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.

The Wattled Crane, Bugeranus carunculatus Gmelin, is presently classified as being 'Critically Endangered' within South Africa according to the Eskom Red Data book of Birds of South Africa, Lesotho and Swaziland, with a population of a meagre 235 individuals. Of this, 85% occur within KwaZulu-Natal and live predominantly on privately owned agricultural land. As a result thereof, Wattled Cranes and agriculture compete for the same resources. Up until now, the loss of viable habitat, as a result of agricultural development and afforestation, has been mooted as being the primary reason for the decline in numbers of the species. The advancements in the Geographical Information Systems field have enabled conservationists to acquire data, especially pertaining to habitat requirements, which were previously unattainable. This improved data acquisition is enabling for more informed decision making and better allocation of resources. The study therefore attempts to make use of a Geographical Information System to determine whether or not differences exist within the home ranges of active and historical Wattled Crane nesting sites, utilising the National Land cover database. The updated Land cover data for South Africa, although not completed at the time the present study took place, allowed for the interrogation of the various Land cover classes within an estimated home range. Natural Grassland was the predominant Land cover type within both active and historical home ranges, whilst both active and historical home ranges were subject to some degree of transformation. The potential impact of management practices in and around nesting sites warrants further investigation because this could not be determined through the analysis of land cover. / Thesis (M.Env.Dev.)-University of KwaZulu-Natal, Pietermaritzburg, 2006.
