Eco-touristic snorkelling routes at Marinha beach (Algarve): Environmental education and human impacts

The use of natural areas for underwater coastal marine activities such as snorkelling is growing, but the amount of ecological and socioeconomic data on these activities is scarce and relates mainly to coral reef areas. Three underwater self-guided routes were designed at Marinha Beach (Algarve, Portugal), based on scientific information, with in situ interpretation and guidance, as a way to enhance biodiversity awareness and, hence, reduce the probability of human impacts. The routes were implemented in two consecutive summer seasons and after each season, visual census techniques were used to describe flora composition and cover area (seaweeds and seagrasses) in order to understand patterns and evaluate human impacts. Snorkelers' opinions and perceptions about several issues related to the routes' environmental education role (e.g. role in enhancing biocliversity awareness) were investigated by questionnaire after the snorkelling activity. An inter-annual difference inflora assemblages was found, probably associated to natural variability, rather than snorkelers' impacts. Results indicate that, in fact, in situ education and interpretation can raise environmental awareness if properly addressed, resulting in a satisfactory way of engaging snorkelers in the protection and in the conservation of the visited environments, thereby preventing negative ecological impacts.

Assessing the energy efficiency of gear oils via the FZG test machine

Energy efficient lubricants are becoming increasingly popular. This is due to a global increase in environmental awareness combined with the potential of reducing operating costs. A new test method of evaluating the energy efficiency of gear oils has been described in this report. The method involves measuring the power required by an FZG test rig to run while using a particular test lubricant. For each oil that was being evaluated, the rig was run for 10 minutes at a load stage of 10. Six extreme pressure (EP) industrial gear oils of mineral base were tested. The difference in power requirements between the best and the worst performing oils was 2.77 and 3.24 kW, respectively. This equates to a 14.6% reduction in power, a significant amount if considered in relation to a high powered industrial machine. The oils of superior performance were noticed to run at reduced temperatures. They were also more expensive than the other products of lesser performance.

Information and communication technologies : catalysts for sustainable development

The concept of sustainable urban development has been pushed to the forefront of policy-making and politics as the world wakes up to the impacts of climate change and the effects of modern urban lifestyles. Today, sustainable development has become a very prominent element in the day-to-day debate on urban policy and the expression of that policy in urban planning and development decisions. As a result of this, during the last few years, sustainable development automation applications such as sustainable urban development decision support systems have become popular tools as they offer new opportunities for local governments to realise their sustainable development agendas. This chapter explores a range of issues associated with the application of information and communication technologies and decision support systems in the process of underpinning sustainable urban development. The chapter considers how information and communication technologies can be applied to enhance urban planning, raise environmental awareness, share decisions and improve public participation. It introduces and explores three web-based geographical information systems projects as best practice. These systems are developed as support tools to include public opinion in the urban planning and development processes, and to provide planners with comprehensive tools for the analysis of sustainable urban development variants in order to prepare the best plans for constructing sustainable urban communities and futures.

Ecological leadership : a new perspective on leadership

Given today's focus on the state of the environment and the developing role of corporate social leadership in could be argued that there is a need for the development of successful business leaders who have a positive relationship to the natural world. Gifford (2007) argued that any real change in sustainable practice will most likely happen at an individual level, through changes in attitudes and everyday behaviour. For this change to happen, an individual will need to feel connected to the natural world (Dunbar, 2004; Schroll, 2007). Roszak (1992) developed the notion of ecopsychology specifically to explore this relationship and suggest new ways to generate greater environmental awareness as well as ameliorate psychological problems caused or exacerbated by widespread alienation from nature. From this perspective it seems imperative that we develop people centred leader’s who feel connected to the natural world whilst demonstrating solid performance, as measured by organisational and social indicators. This paper presents information from an International research project that might add further insights into the role outdoor education plays in the development of generic leaders who have a positive relationship to the natural world. Three questionnaires, an established measurement of generic transformational leadership (MLQ) and two established measurement of attitudes to and feelings about the natural world (the New Ecological Paradigm Scale and the Connectedness to Nature Scale), were administered to 214 (males, n=138 and females, n=76) International outdoor leaders with the implicit aim of assessing the nexus of transformational leadership theory and adventure based leadership development. The large and diverse cohort of participants has provided ground-breaking insights into transformational and ecological leadership styles. This paper outlines a descriptive analysis of findings and offers valuable information for those involved in training leaders. Throughout this presentation participants will be encouraged to contextualise the information for their specific circumstance.

Determinants and consequences of information sharing with key suppliers

The economic environment of today can be characterized as highly dynamic and competitive if not being in a constant flux. Globalization and the Information Technology (IT) revolution are perhaps the main contributing factors to this observation. While companies have to some extent adapted to the current business environment, new pressures such as the recent increase in environmental awareness and its likely effects on regulations are underway. Hence, in the light of market and competitive pressures, companies must constantly evaluate and if necessary update their strategies to sustain and increase the value they create for shareholders (Hunt and Morgan, 1995; Christopher and Towill, 2002). One way to create greater value is to become more efficient in producing and delivering goods and services to customers, which can lead to a strategy known as cost leadership (Porter, 1980). Even though Porter (1996) notes that in the long run cost leadership may not be a sufficient strategy for competitive advantage, operational efficiency is certainly necessary and should therefore be on the agenda of every company. ----- ----- ----- Better workflow management, technology, and resource utilization can lead to greater internal operational efficiency, which explains why, for example, many companies have recently adopted Enterprise Resource Planning (ERP) Systems: integrated softwares that streamline business processes. However, as today more and more companies are approaching internal operational excellence, the focus for finding inefficiencies and cost saving opportunities is moving beyond the boundaries of the firm. Today many firms in the supply chain are engaging in collaborative relationships with customers, suppliers, and third parties (services) in an attempt to cut down on costs related to for example, inventory, production, as well as to facilitate synergies. Thus, recent years have witnessed fluidity and blurring regarding organizational boundaries (Coad and Cullen, 2006). ----- ----- ----- The Information Technology (IT) revolution of the late 1990’s has played an important role in bringing organizations closer together. In their efforts to become more efficient, companies first integrated their information systems to speed up transactions such as ordering and billing. Later collaboration on a multidimensional scale including logistics, production, and Research & Development became evident as companies expected substantial benefits from collaboration. However, one could also argue that the recent popularity of the concepts falling under Supply Chain Management (SCM) such as Vendor Managed Inventory, Collaborative Planning, Replenishment, and Forecasting owe to the marketing efforts of software vendors and consultants who provide these solutions. Nevertheless, reports from professional organizations as well as academia indicate that the trend towards interorganizational collaboration is gaining wider ground. For example, the ARC Advisory Group, a research organization on supply chain solutions, estimated that the market for SCM, which includes various kinds of collaboration tools and related services, is going to grow at an annual rate of 7.4% during the years 2004-2008, reaching to $7.4 billion in 2008 (Engineeringtalk 2004).

Mapping resilience : A framework for changing cities

Urban centres base their resilience on the ability to evolve and adapt as needed throughout their life. Although constantly developing, changing and subsuming nature for its needs, the current age of environmental awareness requires that cities progress in a more conscious and considered way. While they have become the dominant form of human habitation, there now exists a need to integrate 'green' solutions into urban centres to address social, physical and environmental wellbeing. The means of implementing the vast array of possible solutions without negative impacts is not clear; cities are complex systems, layering meaning, history and cultural memory ‐ they are a manifestation of shared cultural values, and as such, they do not allow a tabula rasa approach of 'blanket' solutions. All around us, cities are continuing to develop and change, and although their form is varied ‐ sprawling cities with density and sustainability problems; or collapsing cities with 'dead' centres and dilapidated districts – a common issue is the resilience of the local identity. The strength or resilience of cities lies in the elements which have become fixed points in the urban structure, giving character and identity to a shared urban experience. These elements need to be identified and either maintained or revitalised. Similarly, the identification of urban elements which can most viably be modified without compromising character and identity of place, will assist in making concrete contributions to increasing both the sustainability and experience of cities, making them more resilient. Through an examination of case studies, this paper suggests a framework to inform urban renewal assessing the widespread elements which generate an urban identity, beyond the traditional approach of heritage conservation for cultural or tourist purposes. The rapid contemporary alteration of urban structures requires an innovative methodology which satisfies on one side the need of new sustainable performances and, on the other, the resilience of the local character.

Domestic energy monitoring in Victorian households with PV solar installations : feasibility report for GV Community Energy

Australia requires decisive action on climate change and issues of sustainability. The Urban Informatics Research Lab has been funded by the Queensland State Government to conduct a three year study (2009 – 2011) exploring ways to support Queensland residents in making more sustainable consumer and lifestyle choices. We conduct user-centred design research that inform the development of real-time, mobile, locational, networked information interfaces, feedback mechanisms and persuasive and motivational approaches that in turn assist in-situ decision making and environmental awareness in everyday settings. The study aims to deliver usable and useful prototypes offering individual and collective visualisations of ecological impact and opportunities for engagement and collaboration in order to foster a participatory and sustainable culture of life in Australia. Raising people’s awareness with environmental data and educational information does not necessarily trigger sufficient motivation to change their habits towards a more environmentally friendly and sustainable lifestyle. Our research seeks to develop a better understanding how to go beyond just informing and into motivating and encouraging action and change. Drawing on participatory culture, ubiquitous computing, and real-time information, the study delivers research that leads to viable new design approaches and information interfaces which will strengthen Australia’s position to meet the targets of the Clean Energy Future strategy, and contribute to the sustainability of a low-carbon future in Australia. As part of this program of research, the Urban Informatics Research Lab has been invited to partner with GV Community Energy Pty Ltd on a project funded by the Victorian Government Sustainability Fund. This feasibility report specifically looks at the challenges and opportunities of energy monitoring in households in Victoria that include a PV solar installation. The report is structured into two parts: In Part 1, we first review a range of energy monitoring solutions, both stand-alone and internet-enabled. This section primarily focusses on the technical capacilities. However, in order to understand this information and make an informed decision, it is crucial to understand the basic principles and limitations of energy monitoring as well as the opportunities and challenges of a networked approach towards energy monitoring which are discussed in Section 2.

Challenges facing carbon dioxide labelling of construction materials

In the absence of a benchmarking mechanism specifically designed for local requirements and characteristics, a carbon dioxide footprint assessment and labelling scheme for construction materials is urgently needed to promote carbon dioxide reduction in the construction industry. This paper reports on a recent interview survey of 18 senior industry practitioners in Hong Kong to elicit their knowledge and opinions concerning the potential of such a carbon dioxide labelling scheme. The results of this research indicate the following. A well-designed carbon dioxide label could stimulate demand for low carbon dioxide construction materials. The assessment of carbon dioxide emissions should be extended to different stages of material lifecycles. The benchmarks for low carbon dioxide construction materials should be based on international standards but without sacrificing local integrity. Administration and monitoring of the carbon dioxide labelling scheme could be entrusted to an impartial and independent certification body. The implementation of any carbon dioxide labelling schemes should be on a voluntary basis. Cost, functionality, quality and durability are unlikely to be replaced by environmental considerations in the absence of any compelling incentives or penalties. There are difficulties in developing and operating a suitable scheme, particularly in view of the large data demands involved, reluctance in using low carbon dioxide materials and limited environmental awareness.

Reflections on the Research Students' 2015 Art Exhibition and Operetta/morality play "The Trial of Homo Economicus: The dollar hunting animal"

The paper outlines the process of organising research student participants and creating a public musical performance at QUT. The theme of the Operetta/Morality play is the clash between economic values of humans necessitating growth and the basic needs of the other life on planet earth. The one act play is set in a court room presided over by a judge who adjudicates the court proceedings.Homo economicus is in the dock and victims(various animals and birds) raise their grievances.

Grand Push Auto: A car based exertion game

Grand Push Auto is an exertion game in which players aim to push a full sized car to ever increasing speeds. The re-appropriation of a car as essentially a large weight allows us to create a highly portable and distributable exertion game in which the main game element has a weight of over 1000 kilograms. In this paper we discuss initial experiences with GPA, and present 3 questions for ongoing study which have been identified from our early testing: How might we appropriate existing objects in exertion game design, and does appropriation change how we think about these objects in different contexts, for example environmental awareness? How does this relate to more traditional sled based weight training? How can we create exertion games that allow truly brutal levels of force?

Bestimmung der Begriffe Gesamtfang, Fang, Beifang und Rückwürfe

Due to the increasing environmental awareness of the public, marine environmental protection became a general interest. Since fishery is one of the strongest direct influences of man on the marine ecosystem, it became criticised, especially because of the discarding of unused fish, which is considered as a waste of the resource. In the different types of fisheries the calculation of the amounts of discards in relationship to the landings vary strongly. One of the reasons is, however, the different use of the terms 'bycatch' and 'discard'. Thus it is important to work with equal terms and definitions, so that fishermen, protectionists and ecologists talk the same language. This contribution tries to define the following terms achieving a generally acceptable terminology which is also explained by the attached diagram.

A study of the problems associated with Dalangdian reservoir, China

There are over 2,300 lakes over 1 km2 in China (total area 80 000 km2). In addition there are approximately 87 000 reservoirs with a storage capacity of 413 billion m3. These form the main supply of drinking water as well as water for industrial and agricultural production and aquaculture. Because of a lack of understanding of the frailty of lake ecosystems and poor environmental awareness, human activities have greatly affected freshwater systems. This article focuses on the problems of one water supply reservoir, Dalangdian Reservoir, and considers options for improving its management. Dalangdian Reservoir is described and occurrence of algal genera given. The authors conclude with remarks on the future of the Dalangdian Reservoir.

Coleta seletiva e compostagem na Vila do Abraão (Ilha Grande, RJ): aspectos e recomendações

Muitos programas de coleta seletiva e Usinas de Triagem e Compostagem (UTC) brasileiras tem se mostrado problemáticos, ineficientes ou, até mesmo, inviáveis. Apesar disso, continua a ser uma solução visada por parte de órgãos gestores e da população. Observando que a coleta seletiva e a instalação e operação de UTC são peças importantes para a prática da reciclagem, dentro do contexto de Gerenciamento Integrado de Resíduos Sólidos (GIRS), verifica-se a necessidade de melhor entendimento dos problemas a elas associados para que haja um melhor planejamento e minimização destes problemas. O presente trabalho tem por objetivo principal a recomendação de diretrizes para um estudo de viabilidade e implantação de coleta seletiva e Unidade de Triagem e Compostagem na Vila do Abraão (Angra dos Reis, RJ), observando as características locais e as dificuldades normalmente existentes em programas de coleta seletiva e em operações de UTCs. A análise, que foi feita através de revisão bibliográfica de artigos científicos sobre estudos de casos brasileiros acerca de coleta seletiva, UTC e compostagem, mostrou que as principais dificuldades associadas a estes programas estão relacionadas: aos custos de operação e manutenção dos programas e das UTCs; às falhas administrativas e operacionais das UTCs; à capacitação inadequada dos trabalhadores; à falta de conscientização ambiental da população; ao desenvolvimento de soluções isoladas (fora do contexto de gerenciamento integrado) e que desconsideram os fatores locais. Também foi feito um levantamento das características locais da Vila através de observações in loco, entrevistas e trabalhos de campo. Sobre a Vila do Abraão constatou-se que ainda são necessários entendimentos entre os gestores locais (subprefeitura, Parque Estadual da Ilha Grande), a população e a municipalidade em Angra dos Reis, assim como, faz-se necessário um estudo mais aprofundado sobre a operação da UTC, incluindo aí as parcerias necessárias (cooperativas, catadores, prefeitura, ONGs etc) e sobre um programa de educação ambiental, para a efetiva participação da comunidade local. Além das recomendações feitas aos gestores locais, são indicados estudos que podem complementar o presente trabalho

A implantação da Coleta Seletiva Solidária em uma empresa pública de administração indireta de caldeiraria pesada do estado do Rio de Janeiro.

A crescente geração de resíduos e desperdício das repartições públicas, os custos de seu manejo e a necessidade de inclusão social dos catadores foram os propulsores para o modelo de Gerenciamento de Resíduos Sólidos Recicláveis (MGRSR) desenvolvido, visando à implementação da Coleta Seletiva Solidária em empresas e indústrias públicas. As perguntas que nortearam o desenvolvimento deste trabalho foram: Como o programa de coleta seletiva solidária impacta a gestão de uma empresa? Há dificuldades para o cumprimento do Decreto 5940/06? O MGRSR teve como base o modelo do PDCA (NBR 14001:2004), o Manual de Gerenciamento de Resíduos da FIRJAN, além dos requisitos legais que regulamentam o Gerenciamento de Resíduos e a Coleta Seletiva Solidária no Brasil. Foi adotado, como metodologia, o Estudo de caso em uma fábrica pública de Caldeiraria Pesada, por suas características de produção e grande geração de sucatas metálicas e o uso de mapas conceituais, desenvolvidos por meio da ferramenta IHMC Cmap Tools v.05.04.01. Os principais resultados da aplicação do modelo foram: elaboração de procedimentos internos; otimização da segregação dos resíduos com diminuição do percentual de resíduos perigosos gerados e aumento da taxa de reciclagem; sensibilização ambiental e a formalização de termos de doação com cooperativas/associações no período de 2009 a 2011. Porém, foram entraves: a ausência de área adequada ao armazenamento e triagem dos resíduos, de um sistema adequado de logística, de licenças dos galpões das cooperativas, a resistência à doação dos recicláveis, uma vez que a renda obtida com a sua venda estimada em R$300 mil reais/ano, deixaria de compor o orçamento da empresa e o fato do pesquisador ser também um dos atores no processo de implantação do programa. Recomendações foram feitas em análise crítica ao modelo sugerido: incluir na fase de planejamento a elaboração de projetos socioambientais às Cooperativas e a aprovação de verba específica para o Programa de Coleta Seletiva Solidária; criar programa de redução de resíduos; criar relatório para ser enviado ao Comitê Interministerial de Inclusão Social dos Catadores de Materiais Recicláveis e ao INEA/Gerência de Educação Ambiental com as sugestões de alteração do Decreto n 5940/06 e dos relatórios semestrais; e verificar a possibilidade de replicação do modelo MGRSR em outras organizações. Na conclusão, identificou-se que o MGRSR foi aplicável à empresa objeto de estudo e que o Programa de Coleta Seletiva Solidária permite sensibilização ambiental dos atores sociais envolvidos; inclusão social, melhoria da imagem da empresa, redução de resíduos gerados e desperdícios traduzidos em economia a médio e longo prazo, melhoria das articulações entre as diversas organizações públicas; aumento de trabalho e renda com melhoria das condições de saúde e trabalho do catador.
