WASH is a significant part of World Vision's effort to enhance the well-being of children and communities around the world by addressing issues of poverty and injustice. Through WASH programmes, World Vision is privileged to serve and partner with communities in multiple faith contexts around the world. Eighty-five percent of the world’s population is religious, and most of the world’s poor communities tend to be very religious. Because World Vision is an openly Christian, faith-based organisation, its WASH programmes are uniquely positioned to engage effectively with the heart and spirituality of the communities it serves. This learning brief summarises key approaches and learnings on faith engagement and WASH at World Vision.
