Use And Improvement Of Remote Sensing And Geospatial Technologies In Support Of Crop Area And Yield Estimations In The West African Sahel, Kaboro Samasse Jan 2021

Use And Improvement Of Remote Sensing And Geospatial Technologies In Support Of Crop Area And Yield Estimations In The West African Sahel, Kaboro Samasse

Electronic Theses and Dissertations

In arid and semi-arid West Africa, agricultural production and regional food security depend largely on small-scale subsistence farming and rainfed crops, both of which are vulnerable to climate variability and drought. Efforts made to improve crop monitoring and our ability to estimate crop production (areas planted and yield estimations by crop type) in the major agricultural zones of the region are critical paths for minimizing climate risks and to support food security planning. The main objective of this dissertation research was to contribute to these efforts using remote sensing technologies. In this regard, the first analysis documented the low reliability …


Urban Gardens And Nutrition In Sioux Falls, Sd, Austin Brynjulson Jan 2018

Urban Gardens And Nutrition In Sioux Falls, Sd, Austin Brynjulson

Electronic Theses and Dissertations

With the global population recently surpassing seven and a half billion, questions about feeding the population have emerged. In the past, increased demand for food was addressed through increasing intensification of land use and increasing the area of land under cultivation. Despite these efforts, food insecurity has increased for much of the population over this period, where, according to the USDA, in the U.S. 49.1 million people were food insecure in 2013. Food insecurity in this regard is the lack of access to sufficient, safe, and nutritious food at all times. While the complex global food system may be difficult …


The Role Of Ugandan Women In Rural Agriculture And Food Security, Karen Ann Mckenna Jan 2014

The Role Of Ugandan Women In Rural Agriculture And Food Security, Karen Ann Mckenna

Electronic Theses and Dissertations

Women engaged in small-scale rural agriculture in Iganga, Uganda for the purpose of household food security and/or income generation face a number of challenges to creating sustainable livelihoods. This analysis is presented in the form of a case study based on research conducted over the period of one year in Uganda between September 2012 and September 2013. Three conceptual orientations are used to guide the research, including sustainable livelihoods, gender and agricultural development, and food security. Pertinent economic, political, and social contexts are identified for each of these orientations. The author then identifies key challenges that women in Iganga face …


Energy In The Corn Belt: Is Maize Production Sustainable?, Matthew Bernau Jan 2013

Energy In The Corn Belt: Is Maize Production Sustainable?, Matthew Bernau

Electronic Theses and Dissertations

Technological and scientific innovation has transformed agricultural production. Corn production methods changed from a sustainable, nutrient recycling production system to one reliant on imported fossil energy inputs. Located in the Western Corn Belt, Union County, South Dakota was chosen as the study area. Changes in production methods are represented by four technological epochs: 1) The Draft Horse Epoch, 1890-1920; 2) The Tractor Epoch, 1920-1950; 3) The Fertilizer Epoch, 1950-1980; and 4) The Biotechnology and Precision Agriculture Epoch, 1980-2010. The energy budget method was used to measure the energy sustainability of corn production. The findings show that the volume of corn …


Predictors Of Food Insecurity In 3 Central Florida Communities, Tangela Towns Jan 2013

Predictors Of Food Insecurity In 3 Central Florida Communities, Tangela Towns

Electronic Theses and Dissertations

This study examined the association between different socio-demographic factors and food insecurity in the Central Florida Communities of Maitland, Winter Park, and Eatonville. Data from the Institute for Social and Behavioral Sciences at the University of Central Florida were utilized to analyze 3 main questions: In which community is food insecurity more prevalent? To what extent are food consumption, transportation, poverty, and unemployment associated with food insecurity? Does the association between food consumption, transportation, poverty, unemployment, and food insecurity remain when controlling for self-reported overall health, education, marital status, and race. The results revealed differences in predictors of food insecurities. …
