NAIROBI, Aug 9 2013 (IPS) - Tucked deep in Kenya’s sprawling Kibera slum is the shanty that Alice Atieno calls home. It is just one among many small, badly-lit shacks built close together in this crowded slum where an estimated one million people live on about 400 hectares.
But right on her doorstep stalks of green leafy vegetables grow in soil-filled sacks. For the mother of six, these kale plants are the source of her livelihood.

From the Sky with Vegetables. Globe / Hedron a Rooftop Farm.
GLOBE / HEDRON is a bamboo greenhouse designed to organically grow fish and vegetables on top of generic flat roofs. The design is optimized for aquaponic farming techniques: the fish’s water nourishes the plants and plants clean the water for the fish.
Using this farming technique, GLOBE / HEDRON is optimized to feed four families of four all year round.
GLOBE / HEDRON is designed to be manufactured and retailed at a low cost. Easy-to-set-up units can be combined to scale up food production capacity.
Using a geodesic dome, the load of the fish tank rests on the frame of the greenhouse and is redistributed to a larger surface. Because of this design, the aquaponic farm can be housed on more roofs without any structural building adaptation. The dome structure is designed to be built with bamboo, so that it is biodegradable and organically farmed.
GLOBE / HEDRON is designed by Antonio Scarponi / Conceptual Devices in collabora…

Not only does it add plant nutrients and beneficial microorganisms to y…
