The impact of climate change on prawn postlarvae fishing in coastal Bangladesh: Socioeconomic and ecological perspectives

In Bangladesh, prawn (Macrobrachium rosenbergii) farming remains dependent on the capture of wild postlarvae as hatchery production is still inadequate. However, prawn postlarvae fishing has been accompanied by concerns over recent climate change. Different climatic variables including cyclone, salinity, sea level rise, water temperature, flood, rainfall, and drought have had adverse effects on coastal ecosystem, thus determining a decline in the availability of prawn postlarvae and thereby catch. The households of postlarvae fishers also face a variety of socioeconomic constraints due to climate change. Considering extreme vulnerability to the effects of climate change, an integrated approach needs to be introduced to cope with the challenges.     

Confronting coastal poverty: Building sustainable coastal livelihoods in South Africa

This is the second of two articles exploring coastal management in South Africa. It focuses on the adoption of the Sustainable Livelihoods approach that has underpinned recent policy implementation efforts. This approach complements prevailing coastal management thinking and practice by focusing attention on the strategies that poor people use to access coastal resources, mediated by governance institutions and social relations, in the pursuit of desired livelihood outcomes. South Africa's efforts to adopt this approach help to better understand coastal livelihood opportunities and challenges, identify priority interventions for improving livelihood prospects, and reveal imperatives for building sustainable coastal livelihoods.     

Improving livelihoods in fishing communities of West Sumatra: More than just boats and machines

Despite a raft of livelihood programs designed to help Indonesian small-scale fishers there are concerns that the needs of the poor are still not being addressed. This study examines this concern through a two-pronged approach. Firstly, through a broad-scale series of interviews with fishers, community leaders and government employees in 25 fishing villages in the province of West Sumatra to identify which sectors of the fishing industry the poor operate in and the types of livelihood initiatives targeted at helping them. Secondly, by using three case studies of livelihood development projects and identifying the social, economic and institutional lessons learned that point both to best and worst practice. Three groups of poor fishers were identified; a large group of non-boat owning “labourers”, a group of “small-scale boat owners” and a small group of “processors and sellers”. Empowerment programs by the Department for Fisheries between 2005 and 2009 emphasised improving physical capital through providing fishing gear, motorisation and processing equipment. These initiatives could potentially help small-boat owners but would not benefit non-boat owning labourers. The new livelihood improvement programme GPEMP had non-fishing alternative livelihoods that could help labourers, but still demonstrated an ongoing bias towards physical capital interventions. The three case studies demonstrated that aspects of leadership, trust, advocacy, administration, accountability and ongoing institutional support are key elements of empowering coastal communities towards livelihood improvement. Human and social capital components need prioritisation in future poverty alleviation policy and programs in Indonesia, particularly for the large marginalised group of labourers.     

An analysis of livelihood projects and programs for fishing communities in the Philippines

Over the last 30 years, a range of different livelihoods have been provided and implemented in fishing and coastal communities in the Philippine with mixed success and sustainability by the fisher and household. This paper reports on an analysis of livelihood projects for fishing communities and households implemented in the Philippines and the identification of lessons learned and factors which can lead to an improved success and sustainability rate for livelihood projects and programs. The analysis identified primary factors that are critical to improving the success and sustainability rate of livelihood interventions.     

Coping with disaster: Rehabilitating coastal livelihoods and communities

This paper examines lessons from past approaches to natural disasters, as well as early lessons from the post-2004 Asian tsunami rehabilitation, to draw out general principles for rehabilitating livelihoods in poor coastal communities. We contend that avoiding the mistakes of the past requires: (1) a framework for understanding the diversity of coastal people's livelihood strategies and the sources of their vulnerability, (2) a process for designing interventions that build on this understanding in order to strengthen and revitalize coastal communities, including a means of assessing and selecting the most promising livelihood options, and (3) a focus on the longer-term challenge of building future resilience and sustainability in the communities by addressing the root causes of vulnerability.     

Fishery livelihoods and (non-)compliance with fishery regulations—A case study in Ca Mau Province,Mekong Delta,Viet Nam

Fishery in Ca Mau, Viet Nam’s most southern province in the Mekong Delta, plays locally an important role for human nutrition and has great potentials for export earnings. The overexploitation of inshore fishing resources is a major problem in Viet Nam’s coastal areas along the Mekong Delta. As a result, the Catch per Unit of Effort of small-scale fishing enterprises has decreased, undermining the sustainability of livelihoods of fishing families. The paper focuses on livelihoods’ strategies and diversification in the context of overexploitation and exhaustion of near-shore resources in relation to fishery policies. The results show that overexploitation is unavoidable in near-shore waters because of the lack of enforcement of fishery regulations for offshore vessels and the limitation of alternative sources of income and opportunities for livelihood diversification for small-scale fishers. The present policies to prevent overexploitation need to be reconciled with livelihood sustainability and fishery management, resource conservation and socio-economic goals     

Aquaculture and the poor-Is the culture of high-value fish a viable livelihood option for the poor?

This study evaluates the role of high-value fish culture in the livelihoods of coastal households in southern Thailand. The study shows that grouper culture, promoted as an alternative to destructive fishing practices, can make a substantial contribution to household incomes. However, fishing and aquaculture play contrasting roles in the livelihoods of coastal fishers and should be considered as complementary rather than alternative occupations. The study found that poorer households can benefit significantly from raising grouper in cages if certain conditions are met, including access to credit and the substitution of financial for natural capital.     

Livelihood diversity and dynamism in Timor-Leste; insights for coastal resource governance and livelihood development

Coastal communities within small island developing states are typically highly dependent on fisheries and other natural resource-based livelihoods. However, specialisation as a ‘fisher’ is rare compared to diverse livelihoods that can be adapted as opportunities and challenges emerge. Understanding this dynamic “livelihood landscape” is important for improving governance and livelihood opportunities associated with natural resources. Using data from 495 households across 15 communities on Atauro Island, Timor-Leste, this study evaluates the importance of fisheries within a suite of livelihoods; the correlation of livelihoods structure with wellbeing; and the spatial and temporal variation of those livelihoods. Activities linked to primary production were nominated by 67% of households as their primary livelihood, 41% fished, and of those 54% considered fishing their primary livelihood. Almost all households (95%) owned livestock, and even respondents who considered themselves ‘fishers’ ranked livestock disease, rather than fisheries related concerns, as their most critical livelihood challenge. Engagement in fishing varied by location and time of year. Communities in more protected locales fished throughout the year, and had less diverse livelihoods. This study highlights that interventions focused on self-identified ‘fishers’ would only engage a fraction of the population that derive benefit from fisheries resources, would likely overlook the most prevalent challenges fishers face, and would focus on those with relatively high food security and income. Measures of wellbeing were better explained by geography and socio-cultural settings, rather than dominant income sources. The results emphasise the value of cross-sector development interventions informed by contextualised analysis of livelihoods and wellbeing outcomes.     

Coastal livelihood vulnerability to marine resource degradation: A review of the Indonesian national coastal and marine policy framework

In rapidly developing countries, where large sections of the population are highly dependent on marine resources, coastal livelihoods are vulnerable to sudden shocks and long-term change. National policy can attempt to mitigate this vulnerability within a multi-level framework by addressing the three aspects of vulnerability (exposure, sensitivity, adaptive capacity) through well-documented interventions. This article reviews the Indonesian policy framework for coastal and marine policy interventions that either directly or indirectly address different dimensions of coastal livelihood vulnerability. The findings show that the policy environment for addressing coastal livelihood vulnerability is heavily based on developing adaptive capacity and to a certain extent sensitivity without adequately addressing exposure, the initial cause of vulnerability. In addition, the complexities and inconsistencies within the Indonesian governmental structures, as well as more general issues of funding gaps and poor coordination, mean that policies created at national level rarely filter down to provide the intended benefits to coastal communities. It is recommended that practitioners and policymakers engage in a more cohesive and balanced approach to addressing livelihood vulnerability in coastal management by focusing more on the causes of the disease, exposure, rather than healing just the symptoms.     

The evolution of coastal management in South Africa: Why blood is thicker than water

This is the first of two articles exploring coastal management in South Africa. Decades of coastal management effort culminated in a Cabinet-approved coastal policy in December 1999. Based on a Government–civil society partnership, the policy aims to promote sustainable coastal development through integrated coastal management. It represents a marked shift from an earlier approach that virtually ignored justice, democracy and poverty. In recent years, attention has focused on empowering poor coastal communities to build sustainable livelihoods. This paper traces the evolution of coastal management in South Africa, and reflects on the challenges of fostering coastal sustainability. The following article explores the sustainable coastal livelihoods approach in more detail.     

Social capital, community based management, and fishers’ livelihood in Bangladesh

This paper examines the impact of Community Based Fisheries Management (CBFM) on fishing households’ welfare in Bangladesh. It analyses how the various types of livelihood assets contribute to fishers’ household incomes. The study found that fishers in CBFM project areas have improved their access to different assets including social, human, physical, financial and natural capitals. The regression results show that social capital contributed significantly to household income, indicating that social factors play very important roles in poverty alleviation in Bangladesh. Future poverty alleviation policy options need to give priority to investments in human, physical and natural capital assets.     

Migrant fishers of Pemba: Drivers,impacts and mediating factors

Most of the fishers of coastal East Africa particularly among the Bajuni, Kojani, Macua and Vezo ethnic communities have historically practiced migration. This study explores the strategies used by migrant fishers’ of Pemba in the Western Indian Ocean region. By adopting a modified sustainable livelihoods framework (SLF), the study uses in-depth interviews and questionnaires to explore the life histories of the fishers in migrant communities, their motivations to migrate, and their associated socioeconomic and ecological implications. Results point out to a complexity of factors contributing to migration including natural, to economic and social factors. Interaction of such factors is instrumental in shaping fisher migration as an activity into an important livelihood strategy. The study concludes that SLF provides holistic understanding of migration. However the incorporation of the ‘livelihood spaces’ extends this knowledge by integrating the spectrum of spatial aspects. This understanding is critical in the design of policies and interventions necessary to ensure resource sustainability and secure fishers livelihoods. This multi-method approach is critical in empirical study of fisher migration.     

Understanding influences in policy landscapes for sustainable coastal livelihoods

Ensuring sustainability of livelihoods for communities residing in coastal environments of the Global South has gained considerable attention across policy making, practice and research fields. Livelihood enhancement programs commonly strategize around developing people's resilience by diversification of income and subsistence activities, but are criticised for inadequate appreciation of local contexts. This in part results from the application of theoretical approaches in practice which are informed disproportionately by dominant science-based narratives and utilised by actors in higher level political arenas. This leads to the prioritization of objectives that do not necessarily reflect local livelihood conditions. There is an urgent need to address the multiple challenges that limit the possibility for sustainable livelihoods in spatially and temporally dynamic environments. This paper presents an analysis of the policy landscape in which intervention strategies for sustainable coastal livelihoods emerge. It examines how livelihood improvement approaches take shape in the context of conservation, rural development, and regional resource governance. Drawing from analyses of broader regional policies and an extensive literature review, a conceptual framework is presented. It details various influences that can flow up or down multi-scaled governance structures to affect policy and management - from agenda-setting narratives of policy makers to the dynamic and changeable nature of livelihoods. Case studies from the Arafura and Timor Seas region are introduced to illustrate some of these trends. The discussion highlights challenges encountered in the pursuit of sustainability for coastal and marine-based livelihoods, and suggests directions for more effective long term policy, management and strategic interventions.     

Limits and barriers to adaptation to climate variability and change in Bangladeshi coastal fishing communities

Limits and barriers to adaptation restrict people’s ability to address the negative impacts of climate change or manage risks in a way that maximises their wellbeing. There is a lack of evidence of this on small-scale fishing communities in developing countries. This study identifies and characterises limits and barriers to adaptation of fishing activities to cyclones and examines interactions between them in two fishing communities in Bangladesh, using household questionnaires, oral history interviews, vulnerability matrices and focus group discussions. The limits include physical characteristics of climate and sea like higher frequency and duration of cyclones, and hidden sandbars. Barriers include technologically poor boats, inaccurate weather forecast, poor radio signal, lack of access to credit, low incomes, underestimation of cyclone occurrence, coercion of fishermen by the boat owners and captains, lack of education, skills and livelihood alternatives, unfavourable credit schemes, lack of enforcement of fishing regulations and maritime laws, and lack of access to fish markets. These local and wider scale factors interact in complex ways and constrain completion of fishing trips, coping with cyclones at sea, safe return of boats from sea, timely responses to cyclones and livelihood diversification. The findings indicate a need for further detailed research into the determinants and implications of such limits and barriers, in order to move towards an improved characterisation of adaptation and to identify most suitable means to overcome the limits and barriers.     

Development policies,state interventions and struggles for livelihood rights in coastal communities in Kerala,India: A case study of the Cochin clam fishery

One of the major dilemmas of using rural commons for industrial uses in developing countries relates to the failure of the state to evolve consensus on allocating property rights to local communities and modern enterprises in a manner that sustains livelihoods and ecosystems. While traditional coastal communities enforce customary rights for fishing and mineral mining, the state sometimes reallocates traditional fishing territories to commercial mining to facilitate rapid industrialization. Communities oppose such transfers because of the negative impacts of commercial dredging on traditional fishing and ecosystems. Based on detailed field level surveys conducted in 2004, this paper describes how rural island communities along Cochin estuary expressed their opposition to the transfer of clam-mining rights to industries by democratic social mobilization. Counter moves were collectively organized by modern enterprises and trade unions which had the support of the state. However, major political parties retreated from conflict management, leaving the matter in a state of flux. This paper suggests that the state must recognize traditional livelihood rights of communities if it is to resolve conflicts and ensure the sustainable and equitable use of natural resources.     

Social indicators of vulnerability for fishing communities in the Northern Gulf of California,Mexico: Implications for climate change

Marine fisheries support the livelihoods of millions of people worldwide. These fisheries and the communities that depend on them are highly vulnerable to climate change and other interacting anthropogenic threats. The cumulative and interacting effects of these stressors could potentially produce declines in fish production, which would significantly impact artisanal fishers. Assessing relative vulnerability of fishing communities to anthropogenic stressors is an important first step to identifying mitigation or adaptation strategies. This study assessed the vulnerability of 12 coastal communities in the Northern Gulf of California to disruptions in fishing activities from anthropogenic stressors, including climate change. The Northern Gulf is a megadiverse area and a major source of fishery resources. Quantitative indicator indices based on secondary and primary data were developed to assess the three aspects of vulnerability: sensitivity, exposure, and adaptive capacity. The key components of vulnerability varied amongst communities. Vulnerability was higher in communities with higher fishing dependence and lower socioeconomic diversification. The approach presented here provides important insights into the type of policy actions that might be needed in different communities for adaptation and mitigation.     

Resilience to change in two coastal communities: Using the maximum dexterity fleet

Using whole-ecosystem dynamic simulation models fitted to local data, two coastal communities are described (temperate, northern British Columbia, Canada; tropical, Raja Ampat, Indonesia) where relatively poor fishers’ livelihoods are threatened by climate change and overfishing. A novel theoretical minimum bycatch scenario, the ‘maximum dexterity fleet’, is combined with a search algorithm specifying optimal fisheries to achieve economic and biodiversity goals. Potential gains made by approaching an optimal fleet configuration prove robust against increased risks from climate variability. Although fish, gear and way of life differ greatly, in both communities it is suggested that dexterity (adroitness in adapting fishing gear) could lead to improved benefits from fishing.     

The end of shark finning? Impacts of declining catches and fin demand on coastal community livelihoods

For several decades, fishing sharks for their fins has provided important livelihoods for eastern Indonesian coastal communities that fish the Halmahera, Arafura and Timor Seas. Fishery and interview data collected in 2012-13 from three case studies on the islands of Seram, Aru and Rote were used to examine changes in shark fishers’ livelihoods over the preceding 20 years. While recent declines in catches and shark fin prices have had a substantial impact on fishers’ livelihoods, the fishery's low visibility in some areas of its geographic range and its political complexity in general have meant that government and international development agencies have largely been unaware of this impact. Many respondents remembered the Asian Financial Crisis in 1997-98 and the turn of the millennium as a time when sharks were still abundant and shark fin prices high, but were concerned about the on-going fall of shark fin prices since March 2012. High-value species, particularly guitarfish, hammerhead and sandbar sharks were most affected, losing up to 40% of their pre-2012 value. These changes, combined with the loss of fishing grounds, few attractive options for alternative income and restrictive debt relationships with shark fin bosses, have led some fishers to resort to high-risk activities such as blast fishing, illegal transboundary fishing, and people smuggling. This paper examines the multi-layered causes and consequences of fishers’ decision-making in response to adverse changes in their fishery, and explores options and obstacles to pursuing livelihoods that carry lower environmental, financial and personal risks.     

Socio-economic vulnerability due to climate change: Deriving indicators for fishing communities in Mumbai

This paper assessed the socio-economic implications of climate change and vulnerability of fishing communities known as “Koli” living in Mumbai, India. The vulnerability indicators are derived from sustainable livelihood literature and use of multi-criteria analyses and are validated with expert opinions. A survey of two hundred fishermen from five fishing villages in Mumbai was conducted to collect data. The results demonstrate that vulnerability perpetuates due to physical and financial resource constraints among the fishing community. Fishermen from Madh and Worli villages are observed to be more vulnerable and less adaptive due to their inability to use efficient mechanized boats and advanced fishing implements, such as fish finders and GPS (Global Positioning System). The divergence in the vulnerability scores among fishing villages is attributed to the coping strategies, resource availability, knowledge and the benefit derived from the local government. Fishermen have been observing the negative impacts of climate change on their fishing livelihoods. Adaptation strategies to maximize fish catch are observed in such practices as targeting different species and fishing intensively for several days. However, these practices are leading to an imbalance in the common resource pool and biased resource sharing among different groups of fishermen.     

Working up an appetite for lionfish: A market-based approach to manage the invasion of Pterois volitans in Belize

Located on the Caribbean coast of Central America and flanked by the second longest barrier reef in the world, Belize is a nation reliant upon marine resources. Each year, the country’s predominantly small-scale fisheries generate an estimated US$22 million in revenue – 1.8%of GDP – and employ 3000 people. However, the nation’s fishing communities are facing an unprecedented challenge. Existing threats posed by declining fish stocks have been exacerbated by the introduction of the invasive alien red lionfish Pterois volitans in 2008. This Indo-Pacific predator has the potential to cause significant losses to the recruitment of native fish, in turn disrupting coral reef community dynamics in the Belize Barrier Reef Reserve System, a UNESCO World Heritage Site. Howefver, targeted lionfish fishing may offer a cost effective means to control the invasion, while also creating an alternative livelihood solution and improving food security among Belize's coastal fishing communities. This study summarises the recent history of the lionfish invasion in Belize, describes the multi-sector approach being used to address the invasion, and presents preliminary research summarising the characteristics of invasive alien lionfish in Belize. Data from Belize's nascent ‘lionfishery’ are also presented, demonstrating that demand for lionfish is outweighing supply – largely as a result of awareness-raising initiatives – and highlighting the strong potential for replication of this approach elsewhere in the Caribbean. The study concludes by discussing the barriers and potential solutions to this market-based approach to invasive species management.
