“Who is responsible for this chaos?”
The question recently repeated all over the financial capital in Mumbai, India, where thousands of residents found themselves again They were cut off, soaked and frustrated.
The heavy rains brought the city to a dead end, and this was before the monsoons began in full swing. The roads turned into rivers, the vehicles were disrupted in the middle of the neighborhoods, and the water neighborhoods were shed within hours.
Even the newly built metro station was unable to withstand heavy rains, as the photos and videos of the station became immersed in viral muddy water.
Pre -Maron Flood revealed the fragile infrastructure in the city and sparked widespread anger on social media.
BMC Municipal BMC, one of the richest civilian organizations in India responsible for maintaining infrastructure in Mumbai, initially blamed the problem for clogging garbage and debris from the metro construction, The Hindustan Times reported.
After criticism, BMC installed water removal pumps in the flood -exposed areas and started manually removing waste from drains to prevent further skiing on the water. But for many population, the procedure came too late.
The crisis is not new – as it is not unique for Mumbai.
From Delhi in the north to Bengalu In the south, the largest city of India is flooded every seasonal wind season. Roads collapse, excessive banks, infrastructure are soaked and traffic stopped.
Experts blame rapid urbanization, bad infrastructure and years of environmental neglect as the root causes of this problem.

“The pace of urban expansion has exceeded the development of the supportive infrastructure, especially in water and sanitation systems,” says Deco Cokriga, an architect and urban scheme based in Delhi.
He adds: “Many cities depend on old systems designed decades ago. In the process of unrestricted expansion, natural drainage channels, wetlands and water bodies that were absorbed at some time, excess rain water was built or neglected.”
Experts say that there is no single solution that suits everyone, as each city faces unique challenges and factors such as geography, population and climate that must be considered when designing effective responses.
India receives 80 % of the annual rainfall during the seasonal wind season, which usually starts from June and continues until September.
The seasonal winds are crucial for agriculture and ways to live millions of Indian farmers. They depend on seasonal bathing in parts of the country where the appropriate irrigation channels are absent.
But experts say that climate change has made irregular weather – such as non -seasonal rain, sudden floods and droughts associated with severe heat – a more regular phenomenon, which directly affects millions of people.
The seasonal winds arrived this year a week before parts of southern India, where the authorities hunted unprepared.
“Depression was developed through the Eastern Eastern Arabian Sea, which had an effective role in withdrawing the monsoon wind stream,” says Mahaish Balawat, Vice President of Meteorology and Climate Change at SkyMet Prediction Company.
In Delhi, the Minto Bridge has become a symbol of the annual monsoon chaos of the city. Almost every year, after heavy rains, a bus or truck stumbles under the bridge – a picture that highlights the city’s struggle with urban floods.
This year, Delhi has registered the Arak Mayo since 1901, with more than 185 mm of rain, according to the Indian weather department.
Many residents have reported damage to their property.
At least four people were killed and dozens were wounded in one of the heavy storms that struck the city in May, according to media reports.
Meanwhile, in Bangaluru, more than 2000 km (1,240 miles) from the capital, the problem seems different but the root cause is the same.
Bangaluru, which was known for its network of lakes that helped manage excess rain water, has seen many of these water bodies. In their place, residential complexes, business and roads – leaving the city are vulnerable to floods.

“The Bengaluo consists of three main valleys through which the water flows naturally. Most of the city lakes are located in these valleys.”
These valleys were originally appointed as regions without construction, but over the years, infringement and changes later occurred in the law that allowed infrastructure projects in the region, he says.
“When you convert the lakes – which are traditionally operating as temporary warehouses for floods – into built areas, the water has no place to go to. So, what we see in Bangaluru today is the result of poor urban planning.”
Mr. Brasad notes that Bangaluru, who sits over a hill, was not intended to note that the current situation is completely man -made.
It says that the violations of the construction, especially the construction that narrow or build the waters of storms, made matters worse.
Meanwhile, Mumbai faces natural challenges because of its geography. For example, many parts of the mobay are low and close to the sea, making them more vulnerable to floods during heavy rains, tide and high islands.
But experts say they are human actions that have made things much worse: reducing the mangroves, which usually work like natural barriers against floods, and build on the floods where water is supposed to drain.
“The collapse is a systematic – it begins with planning, which is often not explained by future climate variables, abandons poor implementation and is aggravated by the enforcement of weak regulations,” says Mr. Koukraga. “Political will is often a reaction – response to disasters rather than investing in long -term flexibility.”
This is not just a big city problem. Small cities often suffer equally, if not more.
During the weekend, At least 30 people died In the northeastern states of India, after heavy rains, floods and landslides. Tens of thousands were affected by the rescue efforts.
So, can anything to prevent this?
Yes, Mr. Kukreja says, but only if it is part of a long -term coordinated strategy.
It is proposed to use the maps and sensors in the actual time to identify high -risk areas and alert societies. Prediction models can also help authorities plan better responses.
“But technology alone is not a solution, as it needs its association with responsive governance and the participation of society,” he said.
For the cities of India to bear rain, they need more than just removing pumps and rapid repairs. They need to be planned to think forward, before the damage occurs.
