Street Farming

For all of you who are wondering how you can get started farming, right where you are, this weekend's NY Times Magazine has an excellent story about Will Allen's efforts to spread the practice of urban farming.

Like others in the so-called good-food movement, Allen, who is 60, asserts that our industrial food system is depleting soil, poisoning water, gobbling fossil fuels and stuffing us with bad calories. Like others, he advocates eating locally grown food. But to Allen, local doesn’t mean a rolling pasture or even a suburban garden: it means 14 greenhouses crammed onto two acres in a working-class neighborhood on Milwaukee’s northwest side, less than half a mile from the city’s largest public-housing project.

And this is why Allen is so fond of his worms. When you’re producing a quarter of a million dollars’ worth of food in such a small space, soil fertility is everything. Without microbe- and nutrient-rich worm castings (poop, that is), Allen’s Growing Power farm couldn’t provide healthful food to 10,000 urbanites — through his on-farm retail store, in schools and restaurants, at farmers’ markets and in low-cost market baskets delivered to neighborhood pickup points. He couldn’t employ scores of people, some from the nearby housing project; continually train farmers in intensive polyculture; or convert millions of pounds of food waste into a version of black gold.

With seeds planted at quadruple density and nearly every inch of space maximized to generate exceptional bounty, Growing Power is an agricultural Mumbai, a supercity of upward-thrusting tendrils and duct-taped infrastructure. Allen pointed to five tiers of planters brimming with salad greens. “We’re growing in 25,000 pots,” he said. Ducking his 6-foot-7 frame under one of them, he pussyfooted down a leaf-crammed aisle. “We grow a thousand trays of sprouts a week; every square foot brings in $30.” He headed toward the in-ground fish tanks stocked with tens of thousands of tilapia and perch. Pumps send the dirty fish water up into beds of watercress, which filter pollutants and trickle the cleaner water back down to the fish — a symbiotic system called aquaponics. The watercress sells for $16 a pound; the fish fetch $6 apiece.

Today Allen is the go-to expert on urban farming, and there is a hunger for his knowledge. When I visited Growing Power, Allen was conducting a two-day
workshop for 40 people: each paid $325 to learn worm composting, aquaponics construction and other farm skills. “We need 50 million more people growing food,” Allen told them, “on porches, in pots, in side yards.” The reasons are simple: as oil prices rise, cities expand and housing developments replace farmland, the ability to grow more food in less space becomes ever more important. As Allen can’t help reminding us, with a mischievous smile, “Chicago has 77,000 vacant lots.”

Just imagine if we could get something similar going in Detroit. I don't think it's even possible to count the number of vacant lots there...
