Do today’s modern marathon races generate a lot of the garbage and pollution that they are geared to fight? That is the question floated by a new campaign,  ‘Green the Mumbai Marathon’ started by Shilpi Sahu, a Bengaluru-based green activist who has been participating in races for almost six to seven years. She confirms that every race leads to a huge pile-up of plastic bottles, plates and tetra packs that have been used to serve water and food to runners and volunteers. With about 20,000 to 40,000 runners dumping plastic waste into lakes or nearby parks and crowding available spaces, a…

If you have travelled a reasonable number of major cities in India, the first thing that will strike you about Bengaluru is its green cover. The trees that stand regally spreading their foliage on both sides of the road, creating cool, beautiful avenues for passers-by to enjoy. These trees shield us from the fury of the sun during the warm summer months, and bear beautiful flowers in springtime. The joy that comes from watching these flowers in full bloom is truly sublime. It can transport one from mundane surroundings to a veritable paradise. Trees soothe our senses and relieve stress.…

With rising concerns about air quality in the city, a number of private citizens have begun measuring pollutant levels in the atmosphere, and are publishing them. The Karnataka Pollution Control Board (KSPCB), which is tasked with monitoring air quality and protecting the public from the health risks of poor air, disputes these measurements, arguing that these are taken by un-certified sensors. That's true, but it's also not the end of the matter. The problem is quite simple - secrecy is the weakness of pollution control efforts in the country. The government has taken the view that it will collect its…

Who we are: We are a group of four engineering students from the University of Washington working in collaboration with a local environmental NGO. For the past two months, we have been learning about Bengaluru’s relationship with its water resources. Our team has taken a particular interest in the city’s groundwater supply. We are reaching out to engaged citizens to gather feedback on our project. Background and problem Groundwater monitoring is essential in understanding the availability of underground aquifers. In the city of Bengaluru, only around half of the city serviced by Cauvery water through BWSSB’s distributed system while the…

In response to the statement issued by the Karnataka State Pollution Control Board refuting the findings of the air-quality monitoring work released by Co Media Lab and Climate Trends, the organisations have in turn issued a clarification that the exercise was done to measure peak hour pollution levels in the city for a select amount of time on select routes in the morning as well as in the evening. The objective of the study was to measure and bring to fore the personalised exposure levels one is being subjected to while traveling on busy roads for a few hours every…

The Karnataka State Pollution Control Board has issued the following rejoinder on 22nd February to the press release by Climate Trends, on the air quality data monitoring exercise, published on 19th February. [Update] On 23rd February, the team behind the study, Climate Trends and Co Media Lab issued an addendum to clarify the points made in KSPCB's statement below.  On 21st February 2018, Co- Media Lab and Climate Trends have released the report on air quality of Bengaluru City, where it is reported that there are huge gaps in the KSPCB data on the smaller particulate matter ( PM 2.5).…

Even as the gentle city of soft, light breezes, namma Bengaluru, is getting gritty with particulate matter, there seems to be a disconnect between the citizen and the data. What exactly is blowing around? Is it possible to sense and detect the quality of air? How does Bangalore rate in the Air Quality Index (AQI)? Not too good. It has been found that the biggest air pollutant in the city is particulate matter (PM), specifically PM10 and PM2.5. These are tiny, irritant suspensions in the air that tend to enter and cause respiratory and even cardiovascular diseases. In 2015, Greenpeace…

Bengaluru's air quality crisis, unlike that in the cities of the north, is a silent one; most online ambient stations which provide information to the public paint a fairly clean picture of the city’s air, though most of its citizens feel otherwise. In an effort to understand the palpable pollution levels in the air we breathe, in comparison to the ambient data being generated by the KSPCB, Co Media Lab and Climate Trends carried out a 7-day air quality monitoring exercise with the help of a low-cost monitor used to measure personalised exposure levels. The activity was spread over a…

A newly proposed amendment by the State Government to the Karnataka Tree Protection Act (1976) asks to denotify about 50 species/ subspecies of trees that currently need permission to be cut down. Simply put, if you need to chop these trees down, you no longer need the permission of the Forest Department. Media reports state that most of the species identified in this list are those which line Bangalore pathways and will deal a disastrous blow to the city’s already fragile ecosystem. The amendment however states that it is being proposed to “...exempt certain species of trees, which are grown…

A recent article on British Broadcasting Corporation (BBC) website listed Bengaluru among the 11 cities that will go out of water soon. The article said: " Local officials in the southern Indian city have been bamboozled by the growth of new property developments following Bangalore's rise as a technological hub and are struggling to manage the city's water and sewage systems. To make matters worse, the city's antiquated plumbing needs an urgent upheaval; a report by the national government found that the city loses over half of its drinking water to waste. Like China, India struggles with water pollution and…
