681. Influence Of The Enabling Environment On Drinking-Water Programs: Qualitative And Quantitative Analyses

Title Tesim:: Influence Of The Enabling Environment On Drinking-Water Programs: Qualitative And Quantitative Analyses
Creator:: Ojomo, Edema

Date of publication:: May 2016
Abstract Tesim:: Accounting for drinking-water quality, approximately 1.8 billion people lack access to safe drinking-water, increasing their risk of diarrheal diseases. To remedy this, Sustainable Development Goals, particularly target 6.1 to “achieve universal access to safe and equitable water” by 2030, were established. It is believed achieving this will require an enabling environment. However, the enabling environment for drinking-water programs is ill-defined. The term “enabling environment” is increasingly used in the drinking-water field but its meaning is vague and its influence on drinking-water programs has not been determined. The purpose of this dissertation is to clarify the meaning of the enabling environment and investigate its influence on drinking-water programs. I use the institutional analysis and development framework to explain the enabling environment. Key informant interviews are carried out to determine the influence of the enabling environment on drinking-water programs, specifically household-water treatment and safe storage (HWTS) programs and climate change adaptation of drinking-water systems. Additionally, multiple regression analyses are conducted to determine the significance of enabling environment variables on expenditures on drinking-water systems, a proxy for decision-making about providing access to drinking-water. I find that the enabling environment is the blend of formal rules, informal rules, and the physical environment that impact the capacity of individuals and organizations to achieve their objectives. All enabling environment elements—formal rules, informal rules, and the physical environment—were found to influence the drinking-water programs analyzed; however, their relative degree of influence varied. In the HWTS study, informal rules (e.g. cultures), were found to determine adoption of HWTS practices more than formal rules (e.g. policies). Formal rules had a greater impact on decisions to adapt drinking-water systems to climate change than informal rules. Formal and informal rules about partnerships were a recurrent theme in both studies. Regression analyses showed that policies supporting user participation and cross-sectoral partnerships had significant effects on expenditures on drinking-water systems regardless of rural or urban setting. I show that actors involved in drinking-water programs will benefit from shaping an enabling environment that facilitates access to drinking-water. This enabling environment will resemble one that is collaborative with clearly defined leadership.

682. STREAMFLOW TRENDS AND DROUGHT IN THE SOUTH ATLANTIC, U.S.: IMPLICATIONS FOR WATER MANAGEMENT AND WATER TRANSFERS

Title Tesim:: STREAMFLOW TRENDS AND DROUGHT IN THE SOUTH ATLANTIC, U.S.: IMPLICATIONS FOR WATER MANAGEMENT AND WATER TRANSFERS
Creator:: Patterson, Lauren Anne
Date Created:: February 13, 2015
Date of publication:: May 2012
Abstract Tesim:: The South Atlantic has recently experienced region-wide droughts. There is concern that water scarcity may become more common or prevalent due to a warming climate. Problems associated with water scarcity are compounded by under-developed water allocation policy in the historically water abundant South Atlantic. This dissertation examined the potential causes of water scarcity related to changes in average streamflow from 1934-2005, 1934-1969 (Mid-20th Century) and 1970-2005 (Late-20th Century). Second, the contribution of climate versus anthropogenic drivers of change in mean annual streamflow in the Late 20th Century was evaluated using Budyko curves. Third, hydrologic drought was characterized in the South Atlantic and changes in drought characteristics were assessed over multiple time periods. Fourth, water interconnections, which form an important component of water infrastructure and water management, were assessed for the potential to transfer water from a drought free to a drought stricken area. Results showed that streamflow abruptly shifted from a drier regime in the Mid-20th Century to a wetter regime in the Late-20th Century with trends of significantly decreasing streamflow since 1970. Climate contributed to increased streamflow during the Late-20th Century throughout the South Atlantic; whereas human factors varied between basins and either amplified or decreased the climate change effect on streamflow. Human impacts were equivalent to or exceeded climate impacts in some basins. Seventy-one percent of drought events were shorter than 6 months with a recurrence interval of 6 years. Less than 7% of droughts were longer than one year, yet these longer duration droughts resulted in region-wide water scarcity. There were few significant temporal trends in drought characteristics over the studied time periods. The short interconnection distances (median=11.6 km) rarely extended beyond the spatial extent of multi-year droughts; interconnected water systems were simultaneously in drought 98±3% of the time from 2000-2008. Water managers face many challenges with a steadily growing demand and fluctuating long-term and short-term water supply needs that can be partially met through interconnections. Decision-making will benefit from monitoring changes in climate, human activities, and streamflow, as well as continually assessing the ability of current water infrastructure to perform under normal and adverse conditions.

683. Influence of hydrology and denitrification on nutrient dynamics in coastal headwater streams

Title Tesim:: Influence of hydrology and denitrification on nutrient dynamics in coastal headwater streams
Creator:: McMillan, Sara Kristen
Date Created:: October 19, 2010
Date of publication:: August 2007
Abstract Tesim:: Watershed-derived nitrogen (N) inputs from coastal watersheds can have a significant impact on estuarine function, with land use and stream network characteristics altering the timing, quantity and quality (labile vs. refractory) of this source. Excess N in estuarine ecosystems has led to increased rates of primary production (eutrophication), reduced biodiversity, habitat degradation and food web alterations. Nitrogen retention is particularly high in shallow headwater streams due to high biological activity, increased sediment surface to streamwater volume ratios and the fact that low order streams encompass a large proportion of total stream length within the stream network. Denitrification is one component of instream N retention that is particularly important because it removes N from the aquatic ecosystem. Two coastal plain watersheds of contrasting land uses (agricultural and silvicultural) located adjacent to the Neuse River Estuary were studied to assess the effect of hydrology on nutrient export, the factors controlling rates of denitrification in streambed sediments and the contribution of denitrification to instream N removal. Nitrate export was greatly affected by hydrodynamic conditions, with nutrient pulses observed during storm events, often increasing instream concentrations by 1-2 orders of magnitude. Factors that controlled denitrification varied by land use. Nitrate, organic carbon and elevated temperature stimulated rates in agricultural streams, but had minimal impact in silvicultural streams. Instream nutrient retention determined by mass balance calculations showed the stream to be a significant sink for ammonium (46%) and phosphate (14%), but not nitrate. High rates of denitrification observed in the agricultural sediments following nitrate additions showed significant potential for denitrification, which responded linearly to increasing nitrate concentrations. However, the ability of denitrification to attenuate storm pulses of nitrate depends largely on hydrological transport of nitrate-rich streamwater to denitrifying communities in streambed sediments. Management of these drainage networks, including channel modifications to increase hyporheic flow (i.e. addition of woody debris or other channel obstructions) or to increase retention time (i.e. flashboard risers or streamside wetlands) may help reduce downstream export in streams that support high rates of denitrification.

684. Sequence stratigraphy of the marginal marine facies of the Jurassic Sundance Formation, South Dakota and Wyoming: implications for controls of higher-order cyclicity in a greenhouse world

Title Tesim:: Sequence stratigraphy of the marginal marine facies of the Jurassic Sundance Formation, South Dakota and Wyoming: implications for controls of higher-order cyclicity in a greenhouse world
Creator:: Bossenbroek, Karen Elaine
Date Created:: March 18, 2013
Date of publication:: December 2011
Abstract Tesim:: The Sundance Formation was produced by three marine inundations of the Western Interior during the Mesozoic, and the passive margin sediments are exposed in the Black Hills region of Wyoming and South Dakota. This study applies sequence-stratigraphic principles in correlation of geophysical well-log data and measured outcrops to establish a chronostratigraphic framework, in order to identify possible processes that govern stratigraphic architecture. The Sundance is part of a higher-order trend of marine inundations on the Western Interior governed by 3rd order cyclicity. The stratigraphy of the Lower Sundance displays a long-term trend of transgression and regression, punctuated by multiple parasequences. High-frequency variation in stratal architecture observed was likely shaped by cyclic variation in sediment supply governed by climate change. This study supports the current view that eustacy during greenhouse intervals is governed by low-frequency slow variations, and higher-frequency short-order cyclicity in sedimentation may also be superimposed during these long-term intervals.

685. SELF-ORGANIZATION OF THE CLIMATE SYSTEM: SYNCHRONIZED POLAR AND OCEANIC TELECONNECTIONS

Title Tesim:: SELF-ORGANIZATION OF THE CLIMATE SYSTEM: SYNCHRONIZED POLAR AND OCEANIC TELECONNECTIONS
Creator:: Reischmann, Elizabeth
Date Created:: June 30, 2017
Date of publication:: December 2016
Abstract Tesim:: Synchronization is a widespread phenomenon in nonlinear, physical systems. It describes the phenomena of two or more weakly interacting, nonlinear oscillators adjust their natural frequencies until they come into phase and frequency lock. This behavior has been observed in biological, chemical and electronic systems, including neurons, fireflies, and computers, but has not been widely studied in climate. This thesis presents a study of several major examples of synchronized climatic systems, starting with ice age timings seemingly caused by the global climate’s gradual synchronization to the Earth’s 413kyr orbital eccentricity band, which may be responsible for the shift of ice age timings and amplitudes at the Mid-Pleistocene transition. The focus of the thesis, however, is centered the second major example of stable synchronization in the climate system: the continuous, 90 degree phase relationship of the polar climate signals for the entirety of the available ice record. The existence of a relationship between polar climates has been widely observed since ice core proxies became available in both Greenland and Antarctica. However, my work focuses on refining this phase relationship, utilizing it’s linear nature to apply deconvolution and establish an energy transfer function. This transfer function shows a distinctly singular frequency, suggesting that climate signal is predominately communicated north to south with a period of 1.6kyrs. This narrows down possible mechanisms of polar connection dramatically, and is further investigated via a collection of intermediate proxy datasets and a set of more contemporary, synchronized, sea surface temperature dipoles. While the former fails to show any strong indication of the nature of the polar signal due in part to the overwhelming uncertainties present on the centennial and millennial scales, the latter demonstrates a large set of synchronized climate oscillations exist, communicate in a variety of networks, and have a direct connection to larger climate patterns (in this case, precipitation anomalies). Overall, this thesis represents a clear advance in our understanding of global climate dynamics, presents a new method of climate time series analysis, evidence of 16, stable, synchronized sea surface temperature dipoles, and provides a detailed sediment core database with explanations of age model limitations for future investigation.

686. Factors Regulating Methane Production and Oxidation in Two Shallow Arctic Alaskan Lakes

Title Tesim:: Factors Regulating Methane Production and Oxidation in Two Shallow Arctic Alaskan Lakes
Creator:: Lofton, Dendy D.
Date Created:: February 14, 2015
Date of publication:: August 2012
Abstract Tesim:: Methane (CH4) is second only to CO2 as a greenhouse gas and is produced in the terminal step of organic matter decomposition in anaerobic environments, including lake sediments. Given the widespread distribution of lakes in Arctic Alaska, CH4 emission from these lakes may significantly contribute to the atmospheric CH4 budget. Aerobic methane oxidizing bacteria consume CH4 diffusing from anaerobic zones of production, thereby modulating the flux of CH4 to the atmosphere. Multiple research efforts indicate a significant source strength for arctic environments in the atmospheric CH4 budget. Predicted climate induced alterations to the arctic landscape include increased organic matter loading from the terrestrial environment and increased temperature. These environmental changes can influence both rates of CH4 production and oxidation, possibly altering rates of CH4 exchange between shallow arctic lakes and the atmosphere. I assessed rates and controls on CH4 production and oxidation in two shallow arctic lakes to provide insight into the response of these two microbial groups to projected future climates. Rates of total methanogenesis and the fractional contribution of the acetoclastic pathway decreased with increasing depth below the sediment surface to 5 cm in both lakes. Substrate additions indicated substrate limitation to both methanogenic pathways (acetoclastic and hydrogenotrophic). Rates of total methanogenesis varied spatially in the horizontal dimension in one lake only. However, there was no consistent relationship between rates of methanogenesis and depth of the overlying water as labile organic matter in the shallow sediments are likely resuspended and deposited unevenly by wind action. Under extant conditions, rates of methanogenesis responded positively to increases in temperature, while rates of CH4 oxidation remained unchanged. The former were controlled by substrate x temperature interactions, while the latter were regulated strictly by substrate supply. Analysis of CH4 oxidation kinetics for water samples points to a community of CH4 oxidizing bacteria that is capable of oxidizing CH4 at concentrations far in excess of observed levels. Increases in organic matter supply and temperature under future climates will likely increase rates of methanogenesis, but the impact may be fully mitigated by the excessive capacity of the CH4-oxidizing community to process the added substrate.

687. Paleoclimate archives and evolutionary patterns preserved in neogene scallop shells: implications for linking climate change, paleobiogeography, and morphologic evolution of Chesapecten along the Atlantic coastal plain, USA

Title Tesim:: Paleoclimate archives and evolutionary patterns preserved in neogene scallop shells: implications for linking climate change, paleobiogeography, and morphologic evolution of Chesapecten along the Atlantic coastal plain, USA
Creator:: Goewert, Ann Elizabeth
Date Created:: March 18, 2013
Date of publication:: August 2010
Abstract Tesim:: Models of future climate predict a 2 to 4.5 degree Celsius increase in global temperature by the 21st century with uncertain consequences on evolution, ecology, and geographic distribution of organisms. This work combines geochronology, paleoclimatology, and paleoecology/evolution to assess variation in geographic patterns of global warming in the recent geologic past and its effects on the evolution, ecology, and biogeography of Chesapecten. Neogene sediments from the US Atlantic Coastal Plain yield deposits that mark the last two episodes of globally warm climates (i.e., Mid Miocene Climate Optimum (MMCO) and the Middle Pliocene Warm Interval (MPWI)) and serve as analogues of future warming. The following studies employ shells of Chesapecten to reconstruct morphologic evolution and seasonality. The genus Chesapecten is a morphologically complex group comprising seven nominal species in the Miocene and Pliocene of the U.S. Atlantic Coastal Plain. Species of Chesapecten were originally defined as a morphostratigraphic species (i.e., characterized by morphology and by gaps or hiatuses in deposition). The first chapter uses multivariate and descriptive statistics to: 1) determine the number and nature of true morphotaxa of Chesapecten (i.e., species defined solely by morphology), 2) nomenclatorially reconcile these morphotaxa with previously named nominal species, and 3) evaluate the biostratigraphic significance of the morphotaxa. This study demonstrates the existence of one novel morphogenus and two morphosubgenera of Chesapecten and emends the traditional systematics of Chesapecten. Morphostratigraphic species are distinguishable only when a species by stratum analysis is conducted. In the second chapter, seasonal temperatures are reconstructed along a meridional (~27 to 37 degree N) and biogeographic gradient during the MMCO and MPWI to test whether global warming shifts biogeographic provenances northward. This study reports diminished seasonality and expansion of the tropical biogeographic province to mid latitudes during the MMCO and increased seasonality and expansion of the warm temperature province in mid latitudes during the MPWI. The third chapter evaluates whether mid latitude MPWI shells form annual growth increments. MPWI shells from the warm temperate province form winter growth lines contrary to modern bivalves. This dissertation provides a glimpse into Neogene seasonality during warm climates and is pivotal to understanding ecological and evolutionary responses to future warming.

688. Sediment Emission and Water Column Oxidation of Methane in Alaskan Arctic Lakes

Title Tesim:: Sediment Emission and Water Column Oxidation of Methane in Alaskan Arctic Lakes
Creator:: McGowan, Gabriel E.
Date Created:: February 14, 2015
Date of publication:: August 2012
Abstract Tesim:: Methane (CH4) is a greenhouse gas and is important in lacustrine food webs. Cycling of CH4 in arctic lakes is poorly quantified, though arctic wetlands are key to the atmospheric CH4 budget. Sediment emission and water column oxidation of CH4 were studied in 3 shallow and 3 deep Alaskan arctic lakes during the 2010 and 2011 thaw seasons. Sediment CH4 emission was oxygen-regulated and significantly higher in shallow lakes, averaging 1.39 mmol m-2 d-1. Methane comprised a larger fraction of sediment catabolism in shallow lakes. Water column CH4 oxidation was significantly greater in shallow lakes, averaging 0.16 mmol m-2 d-1, with specific rates in bottom waters among the highest reported. Air-water CH4 exchange ranged up to 1.94 mmol m-2 d-1 in shallow lakes, similar to rates reported for tropical lakes. The data show that CH4 is important in C cycling in shallow Alaskan arctic lakes, which emit considerable CH4 despite extensive CH4 oxidation.

689. NATURAL AND ANTHROPOGENIC DRIVERS OF OYSTER REEF COMMUNITY DYNAMICS

Title Tesim:: NATURAL AND ANTHROPOGENIC DRIVERS OF OYSTER REEF COMMUNITY DYNAMICS
Creator:: Tice-Lewis, Maxwell
Date Created:: August 23, 2018
Date of publication:: August 2018
Abstract Tesim:: Understanding how natural and anthropogenic alterations to local abiotic conditions influence oyster reef distribution and associated community assembly is critical to achieving conservation and restoration goals. Between 2013-2015, we surveyed 6 intertidal and 5 subtidal oyster reefs encompassing salinity gradients in two estuaries, measured salinity and temperature, and culled historical salinity records to determine the relative importance of tidal emersion, salinity, and temperature on oyster communities and multidecadal changes to oyster community variability. We found tidal emersion was the most important driver of differences in oyster density, species richness, and community structure followed by salinity. We found that channel dredging and sea level rise have likely caused a multidecadal trend in rising salinity in the Newport River Estuary, and decreases in spatial community turnover on oyster reefs between Wells (1961) and our surveys. This has resulted in a “coastal squeeze” in oyster community spatial variability and oyster cultivation area.

Abstract Tesim:: The cash crop cotton has been suggested as a cause of the unexpectedly high malnutrition rates in the Sikasso region of Mali. This paper tests that hypothesis as well as two of the proposed pathways by which cotton has been suggested to cause malnutrition: through worsening diets and though reduced ecosystem services from soil degradation and agricultural extensification. Both household surveys and region scale satellite imagery combined with Demographic and Health Surveys suggest that there is an association between cotton cultivation and malnutrition. However, there was no evidence that cotton cultivationisrelatedtoworseneddietsormalnutritionatahouseholdlevel. Rather,cotton cultivation, reduced biodiversity and malnutrition are all associated at a village level, indicating that the environmental effects of cotton cultivation may be causing associated malnutrition through reduced ecosystem services.
