The Millennium Project was commissioned by the United Nations Secretary-General in 2002 to develop a concrete action plan for the world to achieve the Millennium Development Goals and to reverse the grinding poverty, hunger and disease affecting billions of people. In 2005, the independent advisory body headed by Professor Jeffrey Sachs, presented its final recommendations to the Secretary-General in a synthesis volume Investing in Development: A Practical Plan to Achieve the Millennium Development Goals. The bulk of the Project's work was carried out by 10 thematic Task Forces, each of which also presented its own detailed recommendations in January 2005. The Task Forces comprised a total of more than 250 experts from around the world including: researchers and scientists; policymakers; representatives of NGOs, UN agencies, the World Bank, IMF and the private sector.
