Dr. Yam Gaihre serves as the IFDC focal person in Nepal and coordinates field research activities in Asian countries, including Nepal, Bangladesh, and Myanmar. He liaises with the national agriculture research and extension system (NARES) for research partnership and capacity building.

Gaihre has more than 15 years of experience in soil fertility- and fertilizer-related research in a rice-based cropping system. His expertise lies in soil fertility and fertilizer management, carbon and nitrogen dynamics in a rice-based cropping system, greenhouse gas (GHG) emissions measurement and mitigation of GHGs through efficient fertilizer, water and residue management, and climate-smart agriculture. He has worked on several research and development projects in Bangladesh, Myanmar, Philippines, and Nepal.

Before joining IFDC, Gaihre worked at the Nepal Agricultural Research Council (NARC) during 2004-2013 and as a post-doctoral fellow at the International Rice Research Institute (IRRI), Philippines, from 2012 to 2013. 

Gaihre holds a doctorate in soil science from the University of the Philippines. He has published more than 25 peer-reviewed scientific papers.
