Architects Antonio Girardi and Cristiana Favretto of StudioMobile in Treviso, Italy, have created a floating greenhouse named the Jellyfish Barge that produces enough food for two families without consuming land, fresh water or energy.
The architects were inspired by the World Bank prediction that the world population will grow to almost 10 billion in the next four decades. By 2050, the global demand for food is expected to be 60-70 percent higher than today. Scarcity of water and cultivable land are the main obstacles to meet the quantitative and qualitative shifts of the world’s demand. Agriculture is the human activity that relies most on the existing water resources, say the architects.
