The devastating landslides that worn out two villages present that local weather change is right here to remain and the necessity for adaptation is obvious and current.
“This was Mundakkai,” murmurs a rescue volunteer, pointing in the direction of his proper. From the place we stand, atop a destroyed home, the view is scary. An enormous expanse of land lies in entrance of a tall mountain, the earth uncooked and wounded, like an unlimited, lengthy scar. The soil is a muddy palette—ochre, russet, and umber mashed up by nature’s tough hand. The terrain is chaos itself—churned and pitted, studded with rocks torn from sleep. Ripped open, the land’s guts spilling over for all to see, and a newly enlarged river gleaming like contemporary gashes as a bunch of excavators claw deep, leaving grooves and furrows that snake throughout the location.
This is Mundakkai, a small, serene village in Kerala’s Wayanad district that, together with the close by villages of Punjirimattom, Chooralmala, and Attamala, was ravaged by three consecutive landslides within the wee hours of July 30, 2024. Heavy rains triggered the landslides whose supply was later found to be at Punjirimattam. Within the 48 hours main as much as the morning of July 30, the Mundakkai area noticed a staggering 572 mm of rainfall. Hillsides collapsed because of this, sending a torrent of mud, water, and boulders crashing down. The particles flowed into the affected areas beneath the mountains, which lay as a lot as 5-6 km away from the supply of the landslide. At the very least 250 individuals died within the pure calamity. Unofficial estimates put the loss of life toll at over 400 as there have been greater than 100 individuals but to be discovered and a number of other physique elements but to be recognized when this author visited the location.
Kerala woke as much as a panic-hit morning on July 30 as information channels began airing stunning tales of a whole bunch of individuals trapped within the mud and much more lacking or already presumed lifeless. Mundakkai was remoted for hours as the only real bridge that linked the village to close by Chooralmala and the remainder of the world was destroyed within the landslide that had set off a contemporary, livid river stream. The “new” river of particles wolfed up the whole lot that stood in its manner, together with the Vellarmala Authorities Vocational Increased Secondary College (GVHSS) in Chooralmala.

It was a frantic SOS name from Neethu Jojo, an govt on the Wayanad Institute of Medical Sciences (WIMS) in Meppadi, that first alerted the authorities of the huge landslide round 1:30 am. “Our homes are flooded. There was a landslide. We gained’t survive if one other one breaks. Please save us,” Neethu might be heard pleading with WIMS personnel in a broadly televised audio clip that went viral following the catastrophe.
Rescue employees recovered Neethu’s lifeless physique on August 3. By then the astonishing magnitude of the disaster, one in every of Kerala’s largest and most impactful pure calamities, had unravelled via media reviews, social media posts, and the pressing testimonies of survivors.

Vellarmala GVHSS alone misplaced 32 college students. The academics mentioned 22 our bodies had been recovered and 10 had been nonetheless lacking. “We’re but to come back to phrases with the shock. This was an exquisite college, and a peaceable village populated with such beautiful individuals and their kids. One evening of pure fury worn out all of the happiness we had amassed through the years,” Unnikrishnan, the college’s headmaster, advised Frontline. “I don’t understand how I’ll face my kids once they ask about their associates.”
The way it occurred and what might be finished to stop such calamities
- Within the 48 hours main as much as the morning of July 30, the Mundakkai area in Kerala’s Wayanad district noticed a staggering 572 mm of rainfall. Hillsides collapsed because of this, sending a torrent of mud, water, and boulders crashing down.
- At the very least 250 individuals died within the landslide. Unofficial estimates put the loss of life toll as scores remained lacking per week after the calamity. An estimated 5,000 persons are affected.
- The tragedy has triggered a debate round the way in which local weather change impacts have been ravaging Kerala specifically and the Western Ghats generally. A focus is the report of the Western Ghats Ecology Professional Panel, popularly often called the Gadgil committee report.
- However the authorities faces criticism for not doing sufficient on local weather mitigation and adaptation measures, particularly the way in which it handled the Gadgil report.
- The report proposed stricter regulation of growth actions in these zones, together with restrictions on constructing and infrastructure growth.
- One other committee, headed by Ok. Kasturirangan, was shaped to look at the report and recommend a manner ahead because the proposal to curb growth actions was discovered problematic.
- Local weather change is popping pricey for Kerala when it comes to human lives and financial loss. The 2018 floods alone price the State over Rs.40,000 crore.
- Quick-tracking local weather adaptation and mitigation efforts is, subsequently, essential, and early warning programs are considered essential to such efforts.
Complete households have been washed away, and there are a lot of households with just one individual left alive. Our bodies and physique elements had been being unearthed all through the week following the catastrophe, and the search and rescue operations continued because the journal went to press. Greater than 200 our bodies had been recovered from the Chaliyar river within the low-lying areas of Pothukallu within the close by Malappuram district, which lies on the opposite aspect of the mountains. The Chaliyar flows 30-40 km away from Mundakkai and Chooralmala.

An estimated 5,000 persons are affected. Even that could be a ballpark. Mundakkai alone is house to greater than 1,200 individuals, together with 200 kids, in additional than 400 homes. Chooralmala had over 2,100 individuals. The Kerala authorities has not finalised an estimate of loss to property and human lives but, however Income Minister Ok. Rajan says that the area is roughly estimated to have incurred a lack of Rs.1,200 crore. The State authorities has requested for an help of Rs.2,000 crore from the Centre.
Brilliantly coordinated and swift rescue effort
The Wayanad landslides witnessed some of the devoted, swift, and brilliantly coordinated rescue operations within the historical past of the State. The rescue efforts had been anchored on the strategic planning and execution capabilities of the Military, ably aided by the State forces and a Cupboard subcommittee that was constituted by Chief Minister Pinarayi Vijayan. The ministerial panel to supervise the rehabilitation and resettlement efforts consists of Income Minister Ok. Rajan, Public Works Minister P.A. Mohamed Riyas, Forests Minister A.Ok. Saseendran, and Welfare of Scheduled Castes, Scheduled Tribes and Backward Lessons Minister O.R. Kelu. S. Sambasiva Rao, a senior IAS officer, is supervising disaster administration operations together with District Collector Meghashree DR. A complete of about 700 Military males, State police personnel, hearth and rescue division personnel and forest officers, members of the Nationwide Catastrophe Response Power (NDRF), the State Catastrophe Response Power (SDRF), and native volunteers are engaged within the huge rescue effort.
The Military response was swift. On August 1, two days after the landslides, the Madras Engineering Group of the Military was capable of construct a 190-ft-long Bailey bridge, linking Mundakkai and Chooralmala to the remainder of the world. However even earlier than the Central forces got here onto the scene, the Kerala State Hearth and Rescue Providers personnel had been capable of create a short lived bridge with an extendable ladder which helped them rescue those that had been trapped throughout the bridge in Mundakkai, bringing down the general casualties considerably.
Chief Minister talks about local weather change, however Gadgil report was ignored
The tragedy has as soon as once more triggered an intense debate round the way in which local weather change impacts have been ravaging Kerala specifically and the Western Ghats generally. A focus is the Western Ghats Ecology Professional Panel; the WGEEP report is extra popularly often called the Gadgil Committee report.
Chief Minister Pinarayi Vijayan, in his night press meet following the tragedy, harassed Kerala’s vulnerability to modifications triggered by world warming and local weather change. He highlighted this once more when Prime Minister Narendra Modi visited Wayanad on August 10. Kerala’s Chief of Opposition V.D. Satheesan additionally mentioned the landslides in Wayanad and adjoining Kozhikode district confirmed that “local weather change can not be ignored”.
However the Kerala authorities faces criticism for not doing sufficient on local weather mitigation and adaptation measures, particularly the way in which it handled the Gadgil report that was submitted in 2011 by a panel headed by the famend ecologist Madhav Gadgil.

It had advisable that 64 per cent of the Western Ghats be declared an Ecologically Delicate Space with various levels of safety. Gadgil steered a ban on mining, quarrying, and sand mining in delicate areas. The report proposed stricter regulation of growth actions in these zones, together with restrictions on constructing and infrastructure growth. Many governments, together with Kerala’s, and native communities opposed the report, citing issues about its impression on growth and livelihoods. One other committee, headed by Ok. Kasturirangan, was shaped to look at the report and recommend a manner ahead.
After the July 30 landslide, Gadgil advised the media that the catastrophe may have been prevented if the suggestions of his report had been applied. He famous that growth actions and building of resorts had taken place within the delicate and very delicate areas of the Western Ghats, and these have been triggering landslides. “Such actions ought to be prohibited,” he famous, calling the tragedy “man-made”.

A number of research have confirmed Kerala’s susceptibility to local weather change. As not too long ago as August 14, a research by the World Climate Attribution, a reputed worldwide analysis group that tracks how local weather change triggers excessive climate occasions, linked human-induced local weather change to the Wayanad landslides. Researchers from India, Sweden, the US, and the UK collaborated on this evaluation, which discovered that excessive rainfall occasions triggering such landslides have turn out to be extra intense on account of world warming.
The research confirmed that heavy one-day rainfall occasions within the area have elevated in depth by about 17 per cent over the previous 45 years. “The Wayanad landslides are one other catastrophic instance of local weather change taking part in out in actual time,” says Mariam Zachariah, a researcher on the Grantham Institute—Local weather Change and the Surroundings, Imperial School London, and one of many authors of the research. Local weather fashions point out a ten per cent improve in rainfall depth attributable to human-caused local weather change, the research says.
“In at this time’s local weather, which is 1.3°C hotter than pre-industrial ranges, an occasion of this magnitude is anticipated about as soon as each 50 years,” the report states. The researchers warn that future warming can result in much more excessive rainfall occasions. The report additionally highlights how land-use modifications could have exacerbated the catastrophe. A 62 per cent discount in forest cowl and elevated quarrying have probably made the slopes extra vulnerable to landslides. The Ministry of Earth Sciences mentioned within the Lok Sabha that between 2014 and 2020, over 60 per cent of the three,656 landslides that occurred within the nation had been in Kerala.
A one-size-fits-all method could not work
However many worry {that a} one-size-fits-all method could not work in tackling local weather change and such excessive climatic occasions. “There’s a story being pushed that places the blame completely on human exercise, particularly issues like road-building, homes, and agricultural exercise, for disasters like landslides,” says T. Jayaraman, Senior Fellow, Local weather Change, M.S. Swaminathan Analysis Basis. “Whereas this could be true in some circumstances, it’s not at all times correct. The current landslide broke out in an space a ways away from human interference. The landslide’s location and the way in which it occurred spotlight the terrain’s susceptibility.”

Jayaraman says this factors to the necessity for a complete landslide monitoring and early warning system. Even a brief warning time might be essential. (Parliament mentioned the Wayanad landslide, with Residence Minister Amit Shah claiming early warnings had been issued. However a better examination of IMD information reveals that warnings weren’t particular or well timed sufficient to stop the tragedy.) Whereas some are dismissive of such programs, the rainfall ranges previous the landslide recommend that even a short warning may make a distinction, he notes, including that the main focus of our efforts ought to embody paying sufficient consideration to engineering options and early warning programs, empowering native communities to take motion. A 2019 report commissioned by the Kerala State Planning Board addressed flooding and landslides and will function a basis for additional motion, recollects Jayaraman.
“We want long-term options to such a disaster,” says Sekhar Lukose Kuriakose, who’s the Member Secretary (ex officio) of the Kerala State Catastrophe Administration Authority (KSDMA). “The baseline is land use,” explains Kuriakose. “In 1984, an identical landslide hit the identical space, and the particles circulate reached Chooralmala, however the human casualty was far much less, about 14 individuals, as a result of habitation was sparse and the land-use sample was completely different.”
Given Kerala’s high-density inhabitants, catastrophe preparedness, political response, and reception by individuals ought to all be in sync with the bottom realities, and these measures ought to be finished in a democratic manner, in coordination with all events involved, policymakers, scientists, civil society, and different stakeholders, notes Kuriakose. “It’s not a straightforward battle.”
Mundakkai and Chooralmala: Villages ravaged within the Wayanad landslides
Mundakkai and Chooralmala are lovely, small villages situated in Meppadi panchayat in North Kerala’s Wayanad district. Meppadi is understood for its hilly terrain and agricultural land, most of which belongs to Harrisons Malayalam Restricted (HML) tea plantations. Mundakkai borders Kozhikode and Malappuram districts. Past the tall mountains that border the world lie the famed Nilambur forests and the Chaliyar river.
The realm has a tropical local weather. These villages are primarily agricultural communities. Many residents work as farmers or plantation employees. Frequent crops embody espresso, tea, pepper, and varied spices. Some households additionally interact in small-scale livestock rearing. The villages have a mixture of conventional and trendy housing. Many properties are constructed on or close to hillsides. There are fundamental roads, small retailers, and some neighborhood buildings. Healthcare and schooling services are probably restricted.
The inhabitants is predominantly rural, with many residents having lived within the space for generations. The encompassing panorama options dense vegetation, streams, and steep slopes. This terrain makes the world vulnerable to landslides throughout heavy rains.
Local weather change is popping out pricey for Kerala when it comes to human lives and financial loss. The 2018 floods alone price the State over Rs.40,000 crore. Quick-tracking local weather adaptation and mitigation efforts is, subsequently, essential. Based on Kerala’s State Motion Plan on Local weather Change (2023-2030), the mixed price for each mitigation and adaptation efforts to fight local weather change in Kerala is roughly over Rs.90,000 crore.
Given the problem, prioritising engineering options, early warning programs, and adaptation methods is smart, say consultants. “Wayanad highlights the significance of adaptation and the error of conflating mitigation with adaptation. Each have their place, however we have to deal with the speedy challenges at hand, which for India is overwhelmingly that of adaptation,” says Jayaraman.
“Local weather adaptation methods should incorporate early warning programs to boost preparedness,” says Minu Treesa Abraham, a geotechnical analysis engineer with the Norwegian Geotechnical Institute, who hails from Kerala’s Kottayam district. “An efficient early warning system includes 4 key elements: setting, modelling, warning, and response,” she says. Setting includes figuring out organisational construction, stakeholders, obligations, and hazard varieties. It guides the selection of monitoring strategies, which can vary from native sensors to satellite tv for pc programs, relying on the kind of landslides, and the world and belongings to be protected. The warning stage establishes alert ranges and notification protocols. The response mechanism outlines evacuation procedures, relocation plans, media engagement, and public consciousness methods. Profitable implementation requires systematic coordination of all these parts, in line with Minu.
Minu says Kerala can be taught from the perfect practices adopted by landslide-prone international locations reminiscent of Switzerland, Italy, Japan, and Norway. These are among the geographies which have efficiently applied operational options in predicting landslides.
“When Pettimudi [Munnar] landslides occurred in 2020, we had been dealing with a scarcity of rainfall information. However the state of affairs is certainly enhancing, with robust efforts from KSDMA and different institutes. So issues are altering,” says Minu, pointing in the direction of the work personal analysis companies just like the HUME Centre for Ecology and Wildlife Biology and the District Catastrophe Administration Authority in Wayanad have finished.
‘Nobody was capable of predict the dimensions of the circulate’
Established in 2005 and situated in Kalpetta, HUME screens rainfall patterns in Wayanad and adjoining areas. This time as properly, they’d shared the info with the authorities. “Individuals who had been residing very near the mountains had been requested to depart the place or had been evacuated, however nobody was capable of predict the dimensions of the circulate. Nor had been we capable of forecast the drastic change within the river’s circulate path,” says C.Ok. Vishnudas, HUME’s director. Based on Vishnudas, the main focus ought to be on early warning. “The first triggering issue is local weather change-induced modifications in monsoon climate, which causes exceedingly heavy rainfall. Wayanad falls on this area, which sees what’s technically known as a mesoscale cloudburst.”
Hotter seas and cloudbursts
In recent times, meteorologists and local weather scientists have noticed an alarming improve within the frequency and depth of cloudbursts within the areas surrounding the Arabian Sea. These excessive climate occasions, characterised by sudden and intense rainfall, have been linked to the surplus heating of the Arabian Sea’s floor.
As world temperatures rise, the Arabian Sea absorbs extra warmth. This extra heating is especially pronounced within the months main as much as the monsoon season. The hotter sea floor enhances evaporation, resulting in a big improve in moisture content material within the decrease environment.
The nice and cozy, moisture-laden air rises quickly via the environment. Because it ascends, it cools and condenses, forming towering cumulonimbus clouds that may attain heights of as much as 15 km. In lots of circumstances, a number of cumulonimbus clouds organise into bigger, extra complicated buildings often called mesoscale convective programs. When these huge programs encounter topographic obstacles, such because the Western Ghats, they can lead to intense, localised rainfall, a phenomenon that known as a cloudburst.
Whereas cloudbursts should not a brand new phenomenon, their elevated frequency and depth have been linked to local weather change. As world temperatures proceed to rise, the Arabian Sea is more likely to expertise extra frequent durations of extra heating, probably resulting in extra frequent and extreme cloudburst occasions.
Understanding the connection between Arabian Sea heating and mesoscale cloudbursts is essential for enhancing climate prediction fashions and creating efficient catastrophe administration methods.
As we proceed to grapple with the results of local weather change, ongoing analysis on this space can be important for shielding weak communities and mitigating the impression of those excessive climate occasions.
Individuals in these areas keep within the valleys that lie between the mountains. The remainder of the world is used for plantations (the tea gardens of RPSG Group’s Harrison Malayalam Plantations occupy a significant chunk of Mundakkai and Chooralmala), and the unused swamps are used for constructing shelters for employees. So, finally, these swamps, which in a manner kind the drainage system of the mountains, turn out to be closely populated. However this additionally implies that the individuals right here should not protected, says Vishnudas. In 2020, the identical area noticed an intense landslide occasion, however individuals had been evacuated following alerts from HUME companies. “We have to count on such occasions through the monsoons now,” says Vishnudas.
His observations are corroborated by the truth that there was heavy rain within the Mundakkai-Chooralmala space and minor landslides had been reported within the final week of July. Individuals had been conscious that one thing was certain to occur. “However they weren’t clear or positive about how far the landslide particles would circulate down or how highly effective it could be,” says Ok.Ok. Sahad, former president of Meppadi Panchayat. The identical factor occurred within the Puthumala (August 8, 2019) landslide catastrophe. “However individuals had been evacuated earlier than the key occasion, thus saving treasured lives,” recollects Sahad. Just lately, there was a landslide with a 3-km runout within the close by Kurichiyarmala space, however the Forest Division was capable of evacuate individuals. However that didn’t occur in Mundakkai-Chooralmala due to many elements, together with the absence of a correct forecast on the potential distance the particles would journey.

Geotechnical engineers like Minu level out that India didn’t have an operational early warning system for landslides till very not too long ago. The Nationwide Landslide Forecasting Centre, arrange by the Geological Survey of India, was launched solely in July. The centre at the moment supplies day by day forecasts for Kalimpong, Darjeeling, and the Nilgiris. That is anticipated to be totally operational with protection to different areas in a decade, with warnings issued through the “Bhooskhalan” app in addition to the “Bhusanket” portal.
For native or site-specific warnings, sensor-based detection and early warning programs, just like the prototype developed by IIT Indore for Kalimpong or Amrita College’s wi-fi sensor community system in Munnar, work higher, regardless of their limitations. Specialists say prediction fashions are certainly enhancing, however every mannequin must be customised or tailor-made for the hydro-meteo-geological circumstances of the areas, and the kind of landslides. “As an example, within the case of particles flows, we have to have a mannequin that may calculate the runout distance [how far the debris flow can travel],” says Minu.
Additionally, the present susceptibility maps solely establish the supply areas of landslides. However the runout distance ought to be built-in into catastrophe administration plans to make them extra environment friendly. The sensible challenges of completely relocating everybody from such delicate areas ought to be thought of. If such programs come into place, casualties might be prevented utilizing momentary shelters in safer places.
In fact, there ought to be restrictions on future constructions and main infrastructure growth in such areas, and finally, long-term structural mitigation methods have to be deliberate, together with versatile obstacles, to scale back the impression of the circulate by the point it reaches human environments. The particles flows in Wayanad are often very deep because of the thick soil cowl, and it is very important perceive the phenomenon intimately in an effort to plan the measures to scale back the impression of circulate.
The Geohazards Analysis Lab at IIT Indore, led by Professor Neelima Satyam, has tried to mannequin the runout of some current occasions in Wayanad, and they’re nonetheless engaged on bodily mannequin assessments to know the rheological behaviour of particles flows. Extra such research are required on this route, because the elevated frequency of maximum rainfall occasions is more likely to set off extra particles flows in future.
No constantly obtainable shelters
Vishnudas factors to a different vital problem: shelters. “Persons are hesitant to maneuver out as a result of they don’t know the place to maneuver and the way. There are not any correct shelters or constantly obtainable shelters. Usually, they’re moved to makeshift locations or faculties, which they attempt to keep away from” he says. “This should change. We have to guarantee higher, bigger, and extra environment friendly shelter services and construct belief locally.”
In the long term, the state should make sure that individuals residing in such weak areas transfer out on their very own by sensitising them in regards to the risks and offering sufficient help for his or her resettlement, says Vishnudas.
“The federal government is focussed on tackling local weather change and strengthening alert mechanisms,” Income Minister Ok. Rajan advised Frontline as he ready for one more pressing assembly on the night of August 7 on the Wayanad Collectorate in Kalpetta. The downpour exterior mirrored the heavy weight of the catastrophe.

“Proper now, our speedy precedence is to make sure that rescue and rehabilitation efforts are executed flawlessly. We’ve recognized rental properties for the displaced and are envisioning a long-term plan that features a new township for the victims; it might be far-off from Mundakkai and Chooralmala.,” he mentioned.
Such a transfer could be a lifeline for lots of the survivors Frontline met on the Meppadi camp. “We will’t return. There’s nothing left for us there,” says Dinesh, a labourer, his voice hole as he stands exterior the reduction camp. He has misplaced practically 10 members of the family, together with his mother and father, brother, sister-in-law, and their kids, within the landslide.
Because the solar dips beneath the horizon, blanketing Meppadi, Chooralmala, and Mundakkai in a subdued yellow, an ambulance siren pierces the quiet. Faces, each of survivors and volunteers flip in the direction of the sound with a combination of dread and hope. The car could be carrying a well-recognized face, a misplaced beloved one.
