This report, produced by several UN agencies and programmes, presents tangible recommendations to prioritise and improve the management of the ocean ahead of the Rio+20 conference in June. It aims to provide context for discussions to take place at the conference, and to ensure that ocean and coastal management strategies are incorporated in the new sustainable development approaches that will emerge from Rio+20.

They include plans to mitigate and adapt to ocean acidification; create a 'blue carbon' market for carbon dioxide captured in the ocean; establish institutional mechanisms for protecting habitats and biodiversity not covered by national regulations; adopt a plan to help small island developing states transition towards a green economy; and improve the governance of ocean resources.

The report suggests that there is a strong case for the UN to lead by encouraging improved dialogue, coordination and cooperation among UN agencies, funds and programmes. This could lead to a proposal for a new mechanism for ocean coordination to be put forward at Rio+20.

This report explains how acidification, warming and de-oxygenation are affecting the oceans, and encourages policymakers to mitigate these stressors and prepare appropriate policy statements ahead of Rio+20. It was written with the aim of raising awareness of ocean issues at the COP17 in Durban, South Africa.

The report provides definitions of ocean acidification, warming and de-oxygenation. It includes a guide to ocean impacts predicted to occur this century unless greenhouse gas emissions are substantially reduced, and how these impacts will, in turn, affect the climate via feedback mechanisms. It also outlines recommendations for mitigation, adaptation and research to improve understanding of these stressors.

This report provides a comprehensive overview of the current state of marine biodiversity and responses to environmental threats in islands in the central and western Pacific Ocean. This includes a description of known ocean characteristics in the region and a summary of country-specific climate change adaptation strategies.  

It provides a comprehensive account of environmental statistics and outlines threats to the marine environment in individual island countries, including potential (and perceived) impacts from environmental change (including climate change); habitat loss; invasive species; fishing pressure; sedimentation and increased nutrients from land-use activities.

The report highlights the lack of ocean science data, which makes development of mitigation strategies difficult, and states that improved data as well as human, technical and financial capacity are urgently needed to improve mitigation strategies.
