A landslide risk management framework considering the role of resilience

Abstract

<p>Landslides are causing a large number of fatalities and property damage around the world. In response to complex and unavoidable landslide disasters, actively enhancing the resilience of social systems is an essential disaster reduction strategy. Landslide risk management estimates the losses caused by landslides, evaluates the acceptability of those losses, and conducts risk control strategies to reduce those losses. Resilience, as an ability to cope with disasters, could significantly influence landslide risk. However, the traditional landslide risk management framework does not pay sufficient attention to the role of resilience. Hence, in this study, the role of resilience in a landslide risk management framework is systematically discussed after the relationship between resilience and vulnerability from a landslide risk perspective has been clarified. Then, we constructed a landslide risk management framework based on the role of resilience. In this framework, we have developed a landslide risk estimation method and a landslide risk evaluation method that take resilience into account. The consideration of resilience in risk estimation aids in the calculation of indirect losses and improves the results of direct loss analysis. Considering the resilience of social systems in risk evaluation can promote the establishment of a reasonable landslide risk tolerance threshold. As an indispensable role, resilience enables more rational landslide risk management for social sustainability.</p> <p>We published a portion of this research in the journal Geography and Sustainability (Citation: Tian, N.M., Lan, H.X., 2023. The indispensable role of resilience in rational landslide risk management for social sustainability. Geography and Sustainability. https://doi.org/10.1016/j.geosus.2022.11.007). In the above paper, we discussed the role of resilience in the key steps of a landslide risk management framework and constructed a landslide risk management framework considering resilience. On the basis of this, we do an extensive study and focus on developing methods for carrying out the suggested framework.</p>
