Phys.org:

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?

    There was a time when a Farmer's Market excited me. Fresh, wholesome food, at less than wholesale prices - beautiful! In recent years, farmer's markets seem to be mostly ripoffs. The fresh food is sold at grocery store prices, no bulk sales or bulk discounts. There are mostly craft items available, at exorbitant prices, whether they be woolen goods, soaps, lotions, maybe cotton goods. And, baked goods. True, the baked goods are mostly better than anything the grocers sell, but they are priced right up there with the best of a grocer's offerings.

    The livestock auctions today meet my expectations of a farmer's market, more than a farmer's market does.

    Maybe that's just a local phenomenon. I can't really say, since I don't travel much anymore.

    The main advantage of farmer's markets is that because the farmer is the retailer, they get to keep much more of what you pay. Also, in really busy farmer's markets where there a whole bunch of farms selling the same stuff, you get market competition (sometimes even in real-time) keeping quality up and prices down.
