A group of 53 sanitation and hygiene promotion practitioners met in Bangladesh from 29 to 31 January 2008 to mark the start of the International Year of Sanitation (IYS) by sharing and learning from their peers. Each attending organisation had written a case study on their work and came to the workshop to form a Community of Practice for sharing these experiences, reflecting on the challenges in the region and identifying ways to work together. This publication comprises: an overview of the workshop discussions, the messages that emerged and plans for further joint working; 23 case studies written by practitioners from the region for the workshop; and a concluding paper that takes stock of progress in South Asia and identifies areas where more work remains to be done.
