Prelims level: Katchatheevu Island
Mains level: NA
Why in the news?
Prime Minister recently claimed that the then PM Indira Gandhi had given away the island of Katchatheevu to Sri Lanka for no reason.
About Katchatheevu Island
Katchatheevu is a small, uninhabited island measuring merely 285 acres, lying between India and Sri Lanka.
It is situated in the Palk Strait.
It was originally owned by the king of Ramnad (present-day Ramanathapuram, Tamil Nadu).
The island is used by fishermen to dry their nets.
Despite its modest size, the island holds significant religious significance, housing Anthony’s church, a centuries-old Catholic shrine revered by devotees from both nations.
Beyond its religious connotations, Katchatheevu is a vital ecosystem, supporting diverse flora and fauna endemic to the region’s maritime environment.
A Quick Recap of its History
During the British rule, it was administered jointly by India and Sri Lanka.
In the early 20th century, Sri Lanka claimed territorial ownership over the islet.
India ceded the island to Sri Lanka, through a joint agreement in 1974; India further gave up its fishing rights in the region in 1976.
Present Issue
In 1974 and 1976 treaties were signed between the two countries to demarcate the International Maritime Boundary Line (IMBL).
However, the agreement could not stop the fishermen from fishing in these waters, as fishermen know no boundary.
Culmination of the Political Dispute
Unresolved Issue: While Indian fishermen retained certain access rights to the island, the agreements failed to address key concerns regarding fishing rights, leading to simmering discontent among fishing communities.
Sri Lankan Atrocities: The civil war in Sri Lanka overshadowed the Katchatheevu issue, with Indian fishermen facing arrests and allegations of mistreatment by the Sri Lankan navy.
Renewed Demands: Instances of fishermen’s rights violations reignited calls for the retrieval of Katchatheevu by Tamil Nadu politicians, who highlighted the plight of affected fishing communities.
Present Backlash: The agreement sparked widespread protests and political backlash in Tamil Nadu, with regional parties and activists condemning the perceived abandonment of Indian sovereignty over Katchatheevu.

The mayor is usually elected by the membersof the Municipal Corporation or Council.
He/She serves as the ceremonial head of the local government.
History of Mayor’s elections in India
Municipal corporation mechanisms in India was introduced during British Rule with formation of municipal corporation in Madras (Chennai) in 1688, later followed by municipal corporations in Bombay (Mumbai) and Calcutta (Kolkata) by 1762.
However the process of introduction for an elected President in the municipalities was made in Lord Mayo’s Resolution of 1870.
Since then the current formand structure of municipal bodies followed is similar to Lord Ripon’s Resolution adopted in 1882 on local self-governance.
The 74th Constitutional Amendment Act of 1992 was introduced providing for the transfer of 18 different powers to urban local bodies, including the election of a mayor and to recognise them which included Municipal Corporations, Nagar Panchayats, and Municipal Councils.
Elections and tenure
The method of electing mayor and their tenure varies for each city in India.
In Bengaluru (Karnataka) the election process is indirect with a tenure being for one year.

Understanding Volcanoes
Volcanoes are geological features characterized by openings or vents through which lava, tephra (small rocks), and steam erupt onto the Earth’s surface.
They result from both their own eruptions and the broader processes of tectonic plate movement.
Volcanic eruptions are essentially the result of magma, or molten rock, beneath the Earth’s surface rising, bubbling, and ultimately overflowing, much like boiling milk spilling out of a pot on a stove.
The magma seeks pathways to vents within the volcano, where it erupts and is expelled across the land and into the atmosphere, a phenomenon referred to as lava.

The Dhanauri Wetlands is a bird-watching area located in Dhanauri village near Dankaur in Uttar Pradesh.
It is home to over 120 Sarus cranes (Sarus Cranes is the state bird of Uttar Pradesh).
It is a sanctuary for 23 species of endangered, critically endangered, and threatened birds, with special significance as a habitat for the majestic Sarus crane.
Ecological Significance
Dhanauri is a natural wetland that hosts more than 217 bird species, including over 150 Sarus cranes, and serves as a vital birding and nesting site.
It has received recognition as an Important Bird Area by Bird Life International and has been documented by the BNHS (Bombay Natural History Society).
During peak migratory seasons (November to March), the wetland hosts over 50,000 waterfowls.
Why in news?
Dhanauri plays a crucial role in supporting the vulnerable Sarus crane population.
The wetland fulfills two key Ramsar site criteria out of nine:
It hosts over 1% of the biogeographic Sarus crane population.
The area serves as a congregation site for 20,000+ waterfowls and various other species.
Ramsar Wetlands
The Ramsar Convention, also known as the ‘Convention on Wetlands,’ is an intergovernmental environmental treaty founded by UNESCO in 1971.
It derives its name from the city of Ramsar in Iran, where it was initially signed.
Ramsar sites are wetlands of global significance recognized under this treaty.
The Montreux Record is a register of wetland sites on the brink of ecological changes and in need of close monitoring under the Ramsar Convention.
Ramsar Site Designation Criteria:
Ramsar site designation hinges on several factors:
Representing rare or unique natural wetland types.
Supporting endangered species or threatened ecological communities.
Maintaining biodiversity in specific biogeographic regions.
Offering refuge during adverse conditions.
Regularly accommodating 20,000 or more waterbirds.
Sustaining 1% of a population of a single water-bird species.
Serving as a critical source of food, spawning grounds, nurseries, and migration paths for fish.
Regularly supporting 1% of a population of non-avian wetland-dependent animal species.
