Green Building Business Is Booming, Richard Snow, Mary Snow

Publications

Shelter is one of life’s basic necessities. However, according to the U.S. Department of Energy, residential and commercial buildings account for nearly 40% of the total carbon dioxide (CO2) released in the United States annually [1]. The percentage is even higher in China, which leads the world in CO2 emissions from buildings. Most of this CO2 comes from burning fossil fuels to provide the energy necessary to cool, heat, and light homes, office buildings, and retail space. CO2 emissions from residential and commercials buildings are forecast to increase more than emissions from any other sector over the next 25 years. …

Dynamics Of Wild Red Raspberry (Rubus Idaeus L.) And The Influence On Tree Regeneration Within Silvicultural Openings In A Northern Hardwood Stand, Matthew J. Widen

Dissertations, Master's Theses and Master's Reports

Previous studies have investigated how the abundance of raspberries (Rubus idaeus L.) impacts tree regeneration, but few have linked these impacts to location within canopy openings with a legacy tree. To fill this knowledge gap, we investigated the presence, abundance, and location of raspberries within openings containing legacy trees and the resulting impacts on tree regeneration. During the winter of 2003, 49 openings were created of three sizes: small, medium, large and 20 reference single-tree selection sites in a northern hardwood stand in Ford Forest near Alberta, Michigan. Tree regeneration and vegetative species cover were recorded in 2005 and …

The Effects Of Early Pruning On The Near-Ground Branch Density Of Four Live Fencing Species, Aric Devens

Dissertations, Master's Theses and Master's Reports

Crop losses in home gardens greatly impact the wellbeing of rural West African families. Herbivory by migratory or local livestock represents a significant source of crop loss. Live-fencing gardens with thorny hedges is a low-cost and sustainable strategy for reducing losses due to herbivory. However, guidance on the establishment of thorny hedges is inconsistent, poorly publicized, and often anecdotal. Therefore, this study evaluated the effects of three early pruning treatments on near-ground branch density of four thorny species: Vachellia nilotica, Senegalia laeta, Senegalia mellifera, and Prosopis juliflora. Physical measurements and photographic data indicated that after one growing season, V. …

Assessing The Impact Of A Constructed Wetland Biome On The Ecosystem Health Of Cedar Run, Thomas Vasilopoulos, Casey Lee

Senior Honors Projects, 2010-2019

A wetlands ecosystem is defined as “an area saturated by surface or groundwater at a frequency or duration sufficient to support...a prevalence of vegetation typically adapted for life in saturated soil conditions” (Batzer and Sharitz, 2007). Wetlands serve as biofilters and thus have been used to treat sewage and wastewater, as well as to restore the health of polluted water systems. Solly Walker and Lorinda Palin, owners of a certified natural and biodynamic farm called Avalon Acres located in Broadway, Virginia, constructed a wetland two years ago, using the stream, Cedar Run, that flows through their property. Pollution from agricultural …

A Green Oasis: What Makes Community Gardens Worth Saving? While Researchers Amass Evidence Of Benefits, Advocates Develop New Strategy To Prove Their Value., Joel Wolfram

Capstones

Green Valley Community Garden in Brownsville, Brooklyn, is one of about a dozen gardens on land owned by the New York City Department of Housing Preservation and Development that are being uprooted by plans to build affordable housing. The gardeners are fighting back to prevent the garden’s destruction, saying that the food-producing green space is a source of healthy eating in a community with high rates of health problems, like diabetes and obesity. Researchers are attempting to tease out the public health benefits of community gardens as one metric of their value, but the science is still catching up with …

Natural Burial: Being Green In Life, Now In Death Too, Brandon C. Shaik

Capstones

Nearly 80 million baby boomers are approaching the end of their lives. Being more environmentally conscious than previous generations, the environmentally minded individuals are increasingly choosing natural burial as the next progression of sustainability — reducing an individual impact even after death. A 2015 poll conducted by Harris Poll on behalf of the Funeral and Memorial Information Council found that 64 percent of adults over the age of 40 were interested in natural burial, up from 21 percent in 2010. Individuals who have chosen natural burial indicate the environmental benefit as a primary reason for their decision. There are currently …

Flight of the Freshwater Fish

The Hudson River provides for millions of people as a path for commercial and private transportation, a source of food and energy, and perhaps most importantly for many living in the tri-state area as a destination for recreation and relaxation. The most overlooked feature of the river is how the wildlife shows clear signs of a changing climate and rapid environmental response to the impacts of global warming on the river.

Entire populations of fish species in the lower Hudson have been forced to leave the river …

Getting Road Expansion On The Right Track: A Framework For Smart Infrastructure Planning In The Mekong, Andrew Balmford, Huafeng Chen, Ben Phalan, Mingcheng Wang, Christine S. O'Connell, Cath Tayleur, Jianchu Xu

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The current unprecedented expansion of infrastructure promises to enhance human wellbeing but risks causing substantial harm to natural ecosystems and the benefits they provide for people. A framework for systematically and proactively identifying the likely benefits and costs of such developments is badly needed. Here, we develop and test at the subregional scale a recently proposed global scheme for comparing the potential gains from new roads for food production with their likely impact on biodiversity and ecosystem services. Working in the Greater Mekong—an exceptionally biodiverse subregion undergoing rapid development—we combined maps of isolation from urban centres, yield gaps, and the …

Resource Assessment Report Western Rock Lobster Resource Of Western Australia, Simon De Lestang, Nick Caputi, Jason R. How

WA Marine Stewardship Council report series

The western rock lobster Panulirus cygnus (George) is taken by commercial and recreational fishers throughout its geographic range along the lower west coast of Western Australia. The main commercial fishery for P. cygnus is the West Coast Rock Lobster Managed Fishery (WCRLMF), which is Australia’s largest single-species fishery, currently worth about $400 million annually. Western rock lobster provides the basis for the economies of a number of coastal towns and also supports a recreational fishery.

Persistent Organic Chemicals In The Pacific Basin Countries: An Overview, Bommanna G. Loganathan

This two-year study investigated short-season winter cover crops to improve soil quality and growth of subsequent vegetable crops in an organic high tunnel production system. Five winter cover crop treatments including a nontreated control, Austrian winter peas (Pisum arvense), bell beans (Vicia faba), mustard (Brassica juncea cv. Kodiak), and Daikon radish (Raphanus sativus var. longipinnatus) were grown in a high tunnel in a randomized complete block design from mid-November to mid-March, mowed and incorporated into the soil, and followed by a succession of vegetable crops including tomato (Lycopersicon lycopersicum, cv. ‘Plum Dandy’) and broccoli (Brassica oleracea var. italica, cv. ‘Bay …

Modern Fair-Weather And Storm Sediment Transport Around Ship Island, Mississippi: Implications For Coastal Habitats And Restoration Efforts, Eve Rettew Eisemann

Master's Theses

The Mississippi – Alabama barrier island chain is experiencing accelerated sea level rise, decreased sediment supply, and frequent hurricane impacts. These three factors drive unprecedented rates of morphology change and ecosystem reduction. All islands in the chain have experienced land loss on the order of hectares per year since records began in the 1840s. In 1969, Hurricane Camille impacted as a Category 5, breaching Ship Island, and significantly reduced viable seagrass habitat. Hurricane Katrina impacted as a Category 3 in 2005, further widening Camille Cut. To better understand the sustainability of these important islands and the ecosystems they support, sediment …

From Access To Excess: Agribusiness, Federal Water Programs, And The Historical Roots Of The California Water Crisis, Tracy Marie Neblina

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this paper is to show the link between water use, land consolidation, agribusinesses, and the water crisis that California began to experience in 2011. In order to better understand the relationship between the growth of agribusiness in the state and the evolution of water policy, this paper explores the historical context of land policy, the growth of farming in the San Joaquin Valley, and the development of federally funded water projects in the Central Valley. Years of expanding farmland and use of surface and underground water with limited regulation played an important role in exacerbating California’s water …

Stationary Nonimaging Concentrators – A Comprehensive Study And Design Improvements, Srikanth Madala

UNLV Theses, Dissertations, Professional Papers, and Capstones

Most places on our planet receive an annual average radiation between 800-1000 W/m2. In the man-made world, this radiation is largely incident on stationary structures such as buildings, roads, monuments, bridges etc. Moreover, in the natural world also, there are large tracts of barren land which can be put to good use given their solar energy potential. The vision of the current research is to concentrate all this available solar energy to a more readily usable form. Therefore, stationary nonimaging solar concentrator technologies are sought after. This dissertation work is an exhaustive research on the nonimaging concentrating mechanisms with stationary …

Adjustment And Optimization Of The Cropping Systems Under Water Constraint, Pingli An, Wei Ren, Xiliin Liu, Mengmei Song, Xuemin Li

Plant and Soil Sciences Faculty Publications

The water constraint on agricultural production receives growing concern with the increasingly sharp contradiction between demand and supply of water resources. How to mitigate and adapt to potential water constraint is one of the key issues for ensuring food security and achieving sustainable agriculture in the context of climate change. It has been suggested that adjustment and optimization of cropping systems could be an effective measure to improve water management and ensure food security. However, a knowledge gap still exists in how to quantify potential water constraint and how to select appropriate cropping systems. Here, we proposed a concept of …

Predicting Post-Fire Change In West Virginia, Usa From Remotely-Sensed Data, Michael Strager P. Strager, Melissa Thomas-Van Gundy, Aaron E. Maxwell

Journal of Geospatial Applications in Natural Resources

Prescribed burning is used in West Virginia, USA to return the important disturbance process of fire to oak and oak-pine forests. Species composition and structure are often the main goals for re-establishing fire with less emphasis on fuel reduction or reducing catastrophic wildfire. In planning prescribed fires land managers could benefit from the ability to predict mortality to overstory trees. In this study, wildfires and prescribed fires in West Virginia were examined to determine if specific landscape and terrain characteristics were associated with patches of high/moderate post-fire change. Using the ensemble machine learning approach of Random Forest, we determined that …

Benchmark Levels For The Consumptive Water Footprint Of Crop Production For Different Environmental Conditions: A Case Study For Winter Wheat In China, La Zhuo, Mesfin Mekonnen, Arjen Y. Hoekstra

Daugherty Water for Food Global Institute: Faculty Publications

Meeting growing food demands while simultaneously shrinking the water footprint (WF) of agricultural production is one of the greatest societal challenges. Benchmarks for the WF of crop production can serve as a reference and be helpful in setting WF reduction targets. The consumptive WF of crops, the consumption of rainwater stored in the soil (green WF), and the consumption of irrigation water (blue WF) over the crop growing period varies spatially and temporally depending on environmental factors like climate and soil. The study explores which environmental factors should be distinguished when determining benchmark levels for the consumptive WF of crops. …
