Sustainable development for health: Rio and beyond
The Lancet

Preview
Compared with 1992, when the historic Earth Summit took place, “the challenges facing humanity today are much the same, only larger”, wrote UN Secretary-General Ban Ki-moon in an opinion piece published in the New York Times last month. Some 50 000 delegates are expected to reconvene in Rio de Janeiro, Brazil, later this month (June 20–22) for the UN Conference on Sustainable Development (Rio+20). At what will certainly be a tumultuous gathering, policies focused on tackling global poverty in novel ways through sustainable economic growth, social inclusion, and environmental protection are expected to be proposed.
