The occasional spells of rains have brought some relief to Chennai. But that should not cloud the fact that the city went without any significant rainfall for about 200 days at a stretch. Rainfall patterns have become erratic in Chennai, with a spike in extreme weather events such as cyclonic storms and heat waves. Even though a large number of people -- in civil society as well as in the government -- are sceptical about attributing it to climate change, scientists do feel that there is a strong connect. Citizen Matters Chennai spoke to Dr V Selvam, former Executive Director…

One morning, nearly a month after Cyclone Fani struck Odisha, Ashok Baral, a citizen of Bhubaneswar, came upon a fallen trunk of a banyan tree near the Stewart School boundary wall. The tree had been uprooted by the cyclonic storm Fani, which hit the city on May 3, 2019. Recalling that particular moment, Ashok says, “Though it was my regular route home from the milk vendor, it seemed as if the helpless trunk of the tree was trying to tell me something on this particular day. I stayed there, looked at the trunk for some time, and wrote a message…

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…

One among the first 20 cities selected for redevelopment under PM Narendra Modi’s Smart Cities Mission (SCM) launched in 2015, Bhopal faces the loss of a major chunk of its green cover, thanks to the implementation of the smart city project. The number of trees that could literally go under the axe may run into thousands under the Rs 3400 crore development plan in the city, which is still grappling with the consequences of the world’s worst industrial disaster -- a gas leak that killed thousands in 1984. The area chosen for implementing the project, Tatya Tope Nagar (TT Nagar),…

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…
