{GS1 – Geo – EG – Mineral Resources – 2023/08/21} Sapphire Mines

  • Context (AIR I HT): In J&K, Sapphire mines, of Paddar in Kishtwar district will be auctioned in a scientific way to boost the local economy.

About Sapphire

  • The word Sapphire comes from the ancient Latin and Greek used for term “blue”.
  • Sapphire is a type of mineral called “Corundum”, which is composed of aluminium oxide.
  • Corundum can have various colours, such as red, pink, yellow, orange and violet, besides blue.


Distribution of Sapphires Worldwide

  • Sri Lanka remains a major source of natural sapphire, which is founded in many parts of the world.
  • Corundum, the mineral that sapphire belongs to, is also present in India along with kyanite and sillimanite in the states of Assam, Meghalaya and Maharashtra.
  • Syenites and ultrabasic rocks in Telangana contain corundum as well.
  • The estimated reserves/resources of Sapphire in India are 450 kg, all of which are in the ‘Remaining Resources’ category and are located in J&K.


  • Sapphire has emerged as a versatile material useful to a range of industries in many varied applications including LEDs, Optical and Radio Frequency Integrated Circuits.

Why is Kashmir sapphire famous?

  • Kashmir Sapphire is famous for its exceptional quality, rarity, and beauty.
  • Kashmir sapphire was discovered in the late 19th century in the remote Zanskar range of the Himalayas, and the original mines were soon exhausted.
  • Since then, only a few new sapphires have been found in Kashmir, making them extremely scarce and valuable.
  • Kashmir sapphire is also highly sought after because it is usually untreated, unlike most of the sapphires on the market that are heated to improve their colour.
  • It is also known to produce asterism or a star effect when cut as a cabochon.
  • This is caused by the reflection of light from microscopic particles aligned along the crystal axes.
  • Cabochon: A cabochon is a gemstone that has been shaped and polished, as opposed to faceted.
    • The resulting form is usually a convex obverse with a flat reverse.


{GS1 – Geo – PG – Climatology – 2023/08/21} Hurricane Hillary

  • Context (IE): Hurricane Hillary in a unprecedented way battering California and Mexico.
  • As per latest estimates, the hurricane will make landfall in the Baja peninsula in Mexico.
  • Tijuana, a border metropolis in Mexico, is at risk of landslides and flooding, because of its hilly terrain, extremely high density of population, and poor quality of housing and infrastructure.

Tropical Cyclones

  • A cyclone is a system of high-speed winds rotating around a low-pressure area (developed over warm waters). It blows counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
  • Tropical cyclones are cyclones that originate over tropical oceans in late summer.

Hurricane Hilary Time

Why Hurricane Hillary is Unprecedented/Rare?

  • Hurricane Hillary is Category 4 storm that have formed over the eastern Pacific Ocean and is currently inland over California.
  • Though Florida, Louisiana and Texas on the Gulf of Mexico, face the havoc of hurricanes, but California and Mexico in the west, seldom faces it.

Reasons Why East Pacific coast Seldom Sees Tropical Storms and Hurricanes

Ocean Waters Temperature
Ideal Condition
  • Ocean waters must be above 26°C, so that, they can act as the source of moisture for the storm.
  • The condensation of moisture releases enough latent heat of condensation to drive the storm.
  • Below this threshold temperature, hurricanes will not form or will weaken rapidly.
East Pacific Coast Condition
  • East Pacific Coast (or Western US coast) remains below 26°C during the hurricane season.
  • This happens because the cold current steers colder water from higher latitudes toward equatorial regions along the East Pacific coast.
Vertical Wind Shear
Ideal Condition
  • Wind shear means differences between wind speeds at different heights.
  • Hurricanes develop when the wind shear low.
  • They can’t emerge if the upper level wind shear is strong as it destroy the storms structure by displacing the warm temperatures above the eye and limiting the vertical accent of air parcels.
East Pacific Coast Condition
  • Wind shear in the eastern Pacific is much stronger than the Gulf of Mexico, causing less frequent hurricanes along the western coast.
Wind Steering Patterns
Ideal Condition
  • Wind steering in the context of hurricanes refers to the process by which the movement and behavior of a hurricane are influenced by the surrounding atmospheric flow patterns.
  • For a coast to be hurricane-prone, the wind steering pattern must direct the hurricanes toward it.
East Pacific Coast Condition
  • Trade winds play a crucial role in directing hurricanes in the Pacific Ocean and they divert hurricanes away from the Pacific East coast (or Western US coast).

Other Ideal Conditions Necessary for the Formation of a Tropical Cyclone (or Hurricane)

  • Apart from ocean waters temperature above 26°C and low vertical shear, other necessary for the formation of a hurricane are:
Presence of the Coriolis force enough to create a cyclonic vortex
  • Coriolis force is zero at the equator (no cyclones at equator because of zero Coriolis Force) but it increases with latitude.
  • Coriolis force at 5° latitude is significant enough to create a storm (cyclonic vortex).
  • About 65% of cyclonic activity occurs between 10° and 20° latitude.
Low-pressure Area
  • Existence of low pressure area acts as the seed for cyclone.
  • Air flows from areas of higher pressure to lower pressure, creating circulating winds around the center of the low-pressure system.
Upper-level divergence
  • A well-developed divergence in the upper layers of the atmosphere is necessary so that the rising air currents within the cyclone continue to be pumped out and a low pressure is maintained at the centre.
Temperature Contrast Between Air Masses
  • The convergence of air masses of different temperatures results in instability causing low-level disturbances (low-pressure cells) which are a prerequisite for the origin and growth of violent tropical storms.

Origin, Development & Evolution of a Tropical Cyclone

{GS2 – Education – Issues – 2023/08/21} TN CM Wants Education Back in State List

  • Context (TH): The Tamil Nadu CM called for transferring education back to the State List of the Seventh Schedule of the Constitution.
  • The CM’s remarks came in the aftermath of the TN Governor declining to provide his assent to the TN State government’s bill seeking exemption from the NEET.

National Eligibility and Entrance Test (NEET)

  • It is an all-India entrance test for admission to undergraduate medical courses.
  • NEET has been conducted since 2013.


  • Some States are opposing the NEET on the following grounds:
    • NEET fosters inequity and benefits affluent candidates who can afford expensive coaching.
    • The centralised admission test causes a monetary burden and inconvenience for students.
    • The national level tests favour students from the Central Board of Secondary Education (CBSE) (Close to 59% of the shortlisted students in IIT JEE were from the CBSE Board alone).
    • It undermines the autonomy of the States on education matters.

(Update) Exemption for TN

  • Is it possible to exempt Tamil Nadu from NEET for admissions to medical courses?
    • Yes. If the President gives a nod to TN government’s Bill to exempt TN from NEET, TN will be exempted and will have state level exam for admission to medical courses.

Education in India

  • The IC, in its original enactment, defined education as a State subject.
  • The 42nd Constitutional Amendment Act of 1976 moved education to the concurrent list.
  • The 86th Constitution Amendment Act inserted Article 21A in the IC, making education a Fundamental Right for Children aged 6 to 14 years.
  • Right to Education (RTE) Act, 2009, provides free and compulsory education to all children aged 6 to 14 years.

Education as a concurrent subject

  • It allows for flexibility and coordination between the central and state governments.
  • It enables the central government to set specific national-level educational standards and policies while permitting states to address local needs and issues in education.

Seventh Schedule of the IC

  • It divides legislative powers between the central government (Union) and the state governments.
  • The distribution of powers helps maintain a balance between the central government’s authority and the autonomy of the state governments.
  • It contains three lists:
    1. Union List
    2. State List
    3. Concurrent List
  1. Union List: This list includes subjects on which only the central government can make laws.
    • Examples: Defense, Foreign Affairs, Banking, Currency, and Atomic Energy.
  2. State List: This list consists of subjects on which only the state governments can make laws.
    • Examples: Police, Public Health, Agriculture, Land, and Local Government.
  3. Concurrent List: This list includes subjects on which both the central and state governments can make laws. However, the central law prevails in case of a conflict between central and state laws.
    • Examples: Criminal Law, Marriage, Education, Forests, Protection of Wild Animals, etc.
  • Additionally, the Residuary Power belongs to the Central Government, allowing it to legislate on matters not mentioned in any list.

42nd Constitutional Amendment Act of 1976

  • It moved the following subjects from the State list to the Concurrent list:
    1. Education
    2. Forest
    3. Protection of wild animals and birds
    4. Weights and measures
    5. Administration of justice, constitution, and organisation of all courts except the supreme court and high courts.

{GS2 – Health – Initiatives – 2023/08/21} GIDH

  • Context (WHO | TH): The World Health Organization (WHO) and the G20 India presidency announced a new Global Initiative on Digital Health (GIDH).
  • Global Initiative on Digital Health (GIDH) is a WHO-managed network (Network of Networks) of stakeholders to facilitate:
    • Implementation of the Global Strategy on Digital Health 2020-2025.
    • Other WHO norms and standards for Digital Health System Transformation.
  • It is a platform to enable a global ecosystem to work collectively to promote country capacity and strengthen international cooperation in digital health.
  • It will promote equitable access to digital health by addressing challenges such as duplication of efforts and “products-focused” digital health transformation.

Four foundational pillars

Global Initiative on Digital Health (GIDH)

  1. Country Needs Tracker: GIDH will ensure that digital health investments are informed by country priorities.
  2. Country Resource Portal: It will analyse the resourcing gaps in digital health.
  3. Transformation Toolbox: Quality-assured tools and resources will strengthen the country’s capacity to manage its national digital health transformation journey.
  4. Convening and Knowledge Exchange: Promoting strengthened collaboration and knowledge exchange across global, regional, and national networks in digital health.

GIDH and G20 Theme

  • GIDH will ultimately aim to align efforts to support the Global Strategy on Digital Health 2020–2025.
  • This sharing approach is linked to India’s philosophy of “Vasudhaiva Kutumbakam” (whole world is one family).

Digital health

  • It is a proven accelerator to advance health outcomes and achieve Universal Health Coverage (UHC) and health-related Sustainable Development Goals.

WHO’s first resolution on ehealth (2005)

  • In 2005, the World Health Assembly through its resolution on eHealth urged Member States:
    • To consider drawing up a long-term strategic plan for developing and implementing eHealth services.
    • To develop the infrastructure for information and communication technologies for health.
  • To promote equitable, affordable, and universal access to their benefits.
  • Over 120 WHO Member States have developed a national digital health policy or strategy.

Global Strategy on Digital Health 2020-2025

  • It was adopted by the World Health Assembly in 2020.
  • It presents a roadmap to link the latest developments in innovation and digital health, and use this tool to improve health outcomes.
  • The purpose is to support countries in strengthening their health systems through the application of digital health technologies and achieve the vision of health for all.

Health and SDGs

  • SDG 3, “Good Health and Well-Being,” calls on countries to ensure healthy lives and promote well-being for all at all ages.
  • Almost all of the other sixteen goals are directly related to health or will contribute to health indirectly.

{GS2 – IR – Groupings – 2023/08/21} BRICS

  • Context (TH): PM Narendra Modi is set to visit South Africa for the BRICS Summit.
  • BRICS is a grouping of the world economies of Brazil, Russia, India, China, and South Africa formed in 2010.

Evolution of BRICS

  • In 2001, British economist Jim O’Neill coined the term ‘BRIC’, standing for the initials of four emerging economies at the time – Brazil, Russia, India, and China.
  • The leaders of BRIC (Brazil, Russia, India, and China) countries met for the first time in St. Petersburg, Russia in July 2006.
  • In September 2006, the group was formalised as BRIC.
  • The first formal meeting was held in 2009 in Russia. South Africa joined in 2010, expanding it to ‘BRICS’.
  • Now, BRICS includes these five economies, representing:
    • 42% of the world’s population
    • 30% of the world’s territory
    • 23% of global GDP
    • 18% of world trade.

Rationale behind creating BRICS

  • To counter the dominance of European and Western countries at international forums and institutions, such as the United Nations.
  • To represent global south at the centre of international agenda-setting.

BRICS agenda

  • The chairmanship rotates among the group annually.
  • The Chair has to set the agenda, priorities, and calendar for the year.
  • This year, the agenda of the 15th Summit is ‘BRICS in Africa: Partnership for Mutually Accelerated Growth, Sustainable Development and Inclusive Multilateralism’.

Importance for India

  • The platform could be a means of establishing its larger efforts to represent the Global South.
  • The Summit could move things along from a diplomatic perspective.
  • This is the first in-person summit since the military standoff with China at the Line of Actual Control began in 2020. This meeting could resolve the LAC situation.
  • Just over two weeks after the BRICS summit, India will host the G20 summit, and India will want to ensure full attendance by the leaders including all BRICS members.
  • The 2017 Doklam stand-off at the Bhutan-India-China trijunction was resolved just days before Modi and Xi were scheduled to meet for the then BRICS summit in China.
  • All BRICS countries are members of G20.

New Development Bank (NDB/BRICS Bank)

  • NDB formally came into existence as a legal entity in 2015 on the eve of the Ufa summit.
  • It was established by BRICS member states in 2016.
  • It has its headquarters in Shanghai, China.
  • In 2018, the NDB received observer status in the UN General Assembly.
  • Its objective is to support the infrastructure and sustainable development projects in BRICS and other emerging economies, as well as in developing countries.
  • The NDB President is elected on a rotational basis from one of the founding members, and there are four Vice Presidents from each of the other four founding members.
  • K.V. Kamath from India was the first elected president of the NDB.


  • All members of the United Nations could be members of the bank; however, the share of the BRICS nations can never be less than 55% of voting power.
  • As of now, nine countries are members of BRICS.
    • All BRICS members are members of NDB.
    • NDB admitted Bangladesh, United Arab Emirates (UAE), Egypt and Uruguay as its new members in 2021.
    • NDB included UAE as a prospective member.
  • Prospective members: Members that have been admitted by NDB’s Board of Governors and will officially become a member country once they deposit their instrument of accession.

Contribution and Voting

  • The New Development Bank have an initial subscribed capital of US$ 50 billion and an initial authorized capital of US$ 100 billion.
  • The initial subscribed capital is equally distributed amongst the founding members. The voting power of each member shall equal its subscribed shares in the capital stock of the Bank.
  • Each member cannot increase its share of capital without all other four members agreeing.

{GS2 – MoCA – Measures – 2023/08/21} Flight Duty Time Limitation

  • Context (TH | IE): After instances of pilots dying of cardiac arrests and pilots complaining of fatigue, there are growing concerns regarding the adherence to Flight Duty Time Limitation (FDTL) norms.

What is Pilot Fatigue?

  • Pilot fatigue (or flight crew fatigue) refers to the state of physical and mental exhaustion which results in impaired cognitive function, decreased alertness, and reduced decision-making abilities of the pilots.
  • It is a significant concern in aviation safety.
  • Key factors contributing to pilot fatigue include:
    • Long Duty Hours
    • Time Zone Changes
    • Overnight Operations
    • Unpredictable Schedules
    • Pressure to Fly
    • Sleep Disruption
    • Cabin Conditions

Flight Duty Time Limitation (FDTL)

India civil aviation, Safety limits to flying

  • FDTL is a set of regulations that limit the number of hours that pilots can fly and the number of consecutive days that they can work.
  • These regulations are designed to prevent pilot fatigue, which can lead to accidents.
  • The FDTL regulations vary from country to country.
  • Smaller airports are usually more susceptible to FDTL-related disruptions because they are unlikely to have standby crew, and it is difficult to mobilise them at short notice.

Flight Duty Time Limitation (FDTL) in India

  • In India, the FDTL regulations are set by the Directorate General of Civil Aviation (DGCA).
  • The following are the FDTL regulations for pilots in India:
    • Flight time: A pilot can fly a maximum of 8 hours in a day.
    • Duty period: A duty period is the time from the pilot’s report time to the end of the flight. A pilot can work a maximum of 13 hours in a duty period.
    • Rest period: A rest period is the time between duty periods. A pilot must have a minimum of 10 hours of rest between duty periods.
    • Cumulative flight time: A pilot can fly a maximum of 35 hours in a week.
    • Cumulative duty period: A pilot can work a maximum of 90 hours in a 28-day period.
  • These are just the general FDTL regulations.
  • There are specific regulations for different types of flights, like night flights and international flights.

{GS3 – Agri – Marketing – 2023/08/21} Warehouse Receipt

  • Context (PIB): Warehousing Development Regulatory Authority (WDRA) organized one day conference on electronic-Negotiable Warehouse Receipts (e-NWR).
  • Warehouse Receipt (WR) is a form of documentation used within futures markets to ensure the quality and quantity of a particular commodity stored within an approved facility.
  • Instead of moving the actual goods under contract immediately, these receipts are used to settle futures contracts.
  • It can be negotiable or non-negotiable.

Negotiable Warehouse Receipt (NWR)

  • A warehouse receipt is negotiable if the goods are to be transferred to another party.
  • Farmers can seek loans from banks against these receipts issued to them against their storage.
  • These receipts issued by the warehouses registered with the WDRA.

Benefits of NWR

  • It helps the farmers:
    • To avoid distress sales of agricultural produce during the peak marketing season
    • To avoid the post-harvest storage loss
    • To increase the income

Non-negotiable Warehouse Receipt

  • A warehouse receipt is non-negotiable if the goods are not transferable.
  • It serves as proof of storage or possession.

Types of Negotiable Warehouse Receipt (NWR)

Paper based NWR

  • WDRA initially implemented paper based NWR system. But there were many risks involved in the paper-based warehouse receipts. Such as:
    • Risk of fudging, overwriting, damage, loss, etc
    • Issuance of WR without receiving goods
    • Issuance of duplicate WR without following the procedure
    • Issuance of multiple WRs for the same stock
    • Possible delivery of stocks without surrenders of warehouse receipt.
  • So, in 2014-15, WDRA initiated the implementation of IT based platform for registration of warehouses and setting up Repositories for issuance of NWRs in electronic form (e-NWR)

Electronic NWR (e-NWR)

  • It was launched in 2017.
  • It can be used for deposit and withdrawal of commodities as well as trade transactions.
  • It can be traded through off-market or online trading platforms.
  • It has been integrated with the electronic National Agriculture Market (e-NAM) platform by providing an interface between e-NAM and repositories.
  • It can be auctioned under certain conditions such as:
    • Loan not repaid.
    • Delivery not taken on expiry.
    • Damage or spoilage of the commodity in the warehouse

Warehousing Development and Regulatory Authority (WDRA)

  • It was setup in 2010 under the Warehousing (Development and Regulation) Act, 2007 by Ministry of Consumer Affairs, Food and Public Distribution.
  • The main objective of WDRA is to implement Negotiable Warehouse Receipt (NWR) System in the country.
  • It helps farmers:
    • To store their produce in scientific storage godowns near by their farms
    • To seek loan from banks against their NWR.

Functions of WDRA

  1. Registration of warehouses
  2. Regulations of negotiability of warehouse receipts
  3. Promotion of scientific warehousing of goods
  4. Improving fiduciary trust of depositors and banks
  5. Enhancing liquidity in rural areas
  6. Promoting efficient supply chain

{GS3 – Agri – Schemes – 2023/08/21} National Food Security Mission-Pulses

  • Context (PIB | TH): Information regarding National Food Security Mission (NFSM)-Pulses and PM-AASHA was provided in the Rajya Sabha regarding pulses.
  • Moreover, though the production of pulses is increasing in recent years, but, pulses prices may spiral this year due to deficient rain.
  • Sown area for pulses has declined than last year and till now has not shown any recovery.

Progress in Sowing Area of Pulses


  • Pulses (or legumes) are the edible seeds of leguminous plants cultivated both for food and feed.
  • Pulses are different from crops; pulses are harvested when the seeds become dry whereas crops are harvested when plants are still green.
  • Dried beans, lentils, and peas are the most consumed types of pulses.
  • Pulses do not include leguminous plants that are:
    • Harvested green (e.g., green peas, green beans; these are classified as vegetable crops)
    • Used for oil extraction (e.g., soybean and groundnuts)
    • Used exclusively for sowing purposes (e.g., seeds of clover and alfalfa)
  • Leguminous plants: Plants that have nodules in their roots that contain nitrogen-fixing bacteria (Rhizobium).

Climate Change and its effect on Pulses Sowing

  • Ideal growing conditions for pulses:
    • Temperature: Between 20-27°C
    • Rainfall: Around 25-60 cm
    • Soil Type: Sandy-loamy soil is best. But it can also be grown in well-drained alluvial, loamy, and moderately acidic, and saline soil.

World Pulse Day

  • Every year, February 10th is celebrated as World Pulse Day.
  • The aim is to aware people of the importance of pulses as a global staple food.
  • World Pulses Day, 2023 theme: Pulses for a Sustainable Future.

Significance of Pulses

Nutritional Value
  • Pulses have high protein content; they are ideal source of protein where meat and dairy are physically or economically not accessible and for people with vegetarian and vegan diets.
  • Pulses are low in fat and sodium and rich in soluble fibre, and iron.
  • Because of these qualities, they can lower cholesterol and control blood sugar and help combat diabetes, heart diseases, and obesity.
Food Security
  • Farmers can both sell and consume pulses. Thus, it helps farmers maintain household food security and creates economic stability.
Agricultural Benefits
  • The nitrogen-fixing properties of pulses improve soil fertility, which increases and extends the productivity of the farmland.
  • Using pulses as intercropping and cover crops, helps farmers in:
    • Increasing yield
    • Reducing the risk of crop failure due to pest and disease attacks
    • Suppressing weeds
    • Nutrient cycling
    • Water use efficiency
    • Crop diversification
    • Pest and disease management
  • Intercropping: It is an agricultural practice in which two or more crops are grown together in the same field.
  • Cover crop (or green manure crop): It is a type of crop grown to benefit the soil, rather than for harvest or consumption. Cover crops are planted to cover and protect the soil between main crop plantings, during fallow periods, or as part of a crop rotation system.
Environmental Benefit
  • Pulses can help in climate change mitigation by reducing dependence on the synthetic fertilizers used for adding nitrogen into the soil.
  • Greenhouse gases are released during the manufacturing and application of these synthetic fertilizers which is detrimental to the environment.
Drought Resistant
  • Pulses require lower water than other food crops, so, they can withstand drought.
  • They are important for combating water scarcity resulting from climate change and for improving the income of farmers in drought-prone regions.
Help Achieve Sustainable Development Goals (SDGs):
  • Because of their drought-resistant, high nutrient, and soil fertility-improving qualities, they can help to achieve SDGs 2, 3, and 13.
    • Goal 2: Zero Hunger – End hunger, achieve food security and improved nutrition, and promote sustainable agriculture
    • Goal 3: Good Health and Well-Being – Ensure healthy lives and promote well-being for all at all ages
    • Goal 13: Climate Action – Take urgent action to combat climate change and its impacts by regulating emissions and promoting developments in renewable energy

Pulses in India

  • India is the largest producer (25% of global production), consumer (27% of world consumption), and importer (14%) of pulses in the world.
  • They account for around 20% of the area under foodgrains and contribute around 7-10% of the total foodgrains production in the country.
  • They are grown in Kharif, Rabi, and Zaid seasons, but Rabi pulses contribute 60% of the total production.
  • In India, gram is the most dominant pulse (40% of the total production) followed by Tur/Arhar (15-20%) and Urad (Black Matpe) and Moong (8-10% each).
  • Top pulses producing states: Madhya Pradesh (1st)> Maharashtra (2nd) > Rajasthan (3rd) > Uttar Pradesh (4th) > Karnataka (5th)

Major Pulses of India



Kharif Arhar (pigeon pea), urad (black gram), moong (green gram), barbati (cow pea), rajma (in hills)
Rabi Gram, pea, rajma (in plains), masoor (lentil)
Zaid Urad, moong, cow pea

Major Pulses Producing States

National Food Security Mission (NFSM)

  • NFSM is a centrally sponsored scheme launched in 2007 under the Ministry of Agriculture & Farmers Welfare.
  • Aim of NFSM: increasing the production of food grains through area expansion and productivity enhancement.

Components of NFSM

  • The mission has the following five components:
    1. NFSM – Rice
    2. NFSM – Wheat
    3. NFSM – Pulses
    4. NFSM – Coarse Cereals and
    5. NFSM – Commercial Crops

Key Interventions Under NFSM-Pulses

  • Under the mission, assistance is given through States/UTs to the farmers for interventions like:
    • Cluster demonstrations on the improved package of practices
    • Demonstrations on cropping system, seed production, and distribution of HYVs/hybrids
    • Improved farm machinery, resource conservation machinery, and tools
    • Efficient water application tools
    • Plant protection measures
    • Nutrient management/soil ameliorants
    • Processing & post-harvest equipment
    • Cropping system-based trainings etc.

Other Initiatives NFSM-Pulses

  • Distribution of seed mini-kits of new varieties of pulses
  • Production of quality seed
  • Technological demonstration by Krishi Vigyan Kendras (KVKs)
  • Establishment of Seed Hubs to augment the availability of quality seeds

Pradhan Mantri Annadata Aay SanraksHan Abhiyan (PM-AASHA)

  • GoI has implemented an umbrella scheme PM-AASHA to ensure Minimum Support Price (MSP) to farmers for their produce.

Three Components of PM-AASHA

Price Support Scheme (PSS)
  • In PSS, physical procurement of pulses, oilseeds, and copra will be done by Central Nodal Agencies with the proactive role of State governments.
  • The National Agricultural Cooperative Marketing Federation of India (NAFED), and the Food Cooperation of India (FCI) will take up PSS operations in states/districts.
  • The procurement expenditure and losses due to procurement will be borne by GoI.
Price Deficiency Payment Scheme (PDPS)
  • Under PDPS, it is proposed to cover all oilseeds for which MSP is notified.
  • In this direct payment scheme, the difference between the MSP and the selling/modal price will be made to pre-registered farmers.
  • All payments will be done directly into the registered bank account of the farmer.
  • This scheme does not involve any physical procurement of crops.
Private Procurement Stockist Scheme (PPSS)
  • Under PPPS, the private sector will take part in the procurement operations.
  • Therefore in addition to PDPS, states have the option to roll out PPSS on a pilot basis in selected districts/ Agricultural Produce & Livestock Market Committees (APMC) for oilseeds procurement.

Minimum Support Price for Pulses

  • Minimum Support Price (MSP) is a minimum price set by the government for certain agricultural commodities to protect farmers from fluctuations in market prices and ensure a minimum level of income for their produce.
  • Simply, the MSP is the rate at which the government buys grains from farmers.
  • The MSPs are fixed by the Central government on the recommendations of the Commission for Agricultural Costs and Prices (CACP) under the Ministry of Agriculture.
  • After receiving the feedback Cabinet Committee on Economic Affairs (CCEA) of the Union government takes a final decision on the level of MSPs.
  • The Food Corporation of India (FCI), the nodal agency, along with other State Agencies undertakes procurement of crops.
  • The MSPs are announced before the sowing season by the government.
  • The government is not legally bound to pay the MSP to farmers.
    • So, though the government encourages the procurement of crops at MSP through its agencies, there is no legal obligation for the government to purchase all crops at MSP or to compensate farmers if market prices fall below the MSP.
  • GoI fixes MSPs for 23 farm commodities based on CACP recommendations:
    1. 7 cereals (paddy, wheat, maize, bajra, jowar, ragi, and barley)
    2. 5 pulses (chana, arhar/tur, urad, moong, and masur)
    3. 7 oilseeds (rapeseed-mustard, groundnut, soyabean, sunflower, sesamum, safflower, and nigerseed)
    4. 4 commercial crops (cotton, sugarcane, copra, and raw jute)
  • In addition, GoI also fixes the MSP of toria and de-husked coconut on the basis of the MSPs of rapeseed/mustard and copra respectively.

{GS3 – S&T – Tech – 2023/08/21} 3D-Printed Post Office

  • Context (TH I IE): India’s First 3D-Printed Post Office was inaugurated in Bengaluru, built by L&T Limited with support from IIT Madras, and completed in just 43 days.

3-D Printing, Applications and IssuesWatch | Now, a 3D printed post office building coming up in Bengaluru - The Hindu India's first 3D printed post office is now open for business in Bengaluru - The Hindu

3D Printing

  • 3D printing is a process of creating Three-Dimesional objects from digital models by adding material layer by layer.
  • It involves building up layers of materials like plastic, composites, or bio-materials to construct objects with varying shapes, sizes, rigidity, and colour.
  • This process allows for more efficient and customized production compared to traditional subtractive manufacturing methods.

What are Megaliths?

  • Megaliths are large stones used to construct prehistoric structures or monuments, either alone or with other stones.
  • They were built as either burial sites or commemorative memorials.
  • In India, most megaliths date back to the Iron Age (1500 BC to 500 BC), though some sites precede the Iron Age, extending up to 2000 BC.

Different Types Of Megalithic Structures

  • Stone Circles: Also known as “cromlechs, these are circles of standing stones, often used for ceremonial or astronomical purposes.
  • Dolmens: These structures consist of a large capstone supported by two or more upright stones, forming a chamber below. They were often used as tombs or burial chambers.
  • Cists: These are small, stone-built coffin-like boxes used to hold the bodies of the dead. They were often buried underground and could be single- or multiple-chambered.
  • Monoliths: These are single-standing stones erected in prehistoric times. The term is sometimes used interchangeably with “megalith” and “menhir.
  • Capstone style: This refers to single megaliths placed horizontally over burial chambers, without the use of support stones.

Key findings

  • Hat stones, popularly called Thoppikkallu in Malayalam, are hemispherical laterite stones used as lids on burial urns during the megalithic period and are found here.
  • The findings may throw light on the life and culture of people who lived in Kuttippuram village, near Tirunavaya, Kerala more than 2,000 years ago.
