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…

The thrust on sustainability at a citizen’s level has been evident over the last few years with a steady leaning towards greener lifestyle choices among many Chennaiites. The profusion of news highlighting the threats and signs of climate change has caught the attention of the aware and sensitive, making them realise that the adoption of earth-friendly products and practices is no longer merely an option, but an imperative. But for many others, a major stumbling block still remains: “But what can I do as an individual?” Thankfully, there are a large number of people and organisations who are trying to…

Our preferred imagination of an urban lake is mostly blue water with a well-maintained walking track all along, some trees on the periphery and some birds on them. That imagination is of course broken when the lake stinks, froths, has plastic strewn around. And when we see overgrown typha reeds in the lake, floating hyacinth and alligator weed, when the lake turns from blue to green, that imagination is broken. And then we want to rejuvenate the lake and turn it blue again. Lower Ambalipura lake / wetland If we were to step back and think why is it that…

Walking along the beach for nearly 8 km and looking for nests of turtles, dead in the middle of the night, can be both fascinating and tiring. Watching an olive ridley turtle coming to shore to nest, a process that is older than dinosaurs, can be exhilarating. If not, the waves, the sand and the conversations around the environment we live in amongst people from different backgrounds can be rewarding. The fluorescent glow of the increasingly rare Noctilucas, a bioluminescent organism, adds to the beauty of the ‘turtle walk’. However, turtle conservation is not as easy as it sounds. It also…

Over the last three decades, the lakes in Bengaluru have been ruined. Several reports list the causes and remedies, and orders were issued by the Karnataka High Court, Lokayukta Court and National Green Tribunal. But no significant action was ever taken, and the situation has only worsened. On 22nd January, citizen groups in Bellandur catchment area met Bengaluru In-charge Minister K J George, to press for time-bound and fast-track implementation of the Expert Committee Report. This was the first round, and does not address all action-points identified in the Expert Committee Report: The remaining points will be taken up in…

It was a hectic but delightful weekend at the Puttenahalli Lake in J.P. Nagar 7th Phase. On Saturday, 20th January,  S.K. Srinivas led a group of 12 participants through the intricacies of photography. It included a class in the Gazebo which we had darkened with curtains to facilitate better viewing of his presentation. Participants asked questions, cleared doubts, showed the pictures they had clicked, etc. Time flew and the scheduled two hours extended to three and more. Everyone welcomed his ideas of a day-long photo walk and forming a group so that their learning could continue. Meanwhile, we received email…
