WSSCC works closely with highly respected professionals in the water, sanitation and hygiene arena who are nominated by their peers and appointed by the Executive Director to be volunteer experts, known as national coordinators. The 16 national coordinators work in priority countries in Africa and Asia and are an important and distinguishing feature of WSSCC. This report is focused on the WSSCC national coordinators, the vital work they lead at country level and their considerable ongoing impact. National coordinators possess local knowledge of what is happening on the ground and understand the dynamics of their particular country contexts. Their day jobs range from heading up national NGOs to holding senior positions in government offices or consultancy firms. With this kind of combination of experience, capacities, exposure and contexts, the national coordinators bring a wide range of rich knowledge and ways of working to the WSSCC mission that allows our work to reach sectors and partners that would not otherwise be possible.
