Rice Simulation And Climate Change

Crop simulation model is an effective tools in understanding climate change effects on agricultural production systems (Masutomi et al. 2009; White et al. 2011). The modeling studies from Bangladesh (Karim et al. 1996), Japan (Horie et al. 2000), China (Shen et al. 2010), Korea (Lee et al. 2012) and India (Krishnan et al. 2007) reported the country-specific discrepancies in future rice yield due to climate warming; the highest decrease in rice yield will probably occur in most areas of low latitude (Krishnan et al. 2011), whereas increase in rice yield may occur in some area of high latitudes (Rosenzweig et al. 2014). Nevertheless, spatial and temporal changes in rice yield are quantified by the modeling studies with fixed cropping patterns over the continuum of future climate change. …show more content…
2001) has been employed to simulate the rice yield response to climate change. Compared with other rice simulation models like CERES, DSSAT crop models, ORYZA2000 provides the most consistent rice yield prediction with uncertainties in comparison to the variation of field observation (Li et al. 2015). Similar to other models, a site specific parameterization of crop management practices and rice cultivars of the model will improve confidence in simulation. It can simulate precisely the response of rice yield to climatic variability in various climatic regions equally good or even better than other rice crop models (Zhang and Tao 2013). A significant number of ORYZA2000 model studies under different scenarios on the impacts of climate change on rice production have been well documented in the recent literature (Shen et al. 2011; Lee et al. 2012; Devkota et al. 2013; Wang et al. 2014; Zhang et al. 2015; Sumathi et al. 2015; Kim et
