Climate change presents new threat to Philippines’ UNESCO rice terraces | Climate Crisis

Ifugao, Philippines – At first light, the village of Batad begins to stir to life beneath the towering cliffs surrounding its amphitheatre-like rice terraces, a UNESCO World Heritage Site.

Apu Penneng, an Ifugao elder who owns one of the village’s largest tracts of ricefields, struts with youthful confidence along a narrow and steep path in this highland community 1,100 metres (3,608ft) above sea level.

Dressed in a traditional loincloth, shawl and headgear, he is heading for the Tanig, an elaborate morning ritual before the harvest begins. At a courtyard next to rows of huts, dozens of village women also gather for the Bullogan chi Munbotoh, the procession to the harvest site.

Against the glow of the rising sun, the centuries-old terraces finally come in full view as if cascading from the sky. The fields of Tinawon rice grains, moist from the drizzle the night before, glimmer like morsels of gold ready for picking.

But the otherwise majestic landscape is punctuated by the sight of collapsed earth and boulders, right in the middle of the terraces.

In November last year, Super Typhoon Fung-wong triggered a landslide that killed two locals and demolished one of the centuries-old canals irrigating the rice paddies. About 2.2 hectares (5.4 acres) of rice fields were damaged, affecting 150 farmers.

“It was the worst we’ve seen here,” Apu Penneng calmly said, as he pointed to a deforested patch of land above the terraces. From afar, it looked like it had been slashed with a giant blade.

The wreckage has been an unwelcome reminder for villagers of the destructive nature of extreme weather conditions, which have been increasing in frequency in recent years.

Batad was also struck with landslides in 2011, 2023 and 2025. With the emerging threat of this year’s Super El Nino, a climate phenomenon that increases global temperatures and drives more extreme weather and rainfall patterns, the Ifugao people worry about more damage to come.

Across the world, 80 percent of UNESCO’s World Heritage Sites are facing climate-induced stress, according to an August 2025 study published in the scientific journal Nature.

The study found that UNESCO sites in low and middle-income countries receive the least conservation support, making them even more vulnerable to harsh climatic conditions. It added that in tropical monsoon areas, those conditions include record-breaking heatwaves, extended droughts and sudden drenching rainfall – much like what struck Batad in November 2025.

“Climate change is really aggravating the situation on the ground,” said lawyer Marlon Martin, head of the Save the Ifugao Terraces Movement (SITMO).

For the rice terraces to stay intact and stable, the soil needs to maintain a certain level of moisture year-round. But because of recent bouts of dry spells, deep cracks have developed, making the terraces prone to erosion, said Martin.

“When sudden bursts of rain occur, the water would seep into the cracks too abruptly, resulting in erosion” and even soil collapse, he added, warning that the Super El Nino could only mean more trouble ahead.

According to Steve Baccay, head of Ifugao’s Provincial Agriculture and Environment Office, an equivalent of $500,000 is needed for the restoration work in Batad following last November’s landslide.

Since the disaster, Batad residents themselves have come together a few times to do voluntary communal work called bachang to fix the demolished irrigation canal.

The social welfare and labour departments have also extended emergency food and cash assistance to affected farmers. However, additional national government aid is unlikely until the next fiscal year.

Climate change is nothing new, and for centuries people in Ifugao have adapted to the changes using Indigenous engineering techniques to protect the terraces, said Martin. But for Batad to withstand more frequent and more extreme weather, national intervention is needed, he added.

For Batad village chief Romeo Heppog and his family, the rice terraces are not just a source of their livelihood, but part of their identity and their way of life.

Organising the annual rice harvest festival is his way of honouring their ancestors and renewing their “sacred oath” to preserve the terraces for the generations to come, he said.

At the Tanig pre-harvest sacred ritual, Heppog watches closely alongside Apu Penneng as Apu Buy-a Nadyug, Batad’s chief Indigenous priest known as Mumbaki, leads the harvest rituals, including the pouring and drinking of fresh rice wine.

Hunched on the ground next to a pair of wooden Bulul, which embody invisible spiritual beings of the Ifugaos, the octogenarian Apu Buy-a Nadyug recites verses seeking blessings and protection for the harvest.

With the help of another village elder, Apu Penneng then leads the slaughter of chickens as a symbolic offering to Ifugao ancestors and the spiritual beings.

In one of the final acts of the hour-long sacred ritual, Mumbaki Apu Buy-a Nadyug then scrutinises the guts of the chicken, and pronounces another year of “bountiful harvest”.

Apu Penneng and Heppog then lead the banging of gongs signifying merriment and the start of the joyful harvest.

For a moment, the worries of the villagers of Batad are drowned out by the loud rhythmic sound that has been passed from generation to generation.

Apu Penneng then proceeds to his ricefield for the harvest.  Amid the uncertainties for his community, his face beams with pride as he gazes at the panoramic view of Batad.

From a distance, the 2,702 metres (8,865ft) Mount Amuyao, the country’s 10th highest peak, towers over Batad, as if guarding it from the threats of nature.

“We will get through this,” said Apu Penneng.
