About Mesolithic-era rock paintings in Guntur:-

• The time period of these paintings is estimated to be Mesolithic Age, roughly from 5000 BC.
• These paintings were made with “natural white kaolin and red ochre pigments”.
  • Ochre: a pigment composed of clay, sand, and ferric oxide.
  • Kaolinite: a soft, earthy, and usually white mineral produced by the chemical weathering of aluminum silicate minerals like feldspar.
• The social life and culture of the people who lived in the area are depicted through them.
  • One of the paintings depicted a man catching a wild goat with his left hand while wielding a hook-like implement to control it.
  • Another showed two couples standing with their hands raised while a child stood behind them.
  • The paintings depicted a person tilling a piece of land.
  • This can be an indication of a semi-settled life pattern in which members of this community cultivated crops.

• It is a thermo-stable vaccine, which does not require ultra-cold chain infrastructure used for other approved mRNA-based vaccines. This makes it easy for deployment all across India.
• It is delivered intra-dermally using a needle-free injection device system.
  • Intradermal injection: it is a shallow or superficial injection of a substance into the dermis (located between the epidermis and the hypodermis).
  • When administered intradermal in participants as a booster, it generates significantly higher immune responses.
• Available: for adults over the age of 18.
• Dosage: two doses will be administered intramuscularly 28 days apart.

mRNA vaccine

• It contains messenger RNA (mRNA). (UPSC CSE: mRNA Vaccine)
  • mRNA: it is a single-stranded RNA molecule that complements DNA.
• It is created in the nucleus when DNA is transcribed by RNA polymerase to create pre-mRNA.
• Working: mRNA vaccines work by introducing a piece of mRNA that corresponds to a viral protein.
• It is usually a small piece of protein found on the virus’s outer membrane.
• Individuals who get an mRNA vaccine will not be exposed to the same virus again.

Advantages of mRNA vaccines:-

• Safe: these are non-infectious, non-integrating in nature, and degraded by standard cellular mechanisms.
• Highly Efficient: they are highly efficacious because of their inherent capability of being translatable into the protein structure inside the cell cytoplasm.
• Faster to produce: mRNA vaccines are synthetic and do not require a host for growth, e.g., eggs or bacteria.
  • Therefore, they can be quickly manufactured.

Context: Recently, the debates about the conflict between the Union government and the Government of the National Capital Territory of Delhi (GNCTD) over the grant of Statehood to Delhi started again.

About Delhi Statehood:-

Background:

• There is an ongoing discussion regarding the conflict between the Union government and the Government of the National Capital Territory of Delhi (GNCTD) for the statehood grant to Delhi.

About Delhi Statehood:-

Historical Background:-

• After India attained independence on August 15, 1947, New Delhi was declared the capital of the Union of India.
• The Union Territory of Delhi was constituted from the Chief Commissioner’s Province of Delhi under the States Reorganization Act of 1956.
• The 69th Constitutional Amendment Act of 1991 conferred the UT of Delhi with a special status. (UPSC MAINS: Should Delhi be granted full statehood)
  • It re-designated Delhi as the National Capital Territory of Delhi .
  • It designated the administrator of Delhi (under Article 239) as the Lieutenant Governor (LG) of Delhi.
• These special provisions for Delhi were provided under Article 239AA.
• Article 239: Administration of Union territories.

Provisions under the Article 239AA 

• It provides for a legislative assembly and a council of ministers for Delhi.
• Legislative assembly of Delhi is empowered to make laws on all the matters of the State List (except public order, police and land) and the Concurrent List.
  • However, the laws of Parliament shall prevail over those made by the assembly in case of conflict.
• The Chief Minister of Delhi heads Council of Ministers of Delhi.
• It shall assists and advises the Lieutenant Governor (LG) in the exercise of his or her functions except in cases the LG has to act at his/her own
• If there is a difference of opinion between the ministers and the LG, the latter should refer the matter to the President of the country for a decision and act in accordance with that.
• The LG is also authorized to promulgate ordinances during the recess of the legislative assembly.

Issue of Statehood for Delhi

• Unlike the other Union Territories listed in Schedule 1 of the Constitution, Delhi has been given special status under Article 239 AA.
• However, there is an ever-going conflict with regard to the jurisdiction in the state due to which Delhi Government has been demanding a full statehood.

Need for statehood

Day-to-Day Problems

• The Delhi government lacks control over the transfers of officials, hindering their ability to manage the departments they were working in.

Frequent transfers:-

• Important officials are frequently transferred which minimizes the potential for effective governance.

Lack of Functional Control:–

• The elected government has no functional control over services.
• This results in challenges while punishing errant officers and addressing issues such as vacancies, vigilance enquiries, and corruption cases.

Conflicting Directives:–

• Officials are hesitant while following directives of the elected government due to being under the functional control of the LG.
• This creates confusion and hindered effective decision-making.

Lack of Answerability:

• The Services Department, under the control of the LG, have in the past refused to answer questions raised by Members of the Legislative Assembly (MLAs) in the Vidhan Sabha.
• This limits transparency and accountability, preventing MLAs from obtaining crucial information related to vacancies, corruption cases, and other issues.

Court’s Verdict and interpretations on the matter:-

• Supreme Court verdict, 2023: it stated that the government of Delhi possesses the authority to enact laws and oversee civil services in the national capital.
• The court restricted the jurisdiction of the Lieutenant Governor (LG) to bureaucrats in three distinct domains—public order, police, and land.

• Mains – GS 3 (Indian Economy)

Context: Semiconductor fabrication represents the ultimate frontier of human tech advancement.

About Semiconductors:

• Semiconductors are materials that have electrical conductivity between that of a conductor
  • Copper is a good conductor and Rubber is an insulator.
• This means that semiconductors can conduct electricity, but not as well as conductors, and they can also act as insulators, but not as effectively as insulators.
• This property allows for the creation of electronic components with specific electrical properties; enable the design of complex circuits and devices.
• Semiconductors are typically made from materials such as silicon, germanium, and gallium arsenide.

India’s semiconductor sector:

• The country’s electronics and semiconductor products manufacturing sector has witnessed a quantum growth in the last almost a decade.
• Import and manufacturing:
  • In 2014, some 92% of the mobile devices sold in the country were imported while in 2022 some 97% of mobile devices were manufactured in the country.

The global semiconductor industry:

• The global semiconductor industry is currently valued at $500-$600 billion and caters to the global electronics industry currently valued at about $3 trillion.
• The chip-making industry is a highly concentrated one, with the big players being Taiwan, South Korea and the U.S. among others.
• 90% of five nm (nanometer) chips are mass-produced in Taiwan, by the Taiwan Semiconductor Manufacturing Company (TSMC).

Applications of semiconductors:

• Electronic devices: Semiconductors are the basis transistors, diodes, integrated circuits, microprocessors, and memory chips, which are used in electronic devices such as computers, smart phones, televisions, radios, and more.
• Solar cells: They are used in manufacture of solar cells, which convert sun light into electricity.
• Lighting: They are used in light-emitting diodes (LEDs) to produce energy-efficient lighting.
• Sensors: They are used in power-electronics, which are used to control and convert electrical power.

Challenges associated with the industry:

Setting up of Semiconductor fabs:

• Semiconductor fabrication represents the ultimate frontier of human tech advancement. However, the progress of miniaturisation is accompanied by higher complexity and costs.
• Investment in a semiconductor fab is one of the riskiest. Billions of dollars need to be recovered before the technology becomes obsolete.

Challenges of chip manufacturing:

• Developing an ecosystem for chip manufacturing in a Greenfield location is a major challenge.
• Hundreds of chemicals and gases are required for chip fabrication, people need to be trained, and abundant clean water be made available. Above all is the art of chip making.
• Despite the best of equipment, poor quality and low yields can make fabs fail.

Need for an advanced technology:

• There are other issues, such as whether to set up a logic/processor, memory or analog fab.
• Electronic equipment and its functionalities are characterized by their logic chips, which are therefore strategically important and generate the highest profit.
• The most advanced set of technologies is needed to manufacture them.

China’s monopoly in the sector:

• Elaborating on the opportunities for India currently, he said electronics and semiconductor products today was a $1.5 trillion industry with China solely accounting for almost 75% of it and having enjoyed a monopoly in the sector for over two decades now.

Lessons for India from China:

• Acquiring existing fabs offers several advantages, including reasonable pricing, established technology, a supply chain ecosystem, an existing product line, and an established market.
  • By acquiring these fabs, India can build its fab ecosystem and train its human resources.
• Moreover, lower subsidies would be required for such acquisitions, allowing the saved funds to be utilized for advanced research and development (R&D) in fab technologies.
  • This, in turn, would contribute to the development of a state-of-the-art fab in the coming years.
• Another strategy is the establishment of Assembly, Testing, Packaging, and Marking (ATMP) facilities.
  • Tessolve, which is now owned by the Tatas, set up an ATMP in 2013-14.
  • This ATMP has been successful in packaging chips with a feature size of up to seven nm. China, on the other hand, has more than 100 ATMPs.

Way Forward:

India’s pursuit of a semiconductor fab faces various challenges and uncertainties. By examining the reasons behind past failures and considering alternative approaches, India can learn valuable lessons from China’s successful semiconductor industry.

Acquiring existing fabs, developing ATMPs, and investing in advanced R&D can help India establish a robust fab ecosystem and compete in the global chip warfare. The urgency to act now, despite trailing China in this journey, remains crucial for India’s future success in the semiconductor industry.

• Mains – GS 3 (Environment)

Context: Delta Air Lines in 2020 marketed itself as the “world’s first carbon-neutral airline”, but recently California-based Mayanna Berrin filed a lawsuit against Delta arguing that the airlines’ assertions were bogus, misleading and false.

About Carbon Offsetting:

• It’s a slew of ways companies adopt to reduce or remove carbon emissions from the environment.
  • Activities like planting trees, shifting to cleaner fuel and funding carbon capture techniques in theory balance out a company’s carbon emissions.
• Examples:
  • Forestry: Tree planting projects restore areas facing deforestation. Trees absorb and hold carbon. Without them, that carbon would be in the atmosphere, making global warming worse.
  • Agriculture: Farmers grow crops using technology and techniques to maximize resources and reduce waste when growing crops.
  • Aviation: Airline operators optimize flight paths with AI to minimize the creation of contrail clouds.
  • Renewable energy: These projects replace fossil fuel use with clean, renewable energy, such as that generated from a wind farm.

Positive Effects of Offsetting

• These programmes have the particular benefit of being a crucial step in resolving the CO2 issue and, when carried out properly, may provide noticeable improvements.
• Businesses may take action to offset their emissions and make significant strides toward sustainability rather than continuing to pollute.
• In locations where they are most needed, carbon offset programmes can directly contribute to programmes that benefit communities and the environment.
• They also offer the additional advantage of transferring financial resources from developed countries to underdeveloped ones in a market worth up to $120 billion.
• Funds for carbon offsets help developing nations create green infrastructure, make better use of their natural resources, and enhance the quality of their air, water, and land.
• Investing more money in green businesses may also provide economies of scale benefits, such as decreasing the price of solar and wind farms or creating innovative new technologies like direct air capture.

Problems with carbon offsets:

• In genuineness: Most of world’s carbon offsets certifier do not represent geniuses in carbon reductions.
• Lack of alternatives: Mostly planting trees are considered to reduce emissions and there are only few alternatives to reduce emissions.
• Same mechanisms for all companies: Planting trees or other alternatives cannot reduce emissions for all companies.
• Cheaper carbon credit: The expense of carbon credit are cheaper than reducing carbon emission so companies mostly prefer carbon credits.
• Regulation: Lack of regulation to carbon offsets industry.
• Lack of technology: In carbon technologies to capture carbon directly to offset carbon.
• Greenwashing: Most companies adhere to the greenwashing via avoidance offsets projects.

Govt. of India Initiatives:

• PAT (Perform, Achieve and Trade), a market-based scheme, has already prevented CO2 emissions of up to 92 million tonnes during its 1st and 2nd cycles.
• Indian Carbon Market (ICM): with an objective to decarbonize the Indian economy by pricing GHG emissions through trading of carbon credit certificates and in compliance with Article 6.2 of the Paris Agreement.
• Carbon Credit Trading Scheme that is expected to be notified in June 2023 with Carbon Credit Certificates under it are expected to be available for trading by 2025.

Way Forward:
