To address escalating health risk posed by extreme weather due to climate change, it’s particularly important to identify tailored adaptation measures for various actors, enabling them to respond quickly and effectively. However, there remains a lack of clarity on the specific and comprehensive actions each actor should take. This study first establishes an adaptation action framework to delineate a pathway for implementing adaptation measures, encompassing integrated monitoring, risk assessment, risk warning, policy response, effectiveness evaluation, and capacity building. Within this framework, the study identifies practical adaptation action lists tailored to various actors---governments, healthcare facilities, communities, and individuals. These actions include establishing multisectoral coordination mechanisms, conducting health risk assessments, promoting telemedicine, utilizing wearable health devices, and more. Furthermore, this study reviews the progress of adaptations to health risks associated with climate change, revealing that national and regional adaptation plans are increasingly being implemented, early warning systems are becoming more precise and informative, and adaptation knowledge-sharing initiatives are continuously evolving and innovating. However, three significant challenges persist in areas such as intersectoral collaboration, awareness gaps, and insufficient financing. Overall, this study provides a clear path for actors to develop and implementing comprehensive strategies to mitigate the health risks posed by climate change.
为了应对气候变化造成的极端天气带来的不断升级的健康风险,特别重要的是为各种行为者确定量身定制的适应措施,使他们能够迅速有效地作出反应。然而,各方应采取的具体和全面行动仍不明确。本研究首先建立了一个适应行动框架,描绘了实施适应措施的途径,包括综合监测、风险评估、风险预警、政策响应、有效性评估和能力建设。在这一框架内,该研究确定了适合政府、医疗机构、社区和个人等不同行为体的实际适应行动清单。这些行动包括建立多部门协调机制、开展健康风险评估、促进远程医疗、利用可穿戴保健设备等。此外,本研究回顾了适应与气候变化相关的健康风险的进展,揭示了国家和区域适应计划正在越来越多地得到实施,早期预警系统变得更加精确和信息丰富,适应知识共享举措正在不断发展和创新。然而,在部门间合作、认识差距和资金不足等领域仍然存在三大挑战。总的来说,这项研究为行为体制定和实施减轻气候变化带来的健康风险的综合战略提供了一条明确的途径。

To address the shortcomings of existing research on provincial carbon emission allowance (CEA) allocation regarding connecting the current situation with future trends, balancing provincial development demands with responsibilities, as well as reconciling equity and efficiency, this study proposed a bidirectional CEA allocation method to guide China's 2030 carbon peak goal. Drawing on province-specific characteristics and multiple guiding principles, we designed 961 allocation schemes. An integrated evaluation system combining equity (via the extended Gini coefficient) and efficiency (via the Malmquist index) yielded 18 Pareto-optimal solutions. These schemes achieve a trade-off between equity (Gini coefficient 0.29–0.33) and efficiency (Malmquist index 1.010–1.015). The optimal schemes account for provincial heterogeneity: advanced regions such as Beijing, Shanghai, and Guangdong would reduce emissions below their 2020 levels under ten of the eighteen schemes, whereas regions such as Tianjin, Shanxi, and Shaanxi would still have room for emission growth across all schemes. By offering a suite of trade-off solutions, our approach equips policymakers with the flexibility to prioritize equity or efficiency according to regional needs. Additionally, tailored policy recommendations are outlined for advancing carbon dual-control mechanisms and crafting support measures reflecting provincial characteristics.
针对现有省级碳排放配额分配研究在联系现状与未来趋势、平衡省级发展需求与责任、协调公平与效率等方面存在的不足,本研究提出了双向碳排放配额分配方法,以指导中国2030年碳峰值目标的实现。根据各省特点和多重指导原则,我们设计了961个分配方案。一个结合公平(通过扩展基尼系数)和效率(通过马尔姆奎斯特指数)的综合评估系统产生了18个帕累托最优解。这些方案实现了公平(基尼系数0.29-0.33)和效率(Malmquist指数1.010-1.015)之间的权衡。最优方案考虑了各省的异质性:北京、上海和广东等发达地区在18个方案中的10个方案下的排放量将低于2020年的水平,而天津、山西和陕西等地区在所有方案下仍有排放增长的空间。通过提供一套权衡解决方案,我们的方法使政策制定者能够灵活地根据地区需要优先考虑公平或效率。此外,为推进碳双重控制机制和制定反映省级特色的支持措施,提出了有针对性的政策建议。

Infrastructure-based heat reduction strategies, such as using cool building materials (high albedo) and street greenery, can be effective methods for cooling cities. However, the effectiveness of different measures on near-surface air temperature and population heat exposure in cities remains unclear. This study used the Weather Research and Forecasting model coupled with the single-layer urban canopy model and conducted one control and four urban adaptation strategy simulations (cool roof, green roof, urban tree and full adaptation) with a convection-permitting scale of 3 km in eastern China during the warm season of 2022. Our findings reveal that these strategies notably decreased 2 m air temperature, with averaged cooling effects of daily air temperature in 37 cities reaching −0.4 °C (cool roof), −0.3 °C (green roof), −0.2 °C (urban tree) and −0.6 °C (full adaptation). The cooling effects in cities illustrated notable regional characteristics; that is, they were stronger in Central China, East China, South China and North China but weaker in Southwest, Northwest and Northeast. Based on the results of multiple linear regression, we attributed the dominant climate factor of each measure: Bowen ratio for cool roof and urban tree and full adaptation and downward shortwave flux for green roof. In addition, urban adaptation strategies greatly reduced extreme heat hours in 37 cities, with averages of 67 (cool roof), 47 (green roof), 22 (urban tree) and 88 h (full adaptation). Furthermore, urban adaptation strategies substantially reduced population heat exposure in populated cities, such as Shanghai (2.48 billion person-h), Guangzhou (1.48 billion person-h), Beijing (1.26 billion person-h) and Shenzhen (1.17 billion person-h). In summary, urban cooling measures can notably decrease air temperature and reduce heat exposure risk during the warm season in cities but vary in their effectiveness in various cities, which highlights the need for region-specific approaches for adaptation to climate change.
基于基础设施的减热策略,如使用凉爽的建筑材料(高反照率)和街道绿化,可以成为冷却城市的有效方法。然而,不同措施对城市近地表气温和人口热暴露的有效性尚不清楚。本研究利用天气研究与预报模型与单层城市冠层模型耦合,在2022年暖季中国东部地区进行了1个对照和4个城市适应策略(冷屋顶、绿屋顶、城市树和完全适应)模拟,模拟尺度为3 km,允许对流。我们的研究结果表明,这些策略显著降低了2米的气温,37个城市的平均日气温降温效果达到- 0.4°C(冷屋顶)、- 0.3°C(绿色屋顶)、- 0.2°C(城市树木)和- 0.6°C(完全适应)。城市降温效应呈现显著的区域特征;即华中、华东、华南和华北偏强,西南、西北和东北偏弱。基于多元线性回归的结果,我们将各措施的主导气候因子归为:冷屋顶和城市树木的Bowen比和绿色屋顶的完全适应和向下短波通量。此外,城市适应策略显著减少了37个城市的极端热小时,平均为67 h(冷屋顶)、47 h(绿色屋顶)、22 h(城市树)和88 h(完全适应)。此外,城市适应策略显著降低了人口密集城市的人口热暴露,如上海(24.8亿人h)、广州(14.8亿人h)、北京(12.6亿人h)和深圳(11.7亿人h)。总之,城市降温措施可以显著降低城市温暖季节的气温和热暴露风险,但其有效性在不同城市有所不同,这突出了适应气候变化的区域具体方法的必要性。

The development of climate-adaptive migration corridors has emerged as a key strategy for biodiversity conservation. However, most existing studies focus on the migration patterns and adaptability of a few species and barely pay attention to the design of migration corridors that address multispecies needs at a national scale under climate change. In this study, we analysed 1023 nationally protected wildlife species in China to predict their potential distributions under current climatic conditions and the SSP2-4.5 scenario using the maximum entropy model. The projections were used as a base to conduct hotspot analysis to identify areas with declining, stable or increasing habitat selection rates (HSRs), which were designated as ecological sources. These areas correspond to regions likely to experience species emigration, retention or immigration. Using circuit theory and the minimum cumulative resistance model, we employed the Linkage Mapper tool to construct climate-resilient conservation corridors and identify critical ecological nodes. We identified 49 ecological sources, including 19 ecological sources with declining HSRs, 13 ecological sources with stable HSRs and 17 ecological sources with increasing HSRs. These HSRs collectively covered over 90% of the studied species and demonstrated a strong conservation representativeness. We also mapped 108 migration corridors, including 49 supporting species movement from areas with declining HSRs and 59 enhancing connectivity and species exchange. In addition, we identified 978 ecological pinch points and 203 barrier points, which are critical priorities for future corridor planning. A novel framework for the design of multispecies conservation corridors that support climate change adaptation, which contributes to China's efforts to achieve the Kunming–Montreal Biodiversity Framework targets and improve ecosystem connectivity.
气候适应性迁移走廊的发展已成为生物多样性保护的一项关键战略。然而,现有的研究大多集中在少数物种的迁移模式和适应性上,很少关注气候变化下全国范围内多物种迁移通道的设计。本文以中国1023种国家级保护野生动物为研究对象,利用最大熵模型预测了它们在当前气候条件和SSP2-4.5情景下的潜在分布。以预测结果为基础,进行热点分析,确定生境选择率下降、稳定或增加的区域,并将其指定为生态源。这些区域对应于可能经历物种迁移、保留或迁移的区域。基于电路理论和最小累积阻力模型,利用Linkage Mapper工具构建了气候适应性保护廊道,并确定了关键生态节点。共鉴定出49个生态源,其中高通量下降的生态源19个,高通量稳定的生态源13个,高通量增加的生态源17个。这些高通量保护区覆盖了90%以上的研究物种,具有较强的保护代表性。我们还绘制了108条迁徙通道,其中49条支持高铁覆盖率下降地区的物种迁移,59条促进物种交流和连通性。此外,我们还确定了978个生态点和203个屏障点,这些点是未来走廊规划的关键优先事项。支持气候变化适应的多物种保护走廊设计新框架,为中国实现《昆明-蒙特利尔生物多样性框架》目标和改善生态系统连通性做出贡献。

Marine cloud brightening (MCB) has been proposed as a backup method to mitigate some impacts of global warming. Cloud albedo can be increased over ocean or land either intentionally or unintentionally. Our understanding of how the climate response differs between cloud albedo enhancement over ocean and land remains limited. In this study, we use the Community Earth System Model (CESM) to explore the impact of cloud albedo enhancement over either ocean or land on the terrestrial climate and carbon cycle. In our simulation design, both MCB and land cloud brightening (LCB) are applied over the latitude bands of 30°S‒30°N under atmospheric CO2 concentration of 800 × 10−6 to achieve a net negative radiative forcing of about −1 W/m2. Over large parts of the low latitude land, MCB increases precipitation by enhancing upward atmospheric motion, resulting in increased soil moisture. In contrast, LCB decreases precipitation by inducing subsidence, resulting in decreased soil moisture. Changes in climatic factors affect land gross primary production (GPP). Relative to the high CO2 world, LCB reduces GPP by 3.80 ± 0.09 GtC per year, which is about three times the reduction caused by MCB (1.34 ± 0.10 GtC per year). These differences in GPP responses are closely linked to changes in the hydrological cycle. In large parts of low-latitude regions, MCB increases soil moisture, which acts to enhance GPP. Conversely, LCB reduces soil moisture, which acts to suppress GPP. MCB and LCB-induced changes in temperature, sunlight, and vapor pressure deficit also play important roles in regulating GPP change. This study would help us to better understand terrestrial climate and carbon cycle consequences resulting from large-scale cloud albedo change over either ocean or land, as well as large-scale albedo change over ocean and land surface.
海洋云增亮(MCB)已被提出作为缓解全球变暖影响的备用方法。云的反照率会有意或无意地在海洋或陆地上增加。我们对气候反应在海洋和陆地云层反照率增强之间的差异的理解仍然有限。在本研究中,我们使用群落地球系统模型(CESM)来探讨海洋和陆地云层反照率增强对陆地气候和碳循环的影响。在我们的模拟设计中,在大气CO2浓度为800 × 10 - 6的情况下,在30°S-30°N的纬度带上施加MCB和陆地云增亮(LCB),可实现约为- 1 W/m2的净负辐射强迫。在大部分低纬度地区,MCB通过增强大气向上运动来增加降水,导致土壤湿度增加。相反,LCB通过诱导沉降减少降水,导致土壤湿度降低。气候因子的变化影响土地初级生产总值(GPP)。相对于高CO2世界,LCB每年使GPP减少3.80±0.09 GtC,约为MCB(1.34±0.10 GtC /年)的3倍。这些GPP响应的差异与水文循环的变化密切相关。在大部分低纬度地区,MCB增加了土壤水分,从而增强了GPP。相反,LCB降低土壤水分,抑制GPP。MCB和lcb诱导的温度、日照和蒸汽压亏缺变化也对GPP的变化起重要调节作用。这项研究将有助于我们更好地了解海洋或陆地大尺度云层反照率变化以及海洋和陆地表面大尺度反照率变化所导致的陆地气候和碳循环后果。

Provincial carbon emission reduction performance (CERP) evaluation is crucial for China's climate change mitigation efforts. However, existing research lacks an in-depth exploration of the conditions and mechanisms enhancing provincial CERP. This study evaluates provincial CERP during the 13th Five-Year Plan (FYP) period in China using a comprehensive evaluation method and identifies four antecedent conditions influencing CERP based on provincial policy practices: industrial structure adjustment, energy efficiency improvement, energy structure optimization, and supporting mechanisms enhancement. Using the qualitative comparative analysis (QCA) method, this study reveals the complex causal mechanisms driving provincial CERP: 1) single conditions are insufficient to determine high/low CERP, as it results from the co-movement of multiple conditions; 2) there are multiple pathways to achieve high CERP, each requiring the interaction of multiple conditions; 3) different types of provinces have different pathways to high CERP. Specifically, resource-abundant provinces have two pathways to high CERP, where substantial optimization of energy structure is necessary.

省级碳减排绩效评价对中国的气候变化减缓工作至关重要。然而,现有的研究缺乏对提高省级企业竞争力的条件和机制的深入探索。本文采用综合评价方法对“十三五”期间中国省级能源生产效率进行了评价,并结合省级政策实践,确定了产业结构调整、能效提升、能源结构优化和配套机制完善四个影响能源生产效率的前因条件。采用定性比较分析(QCA)方法,研究揭示了影响省级经济产出效率的复杂因果机制:1)单一条件不足以决定经济产出效率的高低,它是多种条件共同作用的结果;2)实现高CERP有多种途径,每种途径都需要多种条件的相互作用;3)不同类型省份的高CERP路径不同。具体而言,资源丰富的省份有两条通往高CERP的路径,需要对能源结构进行实质性优化。资源匮乏省份有三条通往高CERP的途径,需要大幅提高能源效率;4)通往低CERP的多条通路均与通往高CERP的通路不对称相关。这些发现强调了实现高CERP的不同途径,为不同省份提供了量身定制的减排策略。

Climate change-induced range shifts in species pose a profound challenge to biodiversity conservation. China has recently updated its list of key protected species, encompassing 980 wildlife species and 455 plant species. However, the potential impacts of climate change on the distribution patterns of these species remain unclear, inevitably hindering the formulation of effective and adaptive conservation strategies. This study combines species distribution models with gap analysis to examine the negative and positive impacts of climate change on 1023 key protected species. We assessed species extinction risks, identified conservation gaps and effectiveness, and proposed adaptive strategies to mitigate the impacts of climate change. Our findings indicate that under the SSP1-2.6, SSP2-4.5, and SSP5-8.5 scenarios, 5, 28, and 83 species, respectively, would face high extinction risks with universal dispersal by the end of the 21st century. Plants generally exhibit higher habitat loss rates and extinction risks than animals. Among animal taxa, amphibians exhibit the highest extinction risks and habitat loss rates, with notably lower habitat gain and habitat remain rates compared to other groups. Geographically, species in Central China and Northeast China are at the highest risk of extinction, whereas the Qinghai‒Xizang Plateau, Northwest China, and South China experience relatively lower risks. Although the current protected area network provides adequate coverage for the majority of target species, a notable conservation gap (>25%) persists for 115 species. Under the SSP1-2.6, SSP2-4.5, and SSP5-8.5 scenarios with universal dispersal, the average species turnover rates within protected areas are 36.29%, 43.29%, and 51.10%, respectively, by the end of the 21st century. This study highlights the need for dynamic conservation and adaptation strategies in the context of climate change, offering essential insights for achieving the 30 × 30 conservation target and developing long-term effective adaptation strategies.
气候变化引起的物种范围变化对生物多样性保护提出了深刻的挑战。中国最近更新了重点保护物种名录,包括980种野生动物和455种植物。然而,气候变化对这些物种分布格局的潜在影响尚不清楚,不可避免地阻碍了有效和适应性保护策略的制定。采用物种分布模型和差异分析相结合的方法,研究了气候变化对1023种重点保护物种的影响。我们评估了物种灭绝风险,确定了保护差距和有效性,并提出了缓解气候变化影响的适应策略。结果表明,到21世纪末,在SSP1-2.6、SSP2-4.5和SSP5-8.5情景下,分别有5个、28个和83个物种面临高灭绝风险,物种将普遍扩散。植物通常比动物表现出更高的栖息地丧失率和灭绝风险。在动物类群中,两栖动物的灭绝风险和栖息地丧失率最高,其栖息地获得率和栖息地保留率明显低于其他类群。从地理上看,中国中部和东北地区物种灭绝风险最高,而青藏高原、西北和华南地区物种灭绝风险相对较低。虽然目前的保护区网络为大多数目标物种提供了足够的覆盖,但仍有115种物种存在显著的保护缺口(25%)。在SSP1-2.6、SSP2-4.5和SSP5-8.5普遍扩散情景下,到21世纪末,保护区内的平均物种周转率分别为36.29%、43.29%和51.10%。该研究强调了气候变化背景下动态保护和适应策略的必要性,为实现30 × 30保护目标和制定长期有效的适应策略提供了重要见解。

Recent discoveries of perennial retained meltwater, firn aquifers (FA), in the firn layer of Wilkins Ice Shelf (WIS) and Greenland Ice Sheet (GrIS) have significantly enhanced our understanding of surface hydrological processes and mass and energy balances. However, limited field and airborne radar observations cannot provide a comprehensive picture of the distribution and characteristics of these aquifers. The dominative factors for FA formation (including surface snowmelt and snow accumulation) can be effectively captured by microwave remote sensing, which offers the possibility of linking FA burial depth with remote sensing data. In this study, the extent and depth to water table (DWT) of FA are investigated through the integration of multi-source microwave observations and airborne radar measurements. Using verification points from airborne radar, the extent of FA is first mapped based on satellite-derived snowmelt and accumulation variables using a K-Nearest Neighbors classification model. Subsequently, a Gaussian Process Regression model is used to estimate the DWT of FA, achieving correlation coefficients of 0.9 for the WIS and 0.73 for the GrIS. Furthermore, the FA exhibited a distinct concentration in the southeastern and southern basins of the GrIS, where a DWT of 22 ± 5 m. The temporal evolution of FA, including both spatial extent and vertical buried depth, requires ongoing monitoring to evaluate their potential impacts on englacial environment and the stability of ice sheet.
最近在威尔金斯冰架(WIS)和格陵兰冰盖(GrIS)的冰冻层中发现了常年保留的融水,即冰冻含水层(FA),这大大增强了我们对地表水文过程和质量和能量平衡的理解。然而,有限的实地和机载雷达观测不能提供这些含水层的分布和特征的全面图像。微波遥感可以有效地捕获积雪形成的主导因素(包括地表融雪和积雪),为将积雪埋藏深度与遥感数据联系起来提供了可能。本研究通过多源微波观测和机载雷达测量相结合的方法,研究了多源微波观测对地下水位的影响程度和深度。利用机载雷达的验证点,首先使用k -最近邻分类模型基于卫星衍生的融雪和积累变量绘制FA的范围。随后,使用高斯过程回归模型估计FA的DWT, WIS的相关系数为0.9,GrIS的相关系数为0.73。此外,FA在GrIS的东南部和南部盆地表现出明显的集中,其DWT为22±5 m。冰川消融的时间演变(包括空间范围和垂直埋藏深度)需要持续监测,以评估其对冰川环境和冰盖稳定性的潜在影响。

Two-phase closed thermosyphons (TPCTs) is widely used in the Qinghai‒Tibet Highway (QTH) due to the excellent cooling efficiency. However, affected by the complex environment, climate warming and the strong heat absorption of asphalt pavement, diseases still exist in the embankments with TPCTs. Taking 31 sections of embankments with TPCTs along the QTH as the objects, we abstained the deformation law by adopting the Small Baseline Subset-Interferometric Synthetic Aperture Radar (SBAS-InSAR), and the influence of complex environment is evaluated. The results show that the average annual deformation rate of these 31 embankments with TPCTs is −4.077 ± 1.979 mm per year, and it is influenced by orientation, elevation, soil type, ice content, mean annual ground temperature, and TPCTs installing form. The main diseases are longitudinal cracking, transverse cracking and differential settlement. Longitudinal cracking mainly caused by uneven temperature distribution tends to occur in multiple lines on embankment with inclined TPCTs, while it appears as a single line on embankment with vertical TPCTs. Related to the uneven temperature distribution, fatigue damage caused by repeated freezing‒thawing action, traffic load and water infiltration, transverse cracking typically occurs in the high-temperature area between two adjacent TPCTs. The TPCTs installing form and the shady‒sunny slope effect promote the differential settlement. Severe differential settlement tends to occur from the sunny slope shoulder to the center of half pavement at sunny side on the embankments with inclined TPCTs, while less severe differential settlement is likely to occur from the sunny side to embankment center on the embankment with vertical TPCTs. These results are crucial for improving our understanding of the disease characteristics and mechanism of embankment with TPCTs in permafrost regions and ensuring long-term service safety for the Qinghai‒Tibet Highway.
然而,受环境复杂、气候变暖和沥青路面吸热性强的影响,铺有tpct的路堤仍存在病害。采用小基线亚集干涉合成孔径雷达(SBAS-InSAR),以QTH沿线31段有tpct的路堤为研究对象,对其变形规律进行了反演,并对复杂环境的影响进行了评价。结果表明:31个加装tpct路堤的年平均变形速率为- 4.077±1.979 mm /年,其变形速率受路向、高程、土壤类型、含冰量、年平均地温和tpct安装形式的影响;主要病害有纵向开裂、横向开裂和差异沉降。纵向裂缝主要由温度分布不均匀引起,在倾斜tpct的路堤上往往出现多条裂缝,而在垂直tpct的路堤上则表现为单线裂缝。由于温度分布不均匀、反复冻融作用引起的疲劳损伤、交通荷载和渗水等因素,相邻两个tpct之间的高温区通常发生横向开裂。tpct的安装形式和阴晴坡效应促进了差异沉降。倾斜tpct路堤向阳侧向阳坡肩至半路面中心容易发生严重的差异沉降,而垂直tpct路堤向阳侧至路堤中心可能发生不太严重的差异沉降。

The Paris Agreement mandates that countries report on their adaptation efforts to evaluate the adequacy and effectiveness of these measures. Agriculture, a critical sector in climate change adaptation, benefits significantly from global case studies that provide evidence, share experiences, and disseminate knowledge. However, the rapid expansion of these case studies presents challenges in extracting and analyzing relevant information effectively. To address this, this study developed a question‒answering information extraction framework that combines geographic analysis with ChatGPT. Guided by the Systematic Evidence Synthesis (ROSES) review protocol, we established a comprehensive global database of agricultural adaptation cases from 2000 to 2024. This database includes key information such as case distribution, climate stressors, adaptation measures, cost-effectiveness, and constraints, aimed at identifying major trends in agricultural adaptation. Our findings reveal the following: 1) Natural language processing technologies, particularly Large Language Models (LLMs), greatly enhance the efficiency and depth of extracting key information from adaptation cases. This advancement supports the frequent updating of the agricultural adaptation database. 2) There is a notable geographic imbalance in agricultural adaptation efforts globally. Adaptation cases are concentrated in central and southern Africa, southern Asia, Europe, and other regions. While there is diversity in responses to slow onset events, measures for extreme climate events are less common, indicating a gap in the sector's ability to address sudden and uncertain challenges. 3) Agricultural adaptation measures are evolving from individual technologies to more comprehensive approaches. The shift is from methods like crop improvement and irrigation adjustments to integrated measures such as climate-smart agriculture, conservation agriculture, and sustainable practices. These approaches collectively enhance adaptation capacity through technological, managerial, infrastructural, and biodiversity improvements, reflecting a deeper understanding and ongoing refinement of adaptation practices. This study highlights the significant potential of LLMs in improving the efficiency of information extraction and analysis for global adaptation research. It offers new methods for quickly summarizing adaptation cases in agriculture and potentially other fields, providing valuable insights and recommendations for global agricultural policymakers.
《巴黎协定》要求各国报告其适应努力,以评估这些措施的充分性和有效性。农业是适应气候变化的关键部门,它从提供证据、分享经验和传播知识的全球案例研究中受益匪浅。然而,这些案例研究的迅速扩展对有效提取和分析相关信息提出了挑战。为了解决这个问题,本研究开发了一个将地理分析与ChatGPT相结合的问答信息提取框架。在系统证据综合(ROSES)审查方案的指导下,我们建立了2000 - 2024年全球农业适应案例综合数据库。该数据库包括病例分布、气候压力源、适应措施、成本效益和制约因素等关键信息,旨在确定农业适应的主要趋势。研究结果表明:1)自然语言处理技术,特别是大语言模型(llm),极大地提高了自适应案例关键信息提取的效率和深度。这一进展支持了农业适应数据库的频繁更新。2)全球农业适应努力存在显著的地域不平衡。适应案例集中在非洲中部和南部、南亚、欧洲和其他地区。虽然对缓慢发生的气候事件的应对措施多种多样,但针对极端气候事件的措施并不常见,这表明该行业应对突发和不确定挑战的能力存在差距。3)农业适应措施正在从单个技术向更综合的方法发展。这种转变是从作物改良和灌溉调整等方法转向气候智慧型农业、保护性农业和可持续实践等综合措施。这些方法通过技术、管理、基础设施和生物多样性的改进共同增强了适应能力,反映了对适应实践的更深入理解和不断改进。本研究强调了llm在提高全球适应研究的信息提取和分析效率方面的巨大潜力。它提供了快速总结农业和潜在的其他领域适应案例的新方法,为全球农业决策者提供了有价值的见解和建议。
