  • Species in news: Septemeranthus

    A new genus of a parasitic flowering plant has recently been discovered from the Nicobar group of islands.

    Septemeranthus

    • The genus Septemeranthus grows on the plant species Horsfieldia glabra (Blume) Warb.
    • The parasitic flowering plants have a modified root structure spread on the stem of the tree and are anchored inside the bark of the host tree.
    • It has a distinct vegetative morphology, inflorescence architecture and floral characters.
    • The leaves of the plant are heart-shaped with a very long tip and the ovary,fruit and seeds are ‘urceolate’ (earthen pot-shaped).
    • Birds consume viscous seeds of this new genus and seeds have potential of pseudo viviparous germination that deposit on the leaves and branches of their same plant which is already attached to host plants.

    Key features

    • They need a host tree or shrub in order to thrive and exhibit a worldwide distribution in tropical as well as temperate habitats.
    • They are important in forest ecology, pathology and medicine.
    • They play an important role as they provide food for frugivorous birds.

  • What is Pollution-Under-Control (PUC) Certificate?

    Delhi govt will soon make PUC certificate mandatory for fuel at filling stations.

    What is PUC Certificate?

    • The PUC certificate is a document that any person driving a motor vehicle can be asked to produce by a police officer in uniform authorized by the state government.
    • These issue certificates if a vehicle is found complying with the prescribed emission norms.
    • Since the Motor Vehicles (Amendment) Act, 2019 came into force, PUC certificate has been made mandatory.
    • A PUC certificate contains information such as the vehicle’s license plate number, PUC test reading, date on which the PUC test was conducted and the expiry date.

    How is a pollution control check carried out?

    • The computerized model for pollution check was developed by the Society of Indian Automobile manufacturers.
    • A gas analyzer is connected to a computer, to which a camera and a printer are attached.
    • The gas analyzer records the emission value and sends it to the computer directly, while the camera captures the license plate of the vehicle.
    • Subsequently, a certificate may be issued if the emission values are within the limits.

    Fines for non-compliance

    • The test costs between Rs 60 and Rs 100.
    • The validity of the test is one year for BS IV vehicles and three months for others.
    • The fine for PUC violations has now gone up to Rs 10,000; it used to be Rs 1,000 for the first offence and Rs 2,000 for subsequent violations before the amendments came into force.

  • Towards low emissions growth

    Context

    While many developing countries made net-zero pledges at COP26 in Glasgow, they face enormous developmental challenges in their attempts to grow in a climate-constrained world.

    Developmental challenges for India

    • For India, the national context is shaped by high youth unemployment, millions more entering the workforce each year, and a country hungry for substantial investments in hard infrastructure to industrialise and urbanise.
    • Growth with low emission footprint: India’s economic growth in the last three decades, led by growth in the services sector, has come at a significantly lower emissions footprint.
    • But in the coming decades, India will have to move to an investment-led and manufacturing-intensive growth model to create job opportunities and create entirely new cities and infrastructure to accommodate and connect an increasingly urban population.
    •  All of this requires a lot of energy. Can India do all of this with a low emissions footprint?

    What could India do to pursue an industrialization pathway that is climate-compatible?

    • A coherent national transition strategy is important in a global context where industrialised countries are discussing the imposition of carbon border taxes while failing to provide developing countries the necessary carbon space to grow or the finance and technological assistance necessary to decarbonise.
    • What India needs is an overarching green industrialisation strategy that combines laws, policy instruments, and new or reformed implementing institutions to steer its decentralised economic activities to become climate-friendly and resilient.

    Issues with India’s domestic manufacturing of renewable technology components

    • India’s industrial policy efforts to increase the domestic manufacturing of renewable energy technology components have been affected by policy incoherence, poor management of economic rents, and contradictory policy objectives.
    • India managed to create just a third of jobs per megawatt that China has managed to in its efforts to promote solar PV and wind technologies.
    • China has created more jobs in manufacturing solar and wind components for exports than domestic deployment.
    • India could have retained some of those jobs if it were strategic in promoting these technologies.

    Opportunities in decarbonising transport and industry sector

    • Technologies needed to decarbonise the transport and industry sectors provide a significant opportunity for India.
    • However, India’s R&D investments in these emerging green technologies are non-existent.
    • PLI is a step in right direction: The production-linked incentives (PLIs) under ‘Aatmanirbhar Bharat’ are a step in the right direction for localising clean energy manufacturing activities.
    • Focus on R&D: Aligning existing RD&D investments with the technologies needed for green industrialisation is crucial for realising quantum jumps in economic activities.
    • Encourage private entrepreneurship: India also needs to nurture private entrepreneurship and experimentation in clean energy technologies.
    • Besides China, Korea’s green growth strategy provide examples of how India could gain economic and employment rents from green industrialisation without implementing restrictive policies.

    Way forward

    • India should set its pace based on its ability to capitalise on the opportunities to create wealth through green industrialisation.
    • India should follow a path where it can negotiate carbon space to grow, buying time for the hard-to-abate sectors; push against counterproductive WTO trade litigations on decarbonisation technologies; all while making R&D investments in those technologies to ensure that it can gain economic value in the transition.

    Consider the question “What are the challenges India faces as it strives to reach the goal of net-zero emission by 2070. Suggest the strategy India should follow to maximise the developmental gains.”

    Conclusion

    The government should neither succumb to international pressure to decarbonise soon nor should it postpone its investment in decarbonisation technologies and lose its long-term competitiveness in a global low-carbon economy.

  • A proposal for Indian Environmental Service

    The Supreme Court has asked the Government if it will create an Indian Environmental Service (IES) as recommended by a committee headed by former Cabinet secretary T.S.R Subramanian in 2014.

    Why is the IES debate back in the news?

    • The Supreme Court was responding to a petition whose counsel pointed out that the matters of environment required special expertise.
    • Currently, matters of environmental regulation rest on scientists of the Ministry of Environment and Forests as well as bureaucrats from the Indian Administrative Services (IAS).
    • The apex court expressed reluctance at getting into administrative matters of the Government but nevertheless asked the Centre if it expects to go about constituting such a mechanism.

    TSR Subramanian Committee Report on Environment

    • The Subramanian committee was set up in August 2014 to review the country’s green laws and the procedures followed by the Ministry of Environment, Forest and Climate Change (MoEF&CC).
    • It suggested several amendments to align with the Government’s economic development agenda.
    • The report had suggested amendments to almost all green laws, including those relating to the environment, forest, wildlife and coastal zone clearances.
    • The committee suggested that another committee, with more expertise and time, be constituted to review the environmental laws.

    Key recommendations

    (a) Establishment of Environment Management Authorities

    • The report proposed an ‘Environmental Laws (Management) Act’ (ELMA), that envisioned full-time expert bodies to be constituted at the Central and State levels respectively:
    1. National Environmental Management Authority (NEMA)
    2. State Environmental Management Authority (SEMA)

    (b) Project clearances

    • These authorities evaluate project clearance (using technology and expertise), in a time bound manner, providing for single-window clearance.
    • It suggested a “fast track” procedure for “linear” projects (roads, railways and transmission lines), power and mining projects and for “projects of national importance.”
    • It also suggested an appellate mechanism against the decisions of NEMA/SEMA or MoEF&CC, in respect of project clearance, prescribing a three-month deadline to dispose appeals.

    (c) Expanding Environment Protection Act

    • The Air Act and the Water Act is to be subsumed within the EP Act.
    • The existing Central Pollution Control Board and the State PCBs, which monitor and regulate the conditions imposed on the industries to safeguard environment be integrated into NEMA and SEMA.

    (d) Evaluating Environmental Reconstruction Cost (ERC)

    • The report also recommends that an “ERC” should be assessed for each project on the basis of the damage caused by it to the environment and this should be added into the cost of the project.
    • This cost has to be recovered as a cess or duty from the project proponent during the life of the project.

    (e) Research and Development

    • It proposed the establishment of a National Environment Research institute “on the lines of the Indian Council of Forestry Research and Education”.
    • It would bring in the application of high-end technology in environment governance.

    (f) Establishment of Indian Environment Service (IES)

    • Finally, an Indian Environment Service should be established to recruit qualified and skilled human resource in the environment sector.

    How were the recommendations received?

    • The Centre never formally accepted this report and neither constituted a new committee as recommended by the Parliamentary Standing Committee.
    • The Parliamentary rejected the report on the grounds that it ended up diluting key aspects of environmental legislation designed to protect the environment.
    • However, many of these recommendations are implicitly making their way into the process of environmental regulation.

    Back2Basics: All Indi Services

    • The All India Services (AIS) comprises three civil services: the Indian Administrative Service, the Indian Police Service and the Indian Forest Service.
    • A unique feature of the AIS is that the members of these services are recruited by the centre (Union government in federal polity), but their services are placed under various State cadres.
    • They have the liability to serve both under the State and under the centre.
    • Officers of these three services comply to the All India Services Rules relating to pay, conduct, leave, various allowances etc.
    • The All India Services Act, 1951, provides for the creation of two more All India Services, namely, the Indian Engineering Service and the Indian Medical Service.

  • Kerala gets its first-ever Scientific Bird Atlas

    The Kerala Bird Atlas (KBA), the first-of-its-kind State-level bird atlas in India, has created solid baseline data about the distribution and abundance of bird species across all major habitats, giving an impetus to futuristic studies.

    Kerala Bird Atlas (KBA)

    • The KBA has been prepared based on systematic surveys held twice over 60 days a year during the wet (July to September) and dry (January to March) seasons between 2015 and 2020.
    • It was conducted as a citizen science-driven exercise with the participation of over 1,000 volunteers of the birdwatching community.
    • The KBA accounts for nearly three lakh records of 361 species, including 94 very rare species, 103 rare species, 110 common species, 44 very common species, and 10 most abundant species.
    • It was found that the species count was higher during the dry season than in the wet season while species richness and evenness were higher in the northern and central districts than in the southern districts.

    Significance of KBA

    • The KBA offers authentic, consistent and comparable data through random sampling from the geographical terrain split.
    • It is arguably Asia’s largest bird atlas in terms of geographical extent, sampling effort and species coverage derived from the aggregation of 25,000 checklists.
    • The KBA is considered to be a valuable resource for testing various ecological hypotheses and suggesting science-backed conservation measures.

  • Declaration on Forests and Land Use

    At COP-26 in Glasgow, countries got together to sign the Declaration on Forests and Land Use (or the Deforestation Declaration). However, India was among the few countries that did not sign the declaration.

    What is this Deforestation Declaration?

    • It was signed by 142 countries, which represented over 90 percent of forests across the world.
    • The declaration commits to halt and reverse forest loss and land degradation by 2030 while delivering sustainable development and promoting an inclusive rural transformation.
    • The signatories committed $19 billion in private and public funds to this end.

    Why did India abstain from joining?

    • India had concerns about the linkage the declaration makes between deforestation, infrastructure development and trade.
    • Any commitment to the environment and climate change should not involve any reference to trade, cited India.
    • Analysts in India have linked the decision to a proposed amendment to the Forest Conservation Act 1980 that would ease the clearances presently required for acquiring forest land for new infrastructure projects.

    India abstained from many things

    • A look at India’s positions on some other recent critical pledges and decisions related to climate change reveals a clear pattern of objections or absence.
    • At CoP26, India was not part of the dialogue on Forests, Agriculture and Commodity Trade (FACT).
    • FACT, which is supported by 28 countries seeks to encourage “sustainable development and trade of agricultural commodities while protecting and managing sustainably forests and other critical ecosystems”.
    • India also voted against a recent draft resolution to allow for discussions related to climate change and its impact on international peace and security to be taken up at the UNSC.

    Why should India join this declaration?

    • Broadly speaking, all of India’s objections are based on procedural issues at multilateral fora.
    • Although justifiable on paper, these objections seem blind to the diverse ways in which climate change is linked to global trade, deforestation, agriculture, and international peace, among other issues.
    • For context, consider India’s palm oil trade. India is the largest importer of crude palm oil in the world.
    • Palm oil cultivation, covering roughly 16 million acres of land in Indonesia and Malaysia, has been the biggest driver of deforestation in the two countries.

  • Species in news: Swamp Deer

    The population of the vulnerable eastern swamp deer, extinct elsewhere in South Asia, has dipped (from 907 in 2018 to 868 in 2020 ) in the Kaziranga National Park and Tiger Reserve.

    Swamp Deer

    • The swamp deer also called as barasingha is a deer species distributed in the Indian subcontinent.
    • Populations in northern and central India are fragmented, and two isolated populations occur in southwestern Nepal.
    • It has been locally extinct in Pakistan and Bangladesh, and its presence is uncertain in Bhutan.
    • In Assamese, barasingha is called dolhorina; dol meaning swamp.

    Note: Swamp deers do occur in the Kanha National Park of Madhya Pradesh, in two localities in Assam, and in only 6 localities in Uttar Pradesh.

  • Species in news: Miss Kerala

    A section of aquarists and ornamental fish breeders are surprised that the Denison barb (Miss Kerala), a native freshwater fish species commonly found in parts of Karnataka and Kerala, has been included in Schedule I of the Wild Life Protection Act, 1982 (amendment bill).

    Miss Kerala

    • Miss Kerala is also known as Denison barb, red-line torpedo barb and roseline shark.
    • Its scientific name is Sahyadria denisonii.
    • The fish is featured with red and black stripes on its body.
    • It is found in the States of Kerala and Karnataka.
    • It has been listed on the IUCN Redlist as Vulnerable, in 2010.
    • This species is known to inhabit fast-flowing hill streams and is often found in rocky pools with thick vegetation along river banks.

    Why included in Schedule I of WPA?

    • Ironically, its beauty is the biggest threat to its survival, as it is highly sought-after in the international aquarium trade, constituting 60 – 65% of the total live ornamental fish exported from India.
    • Its numbers are also decreasing owing to habitat degradation due to deforestation, mining, agriculture, urban expansion and hydro-electric projects.

  • What are Smog Towers?

    Some researchers in New Delhi have observed paradoxical phenomena near the smog towers. The air closest to the tower should be cleanest, but the device recorded the opposite in several instances.

    What are Smog Towers?

    • Smog towers are structures designed to work as large-scale air purifiers. They are fitted with multiple layers of air filters and fans at the base to suck the air.
    • After the polluted air enters the smog tower, it is purified by multiple layers before being re-circulated into the atmosphere.

    Structure of the Delhi smog tower

    • The structure is 24 m high, about as much as an 8-storey building — an 18-metre concrete tower, topped by a 6-metre-high canopy. At its base are 40 fans, 10 on each side.
    • Each fan can discharge 25 cubic metres per second of air, adding up to 1,000 cubic metres per second for the tower as a whole. Inside the tower in two layers are 5,000 filters.
    • The filters and fans have been imported from the United States.

    How does it work?

    • The tower uses a ‘downdraft air cleaning system’ developed by the University of Minnesota.
    • Polluted air is sucked in at a height of 24 m, and filtered air is released at the bottom of the tower, at a height of about 10 m from the ground.
    • When the fans at the bottom of the tower operate, the negative pressure created sucks in air from the top.
    • The ‘macro’ layer in the filter traps particles of 10 microns and larger, while the ‘micro’ layer filters smaller particles of around 0.3 microns.
    • The downdraft method is different from the system used in China, where a tower uses an ‘updraft’ system — air is sucked in from near the ground, and is propelled upwards by heating and convection.
    • Filtered air is released at the top of the tower.

    Likely impact

    • Computational fluid dynamics modelling suggests the tower could have an impact on the air quality up to 1 km from the tower.
    • The actual impact will also determine how the tower functions under different weather conditions, and how levels of PM2.5 vary with the flow of air.

    Issues with smog towers

    • Many experts say that the smog towers are not a viable method to clean city’s air.
    • The government had talked about 80% pollution reduction at inlet and outlet of the tower but never mentioned about the effect of distance from the tower.
    • Instead of spending ₹40 crore on two towers, the government could have spent the funds on several other options such as replacing the small and polluting industrial boilers or chimneys etc.
