Change in area under different drought classes
due to climate change scenario in dry winter and
pre-monsoon (Area in sq. km)
Note Figures within parentheses indicate
increase () or decrease (-) in area over
existing. CCS-1 is 2C and CCS-2 is 4C rise in
temperature

ISSUES OF RWS Bangladesh
22
Percentage reduction in production of major crops
from the existing level under two climate change
scenarios over three levels of adaptation
practices
Note HA is High Adaptation Improved
technology and its wide adaptation MA is Moderate
Adaptation Farmers will be responsive and will
adjust with the change LA is Low Adaptation
Business as usual.
