In Eastern Asia, landslides caused by earthquakes had frequent and significant impacts on forest ecosystems and our lives. Furthermore, the number of rainfall-triggered landslides has been increasing due to extreme weather events. Thus, developing efficient procedures for risk reduction and ecosystem restoration after landslides is an urgent issue in our societies. Nevertheless, environmental restoration of landslide sites has been primarily addressed in the fields of sediment controls and environmental engineering with slope protection concretes, although ecologists have not paid much attention to landslides. The concept of Nature-based Solutions (NbS) has been rapidly spreading not only in science fields but also in policy and international arenas. Ecologists need to develop NbS for risk reduction and restoration of landslides. In this symposium, we will explore research projects on ecosystem restoration of landslide sites from an ecological, NbS viewpoint. First Prof. Lawrence Walker will provide a keynote lecture about the principle of plant succession. In the following three speakers will introduce the restoration projects conducted in large-scale landslide sites caused by the earthquake and artificial landslide experiment sites. Finally, one speaker will present the findings from forest restoration projects considering the natural processes. We would like to discuss future directions for risk reduction and restoration of landslides.
