A Landscape Approach To Late Prehistoric Settlement And Subsistence Patterns In The Mojave Sink, Tiffany Ann Thomas Dec 2011

A Landscape Approach To Late Prehistoric Settlement And Subsistence Patterns In The Mojave Sink, Tiffany Ann Thomas

UNLV Theses, Dissertations, Professional Papers, and Capstones

The environment of the Late Prehistoric period (1200 A.D. to Historic Contact) Mojave Sink was wetter than modern conditions. The settlement and subsistence patterns of the occupants of the region during this period were driven by the availability of water, subsistence resources, raw material sources, and tradition. These people utilized the regional landscape based upon the seasonal availability of these resources. Supplemental agricultural production has been proposed for the Mojave River Delta due to the more favorable environmental conditions of this period. If agriculture was being practiced it would have affected the regional land-use patterns. For this thesis I propose …


Knowledge And Perceptions Of Agriculture In Tennessee Through Fall Agritourism Experiences, Jessica Jarrell Poore Aug 2011

Knowledge And Perceptions Of Agriculture In Tennessee Through Fall Agritourism Experiences, Jessica Jarrell Poore

Masters Theses

The purpose of this study was to identify the key educational components of agritourism in Tennessee.

Additional data was gathered through an …


Extent, Characteristics And Downstream Effects Of Stream Enclosure In Southwestern Ontario, Katie L. Stammler Jun 2011

Extent, Characteristics And Downstream Effects Of Stream Enclosure In Southwestern Ontario, Katie L. Stammler

Electronic Thesis and Dissertation Repository

In a 16000 km2 area of southwestern Ontario, almost 15% of all streams have been enclosed (buried) largely for agricultural purposes. ArcGIS was used to characterize the natural features of catchments and to calculate enclosedness (proportion of stream network enclosed; x̅ = 16.5%, n = 10106). Catchments with the highest enclosedness received >990 mm of precipitation annually and had high drainage density (>1.9 km/km2), while catchments with the lowest enclosedness receivedannually, were characterized by clay and undrumlinized till plains and had relatively shallow water tables (m). These natural features influence where enclosure is likely to occur, …


Farmers Motivations To Practice Sustainable Agriculture, Kimberly A. Floeser Jun 2011

Farmers Motivations To Practice Sustainable Agriculture, Kimberly A. Floeser

Honors Theses

An increasing awareness of human and environmental health issues and the destruction of family farms and rural communities have caused a significant change in the way many farmers, consumers, and policy‐makers are thinking about and relating to food, the results of which can be seen largely in the growth of the organic and sustainable food industry. This paper attempts to examine and explain farmers’ attitudes towards sustainable agriculture, and their motivations to use sustainable methods of production. A survey was distributed to 533 farms that are members of the Northeast Organic Food Association of New York (NOFA‐NY). The data obtained …


Overcoming The Obstacles To Sustainability In Ghana, Ashley M. Scott Jan 2011

Overcoming The Obstacles To Sustainability In Ghana, Ashley M. Scott

CMC Senior Theses

For several decades following its independence from Great Britain, Ghana’s policies continued to promote over-extraction of natural resources to the detriment of its economy and rural communities. Agricultural and forestry policy has gradually evolved to foster more sustainable and equitable practices, as in building partnerships with the private sector to fund infrastructure improvements. Policy has recently recognized the dire need to adopt agricultural practices and means of forest resource extraction that are compatible with ecological stewardship. However, many shortcomings are still apparent. Large logging operations completely disregard forestry regulations with impunity, whereas rural sustenance extractors are severely punished in the …
