Description

The air pollution and greenhouse gas emission problem has been exacerbated in India due to large population increase and rapid economic growth. The Indo-Gangetic Plains of Northern India, one of the most fertile regions of the world, has become one of the most polluted regions. The region has emerged as a ‘hot spot’ for air pollution, especially ozone (O3), threatening food-grain production. The air quality data show large parts of India suffering from high pollution load. Unfortunately, O3 monitoring is still in its infancy. There are reports of O3-caused yield and biomass losses in crops ranging between 10% and 51%, offsetting a significant portion of the Gross Domestic Productivity growth rate. There are no O3 experiments conducted with Indian tree species, but the crop losses suggest that O3 may have a deleterious impact also in long-lived trees in the Indian area. There is a critical need to study how O3will impact trees and forest ecosystems.
