BANGALORE & PAKHIRALAY, India, October 15 (IPS) - Bapi Mondal’s morning routine in Bangalore is a world away from his ancestral village, Pakhiralay, in the Sundarbans, West Bengal. He wakes before dawn, navigates heavy traffic, and spends eight long hours molding plastic battery casings. It’s not the life his honey-gathering forefathers knew, but factors like extreme storms, rising seas, and deadly soil salinity forced the 40-year-old to abandon centuries of family tradition and travel miles away to work in a concrete suburban factory.

Bapi still remembers his traditional skills—walking through a mangrove forest to find a tree with a honeycomb, mending boats and fishing nets, and singing and acting in the traditional plays. His 19-year-old son, Subhodeep—working alongside in the factory—has lost the heritage.

Bapi’s home, the Sundarbans—the world’s largest mangrove forest—is on the frontlines of climate change, and local livelihoods are taking the hit. In this watery maze where land and sea meet, villagers who once relied on fishing, honey collection and farming are now grappling with rising tides, saltier water, and more frequent storms. For many, life is becoming a struggle to hold on to centuries-old ways.

Sea levels in the Sundarbans are rising nearly twice the global rate, flooding villages and forcing families out. Saltwater ruins rice fields and ponds, making farming and fishing harder. Mawalis, the honey gatherers, also struggle as climate change disrupts flowering and damages mangroves, reducing wild bee populations.

The crisis doesn’t end with the water. Salinity, once held at bay by freshwater flows, is climbing year after year, disrupting both fishing and farming. Pollution, ill-managed embankments, and overexploitation of resources add to the challenge. As incomes shrink and lands disappear, thousands leave for nearby cities, hoping for work but often finding only life in urban slums.

City life is unforgiving for migrants like Mondal. He spends eight grueling hours on his feet, molding battery casings six days a week in harsh factory conditions. At the end of each day, he returns to a small one-room apartment. He shares this space with his wife Shanti and son, Subhodeep. The family struggles financially. Bapi earns ₹19,000 per month (about USD 215)—barely enough to get by. Despite the hardships, he says the work is still his choice.

“A hard choice, but a choice,” he explains.

Morning rush is hectic for the Mondal family. He points to the wall clock and asks his wife to pack lunch quickly. “All three of us work in different factories in the area,” Mondal says. “We all have to reach work by 8 am.”

Shanti, Bapi’s wife, spends her days at a garment factory pressing clothes with a hot iron. She works eight-hour shifts with just one weekly break, earning ₹15,000 per month (about USD 169). Their 19-year-old son, Subhodeep, has also joined his father at the plastic factory. All three now work in Bommasandra, Bangalore’s industrial belt, pooling their wages to survive.

The migration has split their family apart.

“We have an 11-year-old daughter who lives with my in-laws in the Sundarbans,” Shanti explains. The cost of city life forced them to leave their youngest child behind. “It breaks my heart to be apart from my daughter, but we want her to have a good education and life—that’s why we sacrifice,” says Shanti. Her daughter attends school back in the village.

Her job gave her economic independence and a voice in family decisions, like building their new house. Bapi’s family, rooted in the village for centuries, were Mawalis, honey gatherers who knew the forest through knowledge passed down generations.

Still Rooted

Bapi’s father, Gopal Mondal, still ventures into the dangerous forests of Sunderbans. He risks tiger attacks and deadly cyclones to collect wild honey. But the forest that once fed families is now failing them.

Climate change has disrupted everything. Cyclones strike more often and with greater force. The natural flowering cycle has gone haywire. Fish populations in the waters have crashed.

“The honey harvest keeps shrinking and prices keep falling,” Gopal explains.

As Gopal tried to hold on to tradition, his son Bapi could no longer see a future in the same waters and forests.

“The forest no longer provides enough honey or fish,” Bapi shares. The rhythms his ancestors lived by for centuries suddenly made no sense. Faced with shrinking opportunities, Bapi tried other work back home. Besides going to the jungle for honey with his father during the season (April-May), he operated a van gaari—a battery-powered three-wheeler with a wooden platform for passengers. But even that barely paid enough to survive. “There was a time when I struggled to buy a saree for my wife,” he recalls. Migration was the only choice left.

From Forests to Factories

Apart from forced migration, climate change erodes memory, identity, and ancestral knowledge. Leaving the Sundarbans has cost the family more than a homeland.

Bapi still carries traditional skills—navigating treacherous waters by boat and collecting honey deep in the forest.

“I know how to catch shrimp and crabs from the river and sea,” he says. “My father and uncles taught me these skills when I was young.”

His wife, Shanti, nods, adding that she was an expert crab and shrimp collector back in the Sundarbans. “I think I still have it in me,” she says with quiet pride.

But the chain of knowledge is breaking. “I could not pass on that wisdom to my son,” Bapi admits with regret.

Subhodeep represents this lost generation. He finished tenth grade and left his village to join his parents in Bangalore. He has not learned the skills that defined his family for generations. “I have never entered the forest to collect honey or fish back in the village,” Subhodeep explains. “My parents were against it.”

The irony is stark. Bapi’s parents encouraged him to learn these ancestral skills. But when environmental collapse made these traditions dangerous and unprofitable, Bapi chose to shield his son from them.

For the Mondals, the forest has become too dangerous and unreliable.

“Going to collect honey or catch fish is very unpredictable now,” Bapi explains. Catch volumes have fallen, and tiger attacks have grown. Bapi’s family knows the risk; his grandfather was killed while gathering honey in the forest.

Years earlier, a tiger also attacked Gopal Mondal. He was luckier—he escaped alive but still carries scars on his hand.

These brutal realities shaped Bapi’s decision about his son’s future. “I don’t want my next generation to have such a risky occupation,” he says. The choice is clear. Families can either cling to dangerous traditions that no longer pay enough to survive or abandon their ancestral practices for safer work in distant cities.

Are there other reasons behind the changes in the Sundarbans?

“We can’t just blame climate change and ignore human activities making things worse,” says Professor Tuhin Ghosh of Jadavpur University’s School of Oceanographic Studies. Human activity and climate change create a deadly combination.

People cleared mangroves for farms and fish ponds and built embankments that blocked tidal flows. The result is salt contamination, poisoned soil and water, vanishing species, and a broken landscape.

Uninhabitable Home

About 4.5 million people live across the Sundarbans region in Bangladesh and India. A recent survey reveals the massive scale of climate migration: nearly 59% of households have at least one family member who has moved away for work.

Some studies report 60,000 people migrated from parts of the Sundarbans by 2018. But household surveys show much higher rates because they measure affected families, not just individuals.

These local figures reflect a much bigger crisis. Across Bangladesh, weather-related disasters displaced 7.1 million people in 2022 alone, showing how climate change drives mass movement.

On the Indian side in West Bengal, researchers document large seasonal and permanent migration flows to cities and other states. Families routinely send members to work elsewhere, though official counts are scarce.

Loss Beyond Dollars

Over the past two decades, the Sundarbans has been hit by cyclones made stronger by climate change. They uprooted thousands and caused millions in losses. But beyond disaster relief and migration, a quieter crisis unfolds: the erosion of centuries-old ecological wisdom, culture, and tradition.

Gopal Mondal, in his early sixties, sits outside his modest home in Pakhiralay. When asked about protective equipment for his dangerous work collecting honey in the Sundarbans forest, he holds up a small amulet—a tabeej.

“This and my prayers to Bon Bibi are my protection,” says Mondal, who leads a team of honey collectors into the mangrove forests. “They shield us from storms and babu (tigers).”

The elderly collector recites mantras passed down through generations—teachings from his father or cousins, though he cannot recall exactly who taught him.

“The whole community worships Bon Bibi,” he explains simply

For Sundarbans communities like Mondal’s, Bon Bibi—the “Lady of the Forest”—is a guardian of the mangroves. For centuries, fishermen, honey collectors, and wood gatherers have sought her protection in tiger territory and cyclone-prone waters. Her worship is more than faith; it reflects the people’s bond with a dangerous yet life-sustaining environment, offering both comfort and identity where safety tools are scarce.

When asked about traditional knowledge slipping away from his family, Mondal’s weathered face shows a faint smile.

“Earlier, every fisherman’s family had someone —a son or grandson—who knew how to repair torn nets or mend boats,” he explains. “But in my family, things are slowly changing. My grandsons and sons live too far away, and their visits home are too short to learn these skills.”

The honey collector pauses, watching the distant mangroves. “The younger generation shows very little interest in our profession,” he adds quietly.

Climate migration expert M. Zakir Hossain Khan of Change Initiative, a Bangladesh-based think tank focused on solving critical global challenges, warns that climate-driven displacement from the Sundarbans is destroying centuries-old ways of life that depend entirely on deep knowledge of the forest and rivers.

Fishermen carry rare knowledge of tides, breeding cycles, and mangrove routes, passed down through years of practice. With youth leaving for city jobs, few inherit it. Honey gatherers know how to find hives, protect bees, and survive in tiger territory. As young people turn away, honey collection is fading from the Sundarbans.

A Vanishing Heritage

This generational shift reflects a broader transformation across the Sundarbans. Traditional skills that once defined coastal communities—net weaving, boat building, reading weather patterns, and forest navigation—are disappearing as young people migrate to cities primarily  for employment and a few for education.

“Similarly, mangrove-based handicrafts and boat-making using leaves, bamboo, and mangrove wood to make mats, roofing materials, and small boats demand both ecological understanding and artisanal skill, which are now rarely passed down,” comments Khan from Change Initiative.

He adds that herbal medicine and spiritual rituals practiced by local healers using plants like sundari bark and hental are also at risk, as migration and urbanization erode the cultural setting that sustains them.

Culture at Crossroads

Ghosh, who has spent over 30 years working in the Sundarbans, points to a troubling pattern.

“Migration is killing our folk arts,” he says. “Bonbibi stories, jatra pala theater, fishermen’s songs—they’re all disappearing. The people who used to perform during festivals are getting old. And there’s no one to replace them.”

The Sundarbans face a cultural crisis. Traditional performances that once brought villages together during religious festivals now struggle to find performers. Young people who might have learned these arts from their elders are instead leaving for cities for a better life

Once central to life in the Sundarbans, folk traditions like Jatra Pala, Bonbibi tales, and fishermen’s songs now fade with their aging performers. With few young apprentices, a rich cultural heritage risks disappearing—leaving behind a region not just economically changed, but culturally empty.
