Co-production of knowledge (through project design or research) is viewed as an effective approach to solving environmental problems, which may also increase community adaptive capacity in the face of climate change. However, the reality is that little is known about long-term impacts of co-production on researchers, communities, and outputs. We qualitatively analyzed case studies to understand co-production processes and related adaptive capacity outcomes. These 13 case studies were developed to identify impacts of the United States Department of Agriculture National Institute of Food and Agriculture water (2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013) and climate (2010-2015) portfolios, which funded projects focused on research, education, and extension related to climate and water issues on working lands. Case study data included interviews, survey responses, and analysis of reports and publications related to a single project. We found that projects which were responsive to specific needs and assets of stakeholders had strong connections to adaptive capacity outcomes, but that these projects did not necessarily entail highly interactive practices of co-production of knowledge (e.g., stakeholder-driven research with continuous interactions between academic and non-academic partners). Our research provides evidence to suggest that, in some contexts, engagement approaches that are less time-and resource-intensive for stakeholders may be as effective at building adaptive capacity as highly interactive co-production efforts.
