Madurai, 12 Aug — The Madurai Bench of the Madras High Court on Wednesday sought the State government's response to a public interest litigation that urges authorities to prepare and implement a Comprehensive Green Madurai Action Plan and a Madurai Heat Action Plan to restore ecological balance within the city and rejuvenate the Vaigai river system.
Petition calls for restoration of Vaigai river ecosystem and green cover
A Division Bench comprising Justices C.V. Karthikeyan and R. Sakthivel heard the petition filed by C. Selvakumar of Madurai. The petitioner has sought directions to the State and municipal authorities for large-scale measures, including plantation of native tree species along both banks of the Vaigai, restoration of riparian vegetation, protection of wetlands and identification of public lands for creating green corridors.
The petition asserts that climate change, rapid urbanisation and the disappearance of urban forests have weakened natural systems that traditionally moderated local climate, facilitated groundwater recharge and preserved biodiversity. It describes the Vaigai river, its floodplains and adjacent green infrastructure as Madurai's principal ecological lifeline and calls for institutionalised action to arrest further deterioration.
"Environmental protection has now become one of the foremost constitutional obligations of every government," the petition said, emphasising the need for an integrated plan to address rising surface temperatures, shrinking waterbodies and loss of ecological infrastructure.
Key measures sought
- Preparation, approval and implementation of a Comprehensive Green Madurai Action Plan targeting urban tree cover, biodiversity conservation and cooling of heat-prone zones.
- Formulation of a city-specific Madurai Heat Action Plan to mitigate Urban Heat Island effects and protect public health.
- Restoration of the Vaigai river ecosystem through riparian afforestation, wetland protection and reconnection of ecological corridors.
- Identification of suitable government and public lands using GIS mapping for development of urban forests, green parks and green corridors.
The petitioner has urged authorities to prioritise planting of native species, restore degraded riparian vegetation and safeguard ecologically sensitive areas connected to the Vaigai river system. The plea also demands measures for groundwater recharge and improving biodiversity within the urban fabric.
Context and local implications
Madurai, one of India's oldest cities, has historically grown around the Vaigai. The court documents filed in the petition highlight how traditional landscape features — avenue trees, wetlands and floodplains — once moderated the city's climate but have been progressively weakened over recent decades due to unplanned expansion and infrastructure development.
If directed by the court, the proposed action plans would require coordination between multiple agencies, including the State government, Madurai Municipal Corporation and district-level bodies. Implementation would also involve mapping public lands, sourcing native saplings, allocating funds for long-term maintenance and establishing institutional mechanisms to monitor outcomes.
Urban heat, loss of green cover and encroachment of waterbodies have become pressing civic concerns in many Tamil Nadu cities. The petitioner contends that a strategic, legally backed plan for Madurai would not only revive ecological functions but also contribute to public health and sustainable urban development.
The Madurai Bench has posted the matter for further hearing after issuance of notice to the State. No timeline for the government's response was recorded in court on Wednesday.
| Issue | Relief sought |
|---|---|
| Urban green cover | Comprehensive plantation, creation of urban forests and green corridors |
| Vaigai river ecosystem | Riparian restoration, wetland protection, native species planting |
| Heat mitigation | Madurai Heat Action Plan to address Urban Heat Island impacts |
The court's directive for a state response keeps the issue on the judicial agenda and may accelerate administrative attention towards ecological restoration in Madurai. Local environmental groups and residents who have for years expressed concern over shrinking green spaces and receding waterbodies will likely watch the next developments closely.
The matter now awaits the State's official reply and subsequent judicial consideration at the Madurai Bench of the Madras High Court.
