5.1: Planetary Boundaries and the Anthropocene

The idea of 'planetary boundaries' and the new geological epoch of the 'Anthropocene' has captured the imagination of many policy makers and commentators and dominated discussions around the UN Sustainable Development Goals.

In this part of the module, Prof Melissa Leach (Director of the Institute of Development Studies (IDS) and former director of the STEPS Centre), articulates the problems with these concepts and how a STEPS pathways perspective might help to foreground issues of social justice and politics in these on-going international policy discussions.

Questions to guide reading
  1. On what basis do Rockström and his co-authors define planetary boundaries? How does the more recent version by Steffen et al (2015) (see additional reading, below) adapt the argument?
  2. On what basis does Raworth challenge Rockström et al’s planetary boundaries idea? What does she argue must be added?
  3. How do Leach et al take this further still via the application of a Pathways Approach?
