- Risk Assessment for Water Reuse in Irrigating Green Areas on a University CampusPublication . Leite dos Santos, Lenise Maria; Ferreira, José; Ferreira Silva, Maria Elisabete; Lopes Brás, Isabel Paula; Berardi, U.; António, J.; SimõesThe increasing scarcity of water resources, exacerbated by climate change, calls for more sustainable and innovative approaches to water management. This study examines the feasibility and benefits of using Water for Reuse (WfR) for irrigation at the Polytechnic Institute of Viseu campus in Portugal. By using WfR, the university aims to reduce its reliance on potable water, promote sustainability, and enhance the resilience of its landscape management practices. However, assessing potential risks is crucial. Risks associated with the WfR from the Viseu Sul Wastewater Treatment Plant (WWTP) for green space irrigation on campus were evaluated, focusing on public health and water resource impacts. A semi-quantitative risk assessment methodology was applied, analysing microbiological, chemical, and physical parameters to ensure the treated water meets safety standards for its intended use. Three receptor groups were considered: maintenance workers, students/faculty, and visitors. Results showed the feasibility of producing and using WfR for irrigation, with the overall risk being below 3, considered negligible. The global public health risk was 0.72, with maintenance workers having the highest individual risk (0.75). The global risk for water resources was 2.30 for nitrogen and phosphorus, and 0.8 for microbiological risks. All risks were considered insignificant, making the use of WfR a viable and safe solution for sustainable water management.
- Biopreparados agroecológicos como solução biológicaPublication . Simões, Joana; de Vasconcelos Teixeira Aguiar da Costa, Daniela; Costa, Cristina Amaro daNa sociedade atual, a sustentabilidade ambiental e social é uma preocupação crescente, em particular na produção de alimentos que se traduz na crescente procura por produtos seguros para os ecossistemas e para o consumidor final. A utilização de biopreparados, com base na (re)utilização de recursos naturais existentes na exploração, é uma parte integrante de sistemas produção agroecológicos. Estudaram se sete biopreparados agroecológicos no projeto RESTORE - biopReparados Em SisTemas prOdução agRoEcológicos [projeto UIDB/00681/2020] – vinagre de figo-da-índia, vinagre de beldroega, sumo fermentado de laranja, extrato de alho, infusão de urtiga, decocção de cavalinha e biopreparado de alho e malagueta. O trabalho consistiu em: aplicação de inquérito aos agricultores sobre biopreparados utilizados; seleção e produção, análise físico-química e microbiológica e avaliação de efeitos in vivo de biopreparados. Foram realizados 17 inquéritos a produtores, na região Centro. Os biopreparados foram selecionados a partir da informação dos agricultores. Em laboratório, procedeu-se à quantificação de compostos fenólicos totais, análise da capacidade antioxidante e a da inibição de atividade microbiana, em bactérias e fungos, em três momentos temporais diferentes e com base no tipo de conservação estabelecida: logo após a preparação do biopreparado; três e seis meses após a conservação em fresco e seis meses após conservação por congelação. Os ensaios de campo foram realizados em viveiros de alface, em estufa, desde a sementeira até à transplantação. O sumo fermentado de laranja e os vinagres apresentam os melhores resultados em composição fenólica e capacidade antioxidante. Em termos de inibição de atividade microbiológica, o biopreparado de alho e malagueta é o que demonstra uma inibição mais consistente. A decocção de cavalinha demonstra apresentar melhores resultados enquanto bioestimulante no cultivo de alface. É essencial dar continuidade a estudos de avaliação dos efeitos dos biopreparados para melhorar o conhecimento sobre os mesmos e os seus efeitos, bem como para fundamentar uma tomada de decisão mais adequada.
- Consumer Perspectives Towards Edible Insects in a Western CountryPublication . de Pinho Ferreira Guiné, Raquel; Florença, Sofia de Guiné e; Ferreira, Manuela; Margarida Campos, Sofia; Paula Pereira de Oliveira Cardoso, Ana; Justin A. DanielsThis book includes eight chapters that detail recent advancements in environmental research. In Chapter 1, a bibliometric analysis of scholarly works published from 2014 to 2024 examines the relationship between sustainability and organizational justice in Asian higher education. In Chapter 2, the authors examine how seaweed promotes sustainable development and the blue economy and discuss how seaweed helps with food scarcity and environmental degradation. Chapter 3 focuses on the relationship between the microbiome and human health, pathologies and therapeutics of microbes, their contribution towards the environment, their role in modern agriculture and food security, advancements in technologies to study, and ethical and biosafety concerns regarding the handling of microbes. The study in Chapter 4 addresses the urgent issue of wastewater treatment and public water supply in relation to antibiotic resistance. The cost of producing biodiesel from waste vegetable oils was conducted in Chapter 5, along with an evaluation of the economic gains achievable through blending biodiesel with conventional diesel. Chapter 6 addresses issues related to the environment and sustainability and presents and discusses the findings of a study conducted in Portugal as part of the Edible Insects as Sustainable Food (EISuFood) initiative. In chapter 7, the authors address the three levels of grey water management implementation—decentralized, semi-centralized, and centralized—at the individual household, cluster, and village levels, as well as case studies. In the final chapter, the author investigates the vertical wind variability in the vicinity of tropopause.
- Risk assessment of reusing treated water from the Viseu Sul WWTP for irrigation and similar usesPublication . Santos, Lenise; Ferreira, José; Silva, Maria; Simões, Luis; Ferreira, Miguel; Brás, IsabelDue to the growing water scarcity, the reuse of treated wastewater arises as a possibility for sustainable water management. However, it is necessary to evaluate the possible risks associated with its activity. This study aims to develop a risk assessment of water for reuse, in terms of public health and water resources, for production and internal use by the Viseu Sul Wastewater Treatment Plant (WWTP) and external use in irrigation of green spaces in Viseu. The methodology used was a semi-quantitative risk assessment. The results demonstrated the viability of the production and use of Reused Water by the Viseu Sul WWTP, with an overall risk to public health of 0.68, and for use in irrigating green spaces in Viseu, with an overall risk of 0.75. The overall risk to water resources was 2.33 for nitrogen and phosphorus and 0.78 for E. coli. All risks were considered insignificant, considering the criteria defined by the method. Based on the information presented, it can be inferred that the use of treated wastewater to meet Viseu's water needs is a viable option.

- A importância crescente dos produtos agrícolas e agroalimentares locais: os efeitos da pandemia covid-19 nos circuitos curtos de proximidadePublication . Pato, Maria LúciaA crescente oferta de produtos agrícolas e agroalimentares, largamente disponíveis nas grandes superfícies de distribuição (híper e supermercados), a que se junta as mudanças operadas nos próprios ritmos de vida das pessoas, tem alterado drasticamente os hábitos de alimentação, sobretudo dos meios urbanos. Questões como a origem, a qualidade e segurança dos alimentos, são agora mais do que noutras alturas, inicialmente desconsideradas. Neste contexto, as produções locais e os circuitos curtos de proximidade perspetivam-se como uma alternativa eficaz de distribuição de produtos alimentares. Por outro lado, a pandemia provocada pela COVID-19 veio apelar, mais do que em outras alturas, à necessidade de ser enfatizado o que é produzido e distribuído localmente. Para além dos benefícios económicos para os próprios produtores e benefícios ambientais para o meio ambiente, salientam-se ainda os benefícios socias decorrentes desta prática, já que se fomenta a confiança entre produtores e consumidores. Daí que com base numa investigação desenvolvida em concelhos pertencentes à Região Viseu Dão Lafões, no Centro de Portugal, o objetivo deste trabalho é o de investigar o impacto da pandemia provocada pela COVID 19 ao nível os circuitos curtos de proximidade. Os resultados obtidos sugerem que a pandemia provocada pela COVID 19 consciencializou para a importância das produções locais e das temáticas relativas à qualidade dos produtos.
- Olive Oil Tourism: Innovative or Traditional Form of Rural Tourism?Publication . Pato, Maria LúciaOlive oil tourism is a unique and rapidly growing segment of agritourism, particularly popular in Mediterranean countries Portugal, where olive oil production has deep cultural and historical roots. At the heart of this form of tourism is the opportunity for visitors to explore the olive-growing process, engage in tastings, and immerse themselves in the traditions surrounding one of the world's most ancient food products. However, modern innovation is playing a pivotal role in revitalizing these traditions, making olive oil tourism not just a journey into the past but a dynamic exploration of the future. Based on a qualitative analysis of five farms of olive oil tourism, findings indicate the focus on tradition and values of the past as the main ingredient to promote the offer of olive oil tourism. Through this blend of old and new, olive oil tourism not only preserves heritage but also paves the way for a sustainable and vibrant future. Innovation through tradition is indeed a path that must be considered by scholars and practitioners in the promotion of olive oil tourism and related products.
- Predictive Artificial Intelligence Approaches of Labour Use in the Farming SectorPublication . Martinho, VítorIt is not expected that the agricultural sector absorbs a great part of the employment in developed economies with a dynamic industry and services sector. When the percentage of employment in agriculture is high, this may be a sign of the weak performance of the farms. Every country wants to have a developed farming sector to not compromise the dynamics and performance of the economy. In any case, agricultural employment plays a fundamental role, particularly in rural spaces and in contexts of temporary crises in the remaining economy. Taking into account these motivations, this chapter aims to highlight the main approaches and variables that may be considered to predict labour use in the European Union farms. To achieve these aims, European Union agricultural statistics were considered, as well as models based on the new technologies associated with the digital transition worldwide. The results found may provide pertinent suggestions for a more sustainable farming sector, where the social contributions may be improved.
- Predictors of Interest Paid in the European Union’s Agricultural SectorPublication . Martinho, VítorIn general, the interest paid does not assume a relevant dimension in the overall costs present in the European Union farms. In fact, considering the agricultural sector characteristics, the Common Agricultural Policy measures and the dynamics of the banking sector in the European Union, the interest paid is a small part of the costs supported by the farmers. In any case, banking loans are fundamental for farming investments and in this way, it is important to understand their respective context. Considering these motivations, this research proposes to consider artificial intelligence approaches and data from the Farm Accountancy Data Network to identify the models with higher accuracy and the most important indicators to predict the interest paid by the farms of the European Union. The contributions of this research bring relevant insights into the dynamics of the bank loans for the European Union agricultural sector and the respective measures inside the Common Agricultural Policy framework.
- Machine Learning Methodologies, Wages Paid and the Most Relevant PredictorsPublication . Martinho, VítorThe agricultural sector worldwide has an economic dimension related to the remuneration of the production factors applied in the sector, an environmental contribution associated with the sustainability of rural places and a social dimension related to the employment creation and the consequent level of remuneration of the labour. The question here is about the level of wages paid in the agricultural sector across the European Union countries and about the main factors that may be taken into account to predict the level of these wages paid to agricultural workers. This research intends to select the models with better precision to predict the wages paid in the European Union agriculture and to suggest important predictors from the enormous number of indicators that may be identified in the farms. The findings obtained may be considered relevant support for the design of social and agricultural policies in the European framework.
