Keatimilwe, Kagiso P. « Consequences of modernisation in Botswana : lessons and alternatives for the livestock sector ». Thesis, University of British Columbia, 1990. http://hdl.handle.net/2429/30010.
Texte intégralRésumé :
The purpose of this thesis is to analyse the effects of post-independence modernisation policies within the cattle sector in Botswana and to suggest alternative ways of dealing with the challenge of development.
The study pursues four research objectives which are:
1. to examine the environmental effects of cattle production by discussing the impacts of policies on disease control as well as changes in rangeland condition;
2. to discuss the social impacts of the modernisation approach to development by examining data on the distribution of cattle, the financial returns that accrue to owners, and the level of subsidies which the sector receives from the government;
3. to determine the degree of vulnerability of the Botswana cattle sector to decisions made outside the country by investigating the influence of the EEC and certain environmental groups on the beef industry.
4. to suggest a set of principles aimed at making development more ecologically sensitive, more beneficial to most people, and more self-reliant in terms of economic and political decisions.
Modernisation theory according to Hirschman and Rostow contends that
inter-dependence with capitalist economies is a prerequisite for development
(primarily defined as economic growth and not addressing environmental issues);
that the accumulation of wealth will lead to the reduction of poverty; and that
all countries can benefit from the development process. By contrast, Dependency theory according to authors including Prebisch, Frank, Amin, and Sunkel has argued that inter-dependence with capitalist economies retards development; that the national accumulation of wealth does not lead to improved living conditions for much of the population; and that there is little prospect for economic growth in the peripheral countries.
The analysis of policies and measures adopted by the Botswana government involving land reform, disease control, pricing and marketing policies and the use of subsidies reveals that economic growth and access to markets have been attained at the expense of both environmental quality and equity. Future policy for the livestock sector cannot ignore criticism of these impacts without jeopardising the beef trade which has largely been determined by the EEC. This European Community influence raises questions about the extent to which Botswana is in control of her development policy.
Drawing largely from the work of Gardner, the thesis addresses the above concerns by suggesting a set of policy guidelines which identify both the ends and means of decision-making. This framework recognises that the goals of development must include ecological sustainability and economic and political self-reliance in addition to material benefits. Although it recognises the magnitude of the development problems, the thesis concludes by suggesting specific issues which should be investigated to improve living conditions in the country.Applied Science, Faculty of

Increasingly, the environmental impact of animal agriculture is being recognised. In the past, climate criticism was largely reserved for the fossil fuel sector, or even the transport and aviation sectors. However, now it is being realised that the agricultural sector is also a major contributor to climate change, particularly in terms of livestock production. Despite this, little attention has been paid, either in academic writing or in policy making, to improving the climate impacts of the livestock sector. This thesis begins to address this gap. Using a novel critical frame analysis approach, it seeks to provide a broad macro-level analysis of various legal regimes on the international and European level that affect emissions from cattle (and where relevant, livestock more broadly). On the basis of this critical frame analysis, tensions, synergies and common themes for livestock emissions mitigation across these regimes can be identified and investigated. It is hoped that this can help to strengthen productive synergies and to reduce damaging tensions while promoting fairer and more effective emissions mitigation for the sector. Most importantly, the thesis highlights affluence as the ‘forgotten’ problem in reducing cattle emissions. The importance of this key insight in terms of tackling future livestock emissions trajectories is significant, particularly in relation to the climate justice dimension of climate mitigation.

Resumo: Um grande desafio na suinocultura é a definição de um modelo de edificação capaz de proporcionar melhor conforto térmico para os animais. As maiores perdas na produção ocorrem em virtude dos dias muito quentes e das grandes variações térmicas, que são características do clima tropical. Uma alternativa para minimizar estas perdas é a utilização de sistemas diversos de climatização. No entanto, estes equipamentos apresentam custos de implantação, funcionamento e manutenção variáveis que podem interferir na lucratividade do empreendimento. A utilização de um sistema de controle, por exemplo, pode reduzir os custos de funcionamento dos equipamentos. Este trabalho objetivou avaliar a eficiência de diferentes instalações suinícolas, considerando os aspectos do desempenho dos animais, do conforto térmico e da utilização de energia elétrica. Foram comparadas quatro salas de criação de suínos nas fases de crescimento e terminação em uma granja comercial. As salas estudadas são diferentes sob os pontos de vista de construção e climatização (idade dos equipamentos, número de ventiladores, forma de controle da climatização). Os parâmetros utilizados para a comparação entre as edificações foram o desempenho dos animais, condição sanitária do plantel, variáveis climáticas (temperatura e umidade), entalpia e índice de conforto térmico (ITU), variáveis elétricas (consumo, demanda e fator de potência) e índices de eficiência energética dos tratamentos. A utilização de dois ventiladores novos e sistema de nebulização, ambos com acionamento automático, foi capaz de proporcionar melhor conforto térmico aos animais, embora este resultado não tenha sido suficiente para agregar maior produção. Os ventiladores mais novos consumiram menor quantidade de energia elétrica que os antigos e apresentaram melhor fator de potência O tratamento que contou com sistema de nebulização e um ventilador, acionados manualmente, que forneceu a pior condição em termos de conforto térmico, porém apresentou as melhores condições de consumo específico (kg produzido/ kWh consumido). De acordo com a análise dos índices de eficiência energética (fator de carga), os ventiladores com acionamento automático foram melhores utilizados ao longo do tempo. Assim, concluiu-se que a utilização de controle automático de equipamentos de climatização foi capaz de melhorar as condições ambientais e da utilização de energia elétrica
Abstract: A great challenge in the swine production is the definition of a construction model capable of bringing a better thermal comfort to the animals. The greatest losses on production occur due very hot days and great thermal variation, which are the chief characteristics of the tropical weather. An alternative to minimize these losses is the use of diverse climate systems. Nevertheless, these equipment present variable implementation, functioning and maintenance costs that may interfere in the business lucrativity. The use of a control system, for instance, may reduce the equipment functioning costs. This work's main goal is the evaluation on performance of two different swine buildings, considering the animal performance, thermal comfort and electric energy consumption. Four rooms placed on two different swine structures were compared. It all happened on growing and finishing phases, in a commercial pigsty. These rooms are different under building and acclimatization systems (equipment¿s age, numbers of fans and climate control). The parameters used for the comparison between the buildings were the animal performance, group sanitary condition, climate variables (temperature and humidity), enthalpy, thermal comfort index (THI), electric energy variables (electric energy consumption, power factor, demand) and energetic efficiency. The use of two new fans and evaporative cooling system, both with automatic startup, was able to bring a better thermal comfort to the animals, however this result was not enough for bringing higher production. The newer fans consume less electric energy than the older fans and showed the best power factor. The use of an evaporative cooling and only one fan, without automatic control, was able to bring the worst thermal comfort, the worst utilization electrical energy index and showed the best specific consumption. Therefore, we may conclude that the use of an automatic control system to the climate equipment is capable of improving the environmental conditions and the use of electric energy

Thesis (PhD)--Stellenbosch University, 2013.ENGLISH ABSTRACT: The wildlife industry in Namibia continues to grow as the production and consumption of game meat increases. However, the health risks posed by the trade in wildlife and related by-products to livestock and humans have not been fully assessed. The main objective of this study was to investigate the potential health risks related to the increased consumption of game meat and relevant by-products by assessing the quality of game meat, as well as determine the role of game meat species in the transmission of zoonoses. The microbiological quality and safety of export game meat was assessed. No differences in the aerobic plate count (APC) were observed between the years (2009 and 2010), but the mean Enterobacteriaceae count was 1.33±0.69log10 cfu/cm2 compared to 2.93±1.50log10 cfu/cm2 between the years. Insignificant heterotrophic plate count (HPC) levels were detected in 9/23 field water samples, while faecal bacteria (coliforms, Clostridium perfringens and enterococci) were not isolated in all samples. Seven serogroups, with the exception of O26, were detected in exotic species. A white tailed deer sample had a serotype belonging to O45 which confirmed positive for stx1 gene. In springbok, 5/15 pools of faecal samples tested positive for the intimin gene. No Salmonella spp were isolated, and all E. coli isolates from the meat samples were negative for STEC virulence genes (i.e. stx1, stx2, eae and hlyA). A linear regression analysis was conducted on selected variables to identify the main predictors and their interactions affecting pH of meat 4 hours post-slaughter. In an increasing order of magnitude during winter time, the pH reached at 16-36hr post slaughter in springbok heart, liver, spleen, kidney and lungs was significantly higher than pH 6.0, while no significant differences were observed from the regulatory reference (pH 6.0) in the heart. There was a positive association between the pH of game meat 4hr post-slaughter, and liver congestion. The pH of game meat 4hr post slaughter, increased by 0.11 units per mL increase in liver congestion, and decreased by 0.04 units per minute increase in the shooting to bleeding interval, irrespective of the species. Worm eggs of strongylids, Strongyloides papillosus, Toxocara spp, Trichuris spp and coccidia were found in variable numbers in both springbok and gemsbok faeces, indicating a potential risk of transmission to other species in the ecosystem. On examination of carcasses, a novel parasite, Skjabinodera kuelzii, was identified and noted to be associated with inguinal fascia and renal fat, but the public health significance remains unclear. Nevertheless, S. kuelzii should be considered as of potential significance during routine game meat inspection. A total of 12 310 springbok were harvested from 26 commercial farms over a period of two years. Tissue samples (i.e. 60 livers, 41 kidneys and 52 hindquarter muscles) were collected from randomly selected healthy animals. The mean values (i.e. above the detection limit) of cadmium (Cd) and lead (Pb) were 0.10±0.05mg/kg and 1.04±0.21mg/kg in the liver, respectively; and 0.33±0.22mg/kg and 0.905±0.51mg/kg in the kidney of springbok, respectively. The levels of cadmium and lead in the hindquarter muscles were below the detection limit. Serum samples (n=1692) collected from sheep, goats and cattle from four presumably at-risk farms, and 900 springbok (Antidorcas marsupialis) serum samples collected from 29 mixed farming units, were screened for Brucella antibodies by using the Rose-Bengal test (RBT). Positive cases were confirmed by complement fixation test (CFT). To assess the prevalence of human brucellosis, 137 abattoir employees were tested for Brucella antibodies using the standard tube agglutination test (STAT), and the enzyme linked immunosorbent assay (ELISA). Cattle and sheep from all four farms were negative by RBT and CFT, but two of the four farms carried 26/42 and 12/285 seropositive goats, respectively. Post mortem examination of seropositive goats revealed no gross pathological lesions. Culture for brucellae from organs of seropositive animals was negative. None of the wildlife sera tested positive by either RBT or CFT. Occurrence of confirmed brucellosis in humans was linked to the consumption of unpasteurized goat milk, home-made goat cheese and coffee with raw milk and prior contact with goats. All abattoir employees (n=137) tested negative by STAT, but 3 were positive by ELISA. The three abattoir workers were clinically normal, and lacked historical connections with clinical cases. This study illustrates the importance of microbiological, parasitic and residue monitoring as critical components of a hazard analysis and critical control point based system for game meat. The study also provides the basis for increased integrated health research, surveillance and meat safety risk analysis.
AFRIKAANSE OPSOMMING: Die Namibiese wildbedryf raak toenemend groter soos die produksie en verbruik van wildsvleis toeneem. Die verwante gesondheidsrisiko’s wat die gebruik van wildsvleis en verwante produkte vir mens en dier inhou, is nog nie volledig geassesseer nie. Die doelwit van die studie was om ondersoek in te stel na die potensiële gesondheidsrisiko's wat wildsvleis en verwante neweprodukte vir mens en dier inhou deur middel van die assessering van vleisgehalte en die bepaling van die rol van die wildsvleis spesies in die oordrag van soönoses. Die mikrobiologiese gehalte en veiligheid van uitvoer wildsvleis was geassesseer. Geen verskille in die aerobiese plaat telling (APC) vir monsters versamel tydens 2009 en 2010 is aangeteken nie. Die gemiddelde Enterobacteriaceae telling was 1.33± 0.69log10 cfu/cm2 in vergelyking met 2.93±1.50log10 cfu/cm2 tussen die jare. Onbeduidende heterotrofe plaattelling (HPC) vlakke is waargeneem in 9/23 water monsters, terwyl fekale bakterieë (d.i. kolivorme, Clostridium perfringens en enterokokke) nie in enige van die monsters geïsoleerd is nie. Sewe serogroepe, met die uitsondering van O26, is aangeteken vir die eksotiese spesies. Monsters verky van ʼn white tailed deer is as positief vir 'n serotipe van O45 getoets, en die teenwoordigheid van die stx1 geen is bevestig. In springbok het 5/15 poele van fekale monsters positief getoets vir die intimien geen. Geen Salmonella spp is geïsoleer nie en alle E. coli geïsoleer in die vleismonsters was negatief vir die Stec virulensie geen (d.i. stx1, stx2, EAE en hlyA). ʼn Liniêre regressie-analise is op geselekteerde veranderlikes wat as die belangrikste indikators kan dien, en enige moontlike interaksie wat die pH van wildsvleis 4 uur na-slag kan beïnvloed, uitgevoer. In 'n toenemende orde van grootte gedurende die winter tyd, die pH teen 16-36hr na slagting in springbok hart, lewer, milt, niere en longe was aansienlik hoër as die pH 6.0, terwyl geen beduidende verskille waargeneem is wanneer dit met die regulasie verwysingswaarde van die hart (pH 6.0) vergelyk is nie. Daar was 'n positiewe assosiasie tussen die pH van wildsvleis 4 uur na-slag en mate van aansameling in die lewer. Die pH van wildsvleis 4 uur na-slag, het toegeneem met 0.11 eenhede per mL toename in lewer aansameling en afgeneem met 0.04 eenhede per minuut toename in die skiet tot uitbloei interval, ongeag die spesie. Wurmeiers van rondewurms, Strongyloides papillosus, Toxocara spp, Trichuris spp en koksidia het in verskillende ladings in die mis van beide springbok en gemsbok ontlasting, voorgekom. Dit dui op 'n potensiële risiko van oordrag na ander spesies in die ekosisteem. Die voorkoms van ʼn nuwe parasiet, Skjabinodera kuelzii, in wildskarkasse is aangeteken en was geassosieer met inguinale fascia en renale vet, maar die openbare gesondheidsrisiko bly onduidelik. Daar word aanbeveel dat dié parasiet as ʼn potensiële risiko faktor tydens roetine vleisinspeksies beskou moet word. ʼn Totaal van 12 310 springbokke is oor 'n tydperk van twee jaar van 26 kommersiële plase geoes. Weefselmonsters (d.i. 60 lewers, 41 niere en 52 agterkwart spiere) is ewekansig versamel van gesonde diere. Die gemiddelde waardes (d.i. hoër as die opsporingslimiet) van kadmium (Cd) en lood (Pb) was 0.10 ± 0.05mg/kg en 1.04 ± 0.21mg/kg in die lewer onderskeidelik en 0.33 ± 0.22mg/kg en 0.905 ± 0.51mg/kg in die niere van springbok, onderskeidelik. Die vlakke van kadmium en lood in die agterkwart spiere was laer as die opsporingslimiet. Serum monsters (n=1692) is van skape, bokke en beeste van vier vermoedelik hoë risiko plase en springbok (Antidorcas marsupialis, n=900) van 29 gemengde boerdery sisteme versamel en getoets vir die teenwoordigheid van Brucella teenliggaampies deur middel van die Rose-Bengal-toets (RBT). Positiewe gevalle is bevestig deur die komplement binding toets (CFT). Die voorkoms van menslike brusellose is bepaal deur 137 abattoir werknemers te toets vir Brucella teenliggaampies deur gebruik te maak van die standaard buis agglutinasie toets (STAT) en die ensiembinding immunosorberende toets (ELISA). Beeste en skape van die vier hoë risiko plase het negatief getoets met die RBT en CFT metodes, maar bokke van twee van die vier plase het seropositief getoets (26/42 en 12/285 onderskeidelik). Nadoodse ondersoek van seropositief bokke het geen patologiese letsels aangedui nie. Die kultuur van orgaanmonsters van seropositief diere vir Brucellae was negatief. Die monsters versamel van wild het negatief getoets deur middel van die RBT en CFT toets metodes. Die voorkoms van brusellose in mense in die studie was geassosieer met die gebruik van ongepasteuriseerde melk, tuisgemaakte bokmelkkaas en koffie met ongepasteuriseerde melk, asook direkte kontak met bokke. Alle abattoir werknemers (n=137) het negatief getoets met die STAT metode, maar drie werknemers het positief getoets met die ELISA metode. Die drie abattoir werkers was klinies normaal en het nie vorige kontak met bevestigde kliniese gevalle gehad nie. Hierdie studie bevestig die belang van mikrobiologiese, parasitiese en residu monitering as kritieke komponente van 'n gevaar-analise en kritiese kontrolepunt gebaseerde stelsel vir die produksie en verbruik van wildsvleis. Die studie verskaf ʼn basis vir toekomstige navorsing gefokus op ʼn geïntegreerde benadering van mens- en diergesondheid, monitering en vleis veiligheid risiko-analises.

The aim of this research was to explore how participants made meaning in an environmental education and training course for people from industry, business and local government in South Africa, and to identify and comment on any constraints to this meaning-making. I used a Symbolic Interactionist theoretical framework to explore and comment on the meaning-making process. I started my research by conducting a questionnaire to select participants for interviews. During the course the selected participants were interviewed, as well as the two course co-ordinators. Data was also gathered during the course from participant observation field notes ('captured talk'), photographs, participants' assignments and course evaluations. The data was analysed using an adapted form of discourse analysis and matrices. The research highlights that the opportunities provided on the course were adequate for encouraging meaning-making amongst both the co-ordinators and participants. However, recorded instances of meaning-making were low, which indicated that there were certain constraints during the meaning-making process. This research highlights and comments on identified constraints such as time and workplace support. The research supports similar findings which emerged from research conducted on the Gold Fields environmental education course for teachers and also offers recommendations for further research and practice into meaning-;making within the field of environmental education and industry, business and local government in South Africa.

Texte intégralRésumé :
Self-regulatory Code of Conduct has widely been adopted by international brands to manage CSR issues in apparel and footwear supply chain for the last 2 decades. Increasingly, more apparel and footwear brands started to expand CSR scope to include environmental management in their supply chain. However, only very few international brands have disclosed their efforts on environmental management in their supply chain. This study aims to find out how apparel and footwear brands implement environmental management in their supply chain. Furthermore, what motivates them to carry out environmental management, and lastly, what challenges the industry encounters in carrying out effective environmental management. Primary and secondary data research were carried out in this study. Primary research, in a form of self-administered survey, was conducted for 11 brands and 15 of their respective suppliers. Secondary research was conducted through desktop research to gather additional information from brands, NGOs, academic studies and news.
The study revealed environmental management in apparel and footwear supply chain is becoming more important. However, most of the brands’ approaches on environmental management are loose (i.e. lack industry-wide sustainably environmental management strategy), and small in scope (i.e. first tier supplier only). It is suggested apparel and footwear brands should improve effectiveness of environmental management program in their supply chain, by applying different implementation strategies internally, with both brands’ and suppliers’ governments, suppliers as well as their stakeholders.published_or_final_version

Texte intégralRésumé :
Thesis (DTech (Design))--Cape Peninsula University of Technology, 2016.This thesis is an investigation into environmental sustainability in the South African fashion industry, with a particular focus on the role of design therein. The fashion and textile industry is a significant contributor to the South African economy and a major user of human and natural resources. It is through the use of resources – natural, constructed and human – that the industry is also supposedly damaging to the natural environment and the people working within it. Notable authors on environmentally sustainable design and, in particular, environmentally sustainable fashion design, seem to suggest that a holistic approach to environmental sustainability is fundamental to the implementation thereof. Design has the ability to direct change, and thus design and designers have the potential to drive holistic sustainable practices in the fashion system.The question this research therefore poses is what the role of environmental sustainability should be in a design-driven approach in the South African fashion industry; interrogated through an exploratory and descriptive case study. The case study consists of three purposively selected sub-units that operate within an environmentally sustainable focus in their fashion businesses, and that design, produce, and retail fashion products. The aim of the research was to explore, through a snapshot of the South African fashion system, the implementation of environmental sustainability in the fashion industry in South Africa, in order to determine what role fashion design practice can have in developing environmental sustainability in the fashion system.The most notable finding of the research highlights the immense difficulty of operating as a fashion business from an environmentally sustainable focus in South Africa due to the lack (and unsuitability) of resources that can be considered environmentally sustainable. The declining textile industry of South Africa makes it either almost impossible, or very costly, to work within an environmentally sustainable framework, and is a major impediment in the implementation of environmental sustainability in praxis. Therefore, those businesses that decide to operate within an environmentally sustainable framework do so because of inherent personal values and ethics.The second aspect identified in the survey of scholarship and underpinned by the findings, is a need for a transformative approach with regard to design praxis and how design praxis can influence consumer eco-consciousness. The research concludes with a recommended framework that suggests a holistic and integrated approach to design-driven environmental sustainability in the South African fashion industry, and elaborates on the role of the fashion designer in the implementation of environmental sustainability in the fashion system. The holistic and integrated approach should extend into fashion design education, requiring a fundamental shift in current fashion design education in South Africa.

Texte intégralRésumé :
The introduction of environmental and social issues into the boardroom is one of the greatest challenges of our time. The threat of climate change adds urgency to the challenge, with the costs of inaction on climate change estimated at between 5 to 20% of global GDP, leading to a global recession.
In terms of managing environmental and social concerns, the tourism industry, and the hotel and resort industry, has lagged behind other industries such as utilities, chemicals and banking and investment. Globally an estimated 5% of all CO2 emissions can be attributed to tourism. Energy use in hotels is disproportionately high, thanks to energy intensive facilities such as spas, laundries and swimming pools.
The global hotel and resort industry can thus make significant contribution to reduce human impact on the global climate. This research develops a tool which helps the hotel and resort industry identify and manage non-financial risks such as environmental and social issues, and improve sustainable development of individual businesses and the sector as a whole.
The research focuses on Guangdong Province, China, the richest province in China in terms of hotel stock, hotel revenues and hotel employees. China herself will be the world’s biggest tourism market by 2020 and given its future growth forecasts is an important venue to study sustainable development.
Recognising the difficulty in precisely measuring aspects of social science such as non-financial risk and attitudes towards non-financial risk, the conceptual framework for the study uses the idea of a working non-financial risk management approach towards the production of a set of working propositions useful for business. The study first identifies stakeholders; develops a non-financial risk management methodology to identify, measure, examine and prioritise risks, and then presents the conclusions as working propositions for corporations to use. Recommendations for industry are developed and presented.
To achieve the development of the non-financial risk management tool, the research draws a fresh link between risk management, corporate environmental management, sustainability and non-financial risk management. Second, through three research studies, a detailed investigation into the use and practice of sustainability and non-financial risk management is undertaken across 15 hotels in Guangdong Province. The first study is a comprehensive set of detailed in-depth interviews with 79 industry-specific stakeholders. The interviews are coded and the results used to develop the second study, a questionnaire survey of 351 hotel guests and 70 industry-specific stakeholders. A third study executes in-depth case-studies and non-financial risk benchmarking across 15 hotel and resort facilities. The results of all three studies are triangulated for better accuracy and understanding.
The study presents a number of working propositions for corporations to adopt as starting points for their own non-financial risk management strategies. It is found that there is generally low awareness and application of non-financial risk management in the hotel and resort industry in Guangdong. The industry-specific stakeholders and guests have very different priorities in terms of non-financial risk management, while resource conservation does emerge as the leading issue amongst industry-specific stakeholders and hotel guests. Cost savings are found to be the main driver for implementing non-financial risk management, while cost of implementation is the main barrier. Through a factor analysis, it becomes clear that two distinct factors are at play in the guest domain: guests’ own well-being and self-need; and wider social or environmental concerns.
The study recommends a multi-stakeholder partnership as a value-added framework for public policy, and recommends further research into stakeholder theory in China’s hotel and resort industry.published_or_final_version

Texte intégralRésumé :
Energy is essential to economic prosperity and quality of life. However it can have detrimental effects on the environment if not used properly. Moreover, if energy resources are scarce in a given country, then its use will impose economic and financial burdens on the national economy. The cement industry is energy-intensive, which adds a micro dimension to the macro issues mentioned above. Reducing energy consumption without due consideration to production requirements is not an optimal situation. What is needed is to arrive at a situation whereby energy is used rationally. The concept of rational use of energy has two embedded principles. The first is increased energy-use efficiency and the second is environmental protection. Jordan Cement Factories (JCF), located in a developing country where energy resources are not indigenously available and, therefore, costly energy requirements are imported, have realised the importance of addressing the energy management and conservation issues. This thesis describes the efforts initiated and conducted by the author, to address the research problem of improving energy usage through the application of effective management techniques aimed at reducing energy consumption per unit of cement produced. This present research has been concerned with energy management and efficient use of energy. The Jordan Cement Factories were used as a vehicle to demonstrate the proposed research methodology that aimed at improving energy consumption and thus operational efficiency. The methodology is based on establishing statistically significant relationships between interacting problem factors, and assessing the economic impact of improving these factors. Economic evaluation entailed the development of economic models and an application methodology combined with illustrative case studies. Consequently, the problem of energy management has been presented in a wider perspective that addressed the whole management system at the organisation. Towards that end, it was first necessary to show the significance of energy cost with respect to the overall manufacturing costs. The analysis of production costs, which demonstrated the significance of energy costs, was followed by the investigation and examination of the basic management factors that have direct impact on energy consumption at the JCF. Among these factors are, for instance, production line availability, production rate, average number of stoppages, and average duration of stoppages. These factors were determined using preliminary data analysis and the experience and technical knowledge of the researcher. The statistical analysis proved the existence of strong relationships between energy consumption and management factors. Several models were developed for a set of selected production lines, in the JFC at Fuhais and Rashadiya plants. These statistical models were generated using actual data for electrical energy and fuel consumption. The derived models have demonstrated the existence of strong relationships between energy consumption and management control factors; for instance, the values of R2 range from 60% to 90%. This implies that an equivalent percentage of the variations in energy consumption can be attributed to the selected management factors. The economic model developed in this research is concerned with demonstrating that effective management practices associated with proper maintenance and housekeeping can result in highly significant savings in energy usage. Although a simplistic methodology was used to evaluate the economic impact of any improvement programme, the economic treatment showed that the cost of improvement is actually negligible compared to the realisable savings in energy usage. The research has dealt with the details of developing a coherent energy management model whose objective is to establish transformational management processes of certain high-level management factors into daily operations and controls. The high-level management .factors are the same factors used as independent variables in the statistical and economic models, which statistically proved to be the major factors affecting the energy consumption at JCF. The research has also presented a detailed analysis of the organisational and procedural aspects of energy management with concentration on management functions, especially planning, controlling, executing, organising, and auditing. A detailed mapping and analysis of these functions as the main components of an Energy Management System (EMS) resulted in establishing job descriptions, organisational charts, work instructions and procedures for all-important functions of the EMS. The type of work described in this thesis could be extrapolated for application in other industries, particularly energy-intensive ones, to arrive at the objective of rational use of energy at the national and international levels. Comprehensive studies would need to be carried out for each type of industry prior to implementation. The cost benefit analysis presented in this research proved, beyond any doubt, the importance of implementing the EMS in JCF. As a result of this implementation it is demonstrated that huge annual savings were realised. Finally, as a result of improving energy control factors, introducing energy conservation measures and employing management techniques at JCF to guarantee the effectiveness of all such activities, resulted in an annual savings amount to about USS 3.5 million. Therefore, if the same or similar actions are undertaken by all cement, or other highly energy intensive industries then the savings could reach billions of dollars.

Cape Peninsula University of TechnologyEnvironmental management is a new phenomenon, one which affects not only the way that individuals live their lives today but also how businesses operate. Environmental policies cannot simply be introduced, especially in the hospitality industry. Although the industry thrives off customer satisfaction, like any other business it relies on making a profit each financial year for it to stay operational. This research was undertaken to determine if implementing an environmental policy has any effect on the financial statements of a select group of hotels within the Cape Metropole. In answering this question, the researcher was able to establish what the relationship between implementing environmental management policies was and the effect it has on the financial side of a specific group of hotels. “Hotels are also being pressured to move towards triple bottom line reporting (3bl), involving the relationship between profit, people, and planet” (Kleindorfer, Singhal & Van Wassenhove, 2005:482). “To encourage an environmentally more responsible behavior in the hotel sector, it was necessary to demonstrate the cost savings of these practices” (Bohdanowicz, 2005:188-205). The research methodology consisted of both quantitative and qualitative approaches. Interviews were conducted with participants from key organizations, and with people who were linked to the hotel industry and environmental management. These included government organizations, SARS, which deals with all tax-related laws in South Africa, Eskom, the country’s energy providing company, as well as with a travel agency which deals with hotel bookings on both a local and international level. A focus group was also undertaken to ensure that the problems being researched were discussed fully by likeminded people, and by those who were directly involved with carrying out these policies in hotels. Questionnaires were sent to all the four- and five-star hotels within the Cape Metropole to assess the current situation relating to environmental management and their financial profit or loss. The research determined that implementing environmental policies has both a positive and negative effect on financial statements, thus proving that there is a direct link between the two. The findings clearly showed that environmental policies, whilst good for the surroundings and the environment, can be financially draining for a business if not properly planned prior to implementation. With correct research, however, this can be done in the correct manner, with results that are positive for both the environment and for the company’s financial statements.

Texte intégralRésumé :
Sustainable development has become a popular trend in today's world with many national governments recognizing the severe environmental damages caused by inappropriate economic development. Cooperating with international organizations, national governments are working together to deal with the global environmental issues. In addition, sustainability has also been identified in the local development. Development strategies at the local level cause a significant change in the improvement of environment conservation, enhancement of life quality and emphasis on the harmony of society. To achieve local sustainability, industries in local communities will be confronted with challenges. This dissertation aims to investigate the relationship between local industry and sustainable city, using a case study of traditional tea industry in Hangzhou city. The research is carried out by surveys and interviews to tea farmers, local government officers and tea researchers. The dissertation shows that the implementation of sustainability in the tea industry at local level is active, but faces challenges of environmental degradation and fake tea.published_or_final_version

Texte intégralRésumé :
This dissertation examines the shrimp industry in the Gulf of California from a political ecology perspective. The interaction between fishermen and their marine environment is explored, as well as the historical factors that led to vastly different types of fishermen in the communities of Guaymas and Empalme. Some have specialized in the harvesting of shrimp; others are diversified, multiple species fishermen. Some are highly industrialized offshore shrimpers; others are small-scale fishermen, more modest in their technology but more resilient when facing the current crisis in the shrimp industry. The underlaying causes of this crisis are explored by looking at state development policies, the assumptions behind fisheries management, and the configuration of markets. These have all emphasized specialization in the production of shrimp while ignoring the high interannual variability characteristic of shrimp populations. The end result: an overcapitalized, overexpanded industry and a possible overexploitation of shrimp stocks. Rather than addressing the root causes of the crisis, recent policies have instead transferred rights to the offshore fishery from cooperatives to private investors. At the same time there has been a concerted attack against small-scale producers. It is believed that by getting rid of this sector, catch per boat in the offshore sector will increase and overall "efficiency" will be improved. I compare industrialized trawlers and the small-scale sector and argue that the latter is currently producing high quality shrimp at lower monetary and ecological costs. But small-scale fishing is not equated with sustainability. Instead, differences among small-scale fishermen are analyzed. I contend that those who belong to traditional fishing families and have access to collective knowledge about the marine environment that has accumulated through generations, are better able to deal with a highly unpredictable environment and minimize risk. Those who do not have access to this knowledge have specialized in the harvesting of shrimp. I argue that a strategy of diversification is both more profitable in the short-term and sustainable in the long-run. Avoidance strategies among small-scale fishermen in response to externally imposed regulations are also examined. Fishermen are analyzed as individual profit maximizers and as community members who break the rules to serve collective interests. Just as individuals act collectively to deal with an unpredictable environment, they also act collectively to effectively challenge the institutions of rule-making.

Texte intégralRésumé :
The start-up and step-up operation of two 16-liter, continuously operated, upflow anaerobic reactors receiving baker's yeast wastewater is presented in this thesis. The two reactors (A and B) were almost identical in construction. Reactor A was a conventional upflow anaerobic sludge blanket (UASB) reactor, and reactor B was a hybrid reactor. In addition to all the features of a UASB reactor, a fixed-film structure was installed in the mid section of the reactor B. Both reactors were operated at 35 °C and at a constant hydraulic retention time of 7 days. The waste strength, expressed in chemical oxygen demand (COD), was varied from 8 g COD liter⁻¹ (during the start-up) to 58 g COD liter⁻¹. The organic loading rate ranged from 1.1 to 9.4 g COD liter⁻¹ day⁻¹. The start-up lasted for the first 46 days. Towards the end of the start-up, methane production rates of 0.23 and 0.28 liter CH₄ liter⁻¹ day⁻¹ and COD reductions of 62.2% and 67.2% were achieved at organic loading rates of 1.1 and 1.3 g COD liter⁻¹ day⁻¹ for reactors A and B respectively. During the step-up operation, maximum methane production rates were, for reactors A and B respectively, 0.91 and 0.95 liter CH₄ liter⁻¹ day⁻¹ at organic loading rates of 5.8 and 6.4 g COD liter⁻¹ day⁻¹. In addition, reactor profiles for sludge concentration, pH, volatile fatty acids, and COD are also presented.Applied Science, Faculty of

Texte intégralRésumé :
Extended producer responsibility (EPR) as a holistic approach to product stewardship has been increasingly incorporated into environmental policy agenda in the last two decades. One major expectation of EPR is to prevent environmental problems at source by providing appropriate incentives for product eco-design changes. However, available studies empirically examining the actual influence of EPR on eco-design are limited. This research therefore aims to fill the research gap by evaluating the effectiveness of existing EPR programmes in driving eco-design changes from the perspective of China’s electrical and electronic (EE) industry, and shed some light on the prospects of EPR development in China.
Based on the analytical framework developed from reconstructed intervention theory, three intensive empirical studies have been carried out. The first study examines the perception and responses of 50 China’s EE manufacturers regarding the EU EPR programmes (i.e. the WEEE and RoHS Directives). The second study investigates the responses of 36 China’s EE manufacturers to the Chinese EPR programmes (i.e. China WEEE and China RoHS legislation) and identifies possible factors that exert causal impact on the occurrence of eco-design. In order to gain a deeper insight into the practical manifestations of effective EPR implementation in the private sector, three company case studies have been conducted in the third stage of the research, serving as an important supplement to the first two studies.
The three studies show that EPR programmes in a stringent regulatory approach focusing on products’ environmental properties such as substance bans can exert strong influence on design changes. However, mandated recycling legislation seems to have little driving effect for companies to change product design. The research points to the weakness of collective producer responsibility that is currently adopted in many EU Member States for WEEE implementation in achieving continuous eco-design improvements. It highlights the significance of realising the principle of individual producer responsibility in EPR programmes for achieving this goal.
Based on an attributability assessment, the research further shows that there are a number of factors that influence the adoption of eco-design in China, and the link between legislative EPR programmes and eco-design is complex and evolving. Not only may the EPR programmes have different existing, anticipating and potential effect on the incorporation of eco-design, but they may have very different driving influence on environmental laggards and leaders.
In this regard, this research suggests that there is no one-stop solution for EPR in China. A mixed mechanism that integrates various policy instruments such as administrative, economic and informative instruments, in conjunction with cooperation and infrastructure facilities, would be the most effective means to implement EPR in the context of China, thereby achieving the goal of sustainable production and consumption.published_or_final_version

Texte intégralRésumé :
Environmental issues seem to be one of the most important topics in the globalised world. Organisations of all sizes are subject to pressure from suppliers, customers and governments to be more environmentally responsible. This research focuses on implementation of an Environmental Management System (EMS) in the automotive industry, both internationally and in South Africa, and examines the background and concepts of the International Organization for Standardization (ISO), as well as the key implementation phases associated with the implementation of an EMS, in accordance with ISO 14001. The problem statement of this research is to determine if it is possible to transfer, apply and sustain environmental concepts to small, medium or large organisations. The primary objectives of this research, therefore, were to determine: does implementation of an EMS provide economic benefits to organisations; what drives an organisation to first implement an EMS; does implementation of an EMS improve environmental awareness and performance; and what implementation barriers are faced by small, medium and large organisations. To achieve these objectives, a literary review and an empirical survey were conducted. The survey consisted of an electronic, self-administered questionnaire that was circulated to respondents at various automotive organisations. Data collected from completed, returned questionnaires were analysed and graphically presented to complete the research and achieve the primary research objectives toward solving the afore-mentioned problem statement. Based on the findings of this research, it can be concluded that there is much to gain from implementing an EMS.

Texte intégralRésumé :
Thesis (MPhil)--Stellenbosch University, 2012.ENGLISH ABSTRACT: The main aims of this thesis were to focus on the restaurant system in Cape Town with a view to creating a support mechanism for a move to more sustainable practices. A review of the literature found that despite a growing global population, the pressure on resources and consumption has been driven by the global middle class. Over half the world lives in cities and dualistic urban systems reinforce access to resources by excluding the poor and favouring the wealthy. Resource flows and consumption have degraded ecosystems, created waste and emissions. We use resources faster than they can be replenished and have exceeded the earth’s regenerative capacity. Counter to this, there is evidence of decoupling resource use from economic growth. Similarly, the industrialised food system has been created on external inputs such as fertiliser and insecticides, largely derived from fossil fuels. Food produced in the system uses energy, produces waste, depletes the soil and thwarts biodiversity. The global food system counters local food economies. This thesis argues that a sustainable system would have the economy as a basis for a better and equitable environment for current and future generations within ecological and regenerative capacity. As a city Cape Town reflects the inequalities and unsustainability of the global system, with vast disparities in wealth and opportunity. Restaurants can control flows of energy, food and waste, support people and the environment, as well as communicate and educate consumers. By collaborative efforts they can lay the basis for local food economies. Restaurants connect consumers to their food and make decisions about where the food comes from, how it will be prepared and disposed of and who will engage in that preparation. The restaurant sector can contribute to sustainability in its use of resources as well as its employment, community engagement and communication practices. This in turn supports local economies and impacts on the broader sustainability of the city. Research into the restaurant system in Cape Town showed that there is consumer interest in sustainability. There is evidence of restaurants making efforts towards sustainable endeavours. Within Cape Town there is the opportunity to look for more sustainable energy, work around local and seasonal menus, support local food economies, and control wastage. Local food economies can be supported while staff can also be treated fairly and given growth opportunities. Endeavours can be communicated as a way of shifting current unsustainable consumption patterns. The conclusions drawn from the thesis suggest that like the Sustainable Restaurant Associations (SRA) and Dinegreen there is space for a support mechanism for the restaurant industry where individual restaurants can be helped to move to sustainability and collaborate with other stakeholders. The recommendations of the thesis are to create an organisation that can evolve into a co-operative that will bring restaurants together and map out the changes they make. They need to be supported with expertise and audits of their current practice so that they can set goals for the future with regard to their environmental and social actions.
AFRIKAANSE OPSOMMING: Die hoof doel van hierdie dissertasie was om die restaurantstelsel in Kaapstad te ondersoek met die oog daarop om ‘n ondersteuningsmeganisme vir meer volhoubare praktyke te skep. ‘n Literatuuroorsig het getoon dat ten spyte van ‘n groeiende wereldbevolking, die druk op natuurlike en ander hulpbronne deur die wereldwye middelklas uitgeoefen word. Meer as die helfte van die wereld woon in stede en dualistiese stedelike stelsels versterk toegang tot sulke hulpbronne deur die armes uit te sluit en voorkeur te gee aan die reikes. Die vloei en verbruik van hulpbronne het ekologiese stelsels gedegradeer en afskeidings en afval vergroot. Ons verbruik hierdie hulpbronne vinniger as wat hulle vervang kan word en het die aarde se herstelkapasiteit oorskry. Aan die ander hand is daar bewyse dat die verbruik van hulpbronne ontkoppel is van ekonomiese groei. Insgelyks is die industrieele voedselstelsel gegrond op externe inset soos kunsmis en insekdoders, wat grootendeels van fossiele brandstof bekom word. Voedsel wat in hierdie stelsel geproduseer word verbruik energie, skep afval, put die grond uit en werk biologiese verskeidenheid tee. Die globale voedselstelsel is in teenstand teenoor plaaslike voedselekonomiee. Hierdie dissertasie redeneer uit die oogpunt dat ‘n onderhoudbare stelsel die ekonomie as ‘n basis vir ‘n beter en billike omgewing vir huidige en toekomstige geslagte, binne die ekologiese kapasiteit, sou he. Die stad Kaapstad weerkaats die ongelykhede en onvolhoubaarheid van die wereldwye stelsel, met sy ongelykhede in welstand en geleenthede. Restaurante kan beheer uitoefen oor hulle vloei van energie, voedsel en afval, kan mense en die omgewing ondersteun, sowel as verbruikers inlig en oplei. Deur pogings om saam te werk kan hulle die grondslag le vir plaaslike voedselekonomiee. Restaurante kan verbruikers verbind tot hulle voedsel en kan besluite neem oor waarvandaan die voedsel verkry word, asook hoe dit berei en afgedoen sal word en wie dit sal berei. Die restaurantsektor kan bydra tot volhoubaarheid in sy gebruik van hulpbronne sowel as inwerkneming, gemeenskapsbetrokkenheid en kommunikasiepraktyke. Dit sal op sy beurt dan plaaslike ekonomiee ondersteun en ‘n wyer impak he op die volhoubaarheid van die stad. Navorsing oor die restaurantstelsel in Kaapstad het getoon dat die verbruiker belang stel in volhoubaarheid. Daar is tekens daarvan dat restaurante pogings aanwend in die rigting van beter volhoubaarheid. In Kaapstad bestaan die geleentheid om te soek na meer volhoubare energie, rondom seisoenaangepaste spyskaarte, die ondersteuning van plaaslike voedselekonomiee, en die beheer van afval. Plaaslike voedselekonomiee kan ondersteun word terwyl werknemers regverdig behandel word, en moontlikhede tot vooruitgang het. Hierdie pogings kan oorgedra word as ‘n manier om die huidige onvolhoubare verbruikspatrone te verander. Die afleidings wat gemaak word in hierdie dissertasie stel voor dat daar plek is vir ‘n ondersteuningsmeganisme vir die restaurantindustrie, soos die “Sustainable Restaurant Associations” (SRA) en “Dinegreen”, waar die individuele restaurant gehelp kan word in rigting volhoubaarheid te beweeg en om saam te werk met ander belangstellendes. Hierdie dissertasie stel voor om ‘n organisasie te skep wat kan ontwikkel tot ‘n kooperatiewe wat restaurant saam kan bring en die veranderings wat hulle aanbring kan uiteensit. Hulle sal moet ondersteun word met kennis en ouditering van hulle huidige praktyke, sodat hulle doele kan stel vir die toekoms met betrekking tot hulle omgewings en sosiaal gerigte handeling.

Texte intégralRésumé :
The logistics industry is an imperative component of trade and a major contributor to economic growth in many countries. However, the logistics activities come along with severe negative environmental impact, particularly in freight transport which is considered the most important source of environmental hazards in a logistics system. Even though 3PLs have a key role in the logistics industry, only a limited number of studies have been conducted to analyze the greenness of their activities. Therefore, this study is done with the aim to examine the greenness of 3PLs in Hong Kong and to understand the key barriers that they face during green logistics implementation.
This empirical research is conducted through case studies with eight 3PLs. An analytical framework which consists of eight green transport measures and nine influencing factors is developed to facilitate the research.
The findings suggest that green logistics is evolving in the 3PL industry Hong Kong but it is still at a preliminary stage. It also shows that the number of green transport measures adopted by 3PLs in Hong Kong is lower as compared to the analyzed 3PLs’ headquarters in other countries. The study further reveals that 3PLs in Hong Kong tend to adopt those measures which directly bring cost benefits to the companies, such as, eco-driving, load factor optimization, route optimization and fleet management. Nevertheless, measures which require financial investment or trade-off of profit margin/operational efficiency, for example, fleet modernization and modal shift are not commonly adopted. Moreover, some of the green measures, such as, green fuel or vehicle are not adopted by the case companies simply because they are unavailable in Hong Kong.
A number of practical barriers are derived from the case analyses. They are considered the main causes of slowing down green logistics development in the 3PL industry in Hong Kong. While different stakeholders play a role in overcoming the hurdles of the green logistics development, the Government is found to be the most influencing one as it can influence external as well as some of the internal barriers elicited by this study. Therefore, it should take a leading role in eliminating the barriers. At the same time, in order to comprehensively facilitate the progress of green logistics development, efforts and commitments from other stakeholders, i.e. 3PLs, industry associations and customers are required.published_or_final_version

Bourdeau, Jean Pierre. « Professional environmentalism in Canadian chemistry : the greening of a discipline ? » Thesis, McGill University, 1991. http://digitool.Library.McGill.CA:80/R/?func=dbin-jump-full&object_id=61115.
Texte intégralRésumé :
This research focuses on the involvement of chemists in professional Canadian environmentalism. We confront opposed research and development sector perspectives (government, industry, and university) to describe how incompatabilities between them resist cross-sectoral interaction and limit disciplinary greening. We then refer to original questionnaire and interview data to discuss the greening force of professional associations on a multisectoral discipline (chemistry). Finally, we consider plausible research avenues in the sociology of environment to address the current and future status of environmental chemistry.
