Evaluation of various ÖPUL measures with regard to the reduction of greenhouse gas emissions, in particular nitrous oxide
Abstract
In this study we will examine the effect of specific ÖPUL measures in order to reduce GHG emissions. For the calculation we apply the process based model LandscapeDNDC. The main focus will be on nitrous oxides (N2O) emissions since most of total national N2O emissions origin from agricultural soils. In detail, the following questions will be considered: • How much do N2O emissions decrease when the fertilizer intensity (i.e., nitrogen supply) is reduced? Do N2O emissions decrease disproportionately with less nitrogen fertilizer? • What is the difference between N2O emissions in intensively managed, conventional and organic arable and grassland soils? • Which effects are gained by the UBB (Environment-friendly and Biodiversity-friendly farming) measures in crop rotations? This comparison of the different management measures in a few regions serves as a clarification for future research projects where the effects of Austria-wide land use and land use changes on the basis of model calculations and measurements are to be examined in terms of their climate effect.
