Abstract

The hilly areas of southwestern Taiwan is dominated by mudstone. Under normal conditions, these areas have adequate but unevenly distributed rainfall. Many small gullies are found on steep slopes. Mudstone soils are usually shallow and impermeable. Even with abundant, rainfall at times, water shortag problems often occur during dry seasons due to poor water holding capacity. The agricultural water use in these areas is characterized by growing first crop of rice in river valley' and flatland using rainfed. The field-collected rainwater is used to grow a se and crop of rice from June to October. In recent years, increasing number of farm ponds has been constructed to provide water for hill lope orchard farming. Besides irrigation and pest control, purposes the collected water has been used domestically. This paper briefly introduces this water utilization method and its use in a natural setting.
