  • Places in news: Lemru Elephant Reserve

    The proposed Lemru Elephant Reserve in Chhattisgarh, in the pipeline for 20 years, has become the subject of yet another controversy over the reduction of its size.

    Lemru Elephant Reserve

    • The proposal for the reserve, in Korba district, was passed unanimously by the Assembly in 2005 and got central approval in 2007.
    • Lemru is one of two elephant reserves planned to prevent human-animal conflict in the region, with elephants moving into Chhattisgarh from Odisha and Jharkhand.
    • Its area was then proposed to be 450 sq km.

    Why does the government want to reduce the size of the reserve?

    • The area proposed under the reserve is part of the Hasdeo Aranya forests, a very diverse biozone that is also rich in coal deposits.
    • Of 22 coal blocks in the area, seven have already been allotted with mines running in three, and in the process of being established in the other four.
    • Under the ‘No-Go Area’ policy from the UPA area, the entire area was considered out of bounds for mines, but in 2020, five coal blocks from the region were put on the auction list.

    Why is the reserve important?

    • North Chhattisgarh alone is home to over 240 elephants.
    • Elephants in Chhattisgarh are relatively new; they started moving into undivided Madhya Pradesh in 1990.
    • Since these animals were relatively new, the human-animal conflict started once elephants started straying into inhabited areas, looking for food.

  • Places in news: Black Sea

    Russia accused Britain of spreading lies over a warship confrontation in the Black Sea.

    What is the issue?

    • Russia annexed Ukraine’s Crimean Peninsula in 2014, a move that was not recognized by most countries in the world.
    • Russia has frequently responded at NATO warships visits near Crimea, casting them as destabilizing.
    • NATO members Turkey, Greece, Romania and Bulgaria are in the Black Sea, but warships from the US, UK and other NATO allies also have made increasingly frequent visits in a show of support to Ukraine.

    About Black Sea

    • The Black Sea is a marginal sea of the Atlantic Ocean lying between Europe and Asia; east of the Balkans (Southeast Europe), south of the East European Plain in Eastern Europe, west of the Caucasus, and north of Anatolia in Western Asia.
    • It is supplied by major rivers, principally the Danube, Dnieper, and Don.
    • The watersheds of many countries drain into the sea beyond the six that share its coast.
    • The Black Sea is bordered by Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine.

  • Places in news: Yellowstone National Park

    A new assessment of climate change in the Yellowstone National Park shows that it has lost a quarter of its annual snowfall.

    Yellowstone National Park

    • Yellowstone NP is an American national park located in the western United States, largely in the northwest corner of Wyoming and extending into Montana and Idaho.
    • Yellowstone was the first national park in the US and is also widely held to be the first national park in the world.
    • The park is known for its wildlife and its many geothermal features, especially Old Faithful geyser, one of its most popular.
    • While it represents many types of biomes, the subalpine forest is the most abundant. It is part of the South Central Rockies forests ecoregion.
    • The area also represents the one point where the three major river basins of the western U.S. converge.
    • The rivers of the Snake-Columbia basin, Green-Colorado basin, and Missouri River Basin all begin as snow on the Continental Divide as it weaves across Yellowstone’s peaks and plateaus.

    Impact of climate change

    • Since 1950, average temperatures in the Greater Yellowstone Area have risen 1.3°C and potentially, more importantly, the region has lost a quarter of its annual snowfall.
    • The loss of snow there has repercussions for a vast range of ecosystems and wildlife, as well as cities and farms downstream that rely on rivers that start in these mountains.
    • It is home to the southernmost range of grizzly bear populations in North America and some of the longest intact wildlife migrations, including the seasonal traverses of elk, pronghorn, mule deer and bison.

  • NatGeo recognizes ‘Southern Ocean’ as globe’s fifth ocean

    The National Geographic magazine has recognized the ‘Southern Ocean’ as the world’s fifth ocean June 8, 2021 hoping others will soon follow suit.

    Answer this PYQ from CSP 2019 in the comment box:

    Q.The most important fishing grounds of the world are found in the regions where:

    (a) warm and cold atmospheric currents meet

    (b) rivers drain out large amounts of freshwater into the sea

    (c) warm and cold oceanic currents meet

    (d) continental shelf is undulating

    Southern Ocean

    • The Southern Ocean, also known as the Antarctic Ocean, comprises the southernmost waters of the World Ocean, generally taken to be south of 60° S latitude and encircling Antarctica.
    • As such, it is regarded as the second-smallest of the five principal oceanic divisions: smaller than the Pacific, Atlantic, and Indian oceans but larger than the Arctic Ocean.
    • Over the past 30 years, the Southern Ocean has been subject to rapid climate change, which has led to changes in the marine ecosystem.

    What has NatGeo attempted?

    • The magazine says the Southern Ocean is the only ocean ‘to touch three other oceans and to completely embrace a continent rather than being embraced by them’.
    • Its northern limit is a latitude of 60 degrees south.
    • It is also defined by its Antarctic Circumpolar Current that was formed 34 million years ago. The current flows from west to east around Antarctica.
    • The Southern Ocean is home to large populations of whales, penguins, and seals.

    Why such a move?

    • Usually, the magazine has followed the International Hydrographic Organization (IHO) on marine names, it said in an article notifying the change.
    • The IHO too had recognized ‘Southern Ocean’ as a distinct body of water surrounding Antarctica in 1937 but had repealed the same in 1953.

  • Places in news: Sardar Sarovar Dam

    The Sardar Sarovar Dam is providing irrigation water in summer for the first time in history.

    Sardar Sarovar Dam

    • The Sardar Sarovar Narmada Dam is a terminal dam built on the Narmada river at Kevadia in Gujarat’s Narmada district.
    • Four Indian states, Gujarat, Madhya Pradesh, Maharashtra and Rajasthan, receive water and electricity supply from the dam.
    • The foundation stone of the project was laid out by Prime Minister Jawaharlal Nehru on 5 April 1961.
    • The project took form in 1979 as part of a development scheme funded by the World Bank through their International Bank for Reconstruction and Development, to increase irrigation and produce hydroelectricity
    • Called the ‘lifeline of Gujarat’, it usually has no water for irrigation during summers.

    Q.Which one of the following pairs is not correctly matched?

     

    Dam/Lake River

    (a) Govind Sagar: Satluj

    (b) Kolleru Lake: Krishna

    (c) Ukai Reservoir: Tapi

    (d) Wular Lake: Jhelum

    A successful model of river water sharing

    • River Narmada is a classic case of Integrated River Basin Planning, Development, and Management, with water storage available in all major, medium, and minor dams on the main river and its tributaries.
    • Its water is shared amongst four party states – Gujarat, Rajasthan, Madhya Pradesh and Maharashtra — in the ratio stipulated by the 1979 award of the Narmada Water Dispute Tribunal.

    How has it saved water for summers?

    • During the monsoon from July to October, the reservoir operation is well synchronized with the rain forecast in the catchment area.
    • The strategic operation of River Bed Power House (RPBH) ensures that minimum water flows downstream into the sea and maximum water is used during the dam overflow period, which is not calculated in the annual water share.
    • These measures help in maximizing the annual allocation of water share.
    • Similarly, in non-monsoon months, the measures for efficient use of the allocated share typically include minimizing the conventional and operational losses.
    • It includes: avoiding water wastage, restricting water-intensive perennial crops, adopting of Underground Pipelines (UGPL); proper maintenance and operation of canals on a rotational basis.

  • Dihing Patkai is Assam’s 7th National Park

    The Assam government has notified Dihing Patkai as a National Park, four days after creating the 422-sq. km Raimona National Park in western Assam’s Kokrajhar district.

    Dihing Patkai NP

    • Dihing Patkai, in focus a year ago for illegal coal mining in the vicinity, encompasses the erstwhile Dehing Patkai Wildlife Sanctuary, the Jeypore Reserve Forest and the western block of the Upper Dihing Reserve Forest.
    • The 234.26-sq. km Dihing Patkai straddling eastern Assam’s Dibrugarh and Tinsukia districts is a major elephant habitat and 310 species of butterflies have been recorded there.

    • Kaziranga and Manas are UNESCO World Heritage Sites.
    • They are also tiger reserves along with Nameri and Orang.

  • Degradation of Aravalis

    The Supreme Court has ordered the Haryana government to take “all essential measures” to remove encroachments, including some residential constructions, in the ecologically fragile Aravali forest land near a village.

    Aravali Range

    • The Aravali is a mountain range in Northwestern India, running approximately 670 km in a southwest direction, starting near Delhi, passing through southern Haryana and Rajasthan, and ending in Gujarat.
    • The highest peak is Guru Shikhar at 1,722 meters.
    • The Aravalli Range, an eroded stub of ancient mountains, is the oldest range of fold mountains in India.
    • The natural history of the Aravalli Range dates back to times when the Indian Plate was separated from the Eurasian Plate by an ocean.
    • Three major rivers and their tributaries flow from the Aravalli, namely Banas and Sahibi rivers which are tributaries of Yamuna, as well as Luni River which flows into the Rann of Kutch.
    • The Sariska-Delhi leopard wildlife corridor is a 200 km long important biodiversity and wildlife corridor which runs from the Sariska Tiger Reserve in Rajasthan to Delhi Ridge.

    Threats to its existence

    • Ecological degradation in the Aravalli region is in an alarming situation.
    • This is due to the increasing population of humans and cattle, injudicious use of natural resources, unscientific mining, uncontrolled grazing, and felling of trees.

  • Kinnaur Hydroelectric Project

    The people of Kinnaur, Himachal Pradesh have been protesting against the proposed 804-megawatt Jangi Thopan Powari hydroelectricity project (JTP HEP) over the Satluj since April 2021.

    Kinnaur Hydroelectric Project

    • The run-of-the-river (ROR) project envisages the construction of a concrete gravity dam of ±88 metres high above the deepest foundation level across river Satluj near Jangi village.
    • The diversion of water will involve the construction of a 12-km-long tunnel.
    • The tentative land requirement for the project is 295.93 hectares, out of which 270.43 ha is forest land and 25.5 ha is private.
    • Construction of the dam will result in the submergence of about 156.2917 ha of land, out of which 143.2093 ha is forest land and 13.0824 ha is private.

    Q.What is common to the places known as Aliyar, Isapur and Kangsabati? (CSP 2017)

    (a) Recently discovered uranium deposits

    (b) Tropical rain forests

    (c) Underground cave systems

    (d) Water reservoirs

    Why are people protesting?

    • Kinnaur district is mainly marked by its cold desert, tribal population, fragile topography, rich and diverse culture, apple orchards, off-season vegetables and the Satluj river.
    • The river has been dammed at multiple places along the valley to create an additional feature to Kinnaur’s identity as Himachal’s hydropower hub, which locals believe is a malediction.
    • An integral part of the old Hindustan-Tibetan Route, Jangram Valley, lies on the right bank of the Satluj river in the district.
    • This is not the first time that the cold desert has witnessed such a contestation.

    Sutlej is oveloaded

    • The Satluj has taken the biggest load of state hydropower ambition since the early 90s. Out of the total installed capacity, 56 per cent (5720MW) is done in the Satluj basin.
    • According to the State of the Rivers of Himachal Pradesh Report 2017:
    • In other words, 92 per cent of the river will either be flowing through tunnels or will be part of reservoirs.
    • Such a cumulative scale of disturbance with the river’s natural state drastically impacted the life, livelihood and ecology in the Satluj basin.

    Why need hydroelectric projects?

    • Hydropower is a necessary choice for the nation’s clean energy transition.
    • In purely technological terms, hydropower projects are an engineering marvel and generate clean, reliable electricity.
    • HEPs are not viable just from the local livelihood and environmental point of view but they have also failed on the financial viability side.

  • ‘Sea Snot’ outbreak in Turkey

    There has been growing environmental concern in Turkey over the accumulation of ‘sea snot’, a slimy layer of grey or green sludge in the country’s seas, which can cause considerable damage to the marine ecosystem.

    What is ‘Sea Snot’?

    • ‘Sea snot’ is marine mucilage that is formed when algae are overloaded with nutrients as a result of water pollution combined with the effects of climate change.
    • A ‘sea snot’ outbreak was first recorded in the country in 2007. Back then, it was also spotted in the Aegean Sea near Greece.
    • But the current outbreak in the Sea of Marmara is by far the biggest in the country’s history.
    • The nutrient overload occurs when algae feast on warm weather caused by global warming. Water pollution adds to the problem.
    • Environmental experts have said that the overproduction of phytoplankton caused by climate change and the uncontrolled dumping of household and industrial waste into the seas has led to the present crisis.

    Where has it been found?

    • Turkey’s Sea of Marmara, which connects the Black Sea to the Aegean Sea, has witnessed the largest outbreak of ‘sea snot’.
    • The sludge has also been spotted in the adjoining Black and Aegean seas.

    How badly can the crisis affect the marine ecosystem?

    • The growth of the mucilage, which floats upon the surface of the sea like brown phlegm, is posing a severe threat to the marine ecosystem of the country.
    • Divers have said that it has caused mass deaths among the fish population, and also killed other aquatic organisms such as corals and sponges.
    • The mucilage is now covering the surface of the sea and has also spread to 80-100 feet below the surface.
    • If unchecked, this can collapse to the bottom and cover the sea floor, causing major damage to the marine ecosystem.
    • Over a period of time, it could end up poisoning all aquatic life, including fishes, crabs, oysters, mussels and sea stars.

  • Places in news: Pandav Leni Complex

    The Archaeological Survey of India (ASI) has found three more caves in the Trirashmi Buddhist cave complex, also known as Pandav Leni, near Nashik, Maharashtra.

    Answer this PYQ first, in the comment box:

    Q.There are only two known examples of cave paintings of the Gupta period in ancient India. One of these is paintings of Ajanta caves. Where is the other surviving example of Gupta paintings?

    (a) Bagh caves

    (b) Ellora caves

    (c) Lomas Rishi cave

    (d) Nasik caves

    Pandav Leni Complex

    • The Pandav Leni Complex or Nasik Caves are a group of 23 caves carved between the 1st century BCE and the 3rd century CE.
    • Also called Trirashmi Buddhist caves, this complex was first documented in 1823 by Captain James Delamaine and is now an ASI- protected site.
    • Though additional sculptures were added up to about the 6th century, it is a major landmark of changes in Buddhist devotional practices.
    • Most of the caves are viharas except for Cave 18 which is a chaitya of the 1st century BCE.
    • The style of some of the elaborate pillars or columns, for example in caves 3 and 10, is an important example of the development of the form.
    • The “Pandavleni” name sometimes given to the Nasik Caves has nothing to do with the characters Pandavas, characters in the Mahabharata epic.
    • Other caves in the area are Karla Caves, Bhaja Caves, Patan Cave, and Bedse Caves.
