Current Affairs Quiz - May 2025

Notes:
The American Association of Petroleum Geologists and the United States Geological Survey (USGS) have recently launched formal hydrogen exploration initiatives. Hydrogen is seen as the fuel of the future due to its ability to help decarbonize the global economy and reduce greenhouse gas emissions. Natural hydrogen, or white hydrogen, is hydrogen that naturally occurs in the Earth’s crust, unlike industrially produced hydrogen. It forms through geological processes such as serpentinisation, where water reacts with iron-rich rocks, radiolysis, the breakdown of water by radioactive rocks, and the decomposition of organic matter in deep geological formations.

Notes:
Operation Kagar has successfully encircled the last remaining Naxal strongholds in the Chhattisgarh-Telangana border regions. Operation Kagar was launched by the Ministry of Home Affairs to eliminate Maoist insurgents and dismantle the political ideology of Maoism. The operation combines military action, surveillance technology, and development outreach to combat Left-Wing Extremism (LWE). The campaign has reduced Naxal-affected districts from 106 in 2015 to just 6 in 2025. In 2024, 287 Naxals were neutralized, with over 150 already in 2025.

Notes:
Global defence spending is rising fast due to uncertainty and rapid technology growth. As per Stockholm International Peace Research Institute (SIPRI), military expenditure reached $2.718 trillion in 2024, a 9.4% rise from 2023. China has the largest active military force with 2,035,000 personnel in 2025, according to Global Firepower. India ranks second with about 1,455,550 active personnel, showing strong defence strength and rising South Asian influence. The United States of America stands third with 1,328,000 troops, slightly reduced due to more focus on tech-based defence. Russia and Ukraine boosted troop numbers since 2022 due to ongoing conflict between them.

Notes:
Every year on May 3, World Press Freedom Day is celebrated to highlight the vital role of the media, known as the fourth pillar of democracy. The day spreads awareness about the struggles faced by journalists and supports the free flow of information. It honours media professionals who have risked or lost their lives in search of truth. This year’s theme is ‘Reporting In The Brave New World – The Impact Of Artificial Intelligence On Press Freedom And The Media.’ The day was established by the United Nations General Assembly (UNGA) in 1993 after a 1991 recommendation by UNESCO.

Notes:
The International Monetary Fund (IMF) recently projected that global public debt may surpass the COVID-19 pandemic level of 98.9% of Gross Domestic Product (GDP) recorded in 2020. Sudan now has the highest debt-to-GDP ratio in the world at 252%, due to long-term conflict and economic struggles. Among developed countries, Japan ranks second with a debt-to-GDP ratio of 234.9%, mainly due to fiscal deficits and an ageing population. The United States ranks eighth with a ratio of 123%, while France and Canada follow with 116.3% and slightly lower respectively. China ranks 21st globally with a public debt ratio of 96%, which is lower than many advanced economies. India stands at 31st with a debt-to-GDP ratio of 80%, and the central government aims to reduce it to 50±1% by March 31, 2031.

Notes:
The National Dam Safety Authority (NDSA) has reported major damage to the Kaleshwaram Lift Irrigation Project (KLIP) barrages after the 2023 floods. NDSA is India’s national safety regulator for large dams and was established under the National Dam Safety Act, 2021. KLIP is a multi-purpose irrigation project built on the Godavari River in Kaleshwaram, Telangana. The Godavari River, also called Dakshin Ganga, is the largest river in Peninsular India and originates from the Western Ghats in Nasik, Maharashtra. KLIP is set to become the world’s largest multi-stage lift irrigation project, using pumps to lift water to high points for irrigation.

Notes:
The Maharashtra government launched the “One State, One Registration” scheme to make property registration easy and citizen-friendly. It allows people to register property documents at any sub-registrar office in Maharashtra, regardless of where the property is located. Earlier, buyers had to register documents only at the local sub-registrar office of the property, which caused delays and overcrowding. The new policy saves time, reduces paperwork, and helps senior citizens and Non-Resident Indians (NRIs). Legal steps and documents like sale deed, Aadhaar, and PAN remain unchanged. It does not affect stamp duty or registration fees. The National Informatics Centre (NIC) is using technology like Geographic Information System (GIS), drone mapping, and blockchain for better accuracy. This move is expected to boost real estate activity and investor confidence in the state.

Notes:
Maharashtra has become the first Indian state to approve a dedicated and independent Shipbuilding, Ship Repair and Ship Recycling Policy. The goal is to make Maharashtra a leading hub for shipbuilding, ship repair, and ship recycling. The state targets an investment of ₹6,600 crore and 40,000 jobs by 2030. By 2047, the aim is to attract ₹18,000 crore in investments and create 3.3 lakh jobs. The policy supports research and development (R&D), modern technology, and skilled workforce. It aims to contribute one-third of India’s total shipbuilding output by 2030.

Notes:
The Indian Institute of Technology Bombay (IIT-Bombay) has been appointed to lead the recently launched ‘Pushpak – National Mission on Drone Technology’. The mission was started by the Ministry of Electronics and Information Technology (MeitY) with a grant-in-aid of ₹82.7 crore. It aims to boost the development of indigenous drone technology across key sectors in India. IIT-Bombay will work on hybrid drones, indigenous processors, and Unmanned Aerial Systems (UAS) for disaster response and coastal monitoring. Veermata Jijabai Technological Institute (VJTI), Mumbai, will develop secure embedded systems and improve drone cybersecurity. A drone security lab and forensic unit will also be set up to monitor flight patterns and prevent drone threats.

Notes:
Defence Research and Development Organisation (DRDO) and Indian Navy successfully carried out combat firing of the Multi-Influence Ground Mine (MIGM) with reduced explosives. MIGM is an advanced underwater naval mine developed by Naval Science and Technological Laboratory, Visakhapatnam, with support from other DRDO labs. It is designed to target stealth ships and submarines, enhancing the Indian Navy’s underwater combat strength. The mine has intelligent systems with ARM processor-based electronics that process sensor data in real time for precise defence action. Bharat Dynamics Limited and Apollo Microsystems Limited are the production partners. The system will strengthen India’s coastal defence and underwater deterrence.
