varthurlake.com’, a citizen-led initiative to safeguard and rejuvenate Varthur lake

Varthur lake is the second-largest water body in Bengaluru. The 440-acre lake is located on the eastern periphery of the city, surrounded by villages and all the big IT companies. Over the last 20 years, a lot has changed and the lake has become infamous as one of the most polluted lakes in the city. From a pristine water body where people used to fish and bathe, it has now turned into a cesspool that froths and foams. It even catches fire!

Concerned by the encroachment and degradation of the lake, residents came around to start a rejuvenation campaign. The history of the lake campaign can be read here: Turning Burning Lakes Around.

In the last 5 years, much has been done by a team working relentlessly to push forward the safeguarding of the lake.

One of the key challenges faced by the team has been data collection. Data is an easy way is to understand and collate issues and problems, as articulated by Prof TV Ramachandra of the Indian Institute of Science who has been at the forefront to save the lake.

More specifically, the website will resolve issues in two ways:

  1. An easy way for citizens and residents living around the lake to share information with respect to encroachment, burning of garbage, sewage entry among others
  2. A central repository to collate data and information

Keeping this in mind, a special website has been launched to serve as a call to action, a place to register complaints and follow news about the lake. The website serves as a platform to gather real-time information, provide information on plans and rejuvenation related updates.

Here’s the website, visit now: www.varthurlake.com

All are encouraged to visit the website and share the issues that need to be addressed.

How to report issues?

It’s simple! The issues can be reported in five categories as mentioned below:

  1. Encroachment
  2. Sewage entry
  3. Garbage dumping/burning
  4. Toxic water/fish death
  5. Agricultural issues

To report any of the above issues, visit the website and click on the ‘issues’ section on the top. Select the issue and fill in the details in the google form that will pop up. The easy to use google forms allow citizens to share information about the issue along with pictures and maps of the location. Information can be shared in real-time to highlight to the authorities.

There is also an option to share information anonymously, in case of concerns. For any other queries, you can drop an email to hello@whitefieldrising.org.

Beyond the parks and gardens, Bengaluru’s ‘wasteland’ ecosystems call for protection

Open Natural Ecosystems in Bengaluru harbour rich biodiversity. Take a look at what they hold and what we risk losing to unchecked development.

When we discuss urban nature, we often forget about real natural habitats. In Bengaluru, widely called the Garden City, most talks about urban nature focus on landscaped parks, roadside trees, and manicured gardens; in other words, artificial ecosystems designed for looks and human comfort. As lay citizens, we usually notice only such nature as we see around our homes, workplaces or other areas we generally pass by. While these places do have some ecological value, they mostly support a few highly adaptable species. This has strong negative implications for native flora and fauna that depend on open scrublands, grasslands, rocky…

The wild in the city: What citizen scientists tell us about Bengaluru’s biodiversity

Spatial and temporal biodiversity patterns, as observed by citizen scientists in the city during 2016-2025, were studied at a datajam in December 2025.

Imagine you’re out on a morning walk, phone in hand, when you spot a butterfly you’ve never seen before. You snap a photo, log it into a citizen science app, and voila! You’ve just contributed to crucial biodiversity monitoring. This isn’t just a hobby; it’s part of a global movement where ordinary people collect, record, and sometimes analyse data about plants, animals, and ecosystems. Citizen science stretches the reach of ecological research. Every observation adds to unique longitudinal datasets that reveal phenology — periodic events in the life cycle of a species — along with species distribution shifts and population…
