Kerala's multi-hazard risk ranking survived an uncertainty test
WHAT THE EVIDENCE SAYS
Researchers combined 30-metre terrain metrics, expert-weighted criteria and 10,000 Monte Carlo iterations to prioritize 31 sub-watersheds. Several high-risk units ranked consistently, with household-level damage data broadly supporting model priorities.
WHY IT MATTERS / OUR READ
Ranking stability should precede investment, but hazard susceptibility is not interchangeable with exposure, institutional capacity or mitigation performance.
CAVEATS / UNCERTAINTY
Expert-weight perturbations were limited to plus or minus ten percent; resulting map classes and validation apply to the study basin.
