Resilience and sustainability in the management of landslides

Abstract

There are many regions worldwide which are susceptible to landslides, which cause loss of life and adverse impacts to infrastructure, environment and communities. Landslides are often triggered by exceptional rainfall and large-magnitude earthquakes. A range of strategies and methods have been developed to mitigate the occurrence of landslides and to reduce their impact, including risk to human safety. The adopted approaches and systems must be sustainable and resilient in relation to the communities that are at risk. This paper refers to an Australian regional case study of urban landslide management in the Wollongong region, New South Wales. The research carried out by the authors over two decades at the University of Wollongong has enhanced the resilience and sustainability of landslide management in the region. Reference is also made to Hong Kong as a case study of urban regional landslide practice, with particular reference to the upgrading of man-made slopes.

Earthquake‐Induced Chains of Geologic Hazards: Patterns, Mechanisms, and Impacts

“…Many landslide disasters since 1900 have had an earthquake origin (Chen et al, 2012;Froude & Petley, 2018;Gorum et al, 2011; section 2.1). Investigating the patterns of these processes is essential for risk mitigation, emergency response, reconstruction, and increasing resilience (Das et al, 2018;Flentje & Chowdhury, 2018;Petley, 2011). Integrating these processes over longer time scales reveals the way earthquakes shape mountain belts and provides diagnostics for identifying past earthquakes in sediment and landforms.…”

Identifying Landslides Prone-Areas Using GIS-based Fuzzy Analytical Hierarchy Process Model in Ziz Upper Watershed (Morocco)

“…Because of its wide spread as one of the most dangerous natural disasters, it has been studied by many researchers in different places: recently in Iran (Bahrami et al, 2020), in Kenya , in Serbia (Dokanovic, 2019), in India (Saha and Roy, 2019), in Malaysia (Lee and Pradham, 2007), in Turkey (Akgun and Bulut, 2007), in Italy (Pellicani et al, 2014), in Austria (Zieher et al, 2016) and in many other areas. These disasters have resulted in a large number of casualties across the world (Flentje and Chowdhury, 2016) and the loss of many properties, facilities, roads, forests and agricultural fields. Recently, an increase in the frequency of landslides has been observed and all the damage caused by them is often counted.…”

Comparative analysis of machine learning and multi-criteria decision making techniques for landslide susceptibility mapping of Muzaffarabad district

“…Considerable life and economic losses, and harmful influences on communities, environment, and infrastructure, relentlessly disturbing land use and urban development are caused by landslides, which are common natural hazards (Shahabi and Hashim, 2015;Flentje and Chowdhury, 2018;Zhu et al, 2018;Bragagnolo et al, 2020). Due to the increasing deforestation rates, unrestrained urbanization, and rising population density, the dangers of landslides have grown (Flentje and Chowdhury, 2018;Froude and Petley, 2018;Bragagnolo et al, 2020). To reduce and manage disasters related to landslides, it is vital to appraise zones susceptible to landslides (Hong et al, 2016a;Chen et al, 2018b).…”
