Defending the city’s coast with trees that can live for more than 100 years

While the government took various measures to deal with the issue, a group called ReGreen Chennai emerged focussing only on one thing: to restore the number of trees, and at the same time, come up with an effective method to be ready for such a disaster the next time.

Initiated by the EarthSmiles Trust, the ReGreen movement has since grown into another project this year: Palmyra Nation, with an aim towards planting 2,00,000 palmyra seeds, and establish five urban micro forests in and around Chennai.

“As per our estimate, over 25 per cent of the green cover was lost, and it’s up to us to initiate a societal response to replenish that. We followed a protocol to only plant trees that are six feet and above, preferably at locations where upkeep is assured, and to plant only native species of trees which are more resistant to disaster. Over 63,000 trees were planted last year – and this year, our focus has shifted to promoting the Palmyra,” said Jegath Gasper, founder of the campaign.

The team state that the palmyra, known for longevity (living for more than 100 years), efficiently addresses all the immediate concerns surrounding drought, climate change mitigation, reducing the impact of floods and cyclones. The benefit from planting the seeds is their direct ability to conserve water and regulate the groundwater table, including the ability to mitigate saline water intrusion. 

“Moreover, the roots penetrate the water table and act as natural rechargers. The trees have uniquely strong body. During cyclonic storms and winds, they can moderate, resist and break their speed, effectively checkmating their ability to cause massive damage and destruction,” adds Gasper. The theme of their campaign is ‘Strengthen the suburbs.’ “Coastal TN is always vulnerable, so these are the areas we are focusing on.”

In addition to their efforts and working with volunteers and students all over the city, ReGreen would also hold a marathon on October 14 and an awareness drive, where each participant will be gifted a palmyra seed.
