Observe the trees around you with SeasonWatch

Using citizen science to track the patterns of emergence and maturation of leaves, flowers and fruits of Indian tree species.

Climate change is experienced in the form of erratic, unpredictable and extreme weather changes in the various seasons. This is impacting the periodic appearance of leaves, flowers, and fruits on the seasonal trees around us. Observing these changes regularly can give an insight into climate change’s impact on biodiversity in India. Since trees are the basis of all life, including ours, understanding the impact of climate change on trees is imperative.

For over a decade, SeasonWatch is leading a citizen science project following the patterns of emergence and maturation of leaves, flowers and fruits (“phenology”) on common tree species of India. Seasonal phenology of trees can be affected by larger problems such as climate change and serve as reliable indicators of the same.

Contribution from the citizens in observing trees and collecting data can be an efficient way to collect large amounts of seasonality information from all over the country. The upcoming quarterly tree festival – March Tree Festival 2023 – is one such way of reaching out to more people and encouraging them to participate.

The competition has three challenges to make things exciting:

  • Observing 100 trees in 10 days
  • Collecting data on as many individuals as possible of 5 tree species with red/orange flowers
  • 8 tree species that are likely to sprout new leaves in March.

Contributors with the highest number of trees observed in the different challenges will win prizes.

“Tree watching in Kashmir is definitely a unique activity. It will clone the facts and changes of spring into education and research for sustainability”, says Akhter Hussain, Society for Env. Edu. & Development (SEED)

“The eye easily wanders to all that has lush, new and fresh leaves and the colours are indeed striking. As I consciously began looking at these trees, I realised how beautiful the early months of summer are. I wonder why I didn’t have the eye to see these things all these years”, says Suhirtha Muhil M, Project Manager – SeasonWatch

Why the national programme for clean air failed a gasping Mumbai

Mumbai has seen an alarming decline in air quality. A look at the limited impact of the National Clean Air Programme on mitigating pollution.

October 2023 was a shocker for Mumbai. The coastal city has historically recorded lower AQI levels as compared to Delhi, which is notorious for its poor air quality. But the tables turned in October 2023, with AQI in Mumbai reaching dangerously high levels of up to 300, surpassing Delhi for several days. This led to a slew of respiratory ailments, more so among the vulnerable populations. PM2.5 levels have, in fact, seen a consistent increase in Mumbai over the past three years. Dr Jui Mandke, a paediatric surgeon practising in Mumbai, says, โ€œIn October 2023, we encountered the maximum number…
