Biodiversiteetin ja vesistönsuojelun yhdistäminen taloudellisessa optimointimallissa
Janne Helin

Agriculture is a significant source of excess nutrients in both inland waters and the sea. This negative externality must be weighted with the provision of positive public good, biodiversity, since agriculture   sustains habitats for many species. This study combines the biodiversity protection with water protection at a catchment scale and provides an optimizing tool for analysing the effect of spatial dependencies on multifunctional agriculture.  We show a synergetic optimal solution for vegetated buffer zones given heteregenous landscape classification of Lepsämänjoki sub-catchment.  Including the benefits from biodiversity will steer the land allocation even when the biodiversity prices are relatively low since there is less variation in spatial distribution of nitrogen load at the sub-catchment level.
