In Vietnam, early-season floods warn of climate change risks to come

The country finds itself increasingly on the disaster front line as storms become more erratic and intense

The floods came early this year in Tua Sin Chai, a remote village in Vietnam’s northern highlands. In June, heavy rainfall unleashed landslides that tumbled through this hillside village, killing a family of four

 

Giang Hong Ky lost his son, daughter-in-law, and two grandchildren when the tide of earth and rocks cascaded down the hillside. The 65-year-old has spent his entire lifetime here, but he said it’s the first time a landslide like this reached his village.

“My parents’ generation, my generation, and now my children’s have all been living in this village,” Ky said. “But we have never seen anything like that.”

Giang Hong Ky lost four family members when a landslide barrelled into his village in Lai Chau Province in June.

The damage was part of a series of landslides and flash floods in June and July that killed nearly 70 people and submerged thousands of homes in Vietnam’s northern provinces, including Lai Chau, where Ky’s family lives. Vietnam is already intensely exposed to disasters, but environment experts say climate change is making extreme weather increasingly frequent, unpredictable, and more severe.

Climate negotiators are meeting this week in Bangkok to continue hashing out guidelines that will determine how countries meet their commitments to tackle global warming.

Climate justice advocates say the results of the forthcoming discussions must help vulnerable countries adapt to and mitigate the impacts of climate change – like, they would argue, the early-season floods and landslides that hit Ky’s family and many of Vietnam’s northern provinces.

Experts say vulnerable families in remote communities are poorly prepared for the new climate reality: the escalating risks of damages and losses from increasingly unpredictable disasters, and preventable casualties in distant villages like Tua Sin Chai.

From his window, Giang Hong Ky can see the path of a landslide that killed his son’s family in June. It took a full day for villagers to find the bodies, which were buried under thick layers of rocks and soil.

More frequent, more intense

People in this region are used to the risks of floods and other dangers brought on by the monsoon season, which sends torrential rains over parts of mainland Southeast Asia – the heaviest downpours in Vietnam typically come in July and August. It’s also difficult to draw a definitive link between climate change and specific storms – or the resulting damage from floods and landslides. But climate scientists say all the signs of a changing climate are there: more frequent storms, erratic timing, and extreme impacts.

“Vietnam is experiencing more frequent intensity and unpredictability of weather patterns over the recent years,” said Dao Xuan Lai, head of the climate change and environmental unit at the UN Development Programme in Vietnam.

He points to Typhoon Damrey, which struck Vietnam last November – unusually late in the season. The storm killed more than 100 people and caused an estimated $422 million in losses and damages.

Already, Vietnam frequently ranks among the countries most exposed to extreme weather. Damrey was the sixth storm to make landfall in Vietnam last year alone – aid group Care called the storm season in Vietnam one of the world’s most under-reported humanitarian crises. The World Bank says nearly 60 percent of the country’s land area and more than 70 percent of its population are at risk of multiple hazards, including typhoons, floods, drought, and landslides.

Unprepared

Lai said many remote communities in Vietnam lack an effective disaster forecasting and warning system. When warnings are received, they’re often late or communities underestimate the risks. This means families often have little time to prepare.

Man-made factors have also exacerbated the risks.

Soil erosion from deforestation and agricultural practices like slash-and-burn cultivation – common in Vietnam’s northern provinces – can make landslides more likely, Lai said.

Slash-and-burn agriculture is common in Vietnam’s mountainous areas. This practice can cause soil erosion, making the land more unstable and exacerbating the risks of landslides during heavy rains.
Tan Thi So, 56, says illegal logging in his part of Ha Giang province was once rampant. His land was destroyed by floods and landslides in June: “You could hear the sound of landslides thundering in the air… I have never witnessed anything like that.”

Vietnam could take further steps to protect communities and help them cope with disasters and climate change, Lai said. This could include more sustainable land use, improved warning systems and communication of threats, better data collection, and insurance schemes to help people whose livelihoods are closely tied to the land and weather.

The Vietnamese government acknowledges that it needs to better prepare and plan for disasters, having called last year for a nationwide “disaster strategy”.

For now, remote communities hit by disaster this year are repairing the damage, but the heavy monsoon downpours continue.

The same floods and landslides that struck villages in Lai Chau province also hit communities in nearby Ha Giang province.

The damage is etched into the mountains: the paths of dozens of landslides are gouged into verdant hillsides like claw marks, scraping a trail through crushed wooden homes below.

The scars of the early-season landslides are still visible throughout Lung Tam Commune in northern Vietnam’s Ha Giang Province.

Vang Thi Hoa recalls being startled awake by a neighbour’s screams on a Sunday morning in June. Floodwaters had seeped into her home; all her family’s belongings were afloat. Frantically, she grabbed her children and dashed to safety. Within minutes, masses of earth and boulders swept down the slope and battered her house.

Hoa and her family survived. But the neighbour who roused her, Giang Thi My, died in the landslide.

Vang Thi Hoa’s house, furniture, and crops were washed away by a late-June landslide that killed her neighbour in a village in northern Vietnam’s Ha Giang Province. “I did not know what to do,” she says.
