The Costs Of Obtaining Environmental Outcomes Through Coastal Habitat Restoration, Shea Gould, Matthew G. Interis

Journal of Ocean and Coastal Economics

Studies examining the costs of coastal habitat restoration have focused on the cost per acre of restoration or on cost efficiency of various restoration methods. On the other hand, studies examining the benefits of restoration have focused on various ecosystem services that more directly affect welfare including amenity value, storm protection, nutrient retention and biodiversity. We examine a set of 133 Gulf of Mexico coastal habitat restoration projects to estimate the cost of obtaining average annual habitat units (AAHUs), a measure which captures the quantity and, importantly, quality of habitat restored, which is one of the more direct ecosystem service …

A Global Database Of Surface Urban Heat Island Intensity, Tc Chakraborty, Xuhui Lee

Yale Day of Data

The urban heat island (UHI) effect - the phenomenon of higher temperatures in urban environments - is one of the most well-known consequences of urbanization on local climate. We develop the simplified urban-extent (SUE) algorithm, a new algorithm to estimate the urban heat island (UHI) intensity at a global scale. This algorithm is implemented on the Google Earth Engine platform and uses satellite-derived images to calculate the surface UHI intensity for over 9500 urban clusters covering 15 years, making this the most comprehensive global UHI database. The data are validated against previous multi-city studies and then used to estimate the …

Topovar90m: Global High-Resolution Topographic Variables For Environmental Modeling, Giuseppe Amatulli Dr.

Yale Day of Data

Topographical relief involves the vertical and horizontal variation of the Earth's terrain and it drives processes in hydrology, climatology, geography and ecology. Its assessment and characterization is fundamental for various types of modeling and simulation analysis. In this regard, the Multi-Error-Removed Improved Terrain (MERIT) Digital Elevation Model (DEM) currently provides the best high-resolution DEM globally available, at a 3 arc-second resolution (90m), due to the removal of multiple error components from the underlying SRTM3 and AW3D30 DEMs. To depict topographical variations worldwide, we developed a new dataset comprising different terrain features derived from the MERIT-DEM. The fully standardized topographical variables …

Climate Change, Agriculture, And Adaptations: Policy Recommendations For Conservation Agriculture, Sydney Abraham, Mel Dollison

Climate and Society

This paper examines the intersection of climate change and agriculture with a focus on possibilities for sustainable agriculture in a warmer world. The authors consider the impacts (both positive and detrimental) of climate change on food production systems before engaging with a variety of adaptive strategies including crop diversification, genetically modified organisms (GMOs), and conservation agriculture (CA). These strategies are then applied within the context of sub-Saharan agricultural policy. Ultimately, the authors suggest that policymakers should support rural agriculture by prioritizing conservation agriculture as a critical piece of both mitigation and adaptation policy.

Maintaining Stability In A Changing Climate: A Comparative Analysis Of Public Health Systems And Migration Policies In The U.S. And Canada, Laura Cutlip

Climate and Society

This paper examines the relation between climate change, migration, and public health to better understand how the United States health system is positioned to deal with likely challenges to human health posed by environmental changes. The author reviews probable impacts of climate change on population displacement and disease before considering how the current structure of the health system of the United States will render it unable to adapt to these changes and challenges. The Canadian health care system and refugee policies are then reviewed to provide a counterpoint to this analysis. These findings are then considered in tandem as the …

Local Entities As Mechanisms For Global Climate Governance, Daniel Vernick, Cameron Stanish, Joshua Hill

Climate and Society

This paper considers the role of local government entities as actors in global climate governance regimes. The authors review traditional state-based climate governance efforts and existing attempts to engage municipal and local actors through transnational municipal networks (TMNs). Arguing for the importance of TMNs to effective and time-sensitive climate action, the authors then show how and why TMNs are crucial to future efforts to address climate mitigation as part of multi-level, holistic plans for global climate governance.

After The Fall: Legacy Effects Of Biogenic Structure On Wind-Generated Ecosystem Processes Following Mussel Bed Collapse, John A. Commito, Brittany R. Jones, Mitchell A. Jones, Sondra E. Winders, Serena Como

Environmental Studies Faculty Publications

Blue mussels (Mytilus edulis) are ecosystem engineers with strong effects on species diversity and abundances. Mussel beds appear to be declining in the Gulf of Maine, apparently due to climate change and predation by the invasive green crab, Carcinus maenas. As mussels die, they create a legacy of large expanses of shell biogenic structure. In Maine, USA, we used bottom traps to examine effects of four bottom cover types (i.e., live mussels, whole shells, fragmented shells, bare sediment) and wind condition (i.e., days with high, intermediate, and low values) on flow-related ecosystem processes. Significant differences in transport of sediment, meiofauna, …

Pinngortitaq – A Place Of Becoming, Ann E. Lennert, Jørgen Berge

Journal of Ecological Anthropology

Arctic ecosystems are on the verge of changes that are unprecedented in both magnitude and velocity. We stress that statements of a changing climate and environment have ambiguous definitions in both theoretical and metaphorical senses. Inuit have embraced the idea of an environment in a process of Pinngortitaq – a place of becoming – rather than a process of changing. In this note, we accentuate how a philosophy of a world becoming can inspire to answer some of the complex environmental questions asked today by enabling more flexible management regimes in the future.

Soil Moisture Monitoring Using Remote Sensing Data And A Stepwise-Cluster Prediction Model: The Case Of Upper Blue Nile Basin, Ethiopia, Getachew Ayehu, Tsegaye Tadesse, Berhan Gessesse, Yibeltal Yigrem

National Drought Mitigation Center: Faculty Publications

In this study, a residual soil moisture prediction model was developed using the stepwise cluster analysis (SCA) and model prediction approach in the Upper Blue Nile basin. The SCA has the advantage of capturing the nonlinear relationships between remote sensing variables and volumetric soil moisture. The principle of SCA is to generate a set of prediction cluster trees based on a series of cutting and merging process according to a given statistical criterion. The proposed model incorporates the combinations of dual-polarized Sentinel-1 SAR data, normalized difference vegetation index (NDVI), and digital elevation model as input parameters. In this regard, two …

Rapa Nui (Easter Island) Monument (Ahu) Locations Explained By Freshwater Sources, Robert J. Dinapoli, Carl P. Lipo, Tanya Brosnan, Terry L. Hunt, Sean W. Hixon, Alex E. Morrison, Matthew Becker

Anthropology Faculty Scholarship

Explaining the processes underlying the emergence of monument construction is a major theme in contemporary anthropological archaeology, and recent studies have employed spatially-explicit modeling to explain these patterns. Rapa Nui (Easter Island, Chile) is famous for its elaborate ritual architecture, particularly numerous monumental platforms (ahu) and statuary (moai). To date, however, we lack explicit modeling to explain spatial and temporal aspects of monument construction. Here, we use spatially-explicit point-process modeling to explore the potential relations between ahu construction locations and subsis- tence resources, namely, rock mulch agricultural gardens, marine resources, and freshwa- ter sources—the three most critical resources on Rapa …

Role Of The Atchafalaya River Basin In Regulating Export Fluxes Of Dissolved Organic Carbon, Nutrients, And Trace Elements To The Louisiana Shelf, Dongjoo Joung, Laodong Guo, Alan M. Shiller

Faculty Publications

The abundance and fluxes of selected dissolved trace elements (TE), nutrients, and dissolved organic carbon (DOC) were quantified in the Atchafalaya River Basin to better understand its influence on the chemical regime of the Louisiana Shelf, a region where bottom water hypoxia occurs annually during late spring to early fall. Water samples were collected from throughout the entire Atchafalaya River Basin including from the Mississippi and Red Rivers as well as basin swamp waters during April and November 2010, and June 2011, which represent “typical” high and low, and “unusual” high river discharges, respectively. Within the total dissolved (< 0.45 µm) pool, most of the TEs were mainly partitioned to the < 0.02 µm dissolved phase with the exception of Cr, Cs, Fe, Pb and Zn which were dominantly in the colloidal (0.02-0.45 µm) phase. In the Atchafalaya River, seasonal concentration variations in nutrients, DOC and most TEs were similar to those in the Mississippi River, reflecting a major contribution of water from the Mississippi River. Contributions of the Red River to the Atchafalaya River’s DOC and nutrients were estimated to be 1-35%, similar to previous estimates for this system. The Red River contribution to the fluxes of Co, Cr, Cs, Fe, Mn, Pb, Rb, and Zn was generally disproportionally high (>20%), …

Sustainability And Disaster Planning: What Are The Connections?, George C. Homsy, Lu Liao, Mildred E. Warner

Public Administration Faculty Scholarship

In this paper, we examine the connections between resiliency and sustainability by asking: can disaster planning lead to more sustainability actions? In a survey we conducted of 1,899 cities, towns, and counties across the United States in 2015, we found that disaster plans are three times more common than sustainability plans. Our regression models find both types of plans lead to sustainability action as does regional collaboration across the rural-urban interface. However, we find that hazard mitigation planning may be done without including sustainability staff, citizens, and other officials. After controlling for motivations, capacity, and cooperation, we find rural communities …

Grassroots Organizing And Medicaid Expansion In Virginia: The Lee County Chapter Of Virginia Organizing And Medicaid Expansion, Brian Johns, Rosemary Gould, Ladelle Mcwhorter

Richmond Public Interest Law Review

The ability to participate in grassroots organizing derives implicitly from the Constitution’s declaration of “We the People” and explicitly from the First Amendment’s guarantee of the right to petition the Government for redress. At Virginia Organizing, we take this grant of power very seriously as is evident from our recent grassroots organizing for Medicaid expansion in Virginia. Our work focused predominately on more rural parts of the Commonwealth where our chapter members have experienced the consequences of a lack of access to health care. By mobilizing individuals passionate about Medicaid expansion and those who suffer from the lack of it …

Grey Water: Agricultural Use Of Reclaimed Water In California, Bahman Sheikh, Kara L. Nelson, Brent Haddad, Anne Thebo

Journal of Contemporary Water Research and Education

Potential for use of recycled water is great, especially for agricultural irrigation, which comprises by far the highest percentage of water taken from developed sources in the arid and semi-arid regions of the world. In California, 80% of developed water is used for agriculture, and the same pattern prevails throughout the western United States. The potential for recycled water use in agriculture remains under-realized because of numerous impediments. Understanding how the incentives and impediments to agricultural reuse vary based on local context is critical to understanding the tradeoffs and technology requirements for different end uses of recycled water. Public perceptions …

Actions Speak Louder Than Words: Designing Transdisciplinary Approaches To Enact Solutions, Vanessa R. Levesque, Aram J. K. Calhoun, Kathleen P. Bell

Faculty Publications

Sustainability science uses a transdisciplinary research process in which academic and non-academic partners collaborate to identify a common problem and co-produce knowledge to develop more sustainable solutions. Sustainability scientists have advanced the theory and practice of facilitating collaborative efforts such that the knowledge created is usable. There has been less emphasis, however, on the last step of the transdisciplinary process: enacting solutions. We analyzed a case study of a transdisciplinary research effort in which co-produced policy simulation information shaped the creation of a new policy mechanism. More specifically, by studying the development of a mechanism for conserving vernal pool ecosystems, …

Hrísheimar: Fish Consumption Patterns, Wendi K. Coleman

Theses and Dissertations

In this thesis, I examine the fish remain patterns at Hrísheimar, which have provided archaeologists with further evidence that inland sites such as those in the Mývatnssveit Region utilized both local freshwater and marine fish from the coastal regions as a part of their subsistence pattern.

Weak Effects Of Geolocators On Small Birds: A Meta-Analysis Controlled For Phylogeny And Publication Bias, Vojtěch Brlík, Noah G. Perlut

Environmental Studies Faculty Publications

Currently, the deployment of tracking devices is one of the most frequently used approaches to study movement ecology of birds. Recent miniaturization of light-level geolocators enabled studying small bird species whose migratory patterns were widely unknown. However, geolocators may reduce vital rates in tagged birds and may bias obtained movement data. There is a need for a thorough assessment of the potential tag effects on small birds, as previous meta-analyses did not evaluate unpublished data and impact of multiple life-history traits, focused mainly on large species and the number of published studies tagging small birds has increased substantially. We quantitatively …

Vintage Report 2018: North Willamette Valley, Gregory V. Jones

Linfield University Wine Studies Reports

This report describes the impacts of climate and phenology on vintage for the North Willamette Valley in Oregon in 2018. A relatively mild and dry winter set the stage for a 2018 growing season that was highlighted by a cool spring, a summer with low heat stress but high drought stress along with numerous regional fires, and a glorious October. The moderately cool spring led to a late start to the growing season with an average bud break of April 17th delayed by 5-10 days compared to average. However, a warm May through August brought plant growth timing to near …

Sex‐Biased Survival Contributes To Population Decline In A Long‐Lived Seabird, The Magellanic Penguin, Natasha J. Gownaris, P. D. Boersma

Environmental Studies Faculty Publications

We developed a Hidden Markov mark–recapture model (R package marked) to examine sex‐specific demography in Magellanic Penguins (Spheniscus magellanicus ). Our model was based on 33 yr of resightings at Punta Tombo, Argentina, where we banded ~44,000 chicks from 1983 to 2010. Because we sexed only 57% of individuals over their lifetime, we treated sex as an uncertain state in our model. Our goals were to provide insight into the population dynamics of this declining colony, to inform conservation of this species, and to highlight the importance of considering sex‐specific vital rates in demographic seabird studies. Like many other …

The Un Local Communities And Indigenous Peoples' Platform: A Traditional Ecological Knowledge-Based Evaluation, Zoha Shawoo, Thomas F. Thornton

Faculty, Staff, and Students

This review evaluates the potential of the proposed local communities and Indigenous peoples’ platform to effectively engage traditional ecological knowledge (TEK) for climate policy. Specifically, we assess the platform's potential to enable greater representation and participation of Indigenous peoples (IPs) within the United Nations Framework Convention on Climate Change (UNFCCC). An analytical framework based on the extensive TEK and environmental management literature is developed, with a set of criteria identified against which to evaluate the platform. We find that although the process of designing the platform appears to be inclusive of Indigenous views, the structure itself does not recognize the …
