In this webinar, Anne Mottet (FAO), Dong Hongmin (Chinese Academy of Agricultural Sciences) and Andrew Vanderzaag (Agriculture & AgriFood Canada) will first present global trends in livestock production and methane emissions, and discuss methods of monitoring, mitigation and accounting. A new approach for estimation of methane emissions from manure management via measurements and an empirical model will then be introduced. This methodology was investigated in the ERA-Net project M4Models and will be presented by Søren O. Petersen and Paria Seefedpari.
