DHAKA, Bangladesh, September 17 (IPS) - Bangladesh is rightly praised for saving lives during cyclones and floods. Early warning systems, cyclone shelters and community mobilisation have turned once-catastrophic disasters into emergencies in which evacuation is often possible. But behind that success lies a quieter national failure: millions of people are being uprooted inside the country, often more than once, without a clear path back to secure homes, land or livelihoods.
Dr Mohammad ZamanAn internally displaced person, or IDP, is someone forced to leave home by conflict, violence, rights abuses or disasters, but who remains within their own country. That distinction is crucial. Refugees cross an international border and seek protection elsewhere. IDPs stay inside their state, where the national government remains primarily responsible for their protection and assistance.
In Bangladesh, this distinction is not academic. A Rohingya family that fled Myanmar into Cox’s Bazar is rightly understood as part of a refugee crisis. A Bangladeshi family forced from a riverbank in Kazipur-Sirajganj, a cyclone-hit village in Barguna or Patuakhali, or a landslide-prone hillside in Chattogram is internally displaced. The first case draws international refugee law and a global humanitarian apparatus. The second is too often dismissed as local misfortune, seasonal migration or urban poverty—even when the displacement is forced, repeated and long-term.
The drivers are unmistakable. Monsoon floods, cyclones, storm surges and landslides trigger large annual movements. Slower disasters—riverbank erosion, salinity intrusion and coastal land loss—make return impossible for many families. Conflict and violence produce smaller annual movements, but protracted displacement in the Chittagong Hill Tracts remains unresolved. Development projects, urban evictions and infrastructure expansion can also uproot communities when resettlement and compensation fall short.
The numbers show why Bangladesh can no longer treat internal displacement as a temporary humanitarian footnote. The Internal Displacement Monitoring Centre reported about 2.4 million disaster-related displacements in Bangladesh in 2024, up from about 1.8 million in 2023. Monsoon floods alone triggered around 1.3 million movements, including an estimated 723,000 in Sylhet division in June. Cyclone Remal added roughly 1.1 million displacements, many of them pre-emptive evacuations that saved lives but still disrupted homes, schools, work and local economies. Conflict and violence accounted for about 2,800 displacements.
New national evidence makes the picture starker. The International Organization for Migration’s Displacement Tracking Matrix estimated 5 million disaster-induced IDPs in Bangladesh in its 2025 nationwide assessment. Nearly two-thirds had been displaced before April 2020, meaning many have lived with displacement for years, not weeks. One quarter were concentrated in just four districts—Chattogram, Sirajganj, Bhola and Noakhali—while Chattogram and Dhaka divisions together hosted about 40 per cent of the estimated displaced population.
These figures expose an unequal geography of risk. Coastal households face cyclones, storm surges, saline water and embankment failures. Riverine communities in the north and centre lose land to erosion. City slums absorb families who arrive after disasters, only to place them in flood-prone, insecure and poorly serviced neighbourhoods. Women, children, older people and persons with disabilities face particular barriers in evacuation, shelter access, documentation, employment and safe housing. Displacement is not simply movement from one place to another; it can strip people of assets, identity, social networks, education and political voice.
Bangladesh’s IDP crisis is best understood as a development crisis with humanitarian symptoms. The country is comparatively strong at emergency response: it can warn people, open shelters and move communities away from immediate danger. The harder work begins after the water recedes—restoring land, rebuilding homes, returning children to school, replacing fishing gear or livestock, securing tenure in safer locations, and preventing displaced families from being pushed into exploitative labour or unsafe housing. Without durable solutions—safe return, local integration or planned relocation—each disaster deepens the last.
Bangladesh has a policy foundation, including its National Strategy on Internal Displacement Management. What it lacks is implementation at the scale demanded by climate reality. Internal displacement must be built into land-use planning, social protection, climate adaptation, urban housing, education, health care and local government finance. Data systems should distinguish short-term evacuations from protracted displacement. Relief, relocation and resettlement must be transparent, participatory and centred on livelihoods—not merely a transfer from one unsafe place to another.
Ashrayan, Bangladesh’s flagship housing program for landless and homeless families, offers both a useful model and a warning. Since 1997, it has given many poor households a legal roof, a small plot and access to basic services. For families living for years on embankments, khas land, riverbanks or in insecure urban settlements, secure shelter can be life-changing. But Ashrayan also shows why housing cannot be mistaken for rehabilitation. A house in the wrong place—without work nearby, transport, drainage, schools, health care or local accountability—can become another form of confinement. The real test is not how many units are handed over, but whether families can rebuild livelihoods and belong to the communities that receive them.
The recurring failures are practical and political. Too many Ashrayan-style resettlement sites are chosen because public or khas land is available, not because the location offers a realistic route out of poverty. Weak construction, poor drainage, inadequate sanitation, limited maintenance and exposure to floods or erosion can undermine relocation itself. Governance failures—unclear beneficiary selection, local influence, informal payments, land disputes and weak grievance systems—can be just as damaging. When these problems occur, families may gain a roof while losing the social networks, markets and informal economies that kept them afloat. Some commute long distances; some rent out or abandon the unit; some move again. That is not a failure of the displaced. It is a warning about policy design.
The future will be harsher if policy remains reactive. Climate change will intensify the hazards that already uproot families—heavier rainfall, stronger storm surges, sea-level rise, salinity and river erosion—while urbanisation will keep pulling displaced people into already strained cities such as Dhaka, Chattogram and secondary urban centres. Bangladesh has proved through cyclone preparedness that public policy can save lives. Its next test is whether those who survive disaster can also recover dignity, income and security afterward.
That begins with treating IDPs as rights-holders, not as casualties of bad weather. Bangladesh must move beyond emergency shelter toward secure housing, restored livelihoods and accountable national systems backed by climate finance. Resettlement must be written into land policy, local budgets, urban planning, social protection and climate adaptation before the next flood or cyclone arrives. The choice is stark: displacement can remain a conveyor belt into poverty, or it can become a national commitment to safety, citizenship and a future people can rebuild.
