Historical land-use (LU) changes for the time period 1860-2018.
This data set provides land use categories, pastures and rangeland, 5 crop types (C3 annual, C3 perennial, C4 annual, C4 perennial and C3 nitrogen fixing crops). Furthermore, the LUH2 v2h data set gives information on management, i.e. it provides information of irrigated vs rainfed areas and on fertilization rates. We interpolated this data set onto the ISIMIP standard grid in order to generate the “landuse-totals”, the “landuse-pastures”, the “landuse-urbanareas” and the “n-fertilizer-5crops” ISIMIP input files.
Downscaling to 15 crops: The C4 perennial crops are not further downscaled from the "5 crops" data set and currently only include sugarcane. Similarly, the C3 perennial crops are not downscaled either. The data is derived from the "5 crops" LUH2 data, and the crops have been downscaled to 15 crops according to the ratios given by the Monfreda data set (Monfreda, Ramankutty, & Foley, 2008).
Based on the HYDE 3.2 data set (Klein Goldewijk, 2016), but harmonized by Hurtt et al. (LUH2 v2h data set, see Hurtt, Chini, Sahajpal, Frolking, & et al, in prep., see also https://luh.umd.edu).

For ISIMIP participants, these files are available for download on the DKRZ server using the path /ISIMIP/ISIMIP3a/InputData/socioeconomic/landuse/.
For external users, these data will be made available on the ISIMIP ESGF server (https://esg.pik-potsdam.de/projects/isimip/). Currently they are available via an rsync facility (described here: https://www.isimip.org/gettingstarted/data-access/#for-external-non-participant-users), for which the password will be provided upon request (firstname.lastname@example.org).
