From vacant lots to vertical "pinkhouses," urban farmers are scouring cities for spaces to grow food. But their options vary widely from place to place.
While farmers in post-industrial cities like Detroit and Cleveland are claiming unused land for cultivation, in New York and Chicago, land comes at a high premium. That's why farmers there are increasingly eyeing spaces that they might not have to wrestle from developers: rooftops that are already green.
When critics of industrial agriculture complain that today's food production is too big and too dependent on pesticides, that it damages the environment and delivers mediocre food, there's a line that farmers offer in response: We're feeding the world.
It's high-tech agriculture's claim to the moral high ground. Farmers say they farm the way they do to produce food as efficiently as possible to feed the world.
John Mabry, an animal science professor at Iowa State University, has a grant from the National Pork Board to study nutrition in Berkshire hogs.
When a new disease — known as PEDV —turned up in the U.S. hog industry in May and threatened to kill whole litters of piglets, the National Pork Board quickly responded with $450,000 in research funding.
