Syllabus: Conservation, environmental pollution and degradation, environmental impact assessment.
Context
- Governments are reducing mandatory green-cover requirements inside industrial estates to promote “ease of doing business.”
- Such relaxations ignore the ecological role of green belts and the limits of their compensatory value.
Why Green Belts Matter?
- Industrial development clears natural vegetation, causing habitat loss and ecological alteration.
- On-site green belts offer local benefits such as dust reduction, microclimate regulation, and noise suppression.
- Evidence shows well-designed green belts reduce TSP by up to 65% and noise by 10–17 decibels.
- However, these benefits remain localised and cannot replace natural ecosystems that offer carbon sequestration, hydrological balance, or biodiversity support.
-
- Limits of Industrial Green Belts
- Industrial plantations are often narrow, mono-specific and degrade over time.
- They do not restore ecological connectivity or resilience.
- They remain mitigative, not restorative, tools.
Why Global Comparisons Are Misleading?
- Green-cover norms abroad reflect different population densities, ecological capacities, and land availability.
- Countries with vast open landscapes can afford lower on-site green ratios.
- Adopting such norms in densely populated, industrially stressed regions like India is ecologically unsound.
Need for a Landscape-Level Approach
- Instead of reducing plot-level green cover, policymakers should balance internal flexibility with external obligations.
- Mandatory off-site greening can include:
- Developing regional green reserves around industrial clusters.
Restoring degraded lands, river basins, and buffers near protected areas.
Integrating industries into green credit or carbon-offset programmes.
- Developing regional green reserves around industrial clusters.
Way Forward
- Combine on-site belts (local healing) with landscape-scale restoration (systemic resilience).
- Industries must become ecological stewards, not mere compliance actors.
- A Nature-Based Solution (NbS) framework ensures that industrial growth and ecosystem regeneration progress together.
