Climate, Health and Land Cover/Land Use Interactions in Kenya
Researchers: Deborah Balk, CIESIN; Chris Small, Lamont Doherty Earth Observatory; Dan Kammen, UC-Berkeley; Majid Ezzati, WHO
Abstract: This study addresses the following questions: (1) To what extent are the transmissions of various diseases in Kenya subject to climate variations? (2) To which climate or land cover parameter is each disease most responsive? (3) How much of the variability in each disease’s response to climate or land cover change is related to the interactions between the diseases? This study includes multiple methodologies from the earth and social sciences appropriate for the analysis of remotely-sensed, climate, clinic, and population data. The research team has assembled an integrated, georeferenced database comprised of a ten-year record for multiple diseases (e.g., malaria, acute respiratory infection, anemia, diarrheal diseases, intestinal parasites, malnutrition, schistosomiasis, urinary tract infections) from clinic records, for multiple clinics in Laikipia District, Kenya. These are linked with (daily and) monthly rainfall data from meteorological stations, and with Landsat imagery (from 1987).

Researchers: Malanding Jaiteh (PI), Linda Pistolesi, Olena Borkovska, Alyssa Fico, and John Squires
Abstract: The goal of the project is to provide a GIS-based decision support tool for the Hudson River Restoration Project (HRRP) partners. CIESIN’s geospatial team has compiled a comprehensive geospatial data directory of 200 GIS data sets relevant to the Hudson River basin across all ten counties bordering the Hudson and has developed a physical habitat model of the river floor. The habit units are based on bathymetry depth, slope, sediment morphology and sediment environment. The habitat units are being characterized and ranked based on a set of biotic, abiotic and anthropogenic drivers, stressors, and states in the context of a selection of target ecosystem characteristics. The results of the assessment will assist Hudson River Restoration Project (HRRP) partners in identifying and prioritizing habitat units for preservation or restoration.

GIS-based Assessment of Undeveloped Parcels in New York Coastal Counties
Researchers: Yuri Gorokhovich (PI)
Abstract: Existing parcel data from coastal counties of New York State was assembled to be used by LISS and NYSDEC officials in conservation of the most significant remaining unprotected and undeveloped parcels. The developed methodology evaluated undeveloped coastal parcel data in numerical ways to identify a score that will be used in the final analysis of categorizing undeveloped coastal parcels according to their conservation values. Part of the data set related to Westchester County is hosted on an Internet mapping server together with similar data from the project Hudson River Communities Vacant Property Inventory, thus increasing the value and outcome of the project.The developed methodology of the GIS-based assessment and compiled database was meant to help NYSDEC improve their coastal management and assessment practices. Preservation of undeveloped parcels within New York’s watershed area of Long Island Sound promotes conservation of open space, landscapes and ecosystems; improves access to the Sound; prioritizes property types for natural resources conservation and reduces the amount of non-point source pollution reaching Long Island Sound.

Emerging Infectious Disease Modeling
Researchers: Marc Levy (co-PI), CIESIN
Abstract: CIESIN is working with the Consortium for Conservation Medicine on a project aimed at developing spatial models capable of explaining and predicting patterns of emerging infectious disease outbreaks. This project constitutes a follow-up to earlier work that culminated in a 2008 publication in the journal Nature explaining how hotspots of emerging infectious disease risk could be identified and mapped. The work is based on the premise that new disease patterns may not resemble those of the past, and that only by explicitly modeling the interaction of multiple drivers and human-environment systems can we understand how patterns are likely to change.

A Multidisciplinary Approach to Evaluating Missing Data When Relying on Participatory Reports of Unusual Events
Center for International Earth Science Information Network (CIESIN)
Researchers: Ilana Brito, Earth Institute Fellow (PI); Susana Adamo (co-PI); Tiffany Bogich, EcoHealth Alliance (formerly Wildlife Trust)
Abstract: The project, applicable across many topics and disciplines, addresses the fundamental importance of distinguishing between true differences in occurrence and differences resulting from possible biases in reporting of events. The research will focus on four areas where case reporting is important for policy development: invasive species outbreaks, crimes and accidents, forest fires and small-scale natural disasters, and emerging infectious disease events. A key objective is to create a general framework for identifying and quantifying bias in participatory reporting. This research has obvious implications for other topics which include developing “true” maps of the spatial distribution of product recalls, conservation successes, energy usage, impacts of climate change, car accidents, drug trafficking and patterns of migration.

A Spatial Analysis of Childhood Mortality in West Africa
Researchers: Deborah Balk, Adam Storeygard, and Melissa Newman, CIESIN; Tom Pullum, University of Texas; Fern Greenwell, ORC-Macro
Abstract: It has been suggested that environmental or geographic factors—e.g., population density, climate, and disease environment—play an important role in determining infant and child survival above and beyond that played by individual and household level factors. Only recently, however, have relevant spatial data become available and have demographic survey data systematically recorded geographical location of surveyed households, while at the same time the technology to integrate these data has become accessible. This study estimated the risk of infant and child death attributable to individual, household, and spatially explicit geographic factors, in ten West African countries; 120,000 births occurring in the ten years prior to 1997–2001 Demographic and Health Survey dates are evaluated. Results from a generalized linear model showed that spatial variables explain away a good deal of the country-specific variation in mortality and that they are associated with (and may be mediated by) the household characteristics. Implications for research and policy have also been addressed.
Funder: Financial support for this project was provided by ORC Macro under the USAID-funded MEASURE DHS+ program. The research was also facilitated by complementary activities underway at CIESIN funded by the NASA Socioeconomic Data and Application Center (Contract NAS 5-98162) and the UN Millennium Development Project.

Hydrology and Social Interactions: A Focus on Conflict in Africa
Researchers: Marc Levy (PI) and Christian Webersik, CIESIN
Abstract: Does climatic and hydrologic variability influence patterns of civil war outbreak? Using data for Africa, and controlling for social, economic, and political factors, this project (1) tested hypotheses linking water scarcity and variability to civil war outbreak, ceteris paribus, (2) in order to develop and test a methodology for combining gridded environmental time series data with spatial time series conflict data, (3) to communicate the findings and implications to decision-makers, and (4) to produce a data collection useful to a wide range of scholars of civil war, human security, and other fields who are interested in the impacts of water scarcity on human wellbeing and behavior. The uniquely interdisciplinary research team was composed of hydrologists, political scientists and geographers, aiming to generate a set of country-level and subnational-level water indicators useful to a range of social science research needs, including public health, economic development, demography, and land use/land cover change. The project aimed for broader impact as well, with vital policy implications in fields such as early warning, humanitarian assistance, and development planning.

Revitalizing Urban Population Projections: New Data, New Methods
Researchers: Deborah L. Balk (PI), Baruch College-City University (formerly of CIESIN); Christopher Small, Lamont Doherty Earth Observatory; Mark Montgomery, Population Council; Thomas Buettner, UN Population Division
Abstract: As the developing world continues to urbanize, and Africa and Asia approach the point at which they will become more urban than rural, new investments in demographic data and research methods will be required to understand and address the needs of urban residents. At a minimum, policy makers will need defensible estimates of city population sizes, rates of growth, and geographic extents if they are to formulate effective development strategies. At present the demographic research community cannot supply such estimates. The goal of the proposed research team is to produce and evaluate new spatially-explicit demographic methods for estimating and projecting city populations in the developing world. The essence of our approach is to merge several important sources of information that have yet to figure into city estimates and projections for developing countries: spatially-coded information (such as urban spatial extents, derived from satellite data [CIESIN et al., 2005] and administrative areas); and survey data on urban fertility, child mortality, migration, and age structure (as provided by the World Fertility Surveys (WFS), the Demographic and Health Surveys (DHS), and the Multiple Indicator Cluster Surveys (MICS)), along with the census data that are the basis of current estimates.

Researchers: Deborah Balk, Baruch College-City University (formerly of CIESIN); Uwe Deichmann, the World
Bank; Stanley Wood, International Food Policy Research Institute
Abstract: There are increasing demands for greater
specificity in defining the impacts of agricultural research and
development, particularly with regard to the likely impacts on poverty of
policy, technology, and institutional changes. The
development of spatially disaggregated global population databases
represents a significant contribution to meeting those demands.
However, most means of assessing the economic consequences of
change in the agricultural sector involve the identification of
impacts on producers, predominantly located in rural areas, and
consumers, increasingly represented by urban populations in many
countries. Notwithstanding the important challenge of properly
characterizing combined production and consumption patterns in
rural households, a major step forward in impact assessment would
be the spatial delineation of human settlements and rural and
urban populations. The purpose of this research is to produce
a gridded urban-rural data set, with each pixel representing not
only population size and density, but also urban or rural character.

New Methods for Understanding Intra-Urban Contours at a Global Scale
Researchers: Deborah Balk (PI), Baruch College-City University (formerly of CIESIN); Ernesto Rodriguez and Son V. Nghiem, California Institute of Technology; Christopher Small, Lamont Doherty Earth Observatory
Abstract: A global and consistent characterization of land use and land change in urban and suburban environments is crucial for many fundamental social and economic science studies and applications. Here, a dense sampling method (DSM) using satellite scatterometer data at a coarse resolution (~12 km) to delineate urban and intra-urban areas at a much higher resolution (~1 km) was presented for the first time. The tradeoff is that the daily or near daily temporal resolution is reduced to yearly or multi-year time scale, which is still appropriate to map urban areas and to identify interannual changes in most cases. The DSM results were analyzed together with information on population and housing censuses, with Spectral Mixture Analysis (SMA) of moderate and high spatial resolution optical satellite imagery, and with both DMSP night lights.

Woolmer, the Wildlife Conservation Society (WCS)
Abstract: To inform the priority setting discussion
of where to focus limited conservation resources, WCS and CIESIN
conducted a globally extensive GIS analysis of the most recent
appropriate publicly available global digital datasets to locate
the remaining wild areas in the world. Previous attempts to map
wilderness areas used older data or data covering a lesser extent.
Our analysis first defined what is “not wild” using
information on land cover, population density, stable lights and
human infrastructure, thus creating an inverse map of the potential
wild areas. Second, these wild areas are placed in a relative context
by normalizing them with respect to different biomes on each continent.
Finally, results are checked with conservation biologists from
the WCS international conservation programs and other data to
verify our mapping. The resulting map can be used as a conservation
reconnaissance tool, for strategic planning of conservation investments,
and for other global analyses.

Abstract: A multi-disciplinary/multi-scale approach
to evaluating how changes in demography and land use are affecting natural and human systems at the continental, country, and municipality scales in Latin America and the Caribbean.
We will explore how land use patterns are affected by demographic, economic,
and ecological factors. We expect to identify
two major patterns: 1) extensive conversion of natural ecosystems to modern agriculture, particularly in
areas with little topographic relief, and 2) abandonment of marginal agricultural and grazing lands,
particularly in mountainous and remote regions, permitting ecosystem recovery. We anticipate that this
dual trend will be most evident in countries and regions further along the demographic and economic
transition axes, while developing nations and regions lagging in these transitions will experience
relatively less intensification of lands through modern farming techniques and relatively more continued conversion of mountainous regions and remote frontiers.

Unfortunately, data on buildings and other structures, and especially their vulnerability to earthquake damage, are incomplete and variable in quality. As an element of the Global Earthquake Model (GEM), an international initiative to improve assessment and decision making regarding earthquake risk, CIESIN is participating in a new three-year project to develop a comprehensive Global Exposure Database, led by the University of Pavia in Italy. CIESIN is leading the design of the underlying database and supporting the interoperability of the database with other GEM components. Another CIESIN role is to help populate the database, drawing on its extensive population and other spatial data resources and longstanding expertise in this area.
Global Natural Disaster Hotspots
Researchers: Maxx Dilley and Bradfield Lyon, International Research Institute for Climate Prediction; Robert S. Chen and Gregory Yetman, CIESIN; Uwe Deichmann and Piet Buys, Development Economics Research Group, the World Bank; Arthur Lerner-Lam, Center for Hazards and Risk Research and Lamont-Doherty Earth Observatory; Margaret Arnold and Jonathan Agwe, Hazard Management Unit, the World Bank; Oddvar Kjekstad, International Centre for Geohazards, Norwegian Geotechnical Institute
This project assessed the global risks of two disaster-related outcomes: mortality and economic losses. We estimated risk levels by combining hazard exposure with historical vulnerability for two indicators of elements at risk—gridded population and Gross Domestic Product (GDP) per unit area—for six major natural hazards: earthquakes, volcanoes, landslides, floods, drought, and cyclones. By calculating relative risks for each grid cell rather than for countries as a whole, we estimated risk levels at subnational scales. Such information can inform a range of disaster prevention and preparedness measures, including prioritization of resources, targeting of more localized and detailed risk assessments, implementation of risk-based disaster management and emergency response strategies, and development of long-term land-use plans and multihazard risk management strategies. A set of accompanying case studies, available separately, explored in more detail risks from particular hazards or for localized areas using the same theoretical framework as the global analysis.

Social and Environmental Vulnerability Disasters
Researchers: Gilbert Burnham (PI), John Hopkins School of Public Health; Yuri Gorokhovich (Co-PI), CIESIN; Courtland Robinson (Co-PI), Shannon Doocy (Co-PI)
Abstract: There is a growing awareness of the need for better measurements and models of vulnerability to natural disasters and for improved management of information that guides the humanitarian response. A collaboration between the Center for Refugee and Disaster Response at the Johns Hopkins School of Public Health and CIESIN will bring together the fields of physical science, demography, public health, and informatics in order to develop an integrated approach to disaster assessment that will enhance the understanding of vulnerability and provide information for decision making in the post-disaster context. The research will develop the means by which spatial dependencies and interactions between population and environmental variables can be described and studied using GIS models, available socio-demographic information, and data from field surveys of disaster-affected areas with the dual objectives of assessing the risk of populations to natural disasters, and providing information on affected populations to decision makers in the post-disaster relief and rehabilitation environment. In terms of the broader results of the research—modeling population vulnerability and risk in natural disasters—it is intended that those models will be used to inform post-disaster assessments of surviving populations by presenting clear visual representations of disaster risk and impact on populations, enabling governments and humanitarian organizations to better locate need and allocate resources in the aftermath of disasters.

Circular Migration and Its Long-Term Consequences
Researchers: Ronald Rindfuss (PI), University of North Carolina; Susana Adamo (co-PI), CIESIN
Abstract: Migration is an important coping strategy for poor populations faced with uncertain incomes based on agriculture. Building upon theoretical and empirical advances in migration research, CIESIN collaborated with scientists at the University of North Carolina at Chapel Hill on a research project on migration patterns in the Nang Rong district of northeast Thailand. This rural area is marginal in terms of poor quality soils, inadequate rainfall, and few non-agricultural jobs. Bangkok, the capital city, and the eastern seaboard, a government-supported development zone, are the principal urban destinations. The project used life-history data to examine the likelihood of migrating away from rural villages and other migration patterns. It attempted to assess what determines different migration strategies and how early migration experience may affect an adult’s place of residence at age 30.

Abstract: The Global Poverty Mapping Project characterized the global distribution of poverty and tested the
proposition that the world’s poor live under geographic
and biophysical conditions significantly different from
those experienced by other populations. The project used GIS
analysis to characterize the nature of those conditions. Spatial
statistical methods were also tested for their effectiveness
in analyzing global spatial poverty data. The project resulted
in a global spatial database of poverty variables with high resolution
data for approximately 26 countries. Web site ongoing.

Urban Remote Sensing and Slum Mapping
Researchers: UNHABITAT, the International Institute for Geo-Information Science and Earth Observation (ITC) in the Netherlands, and CIESIN
An exploration of methods to produced and evaluate new spatially explicit demographic methods for estimating and projecting city populations in the developing world to fill the current gap in the demographic research commiunity. To understand and address the needs of urban residents, and to formulate effective development strategies, policymakeres will need defensible estimates of city population sizes, rates of growth and geographic extents. Remote sensing imagery for mapping of urban slums, as part of ongoing slum mapping effics is one specific initiative to estimate population in regions where data are difficult to gather.

This project focused on the utilization of satellite remote sensing data to improve the effectiveness of ecosystem-oriented multilateral environmental agreements (MEAs). These agreements include, among others, the Convention on Biological Diversity, the World Heritage Convention, the Ramsar Convention on Wetlands of International Importance, and UNESCO Biosphere Reserves. These conventions and site designations serve to protect natural resources and biodiversity of international importance, yet they are often constrained by lack of data and information to support implementation. The project tested applications of remote sensing at a Ramsar and Biosphere Reserve site in northeastern Uruguay (Banados del Este), and in the adjacent transboundary freshwater lake (Laguna Merin, shared by Uruguay and Brazil) that is threatened by land use practices, agrochemical pollution, and over-fishing.

Recent projects include a Gates Foundation AGCommons grant to map Ethiopian roads using a customized Personal Digital Assistant (PDA) interface (in collaboration with World Food Program field staff), and a NASA-SERVIR funded project to develop roads data from ASTER satellite imagery. The first phase product, the Global Roads Open Access Data Set (gROADS), were released in 2011. A new version, Global Roads Open Access Data Set, Version 1 (gROADSv1), was released May 2013.
Roads Data Development for Ethiopia
Researchers: Alex de Sherbinin (PI) and Greg Yetman, CIESIN; Olivier Cottray, IMMAP; Tesfaye Korme and Erick Khamala, Regional Centre for Mapping of Resources for Development (RCMRD)
CIESIN together with IMMAP and RCMRD used GPS-enabled PDA technology to collect data compliant with a United Nations spatial data model (the UNSDI-Transport model). The tool was employed along all-weather roads in Ethiopia as well as along major dry-season link roads to collect road location and attribute information. Location information was also collected for the following infrastructure of importance to small holder farmers: irrigation equipment, water reservoirs, markets, community grain storage or fertilizer warehouses, and agricultural extension offices.

Environmental Performance Index
Researchers: Marc Levy, Alex de Sherbinin, Malanding Jaiteh, Tricia Chai-Onn, and Valentina Mara, CIESIN, in partnership with researchers at the Yale Center for Environmental Law and Policy
The Environmental Performance Index measures environmental performance at the country level for issue areas using a proximity-to-target methodology. Targets for each issue area such as urban particulate matter concentrations, access to water and sanitation, nitrogen concentrations in water, and timber harvest rates were identified in international consensus documents or by consulting the scientific literature. Country performance is measured as a proximity to the internationally recognized targets.
