Environmental Education (EE) as a development cannot be ignored by Geography or Geographers particularly since South Africa, as the rest of the world, is confronted by a looming environmental crisis. Geography is an environmental science concerned primarily with man-environment relationships using an environmental approach to develop the skills, knowledge, values and attitudes necessary for sustainable living. Geography has a vital role to play in addressing environmental issues. In formal education Geography teachers will be responsible for the implementation of such an approach. This study therefore investigates the perceptions of Natal Senior Secondary School Geography teachers regarding the role of EE in Geography. Questionnaires and semi-structured interviews were used to determine this. The study revealed that although these teachers are well qualified and motivated they had a limited grasp of the theory underpinning current EE and Geographical thinking. Recommendations are made for the development of an environmental approach in the teaching of Geography.

A developmental paradigm was adopted as a theoretical base from which the effectiveness of the Natal Education Department Career Education lesson-guide in promoting career maturity amongst high school pupils was investigated. It was argued that careers education embodies a distinctive approach to careers work. This approach is described. South African Careers Guidance practices are evaluated in terms of fit, and are compared to American and British ones. To investigate the outcomes of the NED lesson guide, 160 predominantly white, male and female pupils in Standards 6 - 10 were randanly divided into control and experimental grotps and underwent a six session classroom based careers education programme. In addition to the NED material,alternative materials (CRIC - Std. 7 and CRAC - Std. 9) were used on a second experimental group in two standards. The Career Maturity Inventory Attitude Scale was used to measure the outcomes. Analysis of variance and t-tests for the difference between means were used to analyse the data. The results were significant only in Standard 8. For all the other standards with all the materials, they were insignificant. Reasons for and implications of these findings are discussed.

The shortage of nurses in any health care setting increases workloads and complicates workflow. In South Africa the shortage is exacerbated by multiple factors, one of which is the emigration of nurses to countries that offer better benefits and working conditions. The purpose of the study was to explore and determine the views of nurse managers regarding staff turnover and retention, and to recommend effective measures to improve the retention of nurses. The inquiry was conducted in a KwaZulu-Natal hospital, a natural setting for the participants. The study utilized a qualitative, explorative, descriptive design. The population of this study comprised of 36 nurse managers. Purposive and convenience sampling techniques were applied to select a sample of 18 nurse managers. Data were collected through focus groups. Data were transcribed and analysed thematically, emerging patterns were noted. The researchers examined these categories closely and compared them for similarities and differences. identifying the most frequent or significant codes in order to develop the prominent categories. These were summarised in a narrative form. Four themes emerged from the findings: the staff turnover challenge; current retention strategies; measures to improve retention and strengthening management. The shortage of nursing staff was critical at this selected hospital, and this situation could be considered to be a microcosm of what is happening in public health care sectors in South Africa. Various measures were put in place to curb the high turnover. However, these measures had a fair to low level of success. Therefore, improved retention strategies are required to reduce the staff turnover. It is evident from the findings that needs to be done to investigate, plan and implement effective measures that are likely to retain nursing staff and recruit more nurses into the profession. / Health Studies / M.

M.A. (Geography) / The development of a new airport usually brings with it the problem of aircraft noise pollution for land users located within about 15km of the airport boundaries. Excessive aircraft noise levels can cause health problems for residents and workers, and be responsible for a decrease in residential property values in the noise impacted areas. This dissertation reviews the problems associated with aircraft noise, examines the predicted noise impact of aircraft operations at the proposed airport at La Mercy in KwaZulu-Natal in South Africa, and concludes with recommendations for future land use around the airport. A number of relatively small urban settlements (Tongaat, Verulam, Waterloo, La Mercy, Umdloti Beach) are located around the La Mercy airport site. Almost all of the land not used for urban sett~ements is used for cultivation of sugar cane - very little land remains undeveloped. The agricultural land will probably eventually be converted to urban use, given the close proximity to Tongaat, Verulam and Durban. As such, comprehensive land use planning may still be done in order to avoid development of land for uses which will not be compatible with the anticipated aircraft noise levels. The Federal Aviation Administration's (FAA of the United States) computerised Integrated Noise Model (INM), designed to model aircraft noise impact was used to derive contours representing aircraft noise exposure around the airport. Taking factors such as airport elevation, mean temperature, runway usage, aircraft type, and flight routes into account, a set of contours unique to the airport at La Mercy were produced. By overlaying the noise contours on land use maps, land uses which would be incompatible with aircraft noise, should the airport be constructed were identified. Recommendations were then iii made on future developments in those non noise compatible areas. Much of Tongaat would be exposed to a moderate noise impact, whilst small portions receive a substantial impact. The whole settlement of Waterloo, and the southern portion of Verulam would be exposed to a severe noise impact. The central and northern portions of Verulam would receive substantial and moderate impacts respectively. Mount Edgecombe and Duffs Road would be exposed to a substantial impact, whilst the northern suburbs of Durban including Westville would encounter a moderate impact. An examination was then made of the general principles for land development - physical requirements of commercial, industrial and residential land use, and locational requirements of these land users in relation to one another. Thereafter, undeveloped land (undeveloped from an urban point of view ie. land used for sugar cane cultivation) was identified, and broad recommendations made for developing that land for urban use, taking general land use development principles into account

The study determined the impact of agricultural development projects on poverty alleviation at Amajuba district municipality. Data was drawn from 100 respondents, projects were purposively selected in line with the focus of projects members and non-projects members in Dannhauser under Amajuba District municipality to access and investigate the impact of agricultural development projects on poverty alleviation. The study presents the results of assessing those that are in groups and those that are working individually on agricultural production to alleviate poverty. The data was captured using a questionnaire which was administered through face-to-face interviews. Descriptive statistics and binary logistic regression model were used to analyse and compare the level of livelihood and variables between project and non-project members. The results show that project members are more productive than non-project members. Project members had more access to funding, training, markets and extension services compared to non-members. However, the results further showed that being a project member attracts some rewards which end up improving the living standards as well as alleviates the poverty levels of farmers, whereas working as an individual limits the farmer(s) from receiving reasonable government assistance such as funding and extension services delivery. The descriptive results indicated that members of most rural households were relatively old, married, literate but unemployed. Non-project members were dependent on remittances, social grants and pension funds because the farming strategy could not meet all their household needs. However, The major crops that were grown for income and food security to maintain their livelihoods include: maize, potatoes, onions, butternut, carrots, cabbage and dry beans. Factors that had significant influences on outcomes were extension services, grants, pension and remittances, land productivity, market accessibility, output difference and livelihood. The available opportunities for project members were access to land, funding, markets, infrastructure, inputs and support services from government institutions, as well as NGO’s.

M.Sc. (Zoology) / The construction of the Pongolapoort Dam in 1974 has altered conditions downstream of the Phongolo River in terms of hydrology, geomorphology, water quality, and ecosystem services. Activities along the Phongolo River permit anthropogenic compounds such as pesticides used in disease control to enter the aquatic environment. This alteration of natural environmental conditions creates a need for a monitoring programme. This study aims to assess the use of Hydrocynus vittatus as an indicator organism of pollution in the Nyamithi Pan and Phongolo River. Water and sediment samples were analysed for a variety of metal elements. The physical characteristics of water samples were determined using a WTW Multi 340i multimeter. Nutrients in water were analysed using a Merck Spectroquant™ Pharo 100 Spectrophotometer. Sediment analysis was based on the standard protocols of the United States Environmental Protection Agency (2001). Physiological stress responses in Hydrocynus vittatus were determined using acetylcholine esterase, catalase, cellular energy allocation, 7-ethoxyresorufin-O-deethylase, malondialdehyde, metallothionein, superoxide dismutase, and protein carbonyls. Employing standard techniques H. vittatus was analysed for metals and organics using ICP-MS, ICP-GS and ICP-OES. Results for biological responses and bioaccumulation show significant differences between sites related to the environmental concentrations of elements. Organisms in the Phongolo River have elevated concentrations of DDT and the metabolites indicating recent exposure. Organisms from the Phongolo River are seen to be responding based on up or down regulated concentrations of biological markers. In particular, concentrations of CAT, MDA and PC are elevated in the Phongolo population with decreased AChE responses indicating toxicant exposure. Data accumulated in this study will contribute to the establishment of baseline chemical, physical and biological knowledge of the effects of contamination in South African waters.

The supply of water to 'disadvantaged' areas of KwaZulu-Natal has in the past received low priority. Local government is now faced with supplying water to large, sometimes dispersed, rural populations. Groundwater has been utilised informally as a water supply for some years, but the impetus provided by the Department of Water Affairs and Forestry's White Paper has compelled those responsible for water supply to seriously consider groundwater as a sustainable option. The development potential or success of groundwater in its role as a reliable water supply is dependent on acceptance of the resource by the communities, appropriate level of service, yield sustainability and safe quality. Apart from the social aspects, the yield and groundwater quality characteristics of the aquifers under consideration must be used to determine the best hydrogeological features to target during exploration. A total of 993 borehole records, from a recent government drought relief programme, were used to compare the yield, water quality and best geophysical exploration and drilling techniques of the main hydrolithologies in rural KwaZulu-Natal. The results of comparative analysis shows that the competent rocks of the Natal Group and Natal Metamorphic Province and the karstic Uloa Formation of the Maputaland Group have the best overall potential for water supply. The unconsolidated sediments of the Maputaland Group also have good potential, but have some salinity problems. The Karoo Supergroup sediments and volcanics have moderate potential, with the argillaceous rocks having the worst potential of the Karoo rocks. The contacts between the Ecca Group shales and sandstone have the best potential of the Karoo Supergroup sedimentary hydrolithologies. Fractures clearly enhance the groundwater potential of most hydrolithologies, with fractured Dwyka Group tillites rated as having one of the best development potentials of all the hydrogeological targets in KwaZulu-Natal, despite the hydrolithology's poor water-bearing characteristics. Dolerite contacts with sedimentary rocks are commonly targeted features in groundwater development. However, the results from this research showed that, apart from the Natal Group's contact with dolerite, these targets have poor development potential. In general, contacts between different hydro lithologies. Health related quality was found to be adversely affected in argillaceous hydrolithologies, such as the majority of Karoo rocks which had high levels of sodium and chloride and Natal Metamorphic Province schists which had elevated sodium, chloride and fluoride. Crystalline and arenaceous hydrolithologies generally exhibited good quality groundwater. A comparison between the different geophysical methods for each target feature indicates that there are appropriate methods to use to detect anomalies related to water-bearing features. The large number of dry boreholes drilled in locations with recorded geophysical anomalies can be either a function of the water-bearing characteristics of the formation, human error or background noise. The cost of using the different geophysical methods vary considerably. The order of increasing cost is magnetics, VLF, EM-34, electrical resistivity profiling followed by vertical electrical sounding. Drilling has a large influence on the development potential of certain aquifers due to the high costs involved. Most of the secondary aquifers will require percussion drilling which is the cheapest method of drilling commonly used. Some very unstable formations within fractured or highly weathered rock may need ODEX drilling to enable drilling to advance. ODEX drilling in these conditions is very costly and can double the cost of drilling compared to air percussion. The unconsolidated sediments of the Maputaland Group can only be drilled by mud rotary or ODEX techniques. The relative costs of these two methods arer very similar with ODEX being slightly cheaper. Because of the high expense of drilling in the sands it is recommended that alternative sources, possibly from shallow hand-dug wells, be considered as appropriate methods of accessing groundwater. The aspects of groundwater yield and quality of aquifers, appropriate geophysical siting and drilling methods, together with social considerations will all contribute to the success of groundwater development in rural KwaZulu-Natal.

Submitted in fulfillment of the requirements for the degree of Master of Health Sciences in Emergency Medical Care, Durban University of Technology, Durban, South Africa, 2017. / Introduction: Response times are considered to be one of the oldest and most popular indicators which are used to measure the efficiency of Emergency Medical Services (EMS), particularly to cases in which the patient’s condition is deemed to be life threatening. Purpose: To analyse emergency response times within the public sector Emergency Medical Services in KwaZulu-Natal and to compare these to the national norms. Methods: Using a mixed method approach, the study was conducted in two phases. The first phase involved collecting quantitative data for all the cases logged in the Umgungundlovu Health District Communications Centre over a period of one week (seven days). Phase Two involved the collection of qualitative data from focus group discussions which were conducted with three groups which had been identified. These groups included the communications centre staff, operational staff and supervisory staff. The aim of these focus group discussions was to identify factors that influenced response times as well as to propose strategies which would improve these response times. Content analysis was utilised to interpret the qualitative data which had been collected. Results: Quantitative data was collected from a total of 1 503 cases of which 680 were categorised as priority 1 (P1), 270 as priority 2 (P2) and 553 as inter facility transfer (IFT). The majority of the cases (895) had occurred in urban areas. A total of 406 cases were exempted as no patient was transported. The number of these cases was greater on days when the total case load was higher as compared to days with a lower total case load. The mean response time to cases in rural areas was 129 minutes and 110 minutes to cases in urban areas. All the time intervals were found to be longer for cases in rural areas as compared to those for cases in urban areas but with the exception of the EMD response interval. P1 cases had the shortest mean response times for both urban area cases (33 minutes) and rural area cases (95 minutes) as compared to the other case categories. Nevertheless, the national norm of 15 minutes in urban areas and 40 minutes in rural areas was not achieved in the majority of the cases. The mean Emergency Medical Dispatch (EMD) response interval was 41 minutes for P1 cases, 56 minutes for P2 cases and 96 minutes for IFT cases. The qualitative data revealed factors that impacted on the response times and helped to explain and account for the quantitative data results. Challenges regarding the availability of resources, including vehicles, staff and equipment, as well as the way in which such resources are managed, were highlighted. The high demand for services compared to the available resources was raised by the focus group participants with this high demand resulting in extended EMD response intervals. This was exacerbated by the overwhelming demand for IFT cases which are serviced by the same resources as emergency cases and which have a much longer mission time, thus delaying response times continuously. Exempt cases were also found to impact negatively on response times as, although operational vehicles are committed to these cases, services are not required. Inconsistencies with regards to case prioritisation and dispatch triage also emerged. External factors, including poor road infrastructure, lack of road names and house numbers, weather conditions and long distances between EMS bases, the patient or incident location and health care facilities were also identified as factors that resulted in extended response times. Strategies to improve the situation were explored. These strategies included the effective management of resources in order to ensure optimal availability, the introduction of a formal, computer aided, dispatch system, the adoption of demand pattern analysis and dynamic location/relocation models, standardised processes and procedures to guide all areas of EMS operations and the education of both the public and staff. Conclusion: South African EMS response time national norms for both rural and urban areas are unachievable under the majority of circumstances and, thus, they may be said to be unrealistic. Until these national norms, against which the efficiency of EMS in South Africa is measured, are revised, the service will be deemed to be incompetent. / M

Gastropods are one of the most diverse species groups in mangrove habitats, however, many of their specific roles in relation to ecological patterns and processes are currently largely unknown. The overall aim of this research project was to provide basic ecological information for key gastropod species from subtropical mangroves within a protected area. South African mangroves cover relatively small areas and are restricted to estuaries, these habitats therefore present unique opportunities and challenges to the species that occur in them. Three gastropod species, Terebralia palustris, Cerithidea decollata, and Melanoides tuberculata, all occur at their natural southernmost range limit within South Africa and were selected based on their prominence and occurrence in mangrove habitats of the iSimangaliso Wetland Park, a UNESCO World Heritage Site. Trophic linkages and resource partitioning, resource utilization rates, and ecological resilience were investigated respectively using: 1) a stable isotope (δ15N and δ13C) approach; 2) an experimental approach to quantify feeding dynamics (ingestion rate, consumption/digestion efficiency and grazing impact); and 3) a mixed-effects modelling approach to relate population responses to environmental variables. The diet of T. palustris was seasonally variable and a number of sources were incorporated by different sized snails, but their grazing impact on microphytobenthos was not significant. The results also indicated an ontogenetic shift in the dietary niche for T. palustris through robust partitioning of resources between different size classes. The diets of C. decollata and M. tuberculata were dominated by different primary resources as a function of where they occurred in the mangroves. Melanoides tuberculata consumed a wide variety of primary resources, a typical trait of an opportunistic generalist species. The ingestion rate of M. tuberculata was not dependent on the availability of microphytobenthos, and was highest when conditions were oligotrophic. The resilience of C. decollata was related to the tree-climbing behaviour of this species and its occurrence was best explained by sediment conductivity. These responses were considered in conjunction to what has previously been reported on the resilience of the mangrove trees. The results of this research project have provided new basic ecological information for all three gastropod species in this data-deficient subtropical region. This information can potentially be used in comparative studies for these species in other regions or in broader scale ecological studies. Terebralia palustris has recently experienced a range contraction along the South African coastline. This research project has shown that the diet of this species is highly variable and that food limitation and competition for resources should be considered as potential drivers of the local decline. Cerithidea decollata has in contrast expanded its distributional range in this region. This research project has shown that this species has a generalist diet and exhibits traits in relation to tolerance that are expected to have facilitated its expansion into temperate saltmarsh habitats that occur in dynamic estuaries. Melanoides tuberculata is a globally invasive species, and as South African populations are within its native range, ecological information from this region is valuable as it can be used to investigate the potential ecological effects following introduction into new habitats beyond the native range. Biological drivers have a significant impact on mangrove ecosystem functioning, particularly in relation to recycling and the retention of organic carbon generated through primary productivity. Understanding the ecological linkages that maintain ecological functioning and stability is therefore an important step towards conserving and sustainably managing threatened ecosystems such as mangrove forests.
