This dissertation is an attempt to analyse and address some of the many and complex issues revolving around protected area - community relationships. The success of these relationships are essential if the mission of protected areas are to be achieved. Due to large scale agriculture, high density populations and environmental degradation protected areas are often looked upon as a means to conserve biodiversity. It is for this reason that they play an important role in the natural environmental of South Africa. However, there is a growing realisation that protected areas will not survive unless they become relevant to the communities that surround them. These cOI11nlunities are often characterised by high density populations and low levels of infrastructural and economic development. These developmental requirements need to be considered by protected area management, and a dedicated effort is required by protected areas to assist in meeting these needs. However, the relationship between protected areas and C0111nlunities should not simply focus on meeting the developmental needs of the community, relationships need to allow for communities to participate in decisions and activities that directly impact of their lives. Benefits need to accrue to communities from protected areas for them to support the concepts of conservation. Benefits need to be tangible, intangible and empowering for them to have real meaningful impacts on the communities. Communities need to be actively involve in all aspects of the protected area management and links need to be forged between conservation and development, so that the socio-economic condition of those living closest to protected areas improves. This study uses the relationship between Mthethomusha Game Reserve and the surrounding Mpakeni conmunity, and the Pilanesberg National Park and the neighbouring Bakgatla community to investigate many issues, including the manner in which communities participate and benefit from conservation. The findings of this study reflect that the relationships between communities and protected areas are dependent on a number of factors including~ ownership~ socio-economic condition of the surrounding community~ institutional structures and capacity of the community formal agreements; history of the fonl1ati~n of the protect~d a~ea~ reliance on the protected area for survival and the meaningfulness and appropriateness of the benefits received from the protected area. The experiences of the two case studies has been analysed and compared to develop a theoretical model for community - protected area relationships. This model indicates the primary prerequisites which will contribute to effective and equitable relationships between protected areas and surrounding communities. / Thesis (M.Env.Dev.)-University of Natal, Pietermaritzburg, 1999.

In recent years the use of tourism as a development strategy by third world governments has increased, resulting in the intersection of international tourism and local agricultural strategies. The aim of this thesis is to critically assess the impact of tourism development on local agriculture in the Okavango Delta in Botswana. More specifically, the study appraises the current state of tourism and agriculture in the Okavango Delta, assesses the social, economic and environmental effects of tourism development on the Okavango Delta and its communities, examines local agricultural production and consumption patterns, assesses the patterns of supply and demand of food in the region, and evaluates the impact of tourism on local subsistence agriculture, while making use of both qualitative and quantitative data sources. The Okavango Delta region is faced with several socio-economic problems. These include high unemployment levels, unequal regional development, income inequalities and extreme levels of poverty. 'Rural-urban' migration by local subsistence farmers in search of formal employment opportunities has risen steadily since the early 1990s, resulting in unprecedented social changes to the inhabitants of the Delta, and the abandonment of traditional farming practices. This, together with the limited interaction between the local population and tourism industry, is increasingly leading to tension between local and foreign parties in the region. The large proportion of foreign owned tourist facilities and foreign investment results in major economic leakages, and the exclusion of Motswana from any form of meaningful participation in the tourism industry. The presence of foreign tourists in the Delta enforces the need for imports, increasingly damaging local agricultural production as both production and consumption becomes imported. If tourism is to be of any benefit to the local population in the Okavango Delta, there has to be local involvement and ownership. The fostering of linkages between tourism and other sectors, particularly agriculture, is imperative in attempting to bring about socio-economic growth in this region. / Thesis (M.A.)-University of Natal, Pietermaritzburg, 2003.

This dissertation is dedicated to study the design and utilization of financial contracts and pricing mechanisms for managing the demand/price risks in electricity markets and the price risks in carbon emission markets from different perspectives. We address the issues pertaining to the efficient computational algorithms for pricing complex financial options which include many structured energy financial contracts and the design of economic mechanisms for managing the risks associated with increasing penetration of renewable energy resources and with trading emission allowance permits in the restructured electric power industry. To address the computational challenges arising from pricing exotic energy derivatives designed for various hedging purposes in electricity markets, we develop a generic computational framework based on a fast transform method, which attains asymptotically optimal computational complexity and exponential convergence. For the purpose of absorbing the variability and uncertainties of renewable energy resources in a smart grid, we propose an incentive-based contract design for thermostatically controlled loads (TCLs) to encourage end users' participation as a source of DR. Finally, we propose a market-based approach to mitigate the emission permit price risks faced by generation companies in a cap-and-trade system. Through a stylized economic model, we illustrate that the trading of properly designed financial options on emission permits reduces permit price volatility and the total emission reduction cost.

Thesis (MFor)--University of Stellenbosch, 2003. / ENGLISH ABSTRACT: The reliance of firewood demand on indigenous trees such as Acacia erioloba is a continuing phenomena despite the concern that over-exploitation of these resources will degrade the environment. This study tested the hypothesis that the cutting of A. erioloba in the Northern Cape is driven by (a) market demand in the Western Cape, (b) ignorance of the long-term ecological consequences and/or (c) ignorance of legislation along the chain of custody of this product. The assumption is that whoever is involved in the A. erioloba firewood industry (resource owner, trader or user) is neither aware of the protected status of the resource nor the negative consequences associated with the over-exploitation of the resource or they are driven by short term monetary gains. Therefore, there is a need to understand the needs of every participant in the chain and to further find out if there may be substitutes for A. erioloba firewood. The results of this study show that there is a market for firewood in the study area and that this demand is driven mainly by the availability rather than the quality of firewood. It will also be shown that Acacia mearnsii which is available in the study area is a better product than A. erioloba and therefore it can be a suitable replacement but consumers were found to bum almost everything that would give them embers. The most preferred firewood in the study area is A. cyclops. The concept of indigenous trees is not clearly understood by retailers and consumers. The major role players in the supply chain were found to be the retailers and the transport owners who may be targeted when firewood trade is to be stopped in the short-term. The results further highlighted the fact that the majority of consumers were aware that indigenous trees were protected in South Africa but the majority of retailers were not aware. The study recommends that firewood trade should be stopped completely by strict enforcement of the law or by the involvement of every role-player and/or that the trade should be regulated. / AFRIKAANSE OPSOMMING: Die fenomeen dat die aanvraag vir vuurmaakhout staatmaak op inheemse bome soos Acacia erioloba duur steeds voort ten spyte van die kommer dat oorbenutting van hierdie hulpbronne, ter versadiging van die behoeftes van 'n steeds toenemende populasie, die omgewing sal degradeer. Hierdie studie het die hipotese getoets dat die afsny van A. erioloba in die Noord- Kaap aangedryf word deur (a) die mark aanvraag in die Wes-Kaap, (b) onkunde oor die langtermyn ekologiese gevolge en/of (c) onkunde oor die wetgewing van hierdie produk by die skakels in die verskaffersketting. Die aanname is dat wie ook al betrokke is by die A. erioloba vuurmaakhout-industrie (hulpbron eienaar, handelaar of gebruiker) is beide onbewus van die beskermde status van die hulpbron asook van die negatiewe gevolge geassosieer met die oorbenutting van die hulpbron of hulle is aangedryf deur korttermyn monetêre gewin. Daarom is dit nodig om die behoefte van elke deelnemer in die ketting te verstaan en om verder uit te vind of daar plaasvervangers vir A. erioloba vuurmaakhout is. Die resultate van hierdie studie toon dat daar 'n aanvraag is vir vuurmaakhout in die studie-area en dat hierdie aanvraag hoofsaaklik gedryf word deur die beskikbaarheid, eerder as die kwaliteit van die hout. Daar salook aangetoon word dat Acacia mearnsii, wat in die studie-area beskikbaar is, 'n beter produk is as A. erioloba en dus 'n geskikte plaasvervanger kan wees, maar dit wil voorkom of die verbruikers omtrent enigiets sal brand wat kole sal verskaf. A. cyclops is die vuurmaakhout van voorkeur in die studie-area. Handelaars en verbruikers verstaan nie die konsep van inheemse bome duidelik nie. Die vernaamste rolspelers in die verskaffersketting is die handelaars en die eienaars van die vervoer en hulle kan die teikengroep wees as die handel in vuurmaakhout in die korttermyn stopgesit word. Die resultate het verder na vore gebring dat die meerderheid verbruikers daarvan bewus is dat inheemse bome beskermd is in Suid-Afrika, maar die meerderheid handelaars is nie hiervan bewus me. Hierdie studie maak die aanbeveling dat handel in vuurmaakhout totaal gestaak moet word deur strenger wette of deur die betrokkenheid van elke rolspeler en/of dat handel gereguleer moet word.

The Eden To Addo Corridor Initiative aims to connect formally protected areas in a conservation corridor from the coastal area of the Eden District near Plettenberg Bay, Western Cape, South Africa to the Addo National Elephant Park, Eastern Cape, South Africa. The corridor will incorporate government and privately owned land, and will be an attempt to maintain ecological processes at a range of spatial and temporal scales. The Langkloof Valley lies between the Baviaanskloof World Heritage Area and the Tstitsikamma National Park; two formally protected areas that will be incorporated into the Eden To Addo Corridor. Spatial prioritization analyses allow conservation planners to select areas that should be targeted for conservation action based on a range of criteria. Historically, ecological criteria have been included mostly alone in spatial prioritization. Recently, the idea of ‘conservation opportunity’ has emerged in the field of conservation planning; the notion suggests that a range of different types of data should be included in processes to spatially prioritise for conservation. By including those data defined as ‘human’ and ‘social’ data into prioritising activities, the feasibility of conservation plans can be accounted for, but historically conservation planners have failed to do so. I conducted a literature review that demonstrated that although the importance of human and social data are acknowledged in the conservation planning literature, these data that define opportunity are rarely actually included in spatial prioritisation analyses. I then carried out a social assessment that allowed me to define the social and human context of our study area and, specifically, what stewardship instruments land managers in the Langkloof would be prepared to engage. We found that land managers were generally willing to engage, but lacked the financial capacity to adopt conservation methods. Using a subset of the social and human data that were collected in the social assessment, I trialled a new Decision Support Software to fuse those data with ecological data in a novel attempt to identify priority areas for conservation action based on ecological integrity and feasibility. We also scheduled (ranked) land managers to approach for conservation action with a focus on local champions and clusters of land managers displaying strong conservation characteristics. Two corridors were identified; a major corridor in the western region of the valley and a secondary corridor closer to the middle. The members of the Initiative have been briefed on the outcomes, which provided them an opportunity to provide feedback; it is hoped that the framework of this study can be used for planning future connections. The Eden To Addo Corridor Initiative sent out a stewardship extension officer in February 2011 to approach those land managers areas that were identified. This planning exercise is a good demonstration of how, by collaborating effectively, academic conservation planners can contribute to supporting decision making by organizations that are implementing conservation action.

This study involved an issues-based approach to curriculum contextualisation in the context of the Eco-Schools programme in Kenya. It adopted a two-phase design using interpretivist and socially critical research orientations. In this study, research is represented as a process which is socially constructed within a particular theoretical, contextual, social and historical context by unfolding the thesis to illuminate how the phases are closely woven into each other. The first phase used the survey method for a contextual review of existing approaches and views relating to environmental education in the formal education sector. The survey aimed to develop a deeper understanding of environmental education as currently practiced in Kenya and to unravel the complexities surrounding it. It involved about two hundred and six primary school teachers and a critical review of a set of resource materials used in Kenyan Primary Schools. It revealed that some aspects of environmental education practice and the prevailing technocratic view of curriculum in Kenyan primary schools potentially limit possibilities for issues-based approaches to curriculum contextualisation. The action research process in four case study schools in Nyanza province of Kenya represent an attempt to address issues in context through socially critical environmental education. Participant observations, workshops and document analysis revealed that, contextualised conceptions of the terms ‘environment’ and ‘environmental education’ that resulted from a process of deliberation of meaning by teachers in relation to their contexts and practices served to set perspective for the action research process. Further, the planning phase which involved environmental auditing to identify issues of concern, prioritization of actions, issues to address, and action planning to guide implementation was critical in setting the agenda of the action research process in each of the case study schools. Integration and infusion of local issues of concern into curriculum planning further enriched processes of curriculum contextualisation, making them relevant to local contexts by addressing real issues through appropriate pedagogical approaches in auditing, investigation and research, communicating and interpreting results, reflecting on investigations and taking action. The action research process further enhanced cooperation and partnership between the case study schools and surrounding communities with mutual benefits. The research report demonstrates that despite the limitations posed by the technocratic orientation of the Kenyan curriculum, it is possible to address real environmental issues, risks and associated sustainable development challenges in context through issues-based approaches to curriculum contextualisation in the context of the Eco-Schools programme.

South Africa is recognised as one of the megadiverse nations of the world. In recent years, the South African Government has prioritised human needs, without adequately safeguarding the country’s natural resources. Biodiversity is the living fabric of our planet, responsible for human health, well-being and ultimately, the preservation of the environment. It is the Government’s responsibility to ensure that processes and policy frameworks recognise the significance of biodiversity and its role in ensuring a sustainable future for the country while at the same time ensuring essential services delivery to its people. The aim of this study was to evaluate the impact of environmental governance on biodiversity management at the local government level in South Africa. The study was conducted in three Metropolitan Municipalities in South Africa. Data were collected by means of a questionnaire from officials of these municipalities. Variables that were assessed include capacity assessment, intergovernmental relations, budget and biodiversity management. Interviews were conducted with the Heads of the environmental departments of the municipalities. A review of the defining national and international environmental law was conducted to evaluate the transformation, challenges and successes of biodiversity mangement at the local government level in South Africa. The results of this study highlight the challenges faced by local governments in implementing biodiversity management such as capacity constraints, lack of resources and the absence of a biodiversity mandate at the local government sphere. Integrating biodiversity management at the local level will only be possible through more robust policy development, stronger cooperation and communication among the different levels of government, as well as enhanced capacity (skills) and resource provision in the municipalities. / Environmental Sciences / M.

This paper outlines the current state of environmental legislation and administration in Botswana, identifying the various problems with that system. Those problems include fragmented and overlapping administration and out-dated legislation that is not in keeping with modem, holistic approaches to environmental management, ineffective and unreliable enforcement, compounded by rampant non-compliance. The paper then considers some the developments that are being made to improve this situation, including: the conversion of the environmental agency into a department and the introduction of an over-reaching environmental Act, preparation of a wetlands conservation strategy, the introduction of environmental impact assessment legislation. The paper concludes by querying the effectiveness of those developments when unsustainable attitudes continue to predominate in the country / Law / LL.M.

O tema central deste estudo refere-se à Construção Sustentável sob a ótica da preservação dos recursos naturais, perpassando pelos temas do papel da Construção Civil como agente transformador e regenerativo de seus impactos ecológicos na sociedade. Apesar dos já identificados limites planetários, no Brasil, a forma de entender a construção civil como agente de transformação social e econômica ainda não é favorável à manutenção do equilíbrio da natureza. Com características diferenciadas, o país apresenta prioridades de ação sobre o saneamento, a água, a exploração das florestas e a produção de alimentos que devem ser incorporadas em suas estratégias. Apesar do termo “construção sustentável” referir-se à preocupação ambiental no setor, a base comum do debate ainda é iniciante. Assim, objetivou-se analisar documentos publicados sobre as linhas prioritárias dos debates entre os agentes representativos do setor da construção civil brasileira para examinar os enfoques da Sustentabilidade Ecológica como base de sustentação para a vida no Planeta. Foram consideradas as contribuições das políticas públicas de “construção sustentável” para estimular a cadeia produtiva para ampliar a sustentabilidade. Acredita-se que este estudo pode promover uma análise da importância da Sustentabilidade Ecológica na “construção sustentável” por meio de produção de inovações, saberes e conhecimentos. A metodologia do estudo tem uma abordagem qualitativa, de natureza teórico-conceitual tendo como objeto de análise documentos públicos e privados. Identificou-se convergências e divergências nos debates relevantes para introduzir avanços na discussão. O conteúdo identificado nos documentos limita-se à importância da construção civil no desenvolvimento urbano e ao suprimento do consequente déficit habitacional sem referência aos grupos privilegiados, a exemplo do declarado na Agenda 21 para a construção sustentável em países em desenvolvimento. Quando se referem às ações alinhadas com o desenvolvimento sustentável, os textos abstêm-se de referências ao tema da inclusão social na habitação. As particularidades dos três documentos apresentam-se como verdadeiras e pertinentes para o setor da construção civil. Considerando o conteúdo dos documentos, as empresas que cuidarem da água, energia e do meio ambiente, podem ser mais competitivas e melhorar a sua produtividade e rentabilidade. Concluiu-se que os documentos são iniciativas de reflexões sobre o tema da Sustentabilidade Ecológica e fornecem orientações para o equilíbrio do desenvolvimento sustentável, o que pode ser alcançado mediante os princípios da economia circular aplicada à Construção Sustentável. Como sugestões para trabalhos futuros, esta Tese destacou a importância da economia circular como uma alternativa para aliar os interesses do desenvolvimento econômico e o desenvolvimento sustentável por meio da Construção Sustentável. / The central theme of this study refers to Sustainable Construction from the perspective of Ecological Sustainability, passing by themes of the role of Civil Construction as a transforming and regenerative agent of their ecological impacts in society. It is perceived a conflict between Ecological Sustainability and Sustainable Development due the later suggest economic growth with care for environment and social issues. Despite already identified planetary boundaries, in Brazil, the way to understand the Civil Construction as social and economic transformation agent is still not in favor of maintaining the nature balance. With different characteristics, the country presents action priorities on sanitation, water, forest exploration and food production that should be incorporated into their strategies. Although the term "sustainable construction" refer to environmental concern in the sector, the common basis of debate is still beginner. The objective was to analyze published documents on priority lines of discussions among representative agents of Brazilian Civil Construction sector to examine the focus of Ecological Sustainability as a support basis for life on the planet. It were considered contributions from public policies of "sustainable construction" to stimulate the production chain to increase sustainability. It is believed that this study can promote an analysis of the importance of ecological sustainability in "sustainable construction" through production of innovation, knowledge and expertise. The study methodology has a qualitative approach, theoretical and conceptual nature having as object of analysis public and private documents. It was identified convergences and divergences in debates relevant to introduce advances in the discussion. The content identified in documents is limited to the importance of civil construction in urban development and to supply resulting habitation shortage without reference to privileged groups, such as stated in Agenda 21 for sustainable development in developing countries. When referring to actions aligned with sustainable development, the texts abstain of references to the issue of social inclusion in habitation. The particularities of the three documents are presented as true and relevant to the construction sector. Considering documents content, companies that take care of water, energy and the environment, can be more competitive and improve their productivity and profitability. It was concluded that the documents are initiatives of reflections on the theme of Ecological Sustainability and provide guidance for the balance of sustainable development, which can be achieved by the principles of circular economy applied to Sustainable Construction. As suggestions for future works, this thesis emphasized the importance of circular economy as an alternative to align interests of economic development and sustainable development through Sustainable Construction.
