Among agroforestry systems, a particular form of intercropping has developed in recent years in Europe: the agroforestry market gardening system (Warlop, 2016). This particular form of professional agroforestry, where vegetables are grown in intercropping with fruit trees or berries, is found mainly in organic agriculture, on small areas (Fig. 1). Farmers combine a wide variety of crops and rely mainly on short food supply chains (Léger et al., 2018). Due to their highly agro-ecological nature, these systems seem able of addressing many of the specific challenges of developed European regions. However, the great diversity of crops in terms of phenology (tubers, leaf, root or fruit vegetables, pome, stone or nuts fruits, berries, etc.), the number of combinations, the various biological interactions to take into account and the nature of these interactions make it very difficult to acquire references on these systems. While research is underway to understand the interactions between fruit trees and vegetables (Imbert et al., 2019), the nearly unlimited number of crop combinations makes this work very tedious. In parallel, there is a substantial “grey literature” on this subject. This literature includes popular books, gardening books, websites and specialized magazines. It mainly compiles empirical knowledge resulting from the capitalization of site-specific experiments. The objective of the present work is therefore to combine scientific and grey literature in order to provide a decision support tool for farmers or new agroforestry practitioners.
