Urban agriculture won't resolve all food production and distribution problems, but it could take pressure off rural land while providing other advantages.

Humans are fast becoming city dwellers. According to the United Nations, "The urban population of the world has grown rapidly from 746 million in 1950 to 3.9 billion in 2014."

Sixty-six percent of us will likely live in urban environments by 2050. The number of mega-cities (more than 10 million inhabitants) is also skyrocketing, from 10 in 1990 to 28 in 2014—home to more than 453 million people—and is expected to grow to 41 by 2030.

Along with concerns about climate change and the distances much of our food travels from farm to plate, that's spurred a renewed interest in producing food where people live. Urban agriculture won't resolve all food production and distribution problems, but it could help take pressure off rural land while providing other advantages. From balcony, backyard, rooftop, indoor and community gardens to city beehives and chicken coops to larger urban farms and farmers markets, growing and distributing local food in or near cities is a healthy way to help the environment.
