Mumbai Faces Sharper Monsoons, Rising Heat: Report

A report by the Azim Premji University warns Mumbai could see 16.8 percent rise in southwest monsoon rainfall by 2040. Mumbai: The city could witness a 16.8 percent increase in southwest monsoon rainfall by 2040, according to a climate crisis report released by the School of Climate Change and Sustainability at Azim Premji University.

Mumbai Faces Sharper Monsoons, Rising Heat: Report

A report by the Azim Premji University warns Mumbai could see 16.8 percent rise in southwest monsoon rainfall by 2040. Mumbai: The city could witness a 16.8 percent increase in southwest monsoon rainfall by 2040, according to a climate crisis report released by the School of Climate Change and Sustainability at Azim Premji University. The report, titled Indian Coastal Region: Climate Protection 2021–2040, was discussed on Friday during a session led by scientist and professor Santonu Goswami. The study examined the growing impact of climate change on citizens, ecosystems and traditional livelihoods across India’s coastal regions. The report states that suburban Mumbai is projected to experience summer maximum temperatures rising by 1.3°C by 2040, alongside intensified monsoon activity and longer periods of heavy rainfall. Researchers estimate that the city could face almost an additional week of intense rain during the monsoon season. Wider Shifts The findings also point to wider climatic shifts across western India. Surat and Bhavnagar in Gujarat are expected to witness southwest monsoon surges of 23 percent and 24 percent, respectively. According to the report, rising wet-bulb temperatures - a measure combining heat and humidity that determines the body’s ability to cool itself through sweating - are already making several regions increasingly vulnerable. Researchers warned that traditional knowledge systems, including Kerala’s Nakaih wind calendar, are becoming unreliable because of erratic weather patterns. “The window for adaptation is rapidly narrowing,” said Goswami, warning that the 1.5°C warming threshold could soon be reached across India’s administrative regions. The report highlights a range of climate threats facing coastal India, including rising temperatures, dangerous wet-bulb heat, intensified west coast monsoons, sea-level rise, coastal erosion, salinity intrusion, cyclone risks and growing public health concerns. Traditional livelihoods are also under strain. Members of Mumbai’s Koli fishing community have reported business losses as unpredictable rainfall disrupts the traditional drying of prawns. Goswami stressed the need for accessible climate data to strengthen local resilience planning. “Climate data democracy is essential for climate action. We are in the middle of a data tsunami. Yet we are not at a stage where anyone interested can readily download data,” he said. He added that governments, policymakers, journalists, students and activists would all play a crucial role in driving climate action. Anurag Behar, CEO of the Azim Premji Foundation, said climate change was no longer a distant concern. “Climate change is not some distant future challenge but the reality of today. 2040 is just 14 years away,” he said. Shashwat DC, Head of Research Communications at the School of Climate Change and Sustainability, called for urgent investment in climate-resilient infrastructure. “We need to think about our infrastructure for some time. We need a discussion on climate resilient infrastructure,” he said. He further noted that the climate crisis disproportionately affects daily wage labourers and gig workers, who remain among the most vulnerable to extreme weather events.

Bad Roads, Ugly Politics


The pathetic state of roads in Mumbai city as well as its suburbs has made daily commute a dangerous affair. The residents are miffed with the BMC over its lackadaisical attitude. Mumbaikars tweet photos, post videos to grab attention, but everything is in vain. Who cares for the common people. Backbreaking journeys have become part and parcel of life. Political leaders are busy mud-slinging.


This year the monsoon took a break after almost four and half months. During this time some of the roads virtually became non commutable. It may be recalled that the Chief Minister Eknath Shinde first announced to make Mumbai roads pothole free.


Its almost two years now the BMC has concretised only 9 percent of roads it planned to concretise. This decision was taken when it came to light that due to the properties of bitumen in asphalt roads, potholes are a regular occurrence due to contact with water during monsoons.


Hence, to solve the problem of potholes, the corporation has adopted a policy of cement concreting of 6-meter-wide roads in phases. The decision was taken but the dilly-dallying affair made things more difficult.


Mumbai’s traffic does put a lot of strain on roads which is not the case in the other developed countries. Second most important aspect is concretisation of roads is done partly and in phases.


The worst problem which is faced is repeated digging for cables and drainage, which weakens the roads. Above all corruption in BMC makes matters worse as a result everything comes to grinding halt.


According to experts, repairing potholes is a reaction with symptomatic treatment. By and large we are dispensing superficial treatment without addressing the root cause. The long-term solution will be to have roads with no potholes but what we need is the means and technology to achieve this. But for this political will is necessary which we lack on every step.


Mumbaikar’s are convience that corruption in the municipal corporation is the main reason. Contractors have had a monopoly over the last 20 years and this is the reason why reputed companies never come ahead for these projects.


As a result, in the name of attendance and repair, the BMC does shoddy work. Crores are spent but the end result is nothing. The BMC is not paying attention to the crust. If the crust is weak, potholes will see an increase. Without any thought or technical know-how, potholes are filled with cold mix.


This is the reason why the city and suburbs continue to have craters on the roads.


Craters, a serious threat to the safety and security of people. Mumbaikars fade up from their repeated visits to orthopedic surgeons.


They are in a mood to teach a proper lesson to those who were at the helm of the affairs.
