to Develope a Geo-Referenced Database of Irrigation Areas
in the Nile Basin
technical workshops are scheduled, from 12 to 16 February
and 26 February to 2 March 2007 respectively, at the project
office in Entebbe to improve the database and GIS layer
of existing areas under irrigation in the Nile Basin.
project has invited two participants each per Nile country.
The event will be facilitated by Mrs. Wageye Teshome, Dr.
Stephen Ngigi, and Mr. Arjen Rotmans.
In view of the importance of irrigation in the Nile water
balance, special attention is given to the development and
validation of a detailed irrigation map. The data set will
include the actual geographic locations of the irrigated
areas, as well as a set of basic descriptors that qualify
the irrigation schemes. This includes crop, type of water
control, area equipped for irrigation, area effectively
databases will be compared with international datasets and
satellite imagery. These include FAO – Frankfurt GIAM,
Aquastat, FAOstat, Africover, and Landsat. Particular attention
will be given to using the MODIS space-greening tool developed
by the project to estimate the extent of land equipped for
irrigation that is effectively irrigated.
