Prelims level: Cyclone Biparjoy
Mains level: Naming of cyclone
PC: windy.com
Central Idea: A cyclonic storm, named Biparjoy, has developed in the Arabian Sea.
Cyclone Biparjoy
It was stationed about 850 km west of Goa and 900 km southwest of Mumbai.
The cyclone is predicted to gain in strength over the next three days and develop into a very severe cyclonic storm by June 13.
It would result in squally weather with wind speeds reaching 35-45 kmph along the coastline of Karnataka, Goa, and Maharashtra
The IMD has not yet predicted any major impact on countries adjoining the Arabian Sea, including India, Oman, Iran, and Pakistan.
How it was named?
Origin of Cyclone Biparjoy’s Name: ‘Biparjoy’ was suggested by Bangladesh and the word means ‘disaster’ or ‘calamity’ in Bengali. The next cyclone after Biparjoy will be named ‘Tej’ based on India’s suggestion.
Rotational Basis for Naming: The naming of cyclones is done by countries on a rotational basis, following certain existing guidelines.
Responsibilities of RSMCs and TCWCs: Worldwide, there are six regional specialized meteorological centers (RSMCs) and five regional Tropical Cyclone Warning Centers (TCWCs) mandated for issuing advisories and naming of tropical cyclones.
IMD’s Role: IMD is one of the six RSMCs providing tropical cyclone and storm surge advisories to 13 member countries under the WMO/Economic and Social Commission for Asia-Pacific (ESCAP) Panel.
Naming Authority of IMD: RSMC, New Delhi, is also mandated to name the tropical cyclones developing over the north Indian Ocean, including the Bay of Bengal and the Arabian Sea.
Guidelines for Naming: Some rules are to be followed while naming cyclones, such as being neutral to politics, religious beliefs, cultures, and gender, avoiding offensive or cruel names, and keeping the name short and easy to pronounce.
Next Cyclone Name: After Bangladesh, the next cyclone will be named ‘Tej’ based on India’s suggestion.
Cyclones in the Arabian Sea: A quick recap
Frequency of Cyclones: It is not rare for cyclones to develop in the Arabian Sea. There are fewer cyclones compared to the Bay of Bengal, but it is not uncommon.
Favorable Months: June is one of the favorable months for the formation of cyclones in the Arabian Sea.
Factors Influencing Cyclone Formation: Cyclones form due to low-pressure systems over warm waters. The Bay of Bengal is slightly warmer, but the Arabian Sea is also getting warmer due to climate change, leading to an increase in cyclones.
Coriolis Effect and Weather Systems: In a depression or low-pressure situation, the air blows in an anticlockwise direction in the northern hemisphere, influenced by the Coriolis Effect.
Role of Climate Change
Historical data indicates that the frequency of extremely severe cyclonic storms has increased over the Arabian Sea since 1990, while it has remained the same over the Bay of Bengal.
A 2021 study highlighted the increasing intensity, frequency, and duration of cyclonic storms in the Arabian Sea.
The warming is indicated by the nearly tripled accumulated cyclone energy, reflecting the extent of warming in recent years.

Prelims level: Solomon Islands
Mains level: Read the attached story
A Chinese state-backed company has won a contract to develop Honiara, a key port in the Solomon Islands. This is a major victory for China, which is seeking to gain a strategic foothold in the South Pacific.
Why discuss this?
The Solomon Islands have become a focal point in the diplomatic tussle between China and the US, following the signing of a secret security pact between the Solomons and Beijing in 2022.
This has raised concerns that China may be establishing a permanent naval base in the country.
About Solomon Islands
The Solomon Islands is a sovereign country consisting of six major islands and over 900 smaller islands in Oceania, to the east of Papua New Guinea and northwest of Vanuatu.
Its capital, Honiara, is located on the largest island, Guadalcanal.
It is part of the ethnically Melanesian group of islands in the Pacific and lies between Papua New Guinea and Vanuatu.
The country takes its name from the Solomon Islands archipelago, which is a collection of Melanesian islands that also includes the North Solomon Islands (a part of Papua New Guinea).
It excludes outlying islands, such as the Santa Cruz Islands and Rennell and Bellona.
Quick recap of its past
The islands, which were initially controlled by the British Empire during the colonial era, went through the hands of Germany and Japan.
It then went back to the UK after the Americans took over the islands from the Japanese during World War II.
The islands became independent in 1978 to become a constitutional monarchy under the British Crown, with a parliamentary system of government.
Nevertheless, its inability to manage domestic ethnic conflicts led to close security relations with Australia, which is the traditional first responder to any crisis in the South Pacific.
How did China enter the picture?
Earlier this year, the Solomon Islands established a security agreement with China, saying it needed Beijing’s assistance with its domestic security situation.
But the announcement had rattled the west, esp. the US, Australia and others in the Indo-Pacific region.
The concerns were that the agreement could potentially lead to a Chinese military base on the island nation and a gain in power-projection capabilities.
At that time, following intense scrutiny, the Solomon Islands had denied that the agreement would allow China to establish a naval base.
What is the Solomon Islands’ stance?
The government has asked all partner countries with plans to conduct naval visits or patrols to put them on hold until a revised national mechanism is in place.
The revised national mechanism applied to all foreign vessels seeking access to the country’s ports.
The nation wanted to build up itsown naval capacity.
It has some unfortunate experiences of foreign naval vessels entering its waters without any diplomatic clearance.
What is behind China’s growing influence in the region?
There is no dispute that China has been rapidly increasing its presence and influence in the region for over three decades, particularly in the South Pacific.
Certainly Beijing views the Pacific Island region as an important component of its Belt and Road Initiative (BRI).
Specifically, it sees the region as a critical air freight hub in its so-called Air Silk Road, which connects Asia with Central and South America.
Concerns of the West
The port project could open the door to a Chinese naval base, which would significantly extend China’s military reach in the South Pacific.”
It is likely that this security agreement between China and the Solomon Islands has been driven by, what the CFR calls, Beijing’s “sense of vulnerability” in the region.
What is the rationale for the Solomon Islands’ increasing proximity to China?
The Solomon Islands had cultivated strong ties with Taiwan, which ended with the emergence of the current government in Honiara.
In 2019, the regime change switched Taiwan for China.
This was supposedly after Beijing offered half a billion US dollars in financial aid, roughly five times what Taiwan spent on the islands in the past two decades.
It has been alleged by the pro-Taiwan Opposition that the incumbent government has been bribed by China.
Why is China interested in the Solomon Islands?
Isolating Taiwan: The Solomon Islands was one among the six Pacific island states which had official bilateral relations with Taiwan.
Supporter in UN: The small Pacific island states act as potential vote banks for mobilising support for the great powers in international fora like the United Nations.
Larger EEZ: These states have disproportionately large maritime Exclusive Economic Zones when compared to their small sizes.
Natural resources: Solomon Islands, in particular, have significant reserves of timber and mineral resources, along with fisheries.
Countering US: But more importantly, they are strategically located for China to insert itself between America’s military bases in the Pacific islands and Australia.
What does this mean for the established geopolitical configuration in the region?
Diminishing western influence: The Pacific islands, in the post-World War II scenario, were exclusively under the spheres of influence of the Western powers, in particular, the US, UK, France and Australia and New Zealand.
Inserting into western hegemony: All of them have territorial possessions in the region, with the three nuclear powers among them having used the region as a nuclear weapons testing ground.
Shifting of dependencies: The smaller island nations of the region are heavily dependent on them, especially Australia as it is a resident power.

From UPSC perspective, the following things are important :
Prelims level: Silent Valley National Park
Mains level: NA
A bird survey conducted at the Silent Valley National Park identified 141 species, of which 17 were new. So far, 175 species of birds have been spotted in Silent Valley.
Silent Valley National Park
It is located in the border of Mannarkkad Taluk of Palakkad district, Nilambur Taluk of Malappuram district, Kerala, and Nilgiris district of Tamil Nadu.
This national park has some rare species of flora and fauna. This area was explored in 1847 by the botanist Robert Wight.
It is located in the rich biodiversity of Nilgiri Biosphere Reserve.
Mukurthi peak, the fifth-highest peak in South India, and Anginda peak are also located in its vicinity.
Bhavani River, a tributary of Kaveri River, and Kunthipuzha River, a tributary of Bharathappuzha river, originate in the vicinity of Silent Valley.
The Kadalundi River has also its origin in Silent Valley.
New species spotted
Brown wood owl, Banded bay cuckoo, Malabar woodshrike, White-throated kingfisher, Indian nightjar, Jungle nightjar, and Large cuckooshrike were among the 17 species newly identified in the Silent Valley.
From UPSC perspective, the following things are important :
Prelims level: Great Lakes
Mains level: Not Much
Scientists are building a sensor network to detect the trends in the water chemistry of Lake Huron, one of the five Great Lakes of North America.
What is the Acidification of water bodies?
Acidification of oceans or freshwater bodies takes place when excess carbon dioxide in the atmosphere gets rapidly absorbed into them.
Scientists initially believed this might be a good thing, as it leaves less carbon dioxide in the atmosphere.
But in the past decade or so, it has been established that absorption of carbon dioxide leads to a lowering of the pH, which makes the water bodies more acidic.
What are Great Lakes?
The Great Lakes are a series of large interconnected freshwater lakes in the mid-east region of North America that connect to the Atlantic Ocean via the Saint Lawrence River.
There are five lakes, which are Superior, Michigan, Huron, Erie, and Ontario and are in general on or near the Canada–US border.
Hydrologically, lakes Michigan and Huron are a single body joined at the Straits of Mackinac.
By itself, Lake Huron is the world’s third largest freshwater lake, after Lake Superior and Lake Victoria.
The Great Lakes Waterway enables modern travel and shipping by water among the lakes.
Why are they significant?
The Great Lakes contain a fifth of the world’s total freshwater, and is a crucial source of irrigation and transportation.
They also serve as the habitat for more than 3,500 species of plants and animals.
Acidification of Great Lakes
Scientists are developing a system that would be capable of measuring the carbon dioxide and pH levels of the Great Lakes over several years.
It is known that the increase in atmospheric carbon dioxide has caused the world’s oceans to turn more acidic.
Recently, it has been observed that by 2100, even the Great Lakes — Superior, Michigan, Huron, Erie, and Ontario — might approach acidity at around the same rate as the oceans.
Researchers hope the data from the Lake Huron project would add to scientific information on the subject.
Consequences of acidification
The Great Lakes are believed to have been born some 20,000 years ago, when the Earth started to warm and water from melting glaciers filled the basins on its surface.
However, this rich ecosphere is under threat as the five lakes would witness a pH decline of 0.29-0.49 pH units — meaning they would become more acidic — by 2100.
This may lead to a decrease in native biodiversity, create physiological challenges for organisms, and permanently alter the structure of the ecosystem, scientists say.
It would also severely impact the hundreds of wooden shipwrecks that are believed to be resting at the bottom of these lakes.

Prelims level: Arittapatti, Biodiversity Heritage Site (BHS)
Mains level: Not Much
The Tamil Nadu Government has issued a notification declaring Arittapatti in Melur block, Madurai district, a biodiversity heritage site.
About Arittapatti
Arittapatti village, rich in ecological and historical significance, houses around 250 species of birds including three important raptors -birds of prey, namely the Laggar Falcon, the Shaheen Falcon and Bonelli’s Eagle.
It is also home to wildlife such as the Indian Pangolin, Slender Loris and pythons.
The biodiversity-rich area is surrounded by a chain of seven hillocks or inselbergs that serve as a watershed, charging 72 lakes, 200 natural springs and three check dams.
The Anaikondan tank, built during the reign of Pandiyan kings in the 16th century is one among them, the government notification said.
Several megalithic structures, rock-cut temples, Tamil Brahmi inscriptions and Jain beds add to the historical significance of the region.
What is a Biodiversity Heritage Site (BHS)?
Biodiversity Heritage Sites are rich Biodiversity Areas and are important components of local ecosystems which are being conserved and managed by the society.
BHS are declared as per provision under Section 37(1) of Biological Diversity Act, 2002.
The State Government may, from time to time in consultation with the local bodies, notify the areas of biodiversity importance as biodiversity heritage sites under this Act.

Prelims level: Sahel Region
Mains level: NA
French President Emmanuel Macron announced the end of the decade-long Operation Barkhane in Africa’s Sahel Region.
Note the nations falling in Sahel Region.
Sahel Region
The Sahel is the ecoclimatic and biogeographic realm of transition in Africa between the Sahara to the north and the Sudanian savanna to the south.
Having a semi-arid climate, it stretches across the south-central latitudes of Northern Africa between the Atlantic Ocean and the Red Sea.
The name is derived from the Arabic term for “coast, shore”; this is explained as being used in a figurative sense in reference to the southern edge of the vast Sahara.
The Sahel part includes from west to east parts of northern Senegal, southern Mauritania, central Mali, northern Burkina Faso, the extreme south of Algeria, Niger, the extreme north of Nigeria, the extreme north of Cameroon and the Central African Republic, central Chad, central and southern Sudan, the extreme north of South Sudan, Eritrea and the extreme north of Ethiopia.
What is Operation Barkhane?
France began its military operations in Sahel in January 2013.
Titled Operation Serval, it was limited to targeting Islamic extremists linked to al-Qaeda who took control of northern Mali.
However, in 2014, the mission was scaled up, renamed Operation Barkhane and was aimed at counter-terrorism.
The objective was to assist local armed forces to prevent the resurgence of non-state armed groups across the Sahel region.
Around 4,500 French personnel were deployed with the local joint counter-terrorism force.
