“…Our results suggest that visitation decisions by respondents who had recreational contact with coastal and marine environments (particularly through snorkeling) were more sensitive to environmental change than those who did not engage in these activities. This is consistent with results found by Beharry-Borg and Scarpa [21], Kosenius [44], and Hynes et al [49], who find that willingness to pay for marine quality is positively associated with recreational contact and supports the findings of numerous studies in the literature showing that underwater recreationists have strong preferences and willingness to pay for healthy reefs and diverse fish populations [21][22][23]. Importantly, poor water quality is expected to have a greater impact on snorkelers than on swimmers, as water quality affects health and has an impact on the visual aesthetic of the marine environment.…”

“…An important policy implication is that if the economic costs of improving environmental quality are prohibitive, maintaining status quo conditions might be enough to support continued tourism demand. It is important to note that this result stands in contrast to numerous monetary valuation studies that show positive WTP for improvements in coastal and marine quality [14,[21][22][23]43], and illustrates the importance of understanding both price and quantity aspects of the demand relationship. It seems clear from the literature that people are WTP higher prices for trips with improved environmental quality, but it may be the case that such improvements would not induce a change in the number of trips demanded.…”

Changes in the stated intention to return can be measured several ways.…”

Coastal and Marine Quality and Tourists’ Stated Intention to Return to Barbados

Seawater quality is critical for island and coastal communities dependent on coastal tourism. Improper management of coastal development and inland watersheds can decrease seawater quality and adversely impact marine life, human health, and economic growth. Agricultural runoff and improper sewage management compromise nearshore water quality in many coastal regions and can impact visitation decisions of tourists who are drawn to these destinations. The purpose of this paper is to understand how tourists’ decisions to revisit Barbados might be affected by changes in coastal and marine quality. We use data collected from tourists to examine how tourists’ stated willingness to return is affected by scenarios involving changes in seawater quality, beach width and coral reef health. Results reveal that return decisions are sensitive to changes in all aspects of coastal and marine quality. A reduction in seawater quality discourages tourists’ intention to return more than other environmental factors. These results are of paramount interest to destination managers, marketers and policymakers who rely on repeat visitation data to develop marketing strategies and infer future direction. This research highlights the importance of prioritizing seawater quality management to protect the coastal tourism product, especially in small island developing states (SIDS) with a high reliance on tourism income.

“…Successful conservation requires changing people's attitudes toward the focal species. For example, in sites where there is an ecotourism industry based on sea turtles, attitudes have been influenced by stressing the significance of the nonconsumptive value of these species (Cazabon-Mannette, Schuhmann, Hailey, & Horrocks, 2017;Rathnayake, 2016;Smith, Pedrini, & Ghilardi-Lopes, 2017) and stressing the importance of biological interactions that involve sea turtles (Griffin et al, 2017). Such education efforts have resulted in decreases in the number of individuals harvested, helping ensure the continued survival of these populations (Stewart, Norton, Tackes, & Mitchell, 2016).…”

Analysis of People's Perceptions of Turtle Conservation Effectiveness for the Magdalena River Turtle Podocnemis lewyana and the Colombian Slider Trachemys callirostris in Northern Colombia: An Ethnozoological Approach

The endemic species Podocnemis lewyana, the Magdalena River turtle, is listed worldwide as one of the turtle species at highest risk of extinction, and Trachemys callirostris, the Colombian slider, is the most trafficked turtle species in Colombia. An ethnozoological approach was used to analyze people's attitudes and perceptions on the effectiveness of conservation programs for these species and to identify conservation measures that would contribute to turtle population sustainability. Available statistics on turtle trade were also used as complementary information. We interviewed local residents who were exposed (n ¼ 50) and not exposed (n ¼ 50) to turtle conservation initiatives. When evaluating the two focal turtle species, we found differences in direct use between people exposed and not exposed to conservation programs, where people exposed to conservation initiatives made less direct use of these focal species. However, when other sympatric turtle species were considered, there were no significant differences in levels of turtle exploitation between people exposed and not exposed to conservation programs. Thus, successfully reducing the consumption of a focal turtle species might lead to an increased use of other local turtle species. Almost all interviewed locals were aware of turtle population declines, with the perceived most serious risk to turtle species reported being habitat loss and degradation followed by human consumption. Regarding turtle trade, we did not find significant differences between the two groups. Illegal trade levels in 2010 were 6.5 greater compared to 2016. We propose several new directions for turtle management and conservation of these species.

Economic valuation of wildlife conservation

This paper reviews concepts and methods for the economic valuation of nature in the context of wildlife conservation and questions them in light of alternative approaches based on deliberation. Economic valuations have been used to set priorities, consider opportunity costs, assess co-benefits of conservation, support the case for conservation in public awareness and advocacy, and drive novel schemes to change incentives. We discuss the foundational principles of mainstream economic valuation in terms of its assumptions about values, markets, and human behaviour; propose a list of valuation studies in relation to wildlife protection; and explain the methods used. We then review critiques of these approaches focusing on the narrow way in which economics conceives of values, and institutional, power, and equity concerns. Finally, we complement conventional approaches commonly used for wildlife valuation with two forms of deliberative valuation: deliberated preferences and deliberative democratic monetary valuation. These are discussed in terms of their potential to address the drawbacks of mainstream economics and to realise the potential of valuation in bridging conservation of nature for its own sake and its important contributions to human well-being.
