Abstract
Most cities around the world rely on long distance food supply from remote areas to feed their residents, indicating low food self-sufficiency for urban areas. As a result, urban food supply systems tend to be highly vulnerable to natural hazards and pandemics, and also have larger environmental consequences such as a high carbon footprint and a high virtual water footprint. This chapter analyses Tokyo‘s vegetable food supply system to investigate the risks of existing urban food supply systems and their impact on the environment . It argues that strengthening local production and consumption would reduce the risk of the current self-sufficiency rate for food in Tokyo falling below 1%. More local production and consumption would also bring positive results for environmental indicators such as the carbon and virtual water footprints respectively.
