As countries prepare for the ‘Rio+20’ United Nations Conference on Sustainable Development, UNDP is pleased to share this report. It sets out national examples of progress toward sustainable development, from developing countries like Nepal and Niger, as well as emerging economies like South Africa and Croatia. These examples show how social, environmental, and economic progress can be integrated to make a more sustainable future. They illustrate what the future of development programming should look like. Instead of focusing on the tradeoffs between the three strands of development, this report highlights the range and significance of the complementarities between them. It describes ‘triple win’ development policies and programming that regenerates the global commons by integrating social development with economic growth and environmental sustainability.
