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…

As I write this, we have entered a wet and 'thunderstormy' October, but please forgive me dear reader if the weather is bright and sunny when you read this. As we found in our analysis of rainfall patterns in the city, rainfall is becoming unpredictable in Bengaluru. As early as February 2023, government authorities were celebrating full groundwater aquifers in Bengaluru. However, a few months later, as we head towards a potential monsoon deficit, the city’s groundwater levels have dipped. We turn desperately towards the Cauvery Reservoir, which is also dangerously low and sought after by farmers in Karnataka and…

In September this year, one person died due to dengue in Bengaluru. It was the first dengue death in three years in the city.

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. The protestors intended to march from Gandhi Park at Maurya Circle to Vidhan Soudha but were detained by the police.   In 2022, the BJP-led Karnataka government passed an order barring protests anywhere in Bengaluru, except 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…

Bengaluru grapples with a dengue crisis yet again and it is worth asking why. What about the city makes it ripe for a dengue epidemic? Dengue is a tropical disease caused by the dengue virus, which is transmitted to humans by mosquito bites. Most dengue transmissions are caused by one mosquito species, Aedes aegypti. This species also transmits Chikungunya, Zika, and Yellow fever. Aedes breeding behaviour Dengue mosquitoes are large, slow fliers and have distinctive white markings on their legs, making them easy to spot. As with most mosquito species, only the females bite and drink blood, usually just before…

Bengaluru has a dengue problem. According to BBMP data, the city has recorded over 4,000 cases since June this year, making it one of the hotspots in the country. Dengue is a viral infection transmitted to humans by females of the mosquito species Aedes aegypti. It is a predominantly tropical disease that affects over 5 million people in the world. Symptoms According to the World Health Organization, 80% of people infected with the dengue virus are asymptomatic or show mild symptoms. For the rest, symptoms usually begin 4–10 days after infection and last for 2–7 days. Symptoms may include high…
