Core Organic Cofund project is working on the diversification of farming systems, that  might provide significant environmental and socio-economic benefits. Multi-species livestock farms are complex, and therefore difficult to characterize; however, this complexity can potentially be an advantage for developing robust animal production systems. On this issue, the Mix-Enable project presents some initial insights from estimations of their productivity across Europe in a document that can be downloaded at this LINK
