- The SDG18 and the two cultural purposes at large: towards a new pillar of sustainability?Publication . Seixas, Paulo Castro; Dias, Ricardo Cunha; Lobner, Nadine; Vidal, Diogo Guedes; Seixas, Paulo Castro; Dias, Ricardo Cunha; Lobner, Nadine; Leal Filho, Walter; Vidal, Diogo Guedes; Dinis, Maria Alzira PimentaIn the past 6 years that have followed the initial launch of the Sustainable Development Goals (SDGs), a discussion on its extension (SDG + 1/SDG18) emerged. The SDG18 quest is interpreted as a collective pursuit for meaning on SDGs and the future of our planet, based on 23 different proposals. This article aims at a detailed analysis of these 23 proposals and their meanings within the SDGs framework which directly connects with urban trends and transitions. Methodologically, this paper is supported by online research on SDG18 proposals and a content analysis. This leads to three main categories based on the criteria of aims/claims for the SDG18: (1) country ownership as national interest; (2) societal cooperation as both a fear and an emphasis of the SDG framework and (3) cultural purposes. Throughout our analysis, the latter category resonates with the core dyads of humanity: nomadic–sedentary and rural–urban. The category was divided in two subcategories: an Anthropic Techno-explosion Purpose (a nomadic-urban-progress trend) and an Ecologic Consciousness Purpose (a sedentary-rurban-degrowth trend). These are what we describe as the two Purposes at Large, framing the dialogue about our future as human beings. Finally, assuming the relevance of this dialogue, we urge the General Secretary of the UN to create an annually SDG18 Forum.
- Lifting the veil of complexity, demanding for convergence: an introduction to the book “Planetary Health and Climate Change”Publication . Vidal, Diogo Guedes; Lopes, Hélder Silva; Dinis, Maria Alzira Pimenta; Leal Filho, Walter; Leal Filho, Walter; Vidal, Diogo Guedes; Dinis, Maria Alzira PimentaHuman-induced alterations to the Earth’s climate, primarily through the release of greenhouse gases, have far-reaching implications for ecosystems and both human and non-human health. However, treating climate change exclusively as an external force continues to limit human potential to effectively address it. This introductory chapter to the book “Planetary Health and Climate Change” explores concepts aimed at bridging the chasm created by this separation, while addressing the socio-ecological hurdles humanity currently face. Despite these efforts, there remains a lack of imagination, a vital aspect to envisioning alternative scenarios and solutions. Among these complexities, the concept of planetary health emerges as a holistic framework that goes beyond conventional public health paradigms. This chapter also delves into the idea of convergence, i.e., a combination of perspectives, disciplines, and approaches to navigate through complex socioecological challenges. It highlights the importance of moving beyond binary thinking and embracing varied worldviews to tackle compounded crises. Through convergence with the lens of planetary health, we can redefine health, prioritize cooperation over competition, and empower ourselves to address the challenges posed by a changing climate.

- Assessing circularity in the agri-food sector: a case studyPublication . Scandurra, Federica; Salomone, Roberta; Caeiro, Sandra; Gulotta, Teresa Maria; Sandra Caeiro2The agri-food sector (AFS) faces challenges in providing affordable and healthy food for an increasing population. In this context, Circular Economy (CE) has gained interest as an approach to drive the food system to sustainability. However, circularity does not always lead to sustainability. The lack of a defined set of metrics to monitor CE in the sector makes it relevant to select assessment approaches that capture CE's contribution to sustainability. For this reason, the present study aims to support the dairy cooperative Fattoria della Piana, a best case of CE, in assessing its circular strategies. The study links Life cycle assessment (LCA) with circularity indicators collected in the literature. This preliminary study analyses the core of the circular exchanges of the cooperative, represented by the anaerobic digestion and combined heat and power plant (AD-CHP) plant. The study presents a valuable assessment approach for companies in the sector, highlighting the complexity of assessing CE. LCA evidenced valuable credits from avoiding mineral fertilizer and natural gas use thanks to their substitution with the treatment plant's outputs. Indicators suggest its ability to recirculate waste for energy purposes and nutrients. Future studies will explore the overall cooperative' system, evaluating the three dimensions of sustainability.

- Sustainability practices impacts on supplier sustainability risks and sustainability performance: an empirical study of brazilian companiesPublication . Romano, Andre; Ferreira, Luis Miguel D. F.; Caeiro, SandraThis study explores the influence of sustainability practices on supplier sustainability risks and sustainability performance in Brazilian companies, offering key insights into how behavioral and technical practices impact these crucial areas. Data were collected from 152 Brazilian companies across various sectors. The theoretical framework was tested using partial least squares structural equation modeling. The research findings highlight that implementing behavioral sustainability practices has a positive effect on reducing supplier sustainability–related risks and improving overall sustainability performance in supply chains. These practices, focused on fostering sustainable behaviors within organizations and among suppliers, play a critical role in mitigating sustainability risks and enhancing long-term performance. Unexpectedly, the study did not confirm the predicted relationship between technical sustainability practices and improvements in supplier sustainability–related risks and performance. This surprising result challenges traditional assumptions about the effectiveness of technical practices in improving supply chain sustainability performance. By uncovering the distinct impact of behavioral versus technical sustainability practices, the study provides valuable insights for both researchers and practitioners. It emphasizes the importance of promoting behavioral change to achieve meaningful sustainability outcomes. The findings have practical implications for companies aiming to enhance their sustainability strategies and manage sustainability risks more effectively within their supply chains, making this research a significant contribution to sustainable management and supply chain theory.
- Assessment of the genotoxic hazard of estuarine sediments using an integrative approach with LacZ Plasmid-Based transgenic micePublication . Pinto, Miguel; Sacadura, Joana; Costa, Pedro M.; Caeiro, Sandra; Louro, Henriqueta; Silva, Maria J.Under the influence of multiple anthropogenic pressures, from industrial to agricultural activities, estuaries have long been regarded as particularly sensitive ecosystems to contamination. The present study aimed at investigating the genotoxic potential of a contaminated sediment sample from an urban and industrial area of the Sado Estuary, by combining the analysis of multiple endpoints in the LacZ plasmid-based transgenic mouse model exposed for 28 days to contaminated estuarine sediment extracts through drinking water. The DNA and chromosome damaging effects were monitored in peripheral blood at 7-day intervals using the standard and enzyme-modified Comet assay, as well as the micronucleus assays in peripheral blood cells. After euthanasia, DNA damage was analyzed in several mouse tissues, and LacZ mutant frequencies were determined in the liver. Livers were also surveyed for histopathological analysis. A time-dependent increase in micronuclei frequency was seen at all tested doses, in spite of no induction of DNA damage in any organ or mutation induction in the liver of exposed mice. The liver from mice exposed to sediment extracts did not reveal major alterations besides evidence of inflammation. Overall, the integration of the endpoints analyzed in the mice is suggestive of potential chronic, rather than acute, adverse effects in vivo, and points to the need for further research in the resident human population in the area. This experimental design can be used to assess the genotoxicity of complex environmental mixtures, understand how they work, and reduce costs and resources while speeding up data collection and interpretation.
