IAS Mains Answer Writing-21 April 2026

1. The fragile Himalayan ecosystem is increasingly threatened by anthropogenic pressures. Analyze the causes of environmental degradation in the region and critically evaluate the role of government policies and community initiatives in achieving a balance between ecological conservation and economic development.

Introduction

• The Indian Himalayan Region, covering about 16–18% of India’s geographical area, is a part of global biodiversity hotspots identified by Conservation International and serves as the source of major river systems such as the Ganga, Brahmaputra, and Indus.

• However, due to its young fold mountains, tectonic instability, and fragile ecology, the region is highly vulnerable to anthropogenic pressures, leading to accelerated environmental degradation.

Anthropogenic Causes of Environmental Degradation

• Unplanned Infrastructure and Urbanisation:

  • Rapid expansion of roads, tunnels, and hydropower projects destabilises slopes.

  • Joshimath subsidence (2023) reflects consequences of unscientific construction.

• Deforestation and Land Use Change:

  • Forest loss due to agriculture, tourism, and construction.

  • Significant forest loss has been recorded in districts like Tehri Garhwal due to infrastructure and development activities.

  • Leads to soil erosion and landslides.

• Tourism Pressure:

  • Mass tourism exceeding carrying capacity: ~5 million visitors in Char Dham (2025).

  • Causes waste accumulation, water stress, and habitat destruction.

• Hydropower and River Modification:

  • Alters natural flow regimes and sediment transport.

  • Threatens aquatic biodiversity and increases disaster risks.

• Climate Change Amplified by Human Activity:

  • Himalayan glaciers retreating rapidly (e.g., Gangotri shrinking ~10-20 m/year).

  • Glacier mass loss in the Hindu Kush Himalaya has accelerated significantly in recent decades.

• Increased Disaster Vulnerability:

  • The Himalayan region is highly landslide-prone due to its young and fragile geology.

  • There has been a sharp rise in extreme events such as floods, landslides, and cloudbursts in the last decade.

  • Frequency and intensity of landslides in Uttarakhand have increased significantly since the 2000s.

Government Measures

• Policy Frameworks:

  • National Mission for Sustaining Himalayan Ecosystem (NMSHE) under NAPCC

    • Focus: glacier monitoring, biodiversity conservation, sustainable livelihoods.

  • Eco-Sensitive Zones (ESZ), Environmental Impact Assessment (EIA).

• Conservation and Climate Initiatives:

  • SECURE Himalaya Project (UNDP-supported).

  • National Mission on Himalayan Studies – promotes research.

  • Green India Mission – afforestation efforts.

• Disaster Risk Reduction:

  • Early warning systems, NDMA guidelines.

  • Use of remote sensing and AI-based monitoring suggested.

• Sustainable Tourism Policies: Carrying capacity-based tourism and eco-tourism promotion.

• Limitations:

  • Weak EIA enforcement and frequent dilution.

  • Project-centric approach (roads, dams) over ecological concerns.

  • Lack of region-specific planning and inter-state coordination.

Community Initiatives

• Traditional Ecological Knowledge: Sustainable agriculture, water harvesting, sacred groves.

• Grassroots Movements: Chipko Movement – landmark forest conservation effort.

• Community-Based Eco-Tourism: Sikkim, Ladakh models promoting low-impact tourism.

• Local Disaster Management Practices: Indigenous coping strategies and resilience building.

• Evaluation:

  • Strengths: Context-specific, sustainable, participatory.

  • Challenges: Limited scalability, funding constraints, weak institutional integration.

Way Forward

• Carrying Capacity-Based Development (tourism, infrastructure).

• Separate Himalayan EIA framework.

• Nature-based solutions (NbS) + modern technology integration.

• Decentralised governance & community empowerment.

• Promote climate-resilient infrastructure and livelihood diversification.

Conclusion

• The Himalayan crisis reflects a classic development–ecology conflict.

• Achieving sustainable balance requires a synergistic approach, integrating scientific policy frameworks with community-led conservation to ensure both ecological integrity and economic development.

2. The Western Ghats are central to India’s ecological security and sustainable development. Analyse their ecological and economic significance, and critically evaluate the effectiveness of conservation strategies in addressing emerging threats.

Introduction

• The Western Ghats, a ~1600 km long mountain chain across six states, is one of the world’s eight “hottest biodiversity hotspots” and a UNESCO World Heritage Site.

• It harbours ~7,400 species, including 325 globally threatened species, making it central to India’s ecological security.

Ecological Significance

• Exceptional Biodiversity and Endemism:

  • The Western Ghats, along with Sri Lanka, are recognized by Conservation International as one of the world’s eight “hottest hotspots” of biodiversity due to high endemism and significant habitat loss.

  • High endemism:

    • Amphibians: ~75–80%

    • Reptiles: ~50–60% endemic

    • Plants (overall): ~30–40% endemic

  • Hosts 325 globally threatened species (IUCN Red List).

• Climate Regulation and Monsoon Dynamics:

  • Acts as a barrier to southwest monsoon winds, influencing rainfall patterns.

  • Supports climate stability and acts as a major carbon sink.

• Water Security:

  • Origin of major rivers: Godavari, Krishna, Kaveri.

  • Provides water to ~245 million people.

• Ecosystem Services:

  • Soil conservation, flood moderation, nutrient cycling.

  • Maintains ecological balance in peninsular India.

Economic Significance

• Agriculture and Plantation Economy:

  • Major producer of tea, coffee, rubber, spices (cardamom, pepper).

  • Supports export-oriented agriculture.

• Energy Security: Numerous hydropower projects (dams like Koyna, Idukki, Sharavathi) contribute to electricity generation.

• Livelihoods:Supports ~50 million people, including tribal communities.

• Tourism Economy: Eco-tourism and hill stations generate employment and revenue.

Emerging Threats

• Deforestation and Land Use Change:

  • Expansion of plantations (tea, coffee, rubber) replacing natural forests.

  • Increasing urbanisation and tourism infrastructure fragment habitats.

  • Leads to loss of biodiversity and disruption of wildlife corridors.

• Developmental Pressures:

  • Mining (especially Goa), infrastructure, dams.

  • Wildlife roadkills: 6,500+ animals killed (1997–2023).

• Climate Change:

  • Increased temperature and erratic monsoon patterns.

  • Higher frequency of extreme rainfall, floods, and landslides (e.g., Kerala floods).

  • Threatens endemic species sensitive to microclimatic changes.

• Biodiversity Loss and Invasive Species:

  • Spread of invasive species like Lantana camara.

  • Replacement of native flora with monoculture plantations.

  • Increasing species extinction risks, especially amphibians.

  • Decline in flagship species like lion-tailed macaque.

• International Concern: Categorised as “Significant Concern” by IUCN World Heritage Outlook (2025).

• Other Issues: Sand mining, invasive species, human-wildlife conflict.

Conservation Strategies

• Gadgil Committee (WGEEP, 2011): Recommended complete ESZ classification with zonation (ESZ 1, 2, 3) and strict regulation.

  • Ecologically sound

  • Politically resisted, seen as anti-development

• Kasturirangan Committee (2013): Suggested ~37% area as ESZ with a “balance approach”.

  • More practical

  • Criticised for dilution of ecological concerns

• Legal and Institutional Measures:

  • Environment Protection Act, ESZ notifications.

  • Protected Areas: Biosphere reserves (e.g., Nilgiri Biosphere Reserve), national parks (e.g., Silent Valley National Park).

  • Use of satellite-based forest monitoring (e.g., Karnataka) improving fire control (2026 success rates ~90–95%).

• Community and Civil Society Initiatives:

  • Sacred groves (Devrai in Maharashtra, Kavu in Kerala), participatory forest management.

  • Grassroots movements (Save Western Ghats Movement).

Critical Assessment

• Strengths:

  • Global recognition (UNESCO, IUCN).

  • Scientific committees and policy frameworks exist.

  • Increasing use of technology and community participation.

• Limitations:

  • Implementation deficit and weak enforcement.

  • Conflict between economic development vs ecological sustainability.

  • Fragmented governance across states.

  • Insufficient integration of local communities in decision-making.

Way Forward

• Landscape-level planning and cumulative impact assessment.

• Carrying capacity-based tourism and development.

• Strengthen community-led conservation (bottom-up approach).

• Promote nature-based solutions (NbS) and climate resilience.

• Harmonise Gadgil’s ecological vision with Kasturirangan’s practicality.

Conclusion

• The Western Ghats represent a classic case of ecology–development dilemma.

• Ensuring their sustainability requires a science-based, participatory, and region-specific approach, integrating conservation with inclusive economic growth for long-term ecological security.
