    Circular economy and nutrient recycling have become central aims of agricultural development domestically and internationally. In Finland the enhancement of nutrient recycling is hindered by the areal dividedness of agricultural production. The high animal densities in West-Finland produce more manure nutrients than the area can sustain whereas in the South-Finland the Uusimaa region is dependent on mineral phosphorus fertilizers as there isn’t enough manures in the region. Also the unutilized grasslands have potential for increasing efficient silage and energy grass production, which enables nutrient recycling through biogas or livestock production. In this thesis the agricultural production structure of Uusimaa is approached from the perspective of the regional feed production and the feed production potential as an enabler of more balanced regional crop-livestock production. Simultaneously the regional nutrient recycling and livestock product self-sufficiency enhances. The method used is MFA (material flow analysis) which is applied to the case study area of the Mäntsälä municipality with results scaled up to the rural areas of Uusimaa County. The materials were based on annual statistics of Finland’s production structure and agricultural production. The Mäntsälä municipality’s nutrient balance of nitrogen and phosphorus, the average yields and self-sufficiency in livestock products were analyzed. Three alternative scenarios were introduced to analyze the possibilities of increasing livestock production, enhancing nutrient recycling and attaining livestock product self-sufficiency. The case area has remarkable potential for livestock production increases. With these increases the cereal dominated region gains the possibility of replacing a majority of mineral fertilizers with the manures. Simultaneously, the municipal production can come close to meeting the municipal consumption. These additions of livestock can be carried out without changes in crop areas, but then the livestock production would depend on imported mineral and protein feeds. Also the increases in protein feed needs can be met by transforming the needed areas from cereal areas. In addition the unutilized grasses provide a potential for enhancing the areal silage production. The case study area can’t meet the areal consumption of livestock produce without using the expanse of the present cereal cultivation areas. The results suggest that Uusimaa and its surrounding rural regions have great potential for increasing livestock production and enhancing the nutrient recirculation, whereas the regional consumption cannot be met with the regional production. To enhance sustainable agroecosystem in Finland changes in production structure, way of production and the consumption patterns of citizens are needed.
