Biofuels From Crop Residue: Soil Organic Carbon And Climate Impacts In The Us And India, Adam Liska

Adam Liska Papers

The transformation of crop residue to soil organic carbon and CO₂ is a conserved process that occurs globally. Due to the mathematics of carbon intensity calculations found in government regulations, the amount of CO₂ emitted from crop residue per unit of energy in biofuel is largely independent of the amount of residue removed and the location of its removal, as shown by results from the US and India.

Soil organic carbon (SOC) levels are at equilibria determined by carbon inputs from plant material (+I_c) and loss from oxidation to CO₂

Are the US results relevant …

Improving The Accuracy For The Long-Term Hydrologic Impact Assessment (L-Thia) Model, Anqi Zhang, Lawrence Theller, Bernard A. Engel

The Summer Undergraduate Research Fellowship (SURF) Symposium

Urbanization increases runoff by changing land use types from less impervious to impervious covers. Improving the accuracy of a runoff assessment model, the Long-Term Hydrologic Impact Assessment (L-THIA) Model, can help us to better evaluate the potential uses of Low Impact Development (LID) practices aimed at reducing runoff, as well as to identify appropriate runoff and water quality mitigation methods. Several versions of the model have been built over time, and inconsistencies have been introduced between the models. To improve the accuracy and consistency of the model, the equations and parameters (primarily curve numbers in the case of this model) …

Acoustic Signatures Of Habitat Types In The Miombo Woodlands Of Western Tanzania, Sheryl Vanessa Amorocho, Dante Francomano, Kristen M. Bellisario, Ben Gottesman, Bryan C. Pijanowski

The Summer Undergraduate Research Fellowship (SURF) Symposium

The Miombo Woodlands of Tanzania comprise several habitat types that are home to a great number of flora and fauna. Understanding their responses to increasing human disturbance is important for conservation, especially in places where people depend so directly on their local ecosystem services to survive. Soundscapes are a powerful approach to study complex biomes undergoing change. The sounds emitted by soniferous fauna characterize the acoustic profile of the landscapes they inhabit such that habitats with the highest acoustic abundance are considered as the most diverse and possibly more ecologically resilient. However, acoustic variability within similar habitat types may pose …

Responses Of Agroecosystems To Climate Change: Specifics Of Resilience In The Mid-Latitude Region, Menas Kafatos, Seung Hee Kim, Chul-Hee Lim, Jinwon Kim, Woo-Kyun Lee

Mathematics, Physics, and Computer Science Faculty Articles and Research

This study examines the productivity and resilience of agroecosystems in the Korean Peninsula. Having learned valuable lessons from a Chapman University project funded by the United States Department of Agriculture which concentrated on the semi-arid region of southwestern United States, our joint Korea—Chapman University team has applied similar methodologies to the Korean Peninsula, which is itself an interesting study case in the mid-latitude region. In particular, the Korean Peninsula has unique agricultural environments due to differences in political and socioeconomic systems between South Korea and North Korea. Specifically, North Korea has been suffering from food shortages due to natural disasters, …

Gouldian Finch Breeding Surveys 2017: Ord-East Kimberley Expansion Project - Weaber Plain Development Area, Sarah R. Pryke

Irrigated Agricultural Development in the North

As part of the requirement for State approval under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) and the Gouldian Finch Management Plan (GFMP), a baseline assessment and on-going monitoring of the endangered Gouldian finch (Erythrura gouldiae) is required during the construction and operation of the Ord River Irrigation Area Weaber Plain Development Project in the eastern Kimberley, Western Australia. This report details the findings from surveys of Gouldian finches during their annual breeding season (2017).

Synergistic Use Of Remote Sensing And Modeling To Assess An Anomalously High Chlorophyll-A Event During Summer 2015 In The South Central Red Sea, Wenzhao Li, Hesham El-Askary, K. P. Manikandan, Mohamed A. Qurban, Michael J. Garay, Olga V. Kalishnikova

Mathematics, Physics, and Computer Science Faculty Articles and Research

An anomalously high chlorophyll-a (Chl-a) event (>2 mg/m3) during June 2015 in the South Central Red Sea (17.5° to 22°N, 37° to 42°E) was observed using Moderate Resolution Imaging Spectroradiometer (MODIS) data from the Terra and Aqua satellite platforms. This differs from the low Chl-a values (<0.5 mg/m3) usually encountered over the same region during summertime. To assess this anomaly and possible causes, we used a wide range of oceanographical and meteorological datasets, including Chl-a concentrations, sea surface temperature (SST), sea surface height (SSH), mixed layer depth (MLD), ocean current velocity and aerosol optical depth (AOD) obtained from different sensors and models. Findings confirmed this anomalous behavior in the spatial domain using Hovmöller data analysis techniques, while a time series analysis addressed monthly and daily variability. Our analysis suggests that a combination of factors controlling nutrient supply contributed to the anomalous phytoplankton growth. These factors include horizontal transfer of upwelling water through eddy circulation and possible mineral fertilization from atmospheric dust deposition. Coral reefs might have provided extra nutrient supply, yet this is out of the scope of our analysis. We thought that dust deposition from a coastal dust jet event in late June, coinciding with the phytoplankton blooms in the area under investigation, might have also contributed as shown by our AOD findings. However, a lag cross correlation showed a two- month lag between strong dust outbreak and the high Chl-a anomaly. The high Chl-a concentration at the edge of the eddy emphasizes the importance of horizontal advection in fertilizing oligotrophic (nutrient poor) Red Sea waters.

Effects Of Climate Warming On Net Primary Productivity In China During 1961–2010, Fengxue Gu, Yuandong Zhang, Mei Huang, Bo Tao, Rui Guo, Changrong Yan

Plant and Soil Sciences Faculty Publications

The response of ecosystems to different magnitudes of climate warming and corresponding precipitation changes during the last few decades may provide an important reference for predicting the magnitude and trajectory of net primary productivity (NPP) in the future. In this study, a process-based ecosystem model, Carbon Exchange between Vegetation, Soil and Atmosphere (CEVSA), was used to investigate the response of NPP to warming at both national and subregional scales during 1961–2010. The results suggest that a 1.3°C increase in temperature stimulated the positive changing trend in NPP at national scale during the past 50 years. Regardless of the magnitude of …

The Effects Of Isoprene Emission From Native And Invasive Trees On Local Air Quality, Aarti P. Mistry

DePaul Discoveries

Biogenic volatile organic compounds (BVOC) are the second-most abundant reactive gasses emitted into the atmosphere by the biosphere. Isoprene is a BVOC produced by the process of photosynthesis from vegetation and is emitted from plant leaves. Isoprene is a hydrocarbon that combines with oxides of nitrogen in the atmosphere to create ozone in the troposphere, an air pollutant. Invasive trees alter ecosystems and affect native tree populations. Invasive tree species in the Chicagoland area are outcompeting native tree species and expanding rapidly. The effect of isoprene emissions on air quality is a well-researched area in the atmospheric science community, however, …

Nuclear Weapons In A Changing Climate: Probability, Increasing Risks, And Perception, Adam Liska, Tyler R. White, Eric Holley, Robert J. Oglesby

Adam Liska Papers

Many people tend to think that the outcome of any nuclear weapons use today will result in an escalatory situation with apocalyptic outcomes for the countries involved. Yet many factors are increasing the probability of the limited use of nuclear weapons (e.g., 1 to 20 warheads) in a range of conflict scenarios. Previous atmospheric model simulations of regional nuclear conflicts employing many relatively small bombs have been estimated to cause a global “nuclear autumn,” with great reductions in agricultural productivity, stratospheric ozone loss, and spread of hazardous radioactive fallout. The totality of these effects would result in widespread damage …

The proposed building would supplement the evening and summer curriculum courses offered by the General Education Division (GED) in partnership with Portland State College and would become a vital resource for students in the Portland metropolitan area.

Bending The Carbon Curve: Fire Management For Carbon Resilience Under Climate Change, E. Louise Loudermilk, Robert M. Scheller, Peter J. Weisberg, Alec M. Kretchun

Environmental Science and Management Faculty Publications and Presentations

Context: Forest landscapes are increasingly managed for fire resilience, particularly in the western US which has recently experienced drought and widespread, high-severity wildfires. Fuel reduction treatments have been effective where fires coincide with treated areas. Fuel treatments also have the potential to reduce drought-mortality if tree density is uncharacteristically high, and to increase long-term carbon storage by reducing high-severity fire probability.

Objective: Assess whether fuel treatments reduce fire intensity and spread and increase carbon storage under climate change.

Methods: We used a simulation modeling approach that couples a landscape model of forest disturbance and succession with an ecosystem model of …

The Effect Of Salinity Acclimation On The Upper Thermal Tolerance Threshold Of The European Green Crab, Lauren S. Muñoz-Tremblay, A. L. Kelley, Catherine De Rivera

Environmental Science and Management Faculty Publications and Presentations

Fluctuations in salinity and temperature, among other varying environmental conditions, are stressors in estuaries and may work together to alter the physiological response of organisms that inhabit such environments. Laboratory assessments that investigate how animals respond to multiple environmental stressors can provide an ecological framework for understanding physiological performance across varying conditions. In this study, European green crabs, Carcinus maenas, were collected from Seadrift Lagoon, California, USA (37°54′27.82″N, 122°40′19.56″W) and were lab-acclimated at three different salinity concentrations typical of many estuaries: 15, 25, and 35 PSU at 12 °C (± 1 °C). After acclimation, crabs from each salinity treatment experienced …

Fossil Fuel Asset Risk Analysis: Clark University Endowment, Travis A. Dodge, B. Maiwand Akbari

Student Works

The environmental and social risks of climate change are well known and perhaps inevitable. The economic and financial risks are less so. The many financial risks associated with climate change embedded in endowment portfolio fossil fuel holdings are leading many institutional stakeholders to enter into dialogue and take action. Divestment is emerging as an effective strategy for limiting portfolio exposure and tackling climate change itself.

Our team’s goals were to assess whether the Clark University endowment portfolio faces any of these risks and evaluate the impacts on asset values. Our findings show that the Clark endowment does face these same …

Sustainability Assessment Of U.S. Beef Production Systems, Greg Thoma, Ben Putman, Marty Matlock, Jennie Popp, Leah English

Food Systems

With increasing public concern and awareness of agricultural sustainability issues, comprehensive methodologies such as life cycle assessment are required to benchmark the beef industry and identify areas of opportunity for continuous improvement. To that end, the Beef Checkoff completed a retrospective sustainability assessment benchmark in 2013 by using Eco-efficiency analysis to compare the years 2005 and 2011. At the time of the analysis, the methodology used was the most up-to-date and comprehensive – indeed the analysis remains one of the only complete cradle-to-grave assessments of the U.S. beef industry. In 2015, a further refined version of the Eco-efficiency analysis was …

Influence Of The Interaction Of Calcium Carbonate Particles With Surfactants On The Degree Of Water Pollution In Small Rivers, Petry Spataru, Francisco Fernandez, Joseph W. Sista, Tudor Spataru, Oxana Spinu, Igor Povar

Publications and Research

Introduction: The influence of the interaction of calcium carbonate (CaCO3) and surface-active substances (SAS; surfactants) with different chain lengths and cationic and anionic hydrophilic centers has been analyzed.

Results: Laboratory simulations indicate reduced negative influences on cationic SAS nitrification/self-purification processes in the presence of anionic species. This suggests the role of complex ionic formation [anionic SAS * cationic SAS] as a cause of this effect. UV-Vis spectra of lauryl sulfate (LS) and of cetyltrimethylammonium (CTMA), as well as of their mixtures in ratios of 2:1 and 1:1, treated by fine particles of CaCO3, display decreased amounts of SAS in analyzed …

Economic Evaluation Of Coastal Land Loss In Louisiana, Stephen R. Barnes, Craig Bond, Nicholas Burger, Kate Anania, Aaron Strong, Sarah Weilant, Stephanie Virgets

Journal of Ocean and Coastal Economics

Louisiana has lost approximately 1,880 square miles of land over the past eighty years. Projections suggest that in a future without action, the next fifty years could result in the loss of 1,750 additional square miles of land area. As land loss continues, a large portion of the natural and man-made capital stocks of coastal Louisiana will be at greater risk of damage, either from land loss or from the associated increase in storm damage. We estimate the replacement cost of capital stock directly at risk from land loss ranges from approximately $2.1 billion to $3.5 billion with economic activity …

Silicon Valley is the San Francisco Bay Area’s economic powerhouse and is herald for its innovation and success. However, Silicon Valley’s urban design is unsustainable and characterized by remote and large corporate campuses that contribute to job sprawl and heavy traffic congestion. Many of the buildings are also not performing at an efficient level and are due for deep overhauls to cut back energy consumption and costs. The inevitable effects of climate change continue to loom large over the world, heightening the importance for the built environment to be reformed into an environment that can mitigate and adapt to climate …

Embodied Carbon: A Framework For Prioritizing And Reducing Emissions In The Building Industry, Natalie C. Wheating

Master's Projects and Capstones

Global climate change is one of the most impactful environmental issues in modern times, and the construction industry is known to be one of the largest contributors to carbon emissions—one of the key causes of climate change. Embodied carbon emissions of buildings are an often overlooked, but significant, influencer of a building’s overall carbon footprint. This gives rise to the need for improved life cycle analysis of buildings and identification of opportunities to reduce the total carbon footprint of a building throughout its life cycle. This paper analyzes the current state of the building industry that limits the consideration of …

Landowner And Practitioner Perspectives On Private Land Conservation Programs, Michelle L. Lute, Caitlyn R. Gillespie, Dustin R. Martin, Joseph J. Fontaine

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Efforts to reverse declines in native grasslands benefit from agricultural policies that encourage private land conservation. The U.S. Department of Agriculture’s Conservation Reserve Program (CRP) improved conservation across landscapes but enrollment has declined. We used sequential exploratory mixed methods to compare landowner and conservation practitioners’ perceptions, evaluate perceived benefits, and identify potential improvements to CRP. Focus groups of practitioners informed a quantitative survey of landowners who had properties >160 total acres in Nebraska. Results suggest potential misalignment in perceptions between practitioners and landowners. Practitioners were concerned that conservation, especially of wildlife, was secondary to profit. But the majority of landowners …

The Limitation Of Spread Of Non-Native Marine Invertebrates From Artificial Structures To Natural Habitats, Whitney Mcclees, Catherine E. De Rivera

ESM Colloquium

Artificial structures created for aquatic anthropogenic activities are often colonized and fouled by many non-native species, few of which have invaded natural areas. Some research has indicated predation is limiting the spread of non-native species, while other research has indicated that it is dispersal-driven. To determine the effects of dispersal limitation and predation on the risk to surrounding habitats of being invaded by non-native species established on marina docks, we used a three-factor design, deploying seven unglazed ceramic panels per each treatment combination of 1) inside versus outside a marina in Yaquina Bay, Oregon; 2) cage keeping out predators >mesh …
