Humid Heat in India is emerging as a growing public health threat. Through data, expert insights and lived experiences from across the country, EdPublica explores how rising heat and humidity are making everyday life increasingly difficult for millions of Indians.

By 9 a.m., Radha, a 55-year-old office worker from Kottayam in the southern Indian state of Kerala, is already drenched in sweat as she waits for her bus. By noon, waves of heat, anxiety and discomfort begin to set in. Menopause had already brought frequent hot flashes, she says, but rising temperatures and humidity have made them harder to endure.

For Radha, relief no longer comes easily. Even routine tasks feel more exhausting than they once did. Her experience reflects a growing reality across India and much of the world: climate change is not only making the planet hotter, it is making heat harder for the human body to bear.

Humid Heat in India Taking a Growing Toll

When high temperatures combine with high humidity, the body struggles to cool itself through sweating, its primary cooling mechanism. As moisture in the air increases, sweat evaporates less efficiently, causing heat to build up inside the body.

A recent analysis by Climate Central found that dangerous humid heat days have more than doubled globally since the 1970s. The average number of dangerous humid heat days has risen from around 10 days per year to 23 days annually.

Alarmingly, climate change is now responsible for nearly two-thirds of these dangerous humid heat days. The consequences are increasingly visible. A study examining mortality linked to extreme heat events since 2000 estimates that more than 260,000 people have died from heat-related hazards worldwide.

Globally, climate change is now responsible for six times as many dangerous humid heat days each year as it was in the 1970s, underscoring how rapidly the risk has intensified. In 2025 alone, the world experienced an average of 23 dangerous humid heat days. Climate Central estimates that 19 of those days, or 83 percent, were added by human-caused climate change.

“These findings show how profoundly climate change is reshaping our world,” said Kaitlyn Trudeau, Applied Climate Scientist at Climate Central. “Dangerous humid heat has gone from being an uncommon event to a defining feature of daily life in some regions, pushing conditions closer to the limits of what the human body can safely endure.” Climate Central’s analysis of 961 cities worldwide found that 69 percent, or 665 cities, are now experiencing significantly more dangerous humid heat days because of climate change. On average, these cities recorded 46 additional dangerous humid heat days each year during the last decade compared with a world without human-caused warming.

Researchers say the findings highlight how climate change is evolving from an environmental concern into a growing public health emergency, particularly in regions already struggling with heat exposure, limited access to cooling and inadequate health infrastructure.

What Is Humid Heat?

Scientists often use “wet-bulb temperature” to measure humid heat. The metric combines air temperature and humidity to estimate how effectively the human body can cool itself through sweating.

Climate Central defines wet-bulb temperatures of 25°C or higher as dangerous humid heat conditions. When humidity and temperature combine to push wet-bulb temperatures upward, the body’s natural cooling system becomes less effective.

In extreme conditions, the body can no longer regulate its temperature adequately, increasing the risk of heat exhaustion, heat stroke and even death.

Older adults, children, pregnant women and people with pre-existing health conditions face the greatest risks. High humidity can worsen cardiovascular stress, respiratory illnesses and other heat-related health complications.

“Dangerous humid heat has more than doubled since the 1970s. We’re already seeing the consequences play out in real time,” said Lisa Patel, Clinical Associate Professor of Pediatrics at Stanford Children’s Health and Executive Director of the Medical Society Consortium on Climate and Health.

“As a pediatrician, these numbers are a wake-up call. This kind of data is exactly the tool clinicians and public health officials need to anticipate where heat-related illness will strike and who is most at risk before people end up in the emergency room.”

How Humid Heat Is Affecting India

Humid Heat in India is already becoming visible in several cities, particularly along the country’s southern and eastern coasts.

According to Climate Central’s analysis, Tamil Nadu emerges as India’s most affected state. Tirunelveli experiences an average of 273 dangerous humid heat days annually, the highest among Indian cities. Chennai follows with 257 days, while Tiruchirappalli records 251. Vijayawada and Visakhapatnam in Andhra Pradesh, along with Kolkata and Mumbai, are also among India’s humid-heat hotspots.

The danger does not end when people move indoors.

A separate study by Climate Trends found that heat exposure frequently continues inside homes. Researchers monitored temperatures and humidity in 50 low- and middle-income households in Chennai between October 2025 and April 2026 and found that indoor temperatures regularly exceeded 32°C.

Some households experienced more than 5,700 hours above this threshold—equivalent to nearly eight months of continuous heat exposure. Most households recorded between 3,000 and 5,000 hours of such conditions.

The findings suggest that for many urban residents, especially those without access to air conditioning, relief from heat remains elusive even indoors.

Heat, Menopause and Everyday Life

For women such as Radha, humid heat can intensify already challenging health conditions.

The World Health Organization notes that hot flushes and night sweats are among the most common symptoms associated with menopause. These episodes involve sudden sensations of heat in the face, neck and chest, often accompanied by sweating, flushing, palpitations and discomfort.

Women who have undergone hysterectomy are known to experience more frequent and severe hot flushes. According to NFHS-5 data, nearly one in ten women aged 30 to 49 in some regions of India have undergone the procedure.

As temperatures and humidity rise, these symptoms can become even more difficult to manage, adding another layer to the health impacts of climate change that often goes overlooked.

A City Struggling to Cool Down

In Mumbai, 59-year-old driver Vikas says heat has become one of the city’s biggest challenges.

Water shortages are becoming more common, and even routine outdoor work is growing increasingly difficult.

“Sometimes people go to the beach at night just to find some relief from the heat. Even a brief spell of rain feels like a blessing now,” he says. “The problem is only going to get worse.”

His observations echo broader climate trends in the Mumbai Metropolitan Region. Climate Central’s analysis shows that Mumbai experiences an average of 206 dangerous humid heat days annually, while nearby Dombivli and Thane record even higher numbers. The conditions he describes are reflected in current forecasts. Climate Central projected a daily high wet-bulb temperature of 25.6°C in Mumbai on June 23, a level considered dangerous humid heat.

Surfing Through a Hotter Coastline

Further south, the effects are also being felt along India’s coast.

Rajaguru, a surfing instructor in Puducherry, says summers are arriving earlier than before, often beginning in February instead of March.

“We go surfing early in the morning, but even then the heat feels much more intense than it used to,” he says. “Sunburns and skin rashes are becoming common. Summer arrives with extreme heat, while the monsoon season increasingly brings cyclones.”

He has also noticed rising sea temperatures and changes in water conditions that affect both tourism and outdoor activities.

For people whose livelihoods depend on spending long hours outdoors, humid heat is becoming more than an inconvenience—it is becoming an occupational hazard.

The Vulnerability Gap

These experiences reflect a larger challenge facing India. The impacts of Humid Heat in India are magnified by inequalities in access to cooling, housing and reliable electricity.

Between 1995 and 2024, the country experienced 430 extreme weather events, resulting in more than 80,000 deaths and economic losses exceeding USD 170 billion. Rapid urbanisation has intensified the urban heat island effect, making cities significantly hotter than surrounding rural areas.

The latest Climate Change in the Indian Mind survey found that 84 percent of Indians report experiencing the effects of global warming. Yet only 15 percent of households own an air conditioner and 27 percent have access to an air cooler.

Even for those with cooling systems, reliable electricity is not guaranteed. Around 66 percent of Indians experience power disruptions on a typical day, even as demand surges during heatwaves. On May 21, 2026, India’s peak electricity consumption reached a record 270 gigawatts.

Despite being the world’s third-largest emitter of carbon dioxide, India’s per-capita emissions remain relatively low, reflecting deep inequalities in energy consumption and access.

For millions of people, escaping extreme heat is simply not an option.

When the Air Stops Offering Relief

Dangerous Humid Heat in India is already reshaping how people live, work and survive. As temperatures and humidity continue to rise, the boundary between uncomfortable and life-threatening conditions is becoming increasingly thin.

For millions of Indians, the challenge is no longer adapting to hotter days. It is adapting to air that no longer offers relief. As humidity rises alongside temperatures, surviving heat may become as much about access to cooling and electricity as it is about climate itself.

The future of climate adaptation may begin not in policy documents or air-conditioned offices, but in homes, buses, streets and workplaces where the heat is already impossible to ignore.

When the Monsoon Returns, Fear Returns: How Climate Disasters Are Reshaping Mental Health in Himachal Pradesh

In Himachal Pradesh, repeated floods and landslides are reshaping mental health in the mountains — but disaster policy still doesn’t see it.

“As soon as the monsoon arrives, fear spreads across the village. People panic because they have already seen what these rains can do. In 2023 and again in 2025, many families here lost their homes, farmland and orchards to monsoon disasters. The moment it starts raining heavily, everyone fears history will repeat itself.”

Het Ram, a resident of Siraj Valley in Himachal Pradesh’s Mandi district, pauses before adding a detail that has quietly become part of everyday life. Most households in his village now keep their important documents, first-aid kits, clothes, dry food, drinking water, ropes and tarpaulin packed together in one corner of the house, ready to be carried at a moment’s notice if disaster strikes.

“Without our documents, we cannot even claim government compensation,” he says.

Why Himachal Pradesh Floods Continue to Haunt Survivors

Het Ram’s experience is shared by families across many villages in Himachal Pradesh, where the monsoon — once welcomed as a season of abundance — has increasingly become synonymous with fear. With the first spell of July rain comes an unspoken anxiety that settles over entire communities. People’s eyes remain fixed not on the clouds but on the fragile mountain slopes towering above their homes. A spell of intense rainfall is enough to keep families awake through the night. Fluctuating blood pressure, panic attacks, insomnia and chronic stress have gradually become a routine part of life in the state’s vulnerable mountain settlements.

Psychologists describe this condition as anticipatory anxiety — the distress that emerges not after a traumatic event but from the constant fear that it may happen again. A study of disaster survivors in Uttarakhand found that repeated exposure to natural disasters leaves people in a permanent state of hypervigilance: interrupted sleep, startling at the slightest sound, and feeling anxious the moment it begins to rain had become routine for many of those affected.

‘I fear the mountain above my home may collapse’

For 56-year-old Chudamani of Sarpada village in Rampur subdivision, July is no longer just another month — it is a season of dread.

Whenever it rains, sleep deserts her. She spends hours sitting outside her house, her eyes fixed on the hillside looming overhead. A single fear keeps returning: What if the mountain gives way? What if everything is gone within seconds?

The fear has haunted her ever since the devastating flash floods of July 2024, when a swollen Samej Khad swept away both her two-storey house and her vehicle.

“Nowhere feels safe anymore,” says her husband, Chatar Singh. “The moment the rains begin, fear settles into our minds. Every spell of heavy rain makes us wonder which family’s home will be destroyed next.”

The scale of destruction behind the anxiety

According to the Himachal Pradesh State Disaster Management Authority, 2,108 people lost their lives during the monsoon seasons between 2020 and 2025, while property worth thousands of crores of rupees was destroyed.

The 2023 monsoon alone claimed 404 lives, left 38 people missing and forced more than 50,000 people to abandon their homes. A total of 2,546 houses were completely destroyed and another 10,853 suffered partial damage. Overall losses crossed INR 12,000 crore.

On August 14, 2023, a landslide in Shimla city killed 20 people. The following year, a cloudburst in the Samej area of Shimla district triggered flash floods that washed away 32 houses and claimed 36 lives. These recurring disasters across Shimla, Mandi and Kullu districts have left behind more than physical and economic devastation — every monsoon now revives memories of loss, uncertainty and the fear of losing loved ones all over again.

‘Not even a needle found after floods’

Alok Kumar of Sarpada village in Rampur embodies the depth of this trauma.

His ancestral home in Samej village was completely washed away in the 2024 floods. His mother and eight tenants lost their lives in the disaster.

“The flood was so devastating that not even a needle remained from our 21-room house,” he recalls. “I still haven’t recovered from that tragedy. Every time I hear about floods or landslides, the entire scene flashes before my eyes. We live in the mountains, so there is always the fear that another disaster could strike at any time.”

He says disasters have become an annual reality.

“For the last three years, something has happened every monsoon. It has increased stress and anxiety among almost everyone in the village. Even the elderly say they have never witnessed anything like this before.”

Despite struggling emotionally, Alok has never sought professional help. Like many others in disaster-prone regions, he considers such distress an unavoidable part of life in the hills.

What doctors are seeing

Mental health professionals in Himachal Pradesh say the psychological toll of climate disasters is becoming more visible, even though systematic evidence from the state is still lacking.

Dr Dinesh Dutt, a psychiatrist at Indira Gandhi Medical College (IGMC), Shimla, says climate change is directly influencing people’s mental well-being.

“Climate has a direct impact on mental health. After monsoon disasters, many survivors continue to relive the traumatic event. Distressing thoughts, memories and images keep recurring in their minds. Clinically, we recognise these symptoms as anxiety and post-traumatic stress disorder (PTSD). We are seeing such cases in hospitals, and our assessments suggest that climate-related events are contributing to these psychological conditions. However, there is still no systematic research that conclusively establishes this link in Himachal Pradesh.”

He adds that the state currently lacks a comprehensive database documenting climate-related mental health cases.

The concerns raised by clinicians are echoed in scientific literature. A review published in Frontiers in Public Health (2025) found that sudden climate-related disasters such as floods, landslides and cyclones frequently lead to PTSD and acute anxiety, while repeated exposure to such events has been associated with depression, hopelessness and, in some cases, suicidal thoughts. Mental health experts believe a similar pattern is gradually emerging in the rural regions of Himachal Pradesh.

Children are carrying the burden too

The psychological impact of recurring disasters is becoming increasingly visible among children.

Mukta, a government schoolteacher in Rohru, says classroom behaviour has changed noticeably since the devastating monsoon of 2023.

“Children have become frightened of the rains. During heavy rainfall, some of them become unusually quiet. Since Rohru is an apple-growing region, many children also worry that their family’s orchards and livelihoods may be destroyed.”

Poonam’s ten-year-old daughter, who lives in Shimla, has also developed an intense fear of the monsoon. Their residential building was declared unsafe after a landslide last year, forcing the family to live with relatives for ten days.

“Since that incident, she has developed a deep sense of insecurity,” Poonam says. “Every time it starts raining, that fear returns.”

For teenagers, the consequences are often less visible but equally profound.

Ashish Dogra, a Class XII student from Ramnagar in Shimla, says the rainy season has transformed childhood routines.

“During the monsoon, no one goes out to play anymore. We stay indoors all day. We talk to friends on the phone, but after a while it becomes boring. Sometimes that isolation makes us irritable and angry.”

Psychologist Neelam Bali says children’s emotional responses are closely linked to the anxiety they observe within their own families.

“When children see their parents constantly worried, they internalise that stress. Most are unable to express their emotions openly, and over time the anxiety begins to show in their behaviour. It eventually affects their studies and overall school performance.”

She emphasises that parents need to encourage open conversations with children.

“Play is one of the most effective ways for children to cope with stress. If they remain cut off from outdoor activities for long periods, they are more likely to experience loneliness, irritability and anger.”

Dr Dutt adds that climate disasters affect children, adults and older people in different ways. “If survivors do not receive timely psychological first aid, the long-term health consequences can be significant.”

When landscapes become a source of grief

Natural disasters alter far more than homes, roads and livelihoods. They also transform people’s emotional relationship with the landscapes they have known all their lives.

When the mountains that once symbolised safety and belonging suddenly become a source of destruction, recovering emotionally is rarely easy.

Researchers describe this experience as solastalgia — the distress people feel when the environment they identify as home is damaged or transformed. Unlike nostalgia, which is a longing for a place left behind, solastalgia emerges while people remain in the very place they call home, watching it deteriorate around them. Over time, this distress can deepen into prolonged grief, anxiety and depression.

Shifting homes in search of safety

Discussions around migration from Himachal Pradesh’s hill districts have traditionally centred on employment, education and infrastructure. But a new driver is quietly emerging: the search for psychological security.

For some families, the fear of living in disaster-prone areas has become so overwhelming that they are abandoning ancestral homes for places they perceive to be safer.

Prabhat Chand, 47, a government school lecturer from Rampur, is one such resident. After the devastating floods in Samej, he decided to leave the area and build a new home nearly 17 kilometres away in Sarpada village.

“Most of the families affected by the disaster have moved elsewhere,” he says. “The flood was so destructive that the place no longer feels fit for habitation.”

Ruchi, who lives in Tutu on the outskirts of Shimla, also shifted to another rented house after repeated monsoon scares. Her previous home stood beside a seasonal stream, and every spell of heavy rainfall made her anxiety worse.

“Whenever I saw news reports of rain-related disasters, I became anxious. Watching the water level in the stream rise only intensified that fear,” she says.

Although she still worries during the monsoon, moving to a different neighbourhood has eased the constant panic she once experienced.

Mental health remains missing from disaster response

Himachal Pradesh has made significant progress in recognising the health risks posed by climate change. The state has adopted the State Action Plan on Climate Change and Human Health (2022–27) and established a Climate Change and Human Health Cell to strengthen public health preparedness.

The plan focuses on physical health, disease surveillance, healthcare infrastructure resilience, early warnings and logistics, but does not address mental health support or psychological care for disaster-affected populations.

While the Climate Change and Human Health Cell provides training to healthcare workers and Accredited Social Health Activists (ASHAs) on mental health and psychological first aid, experts say these efforts have yet to translate into meaningful support on the ground.

Dr Sanjay Pathak, former Director of the Himachal Pradesh Mental Health Authority, believes disaster management continues to prioritise physical rehabilitation over psychological recovery.

“Government responses after disasters understandably focus on relief and rehabilitation,” he says. “But very little attention is paid to what kind of psychological intervention survivors require. Unless mental health becomes an integral part of disaster response, people will continue to live with a persistent sense of insecurity.”

Dr Dutt points to another challenge: the severe shortage of trained mental health professionals.

“The frequency of disasters is increasing much faster than our capacity to provide psychological support. For now, community and family networks are helping people cope. But as those social structures weaken, the need for professional mental health services will become much greater.”

The policy gap extends beyond Himachal Pradesh. An analysis published by the Observer Research Foundation (ORF) notes that disaster management strategies in India remain largely centred on rescue operations, rehabilitation and rebuilding infrastructure, with mental health support yet to be systematically integrated into these frameworks. The analysis also found that psychological disorders following natural disasters are 40 per cent more common than physical injuries — underscoring the need to treat mental health as a core part of disaster preparedness and recovery.

What needs to change?

Both Dr Pathak and Dr Dutt agree that psychosocial care must become a standard part of emergency relief rather than an afterthought. They identify three immediate priorities: training schoolteachers to provide basic psychosocial support to children affected by disasters; strengthening the capacity of ASHA workers and frontline health personnel to identify and respond to psychological distress; and expanding access to counselling and mental health services in disaster-affected communities.

For a Himalayan state facing ever more frequent extreme weather, integrating mental health into disaster management is no longer simply a public health recommendation — it is a necessity.

As climate change continues to reshape the mountains, it is also reshaping the emotional landscape of the people who call them home. The landslides and floods may disappear once the rains recede, but for many survivors, the fear remains — returning every monsoon, long before the first cloudburst.

Delhi’s Air Pollution: Climate Change Is Raising Risks for India’s Heritage

India’s heritage sites are facing growing environmental risks as air pollution, rising temperatures, changing rainfall and coastal exposure accelerate the deterioration of historic structures. From pollution-linked black crusts at Humayun’s Tomb to salt damage at Mahabalipuram’s Shore Temple, scientific studies show why climate and environmental monitoring are becoming increasingly important for heritage conservation.

Delhi’s air pollution is damaging more than the city’s air quality. It is also contributing to the slow deterioration of its built heritage. India’s historic monuments are facing an environmental threat that extends beyond age and neglect. Air pollution, extreme weather, changing rainfall, rising temperatures and coastal hazards are creating new challenges for conserving structures built under very different environmental conditions.

A new study of Humayun’s Tomb in Delhi provides a close look at one of these risks. Researchers from IIT Roorkee and IIT Kanpur found that air pollution is contributing to the formation of black crusts on the sandstone surfaces of the UNESCO World Heritage Site. The study found that these crusts contain gypsum, carbon-rich material and traces of metals associated with urban pollution.

The finding is significant because it shows how environmental conditions around a monument can gradually alter its materials. But Humayun’s Tomb is only one example of a wider conservation challenge.

Pollution Leaves a Chemical Mark

Researchers collected five black-crust samples from rain-sheltered rooftop locations at Humayun’s Tomb under the supervision of an Archaeological Survey of India conservator. Using techniques including XRF, XRD, FTIR, SEM-EDX, CHNS and ICP-MS, the researchers found gypsum to be the dominant mineral in the crust. They concluded that external sources of calcium, including airborne particles, react with sulphur compounds to produce gypsum on the sandstone.

The composition also contained indicators consistent with pollution from vehicles, road and soil dust, construction, biomass burning and industrial activity. Crust formation was stronger at locations exposed to wind but sheltered from rain, showing that both pollution and local exposure conditions influence deterioration.

The study does not establish that the black crust itself has caused structural failure of Humayun’s Tomb. Instead, it identifies a long-term material deterioration process and recommends preventive conservation, including scientifically established cleaning methods, site-specific testing of protective coatings, air-quality monitoring and atmospheric modelling.

The Taj Mahal Shows How Pollution Affects Heritage

Humayun’s Tomb is not the only Indian monument where air pollution has been studied as a conservation concern. A 2015 study in Environmental Science & Technology measured particulate pollution around the Taj Mahal over a year and found high levels of light-absorbing particles, including black carbon, brown carbon and dust. Experiments using marble surrogate surfaces showed that these carbon-rich particles contribute to surface discoloration.

However, this finding is specific to staining and surface change. It does not imply that air pollution alone explains all forms of deterioration at the Taj Mahal. Recognising pollution as a conservation issue, the Ministry of Culture reports that the Archaeological Survey of India operates air-pollution monitoring laboratories at the Taj Mahal and Bibi ka Maqbara.

Climate Conditions Monuments Face

Climate change presents a different, but overlapping, conservation problem. UNESCO identifies storms, cyclones and tidal surges as potential threats to the World Heritage property and notes that their frequency could increase as a result of climate change.

A major review of climate-change impacts on cultural heritage found that climate change can alter the frequency and intensity of processes that already damage historic materials. These include moisture-related deterioration, salt crystallisation, biological growth and erosion. The review stresses that the effects vary according to the material, location and local climate of each heritage site.

That makes it important not to treat climate change as a single threat to India’s monuments. A stone temple on the coast faces different risks from a sandstone monument in Delhi or a heritage structure in a flood-prone region.

Mahabalipuram: Salt and Sea Exposure

The Shore Temple at Mahabalipuram illustrates the vulnerability of coastal heritage. A study by researchers from ASI and the National Museum Institute examined the deterioration of the 7th–8th-century granite monument. Extensive salt-induced deterioration, particularly on sections directly exposed to the sea. Some sculptures on the seaward side had been eroded beyond recognition.

The study linked the deterioration to marine exposure, sea spray, soluble salts, high-velocity winds and the site’s tropical, humid conditions. The researchers also found that continuous sea spray makes some conventional stone-conservation approaches difficult to maintain.

The study does not establish that climate change caused the Shore Temple’s existing deterioration. It does, however, demonstrate how vulnerable coastal heritage can be to marine and climatic conditions; risks that become increasingly important as coastal environments change.

Importance of Preventive Conservation

India has already begun incorporating environmental monitoring into heritage conservation. The Ministry of Culture said in that ASI and ISRO have installed Automated Weather Stations at several historical monuments to track temperature, rainfall and wind. ASI also carries out periodic scientific treatment and conservation work at heritage sites.

But the evidence from Humayun’s Tomb shows that monitoring pollution and climate variables must be paired with material-level studies. The challenge is identifying the environmental drivers of deterioration and intervening early, before it becomes irreversible.

For Delhi, this means reducing pollutants that settle on historic stone. Coastal monuments must contend with salt, moisture and erosion, while high-rainfall regions require stronger drainage and structural resilience.

Climate-Resilient Agriculture Must Move From Policy to Practice

Climate-resilient agriculture is emerging as a key policy priority in India as experts call for water conservation, crop diversification, and technology-driven farming to tackle growing climate risks.

Climate-resilient agriculture is gaining policy attention in India as experts advocate water conservation, crop diversification, and digital technologies to help farmers adapt to increasing climate risks and strengthen long-term food security.

As climate change continues to threaten agricultural productivity through erratic rainfall, rising temperatures and increasing water stress, experts have called for stronger evidence-based policies and investments in climate-resilient farming to safeguard India’s food security and rural livelihoods.

The discussion took place at a workshop organised by the Nation First Policy Research and Change Foundation (NFPRC) for Members of Parliament and State Legislators in New Delhi, where policymakers, agricultural scientists and researchers examined strategies to strengthen climate resilience across India’s farming sector.

“Our focus must be on evidence-based policymaking, climate-resilient governance, crop diversification, water conservation, irrigation and insurance coverage to strengthen India’s agricultural resilience,” Tarun Chugh, Member of Rajya Sabha and Chairperson of the NFPRC Foundation, said while inaugurating the workshop.

During a technical session, Praveen Kumar Singh, Agriculture Commissioner at the Ministry of Agriculture and Farmers Welfare, and Rajbir Singh, Deputy Director General at the Indian Council of Agricultural Research (ICAR), emphasised that adapting Indian agriculture will require region-specific crop diversification, wider adoption of millets, pulses, oilseeds and horticultural crops, along with investments in watershed development, rainwater harvesting, groundwater recharge and micro-irrigation.

Experts also highlighted the growing role of emerging technologies, including artificial intelligence, drones, Internet of Things (IoT) devices and digital supply chains, in improving weather forecasting, precision farming, irrigation management and crop insurance delivery. Speaking on agricultural innovation, Ramesh Chand, Distinguished Professor at the Indian Council for Research on International Economic Relations (ICRIER) and former Member of NITI Aayog, said technology, finance and governance must work together to build a more resilient agricultural system.

The workshop concluded with a call for closer collaboration between policymakers, scientific institutions and farming communities, underscoring that climate resilience will depend not only on technological innovation but also on translating research-backed policies into effective action at the farm level.
