Why in News?
On 12th August, the Ministry of Environment, Forest and Climate Change (MoEF&CC) celebrated World Elephant Day in Coimbatore, focusing on human-elephant conflict.
World Elephant Day
- Patricia Sims of Canada and the Elephant Reintroduction Foundation of Thailand, jointly established World Elephant Day on 12th August 2012. Since then Patricia Sims continues to lead the initiative.
- The initiative, partnered with over 100 organisations, aims to raise global awareness on elephant conservation, with millions showing support each year through World Elephant Day.
Key Facts About Elephant
- Three species: There are three different species of elephant: the African Savannah elephant, the African Forest elephant and the Asian elephant.
- African elephants have larger ears shaped like Africa, Asian elephants’ ears resemble the Indian subcontinent. African elephants have two trunk “fingers”, Asians have one.
- World’s Largest Land Animal: The African Savanna (Bush) elephant is the world's largest land animal.
- Elephant Lifespan and Reproduction: Elephants can live up to 65 years. Females reach puberty at 11, have a 22-month pregnancy, and stay fertile into their late 40s. Under ideal conditions, populations can grow by 7% annually.
- Social Structure: A matriarch, usually the oldest and most respected female, leads the family.
- Tusks: Enlarged incisor teeth that grow for life. It is used for feeding, digging, and defense; targeted for ivory, making elephants vulnerable to poaching.
- Communication: Use sound, body language, touch, scent, and seismic vibrations detected through bones.
- Population Decline: 90% of African elephants lost in the past century. Asian elephant populations are down by at least 50%. Habitat loss disrupts migration routes and increases human-elephant conflict.
How India is Ensuring the Conservation of Elephants?
- Elephants in India: India hosts over 60% of the world’s wild Asian elephants (Elephas maximus), specifically the Indian elephant subspecies (Elephas maximus indicus).
- As the country’s National Heritage Animal, they play a crucial role as ecosystem engineers, aiding in seed dispersal, nutrient cycling, and climate regulation.
- As keystone (ecosystem shapers), umbrella (protecting coexisting species), and flagship species (symbols of conservation), Elephants sustain tropical forests and perennial rivers.
- Status of Asian Elephants in India: The Asian elephant, India’s largest terrestrial mammal, is found mainly in the south, northeast, and central regions.
- About 28,000–30,000 live in fragmented populations across four regions, making habitat and corridor conservation crucial.
- Protection Status of Asian Elephants: IUCN Red List (Endangered), Wildlife (Protection) Act, 1972 (Schedule I), and Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) (Appendix I).
- Project Elephant: It is a centrally sponsored scheme, launched in 1992 under MoEFCC, Project Elephant supports 22 states/UTs in conserving elephants, their habitats, and migration corridors.
- It focuses on protection, conflict mitigation, and captive elephant welfare through funding, infrastructure, and anti-poaching measures.
- The Project Tiger and Project Elephant Scheme has been merged from FY 2023-24 and is now known as Project Tiger & Elephant.
- Project RE-HAB (Reducing Elephant-Human Attacks using Bees): It is an initiative by the Khadi and Village Industries Commission (KVIC) to mitigate human-elephant conflict using "bee-fences".
- It involves strategically placing bee boxes along elephant paths to deter them from entering human habitations, thus reducing both human and elephant fatalities.
- Achievements in Elephant Conservation: The wild elephant population in India has increased from 27,669-27,719 in 2007 to 29,964 in 2017, reflecting the success of conservation efforts.
- India has designated 33 Elephant Reserves across 14 states, providing critical habitats for elephants.
- These Elephant Reserves overlap with Tiger Reserves, Wildlife Sanctuaries and Reserved Forests which are protected under Wild Life (Protection) Act, 1972, Indian Forest Act, 1927 and other local State Acts.
- The MoEFCC and state forest departments have ground-validated 150 elephant corridors across 15 states, ensuring safe movement for elephants between fragmented habitats.
- Project Elephant has also started using geospatial tools such as Land Use Land Cover (LULC) analysis and satellite data to monitor changes in elephant habitats and identify potential threats.
- Monitoring and Future Directions: The CITES-led Monitoring the Illegal Killing of Elephants (MIKE) programme monitors illegal elephant killings to guide conservation action, while Wildlife Institute of India Elephant Cell supports conservation through technical expertise, capacity building, and frontline staff training.
What are the Challenges in Elephant Conservation?
- Elephant- Train Collisions: According to a recent MoEF&CC survey, between 2009- 2024, 186 elephants died in train collisions across India, mostly in Assam, West Bengal, Odisha, Kerala, and Uttarakhand.
- Causes include railway tracks through elephant corridors, poor visibility, high train speeds, and lack of timely alerts. These areas also threaten other wildlife like gaurs, deer, and leopards.
- Habitat Loss and Fragmentation: Expanding settlements and infrastructure projects shrink and break forests into small patches.
- Identified elephant corridors in India which are essential for seasonal movement and genetic exchange, are under heavy human pressure and risk being completely blocked in some areas.
- Rising Human–Elephant Conflict: Shrinking habitats push elephants into crop fields and villages, causing major damage to livelihoods.
- This leads to 400–500 human deaths annually and over 60 elephant deaths, mostly from retaliation.
- Climate change affects elephants by disrupting habitats, water, and food sources, worsening human-elephant conflict.
- Extreme weather events like droughts and floods force elephants into human-populated areas.
- Poaching for Ivory and Other Body Parts: Targeted killing of tusked males for ivory has skewed sex ratios in many populations.
- Poaching for meat, skin, and tail hair is still prevalent, particularly in Northeast India, despite the 1989 CITES ivory trade ban.
- Infrastructure-Related Threats: Low-hanging power lines causing electrocution, and injuries from crude bombs meant for other animals pose serious risks.
- Accidental Deaths: Elephants often fall into open wells, trenches, and pits, especially in human-modified landscapes, leading to fatal injuries.
- Limited Resources for Conservation: Many elephant habitats are in remote areas with poor monitoring and patrolling infrastructure.
- For instance, Odisha’s Similipal has limited forest staff and poor access roads, leading to weak management and a higher risk of poaching and conflict.
What are Measures Needed for Elephant Conservation?
- Mitigation of Elephant- Train Collision: MoEF&CC suggested mitigation measures such as building ramps, underpasses, overpasses, and installing Intrusion Detection Systems (IDS) to monitor and alert train operators about elephant movements.
- Chili Powder Fences and Beehives: Surrounding crops with fences coated in a mixture of chili powder and waste engine oil serves as a strong deterrent to crop-raiding elephants, thereby reducing human-animal conflict.
- Installing beehives along farm boundaries deters elephants, as they avoid bees; also provides farmers with honey income.
- Banana Trap Crops: Planting fodder crops like banana and napier grass along forest edges to divert elephants from main crops.
- Strengthen Habitat Protection: Reconnect fragmented habitats through land acquisition, Gram Sabha-led consent, and voluntary relocation, as recommended by the Elephant Task Force (2010).
- Technological Interventions: Using GPS Collar Tracking monitor elephant movement in real-time for conflict prevention. Predict migration routes and hotspots for human-elephant conflict.
- Capacity building: Strengthen forest staff in remote areas with better equipment, veterinary units, and non-lethal conflict training.
- Community Participation and Empowerment: Expand programs like Gaj Yatra program and Gaj Shilpi initiative involving people to raise awareness about elephant conservation.

Strengthening Disaster Resilience in the Indian Himalayan Region
For Prelims: Flash flood, Indian Himalayan Region (IHR), Landslides, Avalanches, Glacial Lake Outburst Floods, Orographic lift
For Mains: Disaster Management in Himalayan Region, Climate Change (impacts on glaciers, extreme events, adaptation)
Why in News?
The flash flood that struck Dharali village in Uttarkashi, Uttarakhand, is a stark reminder of the increasing threat of disasters caused by extreme weather events in the Indian Himalayan Region (IHR).
What are the Factors Driving for Frequent Disasters in the Indian Himalayan Region (IHR)?
- Tectonic Activity and Earthquake Risk: The Himalayas are still rising because the Indian plate is colliding with the Eurasian plate. This ongoing tectonic movement makes the region one of the most seismically active zones in the world.
- Major fault lines like the Dhaulagiri and Indus-Ganga faults, located in India’s Seismic Zone IV and V, absorb stress from plate collisions, and sudden release of this stress triggers earthquakes.
- High earthquake potential often triggers landslides, avalanches, and even flash floods by destabilising slopes and blocking rivers.
- Example: 2005 Kashmir Earthquake (Magnitude 7.6) caused massive destruction in Jammu & Kashmir.
- Fragile Geology: The Himalayas are geologically young mountains made of sedimentary rocks, which are loose and easily eroded.
- Steep slopes mean gravity naturally pulls down loose soil and rock, leading to frequent landslides, especially after rain or seismic tremors.
- Glacial and Snow-Related Hazards: The region contains thousands of glaciers and high-altitude snowfields. Climate change is accelerating their melt, leading to the rapid expansion of Himalayan Glacial Lakes.
- In the Hindu Kush Himalayas, glaciers are melting at unprecedented rates and could lose up to 75% of their volume by 2100.
- When these lakes burst (form Glacial Lake Outburst Floods (GLOFs), they cause sudden, destructive flooding downstream.
- For instance, in 2023 a GLOF from South Lhonak Lake destroyed the Teesta III Dam at Chungthang, Sikkim.
- Extreme Rainfall Events and Cloudbursts: The IHR often receives intense, short bursts of rainfall due to orographic lift (moist air rising over mountains).
- Cloudbursts can release more than 100 mm of rain in an hour over a small area, causing flash floods and landslides.
- In July 2021, cloudbursts in Chamoli, Uttarkashi, and Pithoragarh triggered flash floods and landslides, causing severe loss of life and infrastructure.
- River Dynamics and Flash Floods: Himalayan rivers are young, fast-flowing, and carry heavy sediment loads.
- Landslides or glacial melt can block rivers temporarily, creating natural dams. When these break, sudden flash floods occur.
- Additionally, China’s proposed dam on the Brahmaputra could alter river dynamics and create a potential “water bomb” risk for India.
- Deforestation and Land Use Changes: Clearing forests for roads, hydropower projects, tourism facilities, and agriculture removes tree roots that naturally stabilise slopes, making them more prone to erosion, landslides, and excessive water runoff during heavy rains.
- In Joshimath (2023), land subsidence was linked to unregulated construction and hydropower tunnelling in fragile hill slopes.
- Projects like Char Dham caused deforestation and soil loss, especially in sensitive areas like the Bhagirathi Eco Sensitive Zone, increasing disaster vulnerability and harming glaciers.

What are the Key Committees and their Recommendations on Disaster Management in India?
- Mishra Committee (1976): It was set up to investigate the sinking of Joshimath, It recommended halting new construction in slip zones until site stability is confirmed through thorough investigation.
- It advised against cutting trees or removing boulders in landslide-prone areas for construction or road repair.
- J.C. Pant Committee (1999): It classified 31 types of disasters into five categories: water and climate-related, geological, chemical/industrial/nuclear, accident-related, and biological.
- It recommended that disaster management be included in the Constitution’s Schedule 7 and called for the enactment of national and state-level disaster laws, along with stricter enforcement of existing regulations such as building codes and safety standards.
- To ensure strong governance, the committee proposed the creation of a Cabinet Committee on Disaster Management, the institutionalization of a National Council under the Prime Minister.
- It also advocated for a dedicated Ministry of Disaster Management to coordinate efforts across various departments.
- For capacity building, the committee recommended establishing the National Centre for Calamity Management and the National Institute for Disaster Management.
- On financing, it called for reconstituting the Calamity Relief Fund, creating two new national funds for disaster response and prevention, and earmarking at least 10% of plan funds at all levels for disaster risk reduction.
- It also stressed fostering a culture of preparedness, carrying out risk assessments, training human resources, and developing standard operating procedures.
What Measures can be Adopted to Mitigate Disaster Risks in the Indian Himalayan Region?
- Develop a Comprehensive Early Warning System: Install and maintain solar-powered automated sensors and cameras at high-risk glacial lakes for real-time monitoring and timely alerts to downstream communities.
- Engineering and Geo-Technical Interventions: Structural measures like check dams, spillways, controlled drainage channels, and catchment dams must be implemented despite logistical challenges posed by high altitudes.
- These reduce the speed and volume of floodwaters during extreme weather events.
- Sustainable Tourism Management: Adopt a Green Tourism Framework with tourist caps in peak seasons, promote eco-friendly models like homestays, enforce waste and water-use norms, and direct tourism revenue to ecosystem restoration and disaster mitigation.
- Region-Specific Environmental Impact Assessment (EIA): The Himalayan ecosystem demands a customized EIA framework considering its unique geology, climate variability, and hydrology, ensuring that developmental activities do not increase disaster vulnerability.
- Revise the National Building Code for hill regions to mandate earthquake-resistant and landslide-resilient designs.
- Mainstreaming Climate and Disaster Resilience in Development: Developmental projects in the IHR must integrate disaster risk reduction as per the Sendai Framework and climate adaptation to prevent increasing hazard exposure, especially in infrastructure and urban planning.
- Integrated Watershed and River Basin Management: Adopt ridge-to-valley watershed restoration with afforestation, wetland revival, and stream bank stabilisation, restore traditional water systems.
- enforce floodplain construction limits, and establish basin-level governance for upstream–downstream disaster links.
- Community Awareness and Preparedness: Educate and engage downstream populations on cascading hazards like landslides, flash floods, and glacier melt, empower Panchayats for local preparedness, and promote participatory hazard mapping with community-owned shelters.
- Integrated Multi-agency Coordination: Encourage collaboration between National Disaster Management Authority (NDMA), National Remote Sensing Centre (NRSC), Central Water Commission, State governments, and scientific institutions for risk assessment, monitoring, and mitigation.
Conclusion
Balancing development with ecological safeguards is essential for Himalayan stability. Strengthening land-use regulations, climate-resilient infrastructure, and community preparedness supported by initiatives like the National Mission on Himalayan Studies (NMHS) can reduce disaster risks while advancing goals for safe and sustainable settlements.

Biochar-Led Carbon Drawdown for Sustainable Growth
Why in News?
With the Indian carbon market set to be launched in 2026, CO₂ removal technologies such as biochar are poised to play a pivotal role in reducing emissions and ensuring sustainable growth.
What are the Key Statistics Related to India's CO2 Emissions?
- Total Emissions: India contributes only 4% of global cumulative GHG emissions (1850–2019), with per capita emissions at about one-third of the world average.
- India reduced its GDP emission intensity by 36% (2005–2020).
- India is the 3rd largest emitter of greenhouse gases after China and the USA.
- Emission Hotspots:
- India’s power sector, dominated by coal-based thermal plants, is the largest source of CO₂ emissions, contributing about 50% of the country’s fuel-related emissions.
- The transport sector, especially road transport, accounts for around 12% of India’s energy-related CO₂ emissions.
- These sectoral trends underscore the urgency of advancing scalable CO₂ removal pathways, with solutions like biochar offering significant potential to offset emissions and support India’s low-carbon transition.
What are the Potential Applications of Biochar?
- About: Biochar is a carbon-rich charcoal produced through pyrolysis of agricultural residue and organic municipal waste.
- India produces over 600 million tonnes of agricultural residue and 60 million tonnes of municipal waste yearly. Much of this is burned or dumped, causing air pollution and greenhouse gas emissions.
- Utilizing 30-50% of this waste for biochar could remove around 0.1 gigatonnes of CO₂-equivalent each year.
- Potential Applications of Biochar:
- Carbon Capture: Biochar’s stable structure enables it to sequester carbon in soil for 100 to 1,000 years, making it an effective long-term carbon sink that also enhances soil organic carbon and aids in the restoration of degraded soils.
- Modified biochar can adsorb CO₂ from industrial exhaust gases, but its efficiency is currently lower than conventional carbon capture technologies.
- Power Generation: Biochar production through pyrolysis in India can generate approximately 20–30 million tonnes of syngas and 24–40 million tonnes of bio-oil as valuable byproducts.
- Syngas can produce 8–13 Terawatt-hour (TWh) of electricity annually.
- Bio-oil can substitute 12–19 million tonnes of diesel or kerosene, helping reduce crude oil imports and cutting fossil fuel emissions by over 2%.
- Agriculture: Applying biochar improves water retention, especially in semi-dry and nutrient-depleted soils. This leads to a 30-50% reduction in nitrous oxide emissions, a potent greenhouse gas with 273 times the warming potential of CO₂, making its mitigation critical for climate action.
- Construction Sector: Incorporating 2-5% biochar into concrete improves mechanical strength, increases heat resistance by 20%, and captures approximately 115 kg of CO₂ per cubic metre.
- Wastewater Treatment: Biochar is a cost-effective way to clean polluted water. India produces over 70 billion litres of wastewater daily, but 72% remains untreated.
- Carbon Capture: Biochar’s stable structure enables it to sequester carbon in soil for 100 to 1,000 years, making it an effective long-term carbon sink that also enhances soil organic carbon and aids in the restoration of degraded soils.
What are the Other Key CO₂ Removal Technologies?
- Bio-based Solutions:
- Afforestation & Reforestation: Large-scale tree planting to absorb atmospheric CO₂.
- Agroforestry: Integrating trees with crops/livestock for carbon sequestration and livelihood benefits.
- Soil Carbon Sequestration: Practices like conservation tillage and cover cropping to enhance soil organic carbon.
- Ocean-based Solutions:
- Artificial Upwelling/Downwelling: Moving nutrient-rich waters to surface or transporting CO₂-rich surface waters to depths.
- Seaweed Cultivation & Sinking: Farming fast-growing seaweeds for carbon storage via harvest or sinking.
- Bioenergy with Carbon Capture and Storage (BECCS): It combines biomass energy with CO₂ capture and geological storage, enabling renewable power with net negative emissions.
- Direct Air Capture (DAC): It involves chemical processes extracting CO₂ directly from air for underground storage or product use.
- Eg: Climeworks (Switzerland), Carbon Engineering (Canada).
- Carbon Capture, Utilisation, and Storage (CCUS): CCUS captures CO₂ from industrial emissions for reuse (synthetic fuels, building materials) or storage.

In a historic first, Tuvalu is set to relocate its population to Australia under the Falepili Union Treaty (2023), marking the world’s first planned migration due to climate change-induced sea-level rise.
- Falepili Union Treaty: Australia will accept 280 Tuvaluans annually as permanent residents through a ballot-based “climate visa” starting in 2025, granting them equal rights to health care, education, housing, and jobs.
- Residents may return if conditions improve, though worsening floods and storms make this unlikely.
- Reason for Migration: Rising sea levels threaten Tuvalu’s existence, with NASA predicting submergence of most of its land by 2050.
- Tuvalu's average elevation is only 2 meters above sea level, making the nation highly prone to floods, storms, and coastal erosion.
Tuvalu
- Formerly known as the Ellice Islands, Tuvalu is a Polynesian island country located midway between Hawaii and Australia in the South Pacific Ocean. It comprises nine islands (four reef islands and five coral atolls).
- Tuvalu, with Funafuti as its capital, gained independence from the United Kingdom in October 1978.
- With no rivers, it has a tropical climate and one of the smallest populations in the world, around 11,000.
- Tuvalu, a United Nations designated Least Developed Country, has a public sector–dominated economy supported by fishing licences.
- The Tuvalu Trust Fund, set up with contributions from Australia, New Zealand, the UK, Japan, and South Korea, provides financial stability and funds development projects such as upgrading schools and fisheries centres.

NASA’s Lunar Nuclear Reactor
NASA is accelerating its plans to build a nuclear reactor on the moon by 2030, with the goal of establishing a permanent human presence on the lunar surface, all while adhering to the Artemis Accords.
- Reactor Specifications: The reactor is expected to generate 100 kilowatts of power, which is smaller than on-shore wind turbines (typically generating 2-3 megawatts).
- Nuclear reactors are explored because solar power is unreliable on the Moon due to extended darkness, and nuclear energy provides consistent power for habitats, rovers, and missions, particularly in shadowed craters.
- The UN's 1992 Principles Relevant to the Use of Nuclear Power Sources in Outer Space recognize nuclear energy as essential for deep-space missions, especially when solar power is insufficient.
- Global Competition: Nasa’s push comes after similar plans by China and Russia to set up automated nuclear power stations on the moon by 2035.
- Other countries, including India and Japan, are also trying to explore the moon and establish human settlements.
- Legal Framework: The 1967 Outer Space Treaty allows peaceful use of nuclear power in space, setting guidelines for transparency, safety, and international cooperation.
- Also, the Artemis Accords provides for international cooperation in space exploration, emphasizing transparency, peaceful use, and responsible use of space resources.
