This synthesis focuses on estimates of biodiversity change as projected for the 21st century by models or extrapolations based on experiments and observed trends. The term “biodiversity” is used in a broad sense as it is defined in the Convention on Biological Diversity to mean the abundance and distributions of and interactions between genotypes, species, communities, ecosystems and biomes. This synthesis pays particular attention to the interactions between biodiversity and ecosystem services and to critical “tipping points” that could lead to large, rapid and potentially irreversible changes. Comparisons between models are used to estimate the range of projections and to identify sources of uncertainty. Experiments and observed trends are used to check the plausibility of these projections. In addition we have identified possible actions at the local, national and international levels that can be taken to conserve biodiversity. We have called on a wide range of scientists to participate in this synthesis, with the objective to provide decision makers with messages that reflect the consensus of the scientific community and that will aid in the development of policy and management strategies that are ambitious, forward looking and proactive.Resource Type: Reports
The deep sea is the oldest and largest biome on Earth, yet we have little knowledge of the ecosystems and processes in these dark, hidden depths. Only in the last two decades have new technologies enabled scientists to start exploring this last frontier – and their discoveries are fascinating but alarming: the deep sea is teeming with life but is already showing clear signs of anthropogenic impacts despite its remoteness. Many vulnerable deep-sea habitats and communities are being destroyed by fishing and are under threat from increasing exploitation of their mineral and living resources.Resource Type: Reports
Arctic ecosystems are harsh and inhospitable, containing very low species diversity. However, although the habitats are relatively homogeneous throughout the circumpolar Arctic region, differences in species richness and areas of outstanding species richness can be recognised. Analysis of patterns in species diversity can be used to prioritise regions for conservation in the Arctic. Towards this goal, the Conservation of Arctic Flora and Fauna (CAFF) programme has been compiling information on the distribution and abundance of species and ecosystems in the Arctic. The work described in this report was designed to complement other ongoing projects and was included in the CAFF V work plan. It was carried out under an EU fellowship at UNEP-WCMC.Resource Type: Reports
This paper investigates the relationship and potential synergies between monitoring systems for carbon stock changes and multiple benefits from REDD+.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
Substantial amounts of detailed biodiversity data exist for the world, and these data can be used to guide conservation priorities. WCMC compiled key data in order to identify areas of high species richness and endemism.
