Progress in Research into Ammonia and Greenhouse Gas Emissions from Animal Production Facilities

On 1-4 June 2003, the Danish Institute of Agricultural Sciences (DIAS) hosted the International Symposium on Gaseous and Odour Emissions from Animal Production Facilities. This symposium can be considered a follow-up of the first special symposium on gaseous and odour emissions, held in 1997 in Vinkeloord, the Netherlands (Voermans and Monteny, 1997). The organizers of the 2003 symposium were Section II (Buildings) of the Commission International du Genie Rurale (CIGR), the European Association of Agricultural Engineers (EurAgEng), and the Nordic Association of Agricultural Scientists (NJF). A total of 93 participants from 22 nations got together to share the latest advancement in research and development into the important issues of gaseous emissions from animal production facilities, including odour. They presented 40 papers and 22 posters on various issues concerning gaseous emissions from animal production facilities. This paper describes the major progress in the field of ammonia, methane and nitrous oxide emissions from livestock production.
