Addressing The Complexities Of Boundary Work In Sustainability Science Through Communication, Bridie Mcgreavy, Karen Hutchins, Hollie Smith, Laura Lindenfeld, Linda Silka

New Hampshire EPSCoR

Sustainability science seeks to identify and implement workable solutions to complex problems. This transdisciplinary approach advances a commitment to work across boundaries that occur among individuals, disciplines, and institutions to build capacities for informed and innovative decision making in the face of uncertainty and change. The concept of boundary work and related discussions of boundary objects and organizations are important, expanding focal areas within sustainability science. While communication is described as central to boundary work, insights from the field of communication have largely yet to inform theorizing about boundaries within sustainability science. In this paper, we highlight three communication perspectives, …

To examine whether stream nitrogen concentrations in forested reference catchments have changed over time and if patterns were consistent across the USA, we synthesized up to 44 yr of data collected from 22 catchments at seven USDA Forest Service Experimental Forests. Trends in stream nitrogen presented high spatial variability both among catchments at a site and among sites across the USA. We found both increasing and decreasing trends in monthly flow-weighted stream nitrate and ammonium concentrations. At a subset of the catchments, we found that the length and period of analysis influenced whether trends were positive, negative or non-significant. Trends …
