A sustainable food system is a fundamental requirement for the ongoing functioning and growth of society. However, despite the critical importance of the food system from both economic and social perspectives, there are several political, environmental, and human capital issues which represent barriers to sustainable production. For example, in the United States, the need for more production capacity to feed a growing population is juxtaposed with a shrinking and aging food system workforce. The nexus of such fundamentally opposed issues represents a situation in which technical solutions may be insufficient. Using a three-round Delphi process with an expert panel, a total of 106 unique leadership competencies or behaviors were identified. The resulting behaviors and competencies were then thematically analyzed using the constant comparative method. The proposed food systems leadership model, named Issue Leadership, includes 39 subthemes and 7 primary themes. The primary themes include action; change; communication; critical thinking, strategic planning and visioning; interpersonal traits and characteristics; leadership skills; and leadership processes. This study establishes the unique context that agriculture and food systems represent and the necessity for leadership models that are competency- and practice-based.
