Potential for Rice Production in South Africa given Water Constraintsby Prof Lanier Nalley

As water becomes scarcer in rice production regions throughout the world, producers are becoming aware of the importance of increasing water-use efficiency. Thus, new rice production methods which increase water-use efficiency are beginning to be adopted. Alternate wetting and drying (AWD) irrigation has the potential to address the growing concerns of groundwater depletion as well as greenhouse gas emissions (GHG) associated with rice production.
