1 Swedish production of organic grain legumes for food insights from research and practice, Swedish University of Agricultural Sciences, Department of Biosystems and Technology, Alnarp, Sweden Per Modig, Fagraslätt farm / Swedish Rural Economy and Agricultural Society, Kristianstad, Sweden

3 Potential to replace part of the meat consumption in Sweden with domestic grain legumes? 70% of Swedens agricultural land is used for animal feed production More grain legumes could be grown in Sweden, e.g. pea, faba bean, Phaseolus beans, lupins, lentil, soybean. Photo: Pamela Yah Konfor

4 Protein supply, comparing current meat consumption with a scenario that domestic grain legumes replace imported meat g protein capita -1 day current replace import legumes chicken pork beef Calculations based on data in Hallström et al. (2014). Food Policy 47,

5 Protein supply, comparing current meat consumption with a scenario that domestic grain legumes replace imported meat This replacement requires a per-capita consumption of about 110 g cooked beans, peas or lentils per day. Photo: G. Carlsson

6 Climate impact, comparing current meat consumption with a scenario that domestic grain legumes replace imported meat kg CO 2 -eq. capita -1 year current replace import legumes chicken pork beef * * Assuming greenhouse gas emissions corresponding to 1,3 kg CO 2 -eq. per kg dry GL.

7 Land use: the replacement requires about ha for increased Swedish grain legume cultivation Assuming average GL yield yield of 3 ton/ha, containing 26 % protein 1200 Blue bars: current land use in Swedish agriculture (Swedish board of Agriculture / Statistics Sweden) Thousands ha Land in Sweden required for grain legume cultivation to replace imported meat (green part of the bar). Land (outside Sweden) required for the production of imported meat. 0 Temporary grasslands, forage crops Cereals Pastures, meadows Oilseeds Sugar beet, potato Field vegetables, niche crops Grain legumes Land saving

8 Increased grain legume cultivation cropping system diversification Reduced need for N fertilization and pesticides in conventional production New opportunities for grain legume production on organic farms without animals Photos: G. Carlsson

9 Yield stability in organic grain legume production Abundant weed growth in fields with organic cultivation of lupins, faba beans and lentils (photos: G. Carlsson).

12 Why not more intercropping? Despite the mentioned benefits, intercropping for production of mature grains is rarely adopted by Swedish farmers Technical challenges for cultivation and harvesting Photos: E.S. Jensen

13 Focus on Intercropping in Organic Legumes (FIOL) Ongoing research aiming to identify problems, market opportunities and technical solutions for Swedish organic grain legume production.
