This report briefly examines government intervention as an option for developing mango supply chains from disorganised and segmented to organised and integrated. The report includes a brief theoretical review of supply chain management and complex adaptive systems. Methodology included interviews with stakeholders over three time periods. The paper then reports on two case studies of government intervention in West Java and East Java including a description of the supply chains, the interventions and the responses to the intervention along the supply chain. In these cases, the government intervention focused on exclusion of the middlemen. The authors provide insights into the failure of these interventions. An alternative model to achieve self-organising supply chain formation is discussed based on theory and the learnings from the case studies. The authors highlight the need to recognise the self-organising characteristics of supply chains and consider these when designing interventions.
