In the OpenCity Bengaluru Design Jam on BBMP, our team analysed and debated the bylaws and zoning rules governing civic amenities, parks and open spaces in the city. As a diverse group of spatial thinkers and design creatives, we sought to understand what liveability meant for citizens navigating the urban landscape, and how building and zoning laws address our needs and the city’s densifying future. Urbanisation is transforming cities worldwide, significantly impacting the quality of life both socio-economically and environmentally. In democratic societies, livability crises affect and are affected by the different levels of urban growth and how cities are…

A lake is not just a body of water, it is an ecosystem. Action Aid Association India organised a survey to document the biodiversity of Dorekere, a lake in South Bengaluru. The biodiversity survey was funded by the Australian Consulate in Chennai. It not only documented several species but highlighted the importance of such an activity in understanding whether Bengaluru lakes are being developed in an ecologically sound manner. Dorekere is a 28-acre lake in the Uttarahalli suburb of South Bengaluru. The Bruhat Bengaluru Mahanagara Palike (BBMP) currently manages the lake. Earlier, it came under the purview of the Karnataka…

Peenya Industrial Area, one of Bengaluru's oldest industrial hubs, is facing a significant challenge — rising urban temperatures exacerbated by the Urban Heat Island (UHI) effect. The aggregated maximum Land Surface Temperature for the first 8 months increased from 43 ℃ in 2023 to 46 ℃ in 2024, as derived from the ECOSTRESS sensor. This phenomenon, in which urban areas experience higher temperatures than their rural counterparts, is particularly pronounced in Peenya. The area’s industrial growth, coupled with a lack of green cover and the prevalent use of heat-absorbing materials, has made it one of the hottest zones in the…

In July, some members of the Valmiki Nagar Residents Group wanted to address the problem of overgrown trees, support newly planted saplings, prune trees along the avenues, and curb the growth of invasive species. A few of us at the Association thought it would be a good idea to form a smaller committee to research and supervise the growth of trees, the different species in the area, and their proper care.

On October 16, 2015, I came across a newspaper photo that left me aghast — women performing Chhath Puja in the frothing Yamuna River. Chhath Puja is an important festival for Hindus in Uttar Pradesh, beginning and ending with a dip in a water body. This festival is known to be one of the most eco-friendly celebrations among Hindus, involving rituals performed in natural settings, using natural materials, and respecting the environment. However, the sight of the river submerged in toxicity starkly contrasted with the nurtured love and respect for divinity in its natural form. The river languished in a…

Nilesh Shinde, the organiser of the Mumbaicha Samrat Ganpati at Khetwadi, is confused. Just as many other organisers of Mumbai's famed Ganeshotsav, he has also been preoccupied with the Bombay High Court's recent order. The Court, in its order, asked all civic bodies to intimate sarvajanik Ganesh mandals that they have to mandatorily follow the Central Pollution Control Board  (CPCB) guidelines of 2020 and shun PoP idols altogether. Yet, not all are aware of the rationale behind this."Why didn’t they put a ban on PoP for the past so many years? It is not as if people have started celebrating…

Jakkur Lake is on the outskirts of Bengaluru, north of the bustle of the city centre. There is a strong breeze in the morning, but the lake lies calm. Cormorants stretch out their wings to dry. Runners stretch their legs before jogging the 5 kilometre path around the lake.  Just as the lake serves the surrounding community, the community serves the lake. Jala Poshan, or “Nurturing Water” in Hindi, is a community-led trust that works to create a healthy community space around Jakkur Lake. The creation of the trust was initially facilitated by Satya Foundation, which provided funding and fostered…

As dawn breaks, there is a steady stream of customers at Muhammed's tea shop in Chennai. As they arrive, he serves them tea in glass tumblers. However, one customer insists on a paper cup for hygiene reasons, despite Muhammed explaining that the glass tumblers are washed and sterilised with hot water. Glass tumblers cost around Rs 20 each and can be reused hundreds of times until they break. In contrast, paper cups cost Rs 100 for 50 cups (Rs 2 per cup) and are neither reusable nor environment-friendly. “Though plastic-coated paper cups are banned, we can’t avoid using them when…

Bengaluru has numerous parks and lakes, where we all love to walk and run. However, the city lacks proper walking, cycling, and running infrastructure. Daily walking for errands is nearly impossible due to broken sidewalks, exposed wires, and construction debris everywhere. Attempting to use a bicycle or run on the roads puts one at risk from heavy vehicles, cars, and other traffic.  Sheela Sahi, a commuter, on her way to work on her cycle.
