Negative Impacts Of The Beef Industry: Lab-Grown Meat, Stephanie Grass Aug 2019

Negative Impacts Of The Beef Industry: Lab-Grown Meat, Stephanie Grass

WRIT: Journal of First-Year Writing

The beef industry is harmful to the environment and human health and alternative solutions must be implemented in order to mitigate the effects of climate change. Water and grain are used in agriculture in abundance despite the negative environmental effects it causes. Cattle are the biggest contributors to greenhouse gas emissions in the sector, also contributing to climate change. Antibiotics are used in large quantities without regard to potential future consequences. One potential solution for this problem is lab-grown beef, which demands very little from the consumer and would take pressure off the environmental issues the beef industry creates. Lab-grown ...


High And Low Management Input Regimes Result In Similar Net Carbon Sequestration Rates In Zoysiagrass Golf Course Fairway Turf, Ross C. Braun, Dale J. Bremer Jan 2019

High And Low Management Input Regimes Result In Similar Net Carbon Sequestration Rates In Zoysiagrass Golf Course Fairway Turf, Ross C. Braun, Dale J. Bremer

Kansas Agricultural Experiment Station Research Reports

This study was conducted from 2013–2016 to determine how irrigation and N fertilization may be managed to enhance carbon (C) sequestration in turf. In this study, the annual rate of change in soil organic carbon (ΔSOC) was measured under two management regimes, a high management input regime (HMI) and low man­agement input regime (LMI), in a ‘Meyer’ zoysiagrass (Zoysia japonica Steud.) golf course fairway.

Both management regimes maintained acceptable turf quality and at least 75% green cover during both summers. In both management regimes, soil organic carbon (SOC) increased after the 3.16-yr (1154-d) period indicating that C ...


Herbarium Records Reveal Earlier Bloom Times In Three Southern Appalachian Plant Species, Melanie Flood, Mark Davis, Ashlee Mccaskill Aug 2018

Herbarium Records Reveal Earlier Bloom Times In Three Southern Appalachian Plant Species, Melanie Flood, Mark Davis, Ashlee Mccaskill

Georgia Journal of Science

Plant phenology, especially the onset of flowering in angiosperms, is a useful tool for studying the effects of climate change on native flora because it is influenced by temperatures. Numerous studies in different biomes have provided evidence of earlier bloom times in response to increasing temperatures. We examined herbarium specimen data to determine whether three spring-blooming species (Sanguinaria canadensis, Iris cristata, and Trillium rugelii) at the southern terminus of the Appalachians exhibit a similar change in onset of flowering over several decades. All three species exhibited significantly earlier flower onset during the past 120 years, a change that could have ...


Nitrous Oxide Emissions And Carbon Sequestration In Turfgrass: Effects Of Irrigation And Nitrogen Fertilization (Year 2), R. Braun, D. Bremer Jul 2017

Nitrous Oxide Emissions And Carbon Sequestration In Turfgrass: Effects Of Irrigation And Nitrogen Fertilization (Year 2), R. Braun, D. Bremer

Kansas Agricultural Experiment Station Research Reports

This study was conducted from 2013–2016 to determine how irrigation and N fertilization may be managed to reduce N2O emissions and enhance carbon sequestration. In this study, annual nitrous oxide (N2O) emissions were greatest in urea and the least in unfertilized (no N) among treatments. During summer, the lower irrigation treatment resulted in less N2O emitted. All fertilizer and irrigation treatments maintained acceptable quality and high levels of percent green cover; however, the controlled-release fertilizer resulted in more consistent turf quality and green cover compared to urea and unfertilized. Urea fertilizer had higher ...


Combinatory Effect Of Changing Co2, Temperature, And Long-Term Growth Temperature On Isoprene Emissions, Michael Cole Jul 2016

Combinatory Effect Of Changing Co2, Temperature, And Long-Term Growth Temperature On Isoprene Emissions, Michael Cole

DePaul Discoveries

Isoprene, the most abundant hydrocarbon in the atmosphere, plays a significant role in atmospheric chemistry. Its reactions with NOx lead to the formation of ozone in the lower troposphere, which is harmful to plants and detrimental to human health. As air temperatures and CO2 concentrations increase with climate change, it is uncertain how isoprene emissions from plants will respond. We hypothesized that isoprene emissions will increase with the combination of increasing temperature and CO­2 concentrations. We predict that oaks grown at a higher temperature will exhibit an increase in isoprene emissions with combined short-term increases in temperature ...


Nitrous Oxide Emissions And Carbon Sequestration In Turfgrass: Effects Of Irrigation And Nitrogen Fertilization (Year 1), R. Braun, D. Bremer, J. Fry Jan 2016

Nitrous Oxide Emissions And Carbon Sequestration In Turfgrass: Effects Of Irrigation And Nitrogen Fertilization (Year 1), R. Braun, D. Bremer, J. Fry

Kansas Agricultural Experiment Station Research Reports

In this study, annual nitrous oxide (N2O) emissions were greatest in urea and least in untreated (no N) among treatments. Differences were negligible due to irrigation treatment. Irrigation levels may be decreased further in the final year to induce slight stress on the low irrigation treatment. All fertilizer treatments maintained acceptable quality, however the controlled-release fertilizer resulted in more consistent visual quality ratings compared to urea and untreated. Urea fertilizer had higher peak fluxes after fertilization and overall annual emissions than polymer-coated N-fertilizer. Thus, controlled released N fertilizers, such as polymer-coated urea, in turfgrass systems could potentially help ...


Enhancement Of The Role Of Spatial Planning In Climate Change Adaptation By Long Term Modelling Of Land Use Change In Hungary, Krisztián Schneller, Erzsébet Vajdovich Visy, Vilja Vaszócsik Jan 2016

Enhancement Of The Role Of Spatial Planning In Climate Change Adaptation By Long Term Modelling Of Land Use Change In Hungary, Krisztián Schneller, Erzsébet Vajdovich Visy, Vilja Vaszócsik

Proceedings of the Fábos Conference on Landscape and Greenway Planning

The purposeful formation of land use significantly contributes to the moderation of the adverse impact of climate change. Since spatial planning plays a fundamental role in the formation of land use, therefore it is essential to integrate climate adaptation goals into the planning process (Biesbroek, G.R. et al., 2009). Spatial plans primarily assist the achievement of adaptation purposes by the delimitation and protection (primarily against urban sprawl) of areas (as zones, such as ecological corridors) which are important in adaptation and risk prevention. In Hungary at present the spatial planning system already contribute to the above mentioned objectives, but ...


Sustainable Urban Planning And Climate Change Scenarios: An Investigation Of Staten Island's Urban Planning, Melissa Wagner, Lauren E. Gentile, Joanna Merson, Elizabeth Wentz Jan 2016

Sustainable Urban Planning And Climate Change Scenarios: An Investigation Of Staten Island's Urban Planning, Melissa Wagner, Lauren E. Gentile, Joanna Merson, Elizabeth Wentz

Proceedings of the Fábos Conference on Landscape and Greenway Planning

Recent events like Hurricane Sandy, which struck Staten Island, NY on October 29, 2012, serve as a costly reminder of how unsustainable designs and mounting social pressures can contribute to extensive structural damage and subsequent financial cost, from storm surge inundation and coastal flooding. It is unlikely that Hurricane Sandy was a one-time event but rather a warning of what can occur over the next century without proper mitigation strategies. Based on climate change projections, such extreme events are expected to become more frequent and intense due to warmer sea surface temperatures and rising sea levels (Emmanual, 2005; Kirtman et ...

The Influences Of Poultry Litter Biochar And Water Source On Radish Growth And Nutrition, Julia Allen, David E. Longer, Edward E. Gbur, Lichen Hao

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Many row-crop fields today have declined in soil fertility due to poor management practices and overuse of pesticides. Under these conditions, plant nutrient uptake can be sub-optimal. There are several soil amendments that can be used to improve soil quality and plant growth. This study focused on the addition of biochar to the soil and the use of structured water to enhance plant growth. Biochar is produced by pyrolysis of organic feedstocks. Previous studies which focused on biochar have shown an increase in plant yield, nutrient availability in the soil, and soil water holding capacity. Structured water is the liquid ...


Assessment Matrix Based Evaluation Of Ecosystem Services In Relation To Land Use Change Scenarios, Gergő Gábor Nagy, Veronika Magyar, Sándor Jombach, László Kollányi, Balázs Duray Jan 2013

Assessment Matrix Based Evaluation Of Ecosystem Services In Relation To Land Use Change Scenarios, Gergő Gábor Nagy, Veronika Magyar, Sándor Jombach, László Kollányi, Balázs Duray

Proceedings of the Fábos Conference on Landscape and Greenway Planning

The ecosystem services are natural assets and services, which are used by humans directly or indirectly over their respective lifetimes (MEA, 2005). Several authors and organizations describe these goods of nature in different ways. Some authors use ecological concepts as the basis for categorization (Norberg, 1999), others concentrate on different human needs (Wallace, 2007), however the most common categories are based on some functional distinction (MEA, 2005; de Groot, 2006; Hein et al., 2006). Authors representing this latter group usually mention the following classification: provisioning, regulating, supporting and cultural services. The provisioning services like water, wood or timber are used ...


Effects Of Detention For Flooding Mitigation Under Climate Change Scenarios— Implication For Landscape Planning In The Charles River Watershed, Massachusetts, Usa, Chingwen Cheng, Elizabeth A. Brabec, Yi-Chen E. Yang, Robert L. Ryan Jan 2013

Effects Of Detention For Flooding Mitigation Under Climate Change Scenarios— Implication For Landscape Planning In The Charles River Watershed, Massachusetts, Usa, Chingwen Cheng, Elizabeth A. Brabec, Yi-Chen E. Yang, Robert L. Ryan

Proceedings of the Fábos Conference on Landscape and Greenway Planning

Climate change has posed increased risks to environmental hazards (e.g., flooding, droughts, hurricanes) in addition to new challenges under climate change impacts (e.g., early snow melt, sea level rises, heat waves). Floods are omnipresent in almost every city in the United States and account for the most economic losses than any other single geophysical hazard (White and Haas 1975). Previous climate change studies have suggested promising trends of increasing temperature and changing precipitation patterns as well as increased intensity and duration of storm events that are likely to result in more flooding events in the Northeast region. Flooding ...


Greenways In Strategies Of Mitigation And Adaption To Climate Change: Case Study Of State Of Maryland, Usa, David Myers Jan 2010

Greenways In Strategies Of Mitigation And Adaption To Climate Change: Case Study Of State Of Maryland, Usa, David Myers

Proceedings of the Fábos Conference on Landscape and Greenway Planning

This paper, using the State of Maryland, USA as a case study, draws connections between greenway contributions to the Greenprint Program in MD and the rapidly expanding work on the use of green infrastructure to address climate change. It focuses on recent initiatives that could support the role of greenways in mitigating and adapting to climate change. Maryland established the Climate Change Commission in April 2007 by executive order to develop a plan for reducing the state’s vulnerability to sea level rise and other impacts of climate change. The Maryland Climate Change Commission's Climate Action Plan documented fortytwo ...


Blueprints For Green Communities: Climate Change Visioning And Participatory Landscape Planning For Resilient Low-Carbon Communities, David N. Flanders, Stephen R.J. Sheppard, Ellen Pond, Sarah Burch, Alison Shaw, Stewart Cohen Jan 2010

Blueprints For Green Communities: Climate Change Visioning And Participatory Landscape Planning For Resilient Low-Carbon Communities, David N. Flanders, Stephen R.J. Sheppard, Ellen Pond, Sarah Burch, Alison Shaw, Stewart Cohen

Proceedings of the Fábos Conference on Landscape and Greenway Planning

Emerging 3D visualization tools and future visioning methods offer new ways to make climate change impacts and potential responses explicit, and accelerate holistic solutions. Previous research at UBC’s Collaborative for Advanced Landscape Planning (CALP) and elsewhere confirms that 4D visioning processes using landscape visualizations of recognizable places under alternative future conditions can improve community engagement and awareness on complex environmental and planning issues (Tress and Tress, 2002; Sheppard and Meitner, 2005; Schroth, 2007). This paper examines a visioning process (Sheppard, 2008) that applies visualization and other landscape planning methods to explore high and low-carbon futures of the affluent, sub-urban ...
