It is impossible to visit Bengaluru for the first time and not be surprised by many of its urban aspects - from its noise and pollution to its ingenious ways of moving thousands of people by auto rickshaws; from its densely-packed streets to its large parks; from its lack of drinking water and its foaming and burning lake to its growing network of metro stations; from its pressing inequality to its booming IT industry; from its growing informal housing and business to its rich mixture of cultures and history, food and markets, old bookshops and new and trendy art galleries. Bengaluru presents…

A study published in the Journal of Remote Sensing and Space Sciences, analyzing the cooling effect on the city of Ahmedabad’s water bodies, has thrown up some interesting findings. The east bank of the Sabarmati river, which flows through Ahmedabad, was found to be significantly cooler than the west bank, witnessing a greater drop in temperature even during summer. The study provides direct evidence of how water bodies affect temperature variations. The Sukhna lake in Chandigarh and the Sabarmati river in Ahmedabad were taken up in the study, to assess the variations in microclimate near these water bodies. Urbanization has resulted in…

The timber mafia in Jharkhand. Rampant mining in Jharkhand and Goa. Overdependence on borewells and low groundwater recharge in Andhra Pradesh -- Deforestation, unsustainable land use practices and the slow but steady expansion of urbanised, industrial areas have led to nearly 30 per cent of India’s total land area undergoing degradation. Thus concern over desertification, which is expected to affect 900 million people in 100 countries (mostly in the global south) and which threatens almost 41 per cent of the total land area on the Earth, is a real concern for every citizen in this country. The 14th Conference of…

It has been raining on and off in Chennai over the past few weeks. And yet, 59-year-old P Mary from Saidapet has a recurring nightmare waking her up in the middle of the night every other day. In her dream, she is invariably exerting herself on the lever of the hand pump. After what seems like endless minutes of strenuous labour, water drips from the tap, drop by drop, a pale yellow colour. Reluctantly, she empties the pot, for there's a perceptible stench emanating from the water. Now, she has to again pump for another five minutes in order to…

Maharashtrians mostly believe that the popular 10-day Ganesh Chathurthi festival, which ends on Sept 12 with the immersion of idols in the sea, was first started by Chhatrapati Shivaji. Today, it is the biggest festival in the state, especially Mumbai, with Ganesh Pandals displaying larger than life idols, gaily painted and adorned with jewellery and entertainment through the night. For idol makers and sellers in Mumbai, it is a festival for making some profit. Environmental activists, however, see it -- and especially the immersion of idols in the sea -- as a disaster. Immersion of Ganesh idols usually takes place…

The Bombay High Court (HC) has become the last recourse for citizens to save Mumbai's miniscule tree cover -- less than a tree per head as aganst the world standard of seven trees per head. The city's few remaining trees are facing the axe from large, high-profile infrastructural projects. The High Court is playing the role meant to be played by the Mumbai's Tree Authority, a statutory body set up following promulgation of the Maharashtra (Urban Areas) Protection and Preservation of Trees Act, 1975. From getting the Tree Authority suspended for nine months, probably for the first time, and insisting…

With Ganesh Chaturthi just around the corner, beautifully crafted Ganesh idols have begun to brighten up the streets of Chennai. Even though the colourful, plaster of Paris idols are visibly high in number, clay ones are in the market too. According to Kumudha R, a vendor at Mylapore market, the demand for clay idols has been increasing, thanks to the awareness generated on eco-friendly or 'green' festivals. “People have become more aware of the damage caused by Plaster of Paris idols. So they opt for mud ones,” says Kumudha.  The demand is evident from the increasing price of clay which…

In India’s IT capital Bengaluru, sprinkled within its concrete jungle, are shady peepal trees adorned with serpent stones, bells and sacred threads, standing majestically atop gated, raised platforms. Often a pit-stop for tired travellers or an informal gathering place, these culturally-important open-air tree shrines or ‘kattes’ and temples, with their assemblage of native tree species, offer immense scope to enhance the green infrastructure within rapidly growing megacities, suggests a study. Offering a glimpse into the city’s native trees, the study documents 121 such species thriving in 69 sacred sites in Bengaluru, spread across 36 temples and 33 kattes, a sizeable…

There are indications that air pollution is contributing to premature deaths from cardiovascular disease in people under 40, said Dr Rahul Patil, interventional cardiologist at the Jayadeva Institute of Cardiovascular Sciences and Research. Dr Patil was speaking at the India Clean Air Summit 2019 (ICAS19). “Inhalation of particulate matter is leading to thickening of blood, with patients often showing clinical behaviours of a smoker although they are non-smokers,” he said. ICAS19 was hosted by the Centre for Air Pollution Studies, CSTEP, in partnership with the Karnataka State Pollution Control Board (KSPCB) and the state government's Department of Forest, Ecology and…
