The lead author, Yuanyuan Yang of the Institute of Geographic Sciences and Natural Resources of the Chinese Academy of Sciences, visited CIESIN in 2013‒2014 while a doctoral student in land use management at Jilin University in China. The article describes a spatially-explicit modeling framework for reconstructing historical land use change in Zhenlai County in northeastern China.
Participants on day two of the meeting on settlements, infrastructure, and population data, organized and hosted by CIESIN at Columbia's Lamont campus February 1–2.
Understanding where people live and where their buildings and other infrastructure are located is critical to improving health care and other essential services, reducing vulnerability to hazards, expanding access to markets, and supporting other aspects of sustainable development. Numerous public and private sector organizations around the world are working to produce geospatial data on human settlements, the built infrastructure, and population distribution, drawing on a growing array of data sources including satellite-based radar, night-time light sensors, and high-resolution imagery. Following up on an initial meeting held at SciDataCon 2016 in Denver last fall, CIESIN invited more than 25 experts from academia, private companies, international organizations, and development agencies to the Columbia University Lamont campus in Palisades, New York, February 1–2 to compare methods, explore opportunities to collaborate, and assess how to make data more usable for a range of applications. The group then met February 3 on the Morningside campus with more than 15 representatives of stakeholder organizations, to identify user needs and priorities from the perspective of United Nations agencies, development organizations, funders, and other interested parties.
Participants in the meeting agreed to collaborate on an intercomparison study in Nigeria, to improve understanding about the advantages and limitations of different settlement, infrastructure, and population data sets and their appropriateness for different applications. There was also strong support for efforts to better coordinate data access and documentation, improve consistency and transparency of data and methods, and share data, computing resources, and expertise. Recognition is clearly growing among users and other stakeholders of the importance of these data as an essential foundation for monitoring and decision making with respect to the Sustainable Development Goals (SDGs), and as a unique resource to enable better integration of data across boundaries, time periods, and the public and private sectors.
The meeting was supported by a Cross-Cutting Initiative grant from the Earth Institute and by the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN. Participants included experts from Facebook, Google Earth Engine, Esri, ImageCat, the European Commission's Joint Research Center, Oak Ridge National Laboratory, the U.S. Bureau of the Census, the World Bank, the WorldPop project, the Bill and Melinda Gates Foundation, the United Nations Committee of Experts on Global Geospatial Information Management, and several different universities in the United States, United Kingdom, and China.

The workshop was funded by the National Science Foundation.
When major storms or other extreme events occur, key organizations such as emergency management and utilities, transportation, and communication networks must mobilize quickly to activate and position resources and make a range of decisions to ensure public safety, reduce the severity of impacts, and improve recovery times. Representatives of a diverse set of Federal, state, and local agencies, public and private utilities, and other business groups met January 26 in Philadelphia for the second Data Driven Decision Making (D3M) workshop, held to examine how improved access to diverse earth science and socioeconomic data could help improve disaster decisionmaking in specific use cases related to flooding, power restoration, and regional situational awareness. During the meeting, CIESIN director Robert Chen gave presentations on a range of decision support tools and data sets relevant to these use cases, including the Hazards Mapper and HazPop mobile app available from the NASA Socioeconomic Data and Applications Center (SEDAC), as well as data on building footprints, critical infrastructure, impervious surfaces, and social vulnerability. CIESIN is working with StormCenter Communications, Inc. to incorporate the SEDAC Population Estimation Service into StormCenter′s GeoCollaborate tool, which provides a disaster data Daily Dashboard for the Fleet Response Working Group (FRWG). The FRWG is a public-private working group of the All Hazards Consortium (AHC), co-organizer of the D3M workshops with the ESIP Federation.
CIESIN, in collaboration with the City University of New York (CUNY) Institute for Demographic Research and the Potsdam Institute for Climate Impact Research (PIK), has begun an innovative modelling project for the World Bank that aims to develop scenarios of future population distribution taking into account climate impacts in key socioeconomic sectors. The project will contribute to the World Bank report, “Climate Change, Migration and Securing Resilience: An Evidence-Based Approach for Action,” to be published in late 2017. The work builds on existing spatial population projections that do not incorporate climate impacts. Alex de Sherbinin, associate director for science applications, is co-leading the project. He travelled to Washington DC January 25–26 to participate in the project kickoff meeting at the World Bank.
While in DC, de Sherbinin also joined food security experts for the January 26 panel, “Ending Famines, Creating Food Security, and Fostering Thriving Livelihoods in a Changing World,” sponsored by Tetra Tech and the Wilson Center Environmental Change and Security Program. Panelists offered insights on innovative initiatives to increase food security and bolster resilience to climate-related disasters in the world’s food insecurity hotspots. Comments by de Sherbinin focused on the use of geospatial data and analytics to study the factors contributing to past crises, to address crises as they unfold, and to build resilience for the future.

CIESIN director Robert Chen (left) with Talip Kilic senior economist, Development Data Group, The World Bank, at the Cape Town International Conference Center, UN World Data Forum, January 16, 2017.
The first United Nations World Data Forum brought together more than 1,000 experts on sustainable development data and monitoring from approximately 100 countries to Cape Town, South Africa, January 15–18 to consider data challenges and opportunities associated with the 2030 Agenda for Sustainable Development. In order to achieve the 17 Sustainable Development Goals (SDGs) adopted by the international community in September 2015, significant improvements are needed in the breadth, quality, and timeliness of a diverse set of socioeconomic and environmental data and indicators, not only to support monitoring of the SDGs, but also to facilitate effective sustainable development decision-making from local to global scales. With this in mind, the UN Independent Expert Advisory Group on the Data Revolution for Sustainable Development (IEAG) recommended the establishment of the World Data Forum in its 2014 report, A World That Counts. CIESIN director Robert Chen, who served as a member of the IEAG, was invited by the UN Statistics Division to join the Forum’s Programme Committee in July 2016. He coordinated more than six different sessions dealing with open data principles, technical standards and best practices, applications of geospatial and remote sensing data, and development of new data tools and services. He also gave a presentation on legal interoperability of data, based on the work of the Legal Interoperability Interest Group of the Research Data Alliance (RDA) and Committee on Data for Science and Technology (CODATA), which he co-chairs.
The Forum also served as a venue for several side events and activities. On January 19, Chen participated in the Third UN Data Innovation Lab workshop, organized by the UN World Food Programme and UN Global Pulse. He gave a presentation to mid-career staff from various UN and nongovernmental organizations (NGOs) on CIESIN′s partnership with Facebook and the World Bank in developing new high resolution settlement layer (HRSL) data, and ongoing efforts to develop a broader “data collaborative″ for georeferenced population, settlement, and infrastructure data. Chen also participated in January 15 and 19 meetings of the Global Partnership for Sustainable Development Data (GPSDD), a global network of governments, NGOs, and businesses working together to mobilize data in support of sustainable development. CIESIN is an Anchor Partner of the GPSDD and also works closely with other members such as the UN Sustainable Development Solutions Network (UNSDSN) and the Group on Earth Observations (GEO).

Building on more than 20 years of effort to improve mapping of human population, the fourth version of the Gridded Population of the World (GPWv4) data collection has been released. This new version provides scientists, applied users, and the general public with a more detailed and consistent view of the spatial distribution of population over two decades, designed to support interdisciplinary understanding and analysis of the interactions between human and environmental systems.
GPWv4 includes population estimates and projections at five-year intervals from 2000 to 2020 at a higher resolution than previous versions: 30 arc-seconds, or approximately 1 kilometer (0.6 miles) at the equator. GPWv4 reflects data from the 2010 round of national censuses, which occurred mainly between 2005 and 2014. The NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN collected and carefully matched population and boundary data for more than 13 million subnational administrative units, a 31-fold increase over version 3. Improved data were obtained for more than 100 countries including many small-island nations.
Grids of population counts and density, land area, water area, and data quality indicators are available for free download. Two different sets of population grids have been produced, one reflecting population totals reported by each country and another adjusted to national statistics developed by the United Nations (UN). Files may be downloaded for use in Geographic Information System (GIS) software or other analysis packages. The collection also includes a data set of the central point locations for subnational administrative units, for users needing tabular or vector (point) data.
In addition, SEDAC offers a range of map services and clients to visualize and access GPWv4 data, including the SEDAC Map Viewer, the Population Estimation Service, and the Hazards and Population (HazPop) mobile app for iOS devices. Several of these clients enable users to estimate the population residing within a user-defined circle or polygon, based on GPWv4 data for the year 2015.
GPWv4 is unique in characterizing population distribution based only on national census results, which enables it to be compared and combined with other types and sources of data. Other gridded population data products such as those available from the WorldPop project, the European Commission′s Joint Research Centre (JRC), and the Oak Ridge National Laboratory (ORNL) utilize additional data layers to model population distribution, which may preclude their use for some research and applications. CIESIN has been collaborating with the JRC, Facebook′s Connectivity Lab, WorldPop, and other groups to produce complementary gridded products consistent with GPWv4, such as the Global Human Settlements Population Grid (GHS-POP), the High Resolution Settlement Layer (HRSL), and the planned WorldPop global layer. Gridded population products are useful in diverse applications such as estimating population exposure and vulnerability to natural and technological hazards, determining accessibility to markets or services, and managing land, water, and ecosystem resources.
SEDAC is working to add additional gridded variables to the GPWv4 data collection, including data on age structure, gender, and urban vs. rural population, which should be available by mid-2017. GPWv4 data are made available openly at no cost under a Creative Commons Attribution 4.0 International License (CC-BY-4.0). Users are asked to register using a NASA Earthdata login when downloading data from the SEDAC site. SEDAC is one of the Distributed Active Archive Centers (DAACs) in NASA's Earth Observing System Data and Information System (EOSDIS), and has the mission to develop and operate applications that support the integration of socioeconomic and earth science data and to serve as an “Information Gateway″between the earth and social sciences.
