Influence of interpretation on conservation intentions of whale tourists

The concept of interpretation denotes on-site education while people engage in a guided nature-based activity. The literature suggests that interpretation influences conservation intentions but does not reveal whether the effect is constituted by interpretation or by other aspects of the guided activity. This study examined the effect of interpretation on conservation intentions on top of a wildlife viewing tour without interpretation, and differentiated among interpretation contents. In a field experiment among whale watchers, four interpretation conditions were implemented: (1) no interpretation (control group), (2) knowledge content, (3) responsibility content, and (4) emotion content. Whale conservation intentions were measured before and after the whale watching experience. The results indicate that interpretation has an effect on whale conservation intentions. The effect of emotion interpretation was larger than were the effects of knowledge interpretation and responsibility interpretation. Incorporating emotional messages, then, could contribute to successful interpretation in terms of promoting conservation among tourists.     

Proximity and animal welfare in the context of tourist interactions with habituated dolphins

The long-term sustainability of wildlife tourism depends on integrating visitor demands with resource management, requiring an understanding of tourist motivation. Managing the conflict between access to the animals and welfare, however, may diminish the experience for tourists. This paper identifies trade-offs tourists are willing to make between access and animal welfare, associated with feeding habituated bottlenose dolphins (Tursiops sp.) in Monkey Mia, Western Australia. Using a choice modelling technique, we were able to determine monetary values of visitor experiences. Compared to the current guaranteed interaction with dolphins (and a daily resort entrance fee), respondents were willing to pay significantly higher hypothetical entrance fees to avoid a decrease in proximity to, or probability of, the dolphin interaction. However, negative impacts on dolphin welfare had a negative impact on visitor utility. Over 80% of visitors (n = 244) accepted management regulations resulting in decreased time with and proximity to dolphins, if those addressed welfare concerns and were communicated clearly. Thus, while visitors placed the greatest value on the proximity and predictability, they were willing to trade off these aspects if they improved dolphin welfare. We provide management suggestions based on these results.     

A rapid assessment of wildlife tourism risk posed to cetaceans in Asia

Dolphin-watching tourism is growing globally. In developing countries, the typically low environmental awareness of operators and poorly enforced or non-existent regulations exacerbate risks to wildlife. Ecological indicators like behavioural responses are useful to assess wildlife tourism, but obtaining such data is slow and expensive. We modified the Driver–Pressure–State–Impact–Response (DPSIR) framework to rapidly assess the risk of dolphin-watching tourism harming, displacing or causing local extinction to dolphin populations, using human dimension data to complement limited ecological data. We assessed industries at seven dolphin-watching sites in six countries in Asia: Cambodia, India, Indonesia, Malaysia, Thailand, and the Philippines. All sites have reached or almost reached financial saturation except Cambodia and Malaysia. We find high risk to dolphins at the sites in India and Indonesia and intermediate risk at the site in Cambodia. Pending more ecological data, the risk at Thailand, the Philippines, and Malaysian sites might be low. Our analysis also indicates site-specific conservation recommendations for Driver, Pressure and Response. We suggest that the DPSIR framework is useful to assess the risk of a wildlife watching industry, even when the impact is uncertain due to insufficient ecological data.

Why is contemporary China still courting concubines? Exploring the reasons for Chinese audiences’ fascination with concubines’ infighting in television dramas

ABSTRACT

This note reports the results of a systematic exploration and evaluation of the reasons underlying the very high popularity among Chinese audiences of a particular television genre featuring infighting between concubines in ancient imperial courts. Self-report questionnaires were completed by 263 respondents to assess the value they perceived to earn from watching this type of drama. Factor analysis identified five categories of experiential value yielded from watching this genre, covering dimensions related to its exquisite visual and audio effects, intriguing plots, and aroused contemplations. Linear regression showed that experiential value positively predicted audience satisfaction with this type of drama and audience satisfaction affected their choice to make it a future leisure activity, despite the potential ban of this genre by the Chinese authorities. The findings suggest that Chinese audiences’ infatuation with dramas featuring concubine infighting expresses a dichotomy of both reflection and inflection of the realities of contemporary social and cultural dynamics, thereby articulating the unique functions of leisure in facilitating this social process.     

Reducing risky interactions between tourists and free-ranging dolphins (Tursiops sp.) in an artificial feeding program at Monkey Mia, Western Australia

We studied interactions between tourists and free-ranging bottlenose dolphins in an artificial feeding program at Monkey Mia, Australia. We used logistic regression to identify factors that contributed to the incidence of “risky” (potentially injurious) interactions between tourists and dolphins. Rates of dolphin-to-tourist risky interactions were heightened with longer waiting times before dolphins were fed. We documented differences among provisioned dolphins in their proclivity to engage in risky interactions; however, it was more likely for risky interactions to be initiated by tourists. Our findings suggest several readily implemented management strategies to reduce incidence of risky interactions. Long-term monitoring of tourism based on artificial feeding is essential to identify and rectify detrimental effects of provisioning on dolphins, to ensure the safety and welfare of dolphins and tourists, and to promote sustainability of this potentially harmful tourist activity.     

Using multiple indicators to evaluate the sustainability of dolphin-based wildlife tourism in rural India

Abstract

Assessing wildlife tourism sustainability in developing countries is crucial, but few studies analyse the sustainability of dolphin-based wildlife tourism in this context. We measure multiple indicators within the human dimensions of wildlife tourism, including tourist visitation numbers, satisfaction, preferences, perceptions, background and specialisation, to ascertain the extent to which the dolphin-watching industry at Chilika Lagoon, in rural India might be considered sustainable. Our methods included participant observation, tourist surveys, and the use of secondary data on visitation over 10 years. We found that the growth rate of tourist visitation over 10 years was beginning to decline. Tourists were mostly inexperienced, and dissatisfied with their dolphin-watching experience. Tourist preferences and perceptions showed useful insights and shortcomings in the way in which the industry was being conducted and managed, and reflected the expectations of non-specialist visitors. Our study highlights drawbacks in the way that wildlife tourism is managed in a rural, developing world context, which draws the sustainability of the dolphin-watching industry in Chilika into question. Future development of an early warning system that addresses combined governance or managerial, social, economic and ecological indicators, and an integrated management plan for conservation and wildlife tourism could contribute to the sustainable management of such industries.
