A recent report by the Environmental Management & Policy Research Institute (EMPRI) finding heavy metal contamination in vegetables sold in Bengaluru markets has sparked concern among the city’s residents. The report, which was written in November 2022, was featured by the Deccan Herald in October this year. The report found that 10 common vegetables, including tomatoes, onions and spinach, were found to have unsafe quantities of heavy metals. We look at the main findings of the study. What are heavy metals? Heavy metals literally refer to metals that are dense or heavy in terms of their atomic weight. These metals…

A once iconic bird in Bengaluru’s lakes is now a rare sight. Spot-billed pelicans, which are fish-eating water birds, were common, especially in large lakes across the city. Huge flocks of over a hundred birds would occupy lakes like Madiwala, Hebbal and Jakkur. But today, birdwatchers celebrate even sighting a handful of these birds. The decline in the city is linked closely to mass deaths of the species in their breeding sites in the Mysuru-Mandya region. But the exact reason is a mystery. Spot-billed pelicans or Pelicanus phillippensis are one of eight species of pelicans in the world and are…

Can Bengaluru be water resilient? Urban water researchers Rashmi Kulranjan and Shashank Palur from WELL labs have previously outlined how the city can reduce its dependence on Cauvery water, reuse groundwater and allow lakes to act as flood control systems. However, the first step to building water resilience is understanding the different sources of water in the city, how much water is used and how much remains. WELL labs released Bengaluru's first water balance in October this year, co-authored by Rashmi Kulranjan, Shashank Palur and Muhil Nesi. Here are the key insights from the report. Water management in Bengaluru Rashmi…

For birdwatchers, naturalists or concerned citizens curious to know more about the wildlife in their neighbourhood lakes, parks, and gardens, a new tool offers an exciting opportunity. Mapping Your Neighbourhood Avifauna or MYNA, a data exploration tool, allows users to visualise birdlife in green spaces around their neighbourhoods. MYNA is a data exploration tool created by the State of India’s Birds team. The State of India’s Birds (SOIB) is a report that assesses the status of over 900 bird species in the country, using citizen science data. The data comes from hobby birdwatchers or citizen scientists, who record their observations…

If you lived close to a metro station, would you use the metro for your daily commute? The answer is not so obvious. A study by researchers from the National Institute of Advanced Studies (NIAS) found that the urban poor in Bengaluru do not prefer the metro even when it is located close to their homes. The study found that the Bengaluru Metro Rail Corporation Limited (BMRCL's) metro system was unaffordable for these residents, who instead relied on walking, BMTC and two wheelers. However, a few tweaks can make the metro more accessible and sustainable than it is currently, according…

There is a small patch of land adjacent to the Baiyappanahalli metro station. This is the first stop for the mobile Alli Serona bus stop, a colourful art installation. The roof of the bus stop is draped in colourful fabric, the inside features tablets for visitor surveys, digital screens with the story of the bus stop and a single red chair. If you sit on the chair you are voting for a bus stop. Over four hundred people did that on the first day of the exhibition on October 5th. The beginnings of Alli Serona The bus stop is a…

[In part three of this series, Citizen Matters spoke to urban hydrologists and researchers, Rashmi Kulranjan and Shashank Palur, about how Bengaluru can reduce dependence on external water sources, like Cauvery, and become water resilient.] In this interview, the researchers say that the first step towards achieving the goal of resilience is to understand water usage by building a water balance for the city. About the researchers Rashmi and Shashank work at the Urban Water Programme at WELL Labs, where they study water flow patterns in urban water systems, especially lakes in Bengaluru. Rashmi is also a PhD scholar at…

Students, women, farmers and Dalit groups gathered together on October 2nd, Gandhi Jayanti, to demand the withdrawal of a government order restricting protests to the confines of Freedom Park.

Since its enforcement, the order has been used to arrest a wide range of protesting groups, including Citizens for Sankey, a group that opposed the proposed widening of Sankey Road, farmers from Devanahalli…
