  • 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.

  • Environmental Performance Index (EPI), 2022

    India has objected to a report, called the EPI, 2022, that places the country last (along with Nigeria) on a list of 180 countries on managing climate change, environmental health, and ecosystem vitality.

    Environmental Performance Index

    • The report is prepared by researchers at the Yale and Columbia universities.
    • It provides a data-driven summary of the state of sustainability around the world.
    • Using 40 performance indicators across 11 issue categories, the EPI ranks 180 countries on climate change performance, environmental health, and ecosystem vitality.
    • These indicators provide a gauge at a national scale of how close countries are to established environmental policy targets.
    • The EPI offers a scorecard that highlights leaders and laggards in environmental performance and provides practical guidance for countries that aspire to move toward a sustainable future.

    Why the report is inherently biased?

    • The US placed itself at the 20th spot of the 22 wealthy democracies in the global west and 43rd overall.
    • The relatively low ranking has put all blame on the rollback policies during the Trump administration.
    • It goes on to preach that developing countries do not have to sacrifice sustainability for economic security.

  • 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.

  • Monsoon sets in over Kerala

    The monsoon has reached Kerala, the India Meteorological Department (IMD).

    What does the “Onset of Monsoon” mean?

    • The onset of the monsoon over Kerala marks the beginning of the four-month — June-September — southwest monsoon season over India.
    • It brings more than 70 per cent of the country’s annual rainfall. This marks a significant day in India’s economic calendar.
    • IMD announces it only after certain newly defined and measurable parameters, adopted in 2016, are met.
    • Broadly, the IMD checks for the consistency of rainfall over a defined geography, its intensity, and wind speed.

    (1) Rainfall

    • The IMD declares the onset of the monsoon if at least 60% of 14 designated meteorological stations in Kerala and Lakshadweep.
    • The 14 enlisted stations are: Minicoy, Amini, Thiruvananthapuram, Punalur, Kollam, Alappuzha, Kottayam, Kochi, Thrissur, Kozhikode, Thalassery, Kannur, Kasaragod, and Mangaluru.
    • It records at least 2.5 mm of rain for two consecutive days at any time after May 10.
    • In such a situation, the onset over Kerala is declared on the second day, provided specific wind and temperature criteria are also fulfilled.

    (2) Wind field

    • The depth of westerlies should be up to 600 hectopascal (1 hPa is equal to 1 millibar of pressure) in the area bound by the equator to 10ÂșN latitude, and from longitude 55ÂșE to 80ÂșE.
    • The zonal wind speed over the area bound by 5-10ÂșN latitude and 70-80ÂșE longitude should be of the order of 15-20 knots (28-37 kph) at 925 hPa.

    (3) Heat

    • According to IMD, the INSAT-derived Outgoing Longwave Radiation (OLR) value (a measure of the energy emitted to space by the Earth’s surface, oceans, and atmosphere) should be below 200 watt per sq m (wm2).
    • This is measured in the box confined by 5-10ÂșN latitude and 70-75ÂșE latitude.

    Is it unusual for the monsoon to hit the Kerala coast early?

    • Neither early nor late onset of the monsoon is unusual.
    • In 2018 and 2017, the onset over Kerala occurred on May 29 and May 30, respectively.
    • In 2010, onset was realised on May 31.
    • In 2020 and 2013, the monsoon was exactly on time, hitting the Kerala coast on June 1.

    Does an early onset foretell a good monsoon?

    • No, it does not — just as a delay does not foretell a poor monsoon.
    • The onset is just an event that happens during the progress of the monsoon over the Indian subcontinent.
    • A delay of a few days, or perhaps the monsoon arriving a few days early, has no bearing on the quality or amount of rainfall.

    How does the monsoon spread across the country after hitting Kerala coast?

    • The northward progression of the monsoon after it has hit the Kerala coast depends on a lot of local factors, including the creation of low pressure areas.
    • Though this year monsoon has arrived early, it is possible that despite a late onset over Kerala, other parts of the country start getting rain on time.
    • After its onset over Kerala, the monsoon spreads over the entire country by July 15.

  • What are Community Forest Rights?

    The Chhattisgarh government has become the only second state in the country to recognize the Community Forest Resource (CFR) rights of a village inside a national park.

    What is the news?

    • The CFR rights of tribals living in a hamlet inside the Kanger Ghati National Park in Bastar district, were recognised.
    • It gave the community the power to formulate rules for forest use.

    Try this PYQ first:

    Q.Under the Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006, who shall be the authority to initiate the process for determining the nature and extent of individual or community forest rights or both?

    (a) State Forest Department

    (b) District Collector/Deputy Commissioner

    (c) Tahsildar/Block Development Officer/Mandal Revenue Officer

    (d) Gram Sabha

     

     

    [wpdiscuz-feedback id=”wi5gjmhhdk” question=”Please leave a feedback on this” opened=”1″]Post your answers here.[/wpdiscuz-feedback]

    What is a Community Forest?

    • The community forest resource area is the common forest land that has been traditionally protected and conserved for sustainable use by a particular community.
    • The community uses it to access resources available within the traditional and customary boundary of the village; and for seasonal use of landscape in case of pastoralist communities.
    • Each CFR area has a customary boundary with identifiable landmarks recognised by the community and its neighboring villages.
    • It may include forest of any category – revenue forest, classified & unclassified forest, deemed forest, DLC land, reserve forest, protected forest, sanctuary and national parks etc.

    Legal basis for Community Forest Resource (CFR) rights

    • The CFR rights are acknowledged under the Section 3(1) (i) of the Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act.
    • This is commonly referred to as the Forest Rights Act or the FRA.
    • It aims to provide for recognition of the right to “protect, regenerate or conserve or manage” the community forest resource.
    • These rights allow the community to formulate rules for forest use by itself and others and thereby discharge its responsibilities under Section 5 of the FRA.

    Nature of rights included

    • CFR rights, along with Community Rights (CRs) under Sections 3(1)(b) and 3(1)(c), which include: nistar rights and rights over non-timber forest products, ensure sustainable livelihoods of the community.
    • ‘Nistar’ means the concession granted for removal from forest coupes (small trees) on payment at stipulated rates, specified forest produce for bonafide domestic use, but not for barter or sale.
    • These rights give the authority to the Gram Sabha to adopt local traditional practices of forest conservation and management within the community forest resource boundary.

    Why is the recognition of CFR rights important?

    • Aimed at undoing the “historic injustice” meted out to forest-dependent communities due to curtailment of their customary rights over forests, the FRA came into force in 2008.
    • It is important as it recognises the community’s right to use, manage and conserve forest resources, and to legally hold forest land that these communities have used for cultivation and residence.
    • It also underlines the integral role that forest dwellers play in the sustainability of forests and in the conservation of biodiversity.
    • It is of greater significance inside protected forests like national parks, sanctuaries and tiger reserves as traditional dwellers then become a part of management of the protected forests.

    How many CFR certificates have been given in Chhattisgarh?

    • According to state government officials, Chhattisgarh has recognised nearly 4,000 CFR rights in the state.
    • Kanger Ghati National Park is the second national park, after Simlipal in Odisha, where CFR rights have been recognised.
