Visualizing the Global Extent of Cropland and Pastures Food: An Atlas The SEDAC Global Agricultural Cropland and Pasture data sets are presented in Food: An Atlas, which uses maps to explore global food distribution and production. The cropland and pasture data, originally developed by Ramankutty et al (2008), are transformed into cartograms, in which the land area of countries is replaced by extent of crops and pastures, by Benjamin Hennig to better visualize the magnitude of agricultural areas around the world.		Changing Global Patterns of Urban Exposure to Flood and Drought Hazards Global Environmental Change Combining SEDAC’s Low Elevation Coastal Zone (LECZ) data and Natural Disaster Hotspots flood frequency maps with land cover imagery derived from NASA’s MODIS instrument, the researchers who developed SEDAC’s Global Grid of Probabilities of Urban Expansion data set ask how the global and regional patterns of urban growth in the near future will affect urban susceptibility to floods and droughts. What they found is that the extent of urban areas exposed to floods and drought will generally double by 2030, even without factoring in the potential impacts of climate change.
