The overall objective of Crop-MATCHING is to set up a holistic approach to identify information, underutilized knowledge and best sustainable practices from small-scale farms, mix and match them into crop combinations (such as crop rotation, strip cropping, or vertical cropping) and generate new impartial and tailored knowledge specific to small farmers'/foresters' requirements. Crop-MATCHING by proposing successful and easy-to-use small-scale farming practices, aims to provide an ‘automotive’ solution to the problems smallholder farmers/foresters face in EU agriculture and at the same time, line up with the European Green Deal, Rural Vision, Climate policy and Farm to Fork strategy. What is of great concern is the fact that the number of small farms follows a sharp decrease. In this context small farms produce most of the healthy and biodiverse food that we eat every day, they provide local jobs and sustain rural activities, and they secure the resilience of our food system. Crop-MATCHING considering the important role of smallholder farmers/foresters and their need to have sustainably fair economic returns to continue farming activities and remain in the rural areas proposes the wide use of successful and easy-to-use farming practices. Through, the exploitation of various networks it is aimed to identify, diffuse, and convince farmers/foresters to adopt these successful practices. Through the proposed procedure, initially, the underutilised knowledge that appears in the literature (or identified in previous EU projects) will be mapped (more than 100 practices); almost all European territory and several pedoclimatic zones will be covered, as small and subsistence farms don't present the same structure and need everywhere. Conceptualized actions to communicate ready-to-use practices, through Crop-MATCHING, including digital cloud solutions, info packages, fact sheets, practice groups, open-access databases, e-learning, infographics, videos, website and social media.
