The World Economic and Social Survey 2012was launched today in New York. The need for additional and more predictable financing has led to a search for new sources – not as a substitute for aid, but as a complement to it. A number of innovative initiatives have been launched during the past decade, mainly to fund global health programmes aimed at providing immunizations, AIDS and tuberculosis treatments to millions of people in the developing world. WESS 2012 finds that while these initiatives have successfully used new methods to channel development financing to combat diseases, they have hardly yielded any additional funding on top of traditional development assistance.
