| Maize, the second most globally important staple crop after wheat, originated in Mexico, where it is typically grown as part of a set of associated crops and practices called the milpa system. This ancient mode of production is practiced today in ways that vary by cultural context and agro-environment. Milpas generate private economic value, in terms of food security, diet quality and livelihoods, for the two-million farm households who manage them. Furthermore, milpas generate public economic value by conserving agrobiodiversity, especially that of maize landraces, which have the potential to contribute unique traits needed by plant breeders for future crop improvement. In this way, milpas contribute to global food security in maize. However, the... |

| The regulatory approval of genetically modified crops in the field initially requires small, restricted experimental trials known as confined field trials. These small scale experiments provide researchers with important information on environmental interactions and agronomic performance of the crop in a safe and contained manner. To authorize confined field trials regulatory review is required, with formats for obtaining relevant information differing from country to country. In this paper, a Gap Analysis is used to identify informational gaps and potential for harmonization of confined field trial application processes in three East African countries - Tanzania, Kenya, and Uganda. The basic principle behind gap analysis is a comparison of the status quo... |

| Release of a genetically modified (GM) crop variety would lower prices of competing pesticides used on conventional varieties. This causes an increase in surplus for those farmers who adopt the GM variety, as well as for those who plant the conventional variety. A Cournot model was developed to determine the equilibrium quantities of conventional pesticides. A market with conventional wheat was compared to a market with both conventional and GM wheat varieties to identify price decreases of the conventional pesticide as a result of the GM trait introduction. |

| Development of genetically modified (GM) and specialty crops has had a great impact on the grain handling industry during recent years. Added costs associated with handling these crops have become an important issue for grain handlers. For this study, data were collected from a survey of elevators in the Upper Midwest. The information focused on segregation practices, time requirements, and costs. This study shows the different costs (grading and handling) associated with segregation practices at the grain-handler level. The results revealed that the cost of modifying systems to handle GM is of major importance. A stochastic simulation model of an engineering cost function is developed to analyze costs for segregation and testing using results from the... |

| Consumer attitudes towards genetically modified (GM) food are well documented but there has been much less focus on farmer attitudes to GM technology in agriculture. This paper reports findings from a study investigating farmers’ attitudes to GM crops in Scotland. Results from a Q methodology study reveal three discourses, one apparently pro-GM and demonstrating an expectation of benefits, the second representing a more uncertain position, wary of the potential risks of the technology but likely to be reluctant adopters, and the third describing a group who demonstrate a somewhat fatalistic attitude towards the issue of GM technology adoption and impact. The paper also reports findings from a postal survey conducted as part of the Q methodology study.... |
