    政府在解决社会生态陷阱方面发挥着至关重要的作用,在这种情况下,社会和生态系统之间的反馈导致资源退化和生计贫困之间的加剧。虽然人们普遍认为,解决这些陷阱需要采取综合措施,实证研究往往侧重于个体措施的影响。本文调查了当地政府为解决小规模渔业和水产养殖中的诱捕器而采取的所有措施,并研究了这些措施如何有助于解决诱捕器。根据谭江泻湖的经验数据,越南中部,它发现政府制定的措施符合“良好做法”,侧重于生态和社会挑战。然而,在实践中,它优先解决生态挑战而不是社会挑战。政府主要引导资源和努力打击资源退化。解决高度依赖渔业资源和缺乏替代生计的措施往往被搁置。这些做法未能解决造成社会生态陷阱的关键驱动因素和强化反馈。这篇论文强调了科学之间的差距,解决社会生态陷阱的政策和实践。弥合这些差距和改变政府对陷阱的反应需要与政府有效沟通科学知识;促进研究人员之间的合作,政策制定者,管理者和实践者;向政府提供财政支持,解决政府缺乏政治意愿的问题。
    Governments play crucial roles in addressing social-ecological traps - situations where feedbacks between social and ecological systems lead to reinforcement between resource degradation and livelihood impoverishment. While it is widely recognized that resolving these traps necesitates integrated measures, empirical studies often focus on the impact of individual measures. This paper investigates all measures employed by the local government to address traps in small-scale fisheries and aquaculture and examines how these measures contribute to solving the traps. Based on empirical data from the Tam Giang lagoon, Central Viet Nam, it finds that the goverment develops measures that align with \"good practices\" which focus on both ecological and social challenges. Yet, in practice, it prioritizes addressing ecological challenges over the social ones. The government primarily directs resources and efforts toward combating resource degradation. Measures that tackle the high dependency on fisheries resources and lack of alternative livelihoods are often sidelined. These practices fail to address the key drivers and reinforceing feedbacks that create the social-ecological trap. The paper highlights gaps between science, policy and practice in addressing social-ecological traps. Bridging these gaps and transforming government responses to the traps require effective communication of scientific knowledge to the government; facilitation of collaborations among researchers, policymakers, managers and practictioners; provision of financial support to the goverment and addressing the lack of political will of the government.

    生计倡议在海洋保护区(MPA)中很常见,旨在减轻贫困或提高收入机会。然而,结果可以在现实中混合,以及随着时间的变化。此外,谁受益是一个关键的考虑因素,由于结果可能会根据不等式而有所不同,包括性别。这里,在桑给巴尔的三个MPA地区调查了不同生计策略的货币结果,坦桑尼亚。使用定量方法,结果显示,生计在六年内发生了变化,生计策略在贫困发生率和收入方面有所不同。生计倡议,即海藻养殖和旅游业,与长期生计相比,没有提供显著更高的货币回报,比如渔业。海藻养殖显示收入稳定,但主要在女户主家庭中的贫困发生率很高。在学习期间,男人主要留在渔业中,当女性转向小企业和渔业时,主要退出海藻养殖。这强调了对适应性的需求,快速变化的沿海地区对性别问题有敏感认识的管理。
    Livelihood initiatives are common within marine protected areas (MPAs) aiming for poverty alleviation or higher income opportunities. However, results can be mixed in reality, as well as change over time. Furthermore, who benefits is a key consideration, as results can vary based on inequalities, including gender. Here, the monetary outcomes of different livelihood strategies were investigated across three MPA regions in Zanzibar, Tanzania. Using a quantitative approach, the results show that livelihoods have shifted in a six-year period, with livelihood strategies differing in poverty incidence and income. Livelihood initiatives, namely seaweed farming and tourism, did not provide significantly higher monetary returns compared to long-standing livelihoods, such as fisheries. Seaweed farming showed income stability but a high poverty incidence predominantly within women-headed households. During the study period, men primarily remained in fisheries, whilst women shifted to small-scale businesses and fisheries, largely exiting seaweed farming. This underscores a need for adaptive, gender sensitive management within fast changing coastal contexts.

    互联网从城市扩展到农村和沿海地区,改变了生活的方方面面,包括生活方式和工作实践。尽管一些研究表明,互联网的使用在渔业部门至关重要,需要更多有关互联网使用与小规模渔民主观幸福感之间联系的信息。本研究首次尝试探讨网络使用对主观幸福感的影响,特别是小规模渔民。这项研究使用了来自东爪哇220名受访者的横截面数据,印度尼西亚。两阶段预测替代(2SPS)方法用于解决估计中的内生性问题。结果显示,捕鱼工具,获得信贷,和区域对小规模渔民使用互联网的决心产生了积极和显著的影响。储蓄和非农就业对收养决定产生重大负面影响。主要发现表明,使用互联网可以显着提高小规模渔民的主观幸福感(以幸福感和生活满意度为代表)。这表明,需要改善沿海地区的互联网基础设施,以支持渔业部门的经济活动,并促进小规模渔民的福祉。
    The expansion of Internet access from urban to rural and coastal areas has changed all aspects of life, including lifestyles and work practices. Although several studies have shown that Internet use is essential in the fisheries sector, more information about the link between Internet usage and subjective well-being among small-scale fishermen is needed. This study is the first attempt to investigate the effect of Internet use on subjective well-being, particularly for small-scale fishers. This study used cross-sectional data from 220 respondents in East Java, Indonesia. Two-stage predictor substitution (2SPS) approaches were used to address the endogeneity issue in the estimation. The results revealed that fishing tools, access to credit, and region positively and significantly influenced small-scale fishers\' determination to use the Internet. Savings and off-farm employment significantly and negatively affect adoption decisions. The main findings suggest that Internet use significantly increases small-scale fishermen\'s subjective well-being (proxied by happiness and life satisfaction). This suggests that improving the Internet infrastructure in coastal areas is needed to support economic activities in the fisheries sector and boost the well-being of small-scale fishers.

    小型渔业(SSF)使用静态渔具,这些渔具被认为比拖曳渔具更有利地与海洋生态系统相互作用。尽管如此,trammel网,地中海SSF中使用最广泛的渔具之一,产生大量的丢弃物,可以占捕获生物量的25%或更多。废弃的生物可能包括濒危或受威胁的物种,如弹性枝,以及损坏渔具或导致解开延误的非商业无脊椎动物。我们评估了各种trammel-net齿轮改装,包括(i)使用附于脚绳的防护网,(ii)增加脚绳与网面板之间的索具绳线的长度,和(iii)减小外板的网眼尺寸。最后两项修改成功地降低了对大理石射线鱼雷marmorata的捕获,通常在研究区域丢弃。这两种修改都相对简单,他们的制造并不代表实施的额外成本,最重要的是,它们不会对目标物种的捕捞产生负面影响。目前的研究表明,事先评估不同等级的丢弃情况对于完成特定物种的装备改造至关重要,并强调了科学家之间合作的重要性,渔民和渔具制造商。
    Small-scale fisheries (SSF) use static gear which are thought to interact with marine ecosystems more benignly than towed gear. Despite this, trammel nets, one of the most extensively used type of fishing gear in the Mediterranean SSF, generate large amounts of discards, which can account for 25% or more of the captured biomass. Discarded organisms may include endangered or threatened species such as elasmobranchs, as well as non-commercial invertebrates that damage fishing gear or cause disentanglement delays. We evaluated various trammel-net gear modifications, including (i) the use of a guarding net attached to the footrope, (ii) increasing the length of the rigging twine between the footrope and the netting panel, and (iii) decreasing the mesh size of the outer panels. The last two modifications were successful in lowering captures of the marbled electric ray Torpedo marmorata, which is commonly discarded in the study area. Both sorts of modifications are relatively simple, their manufacturing does not represent an added cost to implement, and most importantly they do not negatively affect the catch of the target species. The current study shows that prior evaluation of the discard profile of distinct métiers is essential to accomplish species-specific gear modifications and underlines the importance of collaboration among scientists, fishers and gear manufacturers.

    渔民拥有详细的当地生态知识(LEK),这可能是跟踪研究较少的热带河流长期环境变化的宝贵资源。我们的目标是调查巴西亚马逊河三条清澈河流的这种变化,专注于水文学,水质和土地覆盖。此外,我们的目标是比较三条河流之间的这些变化(Trombetas,Tapajós和Tocantins)代表环境变化的潜在梯度。我们采访了129名渔民(塔帕霍斯67名,33在Tocantins和29在Trombetas),并通过MapBiomas项目制作的地图分别分析了土地覆盖和水文的时间序列,以及巴西国家水务局过去34年(1985年至2019年)的数据。这三个数据库的互补分析(映射,水文数据和渔民知识)揭示了所研究河流的环境变化。地图显示了土地覆盖的人类变化梯度,从改变较少的特隆贝塔斯河,Tapajós发生了适度的变化,而Tocantins河中的景观变化更为剧烈。来自Tocantins河的渔民报告说,与人类行为有关的水质出现了更多的负面变化,比如水坝,森林砍伐,和污染。此外,大多数渔民表示,近年来水文变化使得托坎廷斯河更加干燥,这会对鱼类种群造成负面影响。在塔帕霍斯河中,渔民提到了更多不同的水文模式和与采矿活动相关的对水质的负面影响,而在Trombetas,渔民认为洪水增加。采访的渔民提到的变化与水文数据中观察到的趋势相匹配,表明受影响更大的托坎廷斯河干旱增加的趋势。渔民的知识提供了独家的地面数据,以跟踪当地水文和水质的长期变化,以及告知这些变化对鱼类和渔业的影响。
    Fishers possess detailed local ecological knowledge (LEK) which can be a valuable resource for tracking long-term environmental changes in less studied tropical rivers. Our goal was to investigate such changes in three clear water rivers in the Brazilian Amazon, focusing on hydrology, water quality and land cover. Additionally, we aimed to compare these changes among three rivers (Trombetas, Tapajós and Tocantins) representing a potential gradient of environmental changes. We interviewed 129 fishers (67 in Tapajós, 33 in Tocantins and 29 in Trombetas), and analyzed temporal series on land cover and hydrology respectively through maps produced by the project MapBiomas, and data from the Brazilian National Water Agency across the last 34 years (from 1985 to 2019). The complementary analyses of these three databases (mapping, hydrological data and fishers\' knowledge) revealed environmental changes in the studied rivers. The maps showed a gradient of anthropic changes on land cover, from the less altered Trombetas river, the moderately altered Tapajós and the more intensely changed landscape in the Tocantins River. Fishers from the Tocantins River reported a greater variety of negative changes in water quality related to anthropic actions, such as dams, deforestation, and pollution. Additionally, most fishers indicated hydrological changes making the Tocantins River drier in more recent years, which would cause negative effects on fish populations. In the Tapajós River, fishers mentioned more varied hydrological patterns and negative effects on water quality linked to mining activities, whereas in Trombetas fishers perceived increased floods. The changes mentioned by the interviewed fishers matched observed trends from hydrological data indicating a trend of increasing droughts in the more impacted Tocantins River. Fishers\' knowledge provided exclusive \'on the ground\' data to track long-term changes on local hydrology and water quality, as well as inform the effects of these changes on fish and fisheries.

    尽管在Ubatuba的Lázaro和SacodaRibeira的Caiçara小规模捕鱼社区成员的生活中有很多,巴西东南部会暗示困难,人们对生活的满意度令人惊讶。在本文中,我们使用通过人种学应用的社会福祉镜头,混合方法的方法来反思这种整体感觉,即植根于小规模捕鱼的生活非常值得生活,尽管它们面临许多挑战。我们将经典的海洋人类学主题视为意义和生活满意度的核心。身份提供了人们如何与现实互动的核心方面,并锚定了作为工作和社会关系参考点的价值观。参考社会福祉视角揭示的关系细微差别,然而,我们表明,凯萨拉和小规模捕鱼的身份不是单一的,但反映了性别和其他社会地位,以及个人和家庭经历。这些经验包括努力应对经济的复杂影响,社会,政治,和环境变化。最后,我们认为,寻求优先考虑人类福祉的渔业政策将通过采用社会福祉观点而受益。因此,渔业政策可以考虑到身份,值,和社会生活的关系元素赋予了小规模渔民的意义和归属感,同时也认识到由于社会和经济差异而引起的人类经验的交叉变化,而且往往是相互矛盾的。小规模渔民的这种社会结构塑造了他们的意图和行动,因此是其支持者需要考虑的渔业管理实践的必要复杂性。
    Although much in the lives of members of the Caiçara small-scale fishing communities of Lázaro and Saco da Ribeira in Ubatuba, southeastern Brazil would suggest hardship, that population expresses a surprising degree of satisfaction with life. In this paper, we use a social wellbeing lens as applied through an ethnographic, mixed methods approach to reflect on this overall sense that lives rooted in small-scale fishing are well worth living despite their many challenges. We see the classic maritime anthropology theme of identity at the heart of meaning and life satisfaction. Identity provides core aspects of how people engage with their realities and anchors values that are reference points in work and social relations. With reference to the relational nuances revealed by the social wellbeing perspective, however, we show that Caiçara and small-scale fishing identities are not monolithic, but reflect gender and other social positions, and personal and familial experiences. These experiences include grappling with the complex effects of economic, social, political, and environmental changes. We conclude by arguing that fisheries policy that seeks to prioritize human wellbeing would benefit by adopting a social wellbeing perspective. Fisheries policy could thereby take into account identity, values, and relational elements of social life that give meaning and a sense of belonging to small-scale fishers, while also recognizing the cross-cutting and often contradictory variations in human experience that arise from social and economic differences. This social fabric of small-scale fishers\' lives shapes their intentions and actions and is thus a necessary complication to the practice of fisheries management that its proponents need to consider.

    管理被遗弃,丢失和以其他方式丢弃的渔具(ALDFG)是一项关键挑战,可以通过建立强有力的渔具标记条款来帮助。本研究分析了VGMFG在东加勒比海州的实施情况。它对这一问题进行了社会法律审查,并分析了遵守和执行方面的差距。通过采访2个司法管辖区的56名渔民以及6名国家和区域渔业管理专家,收集了经验数据。安提瓜和巴布达的《渔业条例》为VGMFG的实施提供了最强有力的支持,而多米尼加和格林纳达都没有对装备标记的监管支持。该区域的渔民和渔业管理人员都确认了在建立渔具标识计划方面的遵守和执行差距,虽然区域渔业专家强调了有限的人类,各部门的财政和基础设施能力,以有效实施这些计划以及其他ALDFG管理措施。
    Managing abandoned, lost and otherwise discarded fishing gear (ALDFG) is a critical challenge that can be aided by the establishment of strong provisions for the marking of gear. This study presents an analysis of implementation of the VGMFG in Eastern Caribbean states. It provides a socio-legal review of this issues and an analysis of compliance and implementation gaps. Empirical data was gathered through interviews with 56 fishers in 2 jurisdictions as well as 6 national and regional fisheries management experts. Antigua and Barbuda\'s Fisheries Regulations provided the strongest support to implementation of the VGMFG, while neither Dominica nor Grenada had weak regulatory support for gear marking. Both fishers and fisheries managers in the region confirmed compliance and implementation gaps in the establishment of gear marking schemes, while regional fisheries experts highlighted the limited human, financial and infrastructural capacity of departments to effectively implement such schemes along with other ALDFG management measures.

    海洋垃圾是一个日益严重的环境问题,对渔业来源的废物仍然知之甚少。在秘鲁,鉴于缺乏接收渔民产生的各种碎片的设施,小规模渔业船队的废物管理面临着持续的挑战,其中包括电池等危险废物。在这项研究中,陆上观察员每天在Salaverry港口降落时监测船上固体废物的产生,秘鲁,2017年3月至9月。经分析的小型刺网和延绳钓捕鱼船队每年产生约11,260公斤固体废物。特别值得关注的是一次性塑料(3427公斤)和电池(861公斤)的生产,因为它们对环境的潜在持久影响以及与适当处置有关的挑战。已经为Salaverry制定了固体废物管理计划;因此,随后在2021-2022年对渔民对该计划实施情况的行为和看法进行了评估.大多数渔民(96%)报告说将废物丢弃在陆地上,除了在海上处置的有机废物。尽管Salaverry的渔民越来越意识到海上废物处理的问题,并有兴趣更好地隔离和管理其废物,港口仍然需要改进废物管理和回收协议和程序,以实现这一目标。
    Marine litter is a growing environmental problem for which fisheries-sourced waste remains poorly understood. In Peru, there is an ongoing challenge of waste management from the small-scale fisheries fleet given the lack of facilities to receive the variety of debris produced by fishers, which includes hazardous wastes such as batteries. In this study, onboard solid waste production was monitored daily by land-based observers upon landing at the port of Salaverry, Peru, from March to September 2017. The analysed small-scale gillnet and longline fishing fleets produced annually an estimated 11,260 kg of solid waste. Of particular concern is the production of single use plastics (3427 kg) and batteries (861 kg) due to their potential long-lasting impacts on the environment and challenges related to their proper disposal. A management plan for solid waste has been developed for Salaverry; therefore, a subsequent assessment was conducted in 2021-2022 of the behaviours and perceptions of fishers regarding the implementation of this plan. Most fishers (96%) reported disposing of their waste on land, except organic waste which is disposed of at sea. While fishers in Salaverry have become more conscious of the issues surrounding at-sea waste disposal and have an interest in better segregating and managing their waste, there remains a need for improved waste management and recycling protocols and procedures at the port to make this possible.

    自从国家政府为应对COVID-19大流行而对旅行和社会距离施加限制以来,印度尼西亚小规模渔业的渔获量和渔获量大幅下降。使用数字数据收集系统(OurFish),记录了鱼类商人从小规模渔民那里购买的商品,收集了苏拉威西岛东南部82个沿海社区的数据。我们发现,在大流行爆发后,活跃渔民和贸易商的数量下降了90%以上,每个渔民每次捕鱼的平均渔获量增加。尽管大流行开始后,每公斤鱼的平均价格有所下降,能够维持捕鱼的渔民平均渔获量较高,因此维持了每日渔获量。与通常出售给当地市场的低价值鱼种相比,通常进入出口供应链的高价值鱼种受到的负面影响更大。我们采访了苏拉威西省东南部82个社区中的20个社区的185个小规模渔民和鱼类贸易商,记录对当地渔业和鱼类贸易的影响程度,产生这种影响的原因并提出应对策略。超过50%的渔民和鱼类贸易商都认为,贸易商对鱼类的需求不足以及鱼类价格的下降正在破坏他们的生活。大约75%的男性和女性渔民都通过继续捕鱼来应对,强调采访时几乎没有替代生计。我们的研究结果为小规模捕鱼社区对COVID-19大流行影响的脆弱性提供了关键见解。
    The volume and value of fish catches by Indonesia\'s small-scale fisheries have declined significantly since national government restrictions on travel and social distancing were imposed in response to the COVID-19 pandemic. Using a digital data collection system (OurFish), that records purchases by fish traders from small-scale fishers, data was collected across 82 coastal communities in Southeast Sulawesi. We found that the number of active fishers and traders declined by more than 90% after the onset of the pandemic and the average weight of catch per fishing trip increased across fishers. Although the average price per kilogram of fish declined after the pandemic began, fishers that were able to maintain fishing had on average higher catches and therefore daily catch value was maintained. High value fisheries that usually enter export supply chains were more negatively impacted compared with lower value species that are commonly sold to local markets. We interviewed 185 small scale fishers and fish traders across 20 of the 82 communities in Southeast Sulawesi province, recording the perceived level of impact on local fisheries and the fish trade, causes of this impact and proposed coping strategies. Over 50% of both fishers and fish traders believed low demand for fish from traders and a decline in the price received for fish were disrupting their lives. Approximately 75% of both male and female fishers are coping by continuing to fish, highlighting that there were few alternative livelihoods available at the time of the interviews. Our results provide key insights into the vulnerability of small-scale fishing communities to impacts of the COVID-19 pandemic.

    气候变化,全球化,工业和城市活动的增加威胁到小规模渔业的可持续性和生存能力。受影响的人如何集体动员他们的行动,分享知识,建立他们的本地适应能力将决定他们如何最好地应对这些变化。本文考察了小规模捕捞行为者所经历的变化,社会和治理的复杂性,以及林贝渔业系统的可持续性挑战,喀麦隆。借鉴鱼类作为食物的框架,我们讨论了鉴于全球威胁的融合,无效的渔业管理如何导致鱼类收获机活动的变化,造成鱼类供应短缺和鱼类价值链中断。本文通过与鱼类收割机和鱼贩的焦点小组讨论,提出了三个关键发现。首先,我们表明,捕鱼活动的增加和渔业管理不力导致的渔业变化扰乱了鱼类的捕捞和供应,影响小规模捕鱼行为者及其社区的社会和经济福祉。第二,由于鱼类供应短缺,渔业价值链存在复杂性,在其活动不受任何特定规则或政策管制的渔业行为者之间造成冲突。第三,尽管林贝小规模渔业很重要,捕鱼行为者放弃了管理,他们没有适当的能力来设计和执行有效的渔业管理程序和防止非法捕鱼活动。这种未被充分研究的渔业的经验发现为鱼类作为食物框架的文献做出了学术贡献,并表明需要支持小规模行为者的捕鱼活动和林贝渔业系统的可持续性。

    Climate change, globalization, and increasing industrial and urban activities threaten the sustainability and viability of small-scale fisheries. How those affected can collectively mobilize their actions, share knowledge, and build their local adaptive capacity will shape how best they respond to these changes. This paper examines the changes experienced by small-scale fishing actors, social and governance complexities, and the sustainability challenges within the fisheries system in Limbe, Cameroon. Drawing on the fish-as-food framework, we discuss how ineffective fishery management in light of a confluence of global threats has resulted in changes to fish harvesters\' activities, causing shortages in fish supply and disruptions in the fish value chain. The paper uses focus group discussions with fish harvesters and fishmongers to present three key findings. First, we show that changes in the fisheries from increased fishing activities and ineffective fishery management have disrupted fish harvesting and supply, impacting the social and economic well-being of small-scale fishing actors and their communities. Second, there are complexities in the fisheries value chain due to shortages in fish supply, creating conflicts between fisheries actors whose activities are not regulated by any specific set of rules or policies. Third, despite the importance of small-scale fisheries in Limbe, management has been abandoned by fishing actors who are not well-equipped with the appropriate capacity to design and enforce effective fishery management procedures and protections against illegal fishing activities. Empirical findings from this understudied fishery make scholarly contributions to the literature on the fish-as-food framework and demonstrate the need to support small-scale actors\' fishing activities and the sustainability of the fisheries system in Limbe.
