The Millennium Development Goals, adopted at the UN Millennium Summit in 2000, are the world's targets for dramatically reducing extreme poverty in its many dimensions by 2015 income poverty, hunger, disease, exclusion, lack of infrastructure and shelter while promoting gender equality, education, health and environmental sustainability. These bold goals can be met in all parts of the world if nations follow through on their commitments to work together to meet them. Achieving the Millennium Development Goals offers the prospect of a more secure, just, and prosperous world for all. The UN Millennium Project was commissioned by United Nations Secretary-General Kofi Annan to develop a practical plan of action to meet the Millennium Development Goals. As an independent advisory body directed by Professor Jeffrey D. Sachs, the UN Millennium Project submitted its recommendations to the UN Secretary General in January 2005. The core of the UN Millennium Project's work has been carried out by 10 thematic Task Forces comprising more than 250 experts from around the world, including scientists, development practitioners, parliamentarians, policymakers, and representatives from civil society, UN agencies, the World Bank, the IMF, and the private sector. In this report the UN Millennium Project Task Force on Water and Sanitation outlines the bold yet practical actions that are needed to increase access to water and sanitation. The report underscores the need to focus on the global sanitation crisis, which contributes to the death of 3900 children each day, improve domestic water supply, and invest in integrated development and management of water resources, all of which are necessary for countries to reduce poverty and hunger, improve health, advance gender equality and ensure environmental sustainability. Implementing the recommendations of this report will allow all countries to halve the proportion of people without access to safe water and sanitation by 2015.
