To transform the food system towards agroecology, diversified farming systems are to be developed. Such systems require crop diversification which can rely on multiple options (e.g. intercropping), one of which being the introduction of minor crops in cropping systems. This is a grand challenge given the current European land use dominated by a small number of crops. Farmers lack locally-relevant agronomic knowledge to cultivate minor crops and overall, they lack outlets for minor crop food products due to low consumption habits. Given the significant impact of institutional catering on production and consumption practices, it can serve as a powerful lever to promote the development of minor crops. Such a development requires jointly addressing cultivation, storage, pre-processing, cooking and consumption issues.

The CropCat project thus aims at developing the cultivation of minor crops in farmers’ fields and the consumption of related products in canteen guest plates following a co-innovation and interdisciplinary approach. To do so, we will (i) establish guidelines to run living labs, where innovations on minor crops will be developed across stages of the value chain, and assess the outcomes induced, including co-learning; (ii) characterize the agroecological performance of minor crops and improve cultivation techniques to close yield gaps, and promote the delivery of other ecosystem services; (iii) develop low-tech pre-processing technologies to prevent metabolic changes during storage and preserve the sanitary and nutritional quality of products derived from minor crops thus limiting spoilage; (iv) define a framework to capture the value of minor crop food products into new business models based on institutional catering; (v) develop a set of nudges to consumers’ choices of dishes based on minor crop food products to ensure their acceptance; (vi) identify policy instruments and governance frameworks supporting the development of minor crops from farmers’ fields to canteen plates through procurement arrangements.
