In the past, much of the food for a city came from its surrounding region. In many
countries, however, local supply has been replaced by national and international food
distribution systems. An Eco-City project to encourage use of locally produced food
could reduce the energy use and pollution of long-distance transportation. It would have
two other benefits: fresher food for urban residents and higher incomes for local
farmers. If such a project included heritage crops and meats, it could help maintain
agricultural biodiversity. Development of urban gardens is another way to provide city
residents with fresh food, as well an enjoyable pastime.
