    (c) 1 and 3 only

    (d) 1, 2, 3 and 4

    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 news: Sundarban Biosphere Reserve

    Indian Sunderbans, which is part of the largest mangrove forest in the world, is home to 428 species of birds, a recent publication of the Zoological Survey of India (ZSI) States.

    Sundarban Biosphere Reserve

    (a) Biosphere reserves

    (b) National parks

    (c) Wetlands declared under Ramsar convention

    (d) Wildlife sanctuaries

    Harike Wetland

    • Harike Wetland also is the largest wetland in northern India in the border of Tarn Taran Sahib district and Ferozepur district of Punjab.
    • The wetland and the lake were formed by constructing the headworks across the Sutlej River in 1953.
    • The headworks is located downstream of the confluence of the Beas and Sutlej rivers just south of Harike village.
    • The rich biodiversity of the wetland which plays a vital role in maintaining the precious hydrological balance in the catchment with its vast concentration of migratory fauna.
    • It was accorded as a wetland in 1990, by the Ramsar Convention, as one of the Ramsar sites in India, for conservation, development and preservation of the ecosystem.

    Back2Basics: Ramsar Convention

    • The Convention on Wetlands of International Importance (better known as the Ramsar Convention) is an international agreement promoting the conservation and wise use of wetlands.
    • It is the only global treaty to focus on a single ecosystem.
    • The convention was adopted in the Iranian city of Ramsar in 1971 and came into force in 1975.
    • Traditionally viewed as a wasteland or breeding ground of disease, wetlands actually provide fresh water and food and serve as nature’s shock absorber.
    • Wetlands, critical for biodiversity, are disappearing rapidly, with recent estimates showing that 64% or more of the world’s wetlands have vanished since 1900.
    • Major changes in land use for agriculture and grazing, water diversion for dams and canals and infrastructure development are considered to be some of the main causes of loss and degradation of wetlands.

  • Great Green Wall (GGW) Project

    The Great Green Wall (GGW) Project to address desertification, land degradation and climate change in the Sahel region of Africa has hit a new low due to funds crunch.

    Note the countries swept by the GGW project on the African map.

    GGW Project

    • The Great Green Wall project is conceived by 11 countries located along the southern border of the Sahara and their international partners, is aimed at limiting the desertification of the Sahel zone.
    • Led by the African Union, the initiative aims to transform the lives of millions of people by creating a mosaic of green and productive landscapes across North Africa.
    • The initial idea of the GGW was to develop a line of trees from east to the west bordering the Saharan Desert.
    • Its vision has evolved into that of a mosaic of interventions addressing the challenges facing the people in the Sahel and the Sahara.

    Why was such project incepted?

    • The project is a response to the combined effect of natural resources degradation and drought in rural areas.
    • It aimed to restore 100 million hectares of degraded land by 2030; only four million hectares had been restored between 2007 and 2019.
    • It is a partnership that supports communities working towards sustainable management and use of forests, rangelands and other natural resources.
    • It seeks to help communities mitigate and adapt to climate change, as well as improve food security.

  • Management Effectiveness Evaluation of Protected Areas

    Minister for Environment, Forest and Climate Change has released Management Effectiveness Evaluation (MEE) of 146 national parks and wildlife sanctuaries in the country.

    Map the protected areas mentioned in the newscard in your Atlas.

    MEE Survey

    • MEE is a very important document that provides valuable guidance on various aspects of wildlife and protected area expand MEE of Marine Protected Areas.
    • In order to assess the efficacy of Protected Areas, evaluation of management effectiveness was required.
    • MEE has emerged as a key tool for PA managers and is increasingly being used by governments and international bodies to understand the strengths and weaknesses of the protected area management systems.
    • The results of the present assessment are encouraging with an overall mean MEE score of 62.01% which is higher than the global mean of 56%.
    • With this round of evaluation, MoEFCC successfully completed one full cycle of evaluating all terrestrial National Parks and Wildlife Sanctuaries of the country from 2006 to 2019.

    India has systematically designated its Protected Areas in four legal categories — National Parks, Wildlife Sanctuaries, Conservation Reserves and Community Reserves under the Wildlife (Protection) Act, 1972.

    Areas surveyed

    • Under the WP 1972 Act, India has 903 formally designated Protected Areas with total coverage of 1,65,012.6 square km.
    • Among these are 101 National Parks, 553 Wildlife Sanctuaries, 86 Conservation Reserves and 163 Community Reserves.
    • For the survey, 146 National Parks and Wildlife Sanctuaries across 29 states and Union territories were evaluated.

    Highlights of the MEE

    • Tirthan Wildlife Sanctuary and Great Himalayan National Park in Himachal Pradesh have performed the best among the surveyed protected areas.
    • The Turtle Wildlife Sanctuary in Uttar Pradesh was the worst performer in the survey.

  • Places in the news: New Anubhava Mantapa

    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.

    Examples: Truketshwara Temple, Gadag; Kasivisvesvara Temple, Lakkundi
