Over 200 citizens, resident groups, environmental organisations and civil society groups have urged the Karnataka government to roll back its decision to amend the Karnataka Government Parks (Preservation) Act, 1975, which would allow portions of parks and gardens to be used for concrete-heavy infrastructure projects. Gathering at Lalbagh Botanical Garden in Bengaluru, the groups showcased a banner saying: NOT 5%. NOT 1 INCH. LEAVE OUR PARKS ALONE. "Bengaluru is becoming hotter and more climate vulnerable, yet the Karnataka government is making it easier to take away one of the city’s most important forms of natural infrastructure. Parks help cool neighbourhoods,…

On hot summer afternoons in the western part of Chennai, while many adults retreat indoors, a group of children are out on the streets with thermo-hygrometers, fluke instruments, notebooks and pens. They record heat and humidity at different times of the day, surveying residents about their experiences and identifying how heat is distributed across their locality. Trained through a joint initiative by the Chennai Climate Action Group (CCAG)'s Youth Climate Resilience Movement and the Pudiyador Learning Centre, children in Ramapuram are monitoring hyperlocal temperatures, mapping urban heat hotspots, and documenting how extreme weather impacts their community.  The exercise began after…

Imagine this: the electricity zaps off at noon during summer, and the air conditioning switches off. The sweat begins trickling down your back, and the hot air envelops your room. In these situations, Abirami DM and her family sit near the courtyard of their traditional home in Chintadripet, as the breeze filters in. This two-storey home, which has witnessed six generations of Abirami’s family, is built with materials like red oxide flooring and mud walls. “I grew up here, so I couldn’t find the difference in terms of heat until my maternal side of the family moved from a traditional…

For Dhanasekaran, a resident of Ezhilmuga Nagar, an area adjacent to the proposed Global Sports City project site, the vast stretch of land in Semmencheri is more than an empty plot waiting to be developed. Every monsoon, he watches it transform into a sheet of water, carrying runoff from surrounding neighbourhoods towards the Pallikaranai Marshland. "We are the poorvakudi (original inhabitants) of this place. Even though we were relocated here years ago, this has become our home," says Dhanasekaran, standing beside the 112-acre site where the project is set to come up. "Officials may not know how much water will…

As summer temperatures reach record highs across India, our homes are increasingly turning into heat traps. While air conditioning offers immediate relief, relying heavily on high energy-consuming cooling methods cannot be a long-term solution. These are not sustainable and contribute to carbon emissions. On the other hand, many quick DIY fixes may not work, and heavy architectural changes may not be an option for those living in rented homes or in budget-conscious households. So, how can we make our homes more liveable as cities heat up? What are some sustainable, affordable yet durable options available for cooling? To answer some…

As visitors arrive at Kempegowda International Airport, they are welcomed by lush indoor greenery designed to showcase Bengaluru's identity as the "Garden City." Beyond the airport gates, however, the reality is starkly different. Roads and streets all over the city are losing the green cover that once defined its character, to make way for metro lines, elevated corridors, and road-widening projects. Development is essential for a growing metropolis. But when it comes at the cost of thousands of trees, it raises a difficult question: can Bengaluru continue to build for the future without erasing the very landscape that made it…

Inside her 10x10 sq ft home in Pulianthope, Parvathy faces unbearably hot conditions during the sweltering summers from March to July. Green shade is a rare luxury in her neighbourhood, home to many marginalised families who earn a living making shoes. “We live right under the roof on the second floor, so it’s hot. Even if we open all the windows and doors, it does not help. Here, we end up spending more time on the streets to find respite,” she says. As temperatures continue to climb, residents like Parvathy are left with little relief. Despite July’s arrival with hopes…

Rabindra Sarobar, affectionately known as the "Lungs of South Kolkata," is at a critical turning point. As a designated site under the National Plan for Conservation of Aquatic Ecosystems (NPCA), Kolkata's living ecosystem requires dedicated protection. Authorities are not supposed to use the lake as a commercial revenue generator for municipal expenses. However, the Kolkata Metropolitan Development Authority (KMDA), as the custodian of the lake, has failed to safeguard this beautiful green oasis in the heart of the city. Many Public Interest Litigation (PIL) matters remain pending before the Kolkata High Court and the National Green Tribunal (NGT). Yet, KMDA…

Uppal is a suburb of Hyderabad, located in the northeastern part of the city. It is known for housing landmarks like the Rajiv Gandhi International Cricket Stadium and has schools, government offices, industrial zones and commercial centres. The area experiences high temperatures due to the Urban Heat Island (UHI) effect that operates within the city limits.  Our examination of Land Surface Temperature (LST) data covered the years 2015, 2020, and 2025 and shows how heat zones have expanded with warmer areas becoming larger. In Uppal, rapid urban development has changed the thermal balance. Dense construction and fewer trees  are creating  persistent…

Fifteen lakh trees. A place in the Guinness Book of Records. The Bengaluru Development Authority (BDA) has been on overdrive, promoting its new project to plant 15 lakh trees in spaces created in its new layouts. 240 acres have been earmarked across BDA’s faraway layouts. The saplings are to be planted across lake and nala buffer zones, parks and public spaces in new neighbourhoods like Nadaprabhu Kempegowda Layout, Banashankari 6th Stage, and Dr Shivarama Karanth Layout, according to the BDA Chairman N A Haris. While such massive tree plantation exercises are by themselves questionable, there is also the question of a…
