    In the context of the Decade of Education for Sustainable Development, we believe that teachers of Natural Sciences may include, in their classes, discussions related to the causes and consequences of the environmental crisis. The consumption is one of the issues that can be addressed, because it has a direct relationship with environmental problems. With this article, we emphasize the importance of integrating the consumption theme in teaching natural science and present possibilities for discussions regarding its contemporary features and their consequences, in order to contribute to the realization of the assumption of  sustainable consumption in our societyNo contexto da Década da Educação para o Desenvolvimento Sustentável, consideramos que professores de Ciências Naturais podem inserir, nas suas aulas, discussões relacionadas às causas e às consequências da crise ambiental. O consumo é um dos temas que pode ser abordado, notadamente por ter relação direta com os problemas ambientais em vigência. Objetivamos com este artigo ressaltar a importância da inserção do tema consumo no ensino de ciências naturais e apresentar possibilidades de discussões, no que tange as suas características contemporâneas e suas consequências, na perspectiva de contribuir para a efetivação do pressuposto do consumo sustentável na nossa sociedade

    The society has been confronted with issues that involve interactions between science, technology and society (STS), which reveal social, economic, environmental, ethical implications, among others. The sustainability paradigm occupies a prominent position in this area. We understand that the STS guidelines are an important instrument for building the concept of sustainability in science education, whose perspectives consistent with the formation of citizens with environmental sensitivity-citizens who are able to analyze and evaluate critically issues related to the social, environmental and economic field, among other aspects. We propose, in this article, to discuss the possible links between the sustainability paradigm, the STS approach and the process of teaching and learning in science. This articulation certainly helps to think the implications of the current development model and the relationships STS, inserted, for example, on various issues, contexts, dimensions, knowledge and teaching strategies. Certainly, we must undertake the effort to approximate the natural and social fields, in the apprehension of the complex reality as it stands nowadaysA sociedade tem sido confrontada com questões que envolvem as interações entre Ciência, Tecnologia e Sociedade (CTS), as quais revelam implicações sociais, econômicas, ambientais, éticas, entre outras. E o paradigma da sustentabilidade ocupa posição destacada nesse âmbito. Entendemos que as orientações CTS constituem importante instrumento para a edificação da noção de sustentabilidade, no campo do ensino de ciências, cuja perspectiva insere-se na formação de cidadãos com sensibilidade socioambiental – cidadãos que possam analisar e avaliar criticamente as questões relacionadas aos campos social, ambiental, econômico, entre outros. Propomo-nos, neste artigo, a discutir as articulações possíveis entre o paradigma da sustentabilidade, o enfoque CTS e o processo de ensino e de aprendizagem em ciências. Essa articulação, certamente, contribui para pensar as implicações do atual modelo de desenvolvimento e as relações CTS inseridas, por exemplo, em vários temas, contextos, dimensões, saberes e estratégias de ensino. Certamente, temos que empreender esforços no sentido de aproximar o campo natural e o campo social, na apreensão da complexa realidade que hoje se apresenta

    O cenário vigente na nossa sociedade, de um modo geral, tem apontado para crescentes desigualdades sociais e econômicas, fundamentados no modelo de desenvolvimento produtivo de corte neoliberal (capitalismo), apresentando, inclusive, desdobramentos para o campo ambiental. Em realidade, a maioria das sociedades aderiu à luta competitiva pela existência, acredita no progresso como crescimento econômico e tecnológico, supervaloriza a individualidade em detrimento das possibilidades de interações humanas, da solidariedade, da cooperação e de tantas outras características que nos tornam humanos. Ao considerarmos esse contexto, damo-nos conta de que os aspectos relativos à justiça social e ambiental são subteorizados ou pouco valorizados na educação em ciências, em todos os seus níveis. E, propomo-nos, neste ensaio, refletir sobre importantes questões relativas à justiça social e ambiental, em suas inter-relações com a cidadania, a democracia e os valores éticos na formação de sociedades mais justas

    Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

    A new trend in terms of actions for the local development has been configured. These actions consider the territory and its actors. It is in this context that the inductions methodology of the Integrated and Sustainable Local Development (DLIS, from the portuguese Desenvolvimento Local Integrado e Sustentável) arises. This Program is a strategy of participatory induction for the development, which mobilizes communities resources, that in partnership with the State (in its three levels) and the market, reaches diagnostics and identify potential vocations, prepare integrated development plans, in the perspective of the subjects involvement as proponents and protagonists of a social action in their territories. With this study it was aimed to understand the multidimensionality of the DLIS process in the state of Roraima, and at the same time, looking for the causal link between the socio-economic trajectories (results) of DLIS and social capital. The survey is characterized as qualitative research. The case study method was applied, involving the municipalities of Rorainópolis, Uiramutã, Baliza and Pacaraima. It was adopted three dimensions analytical contextual, which are: conceptual, implementation and of impact. In the evaluation of social capital were considered as variables the participation, trust, cooperation and networks. During the data interpretation, the following approaches were employed: contextual analysis, descriptive analysis, differences in proportions analysis and correspondence analysis. The survey results showed that some concepts and categories employed by the Program, while important, have some failures. Two municipalities, Rorainópolis and Uiramutã, were considered as good results. This, because they combine a number of issues that expressed desirable conditions to turn the DLIS effective with its multiple dimensions. Moreover, the municipalities of Baliza and Pacaraima were classified as bad results municipalities. The results of the DLIS in Rorainópolis and Uiramutã are linked to the social capital (positive relation). Despite of the extensive literature that assigns the relevance of the social capital, it does not have, yet, satisfactory instruments to measure the social capital. In this context and in fact, the understanding of these results represents merely an approximation.CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorUma nova tendência em termos de ações para o desenvolvimento vem se configurando. Trata-se de ações que levam em conta o território e seus atores. Nesse âmbito, insere-se a metodologia de indução do Desenvolvimento Local Integrado e Sustentável (DLIS). Esse Programa de política pública se constitui uma estratégia participativa de indução do desenvolvimento, pela qual se mobilizam recursos das comunidades, que em parceria com o Estado (em seus três níveis) e o mercado, realizam diagnósticos, identificam potencialidades e vocações, elaboram planos integrados de desenvolvimento, na perspectiva de envolvimento dos sujeitos como proponentes e protagonistas da ação social em seus territórios. Com este trabalho, buscou-se compreender a multidimensionalidade do processo de DLIS, no estado de Roraima, procurando, ao mesmo tempo, o estabelecimento de um nexo causal entre as trajetórias sócio-econômicas (resultados) do DLIS e o capital social. A pesquisa se enquadrou na modalidade qualitativa. Adotou-se como estratégia metodológica o estudo de caso, envolvendo os municípios de Rorainópolis, Uiramutã, Baliza e Pacaraima. Três dimensões analítico-contextuais foram adotadas, quais sejam: conceitual, de implementação e de impacto. Na avaliação do capital social, as variáveis participação, confiança, cooperação e redes foram consideradas. Na interpretação dos dados, as seguintes abordagens foram utilizadas: análise contextual, análise descritiva, análise das diferenças de proporções e análise de correspondência. Os resultados da pesquisa revelaram que alguns conceitos e categorias adotados pelo Programa, embora relevantes, apresentam alguma ordem de problema. Dois municípios, Rorainópolis e Uiramutã, foram considerados municípios de bons resultados. Isso porque atenderam a um conjunto de questões que expressavam condições desejáveis para que o desenvolvimento local integrado e sustentável, em suas múltiplas dimensões, se efetivasse. Por seu turno, os municípios de Baliza e Pacaraima foram classificados como municípios de maus resultados. Os resultados do DLIS em Rorainópolis e Uiramutã estão associados ao capital social (relação positiva). A despeito da extensa literatura que trata da relevância desse tema, não se têm, ainda, instrumentos satisfatórios para medir capital social. Nesse contexto, entendese que estes resultados representam, de fato, uma aproximação
