Following the December 2004 Tsunami, Action Contre la Faim (ACF) has been implementing an operational research program (to sustainable improve access to drinking water for South Asia populations) in Sri Lanka in partnership with the French Red Cross and the IRD (Institut pour la Recherche et le Développement). As the initial objectives of the project (to produce knowledge, to increase access to safe drinking water for vulnerable populations, to reinforce operational capacities of local actors) could no longer be achieved following the deterioration of the Sri Lanka context with the increase of the conflict in the area of operation, the project was terminated. The research component of the project has been transferred to India until 2009, State of Bangalore, where a PHD student is conducting a research to elaborate methodologies of aquifer studies with geophysical tools. The assessment proposed by ACF for the Ayeyarwaddy Division was to evaluate for the French Red Cross (FRC) purposes, the needs of transferring the FRC Water Research tools (aquifer location) as well as to define and justify in details potential Water Sanitation and Hygiene (WASH) component in the coastal townships of Ayeyarwaddy division, with an additional focus on mainstreaming Disaster Risk Reduction (DRR) for the water and sanitation issues only. It was based on field observations and data provided by NGOs and other actors running programs in this division. It was conducted after the monsoon, starting from 05th to 19th February 2008, managed by a WASH/DRR officer.
