Basilicata is a small Italian region with a high percentage of marginal agricultural land, characterized by difficult environmental conditions that pose a challenge for agriculture and livestock farming, but which can become a productive, valuable and profitable resource for local communities and the environment. In a sustainable management approach, considering the potential and limitations of the area, the most appropriate choice is to focus on hardy breeds, which are more resistant and can effectively use fodder resources even if not of excellent quality. Dairy products related to these herds in marginal lands have better nutritional qualities, higher market value and contribute to the achievement of environmental, cultural, recreational, tourism and social benefits. This paper shows some considerations on both dairy farming and processing activities in Basilicata (Southern Italy), and points out their importance in terms of the development of agritourism activities and land promotion, an aspect that has been little investigated so far in this territorial context. The paper focuses on some experiences and case studies carried out in recent years, and on the prospects for further development in terms of safeguarding marginal areas and maintaining agritourism economic activity, as well as land conservation and protection.
