There is new evidence since AR5 that farming systems and crop areas will change in many parts of Asia in response to climate change. In South Asia, a study in Nepal showed that farmers are inclined to change practices in cropland use to reduce climate-change risk . In India, climate change is also predicted to lead to boundary changes in areas suitable for growing certain crops . A study in Bangladesh revealed a shift in crop choices among farmers, implying changes in the future rice- cropping pattern. Specifically, a temperature increase will compel farmers to choose irrigation-based Boro, Aus and other crops in favour of the rain-fed Aman rice crop .
