Across Bengaluru, apartments have been popping up like mushrooms over the years. This poses several challenges to the city, including waste management. Though BBMP (Bruhat Bengaluru Mahanagara Palike) has introduced many rules that require apartments to manage their own waste, not all apartments follow these. Some apartments face practical difficulties such as lack of space or the heavy investment needed to install a composting unit. The poor management of waste affects not just apartment residents, but all citizens. But the solution could be quite simple. Back in the olden days, people used to segregate and compost their wet waste - mainly…

Alia, 15, cannot move or talk. “She is totally dependent on me,” said her father Mohammad Asad, an electrician. “Her mother passed away almost nine years back. I have to remain with her most of the time”. Even 35 years after the world’s worst industrial disaster that claimed 3787 lives in one night (unofficial estimates, however, put the number of deaths at over 20,000 till date, including those who died from gas related illnesses since) and left 500,000 permanently ill, victims of the Bhopal gas tragedy continue to suffer the effects of the deadly gas leak from the Union Carbide plant.…

It is almost as tall as the Qutb Minar and growing in height every day, threatening to grow taller than the Taj Mahal. It spews deadly methane gas into the atmosphere and pollutes ground water. It provides a risky and toxic living for ragpickers and is a major health hazard for all those living around it. It claimed two lives when a part of it collapsed in 2017, and poses a continuous fire hazard. And yes, it is causing changes in the climate of the city. This is the Ghazipur landfill in East Delhi, now represented in Parliament by former…

Air pollution is now the leading cause of death in India. It accounts for 1.2 million deaths, more than the number of people killed by malaria, smoking or road accidents. Last year, a study by the Central Pollution Control Board (CPCB) found that Bengaluru topped the list of major polluting cities in India. More recently, measurements of pollution level using hand-held devices show that particulate matter pollution levels in many places in Bengaluru are substantially higher than the levels in Beijing, China and yes, even New Delhi.  More alarmingly, pollution levels in Bengaluru are expected to skyrocket over the next…

This summer, Bengalureans faced another gruelling water crisis. So much so that residents even in core areas of the city had to start buying water from private tankers. And in outer areas, even private tanker supply was inadequate. We had earlier published a guide on building recharge wells to capture rainwater this monsoon. Another way to meet your water requirement is by treating and reusing the greywater generated in your household, especially if you live in an independent house. What is greywater? Greywater is simply soap water; it's the wastewater from bathrooms, washing machines etc. Greywater does not contain much…

Since schools have reopened, children, who are more at risk from air pollution, have been facing high levels of exposure. Air Quality Index (AQI), measured by monitors across the city, show that air quality is often poor. For example, on June 5th, the AQI at BTM Layout was 159, which falls in the 'unhealthy' category. At this air quality, children and the elderly, as well as people with lung and heart diseases, may have discomfort breathing. Anti-pollution masks can help reduce exposure to pollutants and minimise health impacts. Here is an overview of different types of anti-pollutant masks, and tips…

For what might come as a breath of fresh air for Bengalureans quite literally, the Karnataka State Pollution Control Board (KSPCB) has stepped up to tackle air pollution in the city. A 44-point joint action plan has been approved by the Air Quality Monitoring Committee (AQMC) that was set up by the Karnataka government in response to a directive by the National Green Tribunal (NGT). In addition to Bengaluru, action plans have been created for Hubli-Dharwad, Davengere and Kalaburgi. These are the four ‘non-attainment cities’ in Karnataka, i.e., cities that do not meet the National Ambient Air Quality Standards. As…

Buddha Nulla, or Buddha Dariya as it was once known, is a symbol of all that is wrong with Ludhiana, Punjab’s largest city. Old timers in Ludhiana remember a cool seasonal stream, a tributary of river Sutlej, that flowed through the city and rejoined the river 16 kms downstream. "It was I think in 1977 or 78, I was in class seven,” recalls Arun Chatwal, born and brought up in Ludhiana. “Both banks of the Buddha Dariya used to be a place for social gatherings. My father used to take all of us as kids there, and some of the…

‘Beat Air Pollution’ is the rallying call issued by China, which is hosting this year’s World Environment Day celebrations.  And China knows how to beat air pollution, for it has worked hard the past two decades doing just that. According to a report released this March by the Beijing Municipal Ecology and Environment Bureau, 20 years of tough action has produced the following results: “the average concentrations of sulfur dioxide, nitrogen dioxide, and fine particle PM10 dropped by 93.3, 37.8 and 55.3 percent respectively in Beijing. The PM 2.5 content in the air reduced by over 40 percent.” United Nations…

Few citizens in Mumbai are seen wearing a mask outdoors; fewer are actively concerned about air pollution. “It’s not as bad as Delhi”, most say, and inevitably point to the winds that blow from the surrounding sea. The murky, grey and polluted water might make them reconsider their statement, but the feeling that Mumbai is better than the northern landlocked cities wins. But when winter arrived last year, the sea winds failed Mumbai. In the month of December, temperatures dropped in the city but pollutants remained trapped in the atmosphere. The overall air quality index (AQI) was reported to be…
