urban gardens is a reality with multiple benefits, not just food. If on the one hand it allows to have food at zero kilometer, healthier than that of the industrial supply chain, it also offers a precious moment of social cohesion, constituting a moment of activity and aggregation as an alternative to television and sofa.
Over the years, several projects have been developed in this sense, all aimed at combining energy efficiency with production efficiency. In this case we want to present the Impact Farm project by the Human Habitat laboratory.
The Danes Mikkel Kjaer and Ronnie Markussen have developed a compact and efficient greenhouse, based on hydroponics, characterized by the absence of land. The plants are anchored to an inert substrate (like clay) and nourished with water and organic nutrient solutions. There are many advantages, including the saving of water (90% less than traditional crops) and making the use of herbicides and pesticides almost useless.
Each Impact Farm offers 163 square meters available for growing, developed with a lightweight design that can be easily moved. In fact, its strength lies in its mobility: the greenhouse is available as a complete kit, which can be installed and started within just 10 days.
Once fully operational, the greenhouse can produce 3 to 6 tons of food a year, with self-sufficiency even at an energy level thanks to the solar panels installed on the roof.
The idea of the designers was to create a model of food development different from the large-scale distribution, which employed forces on the territory and allowed to consume (or sell) products locally. Through Impact Farm the people of the big cities could come back to connect with what they eat, restoring value and dignity to the agricultural product and feeding the cohesion of the social fabric.
