The Limits of Depoliticized Water–Energy Diplomacy: Insights From the UAE–Israel–Jordan Water‐for‐Energy Deal

open access: yesWorld Water Policy, Volume 12, Issue 1, February 2026.
ABSTRACT This paper examines the rise and collapse of the 2021 United Arab Emirates (UAE)–Israel–Jordan Water‐for‐Energy Deal, a landmark initiative that sought to exchange Jordanian solar energy for Israeli desalinated water. Presented as a breakthrough in regional cooperation and environmental peacebuilding, the agreement was brokered under the ...

黄河中游昕水河流域水沙变化及归因研究

open access: yesShuitu Baochi Xuebao, 2021
为了探讨人类活动和气候变化对黄河流域水沙情势的影响,选取黄河中游典型流域——昕水河流域为研究区域,分析流域1958—2015年水文气象年际变化规律,采用Mann-Kendall检验法和Pettitt检验法对流域径流量、输沙量及含沙量进行趋势分析和突变检验,并分别利用双累积曲线法、回归分析法和弹性系数法对水沙变化的归因进行了对比评价。结果表明:(1)流域多年平均径流量、输沙量和含沙量分别为32.0 mm,1 289.1 t/km2和33.7 kg/m3,年径流量、输沙量和含沙量均呈现显著下降趋势 ...

Long-Term Trends of Macrobenthos in Southern Bohai Sea, China, in Relation toEnvironmental Changes [PDF]

open access: yes, 2016
根据50多年来渤海南部海域大型底栖动物群落的历史资料,以及2011~2013年的现场调查数据,从渤海南部包括黄河口邻近海域及莱州湾大型底栖动物群落结构变化特征出发,分析了其长期演变的过程和规律,旨在阐明底栖动物群落的演变趋势,识别其重要的演变时段.并结合50年来渤海南部海域相关底栖环境因子的变化特征,探讨底栖动物群落的演变原因.过去50余年来,渤海南部海域大型底栖动物群落在物种数、生物量、丰度以及群落结构组成等方面都发生了较大的变动,具体表现为寿命长、体积大、具有高竞争力的K对策种的优势地位正逐渐丧失 ...

Assessing the Corn Belt as an anthropogenic barrier to migrating landbirds in the United States

open access: yesConservation Biology, Volume 39, Issue 5, October 2025.
Abstract Migrating landbirds adjust their flight and stopover behaviors to efficiently cross inhospitable geographies, such as the Gulf of Mexico and the Sahara Desert. In addition to these natural barriers, birds may increasingly encounter anthropogenic barriers created by large‐scale changes in land use. One such barrier could be the Corn Belt in the

On the normative roles of biodiversity and naturalness in conservation

open access: yesConservation Biology, Volume 39, Issue 5, October 2025.
Abstract Nature is an opaque concept. Consequently, the term biodiversity conservation has replaced nature conservation in most conservation contexts. We review the conceptual indeterminacies that plague the terms nature and natural but then show that comparable difficulties plague biodiversity.

Reoccurrence of Dust Storms in South Asia and Their Implications for Vegetation Health 南亚沙尘暴的再次出现及其对植被健康的影响

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 362-380, September 2025.
Occurrences of dust storms and long‐distance movement of dust across landscapes is constantly increasing in south Asia. This dust is expected to have profound impact on vegetation health and sustainability as dust may contribute to nutrient budgets of the forest ecosystems, while it could impart various stresses to the plants.

Prospects for conserving freshwater fish biodiversity in the Anthropocene: A view from Southern China 人类世下淡水鱼类生物多样性保护的前景:以中国南方为视角

open access: yesIntegrative Conservation, Volume 3, Issue 4, Page 294-311, December 2024.
Freshwater biodiversity in China is threatened by multiple anthropogenic factors, and while there are some reasons to suppose it may be possible to bend the curve of biodiversity loss, the variety of threats and their likely interactions with ongoing climate change provide little basis for optimism. For example, the historic overexploitation of Yangtze

降雨量和水土保持对皇甫川输沙量变化的贡献率分析

open access: yesShuitu Baochi Xuebao, 2023
为探究黄河支流输沙量减少与流域内降雨量变化及水土保持措施的定量关系。以黄河中游皇甫川流域为研究区域,基于1960—2015年准格尔气象站日降水量、皇甫水文站年径流量和年输沙量数据,分析对皇甫川流域年径流量与年输沙量有影响的降雨量参数。通过双累积曲线法和突变点检验法确定输沙量变化的3个典型时期:Per1(1960—1986年)、Per2(1987—1999年)和Per3(2000—2015年);计算了降雨量变化、植被恢复和工程措施对该流域不同时期输沙量变化的贡献率。结果表明:(1)1960 ...

近70年长江干流寸滩站以上流域水沙关系

open access: yesShuitu Baochi Xuebao, 2021
以长江干流寸滩水文站以上流域为研究对象,基于1953-2018年的实测水沙资料,采用线性回归、Mann-Kendall趋势检验和水沙关系曲线分析径流、输沙的时间趋势及其关系变化,并采用双累积曲线法分析水沙变化的驱动因素。结果表明:寸滩站以上流域多年平均径流量为3 425亿m3,多年平均输沙量为3.61亿t;多年平均月径流量为294.8亿m3,多年平均月输沙量为3 013万t,且主要分布在6-10月,分别占年径流泥沙总量的70%和95%以上。趋势分析显示,流域年降雨量和径流量变化趋势不明显 ...
