Many population centers in the American West rely on water from the Colorado River Basin, which has faced shortages in recent years that are anticipated to be exacerbated by climate change. Shortages to urban water supplies related to climate change will not be limited to cities dependent on the Colorado River. Considering this, addressing sustainable water governance is timely and critical for cities, states, and regions facing supply shortages and pollution problems. Engaging in sustainability transitions of these hydro-social systems will increase the ability of such systems to meet the water needs of urban communities. In this paper, we identify historical transitions in water governance and examine their context for three sites in the Colorado River Basin (Denver, Colorado, Las Vegas, Nevada, and Phoenix, Arizona) to provide insight for intentional transitions towards sustainable, or “water sensitive” cities. The comparative historical approach employed allows us to more fully understand differences in present-day water governance decisions between the sites, identify past catalysts for transitions, and recognize emerging patterns and opportunities that may impact current and future water governance in the Colorado River Basin and beyond.

Differences in governance relationships and community efforts to remove an exotic, rapidly spreading invasive plant, the-mile-a-minute weed (Mikania micrantha), are explored in five case study community forests in the subtropical region of Chitwan, Nepal. An institutional analysis informs an examination of the de jure (formal) versus de facto (on the ground) institutions and actor relationships relevant to Mikania removal efforts. Contrary to the expectations set by the de jure situation, we find heterogeneous governance relationships and norms related to Mikania management across community forests. Content analysis of interview data illuminates reoccurring themes and their implications for social and ecological outcomes in the communities. Complex governance relationships and regular discussion of distrust of government and non-government officials help explain collective action efforts and management decisions. The content analysis suggests that Mikania is impacting people’s daily lives but the degree of severity and the response to the disruption varies substantially and is heavily affected by other problems experienced by community forest members. Our results indicate that understanding how the de facto, or on the ground situation, differs from the de jure institutions may be vital in structuring successful efforts to manage invasive species and understanding collective action problems related to other social-ecological threats. We present data-informed propositions about common pool resource management and invasive species. This study contributes to a better scientific understanding of how institutions mediate social-ecological challenges influencing common pool resources more broadly.

Engaged research emphasizes researcher–stakeholder collaborations as means of improving the relevance of research outcomes and the chances for science-based decision-making. Sustainability science, as a form of engaged research, depends on the collaborative abilities and cooperative tendencies of researchers. We use an economic experiment to measure cooperation between university faculty, local citizens, and faculty engaged in a large sustainability science project to test a set of hypotheses: (1) faculty on the sustainability project will cooperate more with local residents than non-affiliated faculty, (2) sustainability faculty will have the highest level of internal cooperation of any group, and (3) that cooperation may vary due to academic training and culture in different departments amongst sustainability faculty. Our results demonstrate that affiliation with the sustainability project is not associated with differences in cooperation with local citizens or with in-group peers, but that disciplinary differences amongst sustainability faculty do correlate with cooperative tendencies within our sample. We also find that non-affiliated faculty cooperated less with each other than with faculty affiliated with the sustainability project. We conclude that economic experiments can be useful in discovering patterns of prosociality within institutional settings, and list challenges for further applications.
