The Use of Geographical Information System (GIS) and Remote Sensing (RS) Technologies in Generation of Information Used to Mitigate Risks from Landslide Disasters: An Application Review

Abstract

Landslides, whether induced by nature, or human activities, are one of the most prominent disasters which are of great concern in the world. They cause a lot of havoc to the environment hence a necessity to avoid them whenever possible. This literature review is basically aimed at finding out how Geographical Information System (GIS) and Remote Sensing (RS) technologies are used in avoiding landslides and risks associated with them at different levels; Challenges encountered while using GIS and RS techniques for landslide disaster risk reduction are identified; and therefore, dealing with them requires the involvement of developed countries who have the capacity to provide the necessary equipment to the developing countries that are faced with disasters. This study discusses the use of GIS and RS in mitigation of risks from landslides, and mainly points out how these techniques are applied to avoid disaster risks. Secondary data was reviewed from journal articles, institutional reports, and online publications from similar studies. GIS and RS tools are important in predicting, monitoring and managing landslide disasters. It was concluded that GIS and RS tools provide cheaper, reliable, and faster techniques of accessing spatial data in a given area, therefore regarded as essential technologies that may be necessary for predicting landslide occurrences, these technologies need to be considered in communities which are prone to landslides.

Landslide risk management using geospatial technique: comparative insights of China and Indonesia

“…GIS technology in landslide risk assessment has proven effective in identifying high-risk areas and assisting in decision-making processes for mitigation and management (Nabukonde et al, 2023). Moving forward, it is crucial to enhance and refine GIS-based techniques for landslide risk assessment (Nseka et al, 2021).…”

“…This will enable a more comprehensive understanding of the dynamics and drivers of landslides in mountainous regions, ultimately enhancing the effectiveness of risk management strategies (Shah et al, 2020). However, a multidisciplinary approach is required to effectively mitigate landslide risks in these regions (Nabukonde et al, 2023). This approach should involve geoscientists, engineers, urban planners, and policymakers collaborating.…”
