  • Seasonal Impact of Monsoons on Wind Power

    Why in the News?

    The onset of cool, moisture-laden monsoon winds offers not just relief but also a significant opportunity for wind energy generation.

    About the Indian Monsoon:

    • Origin: The word “monsoon” comes from Arabic ‘mausin’ or Malayan ‘monsin,’ meaning “season”.
    • Seasonal Wind Shift: Monsoons are seasonal winds that reverse direction with changing seasons.
    • Types:
      1. Southwest Monsoon: Blows from sea to land, bringing rainfall across most of India.
      2. Northeast Monsoon: Blows from land to sea, bringing rain mainly to southeast India.
    • Role of Tibet: The Tibetan Plateau heats up in summer, creating low pressure that draws in moist winds.
    • Ocean Influence: A high-pressure system in the southern Indian Ocean helps drive the southwest monsoon.
    • Atmospheric Factors: Influencers include the Subtropical Jet Stream, Tropical Easterly Jet, and ITCZ.
    • Other Drivers: The Somali Jet, Somali Current, Indian Ocean Dipole, and Walker Cell also affect monsoon behaviour.

    How does monsoon impact wind variability?

    • Changing Wind Speeds: Monsoon wind speeds vary in strength and direction over time and place.
    • Energy Planning: Wind behaviour prediction is crucial for renewable power management, especially wind energy.
    • Agricultural Demand: Kharif crops planted in June depend on monsoon, raising seasonal energy demand.
    • Wind Energy Output: In areas like the Western Ghats, 70% of wind energy is generated June–September.
    • Forecasting Tools: Numerical Weather Prediction (NWP) models provide high-resolution wind forecasts.
    • AI Models: Tools like Google’s MetNet3 use satellite and radar data to predict wind in remote areas.

    India’s Wind Energy: Capacity, Growth & Challenges

    • India became the 3rd largest wind and solar producer in 2024, after China and the US.
    • Installed wind capacity: 50 GW as of March 31, 2025.
    • In 2024, wind and solar contributed 10% of electricity—solar 7%, wind 3%; hydro added 8%, totalling 22% from clean sources.
    • Solar capacity grew by 24 GW in 2024, doubling 2023’s figure; wind grew by 3.4 GW.
    • Leading wind additions: Gujarat (1,250 MW), Karnataka (1,135 MW), Tamil Nadu (980 MW).
    • Top wind states: Tamil Nadu, Gujarat, and Maharashtra; targets: 140 GW wind and 500 GW non-fossil capacity by 2030.
    • Land Use & Capacity Utilization Factor (CUF): Wind farms occupy just 2% of land, allowing agriculture on the rest; CUF ranges between 16%–19%, with peak generation during monsoon months.

     

    [UPSC 2014] The seasonal reversal of winds is the typical characteristic of:

    About the Kingdom of Sikkim

    • Foundation: The Kingdom of Sikkim was established in 1642, when three Tibetan lamas crowned Phuntsong Namgyal as the first Chogyal (monarch).
    • Namgyal dynasty: It ruled Sikkim for 333 years, maintaining a Buddhist monarchy until 1975.
    • Treaty of Tumlong (1861): It made Sikkim a British protectorate, where the Chogyals retained internal authority while the British handled external affairs.
    • Other key treaties shaping Sikkim’s status: These included the Treaty of Titaliya (1817), Calcutta Convention (1890), and Lhasa Convention (1904), which defined borders and reaffirmed British influence.

    How did Sikkim join India?

    • Post-1947 Status: After India’s independence, Sikkim did not join India like other princely states, due to its unique British treaty status.
    • Nehru’s Approach: While Sardar Patel and B.N. Rau wanted Sikkim to accede, Jawaharlal Nehru opted for a Standstill Agreement to preserve the status quo.
    • Indo-Sikkim Treaty of 1950: This treaty made Sikkim an Indian protectorate, with India managing defence, foreign affairs, and communications.
    • Role of Sikkim National Congress: Led by Kazi Dorji, the SNC became the key pro-democracy and pro-merger party.
    • 1973 Agreement: After widespread protests, a tripartite agreement was signed between the Chogyal, the Government of India, and the Sikkimese parties.
    • Democratic Transition: In 1974, elections were held, and a new constitution reduced the monarch’s powers.
    • Referendum of 1975: In April 1975, over 97% of voters supported abolishing the monarchy and merging with India.
    • Merger with India: In May 1975, the 36th Constitutional Amendment was passed, and Sikkim became the 22nd state of India. It added Article 371F to provide special provisions for the state of Sikkim.

  • [10th May 2025] The Hindu Op-ed: Sprouting sustainable, nutrition-sensitive food systems 

    PYQ Relevance:

    [UPSC 2024] Explain the role of millets for ensuring health and nutritional security in India.

    Linkage: Nutrition-sensitive agriculture and promoting the cultivation of climate-resilient, biofortified crops, and enhancing crop diversity. Millets are a prime example of such crops that contribute to health and nutritional security, making this question highly relevant to the article’s proposed solutions for improving dietary quality and nutritional outcomes.

     

    Mentor’s Comment:  The global food system is under pressure due to limited resources and climate change, while still needing to make food accessible and affordable. Even though India is a top producer of milk, fruits, vegetables, grains, and livestock, it still faces serious nutrition problems. These include both undernutrition and rising obesity, along with a lack of essential vitamins and minerals. Such issues put India’s future workforce and economic strength at risk. With a low rank of 105 out of 127 countries in the Global Hunger Index 2024, India’s food insecurity needs immediate attention.

    Today’s editorial discusses the problem of malnutrition in India. This topic is useful for GS Paper 2 (which covers the role of the welfare state and government schemes to fight malnutrition) and GS Paper 3 (which looks at India’s food system).

    Let’s learn!

    Why in the News?

    India’s fight against nutrition problems should lead to a change where nutrition is included as a key part of farming and economic planning.

    What is the situation of India in malnutrition? 

    • Alarming Dual Burden of Malnutrition: NFHS-5 data highlights India’s pressing nutrition crisis — with high rates of stunting (35.5%), underweight (32.1%), wasting (19.3%) among children, and rising obesity in adults (24% women, 22.9% men), reflecting a dual burden of undernutrition and overnutrition that demands urgent policy attention.
    • Hidden Hunger and Women’s Health: The prevalence of anaemia in 57% of women of reproductive age signals widespread micronutrient deficiencies, indicating that calorie sufficiency alone is not enough — interventions must ensure access to diverse, nutrient-rich foods.

    What are the key causes of malnutrition in India despite being a major food producer?

    • Inequitable Access: Despite high food production, millions cannot afford or access diverse and nutritious diets. Eg: As per FAO (2022), 55.6% of Indians are unable to afford a healthy diet, highlighting widespread economic and geographic disparities.
    • Hidden Hunger (Micronutrient Deficiency): Diets often lack essential vitamins and minerals, affecting physical and cognitive development. Eg: 57% of Indian women of reproductive age are anaemic, despite surplus grain availability.
    • Food System Inefficiencies: Overreliance on staples, poor storage, and inadequate supply chains limit access to nutrient-rich food. Eg: Focus on rice and wheat in PDS sidelines coarse grains and pulses, leading to reduced dietary diversity.
    • Double Burden of Malnutrition: India faces both undernutrition in children and growing rates of overweight/obesity in adults. Eg: 35.5% of children under 5 are stunted, while 24% of women are overweight, showing nutrition imbalance.
    • Climate Vulnerability: Extreme weather events and resource stress reduce crop yield and diversity, harming food security. Eg: Erratic monsoons and heatwaves reduce the productivity of small-scale farmers, limiting supply of fresh produce.

    How can nutrition-sensitive agriculture contribute to addressing India’s food security issues?

    • Crop Diversification: Promotes the cultivation of a variety of nutrient-rich crops to improve dietary diversity. Eg: Encouraging farmers to grow millets, pulses, and vegetables alongside cereals enhances household nutrition and resilience.
    • Biofortification: Increases the nutritional content of staple crops to combat micronutrient deficiencies. Eg: Use of iron-rich pearl millet and zinc-enhanced wheat has shown success in improving child and maternal health.
    • Climate-Resilient Crops: Supports food security under changing climate conditions by using crops that can withstand droughts and floods. Eg: Drought-tolerant varieties of sorghum and finger millet help ensure food supply in arid and semi-arid regions.
    • Improved Post-Harvest Management: Reduces food loss and maintains nutrient quality through better storage and transportation. Eg: Solar dryers and community storage units help preserve perishable crops like fruits and vegetables in rural areas.
    • Farmer-Nutrition Linkages: Connects local farmers with schools and public schemes to supply nutritious food, boosting rural incomes and food access. Eg: The Nutri-Garden model in schools sources biofortified grains and vegetables from nearby farms, improving child nutrition.

    Who should play a key role in transforming India’s food systems for better nutrition and sustainability?

    • Government: Must align agricultural, health, and economic policies with nutrition and sustainability goals. Eg: The government can enhance the Public Distribution System (PDS) by including nutrient-rich millets and local vegetables.
    • Private Sector: Should innovate and invest in nutrition-focused food products, fortification, and sustainable practices. Eg: Food companies using clear nutrition labels and QR codes to promote awareness and adopting plant-based alternatives.
    • Community and Civil Society: Essential in driving grassroots efforts, promoting awareness, and implementing local nutrition initiatives. Eg: Nutrition-Sensitive Community Planning (NSCP) empowers villages to improve diet through local food, water, and health solutions.

    Where can community-led nutrition interventions like the Nutrition-Sensitive Community Planning (NSCP) model be most effective in India?

    • Rural Areas with Poor Nutrition Indicators: Effective where malnutrition, stunting, and anaemia are high among children and women. Eg: In parts of Bihar and Madhya Pradesh, NSCP can address undernutrition by linking local farming to nutritious diets.
    • Tribal and Remote Regions: Helps revive indigenous food systems and addresses deep-rooted nutrition gaps. Eg: In Odisha’s tribal districts, NSCP can promote traditional millets and forest foods as part of daily meals.
    • Climate-Vulnerable Zones: Strengthens resilience through climate-adaptive farming and diversified diets. Eg: In Bundelkhand (UP-MP), NSCP can integrate drought-tolerant crops and water-saving practices.
    • Regions with High Migration Rates: Targets nutritional needs of women and children left behind in migrant families. Eg: In eastern Uttar Pradesh, NSCP can ensure food security through community gardens and village nutrition hubs.
    • Urban Slums and Peri-Urban Settlements: Addresses the dual burden of undernutrition and rising obesity in low-income households. Eg: In Delhi’s informal settlements, NSCP can promote rooftop kitchen gardens and access to local fresh food markets.

    What are the steps taken by the Indian government? 

    • Universal Fortified Rice & Diversified Safety Nets: India has rolled out fortified rice (iron, folic acid + B12) across every food-security scheme—PDS, PM-GKAY, ICDS, Mid-Day Meal/PM POSHAN—to cut anaemia and hidden hunger.  
    • Mission Poshan 2.0 (Saksham Anganwadi + Nutrition Mission): Combines ICDS, Poshan Abhiyaan and allied schemes into one platform that uses real-time growth monitoring, fortified take-home rations and community “Poshan Maah” drives to reduce stunting, wasting and anaemia. Eg: Mission Poshan 2.0 uses a three-pronged strategy—convergence, technology and social behaviour change—through 1.4 million Anganwadis.
    • Millet Promotion & Climate-Resilient Farming: The government declared 2023 the International Year of Millets, rebranded them as “Nutri-Cereals,” and launched programmes to expand climate-smart, nutrient-dense crops.

    Way forward: 

    • Enhance Multi-Stakeholder Collaboration: Strengthen coordination between government, private sector, and civil society to scale up nutrition-sensitive initiatives and ensure equitable access to nutritious food for all segments of society.
    • Promote Sustainable and Climate-Resilient Agricultural Practices: Encourage the adoption of climate-smart farming techniques and crop diversification to ensure food security in the face of climate challenges while improving nutritional outcomes.

    PYQ Relevance:

    [UPSC 2021] “There arose a serious challenge to the Democratic State System between the two World Wars.” Evaluate the statement.

    Linkage: The period “between the two World Wars”, providing a broader historical context related to World War II which is the focus of Article. It prompts discussion on the challenges to democratic systems during this era.

     

    Mentor’s Comment:  Eighty years ago, on May 8, 1945, the Second World War officially ended in Europe when Nazi Germany surrendered to the Allied forces in Reims and Berlin. This day is celebrated as Victory in Europe (VE) Day, but in India, it often goes unnoticed, as the years of the war (1939-1945) are mainly remembered as the final phase of the struggle for independence. It is important to remember that Indians never ignored their duties to the world, whether in war or peace, as shown by the lives of two lesser-known Indians.

    Today’s editorial examines the contributions of lesser-known Indian heroes like Kolachala Sitaramaiah and Idris Hasan Latif during World War II. This content will be useful for GS Paper I (World History) and GS Paper II (International Relations).

    Let’s learn!

    Why in the News?

    On May 9th, Victory in Europe Day is also a time to honor the brilliance of scientists like Kolachala Sitaramaiah and the courage of soldiers like Idris Hasan Latif during World War II.

    Who was Kolachala Sitaramaiah?

    • Kolachala Sitaramaiah (July 15, 1899 – September 29, 1977) was a renowned chemist and is often referred to as the “Father of Chemotology,” the field dedicated to the study of lubricants and combustible materials in technology.
    • Born in Uyyuru, Andhra Pradesh, he pursued advanced studies abroad, where he made substantial contributions to the understanding of lubricants, particularly their role in machinery and the development of motor oils.

    What contributions did he make during the Second World War?

    • Fuel Innovation for Soviet Tanks: He developed kerosene-based fuels and specialized lubricants that significantly enhanced the performance and maneuverability of Soviet tanks in sub-zero battlefield conditions. Eg: These innovations were critical during the Battle of Kursk (1943), where Soviet T-34 tanks outperformed Nazi Panzer and Tiger tanks.
    • Scientific Expertise Redirected to War Effort: Although he volunteered for frontline combat, Soviet authorities recognized his intellectual value and redirected him to research, stating his brain was a weapon, not a target. Eg: His work helped overcome early mechanical failures in Soviet tanks, crucial to halting the Nazi ground offensive.
    • Foundation for Future Scientific Fields: His wartime research laid the groundwork for chemmotology (tribochemistry) — the study of chemical changes from mechanical energy — and later contributed to plasma research important for nuclear fusion. Eg: His observations of incendiary weapons inspired deeper scientific inquiry into the fourth state of matter — plasma.

    What were the challenges faced by Indian pilots like Idris Latif during their missions in the Second World War?

    • Inferior Aircraft and Equipment: Indian pilots were initially assigned outdated biplanes, putting them at a disadvantage in combat situations. Eg: Idris Latif flew patrols along the North West Frontier in old aircraft while British pilots used advanced models.
    • Dangerous Combat Environments: They flew missions in extremely hostile conditions, including thick jungles, poor visibility, and constant threat of enemy fire. Eg: In Burma, Idris flew the Hawker Hurricane against Japanese Zero fighters, often from muddy, short landing strips.
    • Health Hazards and Illness: Pilots endured unhygienic, disease-prone environments, which led to severe illnesses. Eg: Idris Latif fell gravely ill in the humid, mosquito-infested jungles of Burma but refused to abandon his squadron.
    • Lack of Recognition and Discrimination: Despite their service, Indian pilots often faced racial bias and were under-acknowledged by the colonial British authorities. Eg: Idris and others had to prove themselves repeatedly before being entrusted with frontline roles in Europe.
    • Emotional and Moral Dilemmas: Indian soldiers and pilots had to reconcile serving a colonial power while also yearning for India’s independence. Eg: Despite these conflicts, Idris remained committed to fighting fascism and later chose to stay in independent India post-Partition.

    When did Idris Hasan Latif become the Chief of the Indian Air Force? 

    • Appointment as Air Chief Marshal: Idris Hasan Latif became the 10th Chief of the Indian Air Force in 1978, marking a significant moment in IAF history. He was the first Muslim to hold the top position in the Indian Air Force.
    • Recognized for Wartime Service and Leadership: His distinguished service during the Second World War and later roles earned him this high command. His performance in combat and leadership roles post-independence showcased his capabilities.

    How did he contribute to strengthening India-France defence relations?

    • Role as India’s Ambassador to France (1985–1988): After retiring as Air Chief Marshal, he was appointed Ambassador to France, a key position for defence diplomacy. Eg: His presence in Paris helped facilitate high-level strategic discussions on defence cooperation.
    • Leveraging Wartime Bonds: His personal connection to World War II and Normandy fostered shared respect and trust with French counterparts. Eg: He visited Normandy during his tenure, recalling his war contributions, which resonated deeply with French officials.
    • Military-to-Military Cooperation: He actively promoted exchanges between Indian and French armed forces and encouraged joint training initiatives.
    • Laying Groundwork for Future Defence Deals: His tenure helped build the foundation of trust that later enabled critical defence procurements. Eg: The Rafale fighter jet deal, though signed much later, benefited from the diplomatic groundwork laid during his ambassadorship.
    • Promoting Indigenous Capability through Collaboration: He supported technology transfers and joint development possibilities with France. Eg: His diplomatic efforts aligned with India’s interest in acquiring not just equipment but also technical know-how.

    What is the evolution of the Indian Air Force (IAF)?

    • Formation and Early Years (1932–1947): The IAF was established in 1932 as an auxiliary force under British rule, participating in World War II with limited autonomy. Eg: Indian pilots flew biplanes in the Burma campaign during WWII.
    • Post-Independence Expansion (1947–1960s): After 1947, the IAF was reorganized as an independent force, expanding its fleet and training infrastructure.  Eg: IAF played a crucial role in the 1947–48 Kashmir conflict using Dakotas to airlift troops.
    • Modernisation after Wars (1970s–1990s): Following wars with Pakistan and China, India focused on acquiring advanced aircraft and building indigenous capability. Eg: Introduction of MiG-21s, Miraj 2000 and establishment of HAL’s fighter production line.
    • Technology Integration and Strategic Reach (2000s): The IAF integrated AWACS, aerial refuellers, precision-guided munitions, and enhanced air defence systems. Eg: Induction of Sukhoi Su-30 MKI significantly improved long-range strike capability.
    • Next-Gen Air Power and Global Partnerships (2010s–Present): IAF has adopted network-centric warfare, multirole fighters, and AI-based systems, while deepening global defence ties. Eg: Procurement of Rafale jets from France and participation in multilateral exercises like Red Flag and Garuda.

    What is the role of France in the Indian Air Force? 

    • Strategic Defence Partner Since Early Years: France has been a consistent defence partner for India, supplying key aircraft and technology since the 1950s. Eg: France provided Ouragan (Toofani) jets in the 1950s, among IAF’s first jet fighters.
    • Supplier of Multirole Combat Aircraft: French aircraft have strengthened IAF’s strike capabilities through advanced multirole platforms. Eg: The Dassault Mirage 2000, inducted in 1985, played a decisive role in the Kargil War (1999).
    • Rafale Fighter Jet Deal: The acquisition of 36 Rafale jets enhanced India’s air dominance with advanced avionics, weaponry, and capabilities. Eg: Rafale jets were inducted starting in 2020 under a government-to-government deal with France.
    • Technology Transfer and Maintenance Support: France has supported India through tech transfer, joint production, and robust maintenance infrastructure. Eg: Hindustan Aeronautics Limited (HAL) maintained and upgraded Mirage 2000s with French collaboration.
    • Joint Exercises and Defence Diplomacy: India and France regularly conduct joint air exercises that enhance IAF’s tactical exposure and interoperability. Eg: The Garuda series of exercises improve coordination between French and Indian air forces.

    Way forward: 

    • Deepen Strategic Collaboration in Emerging Technologies: India and France should jointly invest in cutting-edge aerospace technologies such as AI-based combat systems, stealth UAVs, and hypersonic platforms to future-proof IAF capabilities.
    • Expand Joint Training and Indo-French Defence Industrial Base: Encourage co-development and co-production of next-generation aircraft and defence systems under Make in India, while scaling up joint military exercises like Garuda for enhanced operational synergy.
