The Katchatheevu Island has garnered significant attention due to its central role in the complex India-Sri Lanka relationship. It represents a persistent point of contention, primarily concerning maritime boundary disputes and the contentious issue of fishing rights.
This small, uninhabited island highlights the intricate challenges involved in managing shared maritime spaces and the livelihoods of traditional fishing communities.
Katchatheevu is located in the Palk Strait, a narrow strip of water separating the Indian state of Tamil Nadu from Sri Lanka. Its position is strategically significant for both nations.
It lies approximately 16 nautical miles (30 km) southwest of Jaffna, Sri Lanka, and about 10.5 nautical miles (19 km) northeast of Rameswaram, India.
Location: Palk Strait, between India and Sri Lanka.
Area: Approximately 285 acres (1.15 sq km).
Status: Uninhabited, ceded to Sri Lanka in 1974.
The most prominent aspect of the Katchatheevu dispute is the issue of traditional fishing rights. Indian fishermen, particularly from Tamil Nadu, have historically fished in the rich waters around the island.
Despite the island being formally ceded to Sri Lanka, these fishermen continue to venture into these waters, often leading to confrontations with the Sri Lankan Navy.
The status of Katchatheevu became a key factor in the demarcation of the maritime boundary between India and Sri Lanka. Agreements in 1974 and 1976 formally established the International Maritime Boundary Line (IMBL).
These agreements placed Katchatheevu firmly on the Sri Lankan side of the IMBL, thereby restricting Indian fishermen's access to what they consider their traditional fishing grounds.
The Katchatheevu Island issue encapsulates the complexities of historical claims, national sovereignty, international maritime law, and the crucial aspect of livelihoods of fishing communities in bilateral relations.
The recurring incidents of Indian fishermen being arrested by the Sri Lankan Navy frequently strain India-Sri Lanka relations. These events often trigger strong political reactions in Tamil Nadu and become a significant domestic issue in India.
Both governments face continuous pressure to find a sustainable and mutually acceptable solution that respects national sovereignty while protecting the economic interests and safety of their respective fishing populations.
When addressing India-Sri Lanka relations in UPSC Mains (GS Paper 2), the Katchatheevu issue and associated fishing rights are critical examples to illustrate ongoing challenges and areas of diplomatic engagement.
