A team from the Agricultural and Food Industry Technology Research Organization (Tsukuba City, Ibaraki Prefecture) reported on the 19th that if global warming becomes serious, the yield of rice nationwide will decrease by about 20% at the end of this century compared to the end of the 20th century. , Announced. It is estimated that the proportion of low-quality rice will also increase, accounting for about 40%. In addition to the high temperature, it was found that an increase in carbon dioxide (CO2) concentration has a combined effect.

The team pointed out that “the decrease in yield and quality will be more serious than previously predicted.” In addition to introducing heat-resistant varieties and taking measures to shift the timing of rice planting, he emphasized the need to reduce CO2 emissions.
