Progress on the SSPs

The joint work with IIASA’s Energy Program on the Shared Socioeconomic Pathways (SSPs) was completed at the beginning of 2013 and all the data was made available in the SSP Database on the IIASA website.

Shared Socioeconomic Pathways (SSPs)

Shared Socioeconomic Pathways (SSPs)

The Shared Socioeconomic Pathways (SSPs), which describe alternative future worlds with respect to social and economic mitigation and adaptation challenges, are based on the population projections developed by the World Population Program (POP).  

POP worked with the Energy (ENE) and Environmental Services and Management  (ESM) programs on the SSPs.

The related data and analysis were presented at the numerous expert meetings and scientific conferences. The dedicated scientific paper was submitted to the journal, Global Environment Change, and is currently under review.

In addition, a review paper was accepted by the journal, Population and Environment, to be published in March 2014.

Figure 1. The three SSP scenarios shown above depict vastly different worlds. SSP1 envisages a rapidly developing world with more education, lower mortality, and a more rapid fertility decline in high fertility countries. SSP2 is considered the most likely in terms of future fertility, mortality, migration, and education. SSP3 assumes increasing global inequality with social and economic stagnation, with stagnant school enrolments and retarded demographic transition.
