My past and present work and research focus on M&E and poverty metrics, water management, and drinking water treatment, in the context of rural poverty and development. Geographically, I work mostly in Asia.
My studies and research at Berkeley are an interdisciplinary blend of Environmental Science, Public Health and Behavioral/Social Science, with four main areas:
- Water, Sanitation & Hygiene (WASH) and rural development policy
- Poverty metrics/indicators, monitoring & evaluation (M&E), and intervention design
- Water contamination and affordable drinking water treatment
- Innovation Diffusion and behavior change theory
My doctoral research is focused on point-of-use household water treatment (HWT), and the health and environmental implications of boiling (as a method of HWT). ~300 million rural Chinese still lack access to safe drinking water and most of China’s rural population (~700 million) regularly boil their water. While boiling inactivates pathogens, fuel combustion contributes to respiratory ailments via indoor air pollution (and fuel harvesting and combustion can contribute to environmental damage). Furthermore, women and children are often tasked with water and fuel collection, and are disproportionately exposed to indoor air pollution (from boiling water and cooking).
In addition to evaluating the real-world effectiveness of boiling on drinking water quality in rural China, my objective is to better understand the relationships and drivers between water-related behaviors and beliefs, drinking water quality, fuel use, gender, and poverty in rural China – with the goal of improving access to safe water, reducing exposure to indoor air pollution, and potentially improving environmental health. To investigate these issues, I work with the National Center for Rural Water Supply Technical Guidance (NCRWSTG), an agency of the Chinese Center for Disease Control & Prevention (CCDC), and their CCDC and government counterparts in Guangxi Province.
During the summer of 2013 we collected data from 450 households across 15 villages in Guangxi Province using a geographically stratified, population-weighted, cross-sectional design. The Multidimensional Poverty Assessment Tool (www.ifad.org/mpat) surveys were used to collect demographic and poverty-related data alongside purpose-designed survey questions about drinking water practices and preferences, fuel use, boiling behaviors, household ventilation, etc. Drinking water samples were collected from every household and analyzed for microbial contaminants. Physicochemical analysis was conducted for each village’s primary drinking water source/s. Data collection was repeated in a subset of villages during the 2013-2014 winter to address seasonality, and remote temperature sensors (on kettles and pots) were used to corroborate household survey responses about boiling frequency and duration.
Analysis and publication preparation are now underway. The CCDC has already scaled up our research design to Henan Province (data collection completed Summer of 2014) and will use our results and analysis to inform future rural water policies in China. Hopefully, these findings will also be relevant for other countries with relatively high rates of water boiling in rural areas (e.g., Mexico, Vietnam), and will inform the design of future HWT-promotion interventions and WASH projects.
