The implications of three major new trials for the effect of water, sanitation and hygiene on childhood diarrhea and stunting: a consensus statement. BMC Medicine, August 2019. Our view is that these three new trials do not show that WASH in general cannot influence child linear growth, but they do demonstrate that these specific interventions had no influence in settings where stunting remains an important public health challenge. We support a call for transformative WASH, a comprehensive package of WASH interventions is needed that is tailored to address the local exposure landscape and enteric disease burden.

Effects of complexity of handwashing instructions on handwashing procedure replication in low-income urban slums in Bangladesh: a randomized non-inferiority field trial. Jnl WASH for Dev, Sept 2019. Simple handwashing steps are easier to remember for long time periods compared to complex steps.

Does the source of water for piped supplies affect child health? Evidence from rural Vanuatu. Jnl WASH for Dev, Sept 2019. The results revealed a significant association between diarrhea and the type of water source supplying a piped system.

Do domestic animals contribute to bacterial contamination of infant transmission pathways? Formative evidence from Ethiopia. Journal of Water and Health | in press | 2019. The results imply that interventions aiming to reduce pathogen transmission to infants should think beyond improving WASH and also consider the need to separate infants and animals in the home.

Unavoidable Risks: Local Perspectives on Water Contact Behavior and Implications for Schistosomiasis Control in an Agricultural Region of Northern Senegal. American Journal of Tropical Medicine and Hygiene, August 2019. These findings highlight the capacity of local populations to participate actively in schistosomiasis control programs and the limitations of widespread drug treatment campaigns. Interventions that target the environmental reservoir of disease may provide opportunities to reduce exposure while maintaining resource-dependent livelihoods.


Water and Nutrition:  A Framework for Action. World Bank, August 2019. We present an integrated water and nutrition framework to aid in understanding the various ways that water impacts early child nutrition, drawing on the three dimensions of water security: water quantity, adequate supply of water resources; water quality, water that is free of contamination; and water accessibility, reliable availability to all people, economies, and ecosystems.

Women in Water Utilities: Breaking Barriers. World Bank, August 2019. This study explores these barriers and provides utilities with practical approaches to advance their gender diversity.

Doing More with Less – Smarter Subsidies for Water Supply and Sanitation. World Bank, August 2019. The report reveals that subsidies total around US$320 billion a year globally, excluding China and India – equivalent to around half-a-percent of these countries’ combined GDP.

WELLSPRING: Source Water Resilience and Climate Adaptation. The Nature Conservancy, August 2019. Source Water Protection (SWP) has always been fundamental to water resources management.  Climate change presents a new range of threats, drivers, and uncertainties in how we interact with freshwater ecosystems, but recently developed approaches to cope with climate impacts will ensure that source waters can survive — and thrive — into the future.

Water under fire volume 1: Emergencies, development and peace in fragile and conflict-affected contexts. UNICEF, August 2019. The report presents practical and evidence-based water and sanitation solutions that can be replicated and scaled up. It highlights the need for leadership to bring about immediate action to accelerate water and sanitation service delivery in fragile and conflict-affected contexts.

Government-led monitoring for sustained water service delivery. MWA, August 2019. This position paper presents and discusses WASH sector monitoring in Ethiopia. It highlights recent experiences designed to improve monitoring capacities, processes and systems and outlines opportunities and recommendations for monitoring strengthening activitie
