Landslide Warning Systems in High-Income Countries: Past Accomplishments and Expected Endeavours

Abstract

AbstractSpecial emphasis has been given to the role Early Warning Systems (EWSs) can play as mechanisms for disaster risk reduction (DRR) around the globe. Along this line, the International Consortium on Landslides (ICL) has promoted several efforts to create regional and global network initiatives that include, among other relevant activities, landslides early warning systems (LEWSs). This task has actively involved the ICL community in supporting the implementation of the Sendai Framework for Disaster Risk Reduction (SFDRR) in all the nations included as members.Despite the advances in the development of LEWSs, their successful implementation worldwide remains a challenge to be addressed. Building on earlier efforts, an overview of the diverse dimensions of LEWSs in High-Income Countries (HICs) is provided in this chapter.Insights derived from a systematic literature review, are included in this document and organized into five sections. The introductory part focuses on the relevance of LEWSs in HICs and outlines the structure of the chapter. It is followed by a general reflection on hazard knowledge-based LEWSs. Details on the methodology used for this analysis are provided in the third section. The outcomes of the literature review are presented in the fourth section, while key messages are included at the end of the chapter.Technology development for potential LEWSs, hazard analysis for LEWSs, and models and prototypes for LEWSs are the main thematic focus of research in the analyzed publications.
