We have created heat domes over our cities (concrete, bitumen and heat-absorbing, re-radiating surfaces). By providing more ‘solar panels’ (plants) in our cityscape, we can convert some of this heat into productive biomass and productive food systems (community gardens and rooftop gardens).
By 2050 there are an expected 10 billion people on the planet. Some 7 billion will be in cities with half of their food needing to come from innovative urban farming strategies.

WATER USE EFFICIENCY - WICKING BAGS
10 X WUE - LIMITING LOSSES AND COMPETITION
To help catalyse some direct practical action and outcomes, Regenerate Earth has designed and would like to make available wicking bags to everyone globally to aid their urban agriculture outcomes. Wicking bags are simple, cheap innovations made from locally recycled waste plastic to massively aid the opportunities for, efficiency of and production from urban agriculture.
While simple, cheap and highly flexible so as to be of service in diverse sites, the use of such wicking bags has the potential to fundamentally enhance the efficiency, ease, equity and value of most urban and village farming and food production systems. Given that some 80% of the food eaten by humanity already comes from such gardens often via the hard work of poor women, making this much easier, more secure and productive can contribute greatly to securing our future food needs.
