Maharashtra’s plan to increase tigers count in Sahyadri-Konkan Wildlife Corridor by translocating tigers from Tadoba-Andhari Tiger Reserve (TATR) (Chandrapur, Maharashtra) underscores the critical role of wildlife corridors in conservation efforts.
About Tadoba-Andhari Tiger Reserve (TATR)
Tadoba became one of India’s earliest national parks when it was declared in 1955, alongside Kanha National Park.
The name “Tadoba” is derived from the deity “Tadoba” or “Taru,” worshipped by local Gond Tribals, and “Andhari” refers to the Andhari River flowing through the reserve.
It was later expanded and officially merged with the Andhari Wildlife Sanctuary in 1993 to form the TATR.
TATR is regarded as one of the world’s most preferred destinations for tiger sightings and is a critical part of Project Tiger, aimed at conserving tigers in India.
The reserve has 115 tigers, including 88 within the forest and 27 in the areas immediately surrounding the reserve.
About Sahyadri-Konkan Wildlife Corridor
The Sahyadri-Konkan corridor(Sahyadri-Radhanagari-Goa-Karnataka), plays a vital role in conserving wildlife, particularly tigers, in the northern Western Ghats region.
It spans throughout the states of Maharashtra, Goa, and Karnataka, specifically through the Western Ghats, one of the world’s eight biodiversity hotspots.
Protected Areas Connected:
Sahyadri Tiger Reserve (includes Koyna Wildlife Sanctuary (WLS) and Chandoli National Park) and Radhanagari Wildlife Sanctuary (Maharashtra);

From UPSC perspective, the following things are important :
Prelims level: Garo Hills
Mains level: NA
Why in the news?
Geological Survey of India (GSI) explorers have made a breakthrough, uncovering ancient fossils in Tolegre, South Garo Hills of Meghalaya.
It is speculated that the fossils could be linked to the genera Rhodocetus or Amulocetus (now extinct), considered ancestors of modern whales.
About Garo Hills
The Garo Hills, located in Meghalaya, are part of the Garo-Khasi range, one of the hill ranges in the northeastern region of India.
They are situated in the western part of Meghalaya, bordering Bangladesh to the south and west.

From UPSC perspective, the following things are important :
Prelims level: Thar Desert, Desert National Park;
Mains level: NA
Why in the News?
Rajasthan’s barren Thar Desert may turn green, says a recent study in the journal Earth’s Future.
Thar Desert
The Thar Desert is the 18th largest subtropical desert globally and is one of the most densely populated deserts.
Approximately 40% of the human population in Rajasthan resides in the Thar Desert.
It extends from the Sutlej River and is bounded by the Rann of Kutch, the Aravalli Mountains, and the Indus River.
About 85% of the Thar Desert is located in India, with the remainder in Pakistan.
In India, it spans across Rajasthan, Gujarat, Haryana, and Punjab as well.
Civilizations are believed to have thrived in the Thar region around 50,000 years ago across the extinct Saraswati River.
The Desert National Park (home to the endangered Great Indian Bustard, desert fox, desert cat, blackbuck, and Indian gazelle) is situated in the Thar Desert in the northwest Indian state of Rajasthan.
Why is the Thar desert getting greener?
Climate Change Effects:
Alteration of Weather Patterns: Climate change is causing shifts in rainfall distribution in the thar desert area.
Potential for Vegetation Growth: The increased precipitation could provide favorable conditions for vegetation growth, contributing to the greening of the desert.
Indian Monsoon Dynamics:
Westward Extension of Indian Monsoon: The Indian monsoon, known for bringing heavy rainfall to eastern India, is now extending further westward into regions like the Thar Desert.
Impact on Moisture and Rainfall: This change in monsoon dynamics could lead to increased moisture and rainfall in the desert region, facilitating the growth of vegetation.
Expansion of Indian Ocean Warm Pool (IOWP):
Influence on Monsoon Patterns: The Indian Ocean Warm Pool (IOWP) influences monsoon patterns and rainfall distribution over the Indian subcontinent.
Westward Expansion due to Climate Change: Climate change is causing the IOWP to expand westward, potentially resulting in increased rainfall over semi-arid regions like the Thar Desert and promoting greening.
Water Management Practices:
Contribution to Greening: Effective water management practices, such as rainwater harvesting and irrigation techniques like johad, kuis, and kunds, may be playing a role in the greening of the Thar Desert.
Utilization of Water Resources: By harnessing and efficiently utilizing available water resources, local communities and authorities can support vegetation growth and ecosystem restoration efforts in the desert.
Introduction of Irrigation
Commercial Cropping: Irrigation was introduced during British colonial rule in the 19th and 20th centuries to convert arid and semi-arid ecosystems into cropland.
Restrictions on Grazing: The right to graze animals was restricted to landowners who cultivated crops, leading to the transformation of nomadic pastoralists into sedentary agro-pastoralists.

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.

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.

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.

Hindu Influence: Evidence points to a pre-Islamic Hindu society, with remnants like buried idols and traditional songs hinting at past Hindu practices.
Conversion to Islam: A Gradual Transition
Arab Influence: Regular contact with Arab merchants and sailors led to the gradual conversion of islanders to Islam, distinct from the Islamic practices in mainland India.
Peaceful Introduction of Islam: Historian Mahmood Kooria notes that Islam’s introduction in the region, including Lakshadweep, was marked by minimal political conflict, primarily through commercial interactions.
Cultural Development: Insulation from Mainland Influences
Control by the Arakkal Kingdom: In the 16th century, the islands fell under the Arakkal kingdom of Kannur, Kerala’s only Muslim dynasty.
European Interactions: Despite conflicts with European powers, the islands maintained a degree of protection and isolation.

Religious and Sociological Interpretations
Islamic Justification for Matriliny: Islanders believe their matrilineal practice aligns with Islam, citing Prophet Muhammad’s life with his first wife, Khadija.
Sociological Viewpoint: Dr. N P Hafiz Mohamad emphasizes that the islanders see matriliny as integral to their Islamic practice.

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.

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.
