Key resource: Supporting the least able throughout and beyond CLTS

Since its conception in 1999, Community-Led Total Sanitation (CLTS) has spread to over 60 countries and resulted in millions of people across the world living in open defecation free (ODF) communities.

CLTS enabled communities to own the process and collectively work towards becoming ODF. However, since its implementation at scale a number of challenges have appeared.
