Integration of bio-physical and economic models to analyze management intensity and landscape structure effects at farm and landscape level

摘要: Abstract We present an integrated spatially explicit land use modeling framework, which integrates two key components of agricultural systems, the bio-physical production system and management system, by coupling bio-economic farm optimization model FAMOS[space], crop rotation CropRota, process EPIC (Environmental Policy Integrated Climate). The framework has been developed to analyze cost-effectiveness selected agri-environmental program (AEP) measures. also focus on landscape development therefore include a detailed representation elements such as fields or orchard meadows in our analysis. An indicator set represents all main environmental AEP objectives, i.e. preservation water soil resources, mitigation climate change, protection biodiversity, maintenance cultural landscapes well income support. is applied 20 farms Austrian ‘Mostviertel’ region, are from Administration Control System (IACS) European Union. measures assessed under different premium levels. implementation clearly affects quality positive way. Nitrogen rates reduced, can be sustained, becomes more diverse. increases gross margins average. However, ratios (CER) declining with increasing results indicate that improved spatial targeting.
