The recent Nepal flash flood, claiming 270 lives, highlights the Himalayan ecosystem's fragility, exacerbated by rising temperatures. Past disasters like Kedarnath and Sikkim underscore the region's vulnerability to floods, landslides, and glacial lake bursts. Attributed to glacier collapse and heavy monsoon, these events necessitate urgent action. The author stresses scaling up cooperation among Himalayan nations in data sharing, forecasting, and early-warning systems. Despite geopolitical differences, countries like India and China must prioritize securing lives by enhancing these critical hydromet frameworks, moving beyond rescue to proactive prevention as glacial melting intensifies, protecting communities.
