Ghoramara Island in the Ganga estuary of West Bengal is slowly being submerged by rising sea levels, forcing people to migrate in large numbers

For people living on the islands in the Ganga estuary, climate change is a demon they battle every day. It has already transformed their lives and livelihood. Nowhere is this clearer than in Sagar administrative block in West Bengal on the edge of the Bay of Bengal. This area is part of the Sundarbans, the world’s largest mangrove ecosystem and one of the areas most vulnerable to climate change in India.
The Sagar block, which has a population of around 200,000, has to not only grapple with a rising sea level at a rate that is nearly 250% higher than global rate (8 mm per year compared with 3.23 mm per year, according to the school of oceanographic studies of Jadavpur University in Kolkata), but also stands exposed to increasing high intensity cyclones and storms. The rising sea has already submerged Lohachara island in Sagar block, eaten nearly three-fourths of Ghoramara island and severely affected the bigger Sagar island.
The story of Ghoramara shows how climate change is changing the way people live – how it divides families, breaks social taboos and hastens forced migration. The largely poor people in the island (45% live below the poverty line) are under enormous socioeconomic stress that has upturned their lives.

Sagar Island (left) and Ghoramara Island (right) were attached in early 20th century. By the middle of the century older people say they could swim across from Ghoramara to Sagar during low tide in a few minutes. Today it takes about 40 minutes to reach Sagar Island from Ghoramara. The gap between the islands has increased mainly due to rapid erosion in Ghoramara.

Ghoramara Island, about 30 km north of the Bay of Bengal, has seen unprecedented erosion in last few decades. From 26 square km, it has shrunk to around 6.7 square km. The erosion has been rapid in past four decades with about 50% land sucked up by the Ganges during the period. The population, which once stated to be around 40,000, is now merely 5,193, according at the 2011 census. Lohachara, a neighbouring island, is totally gone. The Khasimara area of Ghoramara is fast disappearing.

An elderly couple, Kumed Mondal in his 80s and Madhuri Mondal in her mid-60s, live a lonely life in a mud house in Ghoramara. Their sons have long been left in search of greener and safer pastures and daughters are married. “The river was originally far off from our house but now it seems to be coming closer every day,” Kumed says. This seems to be the story of most families in Ghoramara. The elderly, and sometimes women, have stayed back to look after the vanishing property and hoping for some compensation from the government.

Nilmani Parua, in his 40s, lives alone in his two-roomed hut. Parua would have been a sought after groom anywhere in West Bengal but not in Ghoramara. Climate change has wrought a curious social upheaval. Anywhere else it’s easier to get the boys married, but in Ghoramara they struggle to get a wife unless she is from the same island. “Who will get his daughter married off in a family which lives in sinking island such as Ghoramara,” Parua says ruefully, sitting in his bachelor’s den.

The post office in Ghoramara was the second to be set up in West Bengal after Kolkata. Once a two-storied building on 36 acres of land, it is now reduced to a rented single room of 80 square feet. “Everything went under the water about 12 years ago and since then we have been working in this rented place,” says postman Abhimonyu Mondal. Now the post office closes around midday because there is very little work. “In average, 10 to 12 letters come every day. How much time do you need to dispatch them?” asked postmaster Srikanto Rana.

The human exodus outpaces the erosion in Ghoramara. While the island area has been reduced about one-fourth in its earlier size but the population has become nearly one-eighth. The mass migration has happened because of a loss in livelihoods. The lucrative betel leaf cultivation (pictured) has taken a severe beating due to continuous ingress of saline water. Increasing salinity in the water has also affected fishery, another major livelihood in the area. Many people have migrated to places like Kerala or Chennai in search of livelihood.

Mamata Bibi has been married into a family that had changed address five times, forced by the rising water. Now her family is searching for a new destination, preferably outside Ghoramara, as the present dwelling has come perilously close to the advancing river. “We do not know how long this house will survive. My brother-in-law, his wife and my husband have gone to scout for a piece of land outside Ghoramara,” says Bibi.

Dhoblat Sibpur in Sagar Island looks like nature is waging a battle against itself. The area opening up to the sea has few huts barely surviving alongside few trees. “This is our fourth house. Every time during the high tide, we fear being washed away,” says Liala Khatoon, tiptoeing carefully in ankle deep low tide water.

Sheik Istaq (left) and Sheik Mahmood, now in their sixties, left Ghoramara 45 years ago and now live in a resettlement colony within Sagar island, also called Ghoramara. Though life has become safer, it has become more difficult. “We had so much land in Ghoramara. When we were rehabilitated here 45 years ago along with 30 families uprooted from Ghoramara. Each family was given a small piece of land. It has now become extremely difficult to meet two ends,” Istaq says. “We still do not have electricity and other facilities which the sons of the soil from Sagar have,” says Mahmood.

Ghoramara has been sinking but there has been an effort to push back the inevitable as far as possible. Local lawmaker Bankim Hazra told indiaclimatedialogue.net that he has taken steps so that the island still receives development funding from the government. “It’s difficult, but we are trying to stop erosion as far as possible and save whatever is left in Ghoramara,” says Hazra. The poster says, “We want to save Ghoramara.”
