Over the past few decades, North Chennai has seen pollution taint its air, land and water. Studies by various organisations have shown that a key factor behind the rising pollution in North Chennai is the major industries that operate in the Ennore-Manali region, including the state-owned thermal power plant. Pollution has affected the lives of scores of residents in North Chennai and robbed many of their livelihoods. While the polluters should be held responsible, it is equally important to hold the regulator, the Tamil Nadu Pollution Control Board (TNPCB), accountable. The TNPCB has been entrusted with the duty to curb…

கொரட்டூர் ஏரி 20 ஆண்டுகளுக்கு முன்பாக சமையலுக்கு குடிநீருக்கு பயன்படுத்தி வந்துள்ளனர் ஆனால் தொழிற்சாலை மற்றும் பால்பண்ணை நச்சு கழிவுகளால் ஏரி மாசடைந்தது இதனால் நீரை பயன்படுத்த முடியவில்லை. நிலத்தடி நீர் சுற்றி பாதித்துள்ளது கழிவு நீரால் ஆகாயத்தாமரை அதிகம் வளர்ந்துள்ளதால் மீன்களின் இனப்பெருக்கம் குறைந்து வருகிறது ஏரியைச் சுற்றிலும் 200க்கும் மேற்பட்ட மீனவ குடும்பங்கள் வாழ்ந்து வருகின்றனர் இவர்களின் வாழ்வாதாரம் ஏரியை நம்பி தான் உள்ளது ஏரி மாசடைந்து மண் மற்றும் தண்ணீர் பாதிப்பால் மீன் இனப்பெருக்கம் குறைந்துள்ளது. ஆக்கிரமிப்பால் ஏற்படும் மாசு  ஏரியைச் சுற்றிலும் அரசியல் போர்வையில் சமூக விரோதிகள் தொடர்ந்து ஆக்கிரமிப்பு பணியில் ஈடுபட்டு வருகின்றனர். ஆக்கிரமிக்கப்பட்ட பகுதிகளில் சென்னை மாநகராட்சி எல்லா வசதிகளையும் செய்து கொடுப்பதால் ஆக்கிரமிப்பாளர்களுக்கு வசதியாக போய்விடுகிறது. ஓராண்டுக்கு முன்பாக கோர்ட்டு ஏரியில் ஆக்கிரமித்துள்ள 12 வீடுகளுக்கு நோட்டீஸ் வழங்கப்பட்டது 21 நாளைக்குள் காலி செய்ய வேண்டும் என்று ஆனால் இதுவரை எந்த…

Citizen Matters, Bengaluru, is gearing up for an exciting conversation with the Environment Support Group (ESG) as they turn 25 this year. Representative image. ESG works to mainstream the rights of local communities and voiceless ecosystems. Pic: Kavitha N Kishore ESG is a pioneering environmental organisation that was pivotal in creating awareness on environmental issues plaguing Bengaluru. Over the years, ESG has fought to stop destructive roads projects and pushed for preservation of lakes and our vanishing greenery. The organisation has been vocal in speaking for public commons and environmental justice and has fought several legal battles to prevent destruction…

For the record, Gubbalala Lake, located in Raghavendra Layout close to Vajarahalli Metro Station, is an eight-acre 10 gunta waterbody. In reality, it occupies just four acres and 20 gunta. It is suspected that about two acres of the lake’s land have been encroached upon. The lake has four inlets and one outlet, with a walkway length of 810 meters and a main bund length of 160 metres. The catchment area is about two square kms. The lake is situated in the 110 villages scheme/areas of BWSSB (BBMP vide a notification in the year 2008 acquired gram panchayats with 110…

The K-100 stormwater drain cuts across 23 wards in the city as it traverses from its source near Majestic Bus Stand to its destination – Bellandur Lake. The geographies of these drains and its surrounding areas serve as important starting points in understanding city planning and the context of urban floods. The ‘K’ in the K-100 stands for the Koramangala Valley and the ‘100’ denotes that it is the first primary stormwater drain (SWD) of the valley. The K-100 has multiple secondary and tertiary drains, numbered K-101, K-102 etc. intersecting at different points. The drain serves a catchment area of…

In recent years, we have seen a dramatic rise in instances of flooding, along with increasing population density and expanding concrete surfaces. All these add extra pressure to the stormwater drain networks, which also put people living near drains at risk. Therefore, the question that arises is do we need to revisit engineering designs of stormwater drains? Pipes and sewage drains, symbolic of the colonial period, displaced the traditional systems of water from wells and lakes. This is because piped water, which brings water into the city, and drains, carrying sewage out, were viewed as indicators of modernity. The problem…

Residents of Chokkanahalli and Sampigehalli have been fighting to save their neighbourhood lake, Venkateshpura Kere. The lake was listed as 10 acres 35 guntas by BDA and BBMP until a few years ago, but has slowly been reduced to 6 acres and 35 guntas on paper. Read more about this in part 1. The remaining four acres, which comprise the lake watershed area, has been notified as a Civic Amenity (CA) site by BDA; part of this has been leased to a private trust. BBMP, which is the custodian of the lake, has done little to address the concerns of…

Distraught residents of Chokkanahalli, a neighbourhood near Jakkur in North Bengaluru, watch everyday as a rocky outcrop, which is part of a monument, is demolished by a private trust. The remains are currently being dumped into their neighbourhood lake, Venkateshpura. Chokkanahalli Sampigehalli Abhivriddhi Forum (CSAF), a residents group in the area, alleges that the BDA notified a portion of the lake as a Civic Amenity (CA) site and allotted it to a private trust. They have been trying to stop the construction and demand a resurvey of the lake. But neither BDA, which has allotted the land, nor BBMP, which…

Climate change is experienced in the form of erratic, unpredictable and extreme weather changes in the various seasons. This is impacting the periodic appearance of leaves, flowers, and fruits on the seasonal trees around us. Observing these changes regularly can give an insight into climate change's impact on biodiversity in India. Since trees are the basis of all life, including ours, understanding the impact of climate change on trees is imperative. For over a decade, SeasonWatch is leading a citizen science project following the patterns of emergence and maturation of leaves, flowers and fruits (“phenology”) on common tree species of…

In May 2022, Bengaluru’s flooding issues prompted Chief Minister Basavaraj Bommai to announce modernisation of these drains in an integrated manner, at a cost of Rs 1,600 crore. BBMP then authorised zonal commissioners to take up emergency work worth Rs 1 crore and this included removing silt in all drains. The BBMP engineers were also directed to identify low-lying areas and other vulnerable areas in the city. Housing Minister V Somanna stated that all engineers would be held responsible if flooding persisted during monsoons. The August-September 2022 rains did see more flooding. But no official was hauled up. Removal of…
