Mumbai, July 4 (Thomson Reuters Foundation) – As the Monsoon rains flood Mumbai each year, India's financial hub is flooded with flood media feeds, from Venetian gondola on the devastated streets of the city to salaried men commuting inflated and dingy. Notice.
This year, the institute wants social media to play a more practical role. That is, ask residents to tweet details about floods in their neighborhood and use that data to actually issue a geographically specific flood alert. -time.
"We can't monitor floods throughout the city ourselves, so we thought about getting the help of the community," said the head of the Climate Research Division at the Indian Institute of Technology Bombay behind it. Said Subimal Ghosh. Initiative.
In countries such as Australia and Indonesia, climate researchers around the world are increasingly monitoring meteorological events such as floods using data collected via social media.
They state that the data can be used to improve emergency response and rescue operations and make predictions more accurate. This becomes increasingly important as climate change contributes to extreme weather events.
"We need a participatory model for climate adaptation because we will be hit by more extreme rainfall events in the near future. Google Maps will show red for traffic. So you will be able to see real-time floods, "Ghosh said.
India's financial capital on the Arabian Sea coast is defined as "extreme" precipitation of more than 200 mm (7.9 inches) in 24 hours, about 12 times between 2017 and 2017. We recorded the amount of rainfall. In 2021, citizen data shows.
This is twice the number of such events in the last five years.
The IIT-Bombay project, launched just before the Monsoon in June, will use a digital elevation map showing the height of the area above sea level, spatial rainfall data, and tweets from local residents.
For example, a tweet that mentions "ankle depth" or "knee depth" water is an automated system that attempts to extract flood depth and location information. Is collected from Twitter using. they.
This is used to provide real-time flood information for the entire city displayed on the portal.
For example, "the area where water needs to be pumped first, how to control traffic, how people get home". Gauche said.
"Cities need a resilience plan," he told the Thomson Reuters Foundation.

Low-income neighborhoods
South and East Asia are at risk of flooding 1.6 billion He said that nearly 1.36 billion of the people live.

Low-income areas are even more affected by floods, especially in populous cities like Mumbai. I have received it. Living in an informal settlement, a World Bank report states that it points to poor drainage and land-use locations, nning as an important factor.
The city launched a flood forecasting system two years ago and installed a large drainage pump in the lowlandshttps://longreads.trust.org/item/Mumbai-C40-cities-network,モンスーンの時期には、建物の倒壊や地滑りなどの暴風雨関連の災害がよく見られます。

"Floods are an unavoidable reality and flood damage cannot be minimized," said New Delhi-based energy. Prasoon Singh, Head of the Global Environment Research Center at the Institute of Resources, said. Laboratory (TERI).
"(But) crowdsourcing information helps to validate forecasts, fine-tune forecasts, and improve rescue and rescue operations," he said, information gathered on social media. Added that it can also be fed to historical datasets.
In the short term, Mr. Gauche said he hopes that the Mumbai project will help urban residents to carry out their daily work, even during the monsoon season.
"My daughter was at school when it started to rain and the bus got stuck on a flooded road. All my parents were worried and went to school through a flooded road. I didn't know how to get there, "he said.
"Real-time information is important."
