Bengaluru has a culture of active citizenry. Groups working on various issues, such as waste, water, and other civic matters, have mostly been working in silos. Whilst a lot is being said and done on infrastructure, governance etc. the focus on climate change at a grassroots level is still missing. Now, prominent social impact networks and individuals have joined forces. Citizens, civil society practitioners, and academia have come together to launch ‘Ellara Bengaluru’, a community-driven coalition to create initiatives to make Bengaluru climate-resilient and inclusive. The coalition will work on enabling people across all wards to be fully equipped to…

Through my childhood in the nineties, all I recall about Bengaluru’s weather was that it was good, mild or fine. By mid-2000s, the talk was mostly about how the city was getting hotter. In 2020, well into adulthood, I suddenly noticed the rains. Over the course of the first lockdown, lime- washed white compound walls around our neighbourhood were turning green with moss. Sunlight started to become a rare commodity even in a reasonably well-ventilated house like mine. There seemed to be more snakes, even a frog or two. My suburban North Bengaluru neighbourhood began to look like Coorg or…

Days come and days go. And as I write this, we are on the International Day of Clean Air for Blue Skies, commemorated by the UN annually on September 7th. What this observance wants to achieve is of course pretty transparent and specific from the name itself. Sadly though, in our cities in particular, we seem to be quite far from that goal. Clean air is a luxury, blue skies a rare treat. This year’s observance comes close on the heels of the latest Air Quality Life Index report from the Energy Policy Institute, University of Chicago (EPIC), which says…

Madras Week celebrations have time again proven to be a way for those in Chennai to get to know the city better. One such opportunity was a Heritage Tree Walk organised by Nizhal and Green TN Mission, which helped me get acquainted with the greenery that the city boasts of.  With the city’s is rapidly declining green cover, it becomes even more vital to learn more about its trees and what needs to be done to protect them. The walk proved very illuminating on this count, with the heritage trees standing the test of time inspiring confidence for a greener…

The effects of climate change know no boundaries, transcending borders and impacting every individual, community and nation. India ranks third among the top 50 nations most vulnerable to the effects of climate change. Closer to home, this summer, Tamil Nadu witnessed sweltering heat waves, with the vulnerable facing the brunt of it.  Blue collar workers like Gauthaman, a water can supplier to households in Chennai, expressed concern about the escalating summer heat impacting his health, especially as much of his day is spent on the go. Nirmala, a domestic worker in the city, who also sells flowers in the evenings,…

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…

People make a landscape their city and their home. Garden City, Victory City, Steel City and many such identities are rightfully linked with urban centres across the country. When there is a mention of the most rainfall, our mind immediately travels to our middle school textbook pages that introduced us to Cherrapunjee. Water is said to be an element of nature with a memory. Often, the best of our memories of nature also happen to be related to water. The first time the waves crashed at our feet, the first time we took a dip in that meandering river, the…

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…

Urban and peri-urban agriculture (UPA) is gaining popularity in Indian metropolises to encourage climate action and sustainable development. Though the climate mitigation of UPA may be overstated, an IIT-Madras study found that UPA “can play a small, but not insignificant role” in augmenting carbon stock and bringing down land surface temperatures in cities. However, researchers say UPA has other benefits that make it critical for urban planning, such as promoting individual and community well-being, increasing urban food security and creating green jobs. Every few weeks, 53-year-old agricultural entomologist Rajendra Hegde addresses a large gathering in Bengaluru, where he puts forth…

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…
