GS Paper: GS3-18.Conservation, Environmental Pollution and Degradation, Environmental Impact Assessment.

  • Towards cleaner air in Delhi

    The article suggests the three-pronged strategy to deal with the emission from transportation and highlights the importance of coordination at various level to deal with the issue of pollution.

    Anti-pollution campaign in Delhi

    • With air pollution returning to pre-COVID levels, the Delhi administration has launched a major anti-pollution campaign this month.
    • The campaign is focused on cutting the deadly smoke from thermal plants and brick kilns in the National Capital Region as well as on chemical treatment of stubble burning from nearby States.

    Abating emission from transportation

    • Delhi’s long-term solution will depend importantly also on abating emissions from transportation.
    • Delhi needs a 65% reduction to meet the national standards for PM2.5.
    • Vehicles, including trucks and two-wheelers, contribute 20%-40% of the PM2.5 concentrations.
    • Tackling vehicle emissions would be one part of the agenda, as in comparable situations in Bangkok, Beijing, and Mexico City.

    Three-part action to combat emissions from transportation

    • A three-part action comprises emissions standards, public transport, and electric vehicles.

    1) Stricter enforcement of emission controls

    • Two-wheelers and three-wheelers were as important as cars and lorries in Beijing’s experience.
    • Bangkok ramped up inspection and maintenance to cut emissions.
    • The first order of business is to implement the national standards.

    2) Strengthening public transport

    • Bus Rapid Transit (BRT)  around the world show how the sizeable investment cost is more than offset by the benefits, and that financing pays off.
    • Delhi has lessons from its BRT experience in designating better BRT lanes, improving the ticketing system and synchronising with the Metro.
    • The Supreme Court’s ruling to increase Delhi’s bus fleet and align it with the Metro network must be carried out.
    • The ‘odd-even’ number plate policy can help, but the system should reduce exemptions, allow a longer implementation period, and complement it with other measures.

    3) Adoption of electric vehicle: A long term solution

    •  Subsidies and investment will be needed to ensure that EVs are used to a meaningful scale.
    • The Delhi government’s three-year policy aims to make EVs account for a quarter of the new vehicles registered in the capital by 2024.
    • EVs will gain from purchase incentives, scrappage benefits on older vehicles, loans at favourable interest and a waiver of road taxes.

    Need for coordination at various level

    • Transport solutions need to be one part of pollution abatement that includes industry and agriculture.
    • Delhi’s own actions will not work if the pollution from neighbouring States is not addressed head on.
    • Technical solutions need to be underpinned by coordination and transparency across Central, State, and local governments.
    • Public opinion matters.
    • Citizen participation and the media are vital for sharing the message on pollution and health, using data such as those from the Central Pollution Control Board.

    Conclusion

    • It is a matter of prioritising people’s health and a brighter future. Once the pandemic is over, Delhi must not stumble into yet another public health emergency. The time to act is now.

  • 8 Indian beaches accorded ‘Blue Flag’ tag

    Eight Indian beaches have got an International Blue Flag Certification, said Union Minister of Environment, Forest and Climate Change.

    Note the beaches and their respective states. They can be asked in the ”match the pairs” type questions.

    Citation needed: *As of now, there are 13 Blue flag awarded beaches in India a/c to wikipedia. But Blue Flag website would provide exact figures (which yet to update the official numbers).

    Which are these beaches?

    1. Shivrajpur (Dwarka-Gujarat)
    2. Ghoghla (Diu)
    3. Kasarkod [NOT Kasargod which is in Kerala] and Padubidri (Karnataka)
    4. Kappad (Kerala)
    5. Rushikonda (AP)
    6. Golden Beach (Odisha) and
    7. Radhanagar (A&N Islands)

    Blue Flag Beaches

    • The ‘Blue Flag’ beach is an ‘eco-tourism model’ and marks out beaches as providing tourists and beachgoers clean and hygienic bathing water, facilities/amenities, a safe and healthy environment, and sustainable development of the area.
    • The certification is accorded by the Denmark-based Foundation for Environment Education.
    • It started in France in 1985 and has been implemented in Europe since 1987, and in areas outside Europe since 2001 when South Africa joined.
    • It has 33 stringent criteria under four major heads for the beaches, that is, (i) Environmental Education and Information (ii) Bathing Water Quality (iii) Environment Management and Conservation and (iv) Safety and Services.

  • Species in news: Aenigmachanna Gollum

    Scientists have discovered a new family of bony fish from the Western Ghats and named it Aenigmachannidae.

    A stand-alone species being mentioned in the news for the first time (and that too from Southern India) find their way into the prelims. Make special note here. Usually, note the species and its habitat location (IUCN status if available), in the purview of a generic prelims question.

    Aenigmachannidae

    • Aenigmachanna Gollum has a surprisingly large number of primitive characters, and detailed molecular phylogenetic analyses including of its Mitochondrial DNA suggested an ancient separation from Channidae.
    • Many such species were earlier found in the aquifers of Kerala.
    • Many of these species are blind, pigment-less, and have peculiar morphological characters that are otherwise not seen in species occurring in surface waters.

    Significance of the discovery

    • The presence of two unique endemic families of freshwater fish in a small region like Kerala is unparalleled and indicates the exceptional diversity and endemicity of fishes in this part of the world.
    • The members of Aenigmachannidae are “living fossils” and comprise an ancient Gondwanan lineage that survived the break-up of the supercontinent and the northward drift of the Indian subcontinent.

  • 3 contenders for National Butterfly Status

    A citizen poll to identify the national butterfly concluded with three species garnering the highest number of votes.

    Q.With reference to India’s Biodiversity, Ceylon frogmouth, Coppersmith barbet, Gray-chinned minivet and White-throated redstart are-
    (a) Birds
    (b) Primates
    (c) Reptiles
    (d) Amphibians

    Which are the three species?

    (1) Indian Jezebel

    • Blessed with a vibrant colour pattern, including vermilion (Haldi – kumkum), the Indian Jezebel (or Common Jezebel) is known to deter its predators with its flashy wing colours.
    • Regarded as soldiers of farmers, they also prey on parasites that infest fruit-bearing plants.
    • Widely distributed, the species can be spotted in gardens and other lightly wooded areas.

    (2) Krishna Peacock

    • It is a flagship species for biodiversity and conservation, generally found in large numbers in the Himalayas.
    • Possessing a peculiarly large swallowtail, its iridescent green scales diffract light to coat itself in radiance.

    (3) Orange Oakleaf

    • It is commonly known as ‘dead leaf’ for its ability to camouflage as a dry autumn leaf while striking a stationary pose with its wings closed.
    • The masquerade enables the species to prevent it from being devoured by birds in the moist forests of the northern Western Ghats, central, northern and northeastern parts of India where they are generally found.
    • Besides, the Oakleaf is also known to exhibit polyphenism as it assumes specific colour and size during dry and wet seasons.

  • What is Graded Response Action Plan (GRAP)?

    The Supreme Court has directed Delhi and neighbouring States to implement air pollution control measures under “very poor” and “severe” category air quality of the Graded Response Action Plan (GRAP).

    Note the various measures under the GRAP under various grades of Air Quality.

    Graded Response Action Plan (GRAP)

    • In 2014, when a study by the WHO found that Delhi was the most polluted city in the world, panic spread in the Centre and the state government.
    • Approved by the Supreme Court in 2016, the plan was formulated after several meetings that the Environment Pollution (Prevention and Control) Authority (EPCA) held with state government and experts.
    • The result was a plan that institutionalized measures to be taken when air quality deteriorates.
    • GRAP works only as an emergency measure.

    How does it work?

    • As such, the plan does not include action by various state governments to be taken throughout the year to tackle industrial, vehicular and combustion emissions.
    • When the air quality shifts from poor to very poor, the measures listed under both sections have to be followed since the plan is incremental in nature.
    • If air quality reaches the severe+ stage, GRAP talks about shutting down schools and implementing the odd-even road-space rationing scheme.

    Measures taken under GRAP

    1)Severe+ or Emergency

    (PM 2.5 over 300 µg/cubic metre or PM10 over 500 µg/cu. m. for 48+ hours)

    • Stop entry of trucks into Delhi (except essential commodities)
    • Stop construction work
    • Introduce odd/even scheme for private vehicles and minimise exemptions
    • Task Force to decide any additional steps including shutting of schools

    2) Severe

    (PM 2.5 over 250 µg/cu. m. or PM10 over 430 µg/cu. m.)

    • Close brick kilns, hot mix plants, stone crushers
    • Maximise power generation from natural gas to reduce generation from coal
    • Encourage public transport, with differential rates
    • More frequent mechanized cleaning of road and sprinkling of water

    3) Very Poor

    (PM2.5 121-250 µg/cu. m. or PM10 351-430 µg/cu. m.)

    • Stop use of diesel generator sets
    • Enhance parking fee by 3-4 times
    • Increase bus and Metro services
    • Apartment owners to discourage burning fires in winter by providing electric heaters during winter
    • Advisories to people with respiratory and cardiac conditions to restrict outdoor movement

    4) Moderate to poor

    (PM2.5 61-120 µg/cu. m. or PM10 101-350 µg/cu. m.)

    • Heavy fines for garbage burning
    • Close/enforce pollution control regulations in brick kilns and industries
    • Mechanized sweeping on roads with heavy traffic and water sprinkling
    • Strictly enforce a ban on firecrackers

    Has GRAP helped?

    • The biggest success of GRAP has been in fixing accountability and deadlines.
    • For each action to be taken under a particular air quality category, executing agencies are clearly marked.
    • In a territory like Delhi, where a multiplicity of authorities has been a long-standing impediment to effective governance, this step made a crucial difference.

  • Species in news: Abortelphusa Namdaphaensis

    A crab specie was recently named after Arunachal Pradesh’s pristine forests on the edge of a small stream in Namdapha Tiger Reserve.

    Try this question from CSP 2020:

    Q.With reference to India’s Biodiversity, Ceylon frogmouth, Coppersmith barbet, Gray-chinned minivet and White-throated redstart are:

    (a) Birds
    (b) Primates
    (c) Reptiles
    (d) Amphibians

    Abortelphusa Namdaphaensis

    • The species, a small freshwater crab species, is a tribute to Namdapha, the largest protected area in the Eastern Himalayan Biodiversity Hotspot and the Abor Hills.
    • It is the first Gecarcinucidae to be found in the Himalayan region. Freshwater crabs are divided into two families/categories: Potamidae and Gecarcinucidae.
    • Both differ in abdomen shape and size. Potamidae species have a broad triangular abdomen, whereas, in Gecarcinucidae, the abdomen is mostly T-shaped.
    • While the Gecarcinucidae is found in the peninsular region, the Western Ghats and the Eastern Ghats, Potamidae are found in the Himalayan region.

    What makes it special?

    • The new species was found in a dry area, despite being a “freshwater” crab.
    • Freshwater crabs use their gills to absorb dissolved oxygen from water, but for food, breeding, and other purposes, they do not need water, and thus roam on the land near water.
    • The only reason it was possible to spot this on land is that the habitat around the water body has been preserved, untouched even.
    • Of the 125 freshwater crabs in India, the north-east accounts for 37. Arunachal Pradesh has 15 and Assam has 21.
    • The discovery highlights the potential of Arunachal Pradesh as one of the richest biodiversity hotspots in the country.

    Back2Basics: Namdapha

    • Namdapha (named a National Park in 1983) is known for its rich biodiversity and believed to be the rare area that harbours four large cats: tigers, snow leopards, clouded leopards and leopards.
    • The Abor Hills, bordered by the Mishmi Hills and Miri Hills, is historically known for the Abor Expedition.
    • It is a punitive expedition against the Abors in the North-Eastern Frontier Agency (which corresponds to parts of present-day Assam and Arunachal Pradesh) from October 1911 to April 1912.
    • The expedition had thrown up a plethora of new floral and faunal species, making it a zoological and botanical expedition as well.

  • [pib] Stockholm Convention on Persistent Organic Pollutants (POPs)

    The Union Cabinet has approved the Ratification of seven chemicals listed under the Stockholm Convention on Persistent Organic Pollutants (POPs).

    Stockholm Convention

    • It is a global treaty to protect human health and environment from POPs, which are identified chemical substances that persist in the environment, bio-accumulate in living organisms, adversely affect human health/ environment and have the property of long-range environmental transport (LRET).

    Key Provisions:  The provisions of the Convention require each party to:

    • Prohibit and/or eliminate the production and use, as well as the import and export, of the intentionally, produced POPs that are listed in Annex A to the Convention
    • Restrict the production and use, as well as the import and export, of the intentionally, produced POPs that are listed in Annex B to the Convention
    • Reduce or eliminate releases from unintentionally produced POPs that are listed in Annex C to the Convention
    • Ensure that stockpiles and wastes consisting of, containing or contaminated with POPs are managed safely and in an environmentally sound manner

    Do you know?

    The Global Environment Facility (GEF) serves as a financial mechanism for the following conventions:

    1. Convention on Biological Diversity (CBD)
    2. United Nations Framework Convention on Climate Change (UNFCCC)
    3. UN Convention to Combat Desertification (UNCCD)
    4. Stockholm Convention on Persistent Organic Pollutants (POPs)
    5. Minamata Convention on Mercury

    What are POPs?

    • Persistent organic pollutants (POPs), sometimes known as “forever chemicals” are organic compounds that are resistant to environmental degradation through chemical, biological, and photolytic processes.
    • Because of their persistence, POPs bioaccumulate with potential adverse impacts on human health and the environment.
    • Many POPs are currently or were in the past used as pesticides, solvents, pharmaceuticals, and industrial chemicals.
    • Although some POPs arise naturally (e.g from volcanoes), most are man-made via total synthesis.

    Threats of POPs

    • Exposure to POPs can lead to cancer, damage to central & peripheral nervous systems, diseases of the immune system, reproductive disorders and interference with normal infant and child development.

    India’s actions on POPs till now

    • The MoEFCC had notified the ‘Regulation of Persistent Organic Pollutants Rules, on March 5, 2018, under the provisions of Environment (Protection) Act, 1986.
    • The regulation prohibited the manufacture, trade, use, import and export seven chemicals which were already listed as POPs under Stockholm Convention-
    1. Chlordecone
    2. Hexabromobiphenyl
    3. Hexabromodiphenyl ether and Heptabromodiphenylether (Commercial octa-BDE)
    4. Tetrabromodiphenyl ether and Pentabromodiphenyl ether (Commercial Penta-BDE)
    5. Pentachlorobenzene
    6. Hexabromocyclododecane and
    7. Hexachlorobutadiene

  • Species in news: Madhuca Diplostemon

    Which of the above statements is/ are correct?

    (a) 1 only

    (b) 2 only

    (c) Both 1 and 2

    (d) Neither 1 nor 2

    Madhuca diplostemon

    • Scientists have identified the tree as Madhuca diplostemon (family Sapotaceae), a threatened species of the Western Ghats whose specimen was first collected in 1835.
    • In 1835, Robert Wight, a surgeon-botanist with the East India Company, had collected three specimens of the species.
    • Only one mature tree has been found so far, which makes this remarkable rediscovery extremely valuable from a scientific, environmental and conservation point of view.
    • Since the species is represented only by one specimen in a single locality, it is eligible to be categorised ‘Critically Endangered’ by the IUCN.

  • Wildlife Week

    Celebrating Wildlife Week

    • Wildlife Week is celebrated every year in India between October 1 and 8.
    • The annual theme of the campaign is to promote the preservation of fauna – i.e. animal life.
    • Wildlife Week was conceptualized in 1952 with the overall goal of raising awareness to serve the long-term goal of safeguarding the lives of wildlife through critical action.
    • In addition, the Indian Government established an Indian Board of Wild Life which works to improve awareness towards the preservation of wildlife.
