  • [pib] Ravines of Chambal-Gwalior Region

    Union Minister of Agriculture & Farmers’ Welfare held a meeting with World Bank representatives to bring large Ravines of Gwalior–Chambal region under agriculture.

    Try this question for mains:

    Q.What is Badland Topography? Discuss the scope of their utilization as arable land in India.

    What are Ravines?

    • Badland topography is a major feature of the Chambal valley is characterized by an undulating floodplain, gullies and ravines.
    • Ravines are a type of fluvial erosional feature and are formed as a result of constant vertical erosion by streams and rivers flowing over semi-arid and arid regions.

    How are they formed?

    • Researchers consider the regional climate as a major factor in the formation of ravines.
    • Climate indeed plays a huge role by supplying the water in the form of rain or snow as well as providing the temperature variations.
    • However, the ravines of Chambal are a bit difficult to be explained solely on climatic terms.
    • The region through which the Chambal River flows does not receive enough rainfall to create ravines that are 60–80 m deep.
    • Researchers have attributed neotectonic activities to the Chambal ravines genesis.

    Other factors

    • It is well known that rivers are full of energy and actively erode in their initial phases and progressively become passive as they attain their base levels.
    • But sometimes, due to tectonic movements, the base level may be lowered further thus energizing the river and reactivating the erosion. This is known as River Rejuvenation.
    • Moreover, wind erosion has also contributed to the formation of Chambal ravines.

    Back2Basics: What are Badlands?

    • Badlands are erosional landforms of highly dissected morphology that are created on soft bedrock in a variety of climate conditions.
    • They develop in arid to semiarid areas where the bedrock is poorly cemented and rainfall is generally heavy and intermittent.
    • The dry, granular surface material and light vegetation are swept from the slopes during showers, leaving the gullies bare.

  • False urban rural binary

    The article brings out the issues in the rural-urban binary, which leads to the disparity in the allocation of resources to the urban areas.

    Congestion and health issues in cities

    • The congestion in large cities has turned out to be their worst enemy during this pandemic.
    • Congestion is most evident in slums in large cities and poses a grave health and environmental challenges.
    • Yet, the Centre’s allocation for the rural component of the Swachh Bharat Mission is about seven times more than for urban areas.
    • Class I cities have 1.4 beds per 1,000 people. (with the population more than 1 lakh)
    • However, the urban support under the National Health Mission is just three per cent of the total allocation, while 97 per cent of the funds are set aside for rural areas.

    Issues with the present urban development programs

    • The Jawaharlal Nehru National Urban Renewal Mission (2005-2014) allocated the bulk of funds to large cities: 70 per cent to large cities and 30 per cent to smaller towns.
    • Atal Mission for Rejuvenation and Urban Transformation (AMRUT) and the Smart Cities Mission, focus on Class I cities.
    • Both these schemes provide funds for the more developed cities that already have relatively better infrastructure.
    • But these schemes overlook the nearly seven crore people who live in smaller towns.
    • These are towns that lag behind in services and infrastructure as compared to the big cities.

    Consider the question “The rural-urban binary has led to the policy formulation in which there is a huge disparity in the allocation of resources and attention on the urban area. Comment.”

    Conclusion

    The pandemic has forced us to reflect on the unequal and unplanned development of urban settlements and the absence of infrastructure to provide for the teeming millions.  The challenges of urban poverty and congestion cry for more attention, more government support.

    (a) 1, 2 and 3

    (b) 2, 3 and 4

    (c) 1, 2 and 4

    (d) 1, 3 and 4

    Siddi Tribe

    • The Siddi also known as Sidi, Siddhi, Sheedi or Habshi, are an ethnic group inhabiting India and Pakistan.
    • They are sometimes referred to as Afro-Indians. They are descended from the Bantu peoples of the East African region.
    • Similarly, another term for Siddis, habshi, is held to be derived from the common name for the captains of the Abyssinian ships that also first delivered Siddi slaves to the subcontinent.
    • They are primarily Muslims, although some are Hindus and others belong to the Catholic Church.

    How they came to India?

    • The first Siddis are thought to have arrived in India in 628 AD at the Bharuch port. Several others followed with the first Arab conquest of the subcontinent in 712 AD.
    • The latter groups are believed to have been soldiers with Muhammad bin Qasim’s Arab army and were called Zanjis.
    • In the Delhi Sultanate period prior to the rise of the Mughals in India, Jamal-ud-Din Yaqut was a prominent Siddi slave-turned-nobleman who was a close confidant of Razia Sultana.
    • Siddis were also brought as slaves by the Deccan Sultanates. They also served in the Navy of Shivaji Maharaj.
    • Several former slaves rose to high ranks in the military and administration, the most prominent of which was Malik Ambar.
    • Later the Siddi population was added to via Bantu peoples from Southeast Africa that had been brought to the Indian subcontinent as slaves by the Portuguese.

  • In news: Madhubani/Mithila Paintings

    An artist known as the ‘mask man’ of Bihar dispatches masks with hand-painted Madhubani motifs all over India.

    [Prelims Spotlight] Indian Paintings and Handicrafts

    Madhubani Paintings

    • Madhubani art (or Mithila painting) is a style of Indian painting, practised in the Mithila region of Bihar.
    • This painting is done with a variety of tools, including fingers, twigs, brushes, nib-pens, and matchsticks and using natural dyes and pigments.
    • It is characterized by its eye-catching geometrical patterns.
    • It was traditionally created by the women of various communities in the Mithila region of the Indian subcontinent.
    • This painting as a form of wall art was practised widely throughout the region; the more recent development of painting on paper and canvas mainly originated among the villages around Madhubani.
    • It is these latter developments that led to the term “Madhubani art” being used alongside “Mithila Painting.”

    Its features

    • It uses two-dimensional imagery, and the colours used are derived from plants. Ochre, Lampblack and Red are used for reddish-brown and black, respectively.
    • It mostly depicts people and their association with nature and scenes and deities from the ancient epics.
    • Natural objects like the sun, the moon, and religious plants like tulsi are also widely painted, along with scenes from the royal court and social events like weddings.
    • Generally, no space is left empty; the gaps are filled by paintings of flowers, animals, birds, and even geometric designs.
    • Madhubani art has five distinctive styles: Bharni, Kachni, Tantrik, Godna and Kohbar.
    • This painting has also received a GI (Geographical Indication) status.

  • How the US’ Trinity Test led to the dawn of the atomic age?

    On this day, exactly 75 years ago, US scientists tested ‘Gadget’— the world’s first atomic bomb — in what was dubbed as the ‘Trinity Test’.

    Practice question for mains:

    Q.What is the Manhattan Project? Describe its consequences on the post-world war scenario.

    The Trinity Test

    • The super bomb, nicknamed ‘Gadget’, was built by a team of scientists at a top-secret site in Los Alamos, New Mexico.
    • It was developed as part of the US-led Manhattan Project, which sought to build nuclear weapons to give the allied forces an edge over Germany, Japan and Italy in World War 2.
    • Very soon after the Trinity test, an identical nuclear bomb called ‘Fat Man’ was dropped on the Japanese city of Nagasaki, killing tens of thousands of people.
    • Before it detonated, the scientists had placed bets on what could happen. Some believed that the bomb would be a dud and would fail to explode.

    What was the Manhattan Project?

    • Germany initiated World War II by invading Poland.
    • A letter signed by Nobel prize-winning physicist Albert Einstein warned then-US President Franklin D Roosevelt of the potential threat posed by an atomic weapon being developed by Adolf Hitler.
    • Soon after, the US launched a secret atomic research undertaking, code-named the Manhattan Project, which sought to develop an atomic weapon to end the war.

    Execution of the project

    • The Project remained a relatively small-scale initiative for the next two years.
    • It was only after the bombing of Pearl Harbour the project was officially kicked into gear.
    • By December 1942 facilities were established in remote locations across the US, as well as in Canada.
    • However, the superbomb was finally designed and conceptualized by a team of scientists at a top-secret laboratory in Los Alamos.
    • The Los Alamos team developed two types of bombs — one was uranium-based, which was later code-named ‘the Little Boy’ before it was dropped on Hiroshima; the other had a plutonium core.

    Looping-in nuclear physicists

    • The project brought together some of the country’s leading atomic experts as well as exiled scientists and physicists from Germany and other Nazi-occupied nations.
    • The team at Los Alamos was headed by J Robert Oppenheimer, a physics professor at the University of California, Berkeley.
    • Oppenheimer later came to be known as the “father of the atomic bomb”.
    • His team included famous Danish scientist Niels Bohr and Italian scientists Enrico Fermi.

    What were the repercussions of the Trinity Test?

    • New Mexico residents were pointedly not warned before the test, to ensure that it was carried out secretly.
    • Data collected by the New Mexico health department, which showed the adverse impact of radiation caused by the detonation, was ignored for years after the test.
    • A sudden rise in infant mortality was reported in the months after the explosion. Several residents also complained that the number of cancer patients went up after the Trinity Test.
    • The dust outfall from the explosion was expected to have travelled nearly 100 miles from the test site, posing a serious threat to residents in the area.
    • Many families complained that their livestock suffered skin burns, bleeding and loss of hair.

    Impact of bombing on Japan

    • The Hiroshima and Nagasaki bombings are known to have killed well over 200,000 people — many of whom succumbed to radiation poisoning in the weeks after the blasts.
    • The uranium bomb in Hiroshima on August 6, 1945, destroyed around 70 per cent of all buildings and caused around 140,000 deaths by the end of 1945.
    • The plutonium bomb explosion over Nagasaki, which took place three days later, killed 74,000 people that year, according to International Campaign to Abolish Nuclear Weapons (ICANW) data.
    • After seeing the destruction caused to the two Japanese cities, Oppenheimer publicly admitted that he regretted building a bomb that could cause an apocalypse.

    Nuclearisation of the world thus began

    • Seventy-five years after the Trinity Test, as many as nine countries around the world are currently in possession of nuclear weapons.
    • These include the US, the UK, Russia, France, India, China, Israel, Pakistan and North Korea.
    • At least eight countries have detonated over 2,000 nuclear test explosions since 1945.
    • The most recent instance of nuclear bomb test explosions conducted by India, were the series of five explosions done as part of the Pokhran-II tests in May 1998.
    • The first test, code-named Smiling Buddha, took place in May 1974.

  • Lancet’s analysis of population trends for 2017-2100

    When this century ends, India may no longer be a country of a billion, says a projection that appears in the online edition of the Lancet. The reference forecasts for China and India peaked before 2050 and both countries thereafter had steep declining trajectories.

    Try this question from CSP 2011:

    Q.India is regarded as a country with ‘Demographic Dividend’. This is due to

    (a) Its high population in the age group below 15 years

    (b) Its high population in the age group of 15-64 years

    (c) Its high population in the age group above 65 years

    (d) Its high total population

    World to see the peak

    • A new analysis published in The Lancet has projected that the world population will peak much earlier than previously estimated.
    • It projects the peak at 9.73 billion in 2064, which is 36 years earlier than the 11 billion peaks projected for 2100 by last year’s UN report World Population Prospects.
    • For 2100, the new report projects a decline to 8.79 billion from the 2064 peak.

    5 most populated countries

    • The five largest countries in 2100 are projected to be India, Nigeria, China, the U.S. and Pakistan.
    • However, these forecasts showed different future trajectories between countries.
    • Nigeria is forecast to have continued population growth through 2100 and was expected to be the second-most populous country by then.

    Predictions on India’s population

    • For India, the report projects a peak population of 1.6 billion in 2048, up from 1.38 billion in 2017.
    • By 2100, the population is projected to decline by 32% to 1.09 billion.
    • However, meeting UN Sustainable Goal Development targets, the peak would be earlier and see a population decline to 929 million.
    • Conventional wisdom is that though a decline in population is expected, it is expected to begin only around 2046.
    • The fall according to the latest 2019 assessment by the UNDP calculation, is expected to see India’s population settle at a little over 1.4 billion.

    Reasons for fall

    • The sharper fall is due to the assumption that all women globally will have much higher access to contraception and education.
    • This scenario will lead to a sharper reduction in the Total Fertility Rate, a metric that shows on average how many children a woman must have to keep replenishing the population.
    • A TFR is lower than 2.1leads to a decline in a country’s population.

  • Who are the Tangams?

    Last week Arunachal CM released a book titled “Tangams: An Ethnolinguistic Study Of The Critically Endangered Group of Arunachal Pradesh”.

    Try this question from CSP 2019:

    Q.Consider the following statements about Particularly Vulnerable Tribal Groups (PVTGs) in India:

    1. PVTGs reside in 18 States and one Union Territory.
    2. A stagnant or declining population is one of the criteria for determining PVTG status.
    3. There are 95 PVTGs officially notified in the country so far.
    4. Irular and Konda Reddi tribes are included in the list of PVTGs.

    Which of the statements given above are correct?

    (a) 1, 2 and 3

    (b) 2, 3 and 4

    (c) 1, 2 and 4

    (d) 1, 3 and 4

    Who are the Tangams?

    • The Tangams is a little-known community within the larger Adi tribe of Arunachal Pradesh and resides in the hamlet of Kugging in Upper Siang district’s Paindem circle.
    • In 1975, the community’s population was pegged at 2,000 spread across 25 villages.
    • From 2016 to 2020, a team from the Centre for Endangered Languages (CFEL) of Rajiv Gandhi University (RGU), carried out extensive field research and documented the community.
    • Their survey revealed that Tangams were now concentrated in only one village (Kugging), with only 253 reported speakers.
    • As per the UNESCO World Atlas of Endangered Languages (2009), Tangam — an oral language that belongs to the Tani group, under the greater Tibeto-Burman language family — is marked ‘critically endangered’.

    Why are there only a few speakers?

    • Kugging is surrounded by a number of villages inhabited by Adi subgroups such as Shimong, Minyongs, as well as the Buddhist tribal community of Khambas, among others.
    • To communicate with their neighbours over the years, the Tangams have become multilingual, speaking not just Tangam, but other tongues such as Shimong, Khamba and Hindi.
    • They rarely speak their own language now since their population is restricted to a single village. Moreover, the Tangams are relatively unknown — even within their state.
    • The village lacks proper infrastructure in all basic sectors of education, health, drinking water facilities, road and electricity. Roads have reached Kugging only in 2018.
    • Not a single person from the community has gone to university.

    Why are the languages at risk?

    • The diversity of languages has led various communities to depend on English, Assamese and colloquial variety of Hindi called Arunachalee Hindi as the link languages.
    • Many believe this shift has led to the loss of native languages of the tribal communities.
    • Even the numerically larger tribes like Nyishi, Galo, Mishmi, Tangsa etc. whose population exceed the ten thousand mark are also not safe from endangerment, hence marked unsafe.
    • The younger generation of these tribes especially in the urban areas has mostly discarded the use of their mother tongue.

  • Mapping: Islands of Polynesia

    How did the Polynesian peoples come to live on the far-flung islands of the Pacific? The question has intrigued researchers for centuries.

    The newscard contains some trivial facts. However, aspirants are advised to observe the map.

    Study on Polynesia

    • Norwegian explorer Thor Heyerdahl brought the topic to public attention when he sailed a balsa-wood raft called the Kon-Tiki from Peru to Polynesia in 1947.
    • His goal was to demonstrate such voyages were possible, supporting theories linking Polynesian origins to the Americas.
    • Decades of research in archaeology, linguistics and genetics now show that Polynesian origins lie to the west, ultimately in the islands of Southeast Asia.

    New evidence for American interlopers

    • A new study published in Nature reports genetic evidence of Native American ancestry in several Polynesian populations.
    • Other researchers have previously found evidence of indigenous American DNA in the genomes of the modern inhabitants of Rapa Nui.
    • Rapa Nui, also known as Easter Island, is the part of Polynesia closest to South America.
    • This suggests the “Amerindian” genetic component was likely introduced later via Chilean colonists.

  • Mapping: Mont Blanc

    The melting Mont Blanc glacier in the French Alps yielded a clutch of newspapers with banner headlines from when Indira Gandhi became India’s first and so far only woman Prime Minister in 1966.

    Try this MCQ

    Q.The Mont Blanc in the Alps can be located near the conflux of which of the following two countries?

    a)France and Spain

    b)France and Italy

    c)Spain and Italy

    d)Greece and Slovenia

    Mont Blanc

    • Mont Blanc is the second-highest mountain in Europe after Mount Elbrus. It is the highest mountain in the Alps and Western Europe.
    • It rises 4,808 m above sea level and is ranked 11th in the world in topographic prominence.
    • The mountain stands in a range called the Graian Alps, between the regions of Aosta Valley, Italy, and Savoie and Haute-Savoie, France.
    • It is the tallest peak in the Alps and the highest summit in Western Europe, hence its epithet the “Roof of Europe”.

  • ‘Churachandpur Mao Fault’ in Mizoram

    Mizoram’s zone of “scary” earthquakes is caught between two subterranean faults called the ‘Churachandpur Mao Fault’.

    Try this question from CSE Mains 2014:

    Q.Why are the world’s fold mountain systems located along the margins of continents? Bring out the association between the global distribution of Fold Mountains and the earthquakes and volcanoes.

    Churachandpur-Mao Fault (CMF)

    • The CMF is named after two places in Manipur and runs north-south into Myanmar along the border of Champhai.
    • The Mat Fault runs northwest-southeast across Mizoram, beneath river Mat near Serchhip.
    • It is defined by straight valleys; most prominent being between Kangpokpi and Maram region of Mizoram.
    • The fault takes a north-easterly trend from Maram where the fault zone is characterized by active landslides during the monsoon.

    Why study CMF?

    • Faults are discontinuities or cracks that are the result of differential motion within the earth’s crust.
    • Vertical or lateral slippage of the crust along the faults causes an earthquake.
