Economic and Ecosystem Impacts of GM Maize in South Africa
… basis for direct human consumption using genetically modified (GM) cultivars. Using a combined economic and environmental approach, we estimate the total welfare benefits attributable to GM white maize in South Africa for 2001-2018 are $694.7 million. Food security benefits attributable to …

Valuing the Environmental Benefits from GM Products Using an Experimental Procedure: Lessons From the United States and the Philippines
… environmental benefits from two pre-production genetically modified (GM) products, MVR tomatoes and Bt eggplant. The procedure explicitly tells subjects the GM nature of the products, and frames the value as an actual donation to the scientific organization pursuing the product research. The …

Evolution of Bacillus thuringiensis Maize Yields in South Africa
<p>The economic and environmental benefits of genetically modified (GM) maize in South Africa have been well documented in previous literature. However, concerns about the longevity of these benefits, have been raised following reports of Busseola fusca developing resistance to Bacillus …

The effect of GM label variation on perceptions of genetically modified foods
… which are suggested to affect perceptions of genetically modified (GM) foods. It first tests the extent to which the components of the Theory of Planned Behaviour and perceived `outrage' are able to predict intentions towards buying GM foods using linear regression. It then focuses on how GM …

Risk, social trust and knowledge: public perceptions of gene technology in Britain
… case, gene technology, with special reference to genetically modified (GM) food, and one particular society, modern Britain. I am concerned firstly with the structure and stability of people’s perceptions of risks and, secondly, with some of the factors that underlie these perceptions. After a …

The "Silent Scream" of "Pathetic Seeds": exploring a feminist ethics of care as a means to broaden the scope of current GM crop risk assessment practices in South Africa
The risk assessment of genetically modified (GM) crops is assumed to be a benign regulatory tool, due to its perceived objectivity and freedom from the morals and values that pervade society. Yet, against the backdrop of growing environmental pressures, social tensions and political instability, …

Addressing Genetic Pollution from Pollen Drift on a Heterogeneous Landscape
<p>Genetically modified (GM) crops are crops in which single or multiple genes have been introduced artificially in order to obtain certain characteristics that are difficult to obtain through conventional breeding. Even though farmers have the right to freely choose what types of crops to grow, …

Biological Confinement of Zebrafish Using RNAi
… to alleviate the demand from the food industry, genetically modified (GM) fish were developed possessing traits such as larger mass, faster growth, and increased resistance to disease. However, the greater fitness advantage of GM fish presents potential risks for wild type populations in the …

Feral oilseed rape populations within a scottish landscape : Implications for GM coexistence and environmental risk assessment
… received global attention as a means by which genetically modified (GM) traits may persist in the environment. There are still major uncertainties, however, over the long term environmental and economic consequences of its persistence and invasiveness, particularly in relation to GM coexistence …
