Description :
Focusing on the spatial distribution of seasonal drought with rice and the practices to adapt to it, and based on an analysis of balanced water supply for and demand by rice at a growing season scale during 1981–2030, this paper assesses the changing seasonal drought in the process of rice production under the changing climate in the future, and identifies general rice re-cultivation options for climate change adaptation. It is indicated that due to climate change, seasonal drought in major rice producing areas tends to alleviate in general, late season rice in particular. Future climate change brings about a significant impact on the spatial/temporal distribution of water resources in rice producing areas in China. Based on pre-designed adaptation actions for rice-re-cultivation, the rice cultivation pattern undergoes a significant alteration between 1981–2000 and 2001–2030.
