Sustainability For Whom? Place-Makers Of Detroit, Dominica, Ecuador, And Mexico, Emma Gaalaas Mullaney
Sustainability For Whom? Place-Makers Of Detroit, Dominica, Ecuador, And Mexico, Emma Gaalaas Mullaney
Sponsored Events -- List
Drawing from more than a decade of work with farmers in rural and urban areas across the Americas, Professor Gaalaas Mullaney highlights some key findings about how small-scale farmers have a big influence on the conservation of cultural and ecological richness in their region. In each of these diverse places, innovative farmers work at the margins of dominant political and economic institutions with only occasional recognition of the value that they produce. What can these farmers teach us about how to cultivate place-based sustainability? How is sustainability related to social and economic justice?
A Comparative Analysis Of Feed And Environmental Factors On Broiler Growth In The United States, Alexandra Gulli
A Comparative Analysis Of Feed And Environmental Factors On Broiler Growth In The United States, Alexandra Gulli
Graduate Theses and Dissertations
Broiler production in the United States has become an important industry within the last half century. As the demand for poultry continues to increase and the concern of climate change also increases, it will become an important part of the industry to become more sustainable. This study uses a feed optimization model, a broiler growth model, and a life cycle assessment (LCA) to determine how feed ingredients and the barn environment can affect the broiler’s growth and production emissions. A multi-criteria ration optimization model is used to produce feeds based on carbon footprint and cost. A growth model is used …
Reconciling The Challenge Of Aphanic Species Within Marine Conservation, Kerri L. Bolow
Reconciling The Challenge Of Aphanic Species Within Marine Conservation, Kerri L. Bolow
HCNSO Student Capstones
Aphanic species are those within a taxonomic complex that may not be readily distinguishable from other sympatric species. The existence of these species is becoming apparent at an increasing rate through the use of technological tools like molecular genetic analyses. A lack of clarity on the definitions of terms used to describe similar species, how these species are identified, and how prevalent they are can confound identification, description, and management of these organisms. This review collects and defines the terms used to describe these hidden species and suggests the use of the term aphanic for situations where additional information (and …
Sustainability Assessment Of U.S. Beef Production Systems, Greg Thoma, Ben Putman, Marty Matlock, Jennie Popp, Leah English
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 …
Nitrogen Sustainability: Impediments To Action And Communication, Eric E. Jorgensen
Nitrogen Sustainability: Impediments To Action And Communication, Eric E. Jorgensen
Journal of Environmental Sustainability
“Sustainability” is widely used to imply the presence of explicit consideration of environmentally friendly needs and that high societal-value is placed on those needs. However, it is abundantly clear after 30 years that talking about sustainability and achieving it are two entirely different things. The core concept underlying sustainability is that current human practices and activities be conducted so as to not degrade prospects for future generations. With nitrogen, conflicts about sustainability in-theory and sustainability in-practice are close to the surface because of nitrogen’s central role in food production and economic activity. Measures of nitrogen inputs commonly range as high …
Technological Modernization And Its Impact On Agriculture, Fisheries And Fossil Fuel Utilization In The Asia Pacific Countries With Emphasis On Sustainability Perspective, Rajee Olaganathan, Kathleen Quigley

Modernization is a process that moves towards efficiency. This affects most of the fields such as agriculture, fisheries, forestry, urban planning, policy, fossil fuel usage, manufacturing, technology, economic growth etc. This process plays a major role in moving forward making things faster, better and basically more efficient. The effects of modernization on all these fields bring about the major changes to aspects such as social, economic and the environment. The level of operation has increased from a domestic level; small family scale business to large commercial levels. As the level of operation increased, the utilization of natural resources increased gradually …
