There is no doubt that the assessment of social impacts is as important, in some cases even more important, than the assessment of biophysical and economic impacts of development projects. Nonetheless, social impact assessment (SIA) has remained an "orphan" in the broader environmental impact assessment (EIA) context, both internationally and in South Africa, and is often neglected or treated as a less important aspect of an EIA. It was the aim of this study to measure perceptions of relative neglect of SIA in South Africa against the theory and practice of SIA as reflected in the literature. The basic hypothesis was that, whereas the theory and practice of SIA has reached a sophisticated level in the developed world, the practice of SIA in South Africa is not yet on a sound footing and that it does not receive the professional attention it deserves in a country beset by enormous social challenges. Thus the research problem was whether SIA is practiced at a satisfactory level of proficiency in South Africa. Social aspects of impact assessment in the North West Province of South Africa were investigated, with the aim to identify shortcomings and their possible causes and to make recommendations for improvement. The article format was used, and the main section of the study comprises two articles. The first article, a theoretical perspective based on a literature study, is a critical evaluation of SIA as part of the EIA process in South Africa against the background of international guidelines and best practices. The article includes sections on the historical background of the development of SIA in South Africa, the legal status and requirements of SIA in the country, and a critical evaluation of SIA regulation in South Africa. It was found that the persistent problems of SIA practice, experienced in other parts of the world, are also evident in South Africa. Apart from institutional, financial and professional constraints, there are also serious problems associated with approach and methods. The second article is an evaluation of and recommendations for the improvement of the practice of SIA in the North West Province. An empirical study of 26 EIAs, performed in the province between 1999 and 2002, was done. It was established that in terms of social baseline data, the identification of significant social impacts, specialist studies, public participation, recommended mitigation measures, and the attention paid to social impacts in records of decision (RODS) SIA practice in the North West Province is far from satisfactory. Apathy towards social impacts is associated with a general lack of SIA expertise. The following recommendations are made in the study to improve the level of SIA practice: a system of mandatory registration of SIA practitioners should be introduced; specialized SIA training programmes for SIA practitioners and officials should be developed and accredited; SIA specialists should be used to assess significant social impacts identified in EIAs; a policy framework and code of ethics for SIA practice should be developed; methodological guidelines for SIA should be supplied in or as a supplement to the new EIA guidelines; and the public participation process should be redesigned. / Thesis (M.

Environmental Impact Assessment (EIA) is recognised worldwide as a tool for identifying the potential adverse effects of a proposed development on the environment. Very little attention has been given to determining the actual environmental effects resulting from a development. The need for EIA follow–up (i.e. monitoring, auditing, evaluation, management and communication) was identified and would form the building blocks within the EIA process. Follow–up provides information about the consequences of an activity and presents opportunities to implement adequate mitigation measures. EIA follow–up is not developed to its full potential even though the need for it is acknowledged and supported in legislation, scientific journals and scientific books. EIA follow–up necessitates feedback in the EIA process to ensure lessons learnt and outcomes from past experiences can be applied in future actions. Follow–up is only a legal requirement if conditions are specified in the environmental authorisation (EA). Of particular concern to follow–up is the accuracy of prediction and secondly, the level of compliance to conditions set out in the authorization and management plans. This study will focus primarily on critically analysing predictions and compliance from the construction phase of a high profile mega shopping mall project, namely the Mooi River Mall (MRM), with an analysis to gauge the actual effect and contribution of the EIA process to decision making and implementation practices. Multiple data sources were used to determine the accuracy of predictions and legal compliance level of the Mooi River Mall. The Mooi River Mall's accuracy of predictions (66%) and legal compliance (83%) suggest that some of the impacts were unavoidable; that mitigation measures were either not implemented or identified or that EIA follow–up served its purpose in the form of implementing effective auditing programmes to monitor legal compliance. / Thesis (M.Sc (Environmental Science))--North-West University, Potchefstroom Campus, 2011.

Building envelopes are elements with a long lifetime, which provide a barrier between internal and external space and contribute to the internal environmental conditions provision. Their complex role ensures a large impact on the environmental and energy performance of a building and the occupant perception of a space. This study looks at the use of novel materials and processes to help reduce the environmental impact of buildings by improving facade and transparent roof design. There are three main strands to the work. First, novel building components, ETFE foil cushions were examined. Physical testing has shown that ETFE foil cushions compare favourably to double glazing in terms of thermal and daylighting performance which was also noted as one of the most likeable feature by occupants. Environmental impact analysis has indicated that ETFE foils can reduce the environmental impact of a building through reduced environmental burden of both the construction and operation of the building. Secondly, a cradle-to-gate Life Cycle Analysis (LCA) was carried out for float glass, which considered the environmental impacts of glass manufacture. The embodied energy was calculated to be 13.4 ± 0.5 GJ per tonne while the total number of eco-points 243 ± 11 per tonne. It is shown that float glass is comparable to the use of steel, and highly preferable to the use of aluminium as a cladding panel. Finally, a concept design tool (FACADE) was developed by defining a large number of office facade models and employing dynamic thermal, daylighting and environmental impact modelling to create a database which can be accessed through a user friendly interface application. A parametric analysis has indicated that using natural ventilation where possible can reduce the environmental impact of offices by up to 16%. Improving the standard of the facade and reducing the internal heat loads from lighting and equipment can reduce environmental impact up to 22%. This study makes a significant contribution to understanding the environmental impact of building envelope individual and integrated components.

The conversion of wave energy into electrical energy has the potential to become a clean and sustainable form of renewable energy conversion. However, like all forms of energy conversion it will inevitably have an impact on the marine environment, although not in the form of emissions of hazardous substances (gases, oils or chemicals associated with anticorrosion). Possible environmental issues associated with wave energy conversion include electromagnetic fields, alteration of sedimentation and hydrologic regimes and underwater radiated noise. Underwater noise has the potential to propagate over long distances and thus have the potential to disturb marine organisms far away from the noise source. There is great variation in the ability to perceive sound between marine organisms, one sound that is clearly audible to one species can be completely inaudible to another. Thus, to be able to determine potential environmental impact from WECs associated with underwater noise, the noise radiated from the WECs must be known. This thesis presents results from studies on the underwater radiated noise from four different full-scale WECs in the Lysekil Wave Power Project. Hydrophones were used to measure the underwater radiated noise from operating point absorbing linear WECs. The main purpose was to study the radiated noise from the operating WECs with emphasis on characteristics such as spectrum levels, Sound Pressure Level (SPL), noise duration and repetition rate. This to be able to determine the origin of the noise and if possible, implement design changes to minimize radiated noise. The results identified two main operational noises (transients with the bulk of the energy in frequencies &lt;1 kHz). The SPL of the radiated noise fluctuated significantly, depending on wave height. Broadband SPLrms of the measurements ranged between ~110 dB and ~140 dB re 1 µPa and SPLpeak of specific noises ranges between ~140 and ~180 dB re µPa. Audibility was estimated range from 1km to 15 km depending critically on species and on assumptions of propagation loss. The noise is not expected to have any negative effects on behaviour or mask any signals, unless in the vicinity (&lt;150m) of the WECs in significant wave heights. No physical damage, even in close vicinity are expected on either fish or marine mammals. Having the aim to have as little impact on the environment a possible, these studies are important. This way precautions can be implemented early in the technical development of this kind of renewable energy converters. The benefits from the WECs the Lysekil wave power project are believed to outweigh possible environmental impacts due to underwater radiated noise. / <p>Vid avhandlingens tryckläggning upptäcktes inte att tidpunkt för disputation var fel.</p>

The residential sector is recognized as a major energy consumer and thus a significant contributor to climate change. Rather than focus only on current energy consumption and the associated emissions, there is a need to broaden sustainability research to include full life cycle contributions and impacts. This thesis looks at houses from the perspective of the Ecological Footprint (EF), a well-known sustainability indicator. The research objective is to integrate EF and Life Cycle Analysis (LCA) measures to provide an enhanced tool to measure the sustainability implications of residential energy retrofit decisions. Exemplifying single-detached houses of the early 20th century, the century-old REEP House (downtown Kitchener, Canada), together with its high performance energy retrofits, is examined in detail. This research combines material, energy and carbon emission studies. Its scope covers the life cycle of the house, including the direct and indirect consumption of material and energy, and concomitant carbon emissions during its stages of material extraction, transportation, construction, operation, and demolition. The results show that the REEP House had a significant embodied impact on the environment when it was built and high operating energy and EF requirements because of the low levels of insulation. Even though the renovations to improve energy efficiency by 80% introduce additional embodied environmental impacts, they are environmentally sound activities because the environmental payback period is less than two years.

The main purpose of this dissertation is to develop a process to improve actual policy-making procedures in terms of aviation environmental effects. This research work expands current practices with physics based publicly available models. The process herein proposed provides information regarding the interdependencies between the environmental effects of aircraft. These interdependencies are also tied to the actual physical parameters of the aircraft and the engine, making it more intuitive for decision-makers to understand the impacts to the vehicle due to different policy scenarios. These scenarios involve the use of fleet analysis tools in which the existing aircraft are used to predict the environmental effects of imposing new stringency levels. The aircraft used are reduced to a series of coefficients that represent their performance, in terms of flight characteristics, fuel burn, noise, and emissions. These coefficients are then utilized to model flight operations and calculate what the environmental impacts of those aircraft are. If a particular aircraft does not meet the stringency to be analyzed, a technology response is applied to it, in order to meet that stringency. Depending on the level of reduction needed, this technology response can have an effect on the fuel burn characteristic of the aircraft. The proposed alternative is to create a fleet of replacement aircraft to the current fleet that does not meet stringency. These replacement aircraft represent the achievable physical limits for state of the art systems. In addition, the replacement aircraft show the linkage between environmental effects and fundamental aircraft and engine characteristics, something that has been neglected in previous policy making procedures. Another aspect that has been ignored is the creation of the coefficients used for the fleet analyses. In current literature, a defined process for the creation of those coefficients does not exist, but this research work develops a process to do so and demonstrates that the characteristics of the aircraft can be propagated to the coefficients and to the fleet analysis tools.

This thesis investigates the participation of Maori (New Zealand�s indigenous people) in the impact assessment process. Traditionally, Maori have had limited involvement in the management of New Zealand�s environment. One possible solution to this could be through the adoption of a collaborative management framework. Unfortunately, there is limited information and research on tools that could facilitate collaborative management between iwi and applicants for resource consent (including, developers, planning consultants and local authorities). Therefore, this research attempts to fill in a gap in current literature and to investigate the potential of the cultural impact assessment as a tool for collaborative management. Despite some criticisms of collaborative management, there are examples where this form of communicative planning has resulted in a very positive outcome for indigenous groups. Therefore, the specific aim of this research is to analyse the extent to which cultural impact assessments can be used as a tool to promote collaborative management between iwi and applicants. In achieving the research objectives of the thesis, the theoretical background of collaborative management and impact assessment theories are explored. In addition, democracy and participation theories are also investigated. In particular, in the discussion of these theories emphasis is placed on the potential involvement of indigenous peoples. The thesis argues that the application of collaborative management via the use of cultural impact assessments may potentially increase Maori involvement in planning. Analysis of collaborative management and impact assessment theories is supported by empirical research. This includes; 1) an exploration of the New Zealand setting for the two theories, 2) a content analysis of cultural impact assessments from eight different iwi authority in New Zealand, and 3) a case study analysis of two iwi organizations that have an established system for undertaking cultural impact assessments (Kai Tahu ki Otago and the Wellington Tenths Trust). The research finds that cultural impact assessments are very similar to other impact assessment reports. However, they should be viewed as evolving documents, as there are some areas of the assessment process that need to be improved upon. The research concludes by suggesting that cultural impact assessments do have the potential to be a tool for collaborative management between iwi and applicants. Further research and education in relation to the content, value and process of cultural impact assessments is required. It is also argued that increased resourcing, training and legislative requirements are needed to further increase Maori participation in planning.
