Última How much can be gained by optimizing nutrient abetment spatially – Cost – efficiency comparison of non – point arable loads from different Finnish watersheds AgEcon Helin, Janne; Tattari, Sirkka. Targeting has become the buzz word in the national agri-environmental policy reform in Finland. It is generally accepted that more environmental benefits could be reaped by implementing environmental protection measures where they have the biggest positive impact. However, considering one of the main environmental problems in Finland resulting from agriculture, eutrophication, the identification of first-best policy or even the biggest contributors among the diffuse nutrient sources remains as a considerable challenge. The model developed in this study aims to demonstrate how the agricultural nutrient load potential can be calculated in a way which supports the identifying of cost-efficient abatement policies. We use metamodeling of dynamic nutrient load...

Ano: 2010 URL: http://purl.umn.edu/109381 Does geography matter in nutrient abatement? Bioeconomic model of heteregoneus farm nutrient loads AgEcon Helin, Janne. Economists often rely on stylised models for analysis of environmental policies. This study demonstrates that abstracting from soil and topography can have profound effect on marginal abatement costs of nutrient loads. By extending earlier bioeconomic models to represent heterogeneous soils and slopes, it is possible to show that targeting the abatement methods on high load risk areas allows low cost reduction. Ignoring the heterogeneity can lead to significant overestimates of the abatement costs and hence to misleading policy recommendations. The results hold even for relatively Flat areas, such as the watershed of River Kalajoki, for which the model was applied to.

Ano: 2009 URL: http://purl.umn.edu/51693 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...

Ano: 2009 URL: http://purl.umn.edu/49896 Environmental protection of agriculture -clash of policies? AgEcon Helin, Janne. Agricultural primary production is extensively influenced by policies and regulation. On the level of European Union the common agricultural policy (CAP), frames the production environment. This study analyses the conflict of environmental and income policies in the context of CAP reform, eutrophication, the Water Framework Directive and Finnish policies. As targets of the policies do not coincide and often conflict, the environmental problems of farming have not been solved in the past decades. The comparative analysis is conducted quantitatively under static non-linear optimisation framework of representative farms of cereal and milk production regions of Finland. The results indicate that the decoupling of subsidies from production has enabled more...

Ano: 2008 URL: http://purl.umn.edu/6468 Abatement costs for agricultural nitrogen and phosphorus loads: a case study of South-Western Finland AgEcon Koikkalainen, Kauko; Laukkanen, Marita; Helin, Janne. Designing efficient agri-environmental policies for agricultural nutrient load reductions calls for information on the costs of emission reduction measures. This study develops an empirical framework for estimating abatement costs for nutrient loading from agricultural land. Nitrogen abatement costs and the phosphorus load reductions associated with nitrogen abatement are derived for crop farming in southern Finland. The model is used to evaluate the effect of the Common Agricultural Policy reform currently underway on nutrient abatement costs. Results indicate that an efficiently designed policy aimed at a 50 % reduction in agricultural nitrogen load would cost $25 to $28 million, or $1995 to $2197 per farm.
