In Nigeria, diarrheal diseases are the third leading cause of mortality, accounting for over 75,000 deaths of children aged 1-59 months in 2015 (WHO, 2016).  From 2012 to 2016, Action Against Hunger worked with local authorities to trigger 138 communities in Yobe State, Northern Nigeria, using the Community-Led Total Sanitation methodology. The objective of this approach is to empower the community to realise the negative impacts of open defecation on health and well-being, and thus mobilise itself to eliminate open defecation and improve sanitation with limited external intervention.
