As managers of agricultural and natural resources are confronted with uncertainties in global change impacts, the complexities associated with the interconnected cycling of nitrogen, carbon, and water present daunting management challenges. Existing models provide detailed information on specific sub-systems (e.g., land, air, water, and economics). An increasing awareness of the unintended consequences of management decisions resulting from interconnectedness of these sub-systems, however, necessitates coupled regional earth system models (EaSMs). Decision makers' needs and priorities can be integrated into the model design and development processes to enhance decision-making relevance and "usability" of EaSMs. BioEarth is a research initiative currently under development with a focus on the U.S. Pacific Northwest region that explores the coupling of multiple stand-alone EaSMs to generate usable information for resource decision-making. Direct engagement between model developers and non-academic stakeholders involved in resource and environmental management decisions throughout the model development process is a critical component of this effort. BioEarth utilizes a bottom-up approach for its land surface model that preserves fine spatialscale sensitivities and lateral hydrologic connectivity, which makes it unique among many regional EaSMs. This paper describes the BioEarth initiative and highlights opportunities and challenges associated with coupling multiple stand-alone models to generate usable information for agricultural and natural resource decision-making.
Integrating stakeholder perspectives is increasingly important in environmental science as a growing number of research projects are justified with a "solutions" orientation prioritizing societal relevance. In earth systems modeling, there is potential for model developers to engage with stakeholders who may use modeling results to inform decisions about resource management and policy. Challenges associated with stakeholder engagement relate to how researchers perceive the role of stakeholders and how they view the utility of integrating knowledge and perspectives from outside academia in model development. This study analyzes researchers' perceptions of stakeholder engagement within BioEarth, a large collaborative regional earth systems modeling project designed to integrate input from agriculture and forestry sector decision-makers. The project addresses the impact of climate change on water, nitrogen and carbon cycling in the US Pacific Northwest. Surveys and semi-structured interviews were conducted to assess perceptions of stakeholder engagement among the 18principal investigators (PIs). Results reveal that PIs have varying perceptions of the role of stakeholders in earth systems modeling and diverse assessments of the optimal type and timing of stakeholder engagement. As funding agencies and research institutions promote increased collaboration with stakeholders from outside academia, these findings demonstrate fundamental differences of opinion among environmental scientists regarding the value of stakeholder engagement. This research has implications for transdisciplinary research projects that seek to address sustainability challenges by involving stakeholders in technical academic modeling. Facilitating learning opportunities for researchers who are new to stakeholder engagement is essential, as is close collaboration among researchers with different levels of prior stakeholder engagement experiences.
In order for agricultural systems to successfully mitigate and adapt to climate change there is a need to coordinate and prioritize next steps for research and extension. This includes focusing on "win-win" management practices that simultaneously provide short-term benefits to farmers and improve the sustainability and resiliency of agricultural systems with respect to climate change. In the Northwest U.S., a collaborative process has been used to engage individuals spanning the research-practice continuum. This collaborative approach was utilized at a 2016 workshop titled "Agriculture in a Changing Climate," that included a broad range of participants including university faculty and students, crop and livestock producers, and individuals representing state, tribal and federal government agencies, industry, nonprofit organizations, and conservation districts. The Northwest U.S. encompasses a range of agro-ecological systems and diverse geographic and climatic contexts. Regional research and science communication efforts for climate change and agriculture have a strong history of engaging diverse stakeholders. These features of the Northwest U.S. provide a foundation for the collaborative research and extension prioritization presented here. We focus on identifying research and extension actions that can be taken over the next 5 years in four areas identified as important areas by conference organizers and participants: (1) cropping systems, (2) livestock systems, (3) decision support systems to support consideration of climate change in agricultural management decisions; and (4) partnerships among researchers and stakeholders. We couple insights from the workshop and a review of current literature to articulate current scientific understanding, and priorities recommended by workshop participants that target existing knowledge Yorgey et al.Priorities for U.S. Northwest Agriculture in a Changing Climate gaps, challenges, and opportunities. Priorities defined at the Agriculture in a Changing Climate workshop highlight the need for ongoing investment in interdisciplinary research integrating social, economic, and biophysical sciences, strategic collaborations, and knowledge sharing to develop actionable science that can support informed decision-making in the agriculture sector as the climate changes.
