Population Data, Hazard Exposure, and Sustainable Repositories Addressed in Three DC Area Talks

Tue Jan 30 00:00:00 EST 2018

Greg Yetman, CIESIN associate director for Geospatial Applications, and Robert Chen, CIESIN director, gave three talks in the Washington DC area January 25–29 as part of events organized for three different U.S. government agencies. On January 25, Yetman gave an invited presentation at the MapTech GEO seminar at the U.S. Bureau of the Census in Suitland, Maryland. His presentation, “Integration and Transformation of Census Data: Modeling Population on Raster Surfaces,″ described a range of approaches to modeling population distribution utilized in different data products, including CIESIN's new Gridded Population of the World version 4.10 (GPWv4.10) data set, the High Resolution Settlement Layer (HRSL) data developed in collaboration with Facebook, and other datasets produced through collaborations with the WorldPop project and the European Commission's Joint Research Center (JRC).

On January 25-26, Chen attended a two-day workshop, “Creating and Implementing Sustainability Plans for Data Repositories,” organized by the Ecological Society of America on behalf of the U.S. National Science Foundation (NSF). The workshop, held in Alexandria, Virginia, near NSF′s new headquarters, brought together more than 30 managers of digital data repositories, data science experts, and NSF staff members to explore challenges and opportunities in increasing the long-term sustainability of valuable scientific data archives and services given changing technology, user needs, funding environments, and business models. Chen gave a plenary talk about the NASA Socioeconomic Data and Applications Center (SEDAC), which he has managed for more than two decades. The chair of the SEDAC User Working Group, Myron Gutmann of the University of Colorado, was a member of the workshop's organizing committee.

Chen returned to the Washington DC area January 29 to give a presentation as part of the PrepTalks Symposium organized by the Federal Emergency Management Agency (FEMA). The Symposium, held at George Washington University, featured eight speakers showcasing cutting-edge research and relevant experience of value to emergency managers. Chen gave the presentation, “Who's at Risk: Rapid Mapping of Potential Hazard Exposure,″ featuring a range of data and tools from SEDAC and other NASA data sources useful in emergency planning and response. The PrepTalks are recorded on video and subsequently posted to YouTube as an online resource for the emergency management community.

New Report Ranks Nations’ Environmental Performance, Reveals Trends

Air quality is the leading environmental threat to public health, according to the 2018 Environmental Performance Index (EPI) released January 23 at the annual meeting of the World Economic Forum in Davos, Switzerland. The biennial report, which ranks 180 countries on 24 performance indicators across 10 issue categories covering environmental health and ecosystem vitality, was produced by the Yale Center for Environmental Law & Policy (YCELP) and CIESIN. Switzerland is ranked first in environmental performance, followed by France, Denmark, Malta, and Sweden. In 2016, France and Sweden also made the top five.

In spite of strong scores on sanitation and air quality, the United States places only 27th in the 2018 EPI, thanks to weak performance on deforestation and greenhouse gas emissions, among other issues. This puts the United States near the back of the industrialized nations, behind France (2nd), the United Kingdom (6th), Germany (13th), Japan (20th), and Canada (25th).

Of the large emerging economies, China and India rank 120th and 177th respectively, due to pressures on the environment from high population densities and rapid economic expansion. “The strain on resources from past and current population growth, and the challenges of raising two billion people out of poverty, has meant that these countries face particular challenges,” according to co-author Alex de Sherbinin, associate director for science applications at CIESIN. “From nitrogen pollution, inadequate waste water treatment, air pollutant emissions and concentrations, China and India face severe environmental challenges.” 

In addition to rankings, the EPI identifies important environmental trends. For example, the report finds that fisheries continue to deteriorate in most countries, and air pollution—a problem largely “solved” in advanced developed countries—is still a critical problem in many developing countries, especially in India, China, and Pakistan. And some countries are failing to address critical problems. Deforestation, for example, has been a significant issue for Indonesia, Malaysia, and Cambodia for the past five years, reflecting broad policy failures, according to the report.

NASA Showcases Research Using Earth Science Data

Fri Jan 05 00:00:00 EST 2018

NASA has recently released the 2017 edition of Sensing Our Planet, free in print or for download at the Earthdata Web site. The publication highlights the use of earth science data in a range of scientific research areas, from hazard prediction to public health to water resource management. One of this year′s articles, “Zika Zone,” focuses on mapping the spread of the Zika virus. Researchers Moritz Kramer from the Harvard Medical School and Janey Messina from the University of Oxford combined environmental data about the Zika virus—for example, preferred habitat, temperature and rainfall requirements, and need for stagnant water to lay eggs in and heavily populated urban environments—with population data to create maps showing environmental suitability for the transmission of the virus. Data sources included the Gridded Population of the World (GPW) data collection from the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN and a vegetation index based on Moderate Resolution Imaging Spectroradiometer (MODIS) data from the Land Processes Distributed Active Archive Center (LP DAAC). Mapping the transmission in this way let the scientists estimate the number of people globally at risk—more than two billion—and anticipate areas of potential Zika outbreaks, helping to inform public health decisions. GPW data were also used together with gravity and radar data and land surface models from several other DAACs to assess groundwater resources in Mexico, as described in the article, “Closed Season.″

Sensing Our Planet highlights data from the twelve DAACs of the NASA Earth Observing Data and Information System (EOSDIS). The publication has been produced since 1994 by the Snow and Ice DAAC at the National Snow and Ice Data Center at the University of Colorado Boulder.

Changing Mangroves, Future Heat Stress, and Data Stewardship Addressed in New Publications

Thu Jan 04 00:00:00 EST 2018

CIESIN staff and colleagues have capped the end of 2017 and launched 2018 with several new publications on a range of topics. Senior research associate Pinki Mondal is a lead author of a study on long-term changes in mangrove extent in Sierra Leone. The West African country lost 25% of its mangroves between 1990 and 2016, the span of the analysis. Using remote sensing data, the study focuses on four estuaries—Scarcies, Sierra Leone, Yawri Bay, and Sherbro—to provide insight into mangrove management strategies that can support local livelihoods. Sylwia Trzaska, associate research scientist, and Alex de Sherbinin, associate director for Science Applications, are co-authors. The work was funded by the U.S. Agency for International Development (USAID) and conducted in collaboration with Tetra Tech. The paper appears in the journal Sensors, as part of a special issue, “Remote Sensing of Mangrove Ecosystems,” edited by Chandra Giri, an alumnus of CIESIN now with the U.S. Environmental Protection Agency.

Alex de Sherbinin is also co-author of a new global study of heat waves appearing in Environmental Research Letters, among the first research to include humidity as a critical factor in assessing heat stress impacts. The lead authors are Ethan Coffel and Radley Horton of Columbia University and the NASA Goddard Institute for Space Studies (GISS). The study utilizes data available from the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN—Global Population Projection Grids Based on SSPs, v1 (2010 – 2100)—to quantify the number of people who may be exposed to extreme heat stress in the latter half of this century under different scenarios of development (Shared Socioeconomic Pathways, or SSPs).

Senior digital archivist Robert Downs has three new publications on various data management topics. He authored the chapter, “Enabling the Reuse of Geospatial Information,” in the book, GeoValue: The Socioeconomic Value of Geospatial Information, edited by Jamie B. Kruse, Joep Crompvoets, and Francoise Pearlman and published in November 2017 by CRC Press. He is also a co-author, with Devan Ray Donaldson, Ingrid Dillo, and Sarah Ramdeen, of a peer-reviewed article in the International Journal of Digital Curation on the perceived value of acquiring “data seals of approval,” an international standard for trusted digital repositories. Finally, he has authored the conference paper, “Implementing the Group on Earth Observations Data Management Principles: Lessons from a Scientific Data Center,” in The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences. This was based on his presentation at the 37th International Symposium on Remote Sensing of Environment in Tshwane, South Africa in May 2017 about how the emerging set of data management principles developed by GEO applies to interdisciplinary data management at SEDAC.
