Rio summit keeps African hopes alive

African expectations were high for the United Nations Conference on Sustainable Development, the biggest UN summit ever. The conference, held in Rio de Janeiro, Brazil, in June, was “too important to fail,” said UN Secretary-General Ban Ki-moon at the outset. Under the theme of “The Future We Want,” many of the 100 heads of state and more than 40,000 participants demanded ambitious and measurable outcomes to address sustainability issues such as the “green economy,” climate change and so on. Yet when it was over, the “Rio+20” summit, as it was commonly called, left a heated debate over whether those goals had been met.
