A salad of ecosystem funtions
Food policies include meat-free days, school lunches, local procurement and regulation of restaurants. Agriculture near or in cities reduces the need for transport of food, cutting a city’s dependence on fossil fuels, and reducing emissions of CO2 and other air pollutants. When urban agriculture is combined with waste recycling, composting, and wastewater irrigation, cities are solving several problems at once. Today nearly 15% of the world’s food is supplied by urban farming, increasing cities’ resilience as well as providing employment and community building.
