Wetting & Drying (AWD) Short Duration Variety (SDV) Net emissions reductions and carbon sequestration Total Annual tCO2e AAPI Bangladesh Promoted UDP with adoption anticipated on 1.8 million ha of rice. Emission reductions due to decrease in fertilizer and loses of nitrogen through volatilization, surface runoff, or leaching of nitrate. HARVEST Cambodia Introduced SDV rice to an estimated 76,893 ha in the project area. This rice variety reduces the total duration of cropland flooding and emission of methane. Galford et al. In Prep.

Specifically, the project supported soil and water conservation measures, enclosures of degraded pastures, and selective bush tinning. Promoted both livestock management practices that significantly increased productivity per livestock animal. Due to these interventions, the project predicted an overall decrease in the size of the animal herd. Galford et al. In Prep. Interventions Analysis– Livestock
