Profile

Biography

Chubamenla Jamir started a PhD in the Department of Environment and Geography in October 2007. She is based at the Stockholm Environment Institute-York. Prior to starting the PhD she has done 3 ½ years of research at the Jawaharlal Nehru University, New Delhi, India. Her research looked at the effect of ground level ozone and ultra violet radiations on food crop production.

Title:  Impact of ground level Ozone on food crop production in India

Supervisor:  Dr. Lisa Emberson

TAC:  Prof. Mike Ashmore (Chair), Dr. Jim Smart, Dr. Jennie Barron (SEI-York)

Funding source:  Government of India

Description of Thesis

My research focuses on the impact of ground level ozone on food crop production in South Asia (with special focus on India).

High concentrations of ozone (O3) have been reported in the Indo-Gangetic plains, the most important crop growing region in South Asia. Experimental studies have reported that the current day surface O3 concentrations in this region frequently result in yield losses of up to 30% for sensitive crops (e.g., wheat, rice, legumes). Future global emission projections suggest that, even with implementation of current emission reduction legislation, South Asia may become one of the most O3 polluted regions of the world. This suggests that O3 may pose a potential threat to future food security in South Asia. The region’s economy is agriculture based with more than 70% of the population still depending on agriculture for their livelihood. Therefore any threat to agriculture will have serious implications on the welfare of the people.

The main objectives are:

1. To estimate the impact of ozone on food crop production in India based on the existing ozone risk assessment methodologies
2. To parameterise the flux based ozone impact assessment model for crop cultivars grown in India.
3. To develop a partial equilibrium model that would determine the effect (in terms of economic loss) of ozone induced crops production losses on the producers and consumers in India.
4. To study how the Biotechnological advancements in the region would influence the sensitivity of food crops to ozone.
