Experience of EIA follow up in Lesotho.

Tsehlo, Matseliso. January 2003 (has links)
Environmental Impact Assessment (El A) is a process that is widely practised as it assists in decision-making and also helps to overcome the environmental problems that could result from development activities. However, the focus is still on EIA as a process and less on EIA follow-up. EIA follow-up is taken to mean the activities, such as monitoring and auditing, that are carried out after the Record of Decision has been made, although the importance of establishing EIA follow-up early in the project cycle is emphasised in this thesis. In most countries, EIA follow-up is not legislated and whilst it is generally recognized as important it is not widely practised. This thesis is aimed at assessing the status of EIA follow-up in Lesotho. Nine development projects were selected and their reports; Environmental Impact Assessment Reports (EIRs), Environmental Management Plans (EMPs) and auditing reports were analysed to determine if there was provision for EIA follow-up. Four criteria were utilised in the analysis. These were: the impacts that were predicted and mitigation measures proposed, the provision made for EIA follow-up before the implementation of the project, the impacts that were experienced and the mitigation measures that were put in place and the EIA follow-up process that was undertaken, and the people responsible for it. All projects had undergone an EIA process, except for one which did not have an EIR prepared, viz. C& Y garment factory at the Thetsane industrial site. Of the remainder, four projects contained provision for EIA follow-up, although in most case studies follow-up focused on the construction phase and little was stated about the implementation of follow-up. Generally, an environmental officer was appointed to monitor the impacts that were experienced and to ensure compliance with the EMP. However, in the Butha-Buthe industrial estate case study, the EIA follow-up process was detailed and specific, even giving the frequency with which EIA follow-up should be undertaken, by whom and how it should be done. This is most likely because it is the most recent industrial estate to be developed and that lessons were learned from previous industrial development sites discussed as case studies in this thesis, where problems were encountered due to lack of EIA follow-up. Apart from the assessment of these reports, questionnaires were also administered to nine environmental consultants practising in Lesotho. Monitoring and auditing were identified as EIA follow-up by the majority of consultants (7 or 78%). Only one person identified it as including public participation, while the other person (11 %) identified it as monitoring, which incorporates EMPs and Environmental Management Systems (EMSs). It was interesting to note that only one person included public participation as part of EIA follow-up, in contrast to the general understanding of EIA follow-up internationally, that the public have a role to play in follow-up activities. One person (1 or 11 %) pointed out that EIA follow-up should start at the planning or design stage, while the majority (89%) stated that it should start after the completion of the EIA process and the Record of Decision, the latter group failing to recognise the importance of collecting baseline data early in the EIA process. Of all the projects, only the Lesotho Highlands Water Project (LHWP) was observed to implement EIA follow-up, such as monitoring and auditing, on a regular basis. An assessment was also undertaken of the environmental legislation in Lesotho and the provision that it makes for EIA follow-up. Sections 31 and 32 of Part V of the Act specifically give provision for EIA follow-up. It is stated that in order to prevent environmental degradation, environmental monitoring and environmental auditing should be undertaken. Moreover, the Lesotho EIA guidelines (1997) do give guidance and procedures on how EIA follow-up should be undertaken. However, it was found that currently, the Environment Act, 2001 is not operational and that EIA follow-up like the EIA process is undertaken on a voluntary basis. It was therefore recommended that at present, the self-regulatory approach to EIA follow-up is the most suitable one for Lesotho. Recommendations were made to strengthen this approach until such time as legislation is in place or an environmentally aware public can participate in EIA follow-up. Several problems were identified that were hampering the practice of EIA follow-up in Lesotho. These included: the un-operational Environment Act, an environmentally unaware public, few environmentalists and lack of sensitive and dedicated government ministries. / Thesis (M.Sc.)-University of Natal, Durban, 2003.

The integration of the social environment into the development planning process : a case study of petrol filling stations (PFS)

Gouden, Krishni. January 2010 (has links)
The aim of this dissertation is to examine the integration of social issues into the Development Planning Process through environmental assessment procedures. A Case Study of Petrol Filling Stations (PFS) was examined in order to assess the level of integration of the social environment into the development planning process. It is often the case that developments, especially large developments, are conceptualized at a scale that marginalises the needs of local communities. The indirect cost and benefits of these developments on the community is not adequately researched prior to the implementation of these developments. Local concerns from the social environment are often marginalized in the decision making process. The literature in the study indicates that public involvement is often seen as anti-development, reflecting self-interest and being typical of the NIMBY (Not in my backyard) Syndrome. This dissertation comprises two main parts. The first part provides the theory and methodology employed by the researcher to gather data to explore the topic. International and national literature is analysed in relation to the Development Planning Process, Environmental Impact Assessments (EIA) and its evolution, Public Participation, The NIMBY Syndrome, Social Impact Assessments (SIA) and relevant case studies are explored. The second part of this research analyses in detail the case study in relation to the development planning process and the EIA process. The intention of the analysis of the case studies was to establish at exactly what point the social environment is included in the development planning process and EIA process. The intention was to further establish if the process and its practice is adequate in ensuring the assessment and inclusion of the social environment into the decision making process. The second part of this research also analyses the interviews that were undertaken in order to assess how practitioners consider and include the social environment into the decision making process. The research confirms that in this particular instance the social environment was not adequately included early enough in the decision making process. Often social concerns are considered by developers to be a mechanism to delay development and are viewed as a “stumbling block” to development. However, the recognition of social issues and good public participation have been recognized as an important factor in ensuring quick decision-making and successful implementation of projects. Social screening is critical at the outset, prior to a development application being lodged with the relevant approval authority. Developers have recognized the importance of SIA and thorough public involvement in projects. Social screening can be used as a tool outside of, or prior to, the formal Development Planning and EIA application processes. / Thesis (M.Sc.)-University of KwaZulu-Natal, Westville, 2010.

An assessment of Environmental Impact Assessment (EIA) procedures and challenges faced by environmental officers in EIA implementation in Rwanda.

Munyazikwiye, Faustin. January 2011 (has links)
Environmental Impact Assessment (EIA) is one of the most used tools for environmental management since its introduction in 1970s in the United States of America. Being a systematic process that examines the environmental consequences of development actions in advance, it is perceived as one of the tools which can help different nations to achieve sustainable development because of its capabilities to provide necessary information for decision-makers in order to balance economical, social and ecological paradigms of sustainable development in development projects. This research aims to assess the practice of the EIA processes in Rwanda and specifically seeks to identify the major challenges faced by environmental officers in this process. Given the nature of this research, policy review and desktop research methods have been used to study the current EIA procedures in Rwanda while a quantitative survey method was used to collect data and assess the practices of EIA process as well as the challenges faced by environmental officers in Rwanda. All environmental officers (8) who were dealing with EIA in Rwanda before the transfer of the EIA department to the Rwanda Development Board (RDB) and all consultant companies which have been approved and which have at least done an EIA study in Rwanda (19) were targeted and received questionnaires via emails. All the environmental officers and 12 (63%) of the consultants responded to the questionnaire. The data was captured in the Software Package for Social Sciences (SPSS) template after being coded and has been analysed thematically. The policy review reveals that the current procedures are being developed given that the EIA process started in 2005. Like many developing countries, implementation remains a key challenge. Institutional arrangements remain to be finalised. In terms of the survey findings, even if EIA officers are more experienced than EIA consultants both have some skill gaps including using Geographical Information System (GIS) and remote sensing, understanding project management and customer care skills. Additionally, they receive very little training and capacity-building opportunities, although they desire these. The main challenges identified related to insufficient baseline data, funding, shortage of staff, lack of adequate resources, instilling environmental awareness among developers (developers perceive EIA as a barrier) and Strategic Environmental Assessment (SEA) which is not conducted. / Thesis (M.Sc.)-University of KwaZulu-Natal, Westville, 2011.

Modeling the biodynamical response of the human thorax with body armor from a bullet impact.

Lobuono, John A. 03 1900 (has links)
The objective of this study is to develop a finite element model of the human thorax with a protective body armor system so that the model can adequately determine the thorax's biodynamical response from a projectile impact. The finite element model of the human thorax consists of the thoracic skeleton, heart, lungs, major arteries, major veins, trachea, and bronchi. The finite element model of the human thorax is validated by comparing the model's results to experimental data obtained from cadavers wearing a protective body armor system undergoing a projectile impact. When the model is deemed valid, a parametric study is performed to determine the components of the model that have the greatest effect on its biodynamical response to a projectile impact.

Assessing the effect of EIA : the influence of environmental effects information on resource consent decision-making in New Zealand

Schijf, Bobbi, n/a January 2006 (has links)
Environmental impact assessment (EIA) was introduced to inform decision-makers of the potential environmental effects of the decision before them. It has been adopted worldwide and functions as one of the primary instruments for taking account of environmental consequences in project approval decision-making. To date, there has been very little systematic investigation that explores whether the decision-makers for whom the EIA information is produced actually use it, although there are indications that EIA information is not always effective in influencing decisions. This thesis examines how, and indeed if, environmental effects information influences the decision-making processes for which it is produced, and which factors determine the use of this information. Three main areas of concern are identified and investigated: the responses of individual decision-makers to environmental effects information; the characteristics of the effects information that influence these responses; and the processes by which the effects information is dealt with. At the core of the methodology employed for this research is the development of an exploratory model of EIA-based decision-making. This model builds on the insights into decision processes from a variety of disciplines, including psychology and planning. To test the utility of the model, it is evaluated against the New Zealand system of resource consent approval decision-making under the Resource Management Act, by means of case studies. Through interviews, direct observation, and analysis of written documents the decision processes in these cases are analysed. These techniques have been augmented by psychosocial methods that allow further probing into the decision processes that takes place in a decision-maker�s head. The research results show that the effort that is spent on the preparation of EIA reports and the improvement of EIA processes is not wasted. The EIA information clearly influences the decision processes for which it is intended but it is not influencing decisions optimally. EIA information often competes with information on environmental effects from other sources that is of higher quality, more credible, or better tailored to the decision-makers� information needs. A number of ways in which the use of EIA information could be enhanced is explored in this thesis. Foremost, the improvement of the effectiveness of EIA requires a wider adoption of a decision-making perspective on EIA, and a broader recognition of the information needs of the different decision processes for which EIA is prepared.

Integrated environmental assessment of industrial products

Sun, Mingbo, Mechanical & Manufacturing Engineering, Faculty of Engineering, UNSW January 2004 (has links)
Life Cycle Assessment (LCA) has been successfully used as an environmental assessment tool for the development of ecologically sustainable products. The application of LCA in the early design stage has been constrained by the requirement of large amounts of data and time for carrying out the assessment. In addition, the complexity of LCA causes further difficulties for product developers. In order to integrate the environmental assessment into the process of product development, this research proposes an integrated decision model for sustainable product development and a simplified LCA approach for the application in the early stage of product design. The main advantage of the proposed model is that it incorporates the environmental aspects of product development into the existing product development framework. It enables designers to strike a balance between the product???s environmental performance and other traditional design objectives. The simplified LCA approach is based on the concept and application of Environmental Impact Drivers. Material-based environmental impacts and Energy-based environmental impacts are used to predict the total environmental impact of a product. Two sets of impact drivers were developed accordingly. The Material-based Impact Drivers were identified by classifying materials into 16 groups according to the nature of the materials and their environmental performance. Energy-based Impact Drivers were developed for various energy sources in major industrial regions. Product LCA cases were used to verify the proposed methods. The results computed by the application of the impact drivers were compared with the results of full LCA studies. It is concluded that with the proposed approach, the product???s environmental performance can be assessed in a very short time and with very basic data input requirements and acceptable accuracy.
