The latest update to the Gridded Population of the World data collection, GPW version 4.11, provides access to more than 100 interactive map layers through a Web Map Service (WMS), facilitating visualization through map tools such as the SEDAC Map Viewer. The WMS now includes 78 map layers for population estimates by age and sex categories for the year 2010, enabling users to explore potential differences in the spatial distribution of specific population subgroups. Version 4.11, available from the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN, also corrects several technical issues from the previous version, most notably re-coding missing data values.

First developed in 1994, GPW has been used widely to support research, planning, and applications on diverse topics, including energy and water management, disaster and humanitarian response, agriculture and food security, public health, transportation and communications, and urban and coastal zone planning. The recently released age and sex data expand GPW’s usefulness for mapping differential vulnerability and risk, studying urbanization and migration, assessing emergency response and public health needs, and other sustainable development applications. The data are free and downloadable from SEDAC, which also provides detailed documentation, premade maps, and interactive mapping tools. Free registration with NASA's Earthdata system is required to download data and maps.

New Project To Develop Tools for Assessing Security Implications of Environmental Stressors

March 8, 2019

CIESIN is partnering with ISciences and Case Consulting International on a new two-year project, Data ANalytics and Tools for Ecosecurity (DANTE), which is developing an open source software toolkit for systematic monitoring, forecasting, and analysis of environmental stressors and their impacts on security. Supported by the U.S. Army Engineer Research and Development Center (ERDC), DANTE is focusing on the role of environmental stressors in three key areas: international migration and refugee flows; internal migration and isolated populations; and conflict and political instability. The tools are being designed to accelerate quantitative interdisciplinary analysis of environmental stressors, taking into account demographics, economics, health, conflict, hazards, and other factors. The project aims to create a shared resource for analysts from academic, intelligence, business, and nongovernmental communities to better and more rapidly anticipate conditions that may require humanitarian assistance, efforts to reduce conflict potential, or other measures. The project represents the second phase of a Small Business Technology Transfer (STTR) award from the U.S. Army Corps of Engineers (USACE), led by CIESIN alumnus Tom Parris of ISciences. CIESIN is developing analytic use cases, providing expertise on demographic, conflict, and other data, and supporting tool development. A project kickoff meeting was held at the Lamont campus in mid January, and the project web site was launched in early March.
