Extra information:


This study focuses on quantifying the changes in water requirements of dry season Boro rice under recent and future climate changes. This study also assessed the effectiveness of shifting trans-/planting date of Boro rice to adapt to climate change and prioritized adaptation options in Northwest Bangladesh. The CropWat model was used to quantify changes in water requirements for recent decades and future scenarios (for RCP 4.5 and 8.5 in 2050s and 2080s). The growing degree days method was followed to quantify changes in growth duration of rice. Future water requirements of Boro rice for early, normal and late planting and possibilities of high temperature stress during critical periods were assessed. Furthermore, the study identified and ranked adaptation options for better agricultural water management to cope with climate change.
