"Thanks to the large cultivated areas that still surround it, Milan could truly become the first metropolis where agriculture returns to being the lifeblood of the city and not just an extraneous presence. But we need pluralistic agriculture, promoted by pluralistic urban policies. We need a new belt of extensive agriculture that could redraw the city's perimeter and prevent any further expansion; but we also need “zero-kilometre agriculture” to give meaning to the thousands of small pockets of empty space that dot the large sprawling city of northern Milan. Finally, we need urban agriculture to multiply the amount of green and organic space on rooftops and along roadsides and to create opportunities for employment and environmental awareness everywhere."
