The risk reduction effect of sediment production rate by understory coverage rate in granite area mountain forest

Abstract Ecosystem-based disaster risk reduction (Eco-DRR) is an important concept to the adaption of climate change for a sustainable life. In Japan, it is anticipated that damages caused by sediment production will be increased as the intensity and amount of rainfall are increased by climate chang...
