Gis For The Bartlett Hills Association: Increasing Knowledge To Enhance Land Management Practices, Stephanie R. Sattler Dec 2014

Gis For The Bartlett Hills Association: Increasing Knowledge To Enhance Land Management Practices, Stephanie R. Sattler

MS GIS Program Major Individual Projects

The natural world has many unique areas and when there is no management conducted on these areas, they become lost to time. The 800-acre property owned by the Bartlett Hills Association (BHA) in western Iowa is no different. The loess hills are deposits from glaciers 12,000 to 30,000 years ago, and over the last several decades there has been no management of these unique hills on the property. The BHA has established management objectives that will bring its forest back to a sustainable forest and its members want to use GIS to enhance their knowledge. There are currently ...


Beyond Sustainability: A New Conceptual Model, Molly Kerby, Gayle Mallinger Oct 2014

Beyond Sustainability: A New Conceptual Model, Molly Kerby, Gayle Mallinger

Faculty Publications

Over the last few decades, the notion of sustainability has become an interdisciplinary buzz word. Sustainability has been an integrative concept that includes three constructs or pillars: a) social; b) economic; and c) ecological. Until recently, theoretical approaches based on the three pillars approach have operated in silos rather than exploring the interconnectedness of the constructs. Few models have moved beyond the idea that logical relations exist among the constructs (social, economic, and ecological) to consider factors external to communities, nor have they examined the internal socio-economic factors that influence positive outcomes. While this conceptualization has raised awareness about the ...


Information And Entropy Theory For The Sustainability Of Coupled Human And Natural Systems, Audrey L. Mayer, Richard P. Donovan, Christopher W. Pawlowski Sep 2014

Information And Entropy Theory For The Sustainability Of Coupled Human And Natural Systems, Audrey L. Mayer, Richard P. Donovan, Christopher W. Pawlowski

College of Forest Resources and Environmental Science Publications

For coupled human and natural systems (CHANS), sustainability can be defined operationally as a feasible, desirable set of flows (material, currency, information, energy, individuals, etc.) that can be maintained despite internal changes and changes in the environment. Sustainable development can be defined as the process by which CHANS can be moved toward sustainability. Specific indicators that give insight into the structure and behavior of feedbacks in CHANS are of particular interest because they would aid in the sustainable management of these systems through an understanding of the structures that govern system behavior. However, the use of specific feedbacks as monitoring ...


Potential And Technological Advancement Of Biofuels, Rajee Olaganathan, Fabian Ko Qui Shen, Lim Jun Shen Aug 2014

Potential And Technological Advancement Of Biofuels, Rajee Olaganathan, Fabian Ko Qui Shen, Lim Jun Shen

Publications

This scientific paper examines the feasibility of biofuels as a solution to the world‟s energy crisis. It studies the development of the four different generations of biofuel that have been discerned over the years, determining the pros and cons of each. The paper further investigates the issues concerning each generation, and determines how their successors have solved and improved on those problems. In order to give the reader an unbiased perspective, the paper studies both general advantages and disadvantages that encompasses social, economic and environmental impacts. Research and development on the first two generations of biofuels have matured, and ...


Biodynamic Agriculture: A Valuable Alternative To The Industrial Farming System, Eden K. Olsen May 2014

Biodynamic Agriculture: A Valuable Alternative To The Industrial Farming System, Eden K. Olsen

Scripps Senior Theses

Since the Scientific and Industrial revolutions, advancing technologies and cutting-edge science have enabled our society to continually promote a growing global economy. Industrial growth has increasingly become a top priority for most governments, notably in the agricultural realm. The advances towards agricultural industrialization began in the 17th century and escalated during the Green Revolution, which examined the possibility of using synthetic fertilizers and mechanization in farming to decrease labor and improve yields. Although seen as economically beneficial, the shift from an agrarian lifestyle to industrial farming has created an ecological, economic, and ideological crisis to our modern world. This ...

Changes in land use, land cover, and land management present some of the greatest potential global environmental challenges of the 21st century. Urbanization, one of the principal drivers of these transformations, is commonly thought to be generating land changes that are increasingly similar. An implication of this multiscale homogenization hypothesis is that the ecosystem structure and function and human behaviors associated with urbanization should be more similar in certain kinds of urbanized locations across biogeophysical gradients than across urbanization gradients in places with similar biogeophysical characteristics. This paper introduces an analytical framework for testing this hypothesis, and applies the framework ...


Integral Agriculture: Taking Seriously The Mindset Of The Farmer, The Interiority Of The Beings On The Farm, And A Metaphysics That Connects Them, Travis E. B. Cox Jan 2014

Integral Agriculture: Taking Seriously The Mindset Of The Farmer, The Interiority Of The Beings On The Farm, And A Metaphysics That Connects Them, Travis E. B. Cox

Graduate Theses and Dissertations

With the steady increase in the market share of organic food over the last 30 years, some farmers have switched from "conventional" to "sustainable" agricultural practices in order to capitalize on those new markets. Are the practices the only things that need to change?

Building off of Warwick Fox's conception of "transpersonal ecology," transpersonal agroecology (TPAE) is the name given to a proposed alternative mindset of the farmer derived from various alternative agricultural theorists of the last 100 years. These writers oppose the scientism and economism that typify industrial agriculture, subscribe to the notion that experiences of "identification" between ...
