What is the future of population and climate change research, and how can this research impact international policy? In a special issue of Population and Environment, environmental and social scientists look at these questions. “One of the most exciting developments in the climate change research community at present is the development of a new generation of climate scenarios,” write Adrian C. Hayes and Susana B. Adamo in the introduction. These can help facilitate more interdisciplinary research.

Lori Hunter and Brian O’Neill, for example, discuss “shared socio-economic pathways” (SSPs), a new framework that expands on the IPCC’s Special Report on Emissions Scenarios and combines demographic, socio-economic, and environmental models to identify gaps in population-environment research and to pose “plausible alternative trends in the evolution of social and natural systems over the twenty-first century.”

The five core representative pathways outlined are 1) sustainability, in which the world shifts gradually but dramatically toward a more sustainable path; 2) middle of the road, in which global population growth is moderate and development and income growth proceeds unevenly; 3) fragmentation, in which countries increasingly focus on domestic issues instead of broader-based development; 4) inequality, in which vulnerable groups have little representation in national and global institutions, and the world is regularly in social conflict; and 5) conventional development, where the world continues to be driven by the economic success of industrialized economies and adopts energy-intensive lifestyles. The authors emphasize that the SSP framework is open for further revision, and that researchers must continue to study and develop them. Click here to continue reading.
