In the environmental impact assessment (EIA) field, much attention is paid to the process leading up to the granting of an environmental authorization, but very little is given to what happens after the consent decision is granted. This study aimed to address this lack through the implementation of an EIA follow-up procedure in a region of the Eastern Cape Province, South Africa. Follow-up focused on assessing the amount of non-compliance with EIA consent conditions as well as the overall impact that projects had had on the environment. The results of this follow-up process were then used to develop a risk screening tool that could be used to screen out new EIA applications that were likely to require follow-up to control default or impact. Projects that showed the greatest amount of default were those submitted by local municipal proponents for basic infrastructure type activities such as sewage treatment works and low-income housing developments. Private companies that compete in the open market presented the lowest default risk. Default with consent conditions ranged between 0% and 100% with an average rate of default of 49%. The overall environmental impact for the majority (58%) of projects followed-up on was low (on a 5 point scale of low to high), with only 1% of projects scoring high on impact. The study found a moderate positive correlation between default and impact (rs = 0.48) although a significant percentage (39%) of projects scored high on default but low on impact. Follow-up appears to have had a positive effect on reducing the average amounts of default and to a lesser extent the degree of impact. The risk screening tool developed is promising with statistically significant matches between predicted and actual default and impact scores for three out of the four test samples. / Geography / D.

The Mogale’s Gate Biodiversity Centre is a 3 060 ha reserve located within the Gauteng province. The area comprises grassland with woodland patches in valleys and lower-lying areas. To develop a scientifically based management plan a detailed vegetation study was undertaken to identify and describe the different ecosystems present. From a TWINSPAN classification twelve plant communities, which can be grouped into nine major communities, were identified. A classification and description of the plant communities, as well as, a management plan are presented. The area comprises 80% grassland and 20% woodland with 109 different plant families. The centre has a grazing capacity of 5.7 ha/LSU with a moderate to good veld condition. From the results of this study it is clear that the area makes a significant contribution towards carbon storage with a total of 0.520 tC/ha/yr stored in all the plant communities. / Environmental Sciences / M.Sc.

As a sub-component of “green economy”, “the green transport” phrase is used interchangeably with eco-mobility, sustainable transport and clean transport. It has gained momentum as a way of addressing several socio-economic and environmental challenges associated with the conventional fossil-based transportation systems. Governments across the world have since developed policies and financial support mechanisms to pursue a greener transportation path. As a player in the global system, South Africa is expected to play a particular role. While research has been conducted in South Africa on various themes of transport greening, there seemed to be a lack of academic, integrated and comprehensive analyses of policy responses to these themes. This research thus sought to investigate and provide insight on the government’s responses to the transport greening revolution. It sought to benchmark this country against leading global players, making recommendations on policy directions for five transport greening themes: fuel quality, fuel economy, fuel switch, technology switch and non-motorised transportation. The aim was to contribute to the green economy body of knowledge, while assisting in guiding policy direction to enhance the country’s response system to the transport greening transition. Primary data were collected from interviews largely with representatives of key government departments at national and provincial levels as well as from attendance at various government and industry fora. Secondary data were obtained from policy, legislative and regulatory documents as well as official reports. Both primary and secondary data were analysed qualitatively using content analysis and presented using graphic, tabular and verbatim techniques. Using ideas borrowed from interventionist, systems, sustainability and globalisation conceptual frameworks, this research describes how South Africa is lagging behind the rest of the world in terms of transport greening policies and related financial and non-financial support mechanisms. Examples of good practice are nonetheless evident within the governance system. These include the adoption of globally accepted emissions and fuel economy standards, inclusion of transport greening agenda in various domestic legislative and policy frameworks, through to the exemption of certain transport greening products from import and local taxes. Many gaps still exist such as lack of incentives actively stimulating the demand and supply of green transport goods and services. This research therefore calls for more state intervention to address these gaps and strengthen existing policy and legislative frameworks. Due to the small sample of data sources used, the results are not generalisable, but nonetheless provide insight on green transportation and what South African policy makers should consider to improve the status quo. / Environmental Sciences / Ph.

The Clean Community System (CCS) is a method of waste management education widely used in the USA by the Keep America Beautiful organization. The CCS has been applied by the eThekwini Municipality since 1981. The training of staff and volunteers in the CCS has to date been limited and based on the American model. The aim of this study is to provide guidelines for the training of participants in the Clean Community System in the South African context. This will be achieved by a study of two community groups that have successfully applied the CCS. The results of the research will be compared with the principles of the CCS and relevant literature. The conclusions drawn from the study will provide guidelines for the training of participants in the CCS. / Further Teacher Education / M. Ed. (Didactics)

The increase in the number of guest houses is applausive for its socio-economic benefits through income generation, job creation and entrepreneurship growth. However, the increase in the number of guest houses is proportional to energy demand. Thus, increase in energy efficient guest houses is more desirable in order to achieve sustainable development. Therefore, the aim of this study was to assess energy efficiency in selected guest houses in Mpumalanga province Through in-depth literature analysis, an energy efficiency framework that builds on and advances the input-output ration and energy saving model was developed. This framework has five indicators which are categorised into financial and nonfinancial, namely: energy quantity, cost, carbon equivalence, services quantity and quality. The framework clarified the differences between energy saving and energy efficiency, while it identifies energy saving and services levels as two parameters or components of energy efficiency. This framework was later implemented and used to assess energy efficiency in eight selected guest houses in Mpumalanga province. To assess energy efficiency using the framework, three standard or common services in guest houses such as indoor lighting, water heating and indoor thermal comfort were assessed for energy saving and compliance with industry standards. The results of the assessment were analysed through descriptive statistical and explanatory methods. Using the framework, the study found that few of the selected guest houses did save energy in one or more of the standards services. However, some methods used in the guest houses were found to be highly costly and resulted in high energy quantity consumption and high carbon footprint. Thus, these methods failed the test for characterisation of energy saving methods. Furthermore, the study found that all indoor lighting services didn’t meet minimum industry standards for indoor lighting of 100lux. All water heating standards were compliant, while indoor thermal comfort standards differed among guest houses. Thus, none of the guest houses met the minimum criteria for characterisation as being energy-efficient. However, different services qualified. Hence, the findings confirm that the energy efficiency framework was effective and reliable in the characterisation of energy-efficient guest houses. This framework builds on and advances the input-output ratio and energy saving models previously used. / Environmental Sciences / PhD (Environmental Management)

Companies in South Africa who have implemented the ISO 14001 environmental management system have claimed that it offered benefits such as an improved environmental performance and a business advantage. However, to date the commercial benefits associated with ISO 14001 in South Africa have not been quantified so the claims of a financial advantage cannot be verified. This study therefore sought to assess the financial benefits accruing to various manufacturing enterprises in Kwa-Zulu Natal, the Eastern Cape and the Western Cape provinces of South Africa who have implemented ISO 14001. There was a particular focus on determining the cost savings and return on investment which resulted from the purchase of „environmentally friendlier‟ raw materials; the reduction of process waste (by the reuse, reduction and recycling of waste) as well as the more efficient use of resources such as electricity, water and fuel. Data was collected by means of a questionnaire survey sent to key decision makers in the selected organisations, as well as follow-up in-depth interviews with selected individuals within each organisation. The results of the study showed that the benefits of ISO 14001 certification included improved environmental awareness among employees; enhanced responsibility for environmental concerns by employees; better data management; reduced operational and production costs; and new income streams linked to re-use and recycling initiatives. Consequently it can be said that the long-term financial benefits justify the relatively high cost; the time intensive obligations and the human resource requirements of ISO 14001 certification. That said, it was also found that smaller companies face relatively more financial hurdles in implementing an EMS, and thus, it is recommended that tax incentives for such firms to implement and EMS be considered. / Environmental Sciences / M.

This study investigated the education and training needs for municipal employees in order to inform an education and training strategy that would address environmental management challenges in Makana local municipality in Grahamstown, Eastern Cape province. The research was conducted as a qualitative case study that made use of questionnaires, document analysis, focus group discussions and interviews as instruments for data generation. Samples of respondents were selected from Makana Municipality employees in top and middle management positions, professionals/technicians and workers, including elected councillors. The study was contextualised through establishing environmental management issues in Makana municipality; establishing organisational needs; development of a learner profile; and through a review of policies and recent trends in adult education. The study established that the Makana Municipality employees are most concerned with the following issues: sanitation; solid waste management; livestock management and fire management. These issues require primary environmental competences among all council employees (top and middle management, professionals and technicians, workers and councillors who work on part-time basis). The educational implications needed to respond to these issues also require an understanding of legislation. The study also established that technical education and training which includes planning, project management, and financial and budgeting competences are necessary amongst the management and professionals. These competences may enable them to develop capacity in environmental management. This study further established the need for social education which includes competences such as communication and social justice. These competences should be developed amongst members of the same group as they need to involve the community in management of the environment. This should enable the municipality to create job opportunities and help change negative attitudes.

It is projected that by 2025 three-quarters of the world’s population will live in the coastal zone. This is an alarming statistic, with a consequently significant impact on small coastal towns and the adjacent marine environments. Developing communities within the coastal zone of South Africa have proved to be a significant pollution source of storm water. Studies have shown that storm water that is deposited in the ocean will be trapped in the near shore marine environment causing poor seawater quality over a large distance. Furthermore, this can pose a significant threat to the health of recreational users and important marine ecosystems. In Jeffreys Bay storm water quality is thought to pose a threat to the maintenance of the international Blue Flag status for its beach. The aim of the current project was to investigate the main sources of storm water and subsequent marine pollution at Jeffreys Bay and to develop an appropriate management strategy using the integrated environmental management framework. In order to achieve this objective, it was also necessary to determine the current quality of water at various points within the catchment and near shore marine environment. Even though the storm water was found to be severely contaminated no evidence existed for a negative impact on the marine environment. None the less, a precautionary approach was adopted and a risk assessment employed in order to consider potential impacts on the marine and aquatic environment, human health and socio-economic welfare within the town. Significant sources of storm water contamination included grey water, domestic solid waste disposal and informal ablution. These significant aspects were investigated further and it was found that solid waste management in the catchment was poor with significant quantities of waste, primarily (76%) from domestic sources, being disposed of illegally. A study of sanitation management showed inadequacies where up to 58% of the residents from the informal settlements disposed of their grey water into open spaces. The ratio of residents to toilets in these areas was 28:1, therefore supporting the outcome of the risk assessment. Due to the fact that all the significant aspects were related to anthropogenic waste, an integrated waste management plan (IWMP) was developed that would not only facilitate the reduction of pollution of storm water, but would also allow for sustainable community-based development.
