Disasters loom over South Asia with forecast of a hotter, wetter monsoon

KATHMANDU: Communities across Asia´s Himalayan Hindu Kush region face heightened disaster risks this monsoon season with temperatures and rainfall expected to exceed normal levels, experts warned on Thursday.

Temperatures are expected to be up to two degrees Celsius hotter than average across the region, with forecasts for above-average rains, according to a monsoon outlook released by Kathmandu-based International Centre for Integrated Mountain Development (ICIMOD) on Wednesday.

“Rising temperatures and more extreme rain raise the risk of water-induced disasters such as floods, landslides, and debris flows, and have longer-term impacts on glaciers, snow reserves, and permafrost,” Arun Bhakta Shrestha, a senior adviser at ICIMOD, said in a statement.

The summer monsoon, which brings South Asia 70-80 percent of its annual rainfall, is vital for agriculture and therefore for the livelihoods of millions of farmers and for food security in a region that is home to around two billion people.

However, it also brings destruction through landslides and floods every year. Melting glaciers add to the volume of water, while unregulated construction in flood-prone areas exacerbates the damage.
