The Maharashtra government recently scrapped its Government Resolutions (GRs) that mandated Hindi as a compulsory third language from Grades 1 to 5 in Marathi and English medium schools. While the decision was in line with the National Education Policy (NEP), 2020, which promotes multilingualism and a three-language formula, it was withdrawn due to concerns over linguistic identity, cultural hegemony, and the feasibility of implementing such a policy.
In response to this, the Maharashtra government has appointed a committee under Dr. Narendra Jadhav, a renowned economist, to study the three-language policy further.
Early Exposure vs. Formal Instruction: Research indicates that neuroscientific evidence supports early exposure to multiple languages, particularly between the ages of 2–8. However, formal classroom instruction in multiple languages from the start may weaken foundational literacy in a child's mother tongue (R1).
Cognitive Overload: Introducing three languages in the early years could lead to academic stress and diminished language skills, as students may struggle to develop proficiency in their primary language before tackling additional languages.
Centralization vs. Federalism: The three-language policy mandates Hindi as a compulsory language in non-Hindi-speaking states, which many states, like Tamil Nadu, see as an imposition on their regional languages. This policy was rejected in Tamil Nadu in 1968 and again in 2019, when the state succeeded in having Hindi removed from the draft NEP 2020.
States' Rights: Critics argue that enforcing Hindi without proper consultation with state governments undermines the federal spirit and regional autonomy. This has led to linguistic tensions, especially in states with a strong linguistic identity.
Threat to Regional Languages: Civil society groups fear that mandatory Hindi will lead to the marginalization of local languages, especially tribal and minority languages. These concerns also extend to the potential erosion of cultural identity.
Imposition of Hindi: Critics argue that mandating Hindi could be seen as a backdoor imposition, leading to cultural hegemony and a centralized cultural model that sidelines regional diversity.
Teacher Shortage: Many rural schools face a shortage of qualified teachers proficient in three languages, leading to uneven quality in instruction.
Curriculum Overload: Designing age-appropriate, integrated curricula that cover three languages at the primary level could lead to rote learning and reduced comprehension. The workload on students and teachers could escalate significantly.
The NEP 2020 emphasizes that mother tongue, local, or regional languages should be the medium of instruction up to Grade 5, ideally until Grade 8 and beyond. This approach aims to strengthen the child's foundation in their native language, which is crucial for cognitive development.
Unlike the previous NEP (1968), which mandated the study of Hindi, English, and a modern Indian language, the NEP 2020 offers greater flexibility:
No language will be imposed on any state.
States can choose to include classical languages (like Tamil, Telugu, Kannada, Malayalam) as part of the three-language formula.
Foreign languages such as German, French, or Japanese are also introduced as optional choices at the secondary level.
NEP 2020 highlights the importance of bilingual teaching, where children learn their mother tongue alongside English, ensuring they are comfortable in both local and global contexts.
Article 29: Protects the right of citizens to preserve their distinct language and culture.
Article 343: Declares Hindi as the official language of the Union, but allows continued use of English for official purposes.
Article 350A: Directs states to provide primary education in the mother tongue for linguistic minority children.
Article 350B: Provides for a Special Officer for linguistic minorities to ensure safeguards for their languages.
The Eighth Schedule lists 22 officially recognized languages, highlighting India’s diverse linguistic heritage.
Promotes Multilingualism and Cognitive Development
Learning multiple languages enhances memory, problem-solving, and academic performance.
Children can develop flexible thinking and appreciate diverse perspectives.
Supports National Integration
The policy encourages cross-linguistic communication, fostering a sense of unity across India's diverse linguistic groups.
Promotes respect and understanding of India's cultural diversity.
Improved Job Prospects
Proficiency in multiple languages opens up job opportunities in fields like tourism, media, and international relations.
Multilingual skills can improve employability in an increasingly globalized world.
Political Sensitivities
In states like Tamil Nadu, the policy is seen as imposing Hindi, a language often associated with majoritarianism and cultural dominance. This fuels regional identity politics.
Burden on Students and Schools
Overloading students with three languages at the primary level may stress their cognitive abilities.
Children from monolingual homes may struggle, leading to academic stress.
Implementation Challenges
The policy has faced failures in some regions, such as attempts to introduce Tamil in Haryana. These efforts were poorly planned and lacked demand or preparedness, highlighting the difficulty in nationwide implementation.
Institutional Preparedness
Prioritize foundational literacy and quality teaching rather than simply adding more languages.
Ensure qualified teachers and appropriate resources are available in schools to support multilingual education.
Balanced Multilingualism
The policy should respect regional language needs. In non-Hindi states, Hindi should not be forced, and states should be allowed to promote their regional languages alongside Hindi and English.
Reciprocal language learning should be encouraged, where students from North India learn Dravidian or tribal languages.
Language as a Tool of Social Justice
The policy should be designed to empower students, not to be a tool for political contestation.
Equity should be prioritized, ensuring that every language, whether regional, tribal, or foreign, is treated as an asset, not a barrier.
Linking Language Learning to Skills and Employability
Language education should not only focus on linguistic skills but also link language proficiency to vocational and digital skills to enhance employability, especially in fields requiring national mobility.
While the three-language policy can offer numerous benefits, including national integration and multilingualism, it must be implemented with caution and consideration for regional languages, cultural identities, and local needs. India’s rich linguistic diversity requires an inclusive approach that recognizes the importance of regional autonomy, mother tongue education, and educational infrastructure.
The Delhi government's focus on cleaning up the Yamuna River is part of a larger national effort to rejuvenate the Ganga River and its tributaries, in alignment with the Namami Gange Programme (NGP).
The pollution of India’s rivers is driven by a variety of factors that include industrial activities, agricultural runoff, cultural practices, and climate change.
Industries such as textiles, tanneries, and chemical plants discharge toxic effluents like lead, mercury, arsenic, and other heavy metals into rivers. Prominent examples include Kanpur's Ganga, Delhi's Yamuna, and Jharkhand's Damodar rivers.
Many industries bypass or misuse Effluent Treatment Plants (ETPs), diluting waste to meet regulatory standards and allowing harmful pollutants to enter rivers.
Fertilizers and pesticides from farming contribute to the growth of algal blooms, which harm aquatic life. Rivers like the Sutlej in Punjab are affected by nitrate and phosphate pollution.
Stubble burning in Punjab and Haryana adds ash to rivers via runoff, further degrading water quality.
Practices like idol immersion, cremation rituals, and the disposal of floral offerings pollute rivers. These include harmful substances such as Plaster-of-Paris, toxic paints, and plastic materials, especially in ghats like Varanasi's Ganga.
India is the world’s largest plastic emitter, with significant amounts of plastic waste entering rivers like Mumbai's Mithi River. Waste dumping from landfills, like Delhi’s Ghazipur, pollutes both groundwater and nearby rivers.
Thermal plants (e.g., Farakka, NTPC) discharge hot water into rivers, disrupting aquatic ecosystems.
Uranium mining in Jaduguda (Jharkhand) releases radioactive waste, which contaminates nearby rivers and harms aquatic biodiversity.
Erratic rainfall, low-flow periods, and extreme weather events concentrate pollutants in rivers. These conditions lead to more contaminants being flushed into rivers during heavy rains.
The Namami Gange Programme is an ambitious national initiative launched by the Ministry of Jal Shakti to rejuvenate the Ganga River and its tributaries, including the Yamuna. The program focuses on cleaning the rivers, improving water quality, and restoring their ecological health. Its major objectives include pollution abatement, wastewater treatment, afforestation, and the development of riverfronts.
Sewerage Treatment Infrastructure: Focused on constructing Sewage Treatment Plants (STPs) to manage wastewater and reduce river pollution.
River-Surface Cleaning: Efforts to remove solid waste and pollutants from the river's surface.
Afforestation: Planting trees and restoring green cover along riverbanks.
Industrial Effluent Monitoring: Enforcing regulations on industrial effluents to protect rivers from toxic discharges.
River-Front Development: Creating public spaces along the river to engage local communities and promote eco-tourism.

Strengthening People-River Connect (Jan Ganga): Promoting community participation and involving local stakeholders in conservation efforts.
Facilitating Research and Policy (Gyan Ganga): Encouraging scientific research and supporting evidence-based policies for river management.
Pollution Abatement: The sewage treatment capacity has surpassed pre-2014 levels by over 30 times.
Water Quality Improvement: Significant improvements in water quality, as seen in the Ganga's Biochemical Oxygen Demand (BOD) levels:
Uttar Pradesh: BOD reduced from 10-20 mg/l in 2015 to 3-6 mg/l in 2022.
Bihar: BOD reduced from 20-30 mg/l in 2015 to 6-10 mg/l in 2022.
BOD is a critical indicator of water quality. Lower BOD means cleaner water, as it reflects less organic pollution.
Biodiversity: The population of the Gangetic River Dolphin has increased, with sightings reported in areas like Bithura to Rasula Ghat and the Babai and Bagmati rivers.
Global Recognition: The UN’s Decade on Ecosystem Restoration (2021-2030) recognized the NGP as one of the Top 10 World Restoration Flagship Initiatives in 2022.
Implement Zero Liquid Discharge (ZLD) for industries, ensuring that no untreated water is released into rivers.
Strengthen the enforcement of Effluent Treatment Plants (ETPs) with real-time monitoring to ensure compliance.
Imposing strict penalties on industries involved in illegal dumping and pollution.
Encourage organic farming and sustainable practices that reduce chemical use and prevent runoff.
Establish vegetative buffer zones along rivers to filter pollutants before they reach water bodies.
Provide eco-friendly subsidies and incentives for farmers to adopt green practices.
Strengthen waste collection, segregation, and scientific disposal practices.
Prevent riverbank dumping by constructing fencing and deploying patrolling systems.
Implement a ban on single-use plastics and enforce it rigorously.
Conduct desilting operations to restore natural water flow.

The Namami Gange Programme serves as a comprehensive model for river rejuvenation and pollution control, with the Yamuna clean-up aligning with national goals. However, India's river pollution crisis demands a multi-faceted approach—combining industrial regulation, sustainable agriculture, solid waste management, and ecosystem restoration.
The recent collapse of the Mahisagar River Bridge in Vadodara, which tragically claimed the lives of 20 people, underscores the growing concern over India's infrastructure quality.
Gujarat (2022): The Morbi suspension bridge collapse, which killed 135 people, drew national attention to the state of infrastructure. The bridge, poorly maintained and insufficiently checked, fell into disrepair before the tragedy.
Maharashtra: The Palava Bridge on the Kalyan-Shil Road had to be shut down just two hours after it opened, due to structural defects. Similarly, the Pune Pedestrian Bridge over the Indrayani River collapsed under the weight of tourists.
Assam (June 2025): Harang Bridge collapsed when overloaded trucks crossed during heavy rain, cutting off Barak Valley from Tripura, Mizoram, and Manipur.
Madhya Pradesh: The Aishbagh rail overbridge in Bhopal, which had an unsafe 90-degree turn, faced public outrage for posing a serious hazard.
Bihar (2024): The state saw at least 12 bridges collapse in 20 days. The Bichli Pul collapse over the Gandak River in 2025 isolated 80,000 residents.
These incidents show a disturbing trend of poor quality and lack of maintenance in critical infrastructure across India.
Contractor mafias and kickbacks often lead to the use of cheap, poor-quality materials in major infrastructure projects, all for higher profit margins.
Ghost projects, especially in states like Bihar, see funds misused or diverted, resulting in unsafe and incomplete structures. For example, in Purnea, a bridge was built illegally as part of a land scam.
Old bridges, such as those in Morbi and over the Indrayani River, suffer from neglect. There is often no inspection or reinforcement to maintain their integrity.
Overloading, as witnessed in Assam’s Harang Bridge, occurs when heavy vehicles are allowed to cross unchecked, leading to structural collapse.
Poor planning and unsafe design choices, such as the Aishbagh rail overbridge in Bhopal, result in hazardous infrastructure.
Lack of oversight and technical review in the planning and execution phases contribute to flaws in bridge construction.
Failure to hold contractors and officials accountable after major disasters, like the Morbi collapse, ensures that such incidents are often repeated. Without strong accountability, unsafe infrastructure continues to be a problem.
In states like Assam and Bihar, floods and river erosion weaken bridge foundations, and there is often little preventive action taken to strengthen infrastructure in flood-prone areas.
Rushed inaugurations (such as the Palava Bridge) often happen when projects are not completed or fully tested, putting public safety at risk. Political interference leads to compromised construction standards and bypassing necessary safety checks.
India boasts the world’s second-largest road network, with National Highways extending to 1,46,145 km as of 2024. This is a significant achievement, given the country's vast geography and population.
India’s first bullet train project, aimed to run at 280 km/h, is expected to be completed by 2026. The railways have also seen a reduction in major accidents over the last decade.
India is now the third-largest domestic aviation market in the world. The number of operational airports has increased from 74 in 2014 to 157 by 2024, and millions of passengers have benefited from the UDAN scheme.
India is working to become one of the top five shipbuilding nations by 2047. Major projects like the Galathea Bay mega port and the India-Middle East-Europe Economic Corridor are underway.
The metro network has grown from 248 km in 2014 to 945 km in 2024, connecting 21 cities and serving over 1 crore daily commuters. Notable projects, such as the Namo Bharat train on the Delhi-Meerut RRTS, strengthen regional connectivity.

National Infrastructure Pipeline (NIP): Aims to develop infrastructure across the country.
Sagarmala Project: Focuses on improving port connectivity and maritime infrastructure.
Ude Desh Ka Aam Nagrik (UDAN): Promotes regional air connectivity, making air travel affordable for the masses.
Independent audits should be mandatory for major infrastructure projects, particularly bridges and highways. Institutions like IITs could carry out these audits, ensuring that poor construction practices are identified before completion.
Blockchain technology can be adopted to track funds in real time, preventing corruption and embezzlement.
The use of high-quality materials, like fiber-reinforced polymers and corrosion-resistant alloys, should be prioritized, especially in flood-prone areas like Assam and Bihar.
AI and IoT-based sensors can be deployed for real-time monitoring of bridge health, detecting cracks, overloading, and stress before structural failures occur.
Proactive maintenance should be prioritized, with a fixed percentage of capital expenditure allocated specifically for Operations and Maintenance (O&M).
States should implement structured maintenance policies like Bihar’s Bridge Maintenance Policy 2025, which mandates IIT audits and sensor-based monitoring of bridges.
The PM Gati Shakti National Master Plan should be fully utilized to ensure data-driven and integrated planning for infrastructure projects.
AI tools should be deployed to predict future needs, optimize logistics, and identify bottlenecks in infrastructure.
Increase public capital expenditure while promoting Public-Private Partnerships (PPP) for long-term project sustainability.
Encourage funding through municipal bonds, green bonds, and blended finance to attract institutional investments for infrastructure development.
India’s infrastructure development is marked by a paradox: while the country has made remarkable progress in areas like highways, metros, and aviation, recurring bridge collapses and other infrastructure failures expose deep flaws in quality control, maintenance, and accountability. To ensure the safety and sustainability of future infrastructure, India must reform its approach to planning, construction, maintenance, and oversight.
The recent discovery by a team at IIST, Thiruvananthapuram of circular polarization in radio emissions from a massive, young protostar is a remarkable breakthrough in astrophysics.
A protostar represents the early stage of a star’s life cycle, during which a giant molecular cloud in the interstellar medium begins to collapse under its own gravity. This process leads to the formation of a dense core that heats up as the cloud contracts.
Key stages of protostar evolution:
Formation: The collapse of a molecular cloud results in a protostar, a hot, dense mass of gas and dust.
Duration: The protostar phase lasts anywhere from 100,000 to 10 million years, depending on the star's mass.
Ending: The protostar phase transitions into the pre-main-sequence stage, where the star is known as a T-Tauri star if it's of similar mass to the Sun.
Main Sequence: The protostar eventually ignites hydrogen fusion in its core, marking the transition to a main sequence star.
However, because protostars are surrounded by dense dust, they are difficult to observe in visible light, which makes radio observations a valuable tool for studying them.
Circular polarization occurs when the electric and magnetic vectors of radio waves rotate around the wave's direction of travel. This special property of the radio emission helps scientists probe the magnetic fields near the protostar.
Magnetic Fields: Measuring circular polarization provides insights into the magnetic fields surrounding the protostar, which is crucial for understanding how stars like this one form. The magnetic fields can also influence the formation of protostellar jets.
New Observations: This study marks the first direct measurement of a magnetic field near a massive protostar (specifically, IRAS 18162-2048), revealing a field that is about 100 times stronger than Earth's. This is a breakthrough, as magnetic fields in massive protostars had been difficult to measure until now.
Protostellar Jets: The magnetic fields are thought to play a key role in the formation of bipolar jets of high-velocity material that are ejected from the protostar. These jets are crucial in shaping the environment around a protostar and contribute to the overall dynamics of star formation.
This discovery is a crucial step forward in our understanding of the star formation process, especially for massive stars, which are much harder to study than lower-mass stars like the Sun. The ability to measure magnetic fields and observe protostellar jets through radio polarization opens up new possibilities for astronomers to explore how stars, planets, and other cosmic objects evolve.
The Poshan Tracker App is a key digital tool rolled out by the Ministry of Women and Child Development, designed to support the Poshan Abhiyaan Initiative aimed at combating malnutrition in India. However, despite its potential, Anganwadi Workers (AWWs) are facing several challenges in using the app, primarily due to technical glitches and connectivity issues.
Launched on March 1, 2021, the Poshan Tracker is a mobile-based application that functions as a specialized digital platform for Anganwadi Centers (AWCs), Anganwadi Workers (AWWs), and beneficiaries. It is a critical tool for improving nutrition service delivery and supporting the government's fight against malnutrition.
Direct Data Capture: AWWs can record attendance, track the distribution of nutritional supplements, and update health parameters for children, pregnant women, and lactating mothers directly from the field.
Real-time Updates: The app offers real-time updates on nutrition indicators, helping government authorities keep track of resource usage, stock availability, and beneficiary outreach.
Timely Reporting: It enables real-time reporting for decision-making and prompt intervention by authorities.
Access Control: The app’s access is limited to designated users, including government-authorized staff and registered beneficiaries.
Launched in March 2018, the Poshan Abhiyaan aims to address the nutritional status of adolescent girls, pregnant women, lactating mothers, and children aged 0-6 years. The initiative targets a reduction in stunting, undernutrition, anaemia, and low birth weight among these vulnerable groups.
Reduce stunting in children (0-6 years).
Reduce undernutrition in children (0-6 years).
Reduce anaemia prevalence in children (6-59 months) and in women and adolescent girls (15-49 years).
Reduce low birth weight (LBW).
Despite its benefits, many Anganwadi Workers have expressed frustration with the app due to technical glitches and connectivity issues.
Technical Glitches: Workers often experience bugs and app crashes, leading to data loss or inaccurate reporting. These glitches can delay the tracking of crucial nutrition data, which impacts the timely delivery of services.
Connectivity Issues: In many rural and remote areas, internet access is unreliable, making it difficult for workers to update records or transmit real-time data. This slows down the decision-making process, impacting the efficiency of the Poshan Abhiyaan.
Efficiency in Service Delivery: The Poshan Tracker app is meant to make nutrition services more efficient, allowing Anganwadi Workers to monitor and report nutrition indicators directly from the field. However, technical barriers are limiting its effectiveness.
Impact on Malnutrition Efforts: The Poshan Abhiyaan Initiative targets critical areas such as undernutrition and anaemia, which affect millions of children, adolescent girls, and women in India. Delays or inaccuracies in data reporting can hinder the timely intervention that could otherwise help address these issues.
Monitoring and Accountability: The Poshan Tracker is integral to government monitoring and ensuring the success of the initiative. Without real-time data, it becomes challenging for authorities to track progress and make necessary adjustments to policies or interventions.
To address these challenges, it may be essential for the Ministry of Women and Child Development to:
Upgrade the App: Ensuring better technical support and regular updates to fix bugs and improve stability.
Improve Connectivity: Collaborating with the telecommunication sector to improve internet access in rural and remote areas where the app is most needed.
Training and Support: Providing ongoing training and technical assistance to Anganwadi Workers to ensure they can effectively use the app, even when faced with connectivity challenges.
The Poshan Tracker App has great potential to enhance the Poshan Abhiyaan Initiative and significantly improve nutrition outcomes in India. However, addressing the technical glitches and connectivity issues faced by Anganwadi Workers is crucial to its success.

A team from the Indian Institute of Technology (IIT) Kanpur has made a fascinating discovery in Yamuna Nagar district of Haryana, uncovering signs of ancient Buddhist stupas and structural remains buried beneath the soil.
Ground Penetrating Radar (GPR) is a powerful non-destructive geophysical method used to detect and image the subsurface of the Earth or other solid materials. It uses high-frequency electromagnetic pulses to send waves into the ground, which then interact with buried objects or boundaries, providing detailed insights without disturbing the surface.
Transmission of Electromagnetic Pulses:
A transmitter antenna sends high-frequency electromagnetic waves (ranging from 10 MHz to 1,000 MHz) into the ground.
Wave Interaction:
As these waves travel downward, they encounter objects or boundaries that have different electromagnetic properties from their surroundings (such as buried objects, foundations, or utilities).
Reflection and Return:
Part of the wave energy is reflected or scattered back to the surface when it hits a boundary or object. This reflected energy is captured by a receiver antenna.
Recording Data:
The receiver records the amplitude and arrival time of the reflected waves, which is then processed to produce an image of the subsurface. The digital storage device holds the data for analysis.
Archaeology:
GPR is widely used in archaeology to locate buried artifacts, structures, and ancient remains, such as the recent discovery in Yamuna Nagar. This allows archaeologists to explore sites without damaging the soil or disturbing cultural heritage.
Utility Detection:
It helps locate underground utilities, such as water pipes, gas lines, sewer systems, and telecommunications cables, ensuring safe construction and maintenance projects.
Engineering and Construction:
GPR is used to survey the integrity of concrete structures, such as bridges and roads, to detect hidden defects or cracks.
Environmental Studies:
It aids in investigating the subsurface environment for contamination or to map groundwater flow.
Forensic Investigations:
GPR is increasingly being used in forensic investigations to locate buried bodies, weapons, or other objects that may assist criminal investigations.
Non-destructive Exploration:
Unlike traditional excavation methods, GPR allows for non-invasive exploration of ancient sites, preserving the integrity of the area and reducing the risk of damaging important artifacts or structures.
Enhanced Discovery of Buried Structures:
In this case, GPR helped the IIT Kanpur team detect ancient Buddhist stupas and other structural remains without disturbing the ground. Such discoveries provide valuable insights into past civilizations, helping to trace their religious, cultural, and architectural significance.
Time and Cost Efficient:
GPR saves significant time and resources by allowing archaeologists to locate potential sites and plan targeted excavations instead of conducting large-scale digs without prior knowledge of what lies beneath the surface.
Precision:
The technology provides detailed imaging of the subsurface, allowing archaeologists to pinpoint the exact location and depth of buried objects or structures, leading to more efficient excavations and less disruption to the surrounding environment.
The discovery made by IIT Kanpur's team in Yamuna Nagar, Haryana is particularly significant as it sheds light on the Buddhist heritage of India. The Buddhist stupas are symbolic of the spread of Buddhism in ancient India, and their presence in the region indicates the historical and cultural importance of the area.
The use of GPR allowed the researchers to uncover ancient structural remains without physically digging into the earth, preserving the site for further study and excavation.
This discovery could provide important clues about the spread of Buddhism, ancient architectural techniques, and the socio-cultural dynamics of the time.
The application of Ground Penetrating Radar has transformed the way archaeological sites are explored, offering a safe, efficient, and precise method to uncover the past. This recent discovery in Yamuna Nagar is an example of how technology can aid in preserving cultural heritage while also pushing the boundaries of historical knowledge. It opens new doors for future archaeological explorations and enhances our understanding of ancient civilizations.
