Welcome to the Anthropocene: Rio+20 and the Meaning Sustainable Development Introduction

From June 20 to 22, 2012, 45,000 participants from governments, the private sector, nongovernmental organizations, and major groups met in Rio De Janeiro for the "Rio+20" United Nations Conference on Sustainable Development. The outcome document titled "The Future We Want" alludes to a grand vision for addressing global challenges in the framework of sustainable development: economic, social, and environmental. But the 53-page long document only reiterates promises made elsewhere. It fails to lay out a coherent roadmap forward, much less to define binding targets with specific deadlines. The declaration, however, does reflect a changing political reality in international negotiations. Developing countries are playing a much more assertive role in pushing poverty eradication as the overarching priority than at any time before. Rio+20 furthermore presents a snapshot of the divers interests and voices that shape the discourse on sustainable development, 20 years after the original 1992 Rio Conference launched the debate.
