The World's oceans play a crucial role for life on the planet. Healthy seas and the services they provide are key to the future development of mankind. Our seas are highly dynamic, structured and complex systems. The seafloor consists of vast shelves and plains with huge mountains, canyons and trenches which dwarf similar structures on land. Ocean currents transport water masses many times larger than all rivers on Earth combined.
In this report, the locations of the most productive fishing grounds in the World - from shallow, coastal waters to the deep and high seas - are compared to projected scenarios of climate change, ocean acidification, coral bleaching, intensity of fisheries, land-based pollution, increase of invasive species infestations and growth in coastal development.Resource Type: Reports
This report documents and analyses good practice examples of ecosystem-based approaches to climate change mitigation and adaptation in Europe. Case studies on ecosystem-based approaches to mitigation involved peatland restoration or conservation (11 projects) and forest conservation, restoration and reforestation (2 projects). Case studies on ecosystem-based approaches to adaptation were divided into inland waters (28 projects), coastal zone (10 projects), agriculture and forestry (11 projects) and cities (9 projects).Resource Type: Reports
UNEP-WCMC, with the financial support of the UN-REDD programme, wrote a paper on biodiversity monitoring for REDD+ published in the journal "Current Opinion in Environmental Sustainability" as part of ongoing work on REDD+ safeguards. The paper observes the following three challenge to biodiversity monitoring for REDD: choosing which aspects of biodiversity to monitor, the difficulty of attributing particular changes to REDD+ and the likely scarcity of resources for biodiversity monitoring. It proposes three responses which may address these challenges: 1) agreed policy targets that identify what should be monitored; 2) making links to existing biodiversity monitoring and to monitoring to estimate GHG emissions and removals; and 3) developing clear theories of change to assist in determining which changes in biodiversity can be attributed to REDD+. The paper is available on the journal website here.Resource Type: Tools / Applications
UNEP-WCMC has been providing technical support to the work of the Convention on Biological Diversity (CBD) on biodiversity and climate change. We carried out three reviews of the recent scientific literature and these fed into the deliberations of the CBD’s Second Ad Hoc Technical Expert Group (AHTEG) on Biodiversity and Climate Change. These reviews, entitled Links between Biodiversity and Climate change: Impacts, Adaptation and Mitigation, have now been published as no 42 of the CBD Technical Series. This publication complements the main report from the CBD AHTEG which appears as CBD Technical Series No. 41 Connecting Biodiversity and Climate Change Mitigation and Adaptation.Resource Type: Reports
A new, systematic review of the evidence on the effectiveness of ecosystem-based approaches to adaptation (EbA) has been carried out to review the effectiveness of EbA and highlight the knowledge gaps. This research was undertaken as a collaboration between BirdLife International, UNEP-WCMC, IIED and the University of Cambridge.
Ecosystem-based approaches to adaptation (EbA) integrate the use of biodiversity and ecosystem services into an overall strategy for helping people adapt to climate change. To date, however, insight into these approaches has often been based on anecdotal case studies of local people’s use of ecosystems. Although they are informative, they can provide rather limited insight in terms of measuring and evaluating the effectiveness of EbA, especially compared with technical or structural adaptation measures. A new, systematic review of EbA evidence has been carried out to interrogate the scientific literature and review studies from around the world, from many different ecosystems and adopting a wide range of adaptation approaches utilising ecosystems. We conclude that EbA approaches are effective and deserve greater policy attention and political support to reach their full potential.Resource Type: Reports
On October 16, at the REDD+ Day of CBD COP 11 in Hyderabad, the UN-REDD programme launched a policy brief focusing on multiple benefits and safeguards under REDD+. The paper elaborated on the use of tools and data to support decisions, and presented examples from implementation in REDD+ countries.
REDD+ is increasingly considered to have the potential to contribute to a range of policy goals in addition to climate change mitigation in the forestry sector. It is also recognized that there are social and environmental risks that may arise as the REDD+ mechanism is being implemented.
What has been less widely acknowledged is that avoiding significant risks and securing additional benefits from REDD+ could be the key to the overall success of the mechanism. By securing benefits beyond carbon, REDD+ can draw support from broader social and political constituencies; demonstrate that it enables a wider range of values to be realized; and generates sustainable income sources.
For governments and other stakeholders to adopt a broader approach to REDD+, a strong evidence base is needed to demonstrate that additional benefits will indeed be achieved, and contributions to national and local priorities accomplished. The Policy Brief outlines a series of analytical approaches that can help provide an evidence base to inform REDD+ decisions. It focuses on addressing environmental risks and benefits, and provides examples from Panama, Nigeria, DRC and Indonesia of where these approaches are already used.
The policy brief was drafted collaboratively with UNEP by UNEP-WCMC as part of their work for the UN-REDD Programme.Resource Type: Tools / Applications
