Seram is Indonesia's 8th largest island. It is central to the historic spice islands, once a hotbed for international trade of profitable treeâproducts, primarily clove and nutmeg. Recent increased rates of social and ecological change, including costly conflicts, present Seram with new challenges and opportunities for conservation and development. Using placeâbased transdisciplinary research methods, we diagnose the problems emerging in Seram. Engaging with actors across multiple scales and sectors, we explore drivers of change, socialâecological impacts, and institutional arrangements that might achieve improved inclusive and sustainable development outcomes. Traditional and formal governance arrangements require harmonizing to optimize the benefits and costs from largeâscale investments arriving in Seram. Organizations wishing to achieve positive impact can more strategically engage with the broad range of actors to harmonize divergent visions for the future and confront the reality of incoming investments and infrastructure.
