Smart Cities 2.0: Integrating Public Transport Solutions And Urban Design

0

  • Accessibility should be the defining factor in integrating urban design with public transport solutions, as they result in the reduced use of private vehicles, facilitate enhanced economic activity, and ease the stress on the environment.

The Smart Cities Mission, one of the many flagship projects of the National Democratic Alliance (NDA) government, is set to complete four years later in June this year. In Prime Minister Narendra Modi’s own words, the process of urbanisation was to be seen as an opportunity and not an obstacle in the path towards country’s economic growth.

The government, in strategy, does not restrict itself to any standard definition of a ‘smart city’, and rightfully so. Given how each city is different with respect to its population, culture, and economic and commercial centres and prospects, having a one-size-fits-all approach for smart cities would be as meaningless as hoping for every constituency in every state to manufacture nothing but smartphones.

When it comes to the process of urbanisation, the government has its heart in the right place. Mainly, the Smart Cities Mission aims to revamp the core infrastructure elements in any city, thus enabling better standards of living and enhanced commercial activity that drives urban growth.

Public transport finds mention as one of the 10 primary principles of infrastructure development. However, it takes into account a conservative perspective where the focus is only to help public transport solutions exist, leaving their efficiency to time and technology solutions.

For long, the idea of using public transport in India has been confined to reducing traffic in a hope to eliminate congestion from city roads but without any success. While the government has been swift in adding more public transport projects and buses for commute within cities and states, the rising number of private vehicles has added to the stress on the streets, proving to be a major hindrance to the idea of smart urbanisation.

According to a 2017 report on public transport solutions by KPMG, India’s public transport must complement its urban population growth, which is all set to host 40 per cent of the population by the end of the 2020s with its contribution to the gross domestic product (GDP) being more than 70 per cent.

To host this rush to the economic centres of the country, the Ministry of Housing and Urban Affairs would have to invest more than Rs 2,175,600 crore (US $333 billion) in roads and mass transit systems across the next decade.

This is where efficient public transport solutions become vital in the grander scheme of urban design and development. As seen in the case of the National Capital Region (NCR), pollution can dampen any growth prospects.

Lately, the government has been successful in creating infrastructure, like the Eastern and Western Peripheral Expressways. This has enabled the heavy vehicle traffic, mostly trucks passing through Delhi destined for other states, to bypass the city altogether, thus easing the traffic stress. However, even in its success, the solution has come too late, for the region is already suffering from the adverse effects of pollution.

There is nothing smart about a city without economic viability. Therefore, the 99 cities shortlisted by the NDA government would require not only infrastructure that enables them to be economically competitive and self-sustaining in terms of financial resources and employment but also transport solutions that act as a bridge between these centres and the 500 million people that will crowd them for work and residence.

For smart cities, along with economic centres, safe and secure residential spaces are also important. As seen in the real estate sector, construction of apartments and townships precede the existence of expressways or roads that connect them to the cities. The price of a home on the outskirts of any second-tier city like Chandigarh (chosen to be a smart city in the second round) depends on the connectivity it has to the commercial centre. Therefore, for a significant period, these real estate projects find no takers, even at a cheaper price.

Bengaluru, touted as the most tech-savvy city of India, has also failed to address this challenge. Concerning infrastructure, the city has grown leaps and bounds in the last decade, but the connectivity solutions have fallen way behind. While Bengaluru Metro may offer a ray of hope for commuters, it is going to be a work-in-progress for years before it can evolve as the first choice for most workers, as seen in NCR for people travelling to work to Gurugram and Noida from New Delhi.

For public transport and urban design, the government needs to think beyond congestion, too. While congestion helps urban developers reflect upon the time taken to get from one area to another, it talks nothing about the area. For instance, a seven-minute drive around the Rajiv Gandhi Technology Park in Chandigarh may feel far more convenient than a 70-minute car ride around Electronic City in Bengaluru.

However, it must be taken into account that the latter gets an urban worker in touch with better economic and commercial centres, both in terms of scale and quality.

For long, the biggest hindrance for people looking to switch to public transport has been accessibility.

study conducted by the World Bank on pedestrian accessibility offers some perspective. Comparing three major financial centres of the world – Beijing, New York, and London – the study provided insight into how setting up public transport was not enough.

Assuming that the average walkability of any worker falls in the range of 20-25 minutes, the commercial centre or job location in the city would have to be within this walkable range for a public transport solution to be successful. Else, people will resort to private vehicles.

For the three financial centres, data about accessibility within a 10- or 20-minute walking radius of a major public transit station (MPTS) was found. Even though Beijing had a more robust public transport infrastructure, New York and London were found to have a much higher number of job options as compared to Beijing within a 10- and 20-minute walking radius. A 10-minute commute from the nearest MPTS put New Yorkers close to over 220,000 job options. The number ranged around 140,000 for the ones in London while it was below 100,000 for the ones in China.

Interestingly, a 20-minute commute from the nearest MPTS put New Yorkers to as many as 1,600,000 job options, more than 360,000 options in London, and merely 180,000-odd in Beijing.

Taking commercial areas into account, a 10-minute walk from any MPTS put New Yorkers close to as many as 80,000 commercial centres while the same duration got commuters in Beijing to less than 10,000 centres. Extend the walk by another 10 minutes and New Yorkers could get to over 500,000 commercial centres while the ones in Beijing could only choose from 130,000.

The same phenomenon explains the rise of Connaught Place (CP) in New Delhi as the ninth most expensive business area in the world. Given how the area is accessible to commuters from Noida and Gurugram, along with other parts of the city via Delhi Metro, it enables people to get to many commercial centres within 10 minutes. Add another 15 minutes to the walk and commuters can get to the office of any ministry, thus making the area one of the success stories for urban design integrated with public transport solutions.

The same list that puts CP at ninth has Manhattan, New York, at sixth, the financial centre of Beijing at third, and London at second place in terms of annual rent. The skyrocketing rents reflect the exuberance in the economics of these centres.

Thus, accessibility should be the defining factor in integrating urban design with public transport solutions, as they result in the reduced use of private vehicles, facilitate enhanced economic activity, and ease the stress on the environment.

The centres in New York and London were ahead of Beijing in helping commuters get to their job prospects and commercial centres, as the land use was done keeping in mind the public transport infrastructure. While the government should look to replicate the success of CP across smart cities in India, the urban design should be integrated with many MPTSs. For instance, high-density land use with commercial centres built in and a dense network of secondary roads for a pedestrian-friendly environment. A successful case study here would also be Cybercity in Gurugram with its metro station, Cyber Hub.

Speaking to Swarajya, Akash Passey, Senior Vice President, Volvo Bus Corporation, emphasised on rethinking urban development to align it with the idea of getting more people to use public transportation. ‘The efficiency of an urban design must be measured for how well it inculcates accessible, economical, and flexible modes of public transportation’, he added.

Going forward, the government has to go beyond the rhetoric of ‘smart’, ‘tech’, and ‘electric’ to get people to use public transport. Given that an average commuter cares more for their time in the morning than the carbon emissions in the atmosphere, the onus will lie on the government to get people to use transport solutions that are not environment-friendly alone but also economical and time-friendly.

Smart cities must be ranked not only for how clean they are on the ground but for the integrated urban design and transport that enables a cleaner city atmosphere, a move that will negate the probability of another gas chamber like New Delhi.

The NDA government after 2019, if at all, should introduce Smart Cities 2.0 that goes beyond core infrastructure elements and takes into account the bridge that connects economics and public travel for smarter living in cities.

In the film Margin Call, one of the better fictional recounts of the 2008 Lehman Brothers crash, Stanley Tucci, essaying the role of a risk management officer, breaks into a mathematical monologue about a 912-foot bridge he built once over the Ohio River. Used by 12,100 people each day, the bridge reduced 35 miles of driving on each side, thus eliminating 847,000 miles of driving a day or 25,410,000 miles a month, or 304,920,000 miles a year.

In existence for 22 years, Tucci recites how at an average speed of 50 miles per hour (~80 kilometres per hour), the bridge saved the communities on both sides of the drive 1,531 years of their life not spent in a car. The Smart Cities 2.0 requires many such bridges that connect public transport solutions and urban design.

45-Km Phase-1 Of Chennai Metro Will Be Fully Operational As 9.5-Km Washermanpet-DMS Stretch Opens By January-End

Metro Rail Safety Commissioner KA Manoharan, today (19 January), inspected the Chennai DMS-Washermanpet route, the last stretch of 45-km Phase-1 of Chennai Metro that is set to be thrown open to the public by the end of January.

The commissioner inspected the track, airflow, signal and other parameters this morning. The commissioner will also inspect the stations, the tunnel, passenger information system, public addressing systems, communication and telecom lines in the stations and station control rooms.

The 9.5-km underground line between Washermenpet and AG-DMS is the last leg of the 45-km phase-1 of the Chennai Metro and has eight underground stations including Washermenpet, Mannadi, High Court, Central, Government Estate, LIC, Thousand Lights, and AG-DMS. The stretch cuts through the city’s arterial Anna Salai.

Once 9.5 km line opens to the public, it will mark the completion of entire Phase-1 of Chennai Metro. Commuters will be able to reach airport from Washermenpet, in the northern part of city, covering 23.5 km in less than 60 minutes. A significant boost in the ridership in the network. is expected.

As of now, the stretches from AG-DMS to airport, Chennai Central to St Thomas Mount and Koyambedu to airport, totalling 35 km, are operational.

When the first 10-km metro service started, the ridership was 8,000 a day; up to 20-km, it was 12,000; up to 28-km, it was 18,000; and at 35-km, it was 55,000. The addition of another 10-km from AG-DMS to Washermenpet will multiply the ridership, said Pankaj Kumar Bansal, Managing Director, Chennai Metro Rail Limited (CMRL).

Bansal pointed out the example of Bengaluru metro, which saw a ridership of just 36,000 for a network of 36 km but when it was extended to 43 km, the ridership dramatically increased to nearly 3.5 lakh per day.

A 9-km stretch between Washermenpet and Wimco Nagar, which was announced as an extension of Phase-1 and on which work started in June 2016, is likely to be operational by June 2020.

CMRL is already working on Phase-2 which will have three stretches: Madhavaram to Siruseri; Light House to Meenakshi College; and Madhavaram to Shollinganallur, stretching from the IT corridor in the south of Chennai to the milk production hub in the north-west. The first portion of this phase will span 50 km and will connect Madhavaram to Koyambedu CMBT and Madhavaram to Sholinganallur. This phase is expected to stretch across 119 km and will have 116 stations. The project is likely to cost Rs 80,000 crore.

Seventy-five per cent of the funding for the Phase-2 has been firmed up with the Japanese funding agency. Soil testing is going on at various places and in a year, ground level work will begin. Thee 119-km network is expected to be operational by 2024.

Land acquisition process for the Rs 55,000 crore Maharashtra Samruddhi Mahamarg, also known as the Mumbai-Nagpur super communication highway, is now complete and funding has also been secured, reports Times Of India.

The highway is likely to be completed by December 2020, and will significantly reduce travel time between Mumbai and Nagpur to just eight hours. It currently takes about 14-15 hours to travel between the two cities.

Ground-clearing and levelling work has also begun at several stretches of the 701 km expressway.

“It’s a historic moment for us. Contractors have already started pre-construction works,” said Managing Director, MSRDC Radheshyam Mopalwar.

He added that 90 per cent of the farmers have already been compensated for their land. About 13 per cent of the land was acquired under the Maharashtra Highways Act, 1955, and compensation would be fully processed within the next few weeks.

“Men and machinery have taken over a major portion of the proposed expressway. Besides cleaning, grubbing and levelling roads, geotechnical investigations to decide the type and level of foundation are also in advanced stages. The construction plan profiles for 16 road phases are being given final touches. Site offices are being set up,” stated MSRDC Chief Engineer Anil Gaikwad.

The Ministry of Environment and Forests has already given a green-light for parts of the project which traverse forest zones, particularly near Nashik. A formal clearance too is expected in a couple of days.

A consortium of 20 banks led by the State Bank of India has promised to lend Rs 2.5 lakh crore loan for the project and another Rs 6,000 crore has been provisioned by state agencies.

Star Air, An Aviation Start-Up, To Soon Begin Flights From Bengaluru To Hubbali And Other Destinations

Star Air, an aviation sector start up, will begin its operations from 25 January under the Ude Desh Ka Aam Naagrik (UDAN) scheme. The company, backed by Sanjay Ghodawat Group, secured the rights to fly out from Hubballi to Tirupati, Hindon and Pune, Deccan Herald has reported.

Star Air has set the starting price of its tickets from Rs 1,299. The company has started booking for the flights on the Bengaluru-Hubballi and Hubballi-Tirupati routes. Prior to the addition of commercial flight operations in its portfolio, the company had already commenced air services through its helicopter services.

According to the report , the company received the Air Operator Certificate from the Ministry of Civil Aviation earlier this month. It will be the first scheduled commuter operator based out of Bengaluru’s Kempegowda International Airport.

“We plan to help Indian travellers connect to various locations at affordable rates and with the best of services,” Chairman of Ghodawat Group, Sanjay Ghodawat, was quoted in the report as saying.

The 50-seater Embraer ERJ145 fleet will be operated by the airline. Embraer is the fastest jet in its category and can fly at a 0.8 Mach Speed.

Under the UDAN scheme, underserved and unserved airports in remote parts of the country are being covered. The scheme offers exclusive traffic rights and subsidies to airlines which connect secondary and tertiary airports with major hubs in the country.

Why You Need To Take Vaclav Smil’s Views On Fossil Fuels And Energy Seriously

  • Why transition to renewables will be gradual, not exponential. Dr Vaclav Smil explores what the technical and other hurdles are towards moving to a fossil-free future.A look at the (new) renewables — solar, wind, biofuels etc.

Dr Vaclav Smil, a Distinguished Professor Emeritus at the University of Manitoba, Canada, and author of 30 interdisciplinary books and 500 papers is one of the big picture people and foremost thinkers on energy and environment.

Bill Gates, in his blog GatesNotes, called Smil his favourite writer and this has led to his popularity among science aficionados.

Here, I review a couple of books from his sprawling oeuvreEnergy Transition: History, Requirements, Prospects (2010) and Energy and Civilization: A History (2017).

In these books, Smil puts forward a startling thesis: In spite of recent proclamations of replacing fossil fuels with renewables in a decade or so, we are essentially a fossil fuel based civilisation and will continue to remain a fossil fuel based civilisation for 50 years more, maybe even a 100 years!

According to Smil there is a commonly held impression that the nineteenth century was the era of coal, the twentieth century was the era of oil and the twenty first century will be the era of renewables like solar, wind and biofuels. Contrary to that, the nineteenth century still belonged very much to the wooden era.

Between 1800 and 1900, Smil shows, biomass “provided no less than 85% of all of the century’s fuel energy”. The industrial revolution was, for major part, fueled by wood. Coal began to supply more than 5 per cent of all fuel energies around 1840 and this rose to one half by the beginning of the twentieth century.

Coal remained the world’s most important source of fuel energy until 1964, when its contribution was surpassed by crude oil. By 2000, coal and oil provided, respectively, about 25 per cent and 37 per cent of all fuel energies. In the twentieth century biomass (wood and dung) continued to supply about 20 per cent of the world’s fuel energy and natural gas supplied about 15 per cent.

This brings to Smil’s central argument in his aforementioned books: Energy transitions are long, complex and not easily amenable to simple generalisations and judgements. Such transitions take over two or three generations to occur.

Hence “it will be exceedingly difficult to restructure the modern high energy industrial and postindustrial civilization on the basis of non-fossil — that is, overwhelmingly renewable — fuels and flows”. In other words, it is highly unrealistic to expect a sudden transition to renewables anytime soon, certainly not within a decade.

The present generation is enamoured of Moore’s law — which states that computing power doubles every 18 months. People thus see accelerating growth in every sector. A case in point is Ray Kurzweil’s The Singularity is Near (2005) and Peter Diamandis and Steven Kotler’s Abundance (2012). According to this perspective, growth will accelerate at such a pace (exponentially) that, in a few years, society will be transformed beyond recognition.

Smil takes a stand against such unwarranted optimism. He categorically states that, in the energy sector, growth has been at the rate of 2-3 per cent every year for hundred years or so. And this trend will continue. That is why transitions to renewables will be gradual, not exponential.

What are the technical and other hurdles towards moving to a fossil-free future? Let us take a look at the (new) renewables — solar, wind, biofuels etc.

In 2010, photovoltaic electricity generation produced less than 0.1 per cent of the world’s electricity. Similarly, solar heating added less than 0.1 per cent of the global primary energy supply.

The costs of photovoltaics have been plummeting, but the costs of batteries, rectifiers, labour etc, have remained constant. Hence photovoltaic electricity is still more expensive than thermally generated electricity. Only through government subsidies does solar electricity become competitive.

Solar cells are produced by an arduous process that generates greenhouse gases and they are so toxic that, when the time comes for disposal and replacement of installed solar cells, they will prove to be a humongous problem.

And the other problem is intermittency; solar energy is available only in the daytime.

Intermittency is also a problem that bedevils wind energy. Wind is seasonal and cannot be predicted accurately. In case of very high winds, such as during storms and tsunamis, the windmills have to be shut down. In fact, there is a narrow wind speed window, in which windmills can be operated.

Furthermore, wind energy cannot totally free us from the fossil fuel addiction. Windmills need steel frameworks and the only economical process known to humanity to make pig iron (a precursor to steel) is smelting it in a blast furnace along with coke (obtained from coal).

Of course, steel can be recycled from scrap but that needs electric arc furnaces, the electricity for which comes from fossil fuels. And the plastic for making the giant blades of windmills comes from — guess what — oil and natural gas.

What about biofuels like biodiesel and bioethanol? Many countries embarked upon ambitious programmes to generate bioethanol from corn and sugarcane and biodiesel from jathropa. They claimed this would be completely carbon neutral.

They overlooked the fact that fertilizers would be required and use of fertilizers releases greenhouse gases (in the form of nitrous oxide). Furthermore, the only effective method of producing ammonia for nitrogenous fertilizers is via the Haber-Bosch process whose feedstock is hydrogen — produced from natural gas.

Fossil fuels in coal mines and hydrocarbon fields have power densities of 1-10 kW/ sq m. On the other hand, cultivation of phytomass (i.e. plants for biofuels) could average 1W/sq m. Thus “supplanting 12.5 TW of fossil fuels would require 12,500,000 km2, roughly the equivalent of the entire territories of the United States and India, an area more than 400 times larger than the space taken up by all of modern energy’s infrastructures” (italics in original), and where would we get the water for irrigation?

Consider the infrastructure invested in existing fuels. Smil states, “Coal and uranium mines, oil and gas fields, coal trains, pipelines, coal-carrying vessels, oil and LNG tankers, coal treatment plants, refineries, LNG terminals, uranium processing (and reprocessing) facilities, thermal and hydro electricity-generating plants, HV transmission lines and distribution lines, and gasoline and diesel filling stations constitute the world’s most extensive, and most costly, web of infrastructure that now spans the globe.”

Between 2000 and 2008, China more than doubled its coal extraction and it added almost 300 GW of coal-based electricity generating capacity. This represents an investment of the order of $300 billion. These plants will have to be operated for at least 30-35 years to be profitable.

Will China be willing to terminate this investment and turn to costlier and relatively unproven methods of electricity generation? Can the world afford to simply walk away from fossil infrastructure worth at least $ 15-20 trillion before these investments produce rewarding returns? Obviously not.

Given this state of affairs, can developing countries like India afford to limit its energy consumption to lower levels? In Energy and Civilization, Smil states that there is a correlation between human development and energy consumption. For securing adequate diets, basic health care and schooling and a decent quality of life, an energy use of 40-50 GJ/capita is absolutely required. An HDI above 0.8 could be achieved with 60-65 GJ/capita. An HDI > 0.9 requires at least 110 GJ/capita. “There is no discernable improvement in fundamental quality of life above that level,” states Smil.

In India, the energy supply is around 30 GJ/capita (less than the minimum of 40-50 GJ/capita) and HDI < 0.65. On the other hand, USA, Canada and Saudi Arabia have consumption of around 300 GJ/capita and an HDI between 0.8 and 0.9 (2015 data). Thus Smil advocates that while countries like India should be allowed to increase energy consumption, developed countries should pull back and start consuming less. They have already attained a saturation plateau on HDI.

The bottom-line is, the world is very much addicted to fossil fuels. In spite of various efforts to wean ourselves away, “by 2015 fossil fuels still accounted for 86% of all the world’s primary energy, just 4% less than a generation ago, in 1990”.

Then how do we address the problem of global warming and carbon emissions if we cannot have a fossil-free future? In the book Natural Gas: Fuel for the 21st Century (2015), Smil posits that there will be a gradual transition to natural gas as fossil fuel of choice. Coal generates 30 kg C/GJ, liquid hydrocarbons about 20 kg C/GJ and natural gas less than 15 kg C/GJ. Thus a large scale transition to natural gas would lead to reduced carbon emissions (not zero carbon emissions).

The carbon dioxide concentration in the atmosphere has touched 400 ppm. By 2050, no matter what steps we take, this will cross 450 ppm levels. Experts say that at this level, there will be about a 2 degree change in global average temperatures that will lead to large scale effects. Global warming turns out to be a pressing (and wicked) problem with no easy solutions.

Chennai Metro: Three Electric Autos Flagged Off At Alandur Station To Meet Last-Mile Connectivity Requirements

0

In association with Namma Auto Project, Chennai Metro Rail Limited (CMRL) has flagged off e-autos that function as a feeder service from the metro station at Alandur on a pilot basis.

CMRL had promised to reduce carbon emission and introduce a green public transport network. Three electric autos, which charge commuters ten rupees from the Alandur metro station to DLF IT Park and Porur, has set the example now.

Officials said the autos are free of any noise and come with an additional feature of zero tail pipe emission and is any day a cleaner, greener form of transport than anything else.

Times of India quoted Narasim Prasad, Director (Systems and Operations), CMRL as saying, “We are running feeder services from various metro stations, but the launch of an electric feeder system is an extension of CMRL’s mandate to offer our customers an effective means of transport for a sustainable future.”

Namma Auto’s Manju Menon added, “This project also provides backing to our focus on implementing the sustainable development goals which include building a sustainable community and promotes action to improve climate change,” Times of India reported.

Namma Metro Employees Stage Night Protest At Baiyappanahalli Station; Day’s Services Uncertain Till Last Minute

0

After disagreements between the management and employees of Namma Metro in Bengaluru, about 300 employees took to protest in the early hours of the morning at Baiyappanahalli depot on Friday (11 January).

Gathering there around 1:30 am, the employees raised slogans against the management, demanded revision of salary and put forth their demand that the union must be recognised. This put the day’s metro services in jeopardy until the last minute.

Ajay Seth, Managing Director of Bangalore Metro Rail Corporation Limited (BMRCL), met the employees and told them that their demands would be met within a month’s time. This diffused tensions a bit. He took questions for about 90 minutes and addressed every question that came his way.

Times of India has reported that the vice-president of Bangalore Metro Rail Employees Union, Suryanarayana Murthy, said the protests will intensify should the demands not be met.

About two years ago, members of the union had halted Metro services for seven hours after an employee was allegedly mistreated by the police.

Kolkata: Why The Recent Building Collapses Will Not Be The Last In The City

  • Geologists say that thousands of aquifers exist under Kolkata’s surface and disasters like the one at Bowbazar are just waiting to happen.

    And that’s because hundreds of waterbodies — ponds, lakes, canals and creeks — were filled up to construct buildings in the city and the suburbs.

The recent collapse of a number of buildings in central Kolkata due to tunnelling work for the East-West Metro Rail project should be a wake-up call for the city.

That’s because lakhs of buildings dotting vast swathes of the city and its suburbs stand on very unstable ground and could face the same fate as the ones which are now a heap of rubble.

The buildings in central Kolkata collapsed after the tunnel-boring machine hit an underground aquifer that no one knew existed. Water drained out from the punctured aquifer, leading to massive subsidence and the consequent building collapses.

But it is not in Bowbazar — the affected area — alone where such an unknown aquifer existed. Geologists say that thousands of such aquifers exist under Kolkata’s surface and disasters like the one at Bowbazar are just waiting to happen.

And that’s because hundreds of waterbodies — ponds, lakes, canals and creeks — were filled up to construct buildings in the city and the suburbs.

“When a waterbody is filled up, the water just does not simply disappear. Small and large aquifers and underground water pockets are formed when a waterbody is filled up.

“These aquifers and water pockets are dynamic at times and even a mild tremor can trigger them to merge or splinter. That poses a great danger to buildings and structures above them,” said Rathin Chandra Banerjee, a geologist.

Banerjee points out the case of the building collapses at Bowbazar. “Old maps of Kolkata show there were five big ponds at exactly the same spot at which the buildings collapsed or suffered severe damages. There was also a creek nearby,” he said.

Banerjee says the old maps show that what is present-day Kolkata was once a network of canals and small rivers, and dotted with numerous waterbodies. All these were filled up to construct buildings.

“These waterbodies were repositories of excess rainwater and groundwater. They may have been filled up, but we know little of how nature, through its own dynamics, has created underground aquifers that make the buildings above or near them very unstable,” says Banerjee.

Geologists say the Bowbazar disaster ought to serve as a wake-up call for Kolkatans and the authorities. They recommend going back to old maps of Kolkata to locate the various waterbodies that existed in the past.

“An extensive underground mapping with the help of remote sensing and other modern gadgets should be undertaken to locate all underground aquifers.

“Once they have been mapped, areas that are considered dangerous should be demarcated and, in consultation with experts from various fields, remedial measures should be undertaken,” said Vimal Singh, another geologist.

The remedial measures should include evacuation from very dangerous zones where mild tremors can cause subsidence and building collapses. These buildings should be demolished and areas that had a concentration of waterbodies should be restored to their original nature.

“It would be advisable to re-excavate some portions of such areas to pave way for restoration of at least some of the waterbodies and take the pressure off the aquifers,” said Singh.

That, though, is easier said than done. “Given the pressure on land in densely-populated Kolkata, it will be impossible to demolish buildings in very unsafe zones and undertake mitigation measures.

“As it is, we face immense problems with evacuating people from very unsafe buildings that are on the verge of collapse. To do so from buildings that are overtly safe and then demolish them would be impossible,” said a senior engineer of the Kolkata Municipal Corporation.

Thus, Kolkata and its suburbs may witness more Bowbazar-like disasters and there is little that can be done to prevent them. But for the future, one strict rule that ought to be laid down is that no more waterbodies should be filled up.

NCLAT Proposes Oversight By A Supreme Court Judge For IL&FS Asset Sale

National Company Law Appellate Tribunal (NCLAT), an appellate tribunal, proposed on Friday (11 January) that a retired Supreme Court (SC) judge should oversee the sale of assets by the financially-stressed Infrastructure Leasing and Financial Services Ltd (IL&FS), reports Mint.

The appellate tribunal will suggest to the government and IL&FS to get the matter supervised by a retired Supreme Court judge,” remarked a two-judge bench. “IL&FS will provide details of all arbitral proceeding against it and its 348 subsidiaries,” the bench added.

It was reported on 2 January (2019) that the debt-laden non-banking financial company (NBFC) major, IL&FS, had invited bids to sell its real estate assets to raise funds and trim its massive debt.

The company is also looking for buyers for its road assets constructed under the engineering, procurement and construction (EPC) model. Its operation and maintenance (O&M) businesses are on sale too.

However, it clarified yesterday (11 January) that it would neither indemnify nor provide warranties to potential buyers willing to buy its assets.

September crisis

IL&FS, one of India’s top NBFCs that lent heavily to big infrastructure projects, defaulted on its loan repayments in September 2018. This default triggered a market-wide liquidity crisis in the Indian financial system. The company has an accumulated debt of Rs 91,000 crore.

Following the takeover, the government moved swiftly and replaced the company’s board with its nominees, including Uday Kotak, the government’s banking crisis manager.
