Drought events are critical environmental threats that yield several socioeconomic impacts. Such effects are even more relevant for South America (SA) since different activities essential for the continent, such as agriculture and energy generation, depend highly on water resources. Thus, this study aimed to evaluate future changes in precipitation and hydrological drought occurrence in SA through climate projections from eight global climate models (GCMs) of CMIP6. To this end, statistical downscaling was applied to the projections obtained using the quantile delta mapping technique, and the method proved to be efficient in reducing systematic biases and preserving GCMs’ trends. For the following decades, the results show considerable and statistically significant reductions in precipitation over most of SA, especially during the austral spring, with the most intense signal under the SSP5-8.5 forcing scenario. Furthermore, GCMs showed mixed signals about projections of the frequency and intensity of drought events. Still, they indicated agreement regarding the increased duration and severity of events over the continent and a substantial proportion of moderate and severe events over most of Brazil during the 21st century. These results can be helpful for better management of water resources by decision-makers and energy planners.
干旱事件是严重的环境威胁,会产生若干社会经济影响。这种影响对南美洲更为重要,因为对该大陆至关重要的不同活动,如农业和能源生产,高度依赖水资源。因此,本研究旨在通过CMIP6的八个全球气候模式(GCMs)的气候预估来评估SA未来降水和水文干旱发生的变化。为此,将统计降尺度应用于使用分位数delta映射技术获得的投影,该方法在减少系统偏差和保留gcm趋势方面是有效的。在接下来的几十年里,结果显示南亚大部分地区的降水显著减少,特别是在南部春季,在SSP5-8.5强迫情景下信号最强烈。此外,gcm在预测干旱事件的频率和强度方面显示出不同的信号。尽管如此,他们还是一致认为,在21世纪,巴西大部分地区发生的中度和重度气候事件的持续时间和严重程度都有所增加。这些结果可以帮助决策者和能源规划者更好地管理水资源。

Climate change can have an influence on rainfall that significantly affects the magnitude frequency of floods and droughts. Therefore, the analysis of the spatiotemporal distribution, variability, and trends of rainfall over the Mahi Basin in India is an important objective of the present work. Accordingly, a serial autocorrelation, coefficient of variation, Mann–Kendall (MK) and Sen’s slope test, innovative trend analysis (ITA), and Pettitt’s test were used in the rainfall analysis. The outcomes were derived from the monthly precipitation data (1901–2012) of 14 meteorology stations in the Mahi Basin. The serial autocorrelation results showed that there is no autocorrelation in the data series. The rainfall statistics denoted that the Mahi Basin receives 94.8% of its rainfall (821 mm) in the monsoon period (June–September). The normalized accumulated departure from the mean reveals that the annual and monsoon rainfall of the Mahi Basin were below average from 1901 to 1930 and above average from 1930 to 1990, followed by a period of fluctuating conditions. Annual and monsoon rainfall variations increase in the lower catchment of the basin. The annual and monsoon rainfall trend analysis specified a significant declining tendency for four stations and an increasing tendency for 3 stations, respectively. A significant declining trend in winter rainfall was observed for 9 stations under review. Likewise, out of 14 stations, 9 stations denote a significant decrease in pre-monsoon rainfall. Nevertheless, there is no significant increasing or decreasing tendency in annual, monsoon, and post-monsoon rainfall in the Mahi Basin. The Mann–Kendall test and innovative trend analysis indicate identical tendencies of annual and seasonal rainfall on the basin scale. The annual and monsoon rainfall of the basin showed a positive shift in rainfall after 1926. The rainfall analysis confirms that despite spatiotemporal variations in rainfall, there are no significant positive or negative trends of annual and monsoon rainfall on the basin scale. It suggests that the Mahi Basin received average rainfall (867 mm) annually and in the monsoon season (821 mm) from 1901 to 2012, except for a few years of high and low rainfall. Therefore, this study is important for flood and drought management, agriculture, and water management in the Mahi Basin.
气候变化会对降雨量产生影响,从而显著影响洪水和干旱的震级和频率。因此,分析印度马希盆地降雨量的时空分布、变化和趋势是本工作的一个重要目标。因此,在降雨量分析中使用了序列自相关、变异系数、Mann–Kendall(MK)和Sen斜率检验、创新趋势分析(ITA)和Pettitt检验。结果来自马希盆地14个气象站的月降水量数据(1901–2012)。序列自相关结果表明,数据序列中不存在自相关。降雨量统计数据表明,马希盆地的降雨量占季风期(6月至9月)的94.8%(821毫米)。与平均值的归一化累积偏差表明,1901年至1930年,马希盆地的年降雨量和季风降雨量低于平均值,1930年至1990年高于平均值,随后出现了一段波动期。流域较低流域的年降雨量和季风降雨量变化增加。年降雨量和季风降雨量趋势分析表明,四个站的降雨量呈显著下降趋势,三个站的降雨呈上升趋势。所审查的9个监测站的冬季降雨量有明显下降趋势。同样,在14个测站中,有9个测站表示季前降雨量显著减少。尽管如此,马希盆地的年降雨量、季风降雨量和季风后降雨量没有显著的增加或减少趋势。Mann-Kendall检验和创新趋势分析表明,流域尺度上的年降雨量和季节降雨量趋势相同。1926年以后,该流域的年降雨量和季风降雨量出现了正变化。降雨量分析证实,尽管降雨量存在时空变化,但在流域尺度上,年降雨量和季风降雨量没有显著的正趋势或负趋势。这表明,除了几年的高降雨量和低降雨量外,马希盆地在1901年至2012年的季风季节(821毫米)每年平均降雨量(867毫米)。因此,本研究对马海流域的水旱管理、农业和水资源管理具有重要意义。

This paper presents a comprehensive review of low-carbon materials and construction techniques commonly used in vernacular buildings. The study highlights the relevance of vernacular architecture in the context of the shift towards sustainable construction practices. A combination of a climatic zone map, vernacular language type map, and continent map is used to identify the vernacular regions. Eight bio-based low-carbon materials, including wood, adobe, rammed earth, cob, sod, thatch, bamboo, and straw bales, are discussed, along with their characteristics, availability, and environmental impacts. The construction techniques associated with these materials are explained, emphasizing their simplicity, cost-effectiveness, and adaptability. The paper also explores two important design approaches: design for disassembly and design for modularity that were used in vernacular building. The review found the use of low-carbon materials and construction techniques derived from vernacular architecture can contribute to minimizing waste, reducing environmental impacts, and promoting a circular economy in the building industry. This research provides valuable insights for architects, engineers, and policymakers seeking sustainable alternatives in the construction sector.

This study analyzed long-term extreme precipitation indices using 4 × 4 km gridded data obtained from the National Meteorological Agency of Ethiopia between 1981 and 2018. The study examined trends in extreme precipitation over three districts (Lay Gayint, Tach Gayint, and Simada) in the northwestern highlands of Ethiopia. Innovative Trend Analysis (ITA) and Mann–Kendall (MK) trend tests were used to study extreme precipitation trends. Based on the ITA result, the calculated values of nine indices (90% of the analyzed indices) showed significant increasing trends (p < 0.01) in Lay Gayint. In Tach Gayint, 70% (seven indices) showed significantly increasing trends at p < 0.01. On the other hand, 60% of the extreme indices showed significant downward trends (p < 0.01) in Simada. The MK test revealed that 30% of the extreme indices had significantly increasing trends (p < 0.01) in Lay Gayint. In Tach Gayint, 30% of the extreme indices showed significant increasing trends at p < 0.05, while 10% of the extreme indices exhibited significant increasing trends at p < 0.01. In Simada, 20% of the extreme indices showed significant increasing trends at p < 0.05. Overall, the results showed that the ITA method can identify a variety of significant trends that the MK test misses.

Global and Regional Snow Cover Decline: 2000–2022 全球和区域积雪减少:2000-2002年

Snow cover affects the global surface energy balance and, with its high albedo, exerts a cooling effect on the Earth’s climate. Decreases in snow cover alter the flow of solar energy from being reflected away from Earth to being absorbed, increasing the Earth’s surface temperature. To gain a global understanding of snow cover change, in situ measurements are too few and far between, so remotely sensed data are needed. This research used the medium-resolution sensor MODIS on the Terra satellite, which has been observing global snow cover almost daily since the year 2000. Here, the MOD10C2 eight-day maximum value composite time series data from February 2000 to March 2023 were analyzed to detect global and regional trends in snow cover extent for the first 23 years of the 21st century. Trends in snow cover change during different time periods (seasons and snow-year) were examined using the Mann—Kendall test and the univariate differencing analysis. Both methods produced similar results. Globally, snow cover declined two to ten times as much as it increased, depending on the season of analysis, and annually, global snow cover decreased 5.12% (not including Antarctica or Greenland) based on the Mann—Kendall test at the 95th percentile (p < 0.05). Regionally, Asia had the greatest net area decline in snow cover, followed by Europe. Although North America has the second-largest extent of snow cover, it had the least amount of net decreasing snow cover relative to its size. South America had the greatest local decline in snow cover, decreasing 20.60% of its annual (snow-year) snow cover area. The Australia–New Zealand region, with just 0.34% of the global snow cover, was the only region to have a net increase in snow cover, increasing 3.61% of its annual snow cover area.
积雪影响全球地表能量平衡,并以其高反照率对地球气候产生冷却作用。积雪的减少改变了太阳能从地球反射到被吸收的流动,从而增加了地球表面的温度。为了获得对积雪变化的全球了解,现场测量的数据太少,因此需要遥感数据。这项研究使用了Terra卫星上的中分辨率传感器MODIS,该卫星自2000年以来几乎每天都在观测全球积雪。本文分析了2000年2月至2023年3月的MOD10C2八天最大值复合时间序列数据,以检测21世纪前23年全球和区域积雪范围的趋势。使用Mann-Kendall检验和单变量差分分析检验了不同时间段(季节和雪年)的积雪变化趋势。两种方法都产生了相似的结果。在全球范围内,根据分析季节的不同,积雪减少的幅度是增加的两到十倍。根据第95百分位的曼肯德尔测试,全球积雪每年减少5.12%(不包括南极洲或格陵兰岛)(p<0.05)。从地区来看,亚洲的积雪净面积下降幅度最大,其次是欧洲。尽管北美的积雪面积第二大,但相对于其面积而言,其净减雪量最小。南美洲的当地积雪面积下降幅度最大,减少了其年(雪年)积雪面积的20.60%。澳大利亚-新西兰地区的积雪面积仅占全球的0.34%,是唯一一个积雪面积净增加的地区,增加了其年积雪面积的3.61%。

The winter climate of the northeastern Dominican Republic features steady rainfall, which sustains cash crop production. Using a representative season, December 2016–February 2017, the mesoscale climate is characterized by high-resolution reanalysis, satellite measurements and local observations, and statistical analyses of time series from an index area of 18.8–19.6° N, 70.4–69.6° W in the Cibao Valley, where cacao and coffee are grown. Winter rainfall depends on strong trade winds that push shallow stratiform convections over 100 km inland, where nocturnal drainage flows induce orographic uplift. Interannual climate variability is studied in the context of cacao and coffee production in the years 1976–2019. Lag correlations demonstrate that higher yields follow a wet autumn, a windy winter with cool sea temperatures, and a dry spring. Changes in high-value agricultural production in the northeastern Dominican Republic may be anticipated by the climatic determinants uncovered here.
多米尼加共和国东北部的冬季气候以稳定的降雨为特征,这维持了经济作物的生产。利用代表性季节(2016年12月- 2017年2月),通过高分辨率再分析、卫星测量和当地观测,以及对可可和咖啡种植区磁宝河谷18.8-19.6°N、70.4-69.6°W指数区域的时间序列进行统计分析,对中尺度气候进行了表征。冬季降雨依赖于强烈的信风,这些信风推动内陆100公里以上的浅层对流,夜间排水流在那里引起地形隆起。以1976-2019年可可和咖啡生产为背景,研究了年际气候变率。滞后相关性表明,较高的产量发生在多雨的秋季、多风的冬季和凉爽的海水温度以及干燥的春季。这里发现的气候决定因素可以预测多米尼加共和国东北部高价值农业生产的变化。

Due to the important role of water resources in the growth of the world’s economy, drought causes global concern for its severe worldwide implications on different sectors, such as biodiversity, farming, public water supply, energy, tourism, human health, and ecosystem services. In particular, drought events can have strong environmental and socioeconomic impacts in countries depending on rain-fed agriculture such as the ones in the Mediterranean region, which, due to a detected increase in warming and precipitation decrease, is considered a climate change hotspot. In this context, in this paper, meteorological drought in the Calabria region (southern Italy) has been characterized considering the Standardized Precipitation Index (SPI) evaluated at different timescales. First, the temporal distribution of the most severe dry episodes has been evaluated. Then, a trend analysis has been conducted considering the different seasons, the wet (autumn and winter) and dry (spring and summer) periods, and the annual scale. Finally, the relationship between drought and some teleconnection patterns (the North Atlantic Oscillation—NAO, the El Niño–Southern Oscillation—ENSO, and the Mediterranean Oscillation—MO) has been investigated. Results show that the majority of the severe/extreme drought events have been observed between 1985 and 2008. Moreover, a decrease in SPI values has been observed in winter and spring, in both the wet and dry periods, and upon the annual scale considering the 12-month SPI and the 24-month SPI. Finally, a link between the drought episodes in the Calabria region and the NAO phases and the MO has been identified. Since drought episodes can severely impact water resources and their uses, the findings presented in this work can be useful to plan and manage the water supply for household, farming, and industrial uses.
由于水资源在世界经济增长中的重要作用,干旱对生物多样性、农业、公共供水、能源、旅游、人类健康和生态系统服务等不同部门的严重影响引起了全球关注。特别是,干旱事件可能会对依赖雨水灌溉农业的国家(如地中海地区)产生强烈的环境和社会经济影响,由于检测到气候变暖和降水减少,地中海地区被视为气候变化热点。在这种背景下,本文考虑到在不同时间尺度上评估的标准化降水指数(SPI),对卡拉布里亚地区(意大利南部)的气象干旱进行了表征。首先,对最严重干旱期的时间分布进行了评估。然后,考虑到不同的季节、雨季(秋冬)和旱季(春夏)以及年度规模,进行了趋势分析。最后,研究了干旱与一些遥相关模式(北大西洋涛动NAO、厄尔尼诺-南方涛动ENSO和地中海涛动MO)之间的关系。结果表明,大多数严重/极端干旱事件发生在1985年至2008年之间。此外,在冬季和春季,在雨季和旱季,以及考虑12个月SPI和24个月SPI的年度尺度上,SPI值都有所下降。最后,卡拉布里亚地区的干旱事件与NAO阶段和MO之间的联系已经确定。由于干旱会严重影响水资源及其使用,这项工作中的研究结果有助于规划和管理家庭、农业和工业用水。

As climate change has intensified flood risk and damage in many low-lying areas of the world, small and medium-sized enterprises (SMEs), which typically exist in developing countries, have endured high flood risks without much support for relief. This study investigates how SMEs in flood-prone areas of Colombo, Sri Lanka, the largest business hub in the country, have perceived and dealt with flood loss and damage in the past ten years. We conducted field surveys and a questionnaire survey among 60 SME owners in two flood-prone administrative units from March to June 2020. The results show that informal businesses experienced more flood loss and damage than other community members. Also, the community dominated by informal businesses tended to be located closer to potential flood sources. Ownership and awareness about flood insurance were very low in our study areas. Temporary business closure was the most serious loss experienced by informal business communities. These communities depended on personal savings to recover from floods. Our multiple regression analysis found that age, education, and experience significantly influenced SME owners’ perceptions and experiences about floods. After discussing these findings, this paper offers recommendations to mitigate disaster loss and damage to SMEs. In particular, it highlights the importance of community-level awareness and mitigation efforts rather than administrative unit-level mitigation plans. Also, the government needs to register informal businesses by providing a more flexible business registration mechanism.
由于气候变化加剧了世界许多低洼地区的洪水风险和破坏,通常存在于发展中国家的中小型企业在没有太多救济支持的情况下承受着高洪水风险。这项研究调查了斯里兰卡最大的商业中心科伦坡洪水多发地区的中小企业在过去十年中如何感知和应对洪水损失和破坏。2020年3月至6月,我们对两个易发洪水的行政单位的60家中小企业主进行了实地调查和问卷调查。结果表明,非正规企业比其他社区成员遭受了更多的洪水损失和破坏。此外,以非正规企业为主的社区往往位于离潜在洪水源更近的地方。在我们的研究区域,对洪水保险的所有权和意识非常低。临时企业倒闭是非正规商业社区遭受的最严重损失。这些社区依靠个人储蓄从洪水中恢复。我们的多元回归分析发现,年龄、教育程度和经验显著影响中小企业主对洪水的看法和经历。在讨论了这些发现之后,本文提出了减轻中小企业灾害损失和损害的建议。特别是,它强调了社区一级的意识和缓解工作的重要性,而不是行政单位一级的缓解计划。此外,政府需要通过提供更灵活的商业登记机制来登记非正规企业。

Climate change impacts, the resulting spatiotemporal changes, and growing uncertainty exert pressure on city leaders and policy makers to create climate adaptive development strategies worldwide. This article introduces climate urbanism as a new development paradigm that advocates for a climate adaptive urban development process, safeguarding urban economics and infrastructure, and ensuring equitable implementation of related strategies. The objective of this article is to determine how far a climate vulnerable city in the Global South has progressed toward climate urbanism. The study employs Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to develop a conceptual framework. Afterward, the analytical hierarchy process (AHP) and indexing are used to develop a multicriteria decision analysis (MCDA) method to assess the selected climate sensitive factors related to climate urbanism. Findings reveal that the city of Khulna’s climate urbanism index score is 0.36, which is extremely low and denotes subpar urban performance. ‘Climate Conscious Governance’ and ‘Climate Smart Infrastructure’ contribute little, while ‘Adaptive and Dynamic Urban Form’ and ‘Urban Ecosystem Services’ contribute even less. The binary logistic regression analysis reveals the significant indicators of (transformative) climate urbanism. The article provides a critical lens for stakeholders to evaluate climate urbanism and promote urban sustainability in the face of climate change.
气候变化的影响、由此产生的时空变化和日益增长的不确定性给城市领导人和政策制定者施加了压力,要求他们在全球范围内制定适应气候变化的发展战略。本文介绍了气候城市化作为一种新的发展范式,倡导适应气候的城市发展进程,保护城市经济和基础设施,并确保相关战略的公平实施。本文的目的是确定全球南部一个气候脆弱的城市在气候城市化方面取得了多大进展。该研究采用了系统评价和荟萃分析的首选报告项目(PRISMA)指南来制定概念框架。然后,使用层次分析法(AHP)和指数法开发了一种多准则决策分析(MCDA)方法,以评估选定的与气候城市化相关的气候敏感因素。调查结果显示,库尔纳市的气候城市化指数得分为0.36,这一分数极低,表明城市表现不佳“气候意识治理”和“气候智能基础设施”贡献甚微,而“适应性和动态城市形态”和“城市生态系统服务”贡献更少。二元逻辑回归分析揭示了(变革性)气候城市化的重要指标。这篇文章为利益相关者在气候变化面前评估气候城市化和促进城市可持续性提供了一个重要的视角。

Our aim was to investigate the association between climate anxiety and mental health in a general adult population. Cross-sectional data of the general adult population were used (n = 3091 individuals aged 18 to 74 years; March 2022). The Climate Anxiety Scale was used to assess climate anxiety. Probable depression was quantified using the PHQ-9, and the GAD-7 was used to assess probable anxiety. Adjusted for sex, age, marital status, having children in the household, highest level of school education, employment situation, smoking behavior, alcohol intake, frequency of sports activities, chronic illnesses and self-rated health and coronavirus anxiety, multiple logistic regressions showed that a higher climate anxiety was associated with a higher likelihood of probable depression (OR: 1.37, 95% CI: 1.25–1.50). Moreover, regressions showed that a higher climate anxiety was associated with a higher likelihood of probable anxiety (OR: 1.27, 95% CI: 1.15–1.40). In conclusion, our study demonstrated an association between climate anxiety and mental health in Germany. Further research (e.g., based on longitudinal data) is required to confirm our study’s findings.
我们的目的是调查气候焦虑与普通成年人群心理健康之间的关系。使用了普通成年人群的横断面数据(n=3091名18至74岁的个体;2022年3月)。气候焦虑量表用于评估气候焦虑。使用PHQ-9对可能的抑郁进行量化,并使用GAD-7评估可能的焦虑。根据性别、年龄、婚姻状况、家里有孩子、最高学校教育水平、就业状况、吸烟行为、饮酒、体育活动频率、慢性病以及自我评估的健康和冠状病毒焦虑进行调整,多元逻辑回归显示,气候焦虑越高,可能患抑郁症的可能性越高(OR:1.37,95%CI:1.25-1.50)。此外,回归显示气候焦虑越大,可能患焦虑的可能性越大(OR:1.27,95%CI+1.15-1.40)。总之,我们的研究表明,在德国,气候焦虑与心理健康之间存在关联。需要进一步的研究(例如,基于纵向数据)来证实我们的研究结果。
