Anticipation

Socio-economic drivers are typically informed by a scenario narrative that in qualitative terms describes the overall logic behind the scenarios. In the case of WITCH, the Shared Socio-economic Pathways (SSPs, see O’Neill et al., 2014) provide this overall scenario logic based on which the main socio-economic drivers, population and GDP, have been quantified. The subsections of this chapter describe how these quantitative drivers are used in WITCH.
