Spatial Distribution of the Effect of Temperature &Rainfall on the Production of Bororice in Bangladesh

Abstract

Climate is one of the major controlling factors for the well-being of the residents in the world. Global climate has been changing due to natural forces as well as anthropogenic activities, especially for emissions of greenhouse gases, aerosols and land use changes in recent decades. Climatic factors such as temperature, rainfall, relative humidity, cloud coverage, wind speed, bright sunshine etc. are closely linked with agricultural production. This paper mainly focuses on the effect of rainfall & temperature on the production of Boro rice. Rice production has been a major concern in recent years due to changing climatic conditions because significant amount of rice yield may be hampered for fluctuations in those climatic parameters. This study is limited to assess the effect of climate change on production of Boro rice in Bangladesh. Boro cultivation is held on dry season (mostly November-April in Bangladesh). Geographic Information System (GIS) is a tool to show the spatial distribution of the effect of these climatic parameters on the production of Boro in Bangladesh. This effect is shown by normalization of Boro yield by temperature and rainfall
