This study uses semi-structured interviews and an online survey to explore the structure, challenges
and outcomes of a five-year National Science Foundation-funded water scarcity modelling project in the
Willamette River Basin of Oregon, USA. The research team chose to facilitate broader impacts by engaging
stakeholders from the study’s inception (e.g. developing grant proposal, study implementations, defining model
run scenarios) through its completion and extension of findings. The team used various engagement formats (field
trips, small and large group meetings) and encountered many challenges, including the lack of a shared vision,
different professional languages, research complexities and project management. Through stakeholder
engagement the team overcame challenges, facilitated learning, and improved and extended the research process
and results. Participation in engagement events was positively correlated with beneficial broader impact
outcomes. We compare these outcomes with NSF’s five broader impact criteria: advance scientific discovery and
understanding, broaden participation of underrepresented groups, enhance research infrastructure, broadly
disseminate results, and benefit society. We show that stakeholder engagement is one method to achieve the five
original NSF criteria and suggest that a sixth criterion can be achieved through stakeholder engagement – that of
developing the research community
