A Life Cycle Analysis Of Land Use In Us Pork Production, Greg Thoma, Marty Matlock, Ben Putman, Jasmina Burek

Food Systems

The goal of this study was to analyze land use in the production of US pork using Life Cycle Assessment (LCA). LCA is a comprehensive methodology for quantitatively analyzing potential environmental impacts associated with complex systems. Identification of processes contributing to high environmental impacts often highlights opportunities for gains in efficiency, which can increase the profitability and sustainability of US pork. The environmental impact category analyzed in this assessment was land use. After reviewing existing information regarding land use in agriculture and livestock production, analysis for US pork production was performed at two scales: cradle-to-grave and cradle-to-farm gate. The cradle-to-grave …

Quantifying The Adaptive Cycle, David G. Angeler, Craig R. Allen, Ahjond S. Garmestani, Lance H. Gunderson, Olle Hjerne, Monika Winder

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

The adaptive cycle was proposed as a conceptual model to portray patterns of change in complex systems. Despite the model having potential for elucidating change across systems, it has been used mainly as a metaphor, describing system dynamics qualitatively. We use a quantitative approach for testing premises (reorganisation, conservatism, adaptation) in the adaptive cycle, using Baltic Sea phytoplankton communities as an example of such complex system dynamics. Phytoplankton organizes in recurring spring and summer blooms, a well-established paradigm in planktology and succession theory, with characteristic temporal trajectories during blooms that may be consistent with adaptive cycle phases. We used long-term …

Wetland Inundation Mapping And Wetland Restoration Planning: A Case Study Of Playa Wetlands, Nebraska, Yue Gu

Community and Regional Planning Program: Theses

There has been a variety of wetland monitoring projects implemented in playa wetlands in Nebraska over the last decades. But there is still a lack of continuous wetland monitoring on long-term and large-area dimension. Because inundation condition is one of the critical parameters to describe wetland hydrologic performance, this study aims to assess the inundation alteration in playa wetlands in Nebraska and evaluate the performance of wetland conservation and restoration practices. This study uses the Landsat data to create playa wetland inundation condition maps and analyze the variation trend of inundated playa wetlands over the past 30 years. The results …

Macrobenthic Communities In The Northern Gulf Of Mexico Hypoxic Zone: Testing The Pearson-Rosenberg Model, Shivakumar Shivarudrappa

Dissertations

The Pearson and Rosenberg (P-R) conceptual model of macrobenthic succession was used to assess the impact of hypoxia (dissolved oxygen [DO] ≤ 2 mg/L) on the macrobenthic community on the continental shelf of northern Gulf of Mexico for the first time. The model uses a stress-response relationship between environmental parameters and the macrobenthic community to determine the ecological condition of the benthic habitat. The ecological significance of dissolved oxygen in a benthic habitat is well understood. In addition, the annual recurrence of bottom-water hypoxia on the Louisiana/Texas shelf during summer months is well documented.

The P-R model illustrates the decreasing …

Using Electrical Resistivity Imaging To Characterize Karst Hazards In Southeastern Minnesota Agricultural Settings, Toby Dogwiler, Blake Lea

Sinkhole Conference 2015

Much of the Driftless Area of southeastern Minnesota is underlain by karstified carbonate bedrock. Land use in this karst terrain is dominated by agriculture, including row crop and dairy operations. The karst in this region is often mantled with up to 15 m of soil and unconsolidated sediments. As a result, underlying karst hazards such as incipient sinkholes are often hidden until they are suddenly revealed by the collapse of subsurface voids. Regionally, the economics of the dairy industry is causing a trend toward the consolidation and expansion of existing operations. As concentrated animal feeding operations (CAFO) or feedlots expand, …

Using Future Benefits To Set Conservation Priorities For Wetlands, Samuel B. Merrill

Journal of Ocean and Coastal Economics

In an era of rising sea levels, costal land managers including land trust representatives, municipal planners, and others contributing to decisions about whether to develop or protect coastal parcels do not have viable means of evaluating future values on wetlands that will be created when sea levels rise. This project develops and tests a software modeling approach to help address this issue, in combination with a novel, expert-opinion driven benefit-cost framework. The beta test used three parcels in Scarborough, Maine: Hampton Circle, Maine Audubon, and Pine Point. It used a group of experts to 1) allocate initial values to these …

Economic Valuation Of Marine And Coastal Ecosystems: Is It Currently Fit For Purpose?, Nick Hanley, Stephen Hynes, David Patterson, Niels Jobstvogt

Journal of Ocean and Coastal Economics

In this paper, we consider whether the current “state of the art” of environmental valuation is suitable for producing policy-relevant estimates of the benefits or costs of changes in marine and coastal ecosystems. We review recent changes in European legislation which has meant an increasing demand for economic valuation from the policy and regulatory community. The next section considers, at a more conceptual level, whether the economic “toolbox” and scientific evidence is up to the task of meeting the demand for more evidence-based policy. Finally, three case studies are used to explore the nature of the valuation task and review …

Patagonia Con Poder: El Éxito De La Oposición Frente El Proyecto Hidroaysén, Nathaniel Korn

Independent Study Project (ISP) Collection

This investigation analyzes the movement in opposition to the HidroAysén project in Southern Chile that is often referred to as and uses the slogan “Patagonia Sin Represas” (Patagonia Without Dams). The investigation is framed through collective action theory, the study of what incentives and other factors create the conditions for mobilization and group action. In the context of social movements it is usually argued that there needs to be a better cost-benefit scenario for each actor to be involved than there is to not be involved in the movement. Immediately following return of democracy to Chile in the 1990’s social …

Water Quality In The Río Pastaza Watershed A Comparative Study Of Ríos Topo, Zuñag, And Pastaza And The Impact Of The Topo Hydroelectric Project Using Macroinvertebrates As Bioindicators, Jesse Vega-Perkins

Independent Study Project (ISP) Collection

Ríos Zuñag, Pastaza, and Topo flow through one of the rainiest and water-rich places in Ecuador. Río Zuñag is a relatively small, pristine montane river and Río Pastaza is a relatively large, contaminated river that receives the untreated wastewater of many communities. Río Topo’s unique watershed and gradient allow it to be home to many plants that have adapted to its unique environment, including the hyperendemic liverwort Myriocolea irrorata. However, in recent years, all of the water of Río Topo has been sold by the state of Ecuador to be developed for hydroelectric projects (HEP). The first of these …

No time to waste: Crowdsourcing global wastewater treatment data

Worldwide, over 80 percent of wastewater is discharged into water bodies without undergoing treatment, severely impairing human well-being and ecosystem vitality along the way. National performance on wastewater treatment is difficult to quantify and is poorly understood due to a lack of common definitions, poor data collection standards, and limited historical data. To address this, the Yale Environmental Performance Index (EPI), a research group that produces a biennial ranking of country-level environmental performance, developed a first-of-its kind national wastewater treatment indicator.[1]

The indicator assesses wastewater treatment performance for 183 countries, …

Groundwater Chemistry Of The Weaber Plain (Goomig Farmlands): Baseline Results 2010–13, Adam Lillicrap, Richard J. George Dr, Arjen Ryder, D L. Bennett

Resource management technical reports

The Ord River Irrigation Area (ORIA) is located in the north-east of the Kimberley region of Western Australia, near the town of Kununurra. The irrigation area was established in 1963 and over time developed to the current extent of 14 000 hectares (ha). The Weaber Plain (Goomig Farmlands) area is located north-north-east of the existing irrigation area, 30km from Kununurra, and has been identified as being suitable for irrigated agriculture for many decades. However, it was not until 2009, with state government support, that the 7400ha project commenced, with construction starting in 2010. State and Australian government environmental approvals required …
