This paper aims to analyze the role of newcomer farmers on farming system innovations. It is based on a two-months long field work in Southern Portugal’s Alentejo region. The analysis of 27 interviews with farmers and members of agricultural organizations reveals neo-farmers’ contribution to farming system innovations at three scales: the farm scale, the scale of professional networks, and the territorial scale.
According to the literature on regime transition, niches are sources of innovation that may lead to the transformation of the dominant regime, if processes at other level of the system – the landscape and the mainstream regime - are supportive. A focus on actors involved in the transition process and the analysis of their specific role in knowledge networks can help assessing the robustness of a specific niche and its growth potential. Knowledge systems, and in particular the dynamics of local and expert knowledge, have in fact a key role in innovation models.
