Prelims level: Pulicat Wetland and its topography; Eco-sensitive Zones (ESZs)
Mains level: NA
Why in the news?
Settlement of claims for local communities within Pulicat Wetland and Birds Sanctuary boundary raises concerns.
State government plans to denotify a significant portion of the sanctuary and Eco-Sensitive Zone (ESZ) for industrial park development.
About Pulicat Wetland and Birds Sanctuary
Pulicat Lake Bird Sanctuary is the second-largest bird sanctuary in India.
It cuts across Nellore district of Andhra Pradesh and Thiruvallur district of Tamil Nadu.
The sanctuary is situated along the coast of the Bay of Bengal covering an area of 759 square kilometers.
The sanctuary is bordered by the Arani River at its southern tip, the Kalangi River from the Northwest, and the Swarnamukhi River at the northern end.
Pulicat Lake runs parallel to the Bay of Bengal and has a sand bar, making it a lagoon of its own kind.
Sriharikota, renowned as India’s rocket launch pad and home to the Satish Dhawan Space Centre, separates the lake from the Bay of Bengal.
The sanctuary includes 16 island villages and 30 villages adjoining the lake, whose inhabitants depend on the lake for their livelihood.
Pulicat Lake Bird Sanctuary hosts a large number of migratory birds during winter, including gulls, terns, plovers, shanks, curlews, and storks.
It is a habitat for a variety of bird species such as flamingos, pelicans, storks, herons, and ducks.
What are the Eco-sensitive Zones (ESZs)?
Eco-Sensitive Zones (ESZs) or Ecologically Fragile Areas (EFAs) are areas notified by the MoEFCC around Protected Areas, National Parks and Wildlife Sanctuaries.
The purpose of declaring ESZs is to create some kind of “shock absorbers” to the protected areas by regulating and managing the activities around such areas.
They also act as a transition zone from areas of high protection to areas involving lesser protection.
How are they demarcated?
The Environment (Protection) Act, 1986 does NOT mention the word “Eco-Sensitive Zones”.
However, Section 3(2)(v) of the Act, says that Central Government can restrict areas in which any industries, operations or processes or class of industries, operations or processes shall be carried out or shall not, subject to certain safeguards.
Besides Rule 5(1) of the Environment (Protection) Rules, 1986 states that central government can prohibit or restrict the location of industries and carrying on certain operations or processes on the basis of certain considerations.
The same criteria have been used by the government to declare No Development Zones (NDZs).
Defining its boundaries
An ESZ could go up to 10 kilometres around a protected area as provided in the Wildlife Conservation Strategy, 2002.
Moreover, in the case where sensitive corridors, connectivity and ecologically important patches, crucial for landscape linkage, are beyond 10 km width, these should be included in the ESZs.
Further, even in the context of a particular Protected Area, the distribution of an area of ESZ and the extent of regulation may not be uniform all around and it could be of variable width and extent.

Prelims level: Mount Ruang, Pacific Ring of Fire, Sangihe Islands arc, Tectonic Plates mentioned
Mains level: NA
Why in the news?
Indonesia witnessed a series of eruptions from Mount Ruang, a stratovolcano located in North Sulawesi Province.
About MountRuang
Ruang is situated in the Sangihe Islands arc, North Sulawesi, Indonesia.
It comprises an island that is 4 by 5 kilometers wide, with a summit containing a partial lava dome reaching an altitude of 725 meters (2,379 ft).
From its summit, peaks such as Klabat, Siau, and Ternate can be observed in the south, north, and east, respectively.
The volcano’s first recorded eruption was in 1808.
Why so many volcanic eruptions in Indonesia this year?
Indonesia, an archipelago of 270 million people, has 120 active volcanoes.
It is prone to volcanic activity because it sits along the “Ring of Fire,” a horseshoe-shaped series of seismic fault lines around the Pacific Ocean.
What is the Pacific ‘Ring of Fire’?
The Pacific ‘Ring of Fire’ or Pacific Rim, or the Circum-Pacific Belt, is an area along the Pacific Ocean that is characterized by active volcanoes and frequent earthquakes.
Volcanic arcs and oceanic trenches partly encircling the Pacific Basin form the so-called Ring of Fire.
It is home to about 75 per cent of the world’s volcanoes – more than 450 volcanoes.
Also, about 90 per cent of the world’s earthquakes occur here.
Its spread
Its length is over 40,000 kilometres and traces from New Zealand clockwise in an almost circular arc covering Tonga, Kermadec Islands, Indonesia.
It is moving up to the Philippines, Japan, and stretching eastward to the Aleutian Islands, then southward along the western coast of North America and South America.
Seismic activity of the region
The area is along several tectonic plates including the:
Pacific plate,
Philippine Plate,
Juan de Fuca plate,
Cocos plate,
Nazca plate, and
North American plate.
The movement of these plates or tectonic activity makes the area witness abundant earthquakes and tsunamis every year.
Along much of the Ring, tectonic plates move towards each other creating subduction zones.

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.

Prelims level: Mayor in ULBs, Powers and functions
Mains level: NA
PC: Hindustan Times
Introduction
The Supreme Court has nullified the outcome of the mayoral election held on January 30 in Chandigarh.
Who is a Mayor?
In India, the mayor is the head of an urban local body, which is responsible for providing essential services and infrastructure to the residents of a city or town.
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.
In Mumbai (Maharashtra) it follows indirect elections with tenure for 2.5 years and Bhopal (Madhya Pradesh) follows a directly elected mayor with a term for 5 years.
Roles and Responsibilities
Governs the local civic body.
Fixed tenure varying in different towns.
First citizen of city.
Has two varied roles:
Representation and upholding of the dignity of the city during ceremonial times and
Presiding over discussions of the civic house with elected representatives in functional capacity.
The Mayor’s role is confined to the corporation hall of presiding authority at various meetings relating to corporation.
The Mayor’s role extends much beyond the local city and country as the presiding authority at corporation meetings during visits of a foreign dignitary to the city as he is invited by the state government to receive and represent the citizens to the guest of honour.
At government, civic and other social functions he is given prominence.

Central Idea
The Sultanpur National Park has observed a 20-30% decrease in the number of migratory birds this season, as reported by forest department officials.
Estimates show a reduction in bird numbers, with current figures ranging between 8,000 to 10,000, compared to the expected 15,000.
About Sultanpur National Park
Sultanpur NP is located at Sultanpur village on Gurugram-Jhajjar highway, 15 km from Gurugram, Haryana and 50 km from Delhi.
It was a bird sanctuary, ideal for birding and bird lookers. Its area covers approximately 142.52 hectares.
Migratory birds start arriving in the park in September. Birds use the park as a resting place till the following March-April.
During summer and monsoon months the park is inhabited by many local bird species.
In April 1971, the Sultanpur Jheel inside the park (an area of 1.21 sq. km.) was accorded Sanctuary status under section 8 of the Punjab Wildlife Preservation Act of 1959.
The status of the park was upgraded to National Park in July 1991 under the Wildlife (Protection) Act, 1972.
Significance of the NP
Spanning 1.42 sq km, it is recognized as a national park, wildlife sanctuary, and a Ramsar site since 2021.
It is one of the few NPs in the small state of Haryana.
Another NP in Haryana is Kalesar National Park.
Important Fauna at the Park
Mammals: Blackbuck, Nilgai, Hog deer, Sambar, Leopard etc.
Birds: Siberian Cranes, Greater Flamingo, Demoiselle Crane etc.
Annual Migratory Patterns
Typical Arrival: Migratory birds usually begin arriving in the first week of October.
Annual Visitation: By the end of January each year, around 22,000 birds visit Sultanpur Park. However, this year’s numbers are anticipated to be much lower.
Possible Reasons for Reduced Migration
Temperature Changes: Wildlife experts suggests that milder winters in regions like Siberia, Central Asia, and Europe might be influencing migration patterns.
Food Availability: If migratory birds continue to find sufficient food in their native regions, they may not feel compelled to migrate.
Local Climate Impact: The local temperature at Sultanpur Park has not dropped significantly to align with the birds’ migratory patterns.
Effect of Smog: Smog and air pollution could also be contributing factors to the altered migratory behavior.

Prelims level: Kadalundi Mudflats
Mains level: NA
Central Idea
Kadalundi’s mudflats are shrinking drastically with sands cover.
These mudflats have been a vital source of sustenance for thousands of migrant shorebirds, offering abundant prey like polychaetes and crustaceans.
About Kadalundi Mudflats
Kadalundi Mudflats are situated in the Kadalundi Bird Sanctuary, which is located in the Kozhikode district of Kerala, along the southwestern coast of India. The sanctuary encompasses estuarine wetlands, mudflats, and mangrove forests.
The mudflats are part of the estuarine ecosystem formed at the confluence of the Kadalundi River and the Arabian Sea.
This unique environment is influenced by both freshwater from the river and saline water from the sea, creating a diverse habitat.
Ecological significance
Kadalundi Mudflats are renowned for their rich biodiversity, especially in terms of avian species.
The Kadalundi Bird Sanctuary and the mudflats are protected under the Wildlife Protection Act of 1972.
The mudflats serve as a critical habitat for various resident and migratory birds.
It is estimated that over 100 species of resident and migratory birds visit the area, making it a paradise for birdwatchers and ornithologists.
They are a crucial stopover point for migratory birds travelling along the East Asia-Australasia Flyway.
From UPSC perspective, the following things are important :
Prelims level: Mount Etna
Mains level: NA
Central Idea
Volcanic eruptions often make headlines only when iconic volcanoes like Etna, Kilauea, or Eyjafjallajokull erupt.
However, throughout any given year, our planet witnessed numerous volcanic eruptions, with as many as 50 to 80 occurring worldwide.
About Mount Etna
Mount Etna, located in Italy, holds the title of Europe’s most active volcano and ranks among the world’s largest.
Its recorded volcanic activity dates back to 1500 B.C., with over 200 eruptions documented since then.
Etna’s recent eruptions have disrupted air travel, leading to flight cancellations at the nearby Catania airport.
Additionally, the accumulation of volcanic ash on roads prompted authorities to temporarily ban the use of cars and motorbikes due to safety concerns.
Volcanic Eruptions this Year
Many of the world’s most active volcanoes are concentrated in the Pacific Ring of Fire, encompassing regions like New Zealand, Southeast Asia, Japan, and the western coast of the Americas. This volatile area also experiences about 90% of all earthquakes globally.
Kilauea, Hawaii: The Kilauea volcano in Hawaii captivated the world with a nearly nonstop eruption that began in 1983 and continued for an astonishing 35 years until 2018. Remarkably, it rekindled in 2021, with the eruption still ongoing.
Dukono, Indonesia: Erupting since August 1933, Dukono volcano in Indonesia stands as a testament to long-term volcanic activity, defying the passage of time.
Santa Maria, Guatemala: The eruption of Santa Maria in Guatemala commenced in June 1922 and persists to this day, underscoring the enduring nature of certain volcanic phenomena.
Yasur, Vanuatu: Yasur in Vanuatu first erupted around 1270 and has maintained its volcanic activity, continuing as of June 9, 2023.
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.
Types of Volcanoes

Notable Examples
Cinder Cones
Small, steep, conical
Formed from basaltic magma with high gas content
Often explosive eruptions with cinders/scoria
Paricutin (Mexico), Sunset Crater (USA)
Composite/Stratovolcanoes
Tall and symmetrical
Result from alternating layers of lava, ash, etc.
Both explosive and effusive eruptions
Mount St. Helens (USA), Mount Fuji (Japan)
Shield Volcanoes
Broad and gently sloping
Primarily formed from basaltic magma
Primarily non-explosive with extensive lava flows
Mauna Loa, Mauna Kea (Hawaii)
Lava Domes
Rounded dome-like shape
Formed from slow extrusion of viscous magma
Typically non-explosive but can be dangerous
Novarupta Dome (Alaska), Mount St. Helens’ Lava Dome (USA)
