Mumbai once again struggled to stay afloat after the first heavy spell of rain this year, bringing back memories of the July 2005 flood. Each massive rainfall event is making it evident that the city is putting on a brave front and projecting resilience, but the failure of the Maharashtra government to upgrade its tattered infrastructure is taking a heavy toll and weighing down on the financial capital.
Impact of monsoon
A single day of rain has killed 22 people in a wall collapse in north Mumbai, while many more died in Pune and elsewhere.
In Ratnagiri, a dam gave way creating a catastrophe; flights have been cancelled and normal life is affected.
Clearly, the State government should have regarded the 94 cm of rain that paralysed Mumbai in one day 14 years ago as the baseline disaster to prepare for.
That it could not manage 37 cm in 24 hours, that too after incurring a massive expenditure on management projects, shows a lack of resolve among political leaders, rampant inefficiency and lack of integrity in the administrative machinery.
As one of the wettest metropolises in India getting about 210 cm of rain annually, it should have been a top order priority to restore rivers and canals to manage floods.
The government s needs to explain why Mumbai is yet unprepared to cope, especially when rainfall is projected to become erratic in coming years, and when scientific insights point to intense rainfall in a short span of time, driven by warmer oceans and hotter cities.
CAG’s Report on ineffectiveness
In a recent report, the Comptroller and Auditor General identified prolonged delays in the upgrading of storm water drain infrastructure in Mumbai.
On the other hand, after the deluge of 2005, the consensus was for the flood-carrying capacity of the Mithi river in the city to be increased.
But the choked and polluted river was again overflowing this year.
Change in monsoon rainfall pattern
Beyond the sclerotic management of flood waters that relies on storm drains in Mumbai, and several other Indian cities, there is a need for a new urban paradigm.
For one thing, Mumbai, Thane, Ratnagiri and Raigad have, during the last century, displayed a high seasonality index, indicating a relatively small monsoon window bringing a lot of rain.
This is in contrast to steady, prolonged rain in the central districts in Maharashtra.
So a new climate change-influenced normal could mean fewer days of torrential rain and erratic monsoons.
Managing them calls for a new approach that is ecological, and makes restoration of existing urban wetlands and creation of reservoirs and water channels a high priority.
The water question is the biggest challenge for Indian cities today, as both drought and flood are common.
State governments should give it priority and address it by making urban planning people-centric. A strong framework is needed to manage water, starting with Mumbai.
Mains Paper 3: Environment| Disaster and Disaster Management
From UPSC perspective, the following things are important:
Prelims level: FBMAP
Mains level: Flood management
The Union Cabinet has approved the “Flood Management and Border Areas Programme (FMBAP)” for Flood Management Works in entire country and River Management Activities and works related to Border Areas.
The Scheme “FMBAP” has been framed by merging the components of two continuing XII Plan schemes titled “Flood Management Programme (FMP)” and “River Management Activities and Works related to Border Areas (RMBA)”.
The aim of the scheme is to assist the State Governments to provide reasonable degree of protection against floods in critical areas.
The works under the scheme will protect valuable land from erosion and flooding and help in maintaining peace along the border.
The Scheme aims at completion of the on-going projects already approved under FMP.
Further, the scheme also caters to Hydro-meteorological observations and Flood Forecasting on common rivers with the neighbouring countries.
The funding pattern for FM Component for works in general category States will continue to be 50% (Centre): 50% (State).
For projects of North Eastern States, Sikkim, J&K, Himachal Pradesh and Uttarakhand, the funding pattern will continue to be 70% (Centre): 30% (State).
RMBA component being specific to activities in border areas, the project works will continue to be funded as 100% grant-in-aid / central assistance.
The FMBAP Scheme will be implemented throughout the country for effective flood management, erosion control and anti-sea erosion.
The proposal will benefit towns, villages, industrial establishments, communication links, agricultural fields, infrastructure etc. from floods and erosion in the country.
The catchment area treatment works will help in reduction of sediment load into rivers.
Mains Paper 2: Polity| Functions and responsibilities of the Union and the States, issues and challenges pertaining to the federal structure, devolution of powers and finances up to local levels and challenges therein.
From UPSC perspective, the following things are important:
Prelims level: Basic knowledge of the federal structure of India.
Mains level: The news-card analyses the federal fallout of the Kerala flood relief funding row, in a brief manner.
The differences between the Kerala and Central governments over the denial of external assistance to rebuild the State after the devastating floods of August last year surfaced again last month.
The Kerala Governor Justice in his policy speech in the Assembly had said that the Kerala government had requested the Centre to enhance its borrowing limit to mobilise additional resources for rebuilding the flood-hit State.
The state government is still awaiting a favourable response from the Central government in this regard.
Further, a Kerala Minister who represented Kerala at the Pravasi Bharatiya Divas in Varanasi, complained that he was not allowed to raise the issue there.
The bitterness over the flood money still persists.
Competitive federalism: a double-edged sword
Competitive federalism, in the context of interaction with foreign countries as promoted by the Prime Minister, has proved to be a double-edged sword.
Kerala Chief Minister now stands accused of violating rules regarding the seeking of foreign assistance.
He remains unclear on how to make up for the shortfall, of several crores.
The Central government is unable to provide the funds while Kerala has been stopped in its tracks from seeking resources from abroad, either from the Kerala diaspora or from friendly foreign governments.
Misunderstandings on both sides
The present situation is a result of a series of errors of judgment and misunderstandings on both sides.
Mutual political suspicion and a lack of appreciation of the complexities of the international situation have brought about a confrontation.
The Chief Minister may have even made diplomatic and tactical mis-judgements.
India had no qualms about receiving foreign assistance for disaster management till 2004.
But when India’s aspiration for permanent membership of the UN Security Council met with strong resistance, New Delhi hit upon the idea of forcing a vote in the General Assembly.
The plan was to secure a two-thirds majority and then attempt to embarrass the permanent members into supporting the expansion of the Security Council.
The two false presumptions were that India would win the required number of votes and that the Security Council would wilt under pressure from the General Assembly.
In fact, many Assembly members were opposed to the veto even for the existing permanent members and had no interest in creating more permanent members with veto.
India thought that it could win over the other countries if it was seen to be helping them in emergencies rather than seeking such assistance for itself.
Rules were laid regarding foreign assistance to bring some clarity
The tsunami of 2004 and the threat of piracy in the Indian Ocean provided India an opportunity to test its new posture.
Everybody was grateful, but it made no difference to India’s claim to permanent membership.
However, the present government decided to lay down the rules regarding foreign assistance in order to bring some clarity to the situation.
The rules which were framed in 2016 clarified that India would not solicit any assistance but would receive relief assistance, even as cash, from individuals, charitable institutions and foundations.
If cash were to be offered bilaterally by foreign governments, the matter would be considered on a case-by-case basis.
The UAE’s offer
The Prime Minister was informed by the United Arab Emirates (UAE) authorities that relief assistance was being put together as a special gesture and the Prime Minister reciprocated with a warm reply of gratitude.
However, the Kerala Chief Minister’s announced that the UAE would provide ₹700 crore, made on the same day as the Central government’s announcement of a provision of ₹500 crore.
It appeared as the UAE was more generous than New Delhi was to Kerala and that the Central government was not empathetic to Kerala’s plight because of political considerations.
An embarrassed UAE government then asked its Ambassador in New Delhi to deny that there was any specific offer of ₹700 crore.
An immediate consequence was a reluctance by other governments to make any offer of bilateral assistance.
No one could answer the question whether any offer from other governments would be accepted.
When the Thai Ambassador in Delhi was stopped from being at a ceremony to hand over relief goods to an Indian official, the world was convinced that India would not accept resources.
The issue was also politicised.
Unwise decision by Kerala government
Against this backdrop, Kerala put forward an unwise proposal to despatch its Ministers abroad to collect donations.
This was unacceptable in the context of the policy that had crystallised after the floods in Kerala and the Central Government having refused permission for Ministers other than the Chief Minister to travel to countries.
Apart from the ignominy of soliciting donations, there was a clear likelihood of receiving very little by way of cash donations.
The possibility of loans from the International Monetary Fund and the World Bank became distant as the Centre refused to raise the limits on loans from these global organisations that a State government could take.
The emergence of the Sabarimala crisis further eroded the credibility of the State Government and much of the empathy over the flood damage was also lost.
Marshalling of resources is the responsibility of the Union government according to the Constitution.
The only option before Kerala is to demand more funding from the Centre to make up the shortfall.
The situation is a tragedy of errors caused by an inadequate familiarity with decision making and the complexity of international relations.
India is a federal state, but unitary in nature when it comes to national security and foreign policy.
Individual States may have some advantages in dealing with some countries in their neighbourhood, but they will do well not to transgress the thin line when it comes to managing international relations.
Mains Paper 3: Science & Technology | developments & their applications & effects in everyday life
From UPSC perspective, the following things are important:
Prelims level: Central Water Commission (CWC), India Meteorological Department, Artificial intelligence, machine learning, geospatial mapping,
Mains level: Flood management in India and need of better practices to ensure minimal loss of life and property
Better flood warning
Union Water Resources Ministry has teamed up with Google to generate flood warnings
If there are signs of an imminent flood, a Google Maps user will be able to see what regions are likely to see water logging first and if their neighborhood is under threat
Google will provide a visualization via Google Maps and people will be able to see water levels build up in a region
CWC and Google will share technical expertise in the fields of artificial intelligence, machine learning, geospatial mapping and analysis of hydrological observation data to improve flood prediction systems, provide location-targeted, actionable flood warnings
Google Earth Engine will be used to help visualize and improve flood management and initiate a cultural project to build online exhibitions on the ‘Rivers of India’
Present system of warning
Currently, the Central Water Commission (CWC) warns of floods based on the rising water levels in reservoirs and if these are nearing a dam’s ‘danger marks’
Last year, it began a trial programme to give 3-day flood forecasts
The India Meteorological Department now provides inputs to the CWC on whether heavy rainfall is likely and if this could translate into large amounts of rainwater overflowing from river banks or catchments
Chennai witnessed its worst rainfall in 100 years. Let’s take a look at what are the main causes, it’s impact and possible ways forward to achieve [long and short term targets]
What exactly happened that wrecked a havoc in Chennai?
The catastrophic flooding in Chennai is the result of the heaviest rain in several decades.
This forced authorities to release a massive 30,000 cusecs from the Chembarambakkam reservoir into the Adyar river over two days. Causing it to flood its banks and submerge neighbourhoods on both sides.
It did not help that the Adyar stream is not very deep or wide, and its banks have been heavily encroached upon over the years.
Similar flooding triggers were in action at Poondi and Puzhal reservoirs, and the Cooum river that winds its way through the city.
So, unusually heavy rain has exposed the city’s broken urban planning, revealed its stolen natural waterways, and exposed its tolerance of illegal construction.
3 important Geo-climatic factors for heavy rain in 100 years –
Upper Air divergence
High moisture content
How does a strong El-nino affect Chennai?
The summer (southwest) monsoon is adversely affected, while the northeast monsoon or the winter monsoon is favourably affected.
In mid-November, the sea surface temperature in the central tropical Pacific was 3 degrees Celsius warmer than normal, the largest positive deviation in recorded history.
To officially beat the 1997-98 El Niño as history’s worst, sea surface temperatures must stay at these levels for three months.
How does inefficient urban planning causes floods?
1.5 lakh Illegal construction
Chocking of water exits
Badly planned or unimplemented projects
But, what was wrong with the Urban planning?
Chennai is located in a relatively flat area, hence it depends on natural water bodies, canals and rivers to drain the heavy water runoff during rains.
Its drainage and stormwater network, which is absent in many places, is inadequate even to convey water during moderate rains.
As a result, the city has a high exceedance flow (excess water that cannot be drained through the drainage system).
It often inundates neighbourhoods, particularly those in the suburbs, which are built in low-lying areas and poor roads. This scenario was foreseeable.
Let’s get into some details of unplanned Urban Space
Today, Chennai has a host of expensive infrastructure aimed at ushering in a “Make in Chennai” boom, a brand-new (though leaky) airport built on the floodplains of the River Adyar.
A sprawling bus terminal in flood-prone Koyambedu, a Mass Rapid Transit System constructed almost wholly over the Buckingham Canal and the Pallikaranai marshlands.
An IT corridor and a Knowledge Corridor consisting of engineering colleges constructed on waterbodies, and automobile and telecom SEZs and gated residential areas built on important drainage courses and catchments.
So, fact remains that the mindless development of Chennai over the last 2 decades, the filling up of lowlands and choking of stormwater drains and other exits for water has played a major part in the escalation of the crisis.
Way forward : Lessons from International Practices
First task : To enhance Preventive measures
It can learn a lesson or two from cities in Japan, Malaysia and Europe.
Well-prepared cities have mapped flood zones.
By combining field surveys, historical records, satellite imagery and infrastructure assessment, they have identified vulnerable areas.
Such maps and data are shared with citizens, which help them understand the status of their neighbourhoods and decide where to move or buy new homes.
More importantly, this data is used to regulate development.
The United Nations Office for Disaster Risk Reduction has collated data spanning 3 decades, starting from the 1980s, for various places in Tamil Nadu including Chennai.
The city corporation can quickly build on it.
Second task : To enhance Mitigation
Kuala Lumpur and Tokyo have built extensive water discharge tunnels to divert and store floodwater. This reduces the volume of water that washes the city.
Tokyo has one of the largest underground tunnels, running to a length 6.5 km, and the tank can hold 6,70,000 cubic metre of diverted water, which is later pumped into safe watercourses using turbines.
Canals such as the Veerangal Odai, which connected Adambakkam lake with Pallikaranai marsh in the suburbs, have almost disappeared. Reclaiming these water bodies is critical.
The city should also explore, as many others have done, the possibility of designing highways to conduct runoff water.
All this would warrant a thorough review of its urban engineering.
Third task : To enhance Response measures
In the first week following the heavy rains, ground reports reveal that the government response was inadequate and uncoordinated.
The spirited effort of citizens propelled rescue efforts, without which the damages would have been more severe.
As cities increasingly face natural hazards and terrorist attacks, they are investing in setting operation centres for early warning and rescue work.
For example, Rio de Janeiro has spent $14 million and created a real-time monitoring centre of infrastructure and traffic flows.
The recent experience clearly shows the need for early warning and dissemination of reliable information about floods and rescue.
Improved governance and non-interference of political parties in relief measures are critical.
Can you ponder on any long or short term solutions or any way ahead?
