A extração de produtos florestais é uma estratégia de sustento importante para populações que vivem próximas a remanescentes de florestas tropicais. Entre estes produtos, a carne silvestre é fonte importante de proteína e renda monetária. A sobreçaca, no entanto, pode levar à extinção local de espécies, comprometendo a integridade das florestas tropicais e o sustento de populações humanas. Como consequência, pode também levar à diminuição do valor atribuído às florestas pelos moradores, incentivando a sua conversão a outras formas de uso da terra. Sabe-se que fatores econômicos, como renda monetária e riqueza, são determinantes importantes da caça e do consumo de carne silvestre. Porém, tem sido sugerido que o efeito destes indicadores econômicos dependa do contexto ambiental - em especial, a cobertura florestal, associada à disponibilidade de animais para caça e a distância ao centro urbano, associada ao acesso a outras fontes de renda e proteína - e do contexto cultural, em particular, a região de origem dos moradores. No entanto, estudos prévios não consideraram todos estes fatores simultaneamente. Além disso, pouco ainda se sabe sobre qual o valor atribuído às florestas por populações rurais e sua relação com a caça e o consumo de carne silvestre. Através de questionários estruturados aplicados por meio de entrevista à população rural de uma região extensa e heterogênea na Amazônia oriental, esta tese teve como objetivos investigar: (i) o efeito de fatores ambientais em maior escala como determinantes da caça e do consumo de carne silvestre (Capítulo 1); (ii) a importância relativa e as interações entre fatores em escalas distintas - econômicos, culturais e ambientais - na determinação da caça e do consumo de carne silvestre (Capítulo 2) e; (iii) se a caça e o consumo de carne silvestre, bem como o desmatamento, que pode comprometer esse recurso, estão associados à percepção do valor das florestas (Capítulo 3). No Capítulo 1, os resultados indicam que fatores ambientais são determinantes mais importantes da caça do que do consumo de carne silvestre, que é mais frequente que a caça, sugerindo a relevância do compartilhamento e/ou comércio como formas de obtenção de carne silvestre. Enquanto o consumo de carne de silvestre foi um pouco mais frequente em áreas remotas e mais florestadas, a caça foi mais frequente em áreas mais florestadas, mas também em áreas mais próximas a centros urbanos. Assim, os resultados sugerem que é improvável que a pressão de caça diminua com a crescente migração para áreas urbanas que hoje se observa na Amazônia. O Capítulo 2 traz evidências de que o consumo de carne silvestre, e principalmente a caça, dependem não só do contexto ambiental, mas também do cultural, e que os efeitos de indicadores econômicos dependem de fatores ambientais. A caça e o consumo de carne silvestre foram mais frequentes nas famílias de origem na região Amazônica, entre aqueles que dependem mais de atividades de subsistência, e ambos aumentaram com a renda monetária em áreas próximas a centros urbanos e/ou menos florestadas, mas diminuíram com a renda monetária em áreas remotas e/ou florestadas. Isto sugere que o sucesso de intervenções econômicas que visem tanto à redução da pobreza quanto à conservação da biodiversidade depende do contexto ambiental, e é muito mais provável em áreas mais florestadas e remotas. Os resultados do Capítulo 3 indicam que a quantidade de carne silvestre consumida influencia positivamente a percepção do valor utilitário da floresta, enquanto que a quantidade de florestas remanescentes no entorno influencia positivamente a percepção de seu valor intrínseco. Assim, para além de estratégias que visem o bem-estar humano via incentivos econômicos, há oportunidade para iniciativas que considerem outros aspectos do bem-estar associados aos serviços providos pela floresta - sejam recursos como a carne silvestre ou benefícios culturais e estéticos. Ao mesmo tempo, os resultados apontam o potencial de um perigoso ciclo de desvalorização da floresta, em que o desmatamento leva a diminuição da percepção do seu valor, que, por sua vez, pode agravar o desmatamento, indicando a urgência de investimentos em iniciativas de conservação nas paisagens mais alteradas / The extraction of forest products is an important livelihood strategy for human populations living in and around tropical forest remnants. Among these products, bushmeat is an important source of protein and monetary income. However, overhunting can lead to local species extinction, compromising the integrity of tropical forests and the livelihoods of human populations. As a consequence, it can also lead to a decrease in the value local people attribute to forests, further promoting land conversion. It is well known that economic factors, such as monetary income and asset-wealth, are important drivers of bushmeat hunting and consumption. However, it has been suggested that the effect of economic factors depend on the environmental context - especially forest cover, associated with game availability, and distance to urban centers, associated with alternative sources of protein and income - and on the cultural context, particularly the region of origin of residents. Nevertheless, previous studies did not consider all these factors simultaneously. In addition, little is known about the value attributed to forests by rural populations and its association with bushmeat hunting and consumption. Using questionnaire-based interviews with the rural population of a wide heterogeneous region in eastern Amazonia, this thesis aimed at investigating (i) the effects of large-scale environmental factors as drivers of bushmeat hunting and consumption (Chapter 1); (ii) the relative importance and interactions between factors at different scales - economic, cultural and environmental - in driving bushmeat hunting and consumption (Chapter 2) and; (iii) whether bushmeat hunting and consumption, as well as deforestation, which may compromise this resource, are associated with the perception of forest values (Chapter 3). In Chapter 1, the results indicate that environmental factors are more important drivers of hunting than of bushmeat consumption, which is widespread, suggesting significant bushmeat sharing and/ or trading. While bushmeat consumption was slightly more likely in remote and more forested areas, hunting was more likely in more forested areas but also in areas closer to urban centers. These results suggest that hunting pressure is unlikely to decrease with the increasing migration to urban areas nowadays observed in the Amazon. Chapter 2 brings evidences that bushmeat consumption, and especially hunting, depend not only on the environmental context but also on the cultural context, and that the effects of economic variables depend on environmental factors. Bushmeat hunting and consumption were more likely in households with Amazonian origin, with greater reliance on subsistence activities and both increased with monetary income in less remote and/or less forested areas, but decreased with monetary income in more remote and/or more forested areas. This result suggests that the success of economic interventions aiming at both poverty alleviation and biodiversity conservation depend on the environmental context, and is more likely in more forested and remote areas. The results of Chapter 3 indicate that the amount of consumed bushmeat positively influences the perception of forest instrumental value, while forest cover in the surroundings positively influences the perception of forest intrinsic value. These results suggest that, beyond strategies that aim at human well-being through economic incentives, there is opportunity for initiatives that consider other aspects of well-being associated with services provided by forests - whether resources such as bushmeat or cultural and aesthetic benefits. At the same time, the results suggest the potential for a dangerous reinforcing cycle of forest depreciation, in which deforestation erodes perceptions of forest values, which may in turn facilitate further deforestation, indicating the urgent need to invest in conservation initiatives in more altered landscapes

本研究的目的是希望從教科書傳播的角度去了解其中所傳遞的環境價值觀與態度訊息為何？隱含了哪些環境倫理以及呈現主題為何？更重要的是透過研究者對臺北市某國小四年級教科書內容的分析，再以開放式問卷、焦點團體訪談及個別訪談的方式了解此國小四年級全體學童對教科書中環境價值觀內容的接收與解讀情形，並初探國小中年級學童可能有的環境價值觀樣貌。 研究結果發現各領域教科書中「環境價值觀與態度」相關內容出現次數多寡依序為國語、自然與生活科技、社會、藝術與人文、綜合活動；且教科書內容偏向呈現「定位人和自然的關係」以及「關心人類行為的衝擊」兩大主題，而中年級學童對此的解讀亦大致符合，但對於呈現環境價值觀內容的認定和研究者的分析並不完全相同，這可能是因為中年級學童會依據長期從各方接收的訊息觀點，如實際生活經驗、課文情境安排、個人興趣與喜好、自然保育或迷思觀點、個人環保行動及不同環境倫理觀點等因素，進一步與教科書內容連結而歸納出其對人與自然環境關係的詮釋結果。 雖然教科書需改進其未完全達到環境教育課程綱要中希望破除人類中心價值觀的立場，但多數學童並非全盤接收教科書訊息，少部分學童亦能以批判性的觀點解讀教科書；而學童對於教科書的解讀與定位人和自然環境之間的關係則呈現三種環境倫理並陳的情況，甚至人類中心與生態中心倫理兼而有之的矛盾，這是否和教科書內容及主流社會價值觀亦存在此兩種對立的環境倫理並陳的現象有關，值得後續研究長期深入探討。 / This study investigated the environmental values and attitudes conveyed in textbooks as well as the environmental ethics implied and how they are presented. Analysis was conducted on the content of fourth grade textbooks in an elementary school in Taipei City, Taiwan. The reception and interpretation of the environmental values in the textbooks by the fourth grade students at the school was gained by using open-ended questionnaires, focus group interviews, and individual interviews. The findings of this study were as follows. The academic subjects with the most content involving environmental values and attitudes were Mandarin, science and technology, social studies, arts and humanities, and integrative activities. Relevant content in the textbooks was mostly directed at defining the relationship between man and nature and discussing concerns regarding the impact of human behavior. The interpretation of students was broadly identical to this result. Students in fourth grade link textbook content with long-term messages and points of views such as those derived from actual experience, the arrangement of scenarios in past textbooks, personal interests, nature conservation, misconceptions, personal environmental action, and environmental ethics in order to interpret for themselves the relationships between man and nature.

Η συγκεκριμένη μελέτη, διερευνά εκτενώς τις αξίες στα Νεοελληνικά αναγνώσματα εξαταξίου Γυμνασίου περιόδου 1940-1950, το θεματικό και ιδεολογικό περιεχόμενο τους, σε μια ιδιαίτερη ιστορικό-πολιτική φάση της πολεμικής και μεταπολεμικής Ελλάδας. Η έρευνα έδειξε ότι ανάλογα με τις πολιτικές και θρησκευτικές συνθήκες στα Νεοελληνικά αναγνώσματα έμπαιναν κείμενα που αποσκοπούσαν στην προαγωγή των σκοπών που επεδίωκε η πολιτική κατάσταση. Η εσωτερίκευση αξιών ήταν επιλεκτική για να υπηρετηθούν οι εκάστοτε σκοποί της εξουσίας. Αξίες που βοηθούν στη πολιτικοποίηση όχι στη κομματικοποίηση δεν προωθούνται σε αυτά τα κείμενα. Παρατηρούμε ότι το σύστημα αξιών της περιόδου αυτής είναι μια σύνθεση εθνικών, θρησκευτικών και ηθικών αξιών. Ο κεντρικός θεματικός πυρήνας των κειμένων παραμένει σχετικά σταθερός, με βασικό άξονα προσανατολισμού την πατρίδα, τους Ελληνικούς τόπους, τη φύση, τη θρησκεία και την οικογένεια. Το αξιολογικό περιεχόμενο στα αναγνωστικά της περιόδου αυτής επικεντρώνεται στην προβολή κυρίως εθνικών, θρησκευτικών και ηθικών αξιών. Εμφανίζει περισσότερο έναν εθνοκεντρικό, παραδοσιακό και συντηρητικό προσανατολισμό αξιών, που ανταποκρίνεται στη συντηρητική υφή της κυρίαρχης ιδεολογίας της εποχής εκείνης, και μεταβάλλεται σε μια συστηματική προσπάθεια κατήχησης και δογματικού διαποτισμού. Όλες οι αξίες συνεργάζονται και αλληλοσυμπληρώνονται, και τελικά αποτελούν ένα ενιαίο ιδεολογικό σύστημα αξιών, συμβατό με την ιδεολογία του εκπαιδευτικού συστήματος, που ηγεμονεύεται από την κυρίαρχη ιδεολογία του πολιτικοκοινωνικού συστήματος. / This study explores at length the values in Modern Greek Literature readings six-grade secondary Gymnasium period 1940-1950, the thematic and ideological content in a particular historical-political phase of the war and the post-war Greece. The investigations showed that depending on the political and religious conditions the texts had aimed at promoting the objectives pursued by the political situation. Thus was selective internalization of values to serve the respective objects of power. Values that help politicization rather than political parties are not promoted in these texts. Notice that the value system of this period is a synthesis of national, religious - moral values. Central core theme of the text remains relatively stable, with the main orientation axis of the homeland, the Greek places, nature, religion and family. The evaluative content to readers of this period show mainly focuses on national religious and moral values. It displays a more ethnocentric, traditional and conservative orientation of values, which correspond to conservative texture of the dominant ideology of the time, and changes in a systematic effort indoctrination and dogmatic indoctrination. Altogether the values complement each other, and ultimately form a single ideological value system, compatible with the ideology of the educational system, which overmaster by the dominant ideology of social and political system.

This thesis provides a comparative analysis of the environmental values present in Ghana’s and Senegal’s coastal regions, and the implications that those have for the surrounding environment. The countries approaches to urban farming, mining and oil and gas extraction, fishing, marine debris and municipal waste management are assessed in order to reach a greater understanding of these environmental issues. In undertaking this thesis, I attempted to draw a correlation between the handling of these issues and how people perceive their environment. Through the comparison of environmental degradation and the level of effort to achieve a more sustainable developmental framework in both countries, I draw examples from successes in Senegal’s coastal management framework to recommend appropriate environmental policy for the Greater Accra Region.

En av de viktigaste frågorna i världen idag är naturresurshantering. Med en väx-ande befolkning och hoten från klimatförändringar kommer förvaltningen av jordens naturresurser bli än viktigare, såväl för dagens generation som kommande generationer. En viktig aspekt när det gäller naturresurshantering är hur människor uppfattar och värderar naturen. För att komma närmare dessa miljövärden har ett flertal olika vetenskapliga tillvägagångssätt föreslagits. Den här avhandlingen undersöker hur det är möjligt att närma sig miljövärden under olika omständighe-ter och utifrån olika behov. Detta görs genom att undersöka hur olika teorier har använts, och kan användas, avseende olika våtmarker i Kenya. I utvecklingslän-der har naturresurser, teoretiskt sett, ett högre värde eftersom fattiga människor till en högre grad är direkt beroende av naturresurser och ekosystemtjänster. Ut-gångspunkten i denna avhandling är sex våtmarksområden i Kenya under olika förvaltning och med ett flertal, både aktuella och potentiella, användare. I av-handlingen undersöks hur lokalsamhället, myndigheter, industrier och turister uppfattar och värderar våtmarkerna. Genom att applicera ett arenaperspektiv, som betonar vikten av tvärvetenskap, diskuteras i avhandlingen det ekonomiska värdet av miljön för att sedan applicera andra metoder såsom emergy analys, stakeholder analys, kulturteori och riskanalys för att bredda och berika värderingen av miljön. / One of the most important issues in the world, both for present and future genera-tions, concerns natural resource management. With a growing global population and the threat of climate change, issues relating to natural resource management will grow in importance with time. One fundamental aspect of natural resource management is how people perceive and value the environment. The value that is ascribed to natural resources will be one of the determinants in the choices that people face in regards to their management. A wide range of approaches have been suggested to approach environmental values. This thesis focuses on analys-ing the assessment of environmental values under different circumstances and needs. This is done by exploring the ways various theories have and can be used to approach natural resource valuation in different wetland management situations in Kenya. In the developing world the value of natural resources can, theoreti-cally, be seen as even higher than in the developed world, due to poor peoples’ direct dependency on their natural resources and the ecosystem services and goods that they provide. The point of departure in this thesis is six wetland areas with different management strategies and with multiple users. It examines how local communities, governmental authorities, industries and tourists perceive the value of the wetlands. By applying an arena perspective, that emphasises the need of interdisciplinarity, this thesis discusses the economic value of the environment and applies other methods such as, emergy analysis, stakeholder analysis, cultural theory and risk analysis, to enrich the valuation of environment.

The research in this study focuses on the role of environmental education activities in the clarification of environmental values in Grade 6 learners. The much discussed environmental crisis arose as a result of man's negative environmental behaviour. Human behaviour is a matter of choices based on environmental values. Environmental value clarification aims to raise learners' awareness of their own values and to increase their effect on the environment. It helps learners to explore their own values, to consider advantages and disadvantages, to accept that others' beliefs may vary from their own, and to align their own actions and behaviours with their personal beliefs. Using environmental education activities the researcher aims to help learners clarify their environmental values as environmental education activities can not only be interesting and fun, but can also have a powerful impact on students' interest in and awareness of environmental problems. As the clarification of environmental values contains a highly subjective component, use is made of a combined method research strategy. The quantitative research component takes place through a pre- and post-test test with an experimental and a control group. During the pre- and post-test a standardised questionnaire is used whilst the interventions take the form of an environmental education activity. A qualitative, collective case study design forms the qualitative part of the combined method, through observation during the activity and focus group interviews thereafter. Three schools that are part of the project "Education for sustainable living", where schools pay attention to the environment through the implementation of environmental management principles, were selected for participation. The findings indicate that learners that were exposed to the activity are confronted with their own environmental values and attitudes whilst being forced to seriously, honestly andcritically reflect on his / her own values regarding specific environmental issues in the activity. / Thesis (MEd (Curriculum Development))--North-West University, Potchefstroom Campus, 2013.

Face aux nouveaux problèmes relatifs aux barrières environnementales de nos jours, l'OMC se trouve dans une situation embarrassante : d'une part, elle est largement considérée comme le "centre de gravité" du contrôle des barrières environnementales, d'autre part, il existe encore de grandes lacunes dans la régulation relative à la valeur environnementale au sein de l'OMC, ce qui mettrait en cause l'efficacité du droit de l'OMC dans cette régulation. Sans un contrôle efficace, le système du libre-échange risque de se dégrader. C'est la raison pour laquelle nous avons choisi de consacrer une étude comparative aux barrières environnementales au commerce international dans le cadre de l'OMC. Pour tenter de trouver des solutions aux problèmes qui se présentent aujourd'hui en matière de barrières environnementales, nous devons nous interroger sur deux questions majeures. D'une côté, les nouvelles barrières environnementales relatives au changement climatique dépassent le cadre de l'OMC, le droit actuel de l'OMC ne paraît pas en mesure de donner une réponse satisfaisante aux problèmes qui en résultent, et de l'autre, il existe un grand écart entre les pays développés et ceux en développement au niveau des barrières environnementales mises en place, ce qui provoque des déséquilibres dans le commerce international. Les analyse que nous avons effectuées dans cette étude portant à la fois sur les ACR et l'OMC nous permettent de conclure que l'OMC jour un rôle irremplaçable face aux problèmes de barrières environnementales, cela nous conduit à proposer des solutions permettant au droit de l'OMC de mieux concilier le commerce international et la protection de l'environnement à l'échelle mondial / Facing the new problems about the green trade barriers today, WTO is actually in an embarrassing situation : one side, it is widely considered as the ''center of gravity' 'for controlling the green trade barriers ; on the other side, there is still an important lacuna in the regulation of the environmental values in the WTO, which questions the effectiveness of WTO's law in this regulation of green trade barriers. Without the effective control, the free trade system takes a risk to be degraded. That's the reason why we undertake a study comparative on the subject of the green trade barriers in the framework of WTO. Attempting to find the solution of the problems related to green trade barriers, we have to ask two questions. One side, the new type of green trade barriers about the climate change beyond the capacity of WTO, the current law of WTO does not appear to give a satisfactory response to the resulting problems ; on the other side, there is a big gap between the green trade barriers set up by the developed countries and developing countries, which causes absolutely an imbalance in the international free trade. The analyse that we did in this study relating both to the regional trade agreements and WTO allow us to conclude the WTO plays an irreplaceable role in face of challenges of the green trade barriers today. This conclusion leads us to propose the solutions which may offer a better balance between the international trade and the environmental protection on a global scale
