ABSTRACT

There is a recognised need for bridging the gap between science and policy making aiming at the reduction of landslide disaster risk. A growing body of literature articulates the significance of scientific contributions on landslide risk assessment at different spatial–temporal scales. However, most studies in this field have mainly focused on landslide hazards, whereas vulnerability has not been treated in much detail. The present study aimed to portray the challenge involved within the integrated landslide disaster risk management sphere to avoid the configuration of new disaster risk. It should be understood whereby that landslide exposure is exacerbated by current population growth and the intensification of the use of land and resources linked to profitable activities, which in turn lead to rural transformation and a greater extent of socio-economic occupation of depreciated land in areas susceptible to hazards, urban sprawling and even expensive housing on unstable slopes. This analysis provides evidence about the need to encourage integrated landslide disaster risk management (ILDRiM), not only in the sense of reducing existing risk, but to prevent new landslide disaster risk. Thereupon, recognising and addressing landslide root causes and disaster risk drivers strongly intertwined to exposure and vulnerability should be prioritised, whereas the need of informed disaster risk governance must neither be neglected.

摘要

公认有必要弥合科学与政策制定之间的差距，以减少滑坡灾害风险。越来越多的文献阐明了在不同时空尺度上科学对滑坡风险评估的贡献的重要性。但是，该领域的大多数研究主要集中在滑坡灾害上，而对脆弱性的处理还不够详细。本研究旨在描述滑坡灾害风险综合管理领域所涉及的挑战，以避免新的灾害风险的形成。应该理解，当前的人口增长以及与有利可图的活动有关的土地和资源使用的加剧加剧了滑坡的暴露，这反过来导致了农村改造，并在易受灾，城市蔓延甚至不稳定斜坡上昂贵的住房的地区增加了对折旧土地的社会经济占用。该分析提供了有关需要鼓励进行综合滑坡灾害风险管理（ILDRiM）的证据，不仅从减少现有风险的意义上，而且还应防止新的滑坡灾害风险。因此，应该优先考虑认识和解决与暴露和脆弱性紧密相关的滑坡根源和灾害风险驱动因素，而决不能忽略对知情的灾害风险治理的需求。该分析提供了有关需要鼓励进行综合滑坡灾害风险管理（ILDRiM）的证据，不仅从减少现有风险的意义上，而且还应防止新的滑坡灾害风险。因此，应该优先考虑认识和解决与暴露和脆弱性紧密相关的滑坡根源和灾害风险驱动因素，而决不能忽略对知情的灾害风险治理的需求。该分析提供了有关需要鼓励进行综合滑坡灾害风险管理（ILDRiM）的证据，不仅从减少现有风险的意义上，而且还应防止新的滑坡灾害风险。因此，应该优先考虑认识和解决与暴露和脆弱性紧密相关的滑坡根源和灾害风险驱动因素，而决不能忽略对知情的灾害风险治理的需求。
