Mahadayi Diversion
Context
Why in News?
The Centre has clarified that no proposal seeking fresh environmental/“green” clearance for diversion of Mahadayi river water is currently pending before it, amid Karnataka’s efforts to implement the Kalasa-Banduri project. Recent reports also indicate that Karnataka’s clearance requests have faced difficulties because of the ongoing legal dispute over the Mahadayi Water Dispute Tribunal award.
Features
- What is the Mahadayi River?
- Mahadayi (Mandovi) originates in the Western Ghats of Karnataka.
- It flows through Karnataka and Goa and drains into the Arabian Sea.
- The river is important for drinking water, agriculture and ecosystems, particularly in Goa.
- What is the Kalasa-Banduri Project?
The Kalasa-Banduri Nala project is a Karnataka water-diversion project.
- Kalasa and Banduri are tributaries/nalas associated with the Mahadayi basin.
- Karnataka proposes to divert a portion of Mahadayi water towards the Malaprabha basin.
- The project is intended to improve drinking-water availability in northern Karnataka, including areas of Belagavi, Dharwad, Gadag and Bagalkot.
- Why is there a dispute?
The issue involves Karnataka, Goa and Maharashtra.
- Karnataka: Wants to use its allocated share of Mahadayi water, particularly for drinking-water needs.
- Goa: Opposes diversion because Mahadayi is crucial to its ecology, forests, agriculture and water security.
- Maharashtra: Is also a stakeholder in the river basin.
The Mahadayi Water Disputes Tribunal (MWDT) was constituted to adjudicate the dispute. Its final award was given in 2018, but the matter remains linked to proceedings before the Supreme Court.
- Environmental angle
The dispute is not merely about sharing water. It also involves the Western Ghats, a globally important biodiversity region.
Possible concerns:
- Impact on forest ecosystems
- Alteration of natural river flows
- Effects on wildlife habitats
- Changes in downstream water availability
- Ecological consequences in Goa
This creates a classic conflict between development needs and environmental protection.
Multi-Pair Kidney-Swap Transplant
Context
Why in News?
Karnataka became the first State in India to frame specific guidelines for multi-pair kidney paired-swap transplantation in April 2026. However, four months after the guidelines were issued, no multi-pair kidney-swap transplant has yet taken place in the State, highlighting the gap between policy approval and implementation.
What is Kidney Paired-Swap Transplantation?
Sometimes, a person who needs a kidney transplant has a willing donor within the family, but the donor’s kidney is biologically incompatible with the recipient—for example, because of blood-group or other compatibility issues.
In a paired exchange, two donor-recipient pairs are matched:
Pair A: Donor A → Recipient B
Pair B: Donor B → Recipient A
This allows both recipients to receive compatible kidneys.
What is Multi-Pair Kidney Swap?
A multi-pair exchange expands this system to three or more donor-recipient pairs.
For example:
Donor A → Recipient B → Donor B → Recipient C → Donor C → Recipient A
Thus, a larger chain can potentially create more compatible matches and help patients who otherwise cannot undergo transplantation.
Why did Karnataka introduce the guidelines?
The Karnataka Government issued the Karnataka Multi-Pair Kidney Exchange Transplantation Guidelines, 2026 through a Government Order dated April 4, 2026.
The guidelines were introduced because many donor-recipient pairs were unable to proceed with transplantation due to biological incompatibility. The new framework provides a mechanism for hospitals to seek approval for exchanges involving three or more pairs.
Legal Framework
The issue is connected with the Transplantation of Human Organs and Tissues Act (THOTA), 1994.
Under the earlier framework, kidney paired exchange was generally limited to an exchange between two incompatible donor-recipient pairs under Section 9(3A).
Karnataka’s 2026 guidelines establish an administrative and procedural framework for multi-pair exchanges, along with documentation, approval procedures and ethical safeguards.
Why has implementation been slow?
The delay illustrates that issuing guidelines alone does not automatically result in implementation.
Important requirements include:
- Identification of compatible donor-recipient combinations
- Registration of transplant hospitals
- Medical and biological compatibility assessment
- Approval by competent authorities
- Documentation and verification
- Ethical safeguards
- Coordination among multiple families and hospitals
Therefore, the challenge is now to translate the policy framework into actual transplantation while maintaining transparency, consent and ethical standards.
Significance for Healthcare
- Expands the donor pool
Multi-pair exchange can connect several incompatible pairs and increase the possibility of finding compatible kidneys.
- Helps address organ shortage
Kidney transplantation faces a major challenge because the demand for organs is much greater than the available supply.
- Promotes better use of willing donors
A willing family donor who cannot directly donate because of incompatibility may still help their relative through an exchange chain.
- Raises ethical and regulatory issues
Organ transplantation requires strong safeguards against commercialisation, coercion and exploitation. Hence, regulation and monitoring are essential.
The Federal Dilemma of Delimitation
Context
The Tamil Nadu Legislative Assembly has passed a resolution urging the Union Government to retain the present 543 Lok Sabha seats and maintain the existing State-wise distribution of seats. It has also sought implementation of one-third reservation for women from the 2029 Lok Sabha election, without waiting for a fresh delimitation exercise. This has renewed the debate over delimitation, democratic equality and Indian federalism.
Features
What is Delimitation?
Delimitation means the process of redrawing the boundaries of electoral constituencies and readjusting the allocation of seats in the Lok Sabha and State Legislative Assemblies based on population.
Its main objective is to ensure the principle of:
“One person, one vote, one value.”
The process is carried out by an independent Delimitation Commission constituted under an Act of Parliament.
Why is Delimitation a Federal Issue?
The major problem arises because India’s population has grown unevenly across States.
States with higher population growth
States such as Uttar Pradesh and Bihar have experienced relatively higher population growth.
States with lower population growth
States such as Tamil Nadu and Kerala achieved population stabilisation earlier through better education, healthcare and family-planning measures.
Therefore, if Lok Sabha seats are allocated strictly according to the latest population:
High-population States → likely to gain seats
Population-stabilised States → may lose their relative share of seats
This creates the argument that States which successfully controlled population growth could be politically penalised for their demographic success.
Why Were Lok Sabha Seats Frozen?
The allocation of Lok Sabha seats among States was frozen using the 1971 Census as the basis.
The objective was to ensure that States would not be disadvantaged politically for adopting population-control measures.
The 42nd Constitutional Amendment, 1976 froze the allocation of seats until after the first Census following 2000.
The 84th Constitutional Amendment, 2001 extended this freeze until the first Census after 2026.
The 87th Constitutional Amendment, 2003 allowed constituency boundaries to be adjusted using the 2001 Census, but without changing the total number of Lok Sabha seats allocated to each State.
The Core Constitutional Conflict
The debate involves two important democratic principles:
- Equal representation
A citizen’s vote should have approximately equal value.
If one MP represents a very large population while another represents a much smaller population, the principle of political equality is weakened.
- Federal balance
India is a Union of States.
States that have successfully stabilised their populations argue that their political representation should not decline merely because other States have experienced faster population growth.
Thus, the dilemma is:
Population-based representation vs Federal balance
Tamil Nadu’s Proposal
The Tamil Nadu Assembly has proposed:
- Keep the Lok Sabha strength at 543.
- Maintain the existing State-wise distribution of seats.
- Implement one-third reservation for women from 2029.
- Avoid linking women’s reservation to a fresh redistribution of Lok Sabha seats.
This reflects concerns that a major post-2026 delimitation could alter the political balance between States.
Women’s Reservation and Delimitation
The 106th Constitutional Amendment Act, 2023, popularly known as the Nari Shakti Vandan Adhiniyam, provides for one-third reservation of seats for women in the Lok Sabha and State Legislative Assemblies.
However, its implementation is linked to a delimitation exercise following the relevant Census.
Therefore, delimitation has implications not only for the number and distribution of seats, but also for the implementation of women’s reservation.
Possible Increase in Lok Sabha Seats
One proposal discussed in the debate is to increase the total strength of the Lok Sabha substantially rather than simply transferring seats from one State to another.
A larger House could accommodate population growth while reducing the extent to which some States lose their relative representation.
However, increasing the number of MPs also raises questions about:
- Parliamentary efficiency
- Cost to the exchequer
- Size and functioning of parliamentary committees
- Relationship between Lok Sabha and Rajya Sabha
- Quality of legislative deliberation
