Shared Socioeconomic Pathways  

The Shared Socioeconomic Pathways (SSPs) are five socio-economic development scenarios that include global projections of wealth, population, education, technology and reliance on fossil fuels. 

SSP1: Sustainable development 

SSP2: Middle of the road development 

SSP3: Regional rivalry  

SSP4: Inequality  

SSP5: Fossil-fuelled development

Land-use harmonization (LUH2)

The Land-Use Harmonization (LUH2) project has produced a harmonized set of land-use scenarios that smoothly connects the historical reconstructions of land-use with the future projections in the format required for Earth System Models.

Read more about LUH2 in Harmonization of global land use change and management for the period 850–2100 (LUH2) for CMIP6 (Hurtt et all, 2020).
