Lately, whenever we’re surprised by new uses for common surfaces, it’s usually in the name of advertising.  For example, these days the simple act of opening an airplane tray table brings us face-to-face with an ad.

Now the reinvention of everyday surfaces is becoming the vanguard of sustainable food.  From suburban yards to warehouse rooftops to ocean waters, many overlooked places are the new “ground” for growth.

Last week at Agriculture 2.0, Bruce Kahn, Ph.D., of Deutsche Bank, stated that the world does not have enough productive land to feed the coming population boom.  According to Kahn, even if we improve the global land output to 90% productivity, the shortage will still exist.

A New Field?

David Tze, of Aquacopia, an investment firm for seafood farming, later responded that Mr. Kahn’s statistics didn’t account for food production in the world’s oceans.  Imagine if the sea were as prolific as the land in providing people with protein sources.  Another presenter, Norbert Sporns of HQ Sustainable Maritime Industires, Inc., underlined the immediacy of this point.  His company, a member of the American Stock Exchange, has a full line of packaged meals based on the fish tilapia, farmed using “zero toxins.”  According to the company website, “Total U.S. consumption of tilapia products has risen from less than $20 million in 1992 to nearly $560 million in 2007.”  Consumer demand – based on want, not yet need – is in full swing.

The Sky Vegetable System

The Sky Vegetable System

Back on land — where my heart resides — Sky Vegetables plans to grow city food on large scale rooftops.  The clean system runs on solar and wind power to energize its year-around hydroponic greenhouse.  Rain water collection barrels gather water for the crops.

This company corrects several big problems in our current food system:  It brings fresh produce to under-served, but eager, urban communities.  It does so by shortening the miles and gallons of gasoline needed to deliver good food.  As a closed-loop system, using clean and recycled water, it does not put pesticides or toxic run-off into the area.  Add in the benefits of a green roof for the host building and its energy savings from excess solar and wind production, and we have a growing system that I believe our children will know well.

Lastly, SPIN-Farming is radical in its simplicity.  Take the land you have and grow on it.  SPIN-Farming operates as a franchise, largely by providing learning materials for the SPIN system.  The good news is the cost of entry is very small: $100 bucks will get you started.  In the words of one of the company’s founders, Roxanne Christensen, SPIN “removes the two big barriers to entry for new farmers – land and capital.”  Now the future looks better for the annual block potluck party, too.

Note:  All companies mentioned here were participants in the conference, Agriculture 2.0 in New York City.

Last week, in one of the most densely populated places on Earth, 150 people addressed a topic usually left to pasture:  The future of agriculture.

At one point, Melina Shannon-DiPietro, Director of the Yale Sustainable Food Project, asked the audience, “How many of you have worked in a garden in the past month?”  Over three-quarters of the room raised our hands.

Shannon-DiPietro also said that Yale University currently offers 30 classes related to food and agriculture.  As recently as 2003, that number was zero.

What is happening here and why now?

The group in the NYC room was attending Agriculture 2.0:  The Conference for Innovators & Investors, hosted by NewSeed Advisors and SPIN-Farming.  There is much to explore, and for now, a few facts have percolated to the top:

  • Many estimate the world’s population will grow to 9 billion by 2050.  As a result, the Asset Management arm of Deutsche Bank foresees a 50% increase in global caloric demand.  We aren’t ready.
  • Every year, as the Mississippi River flows into the Gulf of Mexico, the agricultural run-off creates a vast “dead zone” in the water.  The dead zone can get as large as the state of Mississippi and nothing survives in it.
  • Tod Murphy of the Farmers Diner said that as Americans consume food carted from thousands of miles away, we eat about 19% of our country’s fossil fuel usage.  Robert Fireman of Sky Vegetables framed the issue another way:  Every year, the average American intakes 350 gallons of oil with his meals.

We have never had issues like these before in human history.

But innovators live in the solution.  We have also never been as connected and accessible to one another as we are now.  Thus, in the spirit of the pioneers at Agriculture 2.0, we have never had opportunities like this before.  More to come.
