Evaluation and Spatialization of GAseous Emissions from farmyard manure Management (ESEGA): from inventory to testing of gaseous emissions reduction technologies

Abstract

An original approach of construction of an information system applied to the assessment of NH3, N2O and CH4 gas emissions at the various stages of livestock manure management based on the mass-flow concept is herein presented. The tool ESEGA corresponds to the combination of a relational database dedicated to calculations and a Geographical Information System (GIS) in order to provide dynamic cartographies of the results. This tool of decision-making aid appears well adapted for a realistic assessment of the gaseous emissions and for the evaluation of mitigation strategies, with single or combined techniques. The evolutionary possibilities of this tool enable to consider new applications and uses at several space scales.
