Cool Rationalities and Hot Air: A Rhetorical Approach to Understanding Debates on Renewable Energy.

A key obstacle to the wide-scale development of renewable energy is that public acceptability of wind energy cannot be taken for granted when wind energy moves from abstract support to local implementation. Drawing on a case study of opposition to the siting of a proposed off-shore wind farm in Northern Ireland, we offer a rhetorical analysis of a series of representative documents drawn from government, media, pro- and anti-wind energy sources, which identifies and interprets a number of discourses of objection and support. The analysis indicates that the key issue in terms of the transition to a renewable energy economy has little to do with the technology itself. Understanding the different nuances of pro- and anti-wind energy discourses highlights the importance of thinking about new ways of looking at these conflicts. These include adopting a “conflict resolution” approach and “upstreaming” public involvement in the decision-making process and also the counter-productive strategy of assuming that objection is based on ignorance (which can be solved by information) or NIMBY thinking (which can be solved by moral arguments about overcoming “free riders”).

Shedding Light on the light bulb puzzle: the role of attitudes and perceptions in the adoption of energy efficient light bulbs

Despite the potential energy savings and economic benefits associated with compact fluorescent light bulbs, their adoption by the residential sector has been limited to date. In this paper, we present a theoretical model that focuses on the agents' ability to perceive the correct cost of lighting and on the role of environmental attitudes as key determinants of the adoption decision. We use original data from Ireland to test our theoretical predictions. Our results emphasize the importance of education, information and environmental awareness in the adoption decision.

The role of the Professional Engineer in the 21st century

In light of the current world economic and environmental crisis due in part to
unsustainable development and poor financial planning, 21st Century engineers are faced with unprecedented challenges of developing a sustainable world in balance with the forces of nature to combat global environmental, social and economic crises. The European Union, the United States of America and a number of other countries have identified that smart solutions and highly skilled professionals are needed to survive climate change and create long-term prosperity. In this paper the evolution of the changing career of the engineer will be presented. The policy background to the current system of engineering education at bachelor’s and graduate level in Ireland will be introduced and perceptions of engineering as a profession by society in general, and by
school leavers selecting third level courses will be discussed. The role of the engineer as a specialist, expert or generalist will also be studied in terms of the changing demands and needs of society. Finally the responsibility of universities, through broad-based multidisciplinary teaching and training, to prepare the next crop of engineers will be examined.

Sustainability-related media coverage and socioeconomic development: a regional and North–South perspective

Abstract. With this paper we discuss the differences between sustainability-related media agendas across different countries and regions. Utilising a sample of 115 leading national newspapers covering forty-one countries, we show that typically no homogeneous global trends exist with regard to sustainability-related media agendas. Instead, significant differences exist regarding the national-level prioritisations of sustainability-related issues in the countries under review. To some extent, these observed differences can be attributed to different levels of socioeconomic development as measured by Human Development Index scores and gross domestic product per capita. Here, generic differences can be identified between newspapers from the Global North and South, with a range of issues such as climate change emerging as typically Northern issues, whereas issues such as corruption and poverty show significantly higher levels of coverage across newspapers from the Global South. We conclude with a discussion of the results in the context of global environmental governance.

A complete analytic theory for structure and dynamics of populations and communities spanning wide ranges in body size

The prediction and management of ecosystem responses to global environmental change would profit from a clearer understanding of the mechanisms determining the structure and dynamics of ecological communities. The analytic theory presented here develops a causally closed picture for the mechanisms controlling community and population size structure, in particular community size spectra, and their dynamic responses to perturbations, with emphasis on marine ecosystems. Important implications are summarised in non-technical form. These include the identification of three different responses of community size spectra to size-specific pressures (of which one is the classical trophic cascade), an explanation for the observed slow recovery of fish communities from exploitation, and clarification of the mechanism controlling predation mortality rates. The theory builds on a community model that describes trophic interactions among size-structured populations and explicitly represents the full life cycles of species. An approximate time-dependent analytic solution of the model is obtained by coarse graining over maturation body sizes to obtain a simple description of the model steady state, linearising near the steady state, and then eliminating intraspecific size structure by means of the quasi-neutral approximation. The result is a convolution equation for trophic interactions among species of different maturation body sizes, which is solved analytically using a novel technique based on a multiscale expansion.

A Strain-Driven Morphotropic Phase Boundary in BiFeO3

Piezoelectric materials, which convert mechanical to electrical energy and vice versa, are typically characterized by the intimate coexistence of two phases across a morphotropic phase boundary. Electrically switching one to the other yields large electromechanical coupling coefficients. Driven by global environmental concerns, there is currently a strong push to discover practical lead-free piezoelectrics for device engineering. Using a combination of epitaxial growth techniques in conjunction with theoretical approaches, we show the formation of a morphotropic phase boundary through epitaxial constraint in lead-free piezoelectric bismuth ferrite (BiFeO3) films. Electric field-dependent studies show that a tetragonal-like phase can be reversibly converted into a rhombohedral-like phase, accompanied by measurable displacements of the surface, making this new lead-free system of interest for probe-based data storage and actuator applications.

Changing the intellectual climate

Calls for more broad-based, integrated, useful knowledge now abound in the world of global environmental change science. They evidence many scientists' desire to help humanity confront the momentous biophysical implications of its own actions. But they also reveal a limited conception of social science and virtually ignore the humanities. They thereby endorse a stunted conception of 'human dimensions' at a time when the challenges posed by global environmental change are increasing in magnitude, scale and scope. Here, we make the case for a richer conception predicated on broader intellectual engagement and identify some preconditions for its practical fulfilment. Interdisciplinary dialogue, we suggest, should engender plural representations of Earth's present and future that are reflective of divergent human values and aspirations. In turn, this might insure publics and decision-makers against overly narrow conceptions of what is possible and desirable as they consider the profound questions raised by global environmental change.

Reclamações em matéria de ambiente nos municípios envolventes à ria de Aveiro

O presente trabalho de investigação centra-se no estudo das reclamações em matéria de ambiente submetidas às Câmaras dos municípios envolventes à Ria de Aveiro entre os anos de 2000 e 2007. Pretendeu compreender-se de que forma podem ser caracterizadas as reclamações, nomeadamente a análise temporal, os principais atores envolvidos na apresentação e na resolução das reclamações, os imputados pelos problemas ambientais levantados, as tipologias de problemas de ambiente associadas às reclamações, o padrão territorial que assumem e as resoluções aplicadas. Procurou ainda compreender-se até que ponto a existência de um ecossistema em comum aos municípios, a Ria de Aveiro, influencia os tipos de problemas ambientais que têm sido alvo de reclamações e quais são os fatores que determinam as semelhanças e as diferenças encontradas no estudo das reclamações por municípios. A metodologia do trabalho consistiu, sumariamente, na revisão da literatura da especialidade com o objetivo de identificar o que tem sido desenvolvido nesse ramo de investigação, na caracterização da área de estudo e no desenvolvimento de uma estrutura metodológica para a identificação e a análise das reclamações e para a ponderação dos resultados com as perceções dos líderes locais através da realização de entrevistas. O enquadramento teórico do estudo salientou os principais aspetos referidos no domínio dos protestos ambientais e das reclamações do público sobre o ambiente, bem como o quadro concetual relativo à governação ambiental local. Adicionalmente, descreveram-se um breve panorama dos protestos ambientais em Portugal, dos quadros legislativos Europeu e nacional assentes no direito de acesso à informação ambiental e no princípio da participação, bem como os procedimentos locais para a apresentação de reclamações ambientais. Apresentou-se também a caracterização dos municípios abrangidos, destacando-se os principais aspetos socioeconómicos, ambientais, de infraestruturação, os instrumentos de planeamento e de gestão do território e do ambiente e o enquadramento institucional relativo à gestão ambiental nos municípios, constituindo informações relevantes para o enquadramento da área de estudo e um suporte útil para a análise e a interpretação dos resultados. Os resultados obtidos permitiram evidenciar que, no geral, há um aumento do número de reclamações ao longo dos anos. Como principais atores envolvidos, foi possível destacar os munícipes como os mais participativos, tendo se revelado também como os principais responsáveis pelos problemas ambientais observados. Para além das Câmaras Municipais, as instituições policiais surgem como as principais entidades requeridas na resolução dos problemas. As reclamações refletem sobretudo problemas localizados e que interferem com o quotidiano dos cidadãos, tais como a limpeza de terrenos, os depósitos de lixo a céu aberto ou o saneamento básico. Os problemas enunciados tendem a concentrar-se nas áreas mais urbanizadas e com maior densidade populacional. A intensidade, a tipologia e a distribuição territorial das reclamações são também determinadas pelas fronteiras administrativas. Contrariamente ao esperado, a Ria não constitui um fator mobilizador de reclamações ambientais dirigidas às Câmaras Municipais. Os diferentes mecanismos de submissão de reclamações, as políticas e prioridades de gestão ambiental local, a par da perceção ambiental das populações, influenciam esses resultados. A análise da resolução das reclamações mostrou que, embora a maior parte tenha sido equacionada pelos governos locais, uma percentagem significativa permaneceu em aberto. Apesar de ter sido detetada uma relevante concordância entre os principais problemas de ambiente referidos nos planos municipais de ambiente ou das Agendas 21 Locais existentes, as reclamações informam sobre problemas que nem sempre estão considerados naqueles instrumentos e que requerem atenção por parte dos governos locais. Adicionalmente, a ponderação entre os resultados obtidos a partir do estudo as reclamações e as perceções dos líderes locais acerca das exposições do público mostra que, apesar de uma perceção consistente sobre os problemas ambientais dominantes, há ainda um caminho relevante a percorrer para consolidar os sistemas municipais de receção, tratamento e análise das reclamações. O estudo desenvolvido ressalta o potencial que as reclamações ambientais incorporam enquanto fontes de informação sobre a tipologia de problemas ambientais persistentes, a sua localização e os principais atores envolvidos. Essa informação é crucial no momento em que se desenvolvem ou reveem instrumentos locais de gestão e de planeamento ambiental. Ao destacar o potencial das reclamações em matéria de ambiente, o trabalho propõe um conjunto de recomendações que permitem às Câmaras Municipais enriquecerem o sistema de gestão da informação proporcionada pelas reclamações, a sua utilização, e, em consequência, melhorar as relações de confiança entre o público e a Autarquia e a própria a governação ambiental local.

Identifying and explaining framing strategies of low carbon lifestyle movement organisations

Over the last decade we have seen the growth and development of low carbon lifestyle movement organisations, which seek to encourage members of the public to reduce their personal energy use and carbon emissions. As a first step to assess the transformational potential of such organisations, this paper examines the ways in which they frame their activities. This reveals an important challenge they face: in addressing the broader public, do they promote ‘transformative’ behaviours or do they limit themselves to encouraging ‘easy changes’ to maintain their appeal? We find evidence that many organisations within this movement avoid ‘transformative’ frames. The main reasons for this are organisers’ perceptions that transformational frames lack resonance with broader audiences, as well as wider cultural contexts that caution against behavioural intervention. The analysis draws on interviews with key actors in the low carbon lifestyle movement and combines insights from the literatures on collective action framing and lifestyle movements.

Geographical Applications for Sound Walks

Geography has long been a predominantly visual discipline, but recent work in geography has sought to explore the multisensory, embodied, emotional and affective dimensions of people’s relations with places. One way to engage this type of exploration is through the use of sound walks: walks along a specified route accompanied by a soundtrack (on headphones or stationary speakers) that conveys information, enacts a story, produces an ambience or atmosphere, or illuminates certain aspects of the environment through which the listener is walking. This thesis aims to show how geographers can benefit from using sound walks as thinking tools, representational tools and teaching tools. Drawing on my own experiences producing sound walks, I first examine the ways that sound walk production processes help generate productive geographical thinking for those producing sound walks (Chapter Two). The various stages of producing a sound walk require different skill sets, pose different challenges, and require different sorts of environmental awareness, and therefore present novel opportunities for developing geographical insights about specific places or spatial relations. Second, I focus on four experientially-oriented aspects of sound walks – using multiple senses, walking, contingency, and moments of interaction – to argue that sound walks can be useful representational tools for geographers, whether those creating sound walks subscribe to a representational or non-representational theory of knowledge (Chapter Three). The value of sound walks as representational tools is in the experience of ‘doing’ them. That is, audiences discover for themselves through interaction what is being represented, rather than having it delivered to them. The experiential elements of ‘doing’ sound walks recommend them as potentially helpful representational tools for geographers. Third, by examining the work of a small sample of fourth year “Advanced Geography of Music” students, I develop the argument that sound walks can be effective tools for teaching students and for creating circumstances for students to learn independently (Chapter Four). Sound walks have potential to be effective pedagogical tools because they are commensurate with several key pedagogical schools of thought that emphasise the importance of requiring students to engage actively with their environment using a combination of senses. The thesis demonstrates that sound walks are a worthwhile resource for geographers to use theoretically, representationally and pedagogically in their work. The next step is for geographers to put them into practice and realize this potential.

Réfugiés climatiques : statut et traitement

L’état actuel des travaux ne rend pas compte de l’ampleur des questions philosophiques et des enjeux moraux suscités par l’apparition sur la scène internationale des réfugiés climatiques. Il est pourtant urgent de leur accorder une protection à travers des accords internationaux. Les philosophes qui se sont penchés sur le sujet ont été induits en erreur tant par la multiplicité des termes employés que leur absence de définitions. Ce travail critique la tendance actuelle des militants écologistes à vouloir englober des populations aux problèmes divers sous le terme de réfugié. Banaliser l’emploi du terme de réfugié n’est pas seulement fallacieux mais également dangereux. A terme, les militants se tourneront vers la Convention de Genève pour revendiquer que les populations déplacées soient considérées comme des réfugiés. Or la Convention de Genève n’est pas un outil adéquat pour remédier au sort de ces populations. De plus, on ne peut élargir le statut de réfugié pour inclure ces populations sans risquer de perdre sa crédibilité et son efficience. Suivre la pente qu’emprunte les militants nous mènerait à accorder le même traitement aux réfugiés climatiques et aux réfugiés politiques, ce qui est une erreur. Notre hypothèse est que les habitants des petits pays insulaires à l’inverse des autres populations ont besoin d’un élargissement de la Convention de Genève. Nous arguerons que nous avons des devoirs et des responsabilités envers eux que nous n’avons pas envers les réfugiés politiques. Pour défendre ce point de vue, il faut définir clairement ce qu’est un réfugié climatique et justifier cette appellation. Nous devrons donc confronter la notion de réfugié climatique à d’autres notions concurrentes. Une fois les termes définis, nous envisagerons les enjeux éthiques à travers le prisme des questions de justice globale. Nous verrons que pour déterminer qui devrait remédier au sort des réfugiés climatique, il ne suffit pas de se référer à la responsabilité causale. Cela nous mènera à arguer que bien que séduisant, le principe pollueur-payeur n’est pas un outil adéquat pour guider la réflexion. Nous serons également amenés à nous interroger sur la pertinence d’une institution environnementale globale.

Les représentations sociales et les préoccupations en matière d’environnement chez les jeunes du Sénégal : une étude comparative en milieu urbain chez les jeunes scolarisés de Dakar.

Le Sénégal est confronté à plusieurs enjeux environnementaux accentués par l’exode rural, la croissance démographique et l’urbanisation galopante. Dans la capitale de Dakar, les populations sont exposées à des risques industriels, sanitaires et environnementaux importants. Face aux conséquences néfastes des phénomènes de la dégradation de l’environnement en milieu urbain, il convient de chercher à mieux comprendre ce que l’environnement représente pour les populations notamment chez la jeune génération qui aura à vivre avec les conséquences liées à la détérioration de l'environnement léguée par les générations précédentes. S’appuyant sur la théorie des représentations sociales, cette recherche a comme objectifs 1) d’explorer les représentations sociales de l’environnement chez les jeunes sénégalais âgés de 9 à 16 ans en milieu scolaire situé en milieu urbain, et ce, dans différentes écoles de la ville de Dakar ; 2) d’étudier les connaissances, les sensibilités et les comportements des jeunes en matière écologique et environnementale; 3) finalement de déterminer les principaux agents responsables de la socialisation des jeunes dakarois en matière d’environnement. Le tout analysé en fonction de trois variables soit l’âge, le genre et le type d’école. La méthodologie de notre recherche est essentiellement qualitative de type exploratoire et elle s’appui principalement sur des questionnaires et des dessins. Les résultats montrent qu’en ce qui concerne les représentations sociales de l’environnement des jeunes dakarois, à travers l’analyse du discours, que l’environnement est représenté par les catégories typologiques dites « négative » « utilitariste » et « milieu de vie ». Ces représentations sociales varient à divers degrés en fonction du groupe d’âge, du genre et du type d’école. Les jeunes sont également nombreux à utiliser un vocabulaire associé aux notions liées à l’environnement naturel. De son côté, l’analyse picturale, qui concorde avec l’analyse lexicale, montre que les catégories typologiques de l’environnement sont liées au « milieu de vie », à l’« environnement ressource » et à l’« environnement nature » et ce, peu importe l’âge, le type d’école et le genre.

Il était une fois l’ailleurs-- le stage de coopération internationale comme espace de développement du cosmopolitisme et de la conscientisation des jeunes Québécois

Chaque année, quelques milliers de jeunes Québécois découvrent la coopération internationale, par le biais de stages dans des pays dits « en développement ». Si les retombées de ces stages sur les populations partenaires du Sud sont connues et régulièrement évaluées, il existe en revanche peu d'études de suivi des stagiaires à leur retour au Québec. Quel impact cette expérience a-t-elle eu sur ces jeunes? Quelles étaient leurs motivations au départ? Et comment leur engagement vis-à-vis des problématiques de développement a-t-il évolué ou s’est-il même maintenu suite à leur séjour? Comment leur expérience a-t-elle façonné leurs projets professionnels et leurs perceptions de l’avenir? Ce mémoire a pour objet de dresser un portrait de l’impact d’un stage de coopération internationale sur les jeunes stagiaires de retour au Québec. Pour ce faire, notre recherche s’appuie sur des données quantitatives et qualitatives recueillies auprès d’anciens stagiaires de l’ONG Mer et Monde. Les données quantitatives ont été collectées à l’aide d’un sondage effectué auprès de 367 anciens stagiaires et un entretien de groupe a fourni les bases qualitatives de la recherche. Les résultats de l’analyse suggèrent que le stage a très certainement une forte influence sur l’engagement et le mode de vie des jeunes à leur retour au Québec. À la suite de l’expérience à l’étranger, l’identité des enquêtés est notamment affectée par rapport à six aspects : l’ouverture sur le monde, la conscience écologique, la conscience sociale, le développement personnel, le rapport à l’« Autre », et les représentations de l’« Ailleurs ». Il apparait que ce sont tout autant les habitudes de vie, que le regard que les stagiaires portent sur le monde, qui se sont trouvés affectés. Et la spécificité d’une telle expérience et les processus à l’œuvre nous permettent d’assimiler ce type de stage à une expérience de développement du cosmopolitisme et de la conscientisation des jeunes Québécois.

Phytoplankton Pigment Signatures as a Biomarker in a Tropical Estuary

We are in the cutting edge of a new era of development without leaving any promises to next generation. But the scale and size of the problem are only partially blamed. The juggernaut of Globalisation has trampled upon whatever little hope we might have had making a quick transition to a less energy – intensive world. “Environment friendliness begins at home”. Our quest for productivity and profitability should progress simultaneous with our cooperative responsibility of leaving behind a clean and green earth for the generation to come. Climate change is the most pressing global environmental challenge being faced by humanity, with the quest for better productivity for our fragile ecosystem. It is too late to rely solely on reduction in Green house gas emissions to mitigate climate change although this is undoubtedly crucial. Coastal belts are more prone to these devastating impacts and its protection is an intensive filed of research. The present study describes how the colourful Carotenoids and Chlorophylls can be used in rapid hand on tool in conjunction with molecular biology to open sources and it also explores the fate of organic matter in the aquatic system and underlying sediments.
