land-use data cube 1992-2020 based on the Human Appropriation of Net Primary Production: Dataset 3

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 (HANPP_luc), the harvested NPP (including losses, HANPP_harv), and the NPP remaining in ecosystems after harvest (NPP_eco) 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 HANPP_harv to NPP_eco results in the actual NPP available before harvest (NPP_act=NPP_eco+HANPP_harv), and adding HANPP_luc to NPP_act results in the potential NPP available in the hypothetical absence of land use (NPP_pot=NPP_act+HANPP_luc) 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 NPP_pot can be calculated by summing up HANPP_harv and HANPP_luc and dividing it by NPP_pot. 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: grazing land with (almost) no trees (GL-notrees); cropland used for production of other fibres (CL-OFIB); fallow cropland areas (CL-FALL)
