Paris food stock is highly dependent from the outside supply, food travels long distances before arriving at the capital. Furthermore Paris supply system is very centralized ( most of the food stock go through Rungis) and therefore not very resilient. In case of city blockade it is generally agreed that Paris will be out of food within three days. And this could happen sooner than  excepted. In her book Paris coule t-il ? published in 2012 Magali Reghezza-Zitt demonstrates how fast could Paris situation deteriorate in case of massive river flood. Part of the city would be completely isolated.

In this case rural farming could participate to the city emergency plan by creating close loops of vegetables supply, that could last for some time before solving the crisis situation.

Developing Urban farming could increase city resilience.
