A Review of Whale-Watching and Whaling with Applications for the Caribbean

Whale-watching is a significant and growing tourism industry worldwide. Whaling has a long history and, although largely curtailed today, still occurs in a few countries around the world and in the Caribbean. Whaling has been labeled an incompatible activity with whale-watching because, in some cases, it reduces the number of whales available for use and changes whale behavior. Moreover, in some situations, whale-watching generates greater revenue than whaling, and whaling may detrimentally affect the larger tourism industry because of negative attitudes toward whaling by whale-watchers, other tourists, and host communities. This article examines the potential impacts of whaling on the whale-watching and tourism industries, and places these impacts in the Caribbean context. In doing so, the article outlines the history and current status of whale-watching in the Caribbean, outlines other potential constraints, and highlights the need for research about the impacts and roles of these industries. In the highly competitive global tourism industry, maintaining and nurturing a country's tourism image is critically important.     

Economic Activity Derived from Whale-Based Tourism in Vava'u,Tonga

This article reports on a study that estimated the economic activity of snorkel-with-whales tourism in the small, isolated island group of Vava'u, Tonga. This research shows that these activities generate important economic and other benefits and that these benefits grew from a relatively modest USD500,000 per year in 1999 to USD5 million per year by 2009. Data from self-reply questionnaires completed by holiday-makers who traveled by aircraft (n = 499) and yacht-based visitors (n = 52) showed that whales have become the predominant attraction for visitors to these remote islands. Interviews with tour operators (n = 10) confirmed the increasing influence of whale based activities over all tourism in the Vava'u area.     

Economic value of fish,wildlife, and recreation in Michigan's coastal wetlands

On the basis of annual expenditures by recreational participants and standard values of recreation days, as well as estimated sport and commercial harvests, the gross annual return from Michigan's 105,855 acres of coastal wetlands has been estimated. Analysis of fish, wildlife, and recreational values revealed that in 1977 these wetland areas generated an economic value of $489.69 per wetland acre, for a direct annual gross of $51.8 million. Specifically, these average return values per wetland acre/year, in descending order, are sport fishing ($286), nonconsumptive recreation ($138.24), waterfowl hunting ($31.23), trapping of furbearers ($30.44), and commercial fishing ($3.78). These gross annual return values were calculated in an effort to sensitize the general public to the diversity and possible magnitude of selected wetland functions.

MMAS in Eastern Tropical Pacific Seascape

This article is part of a special issue that provides insight into global conservation science by analyzing a 5-year, $12.5 million global marine conservation science and policy program. In this article, we summarize the development of the program in Coiba Island in the Gulf of Chiriquí Panama, and the Galapagos islands of Ecuador, both part of the Eastern Tropical Pacific Seascape. In Panama, the history of Coiba island as a federal penal colony shaped the process and outcome of the program. In the Galapagos, the unique science history of the islands and subsequent international recognition influenced the outcomes of regional marine managed areas.     

Vulnerability of Coastal Resort Cities to Mean Sea Level Rise in the Mexican Caribbean

We evaluated the potential economic impacts of increasing sea level rise (SLR) along the Mexican Caribbean where there are major gaps in our understanding of the mechanisms controlling flooding duration and frequency associated to future ecological and economic impacts. We determined the negative economic impact of SLR on infrastructure in the largest urban centers (Cancun, Isla Mujeres, Playa del Carmen, Puerto Morelos and Cozumel) in the state of Quintana Roo (Mexico) that are considered the largest tourism “hot spots” (resort cities) in the country. The tourism industry in this coastal area injects >8 billion dollars year^?1 to the Mexican economy. Our conservative economic assessment regarding the impact of SLR, under a 1?m scenario for all coastal cities is $330 million USD. Further projections for worst scenarios (SLR >2 m) show a non-linear trend where the cost of inaction can reach up to $1.4 billion USD (2?m SLR scenario) and $2.3 billion USD (3?m SLR scenario). This potential loss of infrastructure, as construction cost, is staggering and represents a robust baseline to start evaluating with more detail future impacts of climate variability and change on the Mexican Caribbean coastline.     

The Potential Economic Benefits of Coastal Ocean Observing Systems: The Southeast Atlantic Region

The Southeast Atlantic Coastal Ocean Observing System (SEACOOS) collects, manages and disseminates coastal oceanic and atmospheric observation information along the Atlantic coast of the southeastern United States. This article estimates the benefits of SEACOOS information in eleven benefit categories. Following a methodology used in similar studies of other U.S. coastal regions, we evaluate the impacts of conservative changes in economic activity in each benefit category. The annual economic benefit of SEACOOS information is $170 million (2003 $), an estimate that falls between annual benefits of $33 million for the Gulf of Maine region and $381 million for the Gulf of Mexico.     

Social Acceptability of Aquaculture Development in Coastal Areas: The Case of Two Greek Islands

This article examines the acceptance of aquaculture development by residents and visitors of two islands, Cephallonia and Ithaki, in the Ionian Sea, in western Greece. Aquaculture farms have been established recently in both islands, and processing and packaging units in Cephallonia, generating jobs for the local communities and land rents for the villages in the coastal areas near the fish cages. However, the farms and processing and packaging units entail certain negative impacts on the environment. This study reveals that aquaculture farms have found better acceptance in Ithaki, where aqua culture is a form of development suited to this remote, small, predominantly rural island. The degree of acceptability is higher for locals than for tourists, but also for islanders who do not live in the areas where the processing units are situated. Respondents who consider the pollution of the marine environment by the farms to be high, mostly locals and residents of the villages in the vicinity of the aquaculture infrastructure or the main cities in the islands, are more likely to express a negative attitude toward aquaculture and its further development.     

深中通道工程对伶仃洋水流环境的影响

伶仃洋是珠江河口东四口门入汇的喇叭状河口湾,径、潮交汇,动力复杂。利用伶仃洋河口潮流数学模型从潮位、流速、流态、动力格局方面探讨了深中通道工程建设对伶仃洋河口潮流动力环境的影响。研究结果表明:深中通道工程建设对伶仃洋潮流动力环境影响的范围和强度均以西人工岛附近为最大,锚碇水域次之,东人工岛及桥区附近相对较小;近岛、桥局部区域潮位及流场的变化比较明显,对伶仃洋滩槽总体格局影响不大。     

Vulnerability of Caribbean Island Cemeteries to Sea Level Rise and Storm Surge

The Intergovernmental Panel on Climate Change reports that rising seas by the end of this century will increase the severity of coastal flooding and erosion. The Caribbean region is home to many small islands that are vulnerable to sea level rise and storm surge. Much of the literature examining impacts of sea level rise in the Caribbean focuses on ecosystems, infrastructure, and recreation. Few studies have examined how sea level rise will impact historic and culturally important places. In an effort to address this research gap, geographic information systems and crowd-sourced, georeferenced photographs were used to build a first-of-its-kind database of 542 Caribbean small island cemeteries. Vulnerable cemeteries were then identified based upon elevation, proximity to the ocean, and the coastal profile. Over one-fifth of the cemeteries surveyed are within 100 m of the coast. The highest concentrations of vulnerable cemeteries are on flat islands such as the Cayman Islands. Yet, some mountainous islands such as Saint Martin also have potentially vulnerable cemeteries. These findings suggest that the bereaved, cemetery managers, and managers of coastal areas that have cemeteries may have additional considerations when making long-term decisions about where and how to bury the deceased.

Comparison of Beach Nourishment along the U.S. Atlantic,Great Lakes,Gulf of Mexico,and New England Shorelines

The U.S. national beach nourishment experience is summarized for the East Coast barrier islands, the Gulf of Mexico, New England, and the Great Lakes. A total of 1,305 nourishment episodes on 382 beaches are recorded at a total estimated cost of approximately $1.4 billion ($2.5 billion in 1996 dollars). In terms of both volume and costs, nourishment has been the most extensive by far on the East Coast barrier islands. Depending on the region, between 65% and 85% of all nourishment projects have a federal funding component. Annual expenditures and sand volumes for beach nourishment are increasing, especially on East Coast barriers. At present, total annual national beach nourishment costs (excluding the Pacific Coast) are on the order of $100 million per year. The cost per cubic yard of nourishment sand as expressed in 1996 dollars has remained more or less constant over time. Additionally, the volumes of sand needed for subsequent nourishment episodes on individual beaches do not decrease, despite contrary assumptions in the shoreface-profile-ofequilibrium concept that subsequent nourishment volumes should diminish. In light of the historical experience of beach nourishment identified in this study, individual state and local coastal communities should reevaluate their plans for future beach nourishment programs. The complete listing of all the data on nourished beaches from this survey is available at www.geo.duke.edu/Research/psds/psds.htm

Indicators for Evaluating the Impact of Artificial Islands on the Barcelona Coast

Artificial islands have been constructed next to large cities due to the need for extra space in highly populated areas. These emerged structures have been used by many countries as platforms for developing infrastructure (airports, harbors, highways, etc.), rebuilding ecological areas, and creating new spaces for tourism or residential areas. In this study, two state-of-the-art numerical models for wave propagation and nearshore circulation are used to simulate the effects of an emerged artificial island on the Barcelona coast. Several sea indicators (wave height, intensity and direction of currents, and mean water level) are analyzed to assess the changes likely to be induced by an artificial island. Three different situations are studied and the indicators are compared across the different tests to obtain information that can be used in the planning process of these structures. In two-meter wave conditions, the tests show that wave height is generally reduced in the sheltered area, which leads to improved safety for beach users (bathing is prohibited when wave height exceeds the two-meter threshold). However, the numerical models also reveal that velocities in the sheltered area usually decrease, which must be controlled to prevent stagnation in the bathing area.     

The Teachable Moments on Marine Mammal Tours: Watching versus Swim-With Tours

With the continuing growth of the tourism industry over recent decades, has come a change in tourist behavior from the traditional stereotypical 3-S tourist (sun, sand, sex) to an increasingly sophisticated and demanding tourist. These “new” tourists like to learn about history, nature, and wildlife, and they expect an educational component on wildlife tours. This study investigated swim-with-dolphin tours in Kaikoura, New Zealand with regard to the educational content and the overall anatomy of these tours, using data from observations on a total of 32 tours during December 2011. The resulting data were then compared with the data from Hrycik and Forestell's study, which investigated the content of questions asked by passengers on whale-watching tours in Stellwagen Bank National Marine Sanctuary. Results of the on-tour observations indicate that the surveyed tours display a structured approach to interpretation, which is customized to the specific tour anatomy of a “swim-with” tour, and varies in some parts significantly from “watch-only” tour interpretation.

Sustainability Challenges in the Geoduck Clam Fishery of British Columbia: Policy Perspectives

The geoduck clam fishery, worth approximately CDN $40 million ¹ US $ equivalence: 35 million (Bank of Canada exchange rate on February 1, 2006). in annual landed value, is British Columbia's most valuable invertebrate fishery. This fishery has been co-managed by the Department of Fisheries and Oceans (DFO) and the Underwater Harvesters Association (UHA) since 1989. Earlier input control measures such as effort regulation, seasonal closures, and licenses failed to work effectively for more than ten years, resulting in excess fishing capacity, over harvesting, poor economic returns, and unsafe fishing practices. Output control measures such as the individual vessel quota system (IVQ) have, to some extent, proven successful in improving revenues, controlling excess fishing capacity, gaining compliance with regulations, and involving fishers in the joint decision-making processes. However, there are public concerns about a common property resource at risk of being dominated by a few UHA license holders. Additionally, there are concerns about the job losses resulting from IVQ implementation, as well as distribution and equity issues. This article traces and examines the policy context for fisheries management in the British Columbia (BC) geoduck fishery, discusses the major concerns surrounding the exploitation of long lived Methuselah's clams and concludes with areas for further research in sustaining this lucrative fishery.     

Coastal Tourist Interest in Value-Added,Aquaculture-Based,Culinary Tourism Opportunities

Despite increasing focus on sustainable aquaculture investment in the U.S. coastal zones, the aquaculture industry continues to face skepticism among consumers due to perceived negative environmental impacts, and health and food safety concerns. Partnering with culinary tourism and local food promotion efforts has potential for improving public outreach about the benefits of aquaculture, especially in coastal destinations where sustainable marine aquaculture and tourism are both occurring. Culinary tourism implies that local foods reflect the local livelihood and culture, and may be important to the tourist's experience. Aquaculture is becoming increasingly valuable to coastal destinations for assuring the steady availability of local seafood to meet demand and retaining commercial fisheries as a means to differentiate themselves to tourists. This study examined the role of subjective knowledge and attitude about aquaculture, and their effect on intention to participate in value-added culinary aquaculture tourism experiences. The study found that tourists' subjective knowledge and attitude about aquaculture influenced intentions to participate in culinary aquaculture tourism. In order for farmers or tour operators to be successful in diversifying with value-added culinary aquaculture, attention needs to be paid to educating consumers, which may be possible through strategic partnerships with tourism organizations, chefs, and restaurants.     

Constructing Paradise: The Impacts of Big Tourism in the Mexican Coastal Zone

Although coastal tourism is often looked to as a way of generating foreign revenue, it can also engender a range of social and environmental impacts. From an historical perspective, this article examines the growth of Cancún in the Mexican state of Quintana Roo since the late 1960s. The article documents a range of socioeconomic and environmental impacts associated with the rise of coastal tourism, and suggests that centralized planning and the provision of physical and financial infrastructure does not prevent those impacts. The principal causes of these impacts are also described, including changes in land-usage, population, tourism markets, foreign market penetration and control, an emphasis on short-term economic gain, weak regulatory enforcement, and an overall lack of integration of coastal zone management.
