Now Released: First-Ever Global Map of Total Human Effect on Oceans
Date:
April 1, 2008

The  world’s oceans are significantly impacted by human activities, with no unaffected areas remaining, according to the first global-scale study of human influence on marine ecosystems. However, there are still large areas that are relatively unaffected by humans, particularly near the poles.

Researchers overlaid maps of 17 different activities such as fishing, climate change, and pollution, to produce a composite map of human influence on the oceans of the world.

The report, “A Global Map of Human Impact on Marine Ecosystems,“ was published in the February 15 issue of Science. Data is available from the Web site. The project had its genesis in a working group at the National Center for Ecological Analysis and Synthesis in Santa Barbara, California.

New Human Footprint Data Available

Date: March 17, 2008

CIESIN has released an updated version of The Human Footprint, a data set that aims to measure the extent of human influence on the Earth’s surface. First produced in 2002 by CIESIN with the Wildlife Conservation Society, this new version of The Human Footprint uses updated data on human population density, land transformation, human access, electrical power infrastructure, and settlements. Urban boundaries are drawn from CIESIN’s urban population data (Global Rural-Urban Mapping Project (GRUMP)), which is more recent (circa 2000) and is also a better representation of urban boundaries than what was used in the first version. The population density data (Global Population of the World (GPWv3)), produced by the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN, also have a number of improvements over the data used in the earlier version. The roads data are more complete, particularly concerning roads in Africa and Latin America; a greater number of navigable rivers is included; and more extensive land cover data are used.

Data available for download include the Human Influence Index, Human Footprint, and the Last of the Wild data sets.

2006 IUCN Red List Reveals Continuing Declines
Date:
May 2, 2006

The 2006 IUCN Red List of Threatened Species brings into focus the ongoing decline of the earth's biodiversity. Widely recognized as the most authoritative assessment of the global status of plants and animals, the Red List provides an accurate measure of progress, or lack of it, in achieving the globally agreed target to significantly reduce the current rate of biodiversity loss by 2010. Of the 40,177 species worldwide assessed using the IUCN Red List criteria, 16,119 are now listed as threatened with extinction. This includes one in three amphibians and a quarter of the world's coniferous trees, on top of the one in eight birds and one in four mammals known to be in jeopardy. The total number of species declared officially Extinct is 784 and a further 65 are only found in captivity or cultivation.

Convention on Biological Diversity (CBD) Defines Indicators to Meet 2010 Target
Date:  March 2006 (CoP VII)

The CBD Conference of the Parties agreed on a limited number of trial indicators, to assess progress at the global level towards the 2010 target, and to effectively communicate trends in biodiversity related to the three objectives of the Convention (paragraphs 3 and 4 of decision VII/30). The 2010 target is "to achieve by 2010 a significant reduction of the current rate of biodiversity loss at the global, regional and national level as a contribution to poverty alleviation and to the benefit of all life on earth." The COP agreed on eight indicators for immediate testing and another 13 indicators requiring further development.
