While negative impacts of tourism on environmental quality are being increasingly documented, the effects of degrading environmental quality on tourists’ choices have been largely neglected. Here we investigated the case study of Egyptian Red Sea, one of the world's most popular targets for blue tourism. We provide evidence that, in the North (Sharm El Sheikh), coral reefs experienced a progressive degradation (25–40 % from 1991 to 2023 in the most impacted touristic targets). We report multiple evidence that the loss of natural capital decreased the attractiveness of touristic areas: the shift of tourism flows towards the more pristine regions of the South (Marsa Alam) was unable to counterbalance the loss of Sharm El Sheikh. The significant decline in tourism flows (-23 %, 2009–2019) caused an estimated annual loss of ca. 1.77 billion USD (0.6 % of the Egyptian GDP in 2019). We conclude that, given the increasing demand of pristine environments as tourism target, an unsustainable ecosystem management can threaten local economies, particularly where nature integrity represents a key asset for destination choice. Policy makers should thus consider the convenience of protecting natural capital and/or carrying on ecosystem restoration interventions to recover their attractiveness and develop a sustainable blue-tourism economy.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"172 ","pages":"Article 106507"},"PeriodicalIF":3.5,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142664255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, as a first step, using choice experiments, this paper estimates the willingness to pay (WTP) for blue whale watching in relation to boat congestion and whale abundance in Loreto Bay National Park. Choice experiments for blue whale watching are scarce and allow for the identification of the amount tourists are willing to pay given the characteristics of the activity without affecting their utility. The results of this paper show that boat congestion and whale abundance are determinants of tourist utility. Tourist specialisation, age, gender, nationality, income, norm crowding, first time visitor and other nature activities are also important variables in determining their WTP. In particular, international first-time visitors who engage in fishing as a complementary activity are interested in providing an additional payment. The results suggest that whale abundance needs to be conserved, as well as the actual number of boats and the passive method of whale watching. The amount of WTP could be used to implement a voluntary economic instrument such as a fund to improve adaptive management of whale watching<strong>.</strong></div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"172 ","pages":"Article 106510"},"PeriodicalIF":3.5,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142664293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most respondents considered themselves to be informed about rules governing their fishing and there was strong support for current input and output controls, including area and seasonal closures and possession and size limits. There was less support for alternative regulations that are not currently in practice, such as annual catch or effort limits, particularly among avid fishers. There was high support for minimising illegal fishing and using penalties to ensure fishers follow regulations. Relative to infrequent participants, avid fishers had greater awareness of prosecutions for illegal fishing and were more supportive of prosecution and suspensions for illegally selling recreationally caught fish.

This study delves into the decline of Sardina pilchardus stocks, focusing on key ports such as M’diq, Al Hoceima, and Nador. Using a mixed-methods approach, it integrates face-to-face interviews with 120 respondents, including fishers, captains, and owners, alongside an analysis of fishing activity data from 2009 to 2022. The research reveals a substantial decrease in Sardina pilchardus landings, from 13,452.9 tons in 2014–687.9 tons in 2022 (-94 %), alongside a notable decline in fishing effort and the number of active purse seiners. The contribution of Sardina pilchardus to total landings and its commercial value has also diminished, though it remains significant, contributing on average 30 % to annual revenue. Socially, the study highlights an aging fishing population with an average experience of 25 years and a predominantly low level of formal education. Most fishers rely solely on their fishing income, with an average household size of 4–5 individuals. Economic analysis shows significant variation in operational costs and revenues, with modest average daily salaries for crew members. Fishermen's perceptions reveal concerns about rising operational costs, extended fishing durations, and income reduction, emphasizing the need for enhanced conservation measures and financial compensation. The findings underline the urgent need for sustainable management practices to ensure the long-term viability of the fishery and the well-being of the fishing community.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"172 ","pages":"Article 106502"},"PeriodicalIF":3.5,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142664207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study describes the patterns of biological diversity and the abiotic environment along a densely inhabited stretch of the Brazilian coastline. We examined sea surface temperature and chlorophyll-<em>a</em> concentrations among urbanized coasts, inshore, and open water zones. Locally, we considered sites under contrasting protection status (partially restrictive MPA, multiple-use MPA, and no protection areas), the impact of sedimentation, the structure of sessile (algae, corals, and other invertebrates) and fish communities (abundance and diversity). Urban coastal sites are dominated by filamentous turfs (∼55 % coverage), exhibit high sedimentation rates (mean ∼180 mg/cm²/day), and low fish diversity (mean below 9 species/60m²). Open water zones have higher benthic and fish diversity. The highest biomass of fishes (mean ∼575 g/m²) as well as native corals (mean ∼13 %) and calcareous algal turf abundance (mean ∼38 %) was observed in the Alcatrazes archipelago, which increased its no-take MPA limits recently. In an unmanaged multiple-use protected Island, reefs were dominated by the invasive sun coral <em>Tubastraea</em> spp. The expansion of this alien coral is a real threat to the regional biodiversity, and its risk should be considered in management practices, which is done in the Alcatrazes archipelago. Our analysis demonstrates that effective management of multiple-use coastal settings may need to include flexible approaches that include land-based management, which can complement MPA tools to protect and conserve biodiversity. Since the region is considered a hotspot of cumulative impacts, ecosystem quality of the Alcatrazes archipelago could be considered substantially better than expected, being a bright spot of conservation.

The Saguenay–St. Lawrence Marine Park includes 37 % of the population’s critical habitat and several of its areas of high residency. Among these areas, the mouth of the Saguenay Fjord is the one where marine traffic is the most intense. In 2017, Parks Canada implemented a regulatory slowdown measure to help reduce disturbances associated with navigation activities. This measure is effective from May to October and limits vessel speed to 15 or 20 knots, depending on the speed required to plane. Based on an initial assessment of compliance, only 14 % of whale watching excursions had a maximum speed of less than 15 knots while 26 % were between 15 and 20 knots. To improve compliance, an AIS reporting system was developed after consultations with whale watching industry representatives. These reports included statistics for individual boats and for each company’s fleet. After two years of implementation, the percentage of excursions with a maximum speed less than 15 knots was 35 % and 59 % between 15 and 20 knots.
