Urban Farming and the Triple Bottom Line

The sustainability of urban farming in term of economic, environmental, social, and cultural considerations.  From Vox:

"What emerges is a nuanced picture. Urban farming likely won't ever provide cities with all that many calories. And the environmental advantages are ... debatable. But urban farms can provide a bunch of other neat benefits, from bolstering local communities to (sometimes) encouraging healthier diets. They can also give city-dwellers a better appreciation of how our food system works, which is less nebulous than it sounds.

"We did find a lot of benefits to urban agriculture," Santo told me. "But you want to be careful not to overstate things. If urban agriculture gets sold as something that will create all these jobs or feed entire cities — and then it doesn't — it could quickly lose support.""
