World Water Policy, Volume 12, Issue 3, August 2026.ABSTRACT Village tank cascade systems (VTCS) are a long‐established form of water management in Sri Lanka's dry zone. However, their role in groundwater recharge, climate adaptation, and water governance remains insufficiently recognized in policy and planning.

World Water Policy, Volume 12, Issue 3, August 2026.ABSTRACT Bengaluru, a primary metropolitan centre in India, is currently grappling with the dual crises of urban flooding and severe groundwater depletion. These challenges are driven by rapid urbanization, which has seen built‐up areas increase from 42% to 86% over two decades, resulting in a dramatic loss of vegetation and wetlands.

Shuitu Baochi Xuebao, 2002 黄土高原生态脆弱，沟壑纵横，水土流失非常严重，究其原因主要是长期以来人们破坏植被的结果。西部大开发，水土保持特别是生态环境建设要先行，而水土保持又离不开植被建设。长期以来，人们已经认识到植被的重要性，但是关于植被在水土保持中的地位和作用，人们尚不太明确。为此，探讨了植被破坏对水土流失、生态环境的危害以及植被的各部分在保持水土方面的功效，认为植被措施具有极强的生态效益和社会效益，在水土保持中的地位是无可替代的，是水土保持的根本性措施。

Shuitu Baochi Xuebao, 2021 为了研究中国西南水梯田的土壤水分特性，以云南哈尼梯田为例，选取哈尼梯田核心区全福庄小流域内林地、荒草地、旱地和水田4种土地利用类型，分层取0—10，10—20，20—40，40—60，60—80，80—100 cm深度土样测其主要土壤理化指标和土壤水分特征曲线，分析其土壤的持水性和水分有效性。结果表明：（1）哈尼梯田4种不同土地利用类型土壤容重变化范围为0.61~1.41 g/cm3，且0—40 cm与40—100 cm差异性显著，土壤有机质含量为1.17%~9.65 ...

World Water Policy, Volume 12, Issue 3, August 2026.ABSTRACT In Ghana, the government has initiated a reform in rural water management to shift away from community‐based management (CBM) to state management, but research assessing the reform is still insufficient. This study aims to critically evaluate the impact of the reform in addressing rural water challenges.

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).

Shuitu Baochi Xuebao, 2019 以福建省西部宁化县紫色土区梯田+杨梅+百喜草（C1）、山边沟+鱼鳞坑+金银花（C2）、隔坡梯田+鱼鳞坑+油茶（C3）、鱼鳞坑+油茶（C4）、竹节沟+乔灌草（C5）5种水土保持措施和无水土保持措施（CK）的紫色土坡地为研究对象，对比分析不同水土保持措施下闽西紫色土速效养分含量及可蚀性特征差异，并揭示土壤速效养分与可蚀性特征间的相互关系。结果表明：5种水土保持措施下紫色土速效养分含量除硝态氮外均高于CK，其中，铵态氮（NH4+-N）、硝态氮（NO3--N）、速效磷（AP）、速效钾（AK）含量分别呈现C2 >

Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Although significant biodiversity has been safeguarded by protected areas (PAs), biodiversity trends continue downward. Within the frameworks of the EU Biodiversity Strategy for 2030 and the new EU Restoration Regulation (2024), conserving critical biodiversity areas is essential.

Shuitu Baochi Xuebao, 2008 对3种引进草种的生物量、枯落物量、土壤的容重、孔隙度、自然含水量、毛管持水量、饱和含水量、机械组成、有机质含量、渗透性能和抗蚀能力等进行了测定和分析。结果表明,3种引进草种的水土保持效果依次为纳罗克非洲狗尾草>威提特东非狼尾草>沙弗雷肯尼亚白三叶草,纳罗克非洲狗尾草的持水能力和土壤改良性能最好,是水土保持效果最佳的牧草,可以推广种植,其次是威提特东非狼尾草。
