Rethinking crop diversification under changing climate, hydrology and food habit in Bangladesh

Aminul Islam Akanda

Abstract


Extreme temperature, frequent and intensive flood, cyclone and other natural disasters due to climate change became acute in Bangladesh and would be severe in future.
Besides, water crisis due to shortage of upstream flow and very little rainfall in dry season would affect in a same way. Gradual higher dependency on groundwater irrigation during last few decades created pressure on groundwater even after a huge discharge during rainy season. Using secondary data, this research analyzed the changes in cropping pattern along with a forecast of area to be distributed among various crops in 2029-30 and proposed a re-distribution considering probable crop failure, water crisis and change in food habit.
Inherit rice-dominated food habit and government incentive policy encouraged farmers to be concentrated highly on water-intensive rice farming. However, a recent tendency of
less rice consumption would encourage crop diversification in future. An incentive policy for farming of diversified crops and their intensification in all crop seasons would be effective to reduce pressure on groundwater and to persuade a balanced food basket in Bangladesh.
