What are the key components of India’s energy strategy?
- Four-pronged approach: a) Diversification of energy sources and suppliers, b) Expansion of domestic production, c) Transition to renewables, d) Ensuring affordability for citizens
- Structural transformation: Significant reforms in both upstream and downstream sectors, including new revenue-sharing models, pricing reforms, and logistics integration.
- Digital mapping & infrastructure: PM Gati Shakti digitally mapped over 1 lakh energy assets, integrated with the National Master Plan for real-time visibility and route optimization.
|
Why is energy security considered equivalent to development security for India?
- Rapidly Growing Energy Demand: With India projected to account for 25% of global energy demand growth by 2047, uninterrupted energy supply is essential to fuel economic growth, industrial output, and urban development. Eg: India’s rise to the 4th-largest oil consumer shows its energy needs are deeply tied to its global economic standing.
- Foundation for Self-Reliance and Sovereignty: Ensuring access to affordable and sustainable energy strengthens national resilience and reduces geopolitical vulnerabilities. Eg: Ethanol blending (19.7% in 2025) and expanding biofuels have saved ₹1.26 lakh crore in foreign exchange, enhancing energy independence.
- Social Stability and Equitable Access: Affordable and stable energy supply supports welfare schemes and shields vulnerable populations from price shocks. Eg: Under PM Ujjwala Yojana, LPG cylinder prices for beneficiaries remain at ₹553 despite a global 58% rise, ensuring energy access for the poor.
How has India expanded its domestic oil and gas exploration acreage from 2021 to 2025?
- Doubling Exploration Acreage: India increased its exploration area from 8% in 2021 to 16% in 2025, aiming to cover 1 million sq km by 2030 to unlock vast hydrocarbon resources. Eg: This expansion includes frontier basins like the Andamans and the Mahanadi.
- Landmark Policy Reforms: Reforms such as reducing ‘No-Go’ zones by 99% and streamlining licensing through the Open Acreage Licensing Policy (OALP) rounds have facilitated easier access for exploration. Eg: The OALP rounds attract new investors by offering simplified licensing.
- Attractive Pricing and Revenue Sharing: New pricing mechanisms link gas prices to 10% of the Indian crude basket with a 20% premium for new wells, and revenue-sharing contracts allow shared infrastructure, boosting investment incentives. Eg: These incentives encourage development of new gas wells and city gas networks.
Which renewable energy initiatives have contributed significantly to India’s green energy transition?
- Ethanol Blending in Petrol: Ethanol blending increased from 1.5% in 2013 to 19.7% in 2025, expanding the ethanol supply from 38 crore litres to 484 crore litres, reducing emissions and saving foreign exchange. Eg: This has saved ₹1.26 lakh crore in foreign exchange and reduced 643 lakh MT of emissions.
- Compressed Biogas (CBG) through SATAT Initiative: The SATAT program has commissioned over 100 CBG plants and targets a 5% CBG blending mandate by 2028, promoting circular and affordable bioenergy. Eg: Central support for biomass procurement and CBG pipeline connectivity accelerates adoption.
- Green Hydrogen Production: India has produced 8.62 lakh tonnes of green hydrogen and awarded 3,000 MW electrolyser tenders, with public sector units leading large-scale hydrogen projects. Eg: Indian Oil Corporation’s 10 KTPA green hydrogen tender for the Panipat refinery.
What are the challenges?
- Infrastructure and Technology Gaps: Limited infrastructure for large-scale production, storage, and distribution of renewables like green hydrogen and biofuels slows down adoption. Eg: Need for expanded electrolyser manufacturing capacity to meet tender targets.
- Feedstock Availability and Supply Chain Issues: Securing consistent and diversified feedstock for biofuels like ethanol and CBG is challenging due to agricultural dependencies and regional disparities. Eg: Ensuring steady supply of molasses, maize, and biomass for ethanol and CBG production.
- High Initial Costs and Financing Constraints: Capital-intensive nature of renewable projects and lack of affordable financing options can hinder MSMEs and smaller players from scaling up. Eg: Limited access to credit for startups working on cutting-edge green hydrogen technologies.
Way forward:
- Boost Infrastructure and Technology: Invest in large-scale renewable production, storage, and distribution facilities—especially for green hydrogen and biofuels—and expand domestic manufacturing of key technologies like electrolysers.
- Enhance Feedstock Supply and Financing: Develop diversified, reliable feedstock supply chains for biofuels, and create affordable financing schemes to support MSMEs and startups in scaling clean energy innovations.

Why in the News?
India’s rooftop solar (RTS) capacity has gone beyond 17 GW, showing good progress in using clean energy in cities. But in crowded urban areas, there isn’t enough space for more rooftop solar panels.
What is Building-Integrated Photovoltaics (BIPV)?
BIPV refers to the integration of photovoltaic materials directly into the building envelope (e.g., façades, roofs, windows). It serves both as a building material and a solar power generator. Eg: Façades, curtain walls, glass windows, skylights, tiles, railings, balconies, canopies, atriums, and shading devices.
How does it differ from traditional rooftop solar systems?
|
Traditional Rooftop Solar (RTS) |
Building-Integrated Photovoltaics (BIPV) |
| Installation |
Added onto rooftops |
Embedded into building structure |
| Space Use |
Limited to rooftop area |
Uses entire building envelope (walls, windows etc.) |
| Aesthetic |
Usually visible, can affect aesthetics |
Customisable, aesthetically integrated |
| Function |
Only generates electricity |
Generates electricity + serves as a building material |
| Retrofitting |
Often retrofitted |
Typically integrated during design/build phase |
Why is BIPV particularly important for densely populated urban areas in India?
- Limited Rooftop Space in High-Rises: In densely populated cities, tall buildings with small rooftops cannot accommodate large rooftop solar (RTS) systems. Eg: A 16-storey building with a 4,000 sq. ft rooftop can install only a 40 kWp RTS system, but its south-facing façade can support 150 kWp BIPV panels.
- Efficient Use of Building Surfaces: BIPV allows power generation from vertical and horizontal surfaces like façades, windows, and balconies, thus using more surface area. Eg: Façade areas of buildings are often 3–4 times larger than rooftop areas, offering greater solar potential.
- Supports Sustainable Urban Growth: With India’s urban population projected to reach 850 million by 2051, BIPV enables renewable energy adoption in future infrastructure. Eg: Integration of BIPV in new public infrastructure (e.g., metro stations, airports) can reduce carbon footprint.
- Energy Access for Non-Rooftop Households: Residents in multi-storey apartments without rooftop access can still benefit from solar energy via BIPV on balconies, railings, or windows. Eg: In Germany, 15 lakh households use balcony solar panels, reducing electricity bills by up to 30%.
- Aesthetic and Space-Neutral Design: BIPVs blend into building designs without occupying extra space or affecting aesthetics, which is ideal for space-constrained urban settings. Eg: The Renewable Energy Museum in Kolkata has a solar-powered dome with over 2,000 integrated panels, combining function with form.
What challenges are limiting the adoption of BIPVs in India?
- High Initial Costs: BIPV systems are more expensive than traditional rooftop solar due to integration with building materials and use of advanced technology.
- Policy and Regulatory Gaps: Lack of clear policies, mandates, and incentives specific to BIPV hinders its integration into mainstream construction practices. Eg: Unlike Europe’s Energy Performance of Buildings Directive, India’s National Building Code does not yet mandate or promote BIPV use.
- Low Awareness and Technical Capacity: Architects, builders, and homeowners are often unaware of BIPV’s benefits or how to incorporate it effectively in design.
- Dependence on Imports and Limited Domestic Manufacturing: India relies heavily on imported BIPV components, increasing costs and reducing supply reliability. Eg: Specialised BIPV glass panels or semi-transparent modules are often imported from China or Europe due to lack of local alternatives.
- Absence of Standardisation and Performance Guidelines: There are no clear standards, benchmarks, or guidelines for BIPV performance, quality, and installation, causing hesitation among developers. Eg: Without defined safety and efficiency norms, urban local bodies may delay approvals or avoid BIPV in building plans.
What measures can India take to scale up the uptake of BIPVs effectively? (Way forward)
- Introduce Targeted Policy Incentives and Subsidies: India should extend solar subsidy schemes to specifically support BIPV adoption, especially in space-constrained urban areas. Eg: Under the PM Surya Ghar Muft Bijli Yojana (2024), BIPV was included with subsidies up to ₹78,000 for a 3-kW residential system. Similar support is needed for commercial and industrial sectors.
- Embed BIPV in Building and Energy Codes: Integrating BIPV requirements into the National Building Code, Energy Conservation Building Code, and Eco Niwas Samhita can make its use more widespread and standardized. Eg: Europe’s Energy Performance of Buildings Directive mandates solar use in new constructions and promotes BIPV with clear regulations—India can adopt a similar model.
- Promote Domestic Manufacturing and Demonstration Projects: Boosting indigenous production through PLI schemes, along with pilot projects in public infrastructure (e.g., schools, airports), can improve visibility and reduce costs. Eg: The CtrlS Datacenters in Navi Mumbai and Kolkata’s Renewable Energy Museum show how BIPV can be scaled in real-world infrastructure.
Mains PYQ:
[UPSC 2020] India has immense potential of solar energy though there are regional variations in its development. Elaborate.
Linkage: Building-Integrated Photovoltaics (BIPV) is a key solution for boosting solar adoption, especially in densely populated urban areas where traditional rooftop solar (RTS) is constrained by limited shadow-free space. BIPV transforms entire buildings into power generators by integrating solar elements directly into architectural elements, using available surfaces more efficiently and contributing significantly to India’s solar capacity goals.

Donald Trump’s push to return as U.S. President and his deal-based approach to security have led to doubts being raised about America’s strong support for global alliances like NATO and Indo-Pacific ties. As a result, a key chance is being presented to countries like India and Australia to take on a bigger role in regional security.
What opportunity does Trump’s return present for India-Australia defence ties?
- Strategic Autonomy Amid U.S. Uncertainty: Trump’s transactional approach and doubts over U.S. security guarantees create a power vacuum, pushing India and Australia to enhance self-reliant regional security frameworks. Eg: Trump’s past remarks questioning NATO and alliances signal that countries like India and Australia must prepare to collaborate independently in the Indo-Pacific.
- Convergence on Regional Threat Perception: Both nations share concerns about China’s assertiveness and have a common interest in upholding a rules-based Indo-Pacific order. Eg: Their cooperation in military exercises like Malabar and AUSINDEX reflects growing trust and joint readiness to ensure maritime security.
- Enhanced Role for Middle Powers: With the U.S. potentially pulling back, middle powers like India and Australia can take on more active roles in shaping the regional security architecture. Eg: The establishment of the Comprehensive Strategic Partnership (CSP) in 2020 and air-to-air refuelling arrangements show how both are stepping up bilateral defence engagement.
How have India and Australia enhanced their defence partnership?
- Strategic Frameworks and Dialogues: India and Australia have institutionalised their defence ties through frameworks like the Comprehensive Strategic Partnership (CSP) 2020 and the 2+2 Ministerial Dialogue (launched in 2021), enabling high-level strategic coordination. Eg: These platforms have strengthened regular engagement on defence, security, and regional stability.
- Operational Cooperation and Logistics Support: Practical collaboration has grown through agreements like the Mutual Logistics Support Agreement (MLSA), enabling joint exercises, logistics sharing, and humanitarian missions. Eg: In November 2024, an Air-to-Air Refuelling Agreement allowed the Royal Australian Air Force to extend the range of Indian fighter aircraft.
- Joint Military Exercises and Multilateral Engagement:The two countries regularly conduct tri-services and multilateral military exercises to build interoperability and trust. Eg: Exercises like AUSINDEX (Navy), AUSTRAHIND (Army), and participation in Malabar and Pitch Blackreflect deepening defence cooperation.
Why should India upgrade its Defence Adviser role in Canberra?
- Reflect Strategic Importance of the Partnership: Upgrading the DA role to a one-star rank signals that India values its growing defence relationship with Australia.
- Eg: Australia views India as a “top-tier security partner”; a higher-ranked DA would align with this perception and facilitate deeper military coordination.
- Ensure Balanced Tri-Service Representation: Currently held by a Navy officer, the DA position lacks dedicated Army and Air Force support, limiting joint-service engagement. Eg: Adding Army and Air Force assistants would enhance collaboration across all services, especially for tri-service exercises like AUSTRAHIND and AUSINDEX.
- Strengthen Pacific Island Outreach: The same DA currently manages India’s engagement with Pacific Island nations, which need focused strategic attention. Eg: Appointing dedicated personnel for Pacific outreach would align with India’s broader Indo-Pacific vision and regional diplomacy.
Which defence cooperation areas need urgent focus?
- Cross-Service Military Integration: Move beyond Navy-centric cooperation to promote joint operations across the Army, Navy, and Air Force. Eg: Plan a large-scale joint military exercise involving all three services to test real-world interoperability and enhance preparedness.
- Maintenance, Repair, and Overhaul (MRO) & Joint Manufacturing: Expand cooperation in naval MRO facilities and co-production of patrol boats for island nations. Eg: India’s MRO contracts with the U.S. and U.K. navies can be replicated with Australia to support regional maritime forces in the Indian and Pacific Oceans.
- Ground-Level Operational Exchanges and War-Gaming: Encourage working-level military exchanges, war-gaming, and fellowships to build trust and generate fresh strategic ideas. Eg: Regular staff college fellowships and classified tabletop exercises can deepen understanding and foster tactical collaboration.
|
How can MSMEs boost India-Australia defence collaboration?
- Promote Joint Innovation in Defence Tech: MSMEs and startups in both countries are at the forefront of dual-use and cutting-edge technologies. Collaborating can lead to co-development of defence innovations. Eg: Indian and Australian MSMEs can jointly develop components for drones, surveillance systems, or cyber-security tools.
- Align Indigenous Defence Programs: Both nations are running indigenisation drives in defence manufacturing. Aligning these efforts can reduce dependency on third-party suppliers. Eg: India and Australia can create a joint MSME supply chain for ship components or lightweight materials for aircraft.
- Create Bilateral Platforms for MSME Engagement: Establish frameworks similar to the U.S.-India INDUS X model to connect MSMEs, investors, and defence officials from both countries. Eg: A dedicated India-Australia Defence MSME Forum can organise hackathons, product expos, and joint funding opportunities.
Way forward:
- Deepen Tri-Service and Industrial Collaboration: Expand joint military exercises across all services and foster MSME-led co-development in defence tech, MRO, and manufacturing to build resilient, self-reliant capabilities.
- Strengthen Strategic Architecture and Representation: Upgrade India’s Defence Adviser role in Canberra and establish dedicated bilateral MSME engagement platforms to reflect the growing strategic importance and operational depth of the partnership.
Mains PYQ:
[UPSC 2021] The newly tri-nation partnership AUKUS is aimed at countering China’s ambitions in the Indo-Pacific region. Is it going to supersede the existing partnerships in the region? Discuss the strength and impact of AUKUS in the present scenario.
Linkage: Australia is undergoing a substantial overhaul of its armed forces and acquiring new technologies under AUKUS, which includes the U.S. and the U.K. This strategic shift for Australia, alongside concerns about “American security guarantees appear increasingly conditional,” creates a context where Australia’s defense ties with India, as a fellow middle power, are deepening. AUKUS, while involving the US, signifies a new alignment in the Indo-Pacific that impacts the broader strategic environment in which India and Australia forge their independent and collaborative defense relationship.

Researchers at the Indian Institute of Science (IISc) have created an artificial metal-based nanozyme that can help prevent dangerous blood clotting, especially in conditions like pulmonary thromboembolism (PTE) and COVID-19.
What is Blood Clotting?
- About: When we get a cut or injury, our body quickly stops the bleeding by forming a blood clot. This is done by special blood cells called platelets that stick together and seal the wound.
- Control mechanism: This natural process is called blood clotting or haemostasis and is controlled by certain chemicals in our body like collagen and thrombin.
- Post covid issues: But in some illnesses like pulmonary thromboembolism (PTE) or COVID-19, the body sends too many signals to make clots, even when there is no injury.
- Oxidative Stress: This creates a problem called oxidative stress, where harmful molecules called Reactive Oxygen Species (ROS) build up in the blood. These ROS molecules over-activate the platelets, causing them to make too many clots inside blood vessels.
- Hazards: This can block blood flow, leading to serious health issues like heart attacks, strokes, or lung problems. This condition is called thrombosis, and it can be life-threatening.
Vanadium-Based Nanozyme and Its Features:
- Purpose and Design: Scientists at IISc developed vanadium-based nanozymes to mimic natural antioxidant enzymes that reduce ROS levels.
- How they work: The nanozymes control oxidative stress by copying glutathione peroxidase, an enzyme that removes ROS and protects platelets.
- Optimal Structure: Spherical-shaped vanadium pentoxide (V₂O₅) nanozymes were found to be the most effective.
- Test Results in Mice: These nanozymes reduced blood clots and improved survival in PTE-affected mice with no toxicity signs over five days.
- Next Steps: Scientists plan to test the nanozyme in ischemic stroke and are optimistic about human clinical trials after promising lab results with human platelets.

The Indian government has proposed a phased winding down of the National Polio Surveillance Network (NPSN), a WHO-established network critical to tracking and eliminating polio in India.
About National Polio Surveillance Network (NPSN):
- Launch : The NPSN was established in 1997 as a collaboration between the World Health Organization (WHO) and the Ministry of Health and Family Welfare (MoHFW), Government of India.
- Objective: Its main goal is to detect and monitor the poliovirus in India to enable quick response and containment.
- Operational Structure: The network functions under the National Polio Surveillance Project (NPSP) and includes over 200 field surveillance units across the country.
- Methodology: The core method is Acute Flaccid Paralysis (AFP) surveillance, which tracks sudden paralysis in children under 15 — a key indicator of polio.
- Environmental Surveillance: The NPSN also tests sewage and water samples to detect silent circulation of the virus.
- Laboratory Support: A network of WHO-accredited laboratories confirms virus presence through testing of stool and water samples.
- Rapid Response: Every suspected case is quickly investigated, and public health teams are deployed for control and containment.
- Expanded Role: Over time, NPSN has also supported surveillance for measles, rubella, DPT, and helped train health workers on new vaccines.
Polio and Its Eradication in India:
- About: Polio is a highly infectious viral disease primarily affecting children under 5, potentially causing paralysis or death.
- Transmission: The disease spreads via the faecal-oral route, mostly through contaminated water or food.
- Types of Polioviruses:
- WPV1 still exists in Pakistan and Afghanistan.
- WPV2 and WPV3 have been eradicated globally.
- Infection Mechanism: Once inside the body, the virus multiplies in the intestines and may attack the nervous system, causing permanent paralysis.
- Prevention through Vaccination:
- Oral Polio Vaccine (OPV) is given at birth, 6, 10, and 14 weeks, with a booster at 16–24 months.
- Injectable Polio Vaccine (IPV) is administered with the third DPT dose under the Universal Immunization Programme (UIP).
- Pulse Polio Campaign (1995): India launched the Pulse Polio Immunization Campaign, providing oral polio drops to all children under 5.
- Eradication Milestones: The last wild polio case in India was reported in 2011, and in 2014, WHO officially declared India polio-free.
- Role of NPSN: The success was enabled by strong surveillance, mass immunization, and dedicated work by NPSN and its partners.

Researchers from the Vellore Institute of Technology (VIT) have discovered antibiotic-producing bacteria in the Rajgir hot spring in Nalanda, Bihar.
What are Thermophilic Bacteria?
- About: Thermophilic bacteria, or thermophiles (meaning “heat lovers”), are microorganisms that thrive in high-temperature environments ranging from 45°C to 70°C.
- Adaptation: These temperatures can cause third-degree burns in humans, but thermophiles are biologically adapted to survive and grow in such conditions.
- Habitats: They are commonly found in hot springs, deep-sea hydrothermal vents, and compost piles, which are mineral-rich and have low microbial competition.
- Advantages: Some thermophiles produce potent antibiotics to outcompete other microbes and dominate their niche.
- Global Example: Thermophiles from hot springs in Saudi Arabia have shown antibacterial activity against gram-positive pathogens.
Key Findings from India:
- Sampling Challenge: Samples were collected from water and soil at 43°C–45°C, making fieldwork difficult.
- Microbial Analysis: In the sample, Actinobacteria made up 40–43% of the microbial population, double the typical amount in hot springs.
- Significance: Actinobacteria are well known for producing key antibiotics like streptomycin and tetracycline.
- AMR Context: The findings are crucial in the fight against antimicrobial resistance (AMR), which could cost $1 trillion globally by 2050, according to the WHO.
- Antibiotic Potential:
- Lab Testing: Seven Actinobacteria strains were found to inhibit pathogens such as E. coli, Salmonella, Klebsiella, Pseudomonas, and Staphylococcus aureus.
- Compound Discovery: Scientists identified diethyl phthalate using GC-MS, which showed effectiveness against Listeria monocytogenes, a deadly foodborne pathogen.
- Future Scope: The compound has potential for antibiotic development, but not all thermophiles produce antibiotics, so screening is essential.
- Uses:
- Industrial Use: The enzyme Taq polymerase, used in PCR tests (including during COVID-19), is derived from a thermophile called Thermus aquaticus.
- Agricultural Use: A 2018 BHU study showed thermophiles from Chumathang hot springs (Leh) promote plant growth, revealing wider industrial and ecological value.

A high-powered committee chaired by Principal Scientific Advisor (PSA) Ajay Sood has proposed that India should discontinue the mandatory use of Flue Gas Desulphurisation (FGD) units in most coal-fired Thermal Power Plants (TPPs).
Why mandatory FGDs are opposed?
- Low SO₂ Levels: India’s SO₂ levels (10–20 µg/m³) are already below the permissible limit of 80 µg/m³.
- Low Sulphur Coal: Indian coal naturally has low sulphur content.
- Minimal Impact: Studies show no major air quality difference between plants with and without FGDs.
- Limited PM Reduction: FGDs have minimal effect on particulate matter levels.
- Environmental Trade-Offs:
- CO₂ Increase: Installing FGDs would add 69 million tonnes of CO₂ emissions (2025–2030).
- SO₂ Reduction: Emissions would fall by 17 million tonnes, but the climate cost outweighs the benefit.

About Flue Gas Desulphurisation (FGD):
- Purpose: FGD is a technology used to remove sulphur dioxide (SO₂) from flue gases produced by burning coal and oil, especially in thermal power plants.
- Environmental Benefit: It helps prevent acid rain, which harms crops, buildings, soils, and aquatic ecosystems.
- Chemicals Used: Common absorbents include limestone (CaCO₃), lime (CaO), and ammonia (NH₃).
- Types of Systems:
-
- Dry Sorbent Injection: Cost-effective, but less efficient.
- Wet Limestone-Based: Effective and used in large plants, produces gypsum.
- Seawater-Based: Uses alkaline seawater, ideal for coastal areas.
FGD Mandate in India:
- Current Status: FGD units are being installed in 537 coal-based thermal power units, but 92% of India’s 600 plants still lack them.
- Committee Recommendation: An expert panel advised exempting 80% of plants from FGD requirements due to feasibility issues.
- Implementation Barriers: Limited vendors available; High costs and risk of increased electricity tariffs.

On June 5, World Environment Day, Prime Minister Narendra Modi is expected to launch the Aravalli Green Wall Project.
About the Aravallis:
- Geology: The Aravalli Range is one of the oldest fold mountain ranges in the world, formed during the Proterozoic era.
- Spread: It stretches for about 692 km, from Gujarat to Delhi, passing through Rajasthan and Haryana.
- State-Wise Coverage: Around 80% of the range lies in Rajasthan, with the rest spread across Haryana, Delhi, and Gujarat.
- Highest Peak: The tallest point is Guru Shikhar in Mount Abu, Rajasthan, with an elevation of 1,722 meters.
- Natural Barrier Function: Acts as a green wall, preventing the spread of the Thar Desert into eastern Rajasthan and the Gangetic plains.
- River Origins: Important rivers such as the Banas, Sahibi and Luni originate from the Aravallis.
- Minerals: Rich in minerals like copper, zinc, lead, and marble.
- Biodiversity: Home to 300+ bird species and key wildlife such as leopards, hyenas, jackals, wolves, civets, and Nilgai.
- Prehistoric Significance: Contains cave art and tools from the Lower Palaeolithic period.

What is the Aravalli Green Wall Project?
- Project Goal: To build a green corridor from Delhi to Gujarat combating desertification and ecological degradation.
- States Involved: Includes Delhi, Rajasthan, Haryana, and Gujarat, focusing on restoring degraded landscapes.
- Vegetation Strategy: Focus on removing Prosopis juliflora (invasive species) and planting native trees like:
- Khair (Indian Gum Arabic)
- Ronjh (White-barked Acacia)
- Dhau (Axlewood)
- Salai (Indian Frankincense)
- Pilkhan, Neem, Amaltas, Goolar, Peepal
- Buffer Zone Creation: A 6.45 million hectare buffer zone will be established around the Aravallis.
