Failing Food Supply: Permaculture's Potential, John Faltin
Failing Food Supply: Permaculture's Potential, John Faltin
Department of Environmental Studies: Undergraduate Student Theses
Conventional agriculture is the currently leading production method to grow crops in the western hemisphere. Long-term sustainability of the system and all the components is secondary to producing high yields each growing season, which leads to issues such as erosion and reduced soil quality. Other agricultural production methods such as permaculture aim to build soil and improve quality every growing season. This experiment intends to look at the potential of permaculture to improve soil quality on small-scales at the end of each growing season. The parameters to gauge success are a larger concentration of macronutrients at the end of the …
Companion Planting: Effects Of Radishes On Squash Bugs, Daniel Dejong
Companion Planting: Effects Of Radishes On Squash Bugs, Daniel Dejong
Department of Environmental Studies: Undergraduate Student Theses
Throughout history, humans have continuously looked for easier and improved ways of growing our food. Over centuries of hybridizing crop varieties and more recently the invention and implementation of genetically modified (GM) seeds, we have created a food system that is dependent on chemical and seed companies to provide protection from environmental pests. The purpose of this thesis is not to discredit or dissuade someone from using GM seeds, but to take a look at some methods that could protect crops from environmental pests naturally, either for organic farmers or home gardeners. Specifically this review will examine methods of controlling …

How Livestock Production In Eastern Nebraska May Affect Nitrate Concentrations In Platte River, Yuzhe Luo
How Livestock Production In Eastern Nebraska May Affect Nitrate Concentrations In Platte River, Yuzhe Luo
Department of Environmental Studies: Undergraduate Student Theses
The Platte River is one of the largest rivers in Nebraska and serves as a valuable water source to cities along its watershed. Water is essential for both human life and social and economic development. The human body cannot survive without water for more than 3 days, and many industries require water to function. At a regional scale, the total amount of water is relatively constant, which means if some water sources were contaminated there will be less water available to use.

Daugherty Water for Food Global Institute: Faculty Publications
Target 6.4 of the recently adopted Sustainable Development Goals (SDGs) dealswith the reduction ofwater scarcity. To monitor progress towards this target, two indicators are used: Indicator 6.4.1 measuring water use efficiency and 6.4.2 measuring the level of water stress (WS). This paper aims to identify whether the currently proposed indicator 6.4.2 considers the different elements that need to be accounted for in a WS indicator.WS indicators compare water use with water availability.We identify seven essential elements: 1) both gross and net water abstraction (or withdrawal) provide important information to understand WS; 2) WS indicators need to incorporate environmental flow requirements …

Daugherty Water for Food Global Institute: Faculty Publications
Irrigation plays an important role in agriculture and the increase in the irrigated area and scarce water resources have encouraged the use of irrigation systems and management systems that increase the efficiency of water use. Thus, maximize water productivity has been one of the most important challenges in agriculture. The present study aimed to relate information on water productivity for two irrigation systems, drip and sprinkler systems, with the purpose of understanding the characteristics of these systems and contributing to the advancement of studies and research carried out in the area. Technological innovations aimed at reducing consumption and increasing water …
Loss Of Buffer Value Due To Aquifer Depletion: The Case Of High Plains Aquifer, Mani Rouhi Rad, Timothy Foster, Nicholas Brozovic
Loss Of Buffer Value Due To Aquifer Depletion: The Case Of High Plains Aquifer, Mani Rouhi Rad, Timothy Foster, Nicholas Brozovic
Daugherty Water for Food Global Institute: Faculty Publications
Existing literature in economics and engineering do not realistically capture the effects of aquifer depletion on loss of profits from agricultural production. While the former literature ignores the physical characteristics of aquifer and the relationship between aquifer levels and groundwater availability, the latter strand of literature does not consider farmers' decisionmaking as a result of aquifer depletion. Misspecification of these relationships and their effect on irrigation decisions can result in misunderstanding the consequences of aquifer depletion and may provide ineffective policies. This paper provides a framework to study the effects of aquifer depletion on the profit of agricultural production. We …

Mesonets: Mesoscale Weather And Climate Observations For The United States, Rezaul Mahmood, Ryan Boyles, Kevin Brinson, Christopher Fiebrich, Stuart Foster, Ken Hubbard, David Robinson, Jeff Andresen, Dan Leathers
High Plains Regional Climate Center: Personnel Publications
Mesoscale in situ meteorological observations are essential for better understanding and forecasting the weather and climate and to aid in decision-making by a myriad of stakeholder communities. They include, for example, state environmental and emergency management agencies, the commercial sector, media, agriculture, and the general public. Over the last three decades, a number of mesoscale weather and climate observation networks have become operational. These networks are known as mesonets. Most are operated by universities and receive different levels of funding. It is important to communicate the current status and critical roles the mesonets play. Most mesonets collect standard meteorological data …

Evaluating The Impacts Of Farmers’ Behaviors On A Hypothetical Agricultural Water Market Based On Double Auction, Erhu Du, Ximing Cai, Barbara Minsker
Evaluating The Impacts Of Farmers’ Behaviors On A Hypothetical Agricultural Water Market Based On Double Auction, Erhu Du, Ximing Cai, Barbara Minsker
Daugherty Water for Food Global Institute: Faculty Publications
Agricultural water markets are considered effective instruments to mitigate the impacts of water scarcity and to increase crop production. However, previous studies have limited understanding of how farmers’ behaviors affect the performance of water markets. This study develops an agent-based model to explicitly incorporate farmers’ behaviors, namely irrigation behavior (represented by farmers’ sensitivity to soil water deficit k) and bidding behavior (represented by farmers’ rent seeking l and learning rate b), in a hypothetical water market based on a double auction. The model is applied to the Guadalupe River Basin in Texas to simulate a hypothetical agricultural water market under …
Land Use As An Indicator Of Stream Habitat Quality In Salt Creek, Adam Brown
Land Use As An Indicator Of Stream Habitat Quality In Salt Creek, Adam Brown
Department of Environmental Studies: Undergraduate Student Theses
This study sought to quantify land use types in Lancaster County and identify which, if any, environmental parameters were significantly influencing fish and invertebrate distribution in the Salt Creek basin. Historical sampling data were obtained from the Nebraska Department of Environmental Quality. Watershed land cover maps were created and the percentages of urban/developed, forested, row crop, and grassland use were calculated. This data was combined with NDEQ water quality parameter, fish, and invertebrate sampling data to conduct nonmetric multidimensional scaling. This analysis did not provide significant conclusions about the driving force of fish and invertebrate distribution in this region because …

Population Structure Analysis Of Western Painted Turtles, Charrissa Zuerlein
Population Structure Analysis Of Western Painted Turtles, Charrissa Zuerlein
Department of Environmental Studies: Undergraduate Student Theses
Changes in the population structure, specifically the age, size and sex composition, of Western painted turtles can be studied to gain insight into the changes that will occur in closely related endangered species. As species with temperature-dependent sex determination (TSD), the sex ratios of new clutches are affected by climate, and this could cause problems for the species as climate changes occur. This study focuses on fluctuations in the population structure of a single population located near Cedar Point Biological Station in Ogallala, Nebraska. Each summer from 2005-2016 turtles were caught using floating basking traps and hoop nets. Results show …

Saving Money While Participating In Urban Agriculture, Jill Wieneke
Department of Environmental Studies: Undergraduate Student Theses
With more and more people pouring into urban areas, many have become unattached to where their food comes from and are disengaged with local food systems. Urban agriculture (UA) can bring people closer to healthy foods and be a potential savings. This will bring more resilience to a community and amend food insecurities Through this case study at the Hawley Hamlet Neighborhood Garden, urban gardeners can understand the capabilities of UA and the effects of food affordability into urban settings. This case study is an example of vegetable outputs and cost savings that can be obtained at a community garden …

Influence Of Internal Variability On Population Exposure To Hydroclimatic Changes, Justin S. Mankin, Daniel Viviroli, Mesfin Mekonnen, Arjen Y. Hoekstra, Radley M. Horton, Jason E. Smerdon, Noah S. Diffenbaugh
Daugherty Water for Food Global Institute: Faculty Publications
Future freshwater supply, human water demand, and people’s exposure to water stress are subject to multiple sources of uncertainty, including unknown future pathways of fossil fuel and water consumption, and ‘irreducible’ uncertainty arising from internal climate system variability. Such internal variability can conceal forced hydroclimatic changes on multi-decadal timescales and near-continental spatial-scales. Using three projections of population growth, a large ensemble from a single Earth system model, and assuming stationary per capita water consumption, we quantify the likelihoods of future population exposure to increased hydroclimatic deficits, which we define as the average duration and magnitude by which evapotranspiration exceeds precipitation …

Effects Of Initial Aquifer Conditions On Economic Benefits From Groundwater Conservation, T. Foster, N. Brozovic, A. P. Butler
Effects Of Initial Aquifer Conditions On Economic Benefits From Groundwater Conservation, T. Foster, N. Brozovic, A. P. Butler
Daugherty Water for Food Global Institute: Faculty Publications
Worldwide, there is growing recognition of the need to reduce agricultural groundwater use in response to rapid rates of aquifer depletion. To date, however, few studies have evaluated how benefits of conservation vary along an aquifer’s depletion pathway. To address this question, we develop an integrated modeling framework that couples an agro-economic model of farmers’ field-level irrigation decisionmaking with a borehole-scale groundwater flow model. Unique to this framework is the explicit consideration of the dynamic reductions in well yields that occur as an aquifer is depleted, and how these changes in intraseasonal groundwater supply affect farmers’ ability to manage production …

The Irreversible Momentum Of Clean Energy, Barack Obama
US Department of Energy Publications
The release of carbon dioxide (CO2) and other greenhouse gases (GHGs) due to human activity is increasing global average surface air temperatures, disrupting weather patterns, and acidifying the ocean. Left unchecked, the continued growth of GHG emissions could cause global average temperatures to increase by another 4°C or more by 2100 and by 1.5 to 2 times as much in many midcontinent and far northern locations. Although our understanding of the impacts of climate change is increasingly and disturbingly clear, there is still debate about the proper course for U.S. policy—a debate that is very much on display …

Compensatory Response Of Fathead Minnow Larvae Following A Pulsed In-Situ Exposure To A Seasonal Agricultural Runoff Event, Jonathan M. Ali, John Sangster, Daniel D. Snow, Shannon L. Bartelt-Hunt, Alan S. Kolok
Nebraska Water Center: Faculty Publications
Agriculturally-dominated waterways such as those found throughout the Midwestern United States often experience seasonal pulses of agrichemical contaminants which pose a potential hazard to aquatic organisms at varying life stages. The objective of this study was to characterize the developmental plasticity of fathead minnow larvae in a natural environment subject to a seasonal episodic perturbation in the form of a complex mixture of agricultural stressors. Fathead minnow larvae were maintained at the Elkhorn River Research Station for a 28-d in situ exposure to an agrichemical pulse event.Minnow larvae were sampled after 14 and 28 days to characterize developmental plasticity through …
