Abstract

Alternate Wetting and Drying (AWD) offers considerable potential to reduce water use and methane emissions in irrigated rice systems without compromising yields. However, despite decades of promotion, AWD adoption remains limited, especially in gravity-fed irrigation systems where institutional and agro-environmental complexities pose challenges to implementation.
