In early June, torrential rains swept via north-east India, killing no less than 46 individuals and displacing hundreds. In Assam, over 2.6 lakh individuals throughout 11 districts had been affected. Greater than 740 villages had been submerged, and 6,000 hectares of cropland went underwater. Landslides and floods collectively introduced the state’s demise toll to 27. As transport hyperlinks broke down in Manipur, Mizoram, and Tripura, rainfall information tumbled throughout the area.
India recorded 5.4 million inside displacements from climate-related disasters in 2024—the very best in South Asia—in accordance with the Inner Displacement Monitoring Centre’s (IDMC) International Report on Inner Displacement (GRID). Regardless of this, there stays no nationwide framework for figuring out or rehabilitating climate-displaced individuals. Catastrophe cycles have change into extra erratic and frequent, overwhelming conventional coping methods. Japanese States like Odisha and West Bengal, a lot of the north-east, and the hill areas of Himachal Pradesh and Uttarakhand are seeing sharper local weather shocks. Within the south, monsoon irregularities and flash floods are uprooting communities extra typically.
Whereas India has nationwide and State-level local weather motion plans, none tackle climate-induced migration. A 2020 research by Local weather Motion Community South Asia projected that 45 million individuals in India could possibly be forcibly displaced by 2050.
Based on GRID 2024, floods alone triggered two-thirds of India’s disaster-related displacements final 12 months—the very best degree since 2012. Cyclones brought about one other 1.6 million. Assam accounted for almost half of those actions, pushed by intensifying floods, deforestation, and decaying water infrastructure. Odisha and West Bengal managed large-scale preemptive evacuations due to early warning methods. Tripura, with out such methods in place, recorded its worst monsoon in 4 a long time, with greater than 3,00,000 individuals displaced.

A research by SEEDS (Sustainable Setting and Ecological Improvement Society) recognized 225 districts—largely alongside the coasts and the Himalayan belt—at excessive danger of future displacement. These zones, house to roughly 300 million individuals, face projected steep rises in climate-induced migration inside 5 years. “This implies round 300 million individuals could possibly be impacted by 2030 if we don’t act collectively,” mentioned Yezdani Rahman, Chief of Programmes at SEEDS.
In lots of of those districts, migration patterns linked to local weather pressures have already emerged. In Odisha and the Sundarbans, seasonal migration has change into routine. Males typically journey to main cities searching for work, leaving households behind. Migration right here isn’t short-term; over time, it hardens into permanence. The explanations are cumulative: collapsing agriculture, repeated house losses, and land rendered uninhabitable. “The Sundarbans, specifically, has a really excessive migration inhabitants, and that is ongoing,” Rahman famous.
Researchers say the absence of any official depend of climate-induced migrants makes it almost not possible to design focused insurance policies. In Odisha, cyclones, floods, drought, and lightning now overlap yearly. In West Bengal and the Sundarbans, rising seas and erratic rainfall patterns set off not simply riverine floods but additionally flash floods and dam overflows. As soon as seasonal, the climate has turned excessive and unpredictable.
Akshit Sangomla, correspondent and researcher with Down To Earth, says, “The dearth of information makes it very obscure the complete scale of what’s taking place. However we all know the jap states are the worst affected—yearly, disasters are hitting tougher and extra unpredictably.”
In Assam, now listed by the IDMC as India’s most climate-vulnerable State, migration has risen alongside the growing violence of the floods. The State’s residents—lots of them rice farmers—typically discover fields unusable after floods depart behind thick layers of sand. What was as soon as predictable is now unstable. Migration turns into the one choice.
Throughout Manipur, Nagaland, and Tripura, flash floods are adopted by extended dry spells. In Bihar, floods drive regular outward migration yearly. Jharkhand is going through related pressures. Within the Himalayan States of Himachal Pradesh and Uttarakhand, cloudbursts and landslides through the monsoon at the moment are routine, with whole villages left remoted or destroyed.
Down south
Within the south, Kerala has seen main flooding almost yearly since 2018. Sangomla notes that the majority migration within the State tends to be inside somewhat than outwards. Tamil Nadu and Maharashtra are seeing alternating cycles of long-term drought and sudden floods. These States are starting to point out indicators of accelerating climate-related migration. In Marathwada, tribal households typically enter cycles of debt-based migration, working underneath exploitative contracts after receiving loans they can’t repay. Each adults depart, whereas the youngsters keep behind. “This migration is much like bonded labour,” Rahman mentioned. “Contractors give them loans they will’t repay, and each husband and spouse work for months, leaving their youngsters behind. This can be a form of compelled migration.”

Alongside the jap coast, the influence is starkest. Total villages in Odisha have vanished underneath rising seas. In some areas, fisherfolk have deserted their properties completely. The Sundarbans face no less than one cyclone a 12 months. Rebuilding is commonly deserted after the third or fourth catastrophe. Individuals transfer. “The Sundarbans face no less than one cyclone yearly, typically extra,” mentioned Rahman. “We have now met households the place males haven’t returned for 3 years, attempting to economize for his or her little one’s marriage.”
Migration routes
Displaced communities typically relocate close by, solely to maneuver once more when work is unavailable. Some migrate to cities like Delhi, Mumbai, Bengaluru, or Hyderabad, sometimes with out their households. Others search work underneath MGNREGA (Mahatma Gandhi Nationwide Rural Employment Assure Act, 2005) or be part of casual labour circuits. Displacement typically turns into cyclical. Even after resettlement, many return to their ancestral land if livelihoods tied to the ocean or the soil are nonetheless viable. Within the Sundarbans, “Ladies typically work as home assist in tier-one and tier-two cities, whereas males often work as labourers or in handicrafts. Month-to-month incomes are sometimes beneath Rs. 3,000, far beneath the residing requirements,” Rahman famous.
In Odisha, relocation is typically initiated by the State, however not at all times coherently. In Satabhaya village, the place land loss resulting from rise in sea degree started within the Nineties, residents started protesting for relocation lengthy earlier than the federal government was ready to behave. Some left on their very own. Others waited. Finally, a relocation colony was created, however help was routed via a patchwork of welfare schemes somewhat than a devoted coverage. There was no regulation for local weather relocation, and little coordination. “However at the moment, the federal government didn’t have a coverage for such a state of affairs. It was a brand new form of problem, and State responses had been restricted by present authorized instruments,” mentioned Ranjan Panda, a local weather activist and sociologist popularly often called the “Water Man of Odisha”.
India has no formal class for local weather migrants. With out it, relocation stays improvised. Displaced individuals are hardly ever tracked, making long-term planning tough. Odisha has moved some coastal communities, however relocations are sometimes top-down. Communities are ceaselessly resettled with out session, resulting in dissatisfaction.
In lots of drought-hit areas, the place geography hasn’t vanished however has change into unlivable, no relocation course of exists in any respect. These locations have additionally reached their adaptation limits. “Initially, when farmland or properties start to be affected, individuals hope for State safety,” mentioned Panda. “But when issues don’t enhance, they lose motivation to remain. What is known as ‘voluntary relocation’ is, in truth, compelled—as a result of they’re left with no different choice.”
No nationwide resettlement coverage exists for climate-displaced individuals. In instances of infrastructure improvement—dams, highways—the displacing company is identifiable. However with local weather, displacement has no clear perpetrator. In consequence, there is no such thing as a designated framework for response. Help stays piecemeal: land or housing is typically supplied, however agricultural land, employment, and social assist are hardly ever included. “There is no such thing as a particular resettlement and rehabilitation coverage for climate-displaced individuals,” mentioned Panda. “In instances like dam or freeway initiatives, we all know who the displacing company is. However right here, there’s no single actor. That’s partly why governments haven’t developed a devoted local weather displacement framework.”
Localisation of local weather adaptation is essentially lacking. State and nationwide plans make point out of resilience however fail to deal with the lived expertise of these displaced. India is presently drafting its first Nationwide Adaptation Plan. It could be the nation’s first alternative to formally embrace climate-related migration in nationwide coverage. The earlier Nationwide Motion Plan made no point out of it. “State and Nationwide Motion Plans speak about local weather resilience, however not on the degree that may reply to the lived realities of weak communities. These paperwork are being revised now, however there’s little readability on how a lot native context is definitely being integrated,” Panda famous.
On the institutional degree, mandates stay divided. Local weather coverage sits with the Ministry of Setting, catastrophe reduction with the Ministry of Dwelling Affairs, and migration with the Labour Ministry. Researchers warn that this fragmentation stalls coordinated motion. A 2022 personal member’s Invoice—the Local weather Migrants (Safety and Rehabilitation) Invoice—proposed a nationwide framework, nodal authority, and devoted fund. It did not go however stays one of many few legislative acknowledgements of the difficulty.
Developments of attribution science
Attribution stays a problem. It’s tough to isolate local weather change as the only cause behind any particular migration. Displacement is commonly pushed by a mixture of components—financial hardship, caste, gender, or lack of land—of which local weather is just one. However as attribution science advances, extra occasions are being linked to rising international temperatures. This recognition, nevertheless, has not translated into coverage.
The time period “local weather refugee” has no authorized standing in India or globally. With out recognition, there is no such thing as a formal assist. Local weather finance—particularly from worldwide mechanisms—stays largely inaccessible for migration-related rehabilitation. Most responses fall again on catastrophe reduction or basic welfare entitlements, which seldom meet long-term wants.
Cyclone Fani, which hit Odisha in 2019, brought about 64 deaths regardless of evacuating greater than 10 lakh individuals. The cyclone spurred main catastrophe administration reforms, however local weather displacement nonetheless lacks a coherent coverage or institutional framework 20 years on.

Odisha’s expertise after the 1999 tremendous cyclone, when over 10,000 individuals died, marked a turning level. The State constructed a complicated catastrophe response system with early warning networks, coordinated evacuations, and civil society partnerships. The shift led to fewer deaths from subsequent cyclones, heatwaves, and floods. However the problem has advanced. Now, it isn’t nearly survival, however in regards to the continuity of livelihoods, group, and psychological well being. “Odisha centered on a zero-casualty strategy,” mentioned Panda, “and it labored—deaths from heatwaves, cyclones, and floods have diminished considerably.” But right this moment, with rising temperatures, altering rainfall patterns, and intensified disasters, “Zero deaths usually are not sufficient any extra,” Panda cautioned. “Lack of livelihoods and psychological well being impacts additionally have to be addressed. We have to transfer from emergency response to long-term local weather resilience.”
Researchers argue for a five-phased mannequin of resilience. It begins with anticipation: understanding native dangers. Then, survival: the flexibility to operate independently throughout a catastrophe. Subsequent, restoration: rebuilding with foresight. After that, adaptation: modifying methods to face new realities. Lastly, thriving: shifting past survival towards long-term well-being. “The phrase resilience is all over the place now,” mentioned Rahman. “However what can we imply by it, what are its parameters?” Restoration, he harassed, is especially difficult. “Research present that if a household experiences a significant catastrophe, it will probably take as much as 19 years to get better to their earlier standing—and restoration is gradual,” Rahman famous.
This mannequin requires group participation at each stage. With out it, even well-designed insurance policies falter. Catastrophe plans, if not demystified for peculiar residents, stay ineffective. Infrastructure should evolve—from cyclone shelters to raised college buildings and flood-resilient well being centres. In Assam, conventional stilt homes constructed by the Mising group are underneath pressure as flood ranges rise greater than their stilts. “Even District Magistrates could perceive 80 per cent of a catastrophe plan, however a typical individual could solely perceive 30 to 40 per cent. What use are plans if individuals can’t perceive them?” Rahman mentioned.

Based on Panda, Odisha, regardless of its popularity for preparedness, has important gaps. Local weather-resilient infrastructure stays sparse in lots of elements of India. “Resilience now must transcend catastrophe response. We have to put money into infrastructure that anticipates future threats,” Panda mentioned. He argued that States like Odisha want to have interaction proactively with international frameworks such because the loss and harm fund. “It’s not nearly receiving finance—it’s about making certain it reaches the bottom,” he mentioned.
Amendments to the Catastrophe Administration Act, handed in 2024, expanded the Nationwide Catastrophe Administration Authority’s (NDMA) function to incorporate local weather danger assessments. However the regulation nonetheless lacks mechanisms to account for State-specific vulnerabilities. Critics have identified that funding formulation stay tied to inhabitants and space, to not precise danger.
As sea ranges rise and rainfall patterns shift, India continues to lack a proper system to establish, assist, and combine climate-displaced individuals. These displaced proceed to maneuver—unseen, uncounted, and unsupported. “No group desires to go away its conventional space. Leaving means dropping their identification and rights over native sources,” Panda mentioned. “However when areas attain their adaptation limits—whether or not due to coastal erosion or persistent drought—migration turns into inevitable.”
