Complex agriculture projects directly affect the welfare of over half the world’s population, are a key Sustainable Development Goal (SDG), and account for the single most extensive human activity across 40% of the world’s surface. Furthermore, they are highly susceptible to environmental, social, and economic pressures such as climate change, cyclical pandemics, market disruptions, and diminishing arable land. These issues are also becoming increasingly vital in dint of the fact that population growth is placing increasing pressure on sustainable priorities. However, a recent scientometric review indicates a significant paucity in the extant literature on agriculture projects, with a pressing need for further research to examine sustainable project management practices from an institutional perspective. This research, therefore, aims to respond to this gap in the literature by drawing on Institutional Theory through a multi-case study of Agriculture Co-operative Institutions (ACIs). These are often viewed as valuable vehicles to deliver agricultural projects which can benefit communities, especially in emerging markets. Initial findings from two rounds of fieldwork as well as an extensive literature review suggest that ACIs as value-based organisations embedded within institutional contexts help stimulate elements of agility in project management processes, to deliver sustainable outcomes for their members and external stakeholders. Agile ACI project managers can also stimulate innovative outcomes across broader sustainable agriculture projects. It is the aim of this research also to undertake a larger cross-country comparison with international research cases. Therefore, this study will aim to not only contribute to critical project management discourse and knowledge but also to uncover agile project management practices for future pressing policy development and implementation to help foster greater sustainable agriculture project processes.
