Dry Ports in India
News Context: Union Minister Sarbananda Sonowal informed the Lok Sabha about new dry port proposals in Andhra Pradesh and Telangana — Sri City (Tirupati district, AP) and Chityala (Nalgonda district, Telangana) are both under active consideration. The Inter-Ministerial Committee under Customs has already approved eight dry ports, including Fatehpur in Telangana, with priority given to areas of high industrial demand but limited infrastructure.
About Dry Ports — Key Facts
- A dry port is also known as an Inland Container Depot (ICD) — a logistics facility located inland, away from seaports.
- Dry ports connect inland regions with seaports and airports, serving as hubs for cargo handling, storage and transportation.
- They play a crucial role in streamlining logistics and reducing overall transportation costs.
Dry Port Operations in India
- Dry ports in India are operated by both government agencies and private players.
- CONCOR (Container Corporation of India) is the major government operator of dry ports.
- Dry ports are regulated under the Customs Act through the Inter-Ministerial Committee.

Sarnath: UNESCO World Heritage Site 2026
News Context: Sarnath was inscribed on UNESCO’s World Heritage List during the 48th session of the World Heritage Committee in Busan, South Korea — becoming India’s 45th and Uttar Pradesh’s fourth World Heritage Site. Sarnath had been on UNESCO’s tentative list since July 3, 1998, taking 28 years to secure inscription.
Religious & Historical Significance
- Sarnath is located northeast of Varanasi, near the confluence of the Ganges and Varuna rivers, Uttar Pradesh.
- Lord Buddha delivered his first sermon here, known as “Dharmachakra Pravartan.”
- It is one of the four major Buddhist pilgrimage sites — alongside Lumbini (birthplace), Bodh Gaya (enlightenment), and Kushinagar (parinirvana).
- Buddha’s Dhammacakkappavattana Sutta was composed at Sarnath.
Architectural Marvels — Key Facts
Dhamekh Stupa
Constructed by Emperor Ashoka, marking the spot where Buddhism first resonated.
Chaukhandi Stupa
Marks the place where Buddha met his first disciples.
Ashoka Pillar (Lion Capital)
An enduring symbol whose emblem graces the Indian national flag.
Mulagandhakuti Vihara
A modern temple built where Buddha spent his first rainy season in meditation.

Mega Data Centres in India
News Context: Citizens in Andhra Pradesh and Maharashtra have opposed mega data centre projects in their states. Raiden Infotech India (a Google company) is developing a 1GW AI data centre hub in Visakhapatnam, while Amazon’s hyperscale data centre (₹7,203.29 crore, 53.73 acres) is proposed in Thane, Maharashtra.
Key Environmental & Resource Concerns
Resource Usage
Enormous continuous water consumption for cooling, high electricity demand straining local grids, and large land acquisition displacing ecosystems and green cover.
Pollution Concerns
E-waste and thermal pollution risk, noise pollution from generators/cooling equipment, diesel-generator emissions, and possible groundwater contamination from coolant leaks.
Environmental & Climate Concerns
Increased carbon footprint contradicting climate commitments, threats to ecologically sensitive areas and wildlife, and aggravation of the urban heat island effect.
Regulatory Gap
Lack of Environmental Impact Assessment (EIA) for many projects raises serious regulatory concerns.
Key Facts for Prelims
- A data centre is a facility housing IT infrastructure for storing, processing and managing large volumes of data.
- Hyperscale data centres are ultra-large facilities operated by tech giants like Google, Amazon and Microsoft.
- AI data centres consume significantly more energy than conventional data storage facilities.
India’s Data Centre Policy
- India classified data centres as infrastructure in 2020, enabling access to long-term credit.
- MeitY (Ministry of Electronics and Information Technology) is the nodal ministry for data centre policy.
- India’s Digital Personal Data Protection Act, 2023 governs data storage and processing regulations.

Rice Cultivation and Methane Emissions
News Context: A study in Nature Food found GHG emissions from paddy fields have doubled since the 1960s. In 2011–2020, paddy fields produced around 1.1 billion tonnes of CO₂-e annually — a 90.4% increase over 1961–1980 emissions. About half the increase was driven by loss of soil organic carbon. Paddy fields in eastern India are among global methane hotspots, with irrigated paddy fields releasing 3.9 million tonnes of methane per year.
Why Paddy Fields Emit Methane
- Flooded fields develop low-oxygen conditions where methane-producing microbes thrive.
- Continuous irrigation, incorporating crop residues, and increasing nitrogen fertiliser use have all increased emissions.
- Over a third of paddy fields worldwide began losing carbon by the 2010s.
- A combination of improved irrigation and residue management could reduce emissions by 10% by mid-century.
- The System for Rice Intensification (SRI) technique reduces emissions by avoiding continuous flooding of fields.
- NICRA (National Innovations in Climate Resilient Agriculture) promotes alternative low-emission rice techniques.
India’s Rice Cultivation — Key Facts
- India is the world’s top rice producer (per one study) or second-largest (per another source).
- Area under paddy cultivation has increased by 25% since the 1970s; paddy now covers 55% of India’s rainfed harvested area.
- Rice requires high temperature (20–37°C), high humidity, and abundant water; it is primarily a Kharif crop, sown with the onset of monsoon.
- Major producing states: West Bengal, Uttar Pradesh, Punjab, Andhra Pradesh and Tamil Nadu, grown in alluvial soils of river valleys and irrigated plains.
