“Siena: urban agriculture
In the future, wars will be fought over water, not oil, and they will be fought within cities.
My proposal is to develop a hydroponic garden on the rooftop of a private site in the city of Siena. This project focuses on the concept of self-sufficiency and private space. It is a small-scale project that can make use of local, prefabricated, and recyclable materials.
Hydroponic gardens do not require soil. A rooftop garden can provide its owner with both vegetables and rainwater, which can also be collected from other rooftops—a method traditionally used in Mediterranean cities. The water, stored in tanks, can be used for non-potable purposes, thus offering the owner a dual water system.
The World Bank recommends developing urban agriculture for growing cities like Cairo. This system is already being implemented in Caracas. A month ago, while walking through the streets of Siena and San Gimignano, I had the impression that the weight of history is sinking these cities; with the urban agriculture project, I would like to bring to the fore the problems, lifestyles and needs of the contemporary city in the context of Siena.”
