Urban agriculture is the practice of cultivating, processing, and distributing food in or around a village, town, or city. Urban agriculture can also involve animal husbandry, aquaculture, agroforestry, and horticulture. These activities also occur in peri-urban areas as well. Urban farming is generally practiced for income-earning or food-producing activities, though in some communities the main impetus is recreation and relaxation. Urban agriculture contributes to food security and food safety in two ways: first, it increases the amount of food available to people living in cities, and second, it allows fresh vegetables, fruits, and meat products to be made available to urban consumers. It decreases food deserts. A common and efficient form of urban agriculture is the biointensive method. Because urban agriculture promotes energy-saving local food production, urban and peri-urban agriculture are generally seen as sustainable agriculture. Another aspect of urban farming, especially in densely populated American cities, is the use of grow-bags to raise a wide range of crops. Many apartment dwellers with no yards to speak of, or people with very small yards, will set up these bags on a balcony or thin strip of land. Also, many types of hanging bags are available to plant, expanding the area available for planting. The bags themselves are made from a variety of materials, including canvas, weed barrier fabric, and polyester, all having semi-porous properties so the soil can drain adequately. The term "Bagriculture" was coined in 1998 by Los Angeles animator and amateur archaeologist Rudy Zappa Martinez to describe this type of agriculture. (via Freebase)
