Over the last few decades, the number of private motor vehicles on the roads of Chennai has increased significantly. The increase in the number of vehicles only contributed towards promoting severe air pollution, which had to be controlled. With this in mind, a Pollution Under Control (PUC) certificate for motor vehicles was made a mandatory requirement as per the Regional Transport Office (RTO) Rules. The PUC certificate is an indicator that the emissions from the vehicles are within the permissible limit. When the PUC certification rule was first introduced, several centres were opened across the city of Chennai. Over the years…

Some Bengaluru-based startups are innovating on solutions to develop efficient batteries for electric vehicles or recycle used batteries to reduce the carbon footprint of these batteries.Electric vehicle adoption is increasing in India and in Karnataka. Key components of electric vehicles are lithium-ion batteries, which are currently mostly imported.Several of these companies claim that due to the paucity of organised markets for recycling and conventional methods, recycling of batteries remains a concern for the environment and public health. As the popularity of electric vehicles (EVs) grows in India, there are concerns about the environmental impacts of the waste they could leave…

If you could time travel to the 1800s, how would Bengaluru's lakes and water channels look? This passage from the ‘Deccan Traverses’ by Dilip da Cunha and Anuradha Mathur gives us an idea. ‘The sugarcane and rice crops looked most flourishing in the low wet land under the great tanks, which have all the appearance of natural lakes. Many of these have been most skilfully constructed, giving proof that the natives knew something of engineering, long before English rule and public works were thought of.’ The passage, referring to Bellandur Bund, is from a letter written in 1868 by Mrs…

While Bengaluru's tree-lined streets are getting fewer and fewer, it is becoming evident that the concrete infrastructure has come at a price. Several reports have attested to the decreasing green cover in urban areas. According to the State of Forest Report 2021, only 3.91% of Karnataka's geographical area has tree cover. The data also revealed that between 2011 and 2021, Bengaluru lost almost 12.9 square kilometres of moderately dense forest. "Tree cutting is presented as inevitable or as a fait accompli for any road or metro project. More often than not, how the road should progress is decided first and…

Panchasheela Nikalje, 43, almost walked into a ditch full of water one wet July morning in 2022. “I don’t know if we have more rain or worse roads, or both,” she said over the phone. It had been a long day of work swabbing floors of vitrified tile in apartments in suburban Mumbai’s Malad. “But walking to go to work seems riskier every time it rains.” A resident of Ambujwadi, a sprawling colony of informal homes adjoining a coastal swamp in north-west Mumbai, Panchasheela says she goes to work regardless of the weather. “Bahut baarish ya bahut dhoop me bhi. (On…

We have over 200 lakes in Bengaluru today. Some are amazing ecosystems, some are toxic wastelands filled with trash, and most are somewhere in the middle. Depending on who you are and where you stay, you may or may not have a relationship with your local lake. There is a lot going on though in each of our lakes, and there is a lot more that can happen with them in the future. Get to know about the history of Bengaluru's lakes and how they are connected: History of Bengaluru's lakes Early history It is said that Kempegowda’s mother told…

Rajokri Lake, located near the Delhi-Gurugram border till 2017 was a dying water body that had suffered years of toxic abuse. Domestic wastewater and sewerage from the adjoining semi-urban settlements of Rajokri village were channelled through open drains into the lake, which became a breeding ground for communicable diseases. As one resident of the area said, “It was hell living here. But today, we have a park where children play and an open gym”. In what had become a hub for anti-social elements, “it is now safe for women to venture out anytime,” added the resident. The transformation was the…

Among the many vocations and livelihoods severely impacted by climate change is the dried fish processing sector in Mumbai. Unseasonal rains lashing the coastline directly affect the produce and yield, and ultimately the business itself. The trade, entirely dependent on sunlight for its drying process, has become extremely vulnerable to the unseasonal rains, a direct result of climate change. At Madh village, between resorts and bungalows lining the coastal backyard, lies a buzzing village trading in dried fish. As soon as a boat lands at the jetty with fresh catch in baskets, the fish are sorted by the women at the jetty.…

Bengaluru, in many ways, is still recovering from the recent deluge, which caused an estimated loss of approximately Rs 225 crores and claimed 96 precious lives. Three months down the line, we are in no way even remotely better prepared for another impending tragedy. The impact of such climate change-induced disasters are only made worse by unregulated urbanisation and the unpreparedness of government agencies. The Department of Science and Technology has identified Bengaluru to be moderately vulnerable to climate change-associated risks. Yet, it is one of the only Indian metro cities that still does not have a Climate Action Plan…
