Soil moisture spatio‑temporal variability under treated and untreated catchment conditions in a fragile tropical highland environment: implication for water security

This research article presents soil moisture variability as influenced by catchment management in the Blue Nile Highlands, Ethiopia. The authors show that improved catchment management can play a critical role in improving agricultural water security in rainfed systems by improving soil moisture availability and storage.

Identifying the Sources of Intestinal Colonization With Extended-Spectrum β-Lactamase-Producing Escherichia coli in Healthy Infants in the Community

This study aimed to identify the sources of ESBL-Ec colonization in children < 1 year old through comparative analysis of E. coli isolates from child stool, child’s mother stool, and point-of-use drinking water from 46 rural households in Bangladesh. Interventions such as improved hygiene practices and a safe drinking water supply may help reduce the transmission of ESBL-Ec at the household level.

Investing in professionalized maintenance to increase social and economic returns from drinking water infrastructure in rural Kenya

This policy brief is based on 10 years of research in Kitui County, Kenya, supported by the REACH programme, the USAID Sustainable WASH Systems Learning Partnership, UNICEF, ESRC and UKAID. It finds the investment case for professionalized maintenance of drinking water infrastructure becomes compelling when factoring in wider social and economic returns.

The unequal distribution of water risks and adaptation benefits in coastal Bangladesh

This article uses a stochastic-optimization model to simulate the impact of flood embankment investments on the distribution of agricultural incomes in coastal Bangladesh. The authors find that the risk of crop loss is greatest for the poor, and make the case for planning models to consider interacting benefits and risks within a local political economy to better inform coastal adaptation decisions.
