ENGLISH ABSTRACT: This study aimed to understand how Dukuduku Forest in Kwa-Zulu Natal has changed from 1960 to 2008 and whether the change in political regimes, during and post apartheid eras might have contributed to changes in forest extent. To achieve the aims, the following analyses were made: - Qualitative and quantitative spatial analyses of forest change; - Analyses of the correspondence of change with political changes in the country; - Assessment of perception of people living in the Dukuduku forest area. The Dukuduku land cover was mapped from aerial photos using ArcGIS 9.3 to determine whether or not there has been a significant change in the area from 1960-2008, in response to resource use pressures and to come up with the strategic sustainable management plan from the results found. Five aerial photographs were used to determine the changes in land cover from the year: 1960, 1970, 1992, 2005 and 2008. The Land cover types were classified into four classes, Indigenous Forests, Plantation Forests, Water Bodies and Other (open areas, cultivated land, and all the human disturbed and transformed land). The percentage of cover per class was compared across the years to determine overall change in land cover and the rate of change per year was also calculated. The results from the study showed that: - Natural Forest increased by 11% (700 ha), at the rate of 20.56 hectares per year between 1960 and 1992, which is the apartheid era. Between 1992 and 2008, the democratic era, the forest decreased by 34.4% (2472.31ha), at the rate of 168 hectares per year. - The Dukuduku forest community gains resources (timber and grass for construction, art, firewood, medicinal plants, grazing of livestock and food) from the forest. The people are willing to contribute in protecting the forest only if the governing authorities would include them in decisions made, as the NFA demands Participatory Forest Management, but which does not currently exist in Dukuduku.
AFRIKAANSE OPSOMMING: Hierdie studie ondersoek die verandering van die Dukuduku woud in Kwa-Zulu Natal vanaf 1960 tot 2008, en vernaamlik of die verandering in politieke regimes tydens en in die postapartheid eras tot verandering bygedra het in die woud se vorm. Om hierdie doelwitte te breik is die volgende analises gedoen: - Kwalitatiewe en kwantitatiewe ruimtelike analises van woudverandering; - Analises van die korrelasie tussen hierdie fisiese omgewingsverandering en politieke verandering in die land; - Analise van die persepsie van mense wat in die Dukuduku woudgebied woon. Die Dukuduku gronddekking is gekarteer met behulp van lugfotos, waarvoor ArcGIS 9.3 gebruik is om te bepaal of daar noemenswaardige verandering in die gebied plaasgevind het van 1960 tot 2008, in reaksie op hulpbrongebruike, en om ‘n volhoubare bestuursplan gestel voor wat op die bevindinge gebaseer is. Vyf lugfotos is gebruik om verandering in gronddekking te bepaal vir die jare: 1960, 1970, 1992, 2005 en 2008. Die Gronddekking tipes is geklassifiseer in vier klasse naamlik Inheemse Woude, Plantasiebosse, Waterliggame en Ander (oop gebiede, landerye en al die mens-versteurde en getransfomeerde gebiede). Die persentasie van elke dekkingsklas is oor die jare vergelyk om die verandering in algehele grond-dekking te bepaal, en die tempo van verandering is ook bepaal, asook die tempo van verandering. Die resultate van die studie wys dat: - Die natuurlike woud toegeneem het met 11% (700 ha), teen ‘n tempo van 20.56 hektaar per jaar tussen 1960 en 1992, tgedurende die apartheidsera. Tussen 1992 en 2008, die demokratiese era, het die woude verminder met 34.4% (2472.31 ha), teen ‘n tempo van 168 hektaar per jaar. - Die gemeenskap wat in die Dukuduku woud woon verkry hulpbronne van die woud (hout en gras vir konstruksie, kuns, brandhout, medisinale plante, weiding vir vee, en voedsel). Die mense is gewillig om by te dra tot beskerming van die woud indien die owerhede hulle sou betrek in besluite wat geneem word, veral omdat die nasionale Wet op Bosse voorsiening maak vir Deelnemende Bosbestuur, wat tans nie by Dukuduku gebeur nie.

The purpose of the study was to investigate the potential of Geographic Information Systems (GIS) in South African local planning. Planning is facing great challenges in contemporary South Africa and one of them is to consider new technologies to enable effective and efficient planning for the future. In meeting the overall aim of the study, a number of goals were set. The first goal was to provide an overview of GIS implementation in local governments from an international perspective. This goal was achieved by reviewing literature on the subject which encompassed the technology's evolution and factors affecting implementation. Practical examples were cited to demonstrate the application of GIS in planning. The second goal was to examine the role of GIS within the South African planning context. An investigation of the relevant legislation provided a context within which GIS could be implemented at the local level. In order to arrive at the second goal, a suitable planning process was derived from a review of applicable planning theory. The third goal was to illustrate practically how GIS could be implemented and integrated into the planning process at the local level. This goal was achieved by carrying out a project within the Pietermaritzburg suburb of Mountain Rise. The results of the case study showed that GIS has a potentially significant role to play in planning at the local level.

The Ferncliffe Catchment Conservancy has been identified, within the context of Pietermaritzburg, KwaZulu-Natal, for its important geographical and ecological features. The mapping and communication of these features to the broader community resident within the Conservancy have been envisaged as an important undertaking. A most effective way of achieving this goal was to use a Geographic Information System in the mapping exercise and in creating an inventory of the resources in the Conservancy and a monitoring database. Such spatial information would then provide stakeholders with a spatial context within which to appreciate the natural resources available and the problems associated with them. In undertaking this task, spatial data were acquired in digital form as well as from aerial photographs and 1:50000 topo-cadastral maps. These data were imported into ArcView GIS Version 3.1 where the mapping of the various resources was done. An inventory of the resources was created and a spatial database linking attributes that describe the physical environment, the natural vegetation, agricultural activities and the built environment, was set up. It became evident that using a Geographic Information System for natural resource management provides for integration of spatial information which would otherwise be contained in several separate databases and maps. Further, these data can be readily accessed, queried, upgraded and manipulated. For conservancies in urban and rural KwaZulu-Natal, and indeed, the rest of South Africa, to achieve their aims in natural resource management and monitoring, such an approach would be most efficient and effective.

The objective ofthe research project is to investigate the use of ArcView-GIS (a Geographical Information Systems software package) to promote cognitive development , at the University of KwaZulu-Natal. To understand the impact of ArcView-GIS as a learning tool will require an understanding ofhow it is used, what learning goals are held by educators and students and the type of assessments used to evaluate student achievement. It is argued that the use of GIS software promotes development of a wide range of skills. A research instrument to measure skills related to visualization, language, mathematics and logics was used to evaluate learners from a number of different groups which included science undergraduates, humanities undergraduates and GIS students (2 groups: one group took the test after the completion and the other group prior to the GIS course). In addition GIS experts and students evaluated the user interface of ArcVIewGIS. Results show that those learners exposed to GIS performed better in all the skills evaluated than any of the other groups. Also, experts and GIS students found the software interface satisfactory. The findings suggest that ArcView-GIS can support higher-order thinking by engaging students in authentic, complex tasks within an appropriate learning context.

Since the birth of a new democracy in the Republic of South Africa in 1994, municipalities across the country have embarked on several service-oriented programmes primarily to improve the quality of life of ordinary citizens within their areas of jurisdiction. Subsequently, these programmes which include Land Use Management System (LUMS), Integrated Development Planning (IDP), Integrated Sustainable Rural Development, Local Economic Development (LED), Urban Renewal Strategy, Property Rate Implementation and Municipal Infrastructure Grant (MIG) have been tailored to fast track service delivery in municipalities by building capacity and promoting small, medium and micro enterprises in local communities as a means of alleviating poverty (Local Government Programmes, 2004, paragraph 4). In order to speed up the development planning processes in the Province with regards to Integrated Development Planning, Spatial Development Framework and Land Use Management, Integrated Sustainable Rural Development, Local Economic Development (LED) and Municipal Infrastructure Grant (MIG), it has been identified that local authorities require a GIS application to integrate spatially related municipal information with other business information (Sarkar, 2004, paragraph 1). In view of this, the Department of Local Government and Traditional Affairs (DLGTA) has for the past six years, provided financial and technical support to the ten (10) District Municipalities and about thirty (30) Local Municipalities in KwaZulu-Natal to facilitate the establishment of Geographic Information Systems (GIS) in these municipalities (DLGTA Municipal GIS Capacity Building Manual, 2004). It is further noted that although a substantial amount of grant funding and technical support has been provided to the 10 District Municipalities and thirty Local Municipalities in KwaZulu-Natal, the full utilization of GIS as a decision-making support tool has not, as yet, been realised in some of these municipalities. This scenario thus calls for the need to ascertain municipalities' expectation and perception of the quality of GIS support services rendered to them by the Department and also to measure the gap thereof. To do so, the researcher employed SERVQUAL scale methodology to measure the service quality gap between municipalities' expectation and perception of the quality of GIS support services. A selfadministered questionnaire, which covers the five (5) dimensions of service quality, namely; tangible, reliability, responsiveness, assurance and empathy, was compiled and forwarded to the 10 District municipalities and 20 Local Municipalities in the Province to complete and return to the researcher within a specified time period. Fourteen (14) of the thirty (30) questionnaires sent out to these municipalities were returned to the researcher. The data was then analysed and conclusions were drawn. The research discovered that responsiveness, assurance, empathy and tangible dimensions are significant to municipalities in that they all had average expectation statement scores above 6 on the Likert 7-point scale. This means that respondents strongly agree to the expectation statements relating to these dimensions. On the other hand, the average expectation statement score relating to reliability dimension is below 6. The research result has shown that DLGTA is perceived by municipalities for rendering a desirable level of services to municipalities with respect to aspects relating to reliability, assurance, empathy and tangible dimensions. However, DLGTA seems not to provide prompt service to most of these municipalities and not showing signs of readiness to respond to their requests on GIS matters. It is also noted that there is a wide gap between municipalities' perception and expectation for responsiveness (-1.19), empathy (-0.90) and assurance (-0.98), and this seems to confirm the view that responsiveness and assurance dimensions are the most significant variables out of the five determinants of service quality, and thus require service improvement attention. The outcome of the survey reflects that the GIS concept is relatively new to some of these municipalities, and thus municipal officials want to feel safe in their transactions with DLGTA on GIS matters. As a result, they expect DLGTA officials to attend to them promptly and must have the knowledge to answer their GIS related questions. They strongly require DLGTA staff to give them individual attention and possibly have their best interest at heart. In this study, the responsiveness dimension is classified as having a poor service quality whiles the reliability dimension (with a narrow gap) has the superior service quality. To minimise or eliminate these gaps, it has been mentioned that DLGTA should be guided by the eight principles of Batho Pele which seem to take care of the key requirements of the five service quality dimensions as discussed in this dissertation. Based on this outcome, recommendations were made and a future research proposal outlined.

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.

With the increasing demands that human beings place on the environment, a concerted effort needs to be made to ensure that the environment is conserved and utilised in a sustainable manner. Therefore, it is imperative that all development actions be carefully scrutinised. The Integrated Environmental Management process may be just the process to address such development problems. The IEM process aims not only to identify those activities that would have excessively negative impacts on the environment it also looks at proposing alternative development strategies that may reduce the environmental impact of development. A tool which is being well received as being able to assist in such decision making is a Geographic Information System (GIS). The most suitable location for road networks that would have least environmental impact within the Eastern Shores State Forest, KwaZuluNatal, were determined by implementing the Analytical Hierarchy Process (AHP) along with Multi-Criteria Evaluation (MCE) process within real-time GIS. The location of road networks is a fundamental aspect of development due to the many negative impacts they may have on the environment. The AHP not only aided in identifying all the elements required to make a decision more accurately. It also allowed one to recognise the interrelationship between the various elements. The biggest advantage however, of using this model is that it allowed for the establishment of relative mathematically-based weights for the criteria. This effectively aided in identifying which of the vegetation types (ie. wetlands, swamp forest, grasslands, wetlands and coastal forest and thicket) in view of environmental consultants and ecologists would be most conducive to development. In so doing minimising the impact of the development. iii The MCE provided the ideal tool to incorporate these relative weights in order to combine them to arrive at an image that contained all the relative weights of all the various factors. A spatial database was constructed and a number of relevant images developed, using various GIS techniques. From these images it was possible to determine the most suitable locations for road networks within the Eastern Shores State Forest. Particular attention was focused on how GIS may be integrated within the IEM process. It was found that GIS could not only accurately determine where development should take place, but also established that it is an effective tool for aiding in the decision making process by providing accurate detailed maps of the area proposed for development. The success and overall simplicity of the procedure in this study suggests that GIS would be valuable to the IEM process.

This research focused on adventure tourism in KZN. The adventurer traveller is interested in remote pristine hotspots. A concern is that irresponsible behaviour on the adventurer’s part could lead to the destruction of the fragile natural environment, as well as negatively interfere with the local traditional cultural values. Adventure hotspots were identified by using the functionalities of a GIS. These findings were validated by tourism practitioners in KZN. The researcher also proposed a practical solution that could improve or enhance the behaviour of adventurers. Existing media were collated into information prompts. These information prompts were categorised in tables that could be linked to a mobile GIS environment. The researcher then examined the framework requirements for a mobile GIS. This resulted in a set of seven criteria that brought together the core essentials required for the conceptual framework of a mobile GIS device dedicated to the adventurer in KZN.

The problems posed by alien invasive plants to our environment and the need for clearing and control has been highlighted by the Working for Water (WFW) programme. Alien plant control requires careful planning, including budgeting. To date, costing and budgeting in alien plant control has largely been a combination of experience on the part of weed 'experts', coupled with much guess work. Weed controllers have through experience calculated the amount of time (or the work rate), recorded as labour days, required for different control actions of different weed habits. These work rates are for weed clearance under ideal conditions and do not take into account the effect of factors such as gradient, access and distance to the weed infestation. Factors affecting the work rate has been researched and modelled by researchers in both alien plant control and the timber industry. While the existing work rate model is useful in its present theoretical state, the model may be improved upon to make it more practical and applicable to the varying conditions of different areas. This research built on existing theoretical research on alien control work rates, and concentrated on two main areas: the adaption and incorporation of the existing research on work rates into a Geographical Information System (GIS), and the creation and demonstration of a Spatial Decision Support System (SDSS) for the management of alien plant control. The eMpofana river in the KwaZulu-Natal midlands was selected as the study area, as there was an existing alien plant control programme. Initially all factors, such as slope, access to weed infestations, terrain and penetrability of infestations, affecting the work rate in the research area were identified. An existing work rate model was then modified to account for the conditions of the research area. Regression analysis was used to derive the relationship between the various factors affecting work rate, creating a work rate model applicable to the study area. Using the results of the regression analysis together with work rate figures adapted from an existing alien plant control programme, a SDSS for alien plant control along the eMpofana River was created. The use of the work rate model and the SDSS in the development of weed control programmes was demonstrated by examining four different management approaches, each having a different management objective . The SDSS provides a spatial component to weed control planning and costing that has thus far not existed. What this research has achieved is the advancement of an alien control work rate model from a theoretical to a more realistic costing process. While some factors affecting work rate may not have been accounted for, the model does address the present inaccuracies in labour costing, and ultimately alien plant control costing. The research has highlighted the disadvantages of GIS in terms of affordability and expertise. The model has wider uses than the eMpofana River, and is the ground work for the further development of a user friendly model applicable throughout South Africa. More effective project budgeting will decrease the likelihood of project failure and this will directly benefit long-term weed control efforts.

Malaria incidence in the province of KwaZulu-Natal is influenced by seasonal climatic variations, drug and insecticide resistance, and population mobility within the region. Current control methods are directed at the malaria vector, the Anopheles arabiensis mosquito, through indoor residual spraying. Control of the dominant malaria parasite, Plasmodium falciparum, is done by treatmenting the symptomatic and asymptomatic parasite carriers with prophylactic medications of. A ceiling of effectiveness with current control efforts have been reached, necessitating the search for supplementary methods. The study area is located in the Ingwavuma District of northern of KwaZulu-Natal which adjoins the Mozambique border to the north, and includes the malaria areas of Ndumu and Makanisdrift. Homestead location coordinates were obtained with Global Positioning System (GPS) receivers and linked to malaria case records through homestead numbers which have been allocated to all homes in the area. The study includes the cases reported during 1993 and 1994 as this was the only data available when the project commenced in 1995. A geographic information system was used to undertake the spatial analysis to test the hypothesis that the malaria vector, Anopheles arabiensis, is localised to certain breeding sites during the winter months in northern KwaZulu-Natal. Identification of these winter 'seed point' breeding sites from which the onset of transmission spreads during the following malaria season, will allow them to be targeted for winter larval control measures. This will contribute to limiting the distribution and lowering the levels of malaria intensity in the region as a whole. The analysis also provided evidence of the maximum likely flight distance of the female mosquito given an adequate host supply in close proximity, thereby identifying those areas requiring additional prevention and control activities. Understanding the local epidemiology of the disease was necessary to determine which monthly malaria cases to include in order to identify the winter breeding sites, due to seasonal variations in the length of the mosquitoes life cycle. Medical geography, as a sub-discipline of geography, combines investigating spatial patterns with the epidemiological principles of medicine and zoology through scientific methods. It is traditionally divided into two approaches, the first being the geography of disease, under which this research falls, and the second being the geography of health care. The integration of the two disciplines allowed the results of the analysis to be presented in maps, graphs and tables in order to describe, interpret, test and explain possible associations between the location of the potential breeding sites and the homesteads at which the malaria cases were reported. The potential breeding sites consisted of the perennial pans, non-perennial pans and dams. Zones were created in the GIS at one kilometre intervals from these sites up to a distance of four kilometres, and the number of cases within each zone determined and corrected for the population at risk per 1000 people for comparative purposes. This spatial analysis was followed by the statistical analysis of the results to verify the findings. The results of the spatial and statistical analysis indicated that the perennial pans were used as the winter 'seed point' breeding sites, and that the maximum likely flight distance of the female mosquito, given an adequate host supply in close proximity, is 4 kilometres. The results will be made available to the local malaria research and control community who will assess the feasibility of implementing supplementary control measures.

According to the National Water Act No. 36 of 1998 (DWAF 1999), classification of the water resources in South Africa is the initial step towards the implementation of protection or management programmes. This study reviews different methods and systems of classifying river environments, in order to recommend a convenient, efficient and flexible classification scheme for describing the conditions of river environments. To meet this challenge, the study proposes the use of Geographical Information System (GIS) as a tool to link different controlling variables of river environments and thereafter analyse their spatial relationships. The study supports the use of GIS in river environment classification, with special emphasis on its functionalities that make it possible to explore and manipulate data interactively and easily. The GIS allows the user a flexible way to analyse the geomorphologic and ecological controlling variables of the river system. Thus , it enables different arrangements of these controlling variables for a number of classification purposes. The methodology used involves the GIS (database) analyses and map analyses to explore the relationships between geomorphologic and ecological controlling-variables of the river ecosystem. A case study of the KwaZulu-Natal Rivers demonstrates that valuable information for river environments could be derived from available geomorphologic and ecological datasets using methods of analyses within the GIS. In addition, the case study illustrates that it is possible to develop a working classification scheme for a particular purpose. The developed classification scheme can be improved by considering influential factors such as, the use of up-to-date datasets, consistent projection parameters and relevant scale.

The past centuries have been marked with massive land conversions from one land use category, usually natural vegetation, to another. The forces that drive these land use changes are complex and poorly understood. However, the study of land has been revolutionised by the introduction of spatial tools such as remote sensing and GIS that automate these complex issues and assist in the solutions of these geographic problems. Land use identification and classification techniques were used in conjunction with GIS to consistently and accurately extract and incorporate land use data from a series of remotely sensed images of Richards Bay Mineral's Zulti South Mineral lease. Eight land use types from Zulti South were identified and mapped from six different remotely sensed images taken at different time periods between the 21 st of September 1990 and the 1st of June 2001. This mapping technique was shown to have an accuracy of 87.6%. The data collated from this study enabled the monitoring and representation of the temporal and spatial differences in land use within a GIS. From the analysis carried in the GIS the land use dynamics within the lease could be quantified and modelled. The time series of the land use datasets indicated how much of the landscape is changing, what changes have occurred and where these changes are taking place. Accurate and timely mapping of land use provides vital information on the state of the mineral lease area and its environment, and facilitates the development of spatial trends from which predictions of land use and land use change can be made.

Rapid growth of cities is a global phenomenon exerting much pressure on land resources and causing associated environmental and social problems. Sustainability of land resources has become a central issue since the Earth Summit in Rio de Janeiro in 1992. A better understanding of the processes and patterns of land cover change will aid urban planners and decision makers in guiding more environmentally conscious development. The objective of this study was firstly, to determine the location and extent of land use and land cover changes in the uMhlathuze municipality, KwaZulu-Natal, South Africa between 1992 and 2002, and secondly, to predict the likely expansion of urban areas for the year 2012. The uMhlathuze municipality has experienced rapid urban growth since 1976 when the South African Ports and Railways Administration built a deep water harbour at Richards Bay, a town within the municipality. Three Landsat satellite images were obtained for the years, 1992, 1997 and 2002. These images were classified into six classes representing the dominant land covers in the area. A post classification change detection technique was used to determine the extent and location of the changes taking place during the study period. Following this, a GIS-based land cover change suitability model, GEOMOD2, was used to determine the likely distribution of urban land cover in the year 2012. The model was validated using the 2002 image. Sugarcane was found to expand by 129% between 1992 and 1997. Urban land covers increased by an average of 24%, while forestry and woodlands decreased by 29% between 1992 and 1997. Variation in rainfall on the study years and diversity in sugarcane growth states had an impact on the classification accuracy. Overall accuracy in the study was 74% and the techniques gave a good indication of the location and extent of changes taking place in the study site, and show much promise in becoming a useful tool for regional planners and policy makers.

The importance of managing and conserving cultural heritage can not be overemphasised. It is this realisation that has prompted the United Nations Educational, Scientific and Cultural Organisation (UNESCO) to declare identified sites of cultural importance as World Heritage Sites. The uKhahlamba-Drakensberg Park (UDP) was declared such a site in 2000, with its natural properties and cultural heritage as the criteria for inscription. The cultural heritage centres on the vast quantity of rock art that is renowned for its quality and diversity of subject. It is an important consideration for future generations to have the opportunity to view and understand this rich history and culture. There are increasing human and natural impacts on this non-renewable resource and to minimise these impacts and thus ensure the longevity of the resource it is necessary to develop a multi faceted selection of management and conservation tools. This realisation led the Programme of Geornatics, University of KwaZulu-Natal to conceptualise a project to develop a web-based Geographical Information System (GIS) specifically aimed at assisting in the management and conservation of rock art sites for the Valley of Pools in the Cathedral Peak Conservation Area of the UDP. Data for the project was captured in the field using Global Positioning System (GPS), digital camera and video camera as well as conventional hardcopy documentation. Existing digital spatial data and descriptive data were also collected from relevant stakeholders and a commercial organization. A pilot spatial database was then developed using ArcGIS@9 and Microsoft Access@, and later tested using a set of integrated simulated queries reflective of routine questions that users may request. Upon obtaining satisfactory responses to the queries, the integrated database was migrated and authored in ArcIMS®9 where it was further tested, and subsequently access was given to selected external professionals, both nationally and internationally, from various backgrounds, for evaluation purposes. Feedback from this process was favourably obtained.

This research aims at evaluating the level at which GIS is currently performing as a Decision Support Tool in Land Use Management Systems in KwaZulu Natal. Research was conducted amongst all ofthe district municipalities (in survey format, with a seventy percent response rate), as well as amongst representatives of three local municipalities, and representatives of the only Metropolitan municipality (all in the form of in-depth inten1iews). The results of the research were certainly revealing, and at points, significantly concerning. This research illustrates that despite the fact that the municipal LUMS should be in place, in most instances, the local municipalities have not completed their LUMS, and many districts have not finalised their specific components of the LUMS (namely the Land Use Framework, or LUF). Reasons for the difficulties experienced in developing the municipal LUMS were mainly capacity related, although there were a few additional impediments worth noting. Due to this, it was difficult to successfully evaluate the role that GIS is playing in LUMS as a Decision Support Tool. Despite this difficulty, it was still possible to evaluate the current use of GIS in the development of LUMS, as well as its perceived use in the future. Furthermore, the general perceptions regarding GIS as a Decision Support Tool were open for examination, along with how it will be used as such in LUMS This research confirms that GIS has been used to some extent in the development of the municipal LUMS, and that it will be used extensively in the future, particularly in Decision Support. This research concludes by offering various solutions or recommendations to the problems being experienced by the municipalities. These solutions originate both from points mentioned in the literature review, as well as from the responses to the questionnaires and interviews; and could assist in resolving the noteworthy problems revealed during the research.

In order to manage the often highly dynamic urban landscapes, it is important to map different themes from time to time. This study made use of Geographical Information System and aerial photographs to determine LULC transformation in the eastern suburbs of Pietermaritzburg in KwaZulu-Natal, South Africa. Land use land cover maps for the eastern suburbs (Copesville, Eastwood, Raisethorpe and Willowton) for the years 1989 to 2009 were generated and transformations based on twelve LULCs determined. Results in this study showed that the most significant increase were in residential (formal and informal) and industrial LULCs while the most significant decrease were recorded in the cultivated and open LULC. Generally, results in this study further show that urban LULC attributed to human influx has been at the expense of internal open green spaces and peripheral cultivated and uncultivated lands. The study concludes that aerial photographs in concert with GIS are valuable tools in mapping rapidly changing urban landscapes.

Rural farmers in the Nkwezela Area, with an average family size of 10 people, face a number of problems. The crops that are predominantly cultivated in the area, for subsistence (maize, dry beans, sorghum, potatoes, cabbages and turnips) have very low yields compared to the potential yield of the land. Natural resources in the area are increasingly deteriorating. In addition, arable land has shown remarkable signs of soil erosion that may lead to loss of soil fertility. This study evaluates the current land suitability for subsistence agriculture in Nkwezela based on climatic, soil, topographic and crop requirement data collected from different sources. The spatial parameters of the land resources were digitally encoded into a GIS database to create thematic layers of the land resources which was then compared to the crop requirement data of the selected crops grown in Nkwezela namely, maize, sorghum, dry beans, potatoes, cabbages and turnips. A GIS was used to overlay the thematic layers of the resources to select areas that satisfied the crop requirements of the selected crops. The results of the analysis of the land evaluation in the study area showed that the very hot summers, very cold winters together with the high clay content in the soils are the two limiting factors in Nkwezela. The land suitability maps indicate that sorghum is highly suitable in the area with dry beans and maize being relatively suitable. Cabbages are the least the least adapted crop with potatoes and turnips being not suitable due to the high temperatures during the growing season and the very cold winters. In conclusion Nkwezela is in a high rainfall area that is suitable for subsistence agriculture where warm season crops like dry beans, maize and sorghum are used for daily consumption by the community and can be cultivated in a sustainable manner. In addition the correct farming methods, procedures, liming and fertiliser requirements must be implemented, adhered to and maintained in order to improve crop yields in a sustainable manner and to encourage subsistence agriculture by the community.

Accelerated soil erosion is drawing a growing attention with the recognition that the rate of soil loss is too great to be met by soil formation rate. Weenen Game Reserve (WGR) is an area with an unfortunate history of prolonged soil erosion due to excessive overgrazing that led to severe land degradation with prominent visible scars. This problem triggered the general objective of estimating and mapping potential soil erosion in WGR. Assessing soil loss in the area objectively has important implications for the overall management plans as it is reserved for ecological recovery. The most important variables that affect soil erosion are considered as inputs in soil loss estimation models. In this study the RUSLE model, which uses rainfall, soil, topography, and cover management data, was employed. From the rainfall data, an erosivity factor was generated by using a regression equation developed by relating EI30 index and total monthly rainfall. The soil erodibility factor was calculated using the soil erodibility nomograph equation after generating the relevant data from laboratory analysis of soil samples gathered from the study area. Using exponential ordinary kriging, the point values of this factor were interpolated to fill in the non-sampled areas. The topographic effect, which is expressed as the combined impact of slope length and slope steepness, was extracted from the DEM of the study area using the flow accumulation method. For mapping of the land cover factor, in situ measurements of cover from selected sites were undertaken and assigned values from the USLE table before being related with MSAVI of Landsat 7 ETM+ image. These values were then multiplied to get the final annual soil loss map. The resulting potential soil loss values vary between 0 and 346 ton ha-1 year-l with an average of 5 ton ha-1 year-l. About 58% of the study area experiences less than 1 ton ha-1 year-1 indicating the influence of the highest values on the average value. High soil erosion rates are concentrated in the central part extending as far as the south and the north tips along the eastern escarpments and these areas are the ones with the steepest slopes. The results indicate a high variation of soil loss within the study area. Nevertheless, the majority of the area falling below the average might foresee that the soil erosion problem of the area can be minimized significantly depending largely on soil management. The most important areas for intervention are the medium and low erosion susceptible parts of WGR, which are mainly found in the flatter or gently sloping landscapes. The steepest areas are mostly covered with rocks and/or vegetation and hence less effort must be spent in managing them. Overall, the reported increasing density of the vegetation community in the area that reduces the exposure of soil from the impact of direct raindrops and surface-flowing water must be pursued further.

Fire is used in the management of ecosystems worldwide because it is a relatively inexpensive means of manipulating thousands of hectares of vegetation. Deciding how, where and when to apply fire depends primarily on the management objectives of the area concerned. The decision to ignite vegetation is generally subjective and depends on the experience of the fire manager. To facilitate this process, ancillary tools, forming a decision support system, need to be constructed. In this study a spatial model has been developed that is capable of simulating fire dynamics in savanna ecosystems. The fire growth model integrates spatial fuel and topographic data with temporal weather, wind settings and fuel moistures to produce a time-evolving fire front. Spatial information required to operate the model was obtained through remote sensing techniques, using Landsat Thematic Mapper (TM) satellite imagery, and existing Geographic Information Systems (GIS) coverage's. Implementation of the simulation model to hypothetical landscapes under various scenarios of fuel, weather and topography produced fire fronts that were found to be in good agreement with experience of observed fires. The model was applied actual fire events using information for prescribed burning operations conducted in Mkuze Game Reserve during 1997. Predicted fire fronts were found to accurately resemble the observed fire boundaries in all simulations.

This research applies the Near Repeat Calculator (NRC) to identify near repeat residential burglary patterns in the Hillcrest (KZN) policing area for the first time. A total of 490 residential burglaries, over a 12-month period, reported to Hillcrest police station were mapped (geocoded) and the near repeat calculations were visualised using the Geographic Information Systems (GIS). The month-to-month near repeat calculations are analysed and suggest that the NRC is a valuable tool that can predict the space-time locations of near repeat residential burglaries in the Hillcrest policing area.
Lolu cwaningo lusebenzisa i-Near Repeat Calculator (NRC) ukuhlonza amaphethini okuphindaphindeka kwezigameko zokugqekezwa kwamakhaya endaweni eyenganyelwe yisiteshi samaphoyisa sase-Hillcrest (KZN). Izigameko zokugqekezwa kwamakhaya ezingama-490 ezabikwa esiteshini samaphoyisa sase- Hillcrest esikhathini esiyizinyanga eziyi-12 zaboniswa emfanekisweni webalazwe lendawo (geocoded) futhi izilinganiso zamathuba okuthi ziphinde zenzeke izigameko zokugqekezwa kwamakhaya zaboniswa ngokuthi kusetshenziswe umfanekiso owenziwe nge-Geographic Information Systems (GIS).

Apartheid housing policies of the pre-1994 South African government, and the low-cost highdensity housing programmes of the post-1994 government, has given rise to numerous urban environmental problems, some of which could be addressed in a cost-effective and sustainable manner through urban greening, while simultaneously promoting biodiversity. Public participation in the planning of urban greening has been identified as being of vital importance, without which urban greening projects run a high, and expensive, risk of failure. Previous studies indicate that the greening priorities of residents in low-cost high-density housing settlements may differ considerably from those of managers and experts tasked with the protection and extension of the natural environment resource base. A system of participatory decision support is therefore required to reconcile the greening requirements of the community, and the ecological benefits of biodiversity. If language, literacy, map literacy and numeracy difficulties are to be avoided, and a sense of place or belonging is to be invoked, such a participatory decision support system should, ideally, be visually based, and capable of generating realistic eye-level depictions of the urban landscape. New computer-based landscape visualisation applications, which can directly utilise GIS, CAD and DEM data to produce detailed photo-realistic viewsheds, were deemed better suited to the task of visualising urban greening than existing GIS based mapping systems, CAD and traditional landscape visualisation methods. This dissertation examines the process of constructing a 3D computer model of the Mount Royal low-cost high-density housing settlement, situated in the eThekwini Municipality, KwaZulu-Natal, South Africa. Visualisations including terrain, natural features, indigenous vegetation, houses and roads were produced and submitted, with a questionnaire, to experts from different disciplines, Mount Royal residents and neighbors. Results from the expert survey indicate moderate support for visualisation in professional decision-making. However, both experts and residents expressed strong support for the accuracy and credibility ofthe visualisations, as well as for their potential in a participatory decision support system.
