Community Gardens

Community gardens and City Farms are not just about changing climate back. They are about adapting to changing climate in such a way that could be exemplary even after climate consolidated. http://www.placemark.com.au/community-gardens.html
Why you ask? Because the loss of agricultural land is already a reality as well as genetically tempered produce that is out of public control (in part because companies make the the production "blue-print" commercially confidential.)

Add to it that we may start assigning increasing amount of land to growing crops for burning it as fuel just to get from A to B (that is for bio-ethanol or bio-fuel.) That takes them out of the zero sum game, that is the amount of land available globally for agricultural produce. As a result, the intensity with which the public will require clean and controlled production of food produce (and possible hobby plants and cut flowers that are not toxic or contaminated) may in turn increase dramatically - no matter what.

The extending drought and the shortage of irrigation water bringing these gardens to life and making them ever more popular. My hunch is that as they will grow in size they will inevitably specialize. But until then I would like to see them managed for growth or just simply better managed in the face of inherent conflicts of interest implicit in running many of them.
