A Closer Look at RIPE100’s Qualifying Practices: Alternate Wetting and Drying for Rice
RIPE’s researchers continually work to expand the set of practices that would qualify for $100 per unit payment under the proposed RIPE100 program by collecting research that demonstrates the combined environmental value of climate-smart practices. This month, we’re highlighting alternate wetting and drying (AWD) for rice. Compared to continuous or winter flooding, AWD reduces emissions and provides additional environmental benefits valued at $100 per acre per year.
We found that farmers who adopt AWD reduce greenhouse gas emissions by nearly 2 metric tons per acre for a public value of $39 per acre. This is a large amount of GHG savings per acre! And yet the practice does so much more for the environment that doesn’t get captured in that GHG value alone. This practice also provides over $40 per acre in water savings and $19 per acre in water quality benefits.
