The document discusses key issues for the Rio+20 UN Conference on Sustainable Development. It argues that the conference should launch international action in several areas: 1) Addressing food security by moving beyond increasing agricultural output to ensuring the right to food, 2) Increasing climate change ambition and emission reductions to stay below agreed warming limits, and 3) Addressing structural inequities and unsustainable development that have led to current crises through investment in new development paths.
