  • [pib] Pasumpon Muthuramalinga Thevar

    The Prime Minister has recalled the rich contributions of Pasumpon Muthuramalinga Thevar on Thevar Jayanthi.

    Who was M. Thevar (1908-1963)?

    • Muthuramalingam was a politician and a patriarch of Thevar community in the state of Tamil Nadu.
    • He was elected three times to the national Parliamentary Constituency.

    His legacy:

    (a) Association with INC

    • Thevar attended the 52nd annual session of the Indian National Congress, held in Tripuri in March 1939.
    • At this meeting the presidency of Subhas Chandra Bose was challenged by Pattabhi Sitaramayya. Sitaramayya had the active support of Gandhi.
    • Bose was elected president again over Gandhi’s preferred candidate Pattabhi Sitaramayya.
    • Thevar strongly supported Bose in the intra-Congress dispute and joined the Forward Bloc.

    (b) Opposition to the Criminal Tribes Act (CTA)

    • The CTA had been enacted in 1920 by the government of the Madras Presidency and was subsequently implemented in a piecemeal fashion.
    • CTA criminalized entire communities by designating them as habitual criminals.
    • Adult males of the groups were forced to report weekly to local police, and had restrictions on their movement imposed.
    • Thevar mobilised resistance to it, touring villages in the affected areas and leading protest rallies for the rights of the individuals registered under it.

    (c) Temple entry movement

    • The Temple Entry Authorisation and Indemnity Act was passed by the government of C. Rajagopalachari in 1939.
    • This removed restrictions prohibiting Dalits from entering Hindu temples.
    • Thevar supported this reform and on 8 July 1939 he helped the activist A. Vaidyanatha Iyer take Dalits to Meenakshi Temple in Madurai.

  • What is Climate Vulnerability Index?

    Environmental think tank Council on Energy, Environment and Water has carried a first-of-its-kind district-level climate vulnerability assessment, or Climate Vulnerability Index (CVI).

    Climate Vulnerability Index

    • The Index takes into account certain indicators when assessing the preparedness of a state or district.
    • It considers:
    1. Exposure (that is whether the district is prone to extreme weather events)
    2. Sensitivity (the likelihood of an impact on the district by the weather event)
    3. Adaptive capacity (what the response or coping mechanism of the district is)

    Significance of CVI

    • CVI helps map critical vulnerabilities and plan strategies to enhance resilience and adapt by climate-proofing communities, economies and infrastructure.
    • Instead of looking at climate extremes in isolation, the study looks at the combined risk of hydro-met disasters, which is floods, cyclones and droughts, and their impact.
    • The study does not take into consideration other natural disasters such as earthquakes.

    Why does India need a climate vulnerability index?

    • According to Germanwatch’s 2020 findings, India is the seventh-most vulnerable country with respect to climate extremes.
    • Extreme weather events have been increasing in the country such as supercyclone Amphan in the Bay of Bengal, which is now the strongest cyclone to be recorded in the country.
    • Recent events such as the landslides and floods in Uttarakhand and Kerala, have also increased in the past decade.
    • Further, the IPCC states that every degree rise in temperature will lead to a three per cent increase in precipitation, causing increased intensification of cyclones and floods.

    Key findings of the CVI

    According to CVI, Assam, Andhra Pradesh, Maharashtra, Karnataka and Bihar are most vulnerable to extreme climate events such as floods, droughts and cyclones in India.

    • 183 hotspot districts are highly vulnerable to more than one extreme climate events
    • 60% of Indian districts have medium to low adaptive capacity in handing extreme weather events – these districts don’t have robust plans in place to mitigate impact
    • North-eastern states are more vulnerable to floods
    • South and central are most vulnerable to extreme droughts
    • 59 and 41 per cent of the total districts in the eastern and western states, respectively, are highly vulnerable to extreme cyclones.

    Best performing states

    • Kerala and West Bengal have performed well comparatively, despite both being coastal states and dealing with the threat of cyclones and floods annually.
    • The reason why these states have performed better is that they have stepped up their climate action plans as well as preparedness to handle an extreme weather event.

    Key recommendations

    • Develop a high-resolution Climate Risk Atlas (CRA) to map critical vulnerabilities
    • Establish a centralised climate-risk commission to coordinate the environmental de-risking mission.
    • Undertake climate-sensitivity-led landscape restoration focused on rehabilitating, restoring, and reintegrating natural ecosystems as part of the developmental process.
    • Integrate climate risk profiling with infrastructure planning to increase adaptive capacity.
    • Provide for climate risk-interlinked adaptation financing by creating innovative CVI-based financing instruments that integrate climate risks for an effective risk transfer mechanism.

  • Sundarbans among 5 sites with highest ‘Blue Carbon’ globally

    India’s Sundarbans National Park is among five sites that have the highest blue carbon stocks globally, according to a new assessment.

    Highlights of the study

    • ‘World Heritage forests’ are now releasing more carbon than they are absorbing, primarily due to human activity and climate change, according to the assessment.
    • UNESCO lists 50 sites across the globe for their unique marine values. These represent just one per cent of the global ocean area.
    • But they comprise at least 15 per cent of global blue carbon assests.

    Try this question from CSP 2021:

    Q. What is blue carbon?

    (a) Carbon captured by oceans and coastal ecosystems

    (b) Carbon sequestered in forest biomass and agricultural soils

    (c) Carbon contained in petroleum and natural gas

    (d) Carbon present in atmosphere

  • Unified Database of Birth and Death

    The Centre has proposed amendments to a 1969 law that will enable it to “maintain the database of registered birth and deaths at the national level”.

    Registration of Births and Deaths Act (RBD), 1969

    • The registration of births, deaths and stillbirths are compulsory under the provisions of RBD Act in all parts of the Country.
    • The normal period of 21 days (from the date of occurrence) has been prescribed for reporting the birth, death and stillbirth events.

    Why need amendment?

    • The database may be used to update the Population Register and the electoral register, and Aadhaar, ration card, passport and driving licence databases after the amendment.
    • Presently, the registration of births and deaths is done by the local registrar appointed by States.

    What are the proposed amendments?

    Ans. Unified Database of Birth and Death

    • It is proposed that the Chief Registrar (appointed by the States) would maintain a unified database at the State level.
    • It would then integrate it with the data at the “national level,” maintained by the Registrar General of India (RGI).
    • The amendments will imply that the Centre will be a parallel repository of data.

    Significance of the database

    • It would help update:
    1. Population Register prepared under the Citizenship Act, 1955;
    2. Electoral registers or electoral rolls prepared under the Representation of the People Act, 1951
    3. Aadhaar database prepared under the Aadhaar Act, 2016;
    4. Ration card database prepared under the National Food Security Act, 2013;
    5. Passport database prepared under the Passport Act; and
    6. Driving licence database under the Motor Vehicles (Amendment) Act, 2019, and
    7. Other databases at the national level are subject to provisons of Section 17 (1) of the RBD Act, 1969

  • Meghalaya to give land rights to men

    Matrilineal Meghalaya is set to break the tradition of share of parental property to the khatduh, which means the youngest daughter in the Khasi language.

    Matrilineal Society of Meghalaya

    • The matrilineal tradition which the Khasi and other subgroups practice in Meghalaya is unique within India.
    • Khasi are an ancient tribe said to be the largest surviving matrilineal culture in the world.
    • Matrilineal principles among the Khasi are emphasised in myths, legends, and origin narratives.

    Their evolution

    • Khasi kings embarking on wars left the responsibility of running the family to women and thus their role in society became very deep rooted and respected.
    • Reference to Nari Rajya (female kingdom; or land of matriarchy) in the epic Mahabharata likely correlates with the Khasi and Jaintia Hills and Meghalaya’s present-day matrilineal culture.

    Property rights

    • The youngest daughter of the family, the Ka Khadduh, inherits all ancestral property.
    • After marriage, husbands live in the mother-in-law’s home.
    • The mother’s surname is taken by children.
    • When no daughters are born to a couple, they adopt a daughter and pass their rights to property to her.
    • The birth of a girl is celebrated while the birth of a son is simply accepted.
    • There is no social stigma attributed to a woman remarrying or giving birth out of wedlock as the “Khasi Social Custom Lineage Act” gives security to them.
    • Care of children is the responsibility of mothers or mothers-in-law.

    Matrilineal, not matriarchal

    • While society is matrilineal, it is not matriarchal. In past monarchies of the state, the son of the youngest sister of the king inherited the throne.
    • Even now in the Meghalaya Legislative Assembly or village councils or panchayats the representation of women in politics is minimal.

    Issues with the system

    • Some Khasi men perceive themselves to be accorded a secondary status.
    • They have established societies to protect equal rights for men.
    • They express that Khasi men don’t have any security, they don’t own land, they don’t run the family business and, at the same time, they are almost good for nothing.

  • Historical Significance of Kushinagar

    The Prime Minister has inaugurated the Kushinagar International Airport in Uttar Pradesh, which will help connect key Buddhist pilgrimage sites.

    About Kushinagar

    • Kushinagar is a town in the Kushinagar district of the Indian state of Uttar Pradesh.
    • It is an important Buddhist pilgrimage site, where Buddhists believe Gautam Buddha attained Mahaparinirvana after his death.
    • It is an international Buddhist pilgrimage centre.
    • It is also at the centre of a Buddhist tourist circuit, which includes Lumbini (Nepal), Sarnath and Bodhgaya.
    • Other Buddhist destinations nearby include Nalanda, Sravasti and Kapilavastu.

    History of Kushinagar

    The present Kushinagar is identified with Kusavati (in the pre-Buddha period) and Kushinara (in the post-Buddha period).

    [A] Ancient

    • Kushinara was the capital of Mallas which was one of the sixteen mahajanpada of the 6th century BCE.
    • Since then, it remained an integral part of the erstwhile empires of Maurya, Shunga, Kushana, Gupta, Harsha, and Pala dynasties.

    [B] Medieval

    • In the medieval period, Kushinagar had passed under the suzerainty of Kultury Kings.
    • Kushinara continued to be a living city till the 12th century CE and was thereafter lost into oblivion.
    • It was believed to be ruled over by a Rajput adventurer, Madan Singh, in the 15th century CE.

    [C] Modern

    • Kushinagar came into prominence in the 19th century with archaeological excavations carried out by Alexander Cunningham, the first Archaeological Surveyor of India.
    • It was later followed by C.L. Carlleyle who exposed the main stupa and also discovered a 10 meters long statue of reclining Buddha in 1876.
    • Excavations continued till 1907 under J. Ph. Vogel, uncovering a wealth of Buddhist materials.
    • Chandra Swami, a Burmese monk, came to India in 1903 and made Mahaparinirvana Temple into a living shrine.

    What is the Buddhist Tourist Circuit?

    • In 2016, the Ministry of Tourism announced the Buddhist Circuit as the country’s first transnational tourism circuit, covering sites in Nepal and Sri Lanka alongside those in India.
    • The map of the Buddhist Circuit includes Bodh Gaya, Vaishali, and Rajgir in Bihar, Kushinagar, Sarnath, and Shravasti in UP, and Lumbini in Nepal.

    Significance of these places

    • The Buddha was born as the prince Siddhartha Gautama in c. 563 BC in Lumbini, and he lived until the age of 29 with his parents in the Shakya capital of Kapilavastu.
    • He attained enlightenment under the Bodhi Tree in Bodh Gaya, and gave his first sermon at Sarnath near Varanasi.
    • He taught in the area around Rajgir, where he was built a forest monastery by king Bimbisara of Magadha, and he lived the largest part of his life as the Buddha in Shravasti.
    • He delivered his last sermon in Vaishali and got parinirvana at Kushinagar.

    Significance of this Circuit

    Ans. Cultural Diplomacy

    • Look East: There is an awareness in the government that the absence of tourist infrastructure is a major reason why India loses out to Southeast Asian nations such as Indonesia and Thailand.
    • Employment through Tourism: The hope is that world-class facilities will be able to attract Buddhist tourists to India, and boost revenues and employment generation.
    • Gaining soft power: The push is intended to assert and consolidate India’s position as the original centre of Buddhism, against the claims from China.

    Questions based on either Buddhism or Jainism,  are all-time favourite of UPSC and are equally invincible.

  • Places in news: Mount Manipur

    The Union government has rechristened Mount Harriet, a historical tourist spot in the Andaman and Nicobar Islands, as ‘Mount Manipur’ to commemorate the1891 Anglo-Manipur war.

    Manipur’s connection to Mount Harriet

    • After the Anglo-Manipur War of 1891, several Manipuris who had fought the British in the war, including Maharaja Kulachandra Dhwaja Singh, were exiled to the British penal colony in the Andaman Islands.
    • Since the cellular jail (Kalapani) was yet to be built, Kulachandra and the prisoners were kept on Mount Harriet, a hillock in what is now the Ferragunj tehsil of South Andaman district.
    • 23 men, including King Kulachandra and his brothers, were “transported for life” to the Andamans.
    • While some died there, Kulachandra was released and shifted elsewhere before his death.

    This is why Mount Harriet is an important symbol of the Anglo-Manipur War of 1891.

    About Anglo-Manipur War of 1891

    • Considered an epoch in the history of Manipur, the Anglo-Manipur War was fought between the kingdom of Manipur and the British over a month in 1891.
    • The battle was triggered by a coup in the palace of Manipur, which had been marked by internal factionalism in the years leading up 1891.
    • The British government took advantage of the internal dissension among the princes of the royal family.

    Battle for throne

    • In 1886, when Surchandra inherited the throne from his father Chandrakirti Singh, the kingdom of Manipur was not under the British rule but had links with the crown through different treaties.
    • However, Surchandra ascension to the throne was controversial and his younger brothers — Kulachadra, Tikendrajit — revolted against him.
    • The1890 coup by the rebel faction deposed Surchandra, and proclaimed Kulachandra, the next oldest brother, the king.
    • Surchandra fled to Calcutta seeking British help to reinstate him.
    • Instead, the British dispatched James Quinton, the Chief Commissioner of Assam, with an army to Manipur.
    • His mission was to recognise Kulachandra as the king under the condition that they be allowed to arrest the coup leader Crown Prince Tikendrajit and deport him from Manipur.

    This aggressive imposition of British law in a sovereign state was rejected by the king, precipitating the Anglo-Manipuri War of 1891.

    Its aftermath

    • In the first phase of the war, the British surrendered and their officers — including Quinton — were executed in public.
    • In the second phase, the British attacked Manipur from three sides, and finally capture the Kangla Fort in Imphal.
    • Prince Tikendrajit and four others were hanged by the British, while Kulachandra, along with 22 others, were banished to the Andaman Islands.

    Significance of the war

    • Many say the war was described as a blow to British prestige.
    • In India, it was viewed as being part of the general uprising against British rule in the country, soon after after the Revolt of 1857.
    • The war led to Manipur officially becoming a princely state under the indirect rule of the British crown.

  • COP26 Climate Conference and Why it is important

    The UK will host the COP 26 UN Climate Change Conference from October 31 to November 12.

    Conference of Parties (CoP): A Backgrounder

    • The CoP comes under the United Nations Climate Change Framework Convention (UNFCCC) which was formed in 1994.
    • The UNFCCC was established to work towards “stabilisation of greenhouse gas concentrations in the atmosphere.”
    • It laid out a list of responsibilities for the member states which included:
    1. Formulating measures to mitigate climate change
    2. Cooperating in preparing for adaptation to the impact of climate change
    3. Promoting education, training and public awareness related to climate change
    • The UNFCCC has 198 parties including India, China and the USA. COP members have been meeting every year since 1995.

    COP1 to COP25: Key takeaways

    COP1: The first conference was held in 1995 in Berlin.

    COP3: It was held in Kyoto, Japan, in 1997, the famous Kyoto Protocol (w.e.f. 2005) was adopted. It commits the member states to pursue limitation or reduction of greenhouse gas emissions.

    COP8: India hosted the eighth COP in 2002 in New Delhi. It laid out several measures including, ‘strengthening of technology transfer… in all relevant sectors, including energy, transport and R&D,  and the strengthening of institutions for sustainable development.

    COP21: it is one of the most important that took place in 2015, in Paris, France. Here countries agreed to work together to ‘limit global warming to well below 2, preferably at 1.5 degrees Celsius, compared to pre-industrial levels.’

    Significance of COP26

    • The event will see leaders from more than 190 countries, thousands of negotiators, researchers and citizens coming together to strengthen a global response to the threat of climate change.
    • It is a pivotal movement for the world to come together and accelerate the climate action plan after the COVID pandemic.

    COP26 goals

    According to the UNFCCC, COP26 will work towards four goals:

    1. Secure global net-zero by mid-century and keep 1.5 degrees within reach
    • The UNFCCC recommends that countries ‘accelerate the phase-out of coal, curtail deforestation, speed up the switch to electric vehicles and encourage investment in renewables’ to meet this goal.
    1. Adapt to protect communities and natural habitats
    • Countries will work together to ‘protect and restore ecosystems and build defences, warning systems and resilient infrastructure and agriculture to avoid loss of homes, livelihoods and even lives.’
    1. Mobilise finance
    • To deliver on first two goals, developed countries must make good on their promise to mobilise at least $100bn in climate finance per year by 2020.
    1. Work together to deliver
    • Another important task at the COP26 is to ‘finalise the Paris Rulebook’. Leaders will work together to frame a list of detailed rules that will help fulfil the Paris Agreement.

    What India could do to reach its targets?

    • Update NDCs: It is time for India to update its Nationally Determined Contributions or NDCs. (NDCs detail the various efforts taken by each country to reduce the national emissions)
    • Effective planning: Sector by sector plans are needed to bring about development. We need to decarbonise the electricity, transport sector and start looking at carbon per passenger mile.
    • Energy transition: Aggressively figure out how to transition our coal sector
    • Robust legal framework: India also needs to ramp up the legal and institutional framework of climate change.

    Try answering this PYQ:

    With reference to the Agreement at the UNFCCC Meeting in Paris in 2015, which of the following statements is/are correct?

    1. The Agreement was signed by all the member countries of the UN and it will go into effect in 2017.

  • Genetic proof for domestication of sheep in Indian subcontinent

    Researchers at the Central University of Kerala (CUK) have found that domestication of sheep had taken place in the Indian subcontinent, especially in the Indus Valley Civilisation (IVC) regions in the 6th or 7th millennium BC.

    Animal domestication in IVC

    A number of domesticated animal species have been found in excavations at the Harappan cities.

    • The Indian humped cattle (Bos indicus) were most frequently encountered, though whether along with a humpless variety, such as that shown on the seals, is not clearly established.
    • The buffalo (B. bubalis) is less common and may have been wild.
    • Sheep and goats occur, as does the Indian pig (Sus cristatus).
    • The camel is present, as well as the ass (Equus asinus).
    • Bones of domestic fowl are not uncommon; these fowl were domesticated from the indigenous jungle fowl.
    • Finally, the cat and the dog were both evidently domesticated.
    • Present, but not necessarily as a domesticated species, is the elephant.
    • The horse is possibly present but extremely rare and apparently only present in the last stages of the Harappan Period.

    Key findings of the study

    • The study has found genetic evidence that sheep had been domesticated in the region in contrast to the general belief that they were domesticated then in West Asia alone.
    • India ranks second in terms of sheep population, represented by as many as 44 well-described breeds in addition to several nondescript species.
    • It highlights that genetic diversity and phylogeography of Indian sheep breeds remained poorly understood, particularly the south Indian breed.

    How was the classification held?

    • Researchers retrieved the mitochondrial DNA sequences of another 11 breeds for analysis, which further strengthened their study.
    • The researchers analysed these sequences along with published data of domestic and wild sheep from different countries, including India.
    • The haplotype diversity observed was relatively high in Indian sheep, which were classified into the three known major mitochondrial DNA lineages namely A, B, and C.

    Diversity among Indian Sheeps

    • It was found that lineage A was predominant among Indian sheep, whereas lineages B and C were observed at low frequencies.
    • Particularly lineage C was restricted to the breeds of northern and eastern India.
    • The study examined the south Indian breeds, provided strong genetic evidence that the Indian subcontinent was one of the domestication centres of the lineage A sheep.
    • When DNA sequences were compared with other breeds across the world, it was found that the Indian sheep haplotypes were unique and highly diverse.
    • The high genetic diversity and statistical analysis suggest that sheep was domesticated in the country.
    • The wild Sheep, O. vignei blanfordi in Mehrgarh [Pakistan], may be a potential progenitor of domestic sheep lineage.

    Breeds studied

    • Among the south Indian breeds, except for Mandya, all others, notably Bellary, Coimbatore, Hassan, Katchaikatty Black, Nilgri, Ramnad White, and Vembur, were fully encompassed with lineage A.
    • However, Kenguri Kilakarsal, Madras Red, Mecheri, and Tiruchy Black breeds, had very low occurrences of lineage B mitochondria.
    • In contrast, a majority of individuals of Mandya and Sonadi breeds carried a relatively high frequency of lineage B.
    • In terms of the conservation of sheep genetic resources, these two breeds are important with respect to maternal lineages.
