Future wars will be fought for water, not oil, and they will be fought in cities.

I propose to develop a hydroponic vegetable garden on top of a roof on a privately owned site in the city of Siena. The project focuses on notions of self-sustainability and private space. This is a small-scale project and can use local prefabricated and recyclable materials.

The structure is an addition to an existing building. Basically, it is a roof that collects rainwater. Other extensions are also possible in the form of horizontal and
vertical screens (for example, to protect against extreme temperatures during summer and winter).

Hydroponic gardens do not use soil. The garden on the roof supplies the owner of the roof with vegetables. Rainwater is harvested from the garden roof and can be tapped from other roofs as well (this is a traditional way of gathering water in
Mediterranean cities). The water, stored in containers, can be used for non-drinking purposes, thus providing the owner with a twin water system.

Context: The World Bank recommends the development of urban agriculture for fast-growing cities like Cairo. It is already implemented in Caracas. A month ago, when I was walking through the streets of Siena and San Gimignano, it seemed to me that history was weighing these cities down. With the urban agriculture project, I want to emphasize contemporary urban issues, lifestyles and needs in the context of Siena.
