Zusammenfassung |
A new version of a digital global map of irrigation areas was developed by
combining irrigation statistics for 10 825 sub-national statistical units
and geo-spatial information on the location and extent of irrigation
schemes. The map shows the percentage of each 5 arc minute by 5 arc minute
cell that was equipped for irrigation around the year 2000. It is thus an
important data set for global studies related to water and land use. This
paper describes the data set and the mapping methodology and gives, for the
first time, an estimate of the map quality at the scale of countries, world
regions and the globe. Two indicators of map quality were developed for this
purpose, and the map was compared to irrigated areas as derived from two
remote sensing based global land cover inventories. |
