COVID-19 lockdown in 2020 led to more greenery in India, says new study
The HinduImproved air quality in India during the 2020 lockdown caused an uptick in surface greenness and photosynthetic activity in plants as compared to pre-lockdown levels, a new study has revealed. The study analyses enhanced vegetation index and solar-induced fluorescence to measure changes in surface greenness and photosynthetic activity respectively in response to improved air quality in India during the 2020 lockdown. Watch | Air quality improves amid lockdown in India Results The study notes a sharp rise in both EVI and Sif – 11.54% and 16.24% – during the 2020 lockdown compared to the pre-lockdown levels. The study also uses changes in aerosol optical depth, PM 2.5, and sulphur dioxide levels to study the impact of air quality on surface greenness and photosynthetic activity.
