Environmental Sustainability Indicators and Trends

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. CIESIN staff members organized or co-organized seven sessions; presented more than twelve invited, oral, e-lightning, and poster papers; and served as co-authors on at least nine other papers. CIESIN director Robert Chen convened three sessions on exposure and vulnerability assessment for hazard, coastal, climate, and health risks and served as co-chair of one of them. Associate director for Science Applications Alex de Sherbinin also co-chaired the poster session in this series. Senior digital archivist Robert Downs co-organized a session on improving use of the FAIR principles (Findable, Accessible, Interoperable, and Reusable), as well as several sessions on the use of earth and space science data.

Also attending the conference were associate director for Geospatial Applications Greg Yetman, GIS developer Kytt MacManus, and Columbia College student Dorothee Cleophee Grant, a former summer intern. Yetman gave an oral presentation on population data models for settlement extents and a NASA Hyperwall talk, “Are You at Risk? Linking Hazard and Exposure Data for Research and Applications.” MacManus gave an oral presentation on new sources for the updated version of low-elevation coastal zone data, expected to be released in early 2020. He also presented a poster paper on a nighttime lights dataset recently released by the NASA Socioeconomic Data and Applications Center (SEDAC), to which Grant had contributed.

While at the conference, de Sherbinin gave invited talks and served as a panelist in three different sessions on open data digital repositories for developing countries, climate vulnerability mapping, and managed retreat due to climate change. Chen gave presentations on the FAIR principles and open data and on the use of Earth Observations to operationalize the fundamental geospatial data themes established by the United Nations. Downs gave an e-lightning talk on citing open data and presented a case study on data sharing and data management guidance developed by the Group on Earth Observations (GEO). Both Downs and Chen also served as judges on student papers.

The week brought together more than 1,400 representatives of GEO Member governments and GEO Participating Organizations. CIESIN director Robert Chen served as the head and only delegate of the UN Sustainable Development Solutions Network (SDSN), in his capacity as a co-chair of the SDSN Thematic Research Network on Data and Statistics (TReNDS). SDSN recently joined GEO as a Participating Organization. Senior digital archivist Robert Downs represented the International Science Council′s World Data System (ISC-WDS), which includes the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN as a regular member.

On November 4, Downs participated in a workshop, “Data for Our Planet,” which was co-organized by the Earth Science Information Partners (ESIP) and held at the Australian Academy of Science. He gave the presentation, “Infrastructure for Enabling the Use of Integrated Earth Science Data by Heterogeneous Communities.″ On November 5, Chen served as a panelist in a targeted side event, “Earth Observations and Modeling: Dialogue for Added Value and Knowledge,″ that he helped organize with Danielle Wood and William Sonntag of the Massachusetts Institute of Technology (MIT). He also participated as a panelist in the key side event, “Delivering on the Sustainable Development Goals,″ moderated by Argyro Kavvada and Lawrence Friedl of NASA Applied Sciences. On November 5 Chen and Downs led and organized a meeting of the new joint GEO Data Sharing and Data Management Principles Working Group. They also participated in meetings of the organizing committee for the GEO Data and Knowledge Week, to be held in Beijing in February 2020. Information about SEDAC and a use case of the SEDAC Population Estimation Service integrated into the GeoCollaborate tool were featured at the US GEO exhibit, which had a “Jazz Observatory″ theme.

CIESIN geographic information specialist Jane Mills and senior geographic information specialist Linda Pistolesi were among the presenters at the 2019 European Forum for Geography and Statistics (EFGS), organized in Manchester, England, October 9–11. This year′s forum focused on how the integration of statistics and place can enhance understanding of diverse population and world issues. In the session, “Future Geospatial Thinking,” Mills outlined plans for the fifth version of Gridded Population (GPW) of the World now under development, and discussed progress made by the POPGRID Data Collaborative, an initiative to promote data access and use of diverse georeferenced data sets on population, human settlements, and infrastructure. For the session, “Leaving No One Behind,” Pistolesi presented two strategies implemented by the Geo-Referenced Infrastructure and Demographic Data for Development (GRID3) program to improve subnational boundaries in low- and middle-income countries. The 2019 EFGS was organized by the Office for National Statistics and Ordnance Survey Great Britain with support from the Statistical Office of the European Union and the EFGS.

Several publications authored or co-authored by CIESIN staff have been published recently. Associate director for Science Applications Alex de Sherbinin is lead author of the paper, “Climate Vulnerability Mapping: A Systematic Review and Future Prospects,” appearing in the peer-reviewed journal, WIREs Climate Change. The article reports on a study to systematically assess 84 climate vulnerability mapping studies, with the goal of encouraging further methodological refinement and identifying outstanding examples that could help to guide future work in this area. The study benefited from two workshops held in 2017 supported by National Socio‐Environmental Synthesis Center (SESYNC) and funded by the U.S. National Science Foundation.

The article, “Allocating People to Pixels: A Review of Large-Scale Gridded Population Data Products and Their Fitness for Use,” has been published in the journal Earth Systems Science Data. The lead author is Stefan Leyk of the University of Colorado. CIESIN contributors are de Sherbinin, research scientist Susana Adamo, senior systems analyst Kytt MacManus, senior geographic information specialist Linda Pistolesi, and deputy director Marc Levy. Former CIESIN research scientist Deborah Balk, who is now associate director of the Institute for Demographic Research at the City University of New York (CUNY), is also a co-author. The paper is an outcome of the POPGRID Data Collaborative, an international effort to coordinate and improve the utility of global-scale gridded population data.

Former CIESIN visiting scholar Douglas Sathler is lead author of “Assessing the Regional Context of Migration in the Brazilian Amazon through Spatial Regression Modeling” in the journal Applied Geography. Co-authors include Adamo, de Sherbinin, and senior research associate Paola Kim-Blanco. The article examines spatial patterns of both in-migration and outimigration in the Brazilian Amazon during the period 2000–2010. Sathler is a researcher with the Center for Geosciences of the Interdisciplinary College in Humanities at the Federal University of Vales do Jequitinhonha e Mucuri (UFVJM) in Diamantina, Brazil.

Greg Yetman, associate director for Geospatial Applications, is a co-author on the paper, “Evaluating Nighttime Lights and Population Distribution as Proxies for Mapping Anthropogenic CO₂ Emission in Vietnam, Cambodia, and Laos.” Andrea Gaughan of the University of Louisville is lead author of the paper, which was published in Environmental Research Communications. The paper stems from work organized by the WorldPop project.

Senior digital archivist Robert Downs is lead author of the Technical Note, “Reuse Readiness Assessment of Data Quality Software Products (ESDS-RFC-039),” co-authored with Hampapuram Ramapriyan of Science Systems and Applications, Inc. and Yang Wei of the Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC). The Data Quality Working Group of the Earth Science Data and Information System (ESDIS) Standards Office (ESO) recommends this assessment for use in NASA Earth Science Data Systems.

CIESIN director Robert Chen, deputy director Marc Levy, and associate director for Science Applications Alex de Sherbinin joined nearly 2,000 delegates from around the world in Dubai, United Arab Emirates (UAE) October 22–24 for the second United Nations (UN) World Data Forum. The Forum brought together representatives from national statistical offices, UN agencies, development organizations, civil society groups, industry, academia, and other stakeholders to assess critical data challenges in efforts to meet the 2030 Sustainable Development Goals (SDGs) and to collaborate in applying rapidly evolving data science approaches to meet these challenges. Chen co-organized two parallel sessions on population monitoring and geospatial data issues, including one focused on the Geo-Referenced Infrastructure and Demographic Data for Development (GRID3) project for which CIESIN is the coordinating partner. He also discussed the growing use of remote sensing and population data in sustainable development applications in two panels, highlighting new data and services available from CIESIN and other organizations. In a session on data innovation for migration and development interventions, de Sherbinin reported on recent efforts led by the World Bank to model climate-induced migration and displacement.

The Forum served as a focal point for a range of complementary meetings and networking opportunities. On October 21, Chen, de Sherbinin, and Levy participated in a pre-meeting of the Global Partnership for Sustainable Development Data (GPSDD), in which CIESIN is an Anchor Partner. Chen remained in Dubai through October 26 to co-chair a meeting of the Thematic Research Network on Data and Statistics (TReNDS) of the UN Sustainable Development Solutions Network (SDSN). 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). Sandra Baptista, senior research associate, is a co-project investigator, with Marc Levy.

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.

Announced at the World Economic Forum held January 25–29 in Davos, Switzerland, the 2012 Environmental Performance Index (EPI) produced by CIESIN and Yale University’s Center for Environmental Law and Policy (YCELP), in collaboration with the World Economic Forum and the Joint Research Center in Ispra, Italy, identifies Switzerland as first in addressing pollution control and natural resource management challenges. Iraq is ranked last. The EPI has been produced every two years since 2006. The 2012 EPI ranks 132 countries, using 22 indicators in ten major policy categories including air and water pollution, climate change, biodiversity, and forest management.

For the first time a complementary index showing country improvement from 2000 to 2010, the Pilot Trend Environmental Performance Index (Trend EPI), was released. Latvia was ranked number one in the Trend EPI, with Russia in last place. The U.S., which is 49^th in the EPI, was just 77^th in the Trend EPI, implying few recent gains in addressing environmental issues.

Data sets making up the EPI were contributed from the International Energy Agency, remote sensing research groups at Battelle and University of Maryland, the UN Food and Agriculture Organization, and other entities. Lack of data in certain areas—in particular, waste management, toxic exposures, agricultural sustainability and water resources—continue to limit the ability of the EPI to contribute towards the understanding necessary to develop policies for safeguarding the environment.

The Socioeconomic Data and Applications Center (SEDAC) has released a new data set, Effects of Climate Change on Global Food Production under SRES Emissions and Socio-Economic Scenarios. The data set was developed by scientists from the NASA Goddard Institute for Space Studies (GISS).

Over the past few decades coastal waters throughout the world have received an increased influx of nutrients from land-based sources. The resulting change in water quality has many possible implications for coastal and marine ecosystems. In extreme cases eutrophication results, where excess nutrients in the water stimulate excessive plant growth. This can lead to hypoxia—oxygen-depleted “dead zones”—and harmful algal blooms.

Coastal water quality over time may be assessed by measuring chlorophyll concentrations as an indicator of algae biomass. A new global data set, Indicators of Coastal Water Quality, aims to identify near-coastal areas that have improving, declining, and stable chlorophyll concentrations in order to help identify areas that may need management intervention. The data set uses chlorophyll-a concentrations derived from NASA’s sea-viewing wide field-of-view sensor (SeaWiFS) to analyze trends over a ten year period (1998–2007). This data set is a result of a pilot effort, and the methodology will be further refined as part of a NASA Decisions feasibility project.

The 2010 Environmental Performance Index (EPI), which ranks 163 countries on environmental performance, has been released at the World Economic Forum Annual Meeting 2010 in Davos, Switzerland. The Index, produced every two years since 2006 by researchers at CIESIN and Yale University’s Center for Environmental Law and Policy, is based on twenty-five indicators grouped within ten core policy categories—including environmental health, air quality, water resource management, biodiversity and habitat, forestry, fisheries, agriculture, and climate change—in the context of two objectives: environmental health and ecosystem vitality. The EPI’s proximity-to-target approach, in which each country’s performance is measured against clearly defined targets, enables comparisons among countries with very different characteristics.

Although some rankings have changed dramatically—the U.S. dropped from 39^th to 61^st place since the 2008 index, for example—so too have the methodologies and data. “A better focus is the comprehensive country profiles, which present a measurement across the different environmental indicators,” says CIESIN senior research associate Alex de Sherbinin, a co-author on the report. These profiles, designed by CIESIN research associate Valentina Mara in conjunction with the Yale team, show a country’s scores for the indicators, policy categories, and objectives. Drilling down here, de Sherbinin points out, can help decision makers identify the needed focus of attention for a particular country. Geographic information specialist Malanding Jaiteh, CIESIN deputy director and EPI project leader Marc Levy, and senior research staff assistant Paola Kim were also part of the CIESIN team.

Analysis shows that income is a major factor in high environmental performance, but that policy choices may trump economic capacities. For example, the differences between neighboring countries Chile (ranked 16^th) and Argentina (70^th), or between Malaysia (55^th) and Thailand (68^th), have a lot to do with different approaches to environmental policy and governance. The biggest changes this year were seen in the scores for air pollution and effects on ecosystems, and a new indicator, water scarcity, was added. The indicators were drawn from international organizations such as the World Bank, the UN Development Programme (UNDP), and the Food and Agriculture Organization of the United Nations (FAO). Some of the data sets are drawn from government reporting that is not subject to external validation, and incomplete data have resulted in incomplete representation of countries. The report calls for greater investment by the world community in environmental monitoring, and for data sharing and transparency on the part of national governments.

TerraViva! SEDAC Viewer is a map viewer and standalone software application that uses a powerful data-viewing engine and tools to enable the visualization and integration of hundreds of socioeconomic and environmental variables and layers, including a range of satellite-based data. A three-part tutorial that explains how to use TerraViva! is now available through the YouTube Web site. The tutorial was produced by senior research associate Alex de Sherbinin and senior media designer Al Pinto, under the auspices of the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN.

The NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN has released the 2009 National Resource Management Index (NRMI). This version of the NRMI has updated data and improved methodology for the eco-region protection indicator, one of the four indicators that make up the NRMI. The improvements included the exclusion of international protected areas, many of which lack effective protection (the ones that do already have a national designation), and improved coastal boundary matching between biomes and national boundaries using the highest resolution coastal data available.

The NRMI is a composite index of four measures. In addition to the eco-region protection indicator, the indicators include: access to improved sanitation, access to improved water, and child mortality. In response to the search for a natural resources management indicator initiated by the the Millennium Challenge Corporation (MCC), the NRMI was first developed in May 2005 by a consortium led by CIESIN and including the Yale Center for Environmental Law and Policy (YCELP), the University of New Hampshire Water Systems Analysis Group, the Wildlife Conservation Society, and the Columbia University Tropical Agriculture Program. The MCC uses the NRMI as as one of its performance indicators to help determine country eligibility for its foreign aid programs.

Anthropogenic biomes, also known as “anthromes” or “human biomes,” describe the terrestrial biosphere in its contemporary, human-altered form using global ecosystem units defined by patterns of sustained direct human interaction. In a paper presented in the journal, Frontiers in Ecology and the Environment, Ellis and Ramankutty (2008) delineate 21 anthropogenic biomes based on population density, land use, biota, climate, terrain and geology. The anthropogenic biomes are further grouped into six major categories: dense settlements, villages, croplands, rangeland, forested, and wildlands. A new Web site, “Anthropogenic Biomes (version one),” provides access to the spatial data sets described in the paper. Available in raster GeoTiff and GRID formats, the data may be downloaded as one global grid or a grid for each of the six populated continents. The methodology involves a multi-stage procedure where “anthropogenic” cells are first separated from “wild” cells based on presence of population, crops, or pastures. A detailed description of the methods utilized to produce the data, as well as research results, may be downloaded from the Web site.
