India to witness 43% rise in extreme rainfall by 2030, 2.5-fold surge in heatwave days: Study

  
By Rajiv Shah 
A groundbreaking study released by IPE Global and Esri India has warned that India is on course to experience a 43% increase in the intensity of extreme rainfall events and a 2.5-fold rise in heatwave days by 2030. Titled "Weathering the Storm", the study paints a stark picture of the country becoming simultaneously hotter and wetter due to the accelerating impacts of climate change.
The research, launched at the International Global-South Climate Risk Symposium in New Delhi, reveals that metropolitan cities including Mumbai, Chennai, Delhi, Surat, Thane, Hyderabad, Patna and Bhubaneswar will see a twofold increase in heatwave days. Extended heat conditions are expected to drive more frequent and erratic rainfall events, with eight out of ten Indian districts likely to face such extremes by the end of the decade.
Data from the study indicates that between 1993 and 2024, India witnessed a 15-fold increase in extreme heatwave days during the March-to-September period, with a 19-fold increase recorded in the past decade alone. The monsoon season, too, has shown signs of transformation, marked by prolonged summer-like conditions and greater unpredictability in rainfall.
Lead author Abinash Mohanty, Head of Climate Change and Sustainability at IPE Global, stressed that climate extremes are set to intensify further with tier-I and tier-II cities bearing the brunt. "Around 72% of these urban centres are likely to face increased heat stress and rainfall extremes, accompanied by storm surges, lightning, and hailstorms. We must adopt hyper-granular risk assessments and establish climate-risk observatories to safeguard our agriculture, industry, and infrastructure,” he said.
The study identifies Gujarat, Rajasthan, Tamil Nadu, Odisha, Uttarakhand, Himachal Pradesh, Maharashtra, Uttar Pradesh, Meghalaya, and Manipur as particularly vulnerable, with over 80% of districts in these states projected to suffer from both heat stress and extreme rainfall events. Coastal districts are also at high risk, with 69% likely to experience extended summer discomfort by 2030, a figure expected to rise to 79% by 2040.
Ashwajit Singh, Founder and Managing Director of IPE Global, noted that the findings echo the recent global warnings on extreme heat. “Nearly all countries of the Global South, including India, must now grapple with improving living standards while urgently addressing climate threats. This study is a clarion call to act—leveraging innovation and preparedness to turn risk into resilience.”
The study also found a clear linkage between areas experiencing frequent heatwaves and those witnessing incessant rainfall, especially in the JJAS season. Many of these districts are undergoing a 63% change in land use and land cover, driven by microclimatic disruptions such as deforestation, mangrove loss, and wetland encroachment.
Agendra Kumar, Managing Director of Esri India, highlighted the critical role of geospatial tools in addressing climate challenges. “The intensifying climate extremes are no longer anomalies—they are now patterns. Geographic Information System (GIS) technology enables data-driven planning, infrastructure resilience, and public preparedness. We are committed to helping India and its institutions build a sustainable, climate-adaptive future.”
The study proposes several strategic interventions, including the establishment of a Climate Risk Observatory (CRO) for real-time monitoring and forecasting of chronic and acute heat and rainfall risks. It also recommends the development of risk-financing instruments and the appointment of heat-risk champions within district disaster management authorities to localize and accelerate mitigation efforts.
Offering a first-of-its-kind district-level assessment of heat and rainfall extremes in India, the study argues for more localized climate risk modeling. Global models alone, it says, are insufficient to address the complex and non-linear dynamics of climate change on the ground.
Using a dynamic ensemble of climate models and spatial analyses, the research presents projected scenarios for 2030 and 2040, offering empirical evidence of exposure to extreme events across India. It underscores that identifying, monitoring, and managing climate risks at a hyper-local level is not just a scientific imperative, but a developmental one.

History, culture and literature of Fatehpur, UP, from where Maulana Hasrat Mohani hailed

By Vidya Bhushan Rawat*  Maulana Hasrat Mohani was a member of the Constituent Assembly and an extremely important leader of our freedom movement. Born in Unnao district of Uttar Pradesh, Hasrat Mohani's relationship with nearby district of Fatehpur is interesting and not explored much by biographers and historians. Dr Mohammad Ismail Azad Fatehpuri has written a book on Maulana Hasrat Mohani and Fatehpur. The book is in Urdu.  He has just come out with another important book, 'Hindi kee Pratham Rachna: Chandayan' authored by Mulla Daud Dalmai.' During my recent visit to Fatehpur town, I had an opportunity to meet Dr Mohammad Ismail Azad Fatehpuri and recorded a conversation with him on issues of history, culture and literature of Fatehpur.

New RTI draft rules inspired by citizen-unfriendly, overtly bureaucratic approach

By Venkatesh Nayak* The Department of Personnel and Training , Government of India has invited comments on a new set of Draft Rules (available in English only) to implement The Right to Information Act, 2005 . The RTI Rules were last amended in 2012 after a long period of consultation with various stakeholders. The Government’s move to put the draft RTI Rules out for people’s comments and suggestions for change is a welcome continuation of the tradition of public consultation. Positive aspects of the Draft RTI Rules While 60-65% of the Draft RTI Rules repeat the content of the 2012 RTI Rules, some new aspects deserve appreciation as they clarify the manner of implementation of key provisions of the RTI Act. These are: Provisions for dealing with non-compliance of the orders and directives of the Central Information Commission (CIC) by public authorities- this was missing in the 2012 RTI Rules. Non-compliance is increasingly becoming a major problem- two of my non-compliance cases are...

Celebrating 125 yr old legacy of healthcare work of missionaries

Vilas Shende, director, Mure Memorial Hospital By Moin Qazi* Central India has been one of the most fertile belts for several unique experiments undertaken by missionaries in the field of education and healthcare. The result is a network of several well-known schools, colleges and hospitals that have woven themselves into the social landscape of the region. They have also become a byword for quality and affordable services delivered to all sections of the society. These institutions are characterised by committed and compassionate staff driven by the selfless pursuit of improving the well-being of society. This is the reason why the region has nursed and nurtured so many eminent people who occupy high positions in varied fields across the country as well as beyond. One of the fruits of this legacy is a more than century old iconic hospital that nestles in the heart of Nagpur city. Named as Mure Memorial Hospital after a British warrior who lost his life in a war while defending his cou...

Epic war against caste system is constitutional responsibility of elected government

Edited by well-known Gujarat Dalit rights leader Martin Macwan, the book, “Bhed-Bharat: An Account of Injustice and Atrocities on Dalits and Adivasis (2014-18)” (available in English and Gujarati*) is a selection of news articles on Dalits and Adivasis (2014-2018) published by Dalit Shakti Prakashan, Ahmedabad. Preface to the book, in which Macwan seeks to answer key questions on why the book is needed today: *** The thought of compiling a book on atrocities on Dalits and thus present an overall Indian picture had occurred to me a long time ago. Absence of such a comprehensive picture is a major reason for a weak social and political consciousness among Dalits as well as non-Dalits. But gradually the idea took a different form. I found that lay readers don’t understand numbers and don’t like to read well-researched articles. The best way to reach out to them was storytelling. As I started writing in Gujarati and sharing the idea of the book with my friends, it occurred to me that while...

From seed to soil: How transnational control is endangering food sovereignty

By Bharat Dogra  In recent decades, the world has witnessed a steady erosion of plant diversity in many countries, particularly those in the Global South that were once richly endowed with natural plant wealth. Much of this diversity has been removed from its original ecological and cultural contexts and transferred into gene banks concentrated in developed nations. While conservation of genetic resources is important, the problem arises when access to these collections becomes unequal, particularly when they fall under the control of transnational corporations.
