The design of an urban hydroponicum: an urban agriculture facility that remediates polluted storm water by utilizing biomimetic processes, that enables vast amounts of food to be grown

This treatise is founded in a belief that urban ecosystems should not be separate from natural ones and seeks to find ways in which existing urban systems can be reintegrated. This reintegration will be two-fold, providing a remedy for ecologically destructive urban systems as well as providing an opportunity to develop a holistic and sustainable alternative to current practices that generate waste and pollution. The treatise will focus on the management of polluted storm water, specifically along the Walmer catchment area which flows east into Airport Valley and Shark River Valley, and ways in which horticulture building systems can be utilised to achieve remedial action naturally, producing vast amounts of nutritious food for the surrounding community in the process. Impetus for this topic grew out of a concern that the author has for the current state of sustainable practices within South Africa, specifically regarding the relationship between water and agriculture (food). 60 – 70% of South Africa’s water demand is agricultural, with poor water management infrastructure and the current drought severely affecting the agricultural output (food supply) of the country. The increased demand puts immense pressure on South African farmers who have dwindling arable land and less water with which to cultivate crops. South Africa’s population is two thirds urbanised, meaning that most of the population lives in urban centres around the country. This treatise proposes that water-wise urban agricultural systems could be utilised to further cement food and water security in an urban setting by supplementing the food supply chain with local, city-grown produce. The research conducted will generate an architectural and urban intervention that marries the natural with the built environment in a strategically and intentionally designed relationship that exploits synergies between these two environments
