This thesis identifies the causes of disputes between scientists who are involved in environmental impact assessment and management (EIAM), and suggests some critical elements of scientific dispute resolution processes, particularly peer review. It does this within the context of a case study, the environmental assessment, monitoring, and management of the Island Copper Mine marine tailings discharge into Rupert Inlet, B.C. The events of this case are analysed, drawing on literature on the scientist's role in impact assessment and management, and on the philosophy and sociology of science literature. The case study and literature review indicate that the causes of such scientific disputes are complex. The complexity and uncertainty of the physical and biological processes of a fjord system are one cause. Logistical failings in integrating scientists into the process are another: poor timing of scientists' efforts; failures of communication; and lack of accountability are examples. Poor methodology and inadequate research design also caused disputes. The transdisciplinary nature of the scientific problems common to EIAM causes disagreements of a different nature-- over the relevance of various disciplines' research foci to the problem at hand, and over what constitutes acceptable scientific practice. Value and interest conflicts between scientists, which influence both the trajectory of research and the interpretation of its results, complete the typology of the causes of disputes. The thesis recommends the elements of peer review processes necessary to resolve these disputes. Peer review should be pre-emptive, by focussing on research design where possible, and should be representative of the range of relevant scientific disciplines, and should facilitate constructive solutions rather than the defense of positions. / Applied Science, Faculty of / Community and Regional Planning (SCARP), School of / Graduate

Bibliography: pages 105-107. / This dissertation forms part of the requirements for the degree of MSc in Environmental Science and was supervised by Professor R Fuggle, Head of Department of the Department of Environmental and Geographical Science. The dissertation describes and examines the practical application of integrated environmental management (IEM) by analyzing a case study. IEM is a methodology developed in South Africa under the direction of the Council for the Environment, the purpose of which is to incorporate environmental considerations into all aspects of planning and development. A guideline document on the implementation of IEM was published in 1989 (Council for the Environment, 1989(A)), and later updated and a set of six guideline documents was published in 1992 (Department of Environment Affairs, 1992 (A) to (F)). The case study is the proposed development of a rock quarry in a peri-urban area near Johannesburg, South Africa. It was implemented in accordance with the original version of lEM. The availability of the updated guidelines and the experience gained in the case study provided potential for comparison between the original and updated procedures. Other points of relevance regarding the case study are that the site is situated in a rapidly developing area, and could therefore cause significant social impacts; the study was conducted at the most detailed level of the original IEM procedure (Class 1 ); and involved public participation, which has been emphasised in the updated IEM procedure.

A research report submitted to the Faculty of Science, University of the Witwatersrand, in partial fulfilment of the requirements of the degree of Master of Science. Johannesburg, 2016. / This study evaluates the Environmental Impact Assessment (EIA) practice in the South African energy sector against a criteria developed by the researcher to determine the extent to which the EIAs contribute towards sustainable development. A questionnaire survey was conducted to gather information on the performance of the EIA practice of Eskom, which in this study represents the energy sector of South Africa. A review of the quality of a sample of EISs was also done against the modified Lee and Colley review package. The study revealed some strengths and weaknesses of EIA, as practiced by Eskom. The strengths include effective mitigation, public participation, training and the use of resources within ecological limits. The EISs were found to be generally of satisfactory quality. The weaknesses which limit EIA in the energy sector to reach its full potential in promoting sustainable development include inadequate monitoring, inadequate consideration of cumulative impacts and alternatives and inadequate engagement with community members directly affected by development projects on a personal level. Despite these weaknesses, the study concludes that EIA in the energy sector contributes, to some extent, towards the promotion of sustainable development.

Thesis (M.Sc.)--University of the Witwatersrand, Faculty of Science, School of Environmental Sciences, 2017. / Public participation in environmental impact assessments has been the subject of many studies around the world. The effectiveness of the public participation process in a South African context has however not been tackled by many authours. A study was conducted in order to assess the effectiveness of the public participation for environmental impact assessments in South Africa. In order to achieve this, 20 environmental impact reports were scrutinised, key informant interviews were conducted and analysis of legislation, regulation as well as applicable Guidelines was carried out. Results indicated that public participation in environmental impact assessment regulation fall short of addressing what the principles of the law states. Consequently, there is a need for the review of regulation to prescribe the involvement of marginalised groups through additional participation such as public meetings in the appropriate language as well as ensuring skills development to aid in effective participation. The inclusion of the monitoring of the implementation of the environmental management programmes as well as the inclusion of public participation in this process and therefore the life cycle of the project will aid in ensuring that the public has access to decision making. / XL2018

This research focuses on effective decision-making for sustainable manufacturing design and management. The research contributes to the decision-making tools that can enable sustainability analysts to capture the aspects of the economic, environmental and social dimensions into a common framework. The framework will enable the practitioners to conduct a sustainability impact analysis of a real or proposed manufacturing system and use the outcome to support sustainability decision. In the past, the industries had focused more on the economic aspects in gaining and sustaining their competitive positions; this has changed in the recent years following the Brundtland report which centred on incorporating the sustainability of the future generations into our decision for meeting today's needs (Brundtland, 1987). The government regulations and legislation, coupled with the changes in consumers' preference for ethical and environmentally friendly products are other factors that are challenging and changing the way companies, and organisations perceive and drive their competitive goals (Gu et al., 2015). Another challenge is the lack of adequate tools to address the dynamism of the manufacturing environment and the need to balance the business' competitive goal with sustainability requirements. The launch of the Life Cycle Sustainability Analysis (LCSA) framework further emphasised the needs for the integration and analysis of the interdependencies of the three dimensions for effective decision-making and the control of unintended consequences (UNEP, 2011). Various studies have also demonstrated the importance of interdependence impact analysis and integration of the three sustainability dimensions of the product, process and system levels of sustainability (Jayal et al., 2010; Valdivia et al., 2013; Eastwood and Haapala, 2015). Although there are tools capable of assessing the performance of either one or two of the three sustainability dimensions, the tools have not adequately integrated the three dimensions or address the holistic sustainability issues. Hence, this research proposes an approach to provide a solution for successful interdependence impact analysis and trade-off amongst the three sustainability dimensions and enable support for effective decision-making in a manufacturing environment. This novel approach explores and integrates the concepts and principles of the existing sustainability methodologies and frameworks and the simulation modelling construction process into a common descriptive framework for process level assessment. The thesis deploys Delphi study to verify and validate the descriptive framework and demonstrates its applicability in a case study of a real manufacturing system. The results of the research demonstrate the completeness, conciseness, correctness, clarity and applicability of the descriptive framework. Thus, the outcome of this research is a simulation-based impact analysis framework which provides a new way for sustainability practitioners to build an integrated and holistic computer simulation model of a real system, capable of assessing both production and sustainability performance of a dynamic manufacturing system.

There is concern that canyoning, which has grown in popularity in recent years, may not be environmentally sustainable within the Blue Mountains National Park. Sociomanagerial research was undertaken, using an initial focus group discussion and subsequent surveys. Canyoners were found to participate in their sport predominantly in small groups in relatively few canyons, were generally experienced, did not feel crowded by other people encountered, and displayed little evidence of displacement behaviour from popular locations. No specific biophysical impacts were perceived as serious. Canyoners generally supported management action to control visitation to canyons if overuse could be demonstrated, with education and/or restrictive actions as preferred management strategies. Biophysical research was undertaken to test a potential rapid assessment bioindicator for measuring and monitoring potential visitor impacts. Macroinvertebrate data were analysed and no significant difference in macroinvertebrate assemblage composition or water quality was found between high and low visitation streams. Macroinvertebrate fauna were found to be highly resilient to trampling. Current visitation levels within the canyons appeared to be within ecologiocally sustainable levels. The implications of the findings are discussed for visitor impact management policymaking. / Doctor of Philosophy (PhD)
