Coding the Commons Wiki

Screen Shot 2018-01-13 at 5.18.42 PMThe Coding the Commons Wiki exists to help researchers learn from others and compare approaches to their research on the commons. It can be used and improved by researchers, students, and practitioners engaged in the analysis of social-ecological systems or other coupled infrastructure systems to improve our collective understanding.

It builds directly off the work of Elinor Ostrom, Edella Schlager, and Shui Yan Tang — who, in 1987, created the original Common Pool Resource (CPR) coding database which has become a part of the Social-Ecological Systems (SES) Library.

Researchers on the commons have coded data from games, experiments, surveys and literature according to various frameworks and theories. This wiki is intended to be a collaborative repository to share codebooks, variables, to improve interdisciplinary vocabulary, and to enable comparative research.
