- Description: 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.

- Description: Although much research has been conducted on the greening of universities in the international context, not many studies focus on this topic in the South African context. A literature overview also identified that there are insufficient guidelines for green buildings at South African universities. Even though the Green Star rating tool is implemented in South Africa, no set of guidelines for green buildings exits at South African universities. The development of guidelines for green buildings at Nelson Mandela Metropolitan is a challenge which needs to be investigated. From the literature overview, it was possible to develop a framework containing seventeen green building aspects which could assist in developing green building guidelines. For this study, a two stage process was used to obtain information to evaluate green building guidelines critically at South African universities. Green building guidelines, as available at South African universities, were firstly explored by conducting a content analysis of all South African university websites. The information available on South African university websites regarding green buildings was scant and only two universities, namely the University of Cape Town and the University of Pretoria, reported that they had a green building. Stage two in the research process involved the empirical investigation of guidelines for green buildings at Nelson Mandela Metropolitan University. The results of the descriptive statistics showed that most building guidelines were perceived as important, but difficult to implement. The building guideline that was ranked the most important was the design of buildings that required low levels of maintenance or were maintenance free. The building guideline that was ranked the easiest to implement was to save energy in general. Considering the 17 suggested aspects and the five groups identified, a proposed set of green building guidelines was developed. The data gathered in this study is important as it could be utilised by the university to develop and implement the proposed green building guidelines.
