  • With a vision and a strategy the 21st century city will be green, a healthy place for all and will generate zero net pollution. This book offers a vision and a strategy. Productive urban landscapes have two huge challenges to address: CO2 emissions are projected to increase by two-thirds in the next 20 years, and as the global food production increases so does the number of people going hungry, with the number of urban hungry soaring.
