How AI helped community-led development in Rajasthan

---

Why In News ?

• AI4WaterPolicy pilot in Rajasthan (Sirohi and Pali) demonstrated how AI-enabled listening systems can improve last-mile governance responsiveness by strengthening feedback loops in water management programmes.

Relevance

• GS Paper II (Governance): E-governance, participatory governance, decentralisation
• GS Paper III (Science & Tech): AI in public policy, Digital Public Infrastructure

Practice Question

Q. Artificial Intelligence can transform governance from a delivery-centric to a listening-centric model. Discuss with suitable examples. (250 words)

Static Background And Basics

• India’s governance architecture relies heavily on last-mile delivery systems, including frontline workers and community volunteers under schemes like Jal Jeevan Mission and Panchayati Raj institutions.
• Traditional service delivery assumes an information deficit model, where citizens lack knowledge, while actual gaps often lie in institutional responsiveness, coordination failures, and behavioural barriers.
• AI in governance is increasingly used for advisory services, chatbots, and entitlement delivery, but its role in feedback collection and system redesign remains underexplored.

Innovative Approach: Listening-Oriented AI

• The AI4WaterPolicy project used AI not to disseminate information but to capture qualitative insights from communities, shifting focus from top-down delivery to bottom-up governance feedback.
• AI chatbot conducted 352 structured interviews across 50 villages in six months, using WhatsApp voice and text in local dialects, ensuring accessibility and inclusivity.
• Responses were automatically transcribed, translated, and thematically analysed, enabling rapid synthesis of field-level insights without extensive manual effort.

Key Insights Generated

• Community feedback revealed tangible outcomes, such as improvement in groundwater levels from 150 feet to below 100 feet, reflecting local ownership and programme impact.
• Highlighted gendered burden, where women balanced household responsibilities with community water management roles, indicating need for gender-sensitive interventions.
• Identified institutional bottlenecks, including delays in Panchayat approvals and limited awareness of procedures, which hindered timely implementation of water projects.

Governance Impact And Policy Innovation

• Real-time insights enabled mid-cycle policy correction, with implementing agency redesigning training to include Panchayati Raj orientation and inter-departmental coordination workshops.
• Follow-up data showed over 50% increase in community engagement with government officials, improving confidence, participation, and accountability mechanisms.
• Demonstrates shift from reactive governance to adaptive governance, where policies evolve dynamically based on continuous feedback.

Conceptual Shift: From Responsive To Listening Systems

• Responsive systems treat feedback as input for predefined outputs, whereas listening systems reshape interventions based on community experiences and contextual realities.
• AI enabled safe, private communication channels, reducing social barriers like hesitation due to caste, gender, or power hierarchies in face-to-face interactions.
• Rapid analysis of qualitative data allowed timely intervention within the same programme cycle, unlike traditional monitoring systems with delayed feedback loops.

Role Of Human Intermediaries

• Success depended on community-based volunteers (‘Pani Mitras’) who facilitated trust, access, and participation, highlighting importance of human-AI complementarity.
• Field institutions like Centre for Microfinance (CmF) ensured digital access, contextual understanding, and validation of AI-generated insights, preventing technological exclusion.
• Reinforces principle that AI should augment, not replace, grassroots governance actors, especially in socially complex rural environments.

Challenges And Limitations

• Digital divide based on gender, caste, and income restricts equitable access to AI tools, requiring offline support systems and assisted access mechanisms.
• AI models may miss contextual nuances, cultural sensitivities, and power dynamics, necessitating human validation and interpretation.
• Scaling such models requires institutional capacity, funding, and integration with existing governance frameworks, which may vary across states.

Strategic Significance

• Demonstrates potential of AI in improving governance efficiency, transparency, and accountability, especially in resource management sectors like water and agriculture.
• Aligns with India’s broader push for Digital Public Infrastructure (DPI) and AI-driven governance under Digital India framework.
• Offers replicable model for sectors requiring behavioural change, community participation, and decentralized decision-making.

Way Forward

• Integrate AI-enabled feedback systems into flagship programmes like Jal Jeevan Mission and rural development schemes, institutionalizing real-time learning loops.
• Develop ethical AI frameworks ensuring data privacy, inclusivity, and transparency in public service delivery systems.
• Strengthen capacity building of frontline workers to effectively use AI tools, ensuring synergy between technology and human governance systems.
• Promote multi-stakeholder collaboration among government, research institutions, and civil society to scale context-sensitive AI solutions.

Prelims Pointers

• AI4WaterPolicy used AI chatbots via WhatsApp for collecting qualitative governance data in local dialects.
• Focus was on listening systems rather than information dissemination, improving policy responsiveness and last-mile delivery.

Rise of Extreme Rainfall Events

---

Why In News ?

• India Meteorological Department forecast 92% of Long Period Average (below-normal monsoon), yet rising extreme rainfall events (>21 cm/day) indicate continued flood risks despite overall rainfall deficit.

Relevance

• GS Paper I (Geography)
  • Monsoon variability, climate change
• GS Paper III (Environment & Disaster Management)
  • Floods, urban resilience, climate adaptation

Practice Question (Mains)

Q. “Below-normal monsoon does not necessarily imply reduced flood risk in India.” Analyse in the context of rising extreme rainfall events. (250 words)

Static Background And Basics

• Indian monsoon exhibits high spatial and temporal variability, meaning seasonal averages do not reflect intra-seasonal distribution, intensity, or regional concentration of rainfall events.
• IMD classifies “extremely heavy rainfall” as ≥21 cm in 24 hours, earlier threshold being ≥244.5 mm before 2016, revised to ≥204.5 mm, improving detection but not altering trend.
• Monsoon rainfall variability is influenced by ENSO, Indian Ocean Dipole, and climate change, making prediction of extreme events more complex than seasonal forecasts.

Key Trend: Rise Of Extreme Rainfall Events

• Number of extreme rainfall events increased from ~60–70 annually (2008–11) to consistently above 100 since 2017, reaching 181 events in 2024 and ~160 in 2025.
• These events constitute <0.1% of total rainfall events, yet disproportionately contribute to floods, landslides, and urban disasters, highlighting skewed rainfall distribution patterns.
• Increasing trend persists even when measured using higher pre-2016 thresholds, confirming genuine intensification due to climatic factors rather than classification changes.

Climate Change Linkages

• Warmer atmosphere holds ~7% more moisture per °C rise (Clausius-Clapeyron relation), leading to short-duration, high-intensity rainfall bursts instead of steady precipitation.
• Climate change has increased frequency, intensity, and unpredictability of extreme weather events, including heatwaves, floods, and cyclones, complicating disaster preparedness.
• India has witnessed at least one major rainfall-induced disaster annually since 2013, including Kedarnath (2013), Kerala floods (2018), Himachal-Delhi floods (2023).

Why Below-Normal Rainfall Does Not Prevent Floods ?

• Temporal concentration of rainfall leads to heavy downpours within short durations, overwhelming drainage systems despite lower seasonal totals.
• Regional disparities mean some areas receive excess rainfall while others face deficits, masking flood risks in national averages like 92% LPA forecast.
• Extreme rainfall events trigger flash floods, cloudbursts, and landslides, independent of overall monsoon performance.

Urban And Governance Dimensions

• Rapid urbanization has increased vulnerability due to encroachment of floodplains, loss of wetlands, and inadequate drainage infrastructure.
• Major cities like Mumbai, Chennai, Bengaluru, Delhi, Hyderabad have experienced multiple flooding events in the last decade, reflecting systemic urban planning failures.
• Floods caused ~17,500 deaths (2012–2021) and accounted for over 55% of state disaster expenditure (2019–24), indicating high economic and social costs.

Scientific And Forecasting Challenges

• Weather systems are chaotic in nature, where minor initial variations lead to large forecast differences, limiting precision in predicting exact rainfall intensity (e.g., 250 mm vs 500 mm).
• Increasing granularity in forecasts (time/location) enhances usefulness but also increases uncertainty, posing challenges for early warning systems.
• Climate change further amplifies model uncertainties, requiring continuous improvements in data, modelling, and computational capacity.

Policy Shift: From Drought To Flood Risk

• Earlier policy focus was on rainfall deficiency and drought, but India has improved resilience through irrigation, food buffer stocks, and diversification.
• Current challenge is localized extreme rainfall, particularly in dense urban agglomerations, requiring shift toward flood risk management and climate adaptation strategies.

Way Forward

• Strengthen urban flood management through restoration of wetlands, floodplain zoning, and climate-resilient infrastructure planning to absorb extreme rainfall shocks.
• Enhance early warning systems using high-resolution weather models, Doppler radars, and real-time data integration, improving disaster preparedness and response.
• Integrate climate adaptation into urban governance, ensuring coordination between municipal bodies, disaster management authorities, and planning agencies.
• Promote nature-based solutions like urban forests, permeable surfaces, and water retention systems to reduce runoff and mitigate flood risks.

Prelims Pointers

• Extremely heavy rainfall (IMD): ≥21 cm in 24 hours.
• Long Period Average (LPA): Benchmark for monsoon performance; 92% LPA = below-normal rainfall.
• Extreme rainfall events are increasing despite stable or declining seasonal averages, due to climate change effects.

B’nei Menashe Migration

---

Why In News ?

• Around 250 members of the B’nei Menashe community from Manipur and Mizoram migrated to Israel under a government-backed relocation programme, reviving debate on identity, migration, and diaspora linkages.

Relevance

• GS Paper I (Society)
  • Identity, migration, tribal issues
• GS Paper II (IR)
  • India–Israel relations, diaspora diplomacy

Practice Question

Q. The migration of B’nei Menashe raises complex questions of identity, religion, and geopolitics. Examine. (250 words)

Static Background And Basics

• B’nei Menashe are a Jewish-identifying tribal group (~7,000 people) belonging to Mizo and Kuki communities in Northeast India, claiming descent from the Biblical Tribe of Manasseh.
• The concept of “Lost Tribes of Israel” originates from 722 BCE Assyrian conquest, when 10 Israelite tribes were exiled and dispersed, forming part of Jewish historical and religious tradition.
• These tribes include Reuben, Simeon, Dan, Naphtali, Gad, Asher, Issachar, Zebulun, Ephraim, and Manasseh, with global searches for descendants continuing over centuries.

Historical Evolution Of Identity

• The belief among Northeast tribes emerged during 19th-century Protestant missionary activity, which linked local traditions with Biblical narratives and Israelite origins.
• In 1951, Mizo spiritual leader Challianthanga (Mela Chala) claimed divine revelation identifying Mizo-Kuki-Chin tribes as descendants of Israel, catalysing identity transformation.
• Organized Judaising movement intensified post-1970s, with support from Israeli organisation Amishav, promoting return of “lost tribes” to Israel.

Institutional And Political Recognition

• In 2005, the Chief Rabbinate of Israel recognised B’nei Menashe as “Lost Seed of Israel”, allowing migration subject to formal religious conversion.
• Jewish organisations like Shavei Israel facilitated migration from the 2000s to 2020, followed by community-led initiatives like Degel Menashe.
• Migration aligns with Israel’s Law of Return (1950), enabling Jews worldwide to settle in Israel, though B’nei Menashe require conversion validation due to contested ancestry.

Scientific And Anthropological Debate

• Genetic studies, including those referencing Cohen Modal Haplotype, have produced inconclusive evidence, failing to establish definitive Israelite lineage.
• Institutions like Technion-Israel Institute of Technology have questioned earlier findings, highlighting limitations of genetic proof in tracing ancient migrations.
• Anthropologically, identity is shaped by cultural practices, oral traditions, and religious transformation, not solely genetic lineage.

Socio-Political And Cultural Implications

• Raises questions of ethnic identity, religious conversion, and diaspora politics, especially in India’s diverse tribal and religious landscape.
• Migration may lead to demographic and cultural shifts in Northeast India, particularly among Kuki-Mizo tribal communities.
• In Israel, integration challenges include language barriers, economic adaptation, and social assimilation into mainstream Jewish society.

India’s Perspective

• India follows a non-interference approach, viewing migration as a matter of religious freedom and individual choice, without official endorsement of historical claims.
• However, issue intersects with internal security and ethnic dynamics in Northeast India, where identity politics and migration patterns are sensitive.

Global And Diplomatic Dimensions

• Reflects Israel’s broader policy of ingathering Jewish diaspora, reinforcing its identity as a Jewish homeland.
• Highlights intersection of religion, geopolitics, and migration, influencing India-Israel relations in socio-cultural domains beyond strategic ties.

Challenges And Concerns

• Authenticity debate over historical claims creates tension between religious recognition and scientific evidence.
• Migration may lead to loss of indigenous cultural practices among B’nei Menashe communities over generations.
• Integration issues in Israel may result in economic marginalisation or social exclusion, similar to other migrant Jewish communities.

Way Forward

• Encourage balanced academic research integrating genetics, anthropology, and history to better understand origins without politicisation.
• Ensure cultural preservation initiatives for Northeast tribes, irrespective of migration choices, safeguarding indigenous identity.
• Strengthen India-Israel cultural cooperation frameworks, facilitating smoother migration, integration, and diaspora engagement.

Prelims Pointers

• Lost Tribes of Israel: 10 tribes exiled after 722 BCE Assyrian conquest.
• B’nei Menashe: Tribal group from Manipur and Mizoram claiming descent from Tribe of Manasseh.
• Law of Return (Israel): Grants Jews right to migrate and settle in Israel.

International Waters & Strait of Hormuz

---

Why In News ?

• Escalation in the Strait of Hormuz involving Iran–U.S. confrontation, ship interceptions, and transit restrictions has raised questions on legality under international maritime law and UNCLOS provisions.

Relevance

• GS Paper II (IR): International law, UNCLOS, maritime disputes
• GS Paper III (Security): Energy security, global commons

Practice Question

Q. Discuss the legal regime governing international straits under United Nations Convention on the Law of the Sea. Examine the implications of tensions in the Strait of Hormuz for India. (250 words)

Static Background And Legal Framework

• United Nations Convention on the Law of the Sea (1994) establishes oceans as global commons, guaranteeing freedom of navigation on high seas with limited exceptions like piracy, stateless vessels, or UN-authorised actions.
• Maritime zones include territorial waters (12 nautical miles), Exclusive Economic Zones (200 nautical miles), and high seas, each governed by distinct legal rights and obligations.
• In international straits, UNCLOS provides for “transit passage”, ensuring continuous and unobstructed navigation for all vessels, including merchant and military ships.

Legal Status Of Strait Of Hormuz

• The strait is a strategic chokepoint handling ~20% of global oil trade, with Iran and Oman’s territorial waters overlapping, leaving no high seas corridor at its narrowest point.
• Under UNCLOS, it qualifies as an international strait, where transit passage overrides national sovereignty, limiting coastal states’ regulatory powers over navigation.
• Iran cannot block, delay, or impose arbitrary tolls on transit passage, though it can enforce limited conditions like continuous movement and adherence to designated routes.

Can Iran Restrict Transit?

• Iran cannot legally deny passage to merchant vessels exercising transit rights, as this would violate UNCLOS provisions on freedom of navigation in straits used for international navigation.
• However, Iran can impose non-discriminatory regulations related to safety, environmental protection, and navigation control, provided they do not impede transit passage.
• Actions like detaining vessels, firing upon ships, or imposing toll fees reportedly exceeding $1 million per vessel may constitute violations of international maritime law.

Legality Of U.S. Blockade

• U.S. sanctions and blockade measures are based on domestic law and unilateral economic policy, not authorized by the United Nations Security Council, raising questions about international legality.
• A blockade on the high seas without UN approval or wartime justification may violate freedom of navigation principles under UNCLOS, especially if applied to neutral vessels.
• However, the U.S. often justifies actions through flag state consent, sanctions enforcement, or security concerns, though these remain legally contested.

Legal Position On Interceptions

• Interception of vessels on the high seas is generally prohibited, except under specific conditions such as piracy, stateless vessels, or explicit UN Security Council authorization.
• Doctrine of “hot pursuit” allows interception if a vessel has committed an offence in territorial waters and is pursued continuously into international waters.
• Boarding or seizure without legal basis may be considered violation of sovereignty and international maritime law, potentially escalating into diplomatic or military conflict.

Role Of International Institutions

• International Maritime Organization (IMO) is responsible for ensuring maritime safety, security, and freedom of navigation, and can mediate disputes and propose operational solutions.
• IMO has condemned attacks on commercial vessels and restrictions on navigation, and is working on evacuation and safe transit mechanisms in the region.
• However, enforcement powers are limited, and resolution often depends on diplomatic negotiations and geopolitical balance among major powers.

Strategic And Economic Implications

• Disruptions in Hormuz can impact global energy markets, as nearly one-fifth of global oil supply passes through the strait, affecting prices and supply chains.
• For India, which imports over 85% of its crude oil, instability threatens energy security, inflation control, and external sector stability.
• Increased militarisation of the strait raises risks of regional conflict escalation, supply chain disruptions, and maritime insecurity.

What Can Happen Next ?

• Continued escalation may lead to international diplomatic intervention, including possible UN Security Council deliberations or multilateral negotiations to ensure safe navigation.
• Increased deployment of naval escorts and convoy systems by major powers could emerge to protect merchant shipping routes.
• Prolonged disruption may accelerate global diversification of energy routes and strategic reserves, reducing dependence on chokepoints like Hormuz.

Way Forward

• Strengthen adherence to UNCLOS principles, ensuring that both coastal states and external powers respect freedom of navigation and transit passage rights.
• Promote multilateral maritime security frameworks involving regional and global stakeholders to ensure safe and uninterrupted shipping lanes.
• Enhance India’s strategic petroleum reserves and energy diversification, reducing vulnerability to chokepoint disruptions.
• Encourage diplomatic de-escalation and confidence-building measures to prevent militarisation of critical global commons.

Prelims Pointers

• UNCLOS (1994) governs maritime zones and navigation rights, including transit passage in international straits.
• Strait of Hormuz is a key global chokepoint handling ~20% of world oil trade.
• Hot pursuit doctrine allows limited interception beyond territorial waters under strict conditions.

Can India move to 100% ethanol blending?

---

Why In News

• Union Minister Nitin Gadkari proposed 100% ethanol blending (E100) and expanded ethanol use for Sustainable Aviation Fuel (SAF), highlighting push toward energy self-reliance and decarbonisation strategy.

Relevance

• GS Paper III (Economy): Energy security, biofuels
• GS Paper III (Environment): Climate mitigation, sustainable fuels
• GS Paper III (Science & Tech): Alternative fuel technologies

Practice Question (Mains)

Q. Critically examine the feasibility of achieving 100% ethanol blending in India. Discuss its economic, environmental, and technological implications. (250 words)

Static Background And Basics

• Ethanol blending programme mixes ethanol with petrol; India achieved E20 rollout of 20% nationwide by April 1,2026, advancing its earlier 2030 target under National Biofuel Policy, 2018, reflecting accelerated energy transition efforts.
• E100 refers to pure ethanol fuel, while most existing vehicles are compatible only up to E20, requiring flex-fuel vehicle (FFV) technology to handle higher blends like E85–E100 efficiently.
• Ethanol production in India is dominated by sugarcane-based feedstock, though policy increasingly promotes second-generation (2G) ethanol from crop residues to address environmental and sustainability concerns.

Technical And Economic Aspects

• Ethanol has 45–55% lower energy density than petrol, implying reduced mileage and higher fuel consumption per kilometre, potentially increasing operational costs for consumers despite blending benefits.
• Adoption of flex-fuel vehicles requires modifications such as corrosion-resistant components, advanced sensors, and optimized engine control units, increasing vehicle costs by approximately ₹3–4 lakh compared to petrol variants.
• Ethanol production costs remain higher than petrol, necessitating government price support and subsidies, raising concerns about long-term fiscal burden and market competitiveness of biofuels.

Linkage With Emission Norms

• Corporate Average Fuel Efficiency (CAFE) norms, introduced in 2017, regulate fleet-wide CO₂ emissions; CAFE III (effective April 2027) mandates nearly 30% stricter emission targets compared to CAFE II standards.
• Ethanol blending can help manufacturers meet CAFE targets, but E20 fuel reduces efficiency by around 6–7%, creating consumer concerns due to increased fuel consumption and running costs.

Strategic Significance

• Enhances energy security by reducing India’s dependence on imported crude oil (around 85%), thereby lowering vulnerability to global price volatility and geopolitical disruptions.
• Supports agricultural diversification and farmer incomes by creating additional demand for feedstock such as sugarcane and crop residues, contributing to rural economic stability.
• Contributes to climate mitigation goals by lowering carbon monoxide and particulate emissions, aligning with India’s commitments under the Paris Agreement and Nationally Determined Contributions (NDCs).

Challenges And Concerns

• Food versus fuel dilemma arises due to reliance on water-intensive sugarcane, potentially impacting food security, water resources, and agricultural sustainability in vulnerable regions.
• Lifecycle emissions of ethanol include land-use changes, fertilizer application, and water consumption, raising questions about its overall environmental benefits compared to fossil fuels.
• Infrastructure limitations in storage, transportation, and distribution networks pose significant barriers to scaling up high-level ethanol blends like E85 and E100 nationwide.
• Increasing use of ethanol for both road transport and aviation fuel (SAF) may create feedstock shortages and supply constraints, affecting long-term sustainability of biofuel strategy.

Ethanol And Aviation Fuel

• Ethanol can be converted into aviation fuel via the Alcohol-To-Jet (ATJ) process, involving dehydration, molecular restructuring, and hydrogenation to produce kerosene-like fuel suitable for aircraft engines.
• ASTM International has approved the ATJ pathway, allowing up to 50% blending in Sustainable Aviation Fuel, ensuring compatibility with existing aviation infrastructure.
• SAF is critical for aviation decarbonisation since alternatives like electric or hydrogen-powered aircraft are not yet commercially viable at scale, making ethanol-derived fuels strategically important.

Way Forward

• Accelerate development and scaling of 2G ethanol technologies based on agricultural residues to reduce dependence on sugarcane and address environmental concerns like stubble burning.
• Promote widespread adoption of flex-fuel vehicles through fiscal incentives, domestic manufacturing, and policy support to reduce costs and improve consumer acceptance.
• Integrate ethanol policy with water management, crop diversification, and sustainability frameworks to prevent ecological stress and ensure long-term viability of biofuel expansion.
• Develop a balanced energy transition strategy, aligning ethanol with green hydrogen, electric mobility, and renewable energy, ensuring diversified and resilient energy systems.

Prelims Pointers

• E20 fuel contains 20% ethanol, while E100 refers to pure ethanol fuel requiring specialized flex-fuel engines for usage.
• CAFE III norms (2027) aim to reduce fleet-wide CO₂ emissions by around 30% compared to earlier standards, influencing fuel and vehicle technology choices.
• ATJ pathway converts ethanol into aviation fuel, with ASTM approval for up to 50% SAF blending in aircraft engines.

Static Background And Basics

• The Nilgiri Tahr (Nilgiritragus hylocrius) is an endemic caprine species of the Western Ghats, found mainly in Tamil Nadu and Kerala, and is the State Animal of Tamil Nadu.
• It inhabits montane grasslands and shola ecosystems at 1,200–2,600 metres altitude, preferring steep rocky cliffs and grassy slopes, making it a key indicator of high-altitude ecosystem health.
• Conservation status: Endangered (IUCN Red List) and protected under Schedule I of Wildlife Protection Act, 1972, ensuring highest level of legal protection.

Key Features Of The Survey

• Synchronised survey method conducted jointly by Tamil Nadu and Kerala ensures simultaneous counting across borders, preventing duplication of animals moving between states.
• The third survey (2026) spans 14 forest divisions, 43 ranges, 124 beats, and 177 survey blocks, significantly expanding coverage compared to earlier surveys.
• Involves ~800 trained frontline staff, enhancing field accuracy and improving reliability of population estimates across the species’ entire habitat range.

Data And Trends

1. First survey (2024): ~1,031 individuals across 140 blocks; Second survey (2025): 1,303 individuals across 177 blocks, indicating improving population trends and better detection methods.
2. Evidence of recolonisation in habitats like Pasumalai and return to previously unoccupied areas reflects successful conservation interventions and habitat restoration efforts.

Technological Innovation

• Introduction of ‘Varudai’ mobile application enables real-time data collection, GPS tracking, and standardised reporting, reducing human error and enhancing monitoring efficiency.
• Integration with web-based platforms allows near real-time aggregation and analysis of field data, improving responsiveness of conservation strategies.

Ecological Significance

• Functions as a flagship and indicator species for montane grassland ecosystems, whose health reflects broader biodiversity stability in the Western Ghats.
• Forms part of the prey base for predators like leopard and occasionally tiger, contributing to trophic balance and ecosystem functioning.
• Coexists with other endemic species like Nilgiri langur and lion-tailed macaque, highlighting importance of biodiversity-rich Western Ghats landscape.

Threats And Challenges

• Habitat loss and fragmentation due to plantations, infrastructure, and hydroelectric projects threaten continuity of high-altitude grasslands.
• Competition with livestock, poaching, and invasive species reduce habitat quality and survival prospects of the species.
• Localised extinction in regions like Karnataka highlands indicates vulnerability and need for landscape-level conservation approach.

Policy And Conservation Significance

• Project Nilgiri Tahr (launched 2023) focuses on population monitoring, habitat restoration, and scientific conservation, aligning with ecosystem-based conservation strategies.
• Synchronised surveys improve data-driven policymaking, enabling targeted interventions like corridor development and habitat protection.
• Participation of institutions like International Union for Conservation of Nature and Wildlife Trust of India ensures scientific rigour and global best practices.

Way Forward

• Strengthen landscape-level conservation across Western Ghats through inter-state coordination and corridor protection, ensuring genetic connectivity and population stability.
• Scale up use of technology-driven monitoring systems like GIS mapping, drones, and AI-based analytics for continuous wildlife tracking.
• Promote community-based conservation models, integrating local livelihoods with biodiversity protection to reduce anthropogenic pressures.
• Prioritise restoration of montane grasslands, which are often undervalued compared to forests but critical for species like Nilgiri Tahr.

Prelims Pointers

• Nilgiri Tahr: Endemic to Western Ghats; IUCN – Endangered; WPA Schedule I.
• Largest population found in Eravikulam National Park (Kerala).
• Project Nilgiri Tahr (2023): Focuses on monitoring and conservation of the species.
