This thesis is composed of three essays. In the first essay I identify the effects of imposing a broad range of environmental regulations under different market conditions.. I compare four types of regulatory controls under Perfect Competition, Monopoly, and Cournot Competition: Emission Standards, Design Standards, Concentration Standards, and Output Standards. I rank each of the standards in terms of firm profitability, industry output, abatement costs, and social welfare. I derive sufficient conditions for Design, or Concentration Standards, to dominate Emission Standards. I show how the different forms of regulation can raise industry profits by reducing the degree of inter-firm competition. Further, I show how environmental regulations can enhance competition and yield a "double dividend": higher Social Surplus and less pollution. In the second essay I extend the comparison of standards to an open country. I show how a country's choice of regulatory regime influences the level of environmental protection when governments care about the competitiveness of their industries. I show that the mode of regulation can create a "race to the bottom" if regulators behave strategically. I show that Emission Standards permit the race, as do Emission Charges. Design Standards, on the other hand, avoid the race altogether by breaking the link between environmental stringency and industrial competitiveness. Countries using Design Standards will always regulate emissions. This holds regardless of the environmental stance taken by competitor nations. If countries do not behave strategically, then Emission Standards and Emission Charges always dominate Design Standards. In the third essay I use the concept of home biases in traded goods, or "Border Effects", to rank industries and countries in terms of their openness to trade. I first confirm the presence border effects for individual sectors and individual industries among OECD countries for 1970 to 1985. I also examine whether country-specific border effects are determined by the sectoral composition of a country's production. I find limited evidence to support this. Rather, per capita incomes appear to be the most important factor. The conclusion I draw is that the level of development appears to be the prime factor in explaining the differences in country-specific border effects. What countries produce is of some importance. Therefore, we should see continued, though possibly slow, reductions in home biases as all countries continue to develop. This will partially determine the kind of environmental regulation used as well as their level. / Arts, Faculty of / Vancouver School of Economics / Graduate

Bibliography: leaves 97-100. / This dissertation forms part of a process which began when DANCED initiated the first stages of a project aimed at aiding the Namibian Government in the development of an Integrated Coastal Zone Management _Plan for the coastline of the Erongo Region. DANCED requested the assistance of the MPhil students, from the Department of Environmental and Geographical Science of the University of Cape Town, in the compilation of a baseline report for the region. The first step involved the collection and synthesis of baseline data on all environmental factors (natural and social) pertaining to the Erongo Region. This was followed by individual research dissertations by each member of the class. After review of the Baseline Report, the greater Walvis Bay 'bay area ' was identified as a priority area in terms of coastal zone management of the Erongo Region. The aim of this dissertation is thus to provide an environmental overview of the Walvis Bay ' bay area' that can assist planners and relevant authorities in the effective management the area. Firstly, the importance of the study area as a conservation area is established. It is noted that the Walvis Bay wetland is one of the top five most important wetland areas in Africa. Secondly, there is little co-ordination and communication between the authorities that have jurisdiction over portions of the study area and this has led to ineffective management of the area. Thirdly, the study area is defined and the major human activities operating within the study area are identified and described.

Bibliography: pages 53-57. / This dissertation has four main aims: 1. To assess whether multi-media (particularly interactive video) can be used in illiterate and semi-literate communities as a tool for both increased environmental awareness and increased participation in various stages of the development process. 2. To assess whether interactive video as an approach in itself facilitates empowerment of target communities. 3. To create a visual communication experience which combines the rigours of academic research with the practical application of academic theories in the field. 4. To foster a sensitivity in the "reader" towards access to information.

A research report submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the degree of Master of Science, 2018 / South Africa has implemented regular amendments to the Environmental Impact Assessment (EIA) regulations in an attempt to improve the effectiveness of the process. One way of evaluating effectiveness is to assess the quality of EIA reports submitted for decision-making. This study aimed to assess whether the amendments to the National Environmental Management Act (NEMA), (Act no 107, 1998) EIA regulations in 2014 have contributed to better EIA report quality in South Africa in comparison to the previous EIA system. As such, a sample of 26 EIA reports, 16 under the 2010 EIA regulations and 10 under the 2014 EIA regulations, were reviewed using an adapted version of the Lee and Colley review package. The findings of this research revealed that overall report quality improved under the 2014 EIA regulatory system compared to the 2010 system. Furthermore, an improvement in the 2014 EIA report quality indicates that the decision-making process is more well informed and holistic, which further indicates an improvement in effectiveness of the EIA process. Key amendments to the 2014 EIA regulations that have an influence on EIA report quality include appendix 2 which outlines the objective, scope and content of a scoping report, appendix 3 which outlines the objective, scope and content of an EIA report, appendix 4 which outlines the content of an EMPr, and appendix 6 which outlines the content of a specialist report. It is thus concluded that amendments to the EIA regulations have in fact influenced report quality. These findings differed from those of other studies undertaken on EIA quality under the 2006 EIA system in comparison to the 1997 EIA system. Key words: Environmental Impact Assessment, Effectiveness, Environmental Impact Assessment Report, EIA Report Quality, EIA Regulations, National Environmental Management Act. / XL2019

Research report submitted in accordance for partial requirements for the degree of Masters in Interdisciplinary Global Change Studies in the Faculty of Science at the University of the Witwatersrand, 2018 / The vision for this project is to aid in approaching climate change by providing an improved understanding of environmental concern. There are two missions. First, to develop heuristic models of environmental concern, and to utilize their constructs to assess environmental behaviour and environmental concern in a population. The model is intended to provide a depiction to aid in better understanding environmental concern and may aid in framing and developing intervention strategies to mitigate harmful effects of climate change. Broadly, assessments of environmental concern have been operationalized in two ways, as a unidimensional construct, ranging from high concern to low concern, or as multidimensional constructs demonstrating underlying reasons for environmental concern. Examining two multidimensional assessments reveals limitations of both and gaps between their underlying constructs. A reading of value-orientated theories from environmental ethics literature identifies six constructs for use in a multidimensional assessment of environmental concern. Utilizing equivalent constructs to the previous multidimensional assessments and expanding “nature” and natural entities into three separate categories results in six constructs intended to fill the gaps of the previous multidimensional assessments and may addresses some of their limitations. This reading also provides a theoretical foundation for designing items to relate to the six constructs. A theory map is presented which demonstrates constructs relating to an expanded narrative for use in multidimensional assessments. Climate change is a complex and often poorly understood phenomenon. Furthermore, it is clear that human behaviours are the underlying causes of climate change. Cross-disciplinary research and integration of several disciplines and fields of inquiry are necessary for developing sound approaches to climate change. Experimental philosophy and empirical ethics are discussed as guiding methodologies for this project. Meta-ethical fallacies and two considerations from the philosophy of science aid in contextualizing this research and provide epistemological limits for deriving ethical conclusions from facts about the world. A survey consisting of 11 sociodemographic items, the revised NEP scale’s 15 items, an existing 17 item environmental behaviour scale, and six 10 item original scales relating to six constructs based on value-orientated theories from environmental ethics and presented in the heuristic models, was drafted. An electronic version was designed and emailed to firstyear Life Science and Economics students. The environmental behaviour scale and the revised NEP scale are significant and correlate moderately positively, corroborating the hypothesis, that there is a relationship between environmental behaviour and environmental concern. While three of the six original scales (egocentrism, sociocentrism, and sentiocentrism) were unreliable, did not have many significant relationships with other variables, and require further development, the other three (nihilism, biocentrism, and ecocentrism) succeeded in corroborating the hypothesis, that there are underlying dimensions of environmental concern, and that they are significantly related to environmental behaviour. The project’s implications and recommendations discusses different intervention strategies in response to climate change as well as environmental communications and education, and how the heuristic models may aid in these topic’s endeavours. The project concludes by identifying a lack of environmental concern in two South African President’s State Of the Nation Addresses and stresses the need to improve environmental concern and increase the frequencies of people engaging in environmental behaviours. Key words: nature; natural entities; environment; environmental concern; environmental behaviour; value; environmental communication; environmental education; nihilism; anthropocentrism; egocentrism; sociocentrism; sentiocentrism; biocentrism; ecocentrism; experimental philosophy; empirical ethics; quantitative research. / XL2019

Global warming is an impending crisis that poses severe ecological and economic consequences if left unaddressed. The primary cause of this crisis is the emission of carbon dioxide (CO2), making it crucial to identify and implement effective emission-mitigating measures. One potential measure is renewable energy sources, such as photovoltaic (PV) systems. This study aims to estimate the emission mitigation effect of PV systems in Sweden, a country of interest due to its already high share of green energy production. This poses a challenge in predicting the emission mitigation effect of PV adoption, as it relies on replacing fossil-based power production. By using a municipality-level panel data set spanning the years 2016-2020 coupled with a multiple regression approach, a statistically insignificant relationship is found between CO2 emissions per capita and installed PV effect per capita in Sweden. This counter-intuitive and unfortunate result emphasises the difficulty of designing effective environmental policy.

Municipal recycling is driven by a variety of factors. Yet how these factors change over time is not well understood. I analyze a suite of contextual and program variable in multiple time periods, spanning 16 years, in the Commonwealth of Massachusetts. Based on the models run, I reach the surprising conclusion that most program variables have an insignificant effect on recycling rates. These findings can inform municipal officials and waste managers as they seek new ways to increase municipal recycling participation.
