Health, sanitation, and livelihoods are interrelated human rights and essential components of community wellbeing. Despite the United Nations recognizing the human right to sanitation, one-third of the world's population lack access to improved sanitation. Furthermore, in many low- and middle-income countries, urban latrines are excavated manually without physical or regulatory protections. Container-based sanitation (CBS) has promise as a component of Citywide Inclusive Sanitation (CWIS) in densely populated, low-resource environments. Before investing in CBS, however, governments and funders require evidence of user acceptance, public demand, and labor aspects of service delivery. To provide this evidence base, we completed 633 interviews with active and former users of EkoLakay, a CBS service in Cap Haïtien, Haiti, creating a profile of the user base and their motivations for subscribing. We also compiled and analyzed secondary data to determine the impacts of widespread CBS expansion in northern Haiti. Results reveal that CBS presently serves a geographical subset of Haiti's most resource-insecure residents, and that CBS significantly reduces handling of untreated excreta in Haiti's Nord Department, while doubling livelihood opportunities through safe and dignified jobs. Given its cost-effectiveness, this provides an opportunity to achieve widespread sanitation coverage by integrating and cross-subsidizing CBS within a CWIS strategy.
健康、卫生和生计是相互关联的人权,是社区福祉的重要组成部分。尽管联合国承认享有卫生设施是人权,但世界上三分之一的人口无法获得改善的卫生设施。此外,在许多低收入和中等收入国家,城市厕所是在没有物理或监管保护的情况下人工挖掘的。在人口密集、资源匮乏的环境中,基于容器的卫生(CBS)有望成为全市包容性卫生(CWIS)的一个组成部分。然而,在投资CBS之前,政府和资助者需要用户接受、公众需求和服务交付的劳动力方面的证据。为了提供这一证据基础,我们对哥伦比亚广播公司在海地Haïtien Cap提供的EkoLakay服务的活跃用户和前用户进行了633次访谈,创建了用户群及其订阅动机的档案。我们还汇编和分析了次要数据,以确定哥伦比亚广播公司在海地北部广泛扩张的影响。结果显示,哥伦比亚广播公司目前服务于海地资源最不安全的居民的地理子集,哥伦比亚广播公司大大减少了海地北部地区未经处理的排泄物的处理,同时通过安全和有尊严的工作使生计机会加倍。鉴于其成本效益,这提供了一个机会,通过将CBS整合和交叉补贴到CWIS战略中来实现广泛的卫生覆盖。

One of the major problems confronting public water utilities in Nigeria is how to realise effective piped water tariff revenues collection. This study was therefore conducted to identify the major factors constraining household willingness to pay for piped water tariffs in Nigeria, using Ekiti State as a case study, and possible interventions which might help to improve the situation from the perspective of piped water customers. A tested survey has been used through a representative sampling process. The research findings were checked with additional data from relevant literature and legal documents. Findings revealed that political promise, availability of other water sources, lack of recognition of drinking water as a human right, inadequate method of collecting tariff revenues, and poor response to complaints were the major factors constraining household willingness to pay for piped water tariffs in the studied case in Nigeria. The suggested major possible interventions which might help to improve the situation include the installation of water meters, instituting a customer consultative forum, as well as putting in place improved customer relations. To be effective, it is crucial that public water utilities in Nigeria incorporate these factors into piped water supply decision-making and policy measures.
尼日利亚公共水务公司面临的主要问题之一是如何实现有效的管道水费收入征收。因此,本研究以埃基蒂州为个案研究,旨在确定尼日利亚限制家庭支付管道水费意愿的主要因素,以及可能有助于从管道水客的角度改善这种情况的干预措施。通过有代表性的抽样过程,使用了一项经过测试的调查。研究结果与来自相关文献和法律文件的额外数据进行了核对。调查结果显示,在尼日利亚所研究的案例中,政治承诺、其他水源的可用性、不承认饮用水是一项人权、征收水费收入的方法不充分以及对投诉的反应不佳是制约家庭支付管道水费意愿的主要因素。建议的主要可能的干预措施可能有助于改善这种情况,包括安装水表、设立客户协商论坛,以及建立改善的客户关系。为了提高效率,尼日利亚的公共水务公司将这些因素纳入管道供水决策和政策措施至关重要。

Fighting for water in South Africa: public participation, water rights claiming and strengthening governance 南非的水资源争夺战:公众参与、水权主张和加强治理

Communities in South Africa employ a diverse range of strategies to actively claim their right to water. This paper examines two rights claiming strategies – protest and litigation – through the lens of two case studies. The first case study examines the struggles of the residents of Makhanda, a small town in the predominantly rural Eastern Cape Province, who formed a coalition to advocate for the dissolution of the municipal council for failing to fulfil its constitutional mandate to provide basic services. The second case examines the struggles of the residents of Marikana, an informal settlement in the City of Cape Town, where residents are forced to live in unlit, unhygienic and undignified conditions as a result of inadequate services provision. Although access to water is a justiciable right in South Africa, there is a curious paucity of legal rights mobilisation, with only one court case reaching the Constitutional Court. The article presents the following findings. First, communities employ different methods to claim their water rights, including engagement with government through formal channels, mobilisation, protest, litigation and self-supply. Water is a justiciable human right. Second, litigation is a valuable component of rights-claiming but is most effective if used alongside other strategies like community organisation and protest. Third, water rights can be achieved alongside struggles to secure other rights, like the right to housing, or holding local government accountable. In the two case studies, the legal tools of land expropriation and provincial intervention were employed to indirectly gain access to water services. Finally, community mobilisation, combined with strategic partnerships, plays a critical role in sustaining long-term efforts to claim water rights.
南非的社区采用了各种各样的战略来积极主张他们的水权。本文通过两个案例研究的视角考察了两种权利主张策略——抗议和诉讼。第一个案例研究考察了东开普省以农村为主的小镇Makhanda的居民的斗争,他们组成了一个联盟,主张解散市议会,因为市议会未能履行其提供基本服务的宪法授权。第二个案例考察了马里卡纳居民的挣扎,马里卡纳是开普敦市的一个非正式定居点,由于服务提供不足,那里的居民被迫生活在没有照明、不卫生和不体面的条件下。尽管在南非,获得水是一项可由法院审理的权利,但法律权利的动员却少得可怜,只有一个法庭案件提交宪法法院。这篇文章提出了以下发现。首先,社区采用不同的方法来主张他们的水权,包括通过正式渠道与政府接触、动员、抗议、诉讼和自我供应。水是一项可由法院审理的人权。其次,诉讼是权利主张的一个重要组成部分,但如果与社区组织和抗议等其他策略一起使用,则最有效。第三,水权可以在争取其他权利的同时实现,如住房权或追究地方政府的责任。在这两个案例研究中,土地征用和省级干预的法律工具被用来间接获得供水服务。最后,社区动员与战略伙伴关系相结合,在维持长期争取水权的努力方面发挥着关键作用。

The objective of this research was to explore biocide occurrence in drinking water resources of Honduras. We collected 46 samples from seven drinking water treatment plants (DWTPs) in Honduras during eight sampling events between October 2018 and August 2019. We used high-resolution mass spectrometry to quantify the concentrations of 55 target biocides and estimate the abundance of four priority suspect biocides and five additional high-abundance biocides. We measured 30 of the target biocides, one of the priority suspect biocides, and all five of the high-abundance biocides in at least one of the samples. No correlation was observed between the overall extent of agriculture and biocide occurrence. However, bean production was strongly and significantly correlated with the biocide mixture complexity, as well as with concentrations of aminobenzimidazole and abscisic acid. Biocide mixture complexity was higher during the rainy season than during the dry season, but biocide concentrations were lower during the rainy season. Finally, we found that existing DWTPs are not consistently effective at removing the target biocides. These data represent the first known broad survey of bioicides in drinking water resources of Honduras and demonstrate the need for further study to better understand and manage biocide occurrence.
本研究的目的是探索洪都拉斯饮用水资源中杀生物剂的存在。在2018年10月至2019年8月的八次采样活动中,我们从洪都拉斯的七家饮用水处理厂(DWTP)收集了46个样本。我们使用高分辨率质谱法量化了55种目标杀生物剂的浓度,并估计了四种优先怀疑的杀生物剂和五种额外的高丰度杀生物剂。我们在至少一个样本中测量了30种目标杀生物剂、一种优先怀疑的杀生物剂以及所有五种高丰度杀生物剂。在农业的总体范围和杀生物剂的出现之间没有观察到相关性。然而,大豆产量与杀生物剂混合物的复杂性以及氨基苯并咪唑和脱落酸的浓度密切相关。杀生物剂混合物的复杂性在雨季高于旱季,但杀生物剂浓度在雨季较低。最后,我们发现现有的DWTP在去除目标杀生物剂方面并不总是有效的。这些数据代表了已知的洪都拉斯饮用水资源中杀生物剂的首次广泛调查,并表明需要进一步研究,以更好地了解和管理杀生物剂。

The 2010 legal recognition of the human rights to water and sanitation (UNGA 2010) shaped approaches of many actors working to improve access to water, sanitation and hygiene (WASH). Persistent challenges of poor WASH sustainability, scale and inclusion are increasingly being tackled through systems thinking and system strengthening. However, little has been written about how participatory system analysis and monitoring can equip and empower WASH actors to apply systems thinking, self-assess and course-correct in their own work to improve sustainable WASH for all. WaterAid's Sustainable WASH Services at Scale (SusWASH) programme applies a systems approach, underpinned by human rights principles. In this paper, we share perceptions of local stakeholders, engaged in empowerment evaluation in Cambodia and Uganda, and lessons learned for future initiatives that seek to catalyse WASH system improvements for the realisation of the human rights to water and sanitation. We argue that a systems approach, underpinned by human rights principles, can help advance progress towards inclusive and sustainable WASH for all. Working in this way fosters inclusive, locally led decision-making about how system blockages can be overcome, strengthening local ownership of a shared vision for change and the capacities and skills required to achieve it.
2010年对享有水和环境卫生的人权的法律承认(2010年联合国大会)影响了许多致力于改善获得水、环境卫生和个人卫生(WASH)的行为体的方法。WASH的可持续性、规模和包容性差等持续存在的挑战正越来越多地通过系统思考和加强系统来解决。然而,关于参与式系统分析和监测如何能够装备和授权讲卫生行为者在自己的工作中应用系统思维、自我评估和纠正路线,以改善人人享有可持续的讲卫生活动的文章却很少。水援助组织的大规模可持续讲卫生服务(SusWASH)项目采用了以人权原则为基础的系统方法。在本文中,我们分享了参与柬埔寨和乌干达赋权评估的当地利益相关者的看法,以及为寻求促进WASH系统改进以实现水和卫生设施人权的未来倡议所吸取的经验教训。我们认为,以人权原则为基础的系统方法可以帮助推进面向所有人的包容和可持续的讲卫生运动。以这种方式开展工作,可促进包容性的、由地方主导的关于如何克服系统障碍的决策,加强地方对变革的共同愿景以及实现这一愿景所需的能力和技能的所有权。

Over half of U.S. adults visit parks regularly. Thus, it is important to understand how park drinking water sources affect visitors’ water consumption. In this cross-sectional study of 30 San Francisco Bay Area parks, 4 day-long direct observations of visitors’ drinking water and other beverages were conducted, along with audits of sugar-sweetened beverage access and drinking water source conditions, including flow, appeal, and obstructions. Outcomes were log-transformed to account for skewness, and results were analyzed using mixed-effects regression models to account for matching and clustering by park and observation day. A greater proportion of water sources in low-income parks were unappealing (57.14 vs. 25.00%, P=0.01) or in a poor condition (69.70 vs. 43.24%, P=0.03). A lower proportion of visitors drank water from park fountains that were unappealing (−31%), had poor flow (−22%), or had obstructions (−58%) than those without these conditions. Although only obstructions to the source and water intake were significantly related after adjustment, we observed important effects on water intake by water source appeal and flow. As park water source conditions contribute to water intake, cities should consider installing appealing, functional, and easy to access water sources in parks, particularly those in lower-income neighborhoods.
超过一半的美国成年人经常去公园。因此,了解公园饮用水源如何影响游客的用水是很重要的。在这项针对30个旧金山湾区公园的横断面研究中,对游客的饮用水和其他饮料进行了为期4天的直接观察,并对含糖饮料的获取和饮用水源条件进行了审计,包括流量、吸引力和障碍物。对结果进行对数变换以说明偏倚,并使用混合效应回归模型对结果进行分析,以说明公园和观测日的匹配和聚类。低收入公园中,更大比例的水源没有吸引力(57.14%对25.00%,P=0.01)或条件较差(69.70对43.24%,P=0.03)。与没有这些条件的游客相比,从公园喷泉喝水的游客比例更低(-31%)、流量差(-22%)或有障碍物(-58%)。尽管在调整后,只有水源障碍和取水有显著相关性,但我们观察到水源吸引力和流量对取水的重要影响。由于公园水源条件有助于取水,城市应考虑在公园内安装有吸引力、功能性强、易于使用的水源,尤其是低收入社区的水源。

Kelantan river (Sungai Kelantan in Malaysia) basin is one of the essential catchments as it has a history of flood events. Numerous studies have been conducted in river basin modelling for the prediction of flow and mitigation of flooding events as well as water resource management. Therefore, having multi-step-ahead forecasting for river flow (RF) is of important research interest in this regard. This study presents four different approaches for multi-step-ahead forecasting for the Kelantan RF, using NARX (nonlinear autoregressive with exogenous inputs) neural networks and deep learning recurrent neural networks called LSTM (long short-term memory). The dataset used was obtained in monthly record for 29 years between January 1988 and December 2016. The results shows that two recursive methods using NARX and LSTM are able to do multi-step-ahead forecasting on 52 series of test datasets with NSE (Nash–Sutcliffe efficiency coefficient) values of 0.44 and 0.59 for NARX and LSTM, respectively. For few-step-ahead forecasting, LSTM with direct sequence-to-sequence produces promising results with a good NSE value of 0.75 (in case of two-step-ahead forecasting). However, it needs a larger data size to have better performance in longer-step-ahead forecasting. Compared with other studies, the data used in this study is much smaller.
吉兰丹河(Sungai Kelantan in Malaysia)盆地是一个重要的集水区,因为它有洪水事件的历史。在河流流域建模方面进行了大量研究,以预测流量和减轻洪水事件以及水资源管理。因此,对河流流量进行多步超前预测是这方面的重要研究方向。本研究提出了四种不同的多步超前预测吉兰丹RF的方法,使用NARX(非线性自回归外源性输入)神经网络和称为LSTM(长短期记忆)的深度学习递归神经网络。使用的数据集是1988年1月至2016年12月间29年的月度记录。结果表明,基于NARX和LSTM的递归方法能够对52组测试数据集进行多步超前预测,NARX和LSTM的NSE值分别为0.44和0.59。对于少步提前预测,直接序列到序列的LSTM产生了很好的结果,NSE值为0.75(在两步提前预测的情况下)。然而,它需要更大的数据量才能在更长的步进预测中有更好的表现。与其他研究相比,本研究使用的数据要少得多。

Beyond inclusion: practical lessons on striving for gender and disability transformational changes in WASH systems in Cambodia and Timor-Leste 超越包容性:柬埔寨和东帝汶努力实现讲卫生系统性别和残疾转型的实际经验教训

Women and girls, and people with disabilities are often excluded from governance systems and decision-making on water, sanitation and hygiene (WASH) at all levels – from household to the national level. This paper analyses inclusion and empowerment outcomes for these two groups in three WASH system-strengthening programmes in Cambodia and Timor-Leste. The analysis used WaterAid's ‘Equality and Inclusion Framework’ to assess the quality of inclusion and empowerment outcomes at different levels of WASH systems. The review found that household gender equality changes in Timor-Leste were empowering because they shifted women's and men's roles, relationships and attitudes. It found that women's leadership and disability-inclusive approaches in Cambodia achieved inclusive outcomes because they enhanced women's critical consciousness and increased WASH leaders' awareness of the importance of disability inclusion. There was evidence of either individual/self-empowerment changes or changes to the enabling environment; however, no intervention achieved a comprehensive combination of both. The authors conclude that both individual and environmental outcomes contribute to empowerment outcomes in WASH systems at different levels that can shift gender norms, redistribute power and benefit women and people with disabilities. These findings will enable WASH practitioners to better understand empowerment outcomes and how to integrate them with system-strengthening approaches.
妇女和女童以及残疾人往往被排除在从家庭到国家各级的水、环境卫生和个人卫生(WASH)治理体系和决策之外。本文分析了在柬埔寨和东帝汶的三个讲卫生系统加强项目中对这两个群体的包容和赋权结果。该分析使用了水援助组织的“平等与包容框架”来评估WASH系统不同层次的包容和赋权结果的质量。审查发现,东帝汶家庭性别平等的变化正在赋予权力,因为它们改变了妇女和男子的角色、关系和态度。报告发现,柬埔寨的妇女领导和包容残疾方法取得了包容性成果,因为它们增强了妇女的批判意识,提高了讲卫生运动领导人对包容残疾重要性的认识。有证据表明个人/自我赋权的变化或有利环境的变化;然而,没有任何干预措施能够实现两者的全面结合。作者得出的结论是,个人和环境结果都有助于在不同层次上赋予WASH系统权力,从而改变性别规范、重新分配权力并使妇女和残疾人受益。这些发现将使讲卫生工作人员能够更好地了解赋权成果以及如何将其与加强系统的方法相结合。

The burden of healthcare-associated infections (HAIs) is greater in low- and middle-income countries than in high-income countries. Inadequate environmental health (EH) conditions and work systems contribute to HAIs in countries like Malawi. We collected qualitative data from 48 semi-structured interviews with healthcare workers (HCWs) from 45 healthcare facilities (HCFs) across Malawi and conducted a thematic analysis. The facilitators of infection prevention and control (IPC) practices in HCFs included disinfection practices, patient education, and waste management procedures. HCWs reported barriers such as lack of IPC training, bottlenecks in maintenance and repair, hand hygiene infrastructure, water provision, and personal protective equipment. This is one of the most comprehensive assessments to date of IPC practices and environmental conditions in Malawian HCFs in relation to HCWs. A comprehensive understanding of barriers and facilitators to IPC practices will help decision-makers craft better interventions and policies to support HCWs to protect themselves and their patients.
与高收入国家相比,低收入和中等收入国家的卫生保健相关感染负担更大。不适当的环境卫生条件和工作系统导致了马拉维等国的人道主义援助。我们收集了来自马拉维45家医疗机构(hcf)的48次半结构化访谈的定性数据,并进行了专题分析。氟氯烃感染预防和控制(IPC)措施的促进因素包括消毒措施、患者教育和废物管理程序。卫生保健工作者报告了诸如缺乏IPC培训、维护和修理方面的瓶颈、手卫生基础设施、供水和个人防护装备等障碍。这是迄今为止对IPC做法和马拉维HCFs中与HCWs有关的环境条件进行的最全面的评估之一。全面了解IPC实践的障碍和促进因素将有助于决策者制定更好的干预措施和政策,以支持卫生保健工作者保护自己和患者。
