Prelims level: Leang Sakapao Caves
Mains level: Not Much
Researchers have reported that Pleistocene-era rock paintings dating back to 45,000-20,000 years ago in cave sites in southern Sulawesi, on the Indonesian island of Sulawesi, are weathering at an alarming rate.
Have you ever found the mention of ‘Altamira Caves’ in your NCERTs?
Leang Sakapao Caves
- This cave art of Sulawesi is much older than the prehistoric cave art of Europe.
- The artwork in the area includes what is believed to be the world’s oldest hand stencil (almost 40,000 years ago), created by pressing the hand on a cave wall and spraying wet red-mulberry pigments over it.
- A nearby cave features the world’s oldest depiction of an animal, a warty pig painted on the wall 45,500 years ago.
Impact of climate change
- The artwork made with pigments was decaying due to a process known as haloclasty, which is triggered by the growth of salt crystals due to repeated changes in temperature and humidity.
- This is caused by alternating wet and dry weather in the region.
- Indonesia has also experienced several natural disasters in recent years, which have quickened the process of deterioration.

Iran gave the Farzad B gas field to a domestic gas producer in a setback move to India.
Farzad B Gas Field
- Farzad-B is an off-shore natural gas field 20 kilometres off Farsi Island in Iran.
- The gas field was discovered in 2008 by a consortium of three Indian companies, led by the state-owned ONGC Videsh with a 40% stake; the other companies were Indian Oil Corporation (40%) and Oil India (20%).
Deal soured after US sanctions
- Negotiations between the consortium and the National Iranian Oil Company (NIOC) to develop the gas field stalled due to secondary sanctions against Iran by the US and the European Union in the early 2010s.
- Following the lifting of sanctions after the Joint Comprehensive Plan of Action was signed in July 2015 the consortium was close to an agreement to invest $US5 billion to develop the gas field.
- After the United States withdrawal from the JCPOA in May 2018, and the reinstatement of U.S. sanctions against Iran, the negotiations between the consortium and NIOC broke down.
Consider the question “Balancing the contrasts has been the basis of India’s relations with Iran. Comment.”

Mains level: Paper 3- EAC allows Great Nicobar plan to advance
About the Great Nicobar plan
- The Environment Appraisal Committee (EAC) – Infrastructure I of the Ministry of Environment, Forest and Climate Change (MoEFCC) has flagged serious concerns about NITI Aayog’s ambitious project for Great Nicobar Island.
- The EAC was responding to ‘pre-feasibility’ report, ‘Holistic Development of Great Nicobar Island at Andaman and Nicobar Islands’.
- The report is prepared for the NITI Aayog by the Gurugram-based consulting agency.
- The proposal includes an international container transshipment terminal, a greenfield international airport, a power plant and a township complex spread over 166 sq. km. and is estimated to cost ₹75,000 crore.
- The committee has, however, removed the first hurdle faced by the project.
- It has recommended it “for grant of terms of reference (TOR)” for Environmental Impact Assessment (EIA) studies, which in the first instance will include baseline studies over three months.
What the EAC said
- The committee noted that the site selection for the port had been done mainly on technical and financial criteria, ignoring the environmental aspects.
- It has now asked for an independent study/ evaluation for the suitability of the proposed port site with specific focus on Leatherback Turtle, Nicobar Magapode and Dugong.
- It highlighted the need for an independent assessment of terrestrial and marine biodiversity, a study on the impact of dredging, reclamation and port operations, including oil spills.
- It has also highlighted the need for studies of alternative sites for the port with a focus on environmental and ecological impact, analysis of risk-handling capabilities, a seismic and tsunami hazard map, a disaster management plan, an assessment of the cumulative impact, and a hydro-geological study to assess impact on round and surface water regimes.
- The committee has also asked for details of the corporate environment policy of the implementing agency — whether the company has an environment policy, a prescribed standard operating procedure to deal with environmental and forest violations, and a compliance management system.

Mains level: Paper 3- Mass nesting of Olive Ridley turtles
No mass nesting this year
- The annual spectacle of the mass nesting of millions of Olive Ridley sea turtles near the Rushikulya river mouth in Odisha is likely to be missed this year, as the time for it is almost over.
- It’s been around one month since the mass nesting of last year.
- If they do skip the beach, this won’t be the first time.
- In 2002, 2007, 2016 and 2019, the turtles had not shown up at Rushikulya.
- The Rushikulya river mouth is considered the second-biggest rookery in India after Gahirmatha.
- Mass nesting in the Gahirmatha marine sanctuary occurred from March 9-23, 2021 and over 349,000 eggs were laid during this period.
What could explain the miss in mass nesting
- It is a natural phenomenon. During some years, they did not turn up for mass nesting even though a huge number had congregated in the sea.
- Beach erosion might be one of the causes for the turtles staying away this year.

Prelims level: Chenab Arch Bridge
Mains level: Not Much
A half-a-kilometre long arch, the defining feature of the world’s highest railway bridge over river Chenab, is set to be completed today.
Chenab Arch Bridge
- The bridge is part of an ambitious 272-km rail link project and is being constructed by the Northern Railway at an estimated cost of ₹28,000 crores.
- The bridge will be able to withstand earthquakes with a magnitude of up to eight and high-intensity blasts.
- The bridge, which will include a 14-metre dual carriageway and a 1.2-metre-wide central verge, will have a design speed of around 100 kilometres per hour with a lifespan of 120 years.
Its inception
- The preparations of the rail link began in 2002 and the initial plan was to connect Kashmir’s northernmost city Baramulla to New Delhi.
- Work on the bridge started again in July 2017 with the aim of completing the construction by the end of 2019 but due to contractual issues in 2018, it was delayed.
- Steel was specifically chosen for the construction of the bridge as it will make the project more economical.
- The metal will also be able to resist temperatures of minus 20 degree Celsius and wind speeds of above 200 kilometres per hour.
Significance
- A railway bridge like this, with this kind of geography, has not been made anywhere in the world, according to the Railways.
- It will symbolise the Kashmir rail link, to be ready for at least a century.
- In other words, a train from Kanyakumari can reach all the way to Kashmir uninterrupted.
- The cable crane that will do the job of completing the arch itself measures around 900 meters and is said to be the longest in the world, made especially for this project.

Prelims level: GVD
Mains level: Paper 3- Baikal Gigaton Volume detector
Russian scientists have launched one of the world’s biggest underwater neutrino telescopes called the Baikal-GVD (Gigaton Volume Detector) in the waters of Lake Baikail, the world’s deepest lake situated in Siberia.
Try this PYQ from CSP 2020:
Q. The experiment will employ a trio of spacecraft flying in formation in the shape of equilateral triangle that has sides one million km long, with lasers shining between the craft.” the experiment in the question refers to?
(a) Voyager-2
(b) New horizons
(c) LISA pathfinder
(d) Evolved LISA
Baikal GVD
- The Baikal-GVD is one of the three largest neutrino detectors in the world along with the IceCube at the South Pole and ANTARES in the Mediterranean Sea.
- The construction of this telescope, which started in 2016, is motivated by the mission to study in detail the elusive fundamental particles called neutrinos and to possibly determine their sources.
- It will help understanding the origins of the universe since some neutrinos were formed during the Big Bang while others continue to be formed as a result of supernova explosions or because of nuclear reactions in the Sun.
- An underwater telescope such as the GVD is designed to detect high-energy neutrinos that may have come from the Earth’s core, or could have been produced during nuclear reactions in the Sun.
What are fundamental particles?
- So far, the understanding is that the universe is made of some fundamental particles that are indivisible.
- Broadly, particles of matter that scientists know about as of now can be classified into quarks and leptons.
- Explorations has led to the discovery of over 12 such quarks and leptons, but three of these (protons, neutrons and electrons) is what everything in the world is made up of.
- Protons (carry a positive charge) and neutrons (no charge) are types of quarks, whereas electrons (carry a negative charge) are types of leptons.
- These three particles make what is referred to as the building block of life– the atom.
Why do scientists study fundamental particles?
- Studying what humans and everything around them is made up of gives scientists a window into understanding the universe a better way.
- This is one reason why scientists are so keen on studying neutrinos (not the same as neutrons), which are also a type of fundamental particle.
- Fundamental means that neutrinos, like electrons, protons and neutrons cannot be broken down further into smaller particles.
So where do neutrinos fit in?
- What makes neutrinos especially interesting is that they are abundant in nature, with about a thousand trillion of them passing through a human body every second.
- In fact, they are the second most abundant particles, after photons, which are particles of light.
- But while neutrinos are abundant, they are not easy to catch, this is because they do not carry a charge, as a result of which they do not interact with matter.
- One way of detecting neutrinos is in water or ice, where neutrinos leave a flash of light or a line of bubbles when they interact.
- To capture these signs, scientists have to build large detectors.
Back2Basics: Lake Baikal
- Lake Baikal is a rift lake located in southern Siberia, Russia, between Irkutsk Oblast to the northwest and the Buryat Republic to the southeast.
- It is the largest freshwater lake by volume in the world, containing 22 to 23% of the world’s fresh surface water.
- With a maximum depth of 1,642 m it is the world’s deepest lake.
- It is among the world’s clearest lakes and is the world’s oldest lake, at 25–30 million years. It is the seventh-largest lake in the world by surface area.
- Lake Baikal formed as an ancient rift valley and has a long, crescent shape, with a surface area of 31,722 km2 (12,248 sq mi), slightly larger than Belgium.
- The region to the east of Lake Baikal is referred to as Transbaikalia or as the Transbaikal and the loosely defined region around the lake itself is sometimes known as Baikalia.
- UNESCO declared Lake Baikal a World Heritage Site in 1996.

Prelims level: Whitsun Reef
Mains level: South China Sea Row
China’s aggressive expansion in the South China Sea has found a new ground, Whitsun Reef, where 220 Chinese vessels are currently anchored under the Philippines’ Exclusive Economic Zones (EEZ).
Once again, the South China Sea finds itself closer to becoming a security flashpoint amidst rising concerns over a military conflict.
Also, try this:
Q.Recently, Senkaku Island was in the news. Where is it located?
a) South China Sea
b) Indian Ocean
c) East China sea
d) Red sea
Whitsun Reef
- Whitsun Reef is a reef at the northeast extreme limit of the Union Banks in the Spratly Islands of the West Philippine Sea.
- It is the largest reef of the Union Banks.
- The reef is V-shaped with an area of about 10 sq. km.
- Until at least the 1990s it was submerged most of the time and was visible above the water only during the low tide, at other times the reef could be detected due to the pattern of breaking waves.
- At the end of the 20th-century small sand dunes had developed on the reef making a territorial claim possible (an International Court of Justice judgment in 2012 stated that “low-tide elevations cannot be appropriated”).
- The development of the dunes could have occurred naturally, but the rumours had it that the island was being built up by Vietnam and China.
Territorial disputes
- As of 2016, the reef was unclaimed, the reports to the contrary (Chinese control) were based on confusion.
- However, due to the reef’s strategic importance, it was expected that the reef would be occupied “soon”.
- On 21 March 2021, about 220 Chinese fishing ships were moored at the reef ostensibly taking shelter due to the sea conditions.
Why is the Philippines concerned?
- The Philippines considers the reef to be a part of its exclusive economic zone and continental shelf and protested the Chinese presence.
- Currently, Philippine military aircraft and navy are monitoring the situation daily, and China has been warned that there will be an increased military presence to conduct ‘sovereignty patrols’.
- If China is successful with its moves, the Philippines may lose another fishing ground, similar to what happened in 2012 when China took control of Scarborough Shoal.
The larger dispute
- China and the Philippines, along with other Southeast Asian countries, have long been part of disputes over sovereign claims over the region’s islands, reefs and seabeds.
- A third of the world’s maritime trade travels through the South China Sea annually.
- The seabeds here are believed to be reserves of oil and natural gas while being home to fisheries essential for the food security of millions in South Asia.
- The majority of the disputes concern the lack of adherence to the international ‘Exclusive Economic Zones’ which stretch up to 200 nautical miles from the coast of any state.
- China, especially, has been notorious for disregarding the law on various occasions.
What does China have to say?
- On the present matter, the Chinese have reiterated that the vessels are mere fishing boats seeking shelter from unruly weather, though no bad weather has been reported in the area.
- It is also unlikely that fishermen would have the financial capital to remain stationary for weeks on end.
- Experts say through their present occupation, China might be looking to create a civilian base on the reef, an artificial island or even just control the airspace.
- It is widely assessed that Philippines’s soft approach has further strengthened China’s ambitions in the South China Sea.
Back2Basics: South China Sea Row
- It is a dispute over territory and sovereignty over ocean areas, and the Paracels and the Spratlys – two island chains claimed in whole or in part by a number of countries.
- China, Vietnam, the Philippines, Taiwan, Malaysia and Brunei all have competing claims.
- Alongside the fully-fledged islands, there are dozens of rocky outcrops, atolls, sandbanks and reefs, such as the Scarborough Shoal.
- China claims by far the largest portion of territory – an area defined by the “nine-dash line” which stretches hundreds of miles south and east from its most southerly province of Hainan.
- Beijing says its right to the area goes back centuries to when the Paracel and Spratly island chains were regarded as integral parts of the Chinese nation, and in 1947 it issued a map detailing its claims.
- It showed the two island groups falling entirely within its territory. Those claims are mirrored by Taiwan.
Spat over Chinese claims
- China has backed its expansive claims with island-building and naval patrols.
- The US says it does not take sides in territorial disputes but has sent military ships and planes near disputed islands, calling them “freedom of navigation” operations to ensure access to key shipping and air routes.
- Both sides have accused each other of “militarizing” the South China Sea.
- There are fears that the area is becoming a flashpoint, with potentially serious global consequences.

Rs 1050 crore fund! See how rich even the Municipal Corporations in India are!
Sabarmati Riverfront Development Project
- The SRDP is an environmental improvement, social uplift and urban rejuvenation project that will renew Ahmedabad.
- The project is being developed by the Sabarmati Riverfront Development Corporation Ltd. (SRFDCL), a company wholly owned by the Ahmedabad Municipal Corporation.
- The project will reclaim approximately 200 hectares of land from the riverbed.
- To reclaim the land, protect low lying developments from floods, and prevent erosion of the river banks, retaining walls have been built on both sides of the river.
- Since Sabarmati is a seasonal river, water is channelled into the river from the Narmada canal, which intersects the river upstream from Ahmedabad and is retained in the river using the Vasna Barrage which is located downstream.
Significance of the project
- The reclaimed land will make Ahmadabad’s riverfront, a public asset.
- The project will provide Ahmedabad with 11.5 km long pedestrian promenades at the water’s edge along both the banks of the river.
- In addition, many new public facilities will be built on the reclaimed land: cultural centres, museums, sports facilities, trade fair grounds and open-air markets.
- A small portion of the reclaimed land will be sold for private commercial and residential developments.
- The project has won Prime Minister’s National Award for Excellence in Urban Planning and Design in the year of 2003.

From UPSC perspective, the following things are important :
Prelims level: Map marking of these countries
Mains level: Issues in Africa
In a move that is set to further undermine stability in East Africa, Kenya has said that it will not take part in proceedings of the International Court of Justice (ICJ) over its maritime border dispute with neighbouring Somalia.
Can you recall the terms like “Scramble for Africa”, “Paper Partition of Africa”? If yes, then you know very well the malady of the present-day Continent of Africa.
What is the news?
- Nairobi has accused the top UN body of bias.
- The move comes after Somalia’s decision to sever diplomatic relations with Kenya in December after it accused Nairobi of meddling in its internal affairs.
- The maritime dispute is said to form a crucial part of the diplomatic quarrel between the two countries.
The disputed area
- The main point of disagreement between the two neighbours is the direction in which their maritime boundary in the Indian Ocean should extend.
- According to Somalia, the sea border should be an extension of the same direction in which their land border runs as it approaches the Indian Ocean, i.e. towards the southeast.
- Kenya, on the other hand, argues that the territorial southeast border should take a 45-degree turn as it reaches the sea, and then run in a latitudinal direction, i.e. parallel to the equator.
- Such an arrangement would be advantageous for Kenya, whose coastline of 536 km is more than 6 times smaller than Somalia’s (3,333 km).
Why is this area important?
- The triangular area thus created by the dispute is around 1.6 lakh sq km large and boasts of rich marine reserves.
- It is also believed to have oil and gas deposits.
- Both Somalia and Kenya have accused each other of auctioning off blocks from this area, Al Jazeera reported.
How have Kenya and Somalia tried to resolve the dispute?
- After negotiations to resolve the issue bilaterally failed, Somalia in 2014 asked the ICJ to adjudicate.
- Kenya resisted, arguing that the world court did not have jurisdiction to hear the case.
- In 2009 both countries had a commitment to settle the dispute out of court.
- However, in February 2017, the ICJ ruled that it did have the right to rule in the case, and in June 2019 said that it would begin public hearings.
- These hearings never took place, as Kenya successfully applied to have them postponed thrice– the last one being in June 2020, when it cited difficulties due to the Covid-19.

From UPSC perspective, the following things are important :
Prelims level: Iconic Archaeological sites
Mains level: Indus valley civilization
Rakhi Garhi is being developed as one of the five Identified Iconic Archaeological Sites, informed the Minister of Culture and Tourism.
Rakhi Garhi
- The ancient site of Rakhi-Khas and Rakhi-Shahpur are collectively known as Rakhigarhi, located on the right bank of the now dried up Palaeo-channel of Drishadvati.
- It is located in the Ghaggar-Hakra river plain in the Hissar district of Haryana.
- Seven mounds are located here.
- The site has yielded various stages of Harappan culture and is by far one of the largest Harappan sites in India.
- The site shows the sequential development of the Indus culture in the now dried up Saraswati basin.

Major findings at Rakhi Garhi
- Findings confirm both early and mature Harappan phases and include 4,600-year-old human skeletons, fortification and bricks.
- Digging so far reveals a well-planned city with 1.92 m wide roads, a bit wider than in Kalibangan.
- The pottery is similar to Kalibangan and Banawali.
- Pits surrounded by walls have been found, which are thought to be for sacrificial or some religious ceremonies.
- There are brick-lined drains to handle sewage from the houses.
- Terracotta statues, weights, bronze artefacts, comb, copper fish hooks, needles and terracotta seals have also been found.
- A bronze vessel has been found which is decorated with gold and silver.
- A granary belonging to the mature Harappan phase has been found here.
- Fire altars structures were revealed in Rakhigarhi.
Back2Basics: Five Iconic Archaeological Sites
The government has proposed to develop five archaeological sites as “iconic sites” with onsite museums in Rakhigarhi (Haryana), Hastinapur (Uttar Pradesh), Sivsagar (Assam), Dholavira (Gujarat) and Adichanallur (Tamil Nadu) in the Union Budget 2020-21.
(1) Rakhigarhi
*discussed above*
(2) Hastinapur
Hastinapur in the Meerut district of Uttar Pradesh finds mention in the Mahabharata and the Puranas. One of the most significant discoveries made at this site was of the “new ceramic industry”, which was named the Painted Grey Ware, which as per the report represented the relics of the early Indo-Aryans.
(3) Sivasagar
In Sivasagar (Assam), excavations at the Karenghar (Talatalghar) complex between 2000 and 2003 led to the discovery of buried structures in the north-western and north-eastern side of the complex. Among the structural remains found at the site were ceramic assemblages including vases, vessels, dishes, and bowls, etc. Terracotta smoking pipes were also found.
(4) Dholavira
Dholavira in Gujarat is located in the Khadir island of the Rann of Kutch, and like Rakhigarhi is one of the sites where the remains of the Harappan civilization have been found. It is unique because the remains of a complete water system have been found here.
(5) Adichnallur
Adichnallur lies in the Thoothukudi district of Tamil Nadu. The urn-burial site was first brought to light during a “haphazard excavation” by a German archaeologist in 1876. Following this, an Englishman Alexander Rae excavated the site between 1889 and 1905.

From UPSC perspective, the following things are important :
Prelims level: Mission SAGAR
Mains level: Not Much
As part of Mission Sagar-IV, Indian Naval Ship Jalashwa has arrived at Port Anjouan, Comoros to deliver 1,000 Metric Tonnes of rice.
Mission SAGAR, unlike other missions, can create confusion with the name and its purpose. It is not a military exercise. Make note of such special cases. UPSC can ask such questions as one-liner MCQs.
Also note the location of the island country Comoros and its geostrategic significance.
Mission Sagar
- SAGAR is a term coined by PM Modi in 2015 during his Mauritius visit with a focus on the blue economy.
- It is a maritime initiative that gives priority to the Indian Ocean region for ensuring peace, stability and prosperity of India in the Indian Ocean region.
- The goal is to seek a climate of trust and transparency; respect for international maritime rules and norms by all countries; sensitivity to each other`s interests; peaceful resolution of maritime issues; and an increase in maritime cooperation.
- It is in line with the principles of the Indian Ocean Rim Association.
Earlier such missions
- This is the second visit of an Indian Navy ship to the island country within a span of one year.
- Earlier, as part of Mission Sagar-I, in May-June 2020, the Indian Navy had delivered essential medicines to the nation.
- Mission Sagar-II was undertaken in May-June 2020, wherein India reached out to Maldives, Mauritius, Seychelles, Madagascar and Comoros, and provided food aid and medicines.
- Sagar-III was undertaken in Sihanoukville Port, Cambodia.

From UPSC perspective, the following things are important :
Prelims level: Ramagundam Solar Plant
Mains level: Not Much
The country’s biggest floating solar power plant, by generation capacity at Ramagundam in Peddapalli district of Telangana is set to be commissioned by May-June.
Try this PYQ:
With reference to technologies for solar power production, consider the following statements :
- ‘Photovoltaics’ is a technology that generates electricity by direct conversion of light into electricity, while ‘Solar Thermal’ is a technology that utilizes the Sun’s rays to generate heat which is further used in electricity generation process.
- Photovoltaics generate Alternating Current (AC), while Solar Thermal generates Direct Current (DC).
- India has manufacturing base for Solar Thermal technology, but not for Photovoltaics.
Which of the statements given above is/are correct?
(a) 1 only
(b) 2 and 3 only
(c) 1, 2 and 3
(d) None
Ramagundam Solar Plant
- It would be one of the renewable (solar) energy plants being developed by NTPC with an installed capacity of 447MW in the Southern Region and the entire capacity would be commissioned by March 2023.
- It will be spread over 450 acres of water surface area in the reservoir.
- It will be the single location largest floating solar plant in the country as of now; 92 MW floating unit at Kayamkulam gas plant in Kerala and a 25 MW unit at Simhadri power plant.
- In addition, we are setting up a 230 MW ground-mounted solar power plant in Ettayapuram near Tuticorin in Tamil Nadu
Why floating solar?
- One of the biggest advantages of floating solar panels is that the installations do not require valuable land space.
- Many of these installations can take up unused space on bodies of water, such as hydroelectric dam reservoirs, wastewater treatment ponds, or drinking water reservoirs.
- Additionally, installing solar panels out on open water reduces the need for tree removal and forest clearing, a practice used in the case of some larger solar panel installations.
- The bodies of water that host floating solar arrays help cool down the solar equipment, which means the panels produce electricity at higher efficiencies in hot climates than they might otherwise.
- The floating solar panel structure shades the body of water and reduces evaporation from these ponds, reservoirs, and lakes.
- This is a particularly useful benefit in areas susceptible to drought, as water loss to evaporation can add up over time and contribute to a shortage.
