The areas having fully controlled drainage system under surface irrigation in the

Asian Group countries are presented in Figure 10.9. The highest value is 100% in the

Malaysia. In other words, the percentage of areas having fully controlled drainage

system under surface irrigation in Malaysia is close to 100%. The areas having fully

controlled drainage system under surface irrigation in Pakistan is close to 80%.

Considering the total production under drained areas in Asian Group countries,

Suriname has the highest value. This country has 100% total production under drained

areas. Suriname is followed by Pakistan with 70%, Turkmenistan and Uzbekistan with

60% and Tajikistan with 50%.
