The Centre on Housing Rights and Evictions recently released a report analyzing the Millennium Development Goals (MDGs) related to improved water and sanitation access.
The report, entitled "The significance of human rights in MDG-based policy making on water and sanitation: An application to Kenya, South Africa, Ghana, Sri Lanka and Laos" identifies current trends and critical gaps in such policies related to human rights standards. It also discusses how any gaps in the MDG-based policies can be filled through more explicit and systematic usage of human rights principles.
The report can be accessed here.
