2019 marks 10 years since the first publication of the 'planetary boundaries' concept in the scientific literature.
The Planetary Boundaries concept identifies nine global priorities relating to human-induced changes to the environment. The science shows that these nine processes and systems regulate the stability and resilience of the Earth System — the interactions of land, ocean, atmosphere and life that together provide conditions upon which our societies depend. Four of nine planetary boundaries have now been crossed as a result of human activity: climate change, loss of biosphere integrity, land-system change, altered biogeochemical cycles (phosphorus and nitrogen). Two of these, climate change and biosphere integrity, are what the scientists call "core boundaries". Significantly altering either of these core boundaries would drive the Earth System into a new state.Like the concept of the Anthropocene, the Planetary Boundaries is a concept underpinned by decades of work in the emerging field of Earth System science.
Over the last 2 years environmental educators in the ACT have been lucky enough to be able to meet up on a semi-regular basis with one of the field's most innovative, well regarded - and approachable - Earth System scientists, Canberra-based Professor Will Steffen.
It turns out that there is a good chance that in Canberra there is a sufficient critical mass of interest and capacity to develop some high quality secondary and primary teaching materials based on these concepts, with work starting on just that in late 2019. If that sounds interesting to you just let AAEE know at aaeeact@gmail.com If you are on facebook, why not join the AAEE Earth System Science and Planetary Boundaries Special Interest Group here.
