At the recent West and Central Africa Regional Rural Sanitation workshop, organised by the CLTS Knowledge Hub, in Saly, Senegal 25-28 June 2018, sanitation practitioners from 15 countries met to discuss regional and national sanitation challenges, to identify lessons learned and share best practices. Many participants identified the different components of the sustainability of open defecation free (ODF) achievements and links with the Sustainable Development Goals (SDGs), specifically with the ‘safely managed sanitation’ target 6.2, as significant challenges.
