Reimagining Coastal Resilience in a Multi-Hazard World

Submitted by rajeshkotappa on Wed, 05/27/2026 - 11:48

Coastal risk is no longer about a single hazard. It is about cascading failures across interconnected systems. Across the Indian Ocean and Asia-Pacific, earthquakes, tsunamis, cyclones, sea-level rise, and extreme rainfall are increasingly interacting to create compounding and systemic risks. These is a need to shift toward anticipatory risk governance, powered by: Earth Observation, AI/GeoAI, Digital twins and Impact-based early warning systems. Because resilience is not about stopping the waves. It is about preventing one crisis from triggering many others.

Geospatial analysis of land-use and land-cover changes in the Sikkim Himalaya, and insights for sustainable future

Our study analysed LULC changes between 1998 and 2018 in the East and South districts of Sikkim using multispectral Landsat imagery (Landsat 5 TM and Landsat 8 OLI/TIRS). We applied supervised classification with the Maximum Likelihood Classifier (MLC) and employed post-classification change detection techniques. The findings showed that built-up areas mainly expanded at the expense of agricultural land and vegetation, underscoring the unsustainable trajectory of the ongoing land use patterns.
