Urban farming can conjure up images of small plots of land in the midst of concrete jungles — oases where city-dwellers can come together, forge bonds with neighbors and reconnect with nature.

Yet, urban farming is an opportunity to bring large-scale food production into cities, taking advantage of new technologies and innovation to address issues of sustainability and resilience in the food system that are being exacerbated by climate change and political instability.

“Growing food in urban areas gives people the opportunity to transform their relationship with consumption by becoming producers themselves,” says Kai Sawyer, founder of Tokyo Urban Permaculture, a project he started in 2011 with the mission of promoting a holistic approach to land management and settlement design.
