SLI is  leading the environmental impact assessment in the IDEMA project, which has the  aim of evaluating the social, economic and environmental impacts of decoupled  agricultural support. This working paper documents development of the  environmental impact assessment module. The following issues are  addressed:
  - determination  of the key environmental issues associated with decoupling
- how  decoupling is expected to affect farmers production decisions
- how  changes in production decisions are expected to impact the agricultural  landscape and environment quality
- choice  and description of environmental indicators, and
- extension  of the AgriPoliS model (a spatial, agent based, dynamic simulation model of  regional agricultural development) to enable environmental assessment.
Environmental  analysis will be done for five representative agricultural regions in the  enlarged EU: Marginal agriculture (Jönköping and Västerbotten   Counties, Sweden),  New Member agriculture (Vysocina, Czech Republic) and Mediterranean agriculture (Marche and Calabria, Italy). The  results of the assessment will be presented in a new Working Paper to the  EU-Commission at the end of 2006.
