Agroforestry is crucial for improving water quality deteriorated by anthropogenic activities due to the use of chemical substances, including nitrogen (N) and phosphorous (P) in modern agricultural practices (MAPs). This state-of-the-art review aims to revise the influence of agroforestry systems (AFS) on climate change, soil conservation, and groundwater quality. The novelty of this review is that AFS can improve water quality, reduce nutrient loss, and support the biological, chemical, and physical properties of the soil. It is worth noting that the surficial geologic controls, slope gradient, soil types, and topographical conditions are factors that alter a watershed dominated by agroforestry areas. In addition, anthropic aspects, including agricultural practices, can also cause loss of water quality in basins dominated by an AFS area. This review is also novel in that it outlines how AFS can be used for the phytoremediation of contaminated soils to reduce aluminum (Al), mercury (Hg), and cadmium (Cd), among others. Therefore, AFS can be used for water decontamination, climate change mitigation, climate adaptation, and soil conservation. Further research is required to investigate the contribution of AFS to soil integrity.
农林复合经营对于改善因现代农业实践中使用包括氮和磷在内的化学物质而导致的人为活动而恶化的水质至关重要。这篇最新综述旨在修正农林系统(AFS)对气候变化、土壤保持和地下水质量的影响。这篇综述的新颖之处在于,AFS可以改善水质,减少养分损失,并支持土壤的生物、化学和物理特性。值得注意的是,地表地质控制、坡度、土壤类型和地形条件是改变以农林区为主的流域的因素。此外,包括农业实践在内的人为因素也可能导致AFS地区主导的流域水质损失。这篇综述也很新颖,因为它概述了AFS如何用于污染土壤的植物修复,以减少铝(Al)、汞(Hg)和镉(Cd)等。因此,AFS可用于水净化、减缓气候变化、适应气候和土壤保护。需要进一步研究AFS对土壤完整性的贡献。

The poor conditions of rivers worldwide make restoration an issue of great importance and urgency. The acceptance of restoration by society is crucial, however, the factors determining such acceptance are still poorly understood. In particular, the understanding of the complex interplay between the acceptance or rejection of specific project components and the acceptance of the overall project require further exploration. To address this research gap, we analyze a restoration project in Bad Bergzabern, Germany to (1) investigate the acceptance of the overall project and its components, and (2) explore why people accept or reject specific components. Three hundred and twenty-one in-person interviews were conducted and the factors of acceptance were analyzed using logistic regression. Our findings show that while acceptance of the overall project is generally high, many respondents reject one or more project components. Complementary social project components, like a playground, find less support than purely ecological components. Overall, our research shows that differences in the acceptance of components depend on individual concerns, the quality of communication, attachment to the site, and age. Our results contribute to a better understanding of preferences for river restoration projects and help water managers design restoration projects that are highly accepted by society.
世界各地河流的恶劣条件使修复成为一个非常重要和紧迫的问题。社会对修复的接受是至关重要的,然而,对决定这种接受的因素仍知之甚少。特别是,要理解接受或拒绝特定项目组成部分与接受整个项目之间的复杂相互作用,还需要进一步探索。为了弥补这一研究空白,我们分析了德国巴特伯格扎本的一个修复项目,以(1)调查整个项目及其组成部分的接受程度,以及(2)探讨人们为什么接受或拒绝特定的组成部分。进行了321次面对面访谈,并使用逻辑回归分析了接受的因素。我们的调查结果表明,虽然总体项目的接受度普遍较高,但许多受访者拒绝接受一个或多个项目组成部分。互补的社会项目组成部分,如游乐场,比纯粹的生态组成部分得到的支持更少。总体而言,我们的研究表明,组件接受度的差异取决于个人关注点、沟通质量、对网站的依恋程度和年龄。我们的研究结果有助于更好地了解人们对河流修复项目的偏好,并帮助水资源管理者设计出被社会高度接受的修复项目。

Considering that the current water crisis is largely a governance crisis, improving water governance will help address current and future water challenges. Water governance is defined as the range of political, institutional and administrative rules, practices and processes through which decisions are taken and implemented, stakeholders can articulate their interests and have their concerns considered, and decision-makers are held accountable for water management. The Water Governance Principles proposed by the OECD contribute to the creation of tangible public policies oriented towards effectiveness, efficiency, reliability and participation. The aim of this research is to apply the OECD Water Governance Indicator Framework at a local level and to identify gaps and challenges for water governance in the General Pueyrredon Municipality (GPM), Buenos Aires Province (BAP), Argentina. This framework was used as a diagnostic tool to assess water governance policy frameworks (what), institutions (who) and instruments (how). In general terms, there is a robust legal framework, there are enforcement institutions regarding water management and there is a good connection with them. However, the main challenges identified were in the ‘how’ since most of the instruments are partly or not implemented.
考虑到当前的水危机在很大程度上是一场治理危机,改善水治理将有助于应对当前和未来的水挑战。水治理被定义为一系列政治、体制和行政规则、做法和流程,通过这些规则、做法、流程做出和实施决策,利益相关者可以阐明自己的利益并考虑自己的关切,决策者对水管理负责。经合组织提出的水治理原则有助于制定切实可行的公共政策,以实现有效性、效率、可靠性和参与性。本研究的目的是在地方一级应用经合组织水治理指标框架,并确定阿根廷布宜诺斯艾利斯省普埃雷登市水治理的差距和挑战。该框架被用作评估水治理政策框架(什么)、机构(谁)和工具(如何)的诊断工具。总的来说,有一个健全的法律框架,有关于水管理的执法机构,并且与它们有着良好的联系。然而,确定的主要挑战在于“如何”,因为大多数文书都得到了部分实施或没有实施。

The Punjab Public Health Engineering Department (PHED) and community-based organizations (CBOs) collaboratively manage the rural water supply (RWS) system in Punjab, Pakistan since the mid-nineties. In a command-and-control administration, a collaborative approach to managing RWS is peculiar. The study addresses this gap by analyzing the relational behavior as a monitoring and enforcement mechanism to ensure community compliance with government-produced institutions for managing RWS. Four focus group interviews were conducted with the CBO members and the survey of households from the same villages. Using the partial-least square structural equation model (PLS-SEM), the mediating influence of frequent communication, commitment of users, and shared meaning on community compliance with institutions was analyzed. The integrated results from the two methods imply that trained CBOs better self-organize, as they communicate frequently with the community members. It is recommended that for the sustainability of the RWS system, regular government support for CBOs underscores the success of collaborative collective action, though trained CBOs better manage RWS in weak monitoring by the government.
自90年代中期以来,旁遮普省公共卫生工程部(PHED)和社区组织(CBO)合作管理巴基斯坦旁遮普省的农村供水系统。在指挥控制管理中,管理RWS的协作方法是独特的。该研究通过分析关系行为作为一种监测和执行机制来解决这一差距,以确保社区遵守政府制定的RWS管理机构。对国会预算办公室成员进行了四次焦点小组访谈,并对来自同一村庄的家庭进行了调查。利用偏最小二乘结构方程模型(PLS-SEM),分析了频繁沟通、用户承诺和共享意义对社区遵守制度的中介影响。这两种方法的综合结果表明,经过培训的社区组织能够更好地自我组织,因为他们经常与社区成员交流。建议为了RWS系统的可持续性,政府对CBO的定期支持强调了合作集体行动的成功,尽管受过培训的CBO在政府监督不力的情况下更好地管理RWS。

Studying the apportionment and sharing of agricultural water prices is necessary for clarifying the relationship between agricultural water price apportionment and government responsibility and ensuring the benign operation of irrigated areas. From the perspective of the versatility of irrigation water, irrigation benefits are classified as internal or external; the degree of benefit is measured using the proportion of irrigation water per cubic metre of internal and external benefits. This is used as an allocation coefficient to reasonably share prices based on farmers’ water price tolerance, build agricultural water price apportionment and sharing models, and calculate the range of water prices borne by farmers and the government in the Baojixia Irrigation District in the Shaanxi Province of China. Results showed that the apportionment coefficients of farmers and government were 0.85 and 0.15, respectively. For grain crops, the farmers' price range was 0.115–0.508 yuan/m3, while that of the government was 0.516–0.909 yuan/m3; for cash crops, these values were 0.566–3.009 and 0.154–0.458 yuan/m3, respectively. The results of this study support the formulation of agricultural water prices and provide a theoretical reference for reducing the water burden of farmers and promoting the high-quality development of the regional economy
研究农业水价分摊与分担,对于厘清农业水价分摊与政府责任的关系,确保灌区的良性运行是必要的。从灌溉用水的通用性来看,灌溉效益分为内部效益和外部效益;效益程度是用每立方米内部效益和外部效益的灌溉水量比例来衡量的。将其作为基于农民水价承受能力的合理分担价格的分配系数,构建农业水价分摊分担模型,计算陕西省宝鸡峡灌区农民和政府承担水价的范围。结果表明,农户和政府的分配系数分别为0.85和0.15。粮食作物农民价格区间为0.115 ~ 0.508元/m3,政府价格区间为0.516 ~ 0.909元/m3;经济作物分别为0.566 ~ 3.009元/m3和0.154 ~ 0.458元/m3。研究结果支持农业水价的制定,为减轻农民用水负担、促进区域经济高质量发展提供理论参考

Evapotranspiration is one of the hot issues of ecological hydrology. However, few studies have analysed the impact of vegetation changes on water consumption from the perspective of natural and artificial vegetation to scientifically propose that there is a moderate threshold in vegetation restoration. Taking the Ziya River Basin as an example, the daily meteorological data of 11 meteorological stations from 2001 to 2015 were used to calculate the water consumption of vegetation based on the Penman–Monteith model. The results showed that from 2001 to 2015, the vegetation coverage increased. The total water consumption increased from 2001 (2.60 × 1,010 m3) to 2005 (2.65 × 1,010 m3) and decreased from 2005 (2.65 × 1,010 m3) to 2015 (2.40 × 1,010 m3). The water consumption per unit area in descending order was mixed forests (660 mm, annual average), croplands (640 mm), closed shrublands (581 mm), deciduous broadleaf forests (528 mm), grasslands (514 mm), savannas (459 mm), and woody savannas (454 mm). Finally, the regression equation between vegetation coverage change and water consumption was y = 0.377x + 84.516, which showed that there was a proportional relationship. Therefore, attention should be given to balancing local water allocation during vegetation restoration. The results can provide a reference for vegetation restoration policies
蒸发蒸腾是生态水文学研究的热点问题之一。然而,很少有研究从自然植被和人工植被的角度分析植被变化对耗水量的影响,科学地提出植被恢复存在适度阈值。以紫牙河流域为例,利用2001~2015年11个气象站的逐日气象数据,基于Penman–Monteith模型计算植被耗水量。结果表明,从2001年到2015年,植被覆盖率有所增加。总用水量从2001年(2.60×1010m3)增加到2005年(2.65×1010m3。单位面积耗水量按降序依次为混交林(660毫米,年平均值)、农田(640毫米)、封闭灌木林(581毫米)、落叶阔叶林(528毫米),草原(514毫米)和稀树草原(459毫米)以及木本稀树草原。最后,植被覆盖率变化与耗水量之间的回归方程为y=0.377x+84.516,表明存在比例关系。因此,在植被恢复过程中应注意平衡当地的水量分配。研究结果可为植被恢复政策提供参考

Freshwater resources remain under constant pressure due to population growth, economic development, and changing weather patterns. Water supply utilities generally struggle to keep up with the growing demand for freshwater resources and consequently adopt demand management policies to address supply challenges. As water consumers, households can play a major role in water conservation. This paper examines the impact of biographic characteristics on water consumption behaviour and the adoption of water-efficient technologies in the city of Durban, South Africa. Probit regression models are estimated using survey data collected from 300 household heads sampled across the city. Among other results, the study finds income as the most consistent determinant of water consumption behaviours and the adoption of water-efficient technologies. Furthermore, the level of education was also found to be a consistent determinant of the adoption and installation of water-efficient technologies. These results are significant and serve to guide water utilities when implementing demand management water policies.
由于人口增长、经济发展和天气模式的变化,淡水资源仍然面临持续的压力。供水公用事业公司通常难以跟上日益增长的淡水资源需求,因此采取了需求管理政策来应对供应挑战。作为用水者,家庭可以在节水方面发挥重要作用。本文研究了传记特征对南非德班市用水行为和节水技术采用的影响。Probit回归模型是使用从全市300名户主中收集的调查数据进行估计的。除其他结果外,该研究发现,收入是用水行为和采用节水技术的最一致决定因素。此外,教育水平也是采用和安装节水技术的一贯决定因素。这些结果意义重大,有助于指导水务公司实施需求管理用水政策。

Water pricing is the key to maximize the economic and social benefits of the water transfer project. In this study, we propose the extended linear expenditure system-water price tolerance index (ELES-WPTI) model that combines the ELES model and the WPTI method for water pricing, Firstly, the ELES model is used to estimate the price elasticity of water demand and the basic demand for farmers of different income levels. Secondly, the WPTI method is used to simulate and analyze the affordability of farmers of different income levels for agricultural water under the dynamic change of water price standards. Finally, the ELES-WPTI model is applied to the Yinda-Jihuang (YJ) Project, China, to determine the appropriate agricultural water price. The results reveal that the farmers in the DH district have is slightly higher affordability for water price than that in HL District. As water consumption should account for less than 15% of the total production cost and 10% of the net income, the affordable water price is determined to be 237 $/hm² in the DH district and 205 $/hm² in the HL district, respectively.
水价是实现调水工程经济效益和社会效益最大化的关键。在本研究中,我们提出了将ELES模型和WPTI方法相结合的扩展线性支出系统水价容忍指数(ELES-WPTI)模型。首先,利用ELES模型来估计不同收入水平农民的用水需求和基本需求的价格弹性。其次,利用WPTI方法模拟分析了水价标准动态变化下不同收入水平农民对农业用水的承受能力。最后,将ELES-WPTI模型应用于银达吉黄(YJ)项目,确定了适宜的农业水价。结果表明,DH区农民的水价承受能力略高于HL区。由于用水量应不到总生产成本的15%和净收入的10%,DH区和HL区的可负担水价分别为237$/hm²和205$/hm³。

The impact of floods on households in Uganda is becoming increasingly severe. It is often assumed that people who reside in a riverine area have adapted to flood pulses. However, in most cases, household-level risk reduction strategies are inadequate for ensuring a livelihood resilient to floods. The objective of this study was to investigate the determinants of households' decisions on coping strategies in the Manafwa catchment, Eastern Uganda. The study was based on a field survey of 210 households supplemented with focused group discussions (6) and key informant interviews (4) conducted in the Butaleja district in March 2019. The study used the protection motivation theory framework and applied the multivariate probit model. The most common short-term coping strategy was building temporary embankments (37%), whereas afforestation (44%) was the most common long-term solution deployed. The determinants that consistently and significantly influenced the choice of coping strategies adopted were: family size, number of adult males in the family, location of the house within the floodplain and time of residence in the affected area (P > 0.05). For policy purposes, this study recommends that the relevant stakeholder interventions should consider these determinants, in order to enhance the adaptive capacity of rural households to flooding.
洪水对乌干达家庭的影响越来越严重。人们通常认为居住在河边地区的人们已经适应了洪水的脉动。然而,在大多数情况下,家庭一级的减少风险战略不足以确保生计抵御洪水。本研究的目的是调查乌干达东部Manafwa流域家庭应对策略决策的决定因素。该研究基于2019年3月在Butaleja地区对210户家庭进行的实地调查,并辅以重点小组讨论和关键信息提供者访谈。本研究采用保护动机理论框架,运用多元probit模型。最常见的短期应对策略是建造临时堤防(37%),而植树造林(44%)是最常见的长期解决方案。一致且显著影响所采取应对策略选择的决定因素是:家庭规模、家庭中成年男性人数、房屋在洪泛区内的位置和在受灾地区居住的时间(P > 0.05)。从政策角度出发,本研究建议相关利益相关者干预应考虑这些决定因素,以增强农户对洪水的适应能力。
