Última Modelling N2O emissions from organic fertilisers for LCA inventories Organic Eprints Meier, Matthias S.; Schader, Christian; Berner, Alfred; Gattinger, Andreas. Apart from mineral fertilisers, organic fertilisers act mainly via the soil C-N pool in order to provide available nitrogen to plants. This different mode of action is not reflected so far in the current IPCC N2O emission model. Here we propose a simple model to calculate N2O emissions from organic fertilisers and plant residues. It considers the long-term immobilisation of N within stable organic matter in the soil as well as the mineralisation of additional N from the soil pool. A first test with field data showed reliable simulations of measured N2O emissions. By comparing values generated by our model with values generated by the IPCC model we show that the IPCC model may overestimate emissions from organic fertilisers. Therefore, within LCA...

Agriculture is considered to be one of the main drivers for worldwide biodiversity loss but the impacts of agricultural production on biodiversity have not been extensively considered in Life Cycle Assessments (LCAs). Recent realisation that biodiversity impact should be included in comprehensive LCAs has led to attempts to develop and implement methods for biodiversity impact assessment. In this review, twenty-two different biodiversity impact assessment methods have been analysed to identify their strengths and weaknesses in terms of their comprehensiveness in the evaluation of agricultural products. Different criteria, which had to meet the specific requirements of biodiversity research, life cycle assessment methodology, and the evaluation of...

Ano: 2016 URL: http://orgprints.org/33419/1/gabel-etal-2016-JEnvironManagment_Vol181-p249-260.pdf Quantification of the effectiveness of greenhouse gas mitigation measures in Swiss organic milk production using a life cycle assessment approach Organic Eprints Schader, Christian; Jud, Katja; Meier, Matthias S.; Kuhn, Till; Oehen, Bernadette; Gattinger, Andreas. Quantitative assessments of the effectiveness of GHG mitigation measures at farm level are scarce. Hence, the aim of this study was to quantify the GHG mitigation potential of selected measures on two typical organic farms in Switzerland. We built a single-farm model which enabled us to calculate the GHG emissions and energy consumption at farm level using a life cycle assessment approach. The model was used to calculate the effects of 13 different mitigation measures on a Swiss organic dairy and a Swiss organic mixed farm. At the dairy and mixed farm, respectively, 5.4% and 5.5% of mitigation in relation to the farms’ total GHG emissions could be realized by technical means and 15.4% and 12.9% with agronomic measures. Technical measures include the use of... Tipo: Journal paper Palavras-chave: Air and water emissions. Ano: 2014 URL: http://orgprints.org/26227/1/Schader_et_al_2014_JCP.pdf Simulating evolutionary responses of an introgressed insect resistance trait for ecological effect assessment of transgene flow: a model for supporting informed decisionmaking in environmental risk assessment Organic Eprints Meier, Matthias S.; Trtikova, Miluse; Suter, Matthias; Edwards, Peter J.; Hilbeck, Angelika. Predicting outcomes of transgene flow from arable crops requires a system perspective that considers ecological and evolutionary processes within a landscape context. In Europe, the arable weed Raphanus raphanistrum is a potential hybridization partner of oilseed rape, and the two species are ecologically linked through the common herbivores Meligethes spp. Observations in Switzerland show that high densities of Meligethes beetles maintained by oilseed rape crops can lead to considerable damage on R. raphanistrum. We asked how increased insect resistance in R. raphanistrum – as might be acquired through introgression from transgenic oilseed rape – would affect seed production under natural herbivore pressure. In simulation experiments, plants protected... Tipo: Journal paper Palavras-chave: Cereals; Pulses and oilseeds Environmental aspects Regulation.

Organic Eprints Meier, Matthias S.; Stoessel, Franziska; Jungbluth, Niels; Juraske, Ronnie; Schader, Christian; Stolze, Matthias. Comprehensive assessment tools are needed that reliably describe environmental impacts of different agricultural systems in order to develop sustainable high yielding agricultural production systems with minimal impacts on the environment. Today, Life Cycle Assessment (LCA) is increasingly used to assess and compare the environmental sustainability of agricultural products from conventional and organic agriculture. However, LCA studies comparing agricultural products from conventional and organic farming systems report a wide variation in the resource efficiency of products from these systems. The studies show that impacts per area farmed land are usually less in organic systems, but related to the quantity produced impacts are often higher. We reviewed 34...
