As one of the most important crops in China, rice accounts for 18% of the country’s total cultivated area.
Increasing atmospheric CO2 concentration and associated climate change may greatly affect the rice productivity. Therefore, understanding the impacts of climate change on rice production is of great significance. This paper aims to examine the potential impacts of future climate change on the rice yield in
the middle and lower reaches of the Yangtze River, which is one of the most important food production
regions in China. Climate data generated by the regional climate Model PRECIS for the baseline (1961–
1990) and future (2021–2050) period under IPCC SRES B2 scenario were employed as the input of the rice
crop model ORYZA2000. Four experimental schemes were carried out to evaluate the effects of future
climate warming, CO2 fertilization and water managements (i.e., irrigation and rain-fed) on rice production.
The results indicated that the average rice growth duration would be shortened by 4 days and the
average rice yield would be declined by more than 14% as mean temperature raised by 1.5 C during the
rice growing season in 2021–2050 period under B2 scenario....
