1.Context

 
Underlining that India can play a “constructive role” in the region, visiting Iranian Foreign Minister Seyed Abbas Araghchi Friday described his country’s Chabahar port a “golden gateway” and a “symbol of cooperation”, expressing the hope that India will continue to develop the strategic port.
 
 

2.What is the strategic significance of Chabahar port?

 
  • The Chabahar Port has become one of the most strategically important foreign infrastructure projects for India because it serves economic, geopolitical, and security objectives simultaneously.
  • Located on Iran’s southeastern coast along the Gulf of Oman, the port lies very close to the Arabian Sea and outside the narrow Strait of Hormuz, through which a major portion of the world’s oil trade passes. Its location itself gives the port enormous strategic value.
  • For India, the biggest importance of Chabahar is that it provides direct access to Afghanistan and Central Asia without depending on Pakistan. Normally, India’s land access to Afghanistan is blocked because Pakistan does not allow Indian goods to pass through its territory.
  • Due to this restriction, India faced major difficulties in expanding trade and connectivity with Afghanistan and the resource-rich Central Asian region. Chabahar changes this situation.
  • Goods from India can reach Chabahar by sea and then move through road and rail networks into Afghanistan and beyond. This gives India an independent trade and transit route into Eurasia.
  • The port also has strong geopolitical significance because it acts as a counterbalance to China’s growing influence in the Indian Ocean region. China has heavily invested in Gwadar Port in Pakistan under the China-Pakistan Economic Corridor (CPEC), which is part of China’s Belt and Road Initiative (BRI).
  • Gwadar is located only a short distance from Chabahar. By developing Chabahar, India seeks to maintain its strategic presence in the region and prevent complete Chinese dominance over key maritime trade routes around the Arabian Sea.
  • Another major aspect of Chabahar’s importance is its role in the International North-South Transport Corridor (INSTC). This corridor aims to connect India with Iran, Central Asia, Russia, and Europe through a combination of sea, rail, and road routes.
  • The corridor can significantly reduce transportation costs and time compared to traditional routes passing through the Suez Canal. Therefore, Chabahar is not merely a port; it is a gateway connecting South Asia with Eurasia.
  • The port is also important from the perspective of India’s relations with Afghanistan. India has used Chabahar to send humanitarian assistance such as wheat and medicines to Afghanistan, especially during times of crisis.
  • This has helped India maintain goodwill and developmental engagement in Afghanistan even without direct land access.
  • From an energy security perspective, Chabahar helps India strengthen ties with Iran, which possesses vast oil and natural gas reserves.
  • It also improves India’s access to the energy-rich Central Asian region. In the long run, such connectivity can contribute to India’s energy diversification and trade security.
  • For Iran, Chabahar provides an opportunity to develop its underdeveloped southeastern region and reduce dependence on ports located inside the Strait of Hormuz. For Afghanistan, it offers an alternative trade route that reduces excessive dependence on Pakistan.
  • Despite its importance, the project faces several challenges. US sanctions on Iran have slowed investments and infrastructure development. Regional instability in West Asia and Afghanistan also creates uncertainty regarding connectivity projects.
  • However, India continues to view Chabahar as a long-term strategic investment because it strengthens India’s regional connectivity, enhances maritime influence, and supports its larger geopolitical objective of balancing China’s presence in the region.

3.What is the role of India in the development of the port?

 
  • India has played a central role in the development and modernization of Chabahar Port as part of its broader strategic and connectivity policy in West Asia and Central Asia. India’s involvement is not limited to financial investment alone; it includes infrastructure development, port operations, equipment supply, and regional connectivity planning.
  • India’s engagement with Chabahar began from the understanding that the country needed an alternative trade route to Afghanistan and Central Asia that bypassed Pakistan.
  • Since Pakistan denied India direct land access to Afghanistan, India looked toward Iran’s Chabahar Port as a strategic solution. Recognizing its importance, India and Iran gradually deepened cooperation on the project.
  • A major step came in 2016 when India, Iran, and Afghanistan signed the Trilateral Transit and Trade Agreement.
  • Under this agreement, India committed itself to developing the Shahid Beheshti terminal of Chabahar Port and improving connectivity infrastructure linking the port with Afghanistan.
  • This agreement transformed Chabahar into a regional connectivity project rather than just a bilateral initiative.
  • India has invested in the port through India Ports Global Limited (IPGL), a company formed by the Government of India for overseas port operations. India supplied cranes, cargo handling equipment, and other modern infrastructure required for port operations.
  • Indian assistance helped improve the port’s capacity to handle cargo and container traffic efficiently.
  • India also took responsibility for operating parts of the port. Through IPGL, India obtained the rights to equip and operate the Shahid Beheshti terminal.
  • This was significant because it marked one of India’s first major overseas port management projects. The arrangement strengthened India’s long-term strategic presence in the region.
  • Beyond the port itself, India has supported connectivity projects linked to Chabahar. India assisted in developing road connectivity from Chabahar to Afghanistan, particularly through the Zaranj-Delaram Highway in Afghanistan, which India constructed earlier.
  • This highway connects Afghanistan’s internal road network with routes leading toward Chabahar, enabling movement of goods from the Indian Ocean into Afghanistan.
  • India has already used the port for trade and humanitarian purposes. Several shipments of wheat, pulses, and humanitarian aid from India to Afghanistan were transported through Chabahar.
  • This demonstrated the practical utility of the port and reduced Afghanistan’s dependence on Pakistani transit routes.
  • India’s role is also strategic in nature. By participating in Chabahar’s development, India aims to strengthen its presence in the Indian Ocean region and counterbalance China’s growing influence through projects like Gwadar Port under the China-Pakistan Economic Corridor (CPEC). Chabahar allows India to maintain strategic access near the Arabian Sea and improve its connectivity with Eurasia.

4.Trilateral Agreement 

 
  • In 2016, Prime Minister Narendra Modi travelled to Tehran and signed the agreement to develop Chabahar port, as well as the trilateral agreement for trade through Chabahar with Afghanistan's President Ashraf Ghani.
  • Since the India Ports Global Chabahar Free Zone (IPGCFZ) authority took over the operations of the port in 2018.
  • It has handled 215 vessels, 16, 000 TEUs (Twenty-foot Equivalent Units) and four million tons of bulk and general cargo, the government said in Parliament last month.
 

5.Chabahar Route

  • In the last few years, a fourth strategic objective for the Chabahar route has appeared, with China's Belt and Road Initiative making inroads in the region.
  • The government hopes to provide Central Asia with an alternate route to the China-Pakistan Economic Corridor (CPEC) through Iran for Future Trade.
 
Mr Sonowal in his Speech at the Chabahar Day function said that it is India's vision to make the Shahid Beheshti port a transit hub and link it to the International North-South Trade Corridor (INSTC) that also connects to Russia and Europe.
 

6.Reasons for the delay

  • Since the beginning, the development of the Shahid Beheshti terminal in Chabahar, as well as surrounding infrastructure, has hit geopolitical roadblock after roadblock.
  • The biggest issue has been over Iran's relationship with western countries, especially the United States.
  • In years when Western sanctions against Iran increased and the Chabahar project has been put on the back-burner, while in the years when nuclear talks that resulted in the Joint Comprehensive Plan of Action (JCPOA) in 2015 came into being, the Chabahar port has been easier to work on.
  • In 2018, the U.S. Trump administration put paid to India's plans by walking out of the JCPOA and slapping new sanctions on dealing with Iran.
  • This led to the Modi Government "Zeroing out" all its oil imports from Iran, earlier a major supplier to India, causing a strain in ties.
  • Even though the U.S. made a special "carve-out" on sanctions for Chabahar.
  • On the ground, has been difficult to source equipment for the port construction from infrastructure companies that continue to fear secondary sanctions, as well as to engage in shipping and insurance companies for trade through Chabahar.

7.Ties with Taliban

  • The Modi Government also snapped ties with Afghanistan after the Taliban takeover in August 2021, which put an end to the Humanitarian aid of wheat and pulses that were being sent to Kabul via Chabahar.
  • When India restarted Wheat aid to Afghanistan this year, it negotiated with Pakistan to use the land route instead.
  • With the government now reopening the Indian Embassy in Kabul and Establishing ties with the Taliban government.
  • The Chabahar route may once again be employed, another reason for the recent flurry of activity at the Iranian port the terminal that India has pinned so many hopes on.

LIGHTNING

1. Context

More than 100 people died due to powerful thunderstorms that hit Uttar Pradesh earlier this week. The atmospheric phenomenon, called Andhi in meteorological literature, is a common annual phenomenon in the region, but the devastation this year is more widespread. The worst-hit district was Prayagraj, which reported 21 deaths, followed by Mirzapur (19) and Bhadohi (16).
Lightning strikes in India's Gujarat kill 24, more rains predicted |  Weather News | Al Jazeera

2. What is lightning and how does it occur?

  • Lightning is an electrical discharge that occurs when there is an imbalance between the storm clouds and the earth or even within the clouds.
  • Scientists believe that for lightning to occur, positive and negative charges must separate within a cloud.
  • This happens, according to the National Oceanic and Atmospheric Administration (NOAA), when the water droplets in the bottom part of the cloud are moved upwards, where the much colder atmosphere freezes them into small ice crystals. 
  • As these small ice crystals continue to go up, they gain more mass and eventually become so heavy that they start to fall down to earth.
  • This causes a system in which ice crystals going down collides with the water vapors coming up, leading to the accumulation of positive charges on the top of the cloud and negative changes gathering at the base, while the atmosphere between them in the cloud acts as an insulator.
  • When the positive and negative charges grow large enough, their strength overpowers the insulating properties of the properties.
  • As a result, the two kinds of changes meet with each other and produce lightning.
  • Although most of the lightning takes place within the clouds, sometimes it is directed towards Earth also. With the base of the cloud becoming negatively charged, positive charges start accumulating on tall objects, like trees, poles, and buildings.

3. Why is it a matter of concern?

  • Data from the National Crime Records Bureau show that since 2005, lightning has been responsible for at least 2,000 fatalities annually.
  • Rural areas account for more than 90% of lightning-related fatalities,
  • It is not considered a natural calamity, thus unlike in the case of floods or earthquakes, the afflicted people are not entitled to government compensation.

4. Where are the lightning hotspots around the world?

  • It has been discovered by scientists at the Smithsonian Tropical Research Institute (STRI) in Panama that lightning strikes the tropics more than 100 million times a year.
  • Asia, South America, North America, Australia, and Africa are the other continents having the highest concentration of lightning hotspots.
  • According to experts, lightning strikes are expected to rise by 25-50% as a result of climate change.

5. Findings of the latest study

  • The researchers analyzed 5,858 selected lightning-ignited fires based on satellite images of US wildfires between 1992 and 2018 and found that approximately 90 percent of them might have been started by "hot lightning" strikes.
  • Also known as long continuing current (LOC), this type of lightning strike can last from around 40 milliseconds to nearly a third of a second.

6. Why Hot lighting has more potential of triggering a wildfire than typical lightning?

  • Lightning with continuing currents can transport more energy from cloud to ground than typical lightning. When lightning with continuing currents attaches to ground or vegetation, they produce more Joule heating and higher temperature than typical lightning, increasing the probability of ignition.
  • With the help of computer simulations, the researchers also looked at the frequency of "hot lightning" strikes and observed that as the atmosphere warms, there might be an increase of 41 percent in the incidents of LCC strikes by 2090.
  • This means that the rate of such lightning flashes could jump from three strikes per second globally to four strikes per second. Meanwhile, the frequency of all cloud-to-ground strikes might increase to nearly eight flashes per second, a 28 percent jump.
  • According to the study, the areas that might witness a significant increase in wildfires triggered by the LCC strikes are Southeast Asia, South America, Africa, Australia, North, America, and Europe.
  • The researchers predicted this after accounting for changes in precipitation, humidity, and temperature.
  • However, many northern polar regions might see a decrease in wildfires as rainfall is projected to increase while "hot lightning " rates remain constant.

7. Government initiatives to tackle this problem

  • Lightning Alert System provides a location-specific forecast of thunder, lightning, strong winds, high winds, and hailstorms occurrences for up to 48 hours.
  • The Common Alert Protocol (CAP) system has been released by the National Disaster Management Authority (NDMA) to alert citizens to imminent thunderstorms and lightning.
  • From the INSAT-3DR satellite, which uploads data every 15 minutes, ISRO provides information about convective clouds.
  • A GPS notification from the Damini App, which was created by the Indian Institute of Tropical Meteorology and Earth System Science organization, alerts users when lightning is nearby and is between 20 to 40 kilometers away.

8. National Oceanic and Atmospheric Administration (NOAA)

The National Oceanic and Atmospheric Administration is an American Scientific and regulatory agency within the United States Department of Commerce that forecasts weather monitors oceanic and atmospheric conditions, chart the seas, conducts deep sea exploration, and manages fishing and protection of marine mammals and endangered species.
NOAA provides services to its customers and information pertaining to the state of the oceans and the atmosphere, such as weather warnings and forecasts via the National Weather Service.

NOAA’s five fundamental activities are

  • Monitoring and observing Earth systems with instruments and data collection networks.
  • Understanding and describing Earth systems through research and analysis of data.
  • Assessing and predicting the changes in these systems over time.
  • Engaging, advising, and informing the public and partner organizations with relevant information.
  • Custodianship of environmental resources.

SUSTAINABLE HARNESSING AND ADVANCEMENT OF NUCLEAR ENERGY FOR TRANSFORMING INDIA (SHANTI) ACT

 
 
1. Context
 
In a significant move to repurpose ageing coal-fired power infrastructure, a government panel has shortlisted at least three old thermal power plant sites for setting up of new nuclear power projects
 
 
2. Why is SHANTI significant?
 
 
  • The SHANTI framework seeks to open India’s nuclear energy sector to private participation and may also facilitate the inflow of foreign investment.
  • At present, the construction and operation of nuclear power plants are restricted exclusively to public sector entities.
  • India aims to scale up its nuclear capacity from the existing 8.8 GW—roughly 1.5% of total installed power capacity—to 100 GW by 2047, thereby raising nuclear energy’s share in electricity generation from around 3%.
  • Public sector nuclear utilities estimate that they will contribute nearly 54 GW of this expansion, with the remaining capacity expected to come from private players
 
3. What are the major differences in SHANTI?
 
 
  • Because of nuclear energy’s association with atomic weapons, the movement and use of nuclear fuel such as uranium are subjected to rigorous oversight to prevent its diversion for the production of weapons-grade plutonium.
  • Past disasters—including the 1979 Three Mile Island accident, the 1986 Chernobyl catastrophe, and the Fukushima core meltdown triggered by the 2011 tsunami—have reinforced a global culture of caution, leading to stringent controls over every stage of nuclear plant functioning.
  • Internationally, there is now broad agreement that in the event of a nuclear accident, the operator of the facility bears the primary responsibility for compensating affected individuals in proportion to the harm caused.
  • Such compensation must be provided promptly, without waiting for investigations into causation or fault.
  • Subsequently, however, the operator may seek reimbursement if it can demonstrate that the accident resulted not from managerial failure but from defective equipment supplied by another party
  • Under the earlier Civil Nuclear Liability framework, operators were permitted to pursue recourse against equipment providers in three situations: first, where an explicit contractual provision existed; second, where the incident was attributable to defects in the supplier’s equipment; and third, where the damage was caused by a deliberate act intended to inflict nuclear harm.
  • The SHANTI legislation removes the second ground for recourse. Even after the 2008 Indo-US civil nuclear agreement, which reopened India’s access to uranium supplies and advanced nuclear technology following restrictions imposed after the 1974 and 1998 nuclear tests, reactor manufacturers from the United States and France remained reluctant to enter the Indian market due to the potential exposure to massive liability claims.
  • By eliminating this clause—and even removing explicit references to “suppliers”—the proposed framework effectively addresses these concerns
 
4. Will SHANTI spur India’s nuclear vision?
 
  • Homi Bhabha, regarded as the architect of India’s nuclear energy programme, envisaged nuclear power as a cornerstone of the country’s energy security while also overcoming India’s limited uranium reserves through the eventual use of thorium.
  • His three-stage plan begins with the construction of pressurised heavy water reactors that utilise natural uranium (U-238) to generate electricity and produce plutonium as a by-product.
  • The second stage involves fast breeder reactors, which are designed to generate additional plutonium and uranium-233 while producing power. In the third and final stage, uranium-233 is combined with India’s abundant thorium resources to generate electricity, creating a largely self-reliant thorium-based nuclear system.
  • India has yet to transition fully into the second stage, having only a prototype fast breeder reactor so far. This project, delayed by nearly two decades, was earlier scheduled to become operational in 2025 but has now been postponed further, with commissioning expected in September 2026.
  • To meet its near-term nuclear energy targets, India is increasingly exploring Small Modular Reactors (SMRs).
  • These are scaled-down versions of conventional reactors currently deployed in countries such as the United States and France, and they require enriched uranium-235—a resource that India does not possess in sufficient quantities. Like India’s first-stage reactors, SMRs generate various radioactive by-products, including plutonium and strontium.
  • SMRs are expected to be manufactured in modular components across multiple locations and assembled at a central site, much like the global production processes used for aircraft or smartphones.
  • However, due to their smaller size, they produce less electricity per unit compared to large reactors. They also do not offer a fundamentally superior solution to nuclear waste management, although some designs incorporate enhanced safety features that allow automatic shutdown during emergencies.
  • While SMRs may contribute to electricity generation, they do little to advance India’s long-term objective of transitioning to thorium-based nuclear power
 
5. Way Forward
 

Under the previous legal framework, victims of a nuclear incident could seek compensation from the plant operator up to a ceiling of ₹1,500 crore. Any damage beyond this limit was to be covered by the Union government through an insurance mechanism, capped at ₹4,000 crore. The SHANTI legislation introduces a tiered liability structure instead. Operators of facilities with a capacity exceeding 3,600 MW would face a maximum liability of ₹3,000 crore. For plants in the 1,500–3,600 MW range, the liability limit is set at ₹1,500 crore; for capacities between 750 MW and 1,500 MW, it is ₹750 crore; for 150–750 MW plants, the cap is ₹300 crore; and facilities below 150 MW carry a liability limit of ₹100 crore. At present, all nuclear power plants in India have capacities of 3,000 MW or less.

Science Minister Jitendra Singh, who introduced the Bill in Parliament, explained that this differentiated structure was designed to avoid deterring private sector investment. However, during parliamentary discussions, concerns were raised that the actual costs of compensation in major nuclear accidents have historically run into several billions of dollars, far exceeding the proposed liability ceilings

CHOLAS

 
 
1.Context
 
More than 300 years after they were taken away from a remote site in Tamil Nadu’s Nagapattinam, the 11th century Chola plates were handed over to India by the Netherlands on Saturday during Prime Minister Narendra Modi’s visit, marking a significant milestone in New Delhi’s pitch for restitution of colonial pillage. 
 

2.Cholas in South India

  • Terms of the scale of accomplishments in art and architecture and the wealth of writing and epigraphic records, the Cholas would come across as one of the richest dynasties in South Indian history
  • There is a profusion of inscriptions that give meticulous details about administration, social life, and material culture… The Brihadeshwara Temple alone which was consecrated in 1010 CE by Rajaraja I has nearly a hundred inscriptions.
  • It is also claimed that the Cholas were one of the longest recorded dynasties in world history
  • At the peak of their rule in the ninth and tenth centuries, the entire area south of the Tungabhadra River was brought together as a single unit under the Cholas.
  • They were perhaps the only dynasty from Southern India to have moved north, marching into Eastern India, where Rajendra Chola is known to have defeated the Pala king of Pataliputra
  • They were also the first empire with grand commercial and territorial ambitions outside of the Indian subcontinent
 

3.About Cholas

  • The earliest references to the Cholas date as far back as the third century BCE and were made by the Mauryan emperor Ashoka
  • However, very little evidence exists about the early Cholas, apart from the early Tamil literature of the third Sangam, and the references made about them in an ancient Graeco-Roman periplus written in the early centuries of the Common Era.
  • The Chola Empire as we know it in all its glory emerged sometime in the mid-ninth century under King Vijayalaya Chola
  • The dynasty of Vijayalaya left behind a vast number of stone inscriptions and some copper plate grants, which have, in the last few decades, been the main source for reconstructing the history of the Cholas.
  • The Chola empire was at its most expansive under Arulmozhivarman, who on acceding to the throne in 985 CE, adopted the regnal title of Rajaraja or king of kings
  • The doyen of South Indian history, Nilakantha Sastri, in his 1955 book The Cholas, writes that under Rajaraja I and his successors, the Chola Empire had reached the capacity of ‘Byzantine royalty’ with its numerous palaces, officials and ceremonials and its majestic display of the concentrated resources of an extensive empire. 
  • According to Sastri, with the emergence of Rajaraja I, the monarchy underwent a substantial transformation, with the king now becoming an emperor. In his official records, Rajaraja I was referred to as the “emperor of the three worlds” or as possessing the whole universe.

4.Cholas vs Pandyas

The Cholas, along with the Pandyas of Madurai and the Cheras were the three great kingdoms of ancient Tamilakam which roughly corresponds to present-day Tamil Nadu, Kerala, Puducherry, Lakshadweep and the southern parts of Andhra Pradesh and Karnataka
By the time Rajaraja I came to the throne, the Cholas had gained the upper hand over the Pandyas and emerged as the primary power in the northern and eastern parts of the Tamil country.

 5.Cholas Expeditions

  • Rajaraja Chola established himself as one of the most astute political and military strategists that southern India had ever seen
  • By the close of the 10th century, he had overrun almost all of the Pandya territories and appointed his own governors there
  • He then moved to Sri Lanka, ransacking some of the greatest of Buddhist viharas and establishing the presence of the Cholas through the building of Shiva temples.
  • The expansion of the Chola empire continued under Rajaraja Chola’s son, Rajendra Chola, also known as Rajendra the Great or Gangaikonda Chola (the Chola who conquered Ganga)
  • He built the Chola capital at Gangaikondacholapuram (close to present-day Tiruchirapalli) to commemorate his victory over the Pala dynasty in present-day Bengal in 1025 CE. 
  •  He then erected a gigantic Shiva temple in it as a mark of thanksgiving to the lord.
  • Rajendra became one of the only Indian monarchs to conquer territory outside the Indian subcontinent
  • In 1025 CE, he sent a naval expedition to Indochina, the Malay Peninsula and Indonesia. His expansion to Southeast Asia was crucial in establishing trade and cultural links with the region
  • The influence of the Cholas can be seen in the language and society of large parts of Southeast Asia as well
  • The deification of kings in Cambodia and Thailand as incarnations of Brahmanical Gods, for instance, is a most evident imprint of the Cholas.
  • The medieval Chola empire began to decline in 1070 CE, after the death of Virarajendra Chola, the son of Rajendra Chola.
  • A period of chaos prevailed, which ended with the emergence of the Later Cholas, a dynasty that was the product of alliances between the Cholas and the Eastern Chalukyas.

6. Gangaikonda cholapuram

 
  • Before Rajendra I, the Chola throne was held by his father, the renowned Rajaraja I, who was responsible for constructing the iconic Brihadeeswara Temple in Tanjore (modern-day Thanjavur).
  • The term ‘Brihadeeswara’ translates to ‘great’ or ‘massive’—with ‘brihad’ in Sanskrit signifying largeness. Interestingly, this term is also associated with the temple established by Rajendra I, as listed in UNESCO’s World Heritage records.
  • The Gangaikonda Cholapuram Temple, dedicated to Lord Shiva and recognized as a UNESCO World Heritage Site, is often regarded as the zenith of Chola architectural achievement.
  • It stands as a monumental symbol of the Chola Empire’s grandeur, reflecting an era when its influence extended from the banks of the Ganga in northern India to regions of Southeast Asia, including Sumatra, Malaysia, and Myanmar.
  • Built around 1030 CE, roughly 20 years after the Brihadeeswara Temple, Rajendra’s temple followed a similar architectural style but displayed greater intricacy and finesse.
  • This stylistic richness mirrors the Chola Empire’s prosperity during his reign. While the Tanjore temple features a tall, upright tower projecting power and dominance, the Gangaikonda Cholapuram temple is distinguished by its graceful curves and refined form—signaling a more confident and aesthetically sophisticated expression of imperial strength.
  • Even today, the temple remains a vibrant cultural center, especially during the Aadi Thiruvadhirai festival. ‘Aadi’ refers to the Tamil month, and ‘Thiruvadhirai’ is a star (nakshatra) traditionally associated with Lord Shiva and believed to be Rajendra I’s birth star. As part of the festivities, therukoothu (street theatre) performances reenact the king’s accomplishments, and his statue is ceremonially adorned with new silk garments

7.Art & Culture

  • From the 10th century onward, the Cholas more prominently started making structural temples
  • The gigantic Brihadeshwara Temple in Thanjavur is perhaps one of the finest examples of the Cholas’ artistic brilliance
  • Inscriptional evidence in Chola art also points to the prominent role played by royal women and dancers in the patronage of art and architecture
  • One of the most celebrated patrons was the widowed queen of Gandaraditya Chola, Sembiyan Mahadevi.
  • An avid temple builder, she is well known for her contributions to temples such as Umamaheshvar Temple at Konerirajapuram, Tirukkurangaduturai Temple at Aduturai, Tirukkotisvarar Temple at Tirukkodikkaval among other
  • Under the Chalukyas you had the basic design of the structural temples coming in and under the Pallavas, the rock-cut temple art emerged. But it is the scale of temple building activities under the Cholas that mark them out
  • The pyramidal vimana of the Brihadeshwara temple of 66 metres is one of the tallest buildings in antiquity
  • The Gangaikonda Cholapuram temple with its catenary-shaped vimana is also a unique engineering marvel

INDUS WATER TREATY

1. Context

 India on Saturday rejected the “so-called award” issued on May 15 by the “illegally constituted so-called” Court of Arbitration (CoA) regarding disputes with Pakistan over the Indus Waters Treaty (IWT). 
 

2. Is unilateral suspension permissible?

 

  • The Indus Waters Treaty (IWT) cannot be modified or terminated by one country alone. Article XII explicitly states that the agreement may only be ended through a "duly ratified treaty" mutually accepted by both India and Pakistan.

  • India’s reference to placing the treaty “in abeyance” in its communication with Pakistan lacks legal grounding, as international law and the Vienna Convention on the Law of Treaties (VCLT), 1969—which serves as the foundational framework for international agreements—do not recognize this term.

  • Under Article 62 of the VCLT, a treaty may be withdrawn from if there has been a “fundamental change of circumstances” compared to when it was first signed.

  • Although India is not a signatory and Pakistan has signed but not ratified the VCLT, the International Court of Justice (ICJ), in its ruling on the Fisheries Jurisdiction cases, recognized Article 62 as part of customary international law—making it applicable even without formal ratification.

  • India appears to be appealing to this legal doctrine in its letter, which emphasized that a “fundamental change in circumstances” warrants a reassessment of its commitments under the IWT.

  •  For instance, in the 1997 Gabcíkovo-Nagymaros case involving Hungary and Slovakia’s dam project, Hungary claimed that evolving political and economic conditions, along with potential environmental risks, justified ending the treaty.

  • The ICJ dismissed these claims, asserting that the cited changes were not directly tied to the treaty’s central goal of cooperative energy generation

3.How will this have effect on Pakistan?

  • Over 80% of Pakistan’s agricultural activities and nearly one-third of its hydropower production rely on the Indus basin's water resources.
  • Despite this heavy dependence, analysts point out that India does not have the extensive water storage facilities or a widespread canal network necessary to retain the vast volumes—tens of billions of cubic metres—of water from the western rivers.
  • India’s existing infrastructure primarily comprises run-of-the-river hydropower projects, which are not designed for significant water storage.
  • Nevertheless, the primary concern lies in the unpredictability of water flows, which poses a serious threat to Pakistan’s largely agriculture-based economy

4. Applications moved by Pakistan and India earlier

  • The World Bank, the third party to the Treaty and the acknowledged arbiter of disputes were, meanwhile faced with a unique situation of having received two separate requests for the same dispute.
  • New Delhi feels that the World Bank is just a facilitator and has a limited role.
  • On December 12, 2016, the World Bank announced a "pause" in the separate processes initiated by India and Pakistan under the Indus Waters Treaty to allow the two countries to consider alternative ways to resolve their disagreements.
  • The regular meetings of Indus Waters Commissioners resumed in 2017 and India tried to use these to find mutually agreeable solutions between 2017 and 2022.
  • Pakistan refused to discuss these issues at these meetings.
  • At Pakistan's continued insistence, the World Bank, in March last year, initiated actions on the requests of both India and Pakistan.
On March 31, 2022, the World Bank decided to resume the process of appointing a Neutral Expert and a Chairman for the Court of Arbitration.
In October last year, the Bank named Michel Lino as the Neutral Expert and Prof. Sean Murphy as Chairman of the Court of Arbitration.
  • They will carry out their duties in their capacity as subject matter experts and independently of any other appointments they may currently hold.
  • On October 19, 2022, the Ministry of External Affairs said, " We have noted the World Bank's announcement to concurrently appoint a Neutral Expert and a Chair of the Court of Arbitration in the ongoing matter related to the Kishanganga and Ratle projects".
  • Recognising the World Bank's admission in its announcement that "carrying out two processes concurrently poses practical and legal challenges".
  • India would assess the matter that "India believes that the implementation of the Indus Water Treaty must be in the letter and spirit of the Treaty".
  • Such parallel consideration of the same issues is not provided for in any provisions of the Treaty and India has been repeatedly citing the possibility of the two processes delivering contradictory rulings, which could lead to an unprecedented and legally untenable situation, which is unforeseen in Treaty provisions.

5. Dispute redressal mechanism 

  • The dispute redressal mechanism provided under Article IX of the IWT is graded.
  • It's a 3-level mechanism.
  • So, whenever India plans to start a project, under the Indus Water Treaty, it has to inform Pakistan that it is planning to build a project.
  • Pakistan might oppose it and ask for more details. That would mean there is a question and in case there is a question, that question has to be clarified between the two sides at the level of the Indus Commissioners.
  • If that difference is not resolved by them, then the level is raised. The question then becomes a difference.
  • That difference is to be resolved by another set mechanism, which is the Natural Expert.
  • It is at this stage that the World Bank comes into the picture.
  • In case the Neutral Expert says that they are not able to resolve the difference or that the issue needs an interpretation of the Treaty, then that difference becomes a dispute.
    It then goes to the third stage the Court of Arbitration.
  • To Sum up, it's a very graded and sequential mechanism first Commissioner, then the Neutral Expert and only then the Court of Arbitration.

6. India's notice and its implications

  • While the immediate provocation for the modification is to address the issue of two parallel mechanisms, at this point, the implications of India's notice for modifying the treaty are not very clear.
  • Article XII (3) of the Treaty that India has invoked is not a dispute redressal mechanism.
  • It is in effect, a provision to amend the Treaty.
  • However, an amendment or modification can happen only through a "duly ratified Treaty concluded for that purpose between the two governments". 
  • Pakistan is under no obligation to agree to India's proposal.
  • As of now, it is not clear what happens if Pakistan does not respond to India's notice within 90 days.
The next provision in the Treaty, Article XII (4), provides for the termination of the Treaty through a similar process " a duly ratified Treaty concluded for that the purpose between the two governments".
  • India has not spelt out exactly what it wants to be modified in the Treaty.
  • But over the last few years, especially since the Uri attack, there has been a growing demand in India to use the Indus Waters Treaty as a strategic tool, considering that India has the natural advantage of being the upper riparian state.
  • India has not fully utilized its rights over the waters of the three east-flowing rivers Ravi, Beas and Sutlej over which India has full control under the Treaty.
    It has also not adequately utilized the limited rights over the three west-flowing rivers Indus, Chenab and Jhelum which are meant for Pakistan.
  • Following the Uri attack, India established a high-level task force to exploit the full potential of the Indus Waters Treaty.
  • Accordingly, India has been working to start several big and small hydroelectric projects that had either been stalled or were in the planning stages.
7. Indus river System
 
  • A river system consists of a river and all its tributaries. The Indus River system is made up of six rivers: Indus, Jhelum, Chenab, Ravi, Beas, and Sutlej. Among these, the Indus and Sutlej are antecedent rivers, meaning they existed before the formation of the Himalayas and carved deep gorges as they flowed from the Tibet region. The remaining four rivers—Jhelum, Chenab, Ravi, and Beas—originate in India.
  • The Indus Basin stretches across four countries: China, India, Pakistan, and Afghanistan. In India, it covers the Union Territories of Ladakh and Jammu and Kashmir, as well as Chandigarh, and the states of Himachal Pradesh, Punjab, Haryana, and Rajasthan. The total drainage area of the basin is about 3,21,289 square kilometers, representing roughly 9.8% of India’s total geographical area.
Western rivers
  • The Indus River originates from the trans-Himalayan range near Mansarovar Lake in Tibet, known as Singi Khamban or the Lion’s Mouth. Flowing west, it enters India at Demchok in Ladakh.
  • Within India, the river runs for about 1,114 kilometers, flowing between the Ladakh and Karakoram ranges. Its main right bank tributaries include the Shyok (originating from Rimo Glacier), Shigar, and Gilgit, while the Zaskar and Hanle rivers are its left bank tributaries. The Indus River travels a total of 2,880 kilometers, eventually emptying into the Arabian Sea near Karachi, Pakistan. The Indus River Dolphin, listed as endangered by the International Union for Conservation of Nature (IUCN), primarily inhabits the Indus.
  • The Jhelum River (252 km) begins at Verinag near the Pir Panjal in India, flowing through Wular Lake in Srinagar before entering Pakistan, where it merges with the Chenab near Jhang. The Chenab River, the Indus’s largest tributary, is 1,180 km long within India and originates from the confluence of the Chandra and Bhaga rivers at Tandi in Keylong, Himachal Pradesh.
Eastern river
  • The Ravi River (95 km) starts from the Kullu Hills near Rohtang Pass in Himachal Pradesh and joins the Chenab at Sarai Sidhu in Pakistan. The Beas River (354 km) originates from Beas Kund, located at 4,000 meters above sea level near Rohtang Pass. It flows through the Kullu Valley and joins the Sutlej near Harike in Punjab, India. The Harike Barrage, built in 1952, diverts water for the Indira Gandhi Canal system.
  • The Sutlej River (676 km) is another antecedent river, originating from Rakas Tal (4,555 meters above sea level) near Mansarovar in Tibet. It enters India near Ropar. India has built several important dams to harness the waters of the eastern rivers, including the Ranjit Sagar Dam on the Ravi, the Bhakra Dam on the Sutlej, and the Pong and Pandoh Dams on the Beas. These projects, including the Beas-Sutlej Link, the Madhopur-Beas Link, and the Indira Gandhi Canal Project, allow India to utilize nearly 95% of the waters of these eastern rivers.

 

8. Way Forward

However, India’s projects on the western rivers have been a source of dispute with Pakistan. Significant projects on the western rivers, such as the Salal Dam, the Baglihar Hydropower Project, the Pakal Dul Project, and the Kiru Project, are located on the Chenab River, while the Tulbul Project is situated on the Jhelum River in Jammu and Kashmir. These projects have been at the center of objections from Pakistan over the year
