    (d) None

    Ramagundam Solar Plant

    • It would be one of the renewable (solar) energy plants being developed by NTPC with an installed capacity of 447MW in the Southern Region and the entire capacity would be commissioned by March 2023.
    • It will be spread over 450 acres of water surface area in the reservoir.
    • It will be the single location largest floating solar plant in the country as of now; 92 MW floating unit at Kayamkulam gas plant in Kerala and a 25 MW unit at Simhadri power plant.
    • In addition, we are setting up a 230 MW ground-mounted solar power plant in Ettayapuram near Tuticorin in Tamil Nadu

    Why floating solar?

    • One of the biggest advantages of floating solar panels is that the installations do not require valuable land space.
    • Many of these installations can take up unused space on bodies of water, such as hydroelectric dam reservoirs, wastewater treatment ponds, or drinking water reservoirs.
    • Additionally, installing solar panels out on open water reduces the need for tree removal and forest clearing, a practice used in the case of some larger solar panel installations.
    • The bodies of water that host floating solar arrays help cool down the solar equipment, which means the panels produce electricity at higher efficiencies in hot climates than they might otherwise.
    • The floating solar panel structure shades the body of water and reduces evaporation from these ponds, reservoirs, and lakes.
    • This is a particularly useful benefit in areas susceptible to drought, as water loss to evaporation can add up over time and contribute to a shortage.

    Back2Basics: UNESCO World Heritage Sites

    • A World Heritage Site is a landmark or area, selected by the UN Educational, Scientific and Cultural Organization (UNESCO) for having cultural, historical, scientific or other forms of significance, which is legally protected by international treaties.
    • The sites are judged to be important for the collective and preservative interests of humanity.
    • To be selected, a WHS must be an already-classified landmark, unique in some respect as a geographically and historically identifiable place having special cultural or physical significance (such as an ancient ruin or historical structure, building, city, complex, desert, forest, island, lake, monument, mountain, or wilderness area).
    • It may signify a remarkable accomplishment of humanity, and serve as evidence of our intellectual history on the planet.
    • The sites are intended for practical conservation for posterity, which otherwise would be subject to risk from human or animal trespassing, unmonitored/uncontrolled/unrestricted access, or threat from local administrative negligence.
    • The list is maintained by the international World Heritage Program administered by the UNESCO World Heritage Committee, composed of 21 “states parties” that are elected by their General Assembly.

    UNESCO World Heritage Committee

    • The World Heritage Committee selects the sites to be listed as UNESCO World Heritage Sites, including the World Heritage List and the List of World Heritage in Danger.
    • It monitors the state of conservation of the World Heritage properties, defines the use of the World Heritage Fund and allocates financial assistance upon requests from States Parties.
    • It is composed of 21 states parties that are elected by the General Assembly of States Parties for a four-year term.
    • India is NOT a member of this Committee.

  • Forest fire in Simlipal Biosphere Reserve

    The Simlipal forest reserve area frequently witnesses forest fires during dry weather conditions.

    Try this PYQ:

    Q.From the ecological point of view, which one of the following assumes importance in being a good link between the Eastern Ghats and the Western Ghats?

    (a) Sathyamangalam Tiger Reserve

    (b) Nallamala Forest

    (c) Nagarhole National Park

    (d) Seshachalam Biosphere Reserve

    Simlipal Biosphere Reserve

    • Similipal, which derives its name from the ‘Simul’ (silk cotton) tree, is a national park and a tiger reserve situated in the northern part of Odisha’s Mayurbhanj district.
    • Similipal and the adjoining areas, comprising 5,569 sq km, was declared a biosphere reserve by the Government of India on June 22, 1994, and lies in the eastern end of the eastern ghat.
    • It includes three protected areas — Similipal Tiger Reserve, Hadgarh Wildlife Sanctuary with 191.06 km2 (73.77 sq mi) and Kuldiha Wildlife Sanctuary.
    • It is the abode of 94 species of orchids and about 3,000 species of plants.
    • The identified species of fauna include 12 species of amphibians, 29 species of reptiles, 264 species of birds and 42 species of mammals, all of which collectively highlight the biodiversity richness of Similipal.
    • Sal is a dominant tree species.

    How fire-prone is Simlipal forest?

    • Generally, with the onset of summers and towards the end of autumn, the forest area remains vulnerable to forest fires.
    • They are a recurrent annual phenomenon but are also brought under control due to the short span of precipitation.
    • This duration coincides with the shedding of deciduous forests in the forest areas.
    • The fallen leaves are more vulnerable to catching fire and facilitate the spreading of these forest fires quickly over the entire forest area.

  • Places in news: Mount Sinabung

    Indonesia’s Mount Sinabung volcano sent a cloud of hot ash as high as 3 km today, in its first big eruption since August last year.

    Mount Sinabung

    • It is a Pleistocene-to-Holocene stratovolcano in the Karo plateau of Karo Regency, North Sumatra, Indonesia.
    • It is created by the subduction of the Indo-Australian Plate under the Eurasian Plate.
    • It erupted in 2010 after a 400-year-long hiatus and has been continuously active since September 2013.

    Why frequent eruptions?

    • Indonesia straddles the “Pacific ring of fire” with nearly130 active volcanoes, more than any other country.

    Lake Chad

    • Lake Chad in the Sahel spans the countries of Nigeria, Niger, Chad and Cameroon and is home to 17.4 million people.
    • It is blessed with rich aquatic and terrestrial biodiversity.
    • The Chari River, fed by its tributary the Logone, provides over 90% of the lake’s water, with a small amount coming from the Yobe River in Nigeria/Niger.
    • Despite high levels of evaporation, the lake is freshwater.
    • The Lake Chad basin comprises biosphere reserves, World Heritage and Ramsar sites as well as wetlands of international conservation importance.

    Why it is significant?

    • For years, the lake has been supporting drinking water, irrigation, fishing, livestock and economic activity for over 30 million people in the region.
    • It is vital for indigenous, pastoral and farming communities in one of the world’s poorest countries.
    • However, climate change has fuelled a massive environmental and humanitarian crisis.
    • The United Nations has termed the Lake Chad crisis as “one of the worst in the world”.

    A looming peril

    • The lake has shrunk 90 per cent over the last 60 years since the chronic droughts surged at the beginning of the 1970s.
    • The surface area of the lake was 26,000 square kilometres in 1963; it has now reduced to less than 1,500 square kilometres.
    • Its population is exploding and the region has been ripped apart from conflict at an unprecedented scale.

    Behind all crises

    • The ever-changing climate has dramatically worsened the situation, amplifying food and nutritional insecurity in the region.
    • Temperature is rising one-and-a-half times faster than the global average. The seasonal and inter-rainfall patterns have been drastically changing each year.
    • This has triggered food insecurity, ultimately pushing communities into the arms of terrorist groups.
    • Boko Haram is one of the top insurgent groups with a strong foothold in the region.

  • Mawsynram: Wettest place on Earth sees a decreasing trend in rainfall

    A recent study that looked at the rainfall pattern in the past 119 years found a decreasing trend at Cherrapunji and nearby areas.

    Try this PYQ:

    Q.“Climate is extreme, rainfall is scanty and the people used to be nomadic herders.” The above statement best describes which of the following regions?

    (a) African Savannah

    (b) Central Asian Steppe

    (c) North American Prairie

    (d) Siberian Tundra

    Mawsynram

    • Mawsynram is a town in the East Khasi Hills district of Meghalaya state in northeastern India, 60.9 kilometres from Shillong.
    • Mawsynram receives the highest rainfall in India.
    • It is reportedly the wettest place on Earth, with an average annual rainfall of 11,872mm but that claim is disputed.
    • According to the Guinness Book of World Records, Mawsynram received 26,000 millimetres (1,000 in) of rainfall in 1985.

    Why it rain highest in Mawsynram?

    • Because of the uneven relief of India due to the presence of a number of hill ranges, the monsoon is not able to shed its moisture evenly over India.
    • Windward sides receive more rainfall and leeward sides receive less rainfall.
    • Mawsynram lies in the funnel-shaped depression caused by the Khasi range in Meghalaya.
    • The Bay of Bengal branch of monsoons is trapped in it and causes heavy rainfall.

    Decreasing rainfall trends

    • The research analysed daily rain gauge measurements during 1901–2019 and noted that the changes in the Indian Ocean temperature have a huge effect on the rainfall in the region.
    • There was a reduction in the vegetation area in northeast India in the past two decades, implying that human influence also plays an important role in the changing rainfall patterns.
    • The traditional way of cultivation known as Jhum cultivation or shifting cultivation is now decreased and being replaced by other methods.
    • Also, previous studies have noted there is sizable deforestation in the region.

  • Species in news: Mandarin Duck

    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

    • The Maguri Motapung wetland is an Important Bird Area as declared by the Bombay Natural History Society.
    • It is located close to the Dibru Saikhowa National Park in Upper Assam.
    • The entire ecosystem is very important as it is home to at least 304 bird species, including a number of endemic ones like Black-breasted parrotbill and Marsh babbler.
    • In May 2020, the beel was adversely affected by a blowout and fire at an Oil India Limited-owned gas well.

  • Farakka ‘lock’ and Hilsa Fish

    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.

    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.

    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.
