Chia-Nan Irrigation Canal System was an important water conservancy construction in the era of the Japanese occupation. It provided a stable water source for paddy irrigation, and the rotational cropping system implemented at that time was an important agricultural management policy.

This article gives a brief introduction to the rotational cropping system and its societal and environmental impacts for the 100th anniversary of the completion of this commemorative project.
