- Flood susceptibility assessment through statistical models and HEC-RAS analysis for sustainable management in essaouira province, MoroccoPublication . Khouz, Abdellah; Trindade, Jorge; Santos, Pedro Pinto; Oliveira, Sérgio; Bchari, Fatima El; Bougadir, Blaid; Garcia, Ricardo; Reis, Eusébio; Jadoud, Mourad; Saouabe, Tarik; Rachidi, SaidFloods are natural disasters that often impact communities living in low-lying areas in the northern and central parts of Morocco. In this study, our aim was to create a flood susceptibility map using three methods; the hierarchy process (AHP) frequency ratio model (FR) and the weights of evidence (WoE) model. We extensively examined the area identified by these approaches using a hydraulic analysis software called HEC-RAS (version 6.3.1). Our analysis focused on the Essaouira watersheds in Morocco, where we identified around 197 flood locations. Out of these, we randomly selected 70% for modeling purposes while the remaining 30% were used for validation. Ten factors that influence floods were considered, such as slope, elevation, proximity to rivers, drainage density, stream order, land use patterns, rainfall data, lithology (permeability level) index (TWI), and curvature. We obtained these factors from data sources. Finally, we generated a flood susceptibility map and evaluated its accuracy by calculating the area under the curve (AUC). The validation results confirmed that all three models were robust and effective with an AUC of 90. Moreover, the research uncovered a trend of vulnerability with the most susceptible area being in close proximity to the city of Essaouira along the Oued Ksob. A detailed analysis using HEC-RAS was conducted at this identified location, pinpointing the village of Diabat as highly exposed. These findings hold significance for flood management, empowering decision makers, scholars, and urban planners to make informed choices and implement strategies that can minimize the impact of floods in susceptible regions while minimizing potential damages.
- A evolução das condições ambientais na várzea de Maceira (estuário do Rio Alcabrichel, oeste de Portugal) no Holocénico SuperiorPublication . Aleixo, Cristiana; Ramso-Pereira, Ana; Trindade, JorgeApresenta-se um estudo de sedimentologia de duas sondagens com 5 m de profundidade, situadas no sector médio do estuário do Rio Alcabrichel, no litoral oeste de Portugal. Trataram-se laboratorialmente 409 amostras (2cm cada) e calcularam-se parâmetros estatísticos para cada amostra através da % da fração arenosa (>63μm). Com base na análise sedimentológica identificaram-se 4 unidades sedimentológicas (Ucf), que permitiram estabelecer a história ambiental deste estuário, nos últimos 5000 anos: Ucf1 corresponde a um estuário com influência marinha (presença de gastrópodes marinhos); Ucf2 demonstra um estuário com influência marinha para o topo, porém na sua parte basal é estéril em biorrestos; Ucf3 testemunha uma fase de enchimento sedimentar do corpo estuarino; Ucf4 evidencia a situação atual, com domínio da influência fluvial no estuário interior do Rio Alcabrichel, marcado, possivelmente, por episódios de enxurrada, como atesta o aumento de areia e cascalho.

- Sustainable land use: policy implications of systematic land regularization in MozambiquePublication . Carrilho, João; Dgedge, Gustavo; Santos, Pedro Pinto; Trindade, JorgeSecurity of land tenure is key to achieve the sustainable development goal of eradicating poverty and can be improved through the regularization of rights to land, property, and natural resources. Making cities and human settlements sustainable, requires participatory and integrated land use planning, accounting for the land’s po tential and constraints, with a view to medium and long-term use. The government of Mozambique is actively promoting a process of massive regularization, under common terms of reference for service providers. The terms of reference also intend to achieve a linkage between regularization and community land use plans. The aim of this research is to assess the robustness of such plans to detect and overcome potential conflicts between the given and the potential land use, as well as constraints, weaknesses and threats. This research uses a mixed documental analysis to undertake an ex-ante assessment of 15 participatory community land use plans. Five categories are assumed as a reference of good practices in land use planning suggested by universal and African literature. It was found that the common terms of reference and guidelines promote participatory capacity and provides general directions of community development. However, good practices of land use planning such as effective participation in all phases, alternative scenarios for future land use, regional integration, and disasters risk management are less promoted. It is suggested that the guidelines go beyond the immediate needs of land register, to consider that such interventions in rural areas shape the culture of land use, which, in turn, will influence sustainability in higher level settlements.
- Integrating sustainable approaches in distance learning universities: the experience of Universidade AbertaPublication . Mapar, Mahsa; Nicolau, Paula Bacelar; Ferreira, Célia; Martins, Rute; Martinho, Ana Paula; Pereira, Pedro; Simão, João; Teixeira, Teresa; Trindade, Jorge; Fernandes, Paula Vaz; Caeiro, SandraOne of the key components in practicing sustainability and developing a sustainable Higher Education Institution (HEI) is the role played by the institution community including students and its staff, both administrative and academics according to a whole-campus approach. However, there is still a lack of how to integrate sustainability-related approaches into the HEIs, by involving the whole community of the HEI, in particular in distance-learning institutions. Recognizing this lack, Universidade Aberta (UAb), the Portuguese Distance Learning University, has recently integrated sustainability approaches into the University actions by establishing the “UAb Sustainable Campus Group” in 2021. In line with Agenda 2030, the Group promotes the sustainability approaches at UAb in 5 core elements of sustainability actions at HEIs: i) planning and administration, ii) operation and innovation, iii) academia and research, iv) assessment and reporting, and v) involvement with the community. This paper aims to reveal the recent sustainability initiatives (2021-2023) carried out by the Group and enlighten how a distance-learning University's actions, programs, and approaches have been integrated into the core elements of sustainability actions at HEIs. Several steps were implemented to address sustainability initiatives at UAb based on the proposed framework, considering: 1) “planning and administration”, by the formal commitment to sustainability that arose in the UAb Strategic Plan (2019-2023) to enforce sustainability initiatives centered on people and social commitment; 2) “operation”, by UAb contribution to the resource efficiency programs; 3) “academia and research”, by designing a micro-credential module entitled “Sustainable Development Goals (SDGs)”, that were piloted in the academic year 2022-2023 and were evaluated the students’ knowledge improvement on SDGs and sustainability and their perceptions on the effectiveness of the training through pre- and postquestionnaires; 4) “assessment and reporting”, through self-assessment and reporting tools, among them, Time Higher Education Impact Ranking, which ranked the UAb sustainability initiatives towards SDGs 4, 5, 6, 8, 10, and 17. Also, with the collaboration of the administrative staff, the UAb Ecological Footprint (EF) was self-assessed through the University Ecological Footprint Calculator, which allows HEIs to calculate their consumption of natural resources and ecosystem services within the direct and indirect responsibilities of the administration, by bearing in mind the specific feature of distance learning. The results for “planning and administration” showed the UAb commitment to sustainable campus by the signatory of several associations, e.g., RCS-Portugal, AASHE - Association for the Advancement of Sustainability in Higher Education, and Lisbon Green Commitment to implement a set of measures to reduce the environmental impacts by 2030. In the “operation” element, the results revealed the UAb contribution to the Resource Efficiency Program in Public Administration - ECO.AP 2030 to reduce the consumption of resources and respective Greenhouse Gas emissions facilities, as well as the Energy Saving Plan (2022-2023). The results of the “academia and research” element based on the SDGs course showed the students’ knowledge improvement of both Sustainability and SDGs and a high level of satisfaction with the training, mainly appreciating the “diversified learning resources”. The results of the “assessment and reporting” based on THE displayed the UAb improvement on SDGs 4 and 5. The results of the EF calculator disclosed that “staff labour” was the main driver of the UAb Footprint in direct responsibility, whereas “energy consumption at home” was the main indirect contributor to the UAb Footprint, which showed the effect of distance learning on the results. Future work of the Group includes offering the SDGs micro-credential, targeting also public and private organizations, and later as a formal curricular unit in various degrees, thus enhancing the “involving the community” element. Also, based on the results of the assessment tools, the major drivers of unsustainability at UAb will be identified to assist the necessary improvement to reduce the environmental impact of UAb, thus reinforcing its commitment to building a more sustainable community. The framework for the implementation of sustainability in UAb can be adapted and tested in other HEI to produce robust knowledge and action in this context.
- Avaliação do perigo de inundação de áreas urbanas expostas à subida do nível do mar em Portugal continentalPublication . Silva, Andreia Alves da; Trindade, Jorge; Rocha, JorgeA ocupação antrópica no litoral português sofreu uma mudança de paradigma no século XX. Um espaço outrora temido pela população, apenas frequentado sazonalmente por comunidades piscatórias, tornouse atrativo para a fixação de residentes (Gaspar de Freitas, 2007). Até à atualidade, têm-se registado variações populacionais positivas nas NUTS III que abrangem o litoral, contando com 82,5 % da população residente em Portugal, em 2021 (INE., 2023). A perspetiva de crescimento urbano no litoral, conjugada com um contexto de mudança climática, num país com 980 km de fronteira com o oceano (no território continental), exacerba as necessidades de salvaguarda da população que se expõe a fenómenos como a subida do nível do mar (SNM) e erosão costeira. Em Portugal, as taxas de erosão costeira são, em algumas áreas, >8 m/ano (Ponte Lira et al., 2016), e quanto à SNM, prevê-se que se mantenha até 2100, ano em que, caso se verifique o cenário Representative Concentration Pathway (RCP) 8.5, a sobreelevação do nível do mar atinja 80 cm em Portugal continental (NASA/IPCC). Tais fenómenos, acrescidos da ocorrência de eventos destrutivos (e.g.: tempestade Hercules), exacerbam a necessidade de gestão resiliente da orla costeira. Este trabalho pretende avaliar e mapear a exposição das comunidades urbanas face à SNM, em Portugal continental. Estabeleceu-se, primeiramente, uma metodologia de determinação da altura da coluna de água prevista baseada nos cenários RCP 2.6, 4.5 e 8.5, para os anos de 2040, 2070 e 2100, com informações sobre: a maré, a sobrelevação do nível do mar de origem meteorológica, o espraio de onda e, a SNM. Complementarmente, e baseado nos declives, distância às vias e ao tecido urbano, e nas dinâmicas passadas de uso do solo, projetou-se, com recurso a algoritmos de machine learning, a evolução do tecido urbano. Por fim, combinando os resultados, desenvolveram-se perfis municipais de exposição à SNM. Os resultados obtidos indicam que, em 2040, cerca de 65 km² sejam diretamente afetados por inundações costeiras, dos quais mais de 1/5 sejam áreas urbanas. Como possíveis soluções, apresenta-se medidas preventivas de mitigação dos riscos, como a definição de áreas críticas de construção urbana, e planeamento a longo-termo de relocalização antrópica.
