## LUH2 Transient Land Use and Land Cover Change Dataset

The article discusses the LUH2 (Land Use Harmonized version 2) transient datasets, which were produced to coordinate the processing and consistency of land use and land cover change (LULCC) data between the historical period (1850-2015) and future SSP-RCP scenarios (2016-2100).

Key points:

### Historical Data (1850-2015)
- Based on HYDE 3.2 for agriculture and urban land use, and FAO, Landsat, and other sources for wood harvest.
- Includes fractional grid cell coverage of 12 land units (e.g. primary/secondary forest, pasture, crops, etc.)

### Future Scenarios (2015-2100)
- Referred to as the LUH2 Future Scenario datasets, aligned with SSP-RCP scenarios.
- Provides more detailed land unit information compared to CMIP5 datasets, including forest/non-forest, pasture/rangeland, and crop types.
- Includes transition matrices describing annual land cover changes (gross and net LULCC).
- Also provides harmonized prescriptions for wood harvest, nitrogen fertilization, and irrigation.

The LUH2 datasets aim to improve the consistency and detail of LULCC information for use in Earth System Model simulations as part of the CMIP6 project.
