    Prelims level: Mandarin Duck, Dibru Saikhowa NP

    Mains level: Not Much

    A rare Mandarin duck was observed floating in the Maguri-Motapung beel (or wetland) in Assam’s Tinsukia district for over a week is spectacular.

    Mandarin duck

    IUCN status: Least Concerned

    • Considered the most beautiful duck in the world, the Mandarin duck, or the (Aix galericulata) was first identified by Swedish botanist, physician and zoologist Carl Linnaeus in 1758.
    • The eBird website, a platform that documents birds world over, describes it as a “small-exotic looking bird” native to East Asia.
    • It’s very beautiful, with majestic colours and can be spotted from a distance.

    Its habitat and breeding

    • The migratory duck breeds in Russia, Korea, Japan and northeastern parts of China. It now has established populations in Western Europe and America too.
    • In 2018, when a Mandarin duck was spotted in a pond in New York City’s Central Park, it created a flutter among local residents.
    • It was recorded in 1902 in Dibru River in the Rongagora area in Tinsukia.

    About Maguri beel

    Farakka ‘lock’ and Hilsa Fish

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Farakkha Barrage, Hilsa fish

    Mains level: Not Much

    It has been reported that an old project to facilitate the movement of Hilsa upstream along the Ganga to its spawning grounds of yore may come to fruition this year.

    What is the news?

    • Back in February 2019, the government had unveiled a project to redesign the navigation lock at the Farakka Barrage at a cost of Rs 360 crore to create a “fish pass” for the Hilsa.

    Hilsa Fish

    • In scientific parlance, the Hilsa (Tenualosa ilisha) is an anadromous fish.
    • It lives most of its life in the ocean, but during the rainy season, the Hilsa moves towards the estuary, where the rivers of India and Bangladesh meet the Bay of Bengal.
    • A large part of the shoal travels upstream in the Padma and the Ganga — some are known to move towards the Godavari, and there are records of Hilsa migration to the Cauvery.
    • Culinary lore has it that the fish that travel the farthest upstream have the best combination of the flavours of the sea and the river.

    d) 1, 2 and 3

    Obstructions created by Farakka Barrage

    • Historical records also show that until the 1970s, the Hilsa would swim the Ganga upstream to Allahabad — and even to Agra.
    • But the Farakka Barrage, which became operational on the Ganga in 1975, disrupted the westward movement of the Hilsa.
    • The barrage had a navigation lock that stopped the fish from swimming upstream beyond Farakka.
    • In Buxar on the border of Bihar and Uttar Pradesh, the last recorded catch of the Hilsa was made 32 years ago.
    • The role of the Farakka Barrage in disrupting the Hilsa’s journey is well documented and has been discussed in Parliament as well.
    • On August 4, 2016, then Union Water Resources Minister told Lok Sabha about plans to create “fish ladders” to help the fish navigate the obstacle posed by the barrage.

    Fish ladders/fishways/fish passes

    • Fish passes — also known as fish ladders or fishways — aim to assist fish in crossing obstacles presented by dams and barrages.
    • They usually consist of small steps that allow the fish to climb over the obstacles and enable them to reach the open waters on the other side.

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Adam's Bridge

    Mains level: NA

    In possibly a first, Indian scientists will undertake a scientific expedition to date the chain of corals and sediments forming the Ram Setu.

    Try this PYQ:

    Ram Setu

    • Also known as Adam’s bridge, Ram Setu is a 48-km long bridge-like structure between India and Sri Lanka.
    • It finds mention in the Ramayana but little about its formation is known or proven, scientifically.

    What is the underwater archaeological project at Ram Setu?

    • The National Institute of Oceanography (NIO) will undertake a three-year scientific project.
    • The idea is to see whether Ram Setu is a man-made structure or not.
    • The most important aspect of the project is to establish its age, scientifically.
    • The explorers will apply a number of scientific techniques while attempting to date the Ram Setu, study its material composition, outline the sub-surface structure along with attempting to excavate remnants or artefacts, if any, from the site.
    • Once it is known, the information can be verified and co-related with its mention in the Ramayana and similar scriptures.

    How is the project planned?

    • An initial survey will make use of underwater photographs to check if any habitation remains inundated in the area. A geophysical survey will be performed to understand the structure.
    • Over the years, several kinds of depositions, including sand, have covered the actual structure. Initially, only physical observation, and no drilling, will be done.
    • NIO operates two oceanographic vessels – RV Sindhu Sankalp (ability to go up to and remain 56 metres underwater) and RV Sindhu Sadhana (ability to go up to and remain 80 metres underwater).
    • For collecting core samples at greater depths and for bathymetry purposes, Sindhu Sadhana will be deployed for the Ram Setu project.

    Two of the planned tests:

    1. Side-scan SONAR — Will provide bathymetry which is similar to studying the topography of a structure on land. Soundwaves signals will be sent to the structure which will provide an outline of the physical structure of the Ram Setu.
    2. Silo seismic survey – Mild earthquake-like tremor shocks will be sent at shallow depths close to the structure. These energized shockwaves are capable of penetrating into the structure. The reflected or refracted signals will be captured by instruments that will provide sub-surface structure.

    Significance of such exploration

    • India has a vast coastline of over 7,500 kilometres.
    • Oceans are a treasure trove of the past records — climate, evolutionary changes of the underwater fauna, coastal lives, habitations, settlements and civilizations.
    • Of these, the sea-level changes remain the most significant of all with respect to climate studies.
    • History has records of sailors who set out on unknown voyages to later discover new lands and islands.
    • They ventured into deep seas even before the advent of the Global Positioning System (GPS).
    • Using such underwater exploration studies, scientists say that it is possible to trace numerous ship-wreckages and remains from the past.
    • Studies of ship wreckage, artefacts or remains could reveal a lot of information.

    Recently a 60000 YO submerged forest was explored off the Alabama coast in the USA.

    Has India undertaken underwater archaeological explorations?

    • A part of Dwarka, along with coastal Gujarat, is underwater, confirming the sea-level rise.
    • The NIO has been studying this site, and so far, traced large amounts of scattered stones which were retrieved at the depth between three to six metres beneath.
    • Stone anchors, too, were found at the site, suggesting it to be part of an ancient harbour.
    • In the past, NIO had initiated studies to trace the missing shore temples of Mahabalipuram in Tamil Nadu.
    • Presently, several ship wreckage studies, including the one-off the Odisha coast, are going on.

    Places in the news: New Anubhava Mantapa

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Kalyana Chalukya Style of Architecture

    Mains level: Temple Architecture of India

    Karnataka CM has laid the foundation stone for the ‘New Anubhava Mantapa’ in Basavakalyan, the place where 12th-century poet-philosopher Basaveshwara lived for most of his life.

    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.

    Who was 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 find 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.

    The New Anubhava Mantapa

    • The New Anubhava Mantapa, as envisaged now, will be a six-floor structure in the midst of the 7.5-acre plot and represent various principles of Basaveshwara
    • It will showcase the 12th Century Anubhava Mantapa (often referred to as the “first Parliament of the world”) established by him in Basavakalyan where philosophers and social reformers held debates.
    • The building will adopt the Kalyana Chalukya style of architecture.
    • The grand structure supported by 770 pillars will have an auditorium with a seating capacity of 770 people.
    • It is believed that 770 Sharanas (followers of Basaveshwara) led the Vachana reformist movement in the 12th Century.
    • The basement is designed for a Dasoha Bhavana (dining hall) where around 1,500 people eat together. On its top, the structure would have a Linga placed on a large pedestal.
    • The project also envisages a state-of-the-art robotic system, open-air theatre, modern water conservation system, terrace garden, library, research centre, prayer hall, yoga centre and so on.

    Back2Basics: Kalyana Chalukya Style of Architecture

    • It is the distinctive style of ornamented architecture that evolved during the rule of the Western Chalukya Empire in the Tungabhadra region of modern central Karnataka.
    • These monuments, regional variants of pre-existing Dravida (South Indian) temples, form a climax to the wider regional temple architecture tradition called Vesara or Karnata Dravida.
    • They are either Ekakuta (one mandapa of one shrine) or Dvikuta (a common hall attached to two shrines).
    • The style has characters of both the Northern as well as Dravidian temple architecture.
    • This combination of both of these styles is known as Vesara Style, also Central Indian Style, which is represented by the Hoysala Temples.
    • Most of the temples of the Western Chalukyas are dedicated to Shiva, some of them dedicated to Vishnu and Jain Tirthankars also.
