EStà has been the technical and scientific support in the project “Milan Food Policy” signed by Milan municipality and Fondazione Cariplo (01/07/2014 – 30/06/2019) with the aim to develop a Urban Food Policy. Addressing food as a key to the sustainability of the city means reading and governing the relationships that link Milan to cities and territories in the global economy, starting from the aspects of physical proximity and the organization of social and economic relations in the Milan and Lombardy area. The city is seen as a complex organism, a highly dependent-on-the-outside ecosystem that inputs energy, water, soil and food and outputs discards, waste, emissions. Improving the management of input and output of substances and energy in urban areas has significant and systemic effects both locally and globally.
