New Data Sets Document Urban Population Change Over Six Millennia and the Recent Human Footprint

Mon Oct 15 00:00:00 EDT 2018

Humans have altered the Earth′s land surface over many millennia, with the most dramatic changes coming in recent decades as population has grown, urban areas have spread, and technology and environmental changes have transformed ecosystems worldwide. A unique data set, Historical Urban Population, v1 (3700 BC‒AD 2000), is now available that documents the location and size of urban populations over the past 6,000 years. Developed by Meredith Reba of Yale University, Femke Reitsma of the University of Canterbury in New Zealand, and Karen Seto of Yale, the data set was assembled by digitizing, transcribing, and geocoding historical, archaeological, and census-based urban population records from diverse sources. The data set illuminates long-term urbanization trends and patterns, supporting better understanding of both current and future urbanization trends and associated implications for population, land use and land cover change, and environment.

In 2002, the first Human Footprint/Last of the Wild (HF/LOW) data sets, developed by the Wildlife Conservation Society in collaboration with CIESIN, were released through the NASA Socioeconomic Data and Applications Center (SEDAC). Version 1 mapped human influence on the planet′s land surface drawing on spatial data for population, settlements, roads, railroads, agriculture, power infrastructure, and other factors, mostly dating from the early 1990s. The least influenced or “wild” areas in each biome were identfied in the LOW data set. In 2005, version 2 of the data set was released, with more complete and consistent data from about the year 2000.

Version 3 of the Human Footprint data sets, providing snapshots of human influence circa 1993 and 2009, is now available through SEDAC. The Human Footprint, 2018 Release (1993) and Human Footprint, 2018 Release (2009) were developed by an international team of scientists led by Oscar Venter of the University of Northern British Columbia. The team included Eric Sanderson of the Wildlife Conservation Society, who led development of the first HF/LOW data sets, and CIESIN deputy director Marc Levy. The new HF data sets are based on a modified methodology and more recent data inputs on built-up environments, population density, electric power infrastructure, crop lands, pasture lands, roads, railways, and navigable waterways. The data are available at a spatial resolution of about 1 kilometer and may be downloaded as a GeoTIFF file or accessed through open online web map services.

Enhanced Population Mapping Tools Deliver Customized Demographic Estimates

Fri Oct 05 00:00:00 EDT 2018

The Population Estimation Service (PES) and associated Population Estimator mapping tool have recently been updated to provide users with the ability to visualize changes in total population over multiple decades together with basic demographic characteristics (age and sex) in the year 2010, for a user-defined geographic region. Version 3 of the Population Estimator enables users to draw a circle or polygon on a world map, which then produces a graph of estimated population for the years 2000, 2005, 2010, and 2015, and a projection to the year 2020. The Population Estimator also provides a “population pyramid” for the year 2010, with estimated population counts by five-year age groups for males and females. Users may save the graphs in selected image formats and download the tabular data for further analysis.

These detailed demographic estimates may be highly useful to those interested in assessing how different areas of the world vary in terms of their population growth between 2000 and 2020, and in comparing the relative shape and structure of their population pyramids. The data may be used to estimate important demographic characteristics such as the sex ratio, median age, dependency ratios, and the number of women of child-bearing age. Estimated totals for specific age  groups (children under five or the elderly) may be useful as indicators of potential vulnerability to natural, technological, or human health hazards or of the type and level of specific social or health services needed in an area. However, it should be noted that in many parts of the world, censuses have been infrequent, and detailed demographic data at subnational levels are not always available; therefore, population and age-sex data for small subnational areas should be used with caution and the documentation should be consulted.

Behind the scenes, the PESv3 draws on the latest version of the Gridded Population of the World data collection (GPWv4.10), which is based on the most current national census data available. Through open web service protocols, any client developer can send queries to the PES to obtain customized estimates for a specified circle or polygon. Links to the service descriptions are available online. Further information is available through SEDAC User Services. PESv3 and the Population Estimator are supported by the NASA Socioeconomic Data and Applications Center (SEDAC), operated by CIESIN as part of the NASA Earth Observing System Data and Information System (EOSDIS).

Indicator Data for Environmental Performance and Health Updated

Mon Sep 24 00:00:00 EDT 2018

The NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN has released updates to two national-level, policy-focused indicator data collections. The 2018 Environmental Performance Index (EPI), produced every two years by a research team from the Yale Center for Environmental Law and Policy and CIESIN, ranks country performance on high-priority environmental issues in two broad policy areas: protection of human health from environmental harm and protection of ecosystems. The 2018 EPI evaluated 180 countries on 24 performance indicators across 10 issue categories covering environmental health and ecosystem vitality.

The Natural Resource Protection and Child Health Indicators, 2017 Release (2010 – 2017), is the most recent update to a data set first released in 2010. It was created by CIESIN in support of the U.S. Millennium Challenge Corporation (MCC), which has established selection criteria for the eligibility of countries for foreign assistance. This release includes a consistent time series of Natural Resource Protection (NRPI) scores for 234 countries from 2013 to 2017 and Child Health Indicator (CHI) scores for 199 countries from 2010 to 2017.

Both data sets are available for free download from the SEDAC web site. An Earthdata Login, available for free, is required to access the data.

Two different international organizations focused on data sharing and management organized working meetings in Europe June 11–15. In Geneva, Switzerland, the Group on Earth Observations (GEO) held its 2018 Symposium June 11‒12 at the headquarters of the World Meteorological Organization. CIESIN director Robert Chen served as co-chair and co-moderator for a plenary session on GEO challenges and opportunities for data sharing and management. During the session, senior digital archivist Robert Downs gave a short presentation on data quality control and documentation efforts under way at the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN. Chen then co-chaired a June 13 meeting of the GEO Data Sharing Working Group (DSWG), which has led GEO′s efforts to promote open data sharing for more than a decade. The meeting included discussions with the incoming GEO Secretariat Director, Gilberto Câmara. GEO is an international partnership of more than 100 national governments and in excess of 100 Participating Organizations working to ensure that coordinated, comprehensive, and sustained Earth observations inform decisions and actions that benefit humanity.

The Research Data Alliance (RDA) held its 9th Working Group (WG) and Interest Group (IG) Collaboration Meeting June 13‒15 in Vienna, Austria. The meeting brought together RDA WG and IG chairs and co-chairs to identify collaborative opportunities and develop specific plans. Downs serves as a co-chair for the RDA Repository Platforms for Research Data IG and for the RDA Data Versioning WG, and represented both groups at the meeting. RDA is a community-driven international organization aiming to build the social and technical infrastructure to enable open sharing of data. RDA currently has more than 7,000 members from 137 countries.


Links between Climate and Conflict Not Overstated, Says CIESIN′s Marc Levy

Fri Jun 08 00:00:00 EDT 2018

In correspondence published in the journal Nature Climate Change, deputy director Marc Levy argues that sampling bias does not exaggerate climate-conflict claims. He addresses an article published earlier in the same journal claiming that literature on climate-conflict links is biased with respect to countries covered, and that this bias contributes to a misunderstanding of the links. Levy notes that although the literature is uneven with respect to countries, that doesn't mean each study is biased and therefore there′s no reason to infer exaggeration. For example, the two studies that the authors cite as evidence that bias exaggerates climate-conflict links in fact conclude from their “biased” work that the strength of climate-conflict links are zero or low. Levy concludes that although the literature would benefit from broader case selection, there is no reason to suspect that the current literature exaggerates the role of climate in conflict.

Levy leads the Environment and Security Program at CIESIN. Most recently he was one of the core faculty members for the Massive Open Online Course (MOOC), “Environmental Security and Sustaining Peace,” which attracted nearly 10,000 enrollees from about 150 countries.

Workshop on Climate Adaptation Planning Held in Ghana

Mon Jun 04 00:00:00 EDT 2018

Participants in a climate information for adaptation planning workshop

Representatives from six West African countries―Cote d’Ivoire, Ghana, Guinea, Liberia, Sierra Leone, and Togo―participated in the workshop, “Climate Information for Adaptation Planning,” held May 29‒June 1 in Ada, Ghana. Sylwia Trzaska, CIESIN associate research scientist, and Emilie Schnarr, research associate, facilitated the workshop, which was sponsored by the West Africa Biodiversity and Climate Change (WA BiCC) project of the U.S. Agency for International Development. The purpose of the workshop was to provide participants, some of whom are involved in the National Adaptation Plan (NAP) process of the United Nations Framework Convention on Climate Change (UNFCCC), with information to critically evaluate climate analyses, identify gaps in climate information, develop solutions to address these gaps, and support stakeholder collaboration within and between countries. Participant feedback was positive, especially with respect to learning how to evaluate climate information in the context of planning climate adaptation initiatives. Workshop participants also discussed the need for an online platform for the six countries to exchange ideas and resources, and enhance climate information data sharing, lessons learned, and accomplishments. CIESIN is one of the implementing partners of the WA BiCC project, which is led by Tetra Tech.


‘Groundswell’: Modeling Climate Change Impacts on Internal Migration

Fri Jun 01 00:00:00 EDT 2018

Chart showing projected number of climate migrants in Sub-Saharan Afria, South Asia, and Latin America under three scenarios, by 2060

Alex de Sherbinin, CIESIN associate director for Science Applications, and Susana Adamo, research scientist, played key roles in preparing the recent World Bank report, Groundswell: Preparing for Internal Climate Migration. The report assesses the potential future impacts of climate change on migration within countries in Latin America, South Asia, and sub-Saharan Africa. It was developed by the World Bank Climate Change Group in partnership with CIESIN, the City University of New York (CUNY) Institute for Demographic Research, and the Potsdam Institute for Climate Impact Research.

The Groundswell report focuses on the influence of medium- to long-term climate change impacts, including changes in crop production and water availability and sea level rise. Internal migration is inferred from projected changes in population distribution. This novel modeling approach identifies potential “hotspots” of climate-induced in- and out-migration in three regions―Mexico and Central America, East Africa, and South Asia—and also provides a basis for estimating the total number of migrants. Main messages from the report are: 

• In a worst-case scenario, by 2050 there could be as many as 143 million internal climate migrants in the three regions.

• Governments should be aware of the potential for climate impacts to affect population distributions within their countries, and proactively plan in ways that facilitate local adaptation, while assisting those who need to move because of worsening conditions.

• Migration can be seen as a positive adaptation strategy, if supported by targeted policies and investments that avoid distress migration.

• The number of migrants can be reduced by three major actions: cutting greenhouse gases, incorporating climate migration in development planning, and investing in improved understanding of internal climate migration.

The report is available for free from the World Bank.

Recent Papers Examine Land Use Trends and Patterns in Asia

Fri Apr 13 00:00:00 EDT 2018

Current trends suggest that the already extensive populations of the Asian megadeltas, where more than 174 million people now live less than 7 meters above sea level, will continue to grow. A new study appearing in the journal Global and Planetary Change combines updated gridded population density data with data on “night-time lights″ measured from space and a digital elevation model to assess the spatial evolution of population and development on the nine Asian megadeltas. The invited research article, “Decades of Urban Growth and Development on the Asian Megadeltas,” is authored by Lamont Research Professor Christopher Small, together with Daniel Sousa, a graduate student with the Columbia University Department of Earth and Environmental Sciences; CIESIN associate director Gregory Yetman and GIS programmer Kytt MacManus; and Christopher Elvidge of the National Oceanic and Atmospheric Administration (NOAA). The gridded population data are from the fourth version of the Gridded Population of the World data collection developed by the NASA Socioeconomic and Data Applications center operated by CIESIN.

MacManus is also a co-author of “Palm Oil in Myanmar: A Spatiotemporal Analysis of the Effects of Industrial Framing on Biodiversity Loss,” which presents the results of a spatial analysis to determine areas in Myanmar best suited for oil palm tree growth. Findings suggest potential tension in the Tanintharyi region between suitability of oil palm trees and biodiversity protection. Kristopher Nicholas, a recent Columbia College graduate and an advisee of MacManus, was the lead author of the paper, which is published in the open access journal, Global Health: Science and Practice. MacManus serves as a lecturer at Columbia College and the School of International and Public Affairs.

Tue Apr 03 00:00:00 EDT 2018

Two new data sets have been released by the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN. The India Village-Level Geospatial Socio-Economic Data Set: 1991, 2001, provides detailed administrative boundary data for India (village/town-level) together with more than 200 socioeconomic variables from the 1991 and 2001 censuses. The data are available for the 28 states and combined Union Territories in existence in 1991 and 2001. The data set was developed as part of a research project on the dynamics and determinants of land change in India by Prasanth Meiyappan of the University of Illinois and colleagues from India and from Columbia University. This is the second data set in the India Data Collection, which also includes the data set, India Annual Winter Cropped Area, v1 (2001–2016).

SEDAC has also released a new data set on global patterns of fine particulate matter (PM2.5) over nearly two decades: the Global PM2.5 Grids from MODIS, MISR and SeaWiFS Aerosol Optical Depth (AOD) with Geographically Weighted Regression (GWR), 1998–2016. The data set consists of estimated annual concentrations (micrograms per cubic meter) of PM2.5, with dust and sea salt removed, on a grid of 0.01 degree resolution, or about 1 km at the equator. This version supersedes a previous data set with coarser resolution (0.1 degree, or about 10 km) and data only through 2012. The new data set combines AOD measurements from the NASA Moderate Resolution Imaging Spectroradiometer (MODIS), Multi-angle Imaging SpectroRadiometer (MISR), and the Sea-Viewing Wide Field-of-View Sensor (SeaWiFS) with a chemical transport model. GWR is used to adjust estimates drawing on available ground-based measurements. The data set was developed by a team led by Aaron van Donkelaar at Dalhousie University in Canada.

Review Paper Recognized by Environmental Research Letters

Mon Apr 02 00:00:00 EDT 2018

The paper, “Is Voluntary Certification of Tropical Agricultural Commodities Achieving Sustainability Goals for Small-Scale Producers?: A Review of the Evidence,” has been selected by the editors of the journal Environmental Research Letters for inclusion in its exclusive ‟Highlights of 2017” collection. University Professor Ruth DeFries of the Columbia University Department of Ecology, Evolution and Environmental Biology (E3B) authored the paper together with CIESIN research associate Pinki Mondal and colleagues from Johns Hopkins University, Yale University, and Biodiversity International. Papers were selected on the basis of referee endorsement, originality, scientific impact, and breadth of appeal. The paper evaluates whether  voluntary certification (for example, Fair Trade International, Organic, Utz) of bananas, cocoa, coffee, oil palm, and tea has achieved environmental benefits and improved economic and social outcomes for small-scale farmers. The authors conclude that while not a panacea, such certification programs can sometimes play a role in meeting sustainable development goals. Environmental Research Letters is a high-impact, open-access journal covering all environmental science published by IOPscience (impact factor of 4.404 in 2016).

CIESIN Staff Contribute to Key Research Publications

Fri Mar 23 00:00:00 EDT 2018

Several CIESIN staff members have contributed to a range of publications in prominent journals and books and to a major new World Bank report. Alex de Sherbinin, associate director for Science Applications, is lead author of the chapter, “Geospatial Modeling and Mapping,” in the Routledge Handbook of Environmental Displacement and Migration. Edited by Robert McLeman of Wilfrid Laurier University and François Gemenne of the Hugo Observatory at the University of Liège, Belgium, the Handbook constitutes a major review of research on how environmental variability and change influence current and future global migration patterns and may trigger large-scale population movement. The chapter′s co-author is Ling Bai, a doctoral student in the Department of Sociology at the University of Southern California.

The World Bank report, Groundswell: Preparing for Internal Climate Migration, was released March 19 through the Bank's Open Knowledge Repository. Alex de Sherbinin and research scientist Susana Adamo are among the co-authors of the report, which examines the potential impacts of climate change on population movement within countries in Latin America, South Asia, and sub-Saharan Africa in future decades. CIESIN coordinated the study with the Institute for Demographic Research at the City University of New York and the Potsdam Institute for Climate Impact Research.

Kytt MacManus, CIESIN GIS programmer, is a co-author of the paper, “Flood Hazard Assessment from Storm Tides, Rain and Sea Level Rise for a Tidal River Estuary,” appearing in the journal, Natural Hazards. The research team led by Philip Orton of Stevens Institute of Technology found that areas along the Hudson River south of Poughkeepsie are dominated by storm surge-induced flooding, whereas areas north of Poughkeepsie to Albany are impacted more by precipitation-based flooding. The research included further development of the Hudson River Flood Impact Decision Support System, and was supported by the New York State Energy Research and Development Authority (NYSERDA).

MacManus also contributed to a second paper, “NASA’s Black Marble Nighttime Lights Product Suite,” published in the journal, Remote Sensing of Environment. A companion to the well-known “Blue Marble” image of the Earth, the Black Marble provides insight into distributions and changes in visible lights at night. The lead author of the paper, Miguel Román of the NASA Goddard Space Flight Center, is collaborating with CIESIN on two new projects funded by NASA in support of the Human Planet initiative of the Group on Earth Observations (GEO).

Members of a panel on climate change and migration at a March 20 seminar at Columbia University as part of launch activities for the World Bank report, Groundswell: Preparing for Internal Migration. Left to right: Craig Spencer, Amali Tower, Sarah Rosengaertner, and Richard Balme.

The World Bank recently published a new report, Groundswell: Preparing for Internal Climate Migration, which was co-authored by scientists from CIESIN, the City University of New York Institute for Demographic Research (CIDR), and the Potsdam Institute for Climate Impact Research. The report projects that, without concrete climate and development action, more than 143 million people—or around 2.8 percent of the population of sub-Saharan Africa, South Asia, and Latin America—could be forced to move within their own countries by 2050 to escape the slow-onset impacts of climate change. In conjunction with the report launch, Alex de Sherbinin, associate director for Science Applications and one of the report′s main authors, organized a seminar at Columbia University March 20. The seminar featured preliminary remarks by Stephen Hammer, head of climate policy for the World Bank, followed by a presentation on modeling methods and results, and an expert panel moderated by CIESIN deputy director Marc Levy. The panel featured faculty and other experts from across Columbia, including Richard Seager from the Lamont-Doherty Earth Observatory, Craig Spencer from the Mailman School of Public Health, and Sarah Rosengaertner from Columbia's Global Policy Initiative. Amali Tower, executive director of Climate Refugees, and Richard Balme, a visiting scholar from SciencesPo in France, also participated. The seminar was the second in a new seminar series on population dynamics and environmental change, organized by CIESIN, the Population Council, CIDR, and the UN Population Division. More than 60 researchers and interested individuals from the region attended.

Available for the First Time: Global Gridded Data Set on Population Distribution by Age and Sex

Wed Mar 14 00:00:00 EDT 2018

Map of Basic Demographic Characteristics: The proportion of males to females in the Global Population

The most recent update to the fourth version of the Gridded Population of the World data collection, GPW version 4.10, contains the first global data set on the spatial distribution of population broken down into different age groups by sex (male and female). The data were developed by the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN.

Prior versions of GPW  provided estimates of the total population in each latitude-longitude grid cell. Now with the inclusion of age and sex information drawn from the 2010 round of national population censuses, it is possible to map specific demographic subgroups such as elderly populations, school-aged children, young adults, and women of childbearing age. This enables users to better understand spatial variations in age structure and sex ratios within countries for specific regions of interest. The age and sex data expand GPW’s usefulness in many research and application areas, including vulnerability and risk mapping, urbanization and migration studies, and emergency response and public health applications. In addition, gridded age and sex data can help in monitoring and achieving the Sustainable Development Goals (SDGs), especially with respect to efforts to disaggregate data to support the objective to “leave no one behind,” e.g., the elderly, the young, and other subgroups who may be geographically isolated.

The new downloadable data consist of population counts and density rasters for 5-year age groups and for selected age categories (0–14, 15–64, 65 and older), as totals and by sex. A raster data set of women of childbearing age (15–49) is also available. All of the GPWv4.10 raster data sets are now available in ASCII and netCDF formats as well as GeoTiff. Files with coarser resolution (2.5, 15, 30, and 60 arc minutes) may be selected to enable faster raster processing and compatibility with data sets from other scientific domains. A vector data set, “Administrative Unit Center Points,” has been updated to include age and sex attributes.

First developed in 1994, GPW provides population estimates on a latitude-longitude grid for all land on the planet except Antarctica, created through analysis of census and administrative boundary data from every country in the world. The gridded format permits easy integration with a wide range of data, supporting research, planning, and applications in energy and water management, disaster and humanitarian response, agriculture and food security planning, public health interventions, transportation and communications development, urban and coastal zone planning, and many other aspects of sustainable development.

The free, downloadable data and descriptions, including documentation and maps, are available at http://sedac.ciesin.columbia.edu/data/collection/gpw-v4/whatsnewrev10. The data are disseminated using the Creative Commons Attribution 4.0 International (CC-BY-4.0) license, which permits free sharing, adaptation, and use of the data for both commercial and noncommercial purposes, so long as appropriate credit is given.

Population and Settlement Data and Tools Examined at Second POPGRID Meeting

Mon Mar 05 00:00:00 EST 2018

More than 40 experts on mapping of human settlements, infrastructure, and population from a range of organizations participated in the second “POPGRID″ working meeting, held at the Lamont campus February 28–March 1 and at the Population Council in New York City March 2. Organized by CIESIN with support from the Bill & Melinda Gates Foundation (BMGF) and the Earth Institute, the meeting focused on the rapidly growing number and variety of georeferenced data products aimed at improving understanding of human settlement patterns, population distribution, and associated built infrastructure. New mapping approaches are being developed that take advantage of new sources of data such as radar, night-time lights, and high-resolution remote sensing. More information about these data and how they compare is needed to support not only scientific research, but also a variety of critical applications in sustainable development, disaster risk management and response, public health planning, and resource management.

Participants in the meeting came from organizations in both the United States and Europe, including the European Commission′s Joint Research Centre, the German Aerospace Center, the Group on Earth Observations, the Oak Ridge National Laboratory of the U.S. Department of Energy, and the U.S. Bureau of the Census. Private companies such as Esri, Facebook, and Google were also represented. Increased collaboration among these groups, and between both producers and users of these data, will improve data quality and usability, reduce duplication, facilitate data access and sharing of resources, and improve the impact and effectiveness of the data for both research and applications.

A new POPGRID web site has been released that brings together information about the different data products currently available and that will serve as an access point for the growing number of tools that provide visualization and analysis tools for the different data sets. Three POPGRID scientific sessions were held at the fall American Geophysical Union meeting in New Orleans in December 2017, and several additional sessions are scheduled April 14 at the annual meeting of the American Association of Geographers, also in New Orleans.

Creator of First Global Gridded Population Data Set Passes Away

Wed Feb 28 00:00:00 EST 2018

Waldo Tobler

Waldo Tobler, world-renowned geographer and cartographer and Professor Emeritus at the University of California, Santa Barbara, passed away February 20 at the age of eighty-eight. Among his many accomplishments, Tobler created the first global gridded population data set, working with colleagues, Uwe Deichmann, Jan Gottsegen, and Kelley Maloy. Tobler also formulated the so-called first law of geography: “Everything is related to everything else, but near things are more related than distant things.” He was an early pioneer in applying digital technologies and mathematical methods to geographic research and visualization, inventing new map projections, reallocation methods, and spatial analysis techniques.

In 1994, Tobler was a key participant in the Global Demography workshop held in Saginaw, Michigan, organized by the Science division of what was then the Consortium for International Earth Science Information Network. CIESIN supported Tobler′s development of the initial version of the Gridded Population of the World (GPW) data set, which was based on population and administrative boundary data for about 19,000 administrative units. CIESIN has continued to refine and improve GPW for more than two decades, recently releasing version 4.10 through the NASA Socioeconomic Data and Applications Center (SEDAC).

Tobler was a member of the U.S. National Academy of Sciences, recipient of the O.M. Miller Cartographic Medal of the American Geographical Society (AGS), and winner of Esri's Lifetime Achievement in GIS Award, among other honors. For more information about Tobler's work and the planned memorial service, see his department′s Web site.

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.

The 2018 winter meeting of the Earth Science Information Partners (ESIP) was the focal point for a set of co-located meetings in Bethesda and Gaithersburg, Maryland, January 8–12 to which several CIESIN staff members contributed. Senior digital archivist Robert Downs participated in the Enabling FAIR Data Project: Targeted Adoption Group Workshop January 8, part of a new initiative recently launched by the American Geophysical Union to develop standards to connect researchers, publishers, and data repositories in support of the Findable, Accessible, Interoperable, and Reusable (FAIR) data principles. At the ESIP winter meeting, Downs served on the plenary panel, ‟Wildfires, Hurricanes, and Drought, Oh My!,” describing hazard-related data and tools available from the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN. He also gave presentations on data management training, information quality, and data risk factors in a number of other sessions. Downs was re-elected as the Type 1 Representative to the ESIP Governance Committee during the business meeting.

Two other joint meetings were held January 11. Alex de Sherbinin, associate director for Science Applications, participated in the General Assembly of the EarthCube Council of Data Facilities, a federation of existing and emerging geoscience data facilities supporting the National Science Foundation′s EarthCube community. He represented the International Council for Science (ICSU) World Data System (WDS) in his capacity as a member of the WDS Scientific Committee, and gave a presentation, “Certification for Open and Trustworthy Data Repositories.″ CIESIN director Robert Chen also attended the ESIP winter meeting, participating in an all-day joint meeting with the All Hazards Consortium (AHC) focused on operational readiness of data and data services for emergency response to disasters. The AHC supports industry, government, and other stakeholders in their efforts to coordinate restoration of power and other utilities after hurricanes and other major disruptions. Chen gave a short presentation, “Operational Readiness of SEDAC Data and Services,″ at the  session, “Operational Readiness Levels: Measuring the Benefit of Trusted Data for End Users,″ organized by the ESIP Disaster Cluster. The SEDAC Population Estimation Service is an element of the AHC Multi-State Fleet Response Working Group GeoCollaborate service.

Downs also attended the 8th Working Group/Interest Group Collaboration meeting of the Research Data Alliance (RDA) January 11–12 at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland. He represented the Repository Platforms for Research Data Interest Group, which he co-chairs.

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.
