NIPAH VIRUS
- Nipah virus (NiV) is a zoonotic virus that can spread between animals and people.
- The natural host of NiV is fruit bats, also known as flying foxes.
- NiV can also infect pigs and people
- NiV infection can cause a range of illnesses, from asymptomatic infection to acute respiratory illness and fatal encephalitis. The case fatality rate for NiV infection is estimated to be between 40% and 75%
- The symptoms of NiV infection typically appear 4-14 days after exposure to the virus. The initial symptoms are similar to those of the flu, including fever, headache, and cough.
- In severe cases, the virus can cause encephalitis, which is a swelling of the brain. Encephalitis can lead to coma and death.
- NiV can be transmitted from animals to people through contact with infected saliva, urine, or other bodily fluids.
- It can also be transmitted through contact with contaminated food or water. Person-to-person transmission of NiV is possible, but it is rare.
- Nipah virus outbreaks have been reported in several countries in Southeast Asia, including Malaysia, Bangladesh, India, and Singapore.
- The virus has caused sporadic outbreaks, with varying levels of severity

- The first outbreaks of the Nipah virus among humans was reported from Malaysia (1998) and Singapore (1999).
- The virus takes its name from the village in Malaysia where the person in whom the virus was first isolated died of the disease.
- The transmission from animals happens mainly through consumption of contaminated food. According to the CDC, transmission can happen due to consumption of raw date palm sap or fruit that has been contaminated with saliva or urine from infected bats.
- Some cases of NiV [Nipah] infection have also been reported among people who climb trees where bats often roost.
- The animal host reservoir for this virus is known to be the fruit bat, commonly known as flying fox.
- Fruit bats are known to transmit this virus to other animals like pigs, and also dogs, cats, goats, horses and sheep
- Humans get infected mainly through direct contact with these animals, or through consumption of food contaminated by saliva or urine of these infected animals
- Since it was first identified in 1998-99, there have been multiple outbreaks of the Nipah virus, all of them in South and Southeast Asian nations. In Bangladesh, there have been at least 10 outbreaks since 2001.
In India, West Bengal had seen an outbreak in 2001 and 2007, while Kerala had reported several cases in 2018, and isolated cases in 2019 and 2021.
Zoonotic diseases, also known as zoonoses, are infectious diseases that can be transmitted between animals and humans. These diseases can be caused by bacteria, viruses, parasites, and fungi, and they pose a significant public health concern worldwide. Zoonotic diseases can be transmitted through direct or indirect contact with infected animals, their secretions, or contaminated environments. Some common examples of zoonotic diseases include:
-
Influenza: Various strains of influenza viruses can infect both animals and humans. Influenza viruses can undergo genetic changes, leading to new strains that have the potential to cause pandemics.
-
Rabies: Rabies is a viral disease that primarily affects mammals, including bats, dogs, and raccoons. It is transmitted to humans through the bite of an infected animal and can be fatal if not treated promptly.
-
Salmonellosis: Caused by the bacterium Salmonella, this disease is often associated with contaminated food products, particularly those of animal origin such as poultry and eggs.
-
Lyme Disease: Transmitted by ticks, Lyme disease is caused by the bacterium Borrelia burgdorferi and is commonly found in wildlife, particularly deer. Humans can become infected when bitten by an infected tick.
-
West Nile Virus: This mosquito-borne virus primarily circulates among birds but can be transmitted to humans through mosquito bites, leading to fever and, in some cases, severe neurological complications.
-
E. coli Infections: Certain strains of Escherichia coli (E. coli) can cause gastrointestinal illness in humans. Contaminated food and water, as well as contact with infected animals, can lead to E. coli infections.
-
HIV/AIDS: While the human immunodeficiency virus (HIV) is primarily transmitted among humans, it is believed to have originated from the transfer of simian immunodeficiency virus (SIV) from non-human primates to humans, making it a zoonotic disease.
-
COVID-19: The coronavirus disease 2019 (COVID-19) pandemic, caused by the novel coronavirus SARS-CoV-2, is believed to have originated in bats and was likely transmitted to humans through an intermediate animal host, highlighting the zoonotic nature of the virus.

Answer (A)
|
- The Maternal Mortality Rate (MMR) is a crucial indicator of the health status of women in a particular region or country.
- It represents the number of maternal deaths per 100,000 live births occurring due to complications related to pregnancy, childbirth, or the postpartum period.
- MMR reflects both the quality of maternal healthcare services and the overall health infrastructure in a given area.
- A high MMR indicates inadequate access to maternal healthcare, poor healthcare quality, and socioeconomic disparities, while a low MMR suggests effective maternal healthcare services and better health outcomes for women during pregnancy and childbirth.
3. What is Haemorrhage?
- Haemorrhage, often spelt as haemorrhage in American English, refers to the abnormal and excessive bleeding from blood vessels.
- It can occur internally, within the body, or externally, where blood flows out of the body.
- Haemorrhage can result from various causes, including trauma, injury, surgery, or underlying medical conditions such as blood vessel abnormalities, clotting disorders, or certain diseases.
- Depending on the severity and location of the haemorrhage, it can range from minor and self-limiting to life-threatening and requiring immediate medical intervention.
- Treatment for haemorrhage typically involves controlling the bleeding, stabilizing the patient, and addressing any underlying causes or complications.
4. Relation of women’s health to overall social development
Women's health is intricately linked to overall social development, impacting various aspects of society.
Improved Health Outcomes
- Lower maternal mortality rates (MMR) signify better access to quality healthcare for women during pregnancy and childbirth. This translates to healthier families and fewer tragedies.
- Healthy mothers are more likely to give birth to healthy babies and provide them with proper care during infancy and childhood, leading to a healthier next generation.
- Better healthcare for women leads to a longer lifespan, allowing them to contribute more actively to society and families for a longer duration.
Socioeconomic Benefits
- When women are healthy, they are more likely to pursue education and participate in the workforce, contributing to economic growth and development.
- A healthy female population translates to a more productive workforce, boosting the overall economic output of a nation.
- When women can earn a living and care for their families' health, it helps break the cycle of poverty and improves the overall well-being of the community.
Social Fabric and Stability
- Improved access to family planning services and reproductive health education can lead to smaller families, allowing for better resource allocation and investment in children's health and education.
- Healthy mothers are better equipped to raise healthy and well-educated children, fostering stronger and more stable families, which are the building blocks of a healthy society.
- Women play a crucial role in community development initiatives like education, sanitation, and healthcare. Their good health allows them to contribute more effectively to these areas.
Investing in Women's Health
- Prioritizing women's health is not just a moral imperative but also a smart investment in a nation's future.
- By addressing issues like maternal mortality, access to healthcare, and reproductive health education, countries can create a healthier, more productive, and prosperous society for all.
5. Why are women at risk of heart disease?
Women are susceptible to heart disease, even though it's often perceived as a man's health issue.
Biological Differences
- Estrogen, a female sex hormone, has a protective effect on the heart before menopause. However, estrogen levels decline after menopause, removing this protective layer and increasing the risk of heart disease.
- Women typically have smaller hearts and coronary arteries compared to men. This can make them more susceptible to blockages and blood flow issues even with less plaque buildup.
- Certain pregnancy complications like gestational diabetes or preeclampsia can increase the long-term risk of heart disease in women.
Risk Factors
Many traditional risk factors for heart disease apply to both men and women, but some pose a greater threat to women.
- Uncontrolled high blood pressure and cholesterol levels significantly increase the risk of heart disease in both men and women. However, women tend to have higher LDL ("bad") cholesterol and lower HDL ("good") cholesterol levels compared to men, putting them at a disadvantage.
- Diabetes is a major risk factor for heart disease, and women with diabetes are more likely than men to develop heart disease complications.
- A sedentary lifestyle and obesity are significant contributors to heart disease. While these are concerns for both genders, women are more likely to face societal pressures that discourage physical activity and contribute to weight gain.
- Women are more prone to chronic stress and depression, which can elevate blood pressure and weaken the immune system, increasing the risk of heart disease.
- Heart disease symptoms in women can sometimes be different from those experienced by men. Women may experience pain in the back, jaw, or upper abdomen instead of the classic chest pain associated with heart attacks. This can lead to misdiagnosis and delayed treatment.
Preventive Measures
The good news is that heart disease is largely preventable. By adopting a healthy lifestyle, women can significantly reduce their risk.
- Regular exercise and a balanced diet are crucial for weight management and overall heart health.
- Regular checkups and adherence to medications are essential for controlling blood pressure and cholesterol levels.
- Techniques like yoga, meditation, or spending time in nature can help manage stress and improve overall well-being.
- Educating yourself about the different symptoms of heart disease in women can ensure you seek timely medical attention.
6. The steps taken by the government to reduce MMR
The government of India have implemented various strategies to reduce the Maternal Mortality Ratio (MMR).
Improving Access to Antenatal, Intranatal, and Postnatal Care
- Encouraging women to give birth in medical facilities with skilled birth attendants significantly reduces the risk of complications and fatalities during childbirth. This can involve initiatives like
-
- Janani Suraksha Yojana (JSY) scheme in India that provides financial assistance to pregnant women delivering in public health institutions.
- Educating women about the benefits of institutional deliveries and addressing potential fears or cultural barriers.
- Ensuring a sufficient number of trained midwives, nurses, and doctors to handle deliveries and manage potential complications is crucial.
- Providing regular checkups, screenings, and essential nutrients during pregnancy helps identify and manage potential risks for both mother and baby.
- Offering healthcare support to mothers and newborns after delivery helps address postpartum complications like infections and haemorrhage.
Addressing Underlying Risk Factors
- Ensuring proper nutrition for women, especially before and during pregnancy, is critical for a healthy pregnancy and reduces the risk of complications.
- Providing access to family planning services allows women to plan their pregnancies and space them appropriately, improving maternal health outcomes.
- Teenage pregnancies are at a higher risk of complications. Educating young girls about sexual health and reproductive rights can help reduce teenage pregnancies and improve MMR.
Strengthening Healthcare Systems
- Upgrading healthcare facilities, especially in rural areas, with essential equipment and supplies is essential for providing quality maternal care.
- Ensuring timely access to emergency obstetric care can save lives in case of complications during childbirth.
- Monitoring MMR data and identifying areas with high rates allows for targeted interventions and resource allocation.
Community Engagement
- Educating women about their rights, including their right to quality healthcare, and encouraging them to seek timely medical attention are crucial steps.
- Engaging community leaders and involving men in promoting maternal health awareness can create a supportive environment for women.
The Sustainable Development Goals (SDGs) adopted by the United Nations in 2015 address a wide range of global challenges and one of them is directly related to Maternal Mortality Ratio (MMR).
Target 3.1: Reduce Maternal Mortality Ratio
SDG Goal 3 focuses on ensuring healthy lives and promoting well-being for all at all ages. Within this goal, Target 3.1 specifically targets the reduction of MMR. It aims to
- Reduce the global maternal mortality ratio to less than 70 per 100,000 live births by 2030.
- No country should have an MMR greater than 140 per 100,000 live births.
SDGs Support Reducing MMR
Other SDGs indirectly contribute to achieving Target 3.1 by addressing factors that can influence MMR
- SDG 1 (No Poverty): Poverty is a major risk factor for poor maternal health outcomes. By alleviating poverty, women have better access to healthcare and nutritious food.
- SDG 2 (Zero Hunger): Malnutrition is another risk factor. Ensuring food security and improved nutrition can improve maternal health.
- SDG 4 (Quality Education) Educated women are more likely to make informed choices about their health and seek prenatal care.
- SDG 5 (Gender Equality) Empowering women and ensuring their access to education and healthcare services are crucial for improving maternal health outcomes.
- SDG 6 (Clean Water and Sanitation) Access to clean water and sanitation facilities helps prevent infections, which can be a major cause of maternal mortality.

LINE OF ACTUAL CONTROL (LAC)

The eastern sector which spans Arunachal Pradesh and Sikkim,
The middle sector in Uttarakhand and Himachal Pradesh, and the western sector in Ladakh
|
- The alignment of the LAC in the eastern sector is along the 1914 McMahon Line, and there are minor disputes about the positions on the ground as per the principle of the high Himalayan watershed
- This pertains to India’s international boundary as well, but for certain areas such as Longju and Asaphila
- The line in the middle sector is the least controversial but for the precise alignment to be followed in the Barahoti plains.
- The major disagreements are in the western sector where the LAC emerged from two letters written by Chinese Prime Minister Zhou Enlai to PM Jawaharlal Nehru in 1959, after he had first mentioned such a ‘line’ in 1956.
- In his letter, Zhou said the LAC consisted of “the so-called McMahon Line in the east and the line up to which each side exercises actual control in the west”
- After the 1962 War, the Chinese claimed they had withdrawn to 20 km behind the LAC of November 1959
- During the Doklam crisis in 2017, the Chinese Foreign Ministry spokesperson urged India to abide by the “1959 LAC”
- India rejected the concept of LAC in both 1959 and 1962. Even during the war, Nehru was unequivocal: “There is no sense or meaning in the Chinese offer to withdraw twenty kilometres from what they call ‘line of actual control’
- LAC was discussed during Chinese Premier Li Peng’s 1991 visit to India, where PM P V Narasimha Rao and Li reached an understanding to maintain peace and tranquillity at the LAC.
- India formally accepted the concept of the LAC when Rao paid a return visit to Beijing in 1993 and the two sides signed the Agreement to Maintain Peace and Tranquillity at the LAC
- The reference to the LAC was unqualified to make it clear that it was not referring to the LAC of 1959 or 1962 but to the LAC at the time when the agreement was signed
- To reconcile the differences about some areas, the two countries agreed that the Joint Working Group on the border issue would take up the task of clarifying the alignment of the LAC
The LoC emerged from the 1948 ceasefire line negotiated by the UN after the Kashmir War. It was designated as the LoC in 1972, following the Shimla Agreement between the two countries. It is delineated on a map signed by DGMOs of both armies and has the international sanctity of a legal agreement.
The LAC, in contrast, is only a concept – it is not agreed upon by the two countries, neither delineated on a map or demarcated on the ground.

BRAHMOS MISSILE
- The BrahMos missile is a supersonic cruise missile jointly developed by India's Defence Research and Development Organisation (DRDO) and Russia's NPO Mashinostroyeniya. Its name is a portmanteau of the Brahmaputra and Moskva rivers.
- BrahMos is known for its speed and versatility. It is the fastest cruise missile in the world, capable of reaching speeds of up to Mach 3 (three times the speed of sound). This makes it extremely difficult for enemy defenses to intercept.
- The missile has both land-attack and anti-ship capabilities, meaning it can target both land-based targets and naval vessels. Its precision and range make it a potent weapon for both offensive and defensive purposes. It's deployed across various platforms including land, sea, and air.
- The BrahMos missile has become a significant asset in the Indian military's arsenal, providing a formidable deterrent and offensive capability. It's continuously being upgraded to enhance its capabilities and adapt it to different platforms and operational requirements
3. Evolution of Brahmos
- During the early 1980s, Dr. A P J Abdul Kalam spearheaded the Integrated Guided Missile Development Programme, initiating the creation of various indigenous missiles such as Prithvi, Agni, Trishul, Akash, and Nag, each with diverse capabilities and operational ranges.
- In the early 1990s, India's strategic leadership recognized the necessity for cruise missiles—guided projectiles maintaining nearly constant speeds throughout their trajectories—to deliver sizable warheads with pinpoint accuracy over extensive distances.
- This requirement emerged prominently following the deployment of cruise missiles during the 1991 Gulf War.
- In 1998, an Inter-Governmental Agreement was formalized in Moscow between Dr. Kalam, then heading the DRDO, and N V Mikhailov, Russia's Deputy Defence Minister at the time.
- This agreement laid the foundation for BrahMos Aerospace, a collaborative venture between DRDO and the Russian space company NPO Mashinostroyenia (NPOM), with the Indian side holding 50.5% ownership and the Russians 49.5%. The venture derived its name from two rivers—Brahmaputra in India and Moskva in Russia.
- Subsequently, in 1999, the development of missiles commenced within the laboratories of DRDO and NPOM after BrahMos Aerospace secured funding from both governments. The first successful test launch occurred in 2001 from a specifically engineered land-based launcher
4.Significance of Brahmos
- The BrahMos missile is equipped with a solid propellant booster engine, comprising two stages. Initially, the first stage accelerates the missile to supersonic speeds, after which it detaches. Subsequently, the liquid ramjet, constituting the second stage, propels the missile to nearly three times the speed of sound during its cruise phase.
- Notably, the missile exhibits a minimal radar signature, enhancing its stealth capabilities, and can follow various trajectories.
- As a "fire and forget" weapon, it can maintain a cruising altitude of 15 km and descend to as low as 10 meters to effectively strike its target.
- Classified as "standoff range weapons," cruise missiles like BrahMos are launched from a distance substantial enough to evade defensive countermeasures, a feature common among the arsenals of major militaries worldwide.
- Compared to subsonic cruise missiles, BrahMos boasts three times the speed, 2.5 times the flight range, and extended operational capabilities. With export versions available, BrahMos serves as a crucial asset in defense diplomacy initiatives.
- In 2022, an air-launched variant of BrahMos underwent testing from a frontline SU-30MKI aircraft, while an advanced sea-to-sea variant was also tested from the INS Visakhapatnam during the same year.
- However, BrahMos was embroiled in controversy in 2022 when Pakistan alleged that an unarmed Indian missile had inadvertently landed within its territory on March 9, 2022. The Ministry of Defence attributed the incident to a technical malfunction resulting in accidental firing.
- Though the government initiated a high-level inquiry, the specific missile involved was not officially disclosed. Nonetheless, experts inferred from its trajectory that it bore the hallmarks of BrahMos
5. Types of BrahMos
- The BrahMos missile system is strategically deployed across various fronts, encompassing land-based formations along border regions, BrahMos-equipped Sukhoi-30 aircraft stationed in both the Northern and Southern theaters, and ships and submarines fitted with BrahMos capabilities in naval operations. This integrated setup constitutes a formidable triad, adept at addressing evolving demands in multidimensional warfare scenarios.
- To adapt to dynamic warfare requirements, ongoing efforts are focused on upgrading the BrahMos system, with emphasis on enhancing range, maneuverability, and accuracy.
- Current development initiatives include testing versions with extended ranges of up to 350 km, surpassing the original's 290 km limit. Furthermore, plans are underway for versions with even greater ranges, potentially reaching up to 800 km, and featuring hypersonic speeds. Concurrently, endeavors are directed towards reducing the size and radar signature of existing iterations while augmenting their overall capabilities.
- Across all three branches of the Armed Forces, BrahMos variants are subject to regular testing, including those presently in development.
- Land-Based: The land-based BrahMos setup comprises mobile autonomous launchers, typically housing four to six launchers, each armed with three missiles capable of near-simultaneous firing.
- These batteries are strategically deployed along India's land borders in various theaters. Upgraded versions of the land attack variant, capable of cruising at 2.8 Mach, boast precision striking capabilities with ranges of up to 400 km.
- Advanced iterations with enhanced range and speeds of up to 5 Mach are reportedly in the developmental pipeline. Notably, the ground systems of BrahMos are lauded for their streamlined design and minimal componentry.
- Ship-Based: Since 2005, the Navy has been inducting BrahMos missiles on its frontline warships, enhancing their ability to engage sea-based targets beyond the radar horizon. The naval variant has demonstrated efficacy in both sea-to-sea and sea-to-land engagements.
- These missiles can be deployed individually or in salvos of up to eight, with staggered firing intervals. This capability enables them to effectively target groups of frigates equipped with modern missile defense systems.
- Air-Launched: The successful flight testing of BrahMos from a Sukhoi-30MKI against a sea-based target in the Bay of Bengal on November 22, 2017, marked a significant milestone. Subsequent tests have validated its effectiveness.
- The BrahMos-equipped Sukhoi-30 aircraft, boasting a range of 1,500 km without mid-air refueling, serve as a pivotal strategic deterrent along both land borders and the strategically vital Indian Ocean Region. The Indian Air Force is actively integrating BrahMos with 40 Sukhoi-30 fighter jets across various airbases.
- Submarine-Launched: This variant can be launched from depths of approximately 50 meters below the water surface. The missile, stored in a canister, is vertically launched from the pressure hull of the submarine, employing distinct configurations for underwater and surface flights. Successful testing of this version was first conducted in March 2013 from a submerged platform off the coast of Visakhapatnam
6. Brahmos Missile Series
The BrahMos missile series is a family of supersonic cruise missiles developed jointly by India and Russia. Named after the Brahmaputra River in India and the Moskva River in Russia, the BrahMos series is renowned for its speed, precision, and versatility.

Previous Year Questions
1.Consider the following statements: (UPSC CSE Prelims 2023)
Which of the statements given above is/are correct?
Answer: (d) |
IMF BAILOUT
1. Context
2. Why are Sri Lanka and Pakistan facing major macroeconomic risks?
- Sri Lanka's macroeconomic landscape has been characterized by fiscal dominance-high deficits and public debt.
- This has manifested in a high degree of macroeconomic volatility, evidenced by its frequent balance-of-payments crises and instability.
- Macroeconomic risks also remain high as Pakistan faces challenges associated with a large current account deficit, high public debt, and lower demand from its traditional export markets amid subdued global growth.
3. How do currency devaluation and price rise affect an economy?
- Exports are cheaper to foreign customers
- Imports are more expensive.
- In the short term, a devaluation tends to cause inflation, higher growth, and increased demand for exports.
4. Effects of Devaluation
.png)
5. International Monetary Fund (IMF)
- The International Monetary Fund (IMF) is an organization of 189 member countries, each of which has representation on the IMF's executive board in proportion to its financial importance so that the most powerful countries in the global economy have the most voting power.
- The IMF, also known as the Fund, was conceived at a UN conference in Bretton Woods, New Hampshire, United States, in July 1944.
- The 44 countries at that conference sought to build a framework for economic cooperation to avoid a repetition of the competitive devaluations that had contributed to the Great Depression of the 1930s.
- Countries were not eligible for membership in the International Bank for Reconstruction and Development (IBRD) unless they were members of the IMF.
6. Functions of IMF
- Regulatory functions: IMF functions as a regulatory body and as per the rules of the Articles of Agreement, it also focuses on administering a code of conduct for exchange rate policies and restrictions on payments for current account transactions.
- Financial functions: IMF provides financial support and resources to the member countries to meet short-term and medium-term Balance of Payments (BOP) disequilibrium.
- Consultative functions: IMF is a center for international cooperation for the member countries. It also acts as a source of counsel and technical assistance.
7. Special Drawing Rights (SDR)
- Special Drawing Rights (SDRs) are supplementary foreign exchange reserve assets defined and maintained by the International Monetary Fund (IMF).
- SDR is not a currency, instead represents a claim to currency held by IMF member countries for which they may be exchanged.
- The value of an SDR is defined by a weighted currency basket of four major currencies- the US dollar, the Euro, the British Pound, the Chinese Yuan, and the Japanese Yen.
- Central Bank of member countries held SDR with IMF which can be used by them to access funds from IMF in case of financial crises in their domestic market.
8. Why do nations seek an IMF bailout?
- Countries seek help from the IMF usually when their economies face a major macroeconomic risk, mostly in the form of a currency crisis.
- For instance, in the case of Sri Lanka and Pakistan, both countries have witnessed domestic prices rise rapidly and the exchange value of their currencies drop steeply against the U.S. dollar.
- Such currency crises are generally the result of gross mismanagement of the nation's currency by its central bank, often under the covert influence of the ruling government.
- A rapid unpredictable fall in the value of a currency can destroy confidence is said currency and affect economic activity as people may turn hesitant to accept the currency in exchange for goods and services.
- Foreigners may also be unwilling to invest in an economy where the value of its currency gyrates in an unpredictable manner.
- In such a scenario, many countries are forced to seek help from the IMF to meet their external debt and other obligations, purchase essential imports, and also to prop up the exchange value of their currencies.
9. How does the IMF help Countries?
- The IMF basically lends money, often in the form of special drawing rights (SDRs), to troubled economies that seek the lender's assistance.
- SDRs simply represent a basket of currencies namely the U.S. dollar, the euro, the Chinese Yuan, the Japanese Yen, and the British Pound.
- The IMF carries out its lending to troubled economies through a number of lending programs such as the extended credit facility, the flexible credit line, the standby agreement, etc.
- Countries receiving the bailout can use the SDRs for various purposes depending on their individual circumstances.
- Currently, both Sri Lanka and Pakistan are in urgent need of U.S. dollars to import essential items and also to pay their foreign debt.
- So any money that they receive from the IMF is likely to go towards addressing these urgent issues.
10. IMF Lending Instruments
- The IMF's various lending instruments are tailored to different types of balance of payments need as well as the specific circumstances of its diverse.
- All IMF members are eligible to access to Fund's resources in the General Resources Account (GRA) on non-concessional terms.
- The IMF also provides concessional financial support (currently at zero interest rates through June 2021) through the Poverty Reduction and Growth Trust which is better tailored to the diversity and needs of low-income countries.
- Historically, for emerging and advanced market economies in crises, the bulk of IMF assistance has been provided through stand-by agreements (SBAs) to address the short-term or potential balance of payments problems.
- The Standby Credit Facility (SCF) serves a similar purpose for low-income countries.
- The External Fund Facility (EFF) and the corresponding Extended Credit Facility (ECF) for low-income countries are the Fund's main tools for medium-term support to countries facing protracted balance of payments problems.
- To help prevent or mitigates crises and boost market confidence during periods of heightened risks, members with already strong policies can use the Flexible Credit Line (FCL) or the Precautionary and Liquidity Line (PLL).

BRAHMOS MISSILE
- The BrahMos missile is a supersonic cruise missile jointly developed by India's Defence Research and Development Organisation (DRDO) and Russia's NPO Mashinostroyeniya. Its name is a portmanteau of the Brahmaputra and Moskva rivers.
- BrahMos is known for its speed and versatility. It is the fastest cruise missile in the world, capable of reaching speeds of up to Mach 3 (three times the speed of sound). This makes it extremely difficult for enemy defenses to intercept.
- The missile has both land-attack and anti-ship capabilities, meaning it can target both land-based targets and naval vessels. Its precision and range make it a potent weapon for both offensive and defensive purposes. It's deployed across various platforms including land, sea, and air.
- The BrahMos missile has become a significant asset in the Indian military's arsenal, providing a formidable deterrent and offensive capability. It's continuously being upgraded to enhance its capabilities and adapt it to different platforms and operational requirements
3. Evolution of Brahmos
- During the early 1980s, Dr. A P J Abdul Kalam spearheaded the Integrated Guided Missile Development Programme, initiating the creation of various indigenous missiles such as Prithvi, Agni, Trishul, Akash, and Nag, each with diverse capabilities and operational ranges.
- In the early 1990s, India's strategic leadership recognized the necessity for cruise missiles—guided projectiles maintaining nearly constant speeds throughout their trajectories—to deliver sizable warheads with pinpoint accuracy over extensive distances.
- This requirement emerged prominently following the deployment of cruise missiles during the 1991 Gulf War.
- In 1998, an Inter-Governmental Agreement was formalized in Moscow between Dr. Kalam, then heading the DRDO, and N V Mikhailov, Russia's Deputy Defence Minister at the time.
- This agreement laid the foundation for BrahMos Aerospace, a collaborative venture between DRDO and the Russian space company NPO Mashinostroyenia (NPOM), with the Indian side holding 50.5% ownership and the Russians 49.5%. The venture derived its name from two rivers—Brahmaputra in India and Moskva in Russia.
- Subsequently, in 1999, the development of missiles commenced within the laboratories of DRDO and NPOM after BrahMos Aerospace secured funding from both governments. The first successful test launch occurred in 2001 from a specifically engineered land-based launcher
4.Significance of Brahmos
- The BrahMos missile is equipped with a solid propellant booster engine, comprising two stages. Initially, the first stage accelerates the missile to supersonic speeds, after which it detaches. Subsequently, the liquid ramjet, constituting the second stage, propels the missile to nearly three times the speed of sound during its cruise phase.
- Notably, the missile exhibits a minimal radar signature, enhancing its stealth capabilities, and can follow various trajectories.
- As a "fire and forget" weapon, it can maintain a cruising altitude of 15 km and descend to as low as 10 meters to effectively strike its target.
- Classified as "standoff range weapons," cruise missiles like BrahMos are launched from a distance substantial enough to evade defensive countermeasures, a feature common among the arsenals of major militaries worldwide.
- Compared to subsonic cruise missiles, BrahMos boasts three times the speed, 2.5 times the flight range, and extended operational capabilities. With export versions available, BrahMos serves as a crucial asset in defense diplomacy initiatives.
- In 2022, an air-launched variant of BrahMos underwent testing from a frontline SU-30MKI aircraft, while an advanced sea-to-sea variant was also tested from the INS Visakhapatnam during the same year.
- However, BrahMos was embroiled in controversy in 2022 when Pakistan alleged that an unarmed Indian missile had inadvertently landed within its territory on March 9, 2022. The Ministry of Defence attributed the incident to a technical malfunction resulting in accidental firing.
- Though the government initiated a high-level inquiry, the specific missile involved was not officially disclosed. Nonetheless, experts inferred from its trajectory that it bore the hallmarks of BrahMos
5. Types of BrahMos
- The BrahMos missile system is strategically deployed across various fronts, encompassing land-based formations along border regions, BrahMos-equipped Sukhoi-30 aircraft stationed in both the Northern and Southern theaters, and ships and submarines fitted with BrahMos capabilities in naval operations. This integrated setup constitutes a formidable triad, adept at addressing evolving demands in multidimensional warfare scenarios.
- To adapt to dynamic warfare requirements, ongoing efforts are focused on upgrading the BrahMos system, with emphasis on enhancing range, maneuverability, and accuracy.
- Current development initiatives include testing versions with extended ranges of up to 350 km, surpassing the original's 290 km limit. Furthermore, plans are underway for versions with even greater ranges, potentially reaching up to 800 km, and featuring hypersonic speeds. Concurrently, endeavors are directed towards reducing the size and radar signature of existing iterations while augmenting their overall capabilities.
- Across all three branches of the Armed Forces, BrahMos variants are subject to regular testing, including those presently in development.
- Land-Based: The land-based BrahMos setup comprises mobile autonomous launchers, typically housing four to six launchers, each armed with three missiles capable of near-simultaneous firing.
- These batteries are strategically deployed along India's land borders in various theaters. Upgraded versions of the land attack variant, capable of cruising at 2.8 Mach, boast precision striking capabilities with ranges of up to 400 km.
- Advanced iterations with enhanced range and speeds of up to 5 Mach are reportedly in the developmental pipeline. Notably, the ground systems of BrahMos are lauded for their streamlined design and minimal componentry.
- Ship-Based: Since 2005, the Navy has been inducting BrahMos missiles on its frontline warships, enhancing their ability to engage sea-based targets beyond the radar horizon. The naval variant has demonstrated efficacy in both sea-to-sea and sea-to-land engagements.
- These missiles can be deployed individually or in salvos of up to eight, with staggered firing intervals. This capability enables them to effectively target groups of frigates equipped with modern missile defense systems.
- Air-Launched: The successful flight testing of BrahMos from a Sukhoi-30MKI against a sea-based target in the Bay of Bengal on November 22, 2017, marked a significant milestone. Subsequent tests have validated its effectiveness.
- The BrahMos-equipped Sukhoi-30 aircraft, boasting a range of 1,500 km without mid-air refueling, serve as a pivotal strategic deterrent along both land borders and the strategically vital Indian Ocean Region. The Indian Air Force is actively integrating BrahMos with 40 Sukhoi-30 fighter jets across various airbases.
- Submarine-Launched: This variant can be launched from depths of approximately 50 meters below the water surface. The missile, stored in a canister, is vertically launched from the pressure hull of the submarine, employing distinct configurations for underwater and surface flights. Successful testing of this version was first conducted in March 2013 from a submerged platform off the coast of Visakhapatnam
