Methane Mitigation to Combat Global Warming

In News: Recently, the International Energy Agency, the United Nations Environment Programme (UNEP), and the UNEP-convened Climate and Clean Air Coalition have jointly released a report titled "The Imperative of Cutting Methane from Fossil Fuels" highlighting the significance of targeted methane mitigation to combat global warming. 

Key Highlights of the Report: 

  • Methane Emissions and Global Warming: To keep global warming to 1.5°C over pre-industrial levels, methane emissions must be reduced. Methane is a very strong greenhouse gas that has been contributing to global warming since the Industrial Revolution at a rate of roughly 30%. By 2050, these initiatives could be able to stop global warming by about 0.1°C. 
  • Present Methane Emission Scenario: Methane emissions total about 580 million tonnes annually throughout the world. 60% of these emissions are a result of human activity. About 120 million tonnes of methane emissions in 2022 came from fossil fuel activities alone. Total anthropogenic methane emissions might increase by up to 13% between 2020 and 2030 if current trends continue. 
  • Target Methane Mitigation: Even with significant reductions in fossil fuel consumption, failure to manage methane might cause global temperatures to rise over 1.6°C by 2050. Measures to specifically reduce methane are essential and should support decarbonization efforts. By 2030, nearly 80 million tonnes of methane emissions from fossil fuels can be avoided according to current technology. 
  • In the Net Zero scenario, all methane reduction initiatives in the oil and gas sector will cost around USD 75 billion by 2030. The majority of initiatives can and should be funded by the industry, but some interventions may be impossible to undertake in low- and middle-income nations without special financing because of access issues. 
  • Economic and Health Benefit: Ground-level ozone pollution is mostly caused by methane, and mitigation measures will reduce the number of premature deaths by "nearly one million through 2050, which is equivalent to the current population of Amsterdam, Netherlands." 95 million tonnes of agricultural losses for wheat, rice, soy, and maize (corn) will be avoided if methane reduction goals are accomplished. 
  • By 2020 to 2050, preventing such losses of crops, labor, and forests will "provide direct economic benefits valued at more than USD 260 billion." 

United Nations Environment Programme (UNEP): 

  • The UNEP is a leading global environmental authority established on 5th June 1972. 
  • Headquarters: Nairobi, Kenya. 
  • Major Reports: Emission Gap Report, Adaptation Gap Report, Global Environment Outlook, Frontiers, Invest into Healthy Planet. 
  • It establishes the global environmental agenda, advances sustainable development within the framework of the United Nations, and acts as a strong voice for the defence of the environment worldwide. 
  • India is a member of the UNEP. 

UNEP-Convened Climate and Clean Air Coalition (CCAC): 

  • Governments, international organisations, corporations, academic institutions, and civil society organisations are participating in a voluntary worldwide collaboration to eliminate short-lived climate pollutants (SLCPs), which have a substantial impact on public health and climate change. 
  • Since 2019, India has become a CCAC Partner. 

International Energy Agency: 

  • It is an independent intergovernmental organisation that was founded in Paris, France, in 1974. 
  • It primarily focuses on its energy policy, which include environmental preservation, economic growth, and energy security. 
  • Major Reports: World Energy Outlook Report, World, Energy Investment Report, and India Energy Outlook Report. 
  • India joined the IEA in 2017. 


  • The simplest hydrocarbon, methane (CH4), is made up of just one carbon atom and four hydrogen atoms. It is combustible and used as fuel all around the world. 
  • Methane is a powerful greenhouse gas (GHG) with an atmospheric lifespan of around ten years and long-term effects on climate.

Bio-Decomposer to Address Stubble Burning

In News: Recently, the Delhi Government has initiated the spraying of a Bio-Decomposer to tackle Stubble Burning. 

Stubble Burning: 

  • The process of burning straw stubble that remains after the harvest of grains such as rice, wheat, etc. is known as stubble burning. It is typically necessary in regions where agricultural residue is left behind after combination harvesting. 
  • Throughout North West India, it is a custom throughout October and November, although it is most prevalent in Punjab, Haryana, and Uttar Pradesh. 
  • The paddy crop residues are removed from the field to sow wheat from the last week of September to November, coinciding with the withdrawal of Southwest Monsoon. 

Impacts of Stubble Burning: 

  • It emits a significant quantity of carcinogenic polycyclic aromatic hydrocarbons, volatile organic chemicals, methane (CH4), carbon monoxide (CO), and other hazardous gases into the environment. 
  • The nutrients in the soil are destroyed when husk is burned on the ground, making the soil less fertile. 
  • The soil loses moisture and beneficial bacteria as a result of the heat produced by burning stubble. 

Alternatives to Stubble Burning: 

  • In-Situ Treatment: Crop residue management by zero-tiller machine and Use of bio-decomposers. 
  • Ex-Situ Treatment: Use of rice straw as cattle fodder. 
  • Application of Technology: Stubble can be uprooted and seeds can be sown in the cleaned area using the Turbo Happy Seeder (THS) equipment. The field can then be mulched using the leftover stubble. 

Use of Bio – Decomposer: 

  • In the application of Bio – Decomposer, a variety of microorganisms, including fungus, bacteria, and enzymes, work together to decompose plant matter into organic matter, which enriches the soil. 
  • The goal of a bio decomposer is to accelerate the natural breakdown of agricultural wastes. 
  • Pusa - Bio decomposer: 
    • It is a fungi-based liquid solution that can soften hard stubble to the extent that it can be easily mixed with soil in the field to act as compost. 
    • It is developed by the Indian Council of Agricultural Research (ICAR). 
    • The fungi thrive at 30oC-32oC. 
  • Benefits: 
    • The decomposer increases the soil's fertility and production since the stubble serves as compost and manure for the crops, requiring less fertiliser in the future. 
    • It is a realistic method to eliminate stubble burning that is also effective, affordable, practicable, and practical. 
    • It is a green technology that benefits the environment and will help realise the Swachh Bharat Mission. 
  • Applicability: 
    • The stubble has to be sprayed after harvest, ploughed into the ground, and moderately watered for a period of 20 to 25 days for it to break down. 
    • Crop rotation, labour availability, and the type of crop farmed all have an impact on the decomposer's applicability to farmers. 
    • The application of the microbial solution is favoured in September and October because of the lower rainfall during those months. 

Way Forward: 

  • Encourage farmers to use alternative agricultural methods including direct sowing, zero tillage, and crop diversification. These techniques may reduce the production of agricultural residue and the requirement for burning stubble. 
  • Encourage the use of cutting equipment that can cut crops at a lower height, leaving less stubble behind, such as combine harvesters. Due of this, less stubble will need to be burned. 
  • Run awareness initiatives to inform farmers of the risks of stubble burning and the alternatives available. To successfully communicate knowledge, engage with farmer organisations, agricultural universities, and local communities.

Estivation/ Aestivation - Edukemy Current Affairs

In News: Estivation: The summer’s urge to nap 


  • Estivation is a biological occurrence wherein certain animals enter an extended state of dormancy or inactivity as a response to hot and arid environmental conditions.  
  • This serves as an essential survival tactic aimed at preserving both energy and water resources.  
  • Animals undergoing estivation typically find refuge in underground burrows, crevices, or protective cocoons, which allows them to minimize their metabolic processes and energy expenditure.  
  • This behavioral adaptation is crucial for preventing desiccation and reducing the vulnerability to predation. Some examples of animals that employ estivation as a strategy include the West African lungfish, desert tortoises, and specific land snail species.,water%20in%20a%20difficult%20time.

Increase in Glacial lake outburst flood (GLOF) in India

Exam View: The Sikkim story; Glacial lake outburst flood (GLOF); Glacial Lake atlas; Way forward. 

Context: India has witnessed at least three highly devastating GLOF events in the Ganga and Brahmaputra basins over the last decade that include the ones at Kedarnath in 2013, Chamoli in 2021 and Sikkim in 2023. 

Decoding the editorial: The Sikkim story 

  • The southern bank of the South Lhonak Lake in Sikkim burst open, leading to an outflow of huge amounts of water.  
    • Since the lake region is too remote and has scarcely any monitoring network, the exact cause of this glacial lake outburst flood (GLOF) is not known yet. 
  • Damages: 
    • The floods caused heavy damage to the Chungthang Dam and hydropower projects of NHPC.  
    • More than 35 people were killed. 
    • 14 bridges were washed away or submerged.  
    • 1,320 houses were severely damaged.  
    • Drinking water supply lines and sewage networks were damaged. 
    • Widespread damage to highways was reported in North Sikkim, Gangtok, Pakyong, and Namchi districts. The floods damaged sections of National Highway 10, connecting Sikkim with the rest of India. 

Glacial lake outburst flood (GLOF) 

  • Glacial lakes are formed near the snout of glaciers when meltwater accumulates.  
    • In recent times, such lakes have been forming with increased frequency because the increased warming of the troposphere has glacier melting.  
    • The embankments of these lakes consist of loose deposits of glacier moraine, rocks, boulders, soil and ice.  
    • Since these embankments are not properly compacted, they have a high vulnerability quotient.  
  • Floods occur when these embankments fail in certain situations: 
    • The lake water level rises rapidly due to intense rainfall or 
    • A portion of the glacier is detached from the main body and plunges into the lake, generating high waves. These waves could hit the embankment forcefully.  
    • Earthquakes destabilise the embankment and water seeping in through the embankment could cause erosion. 

Glacial lake atlas 

  • The ISRO’s National Remote Sensing Centre (NSCRC) released a glacial lake atlas of the Himalayan River Basins.  
    • NRSC used images acquired by RESOURCESAT-2 satellite during 2016-17 to prepare this atlas, which has identified more than 28,000 glacial lakes of more than 0.25 ha. 
    • Catchments of the three river basins in north and northeast India have a large number of glacial lakes.  
  • In a widely quoted scientific paper in Nature Communications, the authors concluded that more than nine million people in High Mountain Asia (HMA), are vulnerable to glacial lake outbursts 
  • The Sikkim State Disaster Management Authority has identified more than 300 glacial lakes in the state. Of these, 10 have been identified as vulnerable to outburst floods.  
  • The Geological Survey of India has found that 13 of the 486 glacial lakes in Uttarakhand are vulnerable to GLOFs.  
  • A 2021 study led by Delhi University scientist Suraj Mal reported that Jammu and Kashmir has the highest number of vulnerable glacial lakes followed by Arunachal Pradesh and Sikkim.  

Different studies use different data and methodologies. Hence, their outcomes are not always comparable.  

Way forward 

Threats from GLOFs are likely to increase with time due to global warming. Multi-pronged action is required  

  • Intense monitoring of meteorological events near the snout of vulnerable glacier lakes is an urgent necessity.  
  • Data should be gathered at observatories and communicated to a centralised office.  
  • It should be processed in real-time to forecast the behaviour of glacial lakes and alert people.  
  • Water levels in rivers downstream of vulnerable lakes should also be monitored continuously.  
  • A nationwide programme to regularly monitor vulnerable glacier lakes by satellites and drones should be initiated.  
  • Hydrometeorological information and data gathered through monitoring should be combined to issue forecasts and warnings. 
  • Infrastructure projects in mountains like dams, bridges and highways, must be subjected to stringent quality control measures 
  • Scientific studies on glaciers in the country must be scaled up. Lack of funds and skilled personnel today mean that very few glaciers are monitored.  

The Himalayan region requires a comprehensive risk assessment that accounts for projected temperature rise, changes in precipitation patterns, and land-use/cover changes. This assessment should inform disaster risk-reduction strategies.
