  • Our buildings consume

  • about fourty percent of our energy.

  • And with our emissions threatening to permanently change our climate,

  • we need more efficient,

  • better, greener cities.

  • We can start by being smart with what we have:

  • passive solar buildings, public transit, private pedal power, high-density living and tele-working.

  • But our food production is still a long way from most of the people who live in the cities,

  • built on the best arable land. Vertical Farming could turn this on its head, or at

  • least its side. It would bring together a host of

  • emerging technologies by putting food production on the buildings we live and

  • work in.

  • To reduce land use,

  • cool our urban heat sinks,

  • and drastically reduce food transport costs.

  • Modern agriculture uses seventy percent of the world's available freshwater. But

  • Vertical Farms

  • could be fitted with 'nano-films' that boost condensation. And 'nano-membranes' would filter and clean recycled

  • water. Better water quality - less waste.

  • Crop effectiveness would be boosted by

  • genetic engineering to select the best

  • genetic variance for the environment.

  • Fiber optics

  • might provide light with incredible energy efficiency.

  • One square block farm thirty stories high, could

  • yield as much food

  • as ten square kilometers outdoors.

  • There are of course

  • hurdles. The crops best suited to Vertical Farming may require us to adjust our diets.

  • But would farmers and agribusiness take this lying down?

  • Or is it simply that our dollars are best spent on smart,

  • simple, and practical improvements to

  • existing infrastructure and technology.
