Diversified farming systems appear to be one means of meeting the sustainability challenges facing livestock farming systems and of facilitating the renewal of future generations of farmers in a context of climatic, economic and social change. However, although work seems to be an essential issue for livestock farms, few studies have explored the impact of on-farm diversity on work. This study aims to fill the gap in our understanding of the various ways in which on-farm diversity affects work. We applied a framework combining six dimensions of work with three forms of on-farm diversity (diversity of management entities, diversity of farming activities, diversity of workers) to six studies that had been conducted previously on livestock farms. Our results highlight a wide range of links between on-farm diversity and work. We show that on-farm diversity affects various dimensions of work in multiple ways, which can be both positive and negative. For example, while there may not be a strict and clear relation between on-farm diversity and workloads, diversity provides flexibility for organizing the distribution of working time. Moreover, on-farm diversity seems to more frequently reinforce the meaning of work for farmers. Our results also show that there are multiple interactions between the six dimensions of work studied. Our study points to the need for a comprehensive approach to understanding the multifaceted and interconnected nature of work dimensions in diversified farming systems. Further research is recommended to explore these relationships more deeply to support sustainable and attractive diversified farming systems.
