Research Abstract |
Impact of climate change on soil erosion for all farmland in Japan was assessed. The values of rainfall erosivity, R for the past and the future were compared. The R values were estimated based on the daily rainfall estimation with RCM20, Regional Climate Model 20. The comparisons showed that average of the R values for the future were 1.23 to 1.26 times for the past. The result suggests that climate change would increase soil erosion in farmland in the future.
