PART 1 PODCAST
We jump aboard and firstly meet the co-curators of Sundarban Tramjatra: Kolkata-based filmmaker and activist Mahadeb Shi, former Melbourne tram conductor and environmental educator Roberto D’Andrea, and myself, Mick Douglas, artist, curator, and Assoc. Professor at RMIT University.
The panel includes four eminent Kolkatans.
Abhijeet Chatterjee is a Scientist at the Bose Institute and Advisor to the National Clean Air Programme. He succinctly explains that a 1% increase in carbon particulate in the Sundarban atmosphere that is generated in nearby Kolkata reduces the photosynthesis activity of Sundarban mangroves by an exponential 15%, producing death of plant cells, and hence significantly reduces the capacity of mangroves to sequester carbon.
Bhargav Maitra, Transport Expert of IIT Kharagpur, argues that sustainable urban transport needs to focus on connectivity services to meets people’s needs, rather than fixate on the illusion that moving ever increasingly more cars will ever solve the challenges of congestion.
Ashoke Vishwanathan, filmaker and scholar, reminds us of the role that the tram has played in the Bengali films of Satajit Ray and Mirinal Sen, and how we urgently need more art that enters the public psyche and shapes cultural awareness of our pressing climate problems and imaginative responses.
Jawhar Sircar, a former MP of India & Retired Public Servant, describes how over the last 7-9 years, the entire legislative apparatus of environmental protection in India is being destroyed, one at a time. He advocates social media campaigns, and use of orders of the courts as necessary resistance.
PART 2 PODCAST
This second part of the Citizens Assembly of March 2025 brings into conversation a panel of five experts.
Mahalaya Chatterjee is a Professor of transport economics at Calcutta University. She proposes that public transport survives when it is regular, cost effective and efficient, but sadly Kolkata tramways has been victim of neglect. Kolkata is dependant on ecologically vulnerable areas around it — most importantly the Sundarbans, which needs alternative livelihood opportunities for people to care for the inter-tidal mangrove forest ecology.
Tathagata Chatterji is a Professor of Urban Management at XIM University, who reminds us how the 1966 released BC Roy’s Basic Development Plan for the Calcutta Metropolitan District was a comprehensive urban planning strategy integrating linkages of Kolkata and its surrounding region. He argues that since the 1990’s development decisions have been unplanned, and greater Kolkata sorely needs an integrated transit-oriented urban development plan, which he thinks will take civil society groups to articulate how to shape the type of city we have to the city we need.
Alok Jain is Director of Trans-consult, and former CEO of transport systems in Hong Kong, where 90percent of daily travel is via public transport. He says Kolkata could have an effective, sustainable and cared for tramways, in which half a million daily journeys through Kolkata by tramways would make a significant impact on decarbonising transport. He boldly proposes to give the tramways to him, and he will run it at zero cost to government.
Pradip Kakkar, Environment Activist of the group PUBLIC, a litigant against the Government of West Bengal’s neglect of Kolkata Tramways, who believes in people getting involved in the problems around them. He is concerned for the future climate resilience of Kolkata: its citizenry is aging with 11% over 60s and increasing, have high literacy, have lowest fertility, and the 20-29 age group are outwardly migration for lack of opportunity, whilst 7,000 vehicles are registered per month.
Kunal Sarkar, a Cardiac Surgeon and well known debater, gives a birds-eye overview of Kolkata’s present situation of what he calls ‘socio-economic drift’. With population in decline, increasingly European lifestyle behaviour, and increasing income in India, the geo-political forces are reversing Indian social conscious prioritisation of climate issues to meet short term ends.
PART 3 PODCAST
In the third part of the Citizens Assembly journey, seven highly respected speakers bring about a rich exchange of knowledge and experience, and aspirations for the Sundarban and Kolkata and their human and non-human species.
Tuhin Ghosh, Professor Oceanographic Studies at Jadavpur University summarises the ecosystem relation of Kolkata and Sundarban as a transportation back and forth: Kolkata receives the good from Sundarban and delivers the bad to the Sundarban. The 16 million people of greater Kolkata are producing pollution that is transported to Sundarban, including waste from six municipalities into the river system flowing to Sundarban. The Sundarban delivers ecosystem services to Kolkata, including the cyclone buffer to Kolkata, but also fish, crabs, honey and vegetables. Cutting down of mangroves needs to stop, but people of the Sundarban will need support for alternative livelihoods, and will likely be seeking compensation in the near future for loss and damages.
Gautam Ghosh, celebrity Film Director, makes films that he says address an urge or purpose. His most recent film ‘Parikrama’ is set amongst the environmental and human displacement in India’s Narmada Valley. He proposes that no longer in an Age of Belief or Age of Enlightenment, humanity is now in an Age of Greed. Whilst todays policy-makers’ focus on economy does not care for this small blue planet, he urges art to cultivate a consciousness of understanding the root causes of materialistic greed and the quick profit.
Pradeep Vyas is a Former Director of the Sundarban Biosphere Reserve, who sees the tram as a symbol of people standing together for environmental sustainability. The Sundarban is subsiding at 2 to 3 times global average of sea level rise, and as an early victim of climate change, it’s ecological refugees would place further pressure on Kolkata. He shares a raft of revealing data: The Sundarban comprises approximately 36 mangrove species and 80 mangrove associate species, which according to a 2015 study, provides US$12.8 billion ecosystem services every year, which is 50,000 Rupees per hectare. 13% of the Sundarban’s ecosystems services are tangible, but 87% are intangible and need to be given importance. He proposes a 1% kind of Sundarban tax that acknowledges that people protect the Sundarban, and need to be valued and supported to continue that protection.
Ritwick Dutta is an Environment Lawyer, Founder of LIFE (Legal Initiative for Forest and Environment). He outlines how loss and damages has been formalised in the UN led International Panel of Climate Change (IPCC) process, with the World Bank taking charge of it for first 4 years. However unless the Nation State takes an obligation in climate change there is no capacity for individuals or organisations to go before the court, so efforts are underway to change institutional mechanisms enabling people to take to the court. The IPCC’s 2019 India's Coastal Regulation Zone (CRZ) Notification designates the entire Sundarban area a CVCA (Critically Vulnerable Coastal Area). He says serious gaps in governance of the Sundarban must be addressed: the management of the Biosphere Reserve and Tiger Reserves must be located and undertaken on ground, not remotely from Kolkata and Canning, and coastal management authorities must be cease to operate in violation of the 2019 Coastal Regulation Zone (CRZ) Notification.
Krishna Ray, Associate Professor of Botany at West Bengal State University, is well aware of how Sundarban Mangroves are the saviour of Kolkata from cyclone and water surges. She speaks to the limits of planted mangroves of few species compared to naturally replicated regeneration, and is leading a program of mangrove planting on an ‘ecological restoration principle’ with minimal human intervention so that after 2-3 years these areas become self-sustaining with a naturally regenerated diversity of other species as exists in surviving areas. Given it is unclear when natural regeneration will kick-in by itself and thus create protection, she argues there is a necessary urgent role for mangrove planting.
Punyasloke Bhadury is Professor of Biological Sciences at Jadavpur University. He studies how the Sundarban absorbs disturbances and pollutants from surrounding areas of West Bengal and beyond, to make it the worlds largest plastics dump. Comparison between Sundarban mangroves and other global mangroves ecosystems reveal that the sediments and water includes many special types of bacteria that keep unique ecosystem alive, but this is rapidly changing as barrages are broken and higher salinity causes changes. He argues for local solutions for local problems that address global problems, such as an ecological restoration program in the Sundarban that is bringing back oysters which play a key role in reducing erosion risk.
Subhas Acharyan is a Member of the Sundarban Development Board, who puts it simply: If you want to save Kolkata you must save Sundarban. Stopping the flow of rivers is having damaging impacting on the downstream ecology of the Sundarban. He says that people can plant mangroves, but cannot create forest in its diversity, so remaining forest must be protected. Since 1951 the human population in the Indian Sundarban has increased from 1.1million to a present estimated 5 million, despite decreasing land area, and there is an emerging drinking water crisis across the islands.
PART 4 PODCAST
Now on this last leg of the Citizens Assembly journey, here is a heart lifting musical offering recorded live at the ICCR auditorium in Kolkata. First up is Bijoysurodeep Sil and Ektara Desi’s performance of their 2024 released song celebrating tramways, Tram er gaan, joined in chorus by the former Melbourne tram conductor Roberto D’Andrea. And lastly, long time Tramjatra friend Ramaswamy performs a song in Italian composed by Saint Francis of Assisi around 1225. The song is known as ‘the Canticle of Brother Sun and Sister Moon’, and is about the oneness and interconnectedness of the web of life.
… the song translated to English:
the Canticle of Brother Sun and Sister Moon
sweet is the feeling in my heart
now, humbly, love is born
sweet is the knowledge that I am not alone
but I am a part of immense life
that generous life all around me
his gift and his immense love
he gave us the sky and the bright stars
brother sun and sister moon
mother earth, with fruits, grass and flowers
the fire, wind, the air, and pure water
source of life for his creatures
his gift and his immense love
his gift and his immense love
