Marine protected areas (MPAs) are among the most widely accepted methods of marine management. MPAs are not, however, always placed such that they can maximize impact on conservation and livelihoods. Current MPA guidelines fall short in focusing primarily on biophysical criteria, overlooking interrelated socioeconomic factors. We identified 32 socioeconomic factors that influence whether MPA placement has an impact on biodiversity and/or livelihoods and weighted the quality of evidence using a novel “Evidence for Impact” Score. Results suggest that stakeholder engagement, poverty, population density, and strong leadership have most potential to positively impact biodiversity and/or livelihoods, but the direction of impact (i.e., positive or negative) can be context-dependent. We found a generally poor evidence base for impact evaluation of socioeconomic factors: though some factors were highly cited, few studies actually evaluate impact. Results indicate the need for a more interdisciplinary approach to MPA placement and more empirical studies that assess impact.  相似文献

Marine protected areas (MPAs) – or sections of the ocean set aside where human activities such as fishing are restricted – have been growing in popularity as a marine conservation tool. As a result, it is important to examine the socioeconomic consequences of MPAs and how they may affect nearby communities. This study explores social and equity issues surrounding the designation of the Marianas Trench Marine National Monument, an MPA that includes protections around the three most northern islands in the US territory of the Commonwealth of the Northern Marianas Islands (CNMI). We gathered oral history interviews with 40 individuals from CMNI and Guam who had connections to the waters in the newly-designated MPA and reviewed key documents in order to (1) document historical and current use of the waters in the MPA and (2) consider the implications that proposed fishing regulations in the MPA may have for the local communities. Our study documented 129 trips to visit the waters in the MPA in living memory. We found that due to distance, trips to the MPA waters were rare but culturally significant events that provided residents from CNMI and Guam with connections to their indigenous roots. Regulation of fishing in the new MPA has the potential to directly and indirectly restrict local access to these culturally important waters. This research highlights the importance of better collaboration with local partners and better consideration of social and equity concerns in the siting and regulation of MPAs.  相似文献

Inshore artisanal fishing in Malta is under intense spatial competition as the coastal zone is fragmented by multiple uses and designations including maritime transport, infrastructure, industrial fisheries, aquaculture, tourism and recreation. This research, adopting a grounded visualization methodology, explains how the artisanal fishing sector has undergone and been affected by ‘spatial squeezing’. Our results show that artisanal fishermen have been forced to give up fishing grounds or co-exist with other uses to the point where the ability to fish is becoming increasingly challenging. These difficulties might escalate with the advent of the marine protected areas (MPAs) which encompass nearly half of the inshore fishing zones. Since there does not seem to be effective MPA consultation mechanisms that elicit the real social, cultural and economic value of artisanal fishing grounds, fishermen feel threatened, alienated and disempowered. This study urges for a more holistic approach to spatial marine planning and accentuates the need of realizing the dependency of the artisanal sector on the inshore zones in the implementation of conservation measures, such that the prolonged existence of the coastal fishing communities is not jeopardized.  相似文献

《南极海洋生物资源养护公约》框架下的海洋保护区建设备受国际社会关注。2009年,南极海洋生物资源养护委员会建立了第一个海洋保护区,但2012年以来,罗斯海海洋保护区提案以及东南极海洋保护区代表体系提案却一直没有进展,其中涉及了南极条约体系解读与海洋保护区定义等法律争论、保护区建设与地缘政治控制以及排斥其他国家渔业活动等政治争论。研究表明,虽然委员会有权建立海洋保护区,以实现养护南极生物资源的目标,但两个提案一定程度上超越了委员会的职责范围;且这两个提案一定程度上都与提案国的南极领土主权以及渔业活动相关联,无法排除其他国家的政治关切;提案每年变化,也体现了政治妥协。因此,为真正实现按公约养护南极生物资源的目标,应切实解决相关的法律与政治关切,提高程序的透明度,扩大参与度,并认真实施对已建立的海洋保护区的研究与监测。  相似文献

This paper argues for a multidisciplinary framework to assess the relationship between environmental processes and social sciences that can be adapted to any geographic location. This includes both physical (earthquake hazard) and human (social vulnerability) dimensions in the context of disaster risk reduction. Disasters varies drastically depending on the local context. Indeed, the probability of a natural disaster having more devastating effects in one place than in another depends on the local vulnerability components of the affected society (cultural, social and economic). Therefore, there is an important correlation between the potential risk and the social resistance and resilience of a specific place, thus the disaster response varies according to the social fabric. In this context, the evaluation of social vulnerability is a crucial point in order to understand the ability of a society (studied at individual, household or community level) to anticipate, cope with, resist and recover from the impact of natural disaster events. Within this framework, the paper discusses how it is possible to integrate social vulnerability into the seismic risk analysis in Italy. Specifically, socioeconomic indicators were used to assess and mapping social vulnerability index. Afterwards, a Geographic Information System (GIS) approach was applied to identify the spatial variability of social vulnerability to seismic hazard. Through the use of a risk matrix, the classes of a social vulnerability index map were combined with those of a seismic hazard map proposed by INGV (National Institute of Geophysics and Volcanology). Finally, a qualitative social vulnerability exposure map to an earthquake hazard was produced, highlighting areas with high seismic and social vulnerability levels. Results suggest the importance of the integration of social vulnerability studies into seismic risk mitigation policies, emergency management and territorial planning to reduce the impact of disasters.  相似文献

Current, spatially explicit, and high-resolution assessments of population vulnerability to climate change and variability in developing countries can be difficult to create due to lack of data or financial and technical capacity constraints. We propose a comparative, multiple-approach framework to assess the spatial variation of population vulnerability to climatic changes using several high-resolution variables related to climate, topography, and socioeconomic conditions with an objective to detect the spatial variability of climate vulnerability in Nepal. Nepal is one of the most vulnerable countries to the effects of climate change due to frequent climatic hazards and poor socio-economic capacity. We used a climate vulnerability index (CVI) approach to derive climate vulnerability maps at the one-kilometer resolution and test an additive and a principal components-based composite method of data aggregation. In this work, we attempt to answer three questions. 1) How do different methods of assessment inform the spatial variation of the climate vulnerability in Nepal? 2) How do different variables interact to shape climate vulnerability in Nepal? 3) What proportions of the population in Nepal are vulnerable to climatic disasters and why? Our analysis uncovered significant spatial variations in population vulnerability to climate change across Nepal, with the highest vulnerability being experienced by the High Mountain region followed by the regions in the lower elevations. We find that although the lack of adaptive capacity is the biggest cause of population vulnerability to climate change in Nepal, a resilient community is shaped by both biophysical and socioeconomic characteristics. By performing an iterative sensitivity analysis of our thirteen variables both at the aggregate level (nationally) as well as at the more disaggregated (physiographic region) level, we contribute to identifying important, multi-scalar driving factors for vulnerability that can be employed as leverage points for lowering vulnerability at different scales. After performing analyses at multiple regions, we conclude that region-specific variable selection is needed for more detailed assessments and in order to prioritize adaptation strategies at scales that go beyond the hierarchy of administrative divisions.  相似文献

This study evaluates new multi-scale, multi-indicator methods for assessing the vulnerability of crop production to drought at a national and regional scale. It does this by identifying differences across and within ten regions of Ghana, a country that faces many climate and crop production challenges typical of sub-Saharan Africa. In particular, we illustrate how a quantitative national and regional study is a critical first step in assessing differences in the drought sensitivity of food production systems and show how such an assessment enables the formulation of more targeted district and community level research that can explore the drivers of vulnerability and change on a local-scale. Finally, we propose methodological steps that can improve drought sensitivity and vulnerability assessments in dynamic dryland farming systems where there are multiple drivers of change and thresholds of risk that vary in both space and time. Results show that the vulnerability of crop production to drought in Ghana has discernible geographical and socioeconomic patterns, with the Northern, Upper West and Upper East regions being most vulnerable. Partly, this is because these regions have the lowest adaptive capacity due to low socioeconomic development and have economies based on rain-fed agriculture. Within these regions we find considerable differences between districts that can be explained only partly by socioeconomic variables with further community and household-scale research required to explain the causes of differences in vulnerability status. Our results highlight that national and regional scale multi-indicator vulnerability assessments are a vital (and often ignored) first step in assessing vulnerability across a large area. These inputs can guide both local-level research and also demonstrate the need for region-specific policies to reduce vulnerability and to enhance drought preparedness within dryland farming communities.  相似文献

This article assesses the vulnerability to climatic and socioeconomic stresses in the Reef Islands, Solomon Islands, an atoll island group in the Southwest Pacific. Climate change and the associated sea-level rise are often seen as the most pressing challenges to atoll communities, yet this study aims at critically re-assessing this view by placing climate in the context of a range of other internal and external stressors affecting local livelihoods, including population growth, inadequate land use practices, and lack of economic potential, as well as external factors such as poorly developed infrastructure, economic marginalization and weak governance of Solomon Islands. Findings suggest that some of these non-climatic stresses are currently – and in the short term – more important determinants of local vulnerability than climate change and sea-level rise. Certainly, these stresses are likely to be exacerbated by different elements of climate change in the short, medium and long term, but generally speaking climate change does not appear to be a major driver of the current changes in the islands. On the basis of these observations, the possible adaptation options, relevant to different time scales, are discussed.  相似文献

传统时期太湖流域的渔民群体分为陆上定居的兼业渔民(仍属农民身份)和水上流动的专业渔民,其生产与生活方式因水环境和鱼资源的分布而存在区域差异。太湖周边低地湖荡区的兼业渔民从事捕鱼的环境支持度和资源便利程度较高,渔业在农村副业序列中占有重要地位。东部河网地区水鱼资源欠丰,捕鱼技术简单,农民捕鱼生产的季节性和流动性较大。太湖上流动捕鱼的专业渔民生产技术高,具有规模化和互助性,构成自然捕捞商品鱼生产的主力大军。流动于东部内河上的专业渔民以单家独户生产为主,产量低收入少,缺乏互助合作。各类渔民共同具有的流动性和人口来源的复杂性,使其成为社会安全管理的重灾区,也是促成20世纪60,70年代政府彻底实施渔民上岸定居的重要原因。  相似文献

高温热浪作为一种常见的气象灾害,对人们的生产、生活、健康产生很大的影响。为探索福建省沿海与内陆城市高温热浪脆弱差异性及其形成机制,本文构建了包含暴露性、敏感性、适应性3个维度的高温热浪脆弱性评估模型(Vulnerability Scoping Diagram, VSD)。利用1994-2013年逐日极端高温数据和经济社会统计数据,分别对处于沿海和内陆的福州和南平市辖区进行高温热浪脆弱性及其3个维度(暴露性、敏感性、适应性)的评估与比较,并试图解释分析福州市辖区与南平市辖区高温热浪脆弱性的差异及其原因。结果显示:由于地理环境与社会经济系统的显著差异,近20年来,沿海地区高温热浪的脆弱性低于内陆地区,但随着经济发展导致的敏感性增加,前者不断攀升的脆弱性可能会超越后者;内陆地区的人类活动对环境的干扰程度相对较弱,其敏感性不断降低而适应性有所上升,使得其高温热浪的脆弱性不断降低。降低高温热浪脆弱性的关键在于同时增强区域适应性与降低敏感性,这对制定适应性措施具有积极的现实意义。  相似文献

Urban poverty is invariably linked to sociospatial dimensions of livelihood strategies. Gendered social relations, for example, have been seen to impact the ability of females to access resources, to gain assets, and to engage in viable income‐generating activities. Focussing on the livelihood strategies of the urban poor as they intersect with neoliberal economic reforms in contemporary Ghana, this paper draws on a field‐based survey of porters in Accra, mostly migrants from rural agricultural northern Ghana, whose primary livelihoods derive from transporting goods for clients in congested market areas of the urban industrial south. The paper highlights the gendered aspects of porters' livelihood experiences such as differences in migration patterns, reliance on physical labour and living conditions, which relatively few analyses have examined, especially as these relate to wider socioeconomic processes. The study illustrates how this perspective is important to understand the intersection of livelihood strategies, gender and national economic reforms in promoting both rural and urban development.  相似文献

This article investigates the complexities of fisher livelihoods and their interactions with the tourism industry on the Kenyan coast, to better understand how the prospects for alternative livelihoods, such as tourism, reduce fishing pressure. Data were derived from a questionnaire of 123 households and 30 interviews. Results showed that fishers cover the whole socioeconomic spectrum and that the role of fishing in livelihoods is heterogeneous both between individuals and for individuals over time. The majority of fishers do not combine tourism and fishing simultaneously, but livelihoods are characterized by a process of moving in and out of various activities as opportunities present themselves. There was no evidence of systematic or permanent displacement of fishers as a result of tourism. Given that fishing is not only an occupation carried out by those with no alternatives, prospects for alternative livelihoods systematically reducing fishing effort, predicated on this assumption, are questioned.  相似文献
