How the popularity of sea cucumbers is threatening coastal communities

Coastal communities are struggling with the complex social and ecological impacts of a growing global hunger for a seafood delicacy, according to a new study from the University of British Columbia.

“Soaring demand has spurred sea cucumber booms across the globe,” says lead author Mary Kaplan-Hallam, who conducted the research as a master’s student with the Institute for Resources, Environment and Sustainability (IRES) at UBC.

“For many coastal communities, sea cucumber isn’t something that was harvested in the past. Fisheries emerged rapidly. Money, buyers and fishers from outside the community flooded in. This has also increased pressure on other already overfished resources.”

Sea cucumber can sell for hundreds–sometimes thousands–of dollars a pound. The “gold rush” style impacts of high-value fisheries exacerbate longer-term trends in already vulnerable communities, such as declines in traditional fish stocks, population increases, climate change and illegal fishing.

“These boom-and-bust cycles occur across a range of resource industries,” says co-author Nathan Bennett, a postdoctoral fellow at UBC. “What makes these fisheries so tricky is that they appear rapidly and often deplete local resources just as rapidly, leaving communities with little time to recover.”

The researchers based their findings on a case study of Río Lagartos, a fishing community on Mexico’s Yucatán Peninsula. For the past 50 years, small-scale commercial fishing has been the dominant livelihood of the community.

The town’s first commercial sea cucumber permits were issued in 2013, a significant economic opportunity for fishers in the region. The leathery marine animals are a delicacy in many parts of Asia, and as stocks have depleted there, demand has rapidly depleted fisheries across the globe.

A host of new challenges emerged in Río Lagartos as the sea cucumbers attracted outside fishers, money and patrons, according to the researchers’ interviews with community members.

“Resource management, incomes, fisher health and safety, levels of social conflict and social cohesion in the community are all impacted,” says Kaplan-Hallam. “The potential financial rewards are also causing local fishers to take bigger risks as sea cucumber stocks are depleted and diving must occur further from shore, with dire health consequences.”

Unfortunately, say the authors, this isn’t an isolated situation.

“There are many examples around the world where elite global seafood markets–abalone, sea urchins, sharks–are undermining local sustainability,” says Bennett. “If we want to sustainably manage fisheries with coastal communities, we need a better understanding of how global seafood markets impact communities and how to manage these impacts quickly. Think of it like an epidemic: it requires a rapid response before it gets out of control.”

Communities and social-ecological change in the anthropocene

Check out my latest article – titled “Communities and change in the anthropocene: understanding social-ecological vulnerability and planning adaptations to multiple interacting exposures” – with Jessica Blythe, Stephen Tyler and Natalie Ban just published in Regional Environmental Change. This OPEN ACCESS article can be downloaded from here or online at REC.

P1020678

Abstract: The majority of vulnerability and adaptation scholarship, policies and programs focus exclusively on climate change or global environmental change. Yet, individuals, communities and sectors experience a broad array of multi-scalar and multi-temporal, social, political, economic and environmental changes to which they are vulnerable and must adapt. While extensive theoretical—and increasingly empirical—work suggests the need to explore multiple exposures, a clear conceptual framework which would facilitate analysis of vulnerability and adaptation to multiple interacting socioeconomic and biophysical changes is lacking. This review and synthesis paper aims to fill this gap through presenting a conceptual framework for integrating multiple exposures into vulnerability analysis and adaptation planning. To support applications of the framework and facilitate assessments and comparative analyses of community vulnerability, we develop a comprehensive typology of drivers and exposures experienced by coastal communities. Our results reveal essential elements of a pragmatic approach for local-scale vulnerability analysis and for planning appropriate adaptations within the context of multiple interacting exposures. We also identify methodologies for characterizing exposures and impacts, exploring interactions and identifying and prioritizing responses. This review focuses on coastal communities; however, we believe the framework, typology and approach will be useful for understanding vulnerability and planning adaptation to multiple exposures in various social-ecological contexts.

Ocean Grabbing: Robbing Small Scale Fishers and Coastal Communities of Marine Resources or Spaces

The following open access article on Ocean Grabbing has just been published in Marine Policy: Bennett, N. J., Govan, H., & Satterfield, T. (2015). Ocean grabbingMarine Policy57, 61–68

Dark TrawlerHighlights:

  • Ocean grabbing refers to acts of dispossession or appropriation of marine resources or spaces.
  • Ocean grabbing robs fishers and communities of use, control or access to resources, land or the sea.
  • This paper presents a framework to evaluate conservation or development initiatives for ocean grabbing.
  • Three factors, governance, human security and well-being, determine what constitutes ocean grabbing.
  • A systematic program of research into the phenomenon of ocean grabbing is proposed.

Abstract: The term “ocean grabbing” has been used to describe actions, policies or initiatives that deprive small-scale fishers of resources, dispossess vulnerable populations of coastal lands, and/or undermine historical access to areas of the sea. Rights and access to marine resources and spaces are frequently reallocated through government or private sector initiatives to achieve conservation, management or development objectives with a variety of outcomes for different sectors of society. This paper provides a definition and gives examples of reallocations of marine resources or spaces that might constitute “ocean grabbing”. It offers a tentative framework for evaluating whether marine conservation, management or development is ocean grabbing and proposes an agenda for future research. For a reallocation to be considered ocean grabbing, it must: (1) occur by means of inadequate P1020882governance, and (2) be implemented using actions that undermine human security and livelihoods, or (3) produce impacts that reduce social–ecological well-being. Future research on ocean grabbing will: document case studies, drivers and consequences; conduct spatial and historical analyses; and investigate solutions. The intent is to stimulate rigorous discussion and promote systematic inquiry into the phenomenon of ocean grabbing.

Ecologically sustainable but unjust? Negotiating equity and authority in common-pool marine resource management

A paper titled “Ecologically sustainable but unjust? Negotiating equity and authority in common-pool marine resource management” co-authored by Sarah Klain, Rachelle Beveridge and myself was just published in Ecology & Society. The article asks: a) whether natural resource management can be ecologically sustainable but unjust at the same time, and b) if distribution of harvesting rights and socio-economic benefits and inclusion in management is unfair, how might access to resources and governance institutions be re-oriented. We explore these questions through a case study of indigenous peoples’ involvement in commercial sea cucumber and geoduck fisheries on the central coast of British Columbia, Canada using Elinor Ostrom’s social-ecological systems framework and common pool resource design principles.

ABSTRACT: Under appropriate conditions, community-based fisheries management can support sound resource stewardship, with positive social and environmental outcomes. Evaluating indigenous peoples’ involvement in commercial sea cucumber and geoduck fisheries on the central coast of British Columbia, Canada, we found that the current social-ecological system configuration is relatively ecologically sustainable according to stock assessments. However, the current system also results in perceived inequities in decision-making processes, harvesting allocations, and socioeconomic benefits. As a result, local coastal resource managers envision a transformation of sea cucumber and geoduck fisheries governance and management institutions. We assessed the potential robustness of the proposed institutions using Elinor Ostrom’s common-pool resource design principles. Grounded in the region’s legal, political, and historical context, our analysis suggests that greater local involvement in these invertebrate fisheries and their management could provide more benefits to local communities than the status quo while maintaining an ecologically sustainable resource. Our research highlights the importance of explicitly addressing historical context and equity considerations in social-ecological system analyses and when renegotiating the institutions governing common-pool resources.

Marine Protected Areas and Fisheries: Bridging the Divide

A new open access article titled “Marine Protected Areas and Fisheries: Bridging the Divide” has just been published online here. In this article, my co-authors and I explore lessons for effectively bridging the divide between biodiversity conservation and fisheries sustainability goals using marine protected areas through drawing on 8 case studies from around the world.Map of MPA sites

Abstract: Long-term and well-managed marine protected areas (MPAs) can, under the right circumstances, contribute to biodiversity conservation and fisheries management, thus contributing to food security and sustainable livelihoods. This article emphasizes (1) the potential utility of MPAs as a fisheries management tool, (2) the costs and benefits of MPAs for fishing communities, and (3) the foundations of good governance and management processes for creating effective MPAs with a dual fisheries and conservation mandate. This article highlights case studies from numerous regions of the world that demonstrate practical and often successful solutions in bridging the divide between MPA management and fisheries sustainability, with a focus on small-scale coastal fisheries in order to emphasize lessons learned. To be an effective fisheries management tool, MPAs should be embedded in broader fisheries management and conservation plans. MPAs are unlikely to generate benefits if implemented in isolation. The spatial and temporal distribution of benefits and costs needs to be taken into account since proximal fishery-dependent communities may experience higher fishing costs over the short and long-term while the fisheries benefits from MPAs may only accrue over the long-term. Key lessons for effectively bridging the divide between biodiversity conservation and fisheries sustainability goals in the context of MPAs include: creating spaces and processes for engagement, incorporating fisheries in MPA design and MPAs into fisheries management, engaging fishers in management, recognizing rights and tenure, coordinating between agencies and clarifying roles, combining no-take-areas with other fisheries management actions, addressing the balance of costs and benefits to fishers, making a long-term commitment, creating a collaborative network of stakeholders, taking multiple pressures into account, managing adaptively, recognizing and addressing trade-offs, and matching good governance with effective management and enforcement.

The capacity to adapt?: communities in a changing climate, environment, and economy on the northern Andaman coast of Thailand

The following article was just published:

P1010346Abstract: The health and productivity of marine ecosystems, habitats, and fisheries are deteriorating on the Andaman coast of Thailand. Because of their high dependence on natural resources and proximity to the ocean, coastal communities are particularly vulnerable to climate-induced changes in the marine environment. These communities must also adapt to the impacts of management interventions and conservation initiatives, including marine protected areas, which have livelihood implications. Further, communities on the Andaman coast are also experiencing a range of new economic opportunities associated in particular with tourism and agriculture. These complex and ongoing changes require integrated assessment of, and deliberate planning to increase, the adaptive capacity of communities so that they may respond to: (1) environmental degradation and fisheries declines through effective management interventions or conservation initiatives, (2) new economic opportunities to reduce dependence on fisheries, and (3) the increasing impacts of climate change. Our results are from a mixed methods study, which used surveys and interviews to examine multiple dimensions of the adaptive capacity of seven island communities near marine protected areas on the Andaman coast of Thailand. Results show that communities had low adaptive capacity with respect to environmental degradation and fisheries declines, and to management and conservation interventions, as well as uneven levels of adaptive capacity to economic opportunities. Though communities and households were experiencing the impacts of climate change, especially storm events, changing seasons and weather patterns, and erosion, they were reactinKo Sin Hi Pierg to these changes with limited knowledge of climate change pe se. We recommend interventions, in the form of policies, programs, and actions, at multiple scales for increasing the adaptive capacity of Thailand’s coastal communities to change. The analytical and methodological approach used for examining adaptive capacity could be easily modified and applied to other contexts and locales.

Vulnerability to multiple stressors in coastal communities: A study of the Andaman Coast of Thailand

The following article has been published online.

Bennett, N., Dearden, P., & Peredo, A.M. (2014-online). “Vulnerability to multiple stressors in coastal communities: A study of the Andaman Coast of ThailandClimate and Development

Abstract: Vulnerability and adaptation to climate change have become a dominant theme in development and conservation research and work. Yet coastal communities are facing a wider array of different stressors that affect the sustainability of natural resources and the adaptive capacity of local residents. The ability of communities and households to adapt is influenced by the nature, number, and magnitude of the changes with which they have to contend. In this paper, we present the range of 36 socio-economic (i.e. economic, social, governance and conflict) and biophysical (i.e. climate change and other environmental) stressors that emerged from qualitative interviews in seven coastal communities on the Andaman coast of Thailand. These stressors were then integrated into a quantitative survey of 237 households wherein participants were asked to rate the level of impact of these stressors on household livelihoods. Ratings showed that economic and some climate change stressors – extreme Figure 1 - Vulnerability as a Funtion of E, S, and AC finalweather events and changes in rainfall patterns and seasons – were scored higher than other stressors. The paper also examines the relationships between community and various individual and household characteristics – such as gender, age, livelihoods, levels of social capital, and socio-economic status – and the perceived level of impacts of various stressors on household livelihoods. Overall, community and livelihoods had the most differentiated impacts on perceptions of stressors but few other prominent patterns emerged. In conclusion, this paper discusses the implications of the results for current climate change vulnerability and adaptation policy and practice in Thailand and elsewhere.
