A wide range of people from all over Bangalore, representing a range of organisations and communities from within the city, peri-urban areas and villages affected by waste disposal, were present when Justice N. Kumar (Retd.), Former Judge of the High Court of Karnataka, released: “Bangalore’s Toxic Legacy Intensifies: Status of Landfills, Waste Processing Sites and Dumping grounds, and working conditions of Pourakarmikas”, a report prepared by Environment Support Group. This report provides a critical framework to evaluate the progress achieved in advancing environmental and social justice of communities impacted by waste handling and disposal, and is prepared to support ongoing…

For an effective air quality management plan, a lot of information is required at various stages to ascertain the sources, their impacts on health, and their potential to control emissions. However, the most basic information that every city requires is ambient monitoring data. This data tells us, what is the level of air pollution, where and when is it the highest (spatial and temporal trends). It is very important that the ambient monitoring network for a city is representative, spatially and temporally, to support an effective long-term air quality management plan for the entire airshed of the city. For example,…

A recent BBC report projected that Bengaluru will run out of water soon. Yes, it was a superficial list of cities that already have water problem. It just pronounced the harsh verdict without any in-depth analysis of the factors involved. That’s like taking a casual look at an emaciated man and saying, “he is going to die soon”. But in this case, all the x-rays and MRIs are only going to confirm the same verdict. Ignoring the problem is going to worsen the situation. Let’s have a look at this complicated case, Munnabhai-style. He is bound to say, “Ae maamu!…

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…
