Although recreational experience segmentation is widely used in coastal tourism research, existing motivational frameworks have been developed primarily in island and protected-area destinations, leaving urban, open-access, developing-country contexts theoretically underexplored. This study addresses that gap by identifying the dimensions of recreational experience and market segments for the city of Salinas, Ecuador—an accessible, family-oriented, urban coastal destination—to advance sustainable tourism management. Using a quantitative, cross-sectional design, data were collected through a structured questionnaire administered to 385 tourists; 374 cases with complete scale responses were retained for analysis. An exploratory factor analysis (EFA) identified seven motivational dimensions: environment and sustainable recreational resources, learning and knowledge, affective well-being and creative harmony, interest and enjoyment in the experience, aquatic natural resources and wildlife, cognitive stimulation and emotional connection, and hedonic well-being. A K-means cluster analysis, validated through the elbow method (inflection at k = 3) and silhouette coefficient (0.25), revealed three distinct tourist segments: intensive recreational tourists (n = 183; 48.9%), moderate recreational tourists (n = 136; 36.4%), and passive recreational tourists (n = 55; 14.7%). Chi-square tests confirmed significant associations between clusters and sociodemographic variables including gender, marital status, and number of visits. This study offers four theoretical contributions: it reports a more detailed motivational factor structure than previously documented three- and four-factor models for coastal destinations; it proposes recreational amotivation—grounded in self-determination theory—as a candidate visitor profile that merits further theoretical and empirical validation; it advances a destination-type-sensitive motivational framework; and it provides boundary condition evidence clarifying the contextual scope of recreational experience theory. These findings offer actionable segmentation tools for destination managers seeking to differentiate and sustain coastal tourism markets. Full article

Sustainable coastal destinations offer a variety of natural and cultural activities that form a construct of motivations that influence tourist behavior regarding their willingness to return to and recommend the destination. In this sense, the present study aimed to achieve the following objectives: to identify the motivations that drive tourist demand in sustainable coastal destinations, to establish which motivations predict tourist satisfaction in coastal destinations, and to determine which motivations predict tourist loyalty in coastal destinations. There are behavioral variables to consider, such as the intention to return, willingness to recommend the destination, and propensity to speak positively about it. The study was carried out in Montañita (Ecuador), a major surfing city in Latin America with extensive potential for water sports. A total of 380 valid surveys were collected on-site for quantitative analysis. Multiple regression and exploratory factor analysis were among the methods used. The final results showed five motivational dimensions linked to tourism in coastal areas, including nature and culture, sun and sea, recreational and sporting activities, novelty, and social interaction. Among all these factors, social interactivity and novelty stood out as the elements that had the greatest impact on visitor loyalty and satisfaction, followed by the sun and beach component. The findings will serve as input for destination managers to develop sustainable management guidelines and are also a contribution to academic literature. Full article

Chrysomya megacephala is a synanthropic fly with a high potential to act as a mechanical vector of pathogenic bacteria, surpassing Musca domestica in both bacterial load and diversity. Native to Asia and Africa, it has become a cosmopolitan species, successfully adapting to a wide range of environments, including natural ecosystems. In Colombia, studies on its role as a vector are limited and have largely relied on traditional culturing methods. This study aimed to characterize the pathogenic bacterial microbiota associated with C. megacephala using 16S rRNA gene sequencing in urban, rural, and forest settings of a coastal tourist city. Flies were collected using Van Someren Rydon traps with attractants and sterile materials. Bacterial identification was performed through Oxford Nanopore MinION sequencing (Manufactured by Oxford Nanopore Technologies, Oxford, UK). A total of 49 bacterial species were identified, with urban environments showing the highest taxonomic richness. The forest environment was characterized by a highly dominant community structure, led by Vagococcus carniphilus. Notably, 20 bacterial species of public health relevance were detected, including Clostridium botulinum, Clostridium perfringens, Ignatzschineria ureiclastica, Escherichia coli, and Streptococcus agalactiae. These findings indicate that bacterial community composition varies by environment and underscore the potential role of C. megacephala as a mechanical vector, highlighting the importance of surveillance for its public health implications.

The recovery of water and other resources from urban water systems (UWSs) has long been practiced in many Mediterranean countries, but remains relatively unexplored in Croatia. In this study, the sustainable circulation processes of water, nutrients, energy, and their components in UWSs in coastal tourist areas are analyzed in order to strengthen urban systems and environmental sustainability. Dissipative structure theory is used to critically analyze the complexity and sustainability of UWSs, urban systems, and circular economy frameworks. This study is based on conceptual analysis and knowledge (experience), and the sustainability of a circular urban water system is assessed based on circular thermodynamics. This study examines the core concepts of circular urban water systems as a local resource for nutrients, water, and energy, integrating approaches that strengthen resource recovery concepts. Systemic urban climate adaptation and circular urban systems have been adopted as interrelated strategies for resilient cities, focusing on closing resource loops while building resilience to climate impacts through whole-system approaches. This framework moves beyond single solutions, connecting urban planning, energy, water, waste, and social factors to incorporate green and low-carbon developments into cities. It was established that the principle of integrated resource management lies at the heart of effective water, energy, and nutrient management in coastal urban areas, which treats entire urban life support systems as an interconnected system. Such systems increase the efficiency percentages of water, nutrient, and energy recovery while minimizing sludge volume and system entropy, thus supporting the tourism economy and low-carbon development.

Research on coastal recreational activities has grown substantially, yet studies focusing on user perceptions of these spaces—critical for optimizing tourism experiences and management—remain fragmented and underdeveloped. This study addresses this gap by examining tourist sentiment in Xiamen, a renowned coastal city in China, using social media data. Text mining tools were utilized to process the Weibo contents through text segmentation, frequency analysis and cluster analysis. The Two-way Neural Network Fusion Model Based on the BERT (TNNFMB) deep learning approach was employed using transfer learning for sentiment analysis, while the Latent Dirichlet Allocation (LDA) model was used to uncover latent thematic patterns. Sentiment polarity analysis revealed that positive comments constituted 56.47%, negative comments only 16.3%, and neutral comments 27.2%, confirming a generally positive perception of visitors’ coastal experiences. Tourists’ social media posts primarily revolve around five core themes in coastal areas: coastal waters, waterfronts, adjacent environments, culture and creativity, and reputation and expectation. The spatial and temporal changes in sentiment scores were discovered. Areas emphasizing sea–land landscapes, cultural theme reinforcement, and open public activities generally achieved high and stable sentiment scores. Natural and natural–artificial mixed coastlines experienced significant seasonal variations in sentiment. The recommendations of this study, generated from a sentiment perspective, include shaping a harmonious coastal environment by improving coastal management and support services to enhance the comfort of the tourist experience. This study advances understanding of user-centric coastal tourism dynamics, providing evidence-based tools for managers to enhance tourist experiences and spatial quality. Full article

Coastal areas are rich in diverse resources and are ideal locations for developing the tourism industry. Thus, in coastal tourist centers, the growth rate is high, although often disorganized and unsustainable. In Mexico, tourist centers have fostered poverty belts where inhabitants live in conditions of high vulnerability due to hydrometeorological and geological phenomena in regular and irregular settlements. Thus, various coastal tourist areas in Mexico have been impacted by these types of phenomena, causing deaths, a high number of victims, and significant economic losses. Previous studies have confirmed that tropical cyclones can trigger landslides resulting from intense rainfall; however, risk estimation models and their components are presented separately. This paper presents a model based on the Intergovernmental Panel on Climate Change (IPCC) framework to estimate vulnerability to tropical cyclones and landslides in the context of climate change. The integration of both disruptive phenomena and climate change was carried out in the exposure sub-index. The socioeconomic situation of the inhabitants was included in the sensitivity sub-index. Vulnerability was modeled for the near, medium, and distant future, with population growth projections for the towns of Cabo San Lucas and San José del Cabo, Mexico. Climate change associated with urban expansion will increase exposure from 121.27 to 956.74 km², while the vulnerable population is expected to increase from 133,266 to 250,386 by 2100. The model proved to be an effective tool for determining the combined vulnerability of both phenomena, allowing for the generation of strategies for decision-makers to implement actions focused on reducing vulnerability and building resilience.

The Yangtze River Delta (YRD) region has experienced rapid development in its tourism industry, establishing itself as a leading force within China’s tourism sector. However, significant regional disparities continue to hinder its sustainable development. This study adopts a mixed-methods approach to analyze the spatiotemporal evolution of domestic tourist flows and tourism industry agglomeration patterns in the region. Using city-level data from 2016 to 2022, the analysis employs a comprehensive methodology including standard deviation, coefficient of variation, standard deviation ellipse, and locational entropy. The main findings are as follows: (1) In the pre-pandemic period (2016–2019), absolute disparities in tourist flows widened, whereas relative disparities narrowed. During the pandemic (2020–2022), absolute disparities decreased, while relative disparities initially increased before contracting. (2) Tourist flows displayed a southeast–northwest gradient, with high-value areas clustered along the southeastern coast. Standard deviation ellipse analysis reveals that tourist flows were primarily distributed along the eastern coastal corridor, parallel to the coastline. Prior to the pandemic, tourism growth showed a tendency toward spatial equilibrium; however, this trend was disrupted during the pandemic, resulting in a more decentralized spatial pattern. (3) Throughout the pandemic, tourism industry concentration increased significantly in most cities. Cities with renowned scenic attractions and diversified economic structures demonstrated stronger resilience, while those heavily reliant on tourism were more vulnerable to the pandemic’s effects.

Xiamen, a rapidly developing coastal metropolis and tourist hub in southeastern China, faces air quality challenges due to its dense population and tourism reliance. This study investigates PM_2.5 sources and temporal variations during autumn 2013–2017 via chemical characterization, mass reconstruction, and receptor modeling. The Positive Matrix Factorization (PMF) model identified five sources: secondary sulfate (31%), coal/vehicle emissions (28%), industrial emissions with secondary organic aerosols (SOA, 20%), ship emissions (14%), and fugitive dust (7%). Interannual variations in source contributions highlighted impacts of anthropogenic activities, meteorology, power plant upgrades, and stricter vehicle standards. PM_2.5 declined 19% (2013–2017), driven by emission controls, while SOA surged 42% (2015–2017) due to VOC oxidation and lower temperatures. Backward trajectory and Potential Source Contribution Function (PSCF) analyses revealed significant regional transport from northern industrial zones (32% contribution) and maritime activities. Ship emissions, which have remained relatively stable over the years, underscore the need for stricter marine regulations. Fugitive dust peaked in 2015 (25.8% of PM_2.5), linked to urban construction. The findings emphasize the interplay of local emissions and regional transport in shaping PM_2.5 pollution, providing a scientific basis for targeted control strategies in coastal cities with similar socioeconomic and geographic contexts.

As a typical coastal tourist city, Sanya has experienced large-scale urbanization driven by tourism development, leading to landscape fragmentation, disorderly urban sprawl, and irrational resource utilization. These factors have intensified regional ecological risks and caused the degradation of ecosystem service functions, thereby constraining sustainable urban development. Therefore, establishing urban ecological zoning can identify the dynamic relationship between ecological conditions and urban growth, ease human-land conflicts, and promote high-quality urban development. This study employed the value equivalency method and the landscape ecological risk index method to calculate the ecosystem service value (ESV) and the ecological risk index (ERI) of Sanya City from 2000 to 2020 and to delineate ecological zones. The PLUS model was used to predict the changes in ecological zoning of Sanya City under a natural development scenario in 2030. The results demonstrate the following: (1) The ecological risk in the study area shows a distribution pattern of “high in the south and low in the north,” with low-risk areas being the dominant type, accounting for about 80% of the total area. Over time, the area of high-risk zones has shown an increasing trend, while that of low-risk zones has decreased year by year. (2) The ecosystem service value in the study area shows a distribution pattern of “high in the north and low in the south,” with a decreasing trend over time, with a cumulative reduction of 2.11 × 10⁸ ten thousand yuan from 2000 to 2020. (3) Among the four ecological zones, the ecological protection zone is the dominant type, accounting for about 50%. The increase in the ecological early warning zone is the most significant. In contrast, the ecological optimization and improvement zones show a marked decrease. The prediction results show that by 2030, the ecological early warning and ecological protection zones will increase, while the other zones will decrease. This study adopts a temporal-dynamic approach by constructing a framework that integrates historical evolution with future simulation, providing scientific evidence for building Sanya’s ecological security pattern and spatial governance. It offers practical significance for coordinating regional ecological conservation with urban development. Full article

Urban growth often surpasses the actual needs of the population, leading to inefficient land use and long-term environmental challenges. This study provides an integrated perspective on urban landscape transformation by linking socio-demographic dynamics with ecological consequences, notably vegetation loss and increased impervious surfaces. The study area is Năvodari Administrative-Territorial Unit (ATU), a coastal tourist city located along the Black Sea in Romania. By integrating geospatial datasets such as Urban Atlas and Corine Land Cover with population- and construction-related statistics, the analysis reveals a disproportionate increase in urbanized land compared to population growth. Time-series analyses based on the Normalized Difference Vegetation Index (NDVI) and Normalized Difference Built-up Index (NDBI) from 1990 to 2022 highlight significant ecological degradation, including vegetation loss and increased built-up density. The findings suggest that real estate investment and tourism-driven development play a more substantial role than demographic dynamics in shaping land use change. Understanding urban expansion as a coupled social–ecological process is essential for promoting sustainable planning and enhancing environmental resilience. While this study is focused on the coastal city of Năvodari, its insights are relevant to a broader international context, particularly for rapidly developing tourist destinations facing similar urban and ecological pressures. The findings support efforts toward more inclusive, balanced, and environmentally responsible urban development, aligning with the core principles of Sustainable Development Goal 11, particularly Target 11.3, which emphasizes sustainable urbanization and efficient land use.

Coastal cities are increasingly exposed to the risks posed by climate change, including rising sea levels, intensified storms, and coastal erosion. In this context, risk communication plays a crucial role, as it can shape public perception, promote preparedness, and influence both emergency responses and long-term mitigation strategies. This study investigated how disaster-related risks are framed in the media, focusing on the case of Naples, Italy, following a severe coastal storm surge that struck the city’s waterfront on December 2020. Using Dynamic Latent Dirichlet Allocation (DLDA), the research analyzed 297 newspaper articles published between 2020 and 2024 to examine the evolution of media narratives over time. The findings reveal four dominant patterns: (1) a prevailing economic discourse centered on financial damages and compensations, with limited references to resilience planning; (2) a temporal framing that presents the storm as a sudden, exceptional event, disconnected from historical precedents or future climate projections; (3) a lack of emphasis on the social experiences and vulnerabilities of local residents; and (4) minimal discussion of tourists’ exposure to risk, despite their presence in high-impact areas. These results highlight key limitations of media-driven risk communication and underscore the need for more inclusive, forward-looking narratives to support urban resilience and climate adaptation in coastal cities. This research offers valuable insights for urban planners, policymakers, journalists, and disaster risk reduction professionals, helping them to better align communication strategies with long-term adaptation goals and the needs of diverse urban populations.

High-density cities have obvious characteristics of compact urban spatial form and intensive land use in terms of spatial environment, and have always been a topic of academic focus. As a typical coastal historical district, the Macau Peninsula pier district (mainly the Macau Inner Harbour) has a high building density and a low average street width, forming a vertical coastline development model that directly converses with the ocean. This area is adjacent to Macau’s World Heritage Site and directly related to the Marine trade functions. The distribution pattern of cultural heritage linked by the ocean has strengthened Macau’s unique positioning as a node city on the Maritime Silk Road. This text is based on the theory of urban development, integrates spatial syntax and POI analysis techniques, and combines the theories of waterfront regeneration, high-density urban form and post-industrial urbanism to integrate and deepen the theoretical framework, and conduct a systematic study on the urban spatial characteristics of the coastal area of the Macau Peninsula. This study found that (1) Catering and shopping facilities present a dual agglomeration mechanism of “tourism-driven + commercial core”, with Avenida de Almeida Ribeiro as the main axis and radiating to the Ruins of St. Paul’s and Praça de Ponte e Horta, respectively. Historical blocks and tourist hotspots clearly guide the spatial center of gravity. (2) Residential and life service facilities are highly coupled, reflecting the spatial logic of “work-residence integration-service coordination”. The distribution of life service facilities basically overlaps with the high-density residential area, forming an obvious “living circle + community unit” structure with clear spatial boundaries. (3) Commercial and transportation facilities form a “functional axis belt” organizational structure along the main road, with the Rua das Lorchas—Rua do Almirante Sérgio axis as the skeleton, constructing a “functional transmission chain”. (4) The spatial system of the Macau Peninsula pier district has transformed from a single center to a multi-node, network-linked structure. Its internal spatial differentiation is not only constrained by traditional land use functions but is also driven by complex factors such as tourism economy, residential migration, historical protection, and infrastructure accessibility. (5) Through the analysis of space syntax, it is found that the core integration of the Macau Peninsula pier district is concentrated near Pier 16 and the northern area. The two main roads have good accessibility for motor vehicle travel, and the northern area of the Macau Peninsula pier district has good accessibility for long and short-distance walking.

This research aims to analyze the spatial and temporal distribution of residents and tourists in an urban context, assessing the risk of overtourism. To achieve this, a tourist city is conceptualized as a complex system and examined through an agent-based model (ABM), which simulates the interactions between heterogeneous agents and their environment. This computational approach enables the exploration of emergent spatial-temporal patterns and facilitates the interpretation of overtourism as a real-world experiment. The case study focuses on Santa Marta (Colombia), a well-established coastal destination currently facing potential entry into a phase of tourism decline if management remains reactive. Simulation results reveal a high risk of overtourism and illustrate the differentiated effects of two plausible management strategies at distinct spatial scales. Additionally, this study proposes a tourism intensity indicator, addressing the problem of overestimating tourism pressure in existing metrics. The proposed model offers a valuable decision-support tool for assessing impacts and designing proactive management measures in destinations experiencing rapid tourist growth across multiple spatial and temporal dimensions.

Large parks play a key role in the identity of urban public spaces and as destinations for residents’ urban walks, with the social benefits they provide being irreplaceable by other types of green spaces. This study examines the accessibility of large urban parks in Rizhao, China, focusing on spatial distribution, service equity, and optimization strategies. Using GIS-based walking route proximity analysis, the study identifies significant accessibility gaps in high-density urban areas. Rizhao is a typical coastal tourist city, selected as the study area due to its low level of urbanization and the underutilization of its natural resources. This study uses online map data to evaluate the service efficiency and supply–demand heterogeneity of large parks from multiple perspectives, proposing targeted, practical, and micro-intervention-based spatial measures based on typical case analysis. The results show that 70.52% of the population in the study area is served by park entrances within a 1500 m walking distance, indicating that a considerable portion of residents remain beyond a reasonable walking distance. In the context of urban renewal and sustainable development, this study proposes practical improvements to park accessibility, including suggestions for determining suitable locations for new large parks as a long-term goal, alongside low-cost interventions such as increasing park entrances to maximize the use of existing resources and optimizing pedestrian routes (including opening gated communities and adding crossing facilities) to improve park walking service catchment in smaller environments. This study provides insights for urban park renewal, retrofitting, and expansion, supporting accessibility measures in planning practices, and is expected to provide valuable references for urban managers and policymakers. Furthermore, the study suggests that policy adjustments are necessary to integrate green spaces into urban development more effectively, particularly in rapidly urbanizing areas. Full article

The spatial distribution of tourist attractions plays a critical role in the development of coastal cities. Qingdao, with its coastal geography, rich cultural heritage, and rapid urbanization, serves as a representative case. This study integrates POI and multi-source data, employing methods such as the average nearest neighbor index, kernel density estimation, standard deviational ellipse, and Geodetector to analyze the spatial characteristics and influencing factors of Qingdao’s tourist attractions. Additionally, path dependence theory is innovatively applied to elucidate the mechanisms of the city’s development trajectory. Both natural and social factors influence this distribution, where the resource environment forms the foundational basis, the economic development provides impetus, and the urban development orientation exerts a regulatory effect. The findings are broadly applicable to other coastal tourist cities and offer strategic insights for sustainable development in such contexts. Full article
