  • Taproots to help restore India’s fading green cover

    This op-ed tries to establish a fair link between forest cover and population dependency on it.

    A decline in Forest Cover

    • The State of the World’s Forests report 2020, says that since 1990, around 420 million hectares of forest have been lost through deforestation, conversion and land degradation.
    • Nearly 178 million hectares have decreased globally due to deforestation (1990-2020).
    • India lost 4.69 MHA of its forests for various land uses between 1951 to 1995.

    Various reasons

    • Despite various international conventions and national policies in place to improve green cover, there is a decline in global forest cover.
    • Dependence on forests by nearly 18% of the global human population has put immense pressure on ecosystems; in India, this has resulted in the degradation of 41% of its forests.

    Why conserve forests?

    • Covering nearly 30% land surface of the earth, forests around the globe provide a wide variety of ecosystem services and support countless and diverse species.
    • They also stabilise the climate, sequester carbon and regulate the water regime.

    Need for restoration

    • Restoration in laymen’s terms is bringing back the degraded or deforested landscape to its original state by various interventions to enable them to deliver all the benefits.
    • Building and maintaining activities help to improve ecological functions, productivity and create resilient forests with multifarious capabilities.
    • India’s varied edaphic, climatic and topographic conditions are spread over 10 bio-geographical regions and four biodiversity hotspots, sheltering 8% of the world’s known flora and fauna.

    India’s dependency on forest resources

    • Out of its 21.9% population living under the poverty line, nearly 275 million people including local tribals depend on the forest for subsistence.
    • The intricate link between poverty and environmental degradation was first highlighted by India at the first UN global conference on the human environment in Stockholm.
    • Though India’s increasing economic growth is helping to eliminate poverty, there is continued degradation and a growing scarcity of natural resources.
    • Further, encroachment of nearly 1.48 MHA of forest and grazing in nearly 75% of forest area is also linked to the livelihood of local communities.
    • The participation of local communities with finances for incentives and rewards is essential to redress this complex riddle.

    Strategies adopted by India

    Ans. Bonn Challenge

    • To combat this, India joined the Bonn Challenge with a pledge to restore 21 MHA of degraded and deforested land which was later revised to 26 MHA to be restored by 2030.
    • The first-ever country progress report under the Bonn Challenge submitted by India by bringing 9.8 million hectares since 2011 under restoration is an achievement.
    • However, continued degradation and deforestation need to be tackled effectively to achieve the remaining target of restoration by addressing various challenges.

    Key challenges

    • Local ecology with a research base: forest restoration and tree planting are leading strategies to fight global warming by way of carbon sequestration.
    • However, planting without considering the local ecology can result in more damage.
    • Similarly, planting a forest in the wrong places such as savannah grasslands could be disastrous for local biodiversity.

    Best strategy: Natural Forest Restoration

    • Luckily recent research has shown that naturally regenerated forests tend to have more secure carbon storage.
    • Being less tech-sensitive, cost-effective and conserving more biodiversity, natural forest restoration is becoming more widely accepted.

    Limitations to India

    • Nearly 5.03% of Indian forests are under protection area (PA) management needing specific restoration strategies.
    • The remaining areas witness a range of disturbances including grazing, encroachment, fire, and climate change impacts that need area-specific considerations.
    • Further, much of the research done so far on restoration is not fully compatible with India’s diverse ecological habitats hence warranting due consideration of local factors.
    • The involvement of multiple stakeholders in forest restoration is bound to cause a conflict of interests among different stakeholders; along with low priority and insufficient funding, it becomes even more challenging.

    Policy measures

    • There have been remarkable initiatives to involve local people in the protection and development of forests by forming joint forest management committees (JFMC).
    • However, a review of their functionality and performance is essential to make them more dynamic and effective to scale up their involvement.
    • Therefore, negotiations with a wide range of stakeholders including these committees for resolving conflicts and fulfilling restoration objectives are a must and a challenging feat to reach a suitable trade-off.

    Way forward

    • Adequate financing is one of the major concerns for the success of any interventions including restoration.
    • The active approach of restoration which includes tree planting and the involvement of communities seeks incentives and rewards and make the whole affair quite cost-intensive.
    • The contribution of corporates in restoration efforts so far has been limited to 2% of the total achievement.
    • Hence, alternate ways of financing such as involving corporates and dovetailing restoration activities with ongoing land-based programmes of various departments can help to make it easy for operation.
    • Apart from these specific challenges, the common barriers to restoration as identified globally also need critical review before placing the required methodologies and area-specific strategies in place.

    Conclusion

    • Active engagement of stakeholders including non-governmental organizations, awareness and capacity building of stakeholders with enabling policy interventions and finance can help a lot to achieve restoration objectives for India.
    • The need of the hour is an inclusive approach encompassing these concerns with the required wherewithal.

  • Govt moots easy clearance for Forest Land use

    The government has proposed absolving agencies involved in national security projects and border infrastructure projects from obtaining prior forest clearance from the Centre as part of amendments to the existing Forest Conservation Act (FCA).

    About Forest (Conservation) Act, 1980

    • The FCA is the principal legislation that regulates deforestation in the country.
    • It prohibits the felling of forests for any “non-forestry” use without prior clearance by the central government.
    • The clearance process includes seeking consent from local forest rights-holders and from wildlife authorities.
    • The Centre is empowered to reject such requests or allow it with legally binding conditions.
    • In a landmark decision in 1996, the Supreme Court had expanded the coverage of FCA to all areas that satisfied the dictionary definition of a forest; earlier, only lands specifically notified as forests were protected by the enforcement of the FCA.

    What is the proposed amendment?

    • The proposed amendment is part of a larger rationalizing of existing forest laws for infrastructure projects.
    • The act was regressively interpreted over the right of way of railways, highways.
    • As of today a landholding agency (Rail, NHAI, PWD, etc) is required to take approval under the Act as well as pay stipulated compensatory levies.
    • They are required to pay Net Present Value (NPV), Compensatory Afforestation (CA), etc. for use of such land which was originally been acquired for non-forest purposes.

    Other proposals

    • The Environment Ministry has proposed provisions for penal compensation to make good for the damages already done to trees in forest land.
    • The document also proposes removing zoos, safaris, Forest Training infrastructures from the definition of “non-forestry” activities.
    • The current definition restricts the way money collected as part of compensatory cess can be spent towards forest conservation purposes.

    Previous attempts made

    • Previous attempts to amend acts linked to forest laws have been controversial.
    • There was a plan to amend the Indian Forest Act, 1927, that deals with the rights of forest dwellers, in an attempt to address contemporary challenges to the country’s forests.
    • The draft law had been sent to key forest officers in the States for soliciting comments and objections.
    • It drew flak from activists as well as tribal welfare organizations.
    • The government withdrew the draft and has said that a newer updated version was on the anvil.

  • Probe shows use of toxic material in firecrackers: Supreme Court

    The Supreme Court has said a preliminary enquiry by the CBI into the firecracker industry, including in Tamil Nadu, revealed rampant violation of its ban on use of toxic ingredients like Barium and its salts.

    Air Pollution created by firecrackers

    • Firing crackers increase the concentration of dust and pollutants in the air.
    • After firing, the fine dust particles get settled on the surrounding surfaces which are packed with chemicals like copper, zinc, sodium, lead, magnesium, cadmium and pollutants like oxides of sulphur and nitrogen.
    • These invisible yet harmful particles affect the environment and in turn, put our health at stake.

    Harmful elements used

    • Copper: Irritates the respiratory tract.
    • Cadmium: Leads to anemia by reducing the capacity of blood to carry oxygen.
    • Zinc: Can cause metal fume fever and induces vomiting.
    • Lead: Harms the nervous system.
    • Magnesium: Metal fume fever is caused by Magnesium fumes.
    • Sodium: It is a highly reactive element and caused burns when it is combined with moisture.

    Why is the issue in news now?

    Ans. Barium content

    • A chemical analysis of the samples of finished and semi-finished firecrackers and raw materials taken from the manufacturers showed Barium content.
    • The court stated that loose quantities of Barium were purchased from the market.
    • Also, firecracker covers did not show the manufacture or expiry dates.

    Issues with Barium

    • Barium nitrate, which emits green flames when a cracker is lit, is a metal oxide that increases both air and noise pollution.
    • There is is no clarity on whether barium nitrate can actually be used or not.

    Alternatives: Green Crackers

    • The new CSIR-NEERI formulation for green crackers has NO barium nitrate — one of the key ingredients of traditional firecrackers.
    • These crackers have been named “safe water releaser (SWAS)”, “safe minimal aluminium (SAFAL)” and “safe thermite cracker (STAR)”.
    • The three crackers release water vapour or air as a dust suppressant and diluent for gaseous emissions.
    • These products can only be manufactured by those who have signed a non-disclosure agreement (NDA) with CSIR-NEERI.
    • The green crackers are sold with a unique logo on the box, and will also have a QR code with production and emission details.

  • Wastewater Treatment in India

    Sewage treatment plants (STPs) in India are able to treat a little more than a third of the sewage generated per day, according to the latest report of the Central Pollution Control Board (CPCB).

    What is Wastewater?

    Wastewater is used water from any combination of domestic, industrial, commercial or agricultural activities, surface runoff/ stormwater, and any sewer inflow or sewer infiltration.

    In everyday usage, wastewater is commonly a synonym for:

    • Sewage also called domestic wastewater or municipal wastewater which is wastewater that is produced by a community of people.
    • Industrial wastewater, water-borne waste generated from a variety of industrial processes, such as manufacturing operations, mineral extraction, power generation, or water and wastewater treatment.
    • Cooling water, released with potential thermal pollution after use to condense steam or reduce machinery temperatures by conduction or evaporation
    • Leachate, precipitation containing pollutants dissolved while percolating through ores, raw materials, products, or solid waste
    • Return flow, carrying suspended soil, pesticide residues, or dissolved minerals and nutrients from irrigated cropland
    • Surface runoff, the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil.
    • Urban runoff, including water used for outdoor cleaning activity and landscape irrigation in densely populated areas created by urbanization
    • Agricultural wastewater, generated from confined animal operations

    Wastewater in India

    • India generated 72,368 MLD (million litres per day) whereas the installed capacity of STPs was 31,841 MLD (43.9 per cent), according to the report.

    Treatment facilities available

    • Of this installed capacity, developed and operationalized capacity was 26,869 MLD (84 per cent).
    • Of the total operationalised capacity, 20,235 MLD (75 per cent) was the actual utilised capacity.
    • In other words, out of total 72,368 MLD sewage generated every day, only 20,235 MLD is treated.

    Skewed distribution

    • Five states and Union Territories (UT) — Maharashtra, Gujarat, Uttar Pradesh, Delhi and Karnataka — account for 60 per cent of the total installed treatment capacity of the country.
    • These, along with five other states and UTs — Madhya Pradesh, Haryana, Punjab, Tamil Nadu and Rajasthan — alone constitute 86 per cent of the total installed capacity.
    • Arunachal Pradesh, Andaman & Nicobar Islands, Lakshadweep, Manipur, Meghalaya and Nagaland have not installed sewage treatment plants.
    • There are states like Bihar which do have a small installed capacity of STPs. But on the operational front, they score a zero.
    • Chandigarh ranks first in terms of total sewage generated to what is actually treated. It generates 188 MLD of sewage and has an operational capacity to treat 271 MLD.

    Major issue: Reuse of sewage

    • The reuse of treated sewage is an issue which hasn’t assumed much importance in the policy planning of many state governments.
    • Treated sewage water can be reused for horticulture, irrigation, washing activities (road, vehicles and trains), fire-fighting, industrial cooling, toilet flushing and gardening.
    • The proportion of the reuse of treated sewage is maximum in Haryana (80 per cent) followed by Puducherry (55 per cent), Delhi (50 per cent), Chandigarh (35 per cent), Tamil Nadu (25 per cent), Madhya Pradesh (20 per cent) and Andhra Pradesh (5 per cent).

  • WHO tightens Global Air Quality norms

    The World Health Organisation (WHO) in its first-ever update since 2005 has tightened global air pollution standards.

    Global Air Quality Guidelines (AQGs) 2021

    • WHO announces limits for six pollutant categories —particulate matter (PM) 2.5 and 10, ozone (O3), nitrogen dioxide (NO2) sulphur dioxide (SO2) and carbon monoxide (CO).

    Air quality standards in India

    • India aligns with the WHO guidelines only in the case of ozone and carbon monoxide, as these have not changed. But both NO2 and SO2 guidelines are tighter than the current Indian standard.
    • The move doesn’t immediately impact India as the National Ambient Air Quality Standards (NAAQS) don’t meet the WHO’s existing standards.
    • The government has a dedicated National Clean Air Programme that aims for a 20% to 30% reduction in particulate matter concentrations by 2024 in 122 cities, keeping 2017 as the base year.

    Significance of WHO’s AQG

    Ans. It sets the stage for eventual shifts in policy

    • WHO move sets the stage for eventual shifts in policy in the government towards evolving newer stricter standards.
    • This will soon become part of policy discussions — much like climate targets to reduce greenhouse gas emissions keep getting stricter over time.
    • Once cities and States are set targets for meeting pollution emission standards, it could lead to overall changes in national standards.

    Challenges for India

    • The current challenge in India is to meet its national ambient air quality standards in all the regions.
    • The hard lockdown phases during the pandemic have demonstrated the dramatic reduction that is possible when local pollution and regional influences can be minimised.
    • This has shown that if local action is strengthened and scaled up at speed across the region, significant reduction to meet a much tighter target is possible.
    • The influence of geo-climatic attributes is quite pronounced in all regions of India, which further aggravates the local build-up of pollution.
    • This is further worsened due to the rapid proliferation of pollution sources and weak air quality management systems.
    • India may require a more nuanced regional approach to maximise benefits and sustain air quality gains.

    Conclusion

    • Air pollution is a threat to health in all countries, but it hits people in low- and middle-income countries the hardest.
    • WHO’s new Air Quality Guidelines are an evidence-based and practical tool for improving the quality of the air on which all life depends.

  • Rhino Horn Reverification Exercises

    Assam will mark World Rhino Day — September 22 — with a special ceremony by burning a stockpile of nearly 2,500 horns of the one-horned rhinoceros.

    Rhino Horn Reverification

    • The public ceremony — scheduled at Bokakhat in Kaziranga National Park (KNP) has been publicized as a “milestone towards rhino conservation” aimed at “busting myths about rhino horns”.
    • It’s a loud and clear message to the poachers and smugglers that such items have no value.
    • Thus the case for the destruction of horns — a process that is in compliance with Section 39(3)(c) of the Wildlife (Protection) Act of 1972.

    Why are Rhinos poached for horns?

    • 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.

    Try this PYQ:

    Consider the following statements:

    1. Asiatic lion is naturally found in India only.
    2. Double-humped camel is naturally found in India only.
    3. One-horned rhinoceros is naturally found in India only.

    Which of the statements given above is/are correct?

    (a) 1 only

    Back2Basics: 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.

  • Species in news: Sea Cucumber

    In a swift operation, the Indian Coast Guard (ICG) at Mandapam, Tamil Nadu seized two tonnes of sea cucumber, a banned marine species.

    Sea Cucumbers

    • Sea cucumbers are part of a larger animal group called echinoderms, which also contains starfish and sea urchins.
    • Their body shape is similar to a cucumber, but they have small tentacle-like tube feet that are used for locomotion and feeding.
    • One way that sea cucumbers can confuse or harm predators is by propelling their own toxic internal organs from their bodies in the direction of an attacker.
    • The organs grow back, and it may save them from being eaten.
    • They are found in virtually all marine environments throughout the world, from shallow to deep-sea environments.
    • They are benthic, meaning they live on the ocean floor. However, their larvae are planktonic, meaning they float in the ocean with the currents.

    Conservation status

    • Sea cucumber in India is treated as an endangered species listed under schedule I of Wildlife Protection Act of 1972.
    • It is primarily smuggled from Tamil Nadu to Sri Lanka in fishing vessels from Ramanathapuram and Tuticorin districts.

    (IUCN status is not available for this species)

  • How are Humboldts different from other penguins?

    Last week, Mumbai’s Byculla Zoo announced the addition of two new Humboldt penguin chicks this year.

    Humboldt Penguins

    • Humboldt penguins are medium-sized species among at least 17 species.
    • The exact number of distinct species is debated, but it is generally agreed that there are between 17 and 19 species.
    • The largest, the Emperor penguin, stands at over 4 ft tall while the Little penguin has a maximum height of 1 ft. Humboldt penguins have an average height of just over 2 ft.
    • The Humboldt penguin (Spheniscus Humboldt) belongs to a genus that is commonly known as the ‘banded’ group.’

    Relation with the Humboldt Oceanic Current

    • Humboldt penguins are endemic to the Pacific coasts of Chile and Peru.
    • They are so named because their habitat is located near the Humboldt Current, a large oceanic upwelling characterized by cold waters.

  • Pseudo-melanism in Tigers of Simlipal

    A team of scientists has resolved the genetic mystery of Simlipal’s so-called black tigers.

    What are Black Tigers?

    • Tigers have a distinctive dark stripe pattern on a light background of white or golden.
    • A rare pattern variant, distinguished by stripes that are broadened and fused together, is also observed in both wild and captive populations.
    • This is known as pseudo-melanism, which is different from true melanism, a condition characterized by unusually high deposition of melanin, a dark pigment.
    • This pseudo-melanism is linked to a single mutation in Transmembrane Aminopeptidase Q (Taqpep), a gene responsible for similar traits in other cat species.

    Where are they mostly found?

    • While truly melanistic tigers are yet to be recorded, pseudo-melanistic ones have been camera-trapped repeatedly, and only, in Simlipal, a 2,750-km tiger reserve in Odisha, since 2007.
    • Launched in 2017, the study was the first attempt to investigate the genetic basis for this unusual phenotype (appearance).

    Why they are rare?

    • Mutants are genetic variations which may occur spontaneously, but not frequently, in nature.
    • A cub gets two copies of each gene from both parents, and a recessive gene can show up only in the absence of the dominant one.
    • So, two normal-pattern tigers carrying the recessive pseudo-melanism gene will have to breed together for a one-in-four probability of giving birth to a black cub.
    • But recessive genes are rare and it is unlikely that two unrelated tigers will carry the same one and pass it on together to a cub.

    Connection with Simlipal TR

    • In an ideal tiger world, where far-ranging individuals are never short of choices for partners, that makes succession of black tigers a rarity.
    • Under exceptional circumstances, a black tiger may succeed as part of a very small population that is forced to inbreed in isolation for generations.
    • As it turned out, that is what happened at Simlipal.
    • Pseudo-melanistic tigers are also present in three zoos in India — Nandankanan (Bhubaneswar), Arignar Anna Zoological Park (Chennai) and Bhagwan Birsa Biological Park (Ranchi) — where they were born in captivity.
    • All of them have ancestral links to one individual from Simlipal.

    What about natural selection?

    • Natural selection eliminates the weakest from a gene pool, and the traits of the more successful get passed on.
    • Niche modelling, the study said, shows higher frequency of melanistic leopards in darker tropical and subtropical forests than in drier open habitats.
    • Likewise, darker coats may confer a selective advantage in both hunting and avoiding hunters in Simlipal’s tropical moist deciduous and semi-evergreen closed-canopy forest, with a relatively darker understory.

    Back2Basics: Project Tiger

    • Project Tiger is a tiger conservation program launched in April 1973 during PM Indira Gandhi’s tenure.
    • In 1970 India had only 1800 tigers and Project Tiger was launched in Jim Corbett National Park.
    • The project is administrated by the National Tiger Conservation Authority (NTCA).
    • It aims at ensuring a viable population of Bengal tigers in their natural habitats, protecting them from extinction etc.
    • Under this project the govt. has set up a Tiger Protection Force to combat poachers and funded relocation of villagers to minimize human-tiger conflicts.
