Foreign Policy Watch: India-China

What if China stops Brahmaputra Water? 

Why in the News?

Assam CM Himanta Biswa Sarma dismissed Pakistan’s claim about China blocking the Brahmaputra’s water as a baseless panic tactic with no scientific substance.

Sarma’s Clarification on the Brahmaputra Issue:

  • Brahmaputra is an Indian river and not fully controlled by China.
  • Only about 30–35% of the river’s flow comes from China, mainly through glacial melt and rainfall on the Tibetan Plateau.
  • A major 65–70% of the river’s volume is generated within India, especially from monsoon rains and Indian tributaries.
  • He explained that the river’s flow increases from 2,000–3,000 cubic metres/second at the Indo-China border to 15,000–20,000 m³/s in Assam during the monsoon.
  • This proves that India plays a dominant role in sustaining the river, not China.
  • Even if China tried to restrict the river’s flow, it could help reduce annual floods in Assam that displace thousands of people.
  • He confirmed that China has never threatened to weaponize the Brahmaputra.

About Brahmaputra River System:

  • The Brahmaputra River System is one of the major Himalayan drainage systems, along with the Ganga and Indus.
  • Stretch: It stretches over 2,900 kilometres, making it one of the longest rivers in Asia.
  • Origin: It originates in the Chemayungdung glacier in southwestern Tibet, where it is known as the Tsangpo River.
  • Catchment countries:
    • The river flows through Tibet, India (Arunachal Pradesh and Assam), and Bangladesh.
    • In Tibet, the river flows slowly with a wide, navigable channel for about 640 km.
    • Upon entering India through Arunachal Pradesh, it becomes the Dihang, and later merges with Lohit and Dibang rivers to be called the Brahmaputra.
    • In Bangladesh, it is called the Jamuna, which merges with the Ganga (Padma) and Meghna before flowing into the Bay of Bengal.
  • The world’s largest and smallest river islands, Majuli and Umananda, are located on the Brahmaputra in Assam.
  • Important Tributaries:
    • Left-bank tributaries: Lhasa, Nyang, Parlung Zangbo, Lohit, Dhanashri, Kolong
    • Right-bank tributaries: Kameng, Manas, Beki, Raidak, Jaldhaka, Teesta, Subansiri
  • States the River Flows Through in India: Arunachal Pradesh, Assam, Meghalaya, Nagaland, West Bengal, and Sikkim.
  • Major Cities on the River: Dibrugarh, Pasighat, Neamati, Tezpur, and Guwahati.
  • Major Hydel Projects:
    • Arunachal Pradesh: Subansiri, Kameng, Ranganadi, etc.
    • Assam: Kopili
    • Sikkim: Teesta, Rangit
    • Meghalaya, Nagaland, Manipur, Mizoram: Multiple local hydropower stations

The Crisis In The Middle East

Places in News: Zangezur Corridor

Why in the News?

The aftermath of Operation Sindoor highlights India’s strategic concerns over the proposed Zangezur Corridor in Armenia backed by Azerbaijan and Turkiye.

Zangezur Corridor

About the Zangezur Corridor:

  • What it is: The Zangezur Corridor is a proposed land route through Armenia’s Syunik Province that would connect Azerbaijan to its Nakhchivan region, cutting across Armenian land.
  • Who supports it: Azerbaijan and Turkiye back the project. They want a direct link without Armenian border checks or customs interference.
  • Route Details: The corridor would be about 43–44 km long and pass near the Iran-Armenia border, giving it high geopolitical value.
  • Why it’s controversial:
    • Azerbaijan sees it as a post-war right after its win in the 2020 Nagorno-Karabakh conflict.
    • Armenia insists it must have full control and sovereignty over any transport through its territory.
  • Turkiye’s Interest: It wants to use this corridor as part of its Middle Corridor project to connect with Central Asia and Europe via land routes.
  • Opposition: Iran and Armenia oppose the corridor, fearing it could:
    • Isolate Armenia,
    • Weaken Iranian access, and
    • Threaten Armenia’s territorial integrity.

How it concerns India?

  • Strategic Ties: India is a key defence partner for Armenia and supports regional stability in the South Caucasus.
  • Trade Ambitions: India is:
    • Developing Chabahar Port in Iran,
    • Working on a transport route via Iran–Armenia–Georgia to Europe, bypassing Pakistan and the Suez Canal.
  • Concerns: If the Zangezur Corridor bypasses Armenian control, it could:
    • Disrupt India’s land trade route to Europe,
    • Reduce Iran’s regional access,
    • Weaken India’s strategic reach.
  • Larger Geo-Politics: Turkiye and Azerbaijan’s growing influence in the region is worrying for India, especially since Turkiye opposes India’s IMEC (India-Middle East-Europe Corridor).
  • India’s Stand: India supports Armenia’s sovereignty and opposes unilateral moves, aiming to:
    • Protect its trade routes,
    • Preserve strategic balance, and
    • Counter regional encirclement.

Innovations in Sciences, IT, Computers, Robotics and Nanotechnology

JNCASR develops Fast-Charging Sodium-Ion Battery

Why in the News?

Scientists at Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), Bengaluru have developed a super-fast charging Sodium-ion battery.

About Sodium-Ion Battery and Its Working:

  • What it is: Sodium-ion batteries are rechargeable batteries that use sodium (Na) ions to carry electric charge, instead of lithium.
  • How it works: During charging and discharging, sodium ions move between the anode (negative) and cathode (positive) — similar to how lithium-ion batteries function.
  • Innovation: A sodium-ion battery developed by JNCASR uses NASICON-type chemistry, a special material structure that ensures fast ion movement and stability.
  • Performance Boost: The team used nano-particles, added a carbon coating, and used aluminium doping to improve charging speed and battery life.
  • Fast Charging & Long Life: The battery can charge up to 80% in 6 minutes and last over 3,000 charge-discharge cycles.
  • Tested for Safety: The battery passed tests using electrochemical cycling and quantum simulations, proving it is safe and durable.

Advantages over Lithium-Ion Batteries:

  • Sodium is abundant and cheaper than lithium, and it can be extracted from seawater.
  • Sodium-ion batteries are safer, as they can be transported at zero voltage and used in high temperatures without risk of fire.
  • They are more eco-friendly, with less environmental damage during extraction compared to lithium.
  • Material costs are lower because they use aluminium instead of copper.
  • India can reduce its dependence on China, which controls much of the lithium battery supply chain.
  • These batteries are ideal for renewable energy applications, such as solar grids, electric vehicles, drones, and rural electrification in extreme climates.
[UPSC 2025] In the context of electric vehicles, consider the following elements:

I. Cobalt II. Graphite III. Lithium IV. Nickel

How many of the above usually make up battery cathodes?

How is Economic Growth measured?

  • Gross Domestic Product (GDP) measures economic growth by adding all expenditures in the economy — including private, government, and business spending. It shows demand-side performance.
  • Gross Value Added (GVA) measures the supply-side. It calculates how much value is added by each sector of the economy.
  • GDP and GVA are related:
    GDP = GVA + (Taxes) – (Subsidies)
  • MoSPI reports both in:
    • Nominal terms: Includes current prices.
    • Real terms: Adjusted for inflation to reflect true growth.

Why are these Estimates called “Provisional”?

  • GDP estimates are revised in stages:
    • January: First Advance Estimates (FAE)
    • February: Second Advance Estimates (SAE)
    • May: Provisional Estimates (PE)
  • Final figures come later:

[30th May 2025] The Hindu Op-ed: Rewriting the script of Early Childhood Education

PYQ Relevance:

[UPSC 2020] National Education Policy 2020 is in conformity with the Sustainable Development Goal-4 (2030). It intends to restructure and reorient education system in India. Critically examine the statement.

Linkage: A key focus of the NEP 2020 is the strengthening and formalization of Early Childhood Care and Education (ECCE), recognizing its foundational importance. Therefore, critically examining the NEP 2020 directly relates to the concept of “rewriting the script” for education, including ECE.

 

Mentor’s Comment:  Lack of proper early childhood care and education (ECE) increases inequality, affecting children’s brain development, learning ability, and future income. Nobel Prize winner James Heckman’s research shows that investing in young children gives the best returns. This highlights the need for urgent systemic changes. Some states like Uttar Pradesh, Odisha, and Madhya Pradesh are already making progress with innovative ECE programmes. These small but focused steps in early childhood can help break the cycle of poverty and help India fully benefit from its young population by 2047.

Today’s editorial will talk about the early childhood care and education (ECE) . This content would help in GS Paper II ( Policy Making & Education).

Let’s learn!

Why in the News?

India’s silent but urgent employment crisis is rooted not just in the lack of jobs, but in the lottery of birth that disadvantages millions of children from the outset. So, smart spending on early childhood education and involving parents will support young children in learning better.

What is the lottery of birth? 

  • The “lottery of birth” refers to the idea that a child’s future is largely shaped by the circumstances into which they are born, such as: Family income, Geographic location, Caste, gender, or religion, Access to health, nutrition, and education.
  • These are factors beyond the child’s control but can determine their opportunities, development, and life outcomes.

What is the significance of the “lottery of birth” in shaping a child’s future in India? 

  • Determines Access to Basic Needs Early On: A child born into poverty often lacks access to adequate nutrition, healthcare, and early learning, which are essential for cognitive and physical development. Eg: A child born in a rural poor household may suffer from malnutrition and poor school readiness, limiting long-term potential.
  • Creates Early Learning and Earning Gaps: By age 5, differences in language, numeracy, and motivation are already visible, making it harder for disadvantaged children to catch up in school and later in life. Eg: Only 15% of pre-primary children could match basic objects, and 30% could identify larger and smaller numbers, indicating early learning gaps.
  • Perpetuates Intergenerational Poverty: Children born into poverty often remain trapped in low-opportunity environments, repeating the cycle into adulthood due to limited human capital development. Eg: Without quality early education, a poor child is far less likely to complete schooling or access skilled employment, thus continuing the poverty cycle.

Why is early childhood care and education (ECE) considered a high-return investment?

  • Highest Returns on Human Capital Investments: The Heckman Curve shows that investments in ECE yield the greatest returns compared to later stages of education or training. Eg: For every $1 spent on ECE, the return ranges between $7 to $12, through better education, health, and reduced crime.
  • Long-Term Economic and Social Benefits: Quality ECE leads to higher lifetime earnings, better employment, and improved life outcomes, helping individuals and economies thrive. Eg: Children with access to quality ECE are 4 times more likely to earn higher incomes and 3 times more likely to own a home as adults.
  • Bridges Early Learning Gaps and Boosts School Readiness: ECE helps close learning gaps caused by poverty, ensuring children enter school prepared, reducing dropouts and remedial education costs. Eg: States like Odisha are launching Shishu Vatikas to prepare 5–6-year-olds for formal schooling, improving readiness and future learning outcomes.

Who are the key stakeholders responsible for improving ECE outcomes in India?

  • Anganwadi workers and government pre-primary school teachers are frontline educators.
  • State governments are responsible for hiring dedicated ECE teachers and creating infrastructure.
  • Parents and caregivers play a crucial role in reinforcing learning at home.
  • Supervisors and training institutions ensure quality and pedagogy through monitoring and capacity building.
  • The Government of India provides funding and policy direction, though current spending is limited (₹1,263 per child annually).

Where are Indian states like Uttar Pradesh and Odisha making notable ECE interventions?

  • Uttar Pradesh: Hiring of ECE Educators and Teacher Training: Uttar Pradesh is recruiting nearly 11,000 Early Childhood Care and Education (ECE) educators for Balavatikas across districts. The state also held a six-day residential training for 50 master trainers from 13 districts to improve ECE pedagogy. Eg: These trained master trainers will cascade the training to other educators, ensuring quality instruction in early years.
  • Odisha: Launch of Shishu Vatikas and Jaduipedi Kits: Odisha is setting up Shishu Vatikas in all government schools to prepare children aged 5–6 for formal schooling. The state also introduced Jaduipedi Kitsplay-based learning materials to enhance school readiness. Eg: These initiatives are aligned with NEP 2020 and help improve early learning outcomes through structured activities.

How can parental involvement improve the effectiveness of early learning initiatives?

  • Strengthens Learning Continuity at Home: When parents engage in their child’s early education, it reinforces what is taught at ECE centres, ensuring consistent learning both at home and school. Eg: Providing simple worksheets or storybooks for home use helps children practice and retain concepts better.
  • Improves Child Motivation and Confidence: Active parental involvement boosts a child’s sense of security, motivation, and self-esteem, making them more eager to learn. Eg: In Madhya Pradesh, programmes like Bal Choupal involve parents in play-based activities, which positively impact children’s classroom participation.
  • Bridges Knowledge Gaps through Technology: Digital tools like WhatsApp groups or EdTech apps help parents access learning tips, track progress, and support their child’s development, especially where formal education resources are limited. Eg: Parents receiving weekly learning activities via smartphones are better equipped to support foundational skills like language and numeracy.

What are the steps taken by the Indian government?

  • Integration of ECE in National Education Policy (NEP) 2020: The NEP 2020 recognizes early childhood education as a critical foundation and proposes a new 5+3+3+4 curriculum structure, where the first five years focus on foundational learning (ages 3–8). Eg: Introduction of the “Foundational Literacy and Numeracy” mission (NIPUN Bharat) to ensure basic learning outcomes by Grade 3.
  • Expansion and Strengthening of Anganwadi Centres: The government has focused on upgrading 14 lakh Anganwadi centres across India to serve as key delivery points for ECE, nutrition, and health services. Eg: POSHAN Abhiyaan supports capacity-building of Anganwadi workers and provides teaching-learning material to improve preschool education quality.

Way forward: 

  • ​​Increase Investment and Improve Infrastructure in ECE: The government should significantly raise funding per child for early childhood education to ensure adequate instructional time, trained teachers, and quality learning materials. Strengthening infrastructure, including more Anganwadi centres and pre-primary schools with dedicated educators, will help bridge existing gaps and improve learning outcomes.
  • Enhance Parental Engagement and Community Participation: Empower parents with awareness, guidance, and digital tools to participate in their children’s early learning. Community-based programs like Bal Choupal should be expanded nationwide, and EdTech solutions leveraged to provide continuous support, creating a strong home-school learning ecosystem.

TR1 Cells: The Hidden Warriors in Malaria Immunity

Why in the News?

Scientists at Stanford University discovered that TR1 cells play a dominant role in fighting malaria reinfections.

Understanding the Body’s Immune Response:

  • What is the Immune System? It’s the body’s defence system that protects us from infections like malaria.
  • First Defence: The skin and body surfaces block germs from entering.
  • Innate Immunity: If germs get in, the innate immune system reacts fast, like an emergency response team.
  • Adaptive Immunity: Then, the adaptive immune system kicks in, targeting germs specifically and remembering them for future protection.
  • B-Cells and T-Cells:
    • B-cells make antibodies to fight germs.
    • T-cells attack infected cells and guide other immune cells.
  • Helper T-Cells: A type called CD4+ T-cells helps organise the defence. Earlier, scientists thought TH1 cells were key in malaria, but a new study shows TR1 cells are more important, especially in repeat infections.

What are TR1 Cells?

  • Role of TR1 Cells: These are special T-cells that help control the immune system and prevent overreaction.
  • Major Response in Malaria: Though small in number, during malaria, TR1 cells become the main helper cells.
  • Study in Uganda: In young children with repeated malaria, TR1 cells grew in number and improved the body’s ability to fight malaria without severe illness.
  • Memory and Immunity: TR1 cells remember the malaria parasite and return stronger with each infection.
  • Types of TR1 Cells:
    • Naïve TR1 – not yet active.
    • Effector TR1 – fighting infection.
    • Memory TR1 – remembering past infections.
  • Epigenetic Role: TR1 cells may respond by switching genes on or off, not by changing the genes themselves.

Key Findings of the Study:

  • Research Team: Scientists from Stanford University studied people in Uganda over many months and years.
  • Tracking Infections: They followed individuals through multiple malaria infections to see how immune cells behaved.
  • Gene Scanning: A special technique was used to read the genes of each immune cell — like scanning a barcode.
  • Findings: TR1 cells were accurate, long-lasting, and clearly connected to malaria (not other infections).
  • Why it matters: This discovery can help in making better malaria vaccines, boosting long-term protection, and even improving treatments for other serious diseases.
[UPSC 2025] With reference to monoclonal antibodies, consider the following:

I. They are man-made proteins. II. They stimulate the patient’s immune system to fight the specific disease. III. They are produced using animal cells only.

Which of the statements given above are correct?

Options: (a) I and II only (b) II and III only (c) I and III only (d) All the three *
