What are planetary boundaries?Show answer
The planetary boundaries framework (Stockholm Resilience Centre, originally proposed by Rockstrom and colleagues, 2009; updated subsequently) identifies a set of Earth-system processes within which humanity can operate safely. The framework identifies nine boundaries including climate change, biosphere integrity, biogeochemical flows (nitrogen and phosphorus), land-system change, freshwater use, ocean acidification, stratospheric ozone, atmospheric aerosols, and novel entities (chemical pollution and plastics). Several boundaries are assessed by Stockholm Resilience Centre as transgressed.
