| Research Abstract |
We have conducted research on devastated land in Northeast Asia based on field observations and remote sensing. Land has been changed in various ways including deforestation, litter sampling, plantation, and overgrazing, which caused decrease in infiltration capacity of soil due to reduced land surface coverage. This, in turn, caused severe soil erosion and is considered to be the direct cause of land devastation. In contrast, in China, an increase in infiltration capacity and a decrease in soil erosion by promoting afforestation have been reported. This research based on detailed field observations and remote sensing clarified that the infiltration capacity increased and the amount of soil erosion decreased with the recovery of the land surface coverage. Moreover, we were able to draw a MAP on changes in devastation in the East Asia by analyzing NDVI with remote sensing.
