Over 160 Killed by Lightning in March-April 2025 Syllabus: GS1/ Geography Between March and mid-April 2025, 162 people tragically lost their lives due to lightning strikes across 12 Indian states. The worst-hit region was Bihar, which recorded 99 deaths, accounting for 61% of the national total, followed by Uttar Pradesh. What is Lightning? Lightning is an electrical discharge that occurs between charged particles in a cloud and the ground. When the voltage in the atmosphere reaches approximately 3 million volts per meter, the air’s insulating properties break down, allowing a powerful electric current to flow. This results in a sudden burst of energy, creating a bright flash of light and a thunderous sound.   How Does Lightning Develop? Several factors contribute to the development of lightning, including: High humidity in regions like eastern states and coastal areas, which promotes thunderstorms. Topographical features like the Himalayas and Western Ghats, influencing lightning frequency. Monsoon dynamics, where moist air rises, driving thunderstorms and lightning. Rapid urbanization and industrialization, which increase the occurrence of artificial heat sources and aerosols that enhance thunderstorms. Climate change, which alters weather patterns and potentially increases the frequency and intensity of lightning events. Agricultural practices, such as burning agricultural residues, which add particulates to the atmosphere and heighten the risk of thunderstorms.   Government Initiatives To mitigate the risks posed by lightning, several government efforts have been made: The CROPC (Climate Resilient Observing Systems Promotion Council) developed India’s first Lightning Early Warning System to predict lightning strikes and issue alerts. The SACHET mobile app was launched to provide timely lightning hazard alerts to the public. In 2020, the Damini Lightning App was developed by the Indian Institute of Tropical Meteorology (IITM) to track lightning strikes and raise awareness.   Moving Forward To reduce lightning fatalities, it is crucial to: Strengthen communication systems so that warnings reach vulnerable populations efficiently. Train local authorities to act swiftly based on early warnings. Increase public awareness about lightning safety, especially during the pre-monsoon and monsoon seasons. Improve ground-level implementation of NDMA (National Disaster Management Authority) protocols to minimize the impact and save lives. With these measures in place, we hope to reduce the devastating impact of lightning and protect more lives in the future. Consider the following factors contributing to the increased frequency of lightning strikes in India: High humidity in coastal areas and eastern states. The orographic effect caused by the Himalayas and Western Ghats. Increased aerosol concentration due to urbanization and industrialization. The effect of global warming on atmospheric convection and storm dynamics. Which of the factors listed above is/are most directly responsible for the increased frequency and intensity of lightning strikes in India? a) 1 and 2 onlyb) 2, 3, and 4 onlyc) 1, 2, and 3 onlyd) 1, 2, 3, and 4 Answer: d) 1, 2, 3, and 4 Explanation:All the factors listed contribute significantly to the increased frequency of lightning strikes. High humidity in coastal and eastern regions promotes thunderstorms, which often result in lightning. Orographic lifting in regions like the Himalayas and Western Ghats leads to intense storm formations and lightning. Urbanization and industrialization increase the concentration of aerosols in the atmosphere, enhancing cloud formation and intensifying lightning events. Climate change alters temperature and moisture dynamics, further driving more intense lightning occurrences. World Bank: India’s Extreme Poverty Drops to 2.3% Syllabus :GS 3/Economy  According to the World Bank’s Poverty and Equity Briefs (PEBs), India has made remarkable strides in reducing extreme poverty, with the proportion of people living in extreme poverty dropping from 16% in 2011–12 to just 2.3% in 2022–23. This substantial reduction represents a major milestone in the country’s ongoing efforts to combat poverty.   About the Poverty and Equity Briefs (PEBs) The Poverty and Equity Briefs (PEBs) are biannual reports published by the World Bank. These reports provide a snapshot of trends in poverty, inequality, and shared prosperity across over 100 developing countries. The PEBs are released during the Spring and Annual Meetings of the World Bank and the International Monetary Fund (IMF). Their goal is to keep the issue of poverty reduction central to global policy discussions.   Key Indicators and Measurement The PEBs track several important indicators to assess poverty and inequality: Poverty rates based on both national and international poverty lines (e.g., $2.15/day in 2017 PPP terms, $3.65 for lower-middle-income countries, and $6.85 for upper-middle-income countries). The Multidimensional Poverty Index (MPI), which considers deprivations in areas such as education, basic services, and nutrition in addition to income poverty. Inequality is measured using the Gini Index, a tool that gauges income or consumption inequality in a population.   India’s Recent Poverty Trends (2022–23) India has witnessed a sharp decline in extreme poverty, with significant reductions across both rural and urban areas: Extreme poverty, measured at $2.15 per day (PPP), fell from 16% in 2011–12 to 3% in 2022–23, lifting 171 million people above the poverty line. Rural areas saw a drop in extreme poverty from 4% to 2.8%, while urban areas experienced a decline from 10.7% to 1.1%, significantly narrowing the rural-urban poverty gap. When measured against the $3.65/day threshold for lower-middle-income countries, poverty declined from 8% to 28.1%, with an additional 378 million people moving above this line. The Multidimensional Poverty Index (MPI), which includes factors such as education and basic services, showed a significant decrease in non-monetary poverty, dropping from 53.8% in 2005–06 to 15.5% in 2022–23.   Regional Distribution of Poverty India’s most populous states—Uttar Pradesh, Maharashtra, Bihar, West Bengal, and Madhya Pradesh—continue to account for a large portion of the country’s poverty: These five states accounted for 54% of India’s extreme poor in 2022–23, and 51% of the multidimensionally poor in 2019–21. Despite making significant strides, these states still represent a key focus area for poverty alleviation efforts, although they have also driven much of India’s poverty reduction, contributing to two-thirds of the overall decline.   Inequality and Employment Challenges Despite the remarkable reduction in poverty, inequality remains a pressing issue in India: Wage inequality is high,

Pakistan Shuts Airspace, Snaps Trade Relations with India Syllabus: GS2/International Relations; GS3/Security The recent terror attack in Pahalgam has sharply intensified tensions between India and Pakistan, prompting both nations to take a series of strong retaliatory measures.     Key Measures Taken By India: Suspension of the Indus Waters Treaty Closure of the Attari-Wagah Border Cancellation of the SAARC Visa Exemption Scheme (SVES Visas) Expulsion of Pakistani Military Advisors Reduction in Diplomatic Personnel   By Pakistan: Closure of Airspace for Indian aircraft Suspension of Bilateral Trade Reduction in India’s High Commission staff Suspension of the Simla Agreement and all bilateral treaties Visa restrictions, with exceptions for Sikh pilgrims traveling to the Kartarpur Corridor Characterization of India’s Indus Treaty suspension as an ‘act of war’   Pakistan’s Airspace Closure: Implications Understanding Airspace Rights Countries hold sovereignty over their airspace, as per domestic aviation laws and international agreements. In India, the DGCA (Directorate General of Civil Aviation) governs airspace restrictions. Airspace closures are officially communicated through NOTAMs (Notice to Airmen).   International Framework Governed by the Chicago Convention, 1944 under the ICAO (International Civil Aviation Organization). Article 1 affirms a nation’s full control over its airspace. Impact of Airspace Ban Flight rerouting to Europe, North America, and the Middle East via longer paths is increasing fuel usage and costs. International airfares may rise by 8–12%, burdening passengers. Reflects the 2019 closure post-Balakot airstrikes, which cost Indian airlines over ₹700 crore.   Simla Agreement (1972) Overview A bilateral treaty signed on July 2, 1972, by Indian PM Indira Gandhi and Pakistani President Zulfikar Ali Bhutto after the 1971 India-Pakistan war, which followed India’s intervention in East Pakistan’s liberation movement.   Key Provisions All disputes, including Kashmir, to be resolved bilaterally, without third-party mediation. Mutual respect for each other’s territorial integrity and political independence. The 1971 ceasefire line in Jammu and Kashmir was converted into the Line of Control (LoC), with both sides agreeing not to alter it unilaterally. Restoration of diplomatic, trade, and cultural ties, including communication and travel. India released 93,000 Pakistani POWs, one of the largest wartime releases ever. India also returned over 13,000 km² of captured territory, except for strategic areas like the Chorbat Valley. With reference to the Simla Agreement of 1972, consider the following statements: It was signed between India and Pakistan after the Kargil War. The agreement mandated third-party mediation in resolving the Kashmir dispute. It led to the conversion of the ceasefire line into the Line of Control (LoC). India retained all territories it had captured during the 1971 war.     Which of the above statements is/are correct? A. 1 and 2 onlyB. 3 onlyC. 1, 3, and 4D. 2 and 4 only   Answer: B. 3 only Explanation: Statement 1 is incorrect: The Simla Agreement was signed after the 1971 war, not the Kargil War (1999). Statement 2 is incorrect: The agreement explicitly rejected third-party involvement, stressing bilateral resolution of disputes. Statement 3 is correct: The 1971 ceasefire line was renamed as the Line of Control (LoC). Statement 4 is incorrect: India returned over 13,000 km² of captured territory but retained only strategic parts like the Chorbat Valley. Combating Antimicrobial Resistance (AMR) in India Syllabus :GS 2/Health    In News: Health experts have raised serious concerns over the overuse of the powerful antibiotic ceftazidime-avibactam, warning that its misuse is leading to reduced therapeutic efficacy and accelerating antimicrobial resistance (AMR). The Drugs Controller General of India (DCGI) has been urged to implement stringent regulations to curb its inappropriate usage.   Understanding Antimicrobial Resistance (AMR) Antimicrobials — including antibiotics, antivirals, antifungals, and antiparasitics — are critical for treating infections in humans, animals, and plants.AMR occurs when microorganisms evolve to withstand these drugs, making infections harder to treat, increasing the risk of disease transmission, severe illness, disability, and mortality. Though AMR is a natural evolutionary process, it is greatly accelerated by: Overuse and misuse of antimicrobials in human and veterinary medicine Indiscriminate application in agriculture and aquaculture Poor sanitation and infection control Socio-economic challenges such as poverty and lack of access to clean water.   India’s AMR Burden and Challenges: India bears one of the highest burdens of bacterial infections globally. AMR contributes to prolonged hospitalizations, higher treatment costs, intensive care admissions, and increased mortality rates.   Drivers of AMR in India include: Inadequate regulatory oversight of antibiotic prescriptions High prevalence of over-the-counter sales without prescription Unregulated antibiotic use in livestock and poultry Limited awareness among healthcare professionals and the public   Steps Taken by India India is responding to the AMR crisis through multi-sectoral coordination and scientific advancements:   Genomic Surveillance & Institutional Collaboration: The Indian Council of Medical Research (ICMR), the National Centre for Disease Control (NCDC), and the Indian Council of Agricultural Research (ICAR) are leading efforts in monitoring resistance patterns and promoting rational antibiotic use.   New Antibiotic Discoveries: Recent breakthroughs such as cefepime-enmetazobactam, cefepime-zidebactam, nafithromycin, and levodifloxacin provide new weapons against multi-drug resistant pathogens, helping reduce dependence on last-resort antibiotics like carbapenems and colistin.   Public Awareness Campaigns: The Red Line Campaign marks all prescription-only antibiotics with a red line to caution against self-medication and overuse.   Antibiotic Stewardship Programs (ASPs): ICMR promotes ASPs in hospitals to guide evidence-based prescription practices and restrict unnecessary antibiotic use.   Way Forward: India possesses a robust biotechnology ecosystem, a high burden of infectious diseases, and affordable pharmaceutical manufacturing capacity. These strengths position it to lead the global fight against AMR, particularly for low- and middle-income countries. To effectively combat AMR, India must: Strengthen policy frameworks and enforcement against antibiotic misuse. Promote innovation in diagnostics, drug discovery, and surveillance. Expand awareness campaigns targeting healthcare professionals and the public. Regulate and optimize antibiotic use in animal husbandry and agriculture. Improve infrastructure, especially sanitation and infection control systems.   Conclusion: Tackling AMR requires a holistic, One Health approach, integrating human, animal, and environmental health. With the right governance, innovation, and societal participation, India can emerge as a global exemplar in combating antimicrobial resistance. With reference to Antimicrobial

Pahalgam Terror Attack and Suspension of the Indus Waters Treaty Syllabus:IR The Cabinet Committee on Security, chaired by PM Narendra Modi, has approved a 5-point action plan in response to a terrorist attack in Baisaran Valley (Pahalgam), Jammu and Kashmir, which claimed the lives of 26 civilians. The Resistance Front (TRF), a proxy group of the Pakistan-based Lashkar-e-Taiba (LeT), claimed responsibility. TRF emerged in 2020 following the elimination of LeT’s leadership in 2018 and the revocation of Article 370 in 2019. It was designated a terrorist organization under the Unlawful Activities (Prevention) Act, 1967 in 2023.     India’s 5-Point Action Plan After the Pahalgam Terror Attack Suspension of the Indus Waters Treaty (IWT):India has suspended the 1960 treaty, leveraging water diplomacy to pressure Pakistan to end cross-border terrorism. Closure of the Attari-Wagah Border:The Integrated Check Post at Attari, Punjab has been shut, halting all movement of people and goods. Only those who crossed over legally can return by May 1, 2025. Revocation of SAARC Visa Exemption for Pakistan:India has cancelled SAARC Visa Exemption Scheme (SVES) for Pakistani nationals. All existing visas under this scheme are now void. Expulsion of Pakistani Military Advisors:Pakistan’s Defence, Naval, and Air Advisors in India have been declared persona non grata. India will also recall its military advisors from Islamabad. Diplomatic Downgrade:India will reduce its diplomatic staff in Islamabad from 55 to 30 by May 1, 2025, effectively freezing bilateral dialogue.   Geopolitical Factors Behind the Attack India’s Kashmir Policy: Pakistan perceives the revocation of Article 370 and Kashmir’s integration into India as a threat to its claim over Pakistan-occupied Kashmir (PoK).   International Isolation of Pakistan: Diminished support from traditional allies (U.S., Gulf countries, even China). Post-2021 U.S. withdrawal from Afghanistan reduced Pakistan’s strategic importance. Economic Instability: Severe inflation, institutional weaknesses, and rising Baloch insurgency. Declining investor confidence and worsening GDP outlook.   Global Messaging: The attack coincided with PM Modi’s visit to Saudi Arabia and the U.S. Vice President’s trip to India—suggesting Pakistan’s attempt to reassert regional influence.   The Indus Waters Treaty (IWT) – Background and Significance Signed in 1960, mediated by the World Bank after 9 years of negotiation.   Water Allocation: Eastern Rivers (Ravi, Beas, Sutlej) – India Western Rivers (Indus, Jhelum, Chenab) – Pakistan Set up a Permanent Indus Commission and a multi-level dispute resolution mechanism.   India’s Recent Actions: 2023 & 2024: Issued notices to modify the IWT due to disputes over projects like Kishanganga and Ratle. Suspension Justified Under: Article 62 of the Vienna Convention, allowing treaty withdrawal due to fundamental changes in circumstances (i.e., cross-border terrorism).   Implications of IWT Suspension For India: Gains freedom in river management and can: Conduct reservoir flushing outside the monsoon period. Fast-track hydroelectric projects on western rivers. Deny project inspections to Pakistan. Note: Suspension won’t immediately affect Pakistan’s water supply due to India’s current infrastructure limits. For Pakistan: Major water security risks—80% of agriculture depends on Indus waters. Threats to: Food and water supply Power generation Economic stability (Indus system fuels 25% of Pakistan’s GDP) May seek World Bank arbitration, and approach allies like China—but economic constraints limit retaliation.   India’s Key Dams on the Indus System Kishanganga (Jhelum): Operational since 2018; diverts water from a key Mangla Dam tributary. Ratle (Chenab): Under construction; could reduce flow to Pakistan’s Punjab. Shahpurkandi (Ravi): Diverts Ravi water to Indian channels. Ujh (Ravi): Planned dam to further reduce Pakistan’s water access.   India’s Long-Term Strategic Roadmap Strengthen Deterrence Enhance border security with high-tech surveillance and smart fencing. Maintain a modern, responsive military presence. Leverage Global Forums Highlight Pakistan’s support for terrorism at the UN Security Council. Use Article 51 of the UN Charter to advocate for collective action. Push for FATF blacklisting of Pakistan for terror financing. Internal Security & Social Cohesion Deploy counter-radicalization efforts in border regions. Promote unity through public awareness on pluralism and peace. With reference to the Indus Waters Treaty (IWT), consider the following statements: The IWT allocates the three eastern rivers to Pakistan and the three western rivers to India. The Treaty allows India unrestricted use of western rivers for hydroelectricity, subject to specific design constraints. Article XII of the Treaty provides for its suspension in case of material breach by either party. India’s suspension of the IWT in 2025 is the first such instance since the treaty’s inception. Which of the statements given above is/are correct? A. 1 and 2 onlyB. 2 and 4 onlyC. 4 onlyD. 2, 3 and 4 only Answer: B. 2 and 4 only Explanation: Statement 1 is incorrect: The eastern rivers (Ravi, Beas, Sutlej) are allocated to India, and the western rivers (Indus, Jhelum, Chenab) to Pakistan. Statement 2 is correct: India is allowed limited non-consumptive use of western rivers, such as for hydroelectric projects, but subject to design limitations. Statement 3 is incorrect: There is no provision in Article XII for suspension due to material breach. However, under Article XII(3), the treaty can be modified through mutual agreement. India’s recent action is being justified under Article 62 of the Vienna Convention, not under IWT itself. Statement 4 is correct: This is indeed the first time since 1960 that India has suspended the treaty. SAARC Visa Exemption Scheme Syllabus:IR Following the terror attack in Pahalgam, Jammu & Kashmir, the Cabinet Committee on Security (CCS) has revoked the SAARC Visa Exemption Scheme (SVES) for Pakistani nationals. This move is a firm diplomatic measure in response to Pakistan’s continued sponsorship of cross-border terrorism.     What is the SAARC Visa Exemption Scheme (SVES)? Launched: 1992, based on a decision from the 4th SAARC Summit (1988, Islamabad). Objective: To promote regional integration and people-to-people connectivity among SAARC nations. Mechanism: Eligible individuals are issued a Special Travel Document (Visa Sticker) that permits visa-free travel within member states.   Coverage Applicable to 24 categories, including: Heads of State Parliamentarians Judges Senior officials Businesspersons Journalists Sportspersons, etc. Visa Stickers are typically valid for one year, issued by the home country, and subject to immigration clearance. India-Specific Provisions

Arsenic Pollution Syllabus: Environment   Context: A recent study published in The Lancet Planetary Health warns that climate change may increase arsenic levels in rice, posing serious health risks in Asia by 2050.   What is Arsenic (As)? A naturally occurring trace element, commonly found in combination with sulfur and metals in minerals Highly toxic in its inorganic form     Health Impacts of Arsenic Exposure: Long-term exposure may lead to: Cancer, skin lesions, cardiovascular disease, and diabetes Early-life exposure (in-utero or childhood): Impaired cognitive development Increased mortality in young adults Blackfoot Disease (Taiwan): A severe vascular condition linked to arsenic, leading to gangrene   Permissible Limits: WHO Guideline:01 mg/l (10 μg/l) India (in absence of alternative):05 mg/l (50 μg/l)   Arsenic Contamination in India: First identified in West Bengal (1980) Widespread contamination in the Ganga–Brahmaputra alluvial plains Affects millions of people through contaminated groundwater   Government Initiatives: National Rural Drinking Water Programme (NRDWP): Focuses on providing safe drinking water Targets removal of contaminants like arsenic and fluoride   ‘AMRIT’ Technology by IIT-Madras: Innovative method to remove arsenic and metal ions from water Supports affordable, scalable water purification Consider the following statements about arsenic contamination in India: The highest concentrations of arsenic are found in hard rock aquifers of peninsular India. The permissible limit of arsenic in drinking water is stricter in India than the WHO standard. Arsenic contamination is predominantly an issue in alluvial plains. Which of the above statements is/are correct? A. 1 and 2 onlyB. 3 onlyC. 1 and 3 onlyD. 2 and 3 only Answer: B. 3 only Explanation: Statement 1 is incorrect: The highest concentrations are found in alluvial aquifers (Ganga–Brahmaputra plains), not hard rock aquifers. Statement 2 is incorrect: India’s permissible limit (0.05 mg/l) is more lenient than the WHO standard (0.01 mg/l). Statement 3 is correct: Arsenic contamination is a major issue in the alluvial plains due to geological and hydrological factors. Gold Prices Cross Rs 1 lakh-mark For First Time Syllabus: GS3/Economy Context: Gold prices in India have surged past ₹1 lakh per 10 grams, marking an all-time high and drawing attention to the underlying global and domestic economic factors.   Key Factors Influencing Gold Prices: Supply and Demand Dynamics: Higher mining output can reduce prices. Increased demand (for investment, jewelry, or industrial use) pushes prices upward.   Inflation: Gold acts as a hedge against inflation. Rising inflation increases demand for gold, driving prices higher.   Interest Rates: Lower interest rates make gold more attractive as it offers no yield but becomes more competitive. Higher rates lead to lower gold prices due to increased opportunity cost.   Geopolitical Instability: Political tensions, wars, or global crises boost demand for gold as a safe haven asset.   Currency Fluctuations: Gold is priced in S. dollars. A weaker dollar makes gold cheaper for other currencies, increasing global demand.   Central Bank Policies: Central banks buying or selling gold significantly influence global prices. Gold is a key component of central banks’ foreign exchange reserves.   Global Economic Conditions: During economic downturns or recessions, investors turn to gold for stability, raising its value.   Key Global Facts About Gold: Top Gold Producers: China (largest) Russia Australia   Top Gold Consumers: China India   Largest Gold Reserves (by country): United States – ~8,133.5 metric tons Germany Italy Consider the following statements regarding the relationship between inflation and gold prices: Gold is an inflation-sensitive commodity due to its industrial utility. In inflationary periods, real interest rates usually rise, making gold more attractive. Gold’s value often rises as it acts as a store of value when currency depreciates. Which of the above statements is/are correct? A. 3 onlyB. 1 and 2 onlyC. 2 and 3 onlyD. 1, 2, and 3 Answer: A. 3 only Explanation: Statement 1 is incorrect: Gold’s price sensitivity in inflation isn’t due to industrial use but due to its monetary role as a hedge. Statement 2 is incorrect: Inflation typically lowers real interest rates, which makes non-yielding assets like gold more attractive. Statement 3 is correct: Gold maintains purchasing power when currency loses value. Green Way to Recycle Toxic Perovskite Solar Cells Syllabus: GS3/ Science and Technology   A recent study published in Nature highlights a novel water-based method for recycling Perovskite Solar Cells (PSCs), aiming to reduce environmental risks associated with traditional recycling techniques.   What are Perovskite Solar Cells (PSCs)?
