Current Affairs Quiz - May 2025

Notes:
India recently signed agreements to supply 4.12 lakh tonnes of green hydrogen derivatives to Japan and Singapore. The Green Hydrogen Certification Scheme of India (GHCI) was launched simultaneously to ensure credible and transparent green hydrogen production. GHCI is India’s first certification framework to verify that hydrogen is produced exclusively using renewable energy. This certification ensures hydrogen is recognized as “green.” GHCI was launched by the Ministry of New and Renewable Energy (MNRE). The Bureau of Energy Efficiency (BEE) is the nodal agency for GHCI. It is supported by the National Green Hydrogen Mission.

Notes:
Under the Swachh Bharat Mission-Urban, Ghaziabad issued India’s first Certified Green Municipal Bond, raising ₹150 crore for a Tertiary Sewage Treatment Plant (TSTP). This bond marks a major shift towards sustainable urban infrastructure and financial innovation. The Tertiary Sewage Treatment Plant uses advanced Membrane Filtration Technologies like microfiltration, ultrafiltration, nanofiltration, and reverse osmosis (RO) to treat wastewater. The plant has a treatment capacity of 40 Million Litres per Day (MLD) and is linked to a 95 km pipeline network. It supplies treated water to over 1,400 industrial units, cutting dependence on freshwater sources.

Notes:
The Subaru Telescope in Hawaii recently used the Hyper Suprime-Cam to carry out a deep sky survey from the University of Tokyo. It reported a Sigma Eight (S8) value of 0.747, which matches earlier results from gravitational lensing studies. Sigma Eight (S8) is a key measure in cosmology that shows how matter is clustered or “clumpy” across the universe on a scale of 26 million light-years. It tells scientists how much visible and dark matter is gathered in different parts of space. This finding helps us understand how the universe evolved from a smooth early state after the Big Bang.

Notes:
The government introduced the “Depot Darpan” portal and mobile app to monitor food storage depots in real time. Ministry of Consumer Affairs, Food & Public Distribution is responsible for launching the Depot Darpan portal. The initiative aims to ensure quality and safety in food grain storage for over 80 crore beneficiaries. Depot Darpan is part of a larger push for scientific warehousing and smart storage solutions. It will allow depot managers to track infrastructure, operational efficiency, and financial performance using geo-tagged data. The platform will provide automated ratings and insights for timely improvements. All data will be 100% validated by supervisory officers and random third-party audits.

Notes:
Years of efforts by Jharkhand forest officials have succeeded with Jaigir becoming the first village to be fully relocated outside the core area of Palamu Tiger Reserve (PTR). Palamu Tiger Reserve is located in the western part of the Chotanagpur plateau and spreads across Latehar and Garhwa districts in Jharkhand. It covers a total area of 1,014 square kilometers, with 414 square kilometers as core and 600 square kilometers as buffer. It was among the first nine reserves established under ‘Project Tiger’, a conservation program launched in 1973 by the Government of India.

Notes:
The Indian Council of Agricultural Research (ICAR) has recently developed two genome-edited rice varieties, marking a major advancement in Indian agricultural science. ICAR is an autonomous body under the Department of Agricultural Research and Education (DARE), Ministry of Agriculture and Farmers Welfare, Government of India. It was founded on 16 July 1929, initially as the Imperial Council of Agricultural Research, following recommendations from the Royal Commission on Agriculture. ICAR’s headquarters is in New Delhi, and it coordinates research in agriculture, horticulture, fisheries, and animal sciences across India.

Notes:
The Centre for Earth Sciences and Himalayan Studies (CESHS) has recently drilled Northeast India’s first geothermal production well at Dirang in West Kameng district, Arunachal Pradesh. This marks a major step towards using clean and renewable energy sources in the Himalayan region. Geothermal energy is the heat from within the Earth, used to produce electricity or direct heating. CESHS achieved this breakthrough after two years of detailed geochemical and structural surveys in hot spring sites of western Arunachal Pradesh. CESHS geosciences division head Rupankar Rajkhowa confirmed the success of the drilling project. This initiative can reduce dependency on fossil fuels and support green development in remote regions.

Notes:
World Athletics Day is celebrated every year on May 7 to promote participation in sports, especially among the youth. It highlights the benefits of sports on both mental and physical health and encourages values like perseverance and teamwork. The event was first observed on May 15, 1996, by the International Association of Athletics Federations (IAAF), now called World Athletics since 2019. The idea was introduced by Primo Nebiolo, the then IAAF president, and saw participation from 50 countries. This year, World Athletics Day 2025 falls on a Wednesday and continues to promote inclusivity and environmental awareness through sports.

Notes:
The Quad countries recently conducted a Tabletop Exercise at the Asia-Pacific Centre for Security Studies in Honolulu, Hawaii to advance the launch of the Quad Indo-Pacific Logistics Network (IPLN). The Indo-Pacific Logistics Network (IPLN) aims to help Quad countries use shared logistics resources to quickly and efficiently respond to natural disasters in the Indo-Pacific region. This initiative shows the Quad’s strong commitment to a free and open Indo-Pacific and the importance of working together to face regional challenges. The Quadrilateral Security Dialogue (Quad) includes India, Japan, Australia, and the United States. It was first formed after the 2004 Indian Ocean tsunami to improve disaster relief efforts and was formalised in 2007 by Japanese Prime Minister Shinzo Abe.

Notes:
The Border Roads Organisation (BRO), under the Ministry of Defence, celebrated its 66th anniversary on May 7, 2025. It was established in 1960 with just two projects—Project Tusker (now Vartak) in the East and Project Beacon in the North. BRO now runs 18 projects across 11 States and 3 Union Territories, building roads in high-altitude and snow-bound areas. The Border Roads Organisation (BRO) functions under the Ministry of Defence.
