| Outline of Final Research Achievements |
River watersheds have not only provided essential natural resources for the sustenance of human and nonhuman lives but also caused devastating damage through floods. Yet, historical and contemporary claims over river resources led to the formation of particular river governance that facilitated the state’s territorial control and overexploitation of river resources. Our research explored the possibility of conceptualizing river watersheds as a commons, and examined how policy discussions can integrate into river watershed governance the multiplicity human and nonhuman actors, their overlapping interests, and their divergent temporal and spatial senses.

| Academic Significance and Societal Importance of the Research Achievements |
Our research shows that shifting social-ecological relations over the last 150 years have shaped and been shaped by the state’s efforts to territorialize river watersheds, categorize them, and commodify their resources.
