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.","PeriodicalId":36060,"journal":{"name":"H2Open Journal","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2022-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45468047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":36060,"journal":{"name":"H2Open Journal","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2022-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43346873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":36060,"journal":{"name":"H2Open Journal","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2022-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41718000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":36060,"journal":{"name":"H2Open Journal","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49667829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":36060,"journal":{"name":"H2Open Journal","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43987655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":36060,"journal":{"name":"H2Open Journal","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2022-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46778857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":36060,"journal":{"name":"H2Open Journal","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2022-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43674206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":36060,"journal":{"name":"H2Open Journal","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2022-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46914546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
