Critical review of the quality of environmental authorizations in South Africa / Andrew Brian Caddick

Caddick, Andrew Brian January 2015 (has links)
This dissertation critically reviews the quality of South African environmental authorisations through the application of a methodology adopted from the Lee and Colley (1999) environmental impact assessment (EIA) report review package. The literature review shows that to date limited research has been conducted on the quality of environmental authorisations nationally. Anecdotal evidence suggests that environmental authorisations are of weak quality; hence the development of guidelines on the compilation of environmental authorisations by the Department of Environmental Affairs (DEA). In this dissertation, the quality of the environmental authorisations is critically reviewed against the requirements of the National Environmental Management Act (Act No. 107 of 1998) and departmental guidelines. The research concludes that only 64% of reviewed authorisations are deemed satisfactory, while 36% were unsatisfactory. When the basic assessment report (BAR) and scoping and environmental impact assessment (S&EIA) process authorisations are compared it is concluded that the there is a minimal difference in quality. The BAR achieved a 69% satisfactory rating while the S&EIA process achieved a 61% satisfactory rating. The dissertation concludes by making recommendations to improve the quality of authorisations. / M (Environmental Management), North-West University, Potchefstroom Campus, 2015

A critical evaluation of the extent to which sustainability was considered in the Medupi power station / Melini Hariram

Hariram, Melini January 2015 (has links)
Sustainable development is described by the World Commission on Environment and Development as ―development that meets the needs of present without compromising the ability of future generations to meet their own needs‖. Sustainability assessments are an integrative process and framework for effective integration of social, economic and ecological considerations in significant decision-making processes. Sustainability is incorporated into South African legislation such as the Constitution of the Republic of South Africa (1996), the National Environmental Management Act (Act 107 of 1998), as well as Environmental Impact Assessment (EIA) Regulations. Despite the existence of such legislation, the challenge lies in the effective implementation of the EIA process, which has been identified as a useful tool in striving towards achieving sustainable development. This research uses Gibson‘s eight sustainability principles and Gaudreau and Gibson‘s sub-criteria to develop a case specific set of sustainability criteria for coal fired power stations in South Africa. The energy generation sector is a major source of social and environmental impacts. Coal power stations contribute to environmental degradation such as reduced air, water and land quality. This industrial process impacts on the environment and therefore needs to strive towards sustainable development by considering these criteria during the EIA process. The set of case specific sustainability criteria for power stations was then used to evaluate the EIA developed for Medupi Power Station in South Africa in order to assess, the extent to which sustainability was considered in the EIA process. The key finding is that sustainability is incorporated into South African legislation hence no change in legislation is required. Despite the existence of legislation, the challenge lies in the fact that is it not always effectively implemented. The EIA process is seen as a tool that can effectively deliver sustainability outcomes. However this process is not effectively utilised. In order for the EIA to consider sustainability the focus needs to be on the following criteria: Intragenerational Equity; Precaution and Adaptation for Resilience; as well as Immediate and Long term Integration, as these were recognised as weaknesses after the evaluation process. The recommendation is also to develop a set of case specific sustainability criteria for other large industries that have significant environmental impacts. / MSc (Environmental Management), North-West University, Potchefstroom Campus, 2015

Public participation in environmental impact assessment : an effective tool for sustainable development a South African perspective (Gautrain)

Aregbeshola, Maryam Titilayo 03 1900 (has links)
The need for public participation in the development of policies, programmes or actions has been widely accepted by both government and private sectors because of the benefits of such involvement. Involving the public in the development of any policy, programme or action is, however, a daunting task. Public involvement in the development of a policy or action often leads to protest, legal litigation, criticism and delay in carrying out the project. The main objectives of this research are to examine the process of public participation in the Gautrain project and to interrogate how public involvement in the decision-making processes of environmental concerns can be improved. A quantitative study was conducted to describe and explore the process of public participation in the Gautrain environmental impact assessment procedure. The purposive sampling method was used. Thereafter, the data generated was analysed using statistical tools such as charts, tables and the Wilcoxon Mann Whitney U test to examine the similarities and differences in the response patterns of the public and the project proponent. Cronbach alpha statistical methodology was also used to test the reliability of the measurement. The findings are discussed in relation to the objectives of the study and research hypotheses. The results indicate that (1) the public were not involved early enough during the project planning and design phases; (2) adequate information was not provided to the public; and (3) public input does not have much impact on decisionmaking processes. The study does, however, indicate that the process has enhanced the participants’ learning and that the process of participation has improved in recent time as compared to the 2002-2003 periods. The study concludes by providing relevant solutions and recommendations. / Environmental Sciences / M. Sc. (Environmental Management)

Incorporation of Sustainable Development Concerns in Regulatory Impact Assessments

Ritzka, Martin Stefan January 2016 (has links)
Regulatory Impact Analyses (RIA) are carried out in order to determine how a project or regulation affects the economy, society and environment. Traditionally, RIAs are carried out through cost benefit assessments and by monetizing different variables in order to assist policymakers with their decision. The main disadvantage of it, is that highly relevant social and environmental factors are difficult to quantify, thus providing weak or "incomplete" support to policy-makers in their final decision and enabling long-term consequences. An option to improving RIAs, is by taking into account such factors with the introduction of Sustainable Development (SD) concerns early in the decision making process. This is a trend that has been gaining more momentum and support, especially in OECD and EU members. The shift towards the inclusion of such concerns at a regulatory and legislative level nonetheless still presents itself to be a challenge and has wide room for improvements. On this research, four different countries and the European Union are analyzed and compared, presenting their current RIA practices and how much they take into account sustainability concerns with the intent on showing where can they be improved and better included.

Engineered landscapes: re-thinking sacrificed landscapes in the Canadian Prairies

Abdulrehman, Saira 21 January 2016 (has links)
The outcome of this practicum is the design of an "engineered landscape" that can anticipate, reveal and compensate for disturbances brought on by the Energy East Pipeline on local ecologies and communities.This practicum makes an argument for the increased consideration of qualitative values in contemporary landscape mitigation practice. The increased focus on qualitative values in landscape mitigation combined with the provision of facilities and landscapes necessary to build knowledge, skills and resources will result in landscapes and spaces that facilitate the empowerment of communities as stewards of the environment in the face of globalized industrialization and decreased federal/provincial funding. / February 2016

Bed filters for phosphorus removal in on-site wastewater treatment : Removal mechanisms and sustainability

Eveborn, David January 2010 (has links)
<p>For many surface waters, phosphorus (P) leaching is a serious problem that should be minimized to prevent eutrophication. In Sweden there is a demand for physical and technical development of high-performance P removal techniques to reduce phosphorus leaching from on-site wastewater treatment systems to the Baltic Sea. However, although these systems are designed to reduce eutrophication there are also other environmental impacts to be considered when implementing them in on-site systems; energy use and global warming potential are two examples. This study has investigated several bed filter materials (reactive media and natural soils) for their total environmental impact (in commercial applications) as well as for the predominating chemical phosphorus removal mechanisms. The use of life cycle assessment revealed that several reactive bed filters are relatively energy-consuming due to the material manufacturing process. Characterization of phosphorus compounds in used reactive media provided evidence for calcium phosphate precipitation as the predominating P removal mechanism in alkaline filter materials. However, in soil treatment systems with noncalcareous soils, batch experiments and extractions suggested that aluminium compounds were important for P removal. According to mass balance calculations that compared accumulated P with the estimated P load in a soil treatment system, the long term P removal capacity was very low; only 6.4 % of the applied phosphorus had been removed during 16 years of operation.</p>

Achieving Next Generation Environmental Impact Assessment Follow-up and Monitoring

Andronak, Brett 17 April 2017 (has links)
Despite growing scrutiny of Environmental Impact Assessment (EIA) in Canada and worldwide, the follow-up and monitoring component remains under practiced, leaving EIA decision-makers and practitioners with little understanding of the accuracy of impact predictions made and the effectiveness of mitigation measures developed during the EIA project-planning phase. The Minister’s Expert Panel further highlighted the importance of enhancing follow-up and monitoring during the recent review of EIA processes in Canada. The research identifies six leading edge practices for next generation EIA follow-up and monitoring: public and Indigenous participation, continuous learning, clear roles and responsibilities, independent oversight, adaptive management and traditional knowledge. Approaches to implement those practices in a Canadian context are explored and supported by guidance that captures the learning potential of EIA follow-up and monitoring. The six practices are intended as a package and are presented with practical guidance for proponents, regulators, consultants and others involved in EIA. / May 2017

Posuzování vlivu na životní prostředí v judikatuře Evropského soudního dvora / Environmental impact assessment of projects in the case law of the Court of Justice of the European Union

Glatzová, Monika January 2013 (has links)
Environmental impact assessment of projects in the case law of the Court of Justice of the European Union Environmental impact assessment (EIA) is a horizontal tool of protection of the environment, based on principles of precaution and prevention and aimed at assessment of plans and programs, or projects. This thesis deals with assessment of projects only. At EU level, the legal basis for EIA of projects is provided for by the EIA Directive (Directive 2011/92/EU) which is expected to be amended in the near future. The thesis provides for an analysis of the EIA case law of the Court of Justice of the EU (CJEU), identifies the main problems encountered by the Member States when implementing the EIA Directive, identifies the key principles established by the CJEU for interpretation of the EIA directive, and in the light of the above it identifies the main issues in the transposition in the Czech law. 1

South African transnational mining companies and environmental impact assessment in the Democratic Republic of Congo

Dechuvi, Kasemire Rosine 02 1900 (has links)
A research report submitted to the Faculty of Science, in partial fulfilment of the requirements for the degree of Master of Science, University of the Witwatersrand, Johannesburg. February 2015. / This study examines the practice of environmental impact assessments (EIAs) by South African mining transnational companies (TNCs) operating some mining projects in the Democratic Republic of Congo (DRC). It analyses whether and how South African mining TNCs carry out EIAs for their mining projects in the DRC, especially whether they follow (1) the DRC EIA policies, (2) the South African EIAs policies (3) international EIA policies, or (4) internal company policies. It also examines what motivates the companies to follow any of the policy path, by assessing whether financial or policy regimes evaluations motivates the TNCs to follow the certain path. Through the case studies of AngloGold Ashanti and Metorex (Pty) Limited, the study demonstrates the complexity involved in making decisions on choosing a policy path to follow which confronts TNCs. The conclusion we draw from this study is that TNCs do not follow a single policy path in carrying out EIAs but integrate a number of policies and standards and the integration of various policies and standards demands highly qualified and well trained staff as well as availability of an enabling scientific and research infrastructure within the host country.

O lugar do social na avaliação de impacto ambiental: regulação pública no Brasil, avanços teóricos e desafios para o planejamento regional / The place of the social in the evaluation of environmental impact: public regulation in Brazil, theoretical advances and challenges for regional planning

Carolino, Ariella Kreitlon 07 June 2016 (has links)
A presente pesquisa tomou por objeto de estudo central a dimensão social (mais conhecida como \'componente antrópico\' ou \'componentes do meio socioeconômico\') consubstanciada na prática e no discurso de avaliação de impacto ambiental. Buscou-se analisar as ausências, lacunas, insuficiências, distorções e omissões ativas no trato dessa dimensão social, procurando compreendê-las como indícios da configuração momentânea das fronteiras do \'social\' na regulação ambiental de projetos no Brasil, enquanto construção histórica atravessada por interesses conflitantes entre os envolvidos nas disputas por hegemonia do campo ambiental, sem perder de vista seu diálogo com outros campos do espaço social, como o político e o econômico. Através dessa chave interpretativa, foi possível retomar as origens e características históricas que conformaram os sentidos dominantes de termos como \'meio ambiente\', \'impacto ambiental\' e \'atingido\' na regulação pública e na atividade de avaliação de impacto, subsumindo da equação os impactos e processos sociais relacionados à implantação de grandes projetos. A pesquisa argumenta, nesse sentido, que ao componente social tem sido atribuído um papel marginal, frágil e bastante delimitado espacial e temporalmente, corroborando com críticas históricas a este instrumento de planejamento. Diagnósticos empobrecidos, avaliações que escamoteiam a complexidade de impactos sociais cumulativos, indiretos e de segunda ordem (cujas marcas são o longo prazo, a fluidez das fronteiras espaciais, a imprevisibilidade, a intangibilidade e a dificuldade de valoração monetária) e medidas mitigadoras e compensatórias insuficientes são ilustrados empiricamente pela pesquisa, tomando o estudo de impacto ambiental de um projeto de anel rodoviário recente, situado no Litoral Norte do estado de São Paulo, como matéria-prima principal de análise. Aliado a uma metodologia investigativa, baseada no levantamento de documentos oficiais do processo licenciatório, a pesquisa procurou identificar os meandros, os mecanismos, as operações e os filtros que recolocam o \'social\' como parte subordinada da avaliação de impacto ambiental, dando pouquíssimo relevo a questões fundamentais, como: fluxos migratórios, crescimento demográfico, demanda adicional sobre infraestrutura e serviços urbanos, transformações da paisagem e novas configurações urbanas, mudança de perfil sociocultural e econômico em nível regional, etc. Em paralelo, após extensa revisão bibliográfica nacional e internacional na área de avaliação de impacto social (que serviu de embasamento teórico-conceitual à pesquisa), procurou-se averiguar em que medida as novas formulações discursivas emergentes, tanto no campo ambiental quanto no subcampo profissional da avaliação de impacto, nos últimos trinta anos, têm encontrado ressonância na prática da avaliação de impacto ambiental de projetos, no país - i.e., como têm sido apropriadas por agentes reguladores e consultores técnicos responsáveis pelos EIAs. Por fim, a pesquisa buscou tecer reflexões sobre as potencialidades e limitações inerentes à avaliação de impacto ambiental como instrumento de planejamento regional, integrado, democrático, fundado em princípios de equidade ambiental e no reconhecimento das demandas de grupos sociais atingidos. / The present study has focused on the social dimension (better known as \'anthropic component\' or \'components of the socioeconomic environment\'), based on the practice and discourse of environmental impact assessment. It sought to analyze the absences, gaps, inadequacies, distortions and omissions that are active in the treatment of this social dimension, seeking to understand them as signs of the momentary configuration of the boundaries of the \'social\' in the environmental regulation of projects in Brazil, as a historical construction crossed by interests Conflict between those involved in environmental hegemony disputes, without losing sight of their dialogue with other fields of social space, such as political and economic. Through this interpretive key, it was possible to return to the origins and historical characteristics that conformed the dominant meanings of terms such as \'environment\', \'environmental impact\' and \'reached\' in public regulation and impact assessment activity, subsuming impacts And social processes related to the implementation of large projects. The research argues, in this sense, that the social component has been assigned a marginal, fragile and quite delimited spatial and temporal role, corroborating historical criticism of this planning instrument. Impoverished diagnostics, assessments that eschew the complexity of cumulative, indirect and second-order social impacts (whose long-term marks, fluidity of spatial boundaries, unpredictability, intangibility and difficulty in monetary valuation) and insufficient mitigating and compensatory measures Are empirically illustrated by the survey, taking the environmental impact study of a recent road ring project, located in the North Coast of the state of São Paulo, as the main raw material for analysis. In addition to an investigative methodology, based on the collection of official documents of the licensing process, the research sought to identify the meanders, mechanisms, operations and filters that replace the \'social\' as a subordinate part of the environmental impact assessment, giving very little emphasis to Such as: migration flows, population growth, additional demand on infrastructure and urban services, landscape transformations and new urban configurations, socio-cultural and economic profile change at the regional level, etc. In parallel, after extensive national and international literature review in the area of social impact assessment (which served as a theoretical-conceptual basis for research), it was sought to determine to what extent new emerging discursive formulations, both in the environmental field and in the professional subfield Of the impact assessment over the last thirty years have found resonance in the practice of assessing the environmental impact of projects in the country - ie as they have been appropriated by regulators and technical consultants responsible for EIAs. Finally, the research sought to reflect on the potentialities and limitations inherent to environmental impact assessment as a regional, integrated, democratic planning tool based on principles of environmental equity and the recognition of the demands of affected social groups.
