The role of art in coastal and marine sustainability
Matias, Ana; Carrasco, A. Rita; Pinto, Bruno; Reis, JaimeSustainability is a universal goal that requires balancing social, economic and environmental dimensions, and that applies to both terrestrial and marine environments. Several authors argue that arts are valuable tools to frame and engage with current environmental issues related to sustainability, including pollution, climate change and biodiversity loss. Accordingly, our research question is: What is the role...
From art to the sustainability of coasts and seas
Matias, Ana; Carrasco, A. Rita; Pinto, Bruno; Reis, JaimeSustainability is a universal goal by which human development balances social, economic, and environmental dimensions, applicable to both terrestrial and marine environments. Several authors argue that arts are valuable tools to frame and engage with current environmental issues related to sustainability, including pollution, climate change, and biodiversity loss. In this work, we ask - what is the role of art ...
Exploring open-source multispectral satellite remote sensing as a tool to map l...
Blount, Tegan R.; Carrasco, A. Rita; Cristina, Sónia; Silvestri, SoniaFrom an ecological and socio-economic perspective, salt marshes are one of the most valuable natural assets on Earth. As external pressures are causing their extensive degradation and loss globally, the ability to monitor salt marshes on a long-term scale and identify drivers of change is essential for their conservation. Remote sensing has been demonstrated to be one of the most adept methods for this purpose ...
Vertical intertidal variation of organic matter stocks and patterns of sediment...
de los Santos, Carmen B.; Lahuna, François; Silva, André; Freitas, Cátia; Martins, Márcio; Carrasco, A. Rita; Santos, RuiTidal coastal wetlands, common home to seagrass and salt marshes, are relevant carbon sinks due to their high capacity to accumulate and store organic carbon in their sediments. Recent studies demonstrated that the spatial variability of this organic carbon within the same wetland system can be significant. Some of the environmental drivers of this spatial variability remain understudied and the selection of th...
Carbon and nitrogen stocks and burial rates in intertidal vegetated habitats of...
Martins, Márcio; de los Santos, Carmen B.; Masqué, Pere; Carrasco, A. Rita; C. Veiga-Pires, C.; Santos, RuiCoastal vegetated ecosystems such as saltmarshes and seagrasses are important sinks of organic carbon (OC) and total nitrogen (TN), with large global and local variability, driven by the confluence of many physical and ecological factors. Here we show that sedimentary OC and TN stocks of intertidal saltmarsh (Sporobolus maritimus) and seagrass (Zostera noltei) habitats increased between two- and fourfold along ...
No âmago da Ria Formosa: praias lagunares e sapal
Carrasco, A. Rita; Matias, AnaAs praias lagunares encontram-se na zona entremarés do interior da Ria Formosa, em locais protegidos da ondulação. São ambientes onde há acumulação de sedimentos finos e areia, essencialmente sujeitos à ação das correntes de maré. As suas margens comunicam com sapais e canais de maré. Tanto as praias lagunares como os sapais detêm elevada importância ecológica e albergam inúmeras atividades económicas. As praia...
Past and future marsh adaptation: Lessons learned from the Ria Formosa lagoon
Carrasco, A. Rita; Kompiadou, Katerini; Amado, M.; Matias, AnaIt is rational to assume that salt marshes in regions where sediment loads are high should remain stable or pro grade when facing a range of sea-level scenarios, whereas those in sediment-poor systems may erode or drown. Despite extensive theoretical and laboratory studies, additional marsh 'persistence' indicators under human pressures and accelerated sea-level rise rates are still needed. This study investiga...
Engaging children in geosciences through storytelling and creative dance
Matias, Ana Catarina; Carrasco, A. Rita; Ramos, Ana A.; Borges, R.Natural sciences have traditionally been disseminated in outreach activities as formal, one-way presentations. Nevertheless, innovative strategies are being increasingly developed using arts, gaming, and sketching, amongst others. This work aimed at testing an alternative and innovative way to engage non-expert audiences in ocean and coastal geology through a combination of scientific concept explanations and c...
Barrier island resilience assessment: Applying the ecological principles to geo...
Kombiadou, Katerina; Matias, Ana; Costas, Susana; Carrasco, A. Rita; Plomaritis, Theocharis A.; Ferreira, ÓscarApplying the ecological resilience principles to barrier island geomorphological evolution requires approaches that perceive and interpret resilience far from predefined barrier characteristics and static views. Accepting that barrier islands, like all natural systems, are dynamic and adaptively changing in response to external disturbances is fundamental to the formulated approach. To this aim, geomorphologica...
Relatório setor segurança de pessoas e bens: vulnerabilidades atuais e futuras
Ferreira, Andreia; Oliveira, André; Dias, Luís Filipe; Fernandes, Luís; Brito, David; Braunschweig, Frank; Sampath, Ruwan; Moura, DelmindaAs alterações no clima constituem um fator a ter em conta no setor da segurança de pessoas e bens. Muitos dos impactos associados às alterações climáticas exacerbam ou alteram ameaças já existentes, como aquelas associadas a eventos extremos, inundações e secas (Sperling e Szekely, 2005). Os cenários de alterações climáticas projetados para Portugal tornam necessário um esforço de adaptação do Sistema de Proteç...
