Genetically Modified Organisms As A Potential Solution For Decreasing Hunger In Developing Nations: An Ethical Paradox, Rachel Sherman

Independent Study Project (ISP) Collection

I first became aware of and interested in genetically modified organisms (GMOs) in the “Politics of Food in America” course I took spring semester of 2012, my junior year at the University of Texas at Austin. I was intrigued by the fact that such a concept was so unfamiliar to the public, yet genetically engineered products were in our everyday foods. Though I received a basic introduction to GMOs through my course, I was curious to learn more about the regulatory practices of GM crops and the political relationships sustained by GM firms and government agencies in the United States. …

Confronting Agrarian Crisis And Deconstructing Farmer Debt: The Story Of Sulthanpur Village, Andhra Pradesh, Erica Dejong

Independent Study Project (ISP) Collection

In a climate of globalized politics and neoliberal economics, it can be difficult to isolate the impacts of agricultural and economic policy on the lives of the rural poor in India. Hidden behind a veil of economic growth, pro urban, and pro industry governments, the stories of small and marginal farmers have been overlooked in the name of different development priorities. This study endeavors to put the agrarian poor back into the scholarship spotlight by deconstructing livelihood crises and farmer debt in Sulthanpur Village, Andhra Pradesh. This effort is important because although Andhra Pradesh has the highest rate of farmer …

Coarse Woody Debris In A Tropical Rainforest In North Queensland, Australia: Relationships With Stand Structure And Disturbance, Nadine Rea Apr 2012

Coarse Woody Debris In A Tropical Rainforest In North Queensland, Australia: Relationships With Stand Structure And Disturbance, Nadine Rea

Independent Study Project (ISP) Collection

Coarse woody debris (CWD) refers to the woody material on the forest floor, including fallen stems, large branches, coarse roots, wood pieces, and standing dead trees (snags) (Harmon et al. 1986). CWD is an essential but often overlooked aspect of ecosystems. It plays many key ecosystem roles and is instrumental in overall ecosystem functionality. While a piece of CWD decomposes, it provides key habitat for many different species, minimizes soil erosion, affects soil development, stores nutrients and water, and influences the global carbon cycle (Harmon and Hua 1991). In some forests, CWD can exist on the forest floor for hundreds …
