Crop diversification practices in Europe: an economic cross-case study comparison

Crop diversification practices (CDPs) are alternative strategies aimed to achieve sustainable cropping systems and food production overcoming the agro-environmental impacts of conventional cropping systems such as monoculture. Thus, this paper aims to improve the knowledge of implementing CDPs in different European pedoclimatic regions by assessing the economic performance at the farm level. CDPs are compared with conventional cropping systems and clustered in terms of their gross margin (GM) results and variations. Farm-level assessment shows that CDPs provide positive economic results, representing an adaptive management strategy for ecological transition, without compromising economic sustainability. Particularly, the main findings show that (1) the impact of diversification depends more on crop type than on the selected CDPs, (2) most farms exhibited a low GM with low economic impact, and (3) there is a great likelihood that the CDPs facilitate the buildup of more resilient farming systems.
