Enhancing Erosion in the Himalayas

Part of: GS-I- Geography (PT-MAINS-PERSONALITY TEST)

Scientists and students from the Wadia Institute of Himalayan Geology (WIHG) have explored the Zanskar catchment area. The study was conducted to understand the landform evolution in transitional climatic zones, using morphostratigraphy, Optically Stimulated Luminescence (OSL) dating and provenance analysis of landforms like valley fill terraces and alluvial fans.

Valley Fill Terrace: The fill terrace is created by either a stream or river that starts to incise into the material that it deposited in the valley. Once this occurs benches composed completely of alluvium form on the sides of the valley. The uppermost benches are the fill terraces.

Alluvial Fans: Triangle-shaped deposits of gravel, sand and even smaller pieces of sediment, such as silt.

Note: WHIG is an autonomous institute under the Department of Science & Technology, Government of India.

Morphostratigraphy: The organization of rock or sediment strata into units based on their surface morphology (landforms).

Optically-Stimulated Luminescence: It is a late Quaternary dating technique used to date the last time a quartz sediment was exposed to light. As sediment is transported by wind, water or ice, it is exposed to sunlight and zeroed of any previous luminescence signal.

Provenance Analysis: It aims to determine the source region (provenance) of a sediment sample. It is aimed to reconstruct the parent rock or rocks of sand bodies, the time of deposition of the sand and, if possible, the climate conditions during the formation of the sediments.

Key Findings

• Scientists traced where the rivers draining Himalayas and its foreland erode the most and identified the zones which receive these eroded sediments and fill up.
• The study suggested that the wide valley of Padam in the upper Zanskar is a hotspot of sediment buffering and has stored a vast amount of sediments. The sediment contribution from such transient basins is significant when compared to the sediment reportedly eroded from the entire Indus system in Ladakh.
• Most of the sediments in the Padam valley were derived from Higher Himalayan crystalline that lie in the headwater region of Zanskar.
• The dominant factors responsible for sediment erosion were deglaciation and Indian Summer Monsoon derived precipitation in the headwaters.
• The provenance analysis suggested that despite the presence of the deep narrow gorge and a low gradient, the upper and lower Zanskar valleys remained connected throughout their aggradational history.

Significance

• The study will help to understand river-borne erosion and sedimentation, which are the main drivers that make large riverine plains, terraces and deltas that eventually become the evolving grounds for civilizations.
• The study brought forwards the 35 thousand-year history of river erosion and identified hotspots of erosion and wide valleys that act as buffer zones.
• It showed how rivers in drier Ladakh Himalaya operated on longer time scales and how they responded to varying climates. The Ladakh Himalaya forms a high altitude desert between Greater Himalayan ranges and Karakoram Ranges and the Indus and its tributaries are major rivers flowing through the terrain.
• Understanding of water and sediment routing becomes crucial while developing infrastructure and for other development works in the river catchment area.

Earth’s Magnetosphere

Part of: GS-I- Geography (PT-MAINS-PERSONALITY TEST)

Scientists at the Indian Institute of Geomagnetism (IIG) have developed a generalized one-dimensional fluid simulation code capable of studying a wide spectrum of coherent electric field structures in near-earth plasma environments or earth’s magnetosphere.

• The developed simulation code is expected to help in planning of future space missions.

Key Points

• Formation of Earth’s Magnetosphere:
  • Sun is the major source of plasma deposition in space around the Earth. Thus, the Sun forces some of its plasma towards the earth in the form of the solar wind.
    
    • Plasma is the most common state of matter in the universe as a whole.It consists of a gas of ions and free electrons.
  • The speed of solar wind varies between 300 to 1500 km/s, which carries with it a solar magnetic field, called the Interplanetary Magnetic Field (IMF).
  • The interaction of the IMF with the earth’s magnetic field creates the magnetosphere of the earth.
  • The magnetosphere shields our home planet from solar and cosmic particle radiation, as well as erosion of the atmosphere by the solar wind - the constant flow of charged particles streaming off the sun.

Regions of the Earth’s Magnetosphere:

The schematic diagram of Earth’s magnetosphere shown consists of different regions namely,

• • • Bow shock : It occurs when the magnetosphere of an Earth interacts with the nearby flowing ambient plasma such as the solar wind.
    • Magnetosheath: It is the region of space between the magnetopause and the bow shock of a planet's magnetosphere.
    • Magnetopause : It is the boundary between the planet's magnetic field and the solar wind.
    • Northern tail lobe : The magnetosphere of the earth contains two lobes, referred to as the northern and southern tail lobes. Magnetic field lines in the northern tail lobe point towards the earth.
    • Southern tail lobe: The magnetic field lines in the southern tail lobes point away from the earth. Usually, the tail lobes are almost empty, with few charged particles opposing the flow of the solar wind.
    • Plasmasphere : The plasmasphere, or inner magnetosphere, is a region of the Earth's magnetosphere consisting of low energy (cool) plasma.
    • Solar winds: It is a stream of charged particles released from the upper atmosphere of the Sun, called the corona.

Significance of Study of Plasma Processes:

The plasma processes have the ability to hamper the working of a number of satellites that have been placed in orbit in the magnetospheric region. However, the morphology of these plasma processes changes over space and time. These changes can be ideally deciphered only through computer simulations.

The study will help advance the knowledge of plasma waves, instabilities, and coherent effects associated with wave-particle interactions that are useful in planning future space missions. It can also lead to precisely controlled fusion laboratory experiments for ever-expanding energy needs of humanity.

Bois Locker Room

Context

The Delhi police Cyber Cell has registered an FIR after following a complaint about an online Instagram group, police have also apprehended a 15 year old boy from South Delhi for his alleged involvement in a viral Instagram group named ‘Bois Locker Room’, where a bunch of school going boys objectified young girls and discussed their body parts.

Cases registered

After we came to know, we registered an FIR under Sections 465 (forgery), 471 (using as genuine a forged document or electronic record), 469 (forgery for purpose of harming reputation), 509 (word, gesture or act intended to insult the modesty of a woman) and Sections 67 (publishing or transmitting obscene material in electronic form) and 67A (publishing or transmitting of material containing sexually explicit act in electronic form) of the IT Act.

Facebook’s response

Facebook, Instagram’s parent company, also responded to the matter and said, “We absolutely do not allow behaviour that promotes sexual violence or exploits anyone, especially women and young people, and have actioned content violating our Community Standards as we were made aware of it. We have policies that disallow the sharing of non-consensual intimate imagery, as well as threats to share such imagery and we take this issue very seriously. Ensuring our community can express themselves in a safe and respectful way is our top priority.”

Land management body

Part of: GS-III- Economy-Land (PT-MAINS-PERSONALITY TEST)

The task force noted there is a need for a separate organisation, which can work with various government departments including Railways and Defence Ministry to utilise their surplus land assets.

Context

A government panel on boosting infrastructure investment has recommended setting up a National Land Management Corporation, which would help in monetising state-owned surplus land assets in a systematic and specialised way.

Imp Points

• Such a corporation should be set up under the Companies Act to function as the facilitator for land monetisation and an asset manager for lands owned by the government of India and Central Public Sector Enterprises.
• It has been recommended that a chief executive officer (CEO) and a technical team be hired at market-linked compensation to carry out land monetisation.
• The Corporation can raise capital from the equity market, based on the value of its leased assets, just like it has been done recently by some private-owned Real Estate Investment Trusts (REITs), which were listed on the stock exchanges last year.
• The task force noted there is a need for a separate organisation, which can work with various government departments including Railways and Defence Ministry to utilise their surplus land assets.
• After setting up the proposed Corporation, which will identify and manage surplus land assets, concessioning of the land should be done through this special purpose vehicle that would provide land on a lease basis or other revenue sharing modes (including the sale of land) for commercial purposes.
• The panel recommended the Corporation consider the development or co-development of land belonging to defence or railways as well.
• It can also take up co-development of private land parcels adjoining government lands to maximise revenue.

EXPLAINED

Will help in raising funds from market

• The government has been trying to monetise surplus land assets with departments and state-owned companies for the last couple of years.
• Despite large tracts of commercial viable land being available, there has been limited progress on this front.
• The National Land Management Corporation, with a professional team from the market, is being proposed to speed up progress in this area.
• A pipeline of income-yielding properties can be created by such a corporation, which can, in turn, raise funds from the market.

Working module

• Apart from a CEO and technical team, it has been proposed that the Corporation have representation from senior officials of the Finance Ministry, Department of Public Enterprises, Ministry of Housing and Urban Affairs as well as independent directors from finance and real estate industry.
• Besides maintaining an inventory of public land, the Corporation will develop model concession agreements for land development and sale, legal management of litigation/encumbrances relating to land, development planning, design and bid process management.
• Operational requirements like a change of land usage and revenue management functions will also be entrusted with the Corporation.

Along with monetisation of land assets, the task force on National Infrastructure Pipeline, in its report submitted to the government last week, also suggested measures including strengthening of the municipal bond market, deepening of corporate bond markets, and setting up Development Financial Institutions for the infrastructure sector. The task force pegged the total expected capital expenditure for the infra sector at Rs 111 lakh crore in the next five years.

Having income earning inventory of assets would enable the Corporation to raise equity capital or debt from the markets. These funds can be deployed for the development of surplus land assets, creating a pipeline of developable assets. The Corporation may adopt different models for land monetisation, including securitising a pool of assets through structures like REITs and InvITs. Successful bidders in projects could either make a large upfront payments for the assets combined with annual payments or small or zero upfront payments with annual payments.

Part of: GS-III- S&T (PT-MAINS-PERSONALITY TEST)

Corona-Killer 100 is an automated disinfecting Unmanned Aerial Vehicle (UAV) developed by Garuda Aerospace - an ISO- 9001 company.

• These drones will aid in the sanitation of public places, hospitals and tall buildings up to 450 feet amid Covid-19 outbreak.
• It is equipped with fuel efficient motors that enable the drone to be deployed for 12 hours a day.
• Drone operations are faster, longer & safer than manual spraying by workers who can become potential carriers of Covid-19.
• It also consists of patented autopilot technology, advanced flight controller systems.

Drone as a Service

• Historically, many UAV applications were developed in the military as spy or reconnaissance vehicles used during wartime.
• However, the development of this type of aircraft has evolved towards commercial, civil and consumer spaces, including professional videography, surveying, construction, inspection, traffic management and last mile delivery.
• Commercial drone services are developing UAV services, sometimes called Drones as a Service (DaaS), to help industries, such as agriculture, construction, search and rescue, package delivery, industrial inspection, insurance and videography, with tasks like collecting imagery and measurements and managing or broadcasting events.
• Drone services seem cost-effective, portable, and – in extreme emergencies like Covid-19 can – provide the first take, including visuals, assessment and extent of damage.

Dekho Apna Desh webinar

The 13^th session of the Ministry of Tourism’s Dekho Apna Desh webinar titled, ‘Destination- Sariska Tiger reserve’ was held recently. The objective of the Ministry of Tourism’s webinar series is to create awareness about and promote various tourism destinations of India – including the lesser known destinations and lesser known facets of popular destinations.

Project Tiger

• Project Tiger is an ongoing Centrally Sponsored Scheme of the Ministry of Environment, Forests and Climate Change providing central assistance to the tiger States for tiger conservation in designated tiger reserves.
• The National Tiger Conservation Authority (NTCA) is a statutory body of the Ministry, with an overarching supervisory/coordination role, performing functions as provided in the Wildlife (Protection) Act, 1972. The NTCA was launched in 2005, following the recommendations of the Tiger Task Force. It was given statutory status by the 2006 amendment of Wildlife (Protection) Act, 1972.
• India now has as many as 2,967 tigers in the wild, with more than half of them in Madhya Pradesh and Karnataka, according to the latest tiger estimation report for 2018.
• The population of tigers have increased by 33% since the last census in 2014 when the total estimate was 2,226.
• Sariska is the first tiger reserve to have successfully relocated Royal Bengal tigers in India and at present there are around 20 tigers in the reserve.

Dekho Apna Desh

Dekho Apna Desh is one of the three components of the Paryatan Parv.The other two are Tourism for All and Tourism & Governance. It intends to encourage Indians to travel their own country.

Maple syrup urine disease (MSUD)

Maple syrup urine disease (MSUD) is a rare genetic disorder characterized by a deficiency of certain enzymes (branched-chain alpha-keto acid dehydrogenase complex) required to break down (metabolize) the three branched-chain amino acids (BCAAs) [Leucine, Isoleucine and Valine] in the body.

The result of this metabolic failure is that all three BCAAs, along with their various byproducts, accumulate abnormally throughout the body.

In the classic, severe form of MSUD, the plasma concentrations of the BCAAs begin to rise within a few hours of birth. If untreated, symptoms begin to emerge, often within the first 24-48 hours of life.

Symptoms of MSUD

The “non-specific” symptoms are those of increasing neurological dysfunction and include lethargy, irritability and poor feeding, followed soon by focal neurological signs such as abnormal movements and increasing spasticity, and shortly thereafter, by convulsions and deepening coma.

If untreated, progressive brain damage is inevitable and death ensues usually within weeks or months. The finding that is unique to MSUD is the emergence of a characteristic odor, reminiscent of maple syrup that can most readily be detected in the urine and earwax and may be smelled within a day or two of birth.

The disorder can be successfully managed through a specialized diet. However, even with treatment, both affected children and adults patients with MSUD remain at high risk for developing episodes of acute illness (metabolic crises) often triggered by infection, injury, failure to eat (fasting) or even by psychological stress. During these episodes there is a rapid, sudden spike in amino acid levels necessitating immediate medical intervention.

Types of MSUD

1. classic MSUD
2. intermediate MSUD
3. intermittent MSUD
4. thiamine-responsive MSUD
