Abstract/Summary: In the 1950s, shortly after the founding of the People’s Republic of China (PRC), the central government created the Patriotic Health Campaign (PHC) in order to standardize and disseminate health focused educational materials intended to control and prevent infectious diseases (1). “Water improvement”, meaning measures aimed at providing safe drinking water for households in China, was an important part of the PHC. After 60 years of water improvement policies, programs, and investments, the rural water supply sanitation and hygiene in China has improved dramatically, and water-related diseases no longer negatively impact the rural population as they once did. In addition to improvements related to the quantity and quality of the rural water supply, water improvement programs also promoted improved hygiene, sanitation, and other health-related behaviors among rural households. Together, such initiatives have improved the quality of life and the health of hundreds of millions of rural residents, while also contributing to economic and social advancement across rural China (2). The purpose of this article is to describe how the PHC served as a foundation for the expansion and improvement of drinking water supply in rural China, and to summarize the key programs, projects, and initiatives that followed over the last 60 years.

Abstract/Summary: We assessed the regional and seasonal prevalence of HWT practices (including bottled water use) in low-income rural areas in two Chinese provinces, evaluated the microbiological safety of drinking water and associated health outcomes, and estimated the air pollution burden associated with the use of solid fuels for boiling. Methods: We conducted cross-sectional surveys and collected drinking water samples from 1,033 rural households in Guangxi and Henan provinces. Temperature sensors affixed to pots and electric kettles were used to corroborate self-reported boiling frequencies and durations, which were used to model household air pollution (HAP) in terms of estimated particulate matter in aerodynamic diameter () concentrations. Results: Based on summer data collection in both provinces, after controlling for covariates, boiling with electric kettles was associated with the largest log reduction in thermotolerant coliforms (TTCs) ( TTC most probable number), followed by boiling with pots (), and bottled water use (); all were statistically significant (). Boiling with electric kettles was associated with a reduced risk of TTC contamination [risk ratio , ] and reported diarrhea (, ). TTCs were detected in 51% () of bottled water samples. For households boiling with biomass, modeled concentrations averaged (). Discussion: Our findings suggest that where boiling is already common and electricity access is widespread, the promotion of electricity-based boiling may represent a pragmatic stop-gap means of expanding safe water access until centralized, or decentralized, treated drinking water is available; displacing biomass use for water boiling could also reduce HAP concentrations and exposures. Our results also highlight the risks of increasing bottled water use in rural areas, and its potential to displace other sources of safe drinking water, which could in turn hamper efforts in China and other LMICs toward universal and affordable safe water access.

Abstract/Summary:The application of Water Safety Plans (WSPs) in China varies throughout the country. Although pilot WSP projects in China were initiated shortly after WSP was introduced by the World Health Organization (WHO) in 2004, they have yet to be used for water supply facilities at a large scale. To better understand the evolution of WSP application in China, a systematic review was conducted to identify all published WSP related studies in China. Eighteen studies, which included 311 water systems, were included in the final analysis. Risk matrix, water supply risk factors, and other data were extracted and analyzed. Text mining methods were also used to better understand risks that can be addressed by WSPs (both potential and actual risks). This study revealed a number of noteworthy differences between and among urban and rural water systems in China. The primary risks associated with most urban water supply systems tended to be related to mechanical failure/s in the water treatment process. Rural water supply systems appear to suffer from similar problems, but insufficient overall management capacity was more prevalent in rural systems. Overall, the evidence suggests that, to date, the use of WSPs in China has been primarily limited to pilot studies, and full implementation of WSPs in China appears to still be in the early stages. The paper closes with a summary of the key obstacles identified as well as a discussion of policies and technical options which could increase the use of WSPs in both urban and rural China. Among other recommendations, the data indicate that there is strong need for the development and implementation of a simplified WSP approach designed specifically for small rural systems in China.
Intermittent water supply management, household adaptation, & drinking water quality: A comparative study in two Chinese provinces

Abstract/Summary: Intermittent water supply (IWS) is a relatively common phenomenon across the world as well as in rural and peri-urban areas across China, though there has been little IWS-focused research from China published to date. IWS consumers typically adopt a range of strategies to cope with insufficient water supply, poor drinking water quality, and associated inconveniences. In this study, we collected a range of data from small-scale utilities and households in two IWS systems and two continuous water supply (CWS) systems, as well as from comparison groups, in Shandong and Hubei provinces. Data collection included water quality testing, interviews, and surveys on behavioral adaptations, coping strategies, water-related health perceptions, and other metrics of consumer satisfaction. Overall, we found that the IWS coping strategies employed in northern China (Shandong) were associated with generally safe, but inconvenient, water access, whereas adaptation strategies observed in southern China (Hubei) appeared to improve convenience, but not water quality. Compared to the CWS comparison groups, we did not observe significant differences in waterand sanitation-related behaviors in the IWS groups, suggesting interventions to increase adaptive and protective behaviors at the household level might further improve safe water access for households living with IWS. Overall, although the water supply infrastructure in these study areas appeared to be in relatively good condition, in contrast to reported data on IWS systems in other countries, we observed multiple risk factors associated with the water treatment and distribution processes in these IWS systems. Among policy recommendations, our results suggest that the implementation of Water Safety Plans in China would likely improve the management of drinking water treatment and, by extension, safe drinking water supply under conditions of IWS.
The impacts of socioeconomic development on rural drinking water safety in China: A provincial-level comparative analysis
Authors: Li, H., Cohen, A., Li, Z., & Zhang, M.
Publication Year: 2019 | Journal / Publisher: Sustainability
Abstract/Summary:In China, achieving rural drinking water safety—meaning access to a safe, affordable, sufficient, and sustainable drinking water supply—remains a key challenge for government agencies and researchers. Using cross-sectional data at the provincial level, in this paper we examine the impacts of socioeconomic development on drinking water safety in rural China. Using a theoretical framework called Pressure-State-Response (PSR), existing data were organized into state and pressure indicators. Canonical Correlation Analysis was then used to analyze provincial-level relationships between the indicators. Significant drinking-water-safety-related differences were found across provinces. Our analyses suggest that, overall, China’s recent and rapid socioeconomic development yielded substantial benefits for China’s rural drinking water safety. However, this same development also negatively impacted rural drinking water safety via increased groundwater over-abstraction, reductions in water supply, and environmental contamination. The paper closes with a discussion of implications and options for improving drinking water policy, management, and regulation in rural China.
间歇式供水卫生风险及对农村家庭卫生行为影响的初步研究 [Intermittent water supply & associated impacts on drinking water & health-related behaviors in rural households]

Publication Year: 2019 | Journal / Publisher: 环境与健康杂志 [Journal of Environmental & Health]
Abstract/Summary: Objective: To understand the potential health risks associated with intermittent water supply（IWS） in rural area of China generally，and to evaluate the impact of IWS on water and sanitation-related behaviors in rural households specifically. Methods: Two villages with IWS were selected as the study group，one in Shandong province and one in Hubei province，and two neighboring villages with similar socioeconomic conditions and continuous water supply（CWS） were selected as the controls. A total of 600 households were randomly selected in the IWS and CWS groups. From August to November，2017，trained investigators conducted structured interviews to collect a variety of data related to general information of the investigated families，infrastructure of household water and environment，water and sanitation -related behaviors，etc. Data on basic information and operational situation of local drinking water treatment plants was also collected. Results: The primary reported reason for IWS was to decrease the electricity costs associated with water treatment and supply. Insufficient water production and poor clean water storage capacity were also the reasons for IWS. Under conditions of IWS，water was usually supplied one or three times per day during the peak period of water consumption，such as morning，noon and evening. The average duration of water supply in the IWS areas ranged from four hours to 15 hours. Households in the IWS group were much more likely to have water storage facilities （97.0%，194/200） compared with those in the CWS group （47.0%，188/400）. Compared with the CWS group，IWS households had worse measures of personal hygiene，indoor hygiene and household courtyard hygiene，and these differences were statistically significant （P<0.01）. The main types of water storage devices used in IWS households were roof mounted water tanks，water buckets and ceramic water tanks. The percentages of roof -mounted water tanks without mark of qualified quality，household water storage containers without hygienic administrative license for drinking water -related products，clean roof -mounted water tanks and storage containers were 44.6% ，41.5% ，17.9% and 29.7% respectively. Conclusion: Compared with CWS，IWS in rural areas is strongly associated with changes in water-related health behaviors，and unsafe household water storage is the most prominent problem for health risks. Additional attention should be paid to the water safety of rural residents living under conditions of IWS.
Fuel use trends for boiling water in rural China (1992-2012) & environmental health implications: A national cross-sectional study

Abstract/Summary:Survey data from a comprehensive national survey of ∼34 000 households were analyzed for the mix status and transition trajectory of energy for boiling water in rural Chinese households from 1992 to 2012. In 1992, ∼6% of households reported using electricity, biogas, or liquefied petroleum gas (LPG) to boil drinking water; in 2012, the proportion was ∼60%. Income per capita appeared most strongly associated with this transition toward electricity and other clean fuels. Median annual incomes for households using biomass fuels, electric kettles, and LPG were RMB 15 000, 28 000, and 30 000, respectively. Overall, the transition was most pronounced in eastern China, a region which experienced relatively higher rates of economic growth over the same 20-year period. Energy type preferences appear to be highly dependent on fuel accessibility such that coal and straw usage was higher in provinces with higher coal and grain production. These trends suggest that electric kettle use would likely increase from ∼29% (2012) to ∼60% by 2030, at which point <5% of rural households would be expected to boil with solid fuels. Recent evidence suggests that this transition could contribute to reductions in water-related gastrointestinal illness as well as reductions in air pollutant emissions in rural China.
The global risks of increasing reliance on bottled water
Authors: Alasdair Cohen and Isha Ray
Publication Year: 2018 | Journal / Publisher: Nature Sustainability
Abstract/Summary: The rapid growth of bottled water use in low- and middle-income countries, and its normalization as a daily source of drinking water, does not provide a pathway to universal access. Generous and sustained investment in centralized and community utilities remains the most viable means for achieving safe water access for all. We recommend that the international development community and LMIC governments accept that full-cost recovery from a low-income customer base is not realistic, and that they actively invest in regulated utilities or community-scale models as the most sustainable options for delivering universal safe water access. This will take time, of course. Consumer confidence in the safety of utility supplied water should be fortified along the way with water quality reports and, perhaps, ‘marketing’ messages. These recommendations are not new, but they bear repeating in an era of explosive growth in, and de facto normalization of, market-driven approaches to ‘safe water for all’. In the meantime, non-tap treatment options that are known to be effective and affordable, but that may achieve only partial uptake, should be subsidized and more aggressively promoted. If, on the other hand, governments and development agencies allow the bottled water sector to continue meeting the rising demand for safe water in LMICs, then access will indeed expand by 2030, but it will not be reliably safe or universally affordable. The SDG for drinking water is a public commitment, and history is clear: public commitments need public investment.
广西农村家庭饮水行为现状及影响因素分析 [Status & influential factors of drinking water behavior in rural households of Guangxi]
Authors: Luo, Q., Cohen, A., Zhong, G., & Tao, Y.
Publication Year: 2018 | Journal / Publisher: Chinese Journal of Public Health
Abstract/Summary: Objective: To examine the status and the related factors of drinking water behavior among households in rural areas of Guangxi Zhuang Autonomous Region (Guangxi) and to explore effective drinking water treatment methods other than water-boiling in rural households. Methods: We conducted a face-to-face questionnaire survey among 450 households selected with multi-stage stratified random sampling in two counties of Guangxi between 2013 and 2014. We collected information on 10 aspects related to drinking water treatment. We adopted multivariate logistic regression to analyze influencing factors of drinking water behavior among the households. Results: Of all the households surveyed, 47.5 %, 35.0 %,and 17.5 % reported taking boiled, bottled, and unboiled water as drinking water, respectively. There was a significant difference in the proportion of households taking boiled water as drinking water (χ2 = 9.547, P = 0.002). Multivariate logistic regression analyses showed that the households with higher level of relevant knowledge (odds ratio [OR] = 0.290, 95 %confidence interval[95 %CI]:0.097 – 0.865), not discharging sewage at will (OR = 0.295, 95 %CI:0.112 – 0.776), without household water storage (OR = 0.059, 95%CI:0.013 – 0.269), and not preferring to drink boiled water (OR = 0.001, 95 %CI:0.000 – 0.005) were more unlikely to take boiled water as drinking water. Conclusion: In rural areas of Guangxi, the proportion of households using electric kettle to boil water for drinking is not high and a number of households use fuel-based method to boil drinking water or drink bottled water; some households even drink unboiled water; the over standard rate of microbial indicators is relatively high for samples of the drinking water for the households.
Effects of boiling drinking water on diarrhea & pathogen-specific infections in low- & middle-income countries: A systematic review & meta-analysis
Authors: Cohen, A. & Colford, J. M.
Publication Year: 2017 | Journal / Publisher: American Journal of Tropical Medicine & Hygiene
Abstract/Summary: Globally, approximately 2 billion people lack microbiologically safe drinking water. Boiling is the most prevalent household water treatment method, yet evidence of its health impact is limited. To conduct this systematic review, we searched four online databases with no limitations on language or publication date. Studies were eligible if health outcomes were measured for participants who reported consuming boiled and untreated water. We used reported and calculated odds ratios (ORs) and random-effects meta-analysis to estimate pathogen-specific and pooled effects by organism group and nonspecific diarrhea. Heterogeneity and publication bias were assessed using I2, meta-regression, and funnel plots; study quality was also assessed. Of the 1,998 records identified, 27 met inclusion criteria and reported extractable data. We found evidence of a significant protective effect of boiling for Vibrio cholerae infections (OR = 0.31, 95% confidence interval [CI] = 0.13–0.79, N = 4 studies), Blastocystis (OR = 0.35, 95% CI = 0.17–0.69, N = 3), protozoal infections overall (pooled OR = 0.61, 95% CI = 0.43–0.86, N = 11), viral infections overall (pooled OR = 0.83, 95% CI =0.7–0.98, N = 4), and nonspecific diarrheal outcomes (OR = 0.58, 95% CI = 0.45–0.77, N = 7). We found no evidence of a protective effect for helminthic infections. Although our study was limited by the use of self-reported boiling and non-experimental designs, the evidence suggests that boiling provides measurable health benefits for pathogens whose transmission routes are primarily water based. Consequently, we believe a randomized controlled trial of boiling adherence and health outcomes is needed.
Predictors of drinking water boiling & bottled water consumption in rural China: A hierarchical modeling approach
Authors: Cohen, A., Zhang, Q., Luo, Q., Tao, Y., Colford, J. M., & Ray, I.
Publication Year: 2017 | Journal / Publisher: Environmental Science & Technology
Abstract/Summary: Approximately two billion people drink unsafe water. Boiling is the most commonly used household water treatment (HWT) method globally and in China. HWT can make water safer, but sustained adoption is rare and bottled water consumption is growing. To successfully promote HWT, an understanding of associated socioeconomic factors is critical. We collected survey data and water samples from 450 rural households in Guangxi Province, China. Covariates were grouped into blocks to hierarchically construct modified Poisson models and estimate risk ratios (RR) associated with boiling methods, bottled water, and untreated water. Female-headed households were most likely to boil (RR = 1.36, p < 0.01), and among boilers those using electric kettles rather than pots had higher income proxies (e.g., per capita TV ownership RR = 1.42, p < 0.01). Higher-income households with younger, literate, and male heads were more likely to purchase (frequently contaminated) bottled water, or use electric kettles if they boiled. Our findings show that boiling is not an undifferentiated practice, but one with different methods of varying effectiveness, environmental impact, and adoption across socioeconomic strata. Our results can inform programs to promote safer and more efficient boiling using electric kettles, and suggest that if rural China’s economy continues to grow then bottled water use will increase.
Microbiological evaluation of household drinking water treatment in rural China shows benefits of electric kettles: A cross-sectional study
Authors: Cohen, A., Tao, Y., Luo, Q., Zhong, G., Romm, J., Colford, J. M., & Ray, I.
Publication Year: 2015 | Journal / Publisher: PLoS ONE
Abstract: Background – In rural China ~607 million people drink boiled water, yet little is known about prevailing household water treatment (HWT) methods or their effectiveness. Boiling, the most common HWT method globally, is microbiologically effective, but household air pollution (HAP) from burning solid fuels causes cardiovascular and respiratory disease, and black carbon emissions exacerbate climate change. Boiled water is also easily re-contaminated. Our study was designed to identify the HWT methods used in rural China and to evaluate their effectiveness. Methods – We used a geographically stratified cross-sectional design in rural Guangxi Province to collect survey data from 450 households in the summer of 2013. Household drinking water samples were collected and assayed for Thermotolerant Coliforms (TTC), and physicochemical analyses were conducted for village drinking water sources. In the winter of 2013–2104, we surveyed 120 additional households and used remote sensors to corroborate selfreported boiling data. Findings – Our HWT prevalence estimates were: 27.1% boiling with electric kettles, 20.3% boiling with pots, 34.4% purchasing bottled water, and 18.2% drinking untreated water (for these analyses we treated bottled water as a HWT method). Households using electric kettles had the lowest concentrations of TTC (73% lower than households drinking untreated water). Multilevel mixed-effects regression analyses showed that electric kettles were associated with the largest Log10TTC reduction (-0.60, p<0.001), followed by bottled water (-0.45, p<0.001) and pots (-0.44, p<0.01). Compared to households drinking untreated water, electric kettle users also had the lowest risk of having TTC detected in their drinking water (risk ratio, RR = 0.49, 0.34–0.70, p<0.001), followed by bottled water users (RR = 0.70, 0.53–0.93, p<0.05) and households boiling with pots (RR = 0.74, 0.54–1.02, p = 0.06). Conclusion: As far as we are aware, this is the first HWT-focused study in China, and the first to quantify the comparative advantage of boiling with electric kettles over pots. Our results suggest that electric kettles could be used to rapidly expand safe drinking water access and reduce HAP exposure in rural China.

Publication Year: 2014 | Journal / Publisher: United Nations International Fund for Agricultural Development
Abstract/Summary: The Multidimensional Poverty Assessment Tool (MPAT) provides data that can inform all levels of decision making by providing a clearer understanding of rural poverty at the household and village level. As a result, MPAT can significantly strengthen the planning, design, monitoring and evaluation of a project, and thereby contribute to rural poverty reduction.
This brochure explains:
- What MPAT is
- How MPAT works
- When to use MPAT and why
- How to use MPAT
- What resources are available for implementing MPAT
The tool allows project managers, government officials, researchers and others to identify and monitor sectors that require support in order to reduce rural poverty and improve livelihoods. It also provides an objective means of justifying resource allocation or planning priorities. MPAT is based on a bottom-up, participatory approach that reflects communities’ voices, wants and perspectives.
The Multidimensional Poverty Assessment Tool: User’s Guide

Publication Year: 2014 | Journal / Publisher: United Nations International Fund for Agricultural Development
Abstract/Summary: The Multidimensional Poverty Assessment Tool (MPAT) provides a method for simplifying the complexity of rural poverty in order to support poverty alleviation efforts. MPAT uses thoroughly designed and tested purpose-built surveys to collect data on people’s perceptions about fundamental and interconnected aspects of their lives, livelihoods and environments. Standardized indicators, developed through a comprehensive participatory process, are then employed to combine, distil and present these data in an accessible way. MPAT was developed through a participatory, collaborative process based on expert feedback from dozens of international development experts from IFAD, other United Nations agencies, international and regional organizations, and universities from around the world. It was field-tested in countries in both Asia and Africa. In the pages that follow, we explain what MPAT is, how it works and how it is used, providing step-by-step instructions, training materials and other resources. The ultimate objective of this User’s Guide and the accompanying Excel Spreadsheet is to make MPAT a truly free and open-source tool, so that any institution or agency, big or small, may implement MPAT on its own.
Water & poverty in rural China: Developing an instrument to assess the multiple dimensions of water & poverty
Authors: Cohen, A. & Sullivan, C.
Publication Year: 2010 | Journal / Publisher: Ecological Economics
Abstract/Summary: This paper describes the theoretical foundations and development of a multidimensional, water-focused, thematic indicator of rural poverty: The Water, Economy, Investment and Learning Assessment Indicator (WEILAI). The WEILAI approach was specifically designed for application in rural China, to support poverty alleviation project planning, monitoring and evaluation, as well as targeting and prioritization. WEILAI builds primarily on the basic needs framework of poverty alleviation, and on the methodological structure of the Water Poverty Index, to provide a proxy measure of an area’s poverty by assessing eight key poverty sectors, with a strong focus on the components of water-poverty. The WEILAI approach was piloted and implemented in 534 households in China’s mountainous southwest. This paper describes the indicator construction, weighting schemes, methodology, field sites, and statistical validation of the results. In addition, we discuss the results, feedback from in-country project staff, and the likely utility of the tool for project planning, monitoring and evaluation support. The paper concludes with a discussion of WEILAI’s overall utility and ongoing development.
InnoWat: IFAD & rural water investments

Publication Year: 2009 | Journal / Publisher: Rome: United Nations International Fund for Agricultural Development
IFAD is currently engaged in over 230 loan operations in 85 countries. About two thirds of that portfolio is related to community-based natural resource management. Poor rural people and their institutions are at the core of this approach. Water is critical to these men and women pastoralists, fishers, farmers, young and old, part- or full-time, urban or rural, indigenous, tribal or otherwise often marginalized people. Itis the key entry point for improving their livelihoods. Water-related interventions are often linked to the building up or restoring of the asset base – and involve many facets and uses. This holistic view is part of the characterization of IFAD’s approach to water interventions in this fact sheet: rather than considering water solely as an input factor in the production chain, we have preferred to follow water throughout rural people’s livelihoods. This approach, combined with a qualitative analysis of the ongoing 2007/08 loan portfolio, yielded a few surprising insights (table 1).Almost half of all projects (45-50 per cent) involve aspects of water resource management at catchment or watershed levels, and hence beyond the immediate household or community level of use.
The Multidimensional Poverty Assessment Tool: Design, development & application of a new framework for measuring rural poverty
Authors: Cohen, A.
Publication Year: 2009 | Journal / Publisher: United Nations International Fund for Agricultural Development
Abstract/Summary: The purpose of this book is to describe the theoretical foundations upon which the Multidimensional Poverty Assessment Tool (MPAT) was built, to tell the story of how it was created, developed, tested and piloted in rural China and India, and to explain how MPAT can be used to benefit rural communities around the world. Lasting poverty alleviation is achieved by fostering a comprehensive enabling environment within which people have a sufficiently high level of well-being and are able to pursue their livelihood goals based on their aspirations and initiative. To ensure that such environments are in place requires, at a minimum, an understanding of the key constraints rural people face – the fundamental dimensions central to their lives and livelihoods. MPAT does not try to define rural poverty per se; rather it takes a step back from assessment modalities that are overly focused on economic- and consumption-oriented indicators and strives to provide an overview of fundamental and relatively universal dimensions germane to rural livelihoods, rural life, and thus to rural poverty. By summarizing rural communities’ perceptions about key dimensions of rural poverty and focusing them through a quantitative lens, MPAT transparently illuminates problem areas so that all stakeholders can see where deficiencies lie and can begin to discuss which interventions may be most appropriate to address them, based on the local context.
The Rural Water Livelihoods Index. Working Paper
Authors: Sullivan, C., Cohen, A., Faurès, J. M., & Santini, G.
Publication Year: 2008 | Journal / Publisher: Food & Agriculture Organization of the United Nations
Abstract/Summary: The Rural Water Livelihood Index (RWLI) is calculated on the basis of components and indicator values representing each of these four dimensions. The resulting composite index reflects the values for these four dimensions, and on this basis, judgements can be made on how water management might be improved. Each of the four dimensions (components) of the RWLI are represented by two subcomponents, which are combined using a weighted average. In this report, this framework is applied at the national scale, but the approach can be used at any scale as long as appropriate data is available. The purpose of the RWLI is to provide policy makers and planners at the national level an overview of where their country stands relative to others (much like the Human Development Index), and relative to themselves over time, to examine and monitor progress being made as a result of actions taken. This in turn will hopefully allow for better targeted water related interventions to improve rural livelihoods. Through the measurement of these key components, it will be possible to assess which of the four dimensions are most likely to benefit from interventions. Appropriate interventions are context-specific and will have to be identified on a country-by-country basis since contexts differ so widely (i.e., responses to address the reported states will be country and site-specific). However, a general Response Matrix is being developed to provide planners and policy makers a conceptual framework to guide this process and at a macro-level the index values help national-level planners identify which sectors might be most in need of assistance.
