  • India’s challenge in balancing the emissions and economy

    India faces an uphill task of balancing its climate action with the economic growth. Bridging the energy deficit through renewable energy in cost-effective and increasing urban forestry could help in balancing the both.

    Comparing India’s commitment

    • China’s announcement recently to achieve carbon neutrality, that is, effectively generating net-zero emissions, before 2060 has now shifted focus on India’s commitments.
    • In this context,  let us compare India’s commitments with other countries, based on an independent scientific analysis carried out by the Climate Action Tracker. Major findings of it are:-
    • 1) India is one of the only six countries (amongst the 33 that were assessed), and the only G-20 country, whose climate commitments at Paris are on a path compatible to limit warming well below 2°C.
    • 2) It seems that India is well on its way to achieving its carbon intensity reduction and non-fossil-fuel electricity growth capacity commitments well before the 2030 target year.
    • Even though China’s commitment is likely to lower warming projections by around 0.2 to 0.3 degrees C by 2100, China continues to remain in the “highly insufficient” category.
    • India, despite being the fourth-largest emitter, has consistently kept its commitments in sync with its fair share and will achieve, if not over-achieve, these targets.

    Difference in development and growth levels

    • Development and growth in India are still at an early stage, and our first goal remains increasing the availability of adequate infrastructure for all Indians.
    • A measure of this deficit is that we use only about 0.6 tonnes of oil-equivalent worth of energy per person per year while in China it is 2.36 tonnes per person per year, and is at least 4 tonnes per person per year in the OECD countries.
    • It is, therefore, essential that we rapidly bridge the energy deficit.

    Bridging the energy deficit through renewable and cost-effective manner

    • Cost-effectiveness in renewable electricity has occurred rather rapidly, largely as a result of the global reduction in solar PV and battery prices.
    • Solar electricity is already the cheapest electricity available in India when the sun is shining.
    • It now seems that round-the-clock renewable electricity may be cost-competitive with coal electricity in the near future.
    • This cost-effectiveness of zero-carbon options will emerge in other applications as well.
    • It will involve dedicated action in some of the vital sectors which can generate and sustain employment while adding to the country’s economic growth.
    • It will enable a shift away from emissions-intensive fossil fuels, reducing our dependence on fuel imports.

    Urban forestry to compensate for environmental degradation

    • Increasing urban forestry could help compensate for environmental degradation as a result of rapid urbanisation in several Indian cities.
    • This is vital to restore the flow of crucial ecosystem services, including air quality, and increase the resilience of cities to extreme climatic events.
    • As a result, enhancing biodiversity, minimising human-wildlife conflict and restoring India’s pristine forests by developing dedicated wildlife/biodiversity corridors is an essential next step.

    Way ahead

    • At the developmental crossroads that India stands, the next decade is vital for its own economic growth, its climate action, and its social and ecological well-being.
    • With this in mind, India must focus on its domestic developmental prerogative and disengage them from the pressures that come along with international negotiations, focussing on actions that reduce the development deficits, which also provide strong climate benefits.
    • India must initiate a narrative, discussion and dialogue which focuses on each country taking on commitments that move their carbon trajectory towards the Paris agreement goal of limiting global warming to well below 2°C.

    Consider the question “Development and growth in India still at an early stage which makes the challenge of balancing the commitment to climate action with economic developement more difficult. In light of this, suggest the strategy that India should follow.”

    Conclusion

    India, being at the crossroads of development needs to balance the development goals with its commitment towards climate action.

  • Vulture Action Plan for 2020-25

    Union Minister for Environment, Forests and Climate Change has launched a Vulture Action Plan 2020-25 for the conservation of vultures in the country.

    Vulture Action Plan

    • While the ministry has been carrying out a conservation project for vultures since 2006, the plan is to now extend the project to 2025 to not just halt the decline but to actively increase the vulture numbers in India.
    • There are nine recorded species of vultures in India — the Oriental white-backed, long-billed, slender-billed, Himalayan, red-headed, Egyptian, bearded, cinereous and the Eurasian Griffon.
    • Vulture numbers saw a steep slide — as much as 90 per cent in some species — in India since the 1990s in one of the most drastic declines in bird populations in the world.

    Decline in Populations

    • Between the 1990s and 2007, numbers of three presently critically-endangered species – the Oriental white-backed, long-billed and slender-billed vultures — crashed massively with 99 per cent of the species having been wiped out.
    • The number of red-headed vultures, also critically-endangered now, declined by 91% while the Egyptian vultures by 80%.
    • The Egyptian vulture is listed as ‘endangered’ while the Himalayan, bearded and cinereous vultures are ‘near threatened’.

    Why protect vultures?

    • Vultures are often overlooked and perceived as lowly scavengers, but they play a crucial role in the environments in which they live.
    • The scavenging lifestyle that gives them a bad reputation is, in fact, that makes them so important for the environment, nature and society.
    • Vultures, also known as nature’s cleanup crew, do the dirty work of cleaning up after death, helping to keep ecosystems healthy as they act as natural carcass recyclers.

    Various threats

    • The crash in vulture populations came into limelight in the mid-90s, and in 2004.
    • The cause of the crash was established as diclofenac — a veterinary nonsteroidal anti-inflammatory drug (NSAID) used to treat pain and inflammatory diseases such as gout — in carcasses that vultures would feed off.
    • Just 0.4-0.7 per cent of animal carcasses contaminated with diclofenac was sufficient to decimate 99 per cent of vulture populations.

    Various initiatives

    • The MoEFCC released the Action Plan for Vulture Conservation 2006 with the drugs controller banning the veterinary use of diclofenac in the same year and the decline of the vulture population being arrested by 2011.
    • The Central Zoo Authority (CZA) and Bombay Natural History Society (BNHS) also established the Vulture Conservation Breeding Programme.
    • It has been successful and had three critically-endangered species bred in captivity for the first time.
    • The ministry has now also launched conservation plans for the red-headed and Egyptian vultures, with breeding programmes for both.
    • The Vulture Safe Zone programme is being implemented at eight different places in the country where there were extant populations of vultures, including two in Uttar Pradesh.

  • Lonar Lake, Sur Sarovar declared as Ramsar sites

    The Lonar Lake in Maharashtra and Sur Sarovar, also known as Keetham lake, in Agra, have been added to the list of recognised Ramsar sites.

    Make a note of all freshwater and saltwater lakes in India.

    Lonar Lake

    • Lonar Lake, also known as Lonar crater, is a notified National Geo-heritage Monument, saline (pH of 10.5), Soda Lake, located at Lonar in Buldhana district, Maharashtra.
    • It was created by an asteroid collision with earth impact during the Pleistocene Epoch.
    • It is one of the four known, hyper-velocity, impact craters in basaltic rock anywhere on Earth.
    • It sits inside the Deccan Plateau—a massive plain of volcanic basalt rock created by eruptions some 65 million years ago.

    Sur Sarovar

    • It is a scenic lake just outside Agra on the Agra – Delhi highway (NH 2) and a declared bird sanctuary.
    • The riverine belt of River Yamuna surrounds the area of Sur-Sarovar.
    • It is today home to more than 165 species of migratory and resident birds.
    • It is the same place that inspired the famed poet Soordas to compose the “Bhakti Kavya” one of the finest pieces of devotional poetry.

    Two amongst many

    • India now has 41 wetlands, the highest in South Asia, with two more added to the list of recognised sites of international importance under the treaty of Ramsar Convention.
    • Recently, Kabartal in Bihar’s Begusarai district was recognised as a wetland of international importance, the first such wetland in the State, under the Ramsar Convention.
    • The Asan Conservation Reserve in Dehradun, the first wetland from Uttarakhand to be recognised by Ramsar convention, was added to the list in October this year.

    Back2Basics: 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.
    • 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.

    What is the Ramsar Convention?

    • The Ramsar Convention on Wetlands of International Importance Especially as Waterfowl Habitat is a treaty for the conservation and sustainable use of such sites.
    • The convention, signed in 1971 in the Iranian city of Ramsar, is one of the oldest inter-governmental accords for preserving the ecological character of wetlands.
    • Also known as the Convention on Wetlands, it aims to develop a global network of wetlands for the conservation of biological diversity and for sustaining human life.
    • Over 170 countries are party to the Ramsar Convention and over 2,000 designated sites covering over 20 crore hectares have been recognised under it.

  • Air pollution in India

    Despite efforts from several levels, air pollution is getting worse day by day. The article suggests the strategy to deal with the issue of air pollution.

    Solvable problem

    • Pollution is very much a solvable problem but it cannot be solved on an emergency basis.
    • It has to be dealt with firmly and gradually.
    • Why gradually? Because there are many sources of pollution and it would be prohibitively costly to stop them or even significantly reduce them all at once.

    Replacing existing technologies with existing technology

    • The biggest sources air polltion nationally are cooking fires, coal-fired power plants, various industries, crop residue burning, and construction and road dust. Vehicles are further down on the list.
    • Dealing with all these sources will require a gradual replacement of existing technologies with new technologies.
    • Cooking fires must be replaced with LPG, induction stoves, and other electric cooking appliances.
    • Old coal power plants must be closed and replaced with wind and solar power and batteries while newer plants must install new pollution control equipment.
    • No new coal-fired power plants should be built — with renewables being cheaper, coal is obsolete for power generation.
    • Other industries that use coal will have to gradually switch over to cleaner fuel sources such as gas or hydrogen while becoming more energy-efficient at the same time.
    • Farmers will have to switch crops or adopt alternative methods of residue management.
    • Diesel and petrol vehicles must gradually be replaced by electric or hydrogen fuel cell vehicles running on power generated from renewables.

    Legal measures and issues

    • Governments can make clean investments more profitable and dirty investments less profitable by taxing polluting activities and subsidising clean investments.
    • The judiciary is more powerful but has far less scientific and technical competence.
    • It tends to act only during crises and focus on past mistakes rather than planning to prevent new ones.

    Reforms in regulatory agency

    • Our existing laws do not allow the central and state pollution boards to levy pollution fee or cess based on pollution emissions.
    • Since closing down an industry is a drastic step, it almost never happens.
    • We need a regulatory agency that can levy pollution fee or cess, is that the regulatory decision need not be an all-or-nothing decision.
    • Pollution fees can start small, and the EPA can announce that they will rise by a certain percentage every year.
    • The regulatory agency should be given some independence,like
    • 1) a head appointed for a five-year term removable only by impeachment.
    • 2) a guaranteed budget funded by a small percentage tax on all industries.
    • 3) autonomy to hire staff and to set pollution fees after justification through scientific studies.
    • Three advantages of the regulator with such powers would be-
    • 1) Politicians in power can pass on the blame for decisions on pollution fees to the EPA.
    • 2) Pollution fees raise revenue for the government.
    • 3) If the law establishing an independent EPA is written to require that changes to pollution fees and regulations must be published in advance, and cannot involve abrupt changes, then surprises are avoided.
    • Industry opposition will be muted, especially if industry gets a piece of the revenue to invest in new technologies.

    Conclusion

    Our pollution problem has taken decades to grow into the monster that it is. It can’t be killed in a day. We need the scientific and technical capacity that only a securely funded independent EPA can bring to shrink pollution down to nothing.

  • Places in news: Tristan da Cunha

    The isolated UK Overseas Territory of Tristan da Cunha, the world’s most remote human settlement, has been declared the largest fully protected marine reserves in the Atlantic Ocean at 687,000 square kilometres.

    Note the location of Tristan da Cunha Islands in the Atlantic.

    Tristan da Cunha

    • Tristan da Cunha, which is inhabited by less than 300 humans is a small chain of islands over 6,000 miles from London in the South Atlantic and the water around the islands are considered to be the richest in the world.
    • The mountainous archipelago is home to tens of millions of seabirds and several unique land birds that are comparable to the Galapagos island finches.
    • The island group is also home to the World Heritage Site of Gough and Inaccessible Islands, which is one of the most important seabird islands in the world.

    Significance of protection

    • After joining the UK’s Blue Belt Programme, it will become the largest no-take zone in the Atlantic and the fourth largest on the planet.
    • This will close over 90 per cent of their waters to harmful activities such as bottom-trawling fishing, sand extraction and deep-sea mining.
    • The almost 700,000 square kilometres of the Marine Protection Zone (MPZ) is almost three times the size of the UK and will safeguard the future of sevengill sharks, Yellow-nosed albatrosses and rockhopper penguins.
    • MPZs involve the management of certain natural areas for biodiversity conservation or species protection and are created by delineating zones with permitted and non-permitted areas within that zone.

  • Species in news: Rohanixalus -the frogs of the new genus

    Indian researchers have discovered a genus of tree frog found in the Andaman Islands and the northeast.

    A stand-alone species being mentioned in the news for the first time find their way into the prelims. Make special note here. Usually, note the species and its habitat location (IUCN status if available), in the purview of a generic prelims question.

    Genus Rohanixalus

    • Named after Sri Lankan taxonomist Rohan Pethiyagoda, the frogs of the new genus Rohanixalus are characterised by a rather small and slender body (size about 2 to 3 cm long).
    • It has a pair of contrastingly coloured lateral lines on either side of the body, minute brown speckles scattered throughout the upper body surfaces, and light green coloured eggs laid in arboreal bubble-nests.
    • Based on DNA studies, the new genus is also revealed to be a distinct evolutionary lineage from all previously known tree frog genera.
    • It is the 20th recognised genus of the family Rhacophoridae that comprises 422 known Old World tree frog species found in Asia and Africa.

    Sub-species of this frog

    • There are eight frog species in this genus Rohanixalus.
    • They are known to inhabit forested as well as human-dominated landscapes right from the northeast to Myanmar, Thailand, Malaysia, Indonesia, Vietnam, Laos, and Cambodia, up to southern China.

    Unique features of this genus

    • The genus has several unique behavioural traits including maternal egg attendance where the female (mother) attends the egg clutches until hatching and assists in the release of the tadpoles into the water.
    • During the first three days after egg-laying, the female sits over the eggs and produces a gelatinous secretion with which she glazes the egg mass through the clock-wise movement of her legs.
    • This behaviour provides necessary moisture to the eggs laid on exposed leaf surfaces and protects them from insect predation.

  • Strengthening the public health capacities in disasters

    The article highlights the importance of the robust public healthcare system for the disaster preparedness and suggests linking it with the primary healthcare.

    Reactive approach to disasters

    • In 2005, India enacted the Disaster Management Act, which laid an institutional framework for managing disasters across the country.
    • Under the Act, reactive, ad hoc measures applied in the event of a disaster, was to be replaced with a systematic scheme for prevention, mitigation, and responding to disasters of all kinds.
    • Disaster management considerations were to be incorporated into every aspect of development and the activities of different sectors, including health.
    • While some headway has indeed been achieved, the approach continues to be largely reactive.
    • Significant gaps remain particularly in terms of medical preparedness for disasters.

    Medical preparedness for disasters

    • Two important lessons emerge:-
    • First, health services and their continuing development cannot be oblivious to the possibility of disaster-imposed pressures.
    • Second, the legal framework for disaster management must push a legal mandate for strengthening the public health system.

    Role of private health sector during disaster

    • Instances of overcharging during Covid illustrates how requisitioning of private sector services during disasters can hardly be a dependable option in the Indian context.
    • This is particularly important since the future development of hospital care services is being envisaged chiefly under publicly financed health insurance, which would very likely be private-sector led.
    • The Indian private sector landscape, characterised by weak regulation and poor organisation, is incapable for mounting a strong and coordinated response to disasters.
    • During disasters, the limited regulatory ability could be further compromised.
    • While publicly financed insurance could be a medium to introduce some order into this picture, a large majority of private hospitals in the country are small enterprises which cannot meet the inclusion criteria for insurance.
    • Many of these small hospitals are also unsuitable for meeting disaster-related care needs.
    • Punitive action against non-compliant requisitioned hospitals becomes tricky during disasters since health services are already inadequate.
    • Private hospitals are known to prefer lucrative and high-end ‘cold’ cases, especially under insurance, and are generally averse to infectious diseases and critical cases with unpredictable profiles.

    Need for strong public sector capacities

    • Due to the above-cited limitations of the private sector, strong public sector capacities are imperative for dealing with disasters.
    • While the Disaster Management Act does require States and hospitals to have emergency plans, medical preparedness is a matter of policy, and, therefore, gaps are pervasive.
    • There is a strong case for introducing a legal mandate to strengthen public sector capacities via disaster legislation.
    • There is also scope for greater integration of disaster management with primary care.
    • Primary care stands for things such as multisectoral action, community engagement, disease surveillance, and essential health-care provision, all of which are central to disaster management.

    Way forward

    •  Evidence supports the significance of robust primary care during disasters, and this is particularly relevant for low-income settings.
    • Synergies with the National Health Mission, concurrently with the Disaster Management Act in 2005, could be worth exploring.
    • Interestingly, the National Health Mission espouses a greater role for the community and local bodies, the lack of which has been a major criticism of the Disaster Management Act.
    • Making primary health care central to disaster management can be a significant step towards building health system and community resilience to disasters.

    Consider the question “Robust public healthcare system is indispensable for the disaster preparedness which could be achieved through making the primary healthcare central to the disaster management. Comment.

    Conclusion

    While the novel coronavirus pandemic has waned both in objective severity and subjective seriousness, valuable messages and lessons lie scattered around. It is for us to not lose sight and pick them up.

  • State Pollution Control Boards

    The article deals with the issues faced by the State Pollution Control Boards.

    Role of CPCB and State Pollution Control Boards

    • The pollution crisis is a highly complex, multi-disciplinary issue with several contributory factors.
    • To address this crisis, India has a plethora of rules, laws and specialised agencies which, at least on paper, seem very impressive.
    • The footsoldiers of India’s battle against polluters are its officials at the state pollution control boards.
    • The Central Pollution Control Board (CPCB) based in Delhi is generally well funded and resourced, unlike the state pollution control boards (SPCBs) that are in charge of implementation of the rules that CPCB writes.

    5 issues faced by SPCBs

    1) Shortage of Staff

    • As an illustration, the Haryana State Pollution Control Board has been operating with a 70 per cent staff shortage.
    • What this means practically is that a single officer is tasked to handle the demands of pollution control for an entire district without any subordinate technical staff.
    • This comes at the cost of not being able to do inspections and other core pollution control work.

    2) Lack of specialisation

    • The officers at the SPCBs do not get to develop any specialisation.
    • The CPCB has a decent workforce and robust laboratories, where scientists once recruited get to work and excel in a particular area.
    • On the other hand, SPCBs don’t have such a stratified system, and the same officer is in charge of all these pollution categories, making it impossible to gain expertise and excel in any one area.

    3) Lack of legal skills to take on pollutors

    •  SPCBs lack the necessary legal skills to take on polluters.
    • While a legal cell may exist at the head office of a SPCB, they have few full-time public prosecutors there.
    • As a result, engineering graduates in district SPCB offices —  have to play the role of lawyers and develop legal paperwork that often falls short of holding polluters to account.
    • Clerks and superintendents at courts often refuse to file cases, pointing at flaws that someone not trained in law would naturally make.

    4) Lack of funds

    • SPCBs are chronically underfunded.
    • For instance, the funds of several SPCBs such as Haryana’s largely come from “No Objection Certificates” and “Consent to Operate” that the boards grant to industries and projects, rather than budgetary allocations by the government.
    • Owing to this, SPCB officials are unable to spend on critical functions.

    5) Additional duties

    • SPCB officials are at times given additional responsibilities that are unrelated to pollution control.
    • Haryana’s SPCB, for instance, has poultry farms under its ambit.

    Consider the question “Dealing with the crisis of air pollution need coordination at various levels and the State Pollution Control Boards play an important role in it. In light of this, examine the challenges and suggest the steps needed to empower them.”

    Conclusion

    India must empower SPCBs to act by giving them the necessary funds, human resources, tools and technologies.

  • The cost of cleaning air

    The article deals with the issue of allocation of funds to tackle air pollution and issues with it.

    Allocation in the budget

    • A â‚č4,400 crore package was announced in last budget for 2020-21 to tackle air pollution in 102 of India’s most polluted cities.
    • The funds would be used to reduce particulate matter by 20%-30% from 2017 levels by 2024 under the National Clean Air Programme (NCAP).

    Issues with estimating the scale of the problem

    • It is unclear if this amount is adequate because the scale of the problem is unknown.
    • Delhi government spent money on the measurement of pollution for in Delhi that far exceeds s allocations that find mention in the Centre and State government’s budgeting books.
    • The funds allocated don’t account for the trained manpower and the support system necessary to effectively maintain the systems and these costs are likely to be significant.
    • Historically, cites have used manual machines to measure specified pollutants and their use has been inadequate.
    • An analysis by research agencies Carbon Copy and Respirer Living Sciences recently found that only 59 out of 122 cities had PM 2.5 data available.
    • Only three States, had all their installed monitors providing readings from 2016 to 2018.
    • Prior to 2016, making comparisons of reduction strictly incomparable.
    • Now manual machines are being replaced by automatic ones and India is still largely reliant on imported machines.
    • In the case of the National Capital Region, at least â‚č600 crore was spent by the Ministry of Agriculture over two years to provide subsidised equipment to farmers in Punjab and Haryana and dissuade them from burning paddy straw.
    • Yet this year, there have been more farm fires than the previous year and their contribution to Delhi’s winter air woes remain unchanged.
    • This indicates that money alone doesn’t work.

    Conclusion

    A clear day continues to remain largely at the mercy of favourable meteorology. While funds are critical, proper enforcement, adequate staff and stemming the sources of pollution on the ground are vital to the NCAP meeting its target.

  • Glacial Lake Outburst in Ladakh

    In August 2014, a glacial lake outburst flood (GLOF) hit the village of Gya in Ladakh, destroying houses, fields and bridges. Researchers now have mapped the evolution of Gya glacial lake and note the cause of the flood.

    What is glacial lake outburst flood?

    • A GLOF is a type of outburst flood that occurs when the dam containing a glacial lake fails.
    • An event similar to a GLOF, where a body of water contained by a glacier melts or overflows the glacier, is called a Jökulhlaup.
    • The dam can consist of glacier ice or a terminal moraine.
    • Failure can happen due to erosion, a buildup of water pressure, an avalanche of rock or heavy snow, an earthquake, volcanic eruptions under the ice, or glacier collapses into it.

     How did it happen in Ladakh?

    • It was not a spillover but rather a tunnelling of drainage process that caused GLOF in Gya lake.
    • Imagine a bucket full of water. It can overflow when you drop a stone, or the water can drain if there is a hole under the bucket.
    • Similarly, here the flooding did not happen due to the spillovers due to an avalanche or landslide, rather there was a thawing of the ice cores in the moraine.

    Back2Basics: Glacial Landforms

    Glacial landforms are landforms created by the action of glacier movements.

    As the glaciers expand, due to their accumulating weight of snow and ice they crush and abrade and scour surfaces such as rocks and bedrock.  The resulting erosional landforms include striations, cirques, glacial horns, arĂȘtes, trim lines, U-shaped valleys, over-deepening and hanging valleys.

    • Cirque: Starting location for mountain glaciers
    • Cirque stairway: a sequence of cirques
    • U-shaped, or trough, valley: U-shaped valleys are created by mountain glaciers. When filled with ocean water so as to create anthe glacial action erodes through, a spillway (or col) forms
    • Valley step: an abrupt change in the longitudinal slope of a glacial valley

    When the glaciers retreated leaving behind their freight of crushed rock and sand (glacial drift), they created characteristic depositional landforms.  Examples include glacial moraines, eskers, and kames. Drumlins and ribbed moraines are also landforms left behind by retreating glaciers.

    • Esker: Built-up bed of a subglacial stream
    • Kame: Irregularly shaped mound
    • Moraine: Feature can be terminal (at the end of a glacier), lateral (along the sides of a glacier), or medial (formed by the merger of lateral moraines from contributary glaciers)
    • Outwash fan: Braided stream flowing from the front end of a glacier
