Current Affairs Terms in News This Week (19-25 April 2026)
1. Basra Memorial
Why in news?
In April 2026, the Commonwealth War Graves Commission has introduced digital name panels at the Basra Memorial in Iraq to honour 33,000 Indian Army soldiers who died in the WWI Mesopotamia Campaign (1914–1921) and were previously omitted. The initiative is an effort to correct a 100-year-long-standing omission, to ensure these soldiers are now commemorated by name alongside over 46,000 existing Commonwealth personnel.
What is it?
The Basra Memorial in Iraq is a major war memorial honouring over 40,000 Commonwealth personnel, primarily who died during the Mesopotamia Campaign, one of the British Empire’s largest military operations outside Europe in the early twentieth century.
Key Points
- The Basra Memorial in Iraq, maintained by the Commonwealth War Graves Commission (CWGC).
- For over 100 years, the names of 33,000 Indian Army soldiers who died in the First World War have been missing from the Basra Memorial in Iraq.
- Located in Iraq, the Basra Memorial was originally built near the Shatt al-Arab River in 1929, the memorial was moved to Shaiba Road, southwest of Basra, in 1997.
2. Vegetation Carbon Biomass
Why in news?
A new study published in Environmental Research: Climate indicates that India’s forests can nearly double their carbon storage capacity by 2100, predicting that vegetation carbon biomass will rise by 35 per cent to 97 per cent by 2100, driven majorly by elevated CO2 levels and increased rainfall. Over 60% of additional carbon storage is expected in arid and semi-arid regions (Rajasthan, Gujarat, western Madhya Pradesh).
What is it?
Vegetation carbon biomass refers to the total carbon stored in living plants, including leaves, trees, stems, branches, shrubs, and roots. Vegetation carbon biomass acts as a dynamic carbon sink for mitigating climate change.
Key Points
- Under the updated Nationally Determined Contributions (NDCs) for 2031-2035 approved by the Union Cabinet in March 2026, India aims to create an additional carbon sink of 3.5 to 4 billion tonnes of CO2 equivalent through enhanced forest and tree cover by 2035, compared to 2005 levels.
- According to data from the Forest Survey of India (FSI), India's total forest carbon stock increased from 6.94 billion tonnes in 2013 to 7.29 billion tonnes in 2023.
- While according to the India State of Forest Report (ISFR) 2023, India's total forest and tree cover has increased to 827,357 sq km, which represents 25.17% of the country's geographical area.
3. Methane Plumes
Why in news?
Two waste sites in India have been ranked among top methane emitters globally in the "Spotlight on the Top 25 Methane Plumes in 2025: Landfills", released by the University of California (UCLA). These sites include waste facility in Telangana's Secunderabad and Maharashtra's Mumbai.
What is it?
Methane plumes are concentrated emissions of methane (CH4), a potent greenhouse gas, released into the atmosphere from localised "super-emitter" sources like landfills, oil/gas infrastructure, and coal mines.
Key Points
- Satellite data was collected from Planet Labs' Tanager-1 and NASA's EMIT instrument on the International Space Station, analysing over 700 waste sites.
- The Jawahar Nagar landfill in Hyderabad (Secunderabad) is ranked 4th globally, emitting emits 5.9 tonnes of methane per hour, and the Kanjurmarg landfill in Mumbai is ranked 12th, emitting emits 4.9 tonnes per hour.
4. Phytoremediation
Why in news?
In April 2026, the Kankaria Coaching Depot in Ahmedabad has become India's first water-neutral railway hub, using a phytoremediation system to purify wastewater for reuse. This initiative aids in saving 1.60 lakh liters of water daily, which is equivalent to more than 300 household tanks. This Western Railway depot utilises plants to naturally treat water, absorb organic pollutants and heavy metals from wastewater.
What is it?
Phytoremediation is an eco-friendly technology that uses plants and their their associated microorganisms to remove contaminants (heavy metals, organic pollutants, pesticides) through their roots.
Key Points
- Microorganisms in the soil around plant roots (rhizosphere) break down contaminants and translocate them to shoots/leaves for removal.
- Phytoremediation treats sites contaminated with, for example, Lead, Zinc, Arsenic, Pesticides, and Petroleum hydrocarbons.
- Common plants used for phytoremediation include Indian mustard, willow, poplar, and sunflower. Other key species include vetiver grass, water hyacinth, and alfalfa.
5. Petroglyph
Why in news?
On World Heritage Day, Ladakh laid the foundation for India's first Petroglyph Conservation Park at Sindhu Ghat, Leh. Initiated by Lt. Governor Vinai Kumar Saxena along the Indus River. A Memorandum of Understanding (MoU) was signed between the UT Administration and the Archaeological Survey of India (ASI) for the joint intervention of this project.
What is it?
Petroglyphs are ancient images, symbols, or scenes (such as hunting or animals) etched, carved, or pecked directly onto rock surfaces.
Key Points
- This Petroglyph park will safeguard and display thousands of years old, endangered rock carvings collected from nearly 400 vulnerable sites across the region of Ladakh.
- Vulnerable rock art from various sites, including the Indus and Zanskar river valleys, will be relocated to this park.
- Extensive rock carvings in Ladakh, India, ranging from the Palaeolithic to the Buddhist period include early human life, ritualistic hunting scenes, various animal figures such as ibex, snow leopards, goats, and Buddhist symbols (stupas/chortens).
