Ganesh Chaturthi, a beloved festival in Mumbai, is about enthusiastic celebrations, but increasingly nudging citizens to engage in deep environmental reflection. In recent years, there has been a notable shift towards embracing eco-friendly practices in the festival's preparations, particularly in the material used for the creation of Ganpati idols. According to Mumbai murtikars (idol-makers), the sale of eco-friendly idols have almost doubled this year. This shift marks a positive departure from the traditional use of Plaster of Paris (POP) idols, which can have detrimental effects on our water bodies after immersion. Many Ganesh mandals and families have taken the initiative…

Madras Week celebrations have time again proven to be a way for those in Chennai to get to know the city better.

The walk proved very illuminating on this count, with the heritage trees standing the test of time inspiring confidence for a greener…

Mayilsamy, a street vendor in Purasaiwalkam who sells toys and trinkets, remembers when the news of the single-use plastic ban broke.  “I tried to tell my customers to bring their own bags,” says Mayilsamy. “But very few people brought them.” In January of 2019, the Tamil Nadu Pollution Control Board (TNPCB) imposed a ban against the use of almost all single-use plastic (SUP) products in the state. The ban is one of many measures brought about to reduce the presence of harmful plastic products. Since the ban, the Pollution Control Board, along with other agencies such as the Greater Chennai…

In its earlier avatar, Mumbai was known as ‘Heptanesia’, denoting a collective of seven islands, as named by Ptolemy in 150 AD. With the city being transformed from a cluster of islands into a unified mass in early 18th century, its enduring connection to the coastline beholds captivating marine biodiversity that lies right at our doorstep.  There exists a facet of Mumbai that remains shadowed within the towering buildings and lost between the burgeoning crowds. Often hailed as a ‘city that never sleeps’, it also holds a hidden truth: its shores too remain in a perpetual state of wakefulness.  The…

Black, foul-smelling, stagnant water - this is what one will find when they go in search of the Mambalam Canal which was once one of the significant freshwater canals in the city.  In its heydays, the canal used to carry surplus water from two major tanks - the Nungambakkam tank and the Mambalam tank - that existed some four decades ago. Due to urbanisation, the entire watershed area of these tanks now has residential and commercial establishments in it.  The path followed by the original canal starts near Valluvar Kottam and passes through T Nagar and CIT Nagar before draining…

Varadharajan lives on the floodplains of Mudichur Lake in Chennai which was one of the worst hit areas during the 2015 floods when the water was released from Chembarambakkam lake into Adyar river.  The 2015 floods came as a wake-up call for the government and the residents of Chennai.
