keynote speech topicCatastrophic and continuous debris yielding from large gravitationally deformed slopes. Some deep-seated gravitational slope deformations transform into catastrophic failure, suddenly yielding a large volume of debris, and other deep-seated gravitational slope deformations continue to yield debris for a long time. Those examples would be shown in relation to sediment control.
Area of ExpertiseMy research addresses factors and conditions leading to the occurrence of different landslide types in high-mountain periglacial environments (Andes, Peru) or complex geological conditions (e.g., Central Europe, volcanic islands) aiming on assessing their hazard. It reflects the fact that landslides are social as much as natural phenomena and people have dealt with them for centuries developing various strategies and knowledge. Therefore, I am trying to understand how communities in different socioeconomical and political environments (e.g., Peru, Czech Republic) faced the landslide hazard and risk in the past to find the best ways how they can mitigate their risks in the future, which will be significantly shaped with effects of climate change.
Topic of keynote speechIn my talk entitled “Participative approach to landslide risk reduction for rural community in Peruvian mountains of Cordillera Negra”, I will share experience from more than 10 years-long effort to mitigate landslide risk in small rural community in Peruvian mountains of Cordillera Negra. The study site represents socially, culturally and geologically complex environment which limits applicable technical solutions for landslide hazard and risk reduction and demands high level of community participation in all landslide risk reduction steps. Successful and faulty strategies applied to perform this complex task will be described along with motivations and limitations of external expert involvement and its possible effects on long-term sustainability of the risk reduction measures.
