Current Affairs Quiz - May 2025

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:
United Kingdom (UK)-based health charity Encephalitis International has launched a global campaign titled ‘Preventing Future Encephalitis: Climate Change and Infectious Disease’ to raise awareness about encephalitis and promote vaccination. Encephalitis is the inflammation of active brain tissues caused by infections or autoimmune responses, affecting over 1.5 million people globally every year. The campaign highlights how climate change increases encephalitis risk by creating conditions for disease-carrying vectors like mosquitoes and ticks to spread. India is among high-burden countries, with 1,548 cases of Japanese encephalitis reported in 2024 from 24 states and union territories.

Notes:
A massive explosion recently hit Iran’s Shahid Rajaee Port in Bandar Abbas, causing a huge fire and leading to many deaths and injuries. The blast is suspected to have been caused by sodium perchlorate, a chemical used in ballistic missile propulsion. Shahid Rajaee Port is Iran’s largest and most advanced commercial port. It is located near the Strait of Hormuz, a vital route through which about 26% of the world’s oil is transported. The port manages 85% of Iran’s container cargo, 52% of its oil trade, and over half of its total maritime cargo. It lies along the International North-South Transport Corridor (INSTC), linking the Indian Ocean and Persian Gulf to the Caspian Sea, Russia, and Northern Europe.

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:
Mizoram’s Animal Husbandry and Veterinary Department has reported over 3,050 pig deaths since March 2025 due to an outbreak of African Swine Fever (ASF) in the districts of Siaha, Lawngtlai, Lunglei, and Mamit. African Swine Fever (ASF) is a highly contagious viral disease that affects domestic and wild pigs with a mortality rate that can reach 100%. Though ASF does not affect humans, it severely impacts pig populations and causes major economic loss to farmers. The virus originated in Africa and has now spread globally.

Notes:
Researchers at the Indian Institute of Space Science and Technology (IIST) have developed a 3D computational model to study thermoregulation in space. It shows that microgravity consistently increases human core body temperature, which is important for long-duration space missions. Microgravity is a condition of near-weightlessness experienced when objects are in free fall around Earth, not the absence of gravity. In microgravity, normal body functions like heat regulation are altered due to changes in blood flow and metabolism. The IIST model includes sweating, shivering, clothing, and organ heat to simulate real human conditions in space.

Notes:
Tissue-cultured teak is being promoted in India as a high-yield, fast-return solution to enhance timber cultivation and trade, sparking discussions on its economic and ecological impact. Teak (Tectona grandis) is renowned for its strength, durability, and resistance to pests and water, earning it the title “king of timbers.” It is a valuable tropical hardwood used in shipbuilding, furniture, and flooring. India holds 35% of the world’s planted teak forests, with Asia contributing over 95% of global teak resources. Madhya Pradesh and Maharashtra have the largest areas of native teak forests, according to the FAO Global Teak Resources and Market Assessment 2022. Teak is native to South and Southeast Asia and grows mainly in moist deciduous forests.

Notes:
In the 2025 World Press Freedom Index by Reporters Without Borders (RSF), India ranks 151 out of 180 countries. This is a slight improvement from 159th in 2024 and 161st in 2023, but India still remains in the “very serious” press freedom category. India ranks lower than neighbours like Nepal (90th), Maldives (104th), Sri Lanka (139th), and Bangladesh (149th). Norway, Estonia, and the Netherlands are the top three performers in press freedom globally. For the first time, global press freedom is seen as in a “difficult situation” due to rising economic pressures.

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:
A recent breakthrough came as an international team of scientists successfully mapped the genome of the Saola using tissue fragments from hunter-collected remains. The Saola, scientifically named Pseudoryx nghetinhensis, is one of the rarest land mammals and is nicknamed the “Asian Unicorn” because of its secretive nature. It was first discovered in 1992 during a joint survey by the Vietnamese Ministry of Forestry and the World Wide Fund for Nature (WWF). It is listed as Critically Endangered on the International Union for Conservation of Nature (IUCN) Red List, with only about 50 to 300 individuals estimated as of 2015. The Saola lives in the evergreen forests of the Annamite Mountains along the Vietnam–Laos border, a region rich in biodiversity and rainfall.
