A sample was drawn from the students and lecturers at three selected tertiary institutions. The secondary objective was to determine who is deemed competent to teach jazz at tertiary institutions: professional players, professional players with a teacher-training qualification in jazz, or both. Three of the tertiary institutions in South Africa that offer jazz as part of their curricula were chosen: the University of Cape Town, the University of Natal, Durban, and the Technikon Natal. A questionnaire survey and interviews were utilised as the means of collecting information about issues concerning jazz education. A quantitative research design was used to analyse the results obtained from the questionnaires. The results were tabulated in basic descriptive statistical form and the interviews were qualitatively analysed. In addition, five hypotheses were formulated and tested using chi-square tests. A number of the interviewees supported the idea of equipping professional jazz teachers with general music educational principles; however, there were those who felt that their experience in the field was sufficient to enable them to be competent jazz teachers. The results from both the student questionnaire and lecturer interviews indicated that a combination of both professional players and professional players with a teacher- training qualification are needed. It was recommended that further research on jazz education should be undertaken to account for issues relating to teacher training in music education in South Africa. A curriculum that suits students and professional players who are interested in becoming competent jazz educators should be developed.

Bibliography: leaves 140-151. / The Swartland and Sandveld are situated in the Western Cape province (political limits) in what is also known as the southwestern Cape region . This area falls within the winter rainfall (or Mediterranean) region of South Africa and has a sharply defined seasonal climate. Vegetation in the region is unique. The soils in the Swartland and Sandveld vary greatly over short distances, making this area vulnerable to varying erosion rates. Land use in the Swartland and Sandveld is mainly agricultural. Soil erosion is driven by the force of wind and or water. Sheet flow is what is considered as unconstrained water erosion together with rainsplash, while piping, rill and gully erosion are all forms of constrained water erosion. Erosivity and erodibility are both important factors in determining the vulnerability of an area to soil erosion. By their understanding of the factors involved in the course of degradation, researchers can determine the most effective conservation policies for a region. Of course, the influence of humans on the land should never be under-estimated and should be seen as a potent determinant of the erosion potential. The use of remote sensing and G.I.S. are essential in the development of erosion maps, and to assess possible changes that over time in the erosional situation in a region. As an analytical and data storage tool, these techniques are very useful, even essential. The total decrease in gully erosion from 1938 to 1989 in the Swartland amounts to 85% compared to the gully erosion in 1938. In the Sandveld wind erosion decreased with 17% from 1928 to 1986. Soil conservation in South Africa has come a long since the 1930's and much of the experience and the lessons gained in the last six of seven decades have been incorporated in the countries new conservation Act. It has been concluded that the slowing down of the denudation process in the region, coinciding with effective new conservation strategies, are the principal reasons for the results obtained in this research project. It must be noted however that without the intervention of the conservation efforts in the Swartland and Sandveld, the remarkable improvement in the water erosion situation (85%) would not have been obtained. The overall improvement (17%) in the Sandveld lags that in the Swartland and even shows a slight deterioration of the wind erosion situation found in 1974. There are therefore grounds for caution, since wind erosion is still very much relevant and not fully contained in the Sandveld. Further research into this situation would indeed be beneficial.

Bibliography: p. 54-57. / This report is concerned with the environmental impact assessment of two alternative access roads, the Western Access Route (WAR) and the Least Cost Alternative Route (LCAR), to the proposed Mohale Dam site, Lesotho. The procedure adopted by the Environmental Evaluation Unit (EEU) study team for the assessment of environmental impacts associated with the development of the two routes, is critically reviewed. A comparative evaluation of the alternative routes is undertaken. The preferred access route, which best satisfies the above environmental criteria, is recommended . In January 1993, the Environmental Evaluation Unit (EEU) of the University of Cape Town was appointed by Gibb-Bergman Joint Venture (GBJV), to assess the environmental impacts associated with the development of an access road from the Lesotho-South Africa border to the construction site of the proposed Mohale Dam (Phase lB), Lesotho Highlands Water Project (LHWP), Lesotho. An existing road, termed the Western Access Route (WAR), was identified as a possible access route. This route would require upgrading to a suitable standard for the passage of heavy construction vehicles, and, in addition, the construction of a bypass of the central business district of Maseru . At an early stage of the study, an alternative access route to the WAR was identified from eight possible alternative routes. This route has been termed the Least Cost Alternative Route (LCAR). The EEU study team undertook a full assessment of the environmental impacts associated with upgrading the Mountain Road/Western Access Route (WAR) and the construction of the LCAR. These detailed impact assessments are documented in Report EEU/2/93/104a, EEU/2/93/104b and EEU/2/93/104c, submitted with this report.

Hyrax middens from the De Rif site in theCederberg Mountains of the south-western Cape have been collected and sampled. Through the application of pollen analysis to the midden material, local plant communities were inferred and a palaeoenvironmental reconstruction of prevailing conditions over the period of accumulation was produced. An assessment of the overall pollen assemblages indicates that typical mountain fynbos were present at De Rif throughout the last 28 ka and that generally there were no major changes in vegetation communities throughout this period.

The proposed GTFCA encompasses an area of 2,774 km2 (277,400 hectares) straddling either side of the Orange River, which represents the international border between South Africa and Namibia. The author of this dissertation was a member of a small team of postgraduate students from the Department of Environmental and Geographical Science at the University of Cape Town who spent six months, from November 1997 to May 1998, focusing on the South African section of the proposed GTFCA, which covers approximately 2,000km2 and is situated in the Northern Cape (MAP 1).

Bibliography: p. 124-141. / The Outeniqua and Langkloof Mountains are Islands of fairly pristine mountain fynbos surrounded by intensively cultivated agricultural land, in the Southern Cape. Active management is imperative if the ecosystems are to remain viable. An adaptive system of management is used to determine a management policy for the area. Literature and field surveys supplied data for a basic description of the ecosystems Management objectives were formulated to realize the following Land-use types: water conservation, nature conservation, agricultural utilization timber production, recreation and research. A Mountain Catchment Area is proposed to realize water conservation aims on private catchment land. An efficient classification system is essential for planning. The study area was subdivided, according to land-use and management objectives, into various management zones: water conservation, restricted management, fire control and nature conservation zones. The basic subdivision of zones are compartments.

The hypothesis for this dissertation was that EIA follow-up helped to bridge the divide between prediction and reality and is effective in ensuring an adaptive EIA process towards sustainable development. This hypothesis was explored through the investigation of six research questions in four case studies. The research questions were formulated from a conceptual framework derived from various literature sources on EIA follow-up research. These questions cover a range of issues that inform effective EIA follow-up, from theory to best practice. In the four case studies evaluated, the predicted impacts and Environmental Management Plan (EMP) mitigation measures correlated to a high degree with actual impacts. The correlation between predicted- and actual impacts did not always mean that the goal of EIA was achieved. In complex, natural systems predicting impacts cannot be completely accurate and effective. It is important to rather invest in an adaptable management system to cope with the reality of not understanding the complexity of impacts on the environment. The focus in deciding when EIA is required should therefore be the sensitivity of the receiving environment rather than predetermined triggers and thresholds. It was found that it is important to establish the baseline condition of the affected environment.

BIbliography: pages 73-75. / This summary contains three sections. Firstly a review of the Baseline Information Report followed by a presentation of the findings of this assessment report. The findings are the impacts of closure. Finally mitigatory measures are recommended. The Baseline Information Report, 5/92/87, was produced by the Environmental Evaluation Unit (EEU) with the assistance of the 1 992 Masters students of the department of Environmental and Geographical Science. Its primary aims were to introduce the NM 2005 study, describe methods used and present results. A brief description of its contents follows : De Beers Namaqualand Mines (DBNM) commissioned the EEU to undertake a study, seeped to assessment ofthe socio-economic effects of mine closure and recommendations for mitigation. The effects or impacts; vary in their magnitude and significance further more they effect a wide range of people and organisations. To establish the magnitudes and significance of the socio-economic effects, the environments of Namaqualand and the Transkei region, in which the impacts are to occur, needed definition. The defined environments acted as a baseline for changes brought about through DBNM closure. Firstly, the history of the Namaqualand people and their socio-economic activity trends was established and issues were put in context. History indicates Namaqualand went through a land-grabbing phase, during which the Khoi Khoi people were dispossessed of their land to make way for trekboer farming and copper and diamond mining (Fig, 1991). The latter industries continue to dominate the region today, providing labour opportunities for Namaqualand's coloured majority and 58 %of the region's gross geographic product in 1991. The agricultural and fishing industries are marginal and are expected to remain that way (Dunne, 1988). Secondly, the Transkeian environment, its history and trends were established using the Herschel District as microcosm for study. The results indicated a history of forced removals. The present subsistence community are struggling with poor infrastructure and are heavily dependant on pensions and money sent home from migrant labourers. Having established some background the report continues by describing the social effects which could be felt by the DBNM employees, their dependants, their communities and other interested and affected parties. The social effects were gauged through surveys, meetings, written and telephonic correspondence. The employees were divided into three groups; Namaqualand, Transkei and mine town, based on the regions the employees called "home". The survey results showed that the three groups were distinctly different. Indicating that group members along with their dependants and communities, could be effected by DBNM closure to different levels of significance. Their concerns with closure, revolved primarily around; unemployment and the lack of opportunities, education, quality of life and the regional economy. The groups also suggested mitigation such as the establishment of a development aid fund, returning DBNM land to the Rural Coloured Areas and DBNM involvement in local projects. The economic effects will be felt by businesses who deal with DBNM and its employees. The businesses in the Namaqualand region are likely to experience the most significant effects. While the national and international communities are likely to be influenced to a lesser extent. Economic effects were established through the examination of macro-fiscal flows, input-output analysis and a business survey in Namaqualand. The macro scale study was covered by the input-output analysis which found South Africa, outside of development region A, is likely to experience the largest financial loss, greater than that of the local region and the international community. In particular, the services and machines sectors were predicted to experience the greatest loss due to closure. On a micro scale, the survey of Namaqualand businesses indicates that 17 % of the regions turnover emanates from dealings with DBNM and its employees. DBNM closure would result in business closures (3 % in Springbok and 5 % elsewhere in Namaqualand) and retrenchments (a predicated 250 or 4. 7 % of business employees) primarily in Springbok, Steinkopf and Komaggas.

Includes bibliographical references. / With the continued spread of invasive alien vegetation in South Africa, there is a growing need and recognition in protecting ecosystem service delivery. While most literature on ecosystem services has focussed on provisioning and supporting services, this study looks at the less addressed cultural ecosystem services, specifically focussing on tourism and recreation. This research explores the relationship between tourism and invasive alien vegetation. This was carried out at firstly a national level, utilising primarily quantitative methods to identify, and map alien vegetation overlaps with key tourist sites in South Africa. This was followed by a more in-depth qualitative analysis, at a case study level, focussed on the Stellenbosch municipality, to determine the understanding and perceptions, tourists, landowners, and tourism operators have regarding invasive alien plants. Moderate to high levels of infestation were found overlapping various key tourism destinations across the country. The most heavily impacted provinces include the Western Cape, Eastern Cape, and KwaZulu-Natal. In certain areas, invasion levels at key tourist destinations raise concerns regarding the management of these sites. The findings of this research signify a close link and definite relationship between tourism, and invasive alien vegetation. Looking specifically at tourism as a cultural ecosystem service, and the relationship this service has with invasive alien vegetation, future studies need to recognise the significance of this association, while the broader tourism industry needs to recognise the potential threats invasive alien vegetation poses to their operations. Furthermore, this research identifies the value in combining qualitative, human dimensions, with quantitative data and mapping approaches in ecosystem services research.
