Aquaponics and other indoor ag systems rely on access to water and energy, not soil or seas. Siting them near existing distribution hubs or industrial parks makes plenty of sense.
The story that indoor farming could potentially produce dramatic environmental gains is largely fictional today, but innovators are working to bring truth to the tale in a not-so-distant future.
From high-tech indoor farms in France and Singapore to mobile apps connecting urban growers and eaters in India and the United States, here are more than a dozen initiatives using tech, entrepreneurship, and social innovation to change urban agriculture.
Cuba offers interesting lessons for how to develop urban agriculture, including government-allocated land and agroecological methods that deliver high yields and diverse crops in small spaces.
