Transboundary Pollution / Regional Cooperation

What is Transboundary Pollution / Regional Cooperation?

Transboundary pollution refers to pollution that originates in one geographical or administrative jurisdiction (e.g., a state or country) but causes adverse effects in another. Addressing such pollution necessitates regional cooperationcoordinated efforts among affected jurisdictions due to its cross-border nature.

Historical Background

The concept gained prominence with the understanding that environmental problems like acid rain, ozone depletion, and river pollution do not respect political boundaries. In India, the issue of air pollution in Delhi-NCR has particularly highlighted the need for inter-state cooperation since the early 2000s.

Key Points

7 points
  • 1.

    Nature: Pollution (air, water, soil) that crosses state or national borders, making it difficult for a single entity to control.

  • 2.

    Challenges: Includes issues of jurisdiction, blame-game politics, lack of coordinated policy implementation, differing economic priorities, and enforcement difficulties.

  • 3.

    Need for Cooperation: Essential for effective mitigation as sources and impacts are geographically dispersed.

  • 4.

    Mechanisms: Can involve inter-state agreements, joint task forces, shared monitoring networks, harmonized policies and regulations, and resource sharing.

  • 5.

    Examples: Air pollution in Delhi-NCR (involving Delhi, Haryana, UP, Punjab), river pollution (e.g., Ganga, Yamuna), smog in Southeast Asia from forest fires.

  • 6.

    Key Stakeholders: Central government, state governments, local bodies, pollution control boards, research institutions, and civil society organizations.

  • 7.

    Policy Tools: Graded Response Action Plan (GRAP) for Delhi-NCR is an example of a regional, coordinated action plan.

Graded Response Action Plan (GRAP) Implementation Process

This flowchart illustrates the operational mechanism of the Graded Response Action Plan (GRAP) in Delhi-NCR, a key regional cooperation strategy to combat severe air pollution episodes based on real-time air quality levels.

  1. 1.Continuous Monitoring of Air Quality Index (AQI) by CAQM/CPCB
  2. 2.AQI Level Exceeds Thresholds?
  3. 3.CAQM Activates GRAP Stage (I, II, III, or IV - based on severity)
  4. 4.Coordinated Actions by Delhi & NCR States (Haryana, UP, Rajasthan)
  5. 5.Examples of Actions: Ban Construction, Restrict Vehicles (Odd-Even), Close Industries, Ban Firecrackers
  6. 6.Air Quality Improves?
  7. 7.CAQM Deactivates/Downgrades GRAP Stage

Recent Developments

4 developments
→

Increased judicial intervention by the Supreme Court and National Green Tribunal (NGT), directing states in the NCR to cooperate on air pollution.

→

Formation of the Commission for Air Quality Management (CAQM) in NCR and Adjoining Areas in 2020 to coordinate efforts among states.

→

Implementation of GRAP across Delhi-NCR, requiring coordinated actions from multiple states based on air quality levels.

→

Focus on regional solutions for stubble burning and industrial emissions in the NCR.
