Population Distribution and Change

This Webinar kicked off the cyberseminar held May 10–18, 2021, by the Population and Environment Research Network (PERN), which focused on new perspectives and innovative methodological approaches in geography, remote sensing, economics, disaster studies, and development studies, that shed light on the environmental and climatic challenges faced by global refugees. Organized by Jamon Van Den Hoek and David Wrathall, Oregon State U.; and Susana Adamo and Alex de Sherbinin, CIESIN, Columbia U., and PERN co-coordinators. PERN is a panel of The International Union for the Scientific Study of Population (IUSSP) and a sustained partner of Future Earth. Co-sponsored by GEO Human Planet, technical support by the NASA-funded Socioeconomic Data and Applications Center (SEDAC) at the Center for International Earth Science Information Network of Columbia University.

Part Two of a two-part training by NASA’s Applied Remote Sensing Training Program (ARSET), “Introduction to Population Grids and their Integration with Remote Sensing Data for Sustainable Development and Disaster Management,” held March 30 and April 6, 2021. It was organized by CIESIN research scientist Susana Adamo on behalf of NASA’s Socioeconomic Data and Applications Center (SEDAC) and the POPGRID Data Collaborative. Part Two,  “Population Grid Application Areas,” features case studies and lectures. 90-minute recording, Q and A transcript, and presentation slides are available.

Part One of a two-part training by NASA’s Applied Remote Sensing Training Program (ARSET), “Introduction to Population Grids and their Integration with Remote Sensing Data for Sustainable Development and Disaster Management,” held March 30 and April 6, 2021. It was organized by CIESIN research scientist Susana Adamo on behalf of NASA’s Socioeconomic Data and Applications Center (SEDAC) and the POPGRID Data Collaborative. Part One,“Introduction to Population Grids and Their Uses,” introduces the POPGRID Data Collaborative, the origins of gridding, and its evolution to present day application areas in health, humanitarianism, development, and disaster risk reduction. 90-minute recording, Q and A transcript, and presentation slides are available.

This PERN Webinar kicked off the cyberseminar May 18–25, 2021, focusing on analysis of the population-climate change-food security nexus using methodological tools and concepts in demography, geography, economics, systems analysis, and other related fields. It was hosted by the International Institute for Applied Systems Analysis (IIASA) and CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) and organized by IIASA, University of Minnesota, CUNY Baruch, CIESIN-Columbia University, Environmental Science for Social Change), Population Council and Asian Population Research Center, and Escola Nacional de Ciências Estatísticas-ENCE.

This presentation by SEDAC deputy manager Alex de Sherbinin describes research he has conducted either using SEDAC data or to develop SEDAC-disseminated data sets. The lecture was given to the Pennsylvania State University Department of Geography coffee hour in February 2020.

An introduction to the growing diversity of gridded data and overview of approaches, including those that utilize new sources of remote sensing data, and an introduction to the SEDAC POPGRID Viewer, which lets users easily compare data products for their specific regions of interest; under the auspices of the POPGRID Data Collaborative. Part of NASA′s EarthData Webinar Series.

This “cyberseminar” offered October 14–18, 2019, focuses on various gridded population and settlement data products and their suitability for different application areas in population-environment studies. Hosted by the Population and Environment Research Network (PERN) and organized by CIESIN and the POPGRID Data Collaborative, which is funded by the Bill and Melinda Gates Foundation. 

This brief video introduction introduces users to the companion data sets Human Built-up and Settlement Extent (HBASE) and Global Man-made Impervious Surface (GMIS), and demonstrates how to use the mapping tool to visualize the data. HBASE and GMIS were produced as a result of a collaboration between the NASA Goddard Space Flight Center and the Department of Geographical Sciences at the University of Maryland, funded through the NASA Land Cover Land Use Change Program.

An introduction to the data products and services offered by the NASA Socioeconomic Data and Applications Center (SEDAC).

This cyberseminar held February 20–27, 2018, looked at key future directions for the integration of remote sensing into social science research, building on the groundbreaking “People and Pixels” volume produced by the National Research Council in 1998. It was organized by the Population-Environment Research Network (PERN), which is hosted by SEDAC and sponsored by the International Union for the Scientific Study of Population  and Future Earth.  

How demographic shifts, evolving cultural values and beliefs, and the changing environment may interact is the focus of this Webinar to launch the “cyberseminar” hosted by the Population and Environment Research Network (PERN) May 15–19, 2017, and organized by CIESIN and the Columbia Aging Center.

This brief video is an introduction to the most recent update to the NASA SEDAC flagship gridded data product, Gridded Population of the World (GPW), which models the global distribution of human population on a continuous surface. New features of GPWv4 include more recent census data; a smaller grid size; and many more input census units.

A simple, online tool for estimating the population living in proximity to hazardous events as well as human settlements and major facilities such as dams and nuclear power plants. The Hazards Mapper displays near-real-time data on earthquakes, fires, air quality, and, for the U.S., flood and tornado warnings. Part of the monthly NASA Earthdata Webinar Series that highlights NASA EOSDIS data products and data access tools.

Gridded Population of the World (GPW) is a global, high-resolution population data collection produced by the NASA Socioeconomic Data and Applications Center (SEDAC). Part of the monthly NASA Earthdata Webinar series that showcases NASA EOSDIS data products and data access tools, this Webinar focuses on the development of GPW, improvements to this fourth version, research and policy applications, and methods.

Using the results of a climate vulnerability mapping exercise for Mali, West Africa, as an example, this video describes how SEDAC data were integrated with NASA data to produce a decision support tool for the US Agency for International Development (USAID).

This overview of integrating socioeconomic and remote sensing data to explore human interactions in the environment is part of the monthly NASA Earthdata Webinar Series that showcases NASA EOSDIS data products and data access tools. Also available via Adobe Connect.
