Advanced digital tools in landscape architecture are mostly limited to visualization and presentation of alternatives. However, they can potentially be used in different design stages. In this paper, we propose a method to approach a design problem as a multi-objective problem (MOP) and integrate advanced digital techniques into an automated landscape design framework to exploit their superior computational capabilities. We combined geographic information system (GIS) tools for mapping of the site, 3D Isovists for analyses, and a meta-heuristic method (constrained Non-dominated Sorting Genetic Algorithm-2 or NSGA-II), to search in the continuous solution space (fitness landscape). The case study was an urban park in Tehran, Iran, and the focus was on spatial-visual characteristics of the green space. The results showed that the NSGA-2 was able to solve the complex design problem with 185 trees and 66 observers. The algorithm produced a Pareto-frontier consisting of four optimal solutions that, compared to the existing state of the park, showed more than 18% and 12 % improvement according to Tree View and Building View, respectively. These results confirmed the applicability of our proposed semi-automated design framework. This study is of interest to both professional practitioners and academics of landscape architecture since it can help bridge the gap between scientific assessment and its application in real-world design studies. The proposed method can be further developed to take other design considerations into account and also has the potential to be of use in other related design fields.

Urban parks significantly enhance the urban residents' quality of life, offering spaces for recreation that positively impact physical and mental well-being. This comprehensive study, involving 400 diverse respondents, delves into urban park usage, visitor preferences, and attributes, shedding light on their crucial role in urban planning and community welfare. Demographic factors such as age, gender, religion, education, and health were analyzed, underscoring the importance of inclusive park design. Most participants frequented parks, favoring walking, biking, and motorbikes for transportation. While accessibility generally received positive feedback, some respondents faced challenges due to long travel times, hinting at potential distribution disparities. The study also explored willingness to pay for park access, revealing varying pricing opinions and aiding in sustainable park management decisions. Satisfaction levels varied across parks, with higher scores associated with diverse green spaces, well-maintained facilities, and safety measures. Preferences were influenced by factors like distance and cost. Structural diversity analysis highlighted varying degrees of diversity among parks, emphasizing the importance of diverse amenities, accessible design, and sustainable management practices. These insights offer valuable guidance for urban planners and park authorities to address community needs and foster well-being and community connection in urban spaces.

The current trend in education is to adopt a direct and efficient system that adapts to the needs of students at all levels. This approach emphasizes the importance of creating an accessible and enjoyable learning environment that integrates with the social context. The main purpose of this study is to gain a comprehensive understanding of the educational contribution of UGGps, irrespective of their level, origin, or purpose of visit, beyond the acquisssition of knowledge. The UNESCO Global Geoparks (UGGps) are recognized as educational models in the field of geosciences and sustainability due to their territorial management plan and purpose. This study examines the activities carried out in the Arouca and Estrela UGGps in Portugal, using validated questionnaires to gather feedback from students and teachers. The analysis aims to identify the strengths, challenges, and overall effectiveness of these UGGps as an alternative approach to multidisciplinary education. With a total sample of 325 students and 167 teachers, the results, from the students and teachers perspective, show a positive and valid environment for multilevel education reflected on a positive answer rate of 86% among students and 88% among teachers. As it is shown in the results, UGGps are valid territories for multilevel teaching of Earth Sciences and many other subjects. This conclusions represent a great opportunity to promote heritage protection and sustainable development education from these territories, something that, in fact, is extremely relevant in the social context in which we find ourselves.

This study investigates the adaptation of the Values-Beliefs-Norms (VBN) model and the Value-Identity-Personal norm (VIP) model into the context of ecotourism intention. Specifically focusing on Cat Tien National Park in Vietnam, the research explores the relationships between biospheric values, environmental beliefs, environmental self-identity, personal norms, and ecotourism intention. The study involves 530 Vietnamese tourists as participants. The findings reveal several significant direct effects: biospheric values positively influence environmental belief/self-identity, while environmental belief/self-identity positively impacts personal norms. Moreover, personal norms positively influence ecotourism intention. The study also uncovers the mediating role of personal norms. These results highlight the importance of values, beliefs, self-identity, and personal norms in shaping tourists' intentions toward ecotourism, supporting the VBN and VIP models. The findings provide valuable insights for policymakers and practitioners in promoting sustainable tourism practices and fostering environmentally responsible behaviors among tourists visiting Cat Tien National Park and similar ecotourism destinations.

The main purpose of this study was the development of a methodology to assess the potential impacts of forest fires on geoheritage through a systematic and practical approach. The proposed methodology was applied to the geoheritage of the Estrela UNESCO Global Geopark (UGGp) in Portugal, following a forest fire in August 2022 that affected approximately 15% of its geosites (22 out of 147). A total of 20 geosites were selected for analysis, including eight directly impacted by the fire and 12 that remained unaffected. The assessment framework integrates vulnerability and hazard factors. Vulnerability was quantified based on two primary criteria: geosites value and their educational and touristic uses. Each criterion was operationalized through defined parameters and indicators, supported by standardized guidelines for evaluation. Forest fire hazard data were obtained from the Portuguese Institute for the Conservation of Nature and Forests (ICNF). The degradation risk was calculated as a function of these two factors. The results indicate that the highest vulnerability level identified was “low,” signifying the absence of substantial loss in scientific value. However, discernible impacts on cultural, scenic and ecological values, and on educational/touristic uses were observed across most geosites. The maximum degradation risk was classified as “medium,” suggesting that the predominant granite and glacial landforms within the study area exhibit a relatively high degree of resilience to forest fire-induced damage. The findings underscore the importance of implementing targeted management strategies to mitigate the impacts of forest fires within the Estrela UGGp. Moreover, the methodology offers a transferable framework for geoheritage degradation risk assessment, which could be applied in diverse contexts to further enhance the understanding and conservation of geoheritage.

Travelers may now actively support environmental protection while having a great time on their trips thanks to the growing trend of eco-tourism. This study aims to examine, while accounting for pro-environmental behavior, the effects of digital green marketing and visitors' environmental attitudes on their willingness to return to eco-destinations. In addition, the hypothesis was investigated in this work using the structural equation model (SEM). The study's findings suggest that visitors' attitudes about the environment and digital green marketing have a positive influence on their environmental behavior. Moreover, it has been found that tourists' intentions to return are positively impacted by their ecologically conscious conduct. Studies have indicated that travelers' intentions to return to eco-destinations are significantly influenced by their pro-environmental conduct. By examining the relationship between digital green marketing initiatives, travelers' pro-environmental views and actions, tourism ecosystems, and their intention to return to eco-destinations, this study will add to the body of current work. Additionally, the study's findings will provide clear guidance to destination marketing organizations (DMOs) on how to effectively market their eco-destinations, which will motivate travelers to follow responsible travel guidelines and encourage return trips to these eco-friendly locations.

Djoudj National Bird Sanctuary, as a UNESCO natural heritage site, is a critical habitat for migratory birds along the East Atlantic Flyway (EAF). The bird habitat has undergone the dramatic variations of the Land Use and Land Cover Change (LUCC) under the influence of climate change and human activities, posing a serious threat to the survival of migratory birds along the EAF. In order to explore the spatio-temporal variations of LUCC in Djoudj National Bird Sanctuary during 1984 to 2023, this study employs multitemporal satellite image data to extract the LUCC of this heritage site and adjacent region, and comprehensively analyze the impact factors induced the variations of LUCC. Our results show that it went through two stages of the significant change in LUCC over the past 40 years. The first stage of significant change is from 1984 to 1990, when the areas of soil land and saline soil land had largely transformed into water bodies, vegetation, and wetlands. The areas of soil and saline soil land were decreased by 28.86% and 8.96%, respectively. Meanwhile, the areas of wetland, water body and vegetation increased to 30.53%, 4.92% and 2.37%, separately. The second stage of significant change in LUCC is from 2000 to 2010, while the area of vegetation (including the invasive plants) increased significantly to 54.02%, and the areas of water bodies, wetlands, and saline soil areas decreased to 6.19%, 10.37%, and 10.05% respectively. At the same time, the area of agricultural land around the heritage site rapidly increased from 13.292 km2 in 2006 to 114.2603 km2 in 2023. These significant variations of LUCC led to a decrease in the number of migratory birds, and the Djoudj National Bird Sanctuary had been listed as List of World Heritage in Danger twice by the World Heritage Committee. The major factors contributing to these significant changes in LUCC are mainly caused by human activities, such as the construction of the Diama Dam and improper use of upstream of the dam, as well as the expansion of agricultural land around the heritage site. Thus, we suggest that the heritage administrative authorities should make relevant measures to scientifically minimize the impact of human activities on ecosystem of the heritage site, and conduct regularly an integrated “space-to-ground” monitoring and assessment of water usage of the dam, controlling of invasive plants, strictly regulating the expansion of agricultural land within the heritage site and adjacent region.
