Implementing SSPs in CLUMondo (2017)

Using a previous model configuration, specific adjustments were made according to SSP narratives. The projected demand for crop production, bovines, goats and sheep and urban area were provided by IMAGE, as were the exogenous productivity increase factors due to technological change, per year.

For SSP1 demands were included for tons of crop production, head of bovines, goats and sheep (corrected to a ‘livestock unit’), builtup area and tons of carbon. The carbon demand was based on a no net loss situation where the total carbon content of all land systems was not allowed to fall below 2000 levels. For SSP2 and SSP3 demands were included for tons of crop production, head of bovines, goats and sheep (corrected to a ‘livestock unit’) and builtup area.
