Severe hailstorms are among the most destructive weather phenomena in Europe, with the recent hail seasons of 2022 and 2023 both causing record losses above 5 billion euros. This highlights the importance of assessing hail risk in a warming climate. We approach this question by leveraging 11-year convection-resolving climate simulations using the COSMO model with the hail growth module HAILCAST. Comparing a 3 °C warming scenario to present-day simulations, we observe a generally increasing trend in expected hail damage to buildings, with a 42% increase over the calibration region in Switzerland and pronounced spatial variability across Europe. Assuming a building vulnerability as calibrated over Switzerland, 24 of 28 countries show an increasing potential for hail damage, despite only 11 with increasing overall hail frequency. Given the concentration of hail damages into few events with limited spatial extent, we observe a large variability in modelled hail damage based on sampling uncertainty within the 11-year simulations, which locally mostly exceeds the change signal. Larger spatial aggregation increases the confidence in the climate change signal, with the overall damage potential over Europe increasing by 25%–42% in the 3 °C warming scenario. On top of the change signal, we provide a spatially resampled hail event set for explicit risk assessments and a new technique to calibrate impact functions for climate simulations to observed data.
严重的冰雹是欧洲最具破坏性的天气现象之一,最近的2022年和2023年的冰雹季节都造成了超过50亿欧元的创纪录损失。这突出了在气候变暖的情况下评估冰雹风险的重要性。我们通过利用COSMO模式和冰雹增长模块HAILCAST进行11年对流解析气候模拟来解决这个问题。将3°C变暖情景与目前的模拟进行比较,我们观察到预期冰雹对建筑物造成的破坏总体呈增加趋势,在瑞士的校准区域增加42%,整个欧洲的空间变异性明显。假设建筑物的脆弱性以瑞士为基准,28个国家中有24个国家显示出冰雹破坏的可能性增加,尽管只有11个国家的冰雹总体频率增加。考虑到冰雹灾害集中在有限空间范围内的几个事件中,我们观察到11年模拟中基于采样不确定性的冰雹灾害模型存在很大的变化,局部变化大多超过了变化信号。更大的空间聚集增加了对气候变化信号的信度,在3°C变暖情景下,欧洲的总体破坏潜力增加了25%-42%。在变化信号的基础上,我们提供了一个空间重采样的冰雹事件集,用于明确的风险评估,并提供了一种新的技术来校准气候模拟对观测数据的影响函数。

Growing population exposure to extreme floods in the Pearl River Basin in the future under global warming levels 在全球变暖的背景下,未来珠江流域越来越多的人口面临极端洪水的威胁
IF 4.5 3区 环境科学与生态学 Q2 ENVIRONMENTAL SCIENCES Pub Date : 2026-01-01 Epub Date: 2026-01-09 DOI: 10.1016/j.cliser.2025.100632

Climate change and socioeconomic development are projected to change flood risk in China’s Pearl River Basin (PRB), yet the future pathways of this risk remain unclear. This study quantifies population exposure to extreme floods from 1985 to 2100 by integrating a basin-calibrated WEB-DHM-SG hydrological model with bias-corrected ISIMIP3b climate projections and Shared Socioeconomic Pathway (SSP126, SSP370, SSP585) population datasets. We assess exposure at global warming thresholds from 1.5 °C to 4.5 °C and decompose the contributions of climatic versus demographic drivers. Results indicate that population exposure peaks around mid-century at approximately 20 million people across all scenarios, then diverges: it declines under SSP126 (to ∼ 18 million), rises under SSP370 (to ∼ 22.5 million), and stabilizes under SSP585 (near ∼ 20 million). Sensitivity analysis reveals that each additional half-degree of warming increases the exposed population by ∼ 2.8 × 105 (1.8 %) and raises the exposure share by ∼ 0.36 %. Climate change drives approximately 80 % of the basin-wide exposure increase, while local population dynamics—particularly in the Pearl River Delta—account for over one-fifth of the rise above 3 °C. The Dongjiang River and lower Xijiang River are identified as persistent hotspots, whereas sections of the Beijiang River exhibit relative resilience. These findings underscore the necessity of low-emission pathways and risk-informed adaptation strategies to mitigate future exposure.
预计气候变化和社会经济发展将改变中国珠江流域的洪水风险,但这种风险的未来路径尚不清楚。本研究通过整合流域校准的WEB-DHM-SG水文模型、偏差校正的ISIMIP3b气候预测和共享社会经济路径(SSP126、SSP370、SSP585)人口数据集,量化了1985年至2100年极端洪水的人口暴露程度。我们评估了在1.5°C至4.5°C的全球变暖阈值下的暴露情况,并分解了气候和人口驱动因素的贡献。结果表明,在所有情景下,人口暴露在本世纪中叶左右达到峰值,约为2000万人,然后出现分化:在SSP126下下降(至~ 1800万),在SSP370下上升(至~ 2250万),在SSP585下稳定(接近~ 2000万)。敏感性分析表明,温度每增加半度,暴露人口增加~ 2.8 × 105(1.8%),暴露比例增加~ 0.36%。气候变化导致了大约80%的流域暴露增加,而当地人口动态-特别是珠江三角洲-占了超过五分之一的3°C以上的上升。东江和西江下游被确定为持续的热点,而北江部分地区则表现出相对的弹性。这些发现强调了采用低排放途径和风险知情的适应策略来减轻未来暴露的必要性。

A climate indicator dashboard for communicating climate change in the Okanagan Valley of B.C. 在不列颠哥伦比亚省的奥肯那根山谷,一个气候指示仪表板,用于传达气候变化

The Okanagan Valley in British Columbia, Canada, is increasingly vulnerable to climate change, experiencing hotter temperatures, longer and more intense wildfire seasons, extreme cold events, long-term droughts, and less predictable water supplies. Communities now often experience multiple climate-driven extreme events within the same year. Therefore, the Okanagan Basin Water Board (OBWB), a regional water resource management body, recognized the need to support regional decision-makers with effective tools to integrate local climate context into community-scale planning and communication. However, climate change is complex and regional decision makers are not trained climate experts. An effective decision support tool must therefore provide accurate and relevant information in a transparent and intuitive way. Motivated by this need, this study describes scientific methods and design principles used to calculate, visualize and present over 30 locally relevant indicators developed from publicly available weather and climate observation data on the publicly available OBWB Climate Indicators Dashboard. The process involved identifying useful climate impact indicators, understanding available data sets and their limitations, understanding and building trust with the intended audience, and iterating on data visualization design and dashboard wording for maximum impact. By presenting our methods and design principles, we highlight the OBWB Climate Indicators Dashboard as one among an emerging class of community-scale tools to communicate climate change. Based on initial positive feedback of the tool, we hope our case study is useful to others planning to create their own watershed-scale climate communication tools.
加拿大不列颠哥伦比亚省的奥肯那根山谷越来越容易受到气候变化的影响,它经历着更高的温度、更长更强烈的野火季节、极端寒冷事件、长期干旱和更不可预测的供水。社区现在经常在同一年内经历多次气候驱动的极端事件。因此,奥肯纳根流域水务局(OBWB),一个区域水资源管理机构,认识到有必要为区域决策者提供有效的工具,将当地气候背景整合到社区规模的规划和沟通中。然而,气候变化是复杂的,区域决策者并不是受过训练的气候专家。因此,有效的决策支持工具必须以透明和直观的方式提供准确和相关的信息。受这一需求的推动,本研究描述了用于计算、可视化和呈现30多个当地相关指标的科学方法和设计原则,这些指标是从公开可用的OBWB气候指标仪表板上公开可用的天气和气候观测数据中开发出来的。该过程包括确定有用的气候影响指标,了解可用数据集及其局限性,了解目标受众并与之建立信任,以及迭代数据可视化设计和仪表板措辞以实现最大影响。通过介绍我们的方法和设计原则,我们强调OBWB气候指标仪表板是新兴的社区规模的气候变化沟通工具之一。基于该工具最初的积极反馈,我们希望我们的案例研究对其他计划创建自己的流域尺度气候通信工具的人有用。

On the importance of the reference data: Uncertainty partitioning of bias-adjusted climate simulations over eastern Canada 参考数据的重要性:加拿大东部经过偏差调整的气候模拟的不确定性划分

Bias-adjusted climate simulations are increasingly disseminated through online platforms to support adaptation actions. However, there is no consensus on an operational framework to choose what to include in these “decision-ready” ensembles and for communicating the related uncertainty. In this paper, we use a systematic approach to assess the uncertainty related to bias-adjusted climate simulations across five dimensions: internal variability, greenhouse gases scenario, global climate model, observational reference and bias-adjustment method. We calculate the fraction of uncertainty associated with each dimension for precipitation-based, temperature-based and multivariate indicators over eastern Canada and focus particularly on three locations: Montréal, Gaspé and Kawawachikamach. The results show that the uncertainty associated with the reference dataset can be very large and in some instances can become the first or second largest source of uncertainty. Using simple examples, we show that the resulting differences could lead to different conclusions with respect to some adaptation solutions or possibly create confusion with users. These results raise questions on the robustness of climate projections distributed through these web platforms and the ethical responsibility of data providers to adequately evaluate and communicate the underlying uncertainty.
偏差调整后的气候模拟越来越多地通过在线平台传播,以支持适应行动。然而,对于选择在这些“准备好决策”的集合中包含什么以及沟通相关不确定性的操作框架,并没有达成共识。本文采用系统方法,从内部变率、温室气体情景、全球气候模式、观测参考和偏倚调整方法五个维度评估了与偏倚调整气候模拟相关的不确定性。我们计算了加拿大东部地区基于降水、基于温度和多变量指标的每个维度的不确定性的比例,并特别关注三个地点:montrsamal、gasaspee和Kawawachikamach。结果表明,与参考数据集相关的不确定性可能非常大,在某些情况下可能成为不确定性的第一或第二大来源。通过简单的例子,我们表明,由此产生的差异可能导致对某些适应解决方案的不同结论,或者可能对用户造成混淆。这些结果对通过这些网络平台发布的气候预测的稳健性以及数据提供者充分评估和传达潜在不确定性的道德责任提出了质疑。

极端高温是致命的,低收入、少数民族和边缘化社区成员尤其容易遭受极端高温。供暖从业者面临着双重挑战,既要采取行动减轻当地居民的高温水平,又要让社区做好准备,应对不可避免的升温水平。由于缺乏关于热量从业者需求的深入信息,这项工作旨在提高我们对如何努力改善气候服务可能有助于美国更有效的极端热量规划和决策的理解。通过采用小组访谈和调查的两轮混合方法,我们与来自40个州和华盛顿特区的144名供热从业人员进行了接触。我们发现,极端高温规划和实施的最大障碍是缺乏对风险的感知和内部人员能力的缺乏,从业者希望获得更多与高温相关的信息和工具。受访者认为最具影响力的两个从业者“需求”是:定期更新本地极端高温数据收集,以及改进极端高温如何影响不同系统的信息。我们发现,根据受访者来自农村还是城市地区,以及他们的受教育程度,干预措施的感知影响存在显著差异。气候引起的极端高温是致命的,对低收入、少数民族和边缘化社区成员的影响尤为严重。地方和地区政府的工作人员负责制定决策和实施行动,以减少极端高温对社区的影响。负责这项工作的人在这里被称为热从业者。为了了解他们的需求,我们进行了一系列访谈和调查,涉及来自40个州和华盛顿特区的140多名供暖从业者。在本文中,我们分享了我们的发现,这些发现使我们深入了解了那些致力于保护人们免受极端高温侵害的人的气候服务需求。我们工作的一个重要发现是,气候服务不能仅仅是提供更多信息,还需要建立适应能力和支持,以克服复杂的障碍。具体来说,我们认为有必要解决供热从业者所处的困境。此外,通过提高社区内热量的重要性,从业者将更容易管理和减轻这一威胁。我们发现人们强烈要求根据当地情况提供更好的信息。供热从业人员表示,对他们的工作最有影响的是更新当地极端高温数据收集和实地监测。另一个高度本地化的数据需求是关于城市设计与极端高温之间关系的信息。我们还听说,信息应该是关于从业者可以采取的具体行动,以解决这一威胁。一个具体的例子是要求提供关于基于自然的解决办法的相对有效性的信息。热从业人员还指出,信息翻译对他们的工作至关重要。他们特别指出,需要将极端高温与风险联系起来。例如,热从业者认为区域特定的热指数可能具有高水平的影响,这表明需要进行翻译工作。当我们听到“与其给我数据,不如告诉我我能用数据做什么”这样的话时,翻译的必要性也很明显。最后,我们观察到需要针对不同地方的具体情况提供气候服务。在城市地区工作的答复者更有可能表示,额外的信息将对他们的工作产生影响。这种差异可以通过编制更明确地适合农村地区并与农村地区相关的信息来解决。此外,我们观察到研究生学历和本科及以下学历的人的需求不同。这种教育差距可以通过改善受教育机会以及向每一群体提供不同类型的信息来解决。热量从业者在某种程度上被分为那些专注于减轻热量和那些专注于热量管理的人。这可以通过在这两个群体之间架起桥梁来解决,也可以通过开发针对每种类型的热从业者的特定服务来解决。

Climate variability challenges smallholder farmers in sub-Saharan Africa. Farmers need tools to help them adapt, such as climate information services (CIS) to enhance resilience and agricultural productivity. This study investigates farmers’ willingness to pay (WTP) for seasonal CIS in Senegal’s Sédhiou and Tambacounda regions. The research explores regional differences and the role of socioeconomic, psychological, and gender-related factors. Using a mixed-methods approach, we collected data from 708 farmers through probabilistic random sampling. The Becker-DeGroot-Marschak (BDM) mechanism was employed to elicit WTP. Regression and mediation analysis were conducted to assess direct and indirect effects on WTP. The findings reveal an average WTP of 1,560 CFA (2.6 USD) for CIS, with 36.7% of farmers bidding above the market price, suggesting strong demand for CIS. Younger farmers and women showed higher WTP. High production costs and limited access to credit reduced bidding amounts. An experimental information intervention significantly increased bid amounts, highlighting the critical role of awareness in shaping demand. Mediation analysis showed that internal locus of control (LoC) does not significantly mediate WTP, suggesting that farmers’ belief in personal control has little impact on their economic decisions. However, restrictive gender norms negatively mediated WTP, underscoring how gender-based constraints reduce demand for CIS. These findings emphasize the need for targeted policies to promote CIS adoption, including awareness campaigns, behavioral and gender-responsive CIS delivery formats, and affordable financial services. By addressing both economic and behavioral barriers, policymakers can improve resilience and agricultural productivity through improved access to climate information.
气候变化给撒哈拉以南非洲的小农带来了挑战。农民需要帮助他们适应的工具,例如气候信息服务(CIS),以提高抵御能力和农业生产力。本研究调查了塞内加尔ssamdhiou和Tambacounda地区农民购买季节性CIS的支付意愿。该研究探讨了地区差异以及社会经济、心理和性别相关因素的作用。采用混合方法,采用概率随机抽样的方法对708名农户进行数据采集。采用Becker-DeGroot-Marschak (BDM)机制诱发WTP。通过回归分析和中介分析来评估对WTP的直接和间接影响。调查结果显示,独联体的平均WTP为1560非洲法郎(2.6美元),36.7%的农民出价高于市场价格,表明对独联体的需求强劲。年轻农民和妇女WTP较高。高昂的生产成本和有限的信贷渠道减少了投标金额。一项实验性信息干预显著增加了投标金额,突出了意识在塑造需求方面的关键作用。中介分析显示,内部控制点(LoC)对WTP的中介作用不显著,表明农民个人控制信念对其经济决策影响不大。然而,限制性的性别规范对WTP产生了负面影响,强调了基于性别的限制如何减少对CIS的需求。这些调查结果强调需要有针对性的政策来促进独联体的采用,包括提高认识运动,行为和性别敏感的独联体交付形式,以及负担得起的金融服务。通过解决经济和行为障碍,政策制定者可以通过改善获取气候信息的途径来提高抵御力和农业生产率。

Extreme weather events, such as frequent droughts, pose a significant threat to agriculture and livelihoods in countries such as Pakistan, where agriculture, which employs 62 % of the workforce, is heavily dependent on rainfall. In the current study, a climate service has been developed to develop early warnings for agrometeorological drought by applying Seasonal Autoregressive Integrated Moving Average (SARIMA) models to forecast the Standardized Precipitation Index (SPI) across 6- and 12-month intervals. This innovative approach aims to enhance the capacity for anticipating drought conditions, facilitate more effective agricultural management and decision-making in response to potential water scarcity. By using monthly precipitation data collected from 20 sites between 1991 and 2024, a comprehensive assessment of historical drought occurrences and projected seasonal conditions for the agricultural period from 2025 to 2030 and long-term 2–25 to 2050 are conducted. The best-fit SARIMA models demonstrated high accuracy (validation R2 values: 0.86–0.94; RMSE values: 0.31–0.49) across meteorological stations. From 2010 to 2024, the Quetta region experienced 17 months of extreme drought (SPI ≤  − 2.0), indicating that severe droughts were a recurrent phenomenon. Projections for 2025–2030 and 2025–2050, based on historical trends, predict prolonged mild drought conditions (SPI: −1.3 to − 1.7) during the Rabi season in Punjab and Sindh. Balochistan is expected to face severe arid conditions, with the SPI reaching − 2.1 by 2028. The SARIMA model showed high forecasting ability, with Nash-Sutcliffe Efficiency values > 0.81 across all stations, offering useful insights for irrigation planning and crop management. Our research will enable policymakers to forecast yield reductions of 25 %–35 % in drought-prone agrometeorological zones and prioritize resource allocation, providing a vital tool for seasonal risk assessment and serving as an early warning system to help plan climate-smart management practices, promote drought-tolerant crop varieties, and implement high-efficiency irrigation systems, thereby improving the resilience of rain-fed agricultural systems.
极端天气事件,如频繁的干旱,对巴基斯坦等国的农业和生计构成重大威胁,在这些国家,农业雇佣了62%的劳动力,严重依赖降雨。在目前的研究中,已经开发了一个气候服务,通过应用季节自回归综合移动平均(SARIMA)模型来预测标准化降水指数(SPI)在6个月和12个月的间隔来开发农业气象干旱的早期预警。这种创新方法旨在提高预测干旱条件的能力,促进更有效的农业管理和决策,以应对潜在的水资源短缺。利用1991 ~ 2024年20个站点逐月降水资料,对2025 ~ 2030年农业期和长期2 ~ 25 ~ 2050年农业期的历史干旱发生率和季节预测条件进行了综合评价。最佳拟合的SARIMA模型在气象站间具有较高的精度(验证R2为0.86 ~ 0.94,RMSE为0.31 ~ 0.49)。2010 - 2024年,Quetta地区经历了17个月的极端干旱(SPI≤- 2.0),表明严重干旱是一种经常性现象。根据历史趋势对2025-2030年和2025-2050年的预测,旁遮普和信德省拉比季将出现长期轻度干旱(SPI: - 1.3至- 1.7)。预计俾路支省将面临严重的干旱条件,到2028年SPI将达到- 2.1。SARIMA模型显示出较高的预测能力,所有站点的Nash-Sutcliffe效率值为0.81,为灌溉规划和作物管理提供了有用的见解。我们的研究将使政策制定者能够预测干旱易发农业气象区减产25% - 35%,并确定资源分配的优先顺序,为季节性风险评估提供重要工具,并作为早期预警系统,帮助规划气候智能型管理实践,推广耐旱作物品种,实施高效灌溉系统,从而提高雨养农业系统的恢复能力。

Weather and climate information services for pastoralists: A review 牧民天气和气候信息服务综述
IF 4.5 3区 环境科学与生态学 Q2 ENVIRONMENTAL SCIENCES Pub Date : 2025-12-01 Epub Date: 2025-11-21 DOI: 10.1016/j.cliser.2025.100628

There has been an increase in interest in weather and climate information services (WCIS) in the agriculture sector, but pastoralism (extensive rearing of livestock) has received less attention than crop agriculture. This paper presents a scoping review of literature to assess what is known on WCIS for pastoralists from Web of Science, Google Scholar and selected organisations working in these fields. The review generated 51 papers published between 2000 and 2024 covering multiple regions, but with 80% focusing on Africa. Papers address various aspects of WCIS, with particular focus on users. Themes for which there are evidence include the role of indigenous and scientific forecasting, identifying user needs, how to generate and communicate information in such a way as to encourage use, risk perceptions and use of WCIS, including the benefits. The evidence base is small but growing, and there is some commonality of themes with other fields. Challenges persist in how to generate and effectively communicate salient, credible and legitimate information. The particularly strong focus on indigenous and scientific forecasts highlights the importance of indigenous knowledge to many pastoralist communities and raises questions about how best to integrate knowledge types. Future research directions in pastoralist WCIS, like in other fields, are likely to cover issues such as evaluation and sustainability, and also how WCIS can support other adaptation and risk reduction efforts.
农业部门对天气和气候信息服务(WCIS)的兴趣有所增加,但与作物农业相比,畜牧业(广泛饲养牲畜)受到的关注较少。本文对来自Web of Science、b谷歌Scholar和在这些领域工作的选定组织的文献进行了范围审查,以评估牧民WCIS的已知情况。该综述在2000年至2024年期间发表了51篇论文,涵盖多个地区,但其中80%集中在非洲。论文讨论了WCIS的各个方面,特别关注用户。有证据支持的主题包括:本地和科学预测的作用、确定用户需求、如何以鼓励使用的方式产生和传播信息、风险认知和使用世界信息中心,包括其益处。证据基础虽小但在不断增长,并且与其他领域的主题有一些共性。如何产生和有效地传播突出的、可信的和合法的信息仍然是挑战。对土著和科学预测的特别重视突出了土著知识对许多牧民社区的重要性,并提出了如何最好地整合各种知识的问题。与其他领域一样,牧民WCIS未来的研究方向可能包括评估和可持续性等问题,以及WCIS如何支持其他适应和降低风险的努力。

Evaluating weather and climate information services for heat and drought adaptation in Southeast Europe: gaps, opportunities and design principles 评估东南欧适应高温和干旱的天气和气候信息服务:差距、机会和设计原则
IF 4.5 3区 环境科学与生态学 Q2 ENVIRONMENTAL SCIENCES Pub Date : 2025-12-01 Epub Date: 2025-11-05 DOI: 10.1016/j.cliser.2025.100626

Although many Weather and Climate Information Services are available in Southeast Europe, their contribution to enhancing long-term climate resilience remains unclear. This study evaluates the role of WCIS in supporting climate change adaptation in SEE with regard to extreme heat and drought events, and identifies key gaps. In this study, heat and drought refer to perceived conditions of elevated temperature and prolonged precipitation deficit as understood by stakeholders, rather strictly defined meteorological thresholds. The analysis draws on a mixed-methods approach combining bibliometric and market analysis, surveys, and semi-structured interviews, with results reflecting predominantly qualitative, perception-based insights. Findings highlight persistent challenges in WCIS user engagement, stemming from gaps in design and communication. Many services in SEE adopt top-down approaches with limited user involvement and inadequate educational support. Strengthening participation and promoting transparency in information dissemination are crucial. Tailoring WCIS to specific sectors, such as agriculture, public health, and water management, can help ensure relevance to local needs. Technical challenges remain regarding reliability, trustworthiness and performance of WCIS related to heat- and drought-related impacts. The study concludes with five key recommendations: 1) improve cross-scale engagement, 2) ensure transparency, 3) address sector-specific needs, 4) enhance user-friendliness, and 5) increase reliability and trust.
虽然东南欧有许多天气和气候信息服务,但它们对增强长期气候适应能力的贡献尚不清楚。本研究评估了WCIS在支持SEE地区对极端高温和干旱事件的气候变化适应方面的作用,并确定了关键差距。在本研究中,高温和干旱是指利益相关者所理解的温度升高和降水不足延长的感知条件,而不是严格定义的气象阈值。该分析采用了文献计量学和市场分析、调查和半结构化访谈相结合的混合方法,其结果主要反映了定性的、基于感知的见解。调查结果强调了WCIS用户参与方面的持续挑战,这些挑战源于设计和沟通方面的差距。SEE的许多服务采用自上而下的方法,用户参与有限,教育支持不足。加强参与和促进信息传播的透明度至关重要。根据农业、公共卫生和水管理等具体部门调整世界卫生信息系统,有助于确保与当地需求相适应。与高温和干旱相关的影响有关的WCIS的可靠性、可信度和性能方面的技术挑战仍然存在。该研究总结了五项关键建议:1)改善跨规模参与;2)确保透明度;3)满足特定行业需求;4)增强用户友好性;5)提高可靠性和信任度。

Crop choice advisory for the West African Sudan Savanna based on soil type and presowing rainfall forecasts: A machine learning residual model approach 基于土壤类型和播种前降雨预测的西非苏丹大草原作物选择咨询:机器学习残差模型方法
IF 4.5 3区 环境科学与生态学 Q2 ENVIRONMENTAL SCIENCES Pub Date : 2025-12-01 Epub Date: 2025-08-19 DOI: 10.1016/j.cliser.2025.100605

Crop choice is a critical decision for rainfed smallholder farmers when allocating land between food and cash crops. To inform crop choice, process-based models need to simulate yield responses that are both eco-physiologically plausible and quantitatively accurate. Achieving this is difficult when data quality and scarcity hinder model calibration. Here, we present a modification of a process model simulation performed using a machine learning residual model trained to predict the error in the process model-simulated yields, relative to field experimental data, from growing conditions. Using the random forest (RF) algorithm, residual models were developed for cowpea, groundnut, soybean, maize, millet, and sorghum cultivated at three locations in Burkina Faso. The RF residual models improved the agreement between the process model simulations and the field data while preserving plausible crop-specific rainfall–yield relationships and their variation across soil types with differing water retention or drainage capacities (i.e., Lixisols and Plinthosols). Subsequently, process model simulations for 1994–2023 were adjusted using the RF residual models. The findings showed that the better performing crops varied with respect to soil type and seasonal rainfall. However, the utility of presowing rainfall forecasts for dynamic crop choice was limited by relatively high miss rates. The proposed crop choice advisory is expected to increase the income and nutrient status of smallholder farmers in dryland regions of West Africa under rainfall variability.
在粮食作物和经济作物之间分配土地时,作物选择是雨养小农的一个关键决定。为了为作物选择提供信息,基于过程的模型需要模拟既在生态生理学上合理又在数量上准确的产量响应。当数据质量和稀缺性阻碍模型校准时,实现这一点是困难的。在这里,我们提出了一个过程模型模拟的修改,使用机器学习残差模型进行训练,以预测过程模型模拟产量的误差,相对于田间实验数据,从生长条件。利用随机森林(RF)算法,对布基纳法索三个地点种植的豇豆、花生、大豆、玉米、小米和高粱建立残差模型。RF残差模型改进了过程模型模拟与田间数据之间的一致性,同时保留了似是而非的作物特定降雨量-产量关系及其在不同保水或排水能力的土壤类型(即Lixisols和Plinthosols)之间的变化。随后,利用RF残差模型对1994-2023年的过程模型模拟进行了调整。结果表明,不同土壤类型和季节降雨对作物的影响不同。然而,播前降雨预报对动态作物选择的效用受到相对较高的失误率的限制。拟议的作物选择咨询预计将在降雨变化的情况下增加西非干旱地区小农的收入和营养状况。
