City: Chennai

The winds are warmer, the rains are more erratic, and the oceans whisper warnings we can no longer ignore. In this age of climate urgency, our greatest hope lies not just in technology but in leadership that understands the Earth’s cry. Climate action is no longer optional, and the very people crafting policies must be well-informed. But what if they aren't? A first-of-its-kind study in Tamil Nadu by Citizen consumer and civic Action Group (CAG) takes us into the minds of our lawmakers, not to question their intentions, but to understand their climate readiness. The study assessed 20 Members of…

Encroachments on Chennai lakes often begin with the construction of religious structures, such as temples. Unless citizens take collective action, such encroachments are likely to persist. This is a key lesson from the citizen-led initiative by the Federation of Sunnambu Kulathur Residents Welfare Association to protect Narayanapuram Lake. For years, Narayanapuram Lake has faced encroachments, with four temples and a church gradually expanding into its area. Each monsoon, floodwaters engulfed the residential areas around the lake, sparing neither homes nor the religious structures. The local residents rallied together; they engaged with elected representatives, used social media to raise awareness, and…

For over seven years, I have lived in a gated community in Thalambur, located behind Old Mahabalipuram Road, Chennai’s IT Corridor. This rapidly developing suburban area enjoys proximity to some of the city’s best infrastructure, including high-rise buildings and world-class offices. However, like many other suburban neighbourhoods in the city, the local administration lacks an efficient solid waste management system. During the COVID-19 pandemic, we observed that mixed waste collected from communities was indiscriminately dumped near water bodies or on vacant land. This practice contributes to land, groundwater, and air pollution while releasing harmful greenhouse gases like methane, which contribute…

Muthulakshmi*, a sanitary worker contracted with the Greater Chennai Corporation (GCC), begins her day at 4 am, travelling from her home in Kodungaiyur to South Chennai. After street cleaning, she and her co-workers use battery-operated vehicles (BOV) to collect household waste.  Few families practise waste segregation, leaving sanitary workers like Muthulakshmi to sort mixed waste themselves. Despite BOVs having separate bins, the process is time-consuming. This is where Micro Composting Centres (MCC) and Material Recovery Facilities (MRF) play a vital role. They provide dedicated spaces to sort waste and sell recyclables in exchange for incentives. However, the GCC’s decision to shut…

Chennai recorded the highest temperature of 42.7 degrees Celsius on May 17 last year, marking the hottest day of summer so far. According to a study by Heat Watch, titled Struck by Heat: A News Analysis of Heat Stroke Deaths in India in 2024, 733 deaths due to heatstroke were reported across 17 states in India between March and June. This year, the sweltering conditions have returned early. The India Meteorological Department has issued a forecast and heatwave warning, stating that maximum temperatures will likely remain above normal by 1 to 3 degrees Celsius across many parts of coastal Tamil…

In urban areas, an unmistakable, overpowering stench often signals the presence of a waste processing facility in a neighbourhood. The foul odour emanating from these sites has long been a major concern for residents and civic authorities. It is also purportedly one of the main reasons behind the Greater Chennai Corporation's (GCC) recent decision to shut down 168 Micro Composting Centres (MCC) and 88 Material Recovery Facilities (MRF) across the city. Despite the challenges, these MCCs play a crucial role in Chennai’s decentralised waste management system. If foul odour and associated health concerns are the problem, a micro composting centre…

Across Indian cities, resettlement policies have often failed to provide long-term solutions for displaced communities, leaving them with insecure tenure, inadequate infrastructure, and limited growth opportunities. These challenges become even more apparent in resettlement schemes such as Chennai's Perumbakkam, where displaced communities were relocated into government-built apartments nearly 30 kilometres away. Antony, one of the first allottees of a plot in Chennai's Ambedkar Nagar, compares plots and apartments. He explains that having land allows gradual construction and improvements. "This is best. Here, with land, we can construct over time. There (in Perumbakkam), they cannot. There, even if they have money,…

Two years ago, I visited the Central Park South apartment complex in Old Mahabalipuram Road (OMR) to observe and write about its in-house Sewage Treatment Plant (STP). While large apartment complexes are required to have the facility to treat their sewage, many in Chennai lack one. Unlike other buildings in OMR, Central Park South had little choice, as the Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB) has yet to provide essential services like drinking water and underground drainage. I revisited the apartment this month, eager to see how the sewage treatment system had evolved. While it has had a…

Groundwater is a vital resource in Chennai, especially given the city's water scarcity challenges. Of the 51 revenue blocks in Chennai where groundwater is extracted, 46 were overexploited in 2024, as reported by Citizen Matters. That's why strict rules are in place to ensure sustainable usage and to prevent over-extraction. Chennai is the first Indian city to have a comprehensive automatic groundwater monitoring system, introduced in 2021, with 200 groundwater monitoring devices and 20 rain gauges across 15 zones, to assess the groundwater level across the city. However, experts point out that not much is being done with this data.…

வண்ணாரப்பேட்டையைச் சேர்ந்த 24 வயதான தரிஷினி, தான் தினமும் குடிக்கும் தண்ணீர் தனது உடல்நலத்தை இவ்வளவு மோசமாக பாதிக்கும் என்று ஒருபோதும் எதிர்பார்க்கவில்லை. திருநெல்வேலியைச் சேர்ந்த தரிஷினி கடந்த இரண்டு வருடங்களாக சென்னையில் தனியாக வசித்து வருகிறார். ஒரு நாள் மாலை, வேலையிலிருந்து வீடு திரும்பிய பிறகு, அவருக்கு கடுமையான வயிற்று வலி ஏற்பட்டது. மதிய உணவாக சாப்பிட்ட காரமான உணவு காரணமாக இருக்கலாம் என்று கருதி, அவர் மருந்தகங்களில் கிடைக்கும் சில மருந்துகளை எடுத்துக்கொண்டு படுக்கைக்குச் சென்றார். இருப்பினும், மறுநாள் அவரது அறிகுறிகள் மோசமடைந்தன. மேலும் அவருக்கு அதிக காய்ச்சல் ஏற்பட்டது. அவர் மருத்துவரின் அறிவுரைகளின்றி தானாக மருந்து எடுத்துக்கொண்டு இருந்தார், ஆனால் நிலைமை மோசமாகிவிட்டது. "அதிர்ஷ்டவசமாக, என்னைப் பார்க்க வந்த என் தோழி, நான் உடல்நிலை சரியில்லாமல் இருப்பதைக் கவனித்து அருகிலுள்ள மருத்துவமனைக்கு அழைத்துச் சென்றார். அங்குள்ள மருத்துவர்கள் நான் கடுமையாக நீரிழப்புடன் (severe dehydration) இருப்பதாகவும், என்…
