The complex and cascading extreme landscape events such as cloudbursts, floods and landslides are getting significantly pronounced in the Eastern Himalayan region spanning Nepal, India and Bhutan. The recent 2024/25 disasters, resulting in the loss of lives and livelihoods, have highlighted the urgent need for harmonised scientific evidence, transboundary collaboration. The project aims to address these critical gaps through a two-year, multi-dimensional research and capacity development initiative. The project will undertake a comprehensive systematic review of historical extreme events from the past three decades and undertake forensic analyses of selected events using synoptic, hydrological and socio-economic approaches. It will then develop landslide susceptibility maps and explore rainfall thresholds to support early warning applications. In between, the project will strengthen the capacity of at least 120 early-career researchers. Participatory field assessments, combined with community programmes, will strengthen awareness, local monitoring capability and risk communication. The project will further establish an open-access, cross-border hazard data repository, produce inclusive knowledge products (multi-language, Braille, and sign-language), and generate science-policy briefs and peer-reviewed publications thereby promoting cross-
country and long-term regional collaboration.
