Water, sanitation and hygiene practices associated with improved height-for-age, weight-for-height and weight-for-age z-scores among under-five children in Nepal. BMC Pediatrics, March 23, 2020. This study highlights the potential importance of good WASH practices, and therefore the potential of WASH interventions, to contribute to improved nutritional status in rural Nepal.

Multidimensional Benefits of Improved Sanitation: Evaluating ‘PEE POWER®’ in Kisoro, Uganda. Int. J. Environ. Res. Public Health, March 25, 2020. The results of our assessment show that users felt safer when visiting the toilets at night. Lights provided from the technology also helped with the perceived cleanliness of the toilets. The technology was well accepted, with 97% of the respondents saying that they liked the idea of the Pee Power® technology.

WASH FINANCING

Blended Finance in Cambodian Rural Water Supply: Triggering Private Water Operator Investment with Viability Gap Funding. MarketLinks, March 2020. Palladium’s Investing in Infrastructure (3i) program decided to test a known blended finance tool — viability gap funding (VGF) — in the Cambodian water market. VGF is a subsidy tool that governments use to incentivize private investment in infrastructure projects that are economically and socially viable but are not financially viable in the short term.

WATER SECURITY

A Conversation with Rodolfo Camacho on Using Data for Water Security. New Security Beat, March 2020. Camacho, Project Director at Winrock International and Chief of Party for USAID’s Sustainable Water Partnership (SWP), sat down with Lauren Herzer Risi, Project Director of the Environmental Change & Security Program to discuss the importance of big data and machine learning on improving water security.

WATER QUALITY

Assessing Drinking Water Quality at the Point of Collection and within Household Storage Containers in the Hilly Rural Areas of Mid and Far-Western Nepal. Int. J. Environ. Res. Public Health, March 25, 2020. Households’ perceptions of their drinking water quality were mostly influenced by the water’s visual appearance, and these perceptions in general motivated their use of HWT. Improving water quality within the distribution network and promoting safer water handling practices are proposed to reduce the health risk due to consumption of contaminated water in this setting.

Novel methods for global water safety monitoring: comparative analysis of low-cost, field-ready E. coli assays. npj Clean Water, March 30, 2020. We evaluated two promising E. coli methods that may have potential in at-scale global water quality monitoring: a modified membrane filtration test followed by incubation on pre-prepared plates with dehydrated culture medium (CompactDryTM), and 10 and 100 ml presence–absence tests using the open-source Aquatest medium (AT).
