Tropospheric ozone, which has been increasing in recent years, has a strong oxidizing power and is said to have a negative impact on crops, especially on crop yields. This paper clarifies the effects of changes in tropospheric ozone concentration associated with climate change mitigation measures on food consumption and the population at risk of hunger through changes in crop yields, based on climate scenarios. As a result, the global population at risk of hunger decreased by 474, 000 under the scenario corresponding to the 1.5 degree target. By region, large decreases were seen in the Middle East and other parts of Asia, which are still facing severe hunger. It can be said that the secondary benefits brought about by the reduction of these tropospheric ozone concentrations will serve as incentives for the introduction of climate change mitigation measures centered on developing countries.
