This document is a draft of the international agreement to safeguard the Earth's resources, which will be used to create a final declaration at the UN Conference on Sustainable Development (Rio+20) taking place in Rio, Brazil later this year (20–22 June).

This 'zero draft' of the Rio+20 declaration, entitled 'The Future We Want', is based on more than 600 submissions from individual countries, civil society and nongovernmental organisations and other groups.

It outlines advances and setbacks on achieving sustainability since the 1992 Earth Summit, which also took place in Rio, calls for renewed political commitment and outlines a framework for progress towards the green economy. It also calls for support for scientific research and technology transfer in developing countries; strengthened global environmental governance; and sustainable development goals to replace the Millennium Development Goals by 2015.

The document includes an overview of the conference's vision, a framework for action, priority issues and proposals for strengthening implementation.

This policy paper focuses on the depletion of fisheries in the past 20 years, and the urgent need for governments to implement existing policies within the sustainable development framework put forward at the Earth Summit in 1992. It highlights gaps in ocean management, and aims to inform discussions and negotiations in the run-up to the Rio+20 conference in June 2012.

The authors urge the international community to implement commitments made as part of the Earth Summit, the World Summit on Sustainable Development, the Convention on Biological Diversity and the Millennium Development Goals. They also identify eight additional areas for action by the international community as part of a 'pathway to a green economy'.

The paper singles out marine fisheries and marine biodiversity as two key elements of discussions at Rio+20, and argues that there can be no green economy without a blue economy and sustainable marine ecosystems.

This paper discusses how researchers promote the use of research in policy by examining the practices of 'boundary organisations' that cross the boundary between science and politics to facilitate evidence-based policies and programmes. It identifies key lessons for organisations looking to engage policymakers and decision-makers.

The study focuses on the Regional Network on AIDS, Livelihoods and Food Security (RENEWAL), a regional 'network of networks' active in Kenya, South Africa, Uganda, and Zambia which engages government officials on programmes that could inform policies on food, nutrition and HIV/AIDS. It describes the challenges and successes of efforts to promote research in these areas; challenges include adherence to scientific principles while maintaining close relationships with political authority, and ensuring accountability to the communities within which the research is conducted.

The paper offers recommendations to strengthen efforts to get research into policy, and concludes that the concept of a boundary organisation can help researchers engage people and processes that have decision-making power.
