Urban farming has grown by more than 30 percent in the United States in the past 30 years. Although it has been estimated that urban agriculture can meet 15 to 20 percent of global food demand, it remains to be seen what level of food self-sufficiency it can realistically ensure for cities.

One recent survey found that 51 countries do not have enough urban area to meet a recommended nutritional target of 300 grams per person per day of fresh vegetables. Moreover, it estimated, urban agriculture would require 30 percent of the total urban area of those countries to meet global demand for vegetables. Land tenure issues and urban sprawl could make it hard to free up this much land for food production.

Is urban farming a pipe dream, or can appropriating vacant lots for traditional farming or employing hydroponics make it work?

    ... to the traditional method of sterilizing not just the substrate, but the entire interior of the Mushroom Shed.

    Back in the heady days of yore, the coast of California between Santa Cruz and San Francisco had lots of mushroom sheds, but there's only one left now, I think unused.

    My father told me that one would place buckets of sulfuric acid down the aisle in the middle between the beds. Is there a Chemist in the house? Can you see where I am going with this?

    Then you walk to the back of the shed with a bunch of paper sacks full of Potassium Ferrocyanide. Perhaps realization is dawning upon you sorry lot.

    Drop the sacks in the bucks as you run like Hell down the aisle, out the door, slam it shut then bolt it for a few days.

    That just had to rock to work as a mushroom farmer. Not.
