Bangladesh is the seventh largest rice producers in the world. Almost the whole quantity of rice produced is consumed within the country. Rice is deeply rooted to the food habit of Bangladeshis. From this necessity Bangladesh needs to take early steps for combating the effect of global climate change on rice production. The climate-yield relationship in rice production is analysed using A1B, A2, and B1 scenarios. Rice yields of the three varieties, Aus, Aman, and Boro is projected using average annual historical growth rate with climate parameters, such as CO2 concentration, temperature, and rainfall. The projected growth in yield which is calculated by historical growth rate is compared with the growth of yield projected in three SRES scenarios. The three rice models are projected up to the year of 2080, starting from 2011. The software Vensim is used for the simulation. In this study it is found that "Boro" is the most affected variety in the changing scenarios of climate. For improving the production of rice, Bangladesh needs to strengthen institutional capacity and research towards climate resilient cultivars, develop climate resilient production technologies, and disseminate information to growers about weather forecasts through early warning systems.
