Back2Basics: Coral Reefs and Coral Bleaching
Corals are marine invertebrates that form colonies of polyps, which multiply and create reef structures.
Hard corals extract calcium carbonate to build hard exoskeletons, while soft corals add their skeletons to create coral reefs.
Corals have a mutually beneficial relationship with single-celled algae called zooxanthellae.
The zooxanthellae provide food and nutrients through photosynthesis, while corals provide a home and essential nutrients.
The zooxanthellae give corals their vibrant colors.
Understanding Coral Bleaching
Causes of Bleaching: Environmental stressors like temperature changes, pollution, and high ocean acidity lead to coral bleaching.
Bleaching Process: Stressed corals expel the zooxanthellae, revealing their pale exoskeletons and disrupting the symbiotic relationship.
Impacts of Bleaching: Severe and prolonged bleaching events can result in coral death and the loss of biodiversity.
Climate Change’s Impact on Coral Reefs
Warming Seas: Rising carbon emissions and greenhouse gases have caused increased global warming, resulting in warmer ocean temperatures.
Mass Bleaching: The frequency and intensity of mass bleaching events have risen in recent decades due to climate change.
Projections: Even with greenhouse gas reduction efforts, temperatures are expected to rise by 1.5°C to 2°C by the end of the century.
Significance of Coral Reefs
Biodiversity Hotspots: Coral reefs support over 25% of marine biodiversity despite covering only 1% of the seafloor.
Economic Value: Reefs contribute $2.7 trillion annually through trade, tourism, and employment opportunities.
Environmental Protection: Coral reefs provide habitat and serve as a natural defense against storm waves.
Regeneration Potential: Dead reefs can recover if sufficient fish species graze on the weeds that settle on dead corals, although the process takes several years.

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.

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.

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.
From UPSC perspective, the following things are important :
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.

Prelims level: Kherson from mapping perspective
Mains level: Russia's retreat in Ukraine
Ukraine’s defence and intelligence unit has reported on the withdrawal of Russian troops from Kherson but predicts it to be a delusion for a retreat.
Where is Kherson?
Geographically, Kherson is a strategic location for Russia and Ukraine.
Situated in the northwest of the Dnipro River, the province shares borders with Donetsk, Crimea and the Black Sea.
Why is it important for Russia?
With Moscow capturing Crimea in 2014, the occupation of Kherson in March 2022 has benefited Russia in transferring its military from Crimea to counter Ukraine.
It provides access to Odesa and Black Sea ports in the west and serves as the main route to secure southern Ukraine.
Implications of regaining for Ukraine
For Ukraine, regaining Kherson is significant to protect its population in Kalanchak and Chaplynka districts and also to recapture Crimea.
Kherson is also an important agricultural region, with irrigation channels.
How did Kherson come under Russia’s control?
In early March 2022, Kherson was captured by Russia through intense fighting.
The battle of Kherson proved to be the starting point to capturing and occupying the southern part of Ukraine while the battles for Kharkiv and Kyiv in the north progressed.
Russia’s hold over Kherson since March 2022 enabled Moscow to capture the key port cities — Mariupol in the Sea Azov, and Odesa, thus expanding control.
Kherson’s irrigation canals were used as defence positions, creating a strong line preventing Ukraine’s counter-attacks.
Russia also had positioned its soldiers in Kherson and stockpiled the ammunition.
Why has Moscow announced its withdrawal from Kherson?
Mobilisation failure: When Russia was advancing rapidly in capturing the southern and northern cities of Ukraine, its military personnel and weapon systems started to run thin.
Unexperienced troops: The failure of new recruits added an additional challenge to Russia to keep its hold against the Ukraine counter-offensive in Kherson.
Inability of Russia to govern Kherson: Despite imposing martial law, Russia could not effectively rule Kherson; the three-level security in the occupied areas could not enforce Russia’s control on the ground.
Ukraine’s expanding counter-offensive: Until August, Ukraine was supplied only with short-range and low-grade weapons by the West. On the other hand, Russia has been facing challenges in augmenting its military hardware on the battleground.
Is the withdrawal final, or a tactical move by Russia?
Ukraine is advancing: Russia’s new mobilisation has failed to stop the advancing of Ukraine forces.
Russia is weakening: The challenges to remobilise its defence systems and the shortage of weapons must have played a role in Russia’s withdrawal.
Inevitable western intervention: With Ukraine strengthening its military capacity through support from the west, upgrading from land-based to air-based to heavy battle tanks, Russia is facing a challenge to hold its occupied territories in Ukraine.
Conclusion
Withdrawal from Kherson exposes a serious gap in Russia’s strategy to hold southern Ukraine.
However, it also underlines its strategy — to withdraw under serious attack or resistance by the Ukrainian forces — as it happened in Kyiv and Kharkiv.

Prelims level: Khangkhui Cave
Mains level: NA
A colony of bats was evicted from a Khangkhui Mangsor cave system in Manipur with a Palaeolithic past to make it tourist-friendly.
Khangkhui Mangsor
The Khangkhui, locally called Khangkhui Mangsor, is a natural limestone cave about 15 km from Ukhrul, the headquarters of Ukhrul district.
Excavations carried out by Manipur’s archaeologists had revealed the cave was home to Stone Age communities.
The cave was also used as a shelter by the local people during the Second World War after the Japanese forces advanced to Manipur and the adjoining Nagaland.
Why in news?
The cave housed large roosting populations of bats belonging to the Rhinolophidae and Hipposideridae families.
They were however killed and evicted from the Khangkhui cave after 2016-17 purportedly to make it more tourist-friendly.
Do you know?
The longest is Krem Liat Prah in the Jaintia Hills, which is 30.957 km long. The word “Krem” means cave in the local Khasi language

Prelims level: Lothal, Indus Valley Civilization
Mains level: Heritage tourism
Prime Minister has reviewed the construction of the National Maritime Heritage Complex (NMHC) site at Gujarat’s Lothal via video conferencing.
Where is Lothal?
Lothal was one of the southernmost sites of the Indus Valley civilization, located in the Bhal region of what is now the state of Gujarat.
The port city is believed to have been built in 2,200 BC. Lothal was a thriving trade centre in ancient times, with its trade of beads, gems and ornaments reaching West Asia and Africa.
The meaning of Lothal (a combination of Loth and (s) thal) in Gujarati is “the mound of the dead”.
Incidentally, the name of the city of Mohenjo-daro (also part of the Indus Valley Civilisation, now in Pakistan) means the same in Sindhi.
In the region, it can be compared with other Indus port towns of Balakot (Pakistan), Khirasa (in Gujarat’s Kutch) and Kuntasi (in Rajkot).
When was it discovered?
Indian archaeologists started the search for cities of the Harappan Civilisation post-1947 in Gujarat’s Saurashtra.
Archaeologist SR Rao led the team which discovered a number of Harappan sites at the time, including the port city of Lothal.
Excavation work was carried out in Lothal between February 1955 and May 1960.
Adjacent to the excavated areas stands the archaeological site museum, where some of the most prominent collections of Indus-era antiquities in India are displayed.
How was it identified as port city?
The National Institute of Oceanography in Goa discovered marine microfossils and salt, gypsum crystals at the site, indicating that sea water once filled the structure and it was definitely a dockyard.
It had the world’s earliest known dock, connecting the city to an ancient course of the Sabarmati river.
A metropolis with an upper and a lower town had in on its northern side a basin with vertical wall, inlet and outlet channels which has been identified as a tidal dockyard.
Satellite images show that the river channel, now dried, would have brought in considerable volume of water during high tide, which would have filled the basin and facilitated sailing of boats upstream.
What heritage value does it hold?
Lothal was nominated in April 2014 as a UNESCO World Heritage Site, and its application is pending on the tentative list of UNESCO.
It is the only port-town of the Indus Valley Civilisation.
Its heritage value is comparable to following ancient port-towns around the world-
Xel Ha (Peru)
Ostia (Port of Rome)
Carthage (Port of Tunis) in Italy
Hepu in China,
Canopus in Egypt
Gabel (Byblos of the Phoenicians),
Jaffa in Israel,
Ur in Mesopotamia
Hoi An in Vietnam
Building up of Heritage Complex
The project began in March 2022, and is being developed at a cost of Rs 3,500 crore.
It will have several innovative features such as Lothal mini-recreation, which will recreate Harappan architecture and lifestyle through immersive technology.
It has four theme parks – Memorial theme park, Maritime and Navy theme park, Climate theme park, and Adventure and Amusement theme park.

Prelims level: Ranipur Tiger Reserve
Mains level: Not Much
The UP cabinet approved the notification of Ranipur Tiger Reserve under Section 38(v) of the Wild life (Protection) Act of 1972.
About Ranipur WS
Ranipur WS, was founded in 1977, is one of the attractions of Chitrakoot district in Uttar Pradesh.
It is spread over 230 sq.km and is noted for its diverse wildlife, but is not very frequently visited by tourists because of the difficult access.
The Ranipur TR has tropical dry deciduous forests and is home to fauna such as tigers, leopards, sloth bears, spotted deer, sambhar, chinkara and a number of birds and reptiles, the statement added.
The Ranipur TR will be the fourth in UP, after Dudhwa, Pilibhit and Amangarh (buffer of Corbett Tiger Reserve).
It will also be the first in the state’s portion of the Bundelkhand region, which it shares with neighbouring Madhya Pradesh.
Why make it a tiger reserve?
RWS has no tigers of its own.
But pugmarks of the animals are frequently seen there as tigers from nearby Panna frequent it.
From UPSC perspective, the following things are important :
Prelims level: Ram Setu
Mains level: NA
A movie has once again generated buzz around the chain of shoals off the southeast coast of India that many believe is the Ram Setu or the bridge to Lanka mentioned in the Ramayana.
The Ram Setu
The Ram Setu, also known as Adam’s Bridge, is a 48-km chain of limestone shoals between Rameswaram on India’s southeast coast and Mannar Island near Sri Lanka’s northwest coast.
The structure has significance in both Hindu and Muslim mythology – while Hindus believe this is the bridge (Setu) built by Lord Ram and his army to cross to Lanka and fight Ravan.
As per Islamic legend, Adam used this bridge to reach Adam’s Peak in Sri Lanka, where he stood on one foot for 1,000 years in repentance.
Factual details of the bridge
Scientists believe Ram Setu is a natural structure formed due to tectonic movements and sand getting trapped in corals.
However, over the years, evidence has been offered to claim that the bridge is man-made.
The bridge is not entirely natural, Hindu right wing outfits argue, which proves that it was indeed built by Lord Ram.
When was the structure came into highlights?
The Ram Setu issue snowballed into a major controversy when the Sethusamudram Project, flagged off during the UPA I government.
The project aimed to reduce travel time between the eastern and western coasts of India, as ships would no longer have to circle Sri Lanka to travel between the Bay of Bengal and Arabian Sea.
The project was perceived as an attack on Hindu sentiments.
Various studies have been proposed on the Ram Setu, with the most recent being in 2021, when the government approved an underwater research project to ascertain its origins.
Ecological arguments against the project
The Sethusamudram project has been opposed on environmental grounds.
Some claims that it will harm marine life, and that dredging of the line of shoals will make India’s coast more vulnerable to tsunamis.
In March 2018, the Centre told the Supreme Court that the Ram Setu will not be affected in the execution of the Sethusamudram Shipping Canal project.
NASA images, and other proofs
Images of the Ram Setu clicked by NASA have been used over and over again to claim that this proves the existence of a man-made bridge.
NASA has repeatedly clarified that it does not agree with these claims.
Remote sensing images or photographs from orbit cannot provide direct information about the origin or age of a chain of islands.
It certainly cannot be determined whether humans were involved in producing any of the patterns seen.
