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 Mt, followed by rice at 2.1 ± 0.8 Mt, with
the losses concentrated in central and north India. On national scale,
this loss is about 12% of the cereals required every year (61.2 Mt)
under the provision of recently implemented National Food Security Bill
(September-2013) by Government of India. The nationally aggregated yield
loss is sufficient to feed 94 million people living below poverty line
in India.
