Bridging the Propulsion Gap
Category: SCIENCE AND TECHNOLOGY
Context: India remains heavily reliant on imported aircraft engines, affecting its defence capabilities and strategic autonomy
Decoding Context:
Key Developments:
HF-24 Marut:
India’s first indigenous fighter jet, developed in the 1950s-70s, underperformed due to lack of a powerful indigenous engine, relying instead on imported engines.
Kaveri Engine Project:
Launched in 1986 for the LCA Tejas, it failed to meet requirements even after decades of development and ₹2,000 crore in spending.
Why It Matters:
Engine Dependency:
Recent disruptions (e.g., GE F404 engine delivery delays from the U.S.) highlight how foreign engine delays hinder military programs like the LCA Mk1A.
Import Bottlenecks:
India depends on imported engines for air, sea, and land systems—impacting tanks, submarines, aircraft, and ships. This creates strategic vulnerability.
Impact on Future Projects:
India’s 5th-gen AMCA and other defence programs risk delays unless engine self-sufficiency is prioritized.
Strategic Importance:
Indigenous propulsion tech is crucial for:
Sustained military readiness.
Reducing foreign dependency.
Withstanding geopolitical shocks.
It’s not just a technical issue but a national security imperative.

Arak Heavy Water Reactor
Category: SCIENCE AND TECHNOLOGY
Context : Israël strike-hit Arak heavy water reactor was part of Tehran’s nuclear deal.
About Arak Heavy Water Reactor
Located ~250 km southwest of Tehran, the Arak reactor has long been a global concern due to its capacity for producing weapons-grade plutonium.
Originally designed to generate ~9 kg of plutonium per year—enough for one nuclear bomb annually.
Role in the 2015 JCPOA (Iran Nuclear Deal)
Iran agreed to redesign the Arak reactor to prevent plutonium production.
The original core was disabled and filled with cement.
The International Atomic Energy Agency (IAEA) verified the reactor was made inoperable and monitored modifications.
Recent Developments (2025)
June 19, 2025: Israeli airstrike damaged the reactor’s core seal and its heavy water production plant, aiming to prevent future weaponization.
The reactor was not yet fueled, and the IAEA confirmed no radioactive risk.
Concerns remain that Iran has not fully completed the redesign, with construction reportedly continuing and possible operation by 2026.

Revised Green India Mission (GS Paper III – Environment)
Introduction (Context)
Recently, the government has released a revised roadmap for the National Mission for Green India, also known as the Green India Mission (GIM). In addition to the core objectives of increasing and restoring forest and green cover, the mission will focus on restoration in the Aravalli ranges, Western Ghats, Himalayas and mangroves.
What is Green India Mission (GIM)?
GIM was launched in 2014 and is one of the eight missions under the National Action Plan on Climate Change (NAPCC).
It is implemented by the Ministry of Environment, Forest and Climate Change (MoEFCC).
Its core aim is to combat climate change by increasing forest and tree cover, and the ecological restoration of degraded ecosystems and forests.
It also aims to improve the livelihoods of communities dependent on forest produce.
Its objective was to increase forest and tree cover on 5 million hectares and improve the quality of forest cover on another 5 million hectares.
Why was the Green India Mission implemented?
India’s forests have faced degradation due to deforestation, encroachment, and unsustainable use.
Forests are crucial for carbon sequestration, maintaining ecological balance, and supporting biodiversity.
The mission supports India’s commitment to create a carbon sink of 2.5–3 billion tonnes of CO₂ and restore 26 million hectares of degraded land by 2030 under international climate agreements.
It aligns with the global goals under the Paris Agreement and UNCCD Bonn Challenge.
Status of Green Cover in India
The total forest and tree cover in India is about 24.62% of the country’s geographical area.
There has been an increase of 2,261 sq. km in forest and tree cover since the previous assessment.
Forest-rich states include Madhya Pradesh, Arunachal Pradesh, and Chhattisgarh in terms of area, and Mizoram, Arunachal Pradesh, and Meghalaya in terms of percentage coverage.
However, challenges like fragmentation, encroachment, and forest fires continue to threaten forest ecosystems.
Achievements of Green India Mission So Far
Between 2015–16 and 2020–21, plantation and afforestation activities were carried out over 11.22 million hectares through various schemes.
From 2019–20 to 2023–24, the Centre released ₹624.71 crore to 18 states, of which ₹575.55 crore has been utilized.
Activities under GIM are concentrated in states based on mapping of ecological vulnerability, potential for sequestration (the process by which plants and trees store carbon using photosynthesis), forest and land degradation, and restoration potential.
Revised Roadmap of GIM
The mission is now more focused on landscape-level restoration using region-specific best practices.
A saturation approach will be adopted to restore vulnerable and degraded landscapes thoroughly.
Area and landscape-specific restoration activities will occur mainly in three important mountain ranges – the Aravallis, the Western Ghats, and the Indian Himalayas, along with the mangrove ecosystems.
Key interventions:
GIM interventions will be synced with the Centre’s recently launched Aravalli Green Wall project, aimed at combating the degradation and desertification in one of the world’s oldest mountain ranges, which acts as a natural barrier against the Thar desert.
In the Aravalli region, restoration will cover 8 lakh hectares across 29 districts in 4 states. Native species will be planted to combat desertification and dust pollution. The estimated cost is ₹16,053 crore.
In the Western Ghats, the mission will focus on afforestation, eco-restoration of abandoned mines, and groundwater recharge to address deforestation and illegal mining.
In the Himalayas and mangrove areas, restoration will aim to strengthen natural buffers against climate impacts and enhance biodiversity.
India’s commitments for environment and how GIM will GIM Combat Land Degradation and Desertification?
According to the Indian Space Research Organisation’s Desertification and Land Degradation Atlas around a third of India’s geographical area 97.85 million hectares underwent land degradation during 2018-19.
According to its national commitments to tackle climate change submitted to the United Nations Framework Convention on Climate Change India aims to create an additional carbon sink of 2.5 to 3 billion tonnes of carbon dioxide through additional forest and tree cover by 2030,. The natural carbon sinks of forests, restored grasslands, wetlands, and mountain ecology will help offset greenhouse gas emissions and act as natural sponges and barriers in absorbing climate change impacts.
India has also made an ambitious commitment to restore 26 million hectares of degraded land by 2030.
Hence,
The mission will restore open forests, grasslands, wetlands, and catchment areas to enhance ecosystem services.
These natural ecosystems will act as carbon sinks, absorbing greenhouse gases and helping adapt to climate impacts.
The revised GIM aims to sequester 1.89 billion tonnes of CO₂ by restoring open forests over 15 million hectares.
GIM can help India expand its forest and tree cover up to 24.7 million hectares. This would be enough to achieve a carbon sink of 3.39 billion tonnes of CO2 equivalent by 2030, as per the FSI’s projections.
Value addition: Government Initiatives Supporting Green Cover Enhancement
Aravalli Green Wall Project: Aims to develop a 5 km wide green belt along the Aravalli hills to act as a barrier against desertification and reduce dust pollution in northern India.
National Afforestation Programme (NAP): Promotes reforestation and eco-restoration of degraded forest lands through community participation and joint forest management committees.
CAMPA Funds: Utilised for compensatory afforestation and regeneration activities when forest land is diverted for non-forest purposes like infrastructure or mining.
Urban Forest Scheme: Encourages the creation of dense, mini-forests in urban areas using native species to enhance green cover and urban biodiversity.
School Nursery Yojana: Engages school students in growing and nurturing tree saplings, promoting environmental education and awareness at a young age.
Van Dhan Yojana: Supports tribal livelihoods by enabling value addition and sustainable marketing of minor forest produce collected by forest-dwelling communities.
Conclusion
The revised Green India Mission represents a shift towards ecological, region-specific, and community-based forest restoration.
It aligns with India’s climate goals, biodiversity targets, and land restoration pledges.
Successful implementation can strengthen carbon sinks, enhance climate resilience, and promote sustainable livelihoods.

Critical Minerals important for India’s growth (GS Paper I – Geography, GS Paper III – Economy)
Introduction (Context)
The 21st century is witnessing a fundamental shift in global resource geopolitics from fossil fuels to critical minerals. As the world moves toward a cleaner, digital, and technologically advanced future, the demand for minerals like lithium, cobalt, nickel, and rare earth elements has surged. Hence, India must explore within as iIt is near-impossible to secure mineral supply chains from overseas.
What are Critical Minerals?
Critical minerals are metallic or non-metallic elements that are essential for high-tech, clean energy, defence, and economic applications but have high supply chain risks due to limited global sources or monopoly control.
Examples include lithium, cobalt, nickel, copper, rare earth elements, graphite, etc.
Usage of Critical Minerals
Critical minerals are essential components of various clean energy technologies and industries. Their importance can be highlighted across different sectors:
Solar energy
Critical minerals such as silicon, tellurium, indium, and gallium are vital for the production of photovoltaic (PV) cells used in solar panels.
India’s current solar capacity of 64 GW is heavily dependent on these minerals.
Wind energy
Rare earth elements like dysprosium and neodymium are used in permanent magnets for wind turbines.
India aims to increase its wind energy capacity from 42 GW to 140 GW by 2030, necessitating a stable supply of these minerals.
Electric vehicles (EVs)
Lithium, nickel, and cobalt are key materials used in lithium-ion batteries.
Under the National Electric Mobility Mission Plan (NEMMP), India plans to deploy 6–7 million EVs by 2024, leading to increased demand for these critical minerals.
Energy storage
Lithium-ion batteries used in advanced energy storage systems depend on lithium, cobalt, and nickel.
Global Status of Critical Mineral Supply Chains
Cobalt: Around 70% of global supply comes from the Democratic Republic of Congo (DRC).
Nickel: Indonesia accounts for nearly 50% of global production.
Lithium: Dominated by Australia, Chile, and China.
Rare Earth Elements: China alone contributes over 66% of global mining output.
Processing Monopoly:
China processes more than 66% of the world’s critical minerals, including copper and aluminium.
In the case of rare earth elements, China’s share exceeds 90%, giving it a near-monopoly on global supply chains.
China’s control over critical minerals gives it geopolitical and geoeconomic influence, as seen in trade disputes and restrictions on rare earth exports.
The US and EU have recognised this threat and are racing to diversify and secure their mineral sources.
Status of Critical Minerals in India
India is geologically rich but remains under-explored for critical minerals.
India currently imports most of its lithium, cobalt, and rare earths, making it vulnerable to supply disruptions.
As per the Indian Bureau of Mines India has potential reserves of rare earth elements in states like Andhra Pradesh, Odisha, and Kerala Khanij Bidesh India Ltd. (KABIL) has been set up to secure supply from overseas (e.g. lithium in Argentina, cobalt in Africa).
Despite this, domestic exploration is inadequate, and India lacks processing infrastructure.
Critical Minerals and Geopolitics
Minerals have also taken centre-stage in the global trade war. China is using its disproportionate control over rare earth materials to threaten the US and the rest of the world with the debilitating consequences of restricted supply.
US Policy Response:
US want to “annex” Canada and Greenland to have control over their vast mineral wealth.
US wants to solve Russia-Ukraine conflict is the potential for the US to access Ukraine’s rich mineral resources.
US is opening up vast tracts of federal land — previously on no-go lists — for mineral exploration on a fast-track basis, cutting approvals time from a year to less than a month.
India’s Lag:
Long clearance timelines.
Limited exploration and survey efforts.
Absence of commercial-scale refining or recycling infrastructure.
Value addition: National Critical Mineral Mission of India
The Government of India launched the National Critical Mineral Mission (NCMM) in 2025 to ensure long-term self-reliance in critical minerals essential for clean energy, technology, and national security.
Under NCMM, the Geological Survey of India (GSI) will conduct 1,200 exploration projects between 2024–25 and 2030–31.
A list of 30 critical minerals was identified by a Ministry of Mines committee in 2022; 24 of these are now under Central Government auction authority via the MMDR Act, 1957.
The mission aims to secure critical mineral availability, both domestically and from international sources, and establish a Centre of Excellence on Critical Minerals for strategic planning.
Objectives of NCMM
Secure domestic and global sourcing of critical minerals.
Strengthen the value chain through innovation, processing capacity, skill development, and recycling.
Reduce import dependency and enhance India’s role in the global clean-tech supply chain.
India’s Exploration Efforts
GSI has taken up 195 projects in 2024–25, including 35 in Rajasthan, focused on assessing domestic reserves.
Over 100 blocks of critical minerals are ready for auction.
Offshore exploration will target polymetallic nodules rich in cobalt, REEs, nickel, and manganese.
Exploration follows UNFC classification and MEMC Rules, 2015.
GSI previously identified rare earth elements in Rajasthan; the Department of Atomic Energy reported 1.11 lakh tonnes of REO reserves in Balotra.
Way Forward for India
Accelerate Exploration: Conduct modern, satellite-based mineral surveys to map reserves.
Policy Reforms: Fast-track mining leases, reduce approval time, and ensure ease of doing business in the mining sector.
Domestic Processing: Set up mineral processing and refining facilities through public-private partnerships.
Strategic Reserves: Create a stockpile of critical minerals similar to strategic oil reserves.
Global Collaboration: Expand partnerships under platforms like Quad, India-Australia-Japan supply chain initiative, etc.
Research & Recycling: Invest in urban mining and battery recycling technologies to reduce import dependence.
