bengaluru lakes

Reports of massive fish kill events in lakes across Bengaluru come up worryingly often every year after the first monsoon showers. This year was no different. Ulsoor, Basavanapura, Muthanallur and Bhattarahalli are some of the lakes in which dead fish were found floating over the last few weeks. What is causing this morbid scene year after year in a city famed for its many water bodies? Pollution is one culprit. What are the other factors involved? How exactly do these interact and impact lake ecosystems? And what needs to be focused on to prevent such events? To understand the whole…

One of the characteristic features of a lake is its colour.  You may have noticed that the water in many lakes in Bengaluru is green, and not blue, as you might have imagined it to be. This is due to the presence of algae. Algae are microscopic plants that contain chlorophyll which is the pigment that gives it a green colour. While some amount of algae is healthy for the lake ecosystem, excess algae can be harmful and is an indicator of a polluted and nutrient-rich lake. Lakes rich in nutrients such as nitrogen and phosphorus are called eutrophic lakes,…

Bengaluru’s lakes have been in the news for pollution, froth, fish kill and even fire. Despite the government investing crores of rupees into reviving these lakes, and widespread citizen engagement, not much has changed. While the main reason is the lack of coordination between government departments, the absolute lack of science-based solutions is also a major gap. In this context, Ashoka Trust for Research in Ecology and the Environment (ATREE) and Biome Environmental Trust (BIOME) have developed the ‘Bangalore Citizen Science Lakes Dashboard’ to share knowledge and best practices for better management of lakes. We created a series of system…

Most Indian cities have a distinct historic past, rooted in the natural, social, economic and cultural contexts of different times. A strong relationship with nature and its processes is the most significant aspect of these cities’ development and survival. Landscape Foundation, India initiated the pilot study of the city of Delhi (Delhi – Hills, Forests and a River, 2017) in this context. This was followed by the study of Pune (The City of Hills and Rivers, 2018). This year, the study of Bengaluru was undertaken. The research, in each case, is produced in English and the regional language, as to…

Bengaluru faces another water crisis this summer. It's not just citizens who are responsible for this situation. For decades, the state government and civic administration have been focusing on short term strategies, without assessing whether these are sustainable. The main cause of the current crisis is that we have no clue where our resources come from, what their limits are, and we don't value what we have. The city has destroyed its water security - the 1800 lakes that our forefathers built here, are down to less than 200 now. And even these remaining lakes don't have potable water. If…

Two years ago, many of us came together with an idea - to save the local lake that we lived near. The situation was dire. Rachenahalli Lake located near Srirampura Cross, Jakkur, Bengaluru, like many other water bodies in the city, is part of an interconnected system both upstream and down. Though the Bengaluru Development Authority (BDA) had spent a substantial sum of public money to rejuvenate it about eight years ago, it had turned into a drain for the sewage water being released by the upscale apartments that surrounded it. The situation had taken a turn for worse because…

Over the last few years, many of Bengaluru’s lakes have gone through rejuvenation processes as described in the first part of this series, that completely transforms and restores lakes to beautiful common areas and thriving ecosystems. Behind every lake is a group of community members pushing for rejuvenation, government assistance or simply rolling up their sleeves and getting their hands dirty in an effort to save a lake. Transforming a dead or dying lake is no small feat. Many hands have their stake in the rejuvenation. For many lakes, the rejuvenation process is a result of local community members and…

‘An early morning run at Lalbagh. Yippee!' That was my spouse displaying objectionable amounts of enthusiasm at a time one should still be curled up in bed. Propping my bleary eyes open with my fingertips, I cautiously allowed the daylight in. Only to find there wasn't really much of it out there yet. Would have dropped off again, but could't go back to sleep. Reluctantly popping out of bed, I proceeded to soothe my jangled nerves with a refreshing cup of tea.The milk delivery was more than an hour away. No second cup of tea till then. The newspapers were…
