Cyber Security – CERTs, Policy, etc

Cybercrime in India

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Indian evidence act

Mains level: Cybersecurity

cybercrimeContext

  • There has been a steady spike in cases of cybercrime in the last five years.

What is a cybercrime?

  • Cybercrime is any criminal activity that involves a computer, networked device or a network. While most cybercrimes are carried out in order to generate profit for the cybercriminals, some cybercrimes are carried out against computers or devices directly to damage or disable them.

What data states?

  • India reported 52,974 cases of cybercrime in 2021, an increase of over 5 per cent from 2020 (50,035 cases) and over 15 per cent from 2019 (44,735 cases), according to latest government data.

How many cyber criminals are caught in India?

In 2020, over 18.4 thousand people were arrested on account of cyber-crimes across India.

Who is responsible for cyber security centre or state?

  • With ‘police’ and ‘public order’ being in the State List, the primary obligation to check crime and create the necessary cyberinfrastructure lies with States.
  • At the same time, with the IT Act and major laws being central legislations, the central government is no less responsible to evolve uniform statutory procedures for the enforcement agencies.

cybercrimeStatus of cyber investigation

  • There is no separate procedural code for the investigation of cyber or computer-related offences.
  • As electronic evidence is entirely different in nature when compared with evidence of traditional crime, laying down standard and uniform procedures to deal with electronic evidence is essential.

What are general guidelines for cyber investigation?

  • The broad ‘guidelines for the identification, collection, acquisition and preservation of digital evidence’ are given in the Indian Standard IS/ISO/ IEC 27037: 2012, issued by the Bureau of Indian Standards (BIS).
  • This document is fairly comprehensive and easy to comprehend for both the first responder (who could be an authorised and trained police officer of a police station) as well as the specialist (who has specialised knowledge, skills and the abilities to handle a wide range of technical issues).
  • The guidelines, if followed meticulously, may ensure that electronic evidence is neither tampered with nor subject to spoliation during investigation.

cybercrime
What is the meaning of digital evidence or electronic evidence?

  • Digital evidence is information stored or transmitted in binary form that may be relied on in court. It can be found on a computer hard drive, a mobile phone, among other places. Digital evidence is commonly associated with electronic crime, or e-crime, such as child pornography or credit card fraud.

Arjun Khotkar vs Kailash Gorantyal Judgement

  • The Court held that a certificate under Section 65B(4) of the Indian Evidence (IE) Act was a mandatory pre-requisite for the admissibility of (secondary) electronic record if the original record could not be produced.

What is Indian evidence act?

  • The Indian Evidence Act, originally passed in India by the Imperial Legislative Council in 1872, during the British Raj, contains a set of rules and allied issues governing admissibility of evidence in the Indian courts of law.

Judicial activism for cyber security

  • A significant attempt has been made by the higher judiciary in this field also. As resolved in the Conference of the Chief Justices of the High Court in April 2016, a five judge committee was constituted in July 2018 to frame the draft rules which could serve as a model for the reception of digital evidence by courts.
  • The committee, after extensive deliberations with experts, the police and investigation agencies, finalised its report in November 2018, but the suggested Draft Rules for the Reception, Retrieval, Authentication and Preservation of Electronic Records are yet to be given a statutory force.

What needs to be done?

  • Upgrade cyber labs: The cyber forensic laboratories of States must be upgraded with the advent of new technologies.
  • Digital rupee: Offences related to cryptocurrency remain under-reported as the capacity to solve such crimes remains limited. The central government has proposed launching a digital rupee using block-chain technology soon.
  • Empowering states: State enforcement agencies need to be ready for new technologies. The Centre helps in upgrading the State laboratories by providing modernisation funds, though the corpus has gradually shrunk over the years.
  • Need for localisation of data: Most cybercrimes are trans-national in nature with extra-territorial jurisdiction. The collection of evidence from foreign territories is not only a difficult but also a tardy process.

Conclusion

  • Centre and States must not only work in tandem and frame statutory guidelines to facilitate investigation of cybercrime but also need to commit sufficient funds to develop much-awaited and required cyber infrastructure.

Mains question

Q.With the increasing use of computers in society, cybercrime has become a major issue. Analyse the loopholes in cyber security regime of India by giving suggestions to rectify the same.

MGNREGA Scheme

MGNREGA

Note4Students

From UPSC perspective, the following things are important :

Prelims level: particulars of the scheme

Mains level: social security

MGNREGAContext

  • The delay in payment of wages has pushed MGNREGS workers in West Bengal to the brink. There are allegations of corruption against the State government, the Centre’s reluctance in releasing payments, and the plight of the workers caught in this tussle.

What is MGNREGA?

  • The MGNREGA stands for Mahatma Gandhi National Rural Employment Guarantee Act of 2005. This is labour law and social security measure that aims to guarantee the ‘Right to Work’. The act was first proposed in 1991 by P.V. Narasimha Rao.

Significant Features of the scheme

  • Fixed employment: MGNREGA is unique in not only ensuring at least 100 days of employment to the willing unskilled workers, but also in ensuring an enforceable commitment on the implementing machinery i.e., the State Governments, and providing a bargaining power to the labourers.
  • Assured compensation: The failure of provision for employment within 15 days of the receipt of job application from a prospective household will result in the payment of unemployment allowance to the job seekers.
  • Locality is ensured: Employment is to be provided within 5 km of an applicant’s residence, and minimum wages are to be paid.
  • Legal backing: Thus, employment under MGNREGA is a legal entitlement.

MGNREGAWhat are the issues?

  • Non-purposive spending and corruptions: Many works sanctioned under MGNREGA often seem to be non-purposive. Quite often, they are politically motivated hotspots to create rampant corruption by dominant sections of the local population. Even social audits of such projects are locally manipulated.
  • Workers penalized for administrative lapses: The ministry withholds wage payments for workers of states that do not meet administrative requirements within the stipulated time period (for instance, submission of the previous financial year’s audited fund statements, utilization certificates, bank reconciliation certificates etc). There is no logical or legal explanation for this bizarre arrangement. It is beyond any logic as to why workers would be penalized for administrative lapses.
  • Genuine job cards being deleted: Genuine job cards are being randomly deleted as there is a huge administrative pressure to meet 100 per cent DBT implementation targets in MGNREGA. In states like Jharkhand, there are multiple examples where the districts had later requested to resume job cards after civil society interventions into the matter.
  • Too much centralization weakening local governance: A real-time MIS-based implementation and a centralised payment system has further left the representatives of the Panchayati Raj Institutions with literally no role in implementation. It has become a burden as they hardly have any power to resolve issues or make payments.
  • Local priorities being ignored: MGNREGA could be a tool to establish decentralized governance. But, with the administration almost dictating its implementation, it is literally a burden now for the people and especially for the local elected representatives. The Gram Sabhas and gram panchayats’ plans are never honoured. This is a blatant violation of the Act as well.

MGNREGALack of fund has negative implications

  • Delayed payment: Due to this, payments for MGNREGA workers as well as material costs will be delayed, unless States dip into their own funds.
  • Livelihood loss: MGNREGA data shows that 13% of households who demanded work under the scheme were not provided work.
  • Halt of work: Many workers are simply turned away by officials when they demand work, without their demand being registered at all.
  • Fall in demands: This has led to stop the generation of work. There is an artificial squeezing of demand.

What can be done according to rural development committee?

  • Utilization of funds: A large amount of funds allocated for MGNREGA have remained un-utilised. For example, in 2010-11, 27.31% of the funds remained unutilised. The Committee recommends that the Department of Rural Development should analyse reasons for poor utilisation of funds and take steps to improve the same. In addition, it should initiate action against officers found guilty of misappropriating funds under MGNREGA.
  • Context specific projects and convergence: Since states are at various stages of socio-economic development, they have varied requirements for development. Therefore, state governments should be allowed to undertake works that are pertinent to their context. There should be more emphasis on skilled and semi-skilled work under MGNREGA. In addition, the Committee recommends a greater emphasis on convergence with other schemes such as the National Rural Livelihoods Mission, National Rural Health Mission, etc.
  • Regulation of job cards: Offences such as not recording employment related information in job cards and unlawful possession of job cards with elected PRI representatives and MGNREGA functionaries should be made punishable under the Act.
  • Participation of people with disabilities: Special works (projects) must be identified for people with disabilities and special job cards must be issued and personnel must be employed to ensure their participation.
  • Payment of unemployment allowance: Dated receipts for demanded work should be issued so that workers can claim unemployment allowance. Funds for unemployment allowance should be met by the central government.

Some innovation in MGNREGA can address the challenges

1) Looping in the skilled worker

  • First, there is a suggestion to use it to meet the wage cost of their employment in small and medium enterprises (SMEs).
  • Accordingly, skilled migrant workers may be placed in SMEs and their wages would be charged to MGNREGA.

2) Including farm related works

  • In the last few years, un-remunerative prices of several crops have been the root cause of widespread agrarian distress.
  • The suggestion is to allow farmers to employ MGNREGA workers in agricultural operations like land preparation, sowing, transplantation of paddy, plucking of cotton, intercultural operations and harvesting of crops etc. so as to reduce the cost of cultivation.
  • The idea is to pay part of the wages of labour in agricultural operations from MGNREGA.

3) Increasing the number of Work Schemes

  • Currently, there are only 2-3 work schemes (say PMAY) running per panchayat, which is leading to the crowding of workers at worksites.
  • To prevent this and to ensure that all willing households are able to access employment through NREGA, the number of schemes needs to be increased, and 6-8 schemes must be introduced in each village.

4) Paying Workers Immediately

  • Rural households urgently need cash-in-hand, and so the emerging demand is for immediate payment to workers. NREGA payments are frequently delayed by weeks or months.
  • Given the circumstances, such delays will be entirely counterproductive.
  • It is recommended that in remote areas, wage payments should be made in cash, and paid on the same day.

Conclusion

  • Government and NGOs must study the impact of MGNREGA in rural areas so as to ensure that this massive anti-poverty scheme is not getting diluted from its actual path.

Mains question

Q. Large scale social security programmes like MGNREGA are subjected to undergo several stumbling blocks in the times to come due to lack of fund. Analyse these roadblocks and give some innovative measures to tackle these roadblocks.

Millet crop is the best solution for climate smart agriculture

Note4Students

From UPSC perspective, the following things are important :

Prelims level: examples of nutri-cereals

Mains level: climate resilient agriculture

milletContext

  • Government push to coarse cereals as climate change affects wheat, paddy cultivation

What are millets crops?

  • Millets are a group of highly variable small-seeded grasses, widely grown around the world as cereal crops or grains for human food and as fodder.

Features Millet crops in India

  • Big three: The three major millet crops currently growing in India are jowar (sorghum), bajra (pearl millet) and ragi (finger millet).
  • Examples: India also grows a rich array of bio-genetically diverse and indigenous varieties of “small millets” like kodo, kutki, chenna and sanwa.
  • Area of production: Major producers include Rajasthan, Andhra Pradesh, Telangana, Karnataka, Tamil Nadu, Maharashtra, Gujarat and Haryana.

milletWhat are Advantages of millet cultivation?

  • Low input cost: cereals are good for the soil, have shorter cultivation cycles and require less cost-intensive cultivation.
  • Climate resilience: These unique features make millets suited for and resilient to India’s varied agro-climatic conditions.
  • Drought tolerance: cereals are not water or input-intensive, making them a sustainable strategy for addressing climate change and building resilient agri-food systems.

milletReduction in millet production

  • Effects of Green Revolution: The Green Revolution succeeded in making India food sufficient, however, it also led to water-logging, soil erosion, groundwater depletion and the unsustainability of agriculture.
  • Deficit mind-set: Current policies are still based on the “deficit” mind-set of the 1960s.
  • Biased policies: The procurement, subsidies and water policies are biased towards rice and wheat.
  • Skewed cropping pattern: Three crops (rice, wheat and sugarcane) corner 75 to 80 per cent of irrigated water.
  • Lack of diversification: Diversification of cropping patterns towards cereals, pulses, oilseeds, horticulture is needed for more equal distribution of water, sustainable and climate-resilient agriculture.

What can be done to promote millets as nutri-cereals?

1) Rebranding the cereals as nutri-cereals

  • The first strategy from a consumption and trade point of view was to re-brand coarse cereals/millets as nutri-cereals.
  • As of 2018-19, millet production had been extended to over 112 districts across 14 states.

2) Incentive through hiking MSP

  • Second, the government hiked the MSP of nutri-cereals, which came as a big price incentive for farmers.
  • From 2014-15 to 2020 MSPs for ragi has jumped by 113 per cent, by 72 per cent for bajra and by 71 per cent for jowar.
  • MSPs have been calculated so that the farmer is ensured at least a 50 per cent return on their cost of production.

3) Providing steady markets through inclusion in PDS

  • To provide a steady market for the produce, the Modi government included millets in the public distribution system.

4) Increasing area, production and yield

  • The Ministry of Agriculture & Farmers’ Welfare is running a Rs 600-crore scheme to increase the area, production and yield of nutri-cereals.
  • With a goal to match the cultivation of nutri-cereals with local topography and natural resources, the government is encouraging farmers to align their local cropping patterns to India’s diverse 127 agro-climatic zones.
  • Provision of seed kits and inputs to farmers, building value chains through Farmer Producer Organisations and supporting the marketability of nutri-cereals are some of the key interventions that have been put in place.

5) Intersection of agriculture and nutrition

  • The Ministry of Women and Child Development has been working at the intersection of agriculture and nutrition by -1) setting up nutri-gardens, 2) promoting research on the interlinkages between crop diversity and dietary diversity 3) running a behaviour change campaign to generate consumer demand for nutri-cereals.

Conclusion

  • India should aim for a food systems transformation, which can be inclusive and sustainable, ensure growing farm incomes and nutrition security. As the government sets to achieve its agenda of a malnutrition-free India and doubling of farmers’ incomes, the promotion of the production and consumption of nutri-cereals seems to be a policy shift in the right direction.

Mains question

Q. Promotion of millet crops serves the dual purpose of securing health and supporting farmers. Elucidate.

Foreign Policy Watch: Indo-Pacific and QUAD

QUAD

Note4Students

From UPSC perspective, the following things are important :

Prelims level: QUAD

Mains level: Read the attached story

New Delhi will host an official-level meeting of the Quad grouping with the US, Japan and Australia next week, the first such “senior officers meeting” (SOM) to be held since the recent escalation of tensions over the Taiwan Strait.

Quadrilateral Security Dialogue: A Backgrounder

Quadrilateral Security Dialogue or the Quad is an informal strategic forum between the United States, Japan, India and Australia that is maintained by semi-regular summits, information exchanges and military drills between member countries.

  • The US, Japan, India and Australia came together in the aftermath of the 2004 Indian Ocean tsunami to assist the devastated countries.
  • Later, officials of the four countries met in 2007 “to look at issues of common interest.” During an India visit, then Japanese PM Shinzo Abe unveiled the idea of “the Confluence of the Two Seas” that gave birth to the concept of the Indo-Pacific.
  • A decade later officials of the four countries met in the Philippines in 2017 to talk about an aggressively rising China.
  • In 2019, the foreign ministers of the Quad countries met in Washington for the first time.
  • In November, the Quad nations came together to participate in a two-phase joint military exercise, Malabar 2020, in the Bay of Bengal and in the Arabian Sea.

Now it is increasingly viewed as ‘Asian NATO’.

Focus on Indo-Pacific: For the China-wary world

  • The latest meeting of Quad comes at a time when all four countries have either trade or security disputes with China.
  • Despite not explicitly mentioning China, Quad has been openly supporting a “free and fair” Indo-Pacific which is seen as a clear message to Beijing that it needs to curb its assertive behaviour.
  • The optics were hard to miss when India, the US, Japan and Australia joined their navies for the mega Malabar military exercise late last year, an activity which raised alarm in Beijing.
  • This posturing by the Quad nations sent a strong signal to China.

(1) US vs China

  • USA had followed a policy to contain China’s increasing influence in East Asia. Therefore, USA sees the coalition as an opportunity to regain its influence in the Indo-Pacific region.
  • The US has described China, along with Russia, as a strategic rival in its National Security Strategy, National Defence Strategy and the Pentagon’s report on Indo-Pacific Strategy.
  • Both are navigating intense disagreements over trade and human rights in Tibet, Hong Kong and the western Xinjiang region, as well as the coronavirus pandemic and increasing Chinese assertiveness in the South China Sea.

(2) Australia vs China

  • Australia is concerned about China’s growing interest in its land, infrastructure and politics, and influence on its universities.
  • Ties have been on a downward spiral since 2018 when Australia, accusing China of meddling in its domestic affairs, passed a new law against foreign interference and espionage.
  • It also barred Huawei from building the country’s 5G mobile network, among the first countries to do so, citing national security.
  •  The atmosphere worsened when  PM Scott Morrison’s government called for an international inquiry into the origins of the coronavirus that causes Covid-19.

(3) Japan vs. China

  • Tensions between Japan and China over the Senkaku/Diaoyu Islands dispute have recently increased.
  • China has relentlessly continued attempts to unilaterally change the status quo by coercion in the sea area around the Senkaku Islands.
  • The more salient indicator is the number of Chinese patrols inside the territorial sea of the islands, which Japan sees as an explicit violation of its territorial sovereignty.

(4) India vs. Quad

  • India’s strained relations with China needs no explanation. The year long border dispute is the testimony.
  • The Quad summit is taking place in the backdrop of an ongoing military disengagement between India and China following their months-long border standoff in eastern Ladakh.
  • China is increasing its footprint in our neighborhood through its Belt and Road policy and political coercion following the debt trap are some of the increasing concerns other than economic imbalance.

Opportunities unveiled for India

India’s engagement with the Quad goes back to China’s expanding footprint in South Asia and the Indian Ocean Region over the last few years. India can reap some benefits as discussed below:

 (1) Checkmating the Chinese

  • The maritime sphere is wide open to India to undertake coalition building, rule sets, and other forms of strategic exploration than compared to land borders.
  • The maritime space is more important to China than engaging in land grab attempts in the Himalayas. A huge chunk of Chinese trade happens via the Indian oceanic routes that pass through maritime chokepoints.

(2) Channelizing geo-politics

  • There is a growing great power interest in the maritime sphere, especially with the arrival of the concept of ‘Indo-Pacific’. For instance, many European countries have recently released their Indo-Pacific strategies.
  • The most recent was for France to send its warship in the international waters of the South China Sea.

(3) Maritime domain for India

  • Above is the backdrop against which one must see the progressive evolution of Exercise “Malabar”,
  • In the beginning, it was a bilateral event involving just the Indian and US navies. It became tri-lateral with the inclusion of Japan in 2015.
  • And now it has transformed into a four-cornered naval drill that will also include Australia.

(4) Check on China’s India Ocean Ambitions

  • The Quad has a valuable role to play as a check on China’s Indian Ocean ambitions.
  • India must develop ingrained habits of interoperable cooperation with its Quad partners.
  • This interoperable cooperation could pre-emptively dissuade China from mounting a naval challenge in its backyard.

(5) Eccentricity in South Asia

  • With India, located right at the centre of the Indo-Pacific geopolitical imagination can realize the vision of a ‘broader Asia’ that can extend its influence away from geographical boundaries.
  • Further, India with Quad countries can check the imperialist policies of China in the Indian Ocean region and ensure Security and growth for all in the region.

Issues with Quad

(1) Structural problems

  • The Quad has a core structural problem as its objective pivots around the U.S.
  • The Quad riles China as a hostile grouping, but hardly serves the security interests of its members.
  • Despite rhetoric relating to the promotion of a ‘rules-based’ world order, the Quad neither shares a strategic vision nor is it animated by a shared agenda.

 (2) Nature of alliance

  • Alliances involve written commitments to come to the defence of the other against a third party.
  • Despite the potential for cooperation, the Quad remains a mechanism without a defined strategic mission.

(3) Economic alliance not feasible

  • Quad is neither a military alliance nor an economic partnership.
  • Its intention to counter China in the rare-earth sector is logical given the dominant role the country plays in supplying more than half of the world’s such key materials.
  • But, for a country like India, the lack of relevant technologies and talent pool could obstruct its progress in building up a supply chain from scratch.

 (4) Overt emphasis on Maritime domain

  • The entire focus on the Indo-Pacific makes the Quad a maritime, rather than a land-based grouping, raising questions whether the cooperation extends to the Asia-Pacific and Eurasian regions.
  • India’s core concerns with China are primarily undemarcated borders and trade deficit.

 (5) Lack of existence of Indo-Pacific system

  • There has never been Indo-Pacific system ever since the rise of the port-based kingdoms of Indochina in the first half of the second millennium.
  • There were two Asian systems — an Indian Ocean system and an East Asian system — with intricate sub-regional balances.
  • The effort by a U.S. to artificially manufacture to combine the Indo and the Pacific into a unitary system is unlikely to succeed.

(6) Indian borders can go more vulnerable

  • A lesson for India is China’s long-held and strategic interest in parts of Jammu and Kashmir.
  • It is wrongly argued that it is Pakistan that is the issue in J&K.
  • China undoubtedly is as big an issue but has quietly hidden behind Pakistan’s cover.

Challenges: China will retaliate

(1) China’s assertiveness

  • China claims that it has historical ownership over nearly the entire region of South China Sea, which gives it the right to manufacture islands.
  • However, the International Court of Arbitration rejected the claim in 2016.
  • Since then, the incidences of Chinese transgression has only increased making China more assertive for its interest.

(2) Preying small nations

  • The ASEAN countries have a well-knit relationship with China. So are other SAARC countries have fallen prey to Chinese debt traps.
  • The Regional Cooperation Economic Partnership (RCEP) is a recent example of China’s increasing influence over ASEAN nations to which Australia is even a forerunner.

(3) Chinese monopoly

  • Considering the economic might of China and the dependence of Quad nations like Japan and Australia on China, the Quad nations cannot afford to have strained relations with it in the long run.
  • India too, is still very heavily dependent on Chinese exports.

Way Forward

  • Need for a clearer vision: It is important for members of the Quad not to be reactive. It is also important to exhibit openness, and ensure that all talk of a ‘Free and Open Indo-Pacific’ is more than just a mere slogan.
  • Consensus for a common objective: The Quad nations need to better explain the Indo-Pacific Vision in an overarching framework with the objective of advancing everyone’s economic and security interests.
  • Setting an agenda: This will reassure the littoral States that the Quad will be a factor for regional benefit, and a far cry from Chinese allegations that it is some sort of a military alliance. Future meetings can be an opportunity to define the idea and chart a future path.
  • Expanding Quad: India has many other partners in the Indo-Pacific; therefore India should pitch for countries like Indonesia, Singapore to be invited to join in the future. There is also a vital need to economically expand the Quad.

Climate Change Impact on India and World – International Reports, Key Observations, etc.

What causes Rainbow Clouds (Cloud Iridescence)?

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Cloud iridescence

Mains level: NA

Last week, pictures of an unusually-shaped rainbow cloud that appeared over China were widely shared on social media.

What is the news?

  • The cloud in question resembles a pileus cloud.
  • Such phenomenon of bright colours appearing on a cloud is called cloud iridescence.

What is a Pileus Cloud?

  • A pileus cloud is usually formed over a cumulus or cumulonimbus cloud.
  • It is formed when the base cloud pushes a moist current of air upwards and the water vapour from the current condenses to somewhat resemble wave-like crests, or umbrellas.
  • In popular western culture, it is called as an “accessory cloud” that is “rather like a cloud haircut”.
  • A pileus cloud is transient in nature and lasts barely for a few minutes, making it difficult, and at the same time, exciting, to spot.

What is cloud iridescence?

  • Cloud iridescence or Irisation is an optical phenomenon that mostly occurs in wave-like clouds, including pileus and Altocumulus lenticularis.
  • Iridescence in clouds means the appearance of colours on clouds, which can either be in the form of parallel bands like in a rainbow, or mingled in patches.
  • In ancient Greek mythology, Iris is the goddess of rainbow. “Irisation”, the phenomenon of rainbow-like colours in clouds, is derived from her name.

What is a photometeor?

  • Iridescence of clouds is a photometeor.
  • It is an optical phenomenon produced by the reflection, refraction, diffraction or interference of sunlight.

What causes cloud iridescence?

  • In pileus clouds, small water droplets or ice crystals, usually of a similar size, diffract the sunlight falling on them.
  • The thinness of the cloud ensures more exposure to sunlight for each water droplet or ice crystal.
  • To ensure its wave crest-like appearance, water droplets or ice crystals in these clouds are always moving – droplets form at one side of the cloud and evaporate from the other end – and hence these clouds remain small and thin since the droplets have no way of combining and growing in size.
  • In its International Cloud Atlas, the World Meteorological Organisation says that iridescence or Irisation is caused by diffraction within 10 degrees from the sun.
  • Beyond ten degrees and up till about 40 degrees, interference of light is the main cause of iridescence.

Russian Invasion of Ukraine: Global Implications

Nord Stream Pipeline to remain shut

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Nord Stream Pipelines

Mains level: Economic impact of Russian invasion

Russian has said that it can‘t resume the supply of natural gas through a key pipeline to Germany for now because of what it said was a need for urgent maintenance work.

Why in news?

  • There are growing concerns in European countries that Russia would shut down its gas supplies in retaliation against the current sanctions against Moscow.

What is Nord Stream 1?

  • It is a system of offshore natural gas pipelines running under the Baltic Sea from Russia to Germany.
  • Nord Stream 1 is a 1,224 km underwater gas pipeline that runs from Vyborg in northwest Russia to Lubmin in northeastern Germany via the Baltic Sea.
  • Two further pipelines under construction running from Ust-Luga to Lubmin termed Nord Stream 2.
  • Majority owned by the Russian energy giant Gazprom, the pipeline is the primary route through which its gas enters Germany.

Worry for Europe

  • There have been growing concerns that there could be further restrictions to European gas supplies.
  • European countries rely on Russian energy for their cold winters.
  • But now they believe that Russia could weaponized their dependency as a response to their sanction due to the conflict in Ukraine.

What are Europe’s alternative sources of energy?

  • As an alternative source for energy, European countries have increasingly turned towards the US, from whom they purchase liquified natural gas (LNG) that comes via ships.
  • Since ship-delivered gas ends up being far more expensive, there are also attempts to get non-Russian pipeline gas from Norway and Azerbaijan.
  • While EU countries were earlier seeking to phase out fossil fuels and emphasize renewable forms of energy, many are now returning to coal to deal with the energy crisis.
