Out of every ten people in the world today, four do not have adequate sanitation and two don’t have access to clean water. Though preventable, related diseases cause the death of a child every 15 seconds. Water, sanitation and hygiene (WASH) campaigns, with their use of practical thinking and political commitment, can make a huge impact on these figures. Placing people’s initiatives and capacity for self-reliance at the centre of achieving water and sanitation targets, they address the issues of sustainability, affordability and equity. To complement the WASH approach, WSSCC and WaterAid have produced this practical guide on water and sanitation related advocacy work. In its four sections you'll find explanations of the different advocacy tools, practical examples of advocacy work, information on key policy actors and processes, along with how to influence them at local, national and international levels.
