Written by UNEP-WCMC and UNEP-FI, this paper provides an overview of biodiversity offsets as a mitigation mechanism and examples of the different types of global regulatory and voluntary initiatives adopting this concept, as well as highlighting some existing challenges and opportunities.Resource Type: Reports
Produced jointly between UNEP-WCMC and UNEP’s Division of Technology, Industry and Economics, this document reviews the business case for biodiversity; provides an overview of impacts by sector and highlights existing and potential opportunities for companies. The document covers a wide range of sectors and complements existing and ongoing work on business and biodiversity.Resource Type: Reports
The World Atlas of Coral Reefs is an invaluable resource to be enjoyed and used by a broad audience ranging from global travellers to scientists, including all those with an interest in the natural history of coral reefs, resource managers, travel organisations and university students. The book also caters to the needs of amateur divers and boat owners as a key information resource.Resource Type: Books
National Parks and other protected areas not only provide a safe haven for biodiversity, they provide benefits to local communities and preserve some of the most beautiful places on our planet. ‘Coverage of protected areas’ is also a specific indicator in the 2010 Target of the Convention on Biological Diversity.
Obtaining the data necessary to monitor trends in protected areas requires a massive effort by national authorities to compile, analyse and then distribute this data to the centralised depository of the World Database on Protected Areas (WDPA). With a living and growing system of protected areas that now exceed 100,000 sites covering 19 million square kilometres, you can imagine that this is no small task!
This report is a contribution to the UN’s International Year of Biodiversity and is a complement to the UNEP-hosted Economics of Ecosystems and Biodiversity (TEEB) which is bringing visibility to the wealth of the world’s natural capital. It documents over 30 successful case studies referencing thousands of restoration projects ranging from deserts and rainforests to rivers and coasts. The report confirms that restoration is not only possible but can prove highly proftable in terms of public savings; returns and the broad objectives of overcoming poverty and achieving sustainability. It also provides important recommendations on how to avoid pitfalls and how to minimize risks to ensure successful restoration.Resource Type: Reports
In 2008 UNEP-WCMC produced a report with a consortium of Chinese and international partners on research needs for reducing poverty through better ecosystem management in China. This work was for DFID, NERC and ESRC of the UK government, as a contribution to their design of a proposed international research programme on ecosystem services for poverty alleviation (www.nerc.ac.uk/research/programmes/espa/) The China ESPA report identified that China’s great progress in poverty reduction has slowed, as the remaining poor tend to be found in environments of low productivity or high risk of ecosystem degradation, such as mountains, grasslands and deserts. The government of China is investing heavily in poverty reduction and environmental management, with opportunities for improving the synergies between these activities. Research needs include better understanding of ecosystem functioning for multiple services, and development of methods to analyse policies and projects for both poverty reduction and supply of ecosystem services.Resource Type: Reports
The threat posed to coral reefs by biological invasion is unlikely to diminish and should therefore be considered in analyses of the effectiveness of Marine Protected Areas.Resource Type: Journal Papers
Global and regional coral reef area statistics are of considerable value in fields ranging from global environmental change to fisheries to conservation. Although widely quoted, Smith's 1978 figure of 600 000rkm2 is only an approximate calculation. The World Conservation Monitoring Centre has prepared a new estimate of reef coverage by mapping emergent reef crest and very shallow reef systems. These data were rasterised, using 1rkm grid squares, as a means of reducing errors arising from variation in scale. Global and regional reef coverages were calculated from the resultant grid. The total global area is estimated at 255 000rkm2, considerably lower than many previous estimates. Variation in reef area estimates is, in part, a function of variation in reef definition.Resource Type: Journal Papers
The countries affected by the 2004 Asian tsunami contain the most diverse and extensive coral reefs and mangroves of the Indian Ocean, and some of the richest in the world. Not only are these ecosystems among the most threatened in the world, they also provide numerous essential ecosystem services.
It is thus not surprising that reefs and mangroves received widespread attention after the tsunami, with three principal questions posed: Are the tsunami's impacts on reefs and mangroves a further threat to their future survival? Did reefs and mangroves play a role in shoreline protection and reduce structural damage and human mortality? How could reconstruction efforts include actions to maintain these ecosystems and reduce further threats to them?Resource Type: Journal Papers
Coral reefs are the most biologically diverse of shallow water marine ecosystems but are being degraded worldwide by human activities and climate warming. Analyses of the geographic ranges of 3235 species of reef fish, corals, snails, and lobsters revealed that between 7.2 and 53.6 of each taxon have highly restricted ranges, rendering them vulnerable to extinction. Restricted-range species are clustered into centers of endemism, like those described for terrestrial taxa. The 10 richest centers of endemism cover 15.8 of the world's coral reefs (0.012 of the oceans) but include between 44.8 and 54.2 of the restricted-range species. Many occur in regions where reefs are being severely affected by people, potentially leading to numerous extinctions. Threatened centers of endemism are major biodiversity hotspots, and conservation efforts targeted toward them could help avert the loss of tropical reef biodiversity.Resource Type: Journal Papers
