Sustainable agriculture

This paper provides an overview of concepts of sustainable agriculture and possible methods of attaining sustainability of agricultural yields and production. Reasons are given as to why modern industrialised agriculture might be less sustainable in terms of yields than traditional agriculture. The question of whether organic agriculture is likely to be more sustainable than non-organic agriculture is considered as well as organic agriculture’s likely impact on wild biodiversity. The impact of the development of agriculture on wild biodiversity is assessed because some environmentalists see the conservation of wild biodiversity as an important ingredient of sustainable development. However, there is a policy conflict between conservationist groups. Some see intensive agriculture (including silviculture) as favourable to the conservation of wild biodiversity whereas others oppose such production methods as being unfavourable to wild biodiversity conservation. Reasons why modern industrialised agricultural systems are so widely adopted (and continue to be adopted) despite their apparent lack of sustainability are suggested. Market systems may tend to lock producers into unsustainable production methods.

PRECARIEDADE DOS PROFESSORES UNIVERSITÁRIOS

São tantos os estudos que demonstram que é pela qualidade da educação das pessoas que depende o grau de desenvolvimento dum dado país, que não caberia aqui citá-los um a um. Os estudos nacionais e internacionais são unânimes: investir na educação é investir no futuro honesto da Humanidade. É investir num desenvolvimento sustentável. É investir no ser humano e numa justiça verdadeira, concreta e sensível. E se investir na saúde é prioritário em absoluto, investir na educação também. § There are so many studies that show that it is the quality of education of the people who depend on the degree of development of a given country, that would not fit here quote them one by one. National and international studies are unanimous: investing in education is investing in the future of honest humanity. It is investing in sustainable development. It is investing in people and in true justice, concrete and sensitive. And investing in health is a priority at all, invest in education as well.

Integration of management systems: towards a sustained success and development of organizations

Effective environmental management within companies, integrated with other management areas like quality and occupational health and safety, is nowadays assumed to be a strategic way to implement and improve lean and cleaner production. Also, sustainable development (SD) and business sustainability can be achieved through a better coordinated management of processes versus associated resources. This paper presents an in depth discussion regarding the promotion of integrated management systems, their benefits and major contribution towards the sustainable development of cleaner production related features. It addresses issues regarding the contributions resulting from the integration of standardized Management System (MS) from both internal and external perspectives. Complementing the overall review of aspects to the development of integrated management systems a survey was conducted in order to better understand the relevance of the identified success factors. The main findings in this paper are as follows: a contextualization model of sustainable development and integrated management systems considering the Triple Bottom Line: economic, social and environmental; and, a method and associated model to support the development of integrated management systems as well as general guidelines to support integration. It can be concluded that a proactive approach and commitment to cleaner production, supported by an integrated management system, brings relevant savings for organizations as well as providing value to the relevant interested parties.

The role of teaching decision analysis for sustainability in engeneering schools

This paper addresses the role that decision analysis plays in helping engineers to gain a greater understanding of the problems they face. The need of structured decision analysis is highlighted as well as the use of multiple criteria decision analysis to tackle sustainability issues with emphasis in the use of MACBETH approach. Some insights from a Portuguese Summer Course on engineering for sustainable development are presented namely the students 'and teacher perceptions about the module of decision analysis for sustainability.

Conceiving modern engineers within the framework of the sustainability action plan (PASUS) of ISEP: sustainability matters!

Engineering education practices have evolved not only due to the natural changes in the contents of the curricula and skills but also, and more recently, due to the requirements imposed by the Bologna revision process. In addition, industry is becoming more demanding, as society is becoming more and more aware of the global needs and consequences of industrial practices. Under this scope, higher education needs not only to follow but also to lead these trends. Therefore, the School of Engineering of the Polytechnic Institute of Porto (ISEP), a Global Reporting Initiative (GRI) training partner in Portugal, prepared and presented its Sustainability Action Plan (PASUS), with the main objective of creating a new kind of engineers, with Sustainable Development at the core of their graduation and MsC degrees. In this paper, the main strategies and activities of the referred plan along with the strategic approach, which guided its development and implementation, will be presented in detail. Additionally, a reflection about the above mentioned bridge between concept and application will be established and justified, in the framework of the action plan. Although in most of the situations, there was no prior discussion or specific request, many of the graduation and post-graduation programmes offered by ISEP already include courses that attend to PASUS philosophy. As a consequence, the number of Master thesis, Graduation projects and R&D projects that address sustainability problems has grown substantially, a proof that for ISEP community, sustainability really matters!

Challenges in the creation and development of a mathematics MOOC

The fast development of distance learning tools such as Open Educational Resources (OER) and Massive Open Online Courses (MOOC or MOOCs) are indicators of a shift in the way in which digital teaching and learning are understood. MOOC are a new style of online classes that allow any person with web access, anywhere, usually free of charge, to participate through video lectures, computer graded tests and discussion forums. They have been capturing the attention of many higher education institutions around the world. This paper will give us an overview of the “Introduction to Differential Calculus” a MOOC Project, created by an engaged volunteer team of Mathematics lecturers from four schools of the Polytechnic Institute of Oporto (IPP). The MOOC theories and their popularity are presented and complemented by a discussion of some MOOC definitions and their inherent advantages and disadvantages. It will also explore what MOOC mean for Mathematics education. The Project development is revealed by focusing on used MOOC structure, as well as the quite a lot of types of course materials produced. It ends with a presentation of a short discussion about problems and challenges met throughout the development of the project. It is also our goal to contribute for a change in the way teaching and learning Mathematics is seen and practiced nowadays, trying to make education more accessible to as many people as possible and increase our institution (IPP) recognition.

Learning sustainability by developing a solar dryer for microalgae retrieval

The development of nations depends on energy consumption, which is generally based on fossil fuels. This dependency produces irreversible and dramatic effects on the environment, e.g. large greenhouse gas emissions, which in turn cause global warming and climate changes, responsible for the rise of the sea level, floods, and other extreme weather events. Transportation is one of the main uses of energy, and its excessive fossil fuel dependency is driving the search for alternative and sustainable sources of energy such as microalgae, from which biodiesel, among other useful compounds, can be obtained. The process includes harvesting and drying, two energy consuming steps, which are, therefore, expensive and unsustainable. The goal of this EPS@ISEP Spring 2013 project was to develop a solar microalgae dryer for the microalgae laboratory of ISEP. A multinational team of five students from distinct fields of study was responsible for designing and building the solar microalgae dryer prototype. The prototype includes a control system to ensure that the microalgae are not destroyed during the drying process. The solar microalgae dryer works as a distiller, extracting the excess water from the microalgae suspension. This paper details the design steps, the building technologies, the ethical and sustainable concerns and compares the prototype with existing solutions. The proposed sustainable microalgae drying process is competitive as far as energy usage is concerned. Finally, the project contributed to increase the deontological ethics, social compromise skills and sustainable development awareness of the students.

Construção de um dispositivo de autoavaliação com a colaboração dos docentes

Na atualidade, face à emergência de políticas educacionais influenciadas pela globalização, a avaliação das instituições escolares tem vindo a constituir-se como um instrumento para regular, garantir e acompanhar a melhoria da qualidade nos sistemas de ensino. A Lei nº31/2002 de 20 de dezembro implicou nas escolas o desenvolvimento de dispositivos, instrumentos e processos diversos de avaliação tendo como um dos seus objetivos a promoção da melhoria de qualidade do sistema educativo. Não é qualquer forma ou modalidade de avaliação institucional e de autoavaliação que pode responder à multidimensionalidade e complexidade das escolas públicas enquanto organizações educativas específicas. Pelo facto de não existirem escolas iguais, a avaliação da escola deverá ser diferenciada e ajustada às realidades organizacionais para constituir um efetivo instrumento de desenvolvimento. O estudo empírico realizado no agrupamento X pretendeu recolher as perceções dos docentes do agrupamento em relação aos mecanismos de autoavaliação para a posterior elaboração de um dispositivo de autoavaliação. Este estudo permitiu reconhecer a importância atribuída aos processos de autoavaliação na promoção da melhoria da organização e do sucesso educativo dos alunos, bem como os constrangimentos associados a estes processos, sendo também apresentadas propostas para que este instrumento seja eficaz. Os resultados deste estudo foram as linhas orientadoras para a construção de um dispositivo de autoavaliação para o agrupamento X com a colaboração dos docentes, desenvolvendo um plano de ação com atividades definidas. Espera-se dar um contributo para implementar mudanças significativas, com vista à promoção de uma cultura de autorreflexão, de autoavaliação e de desenvolvimento sustentado da escola.

Contributo das organizações do terceiro setor no desenvolvimento dos países de píngua pficial portuguesa

O empreendedorismo social é um campo que tem vindo a ganhar uma importância crescente nas sociedades atuais, sendo reconhecido como uma ferramenta útil na promoção do desenvolvimento sustentável. Como se trata de um campo emergente, apresenta-se ainda pouco explorado. Em Cabo Verde não existem ainda estudos sobre o tema, embora existam já algumas iniciativas de empreendedorismo social. A investigação foi desenvolvida de forma a responder ao objetivo de se conhecer qual o contributo que as Organizações Não Governamentais para o Desenvolvimento (ONGD) portuguesas têm dado para a sedimentação do empreendedorismo social em Cabo Verde. Assim, procurou-se apurar e analisar as ONGD que desenvolvem projetos em Cabo Verde, as áreas em que estas atuam para promoverem o desenvolvimento economico-social, os meios de financiamentos a que recorrem, as dificuldades encontradas no desenvolvimento das suas atividades, bem como compreender a razão que levou a que Cabo Verde fosse beneficiado com as ações dessas ONGD. Para conseguir atingir estas metas recorreu-se à metodologia qualitativa onde se fez uma análise exploratória e descritiva. A técnica utilizada para a recolha da informação primária foi a entrevista dirigida aos responsáveis de seis ONGD portuguesas que atuam em Cabo Verde, nomeadamente a Associação para a Cooperação Entre os Povos, a Associação de Defesa do Património de Mértola, Instituto Marquês de Valle Flôr, Meninos do Mundo, Terras Dentro e a Associação Raia Histórica. Os resultados deste estudo permitiram identificar que as ONGD portuguesas agem impulsionando o empreendedorismo social em Cabo Verde através da promoção do desenvolvimento integrado e sustentável, apoiado em parcerias estabelecidas com outras organizações locais caboverdeanas. Estes parceiros são atores chave que estão no terreno e possuem o conhecimento da realidade do país. Cabo Verde foi beneficiado pelos projetos por pertencer aos Países Africanos de Língua Oficial Portuguesa e/ou à Comunidade dos Países de Língua Portuguesa. Na obtenção de recursos, a maioria das ONGD portuguesas recorre a recursos em espécie e a voluntários portugueses, desempenhando estes o papel de formadores. A geração de valor social por parte destas entidades é feita muitas vezes de uma forma indireta, através da criação de valor económico que depois se repercute em valor social. Este valor social resulta da sua atuação em várias áreas como a saúde e segurança alimentar, desenvolvimento rural, meio ambiente, educação e formação profissional, emprego, economia alternativa ou microcrédito, pobreza e exclusão social, ambiente, habitação, promoção social e do turismo, capacitação e reforço institucional e coerência das políticas públicas para o desenvolvimento. Sendo Cabo Verde um arquipélago, as principais dificuldades encontradas pelas ONGD na sua atuação prende-se com a acessibilidade às ilhas devido à falta de transportes e meios de comunicação.
