National Inventory

Aging water infrastructure in the United States (U.S.) is a growing concern. In the U.S., over 90,000 dams were registered in the 2018 National Inventory of Dams (NID) database, and their average age was 57 years old. Here, we aim to assess spatiotemporal patterns of the growth of artificial water storage of the existing dams and their hazard potential and potential economic benefit. In this study, we use more than 70,000 NID-registered dams to assess the cumulative hazard potential of dam failure in terms of the total number and the cumulative maximum storage of dams over the 12 National Weather Service River Forecast Center (RFC) regions. In addition, we also estimate potential economic benefits of the existing dams based on their cumulative storage capacity. Results show that the ratios of the cumulative storage capacity to the long-term averaged precipitation range from 8% (Mid-Atlantic) to 50% (Colorado), indicating the significant anthropogenic contribution to the land surface water budget. We also find that the cumulative storage capacity of the dams with high (probable loss of human life is if the dam fails) and significant (potential economic loss and environmental damage with no probable casualty) hazard potential ranges from 50% (North Central) to 98% (Missouri and Colorado) of the total storage capacity within the corresponding region. Surprisingly, 43% of the dams with either high or significant potential hazards have no Emergency Action Plan. Potential economic benefits from the existing dams range from $0.7 billion (Mid Atlantic) to $15.4 billion (West Gulf). Spatiotemporal patterns of hazard potential and economic benefits from the NID-registered dams indicate a need for the development of region-specific preparation, emergency, and recovery plans for dam failure. This study provides an insight about how big data, such as the NID database, can provide actionable information for community resilience toward a safer and more sustainable environment.

The Way

The COVID-19 pandemic has changed the way of life of the world’s population, and initially all non-essential commercial and industrial activities in all countries were suspended, as well as the temporary closure of major airports and educational activities. As never before, environmental sound levels were reduced as a result of the quarantine, as the authorities ordered people to remain confined in their homes in order to reduce and prevent the SARS-CoV-2 transmission. Cities became silent and in some cases birds and wildlife “took over” this situation. This change in the soundscape led to sounds that were previously masked, now being heard, i.e. HVAC and other noises. This article presents the case of Lima, Peru, in which the impact and annoyance produced by aircrafts overflights are analyzed (during 2020); as well as the healthy soundscape levels achieved ‘thanks’ to the commercial lockdown and leisure activities.

The rapid spread of COVID-19 has damaged the economy in the United States. To understand the resilience capacities of local businesses, we visualized the spatiotemporal patterns of permanently closed Points of Interest (POIs) after the outbreak of the pandemic. The results show that the counties with more business closures are also the counties with a larger population. The permanent closures of most local businesses occurred immediately after the lift of stay-at-home order. We also found that those business owners, who permanently shut down their businesses, may not open new ones elsewhere. In addition, the permanent closures of entertainment and recreation businesses are significantly less than that of retail and trade businesses and food services.

This essay employs Anthropocene frameworks to examine United States independent director Kelly Reichardt’s quiet vignettes of American precarity through the interpretive cinematic apparatus. Reichardt’s slow style and lingering gaze are primarily read as affective interpretations of human exhaustion or as a critique of capital temporalities. However, the critical attention paid toward the human in Reichardt’s films overlooks the primacy of landscape as a site of knowledge in the visual aesthetic. It is the entanglement between the human and the landscape in Reichardt’s films that invites an Anthropocene reading based on core concepts of time, scale, and the disruption of the modernist nature/culture binary. In Old Joy (2006) and Wendy and Lucy (2008), local, global, and planetary scales are made explicit and conflict with human structures such as gender and neoliberal economies. Reichardt’s work explores the manufactured landscape of Oregon and the Florida Everglades (respectively) in Night Moves (2013) and River of Grass (1994), pointing toward larger structural issues at play in traditional conservationism and narratives of progress. Finally, in her Western-influenced films Meek’s Cutoff (2010) and Certain Women (2016), Reichardt’s use of environmental sound provides the critique of American expansionist ideology’s depiction of and attempt to consume Indigeneity. Taken together, Reichardt’s filmography presents a compelling case for cinema’s role as mediator of the Anthropocene crisis.
