The research focuses on the contemporary pollen rain-vegetation relationship for vegetation communities within the Natal Drakensberg, a region which is recognized as having the potential for extensive palynological investigations. The objective was to investigate the fundamental assumption underlying palynology, viz: that the pollen rain of a particular region is indicative or representative of the existing vegetation of that region. If the modern pollen rain is indicative of and/or distinctive for a particular vegetation community then the principle of methodological uniformitarianism can be applied, which states that the present day patterns and relationships can provide a factual basis for the reconstruction of the past through the extrapolation of modern analogues backwards in time. A vegetation survey was conducted in thirteen communities identified as pertinent to the research and a two-year modern pollen rain sampling programme was carried out, using both surface soil and pollen trap samples as a means of recording and quantifying the pollen rain. Once the necessary sample preparation and pollen counts had been performed, descriptive and numerical/statistical methods were employed to determine and describe the existing pollen-vegetation relationship. Descriptive analysis of the data sets was carried out with the aid of spectra depicted as rotated bar graphs and representing the relative percentage frequencies of the collected/counted taxa. Annual and seasonal pollen influx values were calculated and presented. Analysis of variance was applied to test various hypotheses related to sampling strategy and pollen influx variation. Statistical methods employed were two-way indicator species analysis (a classification analysis technique), detrended correspondence analysis and principal components analysis (ordination techniques), canonical correlation analysis (for data set association) and multiple discriminant analysis (for determination of vegetation zonal indices). The latter technique allowed for the probability of modern analogues to be assessed which are necessary for accurate interpretation of fossil pollen assemblages if the assumption under investigation is correct. The findings of the study were that the modern pollen rain-vegetation assumption holds true. Recommendations are put forward regarding future contemporary pollen studies with regards to the number of soil and pollen trap samples required, the magnitude of the pollen count and the numerical/statistical techniques most appropriate to clearly interpret the results. The conclusions are that future fossil pollen spectra can be expected to provide a good indication of former regional vegetation patterns for the study region. The study has extended the limited understanding of the contemporary pollen rain-vegetation relationship in South Africa and enables the interpretation of fossil pollen spectra to be carried out with greater confidence. This in turn lends greater credibility to possible Quaternary environmental change models required to help understand present and possible future environmental change.

Thesis (MPhil)--University of Stellenbosch, 2005. / ENGLISH ABSTRACT: This paper reviews the status of world aquaculture with a primary focus on Sub-Saharan and Chinese freshwater aquaculture, and proposes a commercial integrated farming model for implementation in rural areas in KwaZulu-Natal. The model combines the paradigms of age-old Chinese integrated pond farming principles with a commercial approach in the socio-economic context of Sub-Saharan Africa. The project's objective is to contribute to the alleviation of poverty through economic development in rural areas using environmentally and economically sustainable farming practices. The project's medium-term goal is to achieve the critical production volume to warrant vertical integration into a hatchery, feed mill and processing facility. Integration would reduce operating costs and afford better standards of basic services. The project's long-term goal is to grow and expand the model to make a contribution to global food security through distributing a fish-based, nutritionally balanced meal to famine relieve efforts in low-income food deficiency countries (LIFDC). The model proposes the development of individual farms each with a production capacity of 40 to 60 tons of fish per annum. The species available include tilapia, catfish, carp, mullet, bass and eels. The farms will each consist of eight grow-out fishponds totalling 4 hectares of water surface area, a basic homestead and 6 hectares for crops and livestock rearing. The farms are designed to utilize the nutrient rich effluent from the fishponds to flood-irrigate crops planted in the fields below. Through application of the principles of the integrated approach to fish-crops-livestock farming as applied by the Chinese over the last 2,000 years, the farms are designed in a way that nothing is wasted. The waste product from one system becomes input for the next system. The integrated approach is extremely cost effective and lends itself to total organic farming adhering to environmentally responsible and sustainable farming principles. Two hundred such farming units would produce a total of 8,000 to 12,000 ton per year that equates to double the current combined freshwater aquaculture production from all the SADC member countries. / AFRIKAANSE OPSOMMING: Die werkstuk bied 'n oorsig van akwakultuur in die wêreld, met 'n primêre fokus op die stand van varswater akwakultuur in Sub-Sahara en China. 'n Ontwikkelingsmodel vir geïntegreerde kommersiële boerdery word voorgestel, in die plattelandse dele van KwaZulu-Natal word woorhou. Die model koppel die konsepte van eeue-oue Chinese beginsels van geïntegreerde visboerdery met kommersiële winsgewendheid, binne die sosio-ekonomiese konsep van sub- Sahara Afrika. Die doel van die model is om 'n beduidende rol te speel in die verligting van armoede deur die ontwikkeling van ekonomiese aktiwiteit in plattelandse gebiede d.m.v. omgewings- en ekonomies volhoubare boerderypraktyke. Die projek se mediumtermyndoelwit is om die kritiese produksievolume te bereik wat vertikale integrasie met 'n visbroeiery, 'n voermeule en 'n prosesseringsfasiliteit sal regverdig. Dit saloperasionele kostes verminder en beter beheer verseker oor hierdie basiese insette. Die langtermyndoelwit is om die model uit te brei ten einde 'n bydrae te maak tot globale voedselvoorsiening deur die verspreiding van 'n voedsame, gebalanseerde maaltyd met vis as basis, as hongersnoodverligting in lae inkomste lande met 'n voedseltekort. Die model stel 'n reeks individuele plase voor, elk met 'n produksiekapasiteit van 40 tot 60 ton vis per jaar. Die beskikbare spesies sluit in tilapia, baber, harder, swartbaars en paling. Elke plaas sal bestaan uit agt uitgroeidamme van 'n halwe hektaar elk, 'n totaal van vier hektaar wateroppervlakte, 'n woonhuis en ses hektaar vir gewasse en veë. Die plase is ontwerp ten eide die voedingsryke uitvloeisel van die visdamme te gebruik vir besproeiing van die laerliggende landerye. Deur gebruik te maak van die beginsel van integrasie van 'n vis-, gewas- en vee-boerdery, aan die hand van die Chinese ontwikkelingsmodel oor die afgelope 2,000 jaar, word gepoog om niks te vermors nie. Die afvalproduk van een stelsel word 'n inset in die volgende. Hierdie benadering is uiters koste-effektief en leen homself tot organiese boerdery praktyke wat voldoen aan bewaringsbewuste en volhoubare boerderymetodes. Tweehonderd plaaseenhede sal 'n gesamentlike bydrae van 8,000 tot 12,000 ton per jaar lewer, wat gelykstaande is aan dubbeld die huidige gekombineerde varswater akwakultuurproduksie van al die SADC-Iedelande.

The South African government has introduced mechanisms and plans to alleviate poverty and to monitor and evaluate the impact of the policies and programmes to the reduction of poverty. In its quest to eradicate and alleviate poverty, the government has prioritized poverty alleviation in its development agenda. In efforts to fight poverty, the government has since 1994, implemented various programmes that are aimed at alleviating poverty through stimulating employment, developing skills and improving service delivery. The poverty alleviation programme is one of the strategies that was implemented by the government, as a means to eradicate poverty. At the community level, depending on the nature of the programme, efforts have been made to incorporate mechanisms which enable poor people to play an active role in deciding how the benefits from programmes are distributed. The study was based on the projects identified by the community of Amajuba district in Dannhauser area in KwaZulu Natal. The Dannhauser Municipality in partnership with the Department of Agriculture and Environmental affairs have played a vital role in this regard by supporting the establishment of the Thuthukani project in 2004. In an attempt to assess the impact of the poverty alleviation projects, this study investigated the role played by the Thuthukani project in local economic development of the Dannhauser community in the Dannhauser Municipality. Participants included the Thuthukani project members, and the extension officer from the Department of Agriculture and Environmental affairs. The study found that, indeed poverty alleviation projects play a role in local economic development since they contribute towards job creation and improvement of the socio-economic status of the local community.

The Ngoye Granite Gneiss Formation is located in the Natal sector of the Proterozoic Namaqua-Natal Mobile Belt, about 10 km southwest of Empangeni. It forms a prominent east-west trending elongate whalebacked massif some 30 km in length, within amphibolitic gneisses and schists of the Tugela Group. A suite of twelve different, gneissic granitoids has been-recognised within the Ngoye Formation on the basis of field relationships, mineralogy and supportive geochemistry. They range in composition from peraluminous syenite to peralkaline granite. Peraluminous varieties are typically muscovite and garnet-bearing whereas metaluminous granites in the formation contain olivegreen biotite and/or hornblende and sphene. Riebeckite, aegerine and yellow-brown biotite, with accessory fluorite and zircon are characteristic of the peralkaline granites. Geochemically, the samples analysed display a range in SiO₂ from 63,79 - 78,47∞, are extremely depleted in CaO and MgO, while being enriched in Na₂O and K₂O. Depletion of CaO relative to alkalis is shown by an alkali-lime index of only 36, suggestive of an alkalic character. The agpaitic index (A. I. = mole Na₂O + K₂O/AL₂O₃) of the peralkaline samples ranges between 1,02 and 1,16; which classifies them as granites of comenditic affinity. Various chemical classification schemes have been tested and evaluated, of which the RI - R2 multicationic diagram provides results most similar to modally-derived terminology. Accordingly, the Ngoye granitoids are shown to range from minor syenites and alkali granites to predominant monzo - and syeno-granites. Trace element data indicate that the peralkaline granites are enriched in Nb, Zr and Zn relative to the other, non-peralkaline, granites in the formation. In addition, radioactive, magnetite-bearing quartz-rich rocks associated with the peralkaline granites, have extremely enhanced contents of Nb, Zr, Y, Zn, U, Th and to a lesser extent Sn and W. Peraluminous and near-peraluminous granites have the highst Rb/Sr and Rb/Ba ratios of all samples analysed, as well as enhanced Sn, U and Th contents while Zr is notably depleted. Small, muscovite-rich pods associated with muscovite-bearing granites are highly enriched in Sn. The application of certain discriminants based on modal and geochemical parameters has shown the Ngoye Formation to comprise typical "A" - type granites. "A" - type granites are characteristically intruded as ring complexes into anorogenic or post-orogenic tectonic settings in attenuated or epiorogenically-domed continental crust. Comparison of the Ngoye Formation wi th the well-known "younger granite" complexes of Nigeria and Saudi Arabia reveals marked similarities. The inference is therefore that the Ngoye Formation represents a metamorphosed "postorogenic" granite complex with most of the hallmarks of "A" type or "within-plate" magmatism. Four phases of deformation (D₁ to D₄) are recognised within the area mapped. Evidence of D₁ deformation is rare, but rootless folds within the transposed layering in the amphibolitic country rocks reflect the intensity of this prograde metamorphic event, M₁, during which upper amphibolite grades were achieved. Field evidence shows that the Ngoye granites were intruded after the D₁ event and prior to D₂. This latter event caused widespread folding about east-west F₂ axes, with the development of a pervasive S₂ planar fabric within the antiformally folded Ngoye Formation. S₂ is locally developed in the amphibolitic country rocks. The D₂ event culminated in the development of northward-directed overthrusting and retrogressive ,M₂, metamorphism of mylonitic thrust planes. Lateral shearing characterizes D₃, with development of macroscopic mylonites and mesoscopic conjugate shear zones. This was in response to a sinistral sense of movement, as indicated by prominent sub-horizontal extension lineations (L₃) and microscopic asymmetric augen structures. D₄ is deduced from stereograms and is indicated as cross-folding of F₃ fold axes. / Thesis (M.Sc.)-University of Durban-Westville, 1985.

Submitted in fulfillment of the requirements for the degree of Masters of Technology: Tourism and Hospitality, Durban University of Technology, Durban, South Africa, 2017. / The past decades indicate enormous interest in tourism as a tool for regional economic development. However, it is not always clear if tourism creates a significant contribution to local destination communities, as, in most cases, benefits from tourism emerge slowly and usually accrue to certain groups within the community. This study is driven by the researcher’s desire in determining tourism’s contribution to local community development, and to seek ways in which the local indigenous community can enhance their standard of living through tourism. Hence, increased understanding of tourism’s contribution to community development is necessary to establish strategies to ensure that employees and community receive equal benefits from tourism. Therefore, the study sought to investigate ‘the contribution of tourism to local community development, using Shakaland Zulu Cultural Village (SZCV) as a case. A qualitative and quantitative approach was employed. However, more emphasis was placed on the qualitative approach. The study sample compromised of 84 purposely selected employees of SZCV. The data collected were coded and organised according to the interview questions and were analysed and interpreted according to five analytic categories that were based on the objectives of the study. The findings of the study indicated that: SZCV contributes to local community development; and SZCV has different tourism employment categories that improve the community’s livelihoods in Eshowe, including cultural dancers, cultural chief, traditional herbalist, sangoma, arts and craft workers, chefs, receptionist, reservationist, spaza shop retailer, food and beverage manager, front office manager, maintenance manager as well as cultural manager. The study further revealed that a few respondents received training for their positions; and that the majority of employees are involved in the decision-making process within the SZCV; however, this involvement was not at a strategic level. Furthermore, the study recomended that local community development in Eshowe needs to be improved especially through the diversification of the cultural village. This is attainable by forming a partnership with other tourism business in close proximity to the SZCV that attract a high volume of tourist, to increase the possible benefits to communities that are residing along SZCV. / M

Largespot pompano, Trachinotus botla, is a surf zone carangid with a cosmopolitan distribution in subtropical and tropical waters. Within South Africa, the species occurs along the KwaZulu-Natal coastline where it is a popular recreational fishing target. Recreational fishing in southern Africa has developed significantly in recent years, and is now regarded as an industry with huge economic potential. The long-term contribution of South African recreational fisheries to local economies is reliant upon sustainable exploitation through effective management. Trachinotus botla was found to grow rapidly with maximum observed age of six years. Otolith growth zone deposition was validated using edge analysis. Growth was similar between males and females until ~350 mm FL after which females continued to grow while growth in males slowed. The resulting overall sex ratio was slightly female-biased (1 male: 1.3 females). Trachinotus botla matures early with all fish considered to be mature at 290 mm FL, which corresponds to an age of three years. A protracted spawning season was observed ranging from November to February and there was evidence to suggest that T. botla is a serial spawner. Dietary analysis indicates that T. botla is an opportunistic predator with a catholic diet. The opportunistic utilization of “superabundant” prey items is a fundamental characteristic of the species feeding habits. An ontogenetic dietary shift was observed at approximately 300 mm FL that was linked to a shift in habitat preference. This thesis provided the first evidence that infection by the tongue-replacing isopod, Cymothoa borbonica, reduces the growth rate of wild host fish populations despite not affecting the diet, feeding habits and feeding frequency of their hosts. These results also highlighted the inadequacy of condition factor as a proxy for quantifying the effects of cymothoids on their hosts, and identified the need to incorporate host age when assessing the effects of parasite infection. Information on the life-cycle of C. borbonica, including estimates of the hypothesized “infectious” period and its longevity were obtained through analysis of parasite infection patterns as a function of host age and length. An assessment of the T. botla shore fishery of KwaZulu-Natal using historical catch data revealed that the fishery is stable. Productivity of the T. botla fishery increased towards the north of KwaZulu-Natal. Distinct seasonal variations in the T. botla fishery were also noted with catches peaking in summer months and lowest during winter. A per-recruit assessment revealed that the species is currently underexploited (SBR = 62% of pristine levels), and fishing mortality rate could be doubled before reaching the spawner biomass-per recruit target reference point of FSB₄₀. A combination of the life history characteristics of species, the nature of the recreational shore fishery together with the current management regulation of 5 fish person⁻¹ day⁻¹ has ensured the sustainable utilization of the T. botla resource in KwaZulu-Natal.

Dissertation submitted in compliance with the requirements for the Masters Degree in Technology: Business Administration, Durban University of Technology, 2012. / The aim of this research project was to study the basic understanding the decision makers of construction companies in KwaZulu-Natal had of the Broad-based Black Economic Empowerment (BBBEE) initiative. This initiative has evolved from its origins as a form of affirmative action in the early 1990s into the broad-based initiative embodied in the Broad-based Black Economic Empowerment Act promulgated in 2003 and gazetted in 2007. Research was conducted using a questionnaire to assess the targeted population’s understanding of BBBEE. A census of the 259 construction companies affiliated with the KwaZulu-Natal Master Builders Association (NMBA) at the time of the research was used. The questionnaire was distributed primarily by email and the returns were assessed using statistical methods. The results were also tested as a cross-tabulation based on the demographics and the BBBEE rating of the respondents. The findings showed that although most of the respondents knew about the BBBEE initiative and indicated a level of understanding of this policy, certain of their perceived understandings were misguided. The way in which the Act was intended to be implemented and was intended to benefit those who were previously disadvantaged had been misread by all parties. The way in which the government has rolled out its BBBEE initiative has not been effective. This needs to be addressed by both training and partnering with those SMMEs that can most effect change to implement the Act. This study only scratched the surface of the effects the BBBEE legislation will have on small to medium-sized businesses. It has highlighted the need for further research into both the trickle-down effect of this initiative and into the availability of skilled personnel to grow the economy in the way the BBBEE Act intended.

Dissertation submitted in compliance with the requirements for the Masters Degree in Technology: Business Administration, Durban University of Technology, 2013. / This study explores the factors that limit the long-term survival and development of micro and survivalist enterprises of a selected informal sector in Durban, KwaZulu-Natal (KZN). Micro and survivalist enterprises play an important role in the South African economy, but despite their significance, several studies have shown that these enterprises fail within their first five years. The high failure rate is partially attributed to lack of support from external sources of support as well as the enterprises’ own internal weaknesses. The study was descriptive, exploratory and quantitative in nature. Questionnaires were used to gather data. The questionnaires were personally distributed at the business sites of the respondents. The respondents consisted of 108 micro and survivalist enterprises of a selected informal sector in Durban, who were selected by means of a non-probability sampling method. The results obtained identified a number of limiting factors for the selected informal enterprises’ long-term survival and development. The limiting factors, that are internal to the businesses, included: poor planning, lack of networking, insufficient business experience, poor pricing knowledge, managerial and business knowledge incompetence and lack of literacy, education and training. Those that are external to the businesses comprised of inadequate knowledge in terms of the institutional and supportive environment. Few respondents knew about financial and non-financial services and access to training and development programmes provided by government, semi-government and other institutions. As a result, recommendations to increase awareness of the different incentives available to micro and survivalist enterprises have been set.

Assessing the outputs and outcomes of wetland rehabilitation activities is recognised by the 'Working for Wetlands' programme in South Africa as important, but to date has been limited. An assessment of the ecological outcomes and the structural outputs of the Working for Wetlands rehabilitation implemented in the Killarney and Kruisfontein wetlands, KwaZulu-Natal, in 2005 was undertaken. The assessment of outcomes included an evaluation of the changes in terms of ecological integrity and the supply of ecosystem services, using WET-Health and WET- EcoServices assessment techniques respectively, and vegetation composition. Improvements in hydrological and geomorphic integrity were recorded in both wetlands, resulting in improved ecosystem services delivery. However, investigation of vegetation composition using the Wetland Index Value and Floristic Quality Assessment Index showed that, seven years after rehabilitation, KiNamey's vegetation composition had improved, but Kruisfontein's vegetation was still largely dominated by pioneer species and appeared to be stable, but in a severely transformed state. The response of these wetlands has shown that sites for rehabilitation should be screened before work begins, and wetlands requiring intensive management of vegetation recovery should be assessed in terms of the objectives and the anticipated benefits of the project. The assessment of the outputs included an evaluation of structural integrity, survival and cost- effectiveness. Limited issues, mostly relating to deviations from the designs during construction, were identified with regards to the structural outputs at each of the wetlands. However, the spreader canals at both Killarney and Kruisfontein wetlands were not functioning as intended and concentrated flows from the spreader canals were evident in both wetlands. The use of spreader canals should therefore be carefully planned and implemented for future wetland rehabilitation projects. Consideration of ZAR per hectare equivalent re-instated/secured provided a useful initial means of determining the cost-effectiveness of the wetland rehabilitation. However, additional factors need to be considered, such as, the nature of the rehabilitation activities, the type and size of the problem being addressed, rehabilitation of priority wetlands, limitations imposed by funders, and risks that need to be addressed by the rehabilitation strategy. Furthermore, the evaluation of the Killarney and Kruisfontein wetlands highlighted the need to revise the Water Research Commission's Wetland Management Series, especially those documents or guidelines relating to rehabilitation planning (WET-RehabPlan), interventions (WET-RehabMethods), and monitoring and evaluation (WET-RehabEvaluate).

Submitted in fulfilment of the requirements of the Degree of Master's in Public Management, Durban University of Technology, 2017. / The purpose of the study explores the perception and experiences of students regarding weapons in schools, in a bid to create a peaceful and conducive learning environment. This study concentrated on four high schools in Umgungundlovu District. Students, educators and principals were asked to participate in this study on a voluntary basis. The study recognises that existing data related to weapons in South African schools is largely anecdotal. The significance of the study is that it collected data related to the weapons in schools and used data to inform recommendations on ways in which we can make schools safer places to the young people and staff. This was a mixed methods survey; however, the bulk of the findings were drawn from the quantitative data, which was conducted through surveys. The qualitative data was collected in interviews and in focus group discussions. The data revealed that a high proportion of students have seen weapons in school, which might be an indication that weapons find easy access onto school premises. The results revealed the types of weapons brought to schools. Knives were the weapons most seen at school followed by guns, while some other weapons mentioned were pepper sprays, screwdrivers, pangas and bats The study showed that in other schools, drugs, alcohol, substance abuse were reported in the sample. Among the contributing factors raised by the respondents on the reasons for the presence of weapons onto schools were the issue of drugs, alcohol, bullying, fights among students, and being involved on gang activities. Some policy recommendations regarding school security measures were proposed on the basis of the findings which were drawn from this study. As part of the study, it is recommended that the Department of Education ensure that all South African schools implement well-documented discipline policies, a code of conduct and school rules for their school which must clearly indicate seriousness of carrying a weapon in school as well as the consequences of misbehaviour. The policy must have steps to be followed by the principals and or educators where there are elements of misconduct against the students and sanctions to be issued if the student is found guilty. Other recommendations were made in line with the findings based on the results. Limitations of the study were further pointed out. / M
