- A bibliometric analysis on designing urban green and blue spaces related to environmental and public health benefitsPublication . de Sousa Silva, Catarina; Bell, Simon; Lackóová, Lenka; Panagopoulos, ThomasAbstract: Humans and nature have always been connected. Meanwhile, with the industrial revolution, landscapes have become more artificial, reducing the human–nature relationship. Urban design should follow biophilic principles to reconnect people with nature, mitigate climate change, improve air quality, restore biodiversity loss, and solve social problems. Poor air quality affects people’s health, and vegetation plays a crucial role in purifying the air. Similarly, contact with nature benefits physical and mental health and well-being. However, there is no consensus on how urban design can be beneficial for improving air quality and human health. This review paper aims to provide a comprehensive evaluation of evidence linking nature-based solutions (NBSs), air quality, carbon neutrality, and human health and well-being. Five hundred articles published between 2000 and 2024 were analysed. A number of publications studied the benefits of green infrastructure in improving air quality, carbon sequestration, or the influence of green spaces on human health. The topic of NBSs has recently emerged related to air quality, health, and promoting physical activity, as has accessibility to green spaces and mental health, also associated with blue spaces and residential gardens. The results revealed the gaps in the literature on how to design green and blue spaces to tackle environmental and public health crises simultaneously.
- Tracking tourism waves: insights from automatic identification system (AIS) data on maritime–coastal activitiesPublication . Ramos, Jorge; Drakeford, Benjamin; Costa, Joana; Madiedo Camelo, Ana Maria; Leitão, FranciscoAbstract: The demand for maritime–coastal tourism has been intensifying, but its offerings are sometimes limited to a few activities. Some of these activities do not require specific skills or certifications, while others do. This study aimed to investigate what type of activities are carried out by tourism and recreational vessels in the coastal area of the central Algarve (Portugal). To this end, data from the automatic identification system (AIS) of recreational vessels was used to monitor and categorise these activities in a non-intrusive manner. A model (TORMA) was defined to facilitate the analysis of AIS data and relate them to five independent variables (distance from the coast, boat speed, bathymetry, seabed type, and number of pings). The results of the analysis of more than 11 thousand hourly AIS records for passenger, sailing, and charter vessels showed that the 14 most regular ones had strong seasonal patterns, greater intensity in summer, and spatial patterns with more records near some coastal cliffs. This study provides valuable information on the management of motorised nautical activities near the coast and at sea, contributing to more informed and effective tourism regulation and planning.
- “E-migrantes” y las redes sociales digitales en la construcción de un espacio transnacional: el caso de los peruanos en PortugalPublication . Marques, João Filipe; Calla Jesús de Sousa, YeseniaEste artículo busca comprender la influencia de las redes sociales digitales (RSD) en la vida cotidiana de los inmigrantes. Se pretende entender de qué manera estas prácticas contribuyen a la construcción de un espacio transnacional, considerando que esta expresión se refiere al mantenimiento de lazos entre los inmigrantes y su país de origen, así como a la formación de vínculos con sus compatriotas que también viven en el extranjero. El artículo recurre al concepto de “e-migrantes” para designar a aquellos que, mediante el uso de tecnologías de la información y la comunicación (TIC), permanecen conectados entre sí y con su país de origen. Como caso empírico, se estudia a los inmigrantes peruanos residentes en Portugal. La pregunta de investigación fue la siguiente: ¿de qué forma la comunidad peruana que vive en Portugal utiliza las RSD? El artículo se centra en las prácticas que emergen de la apropiación de las plataformas digitales — en particular, la construcción de “comunidades virtuales” — a través de una metodología mixta que incluye el análisis de un conjunto de entrevistas semiestructuradas, una encuesta en línea y datos estadísticos sobre el uso de las RSD.
- Developing high-efficiency PCR mini-barcoding to enforce conservation efforts against illegal trade and habitat loss of endangered Taxus L. in the HimalayasPublication . Din, Salahud; Ali, Haidar; Panagopoulos, Thomas; Alam, Jan; Malik, Saira; Sher, HassanEnvironmental and ancient DNA are mostly present in degraded forms in nature. Plant forensics is necessary for plants like Taxus (Taxaceae), which is a medicinal, as well as poisonous, endangered plant. We designed a study to develop high-efficiency PCR mini-barcoding primers for the identification of Taxus. We collected environmental materials, fresh and old Taxus specimens from natural habitats, herbaria, and ex situ propagation sites. Taxon-specific mini-barcoding primers were prepared through primer3. All the primers were amplified onto Taxus specimens and environmental samples having Taxus DNA, while no amplification on fresh and herbarium specimens other than Taxus was noted. DNA sequencing of amplified regions of matK, ITS, and rbcL yielded lengths of 117, 175, and 200 bp. Blast taxonomy showed 100% identification power at the genus level, while 75–93% at the species level, and identified a total of 30 taxa within the genus Taxus, comprising 16 species, 5 varieties, 2 hybrids, and 7 variants. ITS was the most specific for genus identification, followed by matK and rbcL. Environmental, trade, socio-economic, and toxicological crimes were also identified. Our high-efficiency PCR mini-barcoding method can be useful in the prevention of Taxus illegal trade and habitat degradation to mitigate climate change in the Himalayan region of Pakistan.
- Charting the course: real‐world application of sustainability and innovation principles in the portuguese blue economy firmsPublication . Elston, Jennifer Nicole; Pinto, Hugo; Nogueira, CarlaThe blue economy has emerged as a key sector for linking sustainability and innovation, yet existing research has largely overlooked how firms operationalize these processes in practice. This study addresses that gap by asking: How do Portuguese blue economy firms embed sustainability-oriented innovation (SOI) into their strategies, and what institutional conditions enable or constrain it? This study explores SOI through an analysis of five Portuguese firms. Adopting a qualitative approach, it employs semistructured interviews, supported by content comparison techniques and thematic coding. The findings indicate that stakeholder collaboration, circular economy principles, and renewable energy integration support sustainability performance, whereas financial constraints, regulatory inefficiencies, and bureaucratic hurdles limit broader adoption. Drawing on institutional theory, the resource-based view, and the triple bottom line framework, the study contributes theoretically by showing how SOI is negotiated between institutional pressures and firm capabilities, revealing tensions between compliance and strategic agency. The study underscores the importance of institutional support, stakeholder engagement, and adaptive business strategies in overcoming systemic barriers. These results provide practical direction for policymakers and business leaders, highlighting the need for streamlined regulation, targeted financial incentives, and cross-sector collaboration. For policymakers, this means aligning incentives with SME capacities and building collaborative governance platforms; for firms, it means leveraging partnerships and resource-based advantages to scale sustainable business models. By clarifying both institutional dynamics and firm-level practices, the article advances understanding of how sustainability transitions are enacted within the blue economy.
- A review of research into lifestyle mobilities and digital nomadismPublication . Cohen, Scott; Hannonen, OlgaLifestyle mobilities refers to ways of life oriented around ongoing geographic mobility. This article first provides a history of lifestyle mobilities and how it is analytically distinct. We turn to the state-of-the-art in lifestyle mobilities research through a focus on digital nomadism. Our emphasis is on lifestyle mobilities’ relevance for tourism, its infrastructure and politicisation – via geopolitics, geoarbitrage and gentrification, and the need for greater research diversity. We map a future research agenda centred on tensions of transitioning out, precarity and emplacement. The article also launches the Annals of Tourism Research Curated Collection on lifestyle mobilities. The Collection contains all past articles published in Annals of Tourism Research on the topic, and continues to grow as new articles are added.
- Evaluation of the impact of sustainable drainage systems (SuDSs) on stormwater drainage network using giswater: a case study in the metropolitan area of Barcelona, SpainPublication . Araújo, Suelen; Lança, Rui; Silva, Carlos Otero; Torret, Xavier; Granja Martins, Fernando Miguel; Maria Neto Paixão Vazquez Fernandez Martins, HelenaTo mitigate the impacts of urbanisation and the attendant surface sealing, appropriate measures are required when adapting urban spaces and drainage infrastructure. In this context, the deployment of Sustainable Drainage Systems (SuDSs) has emerged as a viable alternative, delivering highly positive outcomes by enhancing hydrological, hydraulic and landscape performance while restoring ecosystem services to the community. This study evaluates the relative performance of five SuDS typologies, green roofs, bioretention cells, infiltration trenches, permeable pavements, and rain barrels, implemented in a 64 ha subbasin of the metropolitan area of Barcelona, Spain. Using Giswater integrated with the SWMM, the stormwater drainage network was modelled under multiple rainfall scenarios. Performance was assessed using two qualitative indicators, the junction index (Ij) and the conduit index (Ic), which measure surcharge levels in manholes and pipes, respectively. The results show that SuDS implementation affecting 42.8% of the drained area can enhance network performance by 35.6% and reduce flooded junctions by 67%. Among the typologies, rain barrels and bioretention cells were the most effective. The study concludes that SuDS construction, supported by open-source tools and performance-based indicators, constitutes a replicable and technically robust strategy for mitigating the effects of surface sealing and increasing urban resilience.
- GIS-based site selection for agricultural water reservoirs: a case study of São Brás de Alportel, PortugalPublication . Dziuba, Olga; Custódio, Cláudia; Silva, Carlos Otero; Granja Martins, Fernando Miguel; Lança, Rui; Maria Neto Paixão Vazquez Fernandez Martins, HelenaIn the São Brás de Alportel municipality, water scarcity poses a significant constraint on agricultural activities. This study utilises Remote Sensing (RS) and Geographical Information Systems (GISs) to identify existing irrigated areas, delineate catchment basins, and select the most suitable sites for the installation of new surface water reservoirs. First, the principal territorial components were characterised, including physical elements (climate, geology, soils, and hydrography) and anthropogenic infrastructure (road network and high-voltage power lines). Summer Sentinel-2 satellite imagery was then analysed to calculate the Normalised Difference Vegetation Index (NDVI), enabling the identification and classification of irrigated agricultural parcels. Flow directions and accumulations derived from Digital Elevation Models (DEMs) facilitated the characterisation of 38 micro-catchments and the extraction of 758 km of the drainage network. The siting criteria required a minimum setback of 100 m from roads and high-voltage lines, excluded farmland currently in use, and favoured mountainous areas with low permeability. Only 18.65% (2854 ha) of the municipality is agricultural land, of which just 4% (112 ha) currently benefits from irrigation. The NDVI-based classification achieved a Kappa coefficient of 0.88, indicating high reliability. Three sites demonstrated adequate storage capacity, with embankments measuring 8 m, 10 m, and 12 m in height. At one of these sites, two reservoirs arranged in a cascade were selected as an alternative to a single structure exceeding 12 m in height, thereby reducing environmental and landscape impact. The reservoirs fill between October and November in an average rainfall year and between October and January in a dry year, maintaining a positive annual water balance and allowing downstream plots to be irrigated by gravity. The methodology proved to be objective, replicable, and essential for the sustainable expansion of irrigation within the municipality.
- TikTok in higher education: a learning tool to connect with industry and develop students' digital skillsPublication . López-Carril, Samuel; Carpenter, Jeffrey P.; Watanabe, Nicholas M.; Ribeiro, TiagoTikTok has rapidly become a mainstream social media platform, particularly popular among younger populations. However, young people's perceptions of TikTok's use as a teaching–learning tool remain largely unexplored. To address this literature gap, this study involved an educational intervention in which TikTok was integrated into sport management classes at a Spanish university through active learning methodologies. Specifically, it sought to assess changes in students’ perceptions before and after the intervention across three key dimensions: TikTok’s usefulness as a teaching tool, its contribution to professional development, and its potential for industry engagement. To assess students' perceptions of TikTok, a pre-test and post-test were conducted with 48 students (71% male, 29% female) enrolled in the course. Quantitative findings revealed statistically significant positive changes across all three dimensions, suggesting that the intervention positively impacted students’ perceptions of TikTok’s educational, professional, and industry-related value. These findings were reinforced by qualitative data collected through open-ended responses, in which students highlighted TikTok as a creative, motivating, and professionally relevant learning tool. The results of this study offer both theoretical and practical insights that may be valuable to educators and educational institutions considering the strategic integration of social media such as TikTok into higher education.
- Women and pro-environmental initiatives in tourism: the intersection of gender dynamics and environment issuesPublication . Bagheri, Fatemeh; Esfehani, Minoo; Ghaderi, Zahed; Mohajer, Boshra; Abdi, NaserWomen’s involvement, gender equality, and environmental challenges are critical concepts in tourism development, particularly in patriarchal systems where hierarchical value systems create challenges for both nature and women. However, the theoretical framework addressing these issues remains underexplored. This study examined how women interpret their motivations and challenges in these contexts while contributing to tourism-related environmental conservation and navigating patriarchal gender norms. It investigated the lived experiences of Iranian women actively engaged in tourism related conservational initiatives. The findings revealed that their commitment to pro-environmental initiatives is driven by an intrinsic connection to nature and a desire to resist gender inequalities and challenge male-dominated structures. Despite facing challenges stemming from patriarchal structures, they demonstrate collective resilience against gender stereotypes. Additionally, their participation in tourism pro-environmental projects fosters trust and social recognition, driving incremental social change. This study makes a strong theoretical contribution by exploring gender issues through the lens of ecofeminism theory.
