The rice irrigation systems of Kazakhstan are situated mostly in the basins of the rivers Syr Darya, lli, and Karatal. The rice fields cover more than 103 000 ha. In 1992, the average yield was 4.7 tons/ha. An increase in rice production depends on the modernization of existing irrigation systems, the reclamation of soil in the irrigated areas, and the rational utilization of water resources to protect them from pollution and over-exploitation.
