THREAD: Understanding pivot. Growing pressure from world population life-style will reach a point where it is damaging the capacity of Earth systems to an extent where life support will be challenged. It is simply a question of at what stage governments act. 1/X

Pivot is the same at each point 1-4. I use the STOP acronym. a) Stop, or halt, all increase of extraction/drawdown. b) Think, plan measures that will restore Earth system capacity and keep delivering basic services. c) Organise, re-work old regulations and agencies and then 2/x

Proceed to act. Notice that pivots are different depending on where measures are set in. It is MUCH harder to change when carrying capacity is challenged to an extent where people are dying. However, the pivot idea is a useful decision framework as you will see in 3/x

Pivot planning will be informed by three different criteria:
-which societal services and Earth systems are involved?
-how well is the societal system performing now?
-what drawdown stage has been reached? For example: 4/x

Water: FAO identify five levels of water extraction stress. Measures introduced in the light green countries will be far different than those in high stress areas. That is one dimension for pivot but not sufficient. The other level is societal performance. 5/x
