This study uses a hedonic property price method to evaluate the effects of salt marshes on residential property values in the Eastern Shore of Virginia. Contrary to findings from the wetland literature, results show an insignificant relationship between proximity to salt marsh and residential property values. In contrast, results show a statistically significant increase in property values with increasing proportions of salt marsh within 250 to 500 meters of the parcel. Furthermore, the increase in value is found to be larger for proportions of preserved relative to non-preserved salt marsh in this proximity of the home. The findings of this study can contribute to understanding the spatial patterns for housing premiums stemming from salt marshes. The information can be used to guide coastal management agencies on how to conserve salt marshes in a way that promotes residential property values.","PeriodicalId":50995,"journal":{"name":"Coastal Management","volume":"49 1","pages":"662 - 681"},"PeriodicalIF":2.5,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46660272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of them get employment, food security, and access to better health care through fishing activities. However, the fishing industry has been saddled with many challenges in recent times, which has led to low landings. This study aimed to assess the causes and effects of the decline in fish landings on the livelihood of coastal communities in the Central Region of Ghana. The systematic sampling technique was used to randomly select 200 households from four communities. A questionnaire was designed to elicit information from fisherfolk based on Likert scale estimation. In addition, time-series data of fish landings and imports for 51 years (1976–2017) was used in the analysis. The results from the study indicate that fish landings are declining, and this is affecting the income levels of fisherfolk. However, the impact of income decline on the female fisherfolk is lower as compared to their male counterparts. To mitigate against dwindling incomes, the fisherfolk have adopted livelihood diversification coping strategies. The key livelihood options identified in the communities are masonry, trading, and commercial driving. The fisherfolk mentioned overfishing, pollution, use of smaller mesh size nets, and unapproved methods of fishing as drivers of decline in fish landings. This study recommends that mandated institutions with oversight responsibilities in the fishing industry should be strengthened to enable them to conduct their functions effectively, so, they halt the decline in fish catch.","PeriodicalId":50995,"journal":{"name":"Coastal Management","volume":"49 1","pages":"617 - 635"},"PeriodicalIF":2.5,"publicationDate":"2021-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42029990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The production of the “Draft Exploitation Regulations” has been a priority theme in recent International Seabed Authority (ISA) sessions. Although discussion in reducing environmental impacts has been central to the progressive instrument, some liability gaps and approaches to close such gaps have not come up with desirable solutions. Against this background, the paper underscores the need for an Environmental Compensation Fund (the Fund) to bridge these gaps under the DSM regime. The paper argues that the three provisions about the Fund envisaged in the Draft Exploitation Regulations fall short of adequate deliberation and operational details. To bridge up the liability gaps, some critical issues in operating the Fund need to be carefully considered regarding the establishment, purpose, contributions, and claims for compensation. The paper suggests that the ISA may take the key elements of existing compensation funds, inter alia, the IOPC Funds to improve the operation and function of this Fund.","PeriodicalId":50995,"journal":{"name":"Coastal Management","volume":"49 1","pages":"557 - 574"},"PeriodicalIF":2.5,"publicationDate":"2021-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44293099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This puts pressure on local and regional decision makers to develop strategic frameworks for prioritizing, permitting and funding such projects. However, no systematic evaluation tools exist for the full range of these innovative designs. We build on the literature to develop an evaluation framework that synthesizes two different approaches to categorize these proposals and provide insight for coastal managers and decision makers. We apply this framework to physical projects that address sea level rise in their design around the San Francisco Bay Area, a leading region in sea level rise adaptation. We find that these projects demonstrate a shift toward more habitat-focused strategies, which likely marks the beginning of a larger transformation of the coastal zone. According to our five-part evaluation tool, we also find that the projects’ scores have improved over time, indicating that state agency work may be helping communities implement more flexible adaptation initiatives. Despite these positive signs, we also find that none of the projects achieved high marks in all five of the evaluation criteria. This finding indicates that there is a critical need for improvement in physical planning for adaptation to higher sea levels and associated impacts. Most importantly, we find that an evaluation framework such as the one used here can provide critical insights into the likely risks and benefits of proposed adaptation projects and their long-term implications for coastal zones.","PeriodicalId":50995,"journal":{"name":"Coastal Management","volume":"49 1","pages":"636 - 661"},"PeriodicalIF":2.5,"publicationDate":"2021-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41833220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The potential for drowning or rescue depends on a combination of physical and social factors, and this is the first study to examine the relationship amongst the presence and location of rips, beach user intentions and behavior, and the hazard level identified by the lifeguards. Results of a survey administered in the summer of 2019 at Cavendish Beach and Brackley Beaches along the north shore of Prince Edward Island (PEI), Canada, suggests that beach user intention and perception of the rip current hazard may not accurately reflect their actions. Despite being aware of beach hazards, most beach users and in particular the tourists to the area, did not observe beach warnings. Their activity on the beach also appears to be influenced by the design of the beach access and the presence of other beach users. Respondents who could not recall the hazard level defined by beach flags and signs on the boardwalk tended to sit further away from the access point and lifeguards. Most of the respondents were tourists who were at a higher risk of needing rescue or drowning caused by rip currents due to their lack of rip knowledge and familiarity with those beaches. It is argued that the potential for drownings and rescues can be mitigated through changes in the design of the beach access and the distribution of lifeguard resources, but further research into the correspondence of beach user perception, lifesaving strategies and rip currents is required.","PeriodicalId":50995,"journal":{"name":"Coastal Management","volume":"49 1","pages":"598 - 616"},"PeriodicalIF":2.5,"publicationDate":"2021-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48188283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Laschever","doi":"10.1080/08920753.2021.1956853","DOIUrl":"https://doi.org/10.1080/08920753.2021.1956853","url":null,"abstract":"This special issue of Coastal Management Journal is dedicated to Professor Benjamin Woods Labaree—one of the Sea’s Renaissance Men. The term “Renaissance” most commonly applies to the 14th century humanistic revival of classical art, architecture, literature, and learning that originated in Italy and over the next several centuries spread throughout Europe.1 When applied to an individual, a Renaissance man or woman, is “a person of broad talents and expertise” (think Michelangelo), in particular, “one straddling both humanist and technological concerns” (think Leonardo da Vinci).2 Such an individual is Professor Labaree. Labaree’s contributions to the maritime field began early, as a graduate student. Someone close to the Professor recounts, he then “debunked a previous theory about how the Greeks rowed their warships to overcome the currents through the Bosporus Straits into the Black Sea to establish trade.” Labaree realized the Greeks would not have used warships for trade and demonstrated using then-contemporary nautical almanac records to establish current speeds that under certain current and wind conditions, the Greeks’ merchant ships could make the passage.3 From 1962, when he published Patriots and Partisans through his and his co-authors’ 1998 treatise America and the sea: a maritime history, Labaree illuminated this country’s interwoven sea connections. In 1974, he became the Frank C. Munson Institute of American Maritime History’s Director where, in 1996, he co-led the National Endowment of the Humanities Summer Institute on America and the Sea. Over these two decades, he received numerous awards, including one from the North American Society for Oceanic History.4 “Renaissance” also connotes “a resurgence of excitement or interest in something.” In the 1970s, the world’s interest and excitement in the ocean and its resources surged. Internationally, nations convened under the United Nations’ auspices to negotiate a law of the sea treaty. At home, the U.S. enacted legislation to manage our fisheries and heavily used coastal zone. Riding this cresting tide, Labaree’s scholarship pivoted to all facets of the nation’s relationship to the sea by founding the Williams College-Mystic Seaport Program in Maritime Studies. At the seaport, he assembled scholars in maritime history, literature, policy, and science. Each semester, lucky students from many undergraduate institutions sat around the table absorbing tales of and lessons from the sea. In 2019, the National Maritime Historical Society awarded Williams-Mystic its Walter Cronkite Award for Excellence in Maritime Education. In bestowing the award, Burchenal Green—the Society’s President–praised the program “as the only undergraduate studies program examining the history, literature, policy and science of the sea, resulting in several thousand informed alumni prepared for societal leadership with a balanced understanding","PeriodicalId":50995,"journal":{"name":"Coastal Management","volume":"49 1","pages":"555 - 556"},"PeriodicalIF":2.5,"publicationDate":"2021-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46136245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An interactive visualization (I-Vis) tool “ElleVis,” developed by (Otinpong 2013), shows the effects of different water levels on the flora and fauna living in and around the lake. An experimental design was used in which 40 stakeholders were randomly assigned to a presentation of this information using I-Vis or a non-interactive paper form of the visualization (NI-Vis). While stakeholders in both groups significantly improved their understanding of information, stakeholders presented with information using I-Vis made a statistically significant greater gain in understanding than those presented information using NI-Vis (t(38)=2.663, p<.05). Semi-structured discussions with participants confirmed the importance stakeholders placed on the interactive nature of the visualizations.

Analysis was conducted through a multi-method approach, triangulating qualitative and quantitative results. Results show the importance of the attachment to flamingos in local landscapes. Knowledge on flamingo ecology was relatively high and participants perceived some of the regional management options to be unfavorable for flamingos. Participants identified threats to the species and expressed concern for the future of the flamingos, challenging the legitimacy of some landscape management decisions and planning policies. This research demonstrates the role of flagship species in stimulating reflection on landscape management, addressing both the ecological and human dimensions.

However, the same mineral resources that deep sea mining actors are keen to exploit in the Area, are also available within zones falling under the exclusive jurisdiction of coastal states. So even if strict rules and precise standards would be enforced with regard to seabed mining operations in the Area, similar activities within a coastal state’s national jurisdiction remain unchecked by international law. Therefore, the question can be raised whether this might lead to substandard exploitation of the minerals of the seabed without adequate supervision? This article tests this assumption in a detailed case study of the relevant legislation of the Cook Islands, comprising the 2017 Marae Moana Act and the 2019 Cook Islands Seabed Minerals Act. Following a concise analysis of the competences of coastal states on their continental shelf, the domestic laws of the Cook Islands are critically compared with the international legal framework governing the Area, to assess whether they contain equivalent rules, mechanisms and safeguards.","PeriodicalId":50995,"journal":{"name":"Coastal Management","volume":"49 1","pages":"413 - 430"},"PeriodicalIF":2.5,"publicationDate":"2021-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/08920753.2021.1928459","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48915535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This gap has largely been addressed using one-way science communication tools such as publications and conference presentations. While these tools can be designed and delivered effectively, mounting evidence suggests two-way communication builds more trust, enhances engagement, and may lead to more active use of scientific information in decision-making. The National Oceanic and Atmospheric Administration (NOAA) Western Regional Collaboration Team’s West Watch webinar is a one-way communication tool that shares information about climate, weather, and ocean condition anomalies to an internal audience of NOAA experts and key partners. NOAA is interested in expanding this tool to improve information accessibility and use by communities of interest that NOAA serves. This research uses a mixed-methods approach to evaluate how West Watch could change to function as a two-way communication tool, facilitating bilateral information movement between research presenters and the audience.
