For the third time in the past five months, ESCOMs (electricity supply companies) in the state have sought an increase in power tariff,  to make up for a revenue gap of Rs 3,556 crore.  The hike will be a double whammy, as the BWSSB (Bangalore Water Supply and Sewerage Board) has said that a hike in water charges will be inevitable (BWSSB spends Rs 70-80 crore of its Rs 115 crore revenue on electricity charges). While the power hike pinches one and all, it is particularly so for apartment complexes. Besides personal consumption, residents in apartment complexes also share the…

While the city had a narrow escape during the recent landfall of Cyclone Nivar, K Srikanth, who runs the Chennai Rains blog, spent about eight hours tracking the movement of the cyclone, understanding its nature and updating his followers. “In general, the time spent on tracking the weather depends on the need. During Cyclone Nivar, I spent about three hours in the morning to share daily updates and five hours for follow-up posts and analysing the weather,” says Srikanth, who has been blogging for a decade. Srikanth is just one among a flourishing, passionate breed of weather bloggers in Chennai,…

It is magic at the DPS Lake these days. Located near Palm Beach Road behind Delhi Public School, Nerul in Navi Mumbai, the lake is home to many different species of birds. At this time of the year, the flamingos stand out and they are there in thousands! Flamingo City. (Pic: Malcolm Stephens) (Pic: Malcolm Stephens) Greater and Lesser flamingos fly in to Mumbai every winter from Kutch, Gujarat and Sambar Lake, Rajasthan. They are also known to come from other countries such as Pakistan, Afghanistan and Iran. The winters are harsh there, and apart from the warmth, the shallow…

When 25-year-old Vivek Gurav, working in an IT company in Pune, came across a video of Swedish native Erik Ahlström on YouTube, it struck him that this might provide a way of reducing plastic waste and be a way to bring youth to become volunteers of change. “I come from a small village near Kolhapur and I used to swim in the river flowing near my village,” recalls Vivek. In Pune, it saddened him to see the city’s water bodies covered in garbage and plastic waste. “While a student of MIT institute of Computer Engineering in Alandi, Pune, I was…

“We don’t know what your commission is doing. People in Delhi are not satisfied with your work. We are also not satisfied”. These remarks were made by a Supreme Court Bench headed by Chief Justice of India S A Bobde on December 17th. That was six weeks after the ordinance on “Commission for Air Quality Management (CAQM) in National Capital Region and Adjoining Areas Ordinance 2020” was promulgated on October 29th. The super commission subsumed practically every other law and agency dealing with air pollution in this region. Solicitor General Tushar Mehta responded to the judges’ scathing comments saying the…

To a mind that’s taught to see vast swathes of land where no large trees but “mere” grass and shrubs grow as inconsequential, Hesaraghatta’s distinction as a unique habitat for flora and fauna may come as a rude shock. Here, the view is just grass, with a few trees to break the monotony, a dying river skirting the landscape, and a man made lake dependent on annual monsoons to validate its worth. So, to truly appreciate the biodiversity hotspot that Hesaraghatta is, you have to either look up at the sky or peer hard into the ground.  Around 235 species…

Due to rapid urbanisation and unplanned development, Bengaluru’s groundwater is getting increasingly contaminated. This issue requires urgent attention as approximately 40% of the city's population depend on groundwater (borewells, open wells and tankers) for their daily water needs such as drinking, cooking and bathing.  Contaminated groundwater could lead to health issues if it is directly consumed. If used for agricultural purposes, it could even enter the food chain.  Residents across the city have reported that borewells discharge coloured or smelly water. This indicates percolation of sewage and chemicals into the water table. Discolouration, cloudiness and bad odour are some of…

Sandwiched between the swanky Bandra Bandstand and posh Carter Road promenades lies the rocky patch of Chimbai beach, that continues to be a source of dirt and squalor. Though the Brihanmumbai Municipal Corporation (BMC) regularly cleans the narrow sandy stretch with dumpers and JCB machines, the beach continues to stay dirty and unattractive, unlike the promenades on both sides, that have become vibrant and popular community spaces. A survey by NGO ReefWatch Marine Conservation had named it to be the filthiest of the ten beaches of Mumbai. Photo: Hepzi Anthony 46-year-old Pravin Gohil who has been staying here since his…

Climate change is leading to a rise in extreme events the world over, and developing countries such as India have been experiencing not only higher death rates but also greater economic impacts due to natural hazards. Urban areas in India have been found to be particularly vulnerable to floods due to unplanned developmental activities, change in land use patterns, overcrowding as well as increase in natural hazards such as rise in sea levels, storms and cyclones. This paper 'Investigation of role of retention storage in tanks (small water bodies) on future urban flooding: A case study of Chennai city, India'…

What do the trees, water bodies, agricultural fields and forests mean for a city like Delhi? Can we ascribe a monetary value to their contribution? These are some of the questions that a team of Delhi-based scientists recently tried to answer and found that rapid and unplanned urbanisation in Delhi during the last two decades (1998-2018) has happened at the expense of many natural and semi-natural elements and it has resulted in a loss of about Rs. 560 million (US$ 7.614 million). The study showed that the biggest contributor to this loss was the decline in the city’s forest cover, which declined…
