- Application of microbial Inoculants as a sustainable practice for the production of grain legumes under water stressPublication . Carvalho, Patrícia; Marques, Sonya; Nunes, Mafalda; Marques, Guilhermina; Oliveira, Rui S.Grain legumes contain high level of protein and adequate proportions of carbohydrates and oil, making them valuable as human food. Unlike protein products of animal origin, legumes contain much less fat, which makes them healthier. The nutritional value of legumes has been associated with reduction of incidence of chronic diseases such as cancer, type-2 diabetes and heart disease. Arbuscular mycorrhizal fungi (AMF) and nitrogen fixing bacteria (NFB) are beneficial soil microorganisms that can improve plant nutrition and increase drought tolerance.
- Arbuscular mycorrhizal fungi are more efficient than chemical fertilisers in the production of essential oils of common thyme (Thymus vulgaris )Publication . Oliveira, Rui S.; Moreira, Vanessa; Nunes, Mafalda; Rocha, Inês; Carvalho, M. Fátima; Vosátka, Miroslav; Cavaleiro, Carlos; Salgueiro, Lígia; Freitas, HelenaCommon thyme is an aromatic plant with medicinal, cosmetics and culinary uses. Due to its antimicrobial, antioxidant/antiradical and antitumor activity the essential oils of common thyme are in great demand (Nikolić et al., 2014). A significant part of the production of aromatic plants relies on the use of chemical fertilisers, which when applied in large scale can have significant environmental consequences (Malik et al., 2011). Arbuscular mycorrhizal fungi (AMF) are a group of soil microorganisms that forms mutualistic symbioses that can benefit plants by improving the uptake of mineral nutrients, mineralising organic nutrients and conferring drought resistance (Oliveira et al., 2005).AMF have the potential to be inoculatedin the production of common thyme as an ecotechnological tool to reduce the input of chemicals fertilisers.
- Assessment of students’ attitudes and environmental behavior at School of Allied Health Sciences of Polytechnic Institute of PortoPublication . Nunes, Mafalda; Aguiar, MafaldaIn recent decades, the sustainability in higher education institutions has become an important issue for these institutions, as they realised their impacts in the environment and became more aware of their responsibilities to the society. Sustainability also presents an opportunity to promote new approaches in education such as problem based learning, more interdisciplinary and applied learning (Corcoran et al., 2004). As one of the key elements in these institutions, students play an important role, and their attitudes and environmental behaviour have a strong impact in the sustainability of the institutions and, as stated by Zsóka et al. (2013),students who behave in a consistently pro-environmental manner are drivers of a more sustainable future. It is crucial to know the students attitudes and environmental behaviour in order to promote, for example, effective environmental education.
- Carbon footprint of the School of Allied Health Technologies of Polytechnic Institute of PortoPublication . Frutuoso, Liliana; Ribeiro, Clara; Nunes, MafaldaHigher education institutions have increased their responsibilities for the reduction of greenhouse gas emissions (GHG) in order to contribute to a more sustainable development. The School of Allied Health Technologies is a good example of an institution that has environmental concerns and has been developing initiatives and commitments for a more sustainable environmental future. The calculation of the carbon footprint of this institution is another step towards this commitment. The carbon footprint can be defined as a measure of the GHG that are directly and indirectly caused by an activity, expressed in carbon dioxide equivalents (CO2-eq).
- Ecotoxicological evaluation of Pentachlorophenol in Avena sativa L. e Glycine max L.Publication . Pina, Ana; Nunes, Mafalda; Barros, PiedadePentachlorophenol (PCP) is the largest chlorinated compound from chlorophenols family and it is included in the list of priority pollutants from the US Environmental Protection Agency (EPA) and the European Union, due to its persistence and high toxicity. It was used mainly as a wood preservative; in fungicidal and insecticidal solutions and for incorporation into other pesticide products.
- Galardão Internacional Green Key em estabelecimentos turísticos: fundamentos e avaliação do grau de aplicação na Região Norte de PortugalPublication . Vieira Da Silva, Manuela; Fontes, Bárbara; Nunes, MafaldaTurismo assume um papel cada vez mais importante quer ao nível económico, ambiental, cultural e social e o seu crescimento nos últimos anos tem sido bastante significativo tornando-o um “motor” para o desenvolvimento Mundial. Apesar dos aspetos positivos, o turismo provoca impactos negativos com o seu aumento, nomeadamente ao nível ambiental. Como tal torna-se cada vez mais importante a consciencialização de um turismo sustentável. Em Portugal como forma a promover o turismo sustentável existe o programa Green Key (GK), um galardão internacional que dá reconhecimento a alojamentos turísticos e restaurantes pelas boas práticas ambientais e promoção para a sustentabilidade.
- Improved grain yield of cowpea (Vigna unguiculata) under water deficit after inoculation with Bradyrhizobium elkanii and Rhizophagus irregularisPublication . Oliveira, Rui S.; Carvalho, Patricia; Marques, Guilhermina; Ferreira, Luís; Pereira, Sandra; Nunes, Mafalda; Rocha, Inês; Ma, Ying; Carvalho, Maria F.; Vosátka, Miroslav; Freitas, HelenaCowpea (Vigna unguiculata (L.) Walp.), a plant broadly cultivated for human consumption and animal feed, is among the most nutritious grain legumes. Most of the areas where cowpea is grown are drought-prone, and there is a need to address this issue, with water scarcity becoming a major concern in agriculture. Cowpea is known to form mutualistic associations with nitrogen-fixing (NF) bacteria and arbuscular mycorrhizal (AM) fungi. These beneficial soil microorganisms have the capacity to benefit plants by reducing the effects of environmental stresses, including drought. Our aim was to study the effect of inoculation with Bradyrhizobium elkanii and Rhizophagus irregularis on the growth and grain yield of cowpea under water-deficit conditions. Under moderate water deficit, grain yield was increased by 63%, 55% and 84% in plants inoculated with B. elkanii, R. irregularis and B. elkanii R. irregularis, respectively. Under severe water deficit, inoculation with B. elkanii and B. elkanii R. irregularis resulted in grain-yield enhancement of 45% and 42%, respectively. The use of cowpea inoculated with NF bacteria and AM fungi has great potential for sustainable agricultural production under drought conditions.
- Increased protein content of chickpea (Cicer arietinum L.) inoculated with arbuscular mycorrhizal fungi and nitrogen-fixing bacteria under water deficit conditionsPublication . Oliveira, Rui S.; Carvalho, Patrícia; Marques, Guilhermina; Ferreira, Luís; Nunes, Mafalda; Rocha, Inês; Ma, Ying; Carvalho, Maria F; Vosátka, Miroslav; Freitas, HelenaChickpea (Cicer arietinum L.) is a widely cropped pulse and an important source of proteins for humans. In Mediterranean regions it is predicted that drought will reduce soil moisture and become a major issue in agricultural practice. Nitrogen (N)-fixing bacteria and arbuscular mycorrhizal (AM) fungi have the potential to improve plant growth and drought tolerance. The aim of the study was to assess the effects of N-fixing bacteria and AM fungi on the growth, grain yield and protein content of chickpea under water deficit.
- Modelo pedagógico Problem Based Learning aplicado na licenciatura em Saúde AmbientalPublication . Rodrigues, Matilde A.; Nunes, Mafalda; Freitas, Marisa; Santos, Joana; Silva, Manuela V.No ano letivo 2017/18 iniciou-se o processo de transição do plano de estudos do curso de Licenciatura em Saúde Ambiental, na Escola Superior de Saúde do Instituto Politécnico do Porto. A nova estrutura curricular do curso assenta no modelo pedagógico Problem Based Learning (PBL). Este modelo é muitas vezes definido em oposição às abordagens ditas como “tradicionais”. Um dos pontos mais diferenciadores é a sua interdisciplinaridade, a qual se encontra refletida na estrutura curricular do curso. A substituição do conhecimento fragmentado, apresentado nos modelos tradicionais em diferentes Unidades Curriculares (UC), pelo estudo de problemas reais em Saúde Ambiental que permitem envolver e relacionar várias áreas de conhecimento, promove não só uma melhor integração dos conteúdos curriculares, mas também potencia a aprendizagem, de uma forma contextual. Neste modelo pedagógico o docente deixa de ser visto como um meio para expor a matéria, passando a ser considerado pelo estudante como um especialista com quem poderá esclarecer as suas questões ao longo das sessões de recurso (equivalente às aulas teóricas). Adicionalmente, existe a necessidade da figura de um tutor, o qual acompanhará o grupo ao longo do estudo do problema nas sessões de orientação tutorial. Este trabalho em grupo promove o desenvolvimento de competências transversais. Foi realizada uma análise comparativa do desempenho dos estudantes entre os dois planos de estudos. Numa primeira fase, foram determinadas as notas equivalentes às novas UC dos 1º e 2º anos considerando a classificação obtida pelos estudantes em 16/17 e de acordo com o plano de acreditação do ciclo de estudos. Posteriormente, estes resultados foram comparados com as notas obtidas pelos estudantes nas novas UC em 2017/18. Os dados denotaram uma melhoria nos resultados de aprendizagem, enfatizando a pertinência do PBL na Licenciatura em Saúde Ambiental.
