Regional agreements also increasingly recognize the importance of sanitation and the human right to water. The African Charter on Human and Peoples’ Rights, for example, includes the right to “a general satisfactory environment” favorable to peoples’ “development,” which is unattainable without access to water and sanitation. A number of international political declarations and resolutions also include the right to water. For example, the Abuja Declaration adopted at the first Africa-South America Summit in 2006 affirms “the right of our citizens to have access to clean and safe water and sanitation.”
