Seagrasses are unique as they are the only marine flowering plants. Seagrass beds form complex physical structures and are a highly productive ecosystem. This enables them to support a considerable biomass and diversity of associated species. For the first time the World Atlas of Seagrasses summarises the opinion and science of the world's leading experts on the global status of the ecosystem.
The Atlas is a collaboration of more than 50 authors from 25 nations. Fully illustrated, the Atlas contains the first global and regional maps of seagrass distribution and a wealth of information on key issues concerning this 'forgotten' ecosystem.Resource Type: Books
UNEP-WCMC, with support from the German Federal Agency for Nature Conservation (BfN), has launched a new website highlighting the potential for actions on reducing emissions from land use change to secure additional important benefits for biodiversity and ecosystem services (co-benefits). The website demonstrates the utility of spatial analyses to assist decision makers in identifying areas where high carbon, high biodiversity priority, and ecosystem service values overlap, which represent opportunities for securing co-benefits. It showcases UNEP-WCMC’s recent work with in-country partners on developing such analyses and includes an interactive mapping tool that allows users to explore the spatial relationships between carbon and co-benefits.Resource Type: Tools / Applications
Co‐benefits, often called multiple benefits, are the positive impacts of Reducing Emissions from Deforestation and Forest Degradation (REDD) that are additional to emissions reductions. These include ecosystem and social benefits such as biodiversity and non‐timber forest products. Potential co‐benefits from REDD are widely relevant in Tanzania, where forests and woodlands support the livelihoods of 87% of the rural poor (Milledge et al. 2007). Conserving biodiversity also promotes the continued provision of these benefits under environmental change (Campbell et al. 2009), thus increasing resilience to climate change. Depending on where REDD action is taken, the co‐benefits delivered will vary. Simple mapping tools can help identify how carbon, other services and pressures such as fire are distributed and relate to each other.
Here, we map the distribution of carbon stocks in relation to the possible co‐benefits of REDD, alongside other relevant factors. A new map of carbon in Tanzania’s ecosystems has been produced for this analysis.Resource Type: Reports
Emissions from land use change mainly forest loss contribute 17 4% of total change, loss, 17.4% anthropogenic greenhouse gas emissions (IPCC 2007). The UN Framework Convention on Climate Change is currently discussing incentives for Reducing Emissions from Deforestation and forest Degradation in developing countries (REDD). In addition to securing carbon, REDD can deliver co‐benefits, including conservation of forest biodiversity and maintenance of ecosystem services. To help secure co‐benefits, it is useful to find out where high carbon, high biodiversity priority and ecosystem service values overlap.Resource Type: Posters
Coral reefs are a critical global resource, both biologically, and in socio-economic terms. Coral reefs are also highly sensitive to climatic influences and appear to number among the most sensitive of all ecosystems to temperature changes, exhibiting the phenomenon known as coral bleaching when stressed by higher than normal sea temperatures.Resource Type: Reports
This first analysis of the likely impact of climate change on biodiversity demonstrates the impact on Arctic waterbirds. The Arctic will be the biome most affected by climate change and hence waterbird species, most of which are entirely reliant on Arctic habitats, are particularly vulnerable.Resource Type: Reports
