Once the largest constituency in the city, Villivakkam has shrunk in size as many constituencies, including Ambattur, Kolathur, Madhavaram, Maduravoyal, and Virugambakkam, were carved out of it following the delimitation process. Areas that come under Villivakam including Villivakkam…

Kolathur definitely makes headlines: it is a high-profile constituency represented by the incumbent chief minister MK Stalin of the DMK. He is contesting for the 4th time from the same constituency. Located in the north-western part of Chennai, Kolathur is equidistant from both Koyambedu bus station and Chennai Central railway station, and is well-connected by road with all major localities of the city. Close by are the highly developed residential, commercial and industrial centres — Anna Nagar, Purasawalkam and ICF, respectively. Since its inclusion within city limits, Kolathur has developed rapidly. It has six multi-speciality hospitals and a few colleges, and…

It was formed in 2011 after the delimitation exercise. As of early 2026, rapid urbanisation has outpaced core infrastructure, leaving areas like Pallikaranai and Jalladianpet prone to severe monsoon flooding. The lack of a comprehensive underground drainage network leads to sewage overflows and stagnation. Despite its high revenue status, many neighbourhoods still lack piped water and sewage systems, forcing heavy reliance…

When we discuss urban nature, we often forget about real natural habitats. In Bengaluru, widely called the Garden City, most talks about urban nature focus on landscaped parks, roadside trees, and manicured gardens; in other words, artificial ecosystems designed for looks and human comfort. As lay citizens, we usually notice only such nature as we see around our homes, workplaces or other areas we generally pass by. While these places do have some ecological value, they mostly support a few highly adaptable species. This has strong negative implications for native flora and fauna that depend on open scrublands, grasslands, rocky…

Imagine you’re out on a morning walk, phone in hand, when you spot a butterfly you’ve never seen before. You snap a photo, log it into a citizen science app, and voila! You’ve just contributed to crucial biodiversity monitoring. This isn’t just a hobby; it’s part of a global movement where ordinary people collect, record, and sometimes analyse data about plants, animals, and ecosystems. Citizen science stretches the reach of ecological research. Every observation adds to unique longitudinal datasets that reveal phenology — periodic events in the life cycle of a species — along with species distribution shifts and population…

​Two decades ago, Gandhi Nagar in south Chennai was a shaded green canopy, recalls Meera Ravikumar, a resident. “Now, in the name of development, many incidents of tree felling have occurred in the past 15 years on avenues and across private properties. In highly populated and polluted urban areas, green lung spaces are important,” says the member of Swacch Gandhi Nagar, a citizens group.   Since 2000, India has lost 2.33 million hectares of tree cover, according to the 2024 Global Forest Watch. Tamil Nadu has fared better than most states — its forest cover has remained “largely stable” since…

Stormwater drains are not just “invisible infrastructure.” They are the frontline of Bengaluru’s water security. When they fail, lakes die, groundwater gets poisoned, and neighbourhoods flood. Understanding this system is the first step toward reclaiming it, because without citizen awareness, the crisis remains hidden beneath our feet. In an earlier article, we explored how stormwater drains are the frontline of Bengaluru’s water security. Part 2 of the series shows how citizens can take action themselves by learning the typology of drains and conducting audits using simple tools. Accountability gaps in Bengaluru’s stormwater worksOver the years, Bengaluru’s SWD network has been…

Every summer, Bengaluru’s water crisis makes headlines; tanker prices soar, lakes dry up, and citizens protest encroachments, fish kills, and sewage inflows. While lakes and tanks often dominate the conversation, there’s another hidden system that quietly shapes the city’s water story: stormwater drains (SWDs). These drains are more than just channels; they are the veins of a valley city. Bengaluru sits on a central ridgeline that naturally divides its water flow into two directions: Eastward: draining into the Dakshina Pinakini (Ponnaiyar) River. Westward: draining into the Cauvery Basin via the Vrishabhavathi River. Ironically, what citizens often see as footpaths or…
