    Asian Waterbird Census (AWC) 2021

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Asian Waterbird Census (AWC) 2021

    Mains level: Wetland conservation in India

    The two-day Asian Waterbird Census-2020 was recently held in Andhra Pradesh.

    Anyone can participate!

    By using eBird and filling an additional site form, one can take part in this multi-country effort to document the state of our wetlands and waterbirds.  To take part one simply visits a wetland and count the birds he/she see there.

    Asian Waterbird Census

    • The Asian Waterbird Census (AWC) takes place every January.
    • The AWC was started in 1987, and many birders were initiated into bird counting and monitoring through this project.
    • This citizen-science event is a part of the global International Waterbird Census (IWC) that supports the conservation and management of wetlands and waterbirds worldwide.
    • The data collected each year is shared by Wetlands International with global conservation organisations such as IUCN and Ramsar Convention.

    Why need such census?

    • Waterbirds are one of the key indicators of wetlands health.
    • Wetlands provide feeding, resting, roosting and foraging habitats for these charismatic species.

    AWC in India

    • In India, the AWC is annually coordinated by the Bombay Natural history Society (BNHS) and Wetlands International.
    • BNHS is a non-government Organisation (NGO) founded in the year 1883.
    • It engages itself in the conservation of nature and natural resources and also in the research and conservation of endangered species.
    • Its mission is to conserve nature, primarily biological diversity through action based on research, education and public awareness.

    Back2Basics: Waterbirds

    • The term water bird, alternatively waterbird or aquatic bird is used to refer to birds that live on or around water.
    • In some definitions, the term is especially applied to birds in freshwater habitats, though others make no distinction from birds that inhabit marine environments.
    • Also, some water birds are more terrestrial or aquatic than others, and their adaptations will vary depending on their environment.
    • These adaptations include webbed feet, bills, and legs adapted to feed in the water, and the ability to dive from the surface or the air to catch prey in water.

    Know the scientist: Dmitri Mendeleev

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Dmitri Mendeleev, Periodic table

    Mains level: NA

    Mendeleev was a Russian chemist and inventor who formulated the Periodic Law and the Periodic Table of Elements.

    Chemistry can, no wonder, find their place in exam if core Biology could do in 2020 CSP.

    Q.Which of the following statements is/are correct regarding the general difference between plant cells and animal cells?

    1. Plant cells have cellulose cell walls whilst animal cells do not.
    2. Plant cells do not have plasma membrane unlike animals cells which do
    3. Mature plant cell has one large vacuole whilst animal cell has many small vacuoles

    Select the correct answer using the given code below-

    (a) 1 and 2 only

    (b) 2 and 3 only

    (c) 1 and 3 only

    (d) 1, 2 and 3

    Dmitri Mendeleev

    • Mendeleev was born in the Siberian town of Tobolsk.
    • In 1861, Mendeleev published a textbook named Organic Chemistry, which won him the Demidov Prize of the Petersburg Academy of Sciences.
    • While explaining the chemical and physical properties of elements, he discovered similarities in the progression of atomic weights.
    • He found that the order of atomic weights could be used to arrange the elements within each group and the groups themselves.
    • Thus, Mendeleev formulated the periodic law. His Osnovy khimii (The Principles of Chemistry) became a classic, running through many editions and many translations.

    The Periodic Law

    • Using the Periodic Law, Mendeleev developed a systematic table of all the 63 elements then known.
    • He even predicted the locations of unknown elements together with their properties within the periodic table.
    • When these predicted elements, notably gallium ( 1875), scandium (1879), and germanium (1886) were discovered, Mendeleev Periodic Table began to gain wide acceptance.
    • Incidentally, in 1870, German chemist Julius Lothar Meyer also published a paper describing the same organisation of elements as Mendeleev’s. But the latter is given credit for the table.
    • In all, Mendeleev predicted 10 new elements, of which all but two turned out to exist. Element 101 is named Mendelevium in his honour.

    Grand Ethiopian Renaissance Dam

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Grand Ethiopian Renaissance Dam

    Mains level: Horn of Africa Region

    Ethiopia, Sudan and Egypt have agreed on to resume negotiations to resolve their decade-long complex dispute over the Grand Renaissance Dam hydropower project in the Horn of Africa.

    Note: You never know when UPSC might switch map based questions away from the Middle East and SE Asia.

    Considering this news, the UPSC may ask a prelim question based on the countries swept by River Nile/ various dams constructed/ landlocked countries in the African continent etc.

    [Burning Issue] Ethiopian Crisis and the Geopolitics

    Grand Ethiopian Renaissance Dam

    • Spearheaded by Ethiopia, the 145-meter-tall (475-foot-tall) Grand Renaissance Dam hydropower project, when completed, will be Africa’s largest.
    • Its construction was initiated in 2011 on the Blue Nile tributary of the river that runs across one part of Ethiopia.
    • The Nile is a necessary water source in the region and Egypt has consistently objected to the dam’s construction, saying it will impact water flow.
    • The long-standing dispute has been a cause of concern for international observers who fear that it may increase conflict between the two nations and spill out into other countries in the Horn of Africa.

    What is the dispute about?

    • The Nile, Africa’s longest river, has been at the centre of a decade-long complex dispute involving several countries that are dependent on the river’s waters.
    • At the forefront of this dispute are Ethiopia and Egypt, with Sudan having found itself dragged into the issue.
    • The main waterways of the Nile run through Uganda, South Sudan, Sudan and Egypt, and its drainage basin runs through several countries in East Africa, including Ethiopia.

    Concerns over the dam

    • Given the dam’s location on the Blue Nile tributary, it would potentially allow Ethiopia to gain control of the flow of the river’s waters.
    • Egypt lies further downstream and is concerned that Ethiopia’s control over the water could result in lower water levels within its own borders.
    • In addition, Egypt proposed a longer timeline for the project over concerns that the water level of the Nile could dramatically drop as the reservoir fills with water in the initial stages.
    • Sudan’s location between Egypt up north and Ethiopia down south has caused it to become an inadvertent party to this dispute.
    • But that isn’t all; Sudan to is concerned that if Ethiopia were to gain control over the river, it would affect the water levels Sudan receives.

    Why does Ethiopia want this dam?

    • Ethiopia’s goal is to secure electricity for its population and to sustain and develop its growing manufacturing industry.
    • Addis Ababa anticipates that this dam will generate approximately 6,000 megawatts of electricity when it is completed, that can be distributed for the needs of its population and industries.
    • In addition to its domestic requirements, Ethiopia may sell surplus electricity to neighbouring nations like Kenya, Sudan, Eritrea and South Sudan, that also suffer from electricity shortages, to generate some revenue.

    What lies ahead?

    • Despite previous talks, the point of contention hasn’t changed: Egypt and Sudan are concerned about the filling and the operation of the dam.
    • Ethiopia continues to insist that the dam is required to meet the needs of its population and has said that downstream water supplies will not be adversely affected.
    • Cairo insists that the dam would cut its water supplies — concerning for a country that depends on the Nile for approximately 97% of its drinking water and irrigation supplies.
    • Sudan believes that the dam will reduce flooding, but is concerned about the path forward if the negotiations end at a stalemate.

    FSSAI slashes limit for Trans Fats level in food

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Trans fats

    Mains level: Health threats posed by Trans Fats

    The Food Safety and Standards Authority of India (FSSAI) has capped the amount of trans fatty acids (TFA) in oils and fats to 3% for 2021 and 2% by 2022 from the current permissible limit of 5%.

    New FSSAI norms

    • FSSAI has acted in response to the amendment to the Food Safety and Standards (Prohibition and Restriction on Sales) Regulations.
    • The country’s food regulatory body notified the amendment on December 29, more than a year after it issued a draft on the subject for consultation with stakeholders.
    • The revised regulation applies to edible refined oils, vanaspati (partially hydrogenated oils), margarine, bakery shortenings, and other mediums of cooking such as vegetable fat spreads and mixed fat spreads.
    • It was in 2011 that India first passed a regulation that set a TFA limit of 10% in oils and fats, which was further reduced to 5% in 2015.

    What are Trans Fats?

    • Artificial Trans fats are created in an industrial process that adds hydrogen to liquid vegetable oils to make them more solid.
    • Since they are easy to use, inexpensive to produce and last a long time, and give foods a desirable taste and texture, they are still widely used despite their harmful effects being well-known.

    Why such a regulation?

    • Trans fats are associated with increased risk of heart attacks and death from coronary heart disease.
    • As per the WHO, approximately 5.4 lakh deaths take place each year globally because of intake of industrially-produced trans-fatty acids.
    • The WHO has also called for global elimination of trans fats by 2023.

    RBI comes up with Digital Payments Index

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Various parameters of the index

    Mains level: Digital banking in India

    The RBI has constructed a composite Digital Payments Index (DPI) with March 2018 as the base period to capture the extent of digitization of payments across the country.

    Note various indicators of the DPI.

    Digital Payments Index

    • RBI-DPI will be published on the central bank’s website on a semi-annual basis from March 2021 onwards with a lag of four months.
    • It comprises five broad parameters that enable the measurement of deepening and penetration of digital payments in the country over different time periods.
    • The parameters are:
    1. Payment enablers (weight 25 percent)
    2. Payment infrastructure–demand-side factors (10 percent)
    3. Payment infrastructure – supply-side factors (15 percent)
    4. Payment performance (45 percent) and
    5. Consumer centricity (5 percent)
    • Each of these parameters has sub-parameters which, in turn, consist of various measurable indicators, RBI said.

    Why need such an Index?

    • Digital payments in India have been growing rapidly.
    • The DPI reflects accurately the penetration and deepening of various digital payment modes.
  • Telecom and Postal Sector – Spectrum Allocation, Call Drops, Predatory Pricing, etc

    What is Interconnection Usage Charge (IUC) in Telecom?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: IUC

    Mains level: TRAI and its regulations of telecom services

    The termination charge for wireless to wireless domestic calls has been zeroed from January 1 onwards. Until now operators paid Interconnection Usage Charges (IUC) of 6 paise per minute on mobile calls.

    We are heading for 5G and yet we were indulged in 2G era spat. Sounds strange, but finally IUC got away….

    Interconnection Usage Charge (IUC)

    • IUC is the cost that a mobile operator pays to another operator for carrying through/ terminating a call.
    • If a customer of Mobile Operator A calls a customer of Mobile Operator B and the call is completed, then A pays an IUC charge to B for carrying/facilitating the call.
    • Essentially, it is the originating network compensating the receiving network for the cost of carrying the call. In India, IUC is set by the TRAI.

    When was it introduced?

    • IUC was introduced at a time when some operators had a larger network footprint compared to new players.
    • In such a scenario, the larger operators had to be compensated for the investments it had to enable call completion. However, over the years this gap between operators has reduced.
    • All the remaining operators have identical network footprint when it comes to voice calls.
    • TRAI’s original deadline to phase out IUC was January 1, 2020.

    What does it mean to Consumers?

    • For mobile users, this means that all voice calls will be free from now on.
    • While almost all operators had already started offering unlimited calls as part of their bundled pack, some were charging the 6 paise from consumers for paying IUC charges.
    • From January 1, operators will stop collecting the charges.
    • But other than that there will not be any significant gain for users. Tariff packs available in the market already offer data with unlimited voice calls.

    What does the end of the IUC regime imply?

    • For the operators, the end of the IUC regime will lead to easier operations.
    • Many legal battles have been fought in the past over disputes related to IUC charges.
    • Now, the operators can keep whatever money they collect from consumers without having to keep a tab on where the call is terminating.
    • The change in the billing system will not have any significant impact on operators’ revenue.

    What is Operation Meghdoot?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Operation Meghdoot

    Mains level: Not Much

    Colonel Narinder ‘Bull’ Kumar (Retd.), instrumental in the Army launching Operation Meghdoot and securing the dominating heights of Siachen Glacier in 1984 has passed away at 87.

    Operation Meghdoot

    • Operation Meghdoot was the codename for the Indian Armed Forces’ operation to seize control of the Siachen Glacier in Kashmir, precipitating the Siachen conflict.
    • The Siachen then had become a bone of contention following a vague demarcation of territories in the Karachi Agreement of July 1949.
    • Executed in the morning of 13 April 1984, this military operation, launched on the highest battlefield in the world, was the first offensive of its kind.
    • The operation preempted Pakistan’s impending Operation Ababeel and was a success, resulting in Indian forces gaining control of the Siachen Glacier in its entirety.
    • Currently, the Indian Army remains the first and only army in the world to have taken tanks and other heavy ordnance up to such an altitude (well over 5,000 m or 16,000 ft).

    Bull Kumar’s contributions

    • Kumar, a legendary mountaineer who had spotted Pakistani activities around the Siachen glacier in 1984 that helped India secure it subsequently.
    • He was awarded Padma Shri, the fourth highest civilian award, in 1965.
    • He was decorated with Param Vishisht Seva Medal (PVSM), Kirti Chakra, and Ati Vishisht Seva Medal (AVSM).
    • The battalion headquarters on the glacier located close to an altitude of 16,000 feet is named “Kumar post” in his honor.

    Foreign architects of Indian cities

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Indian architecture

    Mains level: Indian architecture and foreign influence

    A controversy has been playing out over the last several days over a decision by the IIM Ahmedabad to bring down 18 dormitories built by legendary American architect Louis Kahn on the old campus.

    This newscard is full of facts. But one must note the features of present-day Indian Architecture and the western influence on it.

    Kahn, in fact, is one among several foreign architects whose work defines several Indian cities. Take a glimpse of all important architects and their works:

    Antonin Raymond & George Nakashima

    • Golconde, one of India’s first modernist buildings, was conceptualized in Puducherry by the founders of the experimental township of Auroville.
    • Tokyo-based Czech architect Antonin Raymond was invited to design this space as a universal commune, and Japanese-American woodworker George Nakashima would complete it after Raymond left India.
    • It is possibly India’s first reinforced concrete buildings, built between 1937 and 1945.
    • Its façade creates the impression that one could open or shut these concrete blinds, without compromising on privacy, while the ascetic interiors helped provide a meditative atmosphere.

    Otto Koenigsberger

    • Berlin-bred Koenigsberger was already working for the Maharaja of Mysore in the late 1930s when he was commissioned by Tata & Sons to develop the industrial township of Jamshedpur in the early 1940s.
    • He would later design the masterplan for Bhubhaneswar (1948) and Faridabad (1949).
    • Having seen children and women walk large distances to reach schools and workplaces, he planned for schools and bazaars in the city center and for a network of neighborhoods.
    • His friends Albert Mayer and Mathew Nowicki would go on to design Chandigarh.
    • However, much before Koenigsberger, there was the Scottish biologist and geographer Patrick Geddes, who wrote town planning reports, from 1915 to 1919, for 18 Indian cities, including Bombay and Indore.

    Frank Lloyd Wright

    • Though the legendary American architect never built a structure in India, his influence was unmistakable.
    • Two of his students, Gautam and Gira Sarabhai, founders of the National Institute of Design, Ahmedabad, requested him to design the administration building for Sarabhai Calico Mills in 1946.
    • It would possibly have been the city’s first high-rise with terraces and a podium.
    • Padma Vibhushan Charles Correa, one of India’s finest architects and urban planners, was hugely influenced by Wright.

    Le Corbusier

    • Before Swiss-French painter-writer-architect Corbusier came on the scene in Chandigarh, there was Polish architect Mathew Nowicki, an admirer of Frank Lloyd Wright and American developer Albert Mayer.
    • Nowicki’s death in a plane crash ended the commission, and Corbusier came on board.
    • With English architect Maxwell Fry and his wife Jane Drew, Corbusier with his cousin Pierre Jeanneret would design many of Chandigarh’s civic buildings, from courts to housing.
    • Corbusier’s modernist approach, without decoration, gave India its brutalist, bare concrete buildings.
    • He won favour with the Sarabhai’s of Ahmedabad and built the Sarabhai House, Shodhan House, Mill Owner’s Association Building and Sankar Kendra. He is often called the “father of modern Indian architecture”.

    Joseph Allen Stein

    • He was invited by Vijayalakshmi Pandit in 1952 to come to India and establish the Department of Architecture and Planning at the West Bengal Engineering College.
    • Though he also practiced briefly in Orissa and West Bengal, it’s in New Delhi where Stein left the deepest imprint.
    • From the Triveni Kala Sangam, the High Commissioner’s Residence and Chancery for Australia, where his polygon-shaped masonry with local stone made its first appearance to ‘Steinabad’.

    Louis Kahn

    • The importance of being Kahn is never more real than now, as the American architect’s only project in India faces bulldozers.
    • The design for IIM Ahmedabad (1962-1974) carried the essence of learning in the humility of its material, and the way spaces were managed.
