Providing demonstrable and quantifiable evidence to substantiate the value of Marine Protected Areas like National Marine Sanctuaries is important for understanding their role in the blue economy, as well as gaining management and financial support for their protection. This study employs economic contribution analysis to estimate the economic contributions of ocean recreation spending of visitors to Gray’s Reef National Marine Sanctuary (GRNMS) and the coastal Georgia region. Employing economic contribution analysis is found to be more useful in influencing stakeholder decisions, and can therefore be a useful tool in providing inputs for management decisions related to marine protected areas. This study shows that visitors to coastal Georgia spent about USD 1.4 billion on ocean recreation activities in a single year. This translates to a total economic contribution of 18,950 jobs, USD 603 million labor income, USD 938 million value added, and USD 1.8 billion output. About USD 123 million of the total visitor spending can be attributed to GRNMS, contributing 1702 total jobs, USD 54 million in total labor income, USD 84 million in total value added, and USD 159 million in total output. This study highlights the importance of coastal Georgia and GRNMS as economic drivers of the region’s economy, supporting the need for continued management and investment in the Sanctuary and its resources.

Tight lines: Algal bloom, anglers perception, and economic impact of recreational fishing – The case of lake Okeechobee, Florida
Recreational fisheries are increasingly vulnerable to environmental degradation. Understanding the dynamics of nature-based recreation and the attendant tourism economy requires an integrative modeling framework that captures the interplay of seasonality, uncertainty, and users’ response to ecological stressors. This study presents a model focusing on Lake Okeechobee—a recreational bass fishery in USA. Landuse activities surrounding the lake contribute to elevated nutrient levels, resulting in harmful algal blooms (HABs) that affect recreational activities. Using primary and secondary data and stochastic input-output model, the study quantifies tourism-related economic losses due to HABs. In 2019, recreational fishing generated about $369 million in economic output, supporting 2700 jobs and $122 million in earnings. Under less severe and extreme HAB scenarios, regional earnings could decline by 7.74% and 44.32%, respectively. These findings underscore the importance of understanding connections between environmental quality, system uncertainty, seasonality, user behavior, and economic impacts when planning for sustainable nature-based tourism.

Investigating Land Use Changes with Development of the Informal Road Networks: Case-Study in Siberianull (Ed.)While researchers of social-ecological systems acknowledge existence of formal and informal institutions affecting social-ecological governance, the role of informal sector in the land use change remains understudied. Moreover, existing studies of informal land use are focused mostly on urban areas, such as informal settlements. We argue that the remote regions would be another important area for inquiries. Informal, e.g. unobserved by official records, land use changes there are related to high-speed dynamics of resource extraction projects and location mostly in the regions of traditional land use practices of indigenous people. In particular, we focus on informal roads, which in the Arctic and Subarctic remote regions often remain understudied due to their small size, chaotic, temporal or even seasonal nature, private ownership or traditional subsistence functions. Despite their absence on official maps, they have significant social, economic and environmental impact on local, predominantly indigenous, communities. The study area: the north of Irkutsk region and Republic of Buryatia that the last decades has undergone rapid changes of traditional way of life of "old settlers", native Buryats and Evenks, collapse of the Soviet economy, development of oil and gas extractive industries and infrastructure, environmental regulations to protect the Lake Baikal and tourism development. The data was obtained in 2016-2018 at the municipal and local levels using interviews, observations, statistics and cartographic tools. As a result, we identified formal and informal elements of transportation infrastructure with common set of characteristics (e.g. time of development; purpose; present conditions; changes in location; use) and distinguished the specifics of their maintenance requirements, the forms of ownership, seasonality and local traditions. The future plans to use remotely-sensed data, coordinated visual mapping sessions, and field studies for understanding land use changes due to development of informal road networks will be discussed in the presentation.more » « less

Morrison, Amy C (Ed.)The Zika virus epidemic of 2015–16, which caused over 1 million confirmed or suspected human cases in the Caribbean and Latin America, was driven by a combination of movement of infected humans and availability of suitable habitat for mosquito species that are key disease vectors. Both human mobility and mosquito vector abundances vary seasonally, and the goal of our research was to analyze the interacting effects of disease vector densities and human movement across metapopulations on disease transmission intensity and the probability of super-spreader events. Our research uses the novel approach of combining geographical modeling of mosquito presence with network modeling of human mobility to offer a comprehensive simulation environment for Zika virus epidemics that considers a substantial number of spatial and temporal factors compared to the literature. Specifically, we tested the hypotheses that 1) regions with the highest probability of mosquito presence will have more super-spreader events during dry months, when mosquitoes are predicted to be more abundant, 2) regions reliant on tourism industries will have more super-spreader events during wet months, when they are more likely to contribute to network-level pathogen spread due to increased travel. We used the case study of Colombia, a country with a population of about 50 million people, with an annual calendar that can be partitioned into overlapping cycles of wet and dry seasons and peak tourism and off tourism seasons that drive distinct cyclical patterns of mosquito abundance and human movement. Our results show that whether the first infected human was introduced to the network during the wet versus dry season and during the tourism versus off tourism season profoundly affects the severity and trajectory of the epidemic. For example, Zika virus was first detected in Colombia in October of 2015. Had it originated in January, a dry season month with high rates of tourism, it likely could have infected up to 60% more individuals and up to 40% more super-spreader events may have occurred. In addition, popular tourism destinations such as Barranquilla and Cartagena have the highest risk of super-spreader events during the winter, whereas densely populated areas such as Medellín and Bogotá are at higher risk of sustained transmission during dry months in the summer. Our research demonstrates that public health planning and response to vector-borne disease outbreaks requires a thorough understanding of how vector and host patterns vary due to seasonality in environmental conditions and human mobility dynamics. This research also has strong implications for tourism policy and the potential response strategies in case of an emergent epidemic.more » « less

Toxic Algal Bloom Recurrence in the Era of Global Change: Lessons from the Chilean Patagonian FjordsToxic and harmful algal blooms (HABs) are a global problem affecting human health, marine ecosystems, and coastal economies, the latter through their impact on aquaculture, fisheries, and tourism. As our knowledge and the techniques to study HABs advance, so do international monitoring efforts, which have led to a large increase in the total number of reported cases. However, in addition to increased detections, environmental factors associated with global change, mainly high nutrient levels and warming temperatures, are responsible for the increased occurrence, persistence, and geographical expansion of HABs. The Chilean Patagonian fjords provide an “open-air laboratory” for the study of climate change, including its impact on the blooms of several toxic microalgal species, which, in recent years, have undergone increases in their geographical range as well as their virulence and recurrence (the species Alexandrium catenella, Pseudochattonella verruculosa, and Heterosigma akashiwo, and others of the genera Dinophysis and Pseudo-nitzschia). Here, we review the evolution of HABs in the Chilean Patagonian fjords, with a focus on the established connections between key features of HABs (expansion, recurrence, and persistence) and their interaction with current and predicted global climate-change-related factors. We conclude that large-scale climatic anomalies such as the lack of rain and heat waves, events intensified by climate change, promote the massive proliferation of these species by creating ideal conditions for their growth and persistence, as they affect water-column stratification, nutrient inputs, and reproductive rates.more » « less

Coastal communities are among the most rapidly changing, institutionally complex, and culturally diverse in the world, and they are among the most vulnerable to anthropogenic change. While being a driver of anthropogenic change, tourism can also provide socio-economic alternatives to declining natural resource-based livelihoods for coastal residents. The purpose of this study is to assess the impact of small-scale cruise tourism on coastal community resiliency in Petersburg, Alaska. Exploring these impacts through resiliency theory’s lens of exposure, sensitivity, and adaptive capacity, we employed ethnographic research methods that emphasize emic viewpoints to determine how residents see this form of tourism affecting the resiliency of valued community culture, institutions, and traditional livelihoods. Findings indicate that with purposeful engagement in niche cruise tourism involving boats with 250 passengers or less, and an active rejection of the large cruise ship industry, Petersburg exhibits increased adaptive capacity to promote the resilience of valued community institutions and heritage. This work draws needed recognition to the diversity of activities that fall under the label of cruise tourism, including the distinct implications of smaller-scale, niche cruise tourism for the resilience of coastal communities. It also highlights the need to capture emic perspectives to understand the politics of community resiliency.more » « less
