This JNCC-commissioned report highlights biodiversity impacts of indirect land use change caused by biofuel production. Increased demand for biofuels to achieve renewable energy targets is putting pressure on biodiversity worldwide. The research highlights a new and so far little understood threat: the impact of indirect land use change on biodiversity.
Resource Type: Tools / ApplicationsHow do bioenergy policies relate to the REDD+ mechanism, is the subject of this new Bioenergy Issue Paper jointly authored by UNEP and UNEP-WCMC.
The potential contribution of bioenergy in reducing global emissions of greenhouse gases has been widely debated, both in terms of climate change mitigation potential and potential risk of increases in greenhouse gas emissions resulting from land use change. This has raised the question of how bioenergy policies relate to the REDD+ mechanism developed under the UNFCCC. This issue paper examines the complexity of this relationship and stresses the importance of ensuring policy coherence across the relevant sectors.

Resource Type: Tools / ApplicationsDatasets Available from UNEP-WCMC: Excluding WDPA
Access to UNEP-WCMC datasets is provided on the understanding that you read and consent to be bound by the Terms and Conditions attached. For the purposes of this Agreement the “Data” comprise any of the spatial data and associated attribute data downloadable from the UNEP-WCMC website, excluding the World Database on Protected Areas.
The dataset contained in this map represents the global distribution of warm water coral reefs. It has been created from multiple sources and supercedes the dataset used in the World Atlas of Coral Reefs (2001), although some aspects of this product still originate from that datasource. This global coral reef dataset should be seen an 'interim' global product. It has been compiled from a number of data sources which have been merged together by UNEP-WCMC. The Approximate % coverage of data sources are as follows - Millennium Coral Reefs (Unvalidated) 50% - Millennium Coral Reefs (Validated) 30 % - Other sources 20%.
Resource Type: Spatial Data / MapsDiseases affecting coral reefs have increased in frequency and severity in recent decades. These diseases combine with existing human induced impacts on coral reefs to compromise their health and sustainability. Up to date information on the global abundance and distribution of diseases is critical in order to predict these impacts, to understand how current reef management practices and human impacts affect the spread and severity of diseases, and to inform policy and management decision making.
Resource Type: Tools / Applications 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.
