Abstract

This paper examined how alternate-wetting and drying (AWD), a water saving technology, affected the economic aspect of lowland rice farming in Bohol [Philippines]. AWD was introduced in the Bohol Irrigation System (BIS) 1 in 2006. The changes in the area cultivated, yield, and mean net income of rice farmers were assessed using household panel data for 2005 and 2010. Descriptive statistics, comparison of means, and regression models were used to characterize the changes between the two periods. The mean and total rice areas cultivated were higher in 2010 compared to 2005. There were significant increases in the mean yield and net income of farmers, especially among those from the downstream areas. Regression analyses indicated that AWD might have had a significant contribution to changes in profit but not to yield. It was further confirmed that AWD did not cause yield penalty. Farmers, particularly those from the downstream areas, had a more reliable water supply after AWD implementation, resulting in a closing of the yield gap between upstream and downstream farmers.
