Using structural equation modelling to untangle sanitation, water and hygiene pathways for intervention improvements in height-for-age in children <5 years old. International Journal of Epidemiology, October 2019. Authors: Heather Reese, Sheela S Sinharoy, Thomas Clasen – Our finding, that water impacts HAZ through the sanitation pathway, is an important and actionable insight for WaSH programming.

Review of drivers and barriers of water and sanitation policies for urban informal settlements in low-income and middle-income countries. Utilities Policy, October 2019. Authors: Sheela S.Sinharoy, Rachel Pittluck, Thomas Clasen – Ensuring responsive water and sanitation policies for informal settlements will require inter-disciplinary collaboration and both top-down and bottom-up approaches.

A localized sanitation status index as a proxy for fecal contamination in urban Maputo, Mozambique. PLoS One, October 2019. Authors: Drew Capone, Zaida Adriano, David Berendes, Oliver Cumming, Robert Dreibelbis, David A. Holcomb, Jackie Knee, Ian Ross, Joe Brown – This study was funded by the United States Agency for International Development under a Translating Research into Action and the Bill and Melinda Gates Foundation.

Household coping strategies associated with unreliable water supplies and diarrhea in Ecuador, an upper-middle-income country. Water Research, November 2019. Unreliable water supplies influence household water treatment and storage. The relationship between unreliable water supplies and diarrheal disease is not well understood. Increased storage and use of unprotected secondary sources were associated with diarrhea.

The regulation of onsite sanitation in Maputo, Mozambique. Utilities Policy, December 2019. Authors: Johann Weststrate, Alberto Gianolib, Jasper Eshuis,  Geske DijkstraaIdrisse – In Mozambique, national regulations do not include standards for pit latrines. Regulation may be ineffective in poor areas if all costs of implementation are passed on to users.


Changing urban sanitation infrastructure through behaviour change interventions in Lusaka, Zambia. SHARE Project, October 2019. Behavior change interventions have the potential to support urban sanitation programs in challenging settings.


3 ways India can tackle its human-waste problem. WEF, October 25, 2019. The Forum of Young Global Leaders has joined hands with Population Services International to scale up a pilot successfully implemented in Bihar’s capital, Patna, addressing the city’s fecal sludge management challenges.

Collective action towards WASH systems strengthening. WASHfunders, November 2019. Author: Alec Shannon – One such organization is Agenda for Change, a collaboration of like-minded organizations that have adopted a set of common principles and approaches to support national and local governments in strengthening the systems required to deliver universal and sustained access to WASH services.

Engineering a world of safer water. CU Boulder Today, November 2019. No matter where you are in the world, Professor Karl Linden wants you to be able to turn on a tap and receive clean drinking water.

5 myths drowning out progress on WASH. Devex, November 4, 2019.


Faecal sludge management landscape in South Asia. WaterAid, September 2019. The goal of this study was to understand key elements of the enabling framework for fecal sludge management (FSM) at country level: policies and regulations, institutional roles and responsibilities, coordination, equity, inclusion, funding and financial considerations.


November 18, 2019 – UNC Water Institute Webinar – Protecting the Urban Environment from Fecal Contamination –  Decreasing environmental fecal contamination has a non-linear relationship with diarrhea rates; low environmental contamination levels must be achieved before diarrheal disease can be reduced. Sanitation systems without adequate fecal sludge management or sewage treatment only move pollution problems to another location.

April 21-23, 2020 – Abuja, Nigeria – ICT4D Conference Call for Speakers – Water in sustainable landscapes | WASH in humanitarian and development contexts | Improving water finance and governance – Apply to speak at the 12th ICT4D Conference in Abuja, Nigeria, until November 30th, 2019.
