Environmental Sustainability Indicators and Trends

CIESIN scientists remain active in a number of different scientific communities, despite travel restrictions due to the COVID-19 pandemic. On April 27, at the virtual meeting of the European Geophysical Union, Martin Juckes, co-manager of the Intergovernmental Panel on Climate Change (IPCC) Data Distribution Center (DDC), presented a lightning presentation and poster paper, “IPCC Data Distribution Centre: FAIR Data from Climate Research to Mitigation Policy.” Robert Chen and information scientist Xiaoshi Xing were co-authors. CIESIN is one of four organizations that jointly operate DDC; the other three are based in the UK, Germany, and Spain. The IPCC DDC provides access to key data sets used in IPCC assessments and reports. Also participating was Robert Downs, CIESIN senior digital archivist, who co-authored the presentation, “Towards Developing Community Guidelines for Sharing and Reusing Quality Information of Earth Science Datasets,” given by Carlo Lacagnina, Barcelona Supercomputing Centre.

Senior digital archivist Robert Downs participated virtually in the Research Data Alliance (RDA) 17th Plenary Meeting (RDA P17) April 20–23 and the 16th International Digital Curation Conference (IDCC21) on April 19, both coordinated from Edinburgh, Scotland. During RDA P17, Downs presented the poster, “Peer Review of Open Research Data: The Approach of a Scientific Data Center.” He also chaired the joint session, “Collaborating to Improve Platforms and Share Resources among Open Data Repositories,” where he presented, “Improving Repositories through Collaboration.”  At the IDCC21, Downs gave the presentation, “Documentation to Foster Sharing and Use of Open Earth Science Data: Quality Information,” co-authored with Ge Peng of NASA’s Marshall Space Flight Center, David Moroni of NASA’s Jet Propulsion Laboratory, Hampapuram Ramapriyan of Science Systems and Applications, Inc., and Yaxing Wei of Oak Ridge National Laboratory. 

As part of the International Research Institute for Climate and Society (IRI) seminar on April 20, CIESIN postdoctoral research scientist Carolynne Hultquist gave the presentation, “Bringing Vulnerable Populations into the Flood Risk Equation.” Two graduate student interns also participated: Raychell Velez, who is working toward her MS in geographic information systems (GIS) at Lehman College of the City University of New York; and Colleen Neely, an MPA student in environmental science and policy at Columbia’s School of International and Public Affairs (SIPA). Hultquist gave an overview of relevant data and services from the NASA Socioeconomic Data and Applications Center (SEDAC) and described ongoing efforts to improve vulnerability data for flood risk assessment. Velez presented work supported by SEDAC to develop high resolution data on building exposure to floods using artificial intelligence (AI) approaches. Neely, an Earth Institute intern with Hultquist and IRI scientist Andrew Kruczkiewicz, discussed work on a high resolution flood vulnerability index for Houston, Texas, designed to support more equitable flood mitigation efforts.

The Joint Research Centre (JRC) of the European Commission has released the 2020 edition of the Atlas of the Human Planet, focused on open geoinformation for research, policy, and action, under the auspices of the Human Planet Initiative of the Group on Earth Observations (GEO). This year′s Atlas features more than 30 applications of the georeferenced human settlement and population data in four thematic areas: disaster risk management, urbanization, development, and environment and sustainability. Two of the applications showcased were developed by CIESIN: the Global COVID-19 Viewer operated by the NASA Socioeconomic Data and Applications Center (SEDAC), in “Mapping the COVID-19 Pandemic and Potential Risk Factors,″ and a summary of an update to a 2007 data set available from SEDAC, in “New Estimates of Global Population and Land in the Low Elevation Coastal Zone Using GHSL-based Data Sets.″ The first showcase was prepared by CIESIN director Robert Chen, GIS programmer Kytt MacManus, and associate director for Science Applications Alex de Sherbinin. The second was authored by MacManus, former SEDAC project scientist Deborah Balk of Baruch College, staff associate Hasim Engin, UK demographer Gordon McGranahan, former research staff assistant Rya Inman, and intern Alexandra Hayes.

The JRC organized a virtual launch event January 21 that drew more than 90 participants. The event included 4 short presentations on selected applications, including the Global COVID-19 Viewer example, described by Chen. The Viewer, developed and enhanced in 2020, helps users visualize a range of data on COVID-19 cases and mortality in relationship to spatial data on demographic and environmental factors that may affect exposure and vulnerability, such as age structure, degree of urbanization, air quality, and elevation. Chen and Martino Pesaresi of the JRC are co-leaders of the GEO Human Planet Initiative.

Due to the ongoing pandemic, many international conferences have shifted to online, virtual platforms in 2020, opening up opportunities for CIESIN staff to interact remotely with new communities and showcase recent work and new resources. For example, associate director for Science Applications Alex de Sherbinin recently gave a remote keynote address, “Groundswell Model Results for South Asia,” November 25 at the International Conference on Building Resilient and Sustainable Societies, organized by Jamia Millia Islamia University in New Delhi. The address discussed ongoing work with the World Bank to model how climate impacts may induce migration out to 2050. He and research scientist Susana Adamo also participated in the virtual meeting of the Platform for Disaster Displacement’s Data and Knowledge Working Group November 24, where they gave the respective presentations, “Novel and Big Data Approaches to Identifying Disaster Displacement,” and “Migration, the COVID-19 Pandemic, and Climate in Central America’s Northern Triangle.”

During the International CODATA FAIR Convergence Symposium 2020 held virtually November 27–December 4, CIESIN director Robert Chen presented in a panel session, “Synergies between Citizen Science Data and the UN Sustainable Development Goal (SDG) Indicators,” organized by Dilek Fraisl of the International Institute for Applied Systems Analysis (IIASA) in Austria. Chen then led a breakout group within this session. Alex de Sherbinin also contributed to the session, “Citizen Science in Africa for the SDGs,” giving closing remarks. The Symposium was organized by the Committee on Data (CODATA) of the International Science Council and the GO FAIR initiative.

On December 1 Chen gave a short presentation, “Open Data Sharing Across the Disaster Lifecycle," in the community session, "A Call to Action for Resilience: Moving from Research to Practice,” held as part of the World Bank’s 2020 Understanding Risk Forum (UR2020) December 1–3. The session was organized by Charles Huyck of ImageCat, Inc. and Shanna McClain of NASA. Chen highlighted the importance of open data access and reuse throughout the disaster management lifecycle, not just in the immediate aftermath of an extreme event.

Professor Stefan Leyk of the University of Colorado organized and led a virtual workshop November 30, “Gridded Population Data for the Sustainable Development Goals,” for experts from Colombia's National Administrative Department of Statistics (DANE) and Paraguay's General Directorate of Statistics, Surveys, and Censuses (DGEEC). The workshop provided an overview of the development and sources of gridded population data, hands-on technical training in working with selected data, and a forum for obtaining feedback on user needs. CIESIN Director Robert Chen gave introductory remarks during the opening session, and in the final session research scientist Susana Adamo provided an update in Spanish on progress and plans for the fifth version of the Gridded Population of the World (GPW) data set. Associate director for Science Applications Alex de Sherbinin, associate director for Geospatial Applications Greg Yetman, and research staff assistant Juan Martinez also attended.

The workshop was organized by Leyk and Maryam Rabiee of the Thematic Research Network on Data and Statistics (TReNDS) of the United Nations Sustainable Development Solutions Network (SDSN), under the auspices of the POPGRID Data Collaborative. Funding for the workshop was provided by Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH. POPGRID is an initiative launched by CIESIN in 2017 to bring together both developers and users of global georeferenced population data in support of development applications. POPGRID activities and resources are supported in part by the Bill & Melinda Gates Foundation and the NASA Socioeconomic Data and Applications Center (SEDAC). Leyk is also a member of SEDAC′s User Working Group.

The 2020 United Nations (UN) World Data Forum was held virtually October 19–21, in place of a physical meeting in Bern, Switzerland, that has been postponed to 2021. The Forum serves as a platform for intensifying cooperation on sustainable development data across a diverse set of communities, under the auspices of the UN Statistical Commission.

Several CIESIN staff participated actively in the Forum. On October 20, Sandra Baptista, senior research associate, and Andrea Jordan, special assistant to the deputy director, both representing the Geo-Referenced Infrastructure and Demographic Data for Development (GRID3) program, co-organized the live panel, “Use of Geospatial Data to Support COVID-19 Response,” with Colombia’s National Administrative Department of Statistics (DANE). The panel was moderated by Io Blair-Freese of the Bill & Melinda Gates Foundation and included two partners in the GRID3 program: Prince Clem Ikanade Agba, minister of state for budget and national planning of the Federal Republic of Nigeria and co-chair of GRID3′s Nigeria national steering committee; and David Moinina Sengeh, minister of basic and senior secondary education and chief innovation officer for the Government of Sierra Leone.

The Forum also included a number of pre-recorded sessions. NASA, UN-Habitat, the European Space Agency, and the Group on Earth Observations (GEO) organized a session on the use of Earth observations to make cities inclusive, safe, resilient, and sustainable. CIESIN Director Robert Chen co-authored a short presentation with Thomas Kemper of the European Commission′s Joint Research Centre on behalf of the GEO Human Planet Initiative, which he co-leads. They also participated in a pre-recorded question-and-answer session.

Recordings of Forum sessions are now available online. The UN World Data Forum was originally established in response to a key recommendation in the 2014 report, “A World that Counts: Mobilising the Data Revolution for Sustainable Development,″ prepared by the UN Secretary-General′s Independent Expert Advisory Group on a Data Revolution for Sustainable Development.

CIESIN has developed and released several new data sets recently. Now available from the NASA Socioeconomic Data and Applications Center (SEDAC) is the Food Insecurity Hotspots data set, which consists of gridded data identifying the level of intensity and frequency of food insecurity over ten years between 2009 and 2019, as well as hotspots of consecutive food insecurity events. The data set covers five regions: Central America and the Caribbean, Central Asia, East Africa, Southern Africa, and West Africa. The grids are at 250 meter (~7.2 arc-seconds) resolution and are based on subnational food security analyses for these regions provided by the Famine Early Warning Systems Network (FEWS NET). FEWS NET was established in 1985 by the U.S. Agency for International Development (USAID).

As part of the Geo-Referenced Infrastructure and Demographic Data for Development (GRID3) program managed by CIESIN, data on operational settlement points and/or boundaries, health facilities, and points of interests have been released for Zambia and the Democratic Republic of the Congo. Settlement extent data are now available for 41 African countries, created from Digitize Africa building footprints powered by Maxar. GRID3 has expedited settlement extent mapping to support countries in their COVID-19 response efforts. The data are broadly intended to support country decision-making in public health and education.

Alex de Sherbinin, associate director for Science Applications, is guest editor of a special Issue of the journal Sustainability on climate risk and vulnerability mapping, with co-editor Stefan Kienberger of the University of Salzburg. He is also a co-author of one of the papers in the special issue, on using flood disaster data to validate components of social vulnerability to floods. The paper’s lead author is Earth Institute Fellow Beth Tellman.

The article, “Still in Need of Norms: The State of the Data in Citizen Science,″ has been published in the journal Citizen Science: Theory and Practice. Anne Bowser of the Wilson Center is lead author, and de Sherbinin is a co-author. The article is a major output of the CODATA-World Data System (WDS) Task Group on Citizen Science and the Validation, Curation, and Management of Crowdsourced Data, which de Sherbinin co-chaired in 2016-2018.

Senior digital archivist Robert Downs is a co-author of the report, “Laying the Groundwork for Developing International Community Guidelines to Effectively Share and Reuse Digital Data Quality Information—Case Statement, Workshop Summary Report, and Path Forward,” published in Open Science Foundation (OSF) Preprints.

A new report from the Thematic Research Network on Data and Statistics (TReNDS) of the United Nations Sustainable Development Solutions Network (SDSN) provides guidance on the use of gridded population datasets from the POPGRID Data Collaborative. The report, Leaving No One Off the Map: A Guide for Gridded Population Data for Sustainable Development, reviews population data products from POPGRID members, including CIESIN, Esri, Oak Ridge National Laboratory, and the WorldPop Project, among others. The report was written by Hayden Dahmm and Maryam Rabiee, with input from Jessica Espey, all of SDSN TReNDS. CIESIN research scientist Susana Adamo, associate director for Science Applications Alex de Sherbinin, and CIESIN director Robert Chen also contributed to the report, along with other POPGRID participants and CIESIN staff members. POPGRID was launched in 2017 through an Earth Institute seed grant led by Chen and is supported in part by the Bill and Melinda Gates Foundation and the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN.

On May 18 a live virtual debate hosted and moderated by SciDev.net and SDSN TReNDS featured panelist Alex de Sherbinin; Jessica Espey, TReNDS director; Andrea Gaughan of the University of Louisville and contributor to the WorldPop Project; and Idris Jega, assistant director with the Strategic Space Applications Department at Nigeria‘s National Space Research and Development Agency. Jega is also a member of the Nigeria secretariat for the GRID3 program managed by CIESIN. The panel discussed the importance of gridded population data and their utility in helping to achieve the Sustainable Development Goals (SDGs) established in 2015 by the United Nations.

The 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.

Associate director for Science Applications Alex de Sherbinin is a co-author of the open access article, “A Systematic Review of Coastal Vulnerability Mapping,” appearing in the journal Sustainability. The paper, by Anamaria Bukvic of Virginia Polytechnic Institute and State University, Guillaume Rohat of the University of Geneva, Alex Apotsos of Williams College, and de Sherbinin, evaluates the state of coastal vulnerability assessment mapping efforts and recommends improvements in methodological rigor, policy relevance, and alignment with other vulnerability assessment paradigms. The paper stems from previous work supported by the National Socio-Environmental Synthesis Center (SESYNC) under funding received from the National Science Foundation. The paper is dedicated to the memory of second author Rohat, who passed away unexpectedly in October 2019.

Senior digital archivist Robert Downs is also co-author of the open access paper, “Risk Assessment for Scientific Data,” published in the CODATA Data Science Journal. Authors of the paper are Matthew Mayernik of the National Center for Atmospheric Research; Kelsey Breseman of the Environmental Data & Governance Initiative (EDGI); Downs; Ruth Duerr of the Ronan Institute for Independent Scholarship; Alexis Garretson of George Mason University; Chung-Yi (Sophie) Hou of the Ronin Institute; EDGI; and the Earth Science Information Partners (ESIP) Data Stewardship Committee. The paper presents an analysis of data risk factors that scientific data collections may face, together with a data risk assessment matrix to support risk assessment and mitigation efforts.

The POPGRID Data Collaborative, an initiative launched by CIESIN in 2017 to improve the quality, access, and use of global-scale spatial data on human population, settlements, and infrastructure, has recently updated its Web site and announced an international Webinar to be held February 4 in collaboration with Geospatial World.

The POPGRID Web site helps users learn about the many different gridded population data sets now available, providing detailed background information and documentation, and direct links to the data and data sources. In addition, the POPGRID Viewer lets users easily compare different data products for their specific regions of interest. The updated site now includes links to recent publications and recorded Webinars about gridded population data, together with updated information from the data providers. POPGRID is collaboratively managed by CIESIN, the Thematic Research Network on Data and Statistics (TReNDS) of the United Nations Sustainable Development Solutions Network, and the Global Partnership for Sustainable Development Data, and is supported by the Bill & Melinda Gates Foundation and NASA. More than 20 different groups from both the public and private sectors are active in the POPGRID Data Collaborative. The POPGRID Viewer was developed by the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN.

On February 4, CIESIN director Robert Chen and Maryam Rabiee of TReNDS presented the Webinar, “Leaving No One Off the Map: Gridded Population Data for Decision Making,″ in coordination with Geospatial World. It attracted 150 participants from around the world. The Webinar focused on how gridded population data can help decision makers and other applied users improve efforts to achieve the Sustainable Development Goals (SDGs) adopted by the international community in 2015, and in particular to help reach those who might otherwise be left behind. Recent advances in mapping make it possible to better determine the location and characteristics of human settlements and households, allowing for more effective and efficient assistance, e.g., for vaccination campaigns, development assistance, and humanitarian relief. However, the proliferation of different data sets utilizing different methods and sources may confuse users about which data sets are the most appropriate to use in different situations. The Webinar discussed ongoing efforts by the POPGRID Data Collaborative to address this issue, and ways in which the geospatial community can both benefit from, and participate in, POPGRID activities. A recording is available here.

The largest international Earth and space science conference in the world, the annual American Geophysical Union (AGU) fall meeting, brought more than 25,000 scientists and other experts to San Francisco December 9–13.

TReNDS provides an important avenue for facilitating involvement and knowledge sharing by the global academic community in addressing sustainable development data challenges.

Both the Forum and the TReNDS meeting were hosted by the UAE’s Federal Competitiveness and Statistics Agency (FCSA). The First World Data Forum was held in January 2017 in Cape Town, South Africa; the next Forum is expected to be held October 18–21, 2020, in Bern, Switzerland. Summaries of the discussions at the Forums have been provided by the Earth Negotiations Bulletin.

Geographers from across the U.S. and the world met in New Orleans April 10–14 at the annual meeting of the American Association of Geographers (AAG), to present and discuss recent and ongoing research on diverse geographic topics, including hazards, urbanization, public engagement. Several sessions on human settlement and population mapping were organized, including two on high-resolution population modeling and a session on advancements in detecting and projecting population and the footprint of human settlements. CIESIN director Robert Chen gave a presentation at the latter session on the ongoing efforts of the POPGRID Data Collective to advance the use and impact of geospatial settlement, infrastructure, and population data in sustainable development and other applications. Greg Yetman, associate director for Geospatial Applications, discussed mapping green infrastructure and impervious surfaces in New York City, in a session, “Making the City Green.″ His presentation was co-authored with John Squires, senior research staff assistant, and was based on work supported by the U.S. National Science Foundation as part of the project, Developing High Performance Green Infrastructure Systems to Sustain Coastal Cities, led by Patricia Culligan of the Department of Civil Engineering and Engineering Mechanics and the Urban Design Lab. POPGRID activities are supported in part by the Bill & Melinda Gates Foundation and by the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN.

A new project, “Geo-referenced Infrastructure and Demographic Data for Development (GRID3),” was launched at a side event of the 49th session of the United Nations Statistical Commission held March 7 in New York City. The side event featured a panel presentation on project objectives and applications by representatives of core GRID3 partners, including Marc Levy, CIESIN deputy director; Linus Bengtsson, executive director and co-founder of Flowminder; Rachel Snow, chief, Population and Development Branch, United Nations Population Fund (UNFPA); and Tapiwa Jhamba, technical advisor, also of UNFPA. Joining the core partners as a panelist was Homere Ngoma Ngoma, census coordinator at the Central Bureau of the Census, National Statistics Institute, Democratic Republic of the Congo (DRC), who made a presentation on the 2019 DRC census and the potential impact of GRID3 involvement. Also attending were CIESIN senior research staff assistants Olena Borkovska and Kira Topik, and project coordinator Kevin Tschirhart. A lively question-and- answer session followed the presentations.

GRID3 is facilitating the collection, analysis, integration, dissemination, and utilization of high-resolution population, infrastructure, and other reference data in support of national sectoral development priorities, humanitarian efforts, health, and sustainable development goals (SDGs). The project aims to increase developing countries’ capabilities for mapping population distribution as a way of ensuring that everyone, especially the most vulnerable, is counted, refining development priorities and extending and improving the scope and efficacy of countries’ development efforts. The project is funded by the Bill & Melinda Gates Foundation and the United Kingdom′s Department for International Development (DFID).
