    Degradation of Aravalis

    India Mapping | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Aravali Range and its geophysics

    Mains level: NA

    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

    India Mapping | Economics | Mains Paper 3: Infrastructure: Energy, Ports, Roads, Airports, Railways Etc.

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Kinnaur Hydroelectric Project

    Mains level: Hydel energy and its feasiblity

    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.

    Answer this PYQ in the comment box:

    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

    India MappingPrelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Sea Snot, Marmara Sea

    Mains level: Algal bloom

    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.

    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.

    A huge ice block has broken off from western Antarctica into the Weddell Sea, becoming the largest iceberg in the world and earning the name A-76.

    Answer this PYQ in the comment box:

    Q.On the planet earth, most of the freshwater exists as ice caps and glaciers. Out of the remaining freshwater, the largest proportion:

    (a) is found in the atmosphere as moisture and clouds

    (b) is found in freshwater lakes and rivers

    (c) exists as groundwater

    (d) exists as soil moisture

    A-76 Iceberg

    • A-76 is the latest in a series of large ice blocks to dislodge in a region acutely vulnerable to climate change, although scientists said in this case it appeared to be part of a natural polar cycle.
    • The iceberg, measuring around 170 km long and 25 km wide, with an area of 4,320 sq km is now floating in the Weddell Sea.
    • Slightly larger than the Spanish island of Majorca, A-76 had been monitored by scientists since it began to separate from the Ronne Ice Shelf.
    • It joins the previous world’s largest title holder A-23A — approximately 3,880 sq. km. in size — which has remained in the same area since 1986.
    • A-76 was originally spotted by the British Antarctic Survey and the calving — the term used when an iceberg breaks off — was confirmed using images from the Copernicus satellite.

    Note: An iceberg is a large piece of freshwater ice that has broken off a glacier or an ice shelf and is floating freely in open water.

    Prelims level: Leang Sakapao Caves

    Mains level: Not Much

    Researchers have reported that Pleistocene-era rock paintings dating back to 45,000-20,000 years ago in cave sites in southern Sulawesi, on the Indonesian island of Sulawesi, are weathering at an alarming rate.

    Have you ever found the mention of ‘Altamira Caves’ in your NCERTs?

    Leang Sakapao Caves

    • This cave art of Sulawesi is much older than the prehistoric cave art of Europe.
    • The artwork in the area includes what is believed to be the world’s oldest hand stencil (almost 40,000 years ago), created by pressing the hand on a cave wall and spraying wet red-mulberry pigments over it.
    • A nearby cave features the world’s oldest depiction of an animal, a warty pig painted on the wall 45,500 years ago.

    Impact of climate change

    • The artwork made with pigments was decaying due to a process known as haloclasty, which is triggered by the growth of salt crystals due to repeated changes in temperature and humidity.
    • This is caused by alternating wet and dry weather in the region.
    • Indonesia has also experienced several natural disasters in recent years, which have quickened the process of deterioration.

    From UPSC perspective, the following things are important:

    Prelims level: Farzad B Gas Field

    Mains level: Not Much

    Iran gave the Farzad B gas field to a domestic gas producer in a setback move to India.

    Farzad B Gas Field

    • Farzad-B is an off-shore natural gas field 20 kilometres off Farsi Island in Iran.
    • The gas field was discovered in 2008 by a consortium of three Indian companies, led by the state-owned ONGC Videsh with a 40% stake; the other companies were Indian Oil Corporation (40%) and Oil India (20%).

    Deal soured after US sanctions

    • Negotiations between the consortium and the National Iranian Oil Company (NIOC) to develop the gas field stalled due to secondary sanctions against Iran by the US and the European Union in the early 2010s.
    • Following the lifting of sanctions after the Joint Comprehensive Plan of Action was signed in July 2015 the consortium was close to an agreement to invest $US5 billion to develop the gas field.
    • After the United States withdrawal from the JCPOA in May 2018, and the reinstatement of U.S. sanctions against Iran, the negotiations between the consortium and NIOC broke down.

    Consider the question “Balancing the contrasts has been the basis of India’s relations with Iran. Comment.”
