The World Mangrove Atlas is the first significant attempt to provide an overview of the distribution of mangroves worldwide. Mapped data were gathered from a wide range of sources and synthesised into a series of regional maps. Related texts describe the species, areal extent and other summary information on the currently known status of mangroves in each country. Produced in association with the International Society for Mangrove Ecosystems (ISME) and the International Tropical Timber Organization (ITTO), The World Mangrove Atlas presents a baseline inventory of mangroves at the end of the twentieth century.Resource Type: Books
Datasets 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.
This grid dataset shows the estimated maximum distribution of dry and seasonally dry topical forest. It has a resolution of ~500m. It is derived from the WWF biome map, the MODIS canopy cover dataset and limited to the tropical zone. This dataset was used in the publication " A global overview of the conservation status of tropical dry forests, 2006. Miles, L., Newton, A., DeFries, R., Ravilious, C., May, I., Blyth, S. Kapos, V. and Gordon, J. Journal of Biogeography 33: 491-505."Resource Type: Spatial Data / Maps
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
This paper reviews the potential for carbon sequestration in dryland ecosystems, which includes forests, but also covers other habitats, such as grasslands, and, importantly, soils. It also considers ways in which carbon storage in drylands affects land degradation issues.Resource Type: Reports
This study demonstrates the utility of carbon isotope discrimination in describing genetic adaptation to arid environments, although it is probably most useful in detecting differentiation when the strategy of the species under investigation is to increase water use efficiency, rather than drought-avoidance. The results suggest that populations on the eastern and western sides of the Andes should be treated as separate management units for the purposes of conserving the genetic resource of this species.Resource Type: Journal Papers
Arctic Flora and Fauna: Status and Conservation is the first truly circumpolar overview of Arctic biodiversity written for the nonspecialist. It provides the reader with a clear understanding of the importance of the Earth's largest ecoregion and its status in the face of a rapidly changing world.Resource Type: Reports
An international team of research scientists has created a peer-reviewed website, http://www.arctic.noaa.gov/reportcard/, which tracks multiple changes in the Arctic environment (Fig. 1). While the 2007 loss of summertime sea ice is the most dramatic example, changes are also seen in the atmosphere, on land and in the ocean, and as shifts in location and abundance of Arctic species.Resource Type: Reports
UNEP-WCMC, with the financial support of the UN-REDD programme, wrote a paper on biodiversity monitoring for REDD+ published in the journal "Current Opinion in Environmental Sustainability" as part of ongoing work on REDD+ safeguards. The paper observes the following three challenge to biodiversity monitoring for REDD: choosing which aspects of biodiversity to monitor, the difficulty of attributing particular changes to REDD+ and the likely scarcity of resources for biodiversity monitoring. It proposes three responses which may address these challenges: 1) agreed policy targets that identify what should be monitored; 2) making links to existing biodiversity monitoring and to monitoring to estimate GHG emissions and removals; and 3) developing clear theories of change to assist in determining which changes in biodiversity can be attributed to REDD+. The paper is available on the journal website here.Resource Type: Tools / Applications
