An increasing trend in the recurrence of natural disasters and associated impacts due to Floods, Glacier Lake out bursts, landslides
and forest fire is reported over Hindu Kush Himalyan (HKH) region. Climate change and anthropogenic coupled factors are
identified as primary factors for such increased vulnerability. The large degree of poverty, lack of infrastructure, poor accessibility
and uncertainties involved in understanding high altitude land surface and climate dynamics poses serious challenges in reducing
disaster vulnerability and mitigating disaster impacts. In this context effective development of Disaster Risk Reduction (DRR)
protocols and mechanisms have been realized as an urgent need. The paper presents the adoption and experiences of multi scale
DRR systems across different Himalayan member countries ranging from community based indigenous early warning to space based
emergency response and decision support systems.
The Establishment of a Regional Flood Information System (HKH-HYCOS) over Ganges-Brahmaputra-Meghna (GBM) and Indus
river basins promoted the timely exchange of flood data and information for the reduction of flood vulnerability within and among
the participating countries. Satellite based forest fire alert systems evoked significant response among diverse stakeholders to
optimize fire incidence and control. Satellite rainfall estimation products, satellite altimetry based flood early warning systems, flood
inundation modelling and products, model derived hydrology flow products from different global data-sharing networks constitutes
diverse information to support multi scale DRR systems. Community-based Flood Early Warning System (FEWS) enabled by
wireless technology established over the Singara and Jiadhal rivers in Assam also stands as one of the promising examples of
minimizing flood risk. Disaster database and information system and decision support tools in Nepal serves as potential tool to
support diverse stakeholders.
