Excellent summary of permaculture as a social movement, including a multi layered definition of permaculture in theory/practice as well as analyses of its political positions in theory/practice.
Becomes essential reading for anyone interested in social movements and particularly environmental action.
Even if many, like myself, would not expect much from permaculture politically, this book provides a good summary of what is being done and what isn't and why.
The successes and failures of permaculture are also essential to consider for any of us who realize the necessity of system change - and the difficulties in the process.
In terms of accessibility, I give it 4 out of 5, which is probably the highest score I could imagine on such topics.
