The nebulous notion of sustainability begs for visual representation.
From Brown’s book Leonardo’s Vision: A Guide to Collective Thinking and Action:
The potential for whole-of-community learning rests on a paradox. Any lasting change in any one community depends on matching transformation in the surrounding society. Any lasting change in the larger society depends upon transformational change in its constituent communities. …
The whole-of-community action web suggests six forms of connection are needed to hold communities together as they learn and change.
In the diagram, these six are: whole-of-community commitment, internal community integrity, inter-community partnerships, external community alliances, integrated forward planning, and future-directed action.
