One of the most controversial and dramatic features of recent city development is the phenomenon of access to land through informal means, which is a reflection of the lack of alternative delivery systems. Constraints on the supply of land for housing the urban poor have resulted in a large housing backlog, reSUlting in overcrowding, the emergence of unplanned housing such as backyard shacks and free standing informal settlements. In South Africa, the majority of the popUlation who have been historically constrained by racist and restrictive land allocation processes found it difficult to access well located and affordable serviced land. These constraints have resulted in poor people obtaining access to land through informal delivery systems. This effective exclusion of the urban poor from the formal land market has resulted in the emergence of the informal systems of land delivery, such as land invasions etc. Both internationally and in South Africa, informal settlements and squatting have represented a way of addressing and challenging market relations and state regUlation and thus, allow for poorer people to move into better located areas. The existing informal settlement within the Cato Manor area (Cato Crest) can be regarded as an example of this kind of urban process. The purpose of this dissertation is to assess the performance of the informal delivery systems in Cato Crest, to establish whether these systems have reached the urban poor and to look for ways of dealing with informal land mechanisms in the future. The findings from the survey indicated that in Cato Crest these illegal land supply systems have benefitted poor people in terms of job opportunities, proximity to the city and location. A number of recommendations can be made in this regard: that there is a need for a land policy on informal land supply systems, that which should seek to make strategically located land available for low income housing in the future. If this is not accomplished, illegal land occupation will continue unabated until no land will be available for low income housing. / Thesis (M.Sc.U.R.P.)-University of Natal, Durban, 1995.

The spatial and temporal variations in water quality of selected rivers in the Durban Metropolitan Area were investigated using a Geographical Information System. Dissolved oxygen (DO), turbidity, pH, phosphorus and Escherichia coli (E.coli) were selected as water quality parameters for the study. The study reflects a pattern of water quality deterioration due to the numerous land use practices that have had an adverse impact on the receiving waters. In addition, the communities that use this water for various purposes have been impacted on. Spatially, an impoverishment of water quality conditions were observed by the increase of phosphorus, turbidity, DO and E.coli. The parameter of E.coli represented the worst water quality status in all the catchments of the study area. These were attributable to land use factors such as informal settlements and urban formal settlements. For the parameter of pH, no adverse water quality was present. Temporal evaluation of the data indicated that although there were no distinct trends that could be directly related to rainfall, some of the parameters showed some influence by rainfall, through runoff. Selected rivers of the Durban Metropolitan Area reflect poor water quality. There is an urgent need for the implementation of a strategy for improvement. The evaluation of water quality forms the basis for integrated catchment management (ICM), which has been advocated as the only holistic way to manage water resources. Due cognisance must be taken of the various land use practices, which have a great impact on water quality. There should be concerted efforts to reduce the input of pollutants that may have adverse effects on water quality, e.g., by provisions of sanitation facilities in informal settlements. It is hence recommended that for any improvement of water quality to occur, there needs to be an implementation of ICM for all the catchments. / Thesis (M.Sc.)-University of Natal, Pietermaritzburg, 2002.

This research study addresses the issues associated with lost and wasted urban spaces. Lost and wasted spaces refer to areas which have no human activity or proper human interaction. They are the leftover unstructured landscape at the base of buildings. They also include abandoned buildings, waterfronts, train yards, vacated military sites, and industrial complexes. The research outlines the causes of lost and wasted urban spaces which occur within the eThekwini Municipality and urbanised spaces in general. Through the use of case studies and precedent studies, the research study investigates the various techniques, technological advances and approaches that could alleviate wasted spaces in the city. The Durban Esplanade and Point Waterfront development constitute the main case study areas; however, to fully understand how and why lost and wasted spaces occur within the urban environment, various other spaces which make up the cityscape were also investigated. For example, the city transport infrastructure and green spaces do not form part of the case studies, but have been included as part of the research into lost and wasted spaces. The research study seeks to take the issue of lost and wasted urban spaces a step further by combining it with issues related to sustainability. Through the use of the case studies, various possible solutions and alternatives to the alleviation of lost and wasted urban spaces are outlined and investigated. Examples of how lost and wasted urban spaces could be transformed from problem areas to spaces of opportunity are also explored. This was achieved by making use of computer-aided design and graphic illustrations to indicate the possible solutions that could form part of a holistic approach to the issues surrounding lost and wasted spaces in the built environment. The current planning legislation is outlined in order to provide a thorough understanding of the interconnection between environmental and sustainability issues which relate directly to the cause of lost and wasted spaces. Furthermore, the research study highlights the involvement of various built environment disciplines, including planners, architects and urban designers and investigates their role in the alleviation of lost and wasted urban space. / M.T.R.P.
