  • Issues with the Environmental Performance Index (EPI)

    Context

    The 2022 Environmental Performance Index (EPI) produced by Yale and Columbia Universities and released on World Environment Day (June 5) has triggered much consternation in India, as the country is ranked last (180th).

    Issues with EPI 2022

    • Ignoring the past effects: Indicators may focus on current rates of increase or decrease in environmental pressures (flows) — as the EPI does for carbon dioxide emissions and tree cover gains — but under-state the accumulated effect (stocks) that relates to actual harm, thereby ignoring past effects.
    • Same standard in different socio-ecological context: When ranking countries, one is essentially applying the same standard across vastly different socio-ecological contexts – this involves difficult choices.
    • For example, the EPI leaves out arsenic in water, which is a major threat in Bangladesh.
    • Difficulty in measurement of frogress on climate change: Climate change is a global environmental problem, and because its effects depend on the accumulation of greenhouse gases over time, measuring progress in a given country is challenging.
    • Climate change mitigation has to be measured against what it is reasonable and fair to expect from different countries, taking into account their past emissions as well as national contexts.
    • There has been an inconclusive 30-year debate on this question; any choice of benchmark involves major ethical choices.
    • EPI has given 38 per cent weight to the climate change in the index.
    • They assume that the world must reach net zero emissions by 2050, and so the appropriate benchmark is whether all countries are reducing emissions and reaching zero by 2050.
    • Against CBDR: This approach is contrary to widely accepted ethical principles, especially the global political agreement on common-but-differentiated-responsibility (CBDR).
    • The Yale-Columbia approach ignores the fact that countries have different responsibilities for past accumulations and are at different levels of emissions and energy use.
    • The inclusion of indicators on emissions intensity and emissions per capita partly addresses this issue, but these two account for 7 per cent of the weight, versus 89 per cent for indicators derived from current emission trends.

    Implications EPI’s approach

    • This approach is guaranteed to make richer countries look good, because they have accumulated emissions in the past, but these have started declining in the last decade.
    •  Meanwhile, poorer countries that have emitted comparatively little in the past, look bad.
    • The EPI’s flawed and biased approach distracts from a much-needed honest conversation about the environment in India.
    • India’s local environmental performance on air, water and forests is deeply problematic.
    • Air quality in India is now the second largest risk factor for public health in India, behind only child and maternal nutrition.
    • Rivers and lakes are increasingly polluted, rivers are drying, groundwater tables are rapidly declining, and gains in tree cover hide declining natural productivity and diversity of forests and grasslands.

    Conclusion

    While indices like these have a limited attention-grabbing purpose, they serve this purpose well only when they are focused, limited to easy-to-measure metrics, and consciously minimise value judgements. The EPI 2022 resoundingly fails this test.

  • Microplastics found in Antarctica

    Scientists have found microplastics — plastic pieces much smaller than a grain of rice — in freshly fallen Antarctic snow for the first time.

    What are Microplastics?

    • Microplastics are tiny bits of various types of plastic found in the environment.
    • The name is used to differentiate them from “macroplastics” such as bottles and bags made of plastic.
    • There is no universal agreement on the size of microplastics. It defines microplastic as less than 5mm in length.
    • However, for the purposes of this study, since the authors were interested in measuring the quantities of plastic that can cross the membranes and diffuse into the body via the bloodstream.
    • Hence they agreed on an upper limit on the size of the particles as 0.0007 millimetre.

    Why in news?

    • Researchers have found microplastics in the snow samples from the Ross Ice Shelf in Antarctica.

    Threats posed by Microplastics

    • Microplastics has the potential to influence the climate by accelerating melting of ice.
    • They limit growth, reproduction, and general biological functions in organisms, as well as humans.

    Back2Basics: Ross Ice Shelf

    • Ross Ice Shelf is the largest ice shelf of Antarctica roughly the size of France.
    • It is several hundred metres thick.
    • The nearly vertical ice front to the open sea is more than 600 kilometres long, and between 15 and 50 metres (50 and 160 ft) high above the water surface.
    • Ninety percent of the floating ice, however, is below the water surface.
    • Most of Ross Ice Shelf is in the Ross Dependency claimed by New Zealand.
    • It floats in, and covers, a large southern portion of the Ross Sea and the entire Roosevelt Island located in the east of the Ross Sea.

  • Tendu Leaves Collection in India

    Tribal residents in Chhattisgarh have decided to file an FIR against an official of the state forest department after he confiscated the tendu leaves that they had collected.

    Tendu Leaves

    • Leaves of tree species Diospyros melanoxyion are used as wrappers of tobacco to produce bidi.
    • This tree is commonly known as “tendu,” but also called “abnus” in Andhra Pradesh, “kendu” in Orissa and West Bengal, “tembru” in Gujarat, “kari” in Kerala, “tembhurni” in Maharahstra, and “bali tupra” in Tamil Nadu.
    • This leaf is considered the most suitable wrapper on account of the ease with which it can be rolled and its wide availability.
    • Tendu is also called ‘green gold’ and is a prominent minor forest produce in India.

    How it is traded?

    • In 1964, the trade in tendu leaves was nationalised in then-undivided Madhya Pradesh.
    • Until then, people were free to sell tendu leaves in markets across the country.
    • Maharashtra adopted the same system in 1969, undivided Andhra Pradesh in 1971, Odisha in 1973, Gujarat in 1979, Rajasthan in 1974 and Chhattisgarh in 2000.
    • Under this arrangement, the state forest department collects tendu leaves, allows their transportation and sells them to traders.

    Why is there a dispute?

    • The dispute is essentially about who has the right to sell the leaves.
    • State governments say only they can do so due to nationalization.
    • On the other hand, tendu leaf collectors cite The Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006 and the 2013 Supreme Court verdict in the Niyamgiri Case to say private collectors can sell them on their own.
    • Tendu leaf collectors allege that the government gives them a lower price for the leaves, while it fetches a higher price in the open market.

    What do the tribals want?

    • The tribals, after having obtained forest rights leases under the FRA 2006, now want to sell tendu leaves on their own, with the permission of Gram Sabhas and make good profits.
    • Many types of minor forest produce like Mahua, Salbeej or the seeds of the Sal tree (Shorea robusta) and Chironji or Almondette kernels (Buchanania lanzan) are collected and sold by tribals.
    • Hence, there should not be a dispute over tendu leaves.

    Back2Basics: Forest Produce in India

    • Forest produce is defined under section 2(4) of the Indian Forest Act, 1927.
    • Its legal definition includes timber, charcoal, catechu, wood-oil, resin, natural varnish, bark, lac, mahua flowers, trees and leaves, flowers and fruit, plants (including grass, creepers, reeds and moss), wild animals, skins, tusks, horns, bones, cocoons, silk, honey, wax, etc.
    • Forest produce can be divided into several categories.
    • From the point of view of usage, forest produce can be categorized into three types: Timber, Non-Timber and Minor Minerals.
    • Non-timber forest products (NTFPs) are known also as minor forest produce (MFP) or non-wood forest produces (NWFP).
    • The NTFP can be further categorized into medicinal and aromatic plants (MAP), oilseeds, fibre & floss, resins, edible plants, bamboo, reeds and grasses

  • Rhino reintroduction a hit in Assam Reserves

    The one-horned rhinos of western Assam’s Manas National Park, bordering Bhutan, are expected to have high life expectancy and significant growth in population, the 14th Assam rhino estimation census has revealed.

    Indian Rhino

    • The Indian rhinoceros also called the greater one-horned rhinoceros and great Indian rhinoceros is a rhinoceros native to the Indian subcontinent.
    • It is listed as Vulnerable on the IUCN Red List and Schedule I animal in the Wildlife Protection Act, 1972.
    • It once ranged across the entire northern part of the Indian Subcontinent, along the Indus, Ganges and Brahmaputra River basins, from Pakistan to the Indian-Myanmar border.
    • Poaching for rhinoceros horn became the single most important reason for the decline of the Indian rhino.

    Why in news?

    • The 14th Rhino Population Estimation / Census in Kaziranga National Park counted at least 2613 rhinos including calves, a jump of exactly 200 rhinos since the last census conducted in 2018.
    • Then at least 2413 Rhinos were counted in the national park.

    Threats to Rhinos

    • Ground rhino horn is used in traditional Chinese medicine to cure a range of ailments, from cancer to hangovers, and also as an aphrodisiac.
    • In Vietnam, possessing a rhino horn is considered a status symbol.
    • Due to demand in these countries, poaching pressure on rhinos is ever persistent against which one cannot let the guard down.

    Various protection moves

    • A rhino reintroduction programme under the Indian Rhino Vision 2020 was started in 2006.
    • This entailed the translocation of rhinos from Kaziranga National Park and Pobitora Wildlife Sanctuary besides orphans hand-reared at the Centre for Wildlife Rehabilitation and Conservation at Kaziranga.

  • What are ‘Green Jobs’, mentioned by PM in his Environment Day speech?

    At an event to mark World Environment Day recently, PM mentioned India’s efforts to create ‘green jobs’.

    What are ‘Green Jobs’?

    • ‘Green jobs’ refer to a class of jobs that directly have a positive impact on the planet, and contribute to the overall environmental welfare.
    • Jobs involving renewable energy, conservation of resources, ensuring energy efficient means are categorised under the same.
    • In all, they are aimed at reducing the negative environmental impact of economic sectors and furthering the process of creating a low-carbon economy.
    • The idea behind a low-carbon economy or decarbonisation is fairly simple — it is about maintaining a sustainable economy.

    India and ‘green jobs’

    • The Skill Council for Green Jobs was launched by the Union government on October 1, 2015.
    • Aligned to the National Skill Development Missions, it was set up to be a not-for-profit, independent, industry-led initiative.

    Why need Green Jobs?

    • The UNEP’s 2019 Emissions Gap report dictates that it is essential for greenhouse gas emissions to reduce by 7.6% per annum between the years 2020 to 2030.
    • This is necessary to reach the target that was set during the Paris Agreement.
    • Failing to meet the same would consequently result in a failure to effectively combat global warming.
    • Consequently, a decarbonized economy plays a key role in ensuring a greener, safer, healthier and more sustainable planet to inhabit.

    Way forward

    • According to the ILO, India moving to a green economy by the next decade would alone create about 3 million jobs in the renewable energy sector.
    • The renewable energy sector created about 47,000 new jobs in 2017 accounting for a 12% increase in just the span of a year.
    • For India ‘green jobs’ can prove immensely useful to the country with sectors like renewable energy, waste management, green transport and urban farming.
    • An integrated, systematic approach is crucial to ensuring this.

  • World’s first Fishing Cat Census done in Chilika

    The Chilika Lake, Asia’s largest brackish water lagoon, has 176 fishing cats, according to a census done by the Chilika Development Authority (CDA) in collaboration with the Fishing Cat Project (TFCP).

    About Fishing Cats

    • About twice the size of a typical house cat, the fishing cat is a feline with a powerful build and stocky legs.
    • It is an adept swimmer and enters water frequently to prey on fish as its name suggests.
    • It is known to even dive to catch fish.
    • It is nocturnal and apart from fish also preys on frogs, crustaceans, snakes, birds, and scavenges on carcasses of larger animals.
    • It is capable of breeding all year round but in India its peak breeding season is known to be between March and May.

    Conservation status

    • IUCN Red List: Endangered
    • CITES: Appendix II
    • Indian Wildlife (Protection) Act, 1972: Schedule I

    Various threats

    • One of the major threats facing the fishing cat is the destruction of wetlands, which is its preferred habitat.
    • As a result of human settlement, drainage for agriculture, pollution, and wood-cutting most of the wetlands in India are under threat of destruction.
    • Another threat to the fishing cat is the depletion of its main prey-fish due to unsustainable fishing practices.
    • It is also occasionally poached for its skin.

    Back2Basics: Chilika Lake

    • Chilika Lake is a brackish water lagoon, spread over the Puri, Khurda and Ganjam districts of Odisha.
    • It is located at the mouth of the Daya River, flowing into the Bay of Bengal, covering an area of over 1,100 km2.
    • It is the largest coastal lagoon in India and the largest brackish water lagoon in the world after The New Caledonian barrier reef.
    • It has been listed Ramsar Site as well as a tentative UNESCO World Heritage site.

    Its formation

    • The process of the formation of the Chilika might have begun in the latter part of the Pleistocene epoch, around 20,000 years ago.
    • India’s peninsular river Mahanadi carried a heavy load of silt and dumped part of it at its delta.
    • As the sediment-laden river met the Bay of Bengal, sand bars were formed near its mouth.
    • These created a backflow of the seawater into the sluggish fresh water at the estuary, resulting in the huge brackish water lake.
    • Marine archaeological studies on the Odisha coast clearly show that the Chilika once acted as a safe harbor for cargo ships bound for Southeast Asia and other parts of the world.

  • E-Waste Recycling in India

    Attero Recycling, one of India’s largest electronic waste management companies, is set to invest close to $1 billion in expanding their electronic waste recycling facilities in India.

    E-waste Management: A tricky task

    • E-waste management is a complicated process given the multitude of actors that are involved in the process.
    • The major stakeholders in the value chain include importers, producers/manufacturers, retailers (businesses/government/others), consumers (individual households, businesses, government and others), traders, scrap dealers, dissemblers/dismantlers and recyclers.
    • To critically assess each in the different stages of processing, it is important to understand the e-waste value chain.
    • The process involves four stages: generation, collection, segregation and treatment/disposal.

    India’s regulatory ecosystem

    • Indian electronics sector boomed in the last decade.
    • Increased production and penetration of imported electronics items led to an accelerated e-waste generation that necessitated regulatory control over the sector.
    • India has Electronic Waste (Management and Handling) Rules 2011 in place since . Its scope was expanded in 2016 and 2018 through amendments.

    Provisions of the 2011 Rules

    • To streamline e-waste management, the Government introduced Extended Producer Responsibility (EPR) whereby producers were required to collect and recycle electronic items.
    • Since manufacturers were incurring the disposal cost, their designs would incorporate less toxic and easily recyclable materials, thereby reducing input material requirements.

    Inherent flaws in Implementation

    • Recycling: Less than five percent of the waste is treated through formal recycling facilities.
    • Informal sector: The rest is handled by the informal sector with very little enforcement of environmental and occupational safety norms.
    • Weak Regulations: A deeper analysis revealed that the EPR regulations in India were not quantified through collection or recycling targets as in other countries with better implementation framework and mechanisms.
    • Lack of incentivization: In the absence of targets, producers had little incentive to ensure the collection of their used products.

    Current scenario and issues in e-waste recycling

    • Crude and Scrappage: As of today, some 95% of e-waste is managed by the informal sector which operates under inferior working conditions and relies on crude techniques for dismantling and recycling.
    • Infrastructure lacunae: Another important issue is the lack of sufficient metal processing infrastructure which is why recyclers have to export materials to global smelters.
    • Price competencies: As aggregators are mostly informal, they demand up-front cash payments.
    • Bloomed informal network: The informal network is well-established and rests on social capital ties that PROs have yet to establish and are hence insulated from reaching the viable number of aggregators.
    • Policy failure: Policy changes have tried repeatedly to formalize the sector, but issues of implementation persist on the ground.

    Way forward

    • Effective design: Since India is highly deficient in precious mineral resources, there is a need for a well-designed, robust and regulated e-waste recovery regime that would generate jobs and wealth.
    • Consumer responsibility: The consumers must responsibly consume the product for its useful life and then weigh between the chances of repair or disposal with utmost consciousness towards the environment.
    • Recyclable products: On the supply side, e-waste can be reduced when producers design electronic products that are safer, and more durable, repairable and recyclable.
    • Reuse: Manufacturers must reuse the recyclable materials and not mine rare elements unnecessarily to meet new production.
    • Commercial recycling: Rather than hoping that informal recyclers become formal it would be more feasible for companies and the state to design programs ensure e-waste easily makes its way to proper recyclers.

  • Keep ESZ of 1 Km around Forests: SC

    The Supreme Court has directed that every protected forest, national park and wildlife sanctuary across the country should have a mandatory eco-sensitive zone (ESZ) of a minimum one km starting from their demarcated boundaries.

    Why such move?

    • The purpose of declaring ESZs around national parks, forests and sanctuaries is to create some kind of a “shock absorber” for the protected areas.
    • These zones would act as a transition zone from areas of high protection to those involving lesser protection.

    What are the Eco-sensitive Zones (ESZs)?

    • Eco-Sensitive Zones (ESZs) or Ecologically Fragile Areas (EFAs) are areas notified by the MoEFCC around Protected Areas, National Parks and Wildlife Sanctuaries.
    • The purpose of declaring ESZs is to create some kind of “shock absorbers” to the protected areas by regulating and managing the activities around such areas.
    • They also act as a transition zone from areas of high protection to areas involving lesser protection.

    How are they demarcated?

    • The Environment (Protection) Act, 1986 does not mention the word “Eco-Sensitive Zones”.
    • However, Section 3(2)(v) of the Act, says that Central Government can restrict areas in which any industries, operations or processes or class of industries, operations or processes shall be carried out or shall not, subject to certain safeguards.
    • Besides Rule 5(1) of the Environment (Protection) Rules, 1986 states that central government can prohibit or restrict the location of industries and carrying on certain operations or processes on the basis of certain considerations.
    • The same criteria have been used by the government to declare No Development Zones (NDZs).

    Defining its boundaries

    • An ESZ could go up to 10 kilometres around a protected area as provided in the Wildlife Conservation Strategy, 2002.
    • Moreover, in the case where sensitive corridors, connectivity and ecologically important patches, crucial for landscape linkage, are beyond 10 km width, these should be included in the ESZs.
    • Further, even in the context of a particular Protected Area, the distribution of an area of ESZ and the extent of regulation may not be uniform all around and it could be of variable width and extent.

  • Posidonia Australis: World’s Largest Plant

    The world’s largest plant has recently been discovered off the West Coast of Australia: a seagrass 180 km in length.

    Posidonia australis

    • The ribbon weed, or Posidonia australis, has been discovered in Shark Bay by a group of researchers from Flinders University and The University of Western Australia.
    • These researchers have also found that the plant is 4,500 years old, is sterile, has double the number of chromosomes than other similar plants.
    • It has managed to survive the volatile atmosphere of the shallow Shark Bay.

    So how remarkable is this plant’s size?

    • The ribbon weed covers an area of 20,000 hectares.
    • The next on the podium, the second largest plant, is the clonal colony of a quaking Aspen tree in Utah, which covers 43.6 hectares.
    • The largest tree in India, the Great Banyan in Howrah’s Botanical Garden, covers 1.41 hectares.

    If it is so large, how come it has just been discovered?

    • The existence of the seagrass was known, that it is one single plant was not.
    • Researchers were interested in what they then thought was a meadow because they wanted to study its genetic diversity, and collect some parts for seagrass restoration.

    How did it grow, and survive for, so long?

    • Sometime in the Harappan era, a plant took root in the Shark Bay.
    • Then it kept spreading through its rhizomes, overcoming everything in its way, and here we are today.
    • Ribbon weed rhizomes can usually grow to around 35cm per year, which is how the scientists arrived at its lifespan of 4,5000 years.
    • The researchers found that the ribbon weed cannot spread its seeds, something that helps plants overcome environmental threats.
    • Also, Shark Bay sees fluctuations in temperature and salinity and gets a lot of light, conditions challenging for any plant.

    Ecological significance

    • Because seagrass performs a vital role in the environment, and if some of it is hardy, it is good news for everyone in a world threatened by climate change.
    • In India, seagrass is found in many coastal areas, most notably in Gulf of Mannar and Palk Strait.
    • Apart from being home to a variety of small organisms, seagrass trap sediments and prevent water from getting muddy, absorb carbon from the atmosphere, and prevent coastal erosion.
