This bottom-up modeling study, supported by emission inventories and
crop production, simulates ozone on local to regional scales. It
quantifies, for the first time, potential impact of ozone on
district-wise cotton, soybeans, rice, and wheat crops in India for the
first decade of the 21st century. Wheat is the most impacted crop with
losses of 3.5 ± 0.8 million tons (Mt), followed by rice at 2.1 ± 0.8 Mt,
with the losses concentrated in central and north India. On the
national scale, this loss is about 9.2% of the cereals required every
year (61.2 Mt) under the provision of the recently implemented National
Food Security Bill (in 2013) by the Government of India. The nationally
aggregated yield loss is sufficient to feed about 94 million people
living below poverty line in India.
