Flood information systems: Needs and improvements in Eastern India

Flood warning systems offer a large potential for reducing human losses and property damage in flood-prone regions. This article illustrates why official organized systems should not be relied on completely in either developing or developed societies. It then discusses an indigenous flood warning system in a rural area of Eastern India, its value, and its importance in providing an alternative means of detecting, interpreting, and relaying flood warning information to the ultimate users of this information, i.e., those populations most at risk from floods.The National Center for Atmospheric Research is operated by the University Corporation for Atmospheric Research and is sponsored by the National Science Foundation.     

节水知识、意识和行为的现状评估及系统分析——以北京市中学生为例

节约用水是缓解水资源紧缺的有效途径,涉及社会心理层面认知、意愿的复杂状态。设计问卷对312名北京市中学生的节水知识、意识和行为进行现状评估,系统分析三者相互关系,为推行更为有效的节水管理措施提供支持。结果显示,节水知识、意识和行为问卷的信度指标(Cronbach’sα)值分别为0.82、0.77和0.84。中学生群体缺乏对节水的精确定量认知,难以判别用水的合理程度;电视是当前的主要知识来源。水资源的稀缺性被广泛认同,中学生群体具有一定的敏感度和节水责任感,能够感知水资源条件的变化;但缺乏深入理解,尤其存在"口号化"的倾向。中学生群体在节水行为方面有待改进。通过改变自身用水方式达到节水目的的行为发生频次超过半数,而改变他人用水方式的人际行为发生率较低。节水意识显著影响节水行为,节水知识对节水意识的影响不具统计意义。节水知识除直接影响节水行为外,还通过节水意识的中介效应影响节水行为,两者效果比例大约9∶1。

Trees as brokers in social networks: Cascades of rights and benefits from a Cultural Keystone Species

Indigenous trees play key roles in West African landscapes, such as the néré tree (Parkia biglobosa (Jacq.) R.Br. ex G.Don). We applied social–ecological network analysis to understand the social–ecological interactions around néré. We documented the benefits néré provides and the multiple social interactions it creates amongst a large range of actors. The flows of rights over the trees and benefits from them formed two hierarchical networks, or cascades, with different actors at the top. The two forms of power revealed by the two cascades of rights and benefits suggest possible powers and counter-powers across gender, ethnicity, and age. We documented how the tree catalyses social interactions across diverse groups to sustain vital social connections, and co-constitute places, culture, and relationships. We argue that a paradigm shift is urgently needed to leverage the remarkable untapped potential of indigenous trees and Cultural Keystone Species in current global restoration and climate change agendas.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13280-022-01733-z.     

基于CiteSpace的国内外人工湿地研究动态与未来展望

人工湿地因具有耗资少、处理效果好等优点受到国内外学者的高度关注,相关研究文献数量大幅增长,但有关人工湿地领域的文献分析相对缺乏。基于文献计量学的方法,以中国知网（CNKI）核心期刊数据库和Web of Science（WoS）核心合集数据库为数据源,利用CiteSpace等软件对2000—2021年人工湿地领域国内外发表的文献进行统计分析;基于年发文量、发文国家、发文作者、研究方向和研究热点演化等的对比分析,揭示国内外研究动态差异。结果表明：2000—2021年,国内外关于人工湿地研究的年发文量呈快速上升趋势;在WoS核心合集数据库中,中国学者发文量居世界首位。国外人工湿地领域的主要研究方向,在传统研究的基础上还关注到了耦合微生物燃料电池技术与个人护理品等新兴污染物的去除等;国内人工湿地领域的主要研究方向围绕除污机理、除污效能、除污对象及其应用4方面展开。利用基因测序技术从微观角度研究人工湿地和人工湿地-微生物燃料电池耦合技术将是近年人工湿地领域的研究热点。人工湿地技术已进入成熟阶段,未来有望与更多新兴领域结合。

     

The relationship between demographic/educational parameters and perceptions,knowledge and earthquake mitigation in Israel

Perceptions, knowledge and mitigation are factors that might play a role in preventing injury and loss of life during a major earthquake.² Little is known about the relationships between different demographic and educational parameters and these factors. A national representative sample of 495 adults was investigated in order to determine the relationship between demographic and educational parameters in terms of the perceived threat, perceived coping, knowledge and mitigation of earthquakes in Israel. Compared to females, males perceived the threat of earthquakes to be lower (t=3.183, p=0.002), manifested higher levels of perceived coping (t=2.55, p=0.011), and had higher levels of earthquake related knowledge (t=2.047, p=0.041). We conclude that there are gender differences in perceptions and knowledge regarding earthquakes.     

A mixed methodology for evaluating use of evidence in conservation planning

Conservation practitioners widely recognize the importance of making decisions based on the best available evidence. However, the effectiveness of evidence use in conservation planning is rarely assessed, which limits opportunities to improve evidence-based practice. We devised a mixed methodology for empirically evaluating use of evidence that applies social science tools to systematically appraise what kinds of evidence are used in conservation planning, to what effect, and under what limitations. We applied our approach in a case study of the Nature Conservancy of Canada (NCC), a leading land conservation organization. We conducted qualitative and quantitative analyses of 65 NCC planning documents (n = 13 in-depth) to identify patterns in evidence use, and surveyed 35 conservation planners to examine experiences of and barriers to using evidence. Although claims in plans contained a wide range of evidence types, 26% of claims were not referenced or associated with an identifiable source. Lack of evidence use was particularly apparent in claims associated with direct threats, particularly those identified as low (71% coded as insufficient or lacking evidence) or medium (45%) threats. Survey participants described relying heavily on practitioner experience and highlighted capacity limitations and disciplinary gaps in expertise among planning teams as barriers to using evidence effectively. We found that although time-intensive, this approach yielded actionable recommendations for improving evidence use in NCC conservation plans. Similar mixed-method assessments may streamline the process by including interviews and refining the document analysis frames to target issues or sections of concern. We suggest our method provides an accessible and robust point of departure for conservation practitioners to evaluate whether the use of conservation planning reflects in-house standards and more broadly recognized best practices.     

The Boiling Liquid Expanding Vapour Explosion (BLEVE): A bibliometric review and futur trends

The phenomenon “Boiling Liquid Expanding Vapor Explosion” (BLEVE) is one of the most common accidental events in the chemical industry and in the transport of dangerous goods. A bibliographic search in the Web of Science Core Collection reported 375 publications related to BLEVEs from 1979 to the present (August 10, 2022). A bibliometric analysis was conducted using the VOSviewer tool to allow a better understanding of the scientific knowledge on this phenomenon. A comprehensive overview of BLEVE research is presented in terms of annual publication, top journals, countries/regions with the highest productivity, authors and their cooperation networks, key terms, and co-citation analysis. The 375 publications cover 691 authors, 83 journals, 44 countries or territories and 290 institutions. The key publication (highest number of citations and co-citations) for understanding the BLEVE phenomenon is. The results obtained constitute a snapshot of the current state of the art on BLEVEs and can be applied to improve the understanding of research on this topic and establish new trends of research.     

Socioeconomic development and ecological traits as predictors of human–bird conflicts

Because of the significant impacts on both human interests and bird conservation, it is imperative to identify patterns and anticipate drivers of human–bird conflicts (HBCs) worldwide. Through a global systematic review, following the PRISMA 2020 guidelines, we analyzed the socioeconomic factors and bird ecological traits driving the degree of knowledge and extent of HBCs. We included 166 articles published from 1971 to 2020 in our analyses through which we built a profile of the socioeconomic conditions of 52 countries with reported conflicts and the ecological traits of the 161 bird species involved in HBCs. Although HBC expanded worldwide, it had the greatest impact in less-developed countries (estimate 0. 66 [SE 0.13], p< 0.05), where agriculture is critical for rural livelihoods. Species with a relatively greater conflict extent had a relatively broader diet (estimate 0.80 [SE 0.22], p<0.05) and an increasing population trend (estimate 0.58 [SE 0.15], p<0.05) and affected human interests, such as agriculture and livestock raising. In countries with greater biodiversity, HBCs caused greater socioeconomic impacts than in more developed countries. Our results highlight the importance of understanding and addressing HBCs from multiple perspectives (ecological, sociocultural, and political) to effectively protect both biodiversity and local livelihoods.
