In recent decades, Italy has been affected by a generalized decrease in rainfall, which has led to water emergency situations, causing severe limitations especially in the agricultural sector. To mitigate the effects, strategies aimed at rationalizing the uses of the water resource were used. In this context, the “minor and widespread water resources” are of strategic importance, generally unused due to their low cost in mono-functional terms, especially in protected areas, where there are restrictions on use imposed by legislation. Certainly more profitable is the multi-functional use of these resources, which can be obtained through the re-functionalization of supply sources, re-functionalization of local irrigation water schemes and the re-introduction of storage, drainage and canalization practices. Multi-functional use actually refers to different opportunities to be exploited. First of all, the possibility of enhancing the context of sustainable and blue agriculture for the production of local varieties with high added value, typical of the Mediterranean diet model and of promoting, safeguarding and managing the local ecological network and biodiversity. Secondly, the re ‐ functionalization of drainage works increases the ability of the natural network to intercept and remove surface runoff waters, providing the opportunity for a measure to contrast soil erosion and hydrogeological risk. This is associated with the opportunity to protect, restore and enhance a set of elements typical of the agricultural and rural landscape of the realities involved. The sectoral reference scenario is represented by the wine and oil agri-food chain. The collective project involves companies and OPs (stakeholders) located outside the main territorial area of reference, with an interest in exporting the proposed methodologies also in different regional territorial contexts.
