FAZENDA URBANAA system of aquaponics urban farms on the rooftops of São Paulo

The Urban Farm grows vegetables using aquaponics, which reuses water from the tanks where tilapia fish are grown (and where fish waste is used to enrich plants). The whole process is carried out without the use of agrochemicals. The water supply for the tanks is collected from the rain. As a result, distances between producers and consumers are shortened, and local communities are mobilised to work together.
