Role of green belt development purpose and advantage
What a green belt is, why it is required and where the law uses it
Scope: Green belts as an anti-pollution and land-use tool: purpose, advantages and the legal routes through which a green belt is required.
In one minute
A green belt is a strip or zone of trees and plants that is planted and kept on purpose. It sits around an industry, between an industrial area and homes, or around a growing city.
It traps dust, softens noise and separates land uses. A consent condition, court order or town plan usually requires it. It supports pollution control but does not replace it.
Exam focus
- Frequency: No data
- Usually asked as: No data
Legal provision
- Environment (Protection) Act, 1986, section 5: the Central Government may direct the closure, prohibition or regulation of any industry, operation or process.
- Water Act, 1974, section 25: previous consent of the State Board for an industry that discharges effluent.
- Air Act, 1981, section 21: previous consent for an industrial plant in an air pollution control area.
- Twelfth Schedule (Article 243W): municipal functions include urban planning (item 1), regulation of land-use (item 2) and urban forestry, protection of the environment and promotion of ecological aspects (item 8).
- Constitution, Articles 48A and 51A(g): the State's directive and the citizen's duty to protect the environment, the broad basis for such measures.
Meaning and definition
A green belt is a deliberately planted and maintained zone of trees and plants, required as a planning or regulatory condition. It differs from a park or a tree-planting drive because the law or an authority requires it for a stated purpose.
Detailed explanation
Purpose
The purpose is to reduce the effect of an industry or a city on its neighbours. A belt of dense planting around an industrial unit can catch dust and soften the noise reaching nearby homes. Between an industrial and a residential zone, it keeps the two apart. Around a city, a ring of restricted land can check unplanned sprawl.
Advantages
- It works as a natural filter for dust and some gases.
- It lowers the noise that reaches the neighbourhood.
- It separates incompatible land uses.
- It can give some habitat for wildlife in built-up areas.
How the law requires a green belt
- Consent or clearance conditions. A State Pollution Control Board may require a green belt when it gives consent or a no-objection certificate.
- Court orders. In the Taj Trapezium case, NEERI recommended a Green Belt Development Plan around the Taj, and the Court monitored it.
- Remedial orders. In the Bichhri case, NEERI suggested that the contaminated area be developed as a green belt at the cost of the polluting company.
- Town planning. Municipal planning of land-use and urban forestry can set aside green zones.
Example. A cement unit seeks clearance near a town. The authority allows it on condition that the unit plants and keeps a dense belt of trees along the boundary facing the town.
Common mistakes
- Treating a green belt as a public park. It exists for a regulatory or planning purpose.
- Treating it as a replacement for effluent or emission control. It is an added measure.
- Quoting a fixed percentage of land from memory. Each consent or clearance sets its own requirement.
Leading case laws
- M.C. Mehta v. Union of India (Taj Trapezium Case)
Facts. Industrial emissions were damaging the Taj Mahal.
Principle. The green belt recommended by NEERI was set up around the Taj under the Court's monitoring.
Why it matters. A court enforced a green belt.
- Indian Council for Enviro-Legal Action v. Union of India
Facts. Toxic waste from chemical plants at Bichhri polluted wells and soil.
Principle. NEERI suggested that the contaminated area be developed as a green belt at the polluter's expense.
Why it matters. It links green belts with the polluter pays idea.
