Climate Change Impacts on Rice and Wheat Production in Mymensingh and Dinajpur

Abstract

Climate factors such as temperature, rainfall, atmospheric carbon dioxide, solar radiation relative humidity are closely linked with agricultural production. Production of rice and wheat has become major concern in recent years for changing climatic conditions. A simulation study was conducted to assess the climate change impacts on rice and wheat production in Bangladesh using infocrop. The model simulated the yields of rice and wheat for the climate change scenarios of temperature, rainfall and CO₂ concentration. The effect of temperature on rice and wheat production is negative while that of CO₂ is positive, but temperature plays dominant role. The climate change impacts on rice and wheat production for both scenarios of historical and IPCC trends are negative, but the impacts are more prominent for wheat. Mymensingh is more vulnerable to climate change in comparison to Dinajpur.
