‘Dirt, debris, highly acidic black water and the pungent smell,’ is the description of Otteri Nullah given by the residents living along the canal. Otteri Nullah is one of the 32 naturally formed canals in Chennai. Due to neglect over years, the canal has gone from being a vital part of the local waterway system that drains flood waters into the Buckingham Canal to a dumping ground for debris and waste.  Memories of the 2015 floods haunt many citizens of Chennai to the day. However, for residents living along the stretch of the 10.2 km-long Otteri Nullah, similar instances of…

The Chennai floods in 2015 caused damage worth Rs 8481 crore and claimed many lives. In 2021, floods ravaged the city once again, but the effects weren’t quite as bad as 2015. While estimates of the economic damage haven’t been cited; the city was at a standstill. Power had been cut, infrastructure damaged, and the collective sanity of the residents was at a low. These were dark times. Oddly, only two years before, in 2019, Chennai faced an acute water shortage because of a monsoon that failed to spill any rain. This chain of events illustrates a water paradox arising…

Rivers, the lifeline of our economy, are drying up and/or becoming too polluted. Drought and floods are becoming frequent and more intense. Addressing these challenges involves making sound data-driven and evidence based decisions in the context of the river basin. In a mature democracy, data and evidence should be in the public domain, so citizens, including policy makers, can form informed opinions and take informed actions. Once, it was the Arkavathi river that sustained Bengaluru. Running dry and polluted for almost half a century now, Arkavathi river is today biologically dead, a ghost river. It stands as living proof of…

A childhood memory of devastation caused by a cyclone that hit India’s east coast way back in 1971, left such a lasting impression on the six-year-old boy that he decided to devote his life learning about the weather and predicting unusual weather events like Cyclones. Today, that six-year-old has risen to be the 25th Director General of the Indian Meteorological Department (IMD), Dr Mrityunjay Mohapatra, also known as the “Cyclone Man”. Dr Mohapatra received international recognition for accurately predicting the path of the ferocious cyclonic storm Phailin that hit the Orissa coast in 1999. As head of the IMD’s cyclone…

According to an environment status report (ESR) released by the BMC for the year 2020-2021, 72.6% of the waste generated by residents is organic. A major chunk of this organic waste is taken to dumping grounds, which has caused recurring fires due to the high levels of methane gas it produces. Despite the BMC’s diktat to segregate wet waste at source, the implementation of it in buildings remains poor. Lack of incentives is considered to be the primary cause behind lack of focus on sustainable waste management. Not all share the apathy, though. The “Zero Garbage Project” at Surabhi Housing…

Tree leaves, bamboo, lotus leaves, palm leaves, rice straw, gourds, hemp twine, coconut shells and shells of shellfish are some of the natural materials that were used for packaging in the olden days. It was common at the turn of the century, for all items purchased, whether cooked or prepared, to be wrapped using indigenous materials, so as to preserve their freshness, prevent pollution, protect them from damage and store leftovers. Our parents and grandparents frequented small local kirana stores with steel dabbas to get flour and spices. Fast-forward to the present scenario, finding stores where you're able to purchase…

A little known fact about Chennai that came to light through a 9th Century relic found in Ambur was that present day Adyar and adjoining Adyar estuary areas were once known as Amaiyur (amai meaning turtle in Tamil). In fact, the Besant Nagar beach is especially known as a nestling area* for the Panguni Aamai i.e the Olive Ridley turtle.  Currently the turtle species is deemed endangered. Chennaiites hardly get to see these turtles on the beach as they used to in the past. Human activity such as urbanisation and commercialisation of the beach has reduced the sandy regions near the…

Taufiq, an electrician in Shivaji Nagar, sits in his shop surrounded by wall-mounted fans. Despite other shops like his in the area, he gets at least 2-3 fans for repairs daily. As Mumbai is headed into summer with temperatures touching 40 degrees Celsius in March, it’s no secret why Taufiq gets business everyday. The general ceiling fans, he says, are not cutting it anymore. “Most people here don’t have ACs or coolers, so they look for a fan that is fast,” explains Taufiq, showing me a fan unlike any other in the market. “We assemble this here. The motor comes…

Rekha, a fruit vendor in Kandivali east, has been selling fruits in the area for over 6 years now. Parked under a large umbrella that offers shade from the sun, she awaits customers. "The heat this year has been the worst in a long time, and it is only April. It will get worse," she exclaims, adding that the recent heatwave in the city has also affected her business since customers don't come out much and her fruits get spoiled in the scorching heat during the day. Rekha is also one of the many street vendors in Mumbai who conduct…

In 2020, a nationwide study, State of India's Birds, found that Maharashtra's bird population had reduced by 85% due to developmental projects that were affecting wetlands and openlands. Sunjoy Monga, a naturalist, suggested that openlands - that include grasslands and scrublands - are wrongly categorised as wastelands by the State. Concrete buildings and entertainment zones are built over them, directly influencing biodiversity in the area.  "The same trend applies to wetlands, which are highly susceptible to the activities of the land mafia, builders, lobbies and encroachers in general," he was quoted as telling The Times of India. Sunjoy has been organising an annual Bird…
