One third of the world’s population lives in coastal areas and rapid development of these areas has meant increased construction of coastal infrastruc- ture (e.g. ports, navigation channels, coastal de- fence) and related activities (e.g. land reclamation, beach nourishment), which has inevitably led to conflicting priorities between coral reef conservation and economic growth. The key impacts of these ac- tivities, if not managed, include:
• Direct loss of coral reef caused by the removal or burial of reefs
• Lethal or sub-lethal stress to corals caused by elevated turbidity and sedimentation rates
Dredging and port construction activities potentially affect not only the site itself, but also surrounding ar- eas, through a large number of impact vectors (e.g. turbid plumes, sedimentation, release of contami- nants, bathymetric changes). Effects may be imme- diate or develop over a longer timeframe and may be temporary or permanent in nature, depending on a large number of factors.

A synthesis biogeographic classification of coastal and continental shelf waters, derived by a broad team of academic, governmental and NGO scientists. It is partly derived from existing classifications. The layer describes a nested hierarchy of 232 ecoregions, within 62 provinces and 12 large realms. The Marine Ecoregions of the World (MEOW) attempt to capture generic patterns of biodiversity across habitats and taxa in intertidal waters and across shallow adjacent benthos and overlying water to a depth of 200 m. The map has been drawn out to the 200 m depth contour, and extended beyond these waters out by a 5 km buffer. The landwards margins are exaggerated and should be clipped to an appropriate coastline by the user. This version (Version 2) should be used for analytical purposes. An alternative version (Version 1) of the MEOW map, drawn to approximately 200 nm is also available from The Nature Conservancy (see Metadata) – this is intended, and quite widely used, for general illustration purposes, but inappropriate for analyses. The ecoregional classification relates primarily to coast and shelf biotas for which a 200 m depth contour (as used in Version 2) is a more accurate indicative boundary.Resource Type: Spatial Data / Maps
Since the late 1970s the UNEP World Conservation Monitoring Centre (UNEP-WCMC) has delivered services that support implementation of international biodiversity-related agreements at global, regional and national levels. These services not only support the work of the agreement secretariats, but also of the advisory and governance bodies, and of governments party to the various agreements. The aim of this paper is to illustrate this work through examples of work we have undertaken.
The support that UNEP-WCMC provides is based on expert understanding of the agreements and how they work, resulting from many years of experience and close relationships with secretariats.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
This paper provides an overview of the current state of knowledge regarding relationships between carbon and biodiversity in tropical forests.Resource Type: Reports
This report reviews the current state of knowledge on the biodiversity impacts (both positive and negative) of biofuel production, with an emphasis on the potential influence of current and future government policies. Although the focus is primarily on first generation biofuels, second and third generation biofuels are also discussed. The potential for sustainability criteria to ameliorate biodiversity impacts is also assessed.Resource Type: Reports
