Future Population Scenario Data and Global Development Potential Indices Released
April 16, 2020The NASA Socioeconomic Data and Applications Center (SEDAC) managed by CIESIN has released several new datasets valuable in assessing future global energy development and land use and in characterizing potential long-term future population distribution in the context of climate change.
One dataset, Global One-Eighth Degree Population Base Year and Projection Grids Based on the SSPs, was developed by Bryan Jones of the City University of New York and Brian O’Neill of the University of Denver. The dataset consists of global urban, rural, and total population data for the base year 2000, and population projections at ten-year intervals for 2010-2100 at a resolution of one-eighth degree (7.5 arc-minutes). These are consistent both quantitatively and qualitatively with the Shared Socioeconomic Pathways (SSPs) that were developed in support of the Intergovernmental Panel on Climate Change (IPCC) assessments. A second dataset, Global 1-km Downscaled Population Base Year and Projection Grids Based on the SSPs, provides a downscaled version of the first dataset, at 1-km resolution (about 30 arc-seconds). This dataset was developed by Jing Gao of the National Center for Atmospheric Research (NCAR). Spatial demographic scenario data are key inputs for the analysis of future land use, energy use, and emission patterns together with potential future climate change impacts, vulnerability, and adaptation.
A third dataset, Global Development Potential Indices (DPI), was developed by James Oakleaf of The Nature Conservancy, and colleagues. This dataset ranks global land suitability in the sectors of renewable energy, fossil fuels, mining, and agriculture, to aid in setting priorities for development and conservation efforts. Each sector-based DPI is a 1-km spatially-explicit, global land suitability map that has been validated using locations of current and planned development.
SEDAC is one of NASA′s Distributed Active Archive Centers (DAACs) in the NASA Earth Observing System Data and Information System. SEDAC seeks to improve access to and use of key socioeconomic and interdisciplinary data that are or can be integrated with remote sensing data. SEDAC datasets have been cited in more than 5,000 different scientific publications during the past 20 years.

New Map Viewer Shows Population Characteristics in Relation to Reported COVID-19 Cases
April 10, 2020A new mapping tool shows the density of population in relationship to reported coronavirus disease (COVID-19) cases at national and sub-national levels, and permits users to obtain custom estimates of the number of people by age and sex living in an area of interest, including areas not currently reporting large numbers of cases.
Developed by the NASA Socioeconomic Data and Applications Center (SEDAC), the SEDAC Global COVID-19 Viewer: Population Estimates by Age Group and Sex lets users quickly access relevant population information without having to download and analyze large amounts of spatial population data. The Viewer’s unique capability is that it allows users to obtain population estimates for specific age and sex categories for any area, such as a metropolitan region that cuts across multiple jurisdictions or countries. The Viewer displays age and sex structure charts and pyramids in response to a user-drawn circle or polygon. Data on COVID-19 cases from the Johns Hopkins University are updated multiple times per day.
The SEDAC Global COVID-19 Viewer is meant for researchers, educators, and policymakers who are interested in visualizing key population characteristics such as high concentrations of elderly individuals in urban or rural areas that are, or may become, affected by the COVID-19 pandemic. The Viewer may be especially helpful for regional analyses or for countries with limited access to spatial population data. The underlying population data are from SEDAC’s Gridded Population of the World (GPW) Basic Demographic Characteristics, v4.11, for the year 2010, with estimates to 2020. The COVID-19 data are from Johns Hopkins University & Medicine Coronavirus Resource Center. SEDAC is one of the NASA Distributed Active Archive Centers (DAACs) and is operated by the Center for International Earth Science Information Network (CIESIN) of the Earth Institute at Columbia University.
