An agro-climatic study was conducted to assess the vulnerability of
winter rice (boro) production in Bangladesh to potential climate
change. Effect of climate change on yield of two varieties of boro
rice has been assessed using the DSSAT (v4) modeling system. The
yield of BR3 and BR14 boro varieties for the years 2008, 2030, 2050
and 2070 have been simulated for 12 locations of Bangladesh, which
were selected from among the major rice growing areas in different
regions of Bangladesh. Available data on soil and hydrologic
characteristics of these locations, and typical crop management
practice for boro rice were used in the simulations. The weather
data required for the model (daily maximum and minimum
temperatures, daily solar radiation and daily precipitation) were
generated for the selected years and for the selected locations
using the regional climate model PRECIS. The model predicted
significant reduction in yield of both varieties of boro rice due
to climate change; yield reductions of over 20% and 50% have been
predicted for both rice varieties for the years 2050 and 2070,
respectively.
