The GRA Manure Management Network (MMN) is a global forum for scientists focused on reducing greenhouse gas emissions from livestock production and increasing the nutrient use efficiency of manures. Manure management is the handling, storage and disposal of urine and feces from livestock, other than the manure deposited directly onto pastures by grazing animals. MMN areas of research interest include: Improving our understanding of drivers of greenhouse gas emissions from manuresDeveloping a directory of mitigation strategies that can be applied…

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.
