Nepal floods expose risks to hydropower in a warming Himalayas

DHADING, Nepal (AP) — Workers shoveled thick mud from a flood-ravaged power station in central Nepal, trying to revive a key node that supplies electricity to more than 20,000 people. But as they cleared debris from equipment buried by last week's catastrophic floods, there was hope the plant would not simply be rebuilt in the same place, beside the river that destroyed it.

In Nepal, up to 900 workers are unaccounted for from a dozen hydropower projects, according to the Independent Power Producers’ Association, Nepal, with hundreds believed trapped in tunnels. In Nepal and China combined, over 900 people have died and 4,700 are missing.

The loss of hydropower infrastructure is estimated to have taken 700 megawatts offline — about 10% of the country’s power capacity. Once the immediate aftermath of the disaster is dealt with, the question of how to restore power, roads, bridges, schools and health facilities quickly without rebuilding the same vulnerabilities should be on top of Nepalese authorities' minds. disaster experts said.

“Authorities have to take a hard look in the mirror now and ask how they will be rebuilding in these places. They will also have to take a close look at other projects in Nepal that have not been built yet, whether they’ll be approved after this event,” said Jakob Steiner, a geoscientist at the University of Graz in Austria, who is currently based in Dhaka, Bangladesh.

Hydropower projects that were operating or under construction were fully or partly destroyed across Rasuwa, Nuwakot and Dhading, among the worst-hit districts.

Many of the workers had taken shelter in the tunnels but are stuck, waiting to be rescued, according to officials.

“The tunnels are built to access hydropower infrastructure and to divert water,” Steiner said, describing the tunnels as big enough to drive trucks through.

Apart from the hydropower projects, tens of kilometers (miles) of roads, multiple bridges and essential buildings like schools and hospitals have been destroyed.

Ramraj Narasimhan, a senior director with the Coalition for Disaster Resilient Infrastructure, said rebuilding should focus on continuity of services rather than trying to make every structure indestructible.

“If it gets damaged, let it get damaged, but can we build in redundancy in the system?” he said.

That can mean choosing a better location for construction, alternate routes, backup power, improved early warning and financial tools such as insurance to speed recovery, Narasimhan said. Risk assessments should examine where a river bends, where slopes are unstable and where a single failure could cut off several communities.

Narasimhan’s organization estimates that $124 billion worth of Nepal’s infrastructure is exposed to climate-driven disasters, creating the potential for hundreds of millions of dollars in losses each year. A report by the coalition earlier this year found that Nepal’s average annual losses are nearly $760 million from various disasters, while the country’s national disaster funds is only a fraction of this amount.

Climate scientists said the Himalayan region — which is warming faster than many other parts of the world — is particularly at risk from increasing global warming as a result of human-caused climate change.

Climate experts said the flooding adds to evidence that infrastructure planning in the Himalayas is being forced to account for disasters that are increasing as the climate warms. Glaciers across the Hindu Kush Himalaya are losing ice at an accelerating rate, while permafrost degradation, unstable slopes, glacial lakes and increasingly erratic rainfall are raising the risks of floods, landslides and debris flows, according to reports by Kathmandu-based climate research group International Center for Integrated Mountain Development.

The stakes are particularly high for Nepal because hydropower is both a foundation of its electricity grid and an important source of economic growth and export revenue. Much of the country’s potential is run-of-river hydropower, Narasimhan said, meaning facilities are closely tied to steep river corridors where land is limited and hazards can cascade quickly.

Steiner said smaller floods can sometimes be managed with diversions that keep debris and high flows away from expensive infrastructure and tunnels. But for events as large as the latest flood, he said, physical defenses may be overwhelmed. In those cases, early warning becomes the critical protection for people.

He said the flood was detected at the China-Nepal border after moving rapidly from its source, leaving little warning time upstream. But there was still time as the flood traveled downstream toward hydropower sites, raising questions about whether warnings could have reached workers sooner.

The disaster is also likely to intensify scrutiny of where future projects are approved. Himanshu Thakkar, coordinator of the South Asia Network on Dams, Rivers and People, said environmental, social and disaster-risk assessments need to reflect the specific landscape and past hazards of each valley, backed by land-use rules and stronger accountability.

Hydropower projects can themselves become “force multipliers” when large structures, debris and altered river channels add to downstream damage, Thakkar said. He argued that Nepal should also consider more decentralized solar power as part of a broader energy mix.

Thakkar said the question now is not only how fast Nepal can rebuild, but what it chooses to put back in the path of the next flood.

An Iranian drone was intercepted early Monday over United Arab Emirates territorial waters, the Defense Ministry said. The attack followed an exchange of fire between Iran and the United States on the weekend, which was the first significant military action in the war for more than a month.

Here’s a look at the latest developments in the Iran war and the wider Middle East. Full coverage can be found here.

Iran fired a drone at the United Arab Emirates on Monday, which the UAE's Defense Ministry said was intercepted over its territorial waters.

After more than a month with no significant fighting, the U.S. attacked rocket launchers on an Iranian island on Sunday, saying they were preparing to launch mines into the Strait of Hormuz. Iran responded by launching missiles at U.S. sites in Jordan, all of which were intercepted.

Iran's President Masoud Pezeshkian said that his country was not seeking war, but that "we will respond decisively to aggressors. The UAE called the attack a “dangerous escalation” from Iran.

During the lull in fighting, the U.S. has been ratcheting up economic pressure on Iran with the hope of forcing concessions out of Tehran, including reopening the vital Strait of Hormuz to shipping.

An Israeli airstrike on Monday killed at least two Palestinians in Gaza City, hospital officials said.

The strike hit the entrance of a residential building near the city’s municipal park, according to Shifa Hospital, which received the casualties. Two other Palestinians were critically wounded, the hospital added.

There was no immediate comment from the Israeli military.

The deaths were the latest among Palestinians in Gaza since a ceasefire deal reached in October attempted to halt a more than two-year war between Israel and Hamas.

While the deaths since then have decreased, nevertheless at least 1,320 people have been killed by Israeli fire in Gaza, according to the Health Ministry.

Lebanon's Joseph Aoun is asking for Greece's help in implementing an agreement to end the war with Israel.

During meetings on Monday in Athens, Aoun told Greek President Constantine Tassoulas and Prime Minister Kyriakos Mitsotakis that Lebanon has been through long wars and “its people are tired.”

He suggested that Greece has good relations with both Lebanon and Israel and could help facilitate an end to decades of war.

In comments aired by local TV stations, Aoun referred to the U.S.-brokered framework agreement between Lebanon and Israel that was signed in late June, saying “we ask Greece to do all it can to help Lebanon in implementing the agreement.”

In an apparent reference to daily Israeli airstrikes and shelling despite a June 20, Israel-Hezbollah ceasefire, Aoun said that “trying to solve the problem through military force will not succeed.”

He said that the agreement “should not be implemented by one side but both sides.”

Mitsotakis told Aoun that “the security of Lebanon and Israel are not conflicting goals.”

“Greece, as a traditional friend of both Lebanon and the Arab world, but also a strategic partner of Israel, stands ready to support every effort toward de-escalation and mutual understanding,” he said.

The U.S. aircraft carrier USS Abraham Lincoln is nearing Thailand, where it is expected to make a port visit after its lengthy deployment to the Middle East.

The carrier with some 5,000 sailors and its accompanying battle group was sailing Monday toward the Gulf of Thailand where it was expected to make a port call near the city of Pattaya.

The Lincoln, one of the U.S. Navy’s largest warships, was supporting the U.S. war against Iran. Its deployment included a record-setting uninterrupted time at sea of more than 250 days.
