Az élelmezés-, energia- és környezetbiztonság összefüggései AgEcon
Popp, Jozsef; Potori, Norbert.
A 2006/2007. gazdasági évtől a legtöbb mezőgazdasági termék ára gyors emelkedésnek indult és rekordokat döntött. A FAO élelmiszerár-indexe 2006 januárja és 2008 januárja között több mint 60 százalékkal emelkedett. Árkilengések persze korábban is előfordultak, de a legutóbbi ársokkot azonban számos tényező együttesen idézte elő. Ezek felsorolásánál első helyen említhető a világ gabona- és olajosmagkészleteinek megcsappanása: a Föld élelmiszermérlege évtizedek óta nem mutatott ilyen szűkös tartalékokat. Ehhez egyértelműen hozzájárult a rövidlátó gazdaságpolitika is. Ugyanakkor a média hajlamos az élelmiszerárak ugrásszerű növekedését inkább a feltörekvő gazdaságok (pl. Kína és India) élelmiszer-fogyasztási szerkezete átalakulásának és a bioüzemanyag-gyártás...

Crop Choice, Non-Target Pest Levels, Yield Loss and Their Effect on Insecticide Use in South Dakota AgEcon
McDonald, Tia Michelle; Keating, Ariel Ruth; Fausti, Scott W.; Li, Jing; Lundgren, Jonathan G..
Agriculturally, South Dakota is a unique state possessing the highest rate of adoption for genetically modified crop varieties. In 2009 ninety-six percent of corn acres planted in South Dakota were genetically modified compared with eighty-five percent nationally (Economic Research Service). Additionally, South Dakota has seen a dramatic increase in the number of acres treated with insecticide over the past 20 years. These two situations taken together seem to be counterintuitive. Some genetically modified varieties, such as Bt corn, are equipped with genetic defenses so that they can protect the plant from target pests. Intuitively, one would expect to see a decrease in insecticide use as adoption of genetically modified varieties increase. Recent...

Governing the Co-existence of GM Crops: Ex-Ante Regulation and Ex-Post Liability under Uncertainty and Irreversibility AgEcon
Beckmann, Volker; Soregaroli, Claudio; Wesseler, Justus.
The future institutional environment for the co-existence of genetically modified (GM) crops, conventional crops and organic crops in Europe combines measures of ex-ante regulation and ex-post liability rules. Against this background we ask the following two questions: How does ex-ante regulation and ex-post liability under irreversibility and uncertainty affect the adoption of GM crops? What are the implications for regional agglomeration of GM and non-GM crops? Ex-ante regulations and ex-post liabilities for using GM crops will induce additional costs. These costs are modelled in a classical way. The model is advanced by including irreversibility and uncertainty and taking into account transaction costs of negotiating possible solutions with neighbouring...

Grower Response to Contracts and Risk in Genetically Modified (GM) Crops AgEcon
Wilson, William W.; Dahl, Bruce L.; Maxwell, Brett J..
Contract strategies can resolve some of the challenges that exist for property rights conformance of genetically modified (GM) crops. The purpose of this research is to determine how contract terms impact adoption decisions related to GM grain production and marketing. A simulation model was developed for prospective GM introduction in hard red spring (HRS) wheat, and distributions of net returns for growers were analyzed using stochastic dominance and stochastic efficiency. Results illustrate that contracts can be designed to induce desired behavior. Technology fees, probabilities of detection, and the level of non-GM premiums were the most notable factors influencing adoption decisions. In addition, point-of-delivery pricing and premiums for non-GM...

MEDIA COVERAGE OF AGROBIOTECHNOLOGY: DID THE BUTTERFLY HAVE AN EFFECT? AgEcon
Marks, Leonie A.; Kalaitzandonakes, Nicholas G.; Allison, Kevin; Zakharova, Ludmila.
This study examines media coverage of genetically modified (GM) crops in a risk communication framework. Content analysis is employed to investigate how specific environmental, food safety, and landmark events, such as the monarch butterfly and Pusztai controversies, and the cloning of Dolly-the-sheep, were reported by the media. Media coverage is from United Kingdom and United States newspapers over the period 1990 through 2001. On balance, findings show that the UK press has been more negative than the U.S. press in its coverage of GM crops. In addition, environmental and food safety events had a significant impact on the level and cycle of GM crop coverage.

STUDY OF GENE FLOW FROM GM COTTON (Gossypium hirsutum) VARIETIES IN "EL ESPINAL" (TOLIMA, COLOMBIA) Acta biol.Colomb.
RACHE CARDENAL,LEIDY YANIRA; MORA-OBERLAENDER,JULIAN; CHAPARRO-GIRALDO,ALEJANDRO.
In 2009, 4088 hectares of genetically modified (GM) cotton were planted in Tolima (Colombia), however there is some uncertainty about containment measures needed to prevent the flow of pollen and seed from regulated GM fields into adjacent fields. In this study, the gene flow from GM cotton varieties to conventional or feral cotton plants via seed and pollen was evaluated. ImmunostripTM, PCR and ELISA assays were used to detect gene flow. Fifty six refuges, 27 fields with conventional cotton and four feral individuals of the enterprise "Remolinos Inc." located in El Espinal (Tolima) were analyzed in the first half of 2010. The results indicated seed mediated gene flow in 45 refuges (80.4 %) and 26 fields with conventional cotton (96 %), besides pollen...

The Cost of Coexistence between Bt Maize and Open Pollinated Maize Varieties in Lowland Coastal Kenya AgEcon
Tumusiime, Emmanuel; De Groote, Hugo; Vitale, Jeffrey D.; Adam, Brian D..
Kenya is currently in the process of introducing genetically modified maize (Bt maize). A major concern is that the Bt gene might cross into local varieties through cross pollination. Current regulatory strategies to ensure coexistence of the two cropping systems at the farm level rely on spatial isolation measures-separation distances and/or buffer zones. However, the interaction of practical measures and costs of spatial isolation with the farmer’s economic incentive to plant a Bt maize crop have not been studied in Kenya. The purpose of this study was to analyze the technical and economic feasibility of the implementation of spatial coexistence measures. Using spatial geo-referenced data from the actual agricultural landscape in lowland coastal Kenya,...
