Abstract:

The potential is analysed for increasing food supply from the low-yield paddy fields with subsurface irrigation in the alluvial plains of the middle and lower reaches of the main rivers of South China. The paper describes techniques for improving agricultural water management aimed at increasing water and land productivity in rice-based systems, and suggests policies and incentives for water savings in rice-based systems. The improvement of rice yields, and increases of multiple cropping index in rice-based systems, in South China would play an important role in increasing food production capacity and changing the situation of "grain transfer from north to south", and in reducing water demand in the North.
