Current Affairs Quiz - May 2025

Notes:
The Vembanad Lake Rejuvenation Project, led by the Alappuzha District Administration, is inspired by the Namami Gange Programme for river conservation. A five-year plan worth ₹188.25 crore has been submitted to the Chief Minister of Kerala and may be revised based on studies by the Centre for Water Resources Development and Management (CWRDM). Vembanad Lake is the longest lake in India and the largest in Kerala, stretching about 96.5 kilometres. It spreads across Alappuzha, Kottayam, and Ernakulam districts, covering around 2,033 square kilometres. The lake is known by names like Vembanad Kayal, Punnamada Lake, and Kochi Lake in different regions. It receives water from six rivers, including Meenachil, Achankovil, Pamba, and Manimala, and drains into the Arabian Sea.

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:
The Asian Games 2026 will be held in Aichi and Nagoya, Japan, from September 19 to October 4. This will mark the third time the Asian Games is being hosted in Japan, after Tokyo in 1958 and Hiroshima in 1994. Cricket has been officially retained for the Asian Games 2026. Mixed Martial Arts (MMA) will make its debut in the 2026 edition of the continental event.

Notes:
The Prime Minister of India will officially inaugurate the Vizhinjam International Seaport in Kerala, marking a major milestone in global maritime connectivity for the state. Vizhinjam Port is located in Vizhinjam, a coastal town in Thiruvananthapuram district of Kerala. It is India’s first dedicated transshipment port and also the country’s first semi-automated port. The port is built at a cost of about ₹8,900 crore under the Public-Private Partnership (PPP) model and is operated by the Adani Group, while the Kerala government holds the majority stake. It has the deepest breakwater in India, nearly three kilometres long, with a natural draft of about 20 metres. The port features India’s first home-built, Artificial Intelligence (AI)-powered Vessel Traffic Management System, developed with Indian Institute of Technology (IIT) Madras.

Notes:
Nepal has introduced a new draft law to allow only experienced climbers, who have scaled peaks above 7,000 metres, to attempt Mount Everest. This step comes in response to rising deaths, overcrowding, and environmental damage on the world’s tallest mountain. By restricting access, Nepal hopes to improve climber safety and promote responsible tourism. The law aims to ensure that only skilled mountaineers with proven high-altitude experience undertake such risky expeditions. The move also supports environmental conservation by addressing waste buildup and uncontrolled tourist flow in the fragile Everest ecosystem. This reflects Nepal’s growing commitment to sustainable mountaineering practices.

Notes:
India has recently received a new shipment of Russian Igla-S air defence missiles amid rising tensions with Pakistan after the Pahalgam terror attack. Igla-S is a Man Portable Air Defence System (MANPADS) developed by Russia. It is a hand-held system that can be used by one person or a small crew. It is designed to shoot down low-flying aircraft, cruise missiles, and drones.

Notes:
India recently halted the flow of water through the Baglihar Dam on the Chenab River, a significant move impacting water access to Pakistan. The Baglihar Dam, also known as the Baglihar Hydroelectric Power Project, is located on the Chenab River in the Doda District of Jammu and Kashmir. It features a concrete gravity dam that is 144.5 meters high and 363 meters long, with a reservoir capacity of 475 million cubic meters. The underground powerhouse of the project measures 221 meters long, 24 meters wide, and 51 meters high.

Notes:
Lawrence Wong has been elected as Prime Minister of Singapore. He is from the People’s Action Party (PAP), which has ruled Singapore since independence. Wong is an economist and served as the Finance Minister since 2021 before becoming Prime Minister. In the 2025 general elections, under his leadership, PAP won 87 out of 97 parliamentary seats. This included 82 seats through voting and 5 uncontested. The PAP’s popular vote increased to 65.6 percent, showing strong public support.

Notes:
Scientists recently found signs of ancient wildfires, called palaeofires, from the Permian Period about 250 million years ago in the Godavari Basin. Palaeofires are wildfire events recorded in ancient rocks, helping us understand Earth’s past vegetation, climate changes, and coal formation. The study covered a long geological timescale, from the Late Silurian to the present Quaternary Period. Researchers used methods like Palynofacies analysis, Raman Spectroscopy, Rock-Eval Pyrolysis, and Fourier Transform Infrared (FTIR) Spectroscopy to study tiny fossils and charcoal. They clearly identified charcoal formed on-site (in situ) and transported charcoal (ex situ), solving a major geological debate. They also found that sea-level changes affected how fire residues were preserved—more intact during sea-level drops (regressive) and more scattered during sea-level rise (transgressive).

Notes:
The Cabinet Committee on Economic Affairs (CCEA), chaired by Prime Minister Narendra Modi, approved the revised SHAKTI scheme on May 8, 2025. SHAKTI stands for Scheme for Harnessing and Allocating Koyala Transparently in India, aimed at providing coal to thermal power plants. The revised policy simplifies the coal linkage process to help power plants meet short-term and long-term needs. It introduces two windows: coal at notified price and coal at premium over notified price. Central and state thermal power projects, including joint ventures, will get coal at notified price as per existing rules. States can allocate this coal to their own power companies or Independent Power Producers (IPPs) chosen through Tariff-Based Competitive Bidding (TBCB).
