    Conservation of Sacred Grooves

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Sacred Grooves

    Mains level: Read the attached story

    India’s sacred groves are being gradually altered due to ever-expanding human populations, pollution and removal of biomass; effective conservation is the need of the hour to maintain their functional values

    What are Sacred Grooves?

    • Sacred groves of India are forest fragments of varying sizes, which are communally protected, and which usually have a significant religious connotation for the protecting community.
    • It usually consists of a dense cover of vegetation including climbers, herbs, shrubs and trees, with the presence of a village deity and is mostly situated near a perennial water source.
    • Sacred groves are considered to be symbols of the primitive practice of nature worship and support nature conservation to a great extent.
    • The introduction of the protected area category community reserves under the Wild Life (Protection) Amendment Act, 2002 has introduced legislation for providing government protection to community-held lands, which could include sacred groves.

    Historical references

    • Indian sacred groves are often associated with temples, monasteries, shrines, pilgrimage sites, or with burial grounds.
    • Historically, sacred groves find their mentions in Hindu, Jain and Buddhist texts, from sacred tree groves in Hinduism to sacred deer parks in Buddhism for example.
    • Sacred groves may be loosely used to refer to natural habitat protected on religious grounds.
    • Other historical references to sacred groves can be obtained in Vrukshayurveda an ancient treatise, ancient classics such as Kalidasa’s Vikramuurvashiiya.
    • There has been a growing interest in creating green patches such as Nakshatravana

    Regulation of activities in Sacred Grooves

    • Hunting and logging are usually strictly prohibited within these patches.
    • Other forms of forest usage like honey collection and deadwood collection are sometimes allowed on a sustainable basis.
    • NGOs work with local villagers to protect such groves.
    • Traditionally, and in some cases even today, members of the community take turns to protect the grove.

    Threats to such grooves

    • Threats to the groves include urbanization, and over-exploitation of resources.
    • While many of the groves are looked upon as abode of Hindu deities, in the recent past a number of them have been partially cleared for construction of shrines and temples.

    Total grooves in India

    • Around 14,000 sacred groves have been reported from all over India, which act as reservoirs of rare fauna, and more often rare flora, amid rural and even urban settings.
    • Experts believe that the total number of sacred groves could be as high as 100,000.
    • They are called by different names in different states:
    1. Sarna in Bihar
    2. Dev Van in Himachal Pradesh
    3. Devarakadu in Karnataka
    4. Kavu in Kerala
    5. Dev in Madhya Pradesh
    6. Devarahati or Devarai in Maharashtra
    7. Lai Umang in Maharashtra
    8. Law Kyntang or Asong Khosi in Meghalaya
    9. Oran in Rajasthan
    10. Kovil Kadu or Sarpa Kavu in Tamil Nadu

    What lies ahead?

    • The groves have great research value in in situ conservation of rare, endangered and threatened plant species.
    • It is high time that public awareness is created about the importance of these sacred groves, developmental activities are banned and the felling of trees or removal of any other vegetation is completely stopped.
    • This is possible only by way of enacting a special law for the protection and management of sacred groves.
    • As the management practices and other rituals vary from state to state, the concerned state governments may promulgate such an act as suitable for the state.
    • The idea should be to protect certain rare, endangered and threatened plant species in the era of global warming and climate change.

    Near Field Communication (NFC) technology for instant payments

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Near Field Communication (NFC)

    Mains level: Not Much

    Google Pay has recently launched a new feature in India, ‘Tap to pay for UPI’, in collaboration with Pine Labs. The feature makes use of Near Field Communication (NFC) technology.

    What is Near Field Communication (NFC)?

    • NFC is a short-range wireless connectivity technology that allows NFC-enabled devices to communicate with each other and transfer information quickly and easily with a single touch.
    • It makes possible to pay bills, exchange business cards, download coupons, or share a document.

    How does it work?

    • NFC transmits data through electromagnetic radio fields, to enable communication between two devices. Both devices must contain NFC chips, as transactions take place within a very short distance.
    • NFC-enabled devices must be either physically touching or within a few centimetres from each other for data transfer to occur.

    When did NFC tech start?

    • In 2004, consumer electronics companies, Nokia, Philips and Sony together formed the NFC Forum, which outlined the architecture for NFC technology to create powerful new consumer-driven products.
    • Nokia released the first NFC-enabled phone in 2007.

    How will this technology work with the recently launched feature, ‘Tap to pay for UPI’?

    • Google Pay has been the first among UPI apps to bring the Tap to Pay feature working on POS terminals.
    • It will allow users with UPI accounts configured on Google Pay to make payments just by tapping their NFC-enabled Android smartphones on any Pine Labs Android POS terminal.
    • Once users tap their phones on the POS terminal, it will automatically open the Google pay app with the payment amount pre-filled.
    • Users can then verify the amount and merchant name and authenticate the payment, using their UPI PIN.
    • The process is much faster compared to scanning a QR code or entering the UPI-linked mobile number which has been the conventional way till now.

    What are the other applications of NFC technology?

    • NFC tech has a wide range of applications besides driving payment services.
    • It is used in contactless banking cards to perform money transactions or to generate contact-less tickets for public transport.
    • Contactless cards and readers use NFC in several applications from securing networks and buildings to monitoring inventory and sales, preventing auto theft, keeping tabs on library books,
    • NFC is behind the cards that we wave over card readers in subway turnstiles and on buses to check tickets.
    • It is present in speakers, household appliances, and other electronic devices that we monitor and control through our smartphones.
    • With just a touch, NFC can also set up WiFi and Bluetooth devices in our homes, investopedia noted.
    • It also has an application in healthcare, to monitor patient stats through NFC-enabled wristbands.
    • NFC is used in wireless charging too.

    How safe is this technology?

    • NFC technology is designed for an operation between devices within a few centimetres from each other.
    • This makes it difficult for attackers to record the communication between the devices compared to other wireless technologies which have a working distance of several metres, according to the NFC forum, a non-profit industry association.
    • The user of the NFC-enabled device determines by the touch gesture which entity the NFC communication should take place with, making it more difficult for the attacker to get connected.
    • The security level of the NFC communication is by default higher compared to other wireless communication protocols.

    Where does it stand in comparison to other wireless technologies?

    • There are other wireless technologies available which are replacing cable-based connections.
    • The IrDa technology is a short range (a few metres) connection based on the exchange of data over infrared light where the two communication devices must be positioned within a line of sight.
    • Today, this technology is mainly used for remote control devices. For larger data communication with computer devices this technology was replaced by Bluetooth or WiFi connections.
    • However, for these technologies’ receiver devices need their own power supply due to the larger working distance.
    • Therefore, the receiving device cannot be powered by the radiofrequency (RF) field like in NFC, the NFC forum highlighted.
    • Another consequence of the larger working distance is the need for the user to configure their device and to pair them together for communication.

  • Trade Sector Updates – Falling Exports, TIES, MEIS, Foreign Trade Policy, etc.

    India to export Wheat

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Wheat

    Mains level: Indias export of agricultural commodities

    Russia and Ukraine account for about 25% of the world’s wheat exports. However, Russia’s invasion of Ukraine and the subsequent Western sanctions against Moscow have curtailed wheat supplies drastically.

    India eyeing the global wheat basket

    • As a result of War, many countries which were sourcing wheat mainly from these two nations are now in a dire need of alternatives.
    • India, the largest wheat producer after China, is reported to be eyeing the void.
    • The government plans to allow increased exports to cash in on the higher price of wheat in the international market.
    • With harvesting season (March to May) coinciding with the supply crunch, a bumper crop is also expected again this year.

    Global wheat scenario

    • While Russia and Ukraine exported 183 million tonnes (MT) and 91 MT of wheat, respectively, between 2017 and 2021, India exported just a fraction of its output, or just 12.6 MT, in the period.
    • Five other countries accounted for the bulk of wheat exports in this period, including the European Union (157 MT), the U.S. (125 MT), Canada (112 MT) and Australia (83 MT).
    • India, which had the second-highest wheat supply (including production, existing stocks and imports) in this period at 613 million tonnes, exported only 2% of this, with about 80% used for domestic consumption, and the rest stored.

    Impact of the war

    • Many countries in Africa, West Asia and Southeast Asia rely heavily on Russian and Ukrainian wheat.
    • Egypt, the biggest importer of wheat, sources 93% of its needs from the East European neighbors. Indonesia, the second-largest importer, has a 30% dependence on these two nations.
    • African nations such as Sudan (60% reliance), Tanzania (64%), Libya (53%), Tunisia (52%), and West Asian countries including Lebanon (77% dependency), Yemen (50%) and the UAE (42%) are also highly dependent on supplies from the two neighbors now at war.

    India’s focus markets

    • India is now focussing on exporting wheat to many nations such as Egypt, Turkey, Nigeria, Algeria, West Asia, Indonesia, Vietnam, Sri Lanka, Bangladesh, Thailand, the Philippines, Morocco and Tanzania.
    • To give impetus to the export promotion of wheat as well as to bring focus on the challenges and bottlenecks faced in production and export, APEDA has created a task group.

    Legal hurdles over Wheat Exports

    • If India decides to export wheat from its stocks, some developed nations may raise objections at the World Trade Organisation.
    • Already, in March, India was accused of exporting rice from its stocks.
    • India had replied that its rice exports were not from stocks set aside under the public stockholding programs.

    India’s consideration

    • The Supreme Court in the Right to Food case, observed that the peace clause adopted in WTO’s Bali Ministerial in 2014 does not prevent India from exporting foodgrains.
    • With the buffer stocks at hand, India should increase its wheat exports in order to stabilise global prices to the extent that it can.
    • It is also important because the countries that were dependent on Russia and Ukraine for their wheat are looking for an alternative source.

    Way ahead

    • There is a need to prioritise local prices and ensure adequate supplies for domestic consumption before deciding on the quantum of exports.
    • Ensuring the stability of prices in India and availability of grain for internal consumption should be of utmost priority to the Indian government
    • The government should plan this move in such a way that it does not impact local consumption.
    • A bumper crop of wheat is expected, so the government can procure enough for its distribution and buffer needs.
    • Further, as of now, there are no export restrictions, so farmers can also get the advantage of higher prices by selling the surplus to private traders for exports.

  • Modern Indian History-Events and Personalities

    Raja Ravi Varma and his Arts

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Raja Ravi Varma

    Mains level: Not Much

    Raja Rai Varma’s Draupadi Vastraharan is expected to fetch between Rs 15 and Rs 20 crore at an auction.

    Who was Raja Ravi Varma?

    • Raja Ravi Varma was born in April 1848 in Kilimanoor, Kerala, to a family which was very close to the royals of Travancore.
    • Often referred to as the father of modern Indian art, he is widely known for his realistic portrayal of Indian gods and goddesses.
    • While he majorly painted for the royalty, he is also credited for taking art to the masses with his prints and oleographs.
    • At a young age, he would draw animals and everyday scenes on the walls in indigenous colours made from natural materials such as leaves, flowers and soil.
    • His uncle, Raja Raja Varma, noticed this and encouraged his talent.
    • Patronised by Ayilyam Thirunal, the then ruler of Travancore, he learnt watercolour painting from the royal painter Ramaswamy Naidu, and later trained in oil painting from Dutch artist Theodore Jensen.

    How he became an artist of the royals?

    • Varma became a much sought-after artist for the aristocrats and was commissioned several portraits in late 19th century.
    • Arguably, at one point, he became so popular that the Kilimanoor Palace in Kerala opened a post office due to the sheer number of painting requests that would come in for him.
    • He travelled across India extensively, for work and inspiration.

    Fame as a notable painter

    • Following a portrait of Maharaja Sayajirao of Baroda, he was commissioned 14 Puranic paintings for the Durbar Hall of the new Lakshmi Vilas Palace at Baroda.
    • Depicting Indian culture, Varma borrowed from episodes of Mahabharata and Ramayana for the same.
    • He also received patronage from numerous other rulers, including the Maharaja of Mysore and Maharaja of Udaipur.
    • As his popularity soared, the artist won an award for an exhibition of his paintings at Vienna in 1873.
    • He was also awarded three gold medals at the World’s Columbian Exposition in Chicago in 1893.

    Nature of his artforms

    • Much of his celebrated art also borrows heavily from Indian mythology.
    • In fact, he is often credited with defining the images of Indian gods and goddesses through his relatable and more realistic portrayals often painted with humans as models.
    • The depictions include Lakshmi as the goddess of wealth, Saraswati as the goddess of knowledge and wisdom, and Lord Vishnu with his consorts, Maya and Lakshmi.

    How he took Indian art to the masses?

    • Raja Ravi Varma aspired to take his art to the masses and the intent led him to open a Lithographic Press in Bombay in 1894.
    • The idea, reportedly, came from Sir T Madhava Rao, former Dewan of Travancore and later Baroda, in a letter where he pointed out to Varma that since it was impossible for him to meet the large demand for his work, it would be ideal for him to send some of his select works to Europe and have them produced as oleographs.
    • Varma, instead, chose to establish a printing press of his own.
    • The first picture printed at Varma’s press was reportedly The Birth of Shakuntala, followed by numerous mythological figures and saints such as Adi Shankaracharya.

  • Tribes in News

    Tripura’s Darlong community in included in ST List

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Darlong Tribes

    Mains level: Scheduled Tribes and issues

    The Lok Sabha recently passed a bill to amend a constitutional order to include Darlong, a tribal clan in Tripura which was among the generic Halam community till now, in the list of Scheduled Tribes (ST).

    Who are Darlongs?

    • Darlong is a tribal community of 11,000 people.
    • Despite its small population, the community has a high prevalence of education, cultural activities and members of the community are serving in different high positions in the local administration.
    • Darlongs, despite being Scheduled Tribes, were never given ST certificates.
    • Since they were considered a generic tribe under the Kuki community, they were handed their tribal certificates as members of ‘Kuki’ community.
    • The subsequent identity crisis among them, especially Darlong youths, who were equipped with modern education, culminated in the demand for a separate statutory identity of their own in 1995.
    • The group is a small tribal clan but has produced a high number of educated people proportionate to its population in the state.
    • People from the Darlong community, like many other tribal communities, are now serving in high positions in the state administration, academia, and public services.
    • Tribal musicologist and Rosem (tribal instrument) maestro Thanga Darlong was conferred the prestigious Padma Shri award a few years back for his contribution to culture.

    Why is tribal identity a big issue in Tripura?

    • Out of 37 lakh people of Tripura, nearly 30 per cent are tribals, who mostly live in areas under jurisdiction of the Tripura Tribal Areas Autonomous District Council (TTAADC).
    • They are spread in patches across all eight districts and covering 70 per cent of the state’s geographical area.
    • The state saw tribals become minority in their own state due to arrival of East Pakistani refugees who fled their country.
    • Tribal identity is a major issue in Tripura, which is also one of the major subjects dominating the state politics now.
    • There is rising demand of Greater Tipraland – a proposed separate state for Tiprasa or Tripuris (tribal and non-tribal) living in the state.

    Back2Basics: Tribes of Tripura

    • Tripura, the tiny Northeast state of 37 lakh people houses 19 tribal communities.
    • These include Tripuri or Debbarma, Reangs or Brus, Jamatia, Noatia, Uchoi, Chakma, Mog, Lushai, Kuki, Munda, Kour, Oram, Santhal, Bhil, Bhutia, Chaimar or Sermai, Garo, Khasi, Lepcha and Halam.
    • Many of these communities are further divided into sub-tribes.
    • For example, Kukis have nearly 17-18 sub-tribes within the community.
    • It is an umbrella tribal community including many smaller clans like Khasi, Lushai, Hmars and other generic clans.
    • In course of time, Lushai, Hmar, Garo etc. came out of Kuki as separate communities.
    • Halam community also has several sub-tribes such as Rangkhawl, Ranglong, Dab, Chaimar or Sermai, Bong, Korbong, Harbong, Bongcher etc.

  • ISRO Missions and Discoveries

    What is Project NETRA?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Project NETRA

    Mains level: Space Debris

    The Indian Space Research Organisation (ISRO) is building up its orbital debris tracking capability by deploying new radars and optical telescopes under the Network for Space Objects Tracking and Analysis (NETRA) project.

    Project NETRA

    • The project will give India its own capability in space situational awareness (SSA) like the other space powers — which is used to ‘predict’ threats from debris to Indian satellites.
    • NETRA’s eventual goal is to capture the GEO, or geostationary orbit, scene at 36,000 km where communication satellites operate.
    • The initial SSA will first be for low-earth orbits or LEO which have remote-sensing spacecraft.
    • Under NETRA the ISRO plans to put up many observational facilities: connected radars, telescopes; data processing units and a control centre.
    • They can, among others, spot, track and catalogue objects as small as 10 cm, up to a range of 3,400 km and equal to a space orbit of around 2,000 km.
    • The NETRA effort would make India a part of international efforts towards tracking, warning about and mitigating space debris.

    What NETRA consists of?

    • In the plans are a high-precision, long range telescope in Leh and a radar in the North East.
    • Along with them, we will also use the Multi-Object Tracking Radar (MOTR) that we have put up at the Satish Dhawan Space Centre in Sriharikota, and the telescopes at Ponmudi and Mount Abu to get a broad SSA picture.
    • NORAD, or the North American Aerospace Defense Command, is an initiative of the U.S. and Canada that shares selective debris data with many countries.
    • The new SSA centre would consolidate debris tracking activities that are now spread across ISRO centres.
    • Currently there are 15 functional Indian communication satellites in the geostationary orbit of 36,000 km; 13 remote sensing satellites in LEO of up to 2,000 km; and eight navigation satellites in medium earth orbits.

    Why Space debris matters?

    • Space junk or debris consists of spent rocket stages, dead satellites, fragments of space objects and debris resulting from ASAT.
    • Hurtling at an average speed of 27,000 kmph in LEO, these objects pose a very real threat as collisions involving even centimetre-sized fragments can be lethal to satellites.
    • Last year, ISRO monitored 4,382 events in LEO and 3,148 events in the geostationary orbit where space objects closely approached Indian assets.
    • Fragments from the Fengyun-1C satellite (part of the anti-satellite test (ASAT) by China in 2007) and the Cosmos 2251-Iridium satellite collision in 2009 accounted for the maximum number of these threats.
    • The observations also covered 84 “close approaches of less than one km” between Starlink satellites and Indian assets.

    Enhancing Space situational awareness (SSA)

    • India, as a responsible space power, should have SSA as a part of a national capability, as in the U.S. This is a vital requirement for protecting our space assets and a force multiplier.
    • The SSA has a military quotient to it and adds a new ring to the country’s overall security.
    • It uses satellites, ground and air radars to secure its two countries against attacks from air, space or sea.
    • With long-range tracking radars, the SSA also provides us the capability of an early warning system against ballistic missiles coming in at a height.
    • Apart from radars and telescopes, he said India should also think of deploying satellites that track other satellites — as the U.S. and other space powers had done.
    • Combined with other elements of military intelligence SSA would help us to understand motives behind any suspicious orbit changes of other satellites and to know if they were spying on or harming our spacecraft.

  • Start-up Ecosystem In India

    Startup India Initiative and its Success

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Startup India Initiative

    Mains level: Success of the scheme

    A research, reviewing India’s entrepreneurial policy Startup India, affirmed its positive impact in reducing regional entrepreneurial disparities.

    Startup India Initiative

    • The Startup India campaign was first announced by PM Modi during his speech on 15 August 2015 address from the Red Fort.
    • The action plan for this initiative is focusing on three areas:
    1. Simplification and Handholding.
    2. Funding Support and Incentives.
    3. Industry-Academia Partnership and Incubation.
    • An additional area relating to this initiative is to discard restrictive States Government policies within this domain, such as License Raj, Land Permissions, Foreign Investment Proposals, and Environmental Clearances.
    • It was organized by the Department for promotion of industry and internal trade (DPI&IT).

    The success of the scheme

    • Minister for Commerce and Industry has informed the Lok Sabha that the entrepreneurial portal had more than 65,000 startups registered.
    • Of which, 40 attained the ‘unicorn’ status in the last twelve months, bringing the total as of date to 90.
    • India now ranks third among global startup eco-systems.
    • The networking, training and mentoring facilities provided by Startup India alongside entrepreneurship outreach campaigns in tier-2 and tier-3 cities, helped address regional entrepreneurial disparities in India.

    Limitations to its success

    (1) Heavy concentration in megacities

    • Entrepreneurship continues to be “highly concentrated” in three megacities, namely, Mumbai, Bengaluru and Delhi NCR.
    • India’s venture capital industry is also clustered in and around these three cities.
    • Such concentration can lead to increased economic inequality and hinder emergence of entrepreneurs from industries other than those belonging to the clusters.

    (2) Narrow Representation

    • The Startup India Action Plan document has no mention of the words ‘caste’, ‘tribe’, ‘marginalised’, ‘indigenous’ or ‘social group’.
    • Additionally, the policy’s reliance on technology does not take into consideration India’s digital divide, especially with respect to urban and rural areas.

    (3) Few Women in the industry

    • There is an under-representation of women and marginalized caste groups in the national startup ecosystem.

    Dedicated measures to support Women

    • 10% of the fund in the Fund of Funds operated by Small Industries Development Bank of India (SIDBI) has been reserved for women-led startups.
    • Further, all the alternate investment funds where the SIDBI takes equity have been mandated to contribute 20% in business which are women led.
    • There is a capacity-building program and a dedicated webpage for women on the portal.

    Way ahead

    • There is a need for policies and progressive strategies from governments to encourage startups and provide access and assistance in key areas including tax clarity, incubation, affordability and licensing.
    • In any case, governments should be well prepared and dedicated to creating a culture of startups to impact the entrepreneurial ecosystem in their cities, countries and citizens.

    Detecting Microplastics in Human Blood

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Microplastics

    Mains level: Microplastics Contamination

    A study by researchers from The Netherlands has found Microplastics in blood samples. About half of these were PET (polyethylene tertraphthalate) plastics, which is used to make food grade bottles.

    What are Microplastics?

    • Microplastics are tiny bits of various types of plastic found in the environment.
    • The name is used to differentiate them from “macroplastics” such as bottles and bags made of plastic.
    • There is no universal agreement on the size of microplastics. It defines microplastic as less than 5mm in length.
    • However, for the purposes of this study, since the authors were interested in measuring the quantities of plastic that can cross the membranes and diffuse into the body via the blood stream.
    • Hence they agreed on an upper limit on the size of the particles as 0.0007 millimetre.

    What were the plastics that the study looked for in the blood samples?

    • The study looked at the most commonly used plastic polymers.
    • These were polyethylene tetraphthalate (PET), polyethylene (used in making plastic carry bags), polymers of styrene (used in food packaging), poly (methyl methylacrylate) and poly propylene.
    • They found a presence of the first four types.

    Significance of the study

    • Making a human health risk assessment in relation to plastic particles is not easy, perhaps not even possible, due to the lack of data on exposure of people to plastics.
    • In this sense, it is important to have studies like this one.
    • The authors of the paper also remark that validated methods to detect the tiny (trace) amounts of extremely small-sized (less than 10 micrometre) plastic particles are lacking.
    • Hence this study, which builds up a methods to check the same, is important.

    Health hazard of microplastics

    • It is not yet clear if these microplastics can cross over from the blood stream to deposit in organs and cause diseases.
    • The report point out that the human placenta has shown to be permeable to tiny particles of polystyrene ( 50, 80 and 24 nanometre beads).
    • Experiments on rats where its lungs were exposed to polystryrene spheres (20 nanometre) led to translocation of the nanoparticles to the placental and foetal tissue.
    • Oral administration of microplastics in rats led to accumulation of these in the liver, kidney and gut.
    • Further studies have to be carried out to really assess the impact of plastics on humans.
