  • Super Cyclone Amphan and its threats

    The storm system in the Bay of Bengal, Amphan, developed into a super cyclone and is expected to make landfall along the West Bengal-Bangladesh coast very soon.

    Realted PYQ:

    Q. In the South Atlantic and South Eastern Pacific regions in tropical latitudes, cyclone does not originate. What is the reason? (CSP 2015)

    (a) Sea Surface temperature are low
    (b) Inter Tropical Convergence Zone seldom occurs
    (c) Coriolis force is too weak
    (d) Absence of land in those regions

    Super Cyclone Amphan

    • Cyclone Amphan is a tropical cyclone formed over the Bay of Bengal that has intensified and likely to turn into a “super cyclonic storm (maximum wind speed is 224 kmph)”.
    • It has been named by Thailand.
    • Amphan is the equivalent of a Category 5 hurricane on the Saffir-Simpson Hurricane Wind Scale.
    • By the time it makes landfall in West Bengal, Amphan is expected to tone down into a category 4 Extremely Severe Cyclonic (ESC) storm with a wind speed of 165-175 kmph and gusting to 195 kmph.

    What makes it a nightmare?

    • This is the first super cyclone to form in the Bay of Bengal after the 1999 super cyclone that hit Odisha and claimed more than 10,000 lives.
    • It is the third super cyclone to occur in the North Indian Ocean region after 1999 which comprises of the Bay of Bengal, the Arabian Sea and the northern part of the Indian Ocean.
    • The other two super cyclones were Cyclone Kyarr in 2019 and Cyclone Gonu in 2007.

    Recent cyclones in the region

    • From 1965 to 2017, the Bay of Bengal and the Arabian Sea collectively registered 46 ‘severe cyclonic storms’.
    • More than half of them occurred between October and December.
    • Seven of them occurred in May and only two (in 1966 and 1976) were recorded in April, according to data from the IMDs cyclone statistics unit.
    • Cyclone Phailin in 2013 and the super cyclone of 1999 — both of which hit coastal Odisha — have been the most powerful cyclones in the Bay of Bengal in the past two decades in terms of wind speed.
    • Last year, Fani, which was an ESC made landfall in Odisha and ravaged the State, claiming at least 40 lives.

    Back2Basics: Tropical Cyclones

    • Cyclones are formed over slightly warm ocean waters.
    • The temperature of the top layer of the sea, up to a depth of about 60 metres, need to be at least 28°C to support the formation of a cyclone.
    • This explains why the April-May and October-December periods are conducive for cyclones.
    • Then, the low level of air above the waters needs to have an ‘anticlockwise’ rotation (in the northern hemisphere; clockwise in the southern hemisphere).
    • During these periods, there is an ITCZ in the Bay of Bengal whose southern boundary experiences winds from west to east, while the northern boundary has winds flowing east to west.
    • This induces the anticlockwise rotation of the air.
    • Once formed, cyclones in this area usually move northwest. As it travels over the sea, the cyclone gathers more moist air from the warm sea and adds to its heft.

    What strengthens them?

    • A thumb rule for cyclones is that the more time they spend over the seas, the stronger they become.
    • Hurricanes around the US, which originate in the vast open Pacific Ocean, are usually much stronger than the tropical cyclones in the Bay of Bengal, a relatively narrow and enclosed region.
    • The cyclones originating here, after hitting the landmass, decay rapidly due to friction and absence of moisture.

    Grading of Cyclones

    • Tropical cyclones in the Bay of Bengal are graded according to maximum wind speeds at their centre.
    • At the lower end are depressions that generate wind speeds of 30 to 60 km per hour, followed by:
    1. cyclonic storms (61 to 88 kmph)
    2. severe cyclonic storms (89 to 117 kmph)
    3. very severe cyclonic storms (118 to 166 kmph)
    4. extremely severe cyclonic storms (167 to 221 kmph) and
    5. super cyclones (222 kmph or higher)

  • Risk of Early Locusts Attacks: A new concern

    Locusts normally arrive during July-October but have already been spotted in Rajasthan. At a time India is battling COVID, they present a new worry with their potential for exponential growth and crop destruction.

    Along with being a disaster issue, Locust attack is also a challenge for India’s food security. Discuss what socio – economic and technological ways can be adopted to tackle this menance.

    What exactly are Locusts?

    • The desert locust (Schistocerca gregaria) is a short-horned grasshopper that is innocuous while it is in a “solitary phase” and moving about independently.
    • These winged insects differ from normal hoppers and become dangerous only when their populations build up rapidly and the close physical contact in crowded conditions triggers behavioural changes.
    • They, then, enter the “gregarious phase”, by grouping into bands and forming swarms that can travel great distances (up to 150 km daily), while eating up every bit of vegetation on the way.
    • If not controlled at the right time, these insect swarms can threaten the food security of countries.

    How seriously should the first sightings be viewed?

    • The damage potential of locusts has been limited in India only because of the country hosting a single breeding season — unlike Pakistan, Iran and East Africa, where they also multiply during January-June.
    • There’s nothing much to worry right now, as the rabi crop has already been harvested and farmers are yet to commence plantings for the new Kharif season.
    • The locusts’ bands so observed are less populated. But their timing, though, is cause for concern.
    • The normal breeding season for locusts in India is July-October. But this time, they have been sighted by mid-April.
    • Last year, too, they were seen towards end-May as isolated grasshoppers.
    • The longer time to breed is more conducive for a build-up of gregarious insect swarms, as opposed to solitary, innocuous hoppers.

    Control measures in India

    • India has a Locust Control and Research scheme that is being implemented through the Locust Warning Organisation (LWO), established in 1939.
    • It was amalgamated in 1946 with the Directorate of Plant Protection Quarantine and Storage (PPQS) of the Ministry of Agriculture.
    • The LWO’s responsibility is monitoring and control of the locust situation in Scheduled Desert Areas mainly in Rajasthan and Gujarat, and partly in Punjab and Haryana.
    • The LWO publishes a fortnightly bulletin on the locust situation.

    What kind of damage can they cause?

    • Locusts are polyphagous, i.e. they can feed on a wide variety of crops.
    • Secondly, they have the ability to multiply rapidly. A single female desert locust lays 60-80 eggs thrice during its roughly 90-day life cycle.
    • It is estimated that a 1-square-km area can accommodate 40-80 million of these insects, making the growth of their swarms exponential quite like the Covid-19 virus.

    What is the genesis of the present locust upsurge, particularly in East Africa?

    • It lies in the Mekunu and Luban cyclonic storms of May and October 2018 that struck Oman and Yemen, respectively.
    • These turned large desert areas in remote parts of the southern Arabian Peninsula into lakes, which allowed the insects to breed undetected across multiple generations.
    • The swarms attacking crops in East Africa reached peak populations from November onwards while building up since the start of this year in southern Iran and Pakistan.
    • Widespread rains in East Africa in late March and April have enabled further breeding.
    • Prior to that, the locusts from spring breeding areas of southwest Pakistan and southern Iran would arrive in Rajasthan and Gujarat during May-June.
    • They would, then, breed with the onset of the southwest monsoon rains and continue doing so through the Kharif cropping season.

    What can and should be done?

    • If the monsoon is good, and in the absence of control operations, the magnitude of attack could be worse than in the 2019-20 rabi season.
    • The last year’s locust incursions were the first and most significant since 1993.
    • Local authorities in Rajasthan and Gujarat had to treat over 4.30 lakh hectares of infested areas with sprayers mounted on tractors and other vehicles.

    Pesticides give better control

    • The old generation organophosphate insecticides such as Malathion (96% ultra-low volume aerial application) are effective against locusts.
    • About one litre of the chemical is necessary to treat a hectare of their breeding areas, including trees where they halt for the night.
    • There is ample stock of pesticides to control any swarms in India.

    Locust Invasions and its mitigation

  • Vizag Gas Leak: What is Styrene Gas?

    A gas leak has claimed at least 11 lives and affected thousands of residents in five villages in Visakhapatnam in Andhra Pradesh.  The source of the leak was a styrene plant owned by South Korean electronics giant LG.

    Practice question:

    Despite a robust policy framework governing the hazardous chemicals in India, the recent gas leakage incident in Vizag highlights India’s unaddressed vulnerability to chemical disasters. Criticallly comment.

    Vizag gas lead: What is styrene?

    • It is a flammable liquid that is used in the manufacturing of polystyrene plastics, fibreglass, rubber, and latex.
    • Styrene is also found in vehicle exhaust, cigarette smoke, and in natural foods like fruits and vegetables.
    • According to The Manufacture, Storage and Import of Hazardous Chemicals Rules, 1989, styrene is classified as a toxic and hazardous chemical.

    What happens when exposed to styrene?

    • A short-term exposure to the substance can result in respiratory problems, irritation in the eyes, irritation in the mucous membrane, and gastrointestinal issues.
    • And long-term exposure could drastically affect the central nervous system and lead to other related problems like peripheral neuropathy.
    • It is, likely, a carcinogenic substance that can react with oxygen in the air to mutate into styrene dioxide, a substance that is more lethal.
    • However, there is no sufficient evidence despite several epidemiology studies indicating there may be an association between styrene exposure and an increased risk of leukaemia and lymphoma.

    What are the symptoms?

    • Symptoms include headache, hearing loss, fatigue, weakness, difficulty in concentrating etc.
    • Animal studies have reported effects on the nervous system, liver, kidney, and eye and nasal irritation from inhalation exposure to styrene.

    How bad is the situation in Visakhapatnam?

    • It is yet unclear whether the deaths are due to direct exposure to styrene gas or one of its byproducts.
    • However, hundreds of people including many children were admitted to hospitals.
    • The cases are high as the gas leak was only detected at 3 am in the morning, meaning several crucial hours have been lost till safety precautions were taken.
    • More fatally, the gas was leaked while people were fast asleep.

    What caused the leak?

    • Styrene monomer was used at the manufacturing plant to produce expandable plastics.
    • The storage requirement of styrene monomer strictly mentions that it has to be below 17 degrees Celsius.
    • There was a temporary and partial shutdown of the plant because of the nationwide lockdown.
    • The leak occurred as a result of styrene gas not being kept at the appropriate temperature.
    • This caused a pressure build-up in the storage chamber that contained styrene and caused the valve to break, resulting in the gas leakage.

    Is it under control?

    • The leak has been plugged and NDRF teams moved into the five affected villages and have started opening the houses to find out if anyone was stranded inside.
    • The Covid-19 preparedness helped a lot as dozens of ambulances with oxygen cylinders and ventilators were readily available.
    • The spread of the gas depends on wind speeds. So far it is estimated that areas within a five-kilometre radius have been affected.

    What are the guidelines on the storage of hazardous chemicals in plants?

    After the Bhopal disaster, much legislation was enacted starting from the Environment (Protection) Act, 1986 to the Public Liability Insurance Act, 1991. They are-

    Environment (Protection) Act, 1986 Omnibus act, which gives sweeping powers to Central government to take all measures to protect the environment
    Environment (Protection) Rules, 1986 Set discharge and product standards – source standards for restricting pollution; product standards for manufactured goods and ambient air and water standards – for regulating quality of life and environmental protection
    Hazardous Waste (Management Handling and Transboundary Movement) Rules, 1989 Industry required to identify major accident hazards, take preventive measures and submit a report to the designated authorities
    Manufacture, Storage And Import Of Hazardous Chemicals Rules, 1989 Importer must furnish complete product safety information to the competent authority and must transport imported chemicals in accordance with the amended rules.
    Chemical Accidents (Emergency, Planning, Preparedness and Response) Rules, 1996 Centre is required to constitute a central crisis group for management of chemical accidents; set up quick response mechanism termed as the crisis alert system. Each state is required to set up a crisis group and report on its work.
    Factories Amendment Act, 1987 Provision to regulate siting of hazardous units; safety of workers and nearby residents and mandates for on-site emergency plans and disaster control measures
    Public Liability Insurance Act, 1991 Imposes a no-fault liability on the owner of hazardous substance and requires the owner to compensate victims of accident irrespective of any neglect or default. For this, the owner is required to take out an insurance policy covering potential liability from any accident.

     

  • ‘Lost at Home’ Report by UNICEF

    More than five million people were internally displaced in India due to natural disasters, conflict and violence in 2019, constituting the highest number of new internal displacements in the world.

    Try to answer:

    ‘Environmental migrant’ is an issue that globally countries should start taking seriously. Discuss the statement with respect to India which already ranks high in climate vulnerability.

    The ‘Lost at Home’ Report

    • The report is published by the UN Children’s Fund (UNICEF).
    • It says that almost 33 million new displacements were recorded in 2019 — around 25 million were due to natural disasters and 8.5 million as a consequence of conflict and violence.
    • Of these, there were 12 million new displacements involving children, including around 3.8 million of them caused by conflict and violence, and 8.2 million due to disasters linked mostly to weather-related events.
    • The report said that natural disasters resulted in more new displacements than conflict and violence.
    • Almost 10 million new displacements in 2019 were recorded in East Asia and the Pacific (39 %) — and almost the same number in South Asia (9.5 million).
    • The report looks at the risks internally displaced children face —child labour, child marriage, trafficking among them — and the actions urgently needed to protect them.

    Displacement in India

    • India, the Philippines, Bangladesh and China all suffered from natural disasters leading to displacement in the millions, which accounted for 69% of global disaster-induced displacements.
    • These were overwhelmingly caused by extreme conditions created by dangerous storms and floods.
    • In India, the total number of new internal displacements in 2019 stood at 5,037,000 – including 5,018,000 due to natural disasters and 19,000 because of conflict and violence.

    Global Scenario

    • India is followed by the Philippines, Bangladesh and China.
    • The Philippines accounted for 4.27 million new internal displacements due to natural disasters, conflict and violence, Bangladesh 4.08 million and China 4.03 million.
    • The largest number of internally displaced children due to conflict is found in the Middle East and North Africa (MENA) and sub-Saharan Africa.
    • Internally displaced persons are concentrated in two regions — the Middle East and North Africa and West and Central Africa.
    • The MENA region recorded over 12 million IDPs as a result of conflict and violence at the end of 2019. Almost all of them lived in just three countries — Syria, Yemen, and Iraq — and around 5 million were children.

    What makes the situation worse?

    • The COVID-19 pandemic is only making a critical situation worse.
    • Camps or informal settlements are often overcrowded and lack adequate hygiene and health services.
    • Physical distancing is often not possible, creating conditions that are highly conducive to the spread of the disease, the report said.

  • Armed Forces: their role during crisis, procedures for requisition

    As the Army moves in to take over the COVID-19 quarantine facility in Delhi, the procedure for calling the armed forces to help the civil administration is in the spotlight.

    Requisition the Army

    • The regulations permit civil authorities to requisition the Army for controlling law and order, maintaining essential services, assisting during natural calamities such as earthquakes, and any other type of help that may be needed by the civil authorities.
    • The procedure for requisitioning armed forces is governed under several guidelines including:
    1. ‘Aid to Civil Authorities’ under the guidelines laid in Instructions on Aid to the Civil Authorities by the Armed Forces, 1970;
    2. Regulations for the Army, Chapter VII, Paragraphs 301 to 327 and
    3. Manual of Indian Military Law, Chapter VII

    How is Army invited?

    • Civil administration requests the Local Military Authority for assistance, for the maintenance of law and order, maintenance of essential services, disaster relief and other types of assistance.
    • Armed forces can be asked to provide troops and equipment for a flag march, rescue and relief, evacuation, and immediate aid.
    • The current case of checking the spread of COVID-19 is different, as the medical aspect is predominant.
    • These resources are being controlled centrally and judiciously, because of the requirement of doctors, equipment and facilities.

    Why need Armed forces in such situations?

    • Besides the specialised medical resources, which are centrally controlled, the local units are prepared for maintenance of law and order, crowd control, curfew in sensitive areas etc.
    • Moreover provision of essential supply of electricity and water, restoration of essential services, emergency feeding and shelter, prevention of panic, prevention of theft and loot are other areas of concerns.
    • During such multi-faceted challenges, local authorities have shortfall to perform all such functions.

    In such situations, what happens to the armed forces’ primary role?

    • Providing aid to civil authorities, as and when called upon to do so, is a secondary task for the armed forces.
    • It cannot replace the primary role of ensuring external security and operational preparedness.

    Is there a ceiling on such deployment?

    • No, there is no such ceiling either of a duration of deployment or on the number of armed forces personnel that can be deployed to aid civil authority.
    • The National Crisis Management Committee (NCMC), headed by the cabinet secretary, is the final authority.

    Are there any templates or instances from the past that are applicable here?

    • The current situation is different from earlier cases such as tsunami or super-cyclone, which were natural disasters.
    • The major difference is that specialists are the key in the current situation, and their tasks cannot be performed by general duty soldiers.

    Who pays for the costs incurred?

    • The civil administration is responsible for the costs incurred by the armed forces in these roles.
    • The cost of assistance provided by the Armed Forces is recovered in accordance with the instructions contained in ‘Instructions on Aid to Civil Authorities by the Armed Forces 1970’.

    What is the role of the National Disaster Management Authority?

    • NDMA is involved in secondary follow-ups by the Home Ministry and is not very actively involved in the current case.
    • The roles of the Ministries of Health, Home, Civil Aviation and Defence are predominant in this case.
    • The armed forces are aligned with them at the apex level viz NCMC.
    • The directions are followed by execution-level coordination which is done by respective secretaries in the government.

  • Prime Minister’s National Relief Fund (PMNRF)

    Keeping in view the novel coronavirus crisis across the country, various govt. employees, celebrities and political dignitaries are open-heartedly contributing to the PM’s National Relief Fund (PMNRF) to help combat the disease.

    PM’s National Relief Fund (PMNRF)

    • In pursuance of an appeal by the then PM, Pt. Nehru in January, 1948, the Prime Minister’s National Relief Fund (PMNRF) was established with public contributions.
    • It was aimed to assist displaced persons from Pakistan.
    • The resources of the PMNRF are now utilized primarily to render immediate relief to families of those killed in natural calamities like floods, cyclones and earthquakes, etc. and to the victims of the major accidents and riots.
    • Assistance from PMNRF is also rendered, to partially defray the expenses for medical treatment like heart surgeries, kidney transplantation, cancer treatment and acid attack etc.
    • The fund consists entirely of public contributions and does not get any budgetary support.

    Legal status

    • PMNRF has not been constituted by the Parliament.
    • The fund is recognized as a Trust under the Income Tax Act and the same is managed by PM or multiple delegates for national causes.

    Donations

    • PMNRF accepts only voluntary donations by individuals and institutions.
    • Contributions flowing out of budgetary sources of Government or from the balance sheets of the public sector undertakings are not accepted.
    • Conditional contributions, where the donor specifically mentions that the amount is meant for a particular purpose, are not accepted in the Fund.

    Its operation

    • PMNRF operates from the Prime Minister’s Office and does not pay any license fee.
    • PM is the Chairman of PMNRF and is assisted by Officers/ Staff on an honorary basis. Permanent Account Number of PMNRF is AACTP4637Q.

    Tax exemptions

    • PMNRF is exempt under the Income Tax Act, 1961 under Section 10 and 139 for return purposes.
    • Contributions towards PMNRF are notified for 100% deduction from taxable income under section 80(G) of the Income Tax Act, 1961.

  • Explained: Notified Disaster

    The Ministry of Home Affairs has decided to treat COVID-19 as a notified disaster for the purpose of providing assistance under the State Disaster Response Fund (SDRF).

    What is a Disaster?

    According to the Disaster Management Act, 2005 a disaster is defined as-

    • A catastrophe, mishap, calamity or grave occurrence in any area, arising from natural or manmade causes, or by accident or negligence which results in substantial loss of life or human suffering or damage to, and destruction of, property, or damage to, or degradation of, environment, and is of such a nature or magnitude as to be beyond the coping capacity of the community of the affected area.
    • The MHA has defined a disaster as an “extreme disruption of the functioning of a society that causes widespread human, material, or environmental losses that exceed the ability of the affected society to cope with its own resources.

    What is the State Disaster Response Fund?

    • The SDRF is constituted under the Disaster Management Act, 2005 and is the primary fund available with state governments for responses to notified disasters.
    • The Central government contributes 75 per cent towards the SDRF allocation for general category states and UTs, and over 90 per cent for special category states/UTs (which includes northeastern states, Sikkim, Himachal Pradesh and Uttarakhand).
    • For SDRF, the Centre releases funds in two equal instalments as per the recommendation of the Finance Commission.
    • The disasters covered under the SDRF include cyclones, droughts, tsunamis, hailstorms, landslides, avalanches and pest attacks among others.

    The NDRF

    The National Disaster Response Fund, which is also constituted under the Disaster Management Act, 2005 supplements the SDRF of a state, in case of a disaster of severe nature, provided adequate funds are not available in the SDRF.

    Categories of disaster

    • A High Power Committee on Disaster Management was constituted in 1999 to identify disaster categories.
    • It identified 31 disaster categories organised into five major subgroups, which are: water and climate-related disasters, geological related disasters, chemical, industrial and nuclear-related disasters and biological related disasters, which includes biological disasters and epidemics.

    Have there been such instances in the past?

    • In 2018, in view of the devastation caused by the Kerala floods, political leaders in Kerala demanded that the floods be declared a “national calamity”.
    • As of now, there is no executive or legal provision to declare a national calamity.
    • In 2001, the National Committee on Disaster Management under then PM was mandated to look into the parameters that should define a national calamity.
    • However, the committee did not suggest any fixed criterion.
    • In the past, there have been demands from states to declare certain events as natural disasters, such as the Uttarakhand flood in 2013, Cyclone Hudhud in Andhra Pradesh in 2014, and the Assam floods of 2015.
