Filling a pond, raising a building on a marsh or discharging untreated waste into a water body can result in demolition orders, heavy compensation and criminal liability. For developers, landowners and citizens alike, wetland law has become a major compliance area.

The legal framework

• Wetlands (Conservation and Management) Rules, 2017, made under the Environment (Protection) Act, 1986, replaced the 2010 Rules and moved management to state wetland authorities. Rule 4 restricts activities such as conversion for non-wetland use, encroachment, dumping of solid waste, discharge of untreated effluents and permanent construction, with limited exceptions.
• Ramsar Convention sites receive international recognition. The East Kolkata Wetlands were designated a Ramsar site in August 2002.
• East Kolkata Wetlands (Conservation and Management) Act, 2006 created the East Kolkata Wetlands Management Authority, which regulates land use in the notified area.
• State laws and municipal laws restrict filling of ponds and water bodies.

The National Green Tribunal

The National Green Tribunal Act, 2010 created a specialised forum for environmental disputes. It hears civil cases involving a substantial question relating to the environment arising under the Water Act, the Air Act, the Environment (Protection) Act, the Forest (Conservation) Act, the Biodiversity Act and related laws, and can award relief and compensation. It applies principles of sustainable development, precaution and polluter pays. The Eastern Zone Bench sits at Kolkata and covers West Bengal. Applications are generally to be filed within six months of the cause of action, extendable by up to sixty days for sufficient cause. Appeals lie to the Supreme Court within ninety days.

Notable Kolkata decisions

In October 2017 the Eastern Zone Bench ordered demolition of a structure called the Temple of Knowledge, built by a trust associated with the Art of Living Foundation by filling wetlands in the East Kolkata Wetlands area, a landmark ruling on illegal construction in a Ramsar site.

Who can approach the NGT

• Citizens, residents and environmental groups affected by pollution or destruction of a water body.
• Project proponents challenging environmental clearance conditions or penalties.
• Landowners challenging adverse orders by authorities.

Practical advice for developers and owners

• Check wetland maps, state records and the East Kolkata Wetlands schedule before purchasing land.
• Obtain the required environmental clearances and consents from the State Pollution Control Board.
• Avoid advance construction when there is a dispute about land classification.

Complainants should file photographs, satellite images, revenue records and authority reports with the application.
