ABSTRACT
To understand how to move forward to meet the Millennium Development Goals, it is first necessary to analyze what's holding us back. Understanding why 2 in every 10 people in the developing world lack access to water supply, and 5 in 10 lack access to sanitation services, is fundamental to identifying effective strategies for meeting target 10. Clearly, the explanations vary across communities, countries, and regions, but a common set of political, financial, institutional, and technical challenges confronts most developing countries in their quest to expand water supply and sanitation services.
