School boy’s documentary on Varthur Lake

“Lakes are essential to every city. They provide means of entertainment, they help local economies and they’re beautiful to look at. But many times, human activities destroy lakes, spoil the ecosystems and make them unbearable.” Harshvardhan Sanghi’s under-six-minute documentary that his mother Suman posted on Facebook caught my attention.
This Std XII student of Greenwood High International School lives close to Varthur Lake, one of the large, polluted lakes of Bangalore. Eager to help the ongoing efforts to get the authorities/ community to do something for the lake, Harshvardhan made this short film. He talks about the reasons for degredation and the possible solutions. The pollution problem is compounded by the fact that Varthur is at the end of a cascading lake series, bearing the brunt of pollution of the lakes upstream as well.
Suman says that Harshvardhan is very passionate about the environment. In the community where they live, he has been enabling the recycling of all kinds of paper, ensuring that they reach the right hands for recycling and do not go landfills. In future he wants to work in an area that will combine technology with environment.
All of us, citizens and administration, need to work together to bring about environmental change. Building up awareness and sensitivity in our children, so that they make the right choices, going against the flow if required, is an important step in this direction.

Why concrete lakes are pushing away Bengaluru’s waterbirds

As natural shorelines vanish and extensive restoration destroys habitats, city lakes see a sharp decline in special wetland bird species.

Since Bengaluru’s lakes were formed by damming water flowing down valleys, they are typically wedge-shaped, with a gentle slope and a deep basin towards the embankment. This promotes the growth of diverse vegetation and animals, each adapted to a particular water depth. The result is a natural zonation – reedbeds and shoreline vegetation at the edges, floating and submerged vegetation in the middle, and open water at the deepest end. During the Open City biodiversity datajam held in December 2025, our group examined the ecological trends around Bengaluru’s lakes. In an earlier article, we examined how migrant and resident waterbirds…

Can cool roofs beat Chennai’s heatwaves? A look inside the state’s Green Schools push

Amid heatwaves, the cool roof initiative is being implemented across Chennai schools. But experts warn that it cannot be the single solution for urban heat.

Over the past few years, maths teacher Usha found her classroom sweltering during her usual 12.50–1.50 pm period, on the second floor of Perunthalaivar Kamarajar Government Girls Higher Secondary School. “It was so difficult to take class during the peak hours,” she says. But this year, she mentions that it feels slightly bearable, and attributes this to the shade of the trees, the wind blowing through the building, and the latest addition — solar-reflective paint on the roof. Data from a state government and UNEP Cooling pilot project at the Ambattur school shows that reflective coating brought the classroom’s internal…
