In northern Bangladesh’s flood-ravaged chars, families pool resources to raise shared earthen platforms six to seven feet high, creating islands of safety that shelter people, livestock and neighbours through months of inundation.

Every monsoon, the Teesta, Brahmaputra, Dharla and Dudhkumar rivers swell and swallow vast stretches of northern Bangladesh’s char lands. Homes vanish under muddy water, croplands turn into temporary lakes, and roads disappear. Thousands of families are left marooned for weeks, sometimes months. Yet amid the devastation, small clusters of raised earthen platforms rise like miniature islands, offering dry ground, shelter and a measure of dignity.

These are cluster homesteads – community-built elevated settlements that have quietly transformed survival strategies across Kurigram, Gaibandha and Lalmonirhat. Built six to seven feet above the surrounding land, they house three to seven families each and double as makeshift flood centres for neighbours whose own homes go under.

A Community Solution Born of Necessity

Most char dwellers cannot afford to raise land alone. Construction of a single cluster homestead costs between Tk 6 lakh and Tk 10 lakh. So three to seven families pool savings, labour and land – typically 10 to 20 decimals – to create a shared platform. Layers of soil are dumped and compacted, the top finished with clay for durability. Fruit, timber and medicinal trees are planted around the edges, helping stabilise the soil and providing long-term income.

Rakibul Hasan, executive engineer of the Bangladesh Water Development Board in Kurigram, notes that these platforms are deliberately sited at planned intervals to reduce the risk of riverbank erosion. “Climate change is making floods and riverbank erosion more frequent and intense,” he says. “Cluster homesteads are not just safe shelters during floods but a sustainable, disaster-resilient housing model for people living in Bangladesh’s vulnerable char areas.”

Some receive limited government or NGO support. Most are financed entirely by the families themselves. Landless and extremely poor households sometimes gain access to government khas land with priority assistance when they apply jointly.

Life on the Raised Ground

In Jorgachh village on the banks of the Brahmaputra in Kurigram’s Chilmari upazila, cluster homesteads were almost unknown seven or eight years ago. Today, around 150 of the village’s 200 families live on them.

Seventy-year-old farmer Nehat Ali remembers the turning point. “Four years ago, five families jointly built a cluster homestead on 18 decimals of land. We raised it about seven feet above the ground at a cost of nearly Tk 9 lakh. Now, even when floodwater surrounds us, our homes remain safe. Families whose houses go under water also bring their cattle and goats here for shelter.”

Mohor Ali, 65, from the same village, has not yet managed to join a cluster because of financial hardship. Every year he moves his family and livestock to a neighbour’s raised homestead. “It is impossible for a single family to bear the construction cost,” he says. He and three neighbouring families plan to build one together in the coming dry season.

Further west, in Haripur village on the Teesta in Gaibandha’s Sundarganj upazila, 70 families live across 18 cluster homesteads. The surrounding land typically stays inundated for four to five months. Farmer Jalal Uddin describes the surreal scene: “Water is everywhere, but our cluster homesteads remain dry and safe.” Transportation becomes the main challenge. Residents rely on banana-tree rafts, plastic-drum floats or boats to reach the mainland. Children, the elderly, women and men have all adapted to this watery commute.

In Dipchar Falimari on the Dharla shoal in Lalmonirhat Sadar, nearly 200 of around 300 families have moved onto cluster platforms. Sixty-year-old Amzad Hossain recalls how difficult life once was. “Now we can stay safely throughout the flood season. Landless families have also built cluster homesteads on government khas land with support from the government and NGOs. We have planted mango, jackfruit, banana and papaya trees around our homes and grow vegetables as well. Families living here share responsibilities and live together in harmony.”

Beyond Shelter: A Climate Adaptation Model

Experts increasingly view cluster homesteads as a practical climate adaptation strategy. Ahsanul Kabir Bulu, who works on livelihood programmes in Kurigram’s char areas for an NGO, says the elevated settlements help vulnerable families stay safer while reducing the impact of annual disasters. Lalmonirhat District Relief and Rehabilitation Officer Abdul Matin notes that the platforms function as community-level flood shelters. “If several families jointly apply to build a cluster homestead, they can receive government assistance. Landless and extremely poor households are given priority.”

Similar approaches have appeared elsewhere. Earlier projects under the Chars Livelihoods Programme raised individual and clustered plinths across multiple northern districts. NGOs such as Friendship have built larger oval-shaped plinth villages designed to minimise water impact, each able to house dozens of families permanently and hundreds more temporarily during emergencies. Inclusive models in Gaibandha have incorporated vegetable gardens, drainage systems and space for persons with disabilities.

These efforts sit against a backdrop of low overall flood resilience in char communities. A recent household survey in Kurigram’s Ulipur and Chilmari upazilas found an overall Flood Resilience Index of just 0.326, with particularly weak absorptive capacity. Households closer to the mainland fared better, underscoring the isolation and limited services that characterise deeper char areas.

Challenges That Remain

Despite their clear benefits, cluster homesteads are not a complete solution. Construction remains expensive relative to local incomes. Many families still cannot join. River erosion continues to threaten even carefully sited platforms. During prolonged inundation, access to markets, schools, healthcare and clean water becomes difficult. Women and children often bear the heaviest burden of restricted mobility and increased household stress.

Yet the model continues to spread because it is grounded in local knowledge and collective action. Families decide the height, the location and the shared rules of living. They plant trees that both protect the soil and generate income. They open their platforms to neighbours in crisis. In doing so, they convert a landscape of chronic vulnerability into one of mutual support.

As climate change intensifies the frequency and severity of floods across northern Bangladesh, the quiet success of these earthen islands offers a practical lesson: resilience grows strongest when communities raise the ground together.
