In principle effective delivery of WASH interventions to achive expected outcomes depends on the synergy of the three levels:Local ,national and international.We need the local level commitment and whatever locally available resources,we need national level political,policy and budgetary commitment for going-to-scale and the international support to keep re-igniting the national commitments and linking to the international commitments.Finally , it makes a huge difference with all three levels working complementarily and each adding value to the other.We should not underestimate the value-addition of any of the three levels !
