Culture clash : artistic production and the school environment

Artists-in-schools programs involving contemporary art practices can be transformational for the participants when environmental considerations are integral to the planning and structure of the project and both the form and content of the program are reflected upon critically.

School and community partnerships in socially critical environmental education : research as environmental activism

Through a critical ethnography of a school and community, this study identifies and describes-in-action an approach to environmental education that supports the socially critical aspirations of many contemporary environmental education activists and examines its fate in the policy context of educational restructuring.  The study provides a critical analysis and exploration of environmental education and environmental activism within the context of social change.

Drip irrigation of treated municipal effluent in vineyards

Vine-row soil chemical and physical properties were significantly and detrimentally altered by drip irrigation of treated municipal effluent. Hydraulic gradients under the drip-emitter fostered strong chemical gradients and high variability of vine-row soil parameters, complicating soil management. Gypsum improves soil properties without impacting vine production when applied in small quantities.

Marine protected areas of the central Victoria bioregion

Along Victoria’s coastline there are 30 Marine Protected Areas (MPAs) that have been established to protect the state’s significant marine environmental and cultural values. These MPAs include 13 Marine National Parks (MNPs), 11 Marine Sanctuaries (MSs), 3 Marine and Coastal Parks, 2 Marine Parks, and a Marine Reserve, and together these account for 11.7% of the Victorian marine environment. The highly protected Marine National Park System, which is made up of the MNPs and MSs, covers 5.3% of Victorian waters and was proclaimed in November 2002. This system has been designed to be representative of the diversity of Victoria’s marine environment and aims to conserve and protect ecological processes, habitats, and associated flora and fauna. The Marine National Park System is spread across Victoria’s five marine bioregions with multiple MNPs and MSs in each bioregion, with the exception of Flinders bioregion which has one MNP. All MNPs and MSs are “no-take” areas and are managed under the National Parks Act (1975) - Schedules 7 and 8 respectively.

This report updates the first Marine Natural Values Study (Plummer et al. 2003) for the MPAs in the Central Victoria bioregion on the central coast of Victoria and is one of a series of five reports covering Victoria’s Marine National Park System. It uses the numerous monitoring and research programs that have increased our knowledge since declaration and aims to give a comprehensive overview of the important natural values of each MNP and MS.

Environmental assessment methods in Abu Dhabi

Abu Dhabi is one of the fastest developed cities in the region. On top of all the current and future environmental challenges, Abu Dhabi aims to be among the top governments in the world in sustainable development. Abu Dhabi plans to create an attractive, livable and sustainable managed urban environment in which all necessary services and infrastructure are provided in a sustainable and timely manner. Abu Dhabi is engaged in a difficult challenge to develop credible environmental indicators that would assess the ambitious environmental targets. The aim of those indicators is to provide reliable guidance to decision makers and the public concerning key factors that determine the state of urban environment and identify major areas for policy intervention. In order to ensure sustainable development in UAE in general, and of Abu Dhabi City in particular, relevant and contextual environmental indicators need to be carefully considered. These indicators provide a gauge at a national government scale of how close countries are to establish environmental policy goals. The environment indicators assist city decision-making in such areas as identification of significant environmental aspects and observation of environmental performance trends. Those can help to find ways of reducing environmental pollution and in improving eco-efficiency. This paper outlines recent strategies implemented in Abu Dhabi that aims to improve the sustainable performance of the city's built environment. The paper explores the variety of current and possible indicators at different levels and their roles in the development of the city.

A produção orgânica de citros no Vale do Rio Caí/RS

Há uma preocupação crescente sobre a necessidade de produção e consumo de alimentos mais saudáveis, sem uso de agrotóxicos nem fertilizantes químicos. Neste contexto se insere a prática da agricultura orgânica que, contudo, apresenta resultados ainda pouco avaliados. Assim, pretendeu-se, nesta pesquisa diagnosticar a produção orgânica na região citrícola do Vale do Rio Caí, no Rio Grande do Sul. Inicialmente foram selecionadas propriedades de oito agricultores, todas já convertidas ao sistema orgânico de produção há pelo menos cinco anos. Para tanto foram aplicadas entrevistas semi-estruturadas junto às unidades familiares, visando diagnosticar os aspectos sociais, econômicos e técnicoambientais. Os agricultores orgânicos mostram-se satisfeitos com o sistema orgânico de produção, que de maneira geral proporciona boas produtividades com custos de produção menores do que no sistema convencional de cultivo. Os agricultores que se dedicam ao sistema orgânico de produção revelam bom conhecimento sobre o meio ambiente, plantas, solos e processos agroecológicos, aspectos políticos, econômicos e sociais, adquiridos através da participação em cursos, palestras, congressos, dias de campo, treinamentos, e através das reuniões e assembléias da Cooperativa ECOCITRUS. A constante troca de experiências entre os agricultores orgânicos tem contribuído na melhoria da qualificação técnica dos produtores, além de melhor conscientizá-los nos aspectos políticos, econômicos e sociais. A participação dos produtores na ECOCITRUS tem proporcionado melhor organização dos mesmos, contribuindo na viabilização da produção orgânica, inclusive com vantagens econômicocomerciais, pela obtenção de insumos orgânicos, venda da produção e estímulo ao beneficiamento da produção, visando agregar renda à propriedade.

In the eye of the storm: exploring the introduction of environmental issues in the production function in Brazilian companies

This article aims to analyse the introduction of environmental issues in the context of the production function, which has been referred to as the organisational area to lead corporate environmental management. With that purpose, the theoretical references for corporate environmental management and the necessary alterations in production function have been organised to include environmental aspects, especially in terms of product and process development, quality management, and logistics. Considering that this research field still lacks empirical evidence for Brazilian companies, four case studies were conducted using companies located in the country. The environmental management maturity level of those companies tends to follow the rate with which the environmental issue is introduced in production sub-areas, especially in the product development process. However, in most cases we found that the companies had difficulties in structuring the insertion of the environmental dimension in logistics. The final notes point out the distance observed between what is recommended by international literature and the reality of Brazilian companies in the challenge of making the production function environmentally friendly.

Environmental education and the health risk question: how do we educate the educators working with this theme?

Our society is presently seeing a trend of continuous increase of risk with severe consequences, especially those linked to environmental aspects. It has obligated us to reflect on this production and its effects, either positive or negative, and, after a long reflection, to think about the adopted model of civilization and the possibilities of changing such a model. The educational institution is among the social departments responsible for this revision process, since it represents one possibility to promote a more critical vision from society, providing it with tools needed for a more responsible action. However, schools are dominated by a traditional work, which does not allow for enough and proper attention to these relevant and current questions, and which involve a critical analysis of the conceptions and values established by our civilization, resulting in the present patterns of science-technology-society relations and their influence on the environment and health. Several research works have indicated a diversity of barriers that obstruct this necessary change. Since formal education plays an important role in the education of society for this theme, in this paper the possibilities and difficulty dealing with this problem are discussed, focusing on the question of teacher education, based on investigations related to teacher education programs for environmental education. The data collected show the urgency for introducing this theme in teacher training programs, taking into account the fact that educators have their own conceptions, values and attitudes that should be considered in these programs.

Organotins: A review of their reproductive toxicity, biochemistry, and environmental fate

The review purposes are to (1) evaluate the experimental evidence for adverse effects on reproduction and metabolism and (2) identify the current knowledge of analytical procedures, biochemistry and environmental aspects relating to organotins. Organotins are pollutants that are used as biocides in antifouling paints. They produce endocrine-disrupting effects in mollusks, such as imposex. In rodents, organotin exposure induces developmental and reproductive toxicity as well as alteration of metabolic homeostasis through its action as an obesogen. The adverse effects that appear in rodents have raised concerns about organotins' potential health risk to humans in relation to organotin exposure. At present, triorganotin, such as tributyltin, have been demonstrated to produce imposex, and mammalian reproductive and metabolic toxicity. For most mammals, triorganotin exposure predominantly occurs through the ingestion, and this compound can cross the placenta. With these risks in mind, it is important to improve our knowledge of organotins' effects on environmental health. © 2012 Elsevier Inc.

Políticas públicas, corredores de exportação, modernização portuária, industrialização e impactos territoriais e ambientais no município de Barcarena, Pará

Este artigo discute as dinâmicas de aglomeração industrial, incremento e modernização portuária no município de Barcarena, Estado do Pará, Brasil. Especificamente, discute as causas estruturais que explicam estas dinâmicas, e as mudanças qualitativas e quantitativas locais, acerca dos aspectos espaciais, sociais, demográficos e ambien-tais. Diferentes momentos de produção e exportação de produtos minerais (caulim, bauxita e produtos originados dela – alumina, alumínio) na Amazônia Oriental Brasileira levam a instalação, consolidação e expansão de um distrito industrial e portuário em Barcarena. Na atual década, Barcarena integra um corredor de exportação diretamente ligado a eixos ou sistemas produtivos nacionais e globais. Contudo, as dinâmicas que sustentam este crescimento econômico não apontam para perspectivas de que a produção conduza ao enraizamento social do desenvolvimento, ao estabelecimento de vantagens competitivas que tenham uma base sistêmica; tampouco contribui para a reversão dos impactos sociais e ambientais.
