Redeploying farming water supplies

By Yu Gwo-Hsing 虞國興

In addition, water used for agricultural irrigation that seeps into the ground replenishes groundwater with as much as 2 billion cubic meters each year. In addition to increasing the efficiency of water resources circulation, it can reduce the threat of ground subsidence.

Agricultural self-sufficiency provides a stable basis for a nation and its society, and farm hydrology not only aids farming but is also a form of green industry that improves water flow and flood prevention. The Food and Agriculture Organization has repeatedly called on member states to pay attention to the development of agricultural hydrology. Taiwan currently has a water resources usage ratio of only about 20 percent, leaving much room for development.

We should also be able to provide water to private and industrial users, as it is not appropriate that they should compete for cheap water intended for farming. By taking these actions, we can avoid impacting the nation’s overall sustainable development.

Yu Gwo-hsing is vice president of Tamkang University and director of the university’s Water Resources Management and Policy Research Center.
