摘要: In this paper we describe a methodology to model the impacts of policy measures within Common Agricultural Policy (CAP) on farm production, income and prices, farmland biodiversity. Two stylised scenarios are used illustrate how method works. The effects CAP measures, such as subsidies regulations, calculated translated into changes in land use land-use intensity. These factors then biodiversity with species-based indicator 1 km scale EU27. Regionalised Impact Modelling System (CAPRI) is conduct economic analysis Dyna-CLUE (Conversion Land Use its Effects) changes. An that expresses relative species richness was for agricultural areas. illustrated baseline scenario two include specific policy. strength instruments can be linked prices incomes, one hand, effects, other – intensity connecting drivers. provides an overall assessment, but detailed impact assessment at landscape, or field level, additional would required.
