What ecological factors to integrate in landslide susceptibility mapping? An exploratory review of current trends in support of eco-DRR

Progress in Disaster Science, Год журнала: 2024, Номер 22, С. 100328 - 100328

Ecosystem-based Disaster Risk Reduction (Eco-DRR) reflects the important role that natural ecosystems play in reducing likelihood, severity, and impact of environmental disasters such as landslides. However, landslide risk assessments often lack explicit references to Eco-DRR unified frameworks, notably for its Landslide Susceptibility Assessment (LSA). Here, we assess how ecological factors are integrated into LSAs feasibility measuring them, using open Earth Observation (EO) data. We conduct an exploratory review identifying used ecosystem assessments, determining their commonalities. Key findings indicate standardization is more lacking than LSAs, with former exhibiting a higher dispersion factors—195 identified across 41 papers—compared latter, where only 46 were 30 studies. shared 19 common factors, two, Normalized Differential Vegetation Index (NDVI) Land Use Cover (LULC), being widely accepted criteria. Our study contributes advancing practices by proposing concrete measures expand perspective fostering collaboration between DRR conservation domains. Ultimately, it raises awareness pivotal healthy mitigating addressing societal challenges.

Engineering geological characteristics and failure mechanics of Jure rock avalanche, Nepal

Geoenvironmental Disasters, Год журнала: 2023, Номер 10(1)

Опубликована: Окт. 29, 2023

Abstract Introduction The rock avalanches are a frequent and disruptive phenomenon in the Himalayas other mountain chains. To minimize future losses, it is essential to investigate engineering geological causative factors mechanism of these mass wasting events. Study area present work aimed at assessing failure disastrous 2014 Jure avalanche along Araniko Highway, Northern Nepal. event had blocked Sunkoshi River an economically significant route China. Geotechnical properties analysis Initially, rockmass characterization intact strength attribute were determined for site classify zone. parameters measured obtained from field laboratory integrated into analytical models obtain conclusive interpretation mechanism. Structural, kinematic, key block theory analyses have been carried out decipher evolution Results discussion Rock was found be fair quality, however, structural instabilities presence water has led progressive failure. Movement subsequent sliding wedges foot appears possible Conclusion research explores contributory aspects avalanche. investigation results can used tackle similar large scale terrains thus minimizing losses.
