Urbanization and agriculture evolved together, but as cities grew, so did the distance between urban populations and the farms they depend on, increasing the risk of food insecurity and the cost and carbon footprint of every calorie.

Such dilemmas will likely intensify as urbanization advances, as two thirds of the global population are expected be urban by 2050, creating both challenges and opportunities.
