“Delhi air quality has never met WHO criteria,” says Dr T.K. Joshi, Director, Centre for Occupational and Environmental Health (COEH), Maulana Azad Medical College and part of the 16-member Delhi Pollution Control Committee (DPCC) set up by the government. “It is even more stressed now and is expected to worsen”. The worsening mostly happens during November-December, and lingers on, largely due to paddy stubble burning by farmers in Punjab and Haryana to get their fields ready for the winter wheat sowing. Now, with satellite remote sensing data from the Indian Agriculture Research Institute (IARI) showing  a five-fold increase in the number of farm…

Blessings come in many forms. For the citizens of IC Colony, Borivali West, it is the chirping of birds, waking up to their melody, watching their daily routine and witnessing different species inhabiting amidst them. Before the lockdown, only crows, pigeons, and a few other birds were visible, but lockdown brought a welcome change. Lockdown restricted human movement and this encouraged birds to come out from their hidden spots, fly freely and enjoy the pollution-free environment. “Due to the lockdown, I could spend more time watching the birds around. It helped me remain calm. Bulbuls and mynahs frequently come to…

Tree walks and nature trails are a great way to connect with natural surroundings. Delhi’s green spaces offer ample opportunity for tree enthusiasts, and the constant monitoring has also led to better chronicling of the flowering cycles of different tree species. Delhi has good green cover compared to many other national capitals, says heritage expert and author Vikramjit Singh Rooprai. Some of the best-preserved green spaces are Sanjay Van, Sundar Nursery, Northern Ridge, Central Ridge, Muradabad Pahari in Vasant Vihar, Aravalli hills, Sultan Ghari Park, Yamuna Biodiversity Park, and Mehrauli Archaeological Park.

During the virtual celebration of World Environment Day on June 5th this year, Prakash Javadekar, India’s minister for environment, forests and climate change, launched the Nagar Van project. The scheme aims to create urban forest cover in 200 cities across the country in the next five years. Oddly enough, in 2016 Javadekar launched the exact same scheme at a commemorative function at the Sanjay Gandhi National Park in Borivali, Mumbai. None of the experts The Third Pole’s correspondent spoke to were aware of any progress on the scheme. Nor is any government data available on what goals were achieved on planting “200 city forests” between 2016…

The rich nectarine blooms hanging from indigenous trees adds to the beauty of several streets in Chennai. What often goes unnoticed, though, is the number of butterflies that are seen fluttering around the plants. Amid the hustle and bustle of a megacity like Chennai, it may be hard to believe that a sight like this is so common. Wherever there is lush canopy, we can see butterflies in the dozens. The city has lost acres of green cover to infrastructural projects and natural disasters. Yet, the urban jungle is home to about 150 species of butterflies.  Throughout the city, Common…

Traditionally, Bengaluru’s lakes stay dry for a couple of months, and fill up during the monsoons. This made it easier for potters, brick makers and farmers to collect silt from lakes. But due to climate change, rapid urbanisation and unplanned development, more lakes have been drying up for longer periods of time. An article by Times of India states that “According to BBMP, about 50% of the lakes have water less than half of their holding capacity. Some of them have gone dry and in others, the water level is fast depleting”. Sowl Kere, Kannamangala lake, Arakere, Sarakki, and Yelahanka…

Greater Chennai Corporation has kickstarted the vertical gardens project under 14 selected flyovers in Chennai. According to a news report, the spaces under the flyovers at IIT-M traffic junction, North Usman Road flyover, Mint, Doveton, Pantheon Road, Perambur, Mahalingapuram, Usman Road, TTK Road, Kauvery hospital, Royapettah high road, G P Moopanar flyover, LB Road and Gandhi Mandapam will get vertical green cover.  This is a utilitarian move aimed at better use of public spaces in order to mitigate carbon emissions on Chennai roads. GCC is following in the footsteps of developed cities such as Singapore that has made the concept…

According to legend, King Solomon had a brief encounter with a “valley of ants” and his admiration for them led him to value all life forms. The resilience of ants is seen in the way they quickly adapt to changing conditions of the environment and their ability to colonise new habitats. It is further evident in the fact that there is practically no habitat, including the most developed cities, where there are no ants. Little is known about the diversity of ants in Chennai and there is a dearth of scientific studies on this. However, from what little is known,…

Flanked by the Outer Ring Road, where unceasing traffic spews noxious fumes, and a concreted canal where heaps of plastic float amid sewage, the Hennur Lake Biodiversity Park is an incongruous speck of green in a wide swath of concrete. And for a few slender loris individuals, it is an unlikely home. As implausible as it may seem, gray slender lorises (Loris lydekkerianus) have clung to life while the city’s concrete-scape has cornered them into this 34-acre park. At least 4-5 individuals of the beady-eyed, small, elusive primate species has been spotted in the canopies of the park. Surveys conducted between…

Mangrove Action Project recently announced the winners of their 2020 Mangrove Photography Awards.
