CSIR-NBRI and International Society of Environmental Botanists (ISEB), Lucknow jointly organized a webinar on the occasion of World Environment Day today. Professor Agepati S. Raghavendra, Institution of Eminence Research Chair, School of Life Sciences, Department of Plant Sciences, University of Hyderabad, Hyderabad was the guest speaker.
While welcoming the Chief Guest, Prof. SK Barik, Director, CSIR-NBRI discussed the importance of environment day and highlighted this year’s theme ‘Ecosystem Restoration’. He said that CSIR-NBRI has been doing research work on environmental remediation and improvement for many decades.
Prof. Raghvendra, in his address on the topic "Response of Photosynthesis to Global Warming and Possible Strategies to Sustain Crop Growth" said that due to global warming, the climate of the earth has been affected the most which result in increase of greenhouse gases, global surface temperature, as seen during the past years. This ultimately affected our ecosystem by different means.
Prof. Raghavendra, while discussing the effects of increased carbon dioxide, a major greenhouse gas in earth’ atmosphere informed that due to high carbon dioxide, the process of photosynthesis in some plants are found to be increased for some time but adversely affected the the net productivity of the plants. It has also been seen their leaves and fruits lack essential minerals and nutrients, which will directly affect their consumers.
With the increase of global warming, we will have to design sustainable strategies for food security. We have to develop such plants that can tolerate rising temperature, ultra violet radiation along with increased greenhouse gases. A research strategy combining genomics, plant molecular physiology, crop breeding and integrated crop-soil-climate modeling will be very effective in tackling climate change.
Dr. RD Tripathi, Emeritus Scientist and Secretary, ISEB proposed vote of thanks in the end.
