There is just not a lot romance left for the rain in India’s cities. When an aged couple in Mumbai not too long ago recreated the basic Rim jhim gire sawan from Manzil (1979) in a video that went viral, the viewer response was largely marked by nostalgia for a special, “simpler” time. The nation’s burgeoning city areas have gotten more and more susceptible to floods and their path of misery – snapped energy traces, accidents, drowning automobiles and dying in waterlogged underpasses.

Experts and concrete planners have emphatically recognized unchecked improvement and altering climate patterns as the key triggers of city flooding in India. The preparedness, nonetheless, has not stored tempo, both with these local weather variations or the speed at which the city inhabitants is rising in India; it will likely be 43.2 per cent by 2035, in response to the United Nations.

Last week, water ranges within the Yamuna river rose to an all-time excessive, flooding a number of areas in Delhi. Earlier this month, floods hit Mumbai, in what has change into an annual monsoon occasion right here and in cities like Ahmedabad and Gurugram.

A report by the Comptroller and Auditor General stated the 2015 floods in Chennai, which left 289 individuals lifeless, had been attributable to “heavy rains coupled with multiple failures on the part of various government agencies”. It censured the state authorities for ineffective dealing with of encroachments that hampered flood mitigation work.

In 2022, Bengaluru acquired extreme rainfall – 132 mm on September 5, about 10 per cent of the seasonal rainfall in sooner or later – that inundated many components of the town. The affect of an uncommon climate occasion was aggravated by poor in-built resilience, a cumulative results of inept planning over a long time.

The cities are in “a tough place”, as they grapple with the dual challenges of getting to accommodate a rising inhabitants in addition to meet its demand for bodily infrastructure which, in flip, is leaving them unprepared for climate occasions, even regular rainfall, says eminent local weather scientist Prof J Srinivasan. “In Bengaluru, even if it rains 50 mm, there is flooding. You cannot always blame the monsoon. Our urban areas have not been managed properly. The inescapable fact is that our population has gone up and there are new demands,” says the Distinguished Professor on the Divecha Centre for Climate Change, Indian Institute of Science.

The problem will get extra advanced with aberrant local weather patterns.

As one other spherical of monsoon rain derails life in lots of cities and cities in northern India, urbanists reiterate the necessity for complete methods to make India’s cities extra flood-resilient. The argument is for changing the chorus of fatalism – “we can plan only so much for nature” – with one in every of resolve and inventiveness, to deal with what is basically a man-made drawback. The shift has to run on insurance policies that encourage innovation and are complemented with options outdoors of the normal gray infrastructure which constitutes human-engineered programs like stormwater drains and pipelines. They additionally underline a brand new method to post-flooding evaluation that goes past mere stock-taking of damages and helps devise long-term contingency plans.

The cycle of disruptions set off by urbanisation leads as much as floods in acquainted patterns, throughout India’s cities. An increase in inhabitants means a lack of pure infrastructure, shrinking water our bodies, development in low-lying, susceptible areas, and encroachment of already brimming, poorly-maintained drains. More roads and pavements imply restricted percolation of rainwater and consequently, elevated stormwater runoff.

Urban planning now entails larger engagement with science. The hole between know-how and implementation on the bottom, nonetheless, is within the overlapping of duties taken up by totally different authorities businesses and the resultant lack of collective accountability. Individual domains like land improvement, roads and water provide are serviced by a number of businesses, leaving nobody accountable for the general supply of the service, particularly within the metros.

Owning up, regionally

The Union Ministry of Housing and Urban Affairs (MoHUA) has been selling using info and communication know-how, by introducing the Integrated Command and Control Centre (ICCC) for centralised administration of city infrastructure to assist cities make evidence-based selections.

“Currently, 75 cities have an operational ICCC for various municipal services including water supply and flood monitoring,” says R Srinivas, who has led the Metropolitan and Union Territories division of the Town and Country Planning Organisation underneath MoHUA.

Urban Local Bodies (ULBs), in the meantime, are struggling with out fiscal autonomy to fulfill the evolving infrastructure challenges. Abhinav M, an city planner and researcher in water and sanitation, inexperienced infrastructure, and psychological well-being, highlights the problem of various stakeholders enterprise programmes which have frequent water-resilience targets – lake improvement authorities, firms and municipalities, water provide our bodies, air pollution management boards and different state businesses. He sees structural, policy-level modifications as vital for constructing resilient cities.

“Decentralisation and devolution of powers to the ULBs is the way forward. These agencies are more connected to the community but it is the government that retains the power to decide on local planning. The ULBs should be financially empowered (to independently envision and undertake projects),” says Abhinav, Senior Associate, Urban Practitioners Programme (UPP) on the Indian Institute for Human Settlements (IIHS).

The UPP collaborates with public sector functionaries in key establishments for coaching in city water provide and sanitation, geospatial know-how, constructing resilience to local weather change and catastrophe danger discount. 

The United States Trade and Development Agency and KPMG estimate that flooding attributable to heavy rains between 2005 and 2015 value Mumbai Rs 14,000 crore. In Bengaluru, the Outer Ring Road Companies Association estimated a collective lack of Rs 225 crore for corporations situated on the highway, from sooner or later of heavy rainfall final yr – August 30.

A nationwide survey by LocalCircles, the outcomes of which had been launched this month, had 58 per cent of the respondents say that their metropolis/district will get “quite badly waterlogged” in the course of the monsoon season and 36 per cent say that they had been “somewhat affected” by the waterlogging. The survey acquired a complete of about 22,000 responses from residents in 293 districts; 48 per cent of the respondents had been from tier 1, 33 per cent from tier 2, and 19 per cent from tier 3 and 4 districts. 

Among the respondents impacted by waterlogging, 84 per cent indicated that they spent “much more time” in visitors and 64 per cent stated they misplaced work hours/productiveness. The respondents additionally confirmed car put on and tear and associated prices (68 per cent) and elevated danger of accidents (68 per cent).

New shades of development

“There cannot be an absolute dependence on engineered grey solutions. These are expensive and, on their own, are likely to fail in the face of intense rainfall events. Combining these with the blue-green solutions (to develop parks, wetlands, green roofs, and permeable surfaces) will make mitigation strategies more flexible,” says Sahana Goswami, Senior Programme Manager – Water Resilience, at World Resources Institute (WRI) India.

Blue-green infrastructure is a complementary community of water our bodies like rivers and canals, and inexperienced elements like parks and forests, designed to enhance city flood resilience.

In a WRI India working paper printed in January this yr, Goswami, together with Samrat Basak, Aakash Malik and Raj Bhagat Palanichamy studied the connection between built-up growth in 10 cities from 2000 to 2015 and the modifications it dropped at their blue-green infrastructure, similar to floor water, inexperienced cowl, and recharge zones.

Remote sensing knowledge and satellite tv for pc imagery had been used to trace the modifications. The examine stated vital components of latest improvement in most of those cities had been sited on excessive and really excessive recharge potential zones – Delhi (66 per cent), Bengaluru (64 per cent), Kolkata (54 per cent), Chennai (49 per cent), Surat (45 per cent), Ahmedabad (41 per cent), Jaipur (15 per cent), Hyderabad (14 per cent), Pune (14 per cent), and Mumbai (11 per cent).

Systemic points, protracted administrative processes and the advanced economics of land improvement have restricted the vary of options. Goswami says no system in place permits innovation in figuring out options. “For the city authorities, there is no incentive to try out innovation at scale,” she says.

Unchecked improvement can be linked with the absence of the proper incentives. “The planning authorities who design their cities’ master plans should be working with ideas to ensure integrated, holistic development but they are, instead, incentivised for sprawl. The private players are also focused on development outside of the core city areas where infrastructure, including water supply, is a problem,” says Abhinav.

The undermining of the individuals’s company is a bigger subject. Here, Abhinav distinguishes between the accountability of mayors in some cities within the West, straight elected by the individuals for a hard and fast tenure, and that of mayors in India, who don’t wield the powers of state-appointed Municipal Commissioners.

Srinivas says it’s time cities developed technology-powered resilience and preparedness for flooding. “Municipal corporations need to prepare GIS (Geographic Information System)-based master plans, which can accordingly delineate areas vulnerable to urban flooding,” says Srinivas.

Cities additionally want to organize their respective catastrophe administration plans, he provides. “These should focus on pre-disaster preparations so that infrastructure like stormwater drains, sewer lines and roads can be protected and the damage can be reduced to the minimum.”

Solutions from nature

In cities the place the adoption of primary sustainable practices like rainwater harvesting has not caught on, nature-based options have began to seek out the directors’ endorsement. 

The Delhi Development Authority’s Master Plan 2041, as an example, has the enhancement of blue-green infrastructure as a precedence space. The technique covers the event of inexperienced buffers alongside drains, repurposing of landfills, underutilised websites and wastelands, incentivising inexperienced roofs, and greening of streets and areas underneath flyovers.

The Brihanmumbai Municipal Corporation’s Mumbai Climate Action Plan incorporates methods in direction of a Net Zero and climate-resilient Mumbai by 2050.

Abhinav says it is a good time to start out speaking about inexperienced options however these are additionally, primarily, western ideas that should be tailor-made for Indian cities.

The challenge tendering system in India’s cities is skewed in direction of the adoption of gray infrastructure, factors out Goswami. “A shift to solutions like bioswales (vegetated channels that move stormwater runoff) or rain gardens is yet to happen,” she says.

Mitigation methods have been restricted both to piecemeal initiatives for the monsoon months or bigger, resource-intensive programmes which might be invariably delayed. There is change within the making, with extra city planning our bodies taking water-sensitive approaches in step with local weather motion, however these options are, nonetheless, within the early levels of adoption.
