Global Earthquake Hazard Distribution - Peak Ground Acceleration

&
The Global Earthquake Hazard Distribution-peak ground acceleration is a 2.5 minute grid of global earthquake hazards developed using Global Seismic Hazard Program (GSHAP) data that incorporate expert opinion in predicting localities where there exists a 10 percent chance of exceeding a peak ground acceleration (pga) of 2 meters per second per second (approximately one-fifth of surface gravitational acceleration) in a 50 year time span. For the purpose of identifying hazard hotspots, values of 2 meters...

P. Potter, N. Ramankutty, E.M. Bennett & S.D. Donner
The Nitrogen Fertilizer Application data set of the Global Fertilizer and Manure, Version 1 Data Collection represents the amount of nitrogen fertilizer nutrients applied to croplands. The national-level nitrogen fertilizer application rates for crops are from the International Fertilizer Industry Association (IFA) "Fertilizer Use by Crop 2002" statistics database that is available by request from the Food and Agriculture Organization (FAO). The number of crop-specific fertilizer application rates reported for each country ranged from 2...

Global Flood Hazard Frequency and Distribution

&
The Global Flood Hazard Frequency and Distribution is a 2.5 minute grid derived from a global listing of extreme flood events between 1985 and 2003 (poor or missing data in the early/mid 1990s) compiled by Dartmouth Flood Observatory and georeferenced to the nearest degree. The resultant flood frequency grid was then classified into 10 classes of approximately equal number of grid cells. The greater the grid cell value in the final data set, the higher...

Global Landslide Hazard Distribution

, &
The Global Landslide Hazard Distribution is a 2.5 minute grid of global landslide and snow avalanche hazards based upon work of the Norwegian Geotechnical Institute (NGI). The hazards mapping of NGI incorporates a range of data including slope, soil, soil moisture conditions, precipitation, seismicity, and temperature. Shuttle Radar Topography Mission (SRTM) elevation data at 30 seconds resolution are also incorporated. Hazards values 4 and below are considered negligible and only values 5 through 9 are...

Global Multihazard Mortality Risks and Distribution

, &
The Global Multihazard Mortality Risks and Distribution is a 2.5 minute grid identifying and characterizing the nature of multihazard risk at the global scale. For this study, multihazard considers the hazards posed by cyclones, droughts, earthquakes, floods, landslides and volcanoes. The specific hazards are grouped into the following hazard categories: drought (drought), seismic (earthquakes and volcanoes), and hydro (cyclones, floods, and landslides). Each grid cell is assessed for each hazard category; and is considered at...

Global Rural-Urban Mapping Project, Version 1 (GRUMPv1): Population Density Grid

, , &
The Global Rural-Urban Mapping Project, Version 1 (GRUMPv1) consists of estimates of human population for the years 1990, 1995, and 2000 by 30 arc-second (1km) grid. The population density grids measure population per square km. A proportional allocation gridding algorithm, utilizing more than 1,000,000 national and sub-national geographic units, is used to assign population values to grid cells. The population count grids are divided by the land area grid to produce population densities. This data...

In addition to population counts and variables, the centroids have associated administrative unit names and the land area of contained within the administrative unit. GPWv3 is produced by...

Gridded Population of the World, Version 3 (GPWv3): Population Density Grid, Future Estimates

&
The Gridded Population of the World, Version 3 (GPWv3), Future Estimates consists of estimates of human population for the years 2005, 2010, and 2015 by 2.5 arc-minute grid cells. A proportional allocation gridding algorithm, utilizing more than 300,000 national and sub-national administrative units, is used to assign population values to grid cells. The future estimate population values are extrapolated based on a combination of subnational growth rates from census dates and national growth rates from...

Millennium Ecosystem Assessment: MA Population

The Millennium Ecosystem Assessment: MA Population data sets provide baseline population information as one of the drivers of ecosystem change. The data helped in estimating the magnitude of regional pressures on ecosystems. The MA Population data sets include Gridded Population of the World (GPW) version 3, population grids from the Global Rural-Urban Mapping Project (GRUMP) (alpha version), Global Subnational Infant Mortality Rates (alpha version), and Global Subnational Prevalence of Child Malnutrition (alpha version) data.

HANPP Collection: Human Appropriation of Net Primary Productivity (HANPP) by Country and Product

M.L. Imhoff, L. Bounoua, T. Ricketts, C. Loucks, R. Harriss & W.T. Lawrence
The Human Appropriation of Net Primary Productivity (HANPP) by Country and Product portion of the HANPP Collection contains tabular data on carbon-equivalents of consumption by country and by type of product. The data were compiled from national-level FAO statistics on consumption of products such as vegetables, meat, paper, and wood. HANPP represents the amount of carbon required to derive food and fibre products consumed by humans including organic matter that is lost during harvesting and...

Global Agricultural Lands: Croplands, 2000

2001 Environmental Sustainability Index (ESI)

, &
The 2001 Environmental Sustainability Index (ESI) utilizes a refined methodology based on the 2000 Pilot ESI effort, to construct an index covering 122 countries that measures the overall progress towards environmental sustainability. The index is a composite measure of the current status of a nation's environmental systems, pressures on those systems, human vulnerability to environmental change, national capacity to respond, and contributions to global environmental stewardship. The refinements included the addition and deletion of indicators,...

Global Cyclone Hazard Frequency and Distribution

, , &
The Global Cyclone Hazard Frequency and Distribution is a 2.5 minute grid based on more than 1,600 storm tracks for the period 1 January 1980 through 31 December 2000 for the Atlantic, Pacific, and Indian Oceans that were assembled and modeled at UNEP/GRID-Geneva PreView.
