Cambodia serves as a prime example of a developing country where the local community necessitates sustained stakeholder support to foster empowerment and promote local economic development. Ecotourism and conservation are among the major issues of concern in the study of community development. This study used the main five eco-tourism areas in Cambodia as examples. It looks at the connections between eco-innovations in tourism products, community engagement, co-creation experiences, support for CBET, perceived impact likelihood outcomes, community economic benefits, environmentally responsible behavior in ecotourism sites, and biodiversity conservation. The study employed a quantitative research approach to investigate and parameterize the dynamic ecotourism components as well as to explore key factors that influence the CBET. We collected the data using a self-administered survey on 398 local eco-based tourism communities that sell services and products to tourists. We also asked for structured questionnaire items of local communities that provide tourism services to visitors in eco-tourism destination sites in 2022-2023. The SEM results showed that this study significantly impacted and confirmed all relationships among research variables, as proposed in the conceptual model. We also discuss in detail the research findings of this study.展开更多

As such, the site endures constant land development that creates rigorous growing conditions for urban vegetation. Natural resource managers at ORNL recognize that trees are an integral component of the landscape and are interested in characterizing the urban forest and their associated ecosystem services benefits. We evaluated the urban forest structure, quantified ecosystem services and benefits, and estimated economic value of resources using i-Tree Eco at ORNL. While this assessment captured over 1100 landscape trees, the ORNL Natural Resources Management for landscape vegetation can be expanded to include unmanaged landscapes, e.g. riparian areas, greenspace, and other vegetative attributes to increase ecosystem services benefits. Assigning a monetary value to urban forest benefits help to inform decisions about urban forest management, ideally on cost-benefit analysis.展开更多

The first group consists of professionals and companies in eco-sustainable businesses, such as law firms, insurance companies, investment firms, banking, technological innovation, mass media, medical research and pharmaceutical research. The second group will consist of persons engaged in organic/eco-sustainable agriculture whose crops and animal husbandry practices can be transferred successfully to Climate Change Haven regions. The present research focuses on the social and economic variables that must be taken into account to insure that each new Climate Change Haven Community becomes successfully integrated with the local population and forms a cohesive, harmonious social structure. Examples are given from the United States, France, Spain, Portugal and Italy.展开更多

During a period of one year, sandflies were collected in three different locations, where the sampled residences were located, respectively, one inside the forest, the other two, respectively at the edge of the forest and the other in a more urbanized area. These three types of ecotopes were evaluated: home, peridomicile and kennel. Four hundred and fifty-six sandflies were collected and six species belonging to five genera were identified: Migonemyia migonei, Lutzomyia longipalpis, Nyssomyia intermedia, Evandromyia sallesi, Evandromyia edwardsi and Brumptomyia wedge. The two most abundant species collected were M. migonei and L. longipalpis, contributing 70% and 18% respectively, totaling 88% of the individuals collected. The results suggested that modifications of the natural environment due to anthropic action probably resulted in changes in the composition of the sand fly population. At point (3), where spraying occurred irregularly, even representing a degraded environment, only one species was captured, M. migonei. Differently at points (1) and (2), areas located respectively in the interior and on the edge of the Atlantic Forest, a greater number of sand fly species was observed. However, after a few years, anthropic actions ceased, followed by the implementation of reforestation projects and currently the landscape is very different, showing considerable forest recovery. For this reason, ecotourism activities are increasing in the area, creating potentially dangerous conditions caused by the exposure of greater numbers of people and dogs to insect vectors. Therefore, the implementation of environmental education projects is essential. However, we suggest that the use of warning signs to be placed at the entrances to the main traffic routes, alerting tourists to the risk of infection and indicating protective measures, would be very useful.展开更多
