Recent remarks by the Prime Minister of Nepal on the Kalapani–Lipulekh–Limpiyadhura boundary dispute, emphasizing an objective examination of facts and an amicable resolution through dialogue, along with renewed high-level diplomatic engagements, indicate a potentially more pragmatic phase in India–Nepal relations.

Nepal's emerging leadership is increasingly prioritizing economic development, sovereign equality, and constructive diplomacy, creating opportunities for a more balanced and forward-looking bilateral partnership. However, challenges relating to border disputes, Chinese influence, open-border security, and water-sharing continue to shape the relationship.

India–Nepal Boundary Dispute

Treaty of Sugauli (1816)

The roots of the dispute lie in the Treaty of Sugauli (1816), signed between the Kingdom of Nepal and the British East India Company after the Anglo-Nepalese War. The treaty designated the Kali (Mahakali) River as Nepal's western boundary but did not clearly identify its source, giving rise to competing territorial claims.

Nepal's Position

Nepal maintains that the Kali River originates from Limpiyadhura, the westernmost stream in the region. Based on this interpretation, Kalapani, Lipulekh, and Limpiyadhura fall within Nepalese territory.

To formalize its claim, Nepal amended its Constitution in 2020 to incorporate a revised political map including these territories. The government subsequently reinforced its position by issuing a new NPR 100 banknote carrying the updated map.

India's Position

India argues that the river originates near Kalapani, east of Limpiyadhura, and therefore regards the disputed territory as part of Pithoragarh district of Uttarakhand. India exercises both administrative and military control over the region.

Strategic Importance

The disputed area holds significant strategic value because of its proximity to China. The Lipulekh Pass serves as an important trade route and constitutes one of the principal gateways for the Kailash Mansarovar Yatra, enhancing its geopolitical and economic significance.

Changing Nature of Nepal's Approach Towards India

From Ideology to Pragmatism

Nepal is increasingly emphasizing economic cooperation over political rhetoric. This shift is evident in the agreement to export 10,000 MW of hydropower to India over the next decade, reflecting a stronger focus on mutual economic gains.

From Special Relationship to Sovereign Equality

Kathmandu seeks a relationship based on sovereign equality and mutual respect, moving beyond the traditional narrative of a special relationship. Nepal increasingly emphasizes diplomatic parity and independent decision-making in its interactions with India.

A More Rational Approach to Border Issues

Boundary disputes are gradually being treated as technical and diplomatic matters rather than instruments of nationalist mobilization. The preference for dialogue and evidence-based solutions indicates a more pragmatic approach to bilateral differences.

Greater Strategic Autonomy

Nepal seeks to pursue an independent foreign policy that balances its relations with both India and China while relying on diplomacy, historical evidence, and national interests rather than external alignments.

Key Outcomes of Nepal's Foreign Minister's Visit to India

Cross-Border Digital Payments

India and Nepal launched a Peer-to-Peer (P2P) linkage connecting India's Unified Payments Interface (UPI) with Nepal's National Payments Interface (NPI). The initiative enables real-time and low-cost cross-border remittances, deepening financial integration and promoting financial inclusion.

Language Technology Cooperation

An MoU between Digital India Bhashini and Kathmandu University aims to develop a voice-first digital language translation platform in Nepal, strengthening technological collaboration and digital accessibility.

Enhanced market access, industrial cooperation, tourism development, and investment in manufacturing and services can deepen economic interdependence between the two countries.

Challenges in India–Nepal Relations

Boundary Disputes

The unresolved Kalapani–Lipulekh–Limpiyadhura issue continues to influence bilateral relations and requires sustained diplomatic engagement and confidence-building measures.

China's Growing Influence

China's expanding economic and strategic presence in Nepal through the Belt and Road Initiative (BRI) presents new geopolitical challenges for India in the Himalayan region.

Open Border Security

The India–Nepal open border, while facilitating people-to-people ties, also poses challenges relating to illegal migration, smuggling, trafficking, and cross-border criminal activities.

Water-Sharing and River Management

Differences over water resources, flood management, and hydropower projects remain important issues requiring institutional cooperation and mutual trust.

Overview

The India–Nepal relationship is a cornerstone of India's Neighbourhood First Policy and is characterized by deep historical, cultural, economic, and strategic linkages. The two countries share an open border, close people-to-people ties, strong defence cooperation, and growing economic integration, making the partnership one of the most unique in South Asia.

Trade and Economic Relations

India is Nepal's largest trading partner and biggest export destination. At the same time, Nepal has emerged as India's 14th largest export destination in 2024–25, improving significantly from the 28th position in 2014.

Nepal primarily exports edible oils, tea, coffee, jute, and agricultural products to India, while it depends heavily on India for imports of petroleum products, iron and steel, cereals, vehicles, machinery, and manufactured goods. The extensive economic interdependence reflects the close integration of the two economies.

Defence and Security Cooperation

The defence relationship between the two countries is built upon deep institutional trust and shared military traditions. The Gorkha Regiment of the Indian Army includes nearly 32,000 Gorkha soldiers from Nepal, symbolizing a unique military partnership.

Military cooperation is further strengthened through the annual 'Surya Kiran' joint military exercise, which enhances interoperability, combat readiness, counter-terrorism capabilities, and disaster-response coordination between the armed forces of both nations.

The two countries also cooperate extensively in border management, intelligence sharing, and efforts to combat transnational crimes and terrorism.

Cross-Border Connectivity Infrastructure

Physical connectivity between India and Nepal has expanded considerably in recent years. Important cross-border railway projects include the Jayanagar–Bijalpura–Bardibas railway line, which represents Nepal's first broad-gauge railway connection, along with the Jogbani–Biratnagar rail link and the proposed Raxaul–Kathmandu railway project.

The Mechi Bridge, spanning the Mechi River, serves as an important international border crossing connecting Panitanki in West Bengal with eastern Nepal, facilitating trade and movement of people.

Energy connectivity has also improved through the Motihari–Amlekhgunj petroleum pipeline, commissioned in 2019 as South Asia's first cross-border petroleum pipeline, ensuring reliable and cost-effective fuel supplies to Nepal.

Energy and Digital Integration

Energy cooperation has emerged as a major pillar of bilateral relations. Under the Power Trade Agreement of 2024, Nepal is committed to exporting 10,000 MW of hydropower to India over the next decade, strengthening regional energy security and supporting India's clean energy transition.

Digital integration has witnessed significant progress through the operationalization of cross-border QR-based payments enabled by interoperability between India's Unified Payments Interface (UPI) and Nepal's FonePay system. This initiative facilitates seamless financial transactions and enhances economic connectivity.

River Basin Management and Water Cooperation

The two countries share several major transboundary rivers, making water cooperation an important aspect of bilateral relations. Long-standing agreements such as the Kosi Agreement (1954), Gandak Agreement (1959), and the Mahakali Treaty (1996) provide frameworks for cooperation in irrigation, flood control, hydropower development, and water resource management.

Cooperation also extends to the Karnali River basin, reflecting the strategic importance of water resources for both countries.

Disaster Management and Soft Power

India has consistently acted as the first responder during humanitarian crises in Nepal. Indian assistance during the 2015 Nepal earthquake and the Covid-19 pandemic demonstrated the strength of bilateral cooperation in Humanitarian Assistance and Disaster Relief (HADR) operations.

Cultural diplomacy remains another important dimension of the relationship. The Buddhist Circuit and Ramayana Circuit under India's Swadesh Darshan Scheme connect important religious and cultural centres such as Lumbini, the birthplace of Lord Buddha, and Janakpur, associated with Goddess Sita, thereby strengthening civilizational ties.

Strategic Importance of India–Nepal Relations

Nepal as a Geographic Buffer

Nepal occupies a critical position between India and China, functioning as an important buffer state in the Himalayan region. Stability in Nepal contributes significantly to India's northern security environment and helps safeguard the Indo-Gangetic plains from potential strategic threats.

Security of the Siliguri Corridor

A stable and friendly Nepal is crucial for the security of India's Siliguri Corridor, commonly known as the Chicken's Neck, which connects mainland India with the northeastern states. Any external influence or instability in Nepal could have significant implications for this strategically sensitive region.

Open Border Security

The 1,751-kilometre open border facilitates extensive people-to-people interactions, trade, employment, and cultural exchanges. However, it also necessitates close cooperation to address challenges such as smuggling, illegal migration, human trafficking, and cross-border criminal activities.

Countering China's Growing Influence

China has significantly expanded its presence in Nepal through the Belt and Road Initiative (BRI) and various infrastructure projects. For India, strengthening economic integration, connectivity projects, and development partnerships remains essential to maintaining its strategic influence and preserving Nepal's close engagement with South Asia.

Water and Energy Security

Nepal's river systems play a vital role in flood management and irrigation in northern India, while its immense hydropower potential contributes to India's renewable energy ambitions. Enhanced cooperation in water and energy therefore serves mutual strategic interests.

Challenges in India–Nepal Relations

The China Factor

Nepal's increasing engagement with China through BRI projects, the proposed Trans-Himalayan Railway, and Chinese-funded infrastructure such as Pokhara International Airport has raised strategic concerns in India regarding regional influence and security dynamics.

Legacy of the 2015–16 Blockade Controversy

The Madhesi protests of 2015–16 and Nepal's allegations of an unofficial Indian blockade generated anti-India sentiments within Nepal. Although India denied these accusations, the episode encouraged Nepal to diversify its external partnerships and strengthen relations with China.

Changing Diplomatic Dynamics

Nepal's contemporary leadership increasingly emphasizes sovereign equality, diplomatic protocol, and non-interference, moving away from the traditional notion of a special relationship with India. This requires a recalibration of bilateral engagement based on mutual respect and parity.

Open Border Challenges

The porous border facilitates transnational crimes, including smuggling, illegal migration, trafficking, and the circulation of Fake Indian Currency Notes (FICN). India's Sashastra Seema Bal (SSB) regularly intercepts illegal cross-border movements, highlighting the security challenges associated with an open border system.

Water-Sharing and Flood Management Issues

Despite extensive cooperation, disagreements continue regarding water-sharing arrangements and project implementation on the Kosi, Gandak, and Mahakali rivers. Delays in projects such as the 5,040 MW Pancheshwar Multipurpose Project and disputes relating to embankment maintenance and waterlogging in Nepal's Terai region remain important irritants.

Media-Driven Nationalism

Nationalistic narratives and media controversies often intensify bilateral disputes. Issues such as Nepal's issuance of NPR 100 banknotes featuring disputed territories demonstrate how domestic political considerations can influence public perceptions and diplomatic relations.

Measures to Strengthen India–Nepal Relations

Modernizing Bilateral Frameworks

Both countries should review the Eminent Persons Group (EPG) Report and consider updating aspects of the 1950 Treaty of Peace and Friendship to address Nepal's concerns regarding sovereign equality and contemporary geopolitical realities.

Improving Infrastructure Delivery

Timely completion of major projects such as the Arun-III Hydropower Project, cross-border railway links, and the expansion of the Motihari–Amlekhgunj pipeline will strengthen India's developmental credibility and deepen economic integration.

Depoliticizing Boundary Disputes

The Boundary Working Group (BWG) and Foreign Secretary-level mechanisms should be empowered to address the Kalapani–Lipulekh–Limpiyadhura dispute through technical and diplomatic dialogue rather than political confrontation.

Transforming Water Cooperation

Accelerating the Pancheshwar Multipurpose Project, improving flood-management coordination on the Kosi and Gandak rivers, and developing transparent benefit-sharing mechanisms can convert water resources into engines of shared prosperity.

Expanding Energy Partnership

The successful implementation of the agreement to export 10,000 MW of hydropower from Nepal to India requires stronger cross-border transmission infrastructure and greater investment in renewable energy cooperation.

Strengthening People-to-People Ties

Educational exchanges, cultural connections, the open-border system, and the unique military relationship between the two countries should continue to serve as foundations for long-term trust and cooperation.

Respecting Nepal's Sovereign Sensitivities

India's engagement with Nepal must increasingly emphasize mutual respect, non-interference, and sovereign parity, reflecting Nepal's aspirations for an equal partnership rather than a traditional special relationship.

Countering External Influence Through Connectivity

Instead of geopolitical competition, India can strengthen its position by deepening economic integration through railways, integrated check posts (ICPs), energy grids, digital connectivity, and trade facilitation, thereby remaining Nepal's most reliable development partner.

Conclusion

The emergence of a more pragmatic and economically oriented leadership in Nepal presents an opportunity to redefine bilateral relations on the basis of sovereign equality, economic integration, and mutual strategic interests. By addressing longstanding concerns, accelerating connectivity projects, and strengthening people-to-people linkages, India and Nepal can build a modern, resilient, and mutually beneficial partnership that contributes to stability and prosperity across the Himalayan region

 

India's 11,000-km coastline is increasingly vulnerable to sea-level rise, storm surges, cyclones, coastal erosion, and saline intrusion caused by climate change. These interconnected threats affect the lives and livelihoods of nearly 250 million people living in coastal areas. Strengthening coastal resilience has therefore become a major policy priority for sustainable development and climate adaptation.

Overreliance on Grey Infrastructure

India's coastal adaptation efforts have traditionally relied on grey infrastructure, including seawalls, groynes, embankments, and tetrapods, to protect vulnerable shorelines. Coastal States have invested substantially in such engineered solutions, while ecosystem-based measures have received comparatively less attention and funding.

Although grey infrastructure provides protection in densely populated and economically important regions, it often involves high construction and maintenance costs and can shift erosion and flood risks to neighbouring areas. Along parts of Kerala's coastline, hard armouring has protected certain stretches while intensifying erosion elsewhere, demonstrating the limitations of purely engineering-based approaches.

Ecosystem-Based Adaptation (EbA)

Ecosystem-Based Adaptation (EbA) refers to the use of biodiversity and ecosystem services to help communities adapt to the impacts of climate change. It integrates conservation, restoration, and sustainable management of ecosystems into climate adaptation strategies.

India possesses several natural ecosystems that function as effective coastal buffers, including mangroves, seagrass meadows, coral reefs, and wetlands. These ecosystems absorb wave energy, reduce shoreline erosion, mitigate storm impacts, and enhance resilience against extreme weather events.

Research has identified India as a global hotspot for coastal EbA, with mangrove ecosystems protecting more people per hectare than in most other countries.

Social, Economic, and Environmental Benefits

The benefits of EbA extend beyond environmental protection and contribute to social and economic development.

During Cyclone Dana, mangrove forests along the Odisha coast reduced the intensity of storm impacts and protected nearby communities. Similarly, in the Sundarbans, more than 18,000 women restored approximately 4,600 hectares of mangroves, strengthening resilience against Cyclones Amphan and Yaas.

These initiatives also generated livelihood opportunities through activities such as honey collection, crab farming, and ecosystem restoration work, demonstrating that EbA simultaneously supports climate resilience, social inclusion, biodiversity conservation, and economic development.

Governance and Policy Challenges

Despite its demonstrated effectiveness, EbA continues to occupy a marginal position within India's broader climate adaptation framework. Fragmented governance structures, weak monitoring mechanisms, and a preference for visible infrastructure projects often limit the recognition of ecosystem-based measures.

Many EbA initiatives are implemented under broader programmes related to conservation, restoration, or rural development, causing their adaptation benefits to remain unrecorded. Consequently, successful ecosystem interventions frequently receive limited attention in adaptation planning, financing, and evaluation processes.

The Challenge of Classification

An important obstacle to mainstreaming EbA is the presence of overlapping concepts such as Nature-based Solutions (NbS), Ecosystem-based Coastal Adaptation (EbCA), and Ecosystem-based Disaster Risk Reduction (Eco-DRR). The absence of clear distinctions among these approaches creates uncertainty regarding what constitutes climate adaptation.

As a result, several ecosystem initiatives are classified primarily as conservation or restoration programmes rather than adaptation measures. The Mangrove Initiative for Shoreline Habitats & Tangible Incomes (MISHTI) exemplifies this challenge. While the programme significantly enhances climate resilience through large-scale mangrove restoration, it is largely viewed as a restoration initiative instead of an adaptation strategy.

Importance of Recognition and Measurement

Proper recognition and classification of EbA are essential for accurately measuring adaptation outcomes and allocating resources effectively. Clear identification of ecosystem-based interventions enables policymakers to capture their full social, economic, and environmental benefits.

This assumes greater importance as international frameworks, including the Global Goal on Adaptation (GGA) under the Paris Agreement, increasingly focus on measuring adaptation progress. Without robust monitoring and classification systems, many of India's most effective climate adaptation measures may remain underreported and underfunded.

The Way Forward

India needs to integrate Ecosystem-Based Adaptation into mainstream coastal planning and climate policy while maintaining a balanced approach between natural and engineered solutions. Greater investment in mangrove restoration, wetland conservation, coral reef protection, and seagrass ecosystem management can provide cost-effective and sustainable protection against climate risks.

Strengthening governance mechanisms, developing clear classification frameworks, improving adaptation monitoring systems, and expanding climate finance for ecosystem-based initiatives will be crucial for scaling up EbA across coastal regions.

Conclusion

India's natural ecosystems constitute one of its most effective defences against climate change. While grey infrastructure will continue to play an important role in specific contexts, Ecosystem-Based Adaptation offers a more sustainable, equitable, and economically viable approach to coastal resilience. The central challenge now lies not in proving the effectiveness of EbA, but in ensuring that policy frameworks adequately recognise, measure, finance, and scale these nature-based solutions for long-term climate security and development.

 

 

 

A baby bust refers to a sustained decline in fertility rates that results in fewer births than are required to replace the existing population. A replacement-level fertility rate is generally considered to be 2.1 children per woman, which ensures long-term population stability in the absence of migration.

According to the Sample Registration System (SRS) and NFHS-5, India's Total Fertility Rate (TFR) has declined below the replacement level, falling from around 2.0 to 1.9. This indicates that India may experience population ageing and eventual population decline much earlier than previously anticipated.

India's Current Demographic Position

Most Indian States, particularly the southern and western States, now have fertility rates well below the replacement level. As a result, the country's population growth is slowing considerably, and population stabilization may occur sooner than earlier projections suggested.

This demographic transition marks a significant shift from concerns about population explosion to challenges associated with an ageing society and a shrinking workforce.

Reasons for Declining Fertility in India

Rising Female Education

Higher levels of female education have contributed to delayed marriages and childbirth. Increased participation of women in higher education and the workforce has also altered fertility preferences, leading to smaller family sizes.

Urbanisation

Rapid urbanisation has increased the cost of living, housing, healthcare, and education, making larger families economically less attractive. Urban societies increasingly favour the norm of smaller families.

Better Healthcare and Family Planning

The expansion of reproductive healthcare services, improved awareness, and greater availability of contraceptives have enabled couples to make informed choices regarding family size and birth spacing.

Declining Infant and Child Mortality

Improved healthcare has significantly reduced infant and child mortality rates. Families no longer need to have additional children as insurance against child deaths, contributing to lower fertility levels.

Changing Aspirations and Lifestyles

Modern families increasingly prioritize quality over quantity, investing more resources in education, health, and skill development for fewer children. Aspirational lifestyles and changing social values have further reinforced this trend.

Why Is It a Warning to the World?

Faster Demographic Transition

India demonstrates that fertility decline in developing countries can occur much faster than expected once socio-economic conditions improve. Many countries may therefore face ageing challenges earlier than anticipated.

Risks of a Shrinking Workforce

A declining youth population can reduce labour supply, slow economic growth, and increase the dependency ratio, placing greater pressure on the working-age population.

Rising Fiscal Burden

An ageing population requires higher expenditure on pensions, healthcare, and social security systems, creating long-term fiscal challenges for governments.

Growing Old Before Becoming Rich

Many developing nations risk becoming old societies before achieving high-income status. This phenomenon, often described as "growing old before growing rich," can limit economic development opportunities.

Lessons from East Asia

Countries such as Japan, South Korea, and China are already facing problems related to ageing populations, labour shortages, and persistently low fertility rates. India's demographic trajectory suggests that similar challenges may emerge in the coming decades.

Implications for India

Positive Outcomes

Demographic Dividend in the Short Term

Lower fertility reduces the dependency burden and creates opportunities for greater investment in education, health, and skill development. This can enhance productivity and support economic growth during the demographic dividend phase.

Better Human Development

Smaller family sizes enable improved maternal and child healthcare and allow greater investments in each child's education and overall development.

Emerging Challenges

Population Ageing

India will witness a growing elderly population, increasing the demand for geriatric healthcare, pension systems, and long-term care infrastructure.

Regional Demographic Imbalances

Southern States are likely to age faster due to lower fertility, while northern States may continue contributing a larger proportion of the country's workforce, potentially affecting political and economic dynamics.

Labour Market Pressures

Declining fertility may eventually create labour shortages in labour-intensive sectors, necessitating productivity improvements and technological adoption.

Social Security Challenges

Existing pension and healthcare systems will require substantial strengthening to support a larger elderly population in the future.

Government Initiatives

National Population Policy (NPP), 2000

The policy focuses on population stabilization through voluntary and informed choices, emphasizing reproductive health and family welfare rather than coercive population control measures.

Mission Parivar Vikas

The programme targets high-fertility districts and seeks to improve access to family planning services and reproductive healthcare.

National Programme for Health Care of the Elderly (NPHCE)

The programme addresses the healthcare requirements of an ageing population through specialized geriatric services and infrastructure.

Digital Health and Social Protection Measures

Initiatives such as Ayushman Bharat and expanding digital health infrastructure are strengthening India's preparedness for future demographic changes and ageing-related challenges.

The Way Forward

India must shift its focus from population control to population management, emphasizing demographic sustainability rather than further fertility reduction.

Greater investment in human capital, including education, healthcare, nutrition, and skill development, will be essential for maintaining economic growth despite slower population expansion.

Increasing female labour force participation through better childcare facilities and flexible employment opportunities can help offset future workforce shortages.

The country must also prepare for an ageing society by developing universal pension systems, elderly healthcare infrastructure, and long-term care services.

Finally, policies promoting labour reforms, technological innovation, productivity enhancement, and managed migration will be critical for sustaining economic development in an era of declining fertility

Researchers have recently rediscovered Vaccinium piliferum in the remote forests of Vijoynagar in Changlang district, Arunachal Pradesh, nearly 188 years after its first recorded observation.

About Vaccinium piliferum

Vaccinium piliferum is a rare and endangered wild relative of blueberry species. It belongs to the Ericaceae (heath) family, which also includes blueberries, cranberries, and bilberries. The species is native to the Eastern Himalayan region and is considered an important component of the area's unique plant diversity.

The plant was originally documented in 1836 during the colonial period but had not been recorded subsequently for nearly two centuries. Its recent rediscovery near the tributaries of the Noa-Dihing River in the dense forests of Arunachal Pradesh highlights the rich but underexplored biodiversity of the Eastern Himalayas.

Conservation Status

The International Union for Conservation of Nature (IUCN) has classified Vaccinium piliferum as an Endangered (EN) species, indicating that it faces a very high risk of extinction in the wild.

Key Facts about Blueberries

Blueberries belong to the Ericaceae (heath) family and comprise several species and varieties. Important types include Lowbush blueberry (Vaccinium angustifolium), Highbush blueberry (Vaccinium corymbosum), and Bilberry or Forest Blueberry (Vaccinium myrtillus).

Blueberry plants require a relatively cold climate, needing 150 to 1200 chilling hours to break dormancy and ensure proper flowering and fruiting. They grow best in well-drained, acidic, sandy loam soils with an organic matter content exceeding 3 percent. Extremely low temperatures, however, can damage shoots and flower buds.

Nutritional Importance

Blueberries are rich in essential nutrients such as Vitamin C, Vitamin K, and dietary fibre. They are also known for their high concentration of antioxidants, which help neutralize free radicals and contribute to overall health benefits.

 

 

The Mekedatu Project is a multi-purpose project proposed by the Government of Karnataka for drinking water supply and hydropower generation. It involves the construction of a balancing reservoir near Kanakapura in Ramanagara district, Karnataka, about 90 km from Bengaluru and nearly 4 km upstream of the Karnataka–Tamil Nadu border.

The project is planned at the confluence of the Cauvery River and its tributary, the Arkavathi River, making it strategically important in the Cauvery basin.

Key Features

The project envisages the construction of a 99-metre-high and 735-metre-long concrete gravity dam, along with an underground powerhouse and a water conductor system. The proposed reservoir will have a storage capacity of 67 thousand million cubic feet (tmcft) of water.

The stored water is intended primarily to meet the drinking water requirements of Bengaluru and surrounding areas, while the hydropower component is expected to generate 400 MW of electricity.

Environmental Concerns

The implementation of the project would lead to the submergence of more than 5,000 hectares of protected forest land within the Cauvery Wildlife Sanctuary. Environmental groups have raised concerns regarding the loss of biodiversity, habitat fragmentation, and the impact on wildlife in the region.

The Dispute with Tamil Nadu

The Mekedatu Project remains a major point of contention between Karnataka and Tamil Nadu. As the lower riparian state, Tamil Nadu has consistently opposed the project, arguing that it could adversely affect the flow of Cauvery waters into its territory.

According to Tamil Nadu, the Mekedatu region represents the last free-flowing point in Karnataka from where Cauvery water enters Tamil Nadu without obstruction. The state contends that the construction of a large balancing reservoir could enable Karnataka to regulate or withhold water flows, thereby affecting the implementation of the Cauvery water-sharing arrangements.

Recent Development

The Supreme Court recently dismissed Tamil Nadu's petition seeking a review of its November 2025 judgment, which had held that the challenge to Karnataka's proposed Mekedatu Balancing Reservoir-cum-Drinking Water Project was premature, as the necessary statutory approvals for the project had not yet been completed.
