| 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... |

| The expanding global economy presents various challenges to production and environmental systems worldwide. Biosecurity provides a framework for managing the risks presented by different types of diseases and species spread by globalisation. One element of biosecurity is protection against invasive alien species (IAS). These are species spread by human actions outside their natural zones of dispersal. IAS present a threat to biological diversity at all levels and may have a negative impact on the goods and services provided by ecosystems. IAS may result in non-production and production costs. The first category includes physical impacts materialising as environmental, health and cultural costs, whereas the second category includes the subsequent economic... |

| We investigate the role that economic instruments can play in the eradication of poverty and preservation of biodiversity in agroforestry management in coffee production. Most of the world's coffee producers live in poverty and manage agro-ecosystems in regions that culturally and biologically are among the most diverse on the globe. Despite the relatively recent finding that bees can augment pollination and boost coffee crop yields substantially, the short-term revenues to be had from intense monoculture drive land-use decisions that destroy forest strips serving as habitats for pollinating insects. Our study investigates the possibility of multiple equilibria in the adoption of technology in coffee production; farmers specialize in environmentally... |

| During the past few decades, meat has increasingly become a subject of controversies relating to health and safety, environment, and animal welfare. Even though these changes in perceptions of meat are not yet visible in aggregate consumption figures, they can be observed in individual consumption patterns and as intentions to change the consumption. In this study, we examine changes in meat consumption among the Finnish consumers taking into account both stated changes in the past and intended changes in the future. Based on these changes, we identify consumer segments and investigate in which ways these segments differ from each other socio-demographically and with respect to current meat consumption and the stated reasons for the change. The latent... |

| In the European Union, the animal health and food safety strategy includes managing biosecurity along the entire production chain. Farm-level biosecurity provides the foundation for this. However, the farm-level costs of preventive biosecurity have rarely been assessed. Yet many risk management practices are in place constantly regardless of whether there is a disease outbreak or not. We contribute towards filling this information gap by studying the costs incurred in preventive biosecurity by the Finnish poultry farms. In a preliminary analysis, we find that the cost of biosecurity is some 3.55 cents per bird for broiler producers and 75.7 cents per bird for hatching egg producers. The results indicate that work-time devoted to biosecurity represents some... |
