Nepal Officials Admit Everest Flood Warning System Failed After £2.7 Million Investment

An early flood warning system in Nepal's Everest region, designed to safeguard thousands of lives, has fallen into disrepair, Nepalese officials have confirmed. This £2.7 million UN-backed initiative, implemented after the Imja glacial lake's 2016 drainage, has seen no maintenance, rendering its effectiveness questionable.

System Failure Leaves Communities Exposed

Villagers in the local Sherpa communities report no inspections of the project since 2016. Consequently, siren towers are rusting, with some even stripped of their batteries. Officials at Nepal's Department of Hydrology and Meteorology (DHM) acknowledge the satellite data reception, crucial for transmitting water levels and issuing mobile alerts, has proven unreliable.

While the Imja lake, situated at over 5,000m, has not burst since its depth was reduced by 3.5m a decade ago, scientists warn that accelerated glacial melting due to global warming is causing other Himalayan glacial lakes to expand dangerously. This poses a significant threat of sudden outbursts, capable of devastating downstream settlements and infrastructure. Ice loss rates in the Hindu Khush Himalaya region have doubled since 2000, according to the Kathmandu-based International Centre for Integrated Mountain Development, further exacerbating the risk.

Government Inaction and Displaced Funds

Ang Nuru Sherpa, chairman of the Chaurikharka buffer zone, expressed profound concern: "Going by the state of the siren towers, we don't expect to get any flood warning from them even when Imja lake bursts out." Jangbu Sherpa from Chhukung, a village directly in the lake's path, noted the absence of annual inspections promised by the DHM.

Niraj Pradhananga, a senior meteorologist at the DHM, attributed the failure to a lack of central government budget allocation. Archana Shrestha, the DHM's acting director general, conceded that funds were redirected to upgrade the warning system for another glacial lake, consuming all available resources. "That took all our resources and time, now we will move our attention to Imja lake," Shrestha stated, outlining plans for regulatory changes to facilitate future maintenance in the remote region.

The hydro-met station, responsible for real-time data transfer to Kathmandu, continues to experience issues. "We have not been receiving data as regularly as we need to and as a result we are unable to issue mobile phone alerts if there is flood," Pradhananga explained, highlighting ongoing disputes with the satellite company and its local service provider. Despite these failures, the UNDP has secured an additional £28 million grant to replicate the warning system in four other Nepalese locations, claiming "lessons from Imja" will ensure "long-term sustainability."

For communities like Phakding, downstream from Imja lake, the sentiment is one of abandonment. Nawang Thome Sherpa, head of a local body there, criticised the expenditure: "They spent millions of dollars in the name of protecting us from potential disaster - but we are having to live with fear of loss of lives and property every day."
