Environment, Biodiversity & Climate Change

The Directorate General of Lighthouses and Lightships (DGLL), through its Port Blair (Sri Vijaya Puram) directorate, has sought clearance from the Andaman and Nicobar Islands Coastal Zone Management Authority and the Environment Ministry to undertake protection and development work — including a convention centre and a museum — at Indira Point, India's southernmost point on Great Nicobar Island. The site falls in the highly protected ICRZ-IA and ICRZ-IVA categories, where most construction is prohibited. This article explains what Indira Point is, the Island Coastal Regulation Zone framework under the CRZ Notification, 2019, why the location is ecologically sensitive, and the conservation-versus-development questions the proposal raises.

Madhya Pradesh enforcement agencies are preparing a coordinated crackdown on wildlife trafficking through railway routes after seizure data reportedly revealed organised interstate networks moving protected freshwater turtles from northern river systems to domestic and overseas markets. The issue is important for UPSC because it connects Wildlife Protection Act, 1972, CITES, river biodiversity, organised crime, rail-based trafficking routes and India’s conservation governance.

The Union Environment Ministry's expert committee under Sanjay Kumar is moving towards finalising the Ecologically Sensitive Area (ESA) for the Western Ghats, possibly through a phased, state-wise notification, even as Kerala and Karnataka continue to resist. With the sixth draft notification of about 56,825 sq km set to lapse by end-July 2026, the long-pending conservation regime for one of India's richest biodiversity hotspots is again in focus. This article explains what an ESA is and its legal basis, the contrast between the Gadgil and Kasturirangan reports, the journey of the six draft notifications, the biodiversity and monsoon significance of the Ghats, and the conservation-versus-development debate that has kept consensus elusive for over a decade.

The Zoological Survey of India has identified four sites on the west coast of Great Nicobar Island for translocating coral colonies and giant clams likely to be affected by the proposed Galathea Bay transshipment port under the Great Nicobar mega project. The development has revived UPSC-relevant questions on coral reef conservation, environmental clearance, ICRZ rules, Schedule-I species, tribal safeguards and the balance between strategic infrastructure and fragile island ecology.

The Great Nicobar Island Development Project has returned to the spotlight after government sources defended the roughly Rs 81,000-crore plan as a strategically vital national initiative, rejecting the charge that it is "one of the biggest scams" and a crime against the island's natural and tribal heritage. The sources clarified that the existing INS Baaz runway will not be extended to the planned 10,000 feet because of the ecological and tribal costs, and argued that India's wider maritime needs cannot be met by expanding defence assets alone. This article explains the project's components, the strategic geography of Great Nicobar, the logic of a transshipment port at Galathea Bay, and the environmental and tribal-rights concerns at the heart of the ecology-versus-security debate.

The first comprehensive Delhi Bird Atlas, released on 5 June 2026, ranks Delhi as the world's second-richest national capital for bird diversity after Nairobi, with 471 species on the city's bird list. Prepared by the Delhi Forest Department with Bird Count India as a citizen-science project, it maps the distribution and abundance of birds using a grid-based method and links Delhi's richness to the Aravalli Ridge, the Yamuna and Sahibi floodplains, and the Central Asian Flyway. This article explains what a bird atlas is, the Central Asian Flyway and global flyways, the species of conservation concern recorded, the citizen-science and eBird method, and India's framework for protecting migratory birds and wetlands — all mapped to the UPSC syllabus.

A cluster of Asiatic lion deaths in Gujarat's Gir landscape in late May 2026, linked to the suspected tick-borne disease Babesiosis, has revived the debate on whether India's only wild lion population is dangerously vulnerable. This article explains Babesiosis and Canine Distemper Virus, the single-population and genetic-bottleneck risk, the 2025 lion census, Project Lion, the stalled Kuno translocation, and the full conservation, legal and international framework for the Asiatic Lion.

The Maharashtra government has exempted a large iron-ore mining and processing project in Gadchiroli from wildlife clearance, stating the site does not fall in any tiger corridor — a claim that official maps and the NTCA-approved Tiger Conservation Plan appear to contradict. The project, involving diversion of 9.4 sq km of forest land by Lloyds Metals & Energy, overlaps the ecologically vital Tadoba–Indravati tiger corridor. This article explains what a tiger corridor is, the legal framework under the Wildlife (Protection) Act, 1972 (Section 38-O), Project Tiger, NTCA, the difference between forest, wildlife and environmental clearances, the role of the Forest Rights Act and PESA, and the development-versus-conservation debate this case raises.

The Wildlife Institute of India (WII) has prepared a 10-year management plan for Delhi's only wildlife sanctuary — Asola Bhatti Wildlife Sanctuary in the Aravalli range — revealing that the invasive alien tree species Prosopis Juliflora (Vilayati Kikar) alone covers a staggering 63.48% of the sanctuary's landscape, posing a severe ecological threat. This article explains the WII management plan in detail, the invasive species crisis, the Aravalli–Delhi Ridge ecology, biological invasion impacts, India's legal framework on Invasive Alien Species under the Wildlife (Protection) Act and Convention on Biological Diversity, and the broader conservation challenges facing Delhi's last green lung.

While many parts of India are struggling with the LPG crisis caused by rising prices and supply issues due to the West Asia conflict, the small village of Ekauni in Chandauli district of Uttar Pradesh remains completely untouched. All 500 residents here cook using piped biogas produced from cow dung in a community plant set up in 2022. The story highlights how a simple, locally managed biogas system can provide reliable and cheap clean cooking fuel to rural families.

On March 28, 2026, the Rajasthan High Court issued an important order banning night safaris and the use of drones, spotlights, torch lights and similar devices in the Jawai Leopard Reserve in Pali district. The court acted on a Public Interest Litigation (PIL) filed by local resident Apoorva Agrawat. It directed the state government to ensure no wildlife spotting activities take place after 7 pm or before 6 am. The bench noted that unregulated tourism, especially at night, was causing serious disturbance and stress to leopards and other animals. This order aligns with similar restrictions already followed in places like Ranthambore National Park.

On March 26, 2026, a chick of the critically endangered Great Indian Bustard (GIB) hatched in the grasslands of Kutch, Gujarat, for the first time in nearly ten years. This success came through a special “jumpstart” conservation technique where a fertile egg from a captive breeding centre in Sam, Rajasthan, was transported 770 km by road in a portable incubator and placed in the nest of a wild female GIB in Naliya, Gujarat, replacing her infertile egg. The effort was coordinated by the Ministry of Environment, Forest and Climate Change, forest departments of both states, and the Wildlife Institute of India. Union Environment Minister Bhupender Yadav and Gujarat Forest Minister Arjun Modhwadia described it as a major milestone for the species.

On March 25, 2026, India released its third set of Nationally Determined Contributions (NDCs) under the Paris Agreement, setting fresh climate goals for 2035. The new targets include a 47% reduction in emissions intensity of GDP, 60% share of non-fossil sources in electricity capacity, and creation of an extra 3.5-4 billion tonnes of carbon sink. This update comes at a time when global climate action is slowing due to policy shifts in the United States and lack of enough money from rich countries for climate projects in developing nations.

The United States has eased some sanctions on Venezuela, allowing American companies like Chevron to increase imports of its heavy crude oil. This move, highlighted in recent reports, aims to match the needs of US Gulf Coast refineries while keeping global oil prices stable amid rising domestic production of light oil. Venezuela, with the world's largest heavy oil reserves, is seeing a revival in exports to the US after years of restrictions, signaling a pragmatic shift in US energy policy in 2026.

A new study by the Centre for Research on Energy and Clean Air (CREA) revealed that India's coal-fired power generation fell by 3% in 2025 compared to 2024, marking the first year-on-year decline in half a century without pandemic influence. This shift highlights the rapid rise in clean energy sources like solar and wind, which outpaced overall power demand growth, signaling a potential peak in coal use and supporting India's climate goals.

US President Donald Trump signed a proclamation on January 08, 2026, withdrawing the United States from 66 international organizations, including 31 UN bodies and key climate entities like the UNFCCC and IPCC. This move, aimed at prioritizing "America First" interests, cuts US funding and participation, potentially reshaping global governance and opening opportunities for China to expand its influence in areas like climate diplomacy and development aid.

Renowned ecologist and environmentalist Madhav Gadgil passed away at the age of 83 after a brief illness, leading to renewed discussions on his pioneering 2011 Western Ghats Ecology Expert Panel (WGEEP) report. This report highlighted the need for strict conservation in the ecologically fragile Western Ghats region, but it faced significant opposition from states and industries, resulting in its partial implementation through a diluted version.

On January 08, 2026, the United States announced its withdrawal from the UNFCCC, a broader step than just leaving the Paris Agreement. This decision could disrupt worldwide climate cooperation, reduce funding and technology sharing for countries like India, and allow China to take a bigger role in leading global climate actions during a time of increasing environmental challenges.

The President of India, Smt Droupadi Murmu, presented the National Energy Conservation Awards 2025 and prizes for the National Painting Competition on Energy Conservation during the celebrations of National Energy Conservation Day in New Delhi. This event underscores the government's focus on promoting energy efficiency, reducing carbon emissions, and aligning with sustainable development goals, which are crucial for India's environmental commitments under global frameworks like the Paris Agreement.

The Standing Committee of the National Board for Wildlife has recommended reinstating the Rhesus Macaque under Schedule II of the Wildlife Protection Act, 1972, to restore legal safeguards against cruelty, exploitation, and illegal trade, following requests from animal welfare organizations and deliberations on managing growing human-monkey conflicts across several states.

The Standing Committee of the National Board for Wildlife has recommended approval for 12 key defence projects in Ladakh's protected wildlife sanctuaries, citing the need for high operational preparedness due to increasing assertiveness by China's People's Liberation Army along the Line of Actual Control, following lessons from the 2020 border conflicts.

The Himachal Pradesh government filed an affidavit with the Supreme Court on October 27, 2025, clarifying that logs seen floating in viral flood videos from Ravi and Beas rivers were uprooted trees from cloudbursts and landslides, not illegal felling. This addresses the court's September suo motu notice after August floods killed 320 people, amid rising fears of deforestation in the sensitive Himalayan belt, where climate change is making such events deadlier and more frequent.

On October 9, 2025, the Supreme Court of India issued an order pausing all work on Haryana's proposed jungle safari park in the Aravalli hills, following a petition highlighting potential ecological harm. This decision comes amid growing debates on balancing development projects like eco-tourism with the protection of fragile ecosystems, especially in the Aravallis, which serve as a vital green barrier for northern India.

The Ministry of Environment, Forest and Climate Change (MoEFCC) has issued an office memorandum exempting mining projects for atomic, critical, and strategic minerals from mandatory public consultations under the Environment Impact Assessment (EIA) Notification, 2006. This step, reported by The Indian Express on September 11, 2025, responds to requests from the Ministry of Defence and the Department of Atomic Energy (DAE), aiming to expedite clearances for minerals vital to national security, defence equipment, and atomic energy programs amid India's heavy import dependence. The move aligns with recent policy shifts to boost domestic production but has raised questions about environmental transparency and community involvement.

The Union Ministry of Environment, Forest and Climate Change (MoEFCC) has decided to invite public objections and reconsider the proposed boundary alteration plan for Sariska Tiger Reserve in Rajasthan, following Supreme Court criticism of the expedited approval process. This development, reported in The Indian Express on September 11, 2025, stems from concerns that the changes could allow over 50 closed mining sites to reopen near the reserve, potentially harming wildlife habitats and the Aravalli ecosystem. The court's August 6, 2025, hearing highlighted procedural flaws, prompting the ministry to issue a draft notification for transparency and compliance with legal requirements.

The Union government has approved the expansion of the Sundarbans Tiger Reserve in West Bengal by 1,044 sq km, making it the second-largest tiger reserve in India after the Nagarjunasagar-Srisailam Tiger Reserve.
