COAL BED METHANE

BASICS

  • Coalbed methane (CBM or coal-bed methane)/ coalbed gas/coal seam gas (CSG), or coal-mine methane (CMM)[2] is a form of natural gas extracted from coal beds
  • CBM is natural gas trapped within coal formations, extracted by drilling holes into the seams.
  • mainly methane and trace quantities of ethanenitrogencarbon dioxide 
  • The term refers to methane adsorbed into the solid matrix of the coal. 
  • It is called 'sweet gas' because of its lack of hydrogen sulfide.
  • Unlike much natural gas from conventional reservoirs, coalbed methane contains very little heavier hydrocarbons such as propane or butane, and no natural-gas condensate. 
  • It often contains up to a few percent carbon dioxide
  • Some coal seams, such as those in certain areas of the Illawarra Coal Measures in NSW( Illawarra Coal Measures is a group of sedimentary rocks occurring in the Sydney), Australia, contain little methane, with the predominant coal seam gas being carbon dioxide.
  • it has become an important source of energy in United States, Canada, Australia,
INDIAN SCENARIO
  • Commercial CBM production in ONGC blocks is yet to start
LOCATIONS in india
  •  CBM gas from existing wells at Parbatpur of the Jharia block
Location in world

  • Australia
    • Commercial recovery of coal seam gas (CSG) began in Australia in 1996. As of 2013, coal seam gas, from Queensland and New South Wales, made up 10% percent of Australia's gas production. 
  • Canada

  • United Kingdom

    •  estimated to 2,900 billion cubic meters little as 1%might be economically recoverable.

  • United States
    •         United States coalbed methane production in 2011 was 1,76 trillion cubic feet (TCF), 7.3 percent of all US dry gas production that year.
    •  CBM production came from the Rocky Mountain states of Colorado, Wyoming, and New Mexico.
  • Kazakhstan
    •      Kazakhstan could witness the development of a large coalbed methane (CBM)

CO-OPERATIVE SECTOR


EVOLUTION IN INDIA
·         A cooperative ("coop") or co-operative ("co-op") is an autonomous association of  person who  voluntarily cooperate for their mutual social, economic, and cultural benefit.
·         The cooperative movement in India owes its origin to agriculture and allied sectors.
·         End of the 19th century, the problems of rural indebtedness and the consequent conditions of farmers created an environment for the chit funds and cooperative societies.
·          Cooperative movement was an attractive mechanism for pooling their meagre resources for solving common problems relating to credit, supplies of inputs and marketing of agricultural produce.
·         The experience gained in the working of cooperatives led to the enactment of Cooperative Credit Societies Act, 1904. Subsequently, a more comprehensive legislation called the Cooperative Societies Act was enacted.
·         Under the Montague-Chelmsford Reforms of 1919, cooperation became a provincial subject and the provinces were authorized to make their own cooperative laws.
·          Under the Government of India Act, 1935, cooperatives were treated as a provincial subject.
·         The item "Cooperative Societies" is a State Subject under entry No.32 of the State List of the Constitution of India.
·         In order to cover Cooperative Societies with membership from more than one province, the Government of India enacted the Multi-Unit Cooperative Societies Act, 1942.
·         With the emergence of national federations of cooperative societies in various functional areas and to obviate the plethora of different laws governing the same types of societies, a need was felt for a comprehensive Central legislation to consolidate the laws governing such cooperative societies. Therefore, the Multi-State Cooperative Societies Act, 1984 was enacted by Parliament under Entry No. 44 of the Union List of the Constitution of India.
·          After Independence cooperatives assumed a great significance in poverty removal and faster socio-economic growth.
·         Cooperatives became an integral part of the Five Year Plans.
·         In the 1st Five Year Plan stated that the success of the Plan would be judged by the extent it was implemented through cooperative organisations.
·         The All-India Rural Credit Survey Committee Report, 1954 recommended an integrated approach to cooperative credit.
·         In 1958 the National Development Council (NDC) had recommended a national policy on cooperatives. Jawaharlal Nehru had a strong faith in the cooperative movement.
·         During 1960s, further efforts were made to consolidate the cooperative societies by their re-organisation. Consequently, the number of primary agricultural cooperative credit societies was reduced from around 2lakh to 92,000. 
·         The number of all types of cooperatives increased from 1.81 lakh in 1950-51 to 4.53 lakh in 1996-97.
·         The cooperatives have been operating in various areas of the economy such as credit, production, processing, marketing, input distribution, housing, dairying and textiles. In some of the areas of their activities like dairying, urban banking and housing, sugar and handlooms, the cooperatives have achieved success to an extent but there are larger areas where they have not been so successful.
·         The failure of co-operatives in the country is mainly attributable to: dormant membership and lack of active participation of members in the management of cooperatives. Mounting overdues to cooperative credit institution, lack of mobilisation of internal resources and over-dependence on Government assistance, lack of professional management. Bureaucratic control and interference in the management, political interference and over-politisation have proved harmful to their growth. Predominance of vested interests resulting in non-percolation of benefits to a common member, particularly to the class of persons for whom such cooperatives were basically formed, has also retarded the development of cooperatives. These are the areas which need to be attended to by evolving suitable legislative and policy support. 

DRAWBACKS
·         Dormant membership and lack of active participation of members in the management of cooperatives.
·         Mounting over dues in cooperative credit institutions, lack of mobilization of internal resources and over dependence on government assistance, lack of professional management, bureaucratic control and interference in the management, political interference and over-politicization have proved harmful to their growth.
·         These are the areas which need to be attended to by evolving suitable legislative and policy support.
·         For the success of any developmental effort in the agricultural sector is to synergize with the efforts in the cooperative sector.
·         Cooperative sector of Indian economy has a spiritual content too when it was led by Vinoba Bhave.
·         Most of the financial institutions in the cooperative sector are also run on purely commercial basis diverting fro their social objectives.
WAY AHEAD AND SHARE OF CO-OPERATIVE
·         It is here that the State intervention can make the difference.
·         The grant, subsidies and aid meant for the poor farmers must be channeled through the cooperative sector.
·         Once there are enough resources in the sector in terms of money there will be increased participation by the people and will result in the all round development of the village.
·         Panchayat Raj institutions and cooperative sector can bring about positive change in the rural areas.
·         Cooperatives have extended across 230 million members nationwide.
·         The cooperative credit system largest network in the world and cooperatives has advanced more credit in the Indian agricultural sector than commercial banks.
·         Distribution the Indian Fertilizer Cooperative commands over 35% of the market.
·         In the production of sugar the cooperative share of the market is over 58% in cotton 60%.The cooperative sector accounts for 55% of the looms in the hand-weaving sector.
·         Cooperative process, market and distribute 50% of the edible oil.
·         Dairy cooperative operating under the leadership of the National Dairy Development Board become the largest producer of milk.
·         With the efforts of National Cooperative Union of India the Central Government passed the Multi State Cooperatives Societies Act and also formulated a national cooperative policy that provides greater autonomy to cooperatives.
·         With the passage of the Insurance Act, cooperatives have been allowed to enter into the insurance business. Insurance is a field where the immense potential of cooperatives still remains untapped.
·         In the new economic environment cooperatives at all levels are making efforts to reorient their functions according to the market demands.

·         Cooperatives are also considered to have immense potential to deliver goods and services in areas where both the state and the private sector have failed.

EBOLA VIRUS

  • Ebola virus disease (EVD), formerly known as Ebola haemorrhagic fever, is a severe, often fatal illness in humans.
  • Baron Peter Piot is a Belgian microbiologist known for his research into Ebola and AIDS he discoverred the Ebola virus in 1976.
  • EVD outbreaks have a case fatality rate of up to 90%.
  • EVD outbreaks occur primarily in remote villages in Central and West Africa, near tropical rainforests.
  • The virus is transmitted to people from wild animals(blood,bodily fluids) and spreads in the human population through human-to-human transmission.
  • Fruit bats of the Pteropodidae family are considered to be the natural host of the Ebola virus.
  • Severely ill patients require intensive supportive care. No licensed specific treatment or vaccine is available for use in people or animals.
  • First appeared in 1976 in 2 simultaneous outbreaks, in Nzara, Sudan and in Yambuku, Democratic Republic of Congo. The latter was in a village situated near the Ebola River, from which the disease takes its name
SYMPTOMS
  • The incubation period for Ebola is between 2 and 42 days. Patients are not contagious until they start to show signs of fever, aches, vomiting and diarrhoea.

INDIAN SCENARIO

  • There is a risk the deadly virus could be imported into the country
  • 45000 of Indians working in the four affected West African nations - working in Guinea, Liberia, Sierra Leone and Nigeria - where an outbreak of the disease has killed 932 people.
  • While the risk of Ebola virus cases in India is low, preparedness measures are in place to deal with any case of the virus imported to India. 
  • set up facilities at airports and ports to manage travelers showing symptoms of the disease.
  • State authorities have been instructed to designate hospitals with isolation wards for response to possible cases and to stock personal protective equipment.
DIFFICULTIES FOR INDIA To HANDLE EBOLA
  • High incubation period ranging from 30-42 days of ebola.
  • Symptons similar to malaria and dengu so difficult to seggregate ebola pateint.
  • Health center illequipped e.g center has disperesed only 50,000 ebola kit but insuffucient to handle such a vast population.
  • Human resource in health sector such as NURSES and WARD boys are illeuipped with jumpsuits and gloves to treat ebola pateint. Moreover India does not have enough experience to cure such contagious virus.
  • West bengal IDSP (Integrated Disease Survellience Program) mandated that outbrak of diease should gather information and send it out to health sectors but lack of infrastructure such as computers make it difficult.
  • Their are only two labs NCDC new delhi and National Institute of Virology (NIV) for studying virus.
GLOBAL SCENARIO
  • Ebola spreaded to U.S
  • Ebola spreaded to Europe first case founded in SPAIN.

    DISASTER MANAGEMENT IN SHORT

    #NATIONAL DISATER MANAGEMENT AUTHORITY
    • National Disaster Management Authority (NDMA) was established according to disaster management Act NDMA Act 2005 in year 2005 with the Prime Minister of India as chairperson.
    • The NDMA may have no more than nine members including a Vice-Chairperson. The tenure of the members of the NDMA shall be five years.
    • The NDMA is responsible for "laying down the policies, plans and guidelines for disaster management" and to ensure "timely and effective response to disaster".
    • The vice chairman has a rank of cabinet minister and other members have rank of union minister for state.

    #NDRF - National Disaster Response Force

    • The National Disaster Response Force (NDRF) is a disaster response agency under National Disaster Management Authority (NDMA) created by the Ministry of Home AffairsGovernment of India.
    • It was established in 2009 in Delhi, for disaster management and specialised response to naturaland man-made disasters.
    • Functioning at state and central-level under the National Disaster Management Authority (NDMA)
    •  it consists of 10 battalions of Central Armed Police Forces, including three each of the BSFCRPF, and two each of the CISF and ITBP.
    •  Each battalion will provide 18 self-contained specialist search and rescue teams of 45 personnel each including engineers, technicianselectriciansdog squads and medical/paramedics. The total strength of each battalion is approximately 1,149.
    • All the ten battalions are being equipped and trained to combat all natural disasters including four battalions in combating radiological, nuclearbiological and chemical disasters.
      PROBLEMS FACED BY NDRF
    •  NDRF has just 18 headquarters staff — another 83 personnel campared to National Security Guard, which hasn’t been deployed in combat since the 26/11 terror attacks six years ago, has 400 headquarters staff. Its chief has the power to requisition aircraft to move personnel in an emergency.
    • The director-general of the NDRF does not have that authority.
    • During kashmir floods NDRF had to wait for the Home Ministry for seeking air support fromthe armed forces — leading delays of 48 hours .
    • Part of the problem is the NDRF does not have a full-time boss. Even though the National Disaster Management Act provides for a director-general — reporting to the National Disaster Management Authority — the MHA sanctioned an additional director-general, using a vacancy created from the ranks of the Indo-Tibetan Border Police.
    • In the last seven years, the NDRF has had 15 directors-general.

    • Lack of logistics - In 2008, the MHA had sanctioned Rs 290 crore to equip eight battalions with a 310-piece United Nations-recommended disaster-response kit after which they are not updated. 
    • No permenant training facility

    • Plans drawn up by the NDMA, in consultation with top international and national experts. They specify exactly how disasters ought to be dealt with at the state and district levels and what kind of infrastructure needed at state and district level. These plans, however, have never been notified by the MHA through the Gazette of India. So there is no obligation on states to implement, or even consider, them. Funds flowed to states for creating infrastructure, but with no framework for implementing best practices.
    • Therefore, the district disaster plan for Udhampur, in Jammu and Kashmir, had no instructions for what to do if communications were knocked out by an earthquake or large flood, nor how resources were to be mobilised in a calamity.
    • Srinagar authorities had never once rehearsed for a disaster.
    • Legally, the NDMA has no authority to independently implement schemes; the MHA controls funding and execution. The NDMA thus remains just an advisory body, sending out missives few states pay attention to. Prime Minister Manmohan Singh, who was the chair of the NDMA, attended only three meetings, records show — and never intervened to push forward plans drawn up bearing his name. Now, Prime Minister Narendra Modi’s government has removed the organisation’s entire board — and there is no word when one might be appointed.
    • The natural disaster such as cyclone that occurs in one of the relativley poorer state liike orissa is illequipped to tackle disaster  at state level.

    TROPICAL CYCLONES

    # TROPICAL CYCLONE

    What is tropical cyclone?
    A tropical cyclone is a rotating, organized system of clouds and thunderstorms that originates over tropical or subtropical waters and has a closed low-level circulation. Tropical cyclones rotate counterclockwise in the Northern Hemisphere. They are classified as follows:
    • Tropical Depression: A tropical cyclone with maximum sustained winds of 38 mph (33 knots) or less.
    • Tropical Storm: A tropical cyclone with maximum sustained winds of 39 to 73 mph (34 to 63 knots).
    • Hurricane: A tropical cyclone with maximum sustained winds of 74 mph (64 knots) or higher. In the western North Pacific, hurricanes are called typhoons; similar storms in the Indian Ocean and South Pacific Ocean are called cyclones.
    • Major Hurricane: A tropical cyclone with maximum sustained winds of 111 mph (96 knots) or higher, corresponding to a Category 3, 4 or 5 on the Saffir-Simpson Hurricane Wind Scale.

    What causes Cyclones?

    • The main source of energy for tropical cyclones is the warm oceans in the tropical regions.
    • To initiate a tropical cyclone the sea-surface temperature generally needs to be above 26.5°C. However, existing cyclones often persist as they move over cooler waters.
    • The development of a tropical cyclone also relies on favourable broad-scale wind regimes and can persist for several days with many following quite erratic paths. They lose their source of energy when they move over land or colder oceans causing them to dissipate.
    • The point at which they cross land is called LANDFALL region.Weakening may also occur if the cyclone moves into an unfavourable wind regime which disrupts the structure of the system.
    • Sometimes a decaying tropical cyclone may interact with a weather system in higher latitudes to cause impacts far from the tropics.


    CHARACTERISTICS OF TROPICAL CYCLONE

    The most common features are destructive winds and heavy rainfall that can lead to flooding. Storm surge, or coastal inundation by seawater, is a lesser known phenomenon but can be the most dangerous element of a cyclone. Though rare in Australia, tornadoes have been reported during cyclone events.

    Severe wind

    •  wind gusts in excess of 90-360 km/h can be expected around their centre in eyewall
    • strongest winds are near the eye, damaging winds can extend hundreds of kilometres from the centre.
    • The eye can have quite calm winds and cloud-free skies, but this lull is temporary and is followed by destructive winds from another direction.
    • This is because, from above, the winds spiral around the eye in a clockwise direction (in the Southern Hemisphere). The effect of this on the ground is that winds on opposite sides of the eye blow in different directions.
    • Wind damage is mostly caused by the maximum gusts in the cyclone. For this reason, the well-known tropical cyclone severity categories used by the Bureau of Meteorology to communicate warnings are based on maximum gust strengths.
    Heavy rainfall
    •  heavy rainfall over extensive areas.
    • Rain can create severe impacts by causing floods and landslides.
    Storm surge
    • Storm surge is a rising of the sea as a result of wind and atmospheric pressure changes associated with a storm.
    • It is caused by a combination of strong winds driving water onshore and the lower atmospheric pressure in a tropical cyclone. In the southern hemisphere the onshore winds occur to the left of the tropical cyclone's path.
    • In Australia, this is the east side on the north west and north coasts and the south side on the east coast.
    • The largest surge usually extends between 30 and 60 kilometres from the crossing point of the tropical cyclone centre, or eye. Its influence also depends on the local topography of the seafloor and the angle at which the cyclone crosses the coast.
    • If the surge occurs at the same time as a high astronomical tide the area inundated can be extensive, particularly along low-lying coastlines.


    DISTRUBUTION OVER THE GLOBE



    • The six tropical cyclone Regional Specialized Meteorological Centres (RSMCs) together with six Tropical Cyclone Warning Centres (TCWCs) having regional responsibility, provide advisories and bulletins with up-to-date first level basic meteorological information on all tropical cyclones, hurricanes, typhoons everywhere in the world.


    • The western Pacific is the most active and the north Indian the least active. An average of 86 tropical cyclones of tropical storm intensity form annually worldwide, with 47 reaching hurricane/typhoon strength, and 20 becoming intense tropical cyclones .
    INDIAN SCENARIO REGARDING TROPICAL CYCLONE
    North Indian Ocean
    • This basin is divided into two areas: the Bay of Bengal and the Arabian Sea, with the Bay of Bengal dominating (5 to 6 times more activity). Still, this basin is the most inactive worldwide, with only 4 to 6 storms per year.
    • This basin's season has a double peak: one in April and May, before the onset of the monsoon, and another in October and November, just after
    •  Although it is an inactive basin, the deadliest tropical cyclones in the world have formed here, including the 1970 Bhola cyclone, which killed 500,000 people.
    • Nations affected include India,BangladeshSri LankaThailandMyanmar, and Pakistan. Rarely do tropical cyclones that form in this basin affect the Arabian Peninsula orSomalia; however, Cyclone Gonu caused heavy damage in Oman on the peninsula in 2007.
    South-West Indian Ocean

    • The South-West Indian Ocean is located within the Southern Hemisphere between the Africa's east coast and 90°E and is primarily monitored by the Meteo France's La Reunion RSMC, while the Mauritian, Australian Indonesian, and Madagascan weather services also monitor parts of it.
    •  Until the start of the 1985-86 tropical cyclone season the basin only extended to 80°E, with the 10 degrees between 80 and 90E considered to be a part of the Australian region.
    •  On average about 9 cyclones per develop into tropical storms, while 5 of those go on to become tropical cyclones that are equivalent to a hurricane or a typhoon.
    •  The tropical cyclones that form in this area can affect some of the various Indian Ocean island nations and or various countries along Africa's east coast.
      Cyclonic storm Hudhud
    Cyclonic storm Hudhud is building over the Bay of Bengal and is likely to bring torrential rains and strong wind to the region over the next few days. The name Hudhud has been given by Oman, and it is derived from the name of an Afro-Eurasian bird.

           Preparations for Hudhud

         The cyclone is scheduled to hit the Odisha coast by October 12. It is also expected to hit the Andhra             Pradesh coastline. However, it will not directly hitWest Bengal, though the state is expected to feel the         impacts of the cyclone. The states in the Bay of Bengal region have issued warnings asking fishermen not to venture deep into the sea.
    The intensity of Hudhud is expected to be on the lines of that of cyclone Phailin which hit Odisha last year.

    Evolution of Hudhud

    Hudhud first appeared as a low pressure are over the South Myanmar coast adjoining Andaman Sea. This evolved in to a depression around 250 km east of Port Blair on 6 October. This depression is expected to intensify into a cyclonic circulation by 8 October. The immediate effect of the cyclone formation will obviously be felt on the Andaman & Nicobar Island where heavy rains and minor damage to loose and unsecured structures have been predicted. After crossing the Andamans, the cyclonic circulation is expected to south-west into the Bay of Bengal and take shape of a cyclonic storm.

    The chief reason behind it is that Andhra Pradesh falls in the 12,000-km coastline within South Asia, which is vulnerable to cyclones. Over 95 per cent of the major cyclonic disasters experienced in the world have taken place in the region. And the incidence of cyclones is more in the Bay of Bengal when compared to the Arabian Sea. While the recurring disasters of different sorts have had a severe impact on the State’s economy and policies, the dilly dallying of government machinery played havoc with payment of compensation due to farmers. The glaring example of this can be attributed to the latest cyclone Phailin and the related compensation which is unpaid. The government officials could, with great difficulty, reach the cyclone-hit districts several months after its occurrence. And the farmers are still waiting for the damages incurred in the Phailin cyclone that hit crops in 2013.


    JAPAN - Tropical cyclone VONGFONG
    • After crossing Okinawa, on 12 October VONGFONG turned north-east and made landfall in southern Kagoshima prefecture on Kyushu island, overnight 12-13 October; then it moved over Shikoku Island in the morning of 13 October. Strong winds, heavy rain and storm surge affected parts of south-western Japan.
    • As of 13 October, media reported one person missing and 68 injured (23 of them in Okinawa).
    • In the next 24 h it is forecast to move north-east over Honshu island, weakening further. As of 13 October (JMA), there are warnings in effect for heavy rain, floods, storms and high waves for parts of Okinawa, Kyushu, Shikoku and Honshu.
