Which variables influence the succession process in family farms? A literature review[Quelles variables influencent le processus de succession dans les exploitations agricoles familiales ? Revue de littérature]

The decrease in family farm succession is a problem in many countries worldwide. However, no systematic compilation of relevant studies exists. The method of analysis described in this article enabled us to obtain descriptive statistical results such as: most-studied variables, least-studied variables, patterns in the effects of the variables on succession, new types of variables analyzed, and principal approaches of the qualitative studies. We conducted a literature search in four databases, which resulted in 59 papers relevant to the topic. Twenty-nine of them are quantitative and 30 are qualitative. The literature search in peer-reviewed journals in English resulted primarily in articles from developed countries. Due to this, the selection, analysis and results turned out to be focused on Global North countries. Likewise, the studies considered are focused mainly on the opinion of the principal farmer and disregard that of other family members. From the quantitative studies, we analyzed five groups of variables (farmer, farm, family, context and psychological variables). The farmer variables are the most studied and the context and psychological variables are the least studied. We identified four axes around which the qualitative studies focused: socioeconomic factors, communication between father and heir about the process of succession, integration in decision-making and trust in the heir, and training the successor. Adding new countries (e.g. from Sub-Saharan Africa) and generating new models including psychological, context, and qualitative variables could lead to new ways of understanding such a complex issue.
