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…

BBMP has, for the first time, drafted bye-laws on Solid Waste Management (SWM). Aiming towards complete waste segregation, the bye-laws define eight different streams of waste - wet, dry, sanitary, non-recyclable, non-biodegradable, domestic hazardous, construction and demolition waste, and slaughterhouse waste. It defines specific strategies for processing each of these. The draft bye-laws also prescribe steep penalties for offences such as burning or not segregating waste, for violating the plastic ban, and so on. D Randeep, BBMP Additional Commissioner (SWM), says the penalties have been increased by five times. The bye-laws also have new provisions such as door-to-door collection of e-waste,…

Globally, air pollution reduces life expectancy by one year and eight months, on average. This loss ranks just below smoking, but above unsafe drinking water and lung cancer (State of Global Air report, 2019). Emissions from increasing vehicular population, and residential and commercial activities, are polluting even the air far from the source, and affecting the health of millions of people. Lack of scientific methods to assess pollution, inadequate data and analysis have further hampered policy efforts to improve air quality in Indian cities. The Center for Study of Science, Technology and Policy (CSTEP), a leading research-based Indian think tank,…

For the first time ever, the largest of the flamingo species, the Greater flamingos, one of the most widely recognized waders in the world, were spotted in the newly developed Sabarmati river front in Ahmedabad, much to the delight of citizens, especially the birders’ community. “I was delighted when I spotted a huge flock of about 50 flamingos when I went for a walk on the riverfront,” said hobbyist wildlife photographer Vicky Chauhan, a chartered accountant residing just 200 metres from the riverfront. “While we have seen flamingos in areas near Ahmedabad in the Fatewadi area, this was the first…

This July, the BWSSB (Bengaluru Water Supply and Sewerage Board) had warned that Cauvery water supply to the city would stop by September. Rainfall was extremely low, and water levels in the Cauvery reservoirs had plummeted. But come August, the scenario turned around completely. The two-and-half months of monsoon this year has been strange. In July end, while compiling the storage levels across all four Cauvery reservoirs in Karnataka - Harangi, Kabini, Hemavathi and KRS - I found that we were staring at the lowest water levels this decade! As the KSNDMC (Karnataka State Natural Disaster Monitoring Centre) does not…

As this article gets ready for publication, we already know of 24 fatalities caused by relentless rainfall and flash floods in Himachal Pradesh and other parts of north India. Several deaths have been reported from the capital Shimla itself, while hundreds remain stranded in various other parts of the Himalayan state. However, this is not the first extreme weather event to befall the region in recent times, nor, unfortunately, does there seem to be much hope of such disasters being stemmed. Will the allocation of some extra funds in the name of green bonus and the setting up of a…

The videos were all over the Internet and social media. Expectedly so, because you don't often see crocodiles swimming in flooded urban streets, sneaking up on strays. But that's precisely what happened shortly after news of ‘urban floods’ in Vadodara hit headlines in early August. The city witnessed scary flash floods following spells of intense rain, bringing back memories of what the city had witnessed in June 2005 and then again in the monsoon of 2014, the latter perhaps leading to the coinage of the phrase ‘urban floods’. Back in 2014, ecologists had spoken up to communicate their worries to…

In Part 1 of this series, I wrote about how we, at Sobha Quartz apartment in Bellandur, have been composting garden waste. Our compost pits are not just an ideal way to dispose of garden waste, they also yield high-quality manure for the entire garden. Our apartment association also saves around Rs 25,000 annually with this process, as we don't have to ship out the waste or buy chemical fertilisers for the garden anymore. But how exactly does composting happen? And how can you ensure good-quality compost? This part of the series deals with these questions. What exactly is ‘composting’?…

Many apartment complexes and layouts in Bengaluru have large gardens with flowering plants and trees. A lot of yellowing or dry leaves fall to ground everyday in such gardens, and these are swept away regularly. Hedges are also routinely pruned to maintain aesthetic appeal. This generates significant amounts of garden waste. Many complexes dispose off garden waste to tractor operators, who pick it up, assuring it would be dumped in approved sites. Though these operators charge stiff prices, no one knows where they ultimately deposit the waste. I would like to highlight a better, responsible way of handling garden waste, based on…

Land is already under growing human pressure and climate change is adding to these pressures. At the same time, keeping global warming to well below 2ºC can be achieved only by reducing greenhouse gas emissions from all sectors including land and food, the Intergovernmental Panel on Climate Change (IPCC) said in its latest report released on August 8th. The IPCC, the world body for assessing the state of scientific knowledge related to climate change, its impacts and potential future risks, and possible response options, saw the release of the Summary for Policymakers of the Special Report on Climate Change and…
