The contributions of BRRI to the second phase of the LACC project were concentrated in two districts Natore at the north-west and Khulna at the south west part of the country. In Natore, the climate is extreme in terms of temperature, rainfall; very high and low temperature along with low rainfall has threatened the crop production and livelihood of the farmers. While in Khulna district, salinity, natural disaster (sidr, ayla, nargis, resmi), rainfall and water stagnancy are the key environmental constraints where livelihood of hundreds of thousand of farm families are highly vulnerable.
