Existence of a national liquid sanitation strategy in Cameroon that is not based on a national sanitation policy -- 3.4.3. Cameroon's national liquid sanitation strategy was the result of a mixed participatory process -- 3.4.4. Cameroon's liquid sanitation strategic planning process undermines national sovereignty -- 3.4.5. Cameroon's national liquid sanitation strategy lacks a "strategic vision" -- 3.4.6.
