    Erosion hotspot: Ladakh region

    • The Ladakh Himalaya forms a high altitude desert between Greater Himalayan ranges and Karakoram Ranges.
    • The Indus and its tributaries are major rivers flowing through the terrain.
    • The Zanskar River is one of the largest tributaries of the upper Indus catchment, draining orthogonally through highly deformed Zanskar ranges.

    Zanskar: A major river in Ladakh

    • Two prominent tributaries of Zanskar River are the Doda and Tsrap Lingti Chu, which confluence at Padam village in the upper valley to form the Zanskar River.
    • Zanskar catchment was explored to understand the landform evolution in the transitional climatic zone, using morpho-stratigraphy and study of landforms like valley fill terraces, alluvial fans (triangle-shaped deposit of gravel, sand, and even smaller pieces of sediment, such as silt).

    Zanskar Padam

    • Zanskar river makes a deep gorge in its lower reaches with the headwaters in upper Zanskar makes wide basin called as Padam.
    • The basin stores large amount of sediments in form of fans and river terrace deposits
    • The research suggested that the wide valley of Padam, with an area of 48 square km, in the upper Zanskar, has stored a vast amount of sediments in these landforms.
    • Thus Padam valley is a hotspot of sediment buffering in the Zanskar.

    Sediment study reveals the erosion

    • The study suggested that most sediments were derived from Higher Himalayan crystalline that lies in the headwater region of Zanskar.
    • It was found out that dominant factors responsible for sediment erosion were deglaciation and Indian Summer Monsoon derived precipitation in the headwaters despite the presence of a geomorphic barrier (the deep, narrow gorge).

    Significance of the study

    • The scientists have traced where the rivers draining Himalaya and its foreland erode the most and identify the zones that receive these eroded sediments and fill up.
    • The study will help understand river-borne erosion and sedimentation, which are the main drivers that make large riverine plains, terraces, and deltas that eventually become the cradle to evolving civilizations.
    • It will also help study the dynamics of devastating floods created by these Himalayan rivers in recent times.
    • Thus, the understanding of water and sediment routing becomes crucial while developing infrastructure and for other development works in the river catchment area.
  • Why May 1 is observed as Labour Day?

    Today (May 1) is May Day, also known as International Workers’ Day and as Labour Day in different parts of the world. It is an occasion that commemorates the contributions of workers and the historic labour movement.

    Personality based history question in the UPSC CSE prelims is on the way to become the new normal. Kindly note all such phenomena in the news which tend to invoke some aspects of the modern Indian history. You can find all such news here.

    The Haymarket incident

    • While observed as an ancient northern hemisphere spring festival, May 1 became associated with the labour movement in the late 19th century, after trade unions and socialist groups designated it as a day in support of workers.
    • It was decided to do so in memory of the Haymarket affair of 1886, in Chicago in the United States, in which a peaceful rally in support of workers led to a violent clash with the police, leading to the deaths of 4 civilians and 7 police officers.
    • Many of the agitationists, who were protesting workers’ rights violations, straining work hours, poor working conditions, low wages and child labour, were arrested and served terms of life imprisonment, death sentences, etc., and those who died were hailed as “Haymarket Martyrs”.
    • The incident is believed to have given the workers’ movement a great impetus.

    Linked to the Russian Revolution

    • In 1889, The Second Communist International, an organisation created by socialist and labour parties, declared that May 1 would be commemorated as International Workers’ Day from then on.
    • Finally, in 1916, the US began to recognise eight-hour work timings after years of protests and uprisings.
    • In 1904, the International Socialist Congress at Amsterdam called on to demonstrate energetically on the First of May for the legal establishment of the 8-hour day.
    • After the Russian Revolution in 1917, the celebration was embraced by the Soviet Union and the Eastern bloc nations during the Cold War– becoming a national holiday in many of them.
    • Parades were a part of the celebration– the one at Moscow’s Red Square was attended by top Communists leaders and displayed Soviet military might.

    Indian Case

    • In India, May Day was first celebrated on May 1, 1923, after the Labour Kisan Party of Hindustan initiated and Comrade Singaravelar (Singaravelu Chettiar) helmed the celebrations.
    • Chettiar was known for being one of the leaders of Self Respect Movement in the Madras Presidency and for his fight for the rights of backward classes.
    • In one of his meetings, Chettiar passed a resolution stating the government should allow everybody a national holiday on Labour Day.
  • Festival in news: Chithirai Festival

    For the first time, in place of Madurai’s Chithirai Festival, a simple celestial union is set to take place that will be streamed online.

    Match the pair based question can be asked from festivals as such. Recently, the following festivals were in the news: Ambubachi Mela, Thrisoor Puram, Meru Jatara, Nagoba Jatara etc.

    Chithirai Festival

    • Chithirai Festival or Chithirai Thiruvizha is an annual celebration celebrated in the city of Madurai during the month of April.
    • It is celebrated during the Tamil month of Chithirai.
    • It lasts for one month of which the first 15 days mark the celebrations of the coronation of Goddess Meenakshi and the Marriage of Lord Sundareswara and Goddess Meenakshi.
    • The next 15 days mark the celebrations of the Journey of Lord Alagar from Kallazhagar temple in Alagar Koyil to Madurai.

    About Meenakshi Temple

    • The ancient city of Madurai, more than 2,500 years old, was built by the Pandyan king, Kulashekarar, in the 6th century B.C.
    • But the reign of the Nayaks marks the golden period of Madurai when art, architecture and learning flourished expansively.
    • The most beautiful buildings in the city including its most famous landmark, the Meenakshi temple, were built during the Nayak rule.
    • Located in the heart of the city, the Meenakshi-Sundareshwarar temple is dedicated to goddess Meenakshi, the consort of lord Shiva.
    • The sculpted pillars are adorned with the exquisite murals that celebrate the ethereal beauty of princess Meenakshi and the scenes of her wedding with Lord Shiva.
    • The pillars depict scenes from the wedding of Meenakshi and Sundareswarar. There are 985 richly carved pillars here and each one surpasses the other in beauty.
  • Religious Freedom and India

    The U.S. Commission on International Religious Freedom (USCIRF) has downgraded India to the lowest ranking, “countries of particular concern” (CPC) in its 2020 report.

    Religious freedom in India has been a contested issue since decades. Recent moves by the govt. since the abrogation of Art. 370 which triggered the riots in Delhi has left a big scar on the secular fabric of India.

    About USCIRF

    • It is a U.S. federal government commission created by the International Religious Freedom Act (IRFA) of 1998.
    • Its principal responsibilities are to review the facts and circumstances of violations of religious freedom internationally.

    Accusing India of religious intolerance

    • USCIRF has placed India alongside China, North Korea, Saudi Arabia and Pakistan.
    • India was categorised as a “Tier 2 country” in last year’s listing.
    • This is the first time since 2004 that India has been placed in the CPC category.
    • The commission also recommended that the U.S. government take stringent action against India under the “International Religious Freedom Act” (IRFA).

    What led India to lower its religious freedom?

    • India took a sharp downward turn in 2019 due to concerns about the Citizenship Amendment Act, the proposed National Register for Citizens, anti-conversion laws and the situation in Jammu and Kashmir.
    • The report accuses India using its strengthened parliamentary majority to institute national-level policies violating religious freedom across India.
    • The panel reported harassment and violence against religious minorities to continue with impunity, and engaged in and tolerated hate speech and incitement to violence against them.

    India’s reaction

    • The Centre reacted sharply to the USCIRF report terming it “biased and tendentious” and rejected its observations.
    • The biased and tendentious comments against India are not new. But on this occasion, its misrepresentation has reached new levels.
    • Major panellists of USCIRF dissented with the recommendation on India as being ‘too harsh’ and that ended up placing the country alongside what they termed as “rogue nations” like China and North Korea.
    • India regards the accusations as inaccurate and unwarranted and questioned the body’s “locus standi” in India’s internal affairs.

    US’s religious activism: Unwelcomed by all

    • The US earlier this month has announced the launch of a 27-nation International Religious Freedom Alliance, which aim to adopt a collective approach in protecting and preserving religious freedom across the world.
    • Among the prominent countries to join the alliance are Brazil, the United Kingdom, Israel, Ukraine, the Netherlands and Greece.
    • The USCIRF has been accused worldwide of being biased towards focusing on the persecution of Christians and of being anti-Muslim & Hinduphobic. It panels various controversial personalities.
  • [pib] Petersberg Climate Dialogue

    India along with 30 countries deliberated on issues of Climate Change in first-ever virtual Petersberg Climate Dialogue.

    Climate change negotiations are somehow put to a halt due to ongoing pandemic. Such small dialogues are keeping alive the spirit of climate action.

    Petersberg Climate Dialogue

    • It has been hosted by Germany since 2010 to provide a forum for informal high-level political discussions, focusing both on international climate negotiations and the advancement of climate action.
    • This year’s virtual Dialogue was co-chaired by Germany and the UK.
    • The dialogue was crucial because of the efforts to contain coronavirus as well as countries preparing to move into the implementation phase of the Paris Agreement 2015 in the post-2020 period.

    India’s Contributions

    • Expressing solidarity with the world as it combats the COVID 19 pandemic the Union Minister highlighted how COVID – 19 has noticed that we can survive on less.
    • India pushed for having climate technology as an open source available to all countries at affordable prices.
    • India stressed on climate finance and urged to plan for 1 trillion USD in grants to the developing world immediately.
    • India focussed on the opportunity that the world has today to accelerate renewable energy deployment and creating new green jobs in the renewable energy and energy efficiency sector.
  • New list of names of tropical cyclones over north Indian Ocean

    The India Meteorological Department (IMD) has released a new list containing 169 names of future tropical cyclones that would emerge in the Bay of Bengal and the Arabian Sea.

    When is the name of a Tropical Cyclone declared?

    • Names are declared when TCs are diagnosed with maximum sustained surface wind-speed of 34 knots (62 kmph) or more as per Global Data Processing and Forecasting System (GDPFS) Manual of WMO.
    • Panel Members’ names will be listed alphabetically country-wise.

    We can expect a statement based prelim question like – Which of the following criterion are followed while naming a tropical cyclone?

    Who is involved in the naming of Tropic Cyclone?

    • Worldwide there are six regional specialised meteorological centres (RSMCs) and five regional Tropical Cyclone Warning Centres (TCWCs) mandated for issuing advisories and naming of tropical cyclones.
    • IMD is one of the six RSMCs to provide tropical cyclone and storm surge advisories to 13 member countries under WMO/ESCAP Panel.
    • The panel countries include Bangladesh, India, Iran, Maldives, Myanmar, Oman, Pakistan, Qatar, Saudi Arabia, Sri Lanka, Thailand, United Arab Emirates and Yemen.
    • RSMC, New Delhi is also mandated to name the Tropical Cyclones developing over the North Indian Ocean (NIO) including the Bay of Bengal and the Arabian Sea.

    Since when did naming begin?

    • The WMO/ESCAP Panel on Tropical Cyclones (PTC) at its twenty-seventh Session held in 2000 in Muscat, agreed in principle to assign names to the tropical cyclones in the Bay of Bengal and the Arabian Sea.
    • After long deliberations among the member countries, the naming of the tropical cyclones over the north Indian Ocean commenced from September 2004.
    • This list contained names proposed by the eight member countries of WMO/ESCAP PTC, viz., Bangladesh, India, Maldives, Myanmar, Oman, Pakistan, Sri Lanka and Thailand.

    Why name Cyclones?

    The naming of Tropical Cyclones (TC) helps the scientific community, disaster managers, media and general masses to-

    • identify each individual cyclone.
    • create awareness of its development.
    • remove confusion in case of simultaneous occurrence of TCs over a region
    • remember a TC easily
    • rapidly and effectively disseminate warnings to a much wider audience

    Major criteria adopted for naming

    • The proposed name should be neutral to (a) politics and political figures (b) religious believes, (c) cultures and (d) gender
    • The name should be chosen in such a way that it does not hurt the sentiments of any group of the population over the globe
    • It should not be very rude and cruel in nature
    • The maximum length of the name will be eight letters
    • The Panel reserves the right to reject any name if any of the criteria above are not satisfied
    • The names of tropical cyclones over the north Indian Ocean will not be repeated. Once used, it will cease to be used again.

  • Raja Ravi Varma, the painter who helped Indians bring their gods home

    April 29 is the birth anniversary of the famed Indian painter Raja Ravi Varma (1848-1906), remembered for giving Indians their western, classical representations of Hindu gods and goddesses.

    Raja Ravi Varma

    • Varma was born into aristocracy at Kilimanoor in the erstwhile Travancore state of present-day Kerala and was closely related to its royal family.
    • At the age of 14, Varma was patronised by Ayilyam Thirunal, the then ruler of Travancore, and went on to receive training in watercolours from Ramaswamy Naidu, the royal painter.
    • Later, Varma studied oil painting with the British painter Theodore Jensen.
    • Apart from Travancore, Varma also worked for other wealthy patrons such as the Gaekwad of Baroda.

    Major works

    • A prolific artist, Varma is believed to have made around 7,000 paintings before his death.
    • Varma worked on both portrait and landscape paintings and is considered among the first Indian artists to use oil paints.
    • Apart from painting Hindu mythological figures, Varma also made portraits of many Indians as well as Europeans.
    • His most famous works include Damayanti Talking to a Swan, Shakuntala Looking for Dushyanta, Nair Lady Adorning Her Hair, and Shantanu and Matsyagandha.

    His legacy

    • He continues to be regarded as the most important representative of the Europeanized school of painting in India.
    • His 1873 painting, Nair Lady Adorning Her Hair, won Varma prestigious awards including Governor’s Gold Medal when it was presented in the Madras Presidency and Certificate of Merit at an exhibition in Vienna.
    • In 1904, the British colonial government awarded Varma with the Kaiser-i-Hind Gold Medal.
    • In 2013, a crater on the planet Mercury was named in his honour.
  • How the ozone layer hole over Arctic closed?

    Recently the EU’s Copernicus Atmosphere Monitoring Service (CAMS) announced that a hole in the Arctic ozone layer, believed to be the biggest reported, has closed.

    What healed the hole in the Ozone?

    • The ozone hole’s closing was because of a phenomenon called the polar vortex, and not because of reduced pollution levels due to Covid-19 lockdowns around the world.
    • The hole in the North Pole’s ozone layer, which was first detected in February, had since reached a maximum extension of around 1 million sq km.

    Ozone hole

    • The ‘ozone hole’ is not really a hole — it refers to a region in the stratosphere where the concentration of ozone becomes extremely low in certain months.
    • Ozone, made up of three oxygen atoms, occurs naturally in small amounts.
    • Roughly 10 km to 40 km up in the atmosphere (the layer called the stratosphere), the ozone layer is sunscreen, shielding Earth from harmful ultraviolet radiation.
    • Manufactured chemicals deplete the ozone layer. Each spring over Antarctica (it now springs there), atmospheric ozone is destroyed by chemical processes.
    • This creates the ozone hole, which occurs because of special meteorological and chemical conditions that exist in that region.

    The importance of the ozone layer

    • Ozone (chemically O3, a molecule of three oxygen atoms) is found mainly in the upper atmosphere, an area called the stratosphere, between 10 and 50 km from the earth’s surface.
    • Though it is talked of as a layer, ozone is present in the atmosphere in rather low concentrations.
    • Even at places where this layer is thickest, there are not more than a few molecules of ozone for every million air molecules.
    • They perform a very important function. By absorbing the harmful ultraviolet radiations from the sun, the ozone molecules eliminate a big threat to life forms on earth.
    • UV rays can cause skin cancer and other diseases and deformities in plants and animals.

    Why this year’s hole was massive?

    • This year, the ozone depletion over the Arctic was much larger.
    • Scientists believe that unusual atmospheric conditions, including freezing temperatures in the stratosphere, were responsible.
    • Cold temperatures (below -80°C), sunlight, wind fields and substances such as chlorofluorocarbons (CFCs) were responsible for the degradation of the Arctic ozone layer.
    • Although Arctic temperatures do not usually fall as low as in Antarctica, this year, powerful winds flowing around the North Pole trapped cold air within what is known as the polar vortex.
    • By the end of the polar winter, the first sunlight over the North Pole initiated this unusually strong ozone depletion—causing the hole to form.

    How long it will take for complete recovery?

    • As per the Scientific Assessment of Ozone Depletion data of 2018, the ozone layer in parts of the stratosphere has recovered at a rate of 1-3 per cent per decade since 2000.
    • At these projected rates, the Northern Hemisphere and mid-latitude ozone is predicted to recover by around 2030, followed by the Southern Hemisphere around 2050, and polar regions by 2060.

  • Who was Lord Basaveshwara?

    Prime Minister has offered his homage to the 12th-century social reformer Basaveshwara on his birth anniversary.

    Vaishnavism and Shaivism are the two most profound strands of Bhakti Movement in Indian history. Enlist all the Bhakti Saints and their theistic philosophy and teachings. Try to spot the minute differences between them.

    Lord Basaveshwara

    • Basaveshwara or Basavanna was an Indian 12th-century statesman, philosopher, a poet and Lingayat saint in the Shiva-focussed Bhakti movement and a social reformer in Karnataka.
    • He lived during the reign of the Kalyani Chalukya/Kalachuri dynasty.
    • He was active during the rule of both dynasties but reached his peak of influence during the rule of King Bijjala II in Karnataka, India .

    Founder of Lingayat cult

    • The traditional legends and hagiographic texts state Basava to be the founder of the Lingayats.
    • However, modern scholarship relying on historical evidence such as the Kalachuri inscriptions state that Basava was the poet-philosopher who revived, refined and energized an already existing tradition.

    His Philosophy

    • Basava’s Lingayat theology was a form of qualified nondualism, wherein the individual Atman (soul) is the body of God, and that there is no difference between Shiva and Atman (self, soul).
    • Basava’s views finds places in Vedanta school, in a form closer to the 11th century Vishishtadvaita philosopher Ramanuja.

    Famous works

    • Basavanna spread social awareness through his poetry, popularly known as Vachanaas.
    • Basavanna rejected gender or social discrimination, superstitions and rituals but introduced Ishtalinga necklace, with an image of the Shiva Liṅga to every person regardless of his or her birth.
    • As the chief minister of his kingdom, he introduced new public institutions such as the Anubhava Mantapa (or, the “hall of spiritual experience”) which welcomed men and women from all socio-economic backgrounds.

    Back2Basics: Bhakti Movement

    • The Bhakti movement refers to the theistic devotional trend that emerged in medieval Hinduism.
    • It originated in eighth-century south India and spread northwards.
    • It swept over east and north India from the 15th century onwards, reaching its zenith between the 15th and 17th century CE.
    • It has traditionally been considered as an influential social reformation in Hinduism, and provided an individual-focused alternative path to spirituality regardless of one’s birth or gender
    • Salvation which was previously considered attainable only by men of Brahmin, Kshatriya and Vaishya castes, became available to everyone.
  • Qissa Khwani Bazaar massacre and the Khudai Khidmatgars

    • Qissa Khwani Bazaar is a renowned market place in the city of Peshawar.
    • Before the Partition, the marketplace was also the site of a massacre perpetrated by British soldiers against non-violent protesters of the Khudai Khidmatgar movement on April 23, 1930.

    We can expect a possible mains question inspired from this newscard. The question could be like- “Discuss the role of Abdul Ghaffar Khan and his Khudai Khidmatgar in infusing the Gandhian principle of non-violence in the Frontiers of India “.

    The Red Shirts:  Khudai Khidmatgars

    • The Khudai Khidmatgar was a non-violent movement against the British occupation of the Indian subcontinent led by Abdul Ghaffar Khan, a Pashtuns freedom fighter, in the North-West Frontier Province.
    • Over time, the movement acquired a more political colour, leading to the British taking notice of its growing prominence in the region.
    • Following the arrest of Khan and other leaders in 1929, the movement formally joined the Indian National Congress after they failed to receive support from the All-India Muslim League.
    • Members of the Khudai Khidmatgar were organised and the men stood out because of the bright red shirts they wore as uniforms, while the women wore black garments.

    Why did the massacre happen?

    • Abdul Ghaffar Khan and other leaders of the Khudai Khidmatgar were arrested on April 23, 1930 by British police after he gave a speech at a gathering in the town of Utmanzai in the North-West Frontier Province.
    • A respected leader well-known for his non-violent ways, Khan’s arrest spurred protests in neighbouring towns, including Peshawar.
    • Protests spilled into the Qissa Khwani Bazaar in Peshawar on the day of Khan’s arrest. British soldiers entered the market area to disperse crowds that had refused to leave.
    • In response, British army vehicles drove into the crowds, killing several protesters and bystanders. British soldiers then opened fire on unarmed protestors, killing even more people.
    • Historical records suggest the British attempted to deploy the Garhwal Regiment against the civilians in the marketplace, but two platoons of this respected regiment refused to shoot at unarmed protesters.
    • In retaliation, British officials court-martialled the platoon members with upto eight years of imprisonment.

    Aftermath of the massacre

    • The British ramped up the crackdown on Khudai Khidmatgar leaders and members following the Qissa Khwani Bazaar massacre.
    • In response, the movement began involving young women in its struggle against the British, a decision in line with tactics adopted by revolutionaries across undivided India.
    • Women were able to move undetected with more ease than men.
    • According to accounts by Khudai Khidmatgar activists, the British subjected members of the movement to harassment, abuse and coercive tactics adopted elsewhere in the subcontinent.
    • This included physical violence and religious persecution. Following the recruitment of women in the movement, the British also engaged in violence, brutality and abuse of women members.

    Khudai Khidmatgars  gets wasted into history

    • British adopted their tactic of sowing divisions on religious grounds in the North-West Frontier Province as well, in an attempt to weaken the Khudai Khidmatgar.
    • In a move that surprised the British government, in August 1931, the Khudai Khidmatgar aligned themselves with the Congress party, forcing the British to reduce the violence they were perpetrated on the movement.
    • The Khudai Khidtmatgar opposed Partition, a stance that many interpreted as the movement not being in favour of the creation of the independent nation of Pakistan.
    • Post 1947, the Khudai Khidmatgar slowly found their political influence decreasing to such an extent that the movement and the massacre 90 years ago in the Bazaar has been wiped out from collective memory (of Pakistan).
