Naming of cyclones?
- Cyclones around the world are named by Regional Specialised Meteorological Centres and Tropical Cyclone Warning Centres. There are a total of six RSMCs and five TCWCs, including the India Meteorological Department.
- IMD has been mandated with the duty to name cyclones that develop over the North Indian ocean, including Arabian Sea and Bay of Bengal
- IMD names cyclones of north IO along with Thailand, Myanmar, Sri Lanka, maldives, Pakistan, Oman and Saudi arabia, Iran, Qatar, Yemen, UAE (added in 2018)
- African countries are not part of consultation grp even though they share north IO
- IMD released a list of cyclone names in April 2020 as suggested by the 13 countries. These include: Gati, Nivar, Burevi, Yaas, Arnab, Aag, Vyom, Azar
‘Desert Locusts’: How they form swarms?
- As individuals, or in small isolated groups, locusts are not very dangerous. But when they grow into large populations their behaviour changes, they transform from ‘solitary phase’ into ‘gregarious phase’, and start forming ‘swarms’. A single swarm can contain 40 to 80 million adults in one square km, and these can travel up to 150 km a day.
- Large-scale breeding happens only when conditions turn very favourable in their natural habitat, desert or semi-arid regions. Good rains can sometimes generate just enough green vegetation that is conducive to egg-laying as well as hopper development.
- If left uncontrolled, a single swarm can increase 20 times of its original population in the first generation itself, and then multiply exponentially in subsequent generations.
‘Desert Locusts’: What factors led to their sudden and early growth this year?
- These locusts usually breed in the dry areas around Horn of Africa. Other breeding grounds are the adjoining Asian regions in Yemen, Oman, southern Iran, and in Pakistan’s Balochistan and Khyber Pakhtunkhwa provinces.
- Many of these areas received unusually good rains in March and April, and that resulted in large-scale breeding and hopper development. These locusts started arriving in Rajasthan around the first fortnight of April, much ahead of the normal July-October normal.
- Cyclonic storms Mekunu and Luban had struck Oman and Yemen respectively that year. Heavy rains had transformed uninhabited desert tracts into large lake where the locust swarms breed.
- Apart from the search for food, their movement has been aided by westerly winds that were, this time, further strengthened by the low-pressure area created by Cyclone Amphan in the Bay of Bengal. Locusts are known to be passive flyers, and generally follow the wind. But they do not take off in very strong windy conditions.
Locust control in India: history?
In the nineteenth century, India experienced serious locust outbreaks 8 times like in 1812, 1821, 1869, 1896-97 etc.
Measures taken:
- The first of these measures was to systematically collect and record data regarding locust occurrences.
- The colonial system employed an interesting mix of local reliance and global cooperation in collecting data. It rested on the exchange of knowledge and techniques between various provinces of India as well as with other countries similarly ravaged by the pestilence.
- after the 1927-’29 outbreak that ravaged the central and western parts of India was the need felt for a centralised organisation to gather information about locusts and control them. This resulted in the formation of the Standing Locust Committee in 1929 and the Central Locust Bureau in 1930. This culminated in 1939 in the establishment of the present-day Locust Warning Organisation.
Locust control in India: methods used?
- Currently, the most commonly used control is insecticide. Sprayed from land or aerial vehicles, whole swarms can be targeted in relatively short periods of time.
- Experts have expressed disappointment over the fact that despite the known side-effects of aerial spraying of pesticides, governments’ locust control policies are focussed only on chemical spray.
- Swarms of locusts are being scared away by the district administration in Panna using police sirens.
- Farmers in Budhni and Nasrullaganj areas of Madhya Pradesh’s Sehore district have been beating utensils in a bid to drive away locusts.
- Few non-chemical measures to consider:
- Destroy the breeding grounds and locust larvae before they could fly.
- Use of oil-tarred screens to kill locusts (also known as Cyprus screen).
- Net system and the dhotar method. The net system involved holding a “capricious” bag and swinging it around fields, trapping young locusts in the process. The dhotar method involved using a blanket to trip locusts resting on bushes.
- Devise an insect-control technique that involved ploughing the fallow lands where locusts are resting: the escaping insects became an easy target for birds.
- Natural predators such as wasps, birds and reptiles may prove effective at keeping small swarms at bay.
Locust Warning Organisation?
- (LWO) is responsible to monitor and control the locust situation in Scheduled Desert Area (SDA) mainly in the States of Rajasthan and Gujarat while partly in the States of Punjab and Haryana.
- established in 1939 and amalgamated in 1946 with the Directorate of Plant Protection Quarantine and Storage (PPQS) of the Ministry of Agriculture.
- The main objective of LWO is protection of standing crops and other green vegetation from the ravages of Desert locust
Directorate of Plant Protection Quarantine & Storage (PPQS)?
established in the year 1946 on the recommendation of Woodhead Commission as an apex organization for advising the GoI and SGs onall matters related to plant protection
It is an attached Office of Ministry of Agriculture and Farmers Welfare.
T/F: Orders under Disaster Management Act 2005 were invoked fr the first time in the country since the legislation was drafted
T
relevance of Disaster Management Act 2005 in the present Pandemic?
- COVID-19 is the first pan India biological disaster being handled by the legal and constitutional institutions of the country.
- The current lockdown has been imposed under the Disaster Management Act, 2005 (DM Act).
- Under the Act, the States and district authorities can frame their own rules on the basis of broad guidelines issued by the Ministry.
- Entry 29, Concurrent List “Prevention of the extension from one State to another of infectious or contagious diseases or pests affecting men, animals or plants,” can also be used for specific law making.
- Central government has included the Covid-19 outbreak as “Notified Disaster” as a “critical medical condition or pandemic situation”.
disaster management Act 2005?
The legal basis of the DM Act, is Entry 23, Concurrent List of the Constitution “Social security and social insurance”.
Obj: to manage disasters, including preparation of mitigation strategies, capacity-building and more.
Act calls for the establishment of National Disaster Management Authority (NDMA), with the Prime Minister of India as chairperson.
Act enjoins the Central Government to Constitute a National Executive Committee (NEC) to assist the National Authority.
All State Governments are mandated to establish a State Disaster Management Authority (SDMA).
disaster management Act 2005: NDMA?
apex Body of Government of India, with a mandate to lay down policies for disaster management.
It is headed by the Prime Minister of India and can have up to nine other members, one of them designated as Vice Chairperson
Since 2014, there have been four other members.
Fns:
- Approve the National Disaster Plan and Lay down policies on disaster management
- Approve plans prepared by Ministries or Departments of the CG
- Lay down guidelines to be followed by State Authorities in drawing up State Plan
- Recommend provision of funds for the purpose of mitigation
- It works closely with the National Institute of Disaster Management for capacity building.
T/F: In the federal polity of India, the primary responsibility of Disaster management vests with the state government.
T
Disaster Management Act 2005: NEC?
- A National Executive Committee is constituted under Section 8 of DM Act, 2005 to assist the National Authority in the performance of its functions.
- Union Home secretary is its ex-officio chairperson.
- NEC has been given the responsibility to act as the coordinating and monitoring body for disaster management, to prepare a National Plan, monitor the implementation of National Policy etc.
Disaster Management Act 2005: Powers given to the Centre?
- Power bestowed by DM Act on Central Government and NDMA are extensive.
- The Central Government, irrespective of any law in force (including over-riding powers) can issue any directions to any authority anywhere in India to facilitate or assist in the disaster management.
- Importantly, any such directions issued by Central Government and NDMA must necessarily be followed
- In order to achieve all these, the prime minister can exercise all powers of NDMA (S 6(3)). This ensures that there is adequate political and constitutional heft behind the decisions made.
nationla Crisis Management Committee (NCMC)?
For effective implementation of relief measures in the wake of natural calamities, the Government of India has set up a Standing National Crisis Management Committee with Cabinet Secretary as Chairman.
Key functions:
- Oversee the Command, Control and Coordination of the disaster response.
- Give direction to the Crisis Management Group (CMG) as deemed necessary.
Amphan cyclone and Sunderbans?
- storm’s impact was devastating for the millions who live in the Sundarbans. About 28% of the Sunderbans has been damaged. Despite the massive plantation drives, it may take years to restore the mangroves.
- Cyclone Amphan, with wind speeds >170km/hr, passed directly through the Sundarbans, devastating it.
- Cyclone Amphan also damaged almost the entire length of the 100-kilometer (62-mile) nylon fence that had been erected to prevent tigers from straying into human habitations.
- Also led to breaking of embankments, resulting in salt water pouring onto the land. Saline water kills freshwater fish in ponds in a day, most sources of drinking water disappear, and land can’t be used for cultivation for up to five years.
- The coronvirus is complicating relief work as well. During the cyclone, villagers huddled in crowded storm shelters, which authorities feared could spread the virus.
Assam gas leak?
- natural gas flowing out of a gas well in Assam following a blowout at the Oil India Limited’s (OIL) Baghjan gas well in Assam’s Tinsukia district.
- close is the Maguri-Motapung wetland —an Important Bird Area notified by the Bombay Natural History Society.
- Dibru-Saikhowa National Park is at the distance of 900m
State Disaster Management Authority (SDMA)?
- All State Governments are mandated under Section 14 of the Disaster Management Act 2005 to establish a State Disaster Management Authority (SDMA).
- The SDMA consists of the Chief Minister of the State, who is the Chairperson, and no more than eight members appointed by the Chief Minister.
- In case of UTs, headed by LGs/Administrators
- State Executive Committee is responsible (Section 22) for drawing up the state disaster management plan, and implementing the National Plan.
- The SDMA is mandated under section 28 to ensure that all the departments of the State prepare disaster management plans as prescribed by the National and State Authorities
