‘Machine For Living Independently’

The plants, worms and bacteria living in this sculpture rely on each other and on human participation. They are fed entirely on waste generated by us: coffee grounds and veggie scraps from our kitchen, old newspapers and shredded junk mail from our offices, and carbon dioxide from our breath. They are watered by our rocking leisurely in the chair, which mechanically pushes water up to the top of the ecosystem and causes it to circulate through each part; delivering to the plant roots aerated water that has been fertilized by the worms living in the stream.

Urban agriculture already plays an important role in global food production, but can it keep cities fed?
A diversified urban food supply system, with food originating from a range of sources, might instead bolster a city’s resilience because it would be less sensitive to the impacts of climate change.

The findings of the Ouagadougou-Tamale study imply that achieving a sustainable, resilient urban food system is not a simple question of either local or global food supply chains; both are necessary. The more diverse urban food supply systems, the more resilient.
Local agricultural production needs to be considered in urban planning because most cities already are dependent on locally produced food. Overall, the extent of urban agriculture on a global scale warrants a reorientation of agricultural policies and development work, which are mostly focused on rural contexts.
