Journal of Cleaner Production, nº 16, p. 639-645 ; Environmental Impact Assessment (EIA) education has been a reality for years in many graduate and undergraduate programs worldwide. As EIA has grown as a widely accepted environmental policy tool, several professions have tried to incorporate these skills into their academic training. The main aim of this research was to assess the Portuguese profile of EIA education, measuring the degree of EIA integration in graduate and undergraduate programs. This paper intends to contribute to an understanding of the key factors related to EIA education. A national survey was conducted to obtain data on EIA education programs. More recently, many other programs, both graduate and undergraduate, have established EIA courses. New knowledge, practices, legislation and public policies are fundamental drivers of the application of EIA, which will probably continue to expand to more undergraduate and graduate programs. The association of EIA with other environmental management tools, such as environmental management systems or environmental performance evaluation, and sustainable development initiatives will be a priority challenge for all who are engaged in this domain.

Atualmente não é mais possível compreender o ensino centrado apenas no professor, antes considerado o único detentor do conhecimento. O processo de ensino-aprendizagem deve ser algo dinâmico que estrutura, e é estruturado de acordo com as relações forjadas em seu desenrolar. Assim, ferramentas como os softwares de modelagem surgem para otimizar e auxiliar nesse processo. Nesta perspectiva, o presente trabalho busca refletir sobre as mudanças conjunturais que levam os professores a adotar novas posturas para um melhor desenvolvimento do processo de ensino-aprendizagem. Em decorrência destas transformações, os docentes têm adotado novas formas de ensinar, que abrem espaço ao uso das novas tecnologias, cujas contribuições são inegáveis, especialmente, no ensino de Química. No entanto, em face da falta de preparo, do medo de mudanças e do modo acelerado como essas mudanças têm ocorrido, os professores da referida disciplina têm construído uma representação social acerca do uso das novas tecnologias, notadamente, dos softwares de modelagem, que tem tornado lento e confuso o processo de informatização do ensino de química. Neste sentido, cremos na pertinência deste trabalho, pois, essa discussão pode nos fazer compreender em que medida os professores de Química podem utilizar criticamente as novas tecnologias, aprimorando a sua prática.

Journal of Cleaner Production, nº 17, p. 36-52 ; The environmental performance evaluation (EPE) of organizations is becoming an autonomous management tool. The main goal of this research was to assess the state of EPE practice in the Portuguese defence sector, as a particular part of public services. A questionnaire survey was conducted involving all Portuguese military units that have a person in charge of environmental issues. The questionnaire was designed to assess: (i) the importance and drivers of EPE; (ii) the ISO 14031 knowledge and implementation; (iii) the knowledge and use of environmental indicators; (iv) the optimal format for indicators; and (v) the advantages and drawbacks of using environmental indicators. Despite various initiatives driving environmental practices in public organizations, most of that experience is only centred on an environmental management system, and EPE is quite a new issue. Nevertheless, general environmental performance evaluation is a growing reality and one in which Portuguese military units are taking an increasing interest. Overall respondents agree on the importance of measuring and communicating environmental performance related to their main missions and activities. The main drivers for EPE in military units are the prevention of health risks and compliance with regulations. However, to date, ISO 14031 and environmental performance indicators are almost unknown in the respondent military units. Among the three military branches, the Navy revealed the worst environmental performance evaluation knowledge, awareness and practice.

Progress in Industrial Ecology, An International Journal, nº 4(5), p. 363-381 ; Public institutions are beginning to realise that they must shift their management towards sustainability. Thus, public sector, including defence services, environmental performance evaluation is a growing reality. The main objective of this research was to assess the environmental pressures and impacts profile of the Portuguese defence sector. A questionnaire survey was conducted involving all Portuguese military units that have a person in charge of environmental issues. Respondents generally reported that the majority of their activities have few serious environmental problems. These results could show the respondents' general perception of the increasing implementation of environmental management practices in military units and probably some lack of knowledge, but also a standard based on compliance with regulations. Many environmental pressures in the Portuguese military are related to primary environmental problems, such as water supply, wastewater and solid waste, showing that the integration of environmental awareness and practices into the Portuguese military is quite new.

Objetivo: Investigar se uma empresa que atua no contexto de uma rede interorganizacional está preparada para o desenvolvimento de Capacidades Dinâmicas (CDs) que contribuem para o desenvolvimento de atividades de Inovação Orientadas para a Sustentabilidade (do inglês Sustainability-oriented Innovation – SOI).
Método: O trabalho emprega o método de estudo de caso único com uma abordagem predominantemente qualitativa em uma empresa que atua no setor do agronegócio. O principal instrumento de coleta de dados foi a entrevista semiestruturada realizada com gestores. Para a análise dos dados foi utilizada a técnica de análise de conteúdo.
Originalidade/valor: A pesquisa integra os conceitos de CDs, redes interorganizacionais e atividades de SOI (otimização operacional, transformação organizacional e construção de sistemas).
Resultados: Evidenciou-se que os fatores de prontidão "relações interorganizacionais" e "tecnologias para SOI", associados respectivamente à capacidade de colaboração e capacidade tecnológica são os mais influentes nas atividades de otimização operacional, transformação organizacional e construção de sistemas.
Contribuições/Implicações: A pesquisa propõe novas perspectivas de análises das atividades de SOI e identifica fatores e CDs que podem ser potencializados por outras empresas que tenham o interesse de aprimorar seus relacionamentos colaborativos e suas inovações com foco na sustentabilidade.

Proceedings of the First International Conference on Coastal Conservation and Management in the Atlantic and Mediterranean, p. 91-98 ; Over the last two decades, the Tróia peninsula (SW coast of Portugal) has been designated by the Portuguese authorities both as a protected area and as an area of tourism development. The private investor that took over the tourism developments in Tróia asked the Institute of Marine Research (IMAR) to undertake an SEA, to help frame the design and management of the future resort. SEA results were changed by local/central government decisions, granting "more" than stakeholder/owner's proposal, in terms of loads and densities. This process, as well as the main characteristics and results of the SEA, are presented and discussed.

The use of pre-harvest desiccants contributes to reducing the exposure of seeds to unfavorable climatic conditions, reducing environmental interference in their quality. But this use must be done in a way that affects, as little as possible, the agronomic behavior of the plants. The objective of this study was to evaluate the action of paraquat desiccation, applied at different reproductive stages, on the agronomic behavior of sunflower plants and the quality of its seeds. The experimental design used was randomized blocks in a factorial scheme with three repetitions. The herbicide Paraquat (2,0 L ha-1) was applied in the phases R7, R8 and R9 to plants of the cultivars BRS 323, Aguará 4 and M734. The characters evaluated were achene yield, oil content, weight of one thousand achenes, and germination. The most adequate reproductive stage for desiccation of sunflower plants with Paraquat was the R8 stage, obtaining the highest yield of achenes, oil content and weight of one thousand achenes. At this reproductive stage, there was no difference between the average germination values of sunflower achenes obtained with or without the application of the desiccant.
