As the global imperative for sustainable energy builds and with hydroelectricity proposed as one aspect of a sustainable energy profile, public discourse reflects the complex and competing discourses and social-ecological trade-offs surrounding hydropower and dams. Is hydropower “green”? Is it “sustainable”? Is it “renewable”? Does hydropower provide a necessary alternative to fossil fuel dependence? Can the ecological consequences of hydropower be mitigated? Is this the end of the hydropower era, or is it simply the beginning of a new chapter? These pressing questions circulate through discussions about hydropower in a time of changing climate, globally declining fisheries, and aging infrastructure, lending a sense of urgency to the many decisions to be made about the future of dams. The United States and European Union (EU) saw an enduring trend of dam building from the Industrial Revolution through the mid-1970s. In these countries, contemporary media discussions about hydropower are largely focused on removing existing hydropower dams and retrofitting existing dams that offer hydropower potential. Outside of these contexts, increasing numbers of countries are debating the merits of building new large-scale hydropower dams that, in many developing countries, may have disproportionate impacts on indigenous communities that hold little political or economic power. As a result, news and social media attention to hydropower outside the United States/EU often focus on activist efforts to oppose hydropower and on its complex consequences for ecosystems and communities alike. Despite hydropower’s wide range of ecological, economic, and social trade-offs, and the increasing urgency of global conversations about hydropower, relatively little work in communication studies explores news media, social media, or public debate in the context of hydropower and dam removal. In an effort to expand the scope of communication studies, after reviewing existing work the attention here shifts to research focused more broadly on human dimensions of hydropower. These dual bodies of work focus on small and large dams from Europe to the Americas to Asia and have applied a range of methods for analyzing media coverage of the hydropower debate. Those studies are reviewed here, with an emphasis on the key themes that emerge across studies—including trust, communication, local engagement, and a call to action for interdisciplinary approaches, intertwined with conflict, conflict resolution, and social and ecological resistance. The conclusion offers an original case brief that elucidates emerging themes from our ongoing research about hydropower and dam removal in the United States, and suggests future directions for research.

Methods for Assessing Visual Images and Depictions of Climate Change
Visual representation has been important in communicating and constructing the environment as a focus for public and political concern since the rise of environmentalism in the 1960s. As communications media have themselves become increasingly visual with the rise of digital media, so too has visual communication become key to public debate about environmental issues, no more so than in public debate and the politics of climate change. This chapter surveys the methods, approaches, and frameworks deployed in emerging research on public-mediated visual communication about climate change. Research on the visual mediation of climate change is itself part of the emerging field of visual environmental communication research, defined as research concerned with theorizing and empirically examining how visual imagery contributes to the increasingly multimodal public communication of the environment. Focused on a sociological understanding of the contribution that visuals make to the social, political, and cultural construction of “the environment,” visual environmental communication research analytically requires a multimodal approach, which situates analysis of the semiotic, discursive, rhetorical, and narrative characteristics of visuals in relation to the communicative, cultural, and historical contexts and in relation to the three main sites—production, content, and audiences/consumption—of communication in the public sphere.
