Close to 20 people killed in the city itself, several missing and over 3000 requiring rehabilitation -- Pune is grappling with the situation in the aftermath of the September flash floods, as the city and its adjoining areas saw over 100 millimetres of rain over a period of two days. While efforts are on to redeem the situation, environmentalists and analysts say that the writing had been on the wall for some time. And the authorities had even been warned about it… Flashback to August 2019 In the first week of August, Pune experienced floods after around 100000 cusecs of…

For residents of India’s IT capital, Bengaluru, a neighbourhood park (NP) is not an uncommon sight. Their role in providing the urban population a recreational space has been appreciated by both the residents and the municipal corporation. However, their contribution to supporting the urban ecosystem and sheltering urban biodiversity has been underestimated. In a new study, a group of urban ecologists from the Ashoka Trust for Research in Ecology and the Environment (ATREE) have challenged this view. They say parks, despite their small size, can serve as “stepping stones” that facilitate the movement of birds, butterflies, and insects between larger green areas. The study…

As with any large urban centre, Chennai contributes most towards the economy of Tamil Nadu. Economic activity is concentrated in and around Chennai; multiple factories and manufacturing units are located on the outskirts of the city and there is significant commercial and residential expansion as well. This means, the city also consumes more energy and resources and as a result generates more waste in many forms. The effects of climate change cannot be ignored. Over the past few years, Chennai has witnessed extreme weather events -- from historical flooding to more recently, acute water scarcity. As the city continues to…

"You ain’t gonna miss your water until your well runs dry": Bob Marley Why did Indo-Aryans move towards Indus Valley and then to the Ganges Plain? Why did Dravidians settle near rivers? There may be several reasons. But, with the water crisis we are facing, I think we now know the answer - water. Civilisations flourished where water was available. The clock is ticking, and we need to do what is vital for our survival - save water. According to news reports, our city may turn uninhabitable in the next few years due to rapidly-depleting groundwater levels. Rainwater harvesting (RWH)…

We often hear about encroachments and solid waste sounding the death knell for water bodies in Chennai. Villivakkam Lake is no exception; it shares the same plight as any other water body in the city. However, it is set to change. Corporation officials say that the transformation of this 36.5 acre lake will be revolutionary -- replete with state-of-the art recreation facilities such as walkway, gym, children's play area, library, food and play courts, open air theatre and a multipurpose lawn. Greater Chennai Corporation will adopt Bhabha Atomic Research Centre (BARC)’s natural process of treating wastewater and use it for…
