  • [Spiritual Tourism #1] PRASAD Cities- Ajmer and Amaravati

    Although the definition and purposes of Tourism is no longer restricted to Heritage and Pilgrimage cities- its definitely India’s USP due to its Civilizational legacy, and being the birthplace of many religions.

    In this series on Themes in Tourism Industry, we’ll start by taking a trip through History and Culture of Cities of Spiritual / Religious Importance. For its promotion Government of India has launched two schemes PRASAD and Swadesh Darshan for Development of Theme-Based Tourist Circuits. 

    About the PRASAD Scheme

    • PRASAD means Pilgrimage Rejuvenation and Spirituality Augmentation Drive
    • A 100% Centrally Sponsored Scheme under Tourism Ministry
      • Note that funds for any CSS is given to states in installments (20% at approval stage, 60% when 20% work done and rest 20% when 60% work is finished)
    • Provisions under the scheme include
      • Tourism Promotion and Tourist Ecosystem
      • Vocational Training for Tourists and Hospitality Business
        • Hunar se Rozgar tak (HSRT) and earn while you learn programs
      • Improving Tourist Infrastructure

    Provisions regarding Tourist Infrastructure in PRASAD

    • ATM, foreign currency exchange counters
    • Rail, road water transport
    • Green energy streetlights
    • Water adventure sports
    • First-aid centres, Wi-Fi hotspots, Parking facilities
    • Green landscaping, water fountains, walkways, furniture etc.
    • Removing encroachments

    PRASAD versus HRIDAY?

    • HRIDAY means Heritage City Development and Augmentation Yojana
    • While PRASAD is under Tourism ministry <note that Culture ministry is separate from Tourism ministry> while HRIDAY is under Urban Development Ministry
    • PRASAD cities are handpicked because their tourism is centered around faith, spirituality and religion. On the other hand, a HRIDAY city is chosen for its heritage status that goes beyond faith to include aspects of culture such as Architecture (Eg- Cave temples of Badami, Kakatiya Temples of Warangal)
    • HRIDAY is exclusively focused on Infrastructure that preserve the Heritage Character (Museums, Fairs, Festivals etc) , while PRASAD goes beyond that to include Vocational Training programmes and other things that make up Tourism Ecosystem
    • Common outcomes of both are:
      • Increase in Employment, Tourist Footfalls, Cleanliness of Heritage/Pilgrimage cities
      • Decrease in Pollution, Crime rates etc
    • There are 12 cities selected for both schemes, but there’s a considerable overlap in the sense that 10 cities are common to both. Only cities separate are:
      • Kamakhya in Assam and Kedarnath in Uttarakhand (PRASAD)
      • Badami in Karnataka and Warangal in Telangana
    • Lets take a tour of those common 10 cities and the other 2 specific to PRASAD.

  • Repatriation of Artifacts & Antiquities under Colonial Possession

    In previous blog of this series we learnt that our heritage under Colonial possession qualifies as an “illegal acquisition” as per international conventions. 

    So technically, countries like UK are indeed liable to return antiquities and heritage properties under their private or public possession. But politics aside, there are some other reasons due to which there has been little progress on restitution of Peacock Throne, or everyone’s favourite- the Koh-i-Noor diamond.

    International Conventions on returning colonial possessions

    1. UNESCO’s Convention on the Means of prohibiting and preventing the illicit import, export and transfer of ownership of cultural property (1970)
      • Newly independent states after World wars, were trying to recover important cultural objects that are mostly found in the museums of their former colonizing state.
      • Three main pillars: Protection against theft (Preventive Measure), Restitution Measures through Diplomatic channels, and International cooperation.
      • But the issue with this convention is that its mandate is not retroactive and most of the illegal acquisitions were made before 1970 before the fall of Colonialism.
      • Contemporary relevance: Monuments are being destroyed locally (IS in Syria or the Taliban in Afghanistan) can be taken out and protected for the sake of the whole world by a capable country under this convention. It can later be returned to the “source” countries when the conflict ends.
    2. UN General Assembly resolutions
      • UNGA has made successive resolutions on this matter
      • Deplored “the wholesale removal of Cultural Heritage, virtually without payment” as a result of colonial or Foreign Occupation
      • Unlike UNESCO’s convention- their mandates has been retroactive
      • Covered cultural property lost either as a consequence of
        1. Foreign or colonial occupation, or
        2. Through illicit traffic “prior” to the adoption of the 1970 Convention
      • Then why no success?
        • Covers cultural properties that are currently in safe places and open to the public, like museums, archives and libraries. Thus, it does not cover the equally important Private Sphere
        • CAG’s findings that Indian artifacts have reached foreign auction houses like Sotheby’s and Christie’s
        • Eg- Bonhams, the london private auctioneer, recently auctioned Tipu Sultan’s property against all efforts by India to claim its ownership over it.
        • Most of the personal wealth and possessions of the 18th century Mysore ruler including that of Tipu Sultan, is in the illegal private possession of families, descendants of British and Scottish soldiers <which particular soldier/general could we be referring to?>
      • Why no repatriation from Public Museums?
        • Cultural institutions like Public Museums have yet to acknowledge the full negative legacy of the colonial rulers.
        • While many of these museums are autonomous, when such demands are made on an International level, local governments do intervene and matter turns diplomatic and political.

    Why Repatriation of possessions is a just demand?

    1. Repatriation is already happening: Restitution of Jewish Artifacts by Nazis
      • Association of Art Museum Directors (AAMD) adopted a series of protocols to ensure that any work of art proven to be taken forcibly from a Jewish family during the Nazi regime should be returned to the rightful heirs
      • Between 1998 and 2006, 26 works in American museums were identified as being looted by the Nazis and were, in each case, restituted to the heirs
    2. Non-governmental actors succeeding on many levels— students resident in the U.K. — getting into the discussion around national cultural patrimony
      • Nigerian students demanding the return of the Benin bronzes looted from Nigeria at the time of the British imperial siege of the country in the late 19th century
      • Pressure generated so far has led for Cambridge University to remove the articles from Public display. It goes a long way into acknowledging the mistakes, if not outrightly returning the possessions.
      • Furthermore, few descendants of British Soldiers have shown the way by returning Nigerian Artifacts to their rightful owners, that was otherwise looted by their grandfathers in 19th century.

    Why are ex-Colonialists against repatriation?      

    1. They say that Encyclopedic museums of Europe and the U.S. are repositories of world art under one roof.
      • That they take care (by acting as protectors) of our global heritage, as art knows no boundaries
      • In this way they claim to be promoting international understanding of art.
      • Counter: This argument reeks of old European big-brother attitude that claims to be a superior civilization taking upon itself the task of correcting other civilizations.
    2. Objects were taken from countries such as Egypt, China, or India because none of these countries had the resources or the inclination to protect their own treasures
      • It was British officials who discovered, excavated or restored great sites such as Sanchi or Ajanta while there was no indigenous interest in preserving them at the time.
      • Counter: By this logic, they should return these artifacts to us, because now capable and resourceful enough to preserve the

    What are the “real” consequences of Repatriation on ex-Colonial countries?

    • Former colonizers would have to acknowledge various wrongs perpetrated by them on the colonies they ruled. This would result in a domino effect and not just restricted to repatriation of heritage objects, and could cause an International debacle and domestic shame.
    • Many of the biggest museums, especially the Louvre, the British Museum, and even some major American museums would get hollowed out of their collections

    So how do we resolve this issue?

    1. Museums of the Euro-American world could create a Long-term Loan programme
      • National Museum in New Delhi were to receive a long-term loan of Egyptian objects or 19th century American landscape paintings so that the National Museum too could begin to resemble an encyclopaedic museum of the West
    2. Seriously think about returning the ownership of objects back to the source countries
      • This could only happen if Western museums actually acknowledged the colonial past.
      • And simply recognising their role as “protectors” of, and not “owners” of global heritage.

  • Why would I buy the magazine when all the news is on the app & web?

    Hello,

    Here’s a valid concern/ legitimate query which we often receive on our mailboxes where the aspirants wonder – if all the news is available for FREE anyway, what’s the point behind buying the Civilsdigest magazine?

    Why even spend 50 bucks for a pdf when I am reading news daily on the FREE app and bookmarking important news to take them offline and revise without any internet access.

    OR

    Even if I do not have an android phone (since the Civilsdaily App is for android only), I can anyday go back on the NEWS tab on the website and read news filtered by calendar dates and that’s also super easy.

    Yes, it is. And you are right. You do not have to buy the magazine if these two amazing products are able to help you save time everyday and keep up with daily news that is focussed and important for your IAS Prep.

    So, buy the magazine only and only if

    #1. You find it convenient to read from a consolidated pdf which gives you a book-like feel and allows you to highlight specific words and points for easy recall

    #2. You value the time when you read things OFFLINE and do not want to be connected to internet and its interruptions while you are in DEEP STUDY mode

    #3. You are not very regular with news (because there is tons of static material to be covered) and love the comfort of a consolidated magazine just in case you miss some important bookmarks

    If you haven’t tried reading from our richly curated and nicely designed monthly magazines, we would invite you to try on one. FOR FREE.

    Click here to download the Edition #0

    It’s a 9 mb file and we would request you to be patient while you do so.

    If you like reading the FREE version… 

    We would request you to go to our Instamojo STORE and buy the rest of the editions for a princely sum of 50 bucks each!
