Webinar: Will the Ramsar tag revive Pallikaranai?

Pallikaranai has earned the Ramsar Tag, marking a new milestone for the wetlands in Chennai. But will this tag be enough to stop its destruction?

Stepping into the 76th year of Independence, India now has 75 wetlands that have got the coveted Ramsar site tag. After a gap of 20 years, Tamil Nadu has got the Ramsar tag for 13 wetlands across the State in 2022. This makes Tamil Nadu the State with the highest number of Ramsar sites in India. 

Pallikaranai marshland in Chennai has become the first wetland in the city to get the Ramsar tag.

What is a Ramsar site?

A Ramsar site is a wetland site designated to be of international importance under the Ramsar Convention, also known as “The Convention on Wetlands”, an intergovernmental environmental treaty established in 1971 by UNESCO, which came into force in 1975. 

It provides for national action and international cooperation regarding the conservation of wetlands, and wise sustainable use of their resources. India is one of the contracting parties to Ramsar Convention signed in Iran’s Ramsar in 1971. India signed it on 1 February 1982.

The 14 sites in Tamil Nadu include Point Calimere Wildlife and Bird Sanctuary, Pallikaranai marshland, Karikili bird sanctuary, Pichavaram mangrove forest, Koonthankulam Bird Sanctuary, Gulf of Mannar Marine Biosphere Reserve, Vembannur Wetland Complex, Vellore Bird Sanctuary, Vedanthangal Bird Sanctuary, Udhayamarthandapuram Bird Sanctuary, Chitrangudi Bird Sanctuary, Suchindram Wetland Complex, Vaduvur Bird Sanctuary and Kanjirankulam Bird Sanctuary.

Significance of Ramsar tag for Pallikaranai marshland

The Pallikaranai Marsh is one of the last remaining natural wetlands of Chennai city that has diverse flora and fauna. It is locally known by the generic Tamil name ‘kazhuveli’ which means a flood plain or waterlogged area. The marsh contains several rare or endangered and threatened species and acts as a forage and breeding ground for thousands of migratory birds from various places within and outside the country.

However, over the period of years, the marsh has shrunk from 2,650 hectares to a mere 700-odd hectares. Encroachments by both government and private sectors, garbage dumping, the release of untreated sewage and urbanisation are top among the many reasons behind the degradation of the marshland. This has happened despite the wetland being declared as a ‘protected zone’ under Tamil Nadu Forest Act. While the remaining 700 hectares is said to be divided into four parts, only 370 hectares have been declared as Ramsar site.

How will this Ramsar tag for a part of the marshland help in retrieving the last remaining wetland of Chennai? What are the challenges ahead in retrieval and conservation of the marsh? 

The government has said that a health card containing the hydrological and ecological parameters of the wetland would first be prepared followed by an integrated management plan. What kind of scientific approaches would help in retrieval? 

Citizen Matters brings together a panel of experts to examine these questions and more.

Study shows TNPCB ill-equipped to monitor the environmental impact of pollution

The scientific team of TNPCB is working at half its strength, affecting the Board's ability to carry out inspections in Chennai and other parts of the State.

The Central Pollution Control Board and the State Pollution Control Boards are the primary custodians for preventing and controlling all forms of pollution in our country. Despite their significant role in environmental protection, the public is mostly unaware of the functions of these regulatory bodies, due to insufficient research. Therefore, we at Citizen consumer & civic Action Group (CAG) have attempted to understand the functions of the Tamil Nadu Pollution Control Board (TNPCB), through a study titled โ€˜The Tamil Nadu Pollution Control Board in Retrospect: An Examination of Selected Parameters from 2017 to 2022.โ€™ Read more: Fisherfolk lament as environmental…

Why the national programme for clean air failed a gasping Mumbai

Mumbai has seen an alarming decline in air quality. A look at the limited impact of the National Clean Air Programme on mitigating pollution.

October 2023 was a shocker for Mumbai. The coastal city has historically recorded lower AQI levels as compared to Delhi, which is notorious for its poor air quality. But the tables turned in October 2023, with AQI in Mumbai reaching dangerously high levels of up to 300, surpassing Delhi for several days. This led to a slew of respiratory ailments, more so among the vulnerable populations. PM2.5 levels have, in fact, seen a consistent increase in Mumbai over the past three years. Dr Jui Mandke, a paediatric surgeon practising in Mumbai, says, โ€œIn October 2023, we encountered the maximum number…
