The crop simulation models are the effective tools for understanding climate change effects on crop agricultural system (Li et al. 2015; Masutomi et al. 2009). These models have been employed to highlight the climate change impact on crop production and the vulnerability of agro-ecosystem. Several studies have used crop modeling to develop potential strategies to adapt to climate change in the different regions of the world in recent time (Xu et al. 2015; Shrestha et al. 2016; Banerjee et al. 2016; Eitzinger et al. 2017). The modeling studies from Bangladesh (Karim et al. 1996), Japan (Yoshida et al. 2015), China (Shen et al. 2011), Korea (Lee et al. 2012) and India (Krishnan et al. 2007) have been reported the country-specific…show more content…
2011; Lee et al. 2012; Devkota et al. 2013; Wang et al. 2014; Zhang et al. 2015; Kim et al. 2015). Earlier studies have shown that future rice yield projects to decrease in most cases, indicating the effect of the projected increase in CO2 concentration is not outweighed by the effect of the projected increase in temperature. However, there is an uncertainty of future rice production (Webster et al. 2004) using climate change scenarios data from the outputs of General Circulation Model (GCMs) with a coarse resolution to a point-based ORYZA2000 model. This suggests to add fine-scale local climatic information to a coarser one to derive the model (Yao et al. 2007). Although a number of studies have previously been conducted in Bangladesh to investigate the effect of increased temperature and CO2 concentration on rice cultivars (Karim et al. 1994; Mahmood 1998; Mahmood et al. 2004), but less attention has been devoted to modeling studies for rice production (Basak et al. 2010; Karim et al. 2012). Most of the previous studies did not address the effects of climate warming with and without CO2 fertilization under the simulation schemes of different regions in Bangladesh. However, it is yet to find any study which focuses on the regional spatiotemporal yield variations of rice and potential adaptation strategies under future climate change in Bangladesh. Spatiotemporal yield variation studies are essential to identify
