Última RECOVERING LOCALIZED INFORMATION ON AGRICULTURAL STRUCTURE UNDERLYING DATA CONFIDENTIALITY REGULATIONS - POTENTIALS OF DIFFERENT DATA AGGREGATION AND SEGREGATION TECHNIQUES AgEcon Gocht, Alexander; Roeder, Norbert. The modelling and information system RAUMIS is used for policy impact assessment to measure the impact of agriculture on the environment. The county level resolution often limits the analysis and a further disaggregation at the municipality level would reduce aggregation bias and improve the assessment. Although the necessary data exists in Germany, data protection rules (DPR) prohibit their direct use. With methods such as the Locally Weighted Averages (LWA), and with aggregation singling production activities into larger groups of activities, the data at the municipality level can be made publicly available. However, this reduces the information content and introduces an additional error....

Ano: 2010 URL: http://purl.umn.edu/93975 Kosten-Wirksamkeitsanalyse unterschiedlicher Randstreifenbreiten in einem Uferrandstreifenprogramm zur Reduktion des Risikos chemischer Pflanzenschutzmittel---Entwicklung und Anwendung eines modellbasierten Indikators im Agrarsektormodell RAUMIS AgEcon Sieber, Stefan; Holm-Muller, Karin; Gutsche, Volkmar; Kreins, Peter. A variety of agri-environmental instruments can be used to combat water pollution by pesticides in agriculture according to the regulation EC 1257/1999. The chosen policies should be politically feasible and capable to prevent external effects cost-effectively. One possible policy instrument for Germany is the implementation of nation-wide buffer strip programs. This paper aims at evaluating the cost-effectiveness of alternative strip widths. Therefore an indicator is developed that reflects the impact of plant protectant use on aquatic ecosystems. This indicator is used to compute reductions in pesticide impact of different strip widths and the agricultural opportunity costs computed by the agri-environmental policy-information-system RAUMIS.

Ano: 2010 URL: http://purl.umn.edu/93938 Salvage the treasure of geographic information in Farm census data AgEcon Gocht, Alexander; Roder, Norbert. In Germany, since several decades the RAUMIS modelling system is applied for policy impact assessments to measure the impact of agriculture on the environment. A disaggregation at the municipality level with more than 9.600 administrative units, instead of currently used 316 counties, would tremendously improve the environmental impact analysis. Two sets of data are used for this purpose. The first are geo-referenced data, that are, however, incomplete with respect its coverage of production activities in agriculture. The second set is the micro census statistic itself, that has a full coverage, but data protection rules (DPR) prohibit its straightforward use. The paper show how this bottleneck can be passed to obtain a reliable modelling data set at...
