Bjoern Ole Sander

Ole is a scientist in IRRI’s climate change research group with a focus on greenhouse gas (GHG)mitigation technologies. He joined IRRI in January 2010 as a Collaborative Research Scientist with Dr. Reiner Wassmann.

Ole analyzes the GHG balance of different cropping systems in Vietnam and the Philippines. He evaluates different mitigation options through water-, fertilizer and crop residue management and identifies suitable conditions to support dissemination of mitigation technologies. Especially the water saving method AWD (alternate wetting and drying) offers huge potential to reduce methane emissions and Ole works with different stakeholders in Vietnam, Bangladesh and the Philippines to foster implementation of this climate smart farming practice. Read more >>
