The creation and significance of subnational infant mortality data developed by CIESIN are the focus of a new article published in the journal Population, Space, and Place. Authored by former CIESIN staff Adam Storeygard and Deborah Balk, with CIESIN deputy director, Marc Levy, and Glenn Deane, "The Global Distribution of Infant Mortality: A Subnational Spatial View," explains how subnational measures of infant mortality can serve as a useful, spatially-precise indicator of poverty. Prior to the production of this data set, global poverty measures had been available only at the national level; increased spatial precision at the subnational level is especially helpful when examining interactions between poverty and factors that do not conform to national borders, such as climate zones, eco-regions, and natural hazard exposure. The article describes how the data set was produced, delineates its known strengths and weaknesses, and reports some spatial patterns that emerge, such as the relationship between coastal proximity and poverty rates. The subnational poverty data set was produced in 2004-2005 as a part of The Global Distribution of Poverty project, a joint effort of the World Bank, the Earth Institute at Columbia University, and the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN. The data set has been used in a number of global assessment exercises, including the UN Millennium Development Project and the Millennium Ecosystem Assessment.

CIESIN deputy director Marc Levy participated in a number of panels at the 2008 International Studies Association (ISA) meeting in San Francisco March 25-28. He chaired a panel on multilateral governance in the ASEAN (Association of Southeast Asian Nations) region, gave a presentation at a National Intelligence Council-sponsored panel on the challenges of policy-relevant interdisciplinary research, and participated in a roundtable discussion on new directions in water/conflict research. Prior to the ISA meeting, he attended a brainstorming session at the Pacific Institute in Oakland involving a number of groups working on water/conflict issues.

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.
