Abstract

Pluses and minuses of climate change on major cereal cultivation in Asia K. Okamoto*, M. Yokozawa* & H. Kawashima^ National Institute of Agro-Environmental Sciences, Japan. 2 Graduate School of Agricultural and Life Sciences, University of Tokyo, Japan. Abstract This paper describes the impacts of climate change on major cereal crops, i.e., rice, wheat and maize, in Asia using results from simulation studies using the CCSR (Center for Climate System Research, the University of Tokyo) GCM (Global Climate Model). Climate change could cause the air temperature and precipitation to become unsuitable for major cereal cultivation in Asia. To predict the impacts of climate change on sustainable cropping and agricultural development, we evaluated changes in climatic conditions in Asia in major cereal cropping seasons. We used the monthly average temperature and precipitation data from the 1961-90 mean climatology and CCSR GCM. We analyzed changes in the mean temperature and preci
