Summary

There is a lack of results on the advantages and limitations of combining different crop diversification strategies both in time and space, which makes it difficult for famers and advisers to find relevant information for the transition towards more diversified cropping systems. A network of ten field experiments (diverIMPACTS project) was built across seven European countries, covering a range of pedo-climatic conditions and different farming systems: arable and vegetable systems under both conventional and organic management. Each field experiment tests one or several diversified cropping systems, which combine three diversification strategies with low input practices. These diversified cropping systems are compared to reference systems, which are less diversified and more dependent on external inputs. The three strategies of crop diversification are rotation, multiple cropping (growing different crop species on the same land within one growing season) and intercropping (growing different species in proximity on the same field). A diversified system includes, for example, the addition of cover crops or cash crops, such as legumes, for their expected ecosystem services, or crops for new markets (e.g hemp, lentil), the use of multiple cropping to increase productivity per year (e.g. winter barley with soybean) and intercropping (e.g. barley/pea,wheat/faba bean, oat/lupin) to increase productivity per unit of area and reduce external inputs. Expected impacts include: higher arable land productivity, diversification and increased farmer revenues through access to new markets and reduced economic risk, lower environmental impact through reduced use of pesticides, chemical fertilisers, energy and water, and improved delivery of ecosystem services, including biodiversity. The diversified cropping systems will be assessed using standardized measurements across the network and multi-criteria assessment tools. Decisions regarding the design and management of the diversified cropping systems will be recorded to support other diversification initiatives. The year 2018 is the first year of the network. This paper presents the original approach, the strategies designed in the network, and the assumptions concerning the interests to combine temporal and spatial diversification in order to improve the delivery of multiple services. This network will be a source of inspiration for other initiatives of crop diversification in Europe. The ultimate goal is to guide farmers in their transition towards more diversified cropping systems and to promote innovations by various actors at different scales (e.g. innovations regarding machinery for sowing or harvesting new sole or mixed crops, value-chains through the consolidation of new markets, new process of transformation, or adaptation of value-chains to intercropping).
