Chapter synopsis: Rice land receives 35–45% of all the world’s irrigation water. In view of growing concerns about future water scarcity, achieving water savings in irrigated rice production has become a key research challenge. This chapter considers the key techniques for improving rice water productivity through enhanced irrigation practices aiming to reduce irrigation water use in rice cultivation. These include the cultivation of aerobic rice, the use of the Alternate Wetting and Drying (AWD) technique, and the deployment of Ssaturated Ssoil Cculture. The chapter includes a detailed case study of water savings management in rice cultivation in southeast Australia and suggests possible lines for future research.
