| The objective of this research is to give insights into the production, income and environmental effects of the introduction of an EU flat rate for Dutch agriculture. For this purpose, a detailed agri-environmental programming model for Dutch agriculture is used. Results of the EU flat rate scenario are compared to a reference scenario that describes agricultural production in the Netherlands in 2020. Results show that total gross margin in Dutch agriculture decreases because of the EU flat rate with 7%. The supply of starch potatoes and cow milk decreases most. Production of seed and consumption potatoes, vegetables and intensive livestock products increases slightly. This is largely due to a shift of farm payments from milk and starch potatoes... |

| Following model calculations presented in this paper he removal of the EU quota system will result in 21% more milk production in the Netherlands. Large dairy farms expand and achieve higher income levels compared to a scenario with quota continuation, as increasing scale of production and decrease of quota costs outweigh price reductions and extra manure disposal costs. Production in the category of relatively small farms, however, declines and farms in this category will leave business. Sector income will only marginally fall while production expansion will remain within the limits of present environmental policies related to manure and nutrient applications. |

| CAP reform affects employment in the agricultural sector as well as in other sectors of the regional economy through changes in regional and sectoral competitiveness and resulting re-allocation of fixed resources. However, analysis of the relationship between CAP reform and total regional employment for the EU as a whole are scarce. In this paper a rather ad-hoc method is proposed to fill this gap. Both the CAPRI model and the LEITAP model is used. Both models are linked through an econometrically estimated and scenario specific relationship between agricultural income and employment in LEITAP. LEITAP is also used to analyse the employment changes at regional level in the rest of the economy. LEITAP results are regionalized using sectoral employment shares... |

| A modelling system is presented and used to analyse the effects of EU dairy policy reform (Agenda 2000 and milk quota abolition with and without decoupled direct income payments) on Dutch agriculture and economy. The modelling system consists of a regionalised, agri-environmental, partial equilibrium, mathematical programming model of agriculture supply in the Netherlands integrated into a mixed input-output model. It was e.g. found that decoupling of direct income payments gives an extra stimulus to milk production after milk quota abolition. However, the increase in milk production is restricted by nutrient and manure policies in the Netherlands. It is also found that, although the total effect on Dutch GDP is limited, the income effects for... |

| Following the paradigm for reforming the current CAP, the first objective of this study is to give insights into the economic impact of post-2013 CAP measures at different levels of aggregation (e.g. EU, Member State and region). The post-2013 CAP measures included are directed towards income for the farmers, competitiveness, valuable areas and ecosystem services. The second objective is to analyse the impact of a scenario that combines the above mentioned post-2013 CAP measures. This study can be seen as a first attempt to quantify the transition to a CAP with more targeted measures at the European level and reveals considerable methodological and data challenges. A key finding is that the impact of the various measures is very different with regard to... |

| Analyses of the impact of European policies on agricultural change are most often based on agricultural sector models. Such models have their limitations: they cannot specify the interaction between agriculture and the rest of the economy, and their spatial dimension is usually limited. Land use simulation models, on the other hand, usually depend on other models for assessing the demand for land. The consistency of those models with the assumptions and databases of the land use model is often not examined. This article reports on a research project where the links between a macroeconomic model, an agricultural sector model and a land use model were explicitly explored in order to arrive at a consistent model chain. This integrated framework was put to the... |

| This paper identifies major future trends and driving factors and perspectives and challenges resulting from them for European agriculture and food sectors until the year 2020. The focus of the paper is an analysis of key driving forces and the provision of a well developed reference scenario under the assumption of continued CAP reform and taking into account the framework discussions in the Doha Development Round. To assess the impact of policies the paper also examines a liberalisation (no support) and regionalization (maximum support) scenario. In terms of policy options the paper shows that the structural change process in agriculture (measured in terms of agricultural share in GDP) is a long-term process that continues with or without policy changes.... |

| This paper presents a modeling system that can be used to analyze the trade off between economy and environment. It takes into account manure policy, farm structure and manure surpluses at farm level as well as the economic effects of manure surpluses at market level. The modeling system consists of two models that are linked to each other by at the one-hand manure prices and distribution of manure over different destinations and at the other hand changes in agricultural and total manure production. One model is the so-called Manure and Ammonia Model (MAM). This model calculates manure surpluses and deficits at the farm level and distribution of manure to own farm, own region, other regions, export abroad and processing at the regional level. Moreover, MAM... |

| In order to quantify the effects of a comprehensive set of policies on land use, interaction between sectors needs to be accounted for, while maintaining a high level of detail for each sector. This calls for a combination of sector specific and sector wide models. This paper describes such a modelling system, with emphasis on the linking of the models to a coherent system. Five sectors of significant importance for land use are modelled individually: Forestry, agriculture, urban land use, transport infrastructure, and tourism. All models are connected as sub-modules to an economy-wide partial econometric model. In addition, a land cover model is used to disaggregate land use down to 1km grid resolution. The linking of such a diverse set of models in a... |

| The complexity of agri-environmental economic issues is such that a model that is fully consistent at all levels of aggregation and all type of questions to be addressed is not available at the Agricultural Economics Research Institute in the Hague LEI. Such a model is probably also not feasible. At LEI this problem is solved by linking models at different scales of analysis: global economic, national economy-wide, regional agricultural, national spatial and farm levels. This linked model system enlarges scope and consistency of the analysis. The goal of the model linking, however, is not a full integration and, ultimately, simultaneous optimization of the models. Therefore, the different models of the LEI model funnel are often rather loosely linked.... |

| A modelling system is presented and used to analyse the impact of milk quota abolishment on Dutch agriculture and economy. The modelling system consists of a regionalised, agri-environmental, partial equilibrium, mathematical programming model of agriculture supply in the Netherlands integrated into a mixed input-output model. It was found that abolition of the milk quota system has large impacts on milk production and livestock numbers and composition. The latter is explained by the strict mineral and manure policies in the Netherlands; an increase in the numbers of dairy cows leaves less room for other livestock. It is also found that, although the total effect on gross value added in the Dutch economy is limited, the effects for individual industries... |
