Water Supply and Sanitation Policy in Developing Countries Part 2 is the second MOOC in a two-part sequence, and looks at ‘Developing Effective Interventions’. The course seeks to develop analytical skills and deep understanding about a complex, controversial policy problem – one with no simple, easy answers. About half a billion people on our planet still lack access to improved water supplies and about two billion do not have improved sanitation services, leading to an unknown but very large number of avoidable deaths each year from water-related diseases. Millions of dollars are spent on avoidable health care expenditures, and people – mostly women – spend many billions of hours carrying water from sources outside the home. Reducing these costs is a major global challenge for us all in the 21st century. This course seeks to explore the challenging and complex political, economic, social, and technical dimensions of the policy interventions that donors, national governments and water utilities use to address this challenge. This second MOOC consists of the following seven sessions: Session 1: Introduction and how our ‘ancient instincts’ affect water policy interventions. Session 2: Planning better policy interventions: Roles, features and examples of planning protocols. Session 3: Water pricing, tariff design and subsidies. Session 4: Providing information to households and communities to improve water and sanitation conditions. Session 5: Changing the institutions that deliver water and sanitation services: Privatization in developing countries. Session 6: Changing institutions: Lessons from the UK water privatization story. Session 7: Changing institutions: Improving regulation of the water and sanitation sector.
