In June 2012, Brazil will host the United Nations Conference on Sustainable Development, known as Rio+20.
The time is right: there are clear signs that the current development models must be reformulated. Countries—regardless of their wealth—face serious economic and financial crises, social inequality, hunger, unemployment, losses in biodiversity and climate change. These multiple crises point to the timely and urgent need to implement sustainable development models, i.e. national projects that take a balanced and integrated approach to economic growth, social inclusion, and environmental protection.
