  • What is a Carbon Market, and why does India want to create one?

    The Bill to amend the Energy Conservation Act, 2001 seeks to establish a domestic carbon market and facilitate trade in carbon credits.

    What are Carbon Credits?

    • Carbon credits are measurable, verifiable emission reductions from certified climate action projects.
    • These projects reduce, remove or avoid greenhouse gas (GHG) emissions.
    • But they also bring a whole host of other positive benefits, for example, they empower communities, protect ecosystems, restore forests or reduce reliance on fossil fuels.
    • Projects must adhere to a rigorous set of criteria to pass verification by third-party agencies and a review by a panel of experts at a leading carbon offset standard.
    • After an organization or an individual buys a carbon credit, the credit is permanently retired so it can’t be reused.

    What are Carbon Markets?

    • Carbon markets are regulatory structures that allow, in particular, oil and gas-intensive companies or heavy industry (or, in the case of COP25, countries) to reduce their economic footprint through a series of incentives.
    • The idea behind this system is that the most polluting countries can purchase the right to pollute more from countries that have not reached their emissions limits.
    • The 1997 Kyoto Protocol turned polluting emissions into a commodity.
    • For example, the European Union Emissions Trading System (EU ETS) is the largest in the world and has been in operation since 2015.

    How is the concept evolved?

    • When the world evolved the ‘clean development mechanism’ (CDM) after the Kyoto Protocol agreement of 1997 as companies in the developing world could put up projects.
    • These include renewable energy or afforestation — that helped reduce carbon dioxide emissions, and earn ‘credits’ that could be sold in the market.
    • It was expected that these credits would be bought by the developed countries that had committed to emissions cuts under the Protocol.
    • Thus emerged the CDM market, aka ‘compliance market’. Alongside, environmentally conscious entities also started buying these carbon credits (or offsets) — the ‘voluntary market’.

    What is the status now?

    • This system functioned well for a few years.
    • But the market collapsed because of the lack of demand for carbon credits.
    • As the world negotiated a new climate treaty in place of the Kyoto Protocol, the developed countries no longer felt the need to adhere to their targets under the Kyoto Protocol.
    • A carbon market was envisaged to work under the successor Paris Agreement, but its details are still being worked out.

    Global successes

    • Domestic or regional carbon markets are already functioning in several places, most notably in Europe, where an emission trading scheme (ETS) works on similar principles.
    • Industrial units in Europe have prescribed emission standards to adhere to, and they buy and sell credits based on their performance.
    • China, too, has a domestic carbon market.

    Mechanism in India

    • A similar scheme for incentivizing energy efficiency has been running in India for over a decade now.
    • This BEE scheme, called- Perform, Achieve and Trade (PAT) Scheme allows units to earn efficiency certificates if they outperform the prescribed efficiency standards.
    • The laggards can buy these certificates to continue operating.

    What does new Amendment seeks to bring?

    • The new carbon market that is proposed to be created through this amendment to the Energy Conservation Act, would be much wider in scope.
    • Although the details of this carbon market are not yet known, it is likely to be on the lines of the European ETS, facilitating the buying and selling of carbon credits.

  • Earth has recorded its shortest day since the 1960s- why?

    On June 29, the Earth completed one full spin — a day — in 1.59 milliseconds less than its routine 24 hours. It was the shortest day recorded since the 1960s.

    Note: A millisecond is one-thousandth of a second.

    Earth spinning faster

    • While the Earth has been completing its rotations faster in recent years, when looked at over a much longer period of time, our planet is actually spinning slower.
    • Every century, the Earth takes a few milliseconds longer to complete one rotation — and on average, days are actually getting longer.
    • So, 1.4 billion years ago, a day would have ended in less than 19 hours,

    How did scientists find that?

    • Scientists got to know by using precise atomic clocks to measure the Earth’s rotational speed.

    Why are days getting shorter these days?

    • Scientists aren’t entirely sure.
    • Something has changed and changed in a way we haven’t seen since the beginning of precise radio astronomy in the 1970s.

    Factors attributing Earth’s Spin

    (1) Tidal Braking

    • The research attributed the larger trend of the Earth’s slower spin mostly to the gravitational pull of the Moon, which causes tidal friction and slows down the Earth’s rotations.

    (2) Climate change-induced surface variations

    • Melting ice sheets in Greenland and Antarctica
    • Changes in ocean circulation

    (3) Geomorphic factors

    • Movements in the planet’s inner molten core
    • Seismic activity
    • Wind speed, and shifting atmospheric gases

    (4) Chandler wobble phenomenon

    • This refers to the small deviation in the movement of Earth’s geographical poles.
    • The normal amplitude of the Chandler wobble is about three to four metres at Earth’s surface, but from 2017 to 2020 it disappeared.

    (5) Other propositions

    • Activities that push mass towards the centre of the Earth will hasten the planet’s rotation.
    • Anything that pushes mass outwards will slow down the spin, a report noted.

    What can happen if the Earth continues to spin faster on a sustained basis?

    • To ensure that the time on clocks matches the speed of the Earth’s rotation, a system of leap seconds has been used since the 1970s.
    • They involve one-second adjustments to Universal Coordinated Time (UTC), the time standard used to synchronize clocks around the world.
    • Due to the long-term slowing in the planet’s spin, 27 leap seconds have been added to UTC.
    • However, if the Earth continues to spin faster and days subsequently become shorter, scientists may have to introduce the first ever ‘negative leap second,’ which involves subtraction of a second from clocks.

  • Cabinet nod for Glasgow Climate Pledges

    India ratified pledges made by Prime Minister in Glasgow to accelerate the country’s reliance on renewable energy to power the economy and be effectively free from use of fossil fuels by 2070.

    Why discuss them?

    • The approved pledges were fewer than those PM committed to.

    What is NDC (Nationally Determined Commitments)?

    • NDCs are at the heart of the Paris Agreement and the achievement of these long-term goals.
    • They embody efforts by each country to reduce national emissions and adapt to the impacts of climate change.
    • The Paris Agreement (Article 4, paragraph 2) requires each Party to prepare, communicate and maintain successive NDCs that it intends to achieve.
    • Parties shall pursue domestic mitigation measures, with the aim of achieving the objectives of such contributions.
    • The agreement requests each country to outline and communicate their post-2020 climate actions, known as their NDCs.

    India’s NDC

    • India’s NDC, or nationally determined commitments, have been updated with these two promises, both of which are enhancements of existing targets, and would be submitted to the UN climate body.
    • The 2015 Paris Agreement requires every country to set self-determined climate targets which have to be progressively updated with more ambitious goals every few years.
    • India’s first NDC was submitted in 2015, just before the Paris Agreement was finalised.

    India’s original NDC contained three main targets for 2030:

    1. A 33 to 35 per cent reduction in emissions intensity (or emissions per unit of GDP) from 2005 levels
    2. At least 40 per cent of total electricity generation to come from non-fossil renewable sources
    3. An increase in forest cover to create an additional carbon sink of 2.5 to 3 billion tonnes of carbon dioxide equivalent

    Commitment made at Glasgow

    • At the Glasgow meeting last year, Modi promised to strengthen India’s climate commitments.
    • He made five promises, and called it the ‘Panchamrit’, the nectar that Indians prepare using five ingredients.
    • Two of these were upward revision of existing targets, the ones that have been made official and put in the updated NDC. Accordingly,
    1. India will now reduce its emission intensity by at least 45 per cent, instead of just 33 to 35 per cent, from 2005 levels by 2030.
    2. Also, it would now ensure that at least 50 per cent of its total electricity generation, not just 40 per cent, would come from renewable sources by 2030.
    3. The forestry target has not been touched.

    India’s climate targets: Existing and New

    • PM had said that at least 500 GW of India’s installed electricity generation capacity in 2030 would be based on non-fossil fuel sources.
    • Also, he had promised that the country would ensure avoided emissions of at least one billion tonnes of carbon dioxide equivalent between now and 2030.
    • These two promises have not been converted into official targets.
    • But these are closely linked with others, and any progress on official targets would get reflected in these goals as well.

    What about Net Zero?

    • Modi had also announced a net zero target for India for the year 2070.
    • Net zero is a situation in which a country’s greenhouse gas emissions are offset entirely, either by absorption of carbon dioxide.
    • This may be done through natural processes like photosynthesis in plants, or through physical removal of greenhouse gases using futuristic technologies.
    • But net zero is a long-term target and does not qualify to be included in the NDC which seeks five to 10 year climate targets from countries.

    India’s progress

    • The upward revision of the two climate targets — those relating to reductions in emissions intensity and proportion of non-fossil sources in electricity generation — do not come as a surprise.
    • India is on way to achieve its existing targets well ahead of the 2030 timeline.
    • India’s emissions intensity was 24 per cent lower than the 2005 levels in the year 2016 itself, the last year for which official numbers are available.
    • It is very likely that the 33 to 35 per cent reduction target has already been achieved, or is very close to being achieved.
    • A further reduction of 10-12 per cent from here, to meet the new target, does not appear too challenging, even though these reductions get progressively tougher to achieve.
    • The other target — having at least 40 per cent of electricity coming from non-fossil fuels — has officially been reached.

    Tricky Glasgow promises

    Two promises that Modi had made in Glasgow have not been converted into official targets:

  • Wildlife Protection Bill gets LS nod

    The Lok Sabha passed the Wildlife (Protection), Amendment Bill, with no significant modifications to the version of the Bill presented in the House for discussion.

    What is the Wildlife (Protection) Act, 1972?

    • WPA provides for the protection of the country’s wild animals, birds and plant species, in order to ensure environmental and ecological security.
    • It provides for the protection of a listed species of animals, birds and plants, and also for the establishment of a network of ecologically-important protected areas in the country.
    • It provides for various types of protected areas such as Wildlife Sanctuaries, National Parks etc.
    • The act is also against Taxidermy, which is the preservation of a dead wild animal as a trophy, or in the form of rugs, preserved skins, antlers, horns, eggs, teeth, and nails.
    • In the case of wild birds and reptiles, the act also forbids disturbing or damaging their eggs.
    • The act was amended in the year 2006 and its purpose is to strengthen the conservation of tigers and other endangered species by combating crimes against them through the special Crime Control Bureau.

    There are six schedules provided in the WPA for protection of wildlife species which can be concisely summarized as under:

    Schedule I: These species need rigorous protection and therefore, the harshest penalties for violation of the law are for species under this Schedule.
    Schedule II: Animals under this list are accorded high protection. They cannot be hunted except under threat to human life.
    Schedule III & IV: This list is for species that are not endangered. This includes protected species but the penalty for any violation is less compared to the first two schedules.
    Schedule V: This schedule contains animals which can be hunted.
    Schedule VI: This list contains plants that are forbidden from cultivation.

    Wildlife (Protection) Amendment Bill: Key Features

    (1) CITES

    • CITES is an international agreement between governments to ensure that international trade in specimens of wild animals and plants does not threaten the survival of the species.
    • Under CITES, plant and animal specimens are classified into three categories (Appendices) based on the threat to their extinction.
    • The Convention requires countries to regulate the trade of all listed specimens through permits.
    • It also seeks to regulate the possession of live animal specimens. The Bill seeks to implement these provisions of CITES.

    (2) Obligations under CITES:  

    • The Bill provides for the central government to designate a: (i) Management Authority, which grants export or import permits for trade of specimens, and (iii) Scientific Authority, which gives advice on aspects related to impact on the survival of the specimens being traded.
    • Every person engaging in trade of a scheduled specimen must report the details of the transaction to the Management Authority.
    • As per CITES, the Management Authority may use an identification mark for a specimen.
    • The Bill prohibits any person from modifying or removing the identification mark of the specimen.
    • Additionally, every person possessing live specimens of scheduled animals must obtain a registration certificate from the Management Authority.

    (3) Rationalising schedules

    • Currently, the Act has six schedules for specially protected plants (one), specially protected animals (four), and vermin species (one).
    • Vermin refers to small animals that carry disease and destroy food.
    • The Bill reduces the total number of schedules to four by:
    1. Reducing the number of schedules for specially protected animals to two (one for greater protection level)
    2. Removes the schedule for vermin species
    3. Inserts a new schedule for specimens listed in the Appendices under CITES (scheduled specimens)

    (4) Invasive alien species

    • The Bills empowers the central government to regulate or prohibit the import, trade, possession or proliferation of invasive alien species.
    • Invasive alien species refers to plant or animal species which are not native to India and whose introduction may adversely impact wild life or its habitat.
    • The central government may authorise an officer to seize and dispose the invasive species.

    (5) Control of sanctuaries

    • The Act entrusts the Chief Wild Life Warden to control, manage and maintain all sanctuaries in a state.
    • The Chief Wild Life Warden is appointed by the state government.
    • The Bill specifies that actions of the Chief Warden must be in accordance with the management plans for the sanctuary.
    • These plans will be prepared as per guidelines of the central government, and as approved by the Chief Warden.
    • For sanctuaries falling under special areas, the management plan must be prepared after due consultation with the concerned Gram Sabha.
    • Special areas include a Scheduled Area or areas where the Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006 is applicable.
    • Scheduled Areas are economically backward areas with a predominantly tribal population, notified under the Fifth Schedule to the Constitution.

    (6) Conservation reserves

    • Under the Act, state governments may declare areas adjacent to national parks and sanctuaries as a conservation reserve, for protecting flora and fauna, and their habitat.
    • The Bill empowers the central government to also notify a conservation reserve.

    (7) Surrender of captive animals

    • The Bill provides for any person to voluntarily surrender any captive animals or animal products to the Chief Wild Life Warden.
    • No compensation will be paid to the person for surrendering such items.
    • The surrendered items become property of the state government.

    Back2Basics: CITES

    • CITES stands for the Convention on International Trade in Endangered Species of Wild Fauna and Flora.
    • It is as an international agreement aimed at ensuring “that international trade in specimens of wild animals and plants does not threaten their survival”.
    • It was drafted after a resolution was adopted at a meeting of the members of the International Union for Conservation of Nature (IUCN) in 1963.
    • It entered into force on July 1, 1975, and now has 183 parties.
    • The Convention is legally binding on the Parties in the sense that they are committed to implementing it; however, it does not take the place of national laws.
    • India is a signatory to and has also ratified CITES convention in 1976.

    CITES Appendices

    • CITES works by subjecting international trade in specimens of selected species to certain controls.
    • All import, export, re-exports and introduction from the sea of species covered by the convention has to be authorized through a licensing system.

    It has three appendices:

    • Appendix I includes species threatened with extinction. Trade-in specimens of these species are permitted only in exceptional circumstances.
    • Appendix II provides a lower level of protection.
    • Appendix III contains species that are protected in at least one country, which has asked other CITES Parties for assistance in controlling trade.

  • E-waste management

    A proposed framework by the Centre for regulating e-waste in India has upset a key link of India’s electronic waste collection system and threatens the livelihood of thousands of people.

    Menace of E-Waste in India

    • Electronic waste, or electronic goods that are past their productive life and old parts, is largely handled by India’s vast informal sector.
    • Spent goods are dismantled and viable working parts refurbished, with the rest making their way into chemical dismantling units.
    • Many of these units are run out of unregulated sweatshops that employ child labour and hazardous extraction techniques.

    Remedy against this: Extended Producer Responsibility (EPR)

    • To address all of this, the Environment Ministry brought the E-waste (Management) Rules, 2016.
    • This introduced a system of Extended Producer Responsibility (EPR) compelling makers of electronic goods to ensure a proportion of the goods they sold every year was recycled.
    • They are expected to maintain records annually demonstrating this.
    • Most companies however did not maintain an in-house unit in charge of recycling and this gave rise to a network of government-registered companies, called Producer Responsibility Organisations (PRO).

    How PROs work?

    • PROs act as an intermediary between manufacturers and formal recycling
    • They are (expected to be) technologically equipped to recycle end-of-life electronic goods safely and efficiently.
    • The PROs typically bid for contracts from companies and arrange for specified quantities of goods to be recycled.
    • They provide companies certified proof of recycling that they then maintain as part of their records. Several PROs work on consumer awareness and enable a supply chain for recycled goods.

    Functional PROs in India

    • As of March 2022, the Central Pollution Control Board (CPCB) has registered 74 PROs and 468 authorised dismantlers.
    • They have a collective recycling capacity of about 1.3 million tonnes.

    What is the extent of E-Waste production in India?

    • The Ministry estimated 7.7 lakh tonnes of e-waste to have been generated in 2018-19.
    • Around one million tonnes in 2019-20 of which only a fifth (about 22% in both years) has been confirmed to be “dismantled and recycled”.

    What is the controversy now?

    • This May, the Ministry issued a draft notification that does away with the PROs and dismantlers and vests all responsibility of recycling with authorised recyclers.
    • Only a handful of authorised recyclers exist in India.
    • Recyclers will source a quantity of waste, recycle them and generate electronic certificates.
    • Companies can buy these certificates equivalent to their annual committed target and thus do not have to be involved with engaging the PROs and dismantlers.
    • Dismantling a fledgling system was detrimental to the future of e-waste management in India.

    What is the rationale behind?

    • The Centre has not explained its rationale for dismantling the existing system in its draft notification.
    • However, a final policy is yet to emerge.
    • The new rules would track the material that went in for recycling with the output claimed by a recycler when they claimed GST (Goods and Services Tax) input credit.

  • UN declares Access to Clean, Healthy Environment as Universal Human Right

    Every person on the planet has the right to live in a clean, healthy environment, as declared United Nations (UN) in a historic resolution.

    Access to Clean, Healthy Environment

    • The resolution recognizes the right to a clean, healthy and sustainable environment as a human right essential for the full enjoyment of all human rights and, among others.
    • It calls upon States and international organizations to adopt policies and scale up efforts to ensure a clean, healthy and sustainable environment for all.
    • The landmark development demonstrates that the member states can unite in the collective fight against the triple planetary crisis of climate change, biodiversity loss and pollution.
    • The declaration sheds light on almost all the rights connected to the health of our environment.
    • The declaration adopted by over 160 UN member nations, including India, is not legally binding.

    Why such move?

    • This right was not included in the Universal Declaration of Human Rights, 1948.
    • So, this is a historic resolution that will change the very nature of international human rights law.
    • The resolution will help to reduce environmental injustices and protection gaps.
    • It can empower people, especially those in vulnerable situations, including environmental human rights defenders, children, youth, women and indigenous people.

    Landmark resolution after 50 years

    • Some 50 years ago, the United Nations Conference on the Environment in Stockholm concluded with a resolution placing environmental issues at the global forefront.
    • Today, over 176 countries have adopted environmental framework laws on the basis of it.
    • From a foothold in the 1972 Stockholm Declaration, these rights have been integrated into constitutions, national laws and regional agreements.
    • In October 2021, it was recognised by the UN Human Rights Council.

    What were other such developments?

    • July 28, 2010, the UN general assembly recognised the right to water and sanitation through its resolution.
    • It stated that clean drinking water and sanitation “are essential to the realisation of all human rights”.
    • In response to this, governments across the world have changed their laws and regulations related to water and sanitation.

    Issues over this declaration

    • The words’ ‘clean’, ‘healthy’ and ‘sustainable’ lack an internationally agreed definition.
    • The text fails to refer to the foundational principle of equity in international environmental law.
    • Nevertheless, this has given more power in the hands of environmental activists to question environmentally destructive actions and policies.

    Back2Basics: Right to Clean Environment in India

    • The right to life has been used in a diversified manner in India.
    • It includes, inter alia, the right to survive as a species, quality of life, the right to live with dignity and the right to livelihood.
    • In India, this has been expressly recognised as a constitutional right under Article 21.
    • It states: ‘No person shall be deprived of his life or personal liberty except according to procedures established by law.’
    • The Supreme Court expanded this negative right in two ways.
    1. Firstly, any law affecting personal liberty should be reasonable, fair and just.
    2. Secondly, the Court recognized several unarticulated liberties that were implied by article 21.
    • It is by this second method that the Supreme Court interpreted the right to life and personal liberty to include the right to a clean environment.

  • Celebrating World Tiger Day

    As the world celebrates yet another World Tiger Day July 29, 2022, there is sobering news.

    Why in news?

    • The International Union for the Conservation of Nature (IUCN) recently confirmed that the tiger has gone extinct in Cambodia, Laos and Vietnam.

    Tigers in India

    • India is home to a third of the global tiger population and the country’s success in saving the big cat is crucial to global efforts to protect their numbers.
    • India was the first country in the world to champion the cause of conservation of the tiger and its natural habitats.
    • The aesthetic, ethical and cultural value of tigers have also proved to be critical factors for saving tigers, which has also ensured the success of tiger conservation in India.

    Why is it necessary to conserve Tigers?

    The tiger is a unique animal that plays a pivotal role in the health and diversity of an ecosystem.

    • Predation balance: It is a top predator which is at the apex of the food chain.
    • Regulation of herbivores: It keeps the population of wild ungulates in check, thereby maintaining the balance between prey herbivores and the vegetation upon which they feed.
    • Ecosystem balance: Therefore, the presence of tigers in the forest is an indicator of the well being of the ecosystem.
    • Tourism: Apart from the ecological services provided by the animal, the tiger also offers direct use such as attracting tourists, which provide incomes for local communities.

    Various efforts to save Tigers

    India is home to 70 percent of the global tiger population. Therefore, the country has an important role to play in tiger conservation.

    [1] Project Tiger

    • The Government of India started ‘Project Tiger’ in 1972 with a view to conserving the animal.
    • As part of this project nine core buffer areas for maintaining tiger population were notified. Now, this has >expanded to 48 tiger reserves.

    [2] CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora)

    • Besides protecting tiger territory, other measures being taken to save the tiger include: curbing wildlife trade through international agreements.
    • CITES is an international agreement between governments aimed at ensuring that international trade in specimens of wild animals and plants, including tigers, does not threaten their survival. India ratified this treaty in 1976.

    [3] Global Tiger Forum and Tiger Range Countries

    • Established in 1994, the Global Tiger Forum is the only inter-governmental body for tiger conservation.
    • Its membership includes seven tiger range countries: Bangladesh, Bhutan, India, Cambodia, Myanmar, Nepal and Vietnam.

    [4] CA|TS

    • 14 tiger reserves have been accredited under CA|TS (Conservation Assured | Tiger Standards) categories.
    • The CA|TS is a set of criteria that examines the management of tiger sites to gauge the success rates of tiger conservation.

    [5] St. Petersburg Declaration

    • This resolution was adopted In November 2010, by the leaders of 13 tiger range countries (TRCs) assembled at an International Tiger Forum in St. Petersburg, Russia
    • It aimed at promoting a global system to protect the natural habitat of tigers and raise awareness among people on white tiger conservation.

    [6] Various NGOs

    • International NGO members consist of World Wildlife Fund, International Fund for Animal Welfare (IFAW), and TRAFFIC.
    • Several national NGOs from India and Nepal are also members.

    Success of these efforts

    The four-year tiger census report, Status of Tigers in India, 2018 shows the number of the big cat has increased across all landscapes.

    The total count has risen to 2,967 from 2,226 in 2014 — an increase of 741 individuals (aged more than one year), or 33%, in four years.

    • At present, India has around 75% of tiger population and its source areas amongst the 13 tiger range countries in the world.
    • 2.24% of country’s geographical area is spread out in 51 tiger reserves in 18 States.

    Various threats to Tigers

    • Despite measures being initiated to protect wild tigers, habitat loss and poaching continue to pose a threat to the animal’s survival.
    • Tiger parts are used in traditional Chinese medicines, tiger skin is used for decorative and medicinal purposes and tiger bones are again used for medicinal purposes for curing body pain, et al.
    • Between 2000 and 2014, TRAFFIC’s research found that parts of a minimum of 1,590 Tigers were seized in Tiger range States, an average of two Tigers per week.

    Other existential threats to tigers

    • Man-Animal conflict: This largely seems a normal phenomenon in India. We broadly remember the case of Tigress Avni which was finally shot dead by the forest officials in Maharashtra.
    • Shrinking habitat: This often leads to territorial conflicts among the Tigers.
    • Issues with Tourism: Excess of tourist activities is problematic for animals. Frequent visits in reserved forests areas disrupt them to move freely for their prey.
    • Climate Change: The effects of climate change and floods are a major problem.  The latest study by WWF shows that Sundarban which is one of the biggest home of tigers in India would sink entirely in 2070.

    Way forward

    • The process of tiger conservation should be more dynamic and compatible with the future possibilities of climatic changes as well.
    • The Forest Department and the Central government can collaborate to protect the natural corridors to ensure the free movement of the tigers for better food resources.
    • Campaigns such as ‘Save the Tiger’ are recommended as effective measures to make people across the country and globe aware of the significance of conserving tiger species.
    • Sensitization of local communities against poaching is also a crucial measure in this regard.
    • We have to make the environment and development co-exist and go hand in hand by planning our future developmental goals in such a manner that our environmental goals are not compromised.

  • Tiger conservation

    Context

    India is now reporting increased tiger numbers, and a recent International Union for Conservation of Nature assessment suggests that tiger numbers have increased by 40% since 2005. This is cause for celebration. But is the rise in tiger numbers enough to prevent their extinction?

    Relations between distribution and genetic variation

    • Decades of research in ecology and evolution suggest that numbers are critical to avoid extinction. 
    • Populations that are smaller than 100 breeding individuals have a high probability of extinction.
    • At the same time, for populations to persist, they should be part of larger landscapes with other such populations that are connected.
    • This is because small populations are subject to chance/random events.
    • These chance events may cause them to lose advantageous genetic variants, while other, detrimental genetic variants might increase in frequency.
    • This process is called genetic drift.
    • Individuals in small populations are more likely to be related, leading to inbreeding.
    • This exposes the many slightly disadvantageous genetic variants that are present in all genomes.
    • When expressed together, these detrimental genetic variants cause inbreeding depression, and reduced survival and reproduction of inbred individuals.
    • A closer look at the distribution of tigers across their range shows that most tiger ‘populations’ are smaller than 100.
    • This raises a question why are we not seeing extinctions happening more often? Is this because tiger populations are connected to each other?

    Research findings about movement of tigers

    • One way to answer the question about not so frequent extinction is to use movement data sourced from radio-collared tigers, often difficult to come by for a rare and endangered species.
    • Alternatively, tigers can be genetically sampled using their excreta/scat, hair and other biological samples from different tiger reserves and analysed in a laboratory.
    • Genetic variants in tiger DNA can be identified and analysed and compared across tiger reserves.
    • Genetic variation in landscape with connectivity: Sets of tiger reserves that show shared genetic variation are well connected — the inference is that the intervening landscapes facilitate connectivity or movement.
    • On the flip side, sets of tiger reserves that share less genetic variation must have barriers or landscapes that impede movement and connectivity.
    • Most land-use types were not too bad for tiger connectivity, including agricultural fields.
    • However, the presence of built-up areas and high traffic roads greatly impeded tiger movement.
    • Results showed that extinction could be avoided if corridors were safeguarded.
    • In summary, as long as we manage landscapes outside tiger reserves to allow tiger movement, and protect prey and tigers inside tiger reserves, tigers are sure to survive in landscapes such as central India.

    Genetic changes in isolated tiger population

    • Black tigers were found only in the Similipal tiger reserve in Odisha.
    • Genome sequences of a litter of zoo tigers that included pseudo-melanistic cubs revealed that a single spelling mistake (or mutation) in a specific gene causes these tigers to look this way.
    • Pseudo-melanistic or black tigers found in Odisha has demonstrated the genetic effects of isolation.
    • Results of the research pointed to genetic drift, or random events that have lead to this genetic variant that causes pseudomelanistic coat colour becoming common only in Similipal.
    • On the other side of India, in Rajasthan, genome sequences from wild tigers reveal that individuals in the Ranthambore tiger reserve show inbreeding.
    • In short, we are seeing the genetic effects of isolation and small population size in wild tigers at some locations.

    Way forward

    • Focus on connectivity: While we celebrate the recovery of tiger populations only by looking at numbers, we must not lose sight of other factors that are critical to their continued survival, such as connectivity.
    • Special attention is needed for populations that are becoming isolated and facing the genetic consequences of such isolation.
    • The future of such populations may depend on genetic rescue or even the introduction of novel genetic variants.

    Conclusion

    We are fortunate that novel genome sequencing technology provides an opportunity to understand tigers much better in the context of their conservation. The future of tigers will require a ‘dialogue’ between such data and management strategies in order to ensure their survival. India is lucky to have so many wild tigers and we must work together to save them.

    Back2Basics: Pseudo-melanism

    • 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 characterised by unusually high deposition of melanin, a dark pigment.
    • 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

  • India adds five more Ramsar Sites

    India has added five more Ramsar sites, or wetlands of international importance, bringing the number of such sites in the country to 54.

    Newly added Ramsar Sites

    1. Karikili Bird Sanctuary, Pallikaranai Marsh Reserve Forest and Pichavaram Mangrove in Tamil Nadu,
    2. Sakhya Sagar in Madhya Pradesh
    3. Pala Wetlands in Mizoram

    What are Wetlands?

    • A wetland is a distinct ecosystem that is flooded by water, either permanently or seasonally, where oxygen-free processes prevail.
    • The primary factor that distinguishes wetlands from other landforms or water bodies is the characteristic vegetation of aquatic plants, adapted to the unique hydric soil.

    Significance of Wetlands

    • Wetlands provide a wide range of important resources and ecosystem services such as food, water, fibre, groundwater recharge, water purification, flood moderation, erosion control, and climate regulation.
    • They are, in fact, are a major source of water and our main supply of freshwater comes from an array of wetlands that help soak rainfall and recharge groundwater.
    • They provide many societal benefits: food and habitat for fish and wildlife, including threatened and endangered species; water quality improvement; flood storage; shoreline erosion control; economically beneficial natural products for human use; and opportunities for recreation, education, and research, etc.

     India and Ramsar Wetlands

    • India’s Ramsar wetlands are spread over 11,000 sq.km — around 10% of the total wetland area in the country — across 18 States.
    • No other South Asian country has as many sites, though this has much to do with India’s geographical breadth and tropical diversity.
    • The UK (175) and Mexico (142) — smaller countries than India — have the most Ramsar sites, whereas Bolivia spans the largest area with 1,48,000 sq.km under the Convention protection.
    • The National Wetland Inventory and Assessment compiled by the ISRO estimates India’s wetlands to span around 1,52,600 square kilometres.

    What makes Ramsar designation significant?

    • Being designated a Ramsar site does not necessarily invite extra international funds.
    • Acquiring this label helps with a locale’s tourism potential and its international visibility.

    Criteria for Ramsar site designation

    To be Ramsar site a place must meet at least one of the criteria as defined by the Ramsar Convention of 1961, such:

    1. Supporting vulnerable, endangered, or critically endangered species or threatened ecological communities or,
    2. If it regularly supports 20,000 or more waterbirds or,
    3. Is an important source of food for fishes,
    4. Spawning ground,
    5. Nursery and/or migration path on which fish stocks are dependent upon.
    6. Static or flowing, fresh, brackish or salt, including areas of marine water the depth of which at low tide does not exceed six metres
    7. Does not include river channels, paddy fields, human-made water bodies/ tanks specifically constructed for drinking water purposes

    Back2Basics: 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.

  • Why is Karnataka opposing Centre’s draft Eco-Sensitive Area norms for Western Ghats?

    The Union Environment Ministry’s latest draft notification on Ecologically Sensitive Areas (ESA) in the Western Ghats is facing stiff opposition in Karnataka.

    What is the news?

    • The MoEFCC had issued a draft notification that demarcated large parts of Karnataka, Tamil Nadu, Gujarat and Maharashtra as eco-sensitive areas.
    • Among these states, Karnataka contains the largest geographical share of the notified areas in the Western Ghats, at 20,668 sq km.

    ESA in Western Ghats

    • In 2013, the Kasturirangan committee had submitted a report which recommended that 37% of the Western Ghats, covering an area of 59,940 sq km be classified as ESA.
    • On the basis of this, several drafts were introduced which were subsequently rejected by the surrounding states, including Karnataka.

    What is ESA?

    • 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.

    Activities Permitted and Prohibited

    • Permitted: Ongoing agricultural or horticultural practices, rainwater harvesting, organic farming, use of renewable energy sources, and adoption of green technology for all activities.
    • Prohibited: Commercial mining, saw mills, industries causing pollution (air, water, soil, noise etc.), the establishment of major hydroelectric projects (HEP), commercial use of wood, Tourism activities like hot-air balloons over the National Park, discharge of effluents or any solid waste or production of hazardous substances.
    • Under regulation: Felling of trees, the establishment of hotels and resorts, commercial use of natural water, erection of electrical cables, drastic change of agriculture system, e.g. adoption of heavy technology, pesticides etc, widening of roads.

    What does the new draft notification for the Western Ghats say?

    • The draft notification demarcates 46,832 sq km in the five states Gujarat, Maharashtra, Karnataka, Goa and Tamil Nadu as ESA in the Western Ghats.
    • Kerala is excluded from the draft notification and it had earlier undertaken the exercise of demarcating ESA in the state by physical verification.
    • Among the five states, 20,668 sq km of the ESA lies in Karnataka, 1,461 sq km in Goa, 17,340 sq km in Maharashtra, 6,914 sq km in Tamil Nadu and 449 sq km in Gujarat.
    • According to the notification, the concerned state governments are responsible for monitoring and enforcing the provisions of the notification.

    What are the curbs that the state governments will have to implement?

    • The draft notification states there shall be a complete ban on mining, quarrying and sand mining in the ESA.
    • All existing mines are to be phased out within five years from the date of issue of the final notification or on the expiry of the existing mining lease.
    • It also bars setting up of new thermal power projects and expansion of existing plants in the sensitive area, and the banning of all new ‘Red’ category industries.
    • The construction of new townships and area development projects will also be prohibited in the areas.
    • ‘Orange’ category industries, with a pollution index score of 41-59, such as jute processing and ‘White’ industries that are considered non-polluting will also be allowed with strict compliance.

    What were the suggestions by the Kasturirangan panel?

    • The panel, formed in 2012, was tasked with the mandate of taking a “holistic view of the issue, and to bring synergy”.
    • It aimed to protecting the environment and biodiversity, while maintaining the needs and aspirations of the local and indigenous people, of sustainable development and environmental integrity of the region.
    • The report had recommended a blanket ban on mining, quarrying, red category industries and thermal power projects.
    • It also stated that the impact study of infrastructural projects on the forest and wildlife should be conducted before permission is given.

    What is Karnataka’s stand on the matter?

    • The Karnataka government has been firm in rejecting the implementation of the guidelines.
    • It has staunchly opposed to the Kasturirangan committee report on Western Ghats.
    • It urged that declaring Western Ghats as ESA would adversely affect the livelihood of people in the region.
    • Environmental experts consider the state government’s decision to be disastrous for the biodiversity of the Western Ghats.
