As one of India’s largest and most populous metros, Chennai exhibits all the traits and vulnerabilities inherent to a developing, high-density city. Rapid urbanization has led to pollution, poverty and energy and water scarcity.  However, one of the key issues with the city is a pronounced lack of civic consciousness. Resilience working group sessions (led by the  Resilient Cities Network chapter in Chennai) involved experts from government, civil and academic bodies. They concluded that in order to achieve sustainable development goals and build resilience, civil ownership and participation was essential. These are the top three areas where citizen participation and involvement…

The theme for World Environment Day observed earlier this week was ‘ecosystem restoration’ and it presents a good starting point for an important conversation – one about urban agriculture (UA) and its potential to revive and restore highly diverse ecosystems in cities. Initially, a majority saw urban agriculture largely as a hobby of a scarce few with enough time and a ‘green thumb’ practice. But today, many recognise its vital role in building more sustainable, climate-proof urban futures and are taking active interest in the same. The pandemic and consequent lockdowns have, in fact, spurred an interest in urban agriculture…

Even before summer had set in officially, the two borewells at S Velu’s residence in Selaiyur turned dry in April. In search of water, he dug another borewell as deep as 600 feet, but that too failed to yield any water. Velu is now at the mercy of water tankers and municipal water supply and uses water sparingly. Although Chennai’s water situation is not as alarming or critical as it was in 2019, groundwater resources in several pockets of the city are reportedly drying up. As a result, besides using water supplied by the Metrowater agency, many households and industries…

These are no ordinary trees. These are the birds, the butterflies and the bees. These are where our kids sat immersed with books, stories and workshops in the annual children’s book festival. A fellow mom asks me, Where will kids have beautiful story sessions now? True, it wasn’t just the books but the magic of being in the lawns of the Indira Gandhi National Centre for the Arts (IGNCA) each spring season, frolicking and giggling under these angel guardians. And yet, 1,838 of these trees in and around the IGNCA campus, and the road in front of National Archives, are…

The Indian Meteorological Department (IMD) has forecast 2021 to be the hottest summer season in recent years in many parts of the country. On March 24th, Delhi recorded the hottest day of the month in  76 years. In fact, 2019 was the seventh warmest year in the history of humankind after 1901.  Summers in India are becoming increasingly unbearable and cities are finding it hard to cope with heat wave related incidents. A study by scientists at IIT Gandhinagar has forecast an eight fold rise in heat wave related incidents in the country if the global community fails to check…

A year ago, Cyclone Amphan battered the eastern coast of India. This May, Cyclone Tauktae has whaled India’s western coast.  Amphan had fermented in the warm waters of the Indian Ocean and made landfall near Bakkhali, Bengal on the afternoon of May 20, 2020. Tauktae stirred forth from the cold waters of the Arabian Sea and shook the Gujarat Coast on the evening of May 17, 2021.  Both cyclones struck during a state of lockdown. Amphan was a Category 5 tropical cyclone, which refers to a ‘Very Severe Cyclonic Storm.’ Tauktae falls under Category 3 to 4, and is the…

It is utopian to imagine a world without plastic, and it has its uses. At the same time, excessive utilisation of plastic without safeguards for disposal of waste can do immense harm. It is likely to cause various health issues affecting hormones, lungs, nerves, and the overall immune system. Sometimes, it may even lead to cancer. Over the years there has been a felt need for more information on how Chennai fares with regard to microplastic pollution in the air. To find out about this, a group of researchers from Pondicherry University embarked on a mission to estimate the strength…
