Adding the Farmer Domain to Aquifer Recharge: Insights From Smallholder Farmers' Natural Water Retention Measures in the Danube–Tisza Interfluve, Hungary

open access: yesWorld Water Policy, Volume 12, Issue 4, November 2026.
ABSTRACT This paper describes and analyzes recharge practices in Bács‐Kiskun County, Hungary, within what can be categorized as the farmer domain. Such locally embedded aquifer recharge practices remain underexplored in Hungary. Current research and funding largely focus on large‐scale Managed Aquifer Recharge (MAR) interventions emphasizing intended ...

Decarbonization and the Rescaling of Water–Energy Bargaining: How Renewable Expansion Is Reshaping Iran–Iraq–Türkiye Transboundary Water Politics

open access: yesWorld Water Policy, Volume 12, Issue 4, November 2026.
ABSTRACT This article examines how renewable‐energy expansion is changing water–energy bargaining among Iran, Iraq, and Türkiye in the Tigris–Euphrates basin. Much of the existing literature on transboundary water politics focuses on territorial control, upstream–downstream power asymmetries, legal rules, and hydro‐hegemony but gives less attention to ...

基于水资源分区和地貌特征的新疆耕地资源变化分析[J]

open access: yes, 2012
以新疆1995、2000、2005及2008年4个时期的土地利用数据为基础,结合水资源分区、SRTM-DEM和数字地貌等数据,分析了基于水资源分区和地貌特征的新疆耕地资源的变化特征,结果表明:①总体上,不同时段各水资源分区耕地空间分布稍有变化,但总体格局保持不变。不同时段各水资源分区的耕地面积有增有减,但增加量远超过减少量,耕地总体呈现出持续增长的趋势,从1995年到2008年,共增加126.39×104hm2。②对比4个时期26个水资源分区的耕地数值、变化和升降形式差异,可将耕地变化形式归纳为上升 ...

油田含聚丙烯酰胺污水生物转化及能源化与资源化

open access: yesGongye shui chuli, 2023
目前油田面临含水解聚丙烯酰胺(HPAM)污染物亟待处置的现状,低成本、环境友好型的生物降解转化技术已成为处理典型有机污染物HPAM的主力技术。生物处理系统不仅是污染物衰减的终端,而且是污染物向生物能源和资源转化的关键场所。近年来,生物法处置含HPAM污水的发展趋势正从“提高去除效能-挖掘降解机制”逐渐过渡到“回收能量-增值资源-净化环境”三位一体的新方向。因此,围绕石油开发过程中产生的典型有机污染物HPAM,以国家对资源和能源的需求为契机,重点综述了HPAM生物降解菌群、转化途径、动力学与热力学 ...

From the Margins: Potential Coalitions in Centralized, High‐Capacity States

open access: yesPolicy Studies Journal, Volume 54, Issue 4, November 2026.
ABSTRACT The early stages of coalition formation remain an understudied area, particularly in centralized, high‐capacity political systems. Examining actor dynamics at this formative stage can reveal how coalitions form and how limited pluralism constrains their development.

民族文化旅游资源评价与开发主题分析--以哈萨克民族文化旅游资源为例[C]

open access: yes, 2011
旅游资源评价是在一定尺度的时空范围内对资源数量、资源丰度、资源级别构成、类型、空间组合情况以及外部环境的综合评价。其意义在于科学评价旅游资源开发利用的现状、客观分析其发展变化规律,从而为旅游资源开发与保护以及区域旅游业发展提供科学决策依据。本文综合分析了哈萨克民族的文化特征、地理分布和区域分工等因素,对哈萨克民族文化旅游资源进行了系统分类和总结,采取定性与定量相结合的方法构建了民族文化旅游资源评价指标体系。从观赏性、历史文化价值、科学价值、艺术价值、奇特度、规模丰度、完整性等因子和旅游资源的组合度 ...

Competitive Anion Coordination Modulates Anode Interfacial Chemistry for Wide‐Temperature Sodium Batteries

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Sodium‐ion batteries (SIBs) offer a promising, cost‐effective alternative for large‐scale energy storage due to the abundance of sodium. However, their practical deployment is challenged by sluggish interfacial kinetics and unstable interphase formation, which severely limit performance across wide temperature ranges. Here, we demonstrate that
