How Russia-Ukraine Conflict and Rice Trade Disruptions Worsened Delhi's Air Quality

Introduction

The intricate web of global geopolitics has far-reaching consequences, often in unexpected domains. The Russia-Ukraine conflict, combined with disruptions in the global rice trade, has indirectly worsened air quality in Delhi-NCR during the winter of 2024.

By altering cropping patterns across South Asia, particularly in Punjab regions of both India and Pakistan, these events have intensified crop residue burning—a significant contributor to Delhi’s winter smog.

This blog unravels the chain of events connecting international sanctions, trade disruptions, and local environmental challenges, highlighting the need for a unified regional response to address air quality issues.

The Global Ripple Effect: From Geopolitics to Agriculture

1. The Russia-Ukraine Conflict’s Role in Food Commodity Trade

• Impact on Fertilizer Supply: Russia, the largest exporter of fertilizers, faced export restrictions due to sanctions, causing a global price surge. Indian farmers, already burdened by rising input costs, reverted to traditional practices like stubble burning to cut expenses.

• Food Inflation and Rice Export Ban: India imposed a rice export ban in 2023 to curb domestic inflation. Although lifted recently, the ban had already shifted rice production dynamics, compelling neighboring Pakistan to increase exports.

Crop Residue Burning: A Persistent Problem

2. Mechanized Harvesting and Tight Sowing Windows

Mechanized harvesters leave behind stubble that is labor-intensive to clear. With a narrow window to sow Rabi crops, burning becomes the easiest option for farmers in Punjab and Haryana.

3. Long Basmati Stalks and Limited Alternatives

The popular Pusa 1121 Basmati variety leaves longer stalks that are unsuitable as animal fodder due to high silica content, forcing farmers to burn the residue.

The Punjab Connection: India and Pakistan

4. India’s Green Revolution Legacy

• Groundwater depletion and delayed monsoons complicate the sowing schedule for rice, increasing reliance on stubble burning.
• Fertilizer-intensive farming practices, exacerbated by high costs, perpetuate the cycle of burning.

5. Pakistan’s Role in the Cross-Border Impact

• Pakistan’s Punjab increased rice exports during India’s export ban, leading to a rise in stubble burning. Weak enforcement of anti-burning laws allowed the smoke to drift eastward, contributing to Delhi’s pollution woes.

The Funnel Effect: Geography Meets Pollution

Delhi’s unique geography amplifies its vulnerability:

• Wind Patterns: Seasonal winds funnel pollution from Punjab regions into Delhi through the Potwar Plateau and Aravalli Ridge.
• Transboundary Pollution: Smog from Pakistan mingled with local emissions, pushing Delhi’s Air Quality Index (AQI) to hazardous levels.

Mitigation Efforts and Challenges

6. India’s Government Initiatives

• Crop Residue Management Scheme: Promotes machines that mix stubble into the soil, reducing the need for burning.
• Agri-Infrastructure Fund: Encourages recycling crop residue into energy and other products.

7. The Reality on the Ground

• Most subsidies and equipment benefit large farmers, leaving small and medium farmers reliant on traditional practices.
• Despite awareness campaigns, farmers lack affordable alternatives to manage residue effectively.

8. Regional and Global Interventions

• The World Bank’s Air Quality Management Program in South Asia aims to address transboundary pollution.
• Stronger implementation and cooperative frameworks are needed to combat the shared environmental crisis.

The Way Forward: A Unified Approach

The interconnection of global geopolitics, trade disruptions, and local agricultural practices underscores the need for:

1. Regional Collaboration: Establish a South Asian air quality alliance for coordinated action.
2. Incentive-Driven Solutions: Provide affordable, accessible residue management options for small farmers.
3. Climate-Resilient Agriculture: Promote less water-intensive crops to reduce dependency on rice farming in Punjab.

Conclusion

The Russia-Ukraine conflict’s ripple effects on the global rice trade have illuminated the fragile link between international events and local environmental crises.

Delhi’s air quality deterioration in 2024 serves as a stark reminder of the interconnected challenges we face in an increasingly globalized world. Addressing this requires not only localized solutions but also a robust regional and global framework for sustainable practices and clean air initiatives.

Let us act collectively to turn this global challenge into an opportunity for a cleaner and healthier future.

FAQs

Q1: How does stubble burning impact air quality in Delhi?

A: Burning releases particulate matter and toxic gases, worsening smog and respiratory issues.

Q2: What role did the Russia-Ukraine war play in Delhi’s pollution?

A: Sanctions on Russia disrupted fertilizer supplies, increasing costs and stubble burning practices in South Asia.

Q3: What are the solutions to stubble burning?

A: Promoting residue management machines, crop diversification, and regional air quality management frameworks.

This comprehensive analysis underscores the importance of global-local synergies in addressing air pollution challenges. Share your thoughts and join the conversation on sustainable solutions for cleaner air.
