Research: Water and Sanitation in Post-Emergency Contexts
Action against Hunger has carried out humanitarian programs in Sri Lanka since 1996, helping displaced communities and populations made vulnerable by the ongoing conflict. Immediately after the tsunami of December 26, 2004, Action against Hunger launched emergency operations, adding a new set of concerns to our pre-existing programs. Access to safe drinking water has been a major concern in post-tsunami Sri Lanka, given the widespread contamination of coastal water tables by a salt water from the tsunami’s tidal influx.
To refine and further develop our agency’s capacity to provide sustainable water and sanitation solutions for disaster-affected populations, Action against Hunger has established close working relationships with a number of institutions, such as the Institute for Research and Development, Pierre et Marie Curie University (Paris VI), the French Red Cross and the International Water Management Institute (IWMI). Such partnerships enhance Action Against Hunger’s already extensive water and sanitation expertise, ensuring a healthy sharing of models, methodologies, and approaches to water problems that combine cutting edge research from academia and our field programs.
The application of this research has proven successful in post-tsunami Sri Lanka: Action against Hunger’s teams have been able to improve and optimize the use of water resources for populations in need, a considerable achievement given the extent of aquifer contamination. Our programs have demonstrated the efficacy of geophysical methods such as “Time Domain Electro-Magnetism” (TDEM) which makes it possible to quickly identify where salt water intrusions have taken place. Our close collaboration with research institutes has certainly improved our technical capabilities in the field of water, sanitation and hygiene, enabling us to develop more than 100 water points in previously contaminated areas. Our investments in research and collaboration allows us to develop new techniques and applications in support of communities in dire need.
