GRADED RESPONSE ACTION PLAN(GRAP)

 

1.Context

 In a move to combat air pollution during the winter months, the Delhi government has notified a series of restrictions that will come into force from November 1 to February 28 every year — from curbs on vehicles and construction activities, to staggered office timings and work from home.

2.What is a Graded Response Action Plan (GRAP)

In 2014, when a study by the WHO found that Delhi was the most polluted city in the world, panic spread in the center and the state government. Approved by the supreme court in 2016, the plan was formulated after several meetings that the Environmental Pollution (Prevention and Control) Authority (EPCA) held with state government representatives and experts. The result was a plan that institutionalized measures to be taken when air quality deteriorates.
The plan was notified by the Ministry of Environment, Forests & Climate change in 2017.
GRAP works only as an emergency measure.
 
It institutionalized measures to be taken when air quality deteriorates.
1. The plan is incremental- therefore, when the air quality moves from 'poor' to 'very poor, the measures listed under both sections have to be followed.
2. It prevents PM10 and PM2.5 levels from going beyond the 'moderate' national AQI category.
 
Authorities from both Haryana and UP had informed EPCA at the time that they would put in the required measures by winter 2020 for the supply of electricity from the grid.

3.Has GRAP Helped?

  • The biggest success of GRAP has been in fixing accountability and deadlines.
  • For each action to be taken under a particular air quality category, executing agencies are marked.
  • In a territory like Delhi, where a multiplicity of authorities has been a long-standing impediment to effective governance, this step made a crucial difference.

4.Measures that are taken in other states

  • one criticism of the EPCA, as well as GRAP, has been the focus on Delhi. While other states have managed to delay several measures, citing a lack of resources, Delhi has always been the first to have stringent measures enforced.
  • When the air quality shifts from poor to very poor, the measures listed under both sections have to be followed since the plan is incremental in naturality reaches the severe+ stage, GRAP talks about shutting down schools and implementing the odd-even road-space rationing scheme. 

5.Actions under GRAP

Severe+ or Emergency
(PM 2.5 OVER 300 300 µg/cubic metre or PM10 over 500µg/cu. m. for 48+ hours)
  • Stop construction work.
  • Stop entry of trucks into Delhi.
  • Introduce odd/even schemes for private vehicles and minimize exemptions.
  • Taskforce to decide any additional steps including shutting schools to stop.

Severe
(PM 2.5 OVER 250µg/cu. m. or PM10 over 430 µg/cu. m. )
  • Maximize power generation from natural gas to reduce generation from coal.
  • Close brick kilns, hot mix plants, and stone crushers.
  • More frequent mechanized cleaning of roads and sprinkling of water.

Very Poor
(PM2.5 121-250 µg/cu. m. or PM10 351-430 µg/cu.m. )
  • Increase bus and metro services.
  • Stop the use of diesel generator sets.
  • Enhance parking fee by 3-4 times.
  • Apartment owners discourage burning fires in winter by providing electric heaters during winter.
  • Advisories to people with respiratory and cardiac conditions to restrict outdoor movement.

Moderate to Poor
(PM2.5 61-120 µg/cu. m. or PM10 101-350 µg/cu. m.)
  • Close/enforce pollution control regulations in brick kilns and industries.
  • Heavy fines for garbage burning.
  • Mechanized sweeping on roads with heavy traffic and water sprinkling.
 
6. The Air Quality Index (AQI)
  • The AQI is a colour-coded index launched under the Swachh Bharat campaign to simplify the understanding of pollution levels.
  • It helps convey the condition of the air and guides appropriate measures based on the severity of pollution.
  • The AQI consists of six categories, each with a corresponding colour code: 'Good' (0-50), 'Satisfactory' (51-100), 'Moderately Polluted' (101-200), 'Poor' (201-300), 'Very Poor' (301-400) and 'Severe' (401-500).

 

7. Commission for Air Quality Management (CAQM)

 

  • The Commission for Air Quality Management (CAQM) was established by the Government of India in October 2020 to address the persistent and severe problem of air pollution in the National Capital Region (NCR) and adjoining states.
  • It was later given statutory backing through the Commission for Air Quality Management in National Capital Region and Adjoining Areas Act, 2021. The Commission functions under the Ministry of Environment, Forest and Climate Change (MoEFCC).
  • The CAQM was created in response to the recurring air pollution crisis in Delhi and surrounding areas, which often see hazardous air quality levels, especially during the winter months.
  • The problem is aggravated by factors such as stubble burning in Punjab and Haryana, industrial and vehicular emissions, and construction dust. Earlier, multiple agencies such as the Central Pollution Control Board (CPCB), state pollution control boards, and environment departments operated independently, leading to poor coordination and weak enforcement. The CAQM was envisioned as a centralized, permanent body to unify and coordinate efforts across states.
  • The Commission’s jurisdiction extends to Delhi, Punjab, Haryana, Rajasthan, and Uttar Pradesh, covering areas adjoining the NCR. It is headed by a Chairperson appointed by the Central Government—typically a former Secretary to the Government of India or a Chief Secretary of a state.
  • The body includes representatives from central ministries, state governments, the CPCB, ISRO, and NITI Aayog, along with experts in environmental science and pollution control.
  • The CAQM is responsible for monitoring, coordinating, and implementing air quality management plans across its jurisdiction. It formulates policies to prevent and control air pollution, enforces existing environmental laws, and ensures that central, state, and local authorities act in a coordinated manner.
  • The Commission also plays a critical role in tackling stubble burning, a major seasonal contributor to pollution in northern India. It has the authority to issue directions to central, state, and local authorities, and its orders override those of other agencies within its jurisdiction. Moreover, the Commission possesses powers of a civil court, enabling it to summon individuals, demand documents, and take punitive actions against violators.
  • The establishment of CAQM marks an important step in India’s environmental governance. By creating a single authority with comprehensive powers, the government sought to move away from fragmented approaches and ensure consistent, region-wide enforcement.
  • However, despite its potential, the Commission faces challenges such as jurisdictional overlaps, limited manpower, and the lack of strong enforcement mechanisms at the local level. Successful functioning of CAQM ultimately depends on the cooperation of states, technological monitoring, and public awareness

SANTHAL REBELLION

 
 
 
1. Context
 
A well-known Santal origin narrative, in the form of a song, names Hihiri-Pipiri and Sasan Beda as places in the community’s remembered beginning, even though they cannot be located or identified geographically. They have remained part of the Santal origin story even as the community moved elsewhere..
 
2. Santhal rebellion
 

  • The Santhal uprising, known as ‘Hul’ (meaning revolution), began in 1855—two years prior to the 1857 revolt, which is often described as India’s first major struggle for independence.

  • It represented a coordinated resistance against British colonial rule, where the Santhal community rose in defiance of widespread exploitation—both economic and social—inflicted by British authorities, allied landlords (zamindars), and corrupt moneylenders.

  • This resistance movement, spearheaded by brothers Sidhu and Kanhu, gained support from as many as 32 different castes and communities.

  • The roots of this revolt trace back to 1832, when the British East India Company established the Damin-i-Koh area within the Rajmahal Hills’ forested terrain. The region was designated for Santhals who had been relocated from parts of the Bengal Presidency, including Birbhum, Murshidabad, Bhagalpur, Barabhum, Manbhum, Palamau, and Chhotanagpur.

  • Although the Santhals were promised land and farming opportunities in Damin-i-Koh, they were soon subjected to exploitative practices, including land dispossession and forced labour systems such as kamioti and harwahi. Over time, these abuses intensified under colonial supervision.

  • The rebellion, which erupted in 1855, persisted with violent confrontations until 1856, when the British eventually suppressed it. Using advanced weaponry and war elephants, they crushed the uprising, during which both Sidhu and Kanhu lost their lives

 
 
3. About Santhals
 

  • The Santhals were not indigenous to what is now known as the Santhal Pargana region, which comprises six districts—Dumka, Pakur, Godda, Sahibganj, Deoghar, and parts of Jamtara. Their migration began in the late 1700s from the Birbhum and Manbhum areas, located in present-day West Bengal.

  • The devastating Bengal famine of 1770 prompted the Santhals to relocate. Around this time, the British sought their assistance. Following the introduction of the Permanent Settlement Act in 1790, the East India Company aimed to extend its agricultural control and revenue base.

  • The Damin-i-Koh region, then densely forested, was designated for Santhal settlement to ensure a consistent tax income. However, after resettlement, the Santhals found themselves subjected to severe colonial exploitation.

  • In present times, the Santhals constitute the third-largest tribal group in India, primarily residing in the states of Jharkhand, Bihar, Odisha, and West Bengal.

 
4. Other Tribal rebellions
 

Munda Rebellion:

  • In 1899, Birsa Munda initiated the Ulgulan or Munda rebellion, employing guerrilla tactics and traditional weapons to resist British rule. He urged tribal communities to embrace the concept of Birsa Raj, advocating for the rejection of colonial laws and the refusal to pay rents.
  • This uprising was one of the most strategically coordinated tribal movements, aiming to dismantle British governance, eliminate external influences, and establish a self-governed Munda territory. However, the British, with superior military power, quickly suppressed the revolt. Birsa Munda was captured on March 3, 1900, while resting with his followers in the Jamkopai forest near Chakradharpur.
  • The rebellion had a lasting impact, contributing to the abolition of the begar (forced labour) system and influencing the creation of the Tenancy Act in 1903, which acknowledged the khuntkatti landholding rights. Later, the Chotanagpur Tenancy Act of 1908 restricted the transfer of tribal land to outsiders.

Paika Rebellion:


  • The Paika Rebellion of 1817, centered in Khurda (Odisha), is often regarded as a significant early resistance against British rule—sometimes even called the "first war of Indian independence."
  • The Paikas, traditional soldiers under Odisha's kings, revolted after being stripped of their rent-free land grants. The deposition and exile of the Khurda king in 1803 and the imposition of new revenue policies deeply affected the Paikas, who lost both property and societal privileges.
  • The rebellion escalated when around 400 Kondhs from Ghumusar rose against the British, prompting Bakshi Jagabandhu, the highest-ranking general of the exiled Khurda ruler, to lead the Paikas into battle. Although they engaged in intense combat across various locations, British forces gradually quelled the rebellion

Kol Revolt:

  • In 1831, the Kols of Chhota Nagpur rebelled due to increasing encroachment on their lands by non-tribal settlers, a process enabled by new colonial land policies. Economic exploitation and dispossession led to widespread anger among the indigenous people.
  • Leaders like Buddhu Bhagat, Joa Bhagat, and Madara Mahato spearheaded the revolt, which saw the participation of other tribes such as the Hos, Mundas, and Oraons.
  • Armed mainly with traditional weapons, tribal fighters launched fierce attacks against British forces and local moneylenders. The uprising spanned regions like Ranchi, Hazaribagh, Palamau, and Manbhum, and lasted nearly two years before being crushed by the colonial administration
Bhil Uprising:
  • The Bhils of the Khandesh region in Maharashtra rose against British intrusion in 1818, fearing exploitation under foreign rule. Sewaram led this resistance, but the movement was violently suppressed. A renewed revolt occurred in 1825, as the Bhils sought to exploit British military weaknesses during the First Anglo-Burmese War.
Dhal Revolt:
  • The Dhal Revolt, considered the earliest tribal uprising in Jharkhand, broke out in 1767 under the leadership of Jagannath Dhal, the former ruler of Dhalbhum (now in West Bengal).
  • The rebellion was sparked by resentment against the East India Company's growing influence, which displaced local power structures. The conflict endured for a decade, ending when the British reinstated Jagannath Dhal as the regional king in 1777 to pacify the unrest
 
Tana Bhagat Movement:
  • Launched in 1914 by Jatra Bhagat, a prominent leader of the Oraon tribe, the Tana Bhagat movement aimed to restore indigenous values while rejecting British authority and Western cultural impositions. Focused on agrarian concerns, the movement called for refusal to pay taxes and urged laborers to resist forced or unfair work conditions
 
 
5. Birsa Munda and Janjatiya Gaurav Divas
 
  • Birsa Munda holds a revered place in India’s freedom struggle as one of the most iconic tribal leaders who rose against British colonial rule and social injustice. Born on 15th November 1875 in the village of Ulihatu in present-day Jharkhand, Birsa belonged to the Munda tribe, an indigenous community of the Chotanagpur Plateau.
  • He emerged as a powerful symbol of tribal resistance and social reform at a very young age and came to be known with deep respect as “Dharti Aba”, meaning “Father of the Earth”, for his deep connection with the land and the lives of his people.
  • During the late 19th century, the British administration introduced exploitative land revenue systems and enabled the encroachment of tribal lands by non-tribal landlords and moneylenders.
  • Alongside economic oppression, Christian missionaries sought to convert tribal populations, often undermining traditional tribal customs and beliefs. In this context of rising disenfranchisement, Birsa Munda led a major tribal uprising known as the “Ulgulan”, or the Great Tumult, which took place between 1899 and 1900.
  • This movement, often referred to as the Munda Rebellion, was aimed at expelling the British from the region, ending the zamindari system, and restoring tribal land rights and autonomy.
  • The Ulgulan was not merely a political revolt; it was also a social and spiritual movement. Birsa called upon his people to reject colonial laws, stop paying taxes, and embrace a purer way of life based on indigenous customs and his own vision of a just and egalitarian society, which he termed the “Birsa Raj”.
  • He also preached against superstitions and promoted a moral code among his followers. His ideas quickly gained popularity, and thousands rallied behind him, making the movement one of the most organized tribal uprisings during colonial rule.
  • However, the rebellion was short-lived. In March 1900, Birsa Munda was captured while asleep in the Jamkopai forest. He died under mysterious circumstances in Ranchi Jail on 9th June 1900, at the age of just 25.
  • Despite his early death, his legacy endured, and he became a lasting symbol of tribal pride, resistance, and identity.
  • In recognition of his immense contribution to India’s freedom struggle and the assertion of tribal rights, the Government of India declared 15th November, Birsa Munda’s birth anniversary, as “Janjatiya Gaurav Divas”.
  • The day is observed across the country to celebrate and honour the valour, sacrifices, and contributions of tribal freedom fighters, not just Birsa Munda, but many others who stood up against colonial and feudal exploitation.
  • It serves as a reminder of the unique and crucial role that tribal communities have played in shaping India’s history and preserving its cultural diversity

FUNDAMENTAL RIGHTS

 
 
 
1. Context
 
Supreme Court recognised walking on demarcated footpaths as a fundamental right and urged the government to introduce a law that declares this right. The two-judge bench’s ruling came in a case involving the death of a schoolboy in a road accident.
 
 
2. What are the Fundamental Rights?
 
 
  • Fundamental Rights are the basic human rights guaranteed by the Constitution of India to all citizens (and, in some cases, to all persons). They are contained in Part III (Articles 12–35) of the Constitution.
  • These rights protect the dignity, liberty, equality, and freedom of individuals against arbitrary actions of the State. They also ensure the establishment of a democratic and welfare-oriented society.
  • Fundamental Rights form the cornerstone of the Indian Constitution by balancing individual liberty with societal interests. They guarantee equality, freedom, justice, and human dignity while ensuring that governmental power remains subject to constitutional limitations.
  • Through judicial interpretation, particularly under Article 21, these rights have evolved into dynamic instruments for protecting civil liberties and promoting constitutional morality, making them indispensable to India's democratic framework
 
3. What are the constitutional articles related to it?
 
 
  • Right to Equality (Articles 14–18)
    • Equality before the law
    • Prohibition of discrimination
    • Equality of opportunity in public employment
    • Abolition of untouchability
    • Abolition of titles
  • Right to Freedom (Articles 19–22)
    • Freedom of speech and expression
    • Freedom of assembly
    • Freedom to form associations
    • Freedom of movement
    • Freedom to reside anywhere in India
    • Freedom to practice any profession
    • Protection in respect of conviction for offences
    • Protection of life and personal liberty
    • Protection against arbitrary arrest and detention
  • Right against Exploitation (Articles 23–24)
    • Prohibition of human trafficking and forced labour
    • Prohibition of child labour in hazardous occupations
  • Right to Freedom of Religion (Articles 25–28)
    • Freedom of conscience and religion
    • Freedom to manage religious affairs
    • Freedom from certain religious taxes
    • Freedom from religious instruction in certain educational institutions
  • Cultural and Educational Rights (Articles 29–30)
    • Protection of the interests of minorities
    • Right of minorities to establish and administer educational institutions
  • Right to Constitutional Remedies (Article 32)
    • Right to approach the courts for enforcement of Fundamental Rights. B. R. Ambedkar called this the "heart and soul" of the Constitution.
 
 
4. Fundamental Rights Available Only to Citizens
 
 
 
 
  • The Constitution of India guarantees several Fundamental Rights under Part III (Articles 12–35). While many of these rights are available to all persons, including foreigners, certain rights are reserved exclusively for Indian citizens.
  • These rights recognize the special legal and political relationship between the State and its citizens.
  • They primarily relate to equality, freedom, participation in public affairs, and the protection of India's cultural and educational heritage.
  • The Fundamental Rights available only to citizens are contained in Articles 15, 16, 19, 29, and 30.
 
  • Article 15 prohibits the State from discriminating against any citizen solely on the grounds of religion, race, caste, sex, or place of birth. The objective of this provision is to ensure equality in public life and prevent unfair treatment based on social or personal characteristics
  • Article 16 guarantees equal opportunity to all citizens in matters relating to employment or appointment under the State. Every citizen has the right to compete for public employment without arbitrary discrimination
  • Article 19 is one of the most significant Fundamental Rights because it guarantees the essential freedoms required for the functioning of a democratic society. These freedoms are available only to Indian citizens.
  • Article 29(1) provides that any section of the citizens residing in India having a distinct language, script, or culture has the right to conserve and preserve it. This provision recognizes India's immense cultural and linguistic diversity and seeks to protect the identity of different communities.
  • Article 29 ensures that communities can preserve their traditions, language, literature, and cultural heritage without interference.
  • Article 29(2) further prohibits denial of admission into educational institutions maintained by the State or receiving State aid solely on grounds of religion, race, caste, language, or any of them.
  • Article 30 grants religious and linguistic minorities the right to establish and administer educational institutions of their choice. The objective is to preserve the identity, culture, language, and traditions of minority communities through education.
 
 
5. Fundamental Rights and Duties Difference
 
 
  • The Fundamental Rights and Fundamental Duties are two essential features of the Constitution of India.
  • While Fundamental Rights guarantee certain freedoms and protections to individuals against arbitrary State action, Fundamental Duties remind citizens of their moral and civic obligations towards the nation. Together, they seek to establish a balance between individual liberty and social responsibility, thereby strengthening Indian democracy.
  • Fundamental Rights are contained in Part III (Articles 12–35) of the Constitution, whereas Fundamental Duties are contained in Part IVA (Article 51A).
  • The Fundamental Duties were inserted by the Forty-second Amendment of the Constitution of India on the recommendation of the Swaran Singh Committee.
  • Later, the Eighty-sixth Amendment of the Constitution of India added the eleventh Fundamental Duty, requiring parents or guardians to provide educational opportunities to children between the ages of six and fourteen years.

 

Fundamental Rights and Fundamental Duties are complementary rather than contradictory. Rights enable citizens to enjoy freedom and dignity, while duties ensure that these freedoms are exercised responsibly without harming society or the nation.

For example:

  • The Right to Freedom of Speech and Expression should be exercised responsibly without promoting hatred or violence.
  • The Right to Freedom of Religion should be balanced with the duty to promote harmony and the spirit of common brotherhood.
  • The Right to Education is complemented by the duty of parents or guardians to provide educational opportunities to children between six and fourteen years of age.
  • The Right to a Clean Environment, recognized through judicial interpretation of Article 21, is supported by the duty to protect and improve the natural environment under Article 51A(g).

 

6. Way Forward
 
The Supreme Court on 19th June held that the right to walk on secured footpaths is a fundamental right and urged the government to bring a law that declares this right and recognises the duty of municipal authorities and local bodies to build, demarcate, and maintain necessary pedestrian infrastructure

MADDEN-JULIAN OSCILLATION

 
 
 
 
1. Context
 
After remaining largely inactive for more than a week, the monsoon finally picked some strength and momentum beginning Monday. Maharashtra, for instance, received its first good rainfall of the season on Tuesday.
 
 
2. What is the Madden-Julian oscillation?
 
  • The Madden–Julian Oscillation (MJO) is one of the most important atmospheric phenomena in the tropical region of the Earth. It is a large-scale pattern of atmospheric circulation characterized by alternating periods of enhanced and suppressed rainfall that travels eastward around the equator.
  • Unlike cyclones, which are localized weather systems, or seasonal climate phenomena such as the El Niño–Southern Oscillation (ENSO), the MJO is an atmospheric disturbance that continuously moves across the tropical oceans, influencing weather conditions over vast geographical areas.
  • The phenomenon was first identified in 1971 by meteorologists Roland Madden and Paul Julian, after whom it is named. Their research showed that tropical rainfall and atmospheric pressure exhibit a recurring pattern that moves eastward around the globe over a period of about one to two months.
  • The MJO originates most frequently over the tropical Indian Ocean, where warm ocean waters provide the energy necessary for the development of deep convection.
  • The system then moves eastward across the maritime continent, including Indonesia, into the tropical Pacific Ocean and, on some occasions, continues into the Atlantic Ocean before gradually weakening. The entire cycle generally takes between 30 and 60 days, although it may sometimes extend to nearly 90 days.
  • The MJO consists of two distinct phases: the active (enhanced) phase and the suppressed phase. During the active phase, warm, moist air rises from the Earth's surface, leading to the formation of extensive cloud cover, heavy rainfall, and intense thunderstorm activity.
  • This upward movement of air releases large amounts of latent heat, strengthening atmospheric circulation. In contrast, the suppressed phase is characterized by sinking air, which inhibits cloud formation and results in clear skies, reduced rainfall, and relatively dry weather conditions.
  • As the MJO moves eastward, these two phases travel together, causing alternating wet and dry periods in tropical regions.
  • One of the reasons the MJO is scientifically important is that it serves as a bridge between short-term weather events and long-term climate variability.
  • While ordinary weather systems usually last for only a few days, and climate phenomena like ENSO persist for several months or even years, the MJO operates on an intra-seasonal timescale, making it highly valuable for forecasting weather several weeks in advance.
  • The MJO has a profound influence on the Indian monsoon. When its active phase is located over the tropical Indian Ocean and surrounding regions, convection increases significantly, leading to enhanced monsoon rainfall over India.
  • This often results in active monsoon spells with widespread precipitation. Conversely, when the suppressed phase dominates the region, rainfall decreases, leading to weak or break monsoon conditions.
  • Therefore, meteorologists closely monitor the MJO to improve monsoon forecasts and assess the likelihood of heavy rainfall or prolonged dry spells.
  • The influence of the MJO is not limited to the Indian monsoon. It also plays a major role in the formation and intensification of tropical cyclones over the Indian Ocean, the Pacific Ocean, and even parts of the Atlantic Ocean.
  • During its active phase, the atmosphere becomes more unstable, humidity increases, and vertical wind conditions become more favourable for cyclone development. As a result, periods of increased cyclone activity often coincide with the passage of the active MJO phase.
  • Apart from affecting tropical weather, the MJO also influences atmospheric circulation in higher latitudes through a process known as teleconnection.
  • Changes in tropical convection caused by the MJO can alter jet stream patterns, influencing winter storms, cold waves, heat waves, and heavy rainfall events in regions far away from the tropics, including North America, Europe, and East Asia. Thus, despite being a tropical phenomenon, its impacts extend across the globe.
  • The MJO is often confused with the El Niño–Southern Oscillation, but the two are fundamentally different.
  • The MJO is a moving atmospheric disturbance that travels continuously around the globe and lasts only a few weeks to a couple of months. ENSO, on the other hand, is a coupled ocean-atmosphere phenomenon centred over the equatorial Pacific Ocean and typically persists for several months to two years or more.
  • While ENSO changes sea surface temperatures significantly, the MJO primarily affects atmospheric circulation and rainfall without producing major long-term changes in ocean temperatures.
  • An easy way to understand the MJO is to imagine the tropical atmosphere as a giant circular race track. The active phase of the MJO resembles a moving cluster of rain-bearing clouds that travels steadily around this track, bringing heavy rainfall and thunderstorms wherever it passes.
  • Behind this active phase follows the suppressed phase, which brings relatively dry and clear weather. This continuous movement creates alternating periods of wet and dry conditions across tropical regions
 
 
3. How does the Madden-Julian oscillation affect India?
 
 
  • The Madden–Julian Oscillation (MJO) has a significant influence on India's weather, particularly the Southwest Monsoon, tropical cyclones, and extreme rainfall events.
  • Since the MJO is a moving region of enhanced and suppressed convection (thunderstorm activity), its position relative to India determines whether the country experiences increased rainfall or dry conditions.
  • The MJO usually originates over the tropical Indian Ocean and moves eastward across the maritime continent and the Pacific Ocean. When the active phase of the MJO is located over the Indian Ocean and the region surrounding India, it strengthens the upward movement of warm, moist air.
  • This leads to increased cloud formation, widespread thunderstorms, and heavy rainfall over many parts of the country. As a result, the southwest monsoon becomes more vigorous, producing active monsoon conditions and above-normal rainfall.
  • On the other hand, when the suppressed phase of the MJO moves over the Indian Ocean, the atmosphere experiences downward movement of air, reducing cloud formation and rainfall.
  • During this period, India often witnesses breaks in the monsoon, where rainfall decreases significantly for several days despite the monsoon season being in progress. Such breaks can affect agricultural activities by reducing soil moisture and delaying crop growth.
  • The MJO also influences the onset and progress of the southwest monsoon. A strong active MJO phase over the Indian Ocean during late May or early June can support the timely onset and rapid advancement of the monsoon across the Indian subcontinent.
  • Conversely, if the active phase is located far away over the Pacific Ocean during this period, the onset may be delayed or the monsoon may initially remain weak.
  • Another important impact of the MJO is on extreme rainfall events. When its active phase coincides with other favourable weather systems such as low-pressure areas or monsoon depressions over the Bay of Bengal or the Arabian Sea, rainfall intensity can increase dramatically.
  • This may result in widespread flooding, landslides in mountainous regions, and urban flooding in major cities. Many episodes of exceptionally heavy monsoon rainfall in India have been linked to a strong active phase of the MJO.
  • The MJO also plays a crucial role in the formation and intensification of tropical cyclones over the Bay of Bengal and the Arabian Sea. During its active phase, the atmosphere becomes more unstable, humidity increases, and vertical wind conditions become more favourable for cyclone development.
  • Consequently, the probability of cyclogenesis and cyclone intensification rises when the active MJO is present over the northern Indian Ocean. In contrast, the suppressed phase generally inhibits cyclone formation by creating less favourable atmospheric conditions.
  • India's agricultural sector is particularly sensitive to the MJO because agriculture depends heavily on the distribution of monsoon rainfall.
  • An active MJO phase can provide beneficial rainfall for crops such as rice, cotton, sugarcane, and pulses. However, if the rainfall becomes excessive, it may damage standing crops through flooding and waterlogging. Similarly, an extended suppressed phase can reduce rainfall, leading to moisture stress and lower agricultural productivity.
  • The MJO also affects temperature patterns across India. During the active phase, increased cloud cover and rainfall generally reduce daytime temperatures and provide relief from heat. During the suppressed phase, clear skies allow greater solar heating, often resulting in hotter daytime conditions and, in some seasons, the development of heat waves.
  • Meteorologists in India, especially at the India Meteorological Department, closely monitor the MJO because it is one of the most reliable indicators for extended-range weather forecasting.
  • Since the MJO evolves over several weeks, it helps forecasters predict active and weak phases of the monsoon, the likelihood of heavy rainfall, and the potential for tropical cyclone formation about two to four weeks in advance.
  • This information is valuable for agriculture, water resource management, disaster preparedness, and reservoir operations.
 
 
4. What is the difference between Madden-Julian oscillation and ENSO?
 
 
 
  • The Madden–Julian Oscillation (MJO) and the El Niño–Southern Oscillation (ENSO) are two of the most important climate phenomena affecting global weather.
  • Although both originate in the tropical regions and influence rainfall, temperature, monsoons, and tropical cyclones, they differ significantly in their nature, duration, movement, and impacts.
  • Understanding these differences is essential for interpreting weather and climate variations across the world.
  • The Madden–Julian Oscillation is primarily an atmospheric phenomenon. It consists of a moving zone of enhanced and suppressed cloud formation and rainfall that travels eastward around the equator.
  • The MJO originates over the tropical Indian Ocean and usually moves across the maritime continent, the tropical Pacific Ocean, and sometimes into the Atlantic Ocean. The complete cycle generally takes 30 to 60 days, making it an intra-seasonal weather phenomenon.
  • In contrast, ENSO is a coupled ocean-atmosphere phenomenon. It develops due to changes in sea surface temperatures and atmospheric pressure across the equatorial Pacific Ocean. ENSO has three phases: El Niño, La Niña, and the neutral phase.
  • Unlike the MJO, ENSO does not move continuously around the globe. Instead, it remains centred over the equatorial Pacific Ocean and influences global climate through changes in ocean temperatures and atmospheric circulation.
  • An ENSO event typically lasts 9 to 12 months, although some events may continue for nearly two years.
  • Another major difference lies in the timescale. The MJO is a short-term oscillation that affects weather patterns over several weeks. Meteorologists use it to forecast rainfall, tropical cyclones, and monsoon activity two to four weeks in advance.
  • ENSO, on the other hand, operates over much longer periods and is used for seasonal climate forecasting, helping predict rainfall and temperature anomalies several months ahead.
  • The movement of these two phenomena also differs considerably. The MJO is a travelling disturbance that continuously propagates eastward around the equator.
  • Wherever its active phase passes, it enhances cloud formation, thunderstorms, and rainfall, while the following suppressed phase brings drier conditions.
  • ENSO does not travel in this manner. Instead, it represents large-scale warming (El Niño) or cooling (La Niña) of the central and eastern equatorial Pacific Ocean, with atmospheric circulation adjusting to these ocean temperature changes.
  • The influence of the two systems on the Indian monsoon is also different. A favourable active phase of the MJO over the Indian Ocean can strengthen the southwest monsoon for several weeks, leading to active monsoon spells and heavy rainfall.
  • However, once the MJO moves away, its influence diminishes. ENSO affects the overall seasonal strength of the monsoon. During El Niño years, India often experiences weaker monsoon rainfall and an increased likelihood of drought, while La Niña years generally favour stronger monsoon rainfall and wetter-than-normal conditions.
  • Although this relationship is not absolute, it remains one of the most important factors influencing India's seasonal rainfall.
  • The MJO also has a strong influence on tropical cyclone formation because its active phase creates favourable atmospheric conditions for cyclone development over the Indian Ocean, western Pacific, and other tropical basins.
  • ENSO also affects cyclone activity, but mainly by altering ocean temperatures and large-scale wind patterns over an entire cyclone season rather than over a few weeks.
  • An important distinction is that the MJO is primarily driven by changes in atmospheric convection, whereas ENSO is driven by interactions between the ocean and the atmosphere, especially variations in sea surface temperatures and trade winds across the Pacific Ocean.
  • Although they are different phenomena, the MJO and ENSO can interact with each other. For example, repeated strong MJO events can sometimes influence the evolution of El Niño or La Niña conditions by affecting westerly wind bursts over the Pacific Ocean.
  • Similarly, the background conditions created by ENSO can modify the strength and behaviour of the MJO.
 
5. Why is the Southwest Monsoon critical for Kharif agriculture in India?
 
 
  • The Southwest Monsoon is the backbone of India's agricultural economy and plays a decisive role in the success of the Kharif cropping season. Kharif crops are sown with the onset of the monsoon, generally during June and July, and harvested between September and October.
  • Since a large proportion of India's cultivated land is still dependent on rainfall rather than irrigation, the timing, amount, and distribution of monsoon rainfall directly determine agricultural productivity, food security, and rural livelihoods.
  • The southwest monsoon provides nearly 70–75% of India's annual rainfall, making it the primary source of water for agriculture.
  • As the monsoon winds reach the Indian subcontinent from the Arabian Sea and the Bay of Bengal, they bring widespread rainfall across most parts of the country.
  • This rainfall replenishes soil moisture, enabling farmers to prepare fields and sow Kharif crops such as rice, maize, cotton, soybean, groundnut, millets, pulses, and sugarcane.
  • The onset of the southwest monsoon marks the beginning of the Kharif agricultural season.
  • A timely arrival allows farmers to sow seeds at the optimum time, ensuring proper germination and healthy crop establishment. If the monsoon is delayed, sowing operations are postponed, shortening the growing season and often reducing crop yields. In severe cases, farmers may have to shift to short-duration or drought-resistant crop varieties.
  • Apart from the onset, the distribution of rainfall throughout the season is equally important. Crops require water at different stages of growth, including germination, vegetative growth, flowering, and grain filling.
  • Well-distributed rainfall ensures a continuous supply of moisture during these critical stages.
  • However, prolonged dry spells or breaks in the monsoon can lead to moisture stress, poor plant growth, and lower productivity.
  • Conversely, excessive rainfall within a short period can cause waterlogging, flooding, and root damage, affecting crop health and yield.
  • The southwest monsoon is particularly important because nearly half of India's net sown area remains rain-fed, despite significant expansion of irrigation facilities. Farmers in these regions rely almost entirely on monsoon rainfall.
  • Consequently, a good monsoon generally leads to higher agricultural production, while a weak or deficient monsoon often results in drought, crop failure, and financial distress among farming communities.
  • Monsoon rainfall also replenishes reservoirs, lakes, rivers, ponds, and groundwater aquifers, which provide irrigation water during the later stages of the Kharif season and for the subsequent Rabi cropping season. Adequate reservoir storage ensures sufficient water availability for irrigation, drinking water, hydropower generation, and industrial use throughout the year.
  • The performance of the Kharif season has a significant impact on India's food security. Crops such as rice and pulses constitute staple food items for millions of people.
  • A successful monsoon leads to higher food grain production, improved food availability, and stable market supplies. In contrast, poor monsoon performance may reduce agricultural output, creating supply shortages and increasing dependence on buffer stocks or imports.
  • The southwest monsoon also influences the Indian economy. Agriculture supports a substantial share of the country's population, particularly in rural areas. A normal monsoon generally increases farm incomes, boosts rural demand for goods and services, and supports overall economic growth.
  • Conversely, a deficient or erratic monsoon can reduce agricultural income, lower rural consumption, and adversely affect sectors such as fertilizers, farm machinery, consumer goods, and banking.
  • The monsoon has an important bearing on inflation, especially food inflation. Good rainfall usually leads to abundant production of cereals, vegetables, fruits, and pulses, helping stabilize food prices. On the other hand, deficient rainfall often reduces agricultural output, leading to higher food prices and contributing to overall inflationary pressures in the economy.
  • The southwest monsoon also supports allied activities such as animal husbandry, fisheries, and horticulture. Adequate rainfall improves pasture availability for livestock, replenishes ponds used in inland fisheries, and provides favourable conditions for the cultivation of fruits, vegetables, and plantation crops. Thus, its benefits extend well beyond crop production.
 
6. Way Forward
 
 
An IMD bulletin on Wednesday forecast low to moderate rainfall activity in the areas covered by the monsoon — which is only around half of the country’s landmass. Around this time in June, the monsoon normally covers almost the entire country.

ECOLOGICALLY SENSITIVE AREA (ESA)

 
 
1. Context
 
Twelve years after it issued the first draft notification, the Centre is finally ready to finalise and notify the demarcation of Ecologically Sensitive Areas (ESA) in the Western Ghats region, at least in the three states in which contentious issues have more or less been resolved
 
 
2. What is an ecologically sensitive area?
 
 
  • An Ecologically Sensitive Area (ESA) is a region that possesses unique and fragile environmental characteristics and therefore requires special protection from activities that could cause irreversible ecological damage.
  • These areas are rich in biodiversity, provide important ecosystem services, and often support rare or endangered species of plants and animals.
  • Because of their ecological significance, any developmental activities in such regions need to be carefully regulated to ensure that economic growth does not come at the cost of environmental degradation.
  • The idea behind declaring an area as ecologically sensitive is not to completely stop human activities, but to strike a balance between conservation and development.
  • Certain activities that can have severe environmental impacts—such as mining, quarrying, large-scale industries, thermal power plants, or extensive deforestation—are either prohibited or strictly regulated.
  • At the same time, sustainable activities like agriculture, horticulture, eco-tourism, and traditional livelihoods are generally encouraged so that local communities can continue to benefit from the resources without destroying them.
  • In India, the concept of Ecologically Sensitive Areas derives from the provisions of the Environment (Protection) Act, 1986. The Central Government can notify such areas to provide them with an additional layer of protection.
  • A notable example is the Western Ghats, one of the world's eight “hottest hotspots” of biodiversity.
  • Parts of the Western Ghats have been proposed and notified as Ecologically Sensitive Areas to preserve their rich flora and fauna, maintain water security, regulate climate, and ensure the long-term sustainability of the ecosystem
 
3. Which state has the highest number of ecologically sensitive zones in India?
 
  • Maharashtra has the highest number of Eco-Sensitive Zones (ESZs) in India. The Ministry of Environment, Forest and Climate Change (MoEFCC) has identified and notified the maximum number of ecologically sensitive zones in the state under the provisions of the Environment (Protection) Act, 1986.
  • This is primarily because Maharashtra has a large number of protected areas, including national parks, wildlife sanctuaries, and tiger reserves, many of which lie within the biodiversity-rich Western Ghats.
  • The state's varied landscapes and rich flora and fauna necessitate the creation of numerous buffer zones to protect these ecosystems from harmful developmental activities
 
4. Who declares ecologically sensitive areas?
 
 
  • The Forest Survey of India (FSI) is the apex national institution functioning under the Ministry of Environment, Forest and Climate Change (MoEFCC) and is entrusted with the periodic assessment and monitoring of the country’s forest resources.
  • Besides conducting forest inventories, the organization also undertakes training, research, and extension activities.
  • Established on June 1, 1981, FSI replaced the Pre-investment Survey of Forest Resources (PISFR), which had been launched in 1965 by the Government of India with support from the Food and Agriculture Organization (FAO) and the United Nations Development Programme (UNDP).
  • In November 2013, acting on the recommendations of the Kasturirangan Committee, the Central Government invoked the provisions of the Environment (Protection) Act, 1986 to restrict the establishment and expansion of activities such as mining, quarrying, sand extraction, thermal power projects, large-scale construction, townships, and highly polluting red-category industries.
  • The issuance of final Ecologically Sensitive Area (ESA) notifications further strengthens the legal framework aimed at safeguarding these environmentally fragile regions.
 
 
5. Which are the states where the areas to be demarcated as ESA?
 

The proposed Ecologically Sensitive Area (ESA) in the Western Ghats spans six states. Based on the recommendations of the Kasturirangan Committee, approximately 56,825 sq. km of the Western Ghats has been identified for demarcation as ESA. These states are:

  • Gujarat
  • Maharashtra
  • Goa
  • Karnataka
  • Kerala
  • Tamil Nadu

Among these, the largest proposed ESA area lies in Karnataka (20,668 sq. km), followed by Maharashtra (17,340 sq. km) and Kerala (about 9,993 sq. km)

 

6. Where do the Western Ghats stretch from?

 

  • The Western Ghats, also known as the Sahyadri Hills, form a continuous mountain chain running parallel to the western coast of India.
  • They stretch for about 1,600 kilometres from the Tapti (Tapi) River valley in Gujarat in the north to Kanyakumari in Tamil Nadu at the southern tip of the Indian peninsula.
  • Along their course, they pass through six states—Gujarat, Maharashtra, Goa, Karnataka, Kerala, and Tamil Nadu.
  • The mountain range covers an area of approximately 1,60,000 sq. km and acts as a major watershed, giving rise to several important peninsular rivers such as the Godavari, Krishna, Kaveri, and Tungabhadra.
  • Owing to their exceptional biodiversity and high degree of endemism, the Western Ghats are recognized as one of the world's eight "hottest hotspots" of biodiversity and have been designated as a UNESCO World Heritage Site
 
 
7. Significance of Western Ghats
 
The Western Ghats, a UNESCO World Heritage Site, hold immense ecological, climatic, cultural, and economic significance:
 
  • The Western Ghats are one of the world's eight "hottest hotspots" of biological diversity. They host over 7,400 species of flowering plants, 139 mammal species, 508 bird species, 179 amphibian species, 6,000 insect species, and 290 freshwater fish species, many of which are endemic.
  • A significant proportion of the species found in the Western Ghats are endemic, meaning they are not found anywhere else in the world. This includes many unique species of plants, animals, and microorganisms
  • The region provides crucial ecosystem services, such as water purification, climate regulation, soil stabilization, and carbon sequestration
  • The Western Ghats play a critical role in the Indian monsoon system. They intercept the moisture-laden winds from the southwest, causing heavy rainfall on the western side, which supports lush forests and agriculture
  • The forests of the Western Ghats act as a climate buffer, moderating temperatures and maintaining regional climate stability
  • The Western Ghats are the source of numerous rivers, including the Godavari, Krishna, and Cauvery, which provide water to millions of people in peninsular India. These rivers are crucial for drinking water, irrigation, and hydropower
  • The Western Ghats are home to numerous indigenous communities and tribal groups who have lived in harmony with the environment for centuries. These communities have rich cultural traditions and knowledge systems linked to the forests and biodiversity
  • Many areas in the Western Ghats are considered sacred by local communities and host numerous temples, shrines, and pilgrimage sites.
  • The Western Ghats support diverse agricultural systems, including spice plantations (pepper, cardamom), tea, coffee, and rubber. These crops are economically significant both domestically and for export
 
8.Way forward
 
Though the negotiations with Kerala and Karnataka are continuing, the Centre is learnt to be preparing to notify the ESA in the states where an agreement on this issue has either been achieved, or is close to being finalised. This is different from the previous attempts in which the Centre had issued draft notifications for ESAs in all the states together

LOGISTICS SUPPORT AGREEMENT (LSA)

 
 
 
1. Context
 
The India-Russia bilateral Logistics Support Agreement (LSA), termed the Reciprocal Exchange of Logistics Agreement (RELOS), which had been dragging on for several years, was operationalised in January this year. There was a flutter on social media recently with claims that it allows the stationing of 3,000 Russian troops on Indian soil or vice versa, painting it as a military alliance. However, it is like any LSA, the likes of which India has signed with other countries.
 
2. What are Logistics Support Agreements?
 
 
  • Logistics Support Agreements (LSAs) are basic defence cooperation arrangements between countries that facilitate the mutual use of military facilities such as bases and ports for refuelling, repairs, replenishment, and other logistical requirements.
  • These agreements are primarily administrative in nature and specify the circumstances under which such support may be extended, including joint military exercises, training activities, naval port visits, humanitarian assistance, and disaster relief operations.
  • With growing military-to-military engagement and strategic partnerships, LSAs help streamline procedures and minimise bureaucratic hurdles.
  • For example, India and the United States signed the Logistics Exchange Memorandum of Agreement (LEMOA) in 2016, which was India’s first logistics support pact of this kind.
  • The agreement establishes a framework for reciprocal access to logistics, supplies, and services during activities such as joint exercises, training programmes, and humanitarian or disaster relief missions.
  • Clarifying the scope of the agreement, then Minister of State for Defence Subhash Bhamre informed Parliament in February 2017 that LEMOA does not permit the establishment of military bases or any permanent basing arrangements.
  • Some exaggerated interpretations suggest that logistics agreements allow countries to station troops on each other’s territory.
  • Applying this logic, it is sometimes argued that if India and Russia could deploy forces on each other’s soil, India and the United States could do the same under LEMOA. However, such claims are incorrect.
  • As clarified by the Defence Ministry, logistics support agreements merely facilitate logistical cooperation and do not authorise the permanent deployment or stationing of troops, a principle that applies to all LSA
 
 
3. What is the Agreement with Russia?
 
 
  • Similar to other logistics support arrangements, the Reciprocal Exchange of Logistics Support (RELOS) agreement lays down the framework for providing assistance to military units, facilitating port visits by naval vessels, enabling the use of airspace and airfield infrastructure by military aircraft, and organising logistical and technical support for warships, aircraft, and other military equipment of both countries.
  • The agreement was concluded in Moscow on February 18, 2025, and was formally ratified after Russian President Vladimir Putin approved the corresponding federal law on December 15, 2025.
  • According to the Kremlin, the pact establishes procedures governing the deployment of military contingents, naval port calls, and the use of aviation infrastructure and airspace by the armed forces of India and Russia.
  • In broad terms, RELOS encompasses cooperation during joint exercises, training programmes, humanitarian assistance and disaster relief (HADR) operations, repair and maintenance facilities, medical assistance, supply of food and technical materials, and reciprocal access to military installations, including ports and airbases, to support personnel operating ships and aircraft.
  • The agreement specifies an upper ceiling of 3,000 personnel, which serves as a broad limit considering the size of military contingents and the number of ships or aircraft involved in mutually agreed engagements.
  • It remains in force for five years and allows for modifications in the future to accommodate evolving requirements. The duration for the deployment of personnel and equipment would depend on the nature and schedule of visits agreed upon by both countries.
  • In practice, India’s defence engagements with several countries are much more extensive. For example, Indian armed forces regularly participate in exercises with the United States and other partners.
  • Officials have clarified that RELOS does not provide for the permanent deployment of troops or military assets.
  • Its provisions are intended to be implemented only during agreed activities such as joint exercises, port visits, or other mutually approved engagements. No arrangement for permanent or long-term stationing forms part of the agreement.
  • A notable feature of RELOS is that it grants India access to Russian military facilities in the Arctic region.
  • This assumes greater significance as both countries seek to deepen cooperation in the Arctic, particularly in view of emerging navigation routes made increasingly accessible by climate change and global warming
 
 
4. Logistics Exchange Memorandum of Agreement (LEMOA)
 
 
  • The Logistics Exchange Memorandum of Agreement (LEMOA) is a bilateral logistics support arrangement signed between India and the United States in 2016.
  • It establishes a framework that enables the armed forces of both countries to access each other’s military facilities for refuelling, replenishment, repairs, and other logistical requirements on a reciprocal basis.
  • The agreement is intended to facilitate cooperation during joint military exercises, training activities, port visits, and humanitarian assistance and disaster relief (HADR) operations.
  • LEMOA simplifies administrative procedures and enhances interoperability between the two militaries by providing access to logistics supplies and services when required.
  • However, the agreement does not permit the establishment of military bases or permanent basing arrangements on each other’s territory.
  • This clarification was provided by the Government of India, which emphasized that the pact is purely logistical in nature and does not involve the stationing of troops or military assets.
  • As one of the key foundational defence agreements between India and the United States, LEMOA has strengthened strategic cooperation and improved the ability of both countries to undertake coordinated operations and respond effectively to regional and humanitarian contingencies
 
5. Logistics Support Agreements (LSAs) Signed by India with Various Countries
 
 

India has entered into several Logistics Support Agreements (LSAs) with strategic partners such as the United States, France, Australia, Japan, Singapore, and South Korea. These arrangements facilitate reciprocal access to military facilities and enhance defence cooperation, interoperability, and maritime security.

  • India–United States
 

As part of efforts to deepen defence relations, India and the United States have concluded three key foundational agreements:

  • Logistics Exchange Memorandum of Agreement (LEMOA), signed in 2016, enables the armed forces of both countries to access each other’s logistics infrastructure for refuelling, replenishment, maintenance, and other support services. The agreement significantly expands the operational reach of the Indian Navy. For instance, access to American facilities such as Guam enhances India's ability to sustain operations across distant waters.
  • Communications Compatibility and Security Agreement (COMCASA) was concluded in 2018. It facilitates the use of secure and encrypted communication systems, thereby enabling the effective deployment of advanced military platforms, including the P-8I maritime surveillance aircraft operated by the Indian Navy.
  • Basic Exchange and Cooperation Agreement (BECA), signed in November 2020, provides India with access to U.S. geospatial intelligence and satellite data. This improves the precision and targeting capability of long-range weapons and strengthens situational awareness.
  • India–France
  • The logistics agreement between India and France seeks to enhance strategic cooperation and contribute to peace and stability in the Indian and Pacific Oceans. It also enables closer collaboration between the two navies, including the exchange of maritime intelligence and improved operational coordination.
 
  • India–Australia
 
  • India and Australia signed the Mutual Logistics Support Agreement (MLSA) on June 4, 2020. Notably, it was the first bilateral agreement concluded through a virtual summit. The pact reflects the shared commitment of both countries to strengthening maritime cooperation and maintaining a free, open, and inclusive Indo-Pacific region.
 
  • India–Japan

 

  • In September 2020, India and Japan signed the Acquisition and Cross-Servicing Agreement (ACSA). The agreement facilitates reciprocal logistical support between the armed forces of the two nations and promotes closer defence cooperation in the Indo-Pacific.
 
  • India–Singapore

 

  • India and Singapore concluded a logistics support agreement on June 1, 2020. The arrangement covers a broad spectrum of military assets, including warships, submarines, aircraft, and shipborne helicopters, thereby enhancing naval cooperation between the two countries.
 
  • India–South Korea
  • India signed a Mutual Logistics Support Agreement with South Korea in September 2019. The agreement has expanded the operational footprint of the Indian Navy, extending its access and presence towards the northern reaches of the South China Sea and strengthening maritime engagement in East Asia.

 

 
 
7.  Way Forward
 
 
Overall, these logistics agreements have enhanced India's military interoperability with partner countries, expanded the operational reach of its armed forces, and reinforced its strategic presence across the Indo-Pacific region.

Although the partner countries differ, the underlying framework and objectives of these arrangements remain largely identical. They are intended to facilitate joint exercises, training activities, port visits, and other forms of military cooperation by simplifying access to logistical resources and support services.

In addition, India has a logistics support arrangement with Oman, which operates within the broader framework of the bilateral defence cooperation agreement between the two countries. Together, these agreements have enhanced the operational reach of the Indian armed forces and strengthened India's strategic partnerships across different regions.
