An integrated simulation model to evaluate national policies for the abatement of agricultural nutrients in the Baltic Sea AgEcon
Hyytiainen, Kari; Ahtiainen, Heini; Heikkila, Jaakko; Helin, Janne; Huhtala, Anni; Iho, Antti; Koikkalainen, Kauko; Miettinen, Antti; Pouta, Eija; Vesterinen, Janne.
This study introduces a prototype model for evaluating policies to abate agricultural nutrients in the Baltic Sea from a Finnish national point of view. The stochastic simulation model integrates nutrient dynamics of nitrogen and phosphorus in the sea basins adjoining the Finnish coast, nutrient loads from land and other sources, benefits from nutrient abatement (in the form of recreation and other ecosystem services) and the costs of agricultural abatement activities. The aim of this study is to present the overall structure of the model and to demonstrate its potential using preliminary parameters. The model is made flexible for further improvements in all of its ecological and economic components. Results of a sensitivity analysis suggest that...

Does Scale Matter? Cost Effectiveness of Agricultural Nutrient Abatement When Target Level Varies AgEcon
Iho, Antti.
Agricultural production is facing high requirements on nutrient runoff reduction. Furthermore, the reductions should by done efficiently. For instance, the European Water Framework Directive calls for cost-effectiveness from schemes of measures to fulfill the target of good water quality in European river basins. In this paper we analyse the implications of target level variation on efficiency properties of agricultural phosphorus abatement. We analyse the robustness of cost-effectiveness as the scheme of measures is adopted from another, identical river basin with different target level on total phosphorus abatement. We find that even between homogeneous regions the cost-effective scheme of measures is unique for all target levels of reduction, and that...

Dynamically Optimal Phosphorus Management and Agricultural Water Protection AgEcon
Iho, Antti; Laukkanen, Marita.
This paper puts forward a model of the role of phosphorus in crop production, soil phosphorus dynamics and phosphorus loading that integrates the salient economic and ecological features of agricultural phosphorus management. The model accounts for the links between phosphorus fertilization, crop yield, accumulation of soil phosphorus reserves, and phosphorus loading. It can be used to guide precision phosphorus management and erosion control as means to mitigate agricultural loading. Using a parameterization for cereal production in southern Finland, the model is solved numerically to analyze the intertemporally optimal combination of fertilization and erosion control and the associated soil phosphorus development. The optimal fertilizer application rate...
