Climate Change Impacts On Rainfed Corn Production In Malawi, Kondwani Msowoya Jan 2013

Climate Change Impacts On Rainfed Corn Production In Malawi, Kondwani Msowoya

Electronic Theses and Dissertations

Agriculture is the mainstay of the economy in Malawi and accounts for 40% of the Gross Domestic Product (GDP) and 90% of the export revenues. Corn (maize) is the major cereal crop grown as staple food under rainfed conditions, covers over 92% of the total agricultural area, and contributes 54% of the caloric intake. Corn production is the principle occupation and major source of income for over 85% of the total population in Malawi. Issues of hunger and food insecurity for the entire nation are associated with corn scarcity and low production. Global warming is expected to cause climate change …


Anti-Nuclear Activism And The Past, Present And Future Of United States Nuclear Energy Policy, Isabel C. Zellweger Jun 2012

Anti-Nuclear Activism And The Past, Present And Future Of United States Nuclear Energy Policy, Isabel C. Zellweger

Honors Theses

Nuclear power has had a long and controversial history leading people to have many different views on the topic. Even though nuclear power does provide the nation with a significant portion of its electricity, many still fear its risks, especially after the events at Fukushima last spring. This thesis explores how public opinion, current events, and anti-nuclear activism have shaped nuclear power in America today. After reviewing the literature on nuclear energy in the United States, I discuss the past and current state of United States nuclear energy policy, and then describe changing American attitudes toward nuclear power over time. …


Uncertainty Estimation Of Extreme Precipitations Under Climate Change: A Non-Parametric Approach, Tarana A. Solaiman May 2011

Uncertainty Estimation Of Extreme Precipitations Under Climate Change: A Non-Parametric Approach, Tarana A. Solaiman

Electronic Thesis and Dissertation Repository

Assessment of climate change impacts on hydrology at watershed scale incorporates (a) downscaling of global scale climatic variables into local scale hydrologic variables and (b) assessment of future hydrologic extremes. Atmosphere-Ocean Global Climate Models (AOGCM) are designed to simulate time series of future climate responses accounting for human induced green house gas emissions. The present study addresses the following limitations of climate change impact research: (i) limited availability of observed historical information; (ii) limited research on the detection of changes in hydrologic extremes; and (iii) coarse spatio-temporal resolution of AOGCMs for use at regional or local scale. Downscaled output from …
