There is increasing recognition of the links between air pollution and human health. Epidemiological studies have shown that there are numerous air pollutants that are associated with indoor energy use and with the production processes of industries, and most represent some sort of health implication. However, in-depth and fundamental knowledge of the health impact relationship of most pollutants is limited. This research evaluates the socio-economic and spatial aspects of the health implications of air pollution in Richards Bay (located 200 km north of Durban), KwaZulu-Natal. The research explores community perceptions and complaints relating to human health impacts emanating from air pollution in Richards Bay. The research is informed by a multi-conceptual framework (political economy incorporating political ecology, place perspectives and environmental justice) which influenced the methods chosen in conducting the research. Standard quantitative and qualitative methods were employed in the study to generate data relating to the research objectives. The process of triangulation which is the use of multiple methods that cuts across the qualitativequantitative divide was used. The various sources of information validate and clarify data by deepening and widening an understanding of the main issues under examination. The research was implemented in various communities in Richards Bay that reflect socioeconomic differences, which contributes significantly to ascertain whether health impacts are differentially experienced by different socio-economic groups. Furthermore, the research cross-tabulated experiences, perceptions and coping strategies of different socio-economic groups in the area, especially in relation to upper, middle and lower income clusters. The spatial aspect of the research (mapping of key social and health variables) is a major contribution of this research, which draws from the field of medical geography. Information on the main residential areas was illicitied from documents providing background details on Richards Bay. A purposive sampling approach was adopted to identify the seven communities, namely, Alton, Aquadene/ Brackenham, Arboretum, Meer-en-See, Empangeni Rail, Nseleni and Umhlathuze. Simple random point sampling was used to identify the households within the communities. The number of households in each community was determined using proportionate sampling. Four hundred and seventy nine housholds (479) were interviewed which was deemed to be a statistically relevant sampling size at a 95% confidence level. The study findings indicate that the lower income areas (Nseleni, Empangeni Rail and Umhlathuze) and the middle income areas (Aquadene/ Brackenham and Arboretum) have a more youthful population with a significant number being children, while the upper income areas (Alton and Meer en See) have a more elderly population. A similar trend was also found in relation to household size. There are clearly major variations in household income and employment types in Richards Bay, linked in part to the geographical location of communities based on economic and racial groups. Lower earning respondents were located mostly in the lower status areas which were classified as predominantly African populated areas as per the historical race classification and apartheid segregated areas. More than half of the respondents indicated that industrial smoke was the cause of their present health conditions. Other stated reasons were wide ranging and therefore there was no discernible pattern that emerged in relation to the causes for poor health experienced by the affected household member. However, the data did show that more respondents living in middle/ upper income areas identified causes. Reported health conditions include allergies (30.9%), coughing (29.8%), wheezing (25.5%), chest pains (18.4%) and asthmatic bronchitis/ asthma (17.7%). With regards to health care, the findings from the study show that the economically better off communities (Alton, Aquadene/ Brackenham, Arboretum and Meer en See) used the private, more expensive health care sector while generally households in lower income areas tend to rely on public or traditional health care facilities. An interesting finding was that most respondents rate their general health status as either excellent, good (more respondents from the middle/ upper income areas than the lower income areas) or satisfactory (more respondents from Umhlathuze). A large majority of the respondents reported air pollution as the main problem that is associated with industries in Richards Bay while the health impacts of pollutants from the industries manufacturing processes was the second main cause. The areas deemed to be the most polluted were generally in or in close proximity to the industrial area or the port area. Lower income areas tendered to be most polluted, according to respondents residing in these areas or who lived in similar low income areas. The majority of respondents were found to be living in dwellings/ households made from dwellings constructed with brick and asbestos, brick and zinc, stone and other traditional materials which is indicative of housing in the poorer communities who live in informal dwellings/ households and may be a causal contributing factor of the poor health status of these communities. The participatory mapping exercise conducted during the focus group discussion revealed that participants identified the industrial areas (including the port and surrounds) as the most polluted areas. Areas outside Richards Bay were considered to be the least polluted areas. The research findings indicate that there are a complex mix of socio-economic, environmental and spatial dynamics that influence air pollution and health impacts. Thus, health issues in the context of widespread air pollution concerns are linked to social, political and environmental aspects that require urgent attention. Air pollution and health impacts remain major concerns in many parts of the world, especially in areas of high levels of industrial development such as Richards Bay. The results of this research, therefore supports the findings of other researchers who reveal that communities/ neighborhoods of lower income status are most likely to bear the brunt of negative impacts and that air pollution from indoor uses of energy, behavioral factors such as cigarette smoking and industrial processes contribute to an individual’s/ community’s quality of life. / Thesis (Ph.D.)-University of KwaZulu-Natal, Durban, 2013.

The industrial port of Richards Bay on the eastern seaboard of KwaZulu-Natal, South Africa has undergone rapid growth over the last 25 years. This industrial growth has inevitably led to an increase in the anthropogenic pollutant inputs in the area. However, the degree of this contamination has not previously been assessed not been accompanied by an awareness of its environmental impacts. This project serves to assess the current environmental situation of the area and provide background levels against which the environmental impacts of further growth in the area can be assessed. The main pollution point sources in the area were identified as a pulp and paper plant, a sulfuric acid/fertiliser plant and aluminium smelters. The chemical and physical processes involved within these industries were identified and discussed in detail. The common inorganic pollutants emitted by these industries were identifies as trace metals, sulfur dioxide, NOx gases and fluoride. It was these pollutants that therefore became the focus of this study. Reservoirs within Richards Bay that may become sinks for contamination were identified and water, sediment and soil samples were taken from these reservoirs. The samples were analysed for trace metal contamination, pH, alkalinity and fluoride levels. Analysis of the acidity and alkalinity of water, sediment and soils samples demonstrated that there is presently no long-term acidification of the environment in Richards Bay. The only samples that showed increased acidity were the soils taken from the roadside sites immediately outside the industries. This lack of overall acidification indicates that, at present, there are no detrimental effects of acidic emissions on the hydrosphere and geosphere. Only cursory investigations were conducted into the fluoride levels found in water samples. None of the samples analysed demonstrated detectable amounts of fluoride present. Comprehensive trace metal analyses were performed on the water, sediment and soil samples through the use of ICP-AES. Levels obtained were compared with levels from samples taken from relatively uncontaminated background sites. Trace metal analysis indicated contamination of the freshwater reservoirs when compared with the background, while the soils and saltwater reservoirs remain largely uncontaminated. However, the contaminated areas did not show levels greater than quality guideline concentrations. Further studies should be conducted with regards to the trace metal contamination of the biosphere and the bioavailability of the contaminants already present in the waters, sediments and soils. More detailed investigations should also be conducted into the levels of atmospheric pollutants and fluoride levels in all reservoirs. / Thesis (M.Sc.) - University of KwaZulu-Natal, Pietermaritzburg, 2004.

Section 153 of the Constitution of South Africa (RSA, 1996) states that “a municipality must structure and manage its administration, budgeting and planning process to give priority to the needs of the community and to promote the social and economic development of the community”. Despite this mandate placed on local government, De Wet and Moseki (2015, p. 61) write that insurgent South Africans engage in violent protests against continued “municipal ineffectiveness in service delivery, poor responsiveness to citizens’ grievances, and a conspicuous consumption entailed by a culture of self-enrichment on the part of councillors and staff”. The Department of Corporate Governance and Traditional Affairs (COGTA ) (2014) identify huge service delivery backlogs, poor communication and accountability relationships with communities, corruption and fraud, poor financial management and insufficient municipal capacity as a result of lack of scarce skills as some of the priority areas impacting hardest on the municipality’s ability to function as a well-performing municipality. Mpofu and Hlatywayo (2015) report that poor performance by workers in local government has been established as one of the major issues affecting the efficient provision of municipal services by municipalities. It thus follows that the performance and conduct of municipal employees need to be improved in order to improve the delivery of basic services to the communities they are to serve. Hanyane and Naidoo (2015) hold the view that without proper service delivery, the achievement of good governance and the effective use of public resources will remain elusive. The primary objective of this study was to contribute to improving the levels of service delivery at a selected municipality by identifying which factors the employees of the municipality consider most effective in improving their levels of service delivery within the organisation. A questionnaire was structured and used to conduct a survey with 65 middle-level managers, senior-level supervisors, middle-level supervisors and operational staff.The study concluded that talent management and retention strategies were the only independent variable that proved to have a significant positive relationship with service delivery within the selected municipality.

Focusing on the policy context for social entrepreneurship in Nelson Mandela Bay Municipality (NMBM), this dissertation examines the processes through which social entrepreneurs participate in the processes of development of the municipality because; social entrepreneurship is increasingly being recognised as a mechanism for creating social and economic value. Social entrepreneurs play a significant role in fulfilling unmet societal needs and in filling gaps, particularly in areas where government and the market fall short. Based on this view, this study raises questions about the integrated policy guiding social entrepreneurship for better development outcomes. It aims to contribute to the body of literature on social entrepreneurship and development by examining the processes through which social entrepreneurs participate in the development of the communities at the local level. Using the Grounded Theory method, this study found that there is no integrated policy on social entrepreneurship in the NMBM and that the deficiency created by the lack of an integrated policy engenders Social Revisioning. The substantive theory of Social Revisioning emerged from the data to explain the processes through which social entrepreneurs participate in the development of communities when there is no integrated policy on social entrepreneurship. In response to the deficiencies in the policy context, differentiated and autonomous entities within and outside of the municipal government step in and support social entrepreneurs to provide services and participate in the processes of development. However, even though Social Revisioning can be used to address the policy deficiencies in social entrepreneurship and development, the differentiations and autonomy that characterise the entities, role players and processes embodied in Social Revisioning prevent cohesion among them and again beg for an integrated policy that will incorporate them.

As a clinic supervisor overseeing a cluster of clinics in the Nelson Mandela Bay Health District (NMBHD), the researcher observed a number of problems with the implementation of the re-engineering of the primary health care (RPHC) programme. The problems observed include inadequate supervision of RPHC staff, poor communication and conflict between clinic and RPHC staff, failure to filter RPHC statistics into clinic statistics and the incorrect management of patients by RPHC staff. Therefore, the purpose of this study is to explore and describe the experiences of professional nurses regarding the implementation of the RPHC programme in the NMBHD and to make recommendations the district manager could use to address the research findings. The study used a qualitative, exploratory, descriptive and contextual design. The research population consisted of professional nurses who are implementing the RPHC programme in the NMBHD, and the sampling technique was a non-probability, purposive technique for the selection of the research sample. Semi-structured interviews were used to collect the data and Tesch’s model respectively. The researcher adhered to ethical considerations throughout the study and ensured trustworthiness of the data by using the criteria of credibility, transferability, dependability and conformability. Three themes were identified; namely; the professional nurses expression of their concerns regarding poor working conditions; issues regarding the community health workers and their positive experiences associated with the RPHC programme. The study concludes with recommendations made to the District manager with regard to nursing practice, as well as recommendations to nursing education and research.

Thesis (MTech (Public Relations Management))--Cape Peninsula University of Technology, 2016. / The history of public relations include facets of “publicity” and “press agentry,” and has matured beyond these narrow, tactical functions, rising to accept positioning as strategic communications which can drive corporate social responsibility decision-making that resonate credibly with community stakeholder. The study explored public relations models of communication within stakeholder engagement to establish corporate social responsibility projects in the mining sector in Richards Bay, South Africa. The stakeholder engagement process depends greatly on principles outlined in the King Reports, which includes a stakeholder ‘inclusive approach’ and ethical guidelines for ‘governing stakeholder relationships’ and emphasises ‘sustainable development’. Furthermore, a socially responsibility business integrates the economic, legal, ethical and discretionary obligation of business to society and further recognizes its place in the broader community. Although qualitative research design was chosen for this study, the research used purposive sampling to select individuals and groups for data collection on the stakeholder communication experience. Six Individual in-depth interviews and one focus group interview were conducted with the organisation’s Communities and Corporate Relations team and the community leaders. The research reports that the corporate social responsibility stakeholder engagement process has five stages (consultation, engagement, agreement, decision making and feedback) and there is an evaluation process on community development projects set by the organisation. Consequently, the organisation and the communities both benefit from the corporate social responsibility projects. Additionally, the analysis shows that the model used for stakeholder engagement within corporate social responsibility is the mixed-motive model of public relations. Hence, the relationship between the organisation and its host communities is established and maintained, as well as the social licence to operate and reputation is enhanced. Therefore the research concludes that a public relations’ mixed-motive model of communication is best suited for stakeholder engagement in order to establish corporate social responsibility projects in the host communities that can enhance favourable organisation-community relationships. The model intends to achieve equilibrium between the organisation and the community stakeholder. However, further research is recommended into the development of a new African public relations model of communication that encompasses the concept of ‘Ubuntu’ where the community leader is the final decision maker in consultation with the traditional council.

In this economically challenging era, companies have got to find the best system that can help to enhance productivity. A very important method is by encouraging takeholders through various forms of incentives. The gain-sharing incentive has been adopted by many organisations today to enhance staff loyalty and productivity. A gain-sharing programme ensures that both the organisation and team members benefit from the expected performances, rather than an individual or group incentive which is given based on a specific finite goal which could be achieved at the cost of other key critical business need. A couple of years ago Autocast Aluminium decided to enhance employee performance by initiating the gain-sharing incentive programme. After the programme was rolled out, the organisation is yet to examine the extent to which it enhances job satisfaction in the organisation. The primary objective or aim of the study is to examine the extent to which gain-sharing at Autocast meets the purpose for which it was created. The sample of the study was 176 of the employees at Autocast Aluminium; however 130 questionnaires were distributed. A total of 88 questionnaires were returned, of which 80 were usable, whilst eight were scrapped due to more half of the questionnaire having missing data. This resulted in a 68 % response rate. A framework has been developed to measure to what extent does the programme enable employees to feel satisfied with their jobs. The empirical results revealed that out of six independent variables tested: fair payment, involvement, personal growth, communication, job security and leadership style, only three that plays significant role on employee job satisfaction. These are fair payment, communication and leadership style.

Recruitment of planktonic larvae into sedentary benthic populations regulates the population dynamics of marine invertebrates. The processes controlling recruitment, however, are poorly understood, and recruitment remains largely unpredictable, which complicates management of exploited shellfish resources. The mussels Perna perna, Choromytilus meridionalis and Mytilus galloprovincialis, found on the south coast of southern Africa, have planktonic larvae and sedentary adult stages. This thesis examines dispersal, settlement and early post-settlement growth and mortality, and their effect on recruitment and demography of intertidal mussel populations in the region of Algoa Bay on the south coast of southern Africa. Temporal and spatial variation in the body mass, density and size structure of mussels, the distribution of bivalve larvae on plankton grids in the nearshore zone and the distribution of a recently introduced invasive mussel, Mytilus galloprovincialis, were examined between 1989 and 1992. Furthermore, data on hourly or daily changes in wind strength and direction, air and sea surface temperatures and low and high tide levels in the study region, were obtained. There were 3-4 peaks in spawning (characterised by an abrupt decline in weight) and settlement activity annually. These peaks varied in exact timing, intensity and duration between sites and over time. However, at a site, spawning was followed by settlement 4-8 weeks later, and there was a significant (P < 0.05) direct correlation between spawning intensity prior to the appearance of a new cohort and the cohort density (settlement intensity). The stochastic spatial and temporal variation in breeding activity was superimposed on a more general pattern of a higher intensity of spawning and settlement in Algoa Bay than on the open coast, and a higher settlement intensity on coastal sandstone shores than on dune rock shores. Spawning was more frequent in winter and spring, and the probability of spawning and settlement peaked around the spring and autumn equinox, if temperature and wind conditions were suitable. Larval behaviour had little effect on their dispersal in the well-mixed nearshore region. Larvae were passively dispersed by currents, and their dispersal range and direction depended on prevailing winds and local topography. The sharp decline in density of recruit and adult M. galloprovincialis with increasing distance from the point of introduction, showed that some larvae were carried by wind generated currents over moderately long distances (-100 km). However, since most (76 %) M. galloprovincialis recruited within 4 km of the parent population, it is possible that larvae become trapped in small gullies and crevices around rocky shores, and have a limited dispersal range. This could explain the link between local patterns of spawning and settlement. The distribution and abundance of settlers on the shore was influenced by larval behaviour and the availability of settlement, substrata. Larvae preferred to settle primarily on foliose coralline algae and migrate to the adult mussel bed when they were larger (0.60-7 mm), but larvae also settled directly on adult mussels, possibly because the amount of coralline algae was limited. Both direct and secondary settlement were considered to be important in maintaining mussel populations since the rate of settlement was low(generally < 60 000.m-2). Cohort analyses showed that prior to maturity post-settlement growth (- 30 mm in 10 months) and mortality rates (60-100%) were high, but varied. When settlement intensity was low this variability uncoupled the relationship between spawning and recruitment intensity. Multiple regression analysis showed that together reproductive effort (gamete output), settlement intensity, growth and mortality prior to maturity, accounted for 76 % of the variance in recruitment into mature adult populations. The low settlement rate coupled with the short life span of mussels « 3 years), meant that populations underwent marked spatial and temporal variations in structure and abundance as settlement intensity varied, but there were consistent general differences between mussel populations on dune rock and sandstone shores in Algoa Bay and on the open coast. It was concluded from these results that, spawning intensity and post-settlement growth and mortality, rather than dispersal, regulated recruitment and the structure and abundance of intertidal P. perna and C. meridionalis populations along the south coast of southern Africa. On the basis of these results it is recommended that species with limited dispersal, variable recruitment and high natural mortality, such as P. perna, should be conserved by protecting a small part of the population in reserves, and controlling utilisation outside reserves to minimize disturbance to local brood stocks. Furthermore, since the potential for reseeding adjacent exploited areas is limited, several small reserves placed at regular intervals along the coast would be more effective than a single large reserve.

Sodwana Bay, situated within the iSimangaliso Wetland Park, is ecologically important as it contains high-latitude corals and the most southerly known population of coelacanths. This thesis utilised stable isotope and lipid analyses to investigate the trophic ecology of the area, in particular, understanding the relative contribution of inshore and offshore primary production to consumers inhabiting intertidal and shallow subtidal, coral reef, deep reef, canyon head and pelagic habitats. Seaweeds, excluding certain species of red seaweeds with highly depleted carbon signatures, and phytoplankton, such as diatoms, were found to be the principal sources of primary production for all consumers. Offshore production was typified by dinoflagellates. Particulate organic matter (POM) was spatio-temporally variable. Three distinct productivity periods related to nutrient cycling were noted with enriched carbon signatures and higher organic matter loads associated with warmer water. Inshore primary production was an important source of carbon to consumers in all habitats with the exception of zooplankton that were more reliant on pelagic primary production. Benthic invertebrates reflected a gradient in the utilisation of inshore production, due to the reduced availability of this source further offshore. Consumers at the furthest sites offshore were found to include a substantial quantity of inshore-derived production in their diets. Fishes, which are more mobile, were found to incorporate a similar proportion of inshore production into their diets regardless of where they were collected from.
