Climate Impacts, Vulnerability, and Adaptation

Source: Understanding Flood Vulnerability: A Case Study of Harris County (StoryMap)

Climate change disproportionately affects the poor and socially vulnerable. The scientific community is responding in its commitment to data and services development that can advance environmental justice. A recent NASA Earthdata Backgrounder profiles some of the work the NASA Socioeconomic Data and Application Center (SEDAC) is doing in this area.

The backgrounder describes a research project focused on the low-wealth, predominately Black community of the Hampton Roads region of Norfolk, VA, which is experiencing rising sea level rise in part because the land area is sinking. SEDAC population data was paired with satellite data to reveal high population density combined with anomalously high sea surface height in this area, identifying high vulnerability. Integrating different types of data in this way lets planners and policymakers make better-informed mitigation decisions that take into consideration social as well as physical impacts of sea-level rise, better insuring environmental justice for vulnerable communities.

In a second example, in collaboration with the International Research Institute for Climate and Society (IRI), SEDAC helped develop an index that assesses flood vulnerability for Harris County, Texas. Taking a multidisciplinary approach to capturing resilience and susceptibility to flooding, 15 indicators were combined into an aggregate index. The tool can visualize flood vulnerability at the block group level for Harris County and analyze relative flood vulnerability across the region, improving prioritization of flood remediation policies and aid.

CIESIN director Robert Chen, with associate director for Science Applications Alex de Sherbinin and research scientist Susana Adamo, helped organize and co-lead a NASA Equity and Environmental Justice virtual workshop, in their respective SEDAC roles as manager, deputy manager, and project scientist. The workshop report was released in December 2021.

Tuholske et al., PNAS, 2021 Annual municipality-level increases in the rate of urban population exposure to extreme heat, 1983–2016.

Rising air temperatures associated with climate change are a threat to cities throughout the world, but especially to the urban poor. The poor generally have fewer adaptive resources and less protective shelter; they have greater health vulnerability to extreme heat, and lower ability to evacuate. These conditions can be exacerbated by the urban heat island effect, where closely spaced structures with lots of pavement and limited green space, common to poorer neighborhoods worldwide, retain heat more readily and for a longer duration. Better understanding of patterns of local exposure to extreme heat is critically needed to design adaptive measures and improve health outcomes. However, until now, global, fine-resolution data on the intersection of extreme heat and population distribution in urban settings have been limited.

A new study published in the prestigious journal, Proceedings of the National Academy of Sciences (PNAS), “Global Urban Population Exposure to Extreme Heat,” is the first to combine temperature, relative humidity, and population data to provide a more detailed and comprehensive view of how extreme heat exposure is likely to impact many more people in cities around the world in the coming decades. Lead author is Earth Institute Fellow Cascade Tuholske, based at CIESIN, with co-authors Kelly Caylor, Chris Funk, Andrew Verdin, Stuart Sweeney, Kathryn Grace, Pete Peterson, and Tom Evans. The team used new, fine-resolution temperature, relative humidity, and population data to assess urban extreme heat exposure in more than thirteen thousand cities, from 1983 to 2016. Using a daily maximum wet bulb globe temperature threshold of 30°C (86°F)—which accounts for a combined impact of both temperature and humidity on human health and wellbeing—global exposure was seen to increase nearly 200% from 1983 to 2016. Total urban warming elevated the annual increase in exposure by approximately 50% compared to urban population growth alone. Exposure increased for nearly half of urban settlements worldwide, which in 2016 comprised 1.7 billion people.

The authors also found that how total urban warming and population growth drove the trajectory of exposures was not evenly distributed, thus reinforcing the importance of crafting adaptation measures that address local needs. Their findings further suggest that previous research has underestimated extreme heat exposure, underscoring the necessity for improved data to support the development of targeted adaptions such as early warning systems to reduce harmful effects, especially on the urban poor.

CIESIN through its NASA Socioeconomic Data and Applications Center (SEDAC) has released two new data sets, one characterizing historical air quality over the period 1998–2016, and the second projecting urban land extent into the future through 2100 under different shared Socioeconomic Pathways (SSPs). The first data set, “Annual PM2.5 Concentrations for Countries and Urban Areas, 1998–2016,” provides annual mean estimates of levels of particulate matter (particles with diameters of 2.5 microns or less) in the atmosphere, derived from observations from satellite-based sensors, for countries and urban areas. The national averages are population-weighted. This data set is based on a gridded data set developed by van Donkelaar et al., also available from SEDAC.

The data set “Global One-Eighth Degree Urban Land Extent Projection and Base Year Grids by SSP Scenarios, 2000–2100” was developed by Jing Gao of the University of Delaware and Brian O’Neill, now director of the Joint Global Change Research Institute at the University of Maryland. The data set characterizes global, spatially explicit urban land scenarios consistent with the SSPs, projected from the base year 2000 to the year 2100 at ten-year intervals, with a spatial resolution of one-eighth degree (7.5 arc-minutes). Such projections are key inputs for analyses of land use, energy use, and emissions and assessments of climate change vulnerability, impacts, and adaptation.

A new article in Frontiers in Climate, “Perspectives on Citizen Science Data Quality,” offers a data lifecycle approach for improving data quality. Senior digital archivist Robert Downs is lead author, with co-authors Hampapuram Ramapriyan, Science Systems and Applications, Inc. (SSAI); Ge Peng, University of Alabama Huntsville; and Yaxing Wei, of the ORNL DAAC.

CIESIN research scientist Susana Adamo and associate director for Science Applications Alex de de Sherbinin are among co-authors of the article, “Food Security among Dryland Pastoralists and Agropastoralists: The Climate, Land-use Change, and Population Dynamics Nexus,” appearing in The Anthropocene Review. Lead author is Illan Stavi, Ben-Gurion University of the Negev, Israel.  Adamo is also one of the guest editors of the Special Issue of the Inter-American Institute for Global Change Research (IAI), “Bridging Science and Policy through Collaborative, Interdisciplinary Global Change Research in the Americas,” in the journal Environmental Development.

The NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN has released several new data sets related to hazards, infant mortality, and future socioeconomic scenarios. The Geocoded Disasters (GDIS) Dataset is a geocoded extension of a selection of natural disasters from the Centre for Research on the Epidemiology of Disaster (CRED) Emergency Events Database (EM-DAT). The data set includes nearly 40,000 locations for almost 10,000 disasters worldwide for the 58-year period spanning 1960–2018. It encompasses all EM-DAT-recorded floods, storms, earthquakes, landslides, droughts, volcanic activity and extreme temperatures, some at administrative level 3 (district/commune/village) but most at 1 (typically state/province/region). GDIS facilitates geospatial analysis of past hazard events.

The Shared Socioeconomic Pathways (SSPs) Literature Database consists of biographic information, abstracts, and analysis of 1,360 articles published 2014–2019 that make substantial use of the SSPs. The database was developed by Carole Green et al. as the basis for a recent article in Nature Climate Change that analyzes use of the Climate Change Scenario Framework and associated scenario data sets in diverse application areas and in assessments of the Intergovernmental Panel on Climate Change (IPCC). The International Committee on New Integrated Climate Change Assessment Scenarios (ICONICS) is planning to extend the literature database. SEDAC User Working Group member Brian O'Neill of the Joint Climate Change Research Institute and CIESIN director Robert Chen are members of ICONICS.

Global Subnational Infant Mortality Rates (IMR), Version 2.01, provides more recent and higher-resolution infant mortality data, including estimates of births and infant deaths. The estimates are for 234 countries and territories, 143 of which include subnational units and are benchmarked to the year 2015 (versus year 2000 for the first version). IMR data are drawn from national offices, Demographic and Health Surveys (DHS), Multiple Indicator Cluster Surveys (MICS), and other sources covering 2006–2014. The birth and infant death data can be aggregated or disaggregated to calculate IMRs at different scales or resolutions. Boundary inputs are derived primarily from the Gridded Population of the World, Version 4 (GPWv4) data collection. National and subnational data are mapped at a spatial resolution of 30 arc-seconds (~1 km at the equator), facilitating integration with demographic, environmental, and other spatial data. Data set development was led by senior geographic information specialist Dara Mendeloff and research scientist Susana Adamo.

The data set, Georeferenced U.S. County-Level Population Projections, Total and by Sex, Race and Age, Based on the SSPs, 2020–2100, contains county-level population projection scenarios of total population, and by age, sex, and race in five-year intervals for all US counties 2020–2100. These data can serve as inputs for addressing questions involving sub-national demographic change in the United States in the near, middle- and long-term. 

Due to the ongoing pandemic, many international conferences have shifted to online, virtual platforms in 2020, opening up opportunities for CIESIN staff to interact remotely with new communities and showcase recent work and new resources.

The paper focuses on case studies in Nigeria, the Democratic Republic of the Congo, and Zambia.

Cascade Tuholske has joined CIESIN for a two-year appointment as an Earth Institute postdoctoral research scientist. Tuholske is a geographer specializing in the integration of global-scale human and environment geospatial data to examine the relationship between urbanization and climate change. At CIESIN, he has begun working with director Robert Chen and associate director for Science Applications Alex de Sherbinin to construct a globally extensive, longitudinal, and fine-scale synthesis of extreme heat events, urban population growth, and the urban heat island effect. His goal is to inform adaptation strategies that reduce the harmful and inequitable impacts of urban exposure to extreme heat. He will also contribute to another NASA-funded project on the use of gridded population and settlement datasets to assess progress towards the United Nations Sustainable Development Goals (SDGs). Tuholske received his PhD in geography from the University of California, Santa Barbara, where he focused on the nexus of climate change, urbanization, and food security in Africa under the guidance of Prof. Kelly Caylor.

The Population-Environment Research Network (PERN) held an online cyberseminar May 18–25 on analysis of the population-climate change-food security nexus. The cyberseminar was moderated by Raya Muttarak of the University of East Anglia and included statements by seven expert panelists from a range of disciplines. A webinar launching the cyberseminar May 18 was led by Alex de Sherbinin, associate director for Science Applications. He and CIESIN research scientist Susana Adamo are co-coordinators of PERN, which is a panel of the International Union for the Scientific Study of Population (IUSSP) and a sustained partner of Future Earth. PERN is supported by the NASA Socioeonomic Data and Applications Center (SEDAC) operated by CIESIN. A YouTube video of the webinar is available online, and background materials from the cyberseminar are posted on the PERN website.

CIESIN scientists have recently published A Living Manual for Climate Information for Adaptation Planning. This online manual is intended for those preparing National Adaptation Plans (NAPs) or specific adaptation interventions, offering guidance in using climate information in the context of adaptation planning. The material was developed as part of a coastal adaptation project in West Africa, the West Africa Biodiversity and Climate Change (WA BiCC) project funded by the U.S. Agency for International Development (USAID). CIESIN has been providing technical assistance to WA BiCC on coastal climate resilience, as part of a team led by Tetra Tech ARD. The Web-based resource is termed a “living manual” since the contents have been updated based on the feedback of participants in a series of country workshops held in the West Africa region. CIESIN associate research scientist Sylwia Trzaska, senior research associate Emilie Schnarr, and associate director for Science Applications Alex de Sherbinin are co-authors.

Senior digital archivist Robert Downs is one of the co-authors of a new paper, “The TRUST Principles for Digital Repositories,″ appearing in the Nature journal Scientific Data. Dawei Lin of the U.S. National Institutes of Health (NIH) is the lead author. The open access paper discusses a set of guiding principles to represent digital repository trustworthiness (transparency, responsibility, user focus, sustainability and technology), developed by stakeholder organizations representing diverse segments of the digital repository community.

The NASA Socioeconomic Data and Applications Center (SEDAC) managed by CIESIN has released several new datasets valuable in assessing future global energy development and land use and in characterizing potential long-term future population distribution in the context of climate change.

One dataset, Global One-Eighth Degree Population Base Year and Projection Grids Based on the SSPs, was developed by Bryan Jones of the City University of New York and Brian O’Neill of the University of Denver. The dataset consists of global urban, rural, and total population data for the base year 2000, and population projections at ten-year intervals for 2010-2100 at a resolution of one-eighth degree (7.5 arc-minutes). These are consistent both quantitatively and qualitatively with the Shared Socioeconomic Pathways (SSPs) that were developed in support of the Intergovernmental Panel on Climate Change (IPCC) assessments. A second dataset, Global 1-km Downscaled Population Base Year and Projection Grids Based on the SSPs, provides a downscaled version of the first dataset, at 1-km resolution (about 30 arc-seconds). This dataset was developed by Jing Gao of the National Center for Atmospheric Research (NCAR). Spatial demographic scenario data are key inputs for the analysis of future land use, energy use, and emission patterns together with potential future climate change impacts, vulnerability, and adaptation.

A third dataset, Global Development Potential Indices (DPI), was developed by James Oakleaf of The Nature Conservancy, and colleagues. This dataset ranks global land suitability in the sectors of renewable energy, fossil fuels, mining, and agriculture, to aid in setting priorities for development and conservation efforts. Each sector-based DPI is a 1-km spatially-explicit, global land suitability map that has been validated using locations of current and planned development.

SEDAC is one of NASA′s Distributed Active Archive Centers (DAACs) in the NASA Earth Observing System Data and Information System. SEDAC seeks to improve access to and use of key socioeconomic and interdisciplinary data that are or can be integrated with remote sensing data. SEDAC datasets have been cited in more than 5,000 different scientific publications during the past 20 years.

Associate director for Science Applications Alex de Sherbinin is a co-author of the open access article, “A Systematic Review of Coastal Vulnerability Mapping,” appearing in the journal Sustainability. The paper, by Anamaria Bukvic of Virginia Polytechnic Institute and State University, Guillaume Rohat of the University of Geneva, Alex Apotsos of Williams College, and de Sherbinin, evaluates the state of coastal vulnerability assessment mapping efforts and recommends improvements in methodological rigor, policy relevance, and alignment with other vulnerability assessment paradigms. The paper stems from previous work supported by the National Socio-Environmental Synthesis Center (SESYNC) under funding received from the National Science Foundation. The paper is dedicated to the memory of second author Rohat, who passed away unexpectedly in October 2019.

Anthony (Tony) Janetos, internationally renowned climate change researcher and director of Boston University's Frederick S. Pardee Center for the Study of the Longer-Range Future, passed away August 6. Janetos had served as a member of the User Working Group (UWG) of the NASA Socioeconomic Data and Applications Center (SEDAC) in 2002–2006. He was a key figure in NASA′s early “Mission to Planet Earth″ program and more recently had a leading role in the U.S. National Climate Assessment. He was a strong proponent of the need for scientific data and policy-relevant indicators to support evidence-based decision making. Prior to joining Boston University, Janetos was head of the Joint Global Change Research Institute at the University of Maryland. He earned his bachelor’s magna cum laude from Harvard University, and his master’s and PhD in biology from Princeton University.

The NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN has begun accepting submissions of scientific data related to human-environment interactions that may be of high utility to the human dimensions research and applications communities. In light of increased recognition of the importance of open access to research data by universities, scientific publishers, funding organizations, and other organizations, SEDAC seeks to increase the accessibility and utilization of important global- or regional-scale spatial data, especially those derived from or complementary to remote sensing data from NASA or other sources. SEDAC will also consider other types of data that meet its acquisition criteria. Priority topics of interest for data acquisition and dissemination include administrative boundaries and other reference layers, population dynamics, human settlements and infrastructure, land use/land cover change, economic development, environmental health, and policy-relevant environmental and sustainable development indicators.

Submission of candidate data sets is a two-step process. In the first step, SEDAC requests basic information on the data (e.g., nature of the data set and its primary purpose) that will help evaluate suitability for SEDAC archiving and dissemination. If the data appear appropriate, a copy of the data will be requested along with additional information for review by the SEDAC User Working Group (UWG). If feasible and appropriate, SEDAC will work with data authors and journal publishers to coordinate data release with publication of a peer-reviewed article. SEDAC will also consider valuable older data sets that may be at risk of loss if not properly archived, as well as national or sub-national data for key countries or regions, on a case-by-case basis.
