The UN Food and Agriculture Organization reports that only 800 million people around the globe grow their own fruits or vegetables, or raise animals in cities, accounting for 15-20 percent of world’s food production.
Urban farming has recently gained renewed attention for its social, health, environmental, and economic benefits.
It can help farmers and consumers
- Save money
- Increase year-round fresh food access
- Promote healthy lifestyles in urban settings.
It also gives people more control over the production of the food they eat, which has benefits like reducing the use of harmful pesticides.
Urban Farming is pushing the limits of innovation, using technology and controlled environments that allow them grow food all year-round while avoiding challenges like erratic weather patterns, pests, and disease. Some of these enterprises are sustainably meeting year-round food needs for people living in cities.
Dickson Despommier, a professor of environmental health sciences at Columbia University, has proposed “vertical farming”: growing food—including fish and poultry—in urban buildings as tall as 30 stories and covering a city block. In his vision, you could eliminate the need for soil by growing plants hydroponically (in a liquid) or aeroponically (in the air). You’d reduce water use and end runoff by recycling water in a closed irrigation system. Transportation costs would be next to nil.
