GS Paper III – Cropping Patterns, Sustainable Agriculture, Environmental Pollution
Why in News?
- In 2025, India overtook China to become the world’s largest rice producer.
- India now supplies ~40% of global rice exports, crossing 20 million metric tonnes.
- This achievement has revived debate on water stress, ecological sustainability, climate change, and virtual water exports, especially from north-western India.
Background: Rice in India’s Agrarian System
- Rice has been central to India’s food security strategy since the Green Revolution.
- Assured procurement under MSP, free/subsidised electricity, and irrigation created a rice–wheat monoculture in Punjab and Haryana.
- What was once a food security imperative has now become an ecological liability.
Facts Regarding Rice
|
Agro-Climatic Requirements
- Kharif crop requiring:
- Temperature: >25°C
- Rainfall: >100 cm
- High humidity
- Thrives in water-retentive soils, making it suitable for monsoon regions but problematic in semi-arid zones.
Rice Cultivation Practices
1. Traditional Transplanted Paddy
- Seedlings grown in nurseries and transplanted.
- Requires continuous flooding.
- Consumes 25–27 irrigations per season.
- Maximises yield but is resource-intensive.
2. Direct Seeded Rice (DSR)
- Seeds drilled directly into fields.
- Reduces:
- Water use
- Labour requirement
- Energy consumption
- Crucial for water-stressed regions, but requires:
- Weed control
- Proper soil moisture management
Government Initiatives for Sustainability
Water Management
- Promotion of DSR, micro-irrigation under PMKSY.
- State incentives (e.g., Haryana crop diversification schemes).
Climate-Resilient Agriculture
- ICAR’s NICRA programme for drought-, heat- and salinity-tolerant rice.
Nutritional Security
- Fortified rice under NFSA and PM-POSHAN to tackle anaemia.
Climate Action
- Alternate Wetting and Drying (AWD) to reduce methane emissions.
- Rice practices integrated into India’s climate mitigation strategy.
Major Concerns Associated with Rice Cultivation
1. Groundwater Depletion
- 1 kg rice = 3,000–4,000 litres of water.
- In Punjab–Haryana:
- Water table fell from ~30 feet to 80–200 feet.
- Extraction exceeds recharge by 35–57% annually.
- Represents inter-generational ecological injustice, burdening future generations.
2. Environmental Degradation

Why in News?
India’s cities are increasingly experiencing extreme heat, intensified by the Urban Heat Island (UHI) effect. Amid this warming, urban birds are emerging as early victims, with rescue centres reporting rising cases of dehydration, collapse, and mortality during heatwaves. Their decline signals a deeper ecological crisis linked to climate change and unsustainable urbanisation
India’s Growing Urban Heat Crisis
Urban India is warming rapidly. Built-up neighbourhoods now experience hotter days and warmer nights, making cities resemble heat chambers. As temperatures cross 45°C in cities like Delhi and Ahmedabad, the most immediate ecological impacts are visible among birds, whose absence has made many urban mornings quieter.
Urban Heat Island (UHI): Meaning and Causes
An Urban Heat Island forms when:
- Concrete, asphalt, and buildings absorb heat during the day
- Heat is released slowly at night, preventing cooling
Key Causes in Indian Cities
- Dense construction
- Loss of vegetation
- Vehicular emissions
- Heat from air conditioners
Indian Context
- UHI intensity ranges from 2–10°C
- Peak surface hotspots are 6–8°C hotter
- Cities affected: Delhi, Ahmedabad, Bengaluru, Mumbai
Why Birds Are the First Casualties
Birds are especially vulnerable because:
- They are small endotherms
- They have high metabolic rates
- They depend on shade, water, and insects
Reduced tree cover and water availability during heatwaves severely limit their ability to regulate body temperature.
Scientific Evidence of Bird Decline
Multiple studies confirm the link between heat and bird loss:
- Bengaluru Study (2025)
Higher surface temperatures correlated with lower bird abundance - Western Ghats Study (2022)
Rising temperatures and shrinking green cover pushed forest-dependent birds out first - China Multi-City Study (2023)
Stronger urban heat associated with reduced species richness and functional diversity
These findings show that urban warming is reshaping bird communities.
Physiological and Behavioural Stress in Birds
Physiological Impacts
- Dehydration
- Hyperthermia
- Oxidative stress
Behavioural Changes
- Activity shifts to dawn and dusk
- Nest abandonment on exposed branches
- Shortened breeding seasons
- Reduced hatching success and chick survival
Prolonged exposure can cause population decline.
Rescue Data and Ground-Level Evidence
Rescue reports strongly support scientific findings:
- Gujarat Heatwave (2022): Reuters, Al Jazeera reported mass bird rescues
- Wildlife SOS and Charity Bird Hospital recorded sharp increases in heat-related admissions
- Mumbai & Bengaluru (2024): Spikes in kite, myna, and pigeon rescues
- Ahmedabad (May 2025): Jivdaya Charitable Trust treated ~3,800 birds
Key Observation
Areas with trees recorded fewer rescues, while treeless commercial zones saw more collapsed birds.
Urban Heat and Wider Ecosystem Disruption
Urban heat interacts with:
- Air pollution
- Light pollution
- Habitat fragmentation
Ecosystem Impacts
- Reduced insect populations → food loss for birds
- Faster evaporation of ponds → amphibian decline
- Overheated roosts → bats abandon habitats
This leads to biotic homogenisation, where only a few heat-tolerant species survive.
Urban Planning Gaps
Urban heat mitigation often focuses on:
- Reflective roofs
- Pavements
- Ventilation corridors
However, ecological cooling is largely ignored, despite evidence that:
- Tree-rich areas are 1–3°C cooler
- Green spaces like Delhi Ridge and Lodhi Gardens support higher bird diversity and cooler nights
Urban ecologists argue that climate adaptation and biodiversity conservation are inseparable.
Nature-Based Cooling and Biodiversity Solutions
- Increase Urban Canopy
- Native trees like neem, jamun, banyan
- Restore Ponds and Wetlands
- Act as heat sinks and drinking sources
- Green Infrastructure
- Cool roofs, vertical gardens, rooftop vegetation
- Urban Biodiversity Corridors
- Connect parks and water bodies
- Citizen Action
- Water bowls, tree protection, local planting
Policy Linkages and SDG Alignment
- National Mission on Sustainable Habitat
- SDG 11 – Sustainable Cities and Communities
- SDG 15 – Life on Land
Nature-based solutions provide climate resilience and biodiversity protection together.
Conclusion
Birds are the most visible indicators of ecological stress in cities. Their silence is a warning that urban growth without ecological sensitivity is unsustainable. Integrating biodiversity into urban planning—through trees, wetlands, and green corridors—offers a cost-effective, inclusive, and climate-resilient solution. Saving birds from urban heat is ultimately about saving the livability and sustainability of Indian cities.
