Foodshed
The “farm-to-table” movement is focused on producing food locally within a foodshed, and delivering it to local consumers. Direct farm-to-table in the United States tends to comprise only a very minor segment of the food distribution system in terms of size and importance, but is growing in popularity.Nearly 5 percent of all farmers engage in some form of direct food marketing. Estimates of all farm-to-table sales within a foodshed range from roughly $550 million to $2 billion. Many local farms are family-run farms that are successful and do survive through poor economic conditions. Ecologists consider to be more adaptive and more likely to “reproduce” in highly variable and uncertain environments.
Vertical farming
Dickson Despommier is a professor of environmental health sciences and microbiology. He reopened the topic of VF in 1999 with graduate students in a medical ecology class. He speculated that a 30-floor farm on one city block could provide food for 50,000 people including vegetables, fruit, eggs and meat, explaining that hydroponic crops could be grown on upper floors; while the lower floors would be suited for chickens and fish that eat plant waste.
