Är det samhällsekonomiskt lönsamt att odla soja i Sverige?

Sammanfattning: The aim of this study was to analyze if soya framing would be nationally-economical to produce with a vertical hydroponic system, compared to being imported from Brazil. With the intention to study the production cost and climate impact effects of local production. The costs and benefits of the culture have been analyzed and compared to imported soya from Brazil. In order to answer the questions of the study, climate effects have been converted into economic values. Information about the Brazil soya is based on different LCA of the production and effect of land change. Since soya has not been produced with the help of a vertical hydroponic system in Sweden, different assumptions have been made to complete the different calculations. Different benefits of local production in Sweden have been categorized as benefits and compared to the actual cost of the project. The result of the comparison has been interpreting over a period of 50 years to make it possible to see the effect over time. With the available information, this study has reached the result that this form of culture is not sustainable socially-financially or climatically. Regarding the results, the factor that stands out the most is the energy use and cost from the lightning. It’s important to take considerations of the fact that the information regarding lights needs more research and specific testing on soya.
