Irrigation cropping pattern zones in Africa which are considered to be homogeneous with respect to crop calendar and cropping
intensity. The delineation of the irrigation cropping pattern zones was done by compiling information of various types:
distribution of irrigated crops, average rainfall trends and patterns, topographic gradients, presence of large river valleys
(Nile, Niger, Senegal), presence of extensive wetlands (the Sudd in Sudan), population pressure, technological differences
and crop calendar above and below the equator.
The dataset consists of the following information: - GIS generated codes (FID, ID); - a code with an unique number to identify
the cropping pattern zone (PATRN_CODE); - a code with the name of the cropping pattern zone (PATRN_NAME); - the cropping
pattern, crop calendar and monthly and yearly cropping intensities for the different zones are described in the on-line
link below (Table 1).
The map with irrigation cropping pattern zones is based on the FAO publication on Irrigation potential in Africa - FAO, 1997.
