salinization demonstrates difference from one country to another. For example, it is
close to 85% for the soils of Kuwait. At the same time, it is salinized of full control
irrigation in the 50% of Iraq, 40% Libya, 33% Bahrain, 28% Sudan and 23% Tunisia.
The areas having fully controlled drainage system under surface irrigation in the
Arab Group countries are presented in Figure 10.6. The highest value is 90% and is in
Tunisia. In other words, the percentage of areas having fully controlled drainage system
under surface irrigation in Tunisia is close to 90%. This figure for Jordan, Morocco and
Syria is 75%, 50% and 30% respectively. Considering the total production under
drained areas in Arab Group countries, Egypt has the highest value with 85%.
