Very little research has focused on climate impacts on aquaculture and the potential of climate information services (CIS) for aquaculture to support sustainable development goals 2030 (SDGs).1 This study represents an effort to bridge this gap by conducting a first ex-ante economic evaluation of CIS for aquaculture in Bangladesh by semi-automating the extraction of data on climate-induced fish losses during 2011 to 2021 from popular online newspaper articles and corroborating them with available government and satellite datasets. During this period, Bangladesh faced an estimated loss of around 140 million USD for hatcheries, open water fish and shrimp. When validated with a year of country-wide official data on climate-induced economic losses to aquaculture, the damage reported from these media sources is approximately 10 percent of actual losses. Given this rule of thumb, the potential economic value of aquacultural CIS could be up to USD14 million a year, if 10 percent of the damage can be offset by appropriate services through a range of multi-sector efforts to establish and extend these services to farmers at scale.

很少有研究关注气候对水产养殖的影响以及水产养殖气候信息服务(CIS)支持2030 年可持续发展目标(SDGs)1 的潜力。本研究通过半自动化从流行的在线报纸文章中提取2011年至2021年期间气候引起的水产品损失数据,并与现有的政府和卫星数据集相互印证,对CIS在孟加拉国的水产养殖进行了首次事前经济评估,从而弥补了这一差距。在此期间,孟加拉国的孵化场、露天水域鱼类和虾类估计损失约 1.4 亿美元。如果与全国范围内一年的气候导致水产养殖经济损失的官方数据进行验证,这些媒体报道的损失约为实际损失的10%。根据这一经验法则,如果通过一系列多部门努力,建立并向农民大规模推广适当的服务,以抵消10%的损失,那么水产养殖CIS的潜在经济价值每年可达1400万美元。

Recent advancements in spatial risk assessment methodologies, particularly those incorporating GIS and economic evaluations, have significantly enhanced our ability to assess and manage risks associated with natural disasters. Entrepreneurs, investors, and public administrations need information about climate change risks for effective planning and decision making. To move from generic global or national projections about climate change scenarios, towards more actionable information on climate risks for socioeconomic agents, the three dimensions of risk (Hazard, Exposure and Vulnerability) must be quantified and mapped with the involvement of stakeholders. In this study, spatial indicators, tailored to the social and ecological systems of interest and co-designed with the key stakeholders are aggregated into sectoral risk indexes quantified in economic terms. Climate risk indexes were calculated and mapped for the four key economic sectors of the study area of the Belluno Province (Italian Alps): summer tourism, winter sports and events, eyewear industry, and electricity supply. Stakeholders were involved during the assessment to share knowledge, data and needs and to provide expert judgments on intermediate and final results. Outputs include a series of maps and statistical summaries, highlighting future trends of climate related risks, their spatial variability within the area and the estimated levels of uncertainty. Estimates on expected changes of future damages with constant Exposure and Vulnerability, provided socioeconomic agents with simple and clear messages about how their activities could suffer or benefit from climate change in the future.
空间风险评估方法的最新进展,特别是结合地理信息系统和经济评估的方法,大大提高了我们评估和管理自然灾害相关风险的能力。企业家、投资者和公共管理部门需要有关气候变化风险的信息,以便进行有效的规划和决策。为了从一般的全球或国家气候变化情景预测转向为社会经济主体提供更具可操作性的气候风险信息,必须在利益相关者的参与下对风险的三个维度(危害、暴露和脆弱性)进行量化和绘图。在本研究中,根据相关社会和生态系统定制并与主要利益相关方共同设计的空间指标被汇总为以经济术语量化的部门风险指数。气候风险指数是针对贝卢诺省(意大利阿尔卑斯山)研究区域的四个主要经济部门计算和绘制的:夏季旅游业、冬季运动与活动、眼镜业和电力供应。在评估过程中,利益相关者参与其中,分享知识、数据和需求,并就中期和最终结果提供专家意见。成果包括一系列地图和统计摘要,突出了与气候相关风险的未来趋势、其在该地区内的空间可变性以及不确定性的估计水平。在 "暴露 "和 "脆弱性 "不变的情况下,对未来损害的预期变化进行估算,为社会经济行为主体提供简单明了的信息,说明他们的活动在未来可能如何受到气候变化的影响或从中受益。

Early warning systems in disasters are crucial for life preservation and loss mitigation, endorsed globally by various UN agencies, governments, and disaster researchers. However, the social aspects pose significant challenges to the success of early warning. Using survey data from Sanya, a coastal city in China, our study explores the relationship between early warning services and community engagement. The primary warning channels are social media (SMS and WeChat), the Internet, and TV. These mediums, along with traditional and mass media, foster higher community engagement, like volunteer service and disaster risk reduction efforts. Satisfaction with warning service mediates these connections. Interestingly, families with chronic disease members are more likely to engage in community activities and utilize the Internet and social media for warnings. Notably, different patterns emerge when comparing families with and without chronic disease members, especially regarding Internet and social media usage. This study enhances our understanding of public adaptation to disaster warnings and provides insight for early warning services in the face of increasing climate change impacts and meteorological disasters.

灾害预警系统对于保护生命和减少损失至关重要,在全球范围内得到了联合国各机构、各国政府和灾害研究人员的认可。然而,社会方面的问题给预警的成功带来了巨大挑战。我们的研究利用中国沿海城市三亚的调查数据,探讨了预警服务与社区参与之间的关系。主要的预警渠道是社交媒体(短信和微信)、互联网和电视。这些媒体以及传统媒体和大众媒体促进了更高的社区参与度,如志愿者服务和减灾工作。对预警服务的满意度是这些联系的中介。有趣的是,有慢性病成员的家庭更有可能参与社区活动,并利用互联网和社交媒体发布预警。值得注意的是,在比较有慢性病成员和没有慢性病成员的家庭时,出现了不同的模式,尤其是在互联网和社交媒体的使用方面。这项研究加深了我们对公众适应灾害预警的理解,并为面对日益严重的气候变化影响和气象灾害的预警服务提供了启示。

Climate change disproportionately impacts marginalized communities, but we also need to understand how addressing these impacts might exacerbate existing inequalities. Exploring how generic structural socioeconomic and political inequalities relate to responses to specific climate-driven hazards can help inform efforts to address climate-driven risks without reinforcing inequalities. This study sheds light on the relationship between generic capitals that local governance systems might draw on to reduce risks and a specific outcome that reduces the impact of climate-driven risks. We explore patterns in the amount of aid counties in the five Gulf States (Alabama, Florida, Louisiana, Mississippi, and Texas) received from the US Federal Emergency Management Agency’s Public Assistance Program from 2000 to 2020. Using linear regressions, we explore how the amount of aid these counties received relates to the presence of five dimensions of potential generic capitals (social, economic, political, human, and environmental) at the county-level. We found evidence that patterns in the distribution of aid were consistent with simultaneously both reducing and amplifying existing inequalities – e.g., counties with higher levels of individual poverty and more rural residents received more aid while counties with higher percentages of Black and Hispanic residents received less. At the same time, we found evidence that aid received might be particularly low for populations vulnerable due to both racial/ethnic inequities and lack of access to services located in more urbanized areas. These results highlight the need for assessments exploring the multidimensional nature of equity to prevent efforts to address climate-related risks further marginalizing those left behind.
气候变化对边缘化社区的影响尤为严重,但我们也需要了解应对这些影响可能会如何加剧现有的不平等。探索一般的结构性社会经济和政治不平等与应对特定气候灾害之间的关系,有助于为应对气候风险提供信息,同时避免加剧不平等。本研究揭示了地方治理系统可用于降低风险的一般资本与降低气候驱动风险影响的特定结果之间的关系。我们探讨了海湾五州(阿拉巴马州、佛罗里达州、路易斯安那州、密西西比州和得克萨斯州)各县在 2000 年至 2020 年期间从美国联邦紧急事务管理局公共援助计划获得的援助金额的模式。通过线性回归,我们探讨了这些县获得的援助金额与县级潜在通用资本的五个方面(社会、经济、政治、人力和环境)之间的关系。我们发现有证据表明,援助的分配模式与同时减少和扩大现有的不平等现象是一致的,例如,个人贫困程度较高、农村居民较多的县获得的援助较多,而黑人和西班牙裔居民比例较高的县获得的援助较少。同时,我们还发现有证据表明,由于种族/族裔不平等以及缺乏城市化地区的服务,弱势人群获得的援助可能特别少。这些结果突出表明,有必要对公平的多维性进行评估,以防止应对气候相关风险的努力进一步将那些落在后面的人边缘化。

The field of climate justice has been growing in relevance since its conception in 1997. This paper presents a comprehensive bibliometric and topic modelling analyses to examine the evolution and trajectory of the climate justice literature. We analyse 1,683 publications covering the period from 1997 to 2021, highlighting foundational works, influential authors, leading nations and institutions, and prevailing research topics within this field. We employ Latent Dirichlet Allocation to uncover latent research trends in the literature providing a crucial baseline for future scholarly endeavours and policy development in the realm of climate justice.

Our results show that the field of climate justice has grown exponentially from less than 5 papers annually between 1997 and 2005, to around 200 papers annually in recent years. This growth has seen a diversification of research themes with an increase in papers around the topics of health, vulnerability and adaptation, and policy and activism. There has been a consistent backdrop of publications around the topics of sustainable development and policy, and international relations and carbon emissions. Other prominent topics in the literature include education and food security, and human rights and Indigenous people. The field has moved from theoretical research to examining actual examples of climate injustices, with an increased diversification of topics.

Future research could usefully focus on exploring future generations and more-than-human entities; the integration of climate justice and climate activism with broader struggles for justice; re-thinking climate adaptation “success” and “effectiveness” through the lens of climate justice, and the ramifications of the Global Goal on Adaptation on climate justice led-approaches that are inclusive, build on human rights approaches, and extend the scale of adaptation analysis beyond the local. It is imperative to prioritise addressing the climate justice needs of those most affected by climate change, transcending national borders, generational gaps, cultural differences, and even the well-being of various species. Such a holistic approach will help inform and refine global climate policy and action.

气候正义领域自 1997 年提出以来,其相关性不断增强。本文通过全面的文献计量学和主题建模分析,研究了气候正义文献的演变和发展轨迹。我们分析了 1997 年至 2021 年期间的 1683 篇出版物,重点介绍了该领域的奠基性著作、有影响力的作者、领先的国家和机构以及流行的研究课题。我们采用潜狄利克特分配法(Latent Dirichlet Allocation)揭示了文献中的潜在研究趋势,为气候正义领域未来的学术研究和政策制定提供了重要的基线。我们的研究结果表明,气候正义领域的论文数量呈指数增长,从 1997 年至 2005 年的每年不到 5 篇,增长到近年来的每年约 200 篇。在这一增长过程中,研究主题呈现多样化趋势,围绕健康、脆弱性与适应、政策与行动主义等主题的论文有所增加。围绕可持续发展与政策、国际关系与碳排放等主题发表的论文也在持续增加。文献中其他突出的主题包括教育和粮食安全,以及人权和土著人民。未来的研究可以重点探讨后代和超人类实体;将气候正义和气候行动主义与更广泛的正义斗争相结合;通过气候正义的视角重新思考气候适应的 "成功 "和 "有效性",以及全球适应目标对气候正义主导的方法的影响,这些方法具有包容性,建立在人权方法之上,并将适应分析的范围扩展到地方之外。当务之急是优先解决受气候变化影响最严重者的气候正义需求,超越国界、代沟、文化差异,甚至各种物种的福祉。这种综合方法将有助于为全球气候政策和行动提供信息并加以完善。

Capturing cascading consequences is required to reflect risk from climate change and natural hazards 要反映气候变化和自然灾害的风险,就必须捕捉级联后果

Climate change and natural hazards present a major risk to individuals and communities; however, the current quantitative risk assessment methodologies struggle to capture the wider consequences that arise from society’s complex interconnections. These complex interconnections exist due to the number of mutually dependent systems and mean that impacts on one system can be felt in another. These cascading impacts present a major challenge to climate risk assessments. Climate risk assessments often consider a range of “wellbeing” or “value” domains; for example, in New Zealand the five wellbeing domains are Natural Environment, Human, Economic, Built Environment, and Governance. Existing assessments have sought to characterize the risk to each domain, but do not quantitatively or rigorously consider the interplay between the domains. For example, how does the risk to the human domain change as a result of the impacts to the built environment? This interplay and the ensuing cascading impacts could substantially modify the assessed risk. The change could potentially alter the prioritization and subsequent adaptation plans. In this paper, we show that considering cascading impacts not only increases the magnitude of risk but can shift the prioritization. This highlights the importance of capturing cascading impacts for effective adaptation to climate change.

气候变化和自然灾害给个人和社区带来了重大风险;然而,目前的定量风险评估方法难以捕捉到社会复杂的相互联系所产生的更广泛的后果。这些复杂的相互联系存在于许多相互依存的系统中,这意味着一个系统受到的影响会影响到另一个系统。这些连锁影响给气候风险评估带来了重大挑战。气候风险评估通常考虑一系列 "福祉 "或 "价值 "领域;例如,在新西兰,五个福祉领域是自然环境、人类、经济、建筑环境和治理。现有评估试图描述每个领域的风险特征,但没有定量或严格考虑领域之间的相互作用。例如,人类领域的风险如何随着对建筑环境的影响而变化?这种相互作用以及随之而来的连锁影响可能会大大改变评估的风险。这种变化可能会改变优先顺序和随后的适应计划。在本文中,我们表明考虑连带影响不仅会增加风险程度,还可能改变优先顺序。这凸显了把握级联影响对于有效适应气候变化的重要性。

This highlights the importance of capturing cascading impacts for effective adaptation to climate change.</p></div>","PeriodicalId":54226,"journal":{"name":"Climate Risk Management","volume":"44 ","pages":"Article 100613"},"PeriodicalIF":4.4,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2212096324000305/pdfft?md5=f336f60e1bdad34f7fd7c5ec12655244&pid=1-s2.0-S2212096324000305-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140775526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Climate change-related challenges faced by forest managers are ecological, economic, and social in nature. While several past assessments have looked at the climate-related perceptions and needs of foresters working in rural contexts, urban foresters are not often included in these assessments. Examining foresters’ risk perceptions, adaptation interests and intentions, and need for information/support in rural and urban contexts side-by-side reveals unique opportunities for learning across the rural-to-urban gradient. Through two surveys targeting both rural and urban foresters, we have identified key learning opportunities that support climate-adaptive forest management.

Our analysis shows that many foresters are seeking to maintain current forest conditions or restore forest conditions following a disruption or change, though some see value in transitioning forests to be more resistant and resilient to future climates. We also show a difference in confidence between urban and rural foresters when it comes to addressing climate change through specific adaptation strategies. Based on our findings, we propose facilitated learning opportunities across the rural-to-urban gradient. This would allow urban foresters to learn from rural foresters on topics such as establishment and maintenance of long-term, large, ecologically complex forested areas within cities. Rural foresters could gain insights from their urban counterparts on planting strategies and other approaches that are common in urban settings but novel in rural settings, including stock sourcing and species selection.

To better enable foresters to implement climate adaptation strategies, we suggest: (1) facilitating learning across the rural-to-urban gradient, (2) public engagement trainings and opportunities targeting foresters, (3) workforce development programing, and (4) programs that limit the financial risk that foresters, landowners, and municipalities face when applying forest adaptation strategies to rural or urban lands.

森林管理人员面临的气候变化相关挑战具有生态、经济和社会性质。虽然过去的一些评估研究了在农村地区工作的林务人员对气候相关问题的看法和需求,但城市林务人员往往不在这些评估范围之内。对农村和城市林务人员的风险认知、适应兴趣和意向以及对信息/支持的需求进行并排研究,揭示了从农村到城市梯度之间独特的学习机会。我们的分析表明,许多林务人员正在寻求维持当前的森林状况,或在中断或变化后恢复森林状况,尽管有些人认为森林转型的价值在于提高对未来气候的抵抗力和复原力。我们还发现,在通过具体的适应战略应对气候变化方面,城市和农村林务人员的信心存在差异。根据我们的研究结果,我们建议在农村到城市的梯度上提供便利的学习机会。这将使城市林业工作者能够向农村林业工作者学习如何在城市内建立和维护长期、大型、生态复杂的林区。为了更好地帮助林务人员实施气候适应战略,我们建议:(1)促进从农村到城市的梯度学习;(2)针对林务人员的公众参与培训和机会;(3)劳动力发展计划;(4)限制林务人员、土地所有者和市政当局在农村或城市土地上应用森林适应战略时所面临的财务风险的计划。

Adapting reservoir operation to climate change in regions with long-term hydrologic persistence 在具有长期水文持续性的地区使水库运行适应气候变化

Large-scale climate variability patterns such as El Niño-Southern Oscillation (ENSO) influence the hydrology and hence affect the management of water resources in numerous regions around the globe. The presence of multiyear drought and wet periods is already challenging as these long, extreme, events tend to stress water resources systems much more than multiple, isolated, ones. This manuscript presents a variant of a hydrologically-driven approach to assess the performance of large-scale water resources systems in regions where the long-term persistence that characterizes the flow regime is likely to be affected by climate change. This approach comprises several steps including the construction of a large ensemble of hydrological projections which are bias-corrected in the frequency domain to account for the long-term persistence; the clustering of these projections based on hydrologic attributes to identify likely alterations of the flow regime; and the use of an optimization model to derive allocation policies tailored to identified alterations of the flow regime. The proposed approach is tested on the Senegal River basin which has experienced multiyear dry, normal, and wet periods in the past. The analysis of allocation policies highlights the relevance of climate-tailored policies in adapting to climate change, with climate tailored policies yielding moderate gains under the most extreme alterations, while they remain meaningful under more moderate ones.

厄尔尼诺-南方涛动(ENSO)等大尺度气候变异模式会影响水文,进而影响全球许多地区的水资源管理。多年干旱和湿润期的存在已经是一个挑战,因为这些长期的极端事件往往比多个孤立的事件对水资源系统造成更大的压力。本手稿介绍了一种水文驱动方法的变体,用于评估大规模水资源系统在水流状态的长期持续性可能受到气候变化影响的地区的表现。该方法由几个步骤组成,包括构建一个大型水文预测集合,在频域中对其进行偏差校正,以考虑长期持续性;根据水文属性对这些预测进行聚类,以确定流态可能发生的变化;以及使用优化模型,针对已确定的流态变化制定分配政策。所提议的方法在塞内加尔河流域进行了测试,该流域在过去经历了多年干旱、正常和潮湿时期。对分配政策的分析凸显了气候定制政策在适应气候变化方面的相关性,在最极端的变化情况下,气候定制政策会产生适度收益,而在较温和的变化情况下,气候定制政策仍然有意义。

Nepal has more than a decade of experience in formulating and implementing climate change policies, plans, frameworks, and institutional mechanisms for local adaptation. Drawing upon this experience, this research aims to elucidate the existing policies, institutional commitments and capacity that underpin local adaptation. Furthermore, it seeks to delineate the mechanism through which these commitments are translated into action fostering empowerment of poor and vulnerable communities for locally led adaptation (LLA). Our research involved a comprehensive review of major policies and legal and procedural documents related to climate change adaptation. We analyzed Local Adaptation Plans for Action (LAPA), carried out in-depth interviews with frontline actors and a participant observation and focus group discussions with LAPA communities. The research features that despite a strong policy commitment, adaptation in Nepal is struggling with institutional barriers, contested interest between key authorities, limited capacity, and unequal distribution of resources to support LLA. The LAPA analysis shows the priorities and investment plans are mostly intended to continue business as usual practices addressing bio-physical and natural hazards rather than properly understanding and addressing underlying, pre-existing, and structural causes of vulnerabilities. Notwithstanding the established evidence about differential impacts of climate change, the response mechanisms have exhibited limited realization of this knowledge. Future trajectory of LLA in Nepal hinges on the proactive efforts of the government to reform institutional and fund flow mechanisms, capacity, commitment, and a changing mindset for the devolution of decision making at the local level and making a substantial progress in climate financing.

尼泊尔在制定和实施气候变化政策、计划、框架和地方适应体制机制方面已有十多年的经验。借鉴这些经验,本研究旨在阐明支持地方适应的现有政策、制度承诺和能力。此外,本研究还试图阐明将这些承诺转化为行动的机制,以促进贫困和弱势社区在地方主导的适应行动(LLA)中的赋权。我们的研究涉及对与气候变化适应相关的主要政策、法律和程序文件的全面审查。我们分析了地方适应行动计划(LAPA),对一线行动者进行了深入访谈,并对 LAPA 社区进行了参与观察和焦点小组讨论。研究结果表明,尽管尼泊尔做出了强有力的政策承诺,但在支持地方适应行动计划方面,尼泊尔仍面临着体制障碍、主要政府部门之间的利益争夺、能力有限以及资源分配不均等问题。适应行动方案分析表明,优先事项和投资计划大多旨在继续一切照旧地应对生物物理和自然灾害,而不是正确理解和解决造成脆弱性的根本原因、先前存在的原因和结构性原因。尽管已有证据表明气候变化会产生不同的影响,但应对机制对这一知识的认识却十分有限。尼泊尔 LLA 的未来发展轨迹取决于政府为改革体制和资金流动机制所做的积极努力、能力、承诺以及在地方一级下放决策权和在气候融资方面取得实质性进展的思想转变。

Urban green space (UGS) offers users multiple ecosystem services and amenities. This study investigated whether residents used UGS visitation in summer as a sustainable measure to tackle hot weather and associated climate-change impacts in humid-subtropical Hong Kong. Attributes of the indoor residential environment, seldom examined in park-visitation studies, were evaluated as push factors to visit UGS through a push–pull theoretical framework. A questionnaire survey of 483 respondents targeted urban park users. The results indicated that UGS visit frequency and stay duration were relatively low in hot summer. Ordinal multiple regression showed that indoor living conditions, residence location, living routine, and habit and personal health impacts were significantly correlated with UGS visits. Interdependence between push and pull factors was detected, demonstrating that intrinsic UGS environmental conditions could constrain UGS visits despite the motivations of push factors. The results indicated the need to improve the microclimate-regulating function in UGS. It could be achieved mainly by optimizing the nature-based design to promote UGS as an adaptive measure to combat the thermal stress brought by climate change. The findings yielded hints to shape visiting habits and suggestions to improve UGS management.

城市绿地(UGS)为使用者提供多种生态系统服务和便利。本研究调查了香港居民是否将夏季游览城市绿地作为应对炎热天气和相关气候变化影响的可持续措施。室内居住环境的属性在公园游览研究中很少被考察,本研究通过推拉理论框架对室内居住环境的属性进行了评估,将其作为游览城市地质公园的推动因素。问卷调查以城市公园使用者为对象,共有 483 名受访者。结果表明,在炎热的夏季,游览城市公园的频率和停留时间相对较低。正态多元回归显示,室内生活条件、居住地点、生活规律、习惯和个人健康影响与游览公园有显著相关性。推力因素和拉力因素之间存在相互依存关系,这表明尽管存在推力因素的动机,但其内在的环境条件可能会限制人们到访这些地方。研究结果表明,有必要改善城市地质公园的小气候调节功能。这主要可以通过优化以自然为基础的设计来实现,以促进 UGS 成为应对气候变化带来的热压力的适应性措施。研究结果还为培养游客的游览习惯提供了提示,并为改善城市地质公园的管理提出了建议。
