Population in Drylands - Percent of Total Population
Listed in NASA Earthdata CMR
The concept of drylands continues to be debated.
Description
In this data set, drylands are taken as areas with a potential hazard of desertification. The hyperarid zone is not subject to desertification and is therefore excluded.
Hence drylands are defined as the arid, semi-arid and dry subhumid zones, or areas with lengths of growing periods of 1-179 days. Global population database from: Tobler, W., U. Deichmann, J. Gottsegen and K. Maloy (1995), The global demography project, Technical Report 95-6, NCGIA, Santa Barbara. The population surface derives from the latest available national census data, which however varied by country from 1979 to 1994.
