Abstract
This study evaluated the effects of the rice straw retention project, implemented in Napo-myeon, Gunsan-si, under the payments for ecosystem services (PES) schemes, on providing food for wintering waterfowl. The amount of fallen rice was measured at four sites in both PES and non-PES fields. In all comparison pairs, the count of fallen rice grains in the PES fields was 3-11 times higher than in the non-PES fields (P<0.05). The effect size (r) ranged from 0.386 to 0.790, demonstrating substantial significance. This trend is consistent with similar studies conducted overseas. Therefore, the PES project appears to be achieving its intended goals, and these findings provide a foundation for the scientific evaluation of domestic PES policies.
