Rooftop Gardens Project in Montreal

Since 2003, Alternatives has been promoting the recuperation of unused spaces such as rooftops, terraces and balconies for developing new productive green space. The goal is to create simple models of food production that are affordable, ecological, participative, and easily transferable to the global South as much as northern countries. This type of production is seen as a way to deal with increasing urbanization, pollution, and impoverishment of urban populations. It's a fusion of hydroponics, permaculture, organic agriculture, and community gardening.

Essentially we cultivate fruits and vegetables in containers of earth above water. This optimizes the growth of edible plants and ensures a constant flow of water and oxygen. The containers also serve to capture rain water, and their mobility and adaptability allow people to cultivate food in places where the soil has been contaminated.
