Subject: Environment

  • Elephant in the Room at COP 27- Energy Equity

    COP

    Context

    • 27th Conference of Parties (COP27, beginning November 6, in Egypt) of the United Nations Framework Convention on Climate Change (UNFCCC).

    Realization of climate action: Birth of UNFCCC

    • The idea led to the formation of the United Nations Framework for Climate Change Convention (UNFCCC, also known as ‘The Convention’) in 1992, at the Earth Summit in Rio de Janeiro.
    • The convention divided the countries on the basis of their differing commitments: Annex I and II consisted of industrialized and developed countries and Non-Annex I comprised developing countries.

    COP

    Summary of COP26

    • Inadequate reduction commitment: In the runup to COP26, last year in Glasgow, several developed countries had declared their intention to reach net zero emissions by 2050. These declarations did not square with the requirements of “keeping 1.5 deg. C alive”.
    • Global carbon budget: Four fifths of the global carbon budget to limit warming to 1.5°C (with 50% probability) has already been exhausted. Developed countries are responsible for more than half of these historical CO2 emissions. Nevertheless, there was much celebration of these targets.
    • Politics over phasing out coal: There was also high drama at COP26, with moral grandstanding by many developed country negotiators who invoked the future of their children, because India and other countries understandably balked at the singling out of any one fossil fuel for immediate action.
    • Developed countries didn’t meet the commitment: It is important to recall some of these shenanigans at COP26, as in the last year, it has become clear that developed countries may be unlikely to meet even the inadequate targets they have set, keeping to the trend of the last three decades.

    What is the present energy situation in developing countries?

    • Energy poverty concentrated in the developing countries: Global energy poverty is concentrated in the developing countries. In 2021, 733 million people had no access to electricity and almost 2.6 billion people lacked access to clean fuels and technologies.
    • The average per capita energy: Energy use of the richest 20 countries is 85 times higher than that of the 20 poorest countries. Addressing this stark energy poverty in developing countries is important because there is a strong correlation between energy supply and human development.
    • The average annual per capita electricity: Electricity consumption of sub-Saharan Africa is 487 kilowatt hours (kWh), alongside an infant mortality rate of 73 per 1,000 live births; maternal mortality ratio of 534 per 1,00,000 live births, and per capita GDP of $1,645. On the other hand, the OECD group of countries have a per capita electricity consumption of 7,750 kWh, corresponding to an infant mortality rate of seven, maternal mortality ratio of 18, and per capita GDP of $42,098.
    • Slowdown due to lack of energy: The reality of global inequality was acutely evident during the COVID19 pandemic. Several countries in Africa, Asia and Latin America are facing severe agricultural and industrial slowdowns in the post pandemic period.
    • The lack of reliable energy infrastructure: Infrastructure unavailability has compounded the difficulties and has multidimensional impacts across developmental indicators. In 2022, these inequalities have been aggravated by soaring energy and food prices.
    • Rising cost of living: Several countries face a severe rise in the cost of living and nearly 70 million additional people are estimated to fall below the poverty line of $3.20 per person per day. Poor and vulnerable communities in the energy importing countries of the global South suffer the most. Almost 90 million people in Asia and Africa, who gained access to electricity recently, cannot afford to pay their energy bills.
    • No acknowledgement of problem by developed countries: In this background, COP27 affords a critical moment to acknowledge and address the concerns surrounding energy access and security in developing countries. Unfortunately, these longstanding problems of the global South have been ignored by developed country governments, academia, and civil society. At a time when the language of energy poverty and security is re-entering the northern vocabulary, it is time to call out the hypocrisy of the advice on fossil fuel use given by the north to some of the world’s poorest regions since the Paris Agreement was signed.

    COP

    How developed countries are hypocritic about energy use and commitments?

    • Fossil fuel as primary energy source: In the United States, 81% of primary energy is from fossil fuels. In Europe, fossil fuels constitute 76% of the energy consumption (coal, oil, and natural gas contribute 11%, 31%, and 34% respectively).
    • Negligible efforts for decarbonization: Thirty years after acknowledging the problem of anthropogenic global warming and committing in the UNFCCC, to take the lead in climate change mitigation, the level of decarbonization in the global North has been minuscule.
    • Increasing coal consumption: In July 2022, the European Union (EU) voted to classify the use of natural gas for some uses as “green and sustainable”. Natural gas was responsible for 7.5 billion tonnes of CO2 (i.e., 23% of the total CO2 by the major fossil fuels), in 2020. Additionally, in 2022, even coal consumption in the U.S. and the EU is estimated to increase by 3% and 7%, respectively.
    • Double standard for fossil fuel: These same developed countries argue that green energy constitutes a great business opportunity for developing countries as it has become cheaper. They have used this dubious argument to dismiss differentiation between developed and developing countries and are lobbying for banning the financing of any fossil fuel projects in some of the poorest countries.

    What should be the agenda of developing countries at COP 27?

    • Bring the energy poverty issue: At COP27, the global South must put the question of its energy poverty and the severe global inequalities in energy access squarely at the Centre of all discussions.
    • Achieving SDGs with climate actions: We need to achieve zero hunger, zero malnutrition, zero poverty, and universal wellbeing even as we collectively contribute to ensuring effective climate action.
    • No empty commitments: As the strapline for COP27 (“Together for Implementation”) suggests, we must work together to ensure that these developmental goals are not side-lined, as they were at COP26, in the pursuit of hollow declarations of net zero targets three decades into the future.

    COP

    Conclusion

    • A developing country leadership at COP27 can ensure effective discussions, based on equity and common but differentiated responsibilities and respective capabilities, on the relative responsibilities and sharing of mitigation and adaptation burdens while coping with loss and damage.

  • LT-LEDS (Long Term-Low Emission Development Strategy)

    strategy

    India has announced its long-term strategy to transition to a “low emissions” pathway at the United Nations Conference of Parties (COP) ongoing in Sharm el-Sheikh, Egypt.

    What are LT-LED Strategy?

    • The LT-LEDS are qualitative in nature and are a requirement emanating from the 2015 Paris Agreement.
    • Hereby, countries explain how they will transition their economies beyond achieving near-term NDC targets.
    • It signifies their path towards the larger climate objective of cutting emissions by 45% by 2030 and achieve net zero around 2050.

    BACKGROUND

    What is the meaning of Net Zero?

    • A state in which a country’s emissions are compensated by absorption and removal of greenhouse gases (GHGs) from the atmosphere is called Net Zero State; it is also referred to as carbon-neutrality.
    • It is done through natural processes as well as futuristic technologies such as carbon capture and storage.

    Nationally Determined Contributions (NDCs): 

    • To achieve the targets under the agreement, the member countries must submit the targets themselves, which they believe would lead to substantial progress towards reaching the Paris temperature goal.
    • Initially, these targets are called Intended Nationally Determined Contributions (INDCs).
    • They are converted to NDCs when the country ratifies the agreement.

    Key announcements by India

    • Nuclear energy: India is set to expand its nuclear power capacity by at least three-fold in the next decade.
    • Green hydrogen: India aims for becoming an international hub for producing green hydrogen through the National Hydrogen Mission.
    • Ethanol blending: India aspires to maximise the use of electric vehicles, with ethanol blending to reach 20% by 2025 (it is currently 10%) and a “strong shift” to public transport for passenger and freight traffic.
    • Energy efficiency: India will also focus on improving energy efficiency by the Perform, Achieve and Trade (PAT) scheme.
    • Carbon sequestration: India’s forest and tree cover are a net carbon sink absorbing 15% of CO2 emissions in 2016, and it is on track to fulfilling its NDC commitment of 2.5 to 3 billion tonnes of additional carbon sequestration in forest and tree cover by 2030.

    Hurdles in achieving net-zero

    • Huge cost of transition: The transition to low carbon pathway will entail several costs amounting to several trillion dollars. It involves the development of new technologies, new infrastructure, and other transaction costs.
    • No climate finance mechanism: Provision of climate finance by developed countries will play a very significant role and needs to be considerably enhanced.

    Significance of India’s LTS

    • India’s long-term strategy (LTS) follows up on the net zero pledge.
    • It clearly outlines key interventions across sectors that are going to be the focus of India’s efforts.

    Considerations made by India

    India’s approach is based on the following four key considerations that underpin its long-term low-carbon development strategy:

    1. India has contributed little to global warming: its historical contribution to cumulative global GHG emissions being minuscule despite having a share of ~17% of the world’s population.
    2. Huge domestic energy demand: India has significant energy needs for development.
    3. National circumstances: India is committed to pursuing low-carbon strategies for development and is actively pursuing them, as per national circumstances
    4. India needs to build climate resilience: It is the capacity of social, economic and ecosystems to cope with a hazardous event or trend or disturbance.

  • Places in news: Sahel Region

    sahel

    French President Emmanuel Macron announced the end of the decade-long Operation Barkhane in Africa’s Sahel Region.

    Note the nations falling in Sahel Region.

    Sahel Region

    • The Sahel is the ecoclimatic and biogeographic realm of transition in Africa between the Sahara to the north and the Sudanian savanna to the south.
    • Having a semi-arid climate, it stretches across the south-central latitudes of Northern Africa between the Atlantic Ocean and the Red Sea.
    • The name is derived from the Arabic term for “coast, shore”; this is explained as being used in a figurative sense in reference to the southern edge of the vast Sahara.
    • The Sahel part includes from west to east parts of northern Senegal, southern Mauritania, central Mali, northern Burkina Faso, the extreme south of Algeria, Niger, the extreme north of Nigeria, the extreme north of Cameroon and the Central African Republic, central Chad, central and southern Sudan, the extreme north of South Sudan, Eritrea and the extreme north of Ethiopia.

    What is Operation Barkhane?

    • France began its military operations in Sahel in January 2013.
    • Titled Operation Serval, it was limited to targeting Islamic extremists linked to al-Qaeda who took control of northern Mali.
    • However, in 2014, the mission was scaled up, renamed Operation Barkhane and was aimed at counter-terrorism.
    • The objective was to assist local armed forces to prevent the resurgence of non-state armed groups across the Sahel region.
    • Around 4,500 French personnel were deployed with the local joint counter-terrorism force.

  • Mangrove Alliance for Climate (MAC) launched at COP27

    mangroves

    At the 27th Session of the Conference of Parties (COP27), this year’s UN climate summit, the Mangrove Alliance for Climate (MAC) was launched with India as a partner.

    Mangrove Alliance for Climate (MAC)

    • An initiative led by the UAE and Indonesia, the MAC includes India, Sri Lanka, Australia, Japan, and Spain.
    • It seeks to educate and spread awareness worldwide on the role of mangroves in curbing global warming and its potential as a solution for climate change.
    • Under MAC, UAE intends to plant 3 million mangroves in the next two months, in keeping with UAE’s COP26 pledge of planting 100 million mangroves by 2030.

    Working of MAC

    • MAC would work on a voluntary basis. It means that there are no real checks and balances to hold members accountable.
    • Instead, the parties will decide their own commitments and deadlines regarding planting and restoring mangroves.
    • The members will also share expertise and support each other in researching, managing and protecting coastal areas.

    Why protect mangroves?

    • Infrastructure projects — industrial expansion, shifting coastlines, coastal erosion and storms, have resulted in a significant decrease in mangrove habitats.
    • Between 2010 and 2020, around 600 sq km of mangroves were lost of which more than 62% was due to direct human impacts, the Global Mangrove Alliance said in its 2022 report.

    Importance of mangroves

    mangrove

    • Biodiversity: Mangrove forests — consisting of trees and shrub that live in intertidal water in coastal areas — host diverse marine life.
    • Fishing grounds: They also support a rich food web, with molluscs and algae-filled substrate acting as a breeding ground for small fish, mud crabs and shrimps, thus providing a livelihood to local artisanal fishers.
    • Carbon sinks: Equally importantly, they act as effective carbon stores, holding up to four times the amount of carbon as other forested ecosystems.
    • Cyclone buffers: When Cyclone Amphan struck West Bengal in May, its effects were largely mitigated by the Sundarbans flanking its coasts along the Bay of Bengal.

    Threats to Mangroves

    • Anthropogenic activities: They are a major threat to the mangroves. Urbanization, industrialization and the accompanying discharge of industrial effluents, domestic sewage and pesticide residues from agricultural lands threaten these fragile ecosystems.
    • Saltpan and aquaculture: This causes huge damage to the mangroves. Shrimp farming alone destroyed 35,000 hectares of mangroves worldwide.
    • Destruction for farming: 40% of mangroves on the west coast has been converted into farmlands and other settlements in just 3 decades.
    • Sea-level rise: This is another challenge to these mangroves- especially on the Bay of Bengal coast.

    Mangroves in India

    • India holds around 3 percent of South Asia’s mangrove population.
    • Besides the Sundarbans in West Bengal, the Andaman region, the Kutch and Jamnagar areas in Gujarat too have substantial mangrove cover.

    How can India benefit from MAC?

    • India is home to one of the largest remaining areas of mangroves in the world — the Sundarbans.
    • It has years of expertise in restoration of mangrove cover that can be used to aid global measures in this direction.
    • The move is in line with India’s goal to increase its carbon sink.

    Q.Which one of the following is the correct sequence of ecosystems in the order of decreasing productivity?

    (a) Oceans, lakes, grasslands, mangroves

    (b) Mangroves, oceans, grasslands, lakes

  • Energy Transition Accelerator (ETA): A new carbon offset scheme by the US

    eta

    The US has unveiled a new carbon offset scheme called Energy Transition Accelerator (ETA) for climate finance.

    Energy Transition Accelerator (ETA)

    • ETA is carbon offset plan that will allow companies to fund clean energy projects in developing countries and gain carbon credits that they can then use to meet their own climate goals.
    • The plan will be developed by the US along with the Bezos Earth Fund and the Rockefeller Foundation.
    • It would receive inputs from public and private
    • The concept is to put the carbon market to work, deploy capital otherwise undeployable, and speed up the transition from dirty to clean power.

    Benefits of ETA

    • It may be good for renewable energy projects for sure and for those coal plants that are very old and unviable and which India wishes to shut down.
    • The scheme comes at a time when there is growing mistrust among developing countries about developed nations failing to deliver on climate finance commitments.

    Limitations of ETA

    • The proposed initiative would be insufficient to make up for the lack of funding from rich countries.
    • What developing countries need is predictable finance – not offset markets.
    • The proposed initiative cannot make up for the US’s failure to provide its fair share of climate finance – an estimated $40 billion of the unmet goal of $100 billion a year.

    Conclusion

    • ETA appears to be a substitute for deep decarbonization needed within the US and other industrialized countries.
    • For developing countries like India, the first priority would be to meet their own targets and not provide offsets for reductions in developed nations.

  • Urban Pollution

    Urban Pollution

    Context

    • More than 1,10,000 infants are likely to have been killed by air pollution in India in 2019, almost immediately after being born while long-term exposure to outdoor and household air pollution was estimated to be responsible for about 1.67 million annual deaths amongst the adult population in the country.

    What is pollution?

    • Pollution is the introduction of harmful materials into the environment. These harmful materials are called pollutants. Pollutants can be natural, such as volcanic ash. They can also be created by human activity, such as trash or runoff produced by factories. Pollutants damage the quality of air, water, and land.

    Urban Pollution

    Menace of air pollution in urban areas

    • Demands for air purifiers: Demand for air purifiers has boomed. Recently, in Delhi, pollution-related curbs were lifted and schools opened, despite air quality continuing to be in the “very poor” category.
    • Health related problems: For the majority of urban north Indians who can’t afford air purifiers, life continues amidst dust, cough and breathlessness.
    • Children are most affected: Our children in urban localities are growing up with stunted lungs, amidst poverty.
    • High percentage of respiratory problems: Eighty per cent of all families in Delhi are noted to be suffering respiratory ailments due to severe pollution.

    How we can reduce the air pollution?

    • Expand green cover across urban areas to reduce dust pollution: Ahmedabad’s municipal corporation, for instance, has experimented with urban forests, with the city’s 43rd urban forest inaugurated in June 2021 over 20,000 trees have been in 7,625 sq. metres. Chandigarh has about 1,800 parks. Close to 46 per cent of the city was classified as a green area in 2019.
    • Use of Miyawaki technique: Civil society could also help in Chennai, the NGO Thuvakkam, with a volunteer force of 1,800, has been able to grow 25 Miyawaki forests, raising over 65,000 trees. Such plantations are now being replicated in other cities including Tuticorin, Vellore and Kanchipuram.
    • Push for airshed management: With a focus on understanding meteorological, seasonal and geographic patterns for air quality across a large region. In the US, the passage of the Air Quality Act (1967) saw the state of California being divided into 35 districts which had similar geographic and meteorological conditions and pollution was regulated at the state level. This approach was successful in reducing emissions by 98 per cent from 2010 to 2019.
    • Heavy penalty on polluting cars: Inspiration can also be taken from London’s air pollution revolution an Ultra-Low Emission zone has been established in Central London, with hefty daily fees on cars that emit more than 75g/km of pollution.

    Urban Pollution

    Water pollution in Indian cities

    • Untreated water into freshwater bodies: 72 per cent of urban sewage is untreated in India’s urban freshwater bodies. The Central Pollution Control Board reckons that more than 50 per cent of 351 river stretches (on 323 rivers) are polluted. Over 4,000 septic trucks (with each truck having 5,000 litres of human waste) dispose of their waste in the Ganga every day. In Delhi, about 941 MLPD of raw sewage finds its way to the river, killing off fish and preventing rituals on the banks.
    • Riverine Pollution: Riverine pollution causes due to raw sewage overflowing from sewage treatment plants, untreated waste from unauthorized colonies, industrial effluents, sewer water from authorized colonies and inter-state pollution.
    • Water scarcity: More than 40 per cent of Indians are expected to face water scarcity by 2050 and close to 35 million will face annual coastal flooding with sea level rise.
    • Lack of planning: Apathy prevails as of May 2021, only 16 Indian cities had disclosed their plans to tackle climate change to international institutions, with only eight having actual sustainability-related targets in their urban master plans. Only 43 per cent of all Indian cities surveyed actually sought to address climate change adaption as a topic in their master plans, while only five had a GHG emission reduction target.

    Urban Pollution

    Do you know this harsh reality?

    • In India, nearly 7 lakh premature deaths are attributed to water pollution
    • Globally, 1.5 million children under five years die each year as a result of water-related diseases.

    How to fight water pollution?

    • Improving sewage treatment plant capacity: ensuring linkages with the drainage network. Mangalore’s City Corporation (MCC) has wastewater treatment plants with end-user linkages. The MCC offered to supply treated water to such industrial end-users in the city’s special economic zone if the latter agreed to fund about 70 per cent of the operations and maintenance cost of the pumps and the sewage treatment plant.
    • Developing a sanitation network: The problem of untreated waste and sewer water from unauthorized colonies can be solved by investing in a sewerage network. Consider the example of Alandur, a small suburb of Chennai in 2000, it had no underground sewage lines, with most houses dependent on septic tanks. In the late 1990s, the local municipality in partnership with local resident welfare associations conducted collection drives to gain deposits (ranging from Rs 1,000 to Rs 1,500) for developing a sanitation network.
    • Pump house: The project was launched with a push for creating a pump house, setting up over 5,650 manholes and providing sewerage connections to 23,700 households, a sewage treatment plant with a 12 MLD capacity was also set up. Going forward, many other municipalities in Tamil Nadu have sought to adopt this model.
    • A systems-based approach should be adopted: along with a push for protecting “blue infra” areas places that act as natural sponges for absorbing surface runoff, allowing groundwater to be recharged. At the household level, we can encourage citizens to take up rainwater harvesting, urban roof terrace greening, urban roof water retention tanks and having a green corridor around residential buildings.
    • Water permeable roads: Municipalities could be encouraged to make existing roads permeable with a push for green landscaping and rain gardens. At the city level and beyond, policymakers should push for “sponge cities” and incorporate disaster planning. A mindset shift, in citizenry and policymakers, is urgently needed.

    Conclusion

    • Urban planning and urban pollution are largely neglected in our governance model. Unplanned cities are facing the various problems. We must embrace the technology to fight the pollution in urban India.

    Mains Question

    How severe is the problem of Urban pollution? What steps can be taken to fight the urban pollution in India?

  • Groundwater Extraction Lowest in 18 years

    groundwater

    Groundwater extraction in India saw an 18-year decline, according to an assessment by the Central Ground Water Board (CGWB).

    What is Groundwater?

    groundwater

    • Groundwater is the water found underground in the cracks and spaces in soil, sand and rock.
    • It is stored in and moves slowly through geologic formations of soil, sand and rocks called aquifers.
    • Aquifers are typically made up of gravel, sand, sandstone, or fractured rock, like limestone.
    • Water can move through these materials because they have large connected spaces that make them permeable.
    • Aquifers, hand-dug wells, and artesian wells are different types of sources of groundwater.

    Declining trend of groundwater extraction

    • The total annual groundwater recharge for the entire country is 437.6 billion cubic metres (bcm) in 2022.
    • However the extraction for entire country is only 239.16 bcm, according to the 2022 CGWB report.
    • By comparison, an assessment in 2020 found that the annual groundwater recharge was 436 bcm and extraction 245 bcm.
    • The 2022 assessment suggests that groundwater extraction is the lowest since 2004, when it was 231 bcm.

    Implications of the CGWB report

    • A detailed analysis of the assessment indicates increase in ground water recharge.
    • This is mainly attributed to:
    1. Increase in recharge from canal seepage,
    2. Return flow of irrigation water and
    3. Recharges from water bodies/tanks & water conservation structures.

    Significance of groundwater

    • Groundwater supplies drinking water to a sizeable population in India and almost 99% of the rural population.
    • It helps grow our food. 64% of groundwater is used for irrigation to grow crops.
    • It is an important component in many industrial processes.
    • It is a source of recharge for lakes, rivers, and wetlands.

    Why discuss this?

    • Depletion: People face serious water shortages because groundwater is used faster than it is naturally replenished.
    • Contamination: In other areas groundwater is polluted by human activities.

    Reasons for Depletion

    • Increased demand for water for domestic, industrial and agricultural needs and limited surface water resources lead to the over-exploitation of groundwater resources.
    • Limited storage facilities owing to the hard rock terrain, along with the added disadvantage of lack of rainfall, especially in central Indian states.
    • Green Revolution enabled water-intensive crops to be grown in drought-prone/ water deficit regions, leading to over-extraction of groundwater.
    • Frequent pumping of water from the ground without waiting for its replenishment leads to quick depletion.
    • Subsidies on electricity and high MSP for water-intensive crops is also leading reasons for depletion.
    • Inadequate regulation of groundwater laws encourages the exhaustion of groundwater resources without any penalty.
    • Deforestation, unscientific methods of agriculture, chemical effluents from industries, and lack of sanitation also lead to pollution of groundwater, making it unusable.
    • Natural causes include uneven rainfall and climate change that are hindering the process of groundwater recharge.

    Impact of groundwater depletion

    • Lowering of the water table: Groundwater depletion may lower the water table leading to difficulty in extracting groundwater for usage.
    • Reduction of water in streams and lakes: A substantial amount of the water flowing in rivers comes from seepage of groundwater into the streambed. Depletion of groundwater levels may reduce water flow in such streams.
    • Subsidence of land: Groundwater often provides support to the soil. When this balance is altered by taking out the water, the soil collapses, compacts, and drops leading to subsidence of land.
    • Increased cost for water extraction: As the depleting groundwater levels lower the water table, the user has to delve deep to extract water. This will increase the cost of water extraction.

    Regulation of Groundwater in India

    (1) Central Ground Water Authority (CGWA)

    • It has the mandate of regulating ground water development and management in the country.
    • It is constituted under the Environment (Protection) Act of 1986.
    • CGWA issues advisories, public notices and grant No Objection Certificates (NOC) for ground water withdrawal.

    (2) National Aquifer Mapping and Management Programme (NAQUIM)

    • The NAQUIM is an initiative of the Ministry of Jal Shakti for mapping and managing the entire aquifer systems in the country.
    • It maintains the Hydrological Map of India.

    (3) Atal Bhujal Yojana 

    • It is a Central Sector Scheme, for sustainable management of groundwater resources with community participation in water-stressed blocks.

    Way Forward

    • Routine survey: There should be regular assessment of groundwater levels to ensure that adequate data is available for formulating policies and devising new techniques.
    • Assessment of land use pattern: Studies should be carried out to assess land use and the proportion of agricultural land falling under overt-exploited units.
    • Changes in farming methods: To improve the water table in those areas where it is being overused, on-farm water management techniques and improved irrigation methods should be adopted.
    • Reforms in power supply subsidies: The agricultural power-pricing structure needs to be revamped as the flat rate of electricity adversely affects the use of groundwater.
    • Monitoring extraction: There should be a policy in place to monitor the excessive exploitation of groundwater resources to ensure long-term sustainability.

  • Genesis of the Delhi Air Pollution and its mitigation

    delhi

    As the situation becomes an annually recurring one in New Delhi and NCR, here’s a look at how far back it goes and what policies have been adopted by the Centre and Delhi’s elected governments to curb air pollution over the years.

    In November 2016, in an event known as the Great Smog of Delhi, the air pollution spiked far beyond acceptable levels. This tagged New Delhi to be world’s most polluted city ever.

    Causes of Poor Air Quality

    • Motor vehicle emissions are one of the causes of poor air quality.
    • Badarpur Thermal Power Station, a coal-fired power plant was another major source of air pollution in Delhi.
    • The drift/mist emissions from the wet cooling towers are also a source of particulate matter as they are widely used in industry and other sectors for dissipating heat in cooling systems.
    • Although Delhi is kerosene free and 90% of the households use LPG for cooking, the remaining 10% uses wood, crop residue, cow dung, and coal for cooking. (Census-India, 2011)
    • Fires in Bhalswa landfill is a major reason for airborne particles in Delhi.
    • Burning of effigies during Vijayadashami and bursting of firecrackers burning during Diwali is often accused by the left-wing activists to cause of Delhi’s poor air quality.
    • Agricultural stubble burning in Haryana and Punjab, coupled with north-westerly winds also affects Delhi’s air quality since the 1980s when crops are being harvested.

    Evolution of policies

    (1) Recognition of the broader issue (1995)

    • In March 1995, the Supreme Court, while hearing a plea by environmentalist and lawyer M.C. Mehta about Delhi’s polluting industries
    • It noted that Delhi was the world’s fourth most polluted city in terms of concentration of suspended particulate matter (SPM) in the ambient atmosphere as per the WHO’s 1989 report.

    (2) Identifying major pollutants (1996)

    • The Court took note of two polluting factors — vehicles and industries.
    • In 1996, the court ordered the closure and relocation of over 1,300 highly-polluting industries from Delhi’s residential areas beyond the National Capital Region (NCR) in a phased manner.
    • In 1996, Mr. Mehta filed another public interest litigation (PIL) alleging that vehicular emissions were leading to air pollution and that it posed a public health hazard.

    (3) Action plan by Delhi Govt. (1996)

    • The Delhi government submitted an action plan to the apex court.
    • The court recognised the need for technical assistance and advice in decision-making and implementation of its orders.

    (4) Establishment of EPCA (1998)

    • The Supreme Court asked the Environment Ministry to establish an authority for Delhi, leading to the creation of the Environmental Pollution Control Authority of Delhi NCR (EPCA) in 1998.
    • The EPCA submitted its report containing a two-year action.
    • The Court subsequently ordered the Delhi Transport Corporation (DTC) bus fleet, taxis, and autos to switch to Compressed Natural Gas (CNG), and the phasing out of all pre-1990 autos.
    • Coal-based power plants within Delhi were also converted to gas-based ones.

    (5) National Air Quality Programme (NAMP)

    • Around the same time, the Centre decided to establish a network of monitoring stations under the National Air Quality Programme (NAMP) to measure key pollutants.
    • The NAMP monitors the four major pollutants as part of the AQI – sulphur dioxide, oxides of nitrogen, respirable particulate matter and fine particulate matter.
    • It also checks wind speed and direction along with relative humidity and temperature.

    How were air quality standards revised?

    • The National Ambient Air Quality Standards (NAAQS) were specified by the Central Pollution Control Board (CPCB).
    • It identified pollutants like PM10 (particulate matter with a diameter exceeding 10 microns), sulphur dioxide and nitrogen oxides were measured.
    • The NAAQS were revised in 2009 to include 12 categories of pollutants including PM2.5 (particulate matter with a diameter under 2.5 microns
    • Particulate Matter (PM) is primarily generated by fuel combustion from different sectors, including transport, energy, households, industry and agriculture.

    Arriving finally at: Graded Response Action Plan (GRAP)

    • According to the revised NAAQS, the acceptable annual limit for PM2.5 is 40 micrograms per cubic metre (ug/m3) and 60 ug/m3 for PM10.
    • In the winter of 2016, Delhi witnessed one of its worst incidents of pollution-induced smog, with PM2.5 and PM10 levels reaching a whopping 999 ug/m3 in parts of Delhi on November 1.
    • Subsequently, the Supreme Court in November 2016 told Delhi and NCR authorities to form a plan to deal with the air pollution.
    • The MoEFCC in early 2017 came out with the Graded Response Action Plan (GRAP).

    Q.Mumbai, Delhi and Kolkata are the three megacities of the country but the air pollution is a much more serious problem in Delhi as compared to the other two. Why is this so?

  • Species in news: Snow Leopard

    leopard

    The first-ever recording of the snow leopard from the Baltal-Zojila region has renewed the hope for the elusive predator in the higher altitudes of Jammu and Kashmir and Ladakh.

    Why in news?

    • Not much is known about the number of snow leopards in J&K and Ladakh.
    • The Snow Leopard Population Assessment of India (SPAI) has been concluded so far in Himachal Pradesh and Uttarakhand.
    • The estimated population of the great cat is 50 and 100 in these two States respectively.

    Snow Leopard

    • Snow leopards live in the mountainous regions of Central and Southern Asia.
    • In India, their geographical range encompasses a large part of the western Himalayas, including the UTs of J&K and Ladakh, Himachal Pradesh, Uttarakhand and Sikkim and Arunachal Pradesh in the eastern Himalayas.
    • Project Snow Leopard was launched in 2009 for strengthening wildlife conservation in the Himalayan high altitudes.
    • It aims at promoting a knowledge-based and adaptive conservation framework that fully involves the local communities, who share the snow leopard’s range, in conservation efforts.

    Conservation status

    • In the IUCN- Red List, the snow leopard is listed as Vulnerable.
    • In addition, the snow leopard, like all big cats, is also listed in Appendix I of the Convention on International Trade of Endangered Species (CITES).
    • In India, the snow leopard is listed under Schedule I of the Wildlife (Protection) Act, 1972, giving it the highest protection status under the country’s laws.

    Conservation Efforts by India

    • The Government of India has identified the snow leopard as a flagship species for the high altitude Himalayas.
    • India is also party to the Global Snow Leopard and Ecosystem Protection (GSLEP) Programme since 2013.
    • HimalSanrakshak: It is a community volunteer programme, to protect snow leopards, launched in October 2020.
    • In 2019, First National Protocol was also launched on Snow Leopard Population Assessment which has been very useful for monitoring populations.
    • SECURE Himalaya: Global Environment Facility (GEF)-United Nations Development Programme (UNDP) funded the project on conservation of high altitude biodiversity and reducing the dependency of local communities on the natural ecosystem.
    • Project Snow Leopard (PSL): It was launched in 2009 to promote an inclusive and participatory approach to conserve snow leopards and their habitat.
    • Snow Leopard is on the list of 21 critically endangered species for the recovery programme of the Ministry of Environment Forest & Climate Change.
    • Snow Leopard conservation breeding programme is undertaken at Padmaja Naidu Himalayan Zoological Park, Darjeeling, West Bengal.

    Global Snow Leopard and Ecosystem Protection (GSLEP) Programme

    • The GSLEP is a high-level inter-governmental alliance of all the 12 snow leopard range countries.
    • The snow leopard countries namely, India, Nepal, Bhutan, China, Mongolia, Russia, Pakistan, Afghanistan, Kyrgyzstan, Kazakhstan, Tajikistan, and Uzbekistan.
    • It majorly focuses on the need for awareness and understanding of the value of Snow Leopard for the ecosystem.
