Última Farm Entry Policy and Its Impact on Structural Change Analysed by and Agent-based Sector Model 31 Mack, Gabriele; Mohring, Anke; Zimmermann, Albert; Gennaio, Maria-Pia; Mann, Stefan; Ferjani, Ali. The Swiss agent-based model (SWISSland) claims to depict as realistically as possible the 50 000 family farms comprising the whole of Swiss agriculture in all their heterogeneity as regards farm and cost structures as well as farm decision-making behaviour and interactions, with the aim of improving the simulation and forecasting of structural change in agriculture. With the linking of different methods and recorded data, there is a marked increase in the quality of the assessment of policy consequences. Simulations are shown for policy measures which affect only farm entry by cutting socially motivated direct payments for young operators.

Ano: 2011 URL: http://purl.umn.edu/114374 Modelling structural change in the agricultural sector – An Agent-based approach using FADN data from individual farms 31 Mohring, Anke; Zimmermann, Albert; Mack, Gabriele; Mann, Stefan; Ferjani, Ali; Gennaio, Maria-Pia. The development of multi-agent models for agriculture has allowed the inclusion of farm decision-making behaviour and interactions in the simulation of smaller agricultural regions. Important methodological impact for this has come in particular from scientists from Germany. Currently under construction, the SWISSland model claims to depict as realistically as possible the 50,000 family farms comprising the whole of Swiss agriculture in all their heterogeneity as regards farm and cost structures as well as farm decision behaviours, with the aim of improving the simulation and forecasting of structural change. This paper describes methodological aspects in the formation of the agent population by combining various data sources such as accounting and spatial...

Ano: 2010 URL: http://purl.umn.edu/61094 Construction and Application of an LP Farm Model with an Integrated Life Cycle Assessment for the Determination of Sustainable Milk Production Systems 31 Mohring, Anke; Zimmermann, Albert. The increasingly stringent conditions underlying Swiss dairy production demand sustainable milk production systems that are economically optimized but also meet the ecological requirements of society. To determine such systems, a comparative-static LP model was constructed at farm level. Realistic production systems are reproduced in the model by means of binary variables. An Life Cycle Assessment (LCA) was integrated into the model to determine the environmental impacts of the farm. To this effect, the internal farm influences on production are illustrated in detail. An initial application of the model, in which a comparison of different income-optimized production systems was carried out, revealed some goal conflicts between economics and ecology....

Ano: 2005 URL: http://purl.umn.edu/24714 Combination of the Swiss agrarian sector model SILAS-dyn with the life cycle assessment tool SALCA 31 Zimmermann, Albert. The agricultural sector model SILAS-dyn has been used by Agroscope ART for 10 years for the political advisory of the Swiss agricultural administration. To evaluate the environmental effects of different policy scenarios, a LCA module has been developed, connecting a hierarchical linkage to an existing LCA calculating tool. This lowers the formulation input and simplifies the adaptation of updated environmental models. The results of four scenarios show, through the example of energy use as an environmental impact, that indirect effects, such as energy use in the context of imported concentrates, can influence conclusions significantly. The scenario suggesting an increase of fertiliser prices does not change the results significantly, whereas higher energy...

Ano: 2008 URL: http://purl.umn.edu/6603 Multidisziplinäre Agentendefinitionen für Optimierungsmodelle 31 Mohring, Anke; Zimmermann, Albert; Mack, Gabriele; Mann, Stefan; Ferjani, Ali; Gennaio, Maria-Pia. Mit der Entwicklung von Multiagentenmodellen für die Landwirtschaft konnten betriebliche Entscheidungsverhalten und Interaktionen in die Simulation von kleineren Agrarregionen einbezogen werden. Wichtige methodische Impulse dazu kamen insbesondere von Wissen-schaftlerinnen und Wissenschaftlern aus Deutschland. Das sich im Aufbau befindende Modell SWISSland erhebt den Anspruch, die 50 000 Familienbetriebe der gesamten Schweizer Landwirtschaft in ihrer Heterogenität bezüglich Betriebs- und Kostenstrukturen sowie Verhal-tensweisen möglichst realitätsnah abzubilden, mit dem Ziel, die Simulation und Prognose des Strukturwandels zu verbessern. Dieser Beitrag beschreibt methodische Aspekte bei der Bil-dung der Agentenpopulation unter Verwendung verschiedener...
