  • Air Quality Commission Bill, 2021

    The Lok Sabha has passed the Bill to formalize the Commission for Air Quality Management For National Capital Region and Adjoining Areas.

    Highlights of the AQC Bill

    • The AQC would be a ‘permanent’ body to address pollution in the National Capital Region Delhi and address sources of pollution in Delhi, Punjab, Rajasthan, Haryana and Uttar Pradesh.
    • The all-powerful body assumed several powers to coordinate action among States, levy fines — ranging up to ₹1 crore or five years of prison — to address air pollution.

    Key features

    • Over-riding powers: While the Central Pollution Control Board (CPCB) and its state branches have the powers to implement provisions of the Environment Protection Act for air, water and land pollution.
    • In case of dispute or a clash of jurisdictions, the AQC’s writ would prevail specific to matters concerning air pollution.
    • Chair: The body has a full-time chairperson and a range of members consisting of both representatives from several Ministries as well as independent experts and will have the final say on evolving policy and issuing directions.
    • Curb on stubble burning: the Commission may impose and collect environment compensation causing pollution by stubble burning.
    • No penalties to farmers: The Centre, facing flak earlier this year from farmers protesting the farm laws, had committed to removing a clause in the Air Commission Bill that would penalize farmers for burning stubble, an important contributor to noxious air quality.

  • [pib] 14 Indian Tiger Reserves get Global CA/TS recognition

    The Environment Ministry has released the names of the 14 tiger reserves that had received the accreditation of the Global Conservation Assured|Tiger Standards (CA|TS), an accreditation tool agreed upon by tiger range countries.

    Conservation Assured | Tiger Standards (CA|TS)

    • CA|TS has been agreed upon as an accreditation tool by the global coalition of Tiger Range Countries (TRCs) and has been developed by tiger and protected area experts.
    • Officially launched in 2013, it sets minimum standards for effective management of target species and encourages the assessment of these standards in relevant conservation areas.
    • CA|TS is a set of criteria that allows tiger sites to check if their management will lead to successful tiger conservation.
    • The Global Tiger Forum (GTF), an international NGO working on tiger conservation, and World Wildlife Fund India are the two implementing partners of the National Tiger Conservation Authority for CATS assessment in India.

    Which are the 14 reserves?

    The 14 tiger reserves which have been accredited are:

    • Manas, Kaziranga and Orang in Assam,
    • Satpura, Kanha and Panna in Madhya Pradesh,
    • Pench in Maharashtra,
    • Valmiki Tiger Reserve in Bihar,
    • Dudhwa in Uttar Pradesh,
    • Sunderbans in West Bengal,
    • Parambikulam in Kerala,
    • Bandipur Tiger Reserve of Karnataka and
    • Mudumalai and Anamalai Tiger Reserve in Tamil Nadu

    Significance

    • CATS accreditation is a global recognition of good tiger governance.
    • This recognition means a lot in the context of adaptation to climate change, sustainability of ecosystem services, and safeguarding disruption of zoonotic cycles, through an umbrella species approach.
    • The aspects monitored for accreditation include the importance and status of a reserve, management, community participation, tourism, protection, habitat management, and tiger populations.

    (b) Ranthambore

    (c) Nagarjunasagar-Srisailam

    (d) Sundarbans

  • Thane Creek Flamingo Sanctuary proposed as Ramsar Site

    The Mumbai Metropolitan Region is likely to get its first Ramsar site at the Thane Creek Flamingo Sanctuary.

    Thane Creek Flamingo Sanctuary

    • The Maharashtra Government has declared the area along the western bank of Thane Creek as the “Thane Creek Flamingo Sanctuary” since 2015.
    • It is Maharashtra’s second marine sanctuary after the Malvan sanctuary.
    • It is recognized as an “Important Bird Area” by the Bombay Natural History Society.

    About Ramsar Convention

    • The Convention on Wetlands of International Importance (better known as the Ramsar Convention) is an international agreement promoting the conservation and wise use of wetlands.
    • It is the only global treaty to focus on a single ecosystem.
    • The convention was adopted in the Iranian city of Ramsar in 1971 and came into force in 1975.
    • Traditionally viewed as a wasteland or breeding ground of disease, wetlands actually provide fresh water and food and serve as nature’s shock absorber.
    • Wetlands, critical for biodiversity, are disappearing rapidly, with recent estimates showing that 64% or more of the world’s wetlands have vanished since 1900.
    • Major changes in land use for agriculture and grazing, water diversion for dams and canals, and infrastructure development are considered to be some of the main causes of loss and degradation of wetlands.

    What does one mean by Ramsar Site?

    • A Ramsar Site is a wetland area designated to be of international importance under the Ramsar Convention.
    • It provides the framework for national action and international cooperation for the conservation and wise use of wetlands and their resources.

  • What is Gross Environment Product?

    The Uttarakhand government recently announced it will initiate valuation of its natural resources in the form of ‘Gross Environment Product’ (GEP), said to be along the lines of Gross Domestic Product (GDP).

    Why such a move?

    • The idea of the valuation of the components of the environment is not new.
    • But it got impetus following rapid degradation of ecosystems, which led to adverse impacts on more than 60 percent of services we get from the ecosystems.

    What is Gross Environment Product (GEP)?

    • GEP is the measure of ecosystem services of any area.
    • It reflects the aggregated annual value of goods and services provided by ecosystems (forests, water bodies, oceans, etc.) to people in a given region, such as at district levels, state, and country.
    • It entails the establishment of a natural capital accounting framework by integrating ecological benefits into common measures of economic growth such as GDP.
    • It summarizes the value of ecosystem services in a single monetary metric.

    Evolution of GEP

    • The term “ecosystem services” was coined in 1981 to attract academics towards this aspect.
    • Ecosystem services represent the benefits humans get: Forests, lakes, and grasslands; timber and dyed; carbon sequestration and nutrient cycling; soil formation and productivity; and tourism.
    • The definition is still in the process of evolution. The concept received attention and now is part of global knowledge.

    Advantages offered

    • GEP can be applied as a scientific basis for Eco-Compensation and public financial transfers.
    • For example, Finance Commission’s revenue-sharing formula between the Union and the states including forest cover as a determining factor in a state’s share.
    • GEP can be applied to measure the status of ecosystem services, which is an important indicator of sustainable development.
    • It is also a critical indicator for measuring the progress of Eco-civilization.
    • Its implementation can help assess the impact of anthropological pressure on our ecosystem and natural resources- air, water, soil, forests.

    The Himalayan context

    • The Himalayas contribute substantially to the sustainability of the Gangetic Plains where 500 million people live.
    • The Union government incorporated the value of ecosystem services of its states in national accounting.
    • According to the recommendation of the 12th and 13th Finance Commissions, grants were transferred to forest-rich states in amounts corresponding to their forest covers.
    • However, considering only the forest cover in transferring funds to states is inadequate.

  • Species in news: Great Indian Bustards

    The Environment Ministry has informed the Parliament that there were no Great Indian Bustards (GIB) left in Kutch Bustard Sanctuary (KBS) in Gujarat’s Kutch district.

    Great Indian Bustards

    • GIBs are the largest among the four bustard species found in India, the other three being MacQueen’s bustard, lesser florican, and the Bengal florican.
    • GIBs’ historic range included much of the Indian sub-continent but it has now shrunken to just 10 percent of it. Among the heaviest birds with flight, GIBs prefer grasslands as their habitats.
    • GIBs are considered the flagship bird species of grassland.

    On the brink of extinction

    • The GIB population in India had fallen to just 150.
    • Pakistan is also believed to host a few GIBs and yet openly supports their hunting.

    Protection accorded

    • Birdlife International: uplisted from Endangered to Critically Endangered (2011)
    • Protection under CITES: Appendix I
    • IUCN status: Critically Endangered
    • Protection under Wildlife (Protection) Act: Schedule I

    Threats

    • Overhead power transmission
    • Poor vision: Due to their poor frontal vision, can’t detect powerlines in time and their weight makes in-flight quick maneuvers difficult.
    • Windmills: Coincidentally, Kutch and Thar desert are the places that have witnessed the creation of huge renewable energy infrastructure.
    • Noise pollution: Noise affects the mating and courtship practices of the GIB.
    • Changes in the landscape: by way of farmers cultivating their land, which otherwise used to remain fallow due to frequent droughts in Kutch.
    • Cultivation changes: Cultivation of cotton and wheat instead of pulses and fodder are also cited as reasons for falling GIB numbers.

    Supreme Court’s intervention

    • The Supreme Court has ordered that all overhead power transmission lines in core and potential GIB habitats in Rajasthan and Gujarat should be undergrounded.
    • The SC also formed a three-member committee to help power companies comply with the order.

    Conservation measures

    • In 2015, the Central government launched the GIB species recovery program.
    • Under the program, the WII and Rajasthan Forest departments have jointly set up conservation breeding centers where GIB eggs are harvested from the wild.
    • They have been incubated artificially and hatchlings raised in a controlled environment.

  • Microplastics Pollution in Ganga

     

    The Ganga is heavily polluted with microplastics at Varanasi, Haridwar, and Kanpur, Delhi-based non-profit Toxics Link claimed.

    What are Microplastics?

    • Microplastics are plastics that are less than 5 mm in size but are a major source of marine pollution.
    • Untreated sewage from many cities along the river’s course, industrial waste, and religious offerings wrapped in non-degradable plastics pile pollutants into the river as it flows through several densely populated cities.
    • The plastic products and waste materials released or dumped in the river break down and are eventually broken down into microparticles.
    • The rivers finally transport significantly large quantities downstream into the ocean, which is the ultimate sink of all plastics being used by humans.

    Microplastics in Ganga

    • They are non-degradable plastics that often entered the Ganga through industrial waste or packaging of religious offerings, its research found.
    • The density of population in the three cities also added to the problem because a large chunk of pollutants got directly discharged into the river by people living on the banks.
    • Among the three cities, the Toxics Link’s study found that sites at Varanasi showed the maximum load of microplastics in the water of the Ganga, as compared to the other two cities.
    • This might be due to cumulative downstream pollution as well as industrial and human activities.

    On a global high

    • The researchers tried to compare the microplastics concentration in Ganga water with similar studies on other rivers across the globe.
    • It included the Rhine in Europe, the Patapsco, Magothy, Rhode in North America, and the Elqui, Maipo, Biobio, and Maule in South America.
    • They found the Ganga microplastics pollution was much higher.
    • This was in spite of a higher per capita consumption of plastic in the European countries, North and South America, as compared to India.

    How does it impact people?

    • The Ganga is a source of water for not just drinking and bathing purposes but also for irrigation to a large extent.
    • Microplastics in river water, if ingested in humans or other organisms, can cause toxicity through various means.
    • Not only are these microplastics toxic themselves, they also have a tendency to absorb various toxins present in water, including harmful chemicals.
    • Although some of the effects of microplastics on public health are understood, a lot still needs to be done.

    Q. Why is there a great concern about the ‘microbeads’ that are released into the environment? (CSP 2019)

    (a) They are considered harmful to marine ecosystems.

    (b) They are considered to cause skin cancer in children.

    (c) They are small enough to be absorbed by crop plants in irrigated fields.

    (d) They are often found to be used as food adulterants.

  • Why rooftop solar and storage offers a viable future for India

    The Union government’s target of producing 40 gigawatts of rooftop solar power by 2022 is unrealistic: The country could produce only 4.4 GW rooftop solar energy till March 31, 2021, according to the Union Ministry of New and Renewable Energy.

    What is Solar Rooftop?

    • A solar photovoltaic (PV) system mounted on a rooftop of a building is a mini-power requirement or feed into the grid.
    • The size of the installation varies significantly depending on the availability of space, amount of electricity consumed by the property and the ability or willingness of the owner to invest the capital required.

    Why rooftop?

    • Rooftop solar with a storage system is a benefit for both, end consumers as well as discoms (power distribution companies).
    • A one-kilowatt (kW) rooftop system can produce three to five units of electricity a day.
    • The combination increasingly becomes cost-effective for electricity generation compared to the traditional grid supply and diesel generators.
    • In 2021, solar and storage will be cheaper than grid supply for most commercial and industrial (C&I) customers.
    • The increase in penetration of rooftop solar in the distribution grid will have a significant impact on the stability of the grid.

    A viable alternative

    • Most housing societies in urban India rely on diesel generators for power backup. However, as power availability improves in the country, diesel generators will become redundant.
    • The operational cost of diesel generators is quite high— R16-18 per unit against Rs 5-6 a unit for solar rooftop systems. So rooftop solar power makes financial sense.Solar rooftop is also a perfect solution for commercial and institutional buildings that operate mostly during the day.
    • Their rooftops can be utilized to generate electricity, and they can, partially or completely, replace diesel generators. This would also help them reduce their electricity bills.

    Question of energy storage

    • In order to integrate rooftop solar and electric vehicles, the grid needs to be flexible and smart.
    • Energy storage systems will play a key role in providing this flexibility by acting as a load when there is a surplus generation, as well as generating sources when there is a supply shortage.
    • There are two major methods of integrating battery storage into the electric grid:
    1. Front-of-the-meter (FTM): It is implemented at the utility-scale, wherein the battery system is connected to the transmission or distribution network that ensures grid reliability. This happens on a considerably large scale (~MWh scale).
    2. Behind-the-meter (BTM): The other method is implemented at the residential and commercial/industrial level, mainly to provide backup during a power failure or to store excess locally generated energy from solar rooftop photovoltaic (PV) systems.

    India’s storage capacity

    • About 34 GW / 136 GWh of battery storage is expected to be installed by 2030, according to the Central Electricity Authority of India.
    • This capacity would be used for RE integration, demand-side and peak load management services.

    Storage challenges

    • The solar segment offers a huge market opportunity for advanced battery technologies.
    • However, manufacturers have some ground to cover in addressing technical limitations of batteries, such as charging characteristics, thermal performance and requirement of boost current to charge deep cycle batteries.
    • Since solar companies may directly procure batteries from manufacturers and require after-sale services and technical support, battery companies should have wider a presence to address these expectations.

    Other key challenges

    • Rooftop solar source doesn’t match the rise in renewable energy in India.
    • While industrial and commercial consumers account for 70% of total installed capacity residential consumers remain a big untapped potential to give the boost
    • Solar rooftops also face several challenges such as little consumer awareness, lack of innovative government policies or attention, bureaucratic hassles, and limited support from discoms.

    Way forward

    • Supportive policies and innovative technological approaches are needed for the sector to achieve its potential.
    • Indian policymakers need to plan for rooftop solar plus storage, rather than rooftop solar alone with the grid as storage (net / gross metering).
    • The declining cost of storage solutions, along with that of rooftop solar solutions, is likely to change the future of the Indian power sector.
    • Several countries such as Australia, the United States, Germany, among others have already endorsed solar power with battery storage.
    • Energy storage, therefore, represents a huge economic opportunity for India.
    • The creation of a conducive battery manufacturing ecosystem on a fast track could cement India’s opportunity for radical economic and industrial transformation in a critical and fast-growing global market.

  • Re-wilding of wild animals and the challenges involved

    The recent attempt of Periyar Tiger Reserve (PTR) to reintroduce into the wild tiger cub named Mangala after rearing it in ‘captivity’ has once again brought the controversial concept of ‘re-wilding’ of abandoned or injured animals under the lens.

    What is the intervention known as ‘re-wilding’?

    • As per the Standard Operating Procedures/Guidelines laid down by the National Tiger Conservation Authority (NTCA) under the Wildlife Protection Act, 1972, there are three ways to deal with orphaned or abandoned tiger cubs.
    1. The first is to make an effort to reunite the abandoned cubs with their mother.
    2. Second, if a reunion of the cub with its mother is not possible, then shift the cub to a suitable zoo.
    3. Third, reintroduction of the cub into the wild after a certain time when it appears that the cub is capable of surviving in the wild independently.
    • This is what is known as ‘re-wilding.

    NTCA guidelines

    • NTCA stresses that the tiger cub should be reared in an in situ enclosure for a minimum of two years, and during this time, each cub should have a successful record of at least 50 ‘kills’.
    • Within the enclosure, the persons responsible for handling cubs must approach them by putting a tiger mask along with workday clothes of a tiger stripe pattern smeared with tiger urine and faeces.
    • Various conditions must be complied with at the time of releasing the cub in the wild.
    • The tiger cubs should be in prime health, and of dispersing age (three/four years).
    • There should be no abnormality/incapacitation.

    How have attempts at re-wilding of carnivores gone in India?

    • The tiger conservationist Billy Arjan Singh was credited with the re-introduction of re-welding the Dudhwa forest area in the 1970s.
    • The attempt, however, ran into controversy after several incidents of the killing of humans were reported.
    • The re-wilding in Panna Tiger Reserve of two abandoned tigress cubs that were brought up at Kanha Tiger Reserve is considered to be a success in tiger conservation.

    Re-wilding as a concept

    • There are 50-50 chances of success and failure of re-wilding of hand-reared carnivores in the wild.
    • Conservationists, however, maintain that the chances of success are far less than that — less than even 1 per cent.
    • Tigers in India are already occurring at naturally attainable densities.
    • Almost all translocations of captive-raised tigers have failed so far, with only rare successes such as in Panna after a tiger extinction, and some re-introductions in Russia into empty habitats with plenty of prey.

    Way forward

    • The real need is to protect more habitat strictly so that the prey densities rise and more tigers can thrive.
    • Putting individual hand-reared tigers into the wild cannot certainly be called re-wilding says some wildlife activists.

  • Sikkim is home to 27% of India’s flowering plants

    Sikkim, the smallest State with less than 1% of India’s landmass, is home to 27% of all flowering plants found in the country, reveals a recent publication by the Botanical Survey of India (BSI).

    Flora of Sikkim

    • Flora of Sikkim – A Pictorial Guide lists 4,912 naturally occurring flowering plants in the tiny Himalayan State.
    • The total number of naturally occurring flowering plants in the country is about 18,004 species, and with 4,912 species, the diversity of flowering plants in Sikkim, spread over an area of 7,096 sq. km. is very unique.

    Why is Sikkim a host to such large biodiversity?

    • Sikkim is a part of the Kanchenjunga biosphere landscape, has different altitudinal ecosystems, which provide opportunities for herbs and trees to grow and thrive.
    • The State also borders China, Bhutan and Nepal, and the Darjeeling Hills of West Bengal.
    • From subalpine vegetation to the temperate to the tropical, the State has different kinds of vegetation, and that is the reason for such a diversity of flora.
    • The elevation also varies between 300 to 8,598 metres above mean sea level, the apex being the top of Mt. Kanchenjunga (8,586 metres).

    Contribution by the Public

    • The people of Sikkim have a unique bond with nature and trees.
    • As per the Sikkim Forest Tree (Amity & Reverence) Rules, 2017 the State government allows any person to associate with trees standing on his or her private land or on any public land by entering into a Mith/Mit or Mitini relationship.
    • The notification encouraged people to adopt a tree “as if it was his or her own child in which case the tree shall be called an adopted tree”.

  • Places in news: Lemru Elephant Reserve

    The proposed Lemru Elephant Reserve in Chhattisgarh, in the pipeline for 20 years, has become the subject of yet another controversy over the reduction of its size.

    Lemru Elephant Reserve

    • The proposal for the reserve, in Korba district, was passed unanimously by the Assembly in 2005 and got central approval in 2007.
    • Lemru is one of two elephant reserves planned to prevent human-animal conflict in the region, with elephants moving into Chhattisgarh from Odisha and Jharkhand.
    • Its area was then proposed to be 450 sq km.

    Why does the government want to reduce the size of the reserve?

    • The area proposed under the reserve is part of the Hasdeo Aranya forests, a very diverse biozone that is also rich in coal deposits.
    • Of 22 coal blocks in the area, seven have already been allotted with mines running in three, and in the process of being established in the other four.
    • Under the ‘No-Go Area’ policy from the UPA area, the entire area was considered out of bounds for mines, but in 2020, five coal blocks from the region were put on the auction list.

    Why is the reserve important?

    • North Chhattisgarh alone is home to over 240 elephants.
    • Elephants in Chhattisgarh are relatively new; they started moving into undivided Madhya Pradesh in 1990.
    • Since these animals were relatively new, the human-animal conflict started once elephants started straying into inhabited areas, looking for food.
