The NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN has recently released three global data sets that utilize satellite-based remote sensing data to help characterize critical aspects of human-environment interactions: Trends in Global Freshwater Availability from the Gravity Recovery and Climate Experiment (GRACE), v1 (2002 – 2016), Development Threat Index, v1 (2015), and Altimeter Corrected Elevations (ACE2), v2 (1994 – 2005).

The ability to measure trends in global freshwater availability has been made possible by NASA′s Gravity Recovery and Climate Experiment (GRACE). By measuring small changes in Earth′s gravity field, the GRACE mission was able to track key dynamics of the global water cycle at a spatial resolution of 0.5 degrees during the period from 2002 to 2016. Terrestrial water availability storage is the sum of groundwater, soil moisture, snow and ice, surface waters, and wet biomass, expressed as an equivalent height of water. The data are valuable in helping to evaluate and predict emerging threats to water and food security. Part of SEDAC's Satellite-Derived Environmental Indicators (SDEI) data collection, the data set was developed by researchers from the NASA Goddard Space Flight Center and Jet Propulsion Laboratory and from National Taiwan University.

The Development Threat Index, v1 seeks to map terrestrial global, future development threats resulting from agricultural expansion, urban expansion, and energy development (conventional oil and gas, unconventional oil and gas, coal, mining, biofuels, solar, and wind). Individual threat layers draw on several different data sets derived in part from satellite remote sensing data, including the Global Grid of Probabilities of Urban Expansion to 2030, the Global Roads Open Access Data Set (gROADS), and the Global Reservoir and Dam (GRanD) data sets, all available through SEDAC. The Index has been produced on a 50 square kilometer grid by a team from The Nature Conservancy, the University of Minnesota, and the University of British Columbia. It has been added to SEDAC′s Land Use and Land Cover (LULC) data collection, but shares similar objectives with the Human Footprint data also distributed by SEDAC (e.g., Human Footprint, 2018 Release).

The ACE2 data set is based on a Global Digital Elevation Model (GDEM) derived primarily from multi-mission Satellite Radar Altimetry in combination with data from the Shuttle Radar Topography Mission (SRTM). By using data from an altimeter, an instrument that uses radar to measure height, researchers were able to better assess ground elevation in areas with high tree cover. This represents an improvement over the original SRTM data, which only measured the top of the canopy. ACE2 is intended for research and applications such as flood risk assessment, landslide modelling, urban planning, and sea level rise impact assessment. In light of ongoing efforts to improve GDEMs, SEDAC has decided to preserve this version for future analysis and intercomparison as part of a new Digital Elevation Data Collection (DEDC). The data set was developed by a team from the UK and the European Space Agency.

CIESIN bids farewell to Kira Topik, senior research staff assistant, who has moved to the West Coast to pursue other opportunities.

The User Working Group (UWG) of the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN met in Washington DC June 6–7. The meeting was chaired for the first time by Barbara Ryan, former executive director of the Group on Earth Observations (GEO) and winner of the 2018 William T. Pecora Individual Award given by the U.S. Geological Survey. Nine UWG members participated in person, including new members Ryan and Navin Ramankutty of the University of British Columbia. Brian O'Neill of the University of Denver participated remotely in a breakout session. UWG member Dave Jones of StormCenter Communications gave an informal lunch talk, “Creating a Unified Response During Disasters by Sharing Trusted Data Across Platforms in Real-Time.″ The UWG received updates on SEDAC strategic priorities related to global-scale human population and settlement data and support for the 2030 Agenda for Sustainable Development. Potential new activities to archive and disseminate spatially explicit scenarios of Shared Socioeconomic Pathways (SSPs) and to update low-elevation coastal zone (LECZ) data were reviewed in detail, together with plans for expanding training on the integration of remote sensing and socioeconomic data. A new process for third-party submissions of data was also discussed.

The UWG meets in person once per year, typically either at Columbia University in New York City or in Washington DC. More than 10 representatives from NASA headquarters and the Goddard Space Flight Center participated in this year's meeting, including Nancy Searby of the NASA Applied Sciences Program, who has recently been appointed as SEDAC's program scientist. Three other NASA Distributed Active Archive Centers (DAACs) also sent observers.

A new digital game for players of any age, created by the New York Hall of Science (NYSCI) and Design I/O, uses theories of playful learning to encourage computational thinking and scientific inquiry. CIESIN was a partner in the project, supported by the U.S. National Science Foundation (NSF), that sought to develop innovative ways to teach kids about ecological concepts using approaches drawn from the computer sciences.

The interactive game, The Pack, takes place in a futuristic world called Algos, where food and water are scarce. The challenge of the game is to restore ecosystem balance. The player marshalls different creatures to perform a variety of tasks—digging, moving, holding, grabbing, seeking, and bumping—in order to move water around the environment and find seeds. By arranging and repeating tasks in different order, the player can develop, test, and modify new algorithms to achieve specific objectives.

The Pack is an “open world,” meaning players can explore and choose their objectives more freely than in a linear game with directed goals. As players continue in the game, they encounter increasingly complex opportunities to develop and use their algorithmic thinking skills. For young players, the game seeks to develop a problem-solving mindset and to strengthen social and strategic-thinking skills.

The game leverages increased awareness in the education field that children learn best through play, especially in science. The NYSCI is a pioneer of “design-make-play,” an approach that is central to all of NYSCI's exhibits and activities at its museum location in Queens, New York. Based on the two concepts, awareness of the environment and computational thinking, The Pack is meant for both informal and formal settings in support of Science, Technology, Engineering, Mathematics, and Computing (STEM+C) education.

The Pack was inspired by the award-winning Connected Worlds installation, which came out of a previous NSF-funded collaboration between NYSCI, Design I/O, and CIESIN. This immersive fantastical virtual world lets visitors playfully and tactilely interact with and explore the interdependence of different habitats within a larger ecosystem. The JPB Foundation supported the final production and release of both Connected Worlds and The Pack.

The Pack is free and available for download for Mac OSX, Windows, and iOS devices (iPhone, iPad, and iPod touch). The game is intended for children 4 years old and up. It currently has a rating of 4.8 out of 5 stars in Apple's App Store.

“Earth Observations for Impact” was the theme this year of the annual Group on Earth Observations (GEO) Symposium 2019, held at the World Meteorological Organization (WMO) headquarters in Geneva May 27–29.
