Google Earth Engine Developers Hosted by CIESIN

February 5, 2016

A team from Google Earth Engine, Google’s cloud platform for petabyte-scale analysis of satellite imagery and other geospatial data, visited CIESIN February 4–5 to provide training and discuss potential areas of collaboration. Tyler Erickson, Matt Hancher, and Allison Lieber met in the morning of February 4 with staff and researchers from CIESIN, the Lamont-Doherty Earth Observatory, and the International Research Institute for Climate and Society. That afternoon at the Comer Building, Hancher and Erickson led a public workshop tutorial on using Google Earth Engine. Hancher subsequently gave an evening presentation at Butler Library on Columbia's Morningside campus, in which he talked about the trends and technologies that have informed Google’s development of the Earth Engine platform over the past six years. On February 5, CIESIN director Robert Chen, deputy director Marc Levy, and associate director for geospatial applications Gregory Yetman met with Lieber and Rebecca Moore, Google's director of engineering for Google Earth, Earth Engine and Earth Outreach, to explore collaboration on population data access and integration. Originally conceived in 2009 as a platform for global forest monitoring, Earth Engine today is used by scientists, governments, and organizations around the world in diverse areas, ranging from food and water security to disaster risk management and public health to biodiversity and climate change adaptation.

Moving from Talk to Action Urged in Planetary Security Presentation

February 2, 2016

The post-1990 trend towards lower global insecurity is in reversal, with unanticipated and poorly managed climate shocks partly to blame, according to Marc Levy, CIESIN deputy director, in a presentation given in New York City January 25. The event, “Planetary Security: An Action Agenda on the Frontlines of Climate Change,” was hosted by the government of The Netherlands. Levy’s talk, “Time to Move from Talk to Action,” argued against scare tactics and overwhelming the public with large amounts of data. Among other recommendations, he called for the development of tools, techniques, and methods that drive effective action coalitions.

Latest Environmental Performance Index Released at World Economic Forum

February 1, 2016

More deaths globally occur from poor air quality than from water, and more than half the world’s population is subject to unsafe air—these are some of the findings of the 2016 Performance Environmental Index (EPI) released January 23 at the annual meeting of the World Economic Forum in Davos, Switzerland. The biennial report, produced this year by the Yale Center for Environmental Law & Policy (YCELP), Yale Data-Driven Environmental Solutions Group at Yale University, and CIESIN, in collaboration with the Samuel Family Foundation, McCall MacBain Foundation, and the World Economic Forum, 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 2016 EPI measures the performance of 180 countries in nine categories of environmental concern.

A major goal of the EPI is to organize the best available information to make it as relevant as possible.  “Even when data exists, policymakers often struggle to apply this information appropriately,” notes Marc Levy, CIESIN deputy director. “The EPI works to identify and address these blind spots within existing policy goals. For instance, a new biodiversity indicator weeds out protected areas that do not intersect with species’ habitats, showing where national parks may be ineffective at protecting species.”  

The 2016 version of the EPI awards Finland the top slot, followed by Iceland, Sweden, Denmark, and Slovenia. These five environmental leaders have policies that target protections to natural and built environments, with strong commitments to renewable energy. Finland’s top rank indicates its commitment to achieving a carbon-neutral society that will not exceed nature’s carrying capacity by 2050. Countries performing poorly—such as lowest ranked Somalia, Eritrea, Madagascar, Niger, and Afghanistan—are reminders that stable governance is necessary for effective environmental management and conflict disrupts environmental performance. Around one-third of countries that were scored on Climate and Energy are reducing their carbon intensity, and globally, trends in carbon intensity show a slight decline.

Access to Climate, Earth Science, and Social Science Data Addressed in Multiple Meetings

January 29, 2016

Experts gathered in Geneva, Switzerland; Huntsville, Alabama; and Chapel Hill, North Carolina, for three different technical meetings addressing data access and management of scientific data related to climate change, remote sensing, and the social sciences. Alex de Sherbinin, associate director for science applications, participated in an experts meeting January 26–27 in Geneva, organized by the Intergovernmental Panel on Climate Change (IPCC) to examine the future role and activities of its Task Group on Data and Scenario Support for Impact and Climate Analysis (TGICA). The TGICA oversees the IPCC Data Distribution Center (DDC), which is co-managed by the British Atmospheric Data Center (BADC), the World Data Center-Climate in Germany, and the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN.

At the same time in Huntsville, CIESIN director Robert Chen, in his capacity as manager of SEDAC, attended the annual meeting of the NASA Distributed Active Archive Center (DAAC) managers hosted by the Global Hydrology Resource Center (GHRC) DAAC at the University of Alabama in Huntsville. Together with NASA personnel from the Goddard Space Flight Center, the DAAC Managers planned cross-DAAC activities to improve the ability of users to seamlessly access, integrate, and analyze diverse Earth and social science data available from the NASA Earth Observing System Data and Information System (EOSDIS).

Chen subsequently traveled to the University of North Carolina at Chapel Hill for a workshop on public access to social science data, organized by the Minnesota Population Center (MPC) with support from the U.S. National Science Foundation (NSF). The workshop brought together more than 25 scientists and data experts from a diverse set of social science disciplines to develop recommendations to the NSF on how to improve data management plans and their implementation. Chen is a member of the workshop organizing committee that is drafting the workshop report and recommendations.

New Project Focuses on Learning about Computing and Ecosystems

January 22, 2016

The New York Hall of Science (NYSCI) in Queens, New York, has launched a new project, Computational Thinking in Ecosystems (CT-E), that seeks to integrate computing concepts and skills with learning about ecosystems in both formal and informal educational settings. CIESIN director Robert Chen is co-principal investigator of the effort, which is led by Stephen Uzzo of NYSCI. Supported by the STEM+Computing Partnership (STEM+C) initiated by the U.S. National Science Foundation, the two-year project is developing innovative ways to engage students with hands-on tools to develop and use computer programming as part of learning about ecological systems and how scientists study them. CT-E builds on a previous collaboration between NYSCI, CIESIN, and Design I/O that led to the design and implementation of NYSCI's unique immersive, interactive installation, Connected Worlds. One of the planned outcomes is development of a tablet-based interface that allows students to take home elements of the Connected Worlds exhibit for further game-based learning.

Geospatial Data Preservation and Climate Change Mitigation and Adaptation the Focus of New Publications

January 14, 2016

Geospatial data management, curation, and preservation are the focus of three special issues of the Journal of Map & Geography Libraries, guest-edited by senior digital archivist Robert Downs. Due to a large number of high quality submissions, Downs and the editorial team were able to expand the original planned special issue into a sequence of three. The first issue, published in September 2015, contains an editorial by Downs, “Management, Curation, and Preservation of Geospatial Data: Introductory Perspectives,″ and six research articles. The second issue, published in December 2015, includes another introductory editorial, “Progress on the Management, Curation, and Preservation of Geospatial Data,″ and five more articles. The third special issue will be released in early 2016.

CIESIN research scientist Susana Adamo has published the opinion piece, “About Mitigation, Adaptation, and the UNFCCC’s 21st Conference of the Parties,” in REBEP-Revista Brasileira de Estudos de População. She argues for greater attention to linkages between mitigation and adaptation, and in particular to the role of population dynamics, in the context of international climate negotiations. Also appearing in the same journal is the paper, “Climate change and mitigation in the forestry sector: REDD+, national policies and local sustainable development in the Legal Amazon,″ by visiting senior research scientist Douglas Sathler, with Adamo and Everton Lima as co-authors.

New Population and Urbanization Data Released for Testing

January 12, 2016

The NASA Socioeconomic Data and Applications Center (SEDAC) has released three new geospatial data products for external user testing.

The Global Urban Heat Island data set estimates the average land surface temperature within urban areas in degrees Celsius (summer daytime maximum and nighttime minimum), as well as the difference between those temperatures and the temperatures in surrounding rural areas, defined as a 10-kilometer buffer around the urban extent.

The Global Grid of Probabilities of Urban Expansion data set assesses likely future areas of urban expansion up to the year 2030. The projections are based on a model of global urban land-cover change developed by Karen C. Seto of Yale University, Burak Güneralp of Texas A&M University, and Lucy R. Hutyra of Boston University, described in a 2012 paper published in the Proceedings of the National Academy of Sciences.

The Gridded Population of the World, version 4 (GPWv4), data collection is the fourth version of SEDAC′s flagship data product, which models the global distribution of human population on a continuous surface. New features of GPWv4, which is expected to be released in production in early 2016, include more recent census data; a smaller grid size; and many more input census units.

Users are invited to submit comments and suggestions regarding these test versions of the data through the online “Feedback and Support″ link on the SEDAC Web site or by contacting SEDAC User Services at ciesin.info@ciesin.columbia.edu. A free Earthdata Login is now required to download data from SEDAC.
