Analysis for biotechnology innovations using Strategic Environmental Assessment (SEA) AgEcon
Lanacre, Nicholas A.; Gaskell, Joanne; Rosegrant, Mark W.; Falck-Zepeda, Jose Benjamin; Quemada, Hector; Halsey, Mark; Birner, Regina.
Meeting the food needs of the world’s growing population while reducing poverty and protecting the environment is a major global challenge. Genetically modified crops appear to provide a promising option to deal with this challenge. However there is a need to make strategic decisions on how to spend limited agricultural research funds in order to achieve a maximum impact with regard to finding sustainable solutions to end hunger and poverty. In international development institutions, there is growing interest in the potential use of Strategic Environmental Assessment (SEA) as part of a research based Environmental Management System (EMS) to promote mainstreaming of environmental considerations in policy development. SEA was developed as an approach to...

Anticipated Impacts of GMO Introduction on Production Pattern In Poland AgEcon
Maciejczak, Mariusz; Was, Adam.
The paper takes one significant element of the agriculture production – use of genetically modified organisms (GMO) – and considers it in relation to the production pattern in Polish farms. It asks if under the ceteris paribus conditions the use of GMO plants in Polish farms will have influence on the cropping structure. To answer this question only a scientific and theoretical assumption has been applied that GMO cultivation is permitted without restrictions in Poland. The approach combines both the very short experience of the new biotech based system of agricultural production and a modeling, which builds up and aggregates the impacts of individual farm responses under assumed situations.

Biotechnology: Can We Trade It? AgEcon
Bredahl, Maury E.; Kalaitzandonakes, Nicholas G..
The question in the title is divided into: (1) Can we trade the current generation of products from biotech or the technology itself? and (2) Can we trade the future generations of products of the technology? Controversy over the first generation of products has resulted in international trade being segmented into two markets: GMO-free and GMO. The first market is supported by voluntary labelling, making mandatory labelling largely unnecessary. While trade flows have been rearranged, markets have been little affected. We conclude that trade in the future generation will be dominated by capital and technology flows, with production for local markets dominating product trade flows.

COMPETITIVE ADVANTAGES OF POLISH ORGANIC SECTOR IN LIGHT OF CO-EXISTANCE BETWEEN GMO AND NON-GM PRODUCTS AgEcon
Maciejczak, Mariusz.
The perfect segregation of the different agricultural production types, namely conventional, organic or based on genetically modified organisms is not possible in practice. But the side by side functioning of this systems in agricultural production and further on of the products on the shelves requires suitable measures during cultivation, harvest, transport, storage, and processing to ensure co-existence. Consumers, food and feed industry, as well as wholesalers and retailers in European Union, including Polish ones demand a reasonable degree of choice between GMO and non-GMO derived products. Accordingly the ability to maintain different agricultural production and processing systems is a pre-requisite for providing a high degree of consumer choice. As...

Consumers' and Professionals' Responses to Situations Raising Ethical Questions AgEcon
Sirieix, Lucie; Gurviez, P.; Rohrig, C..
In this study we have attempted, in collaboration with an agrifood company, to compare and contrast the responses of consumers and professionals to the same set of situations raising ethical questions, in order to highlight the differences and the similarities of viewpoint between these two groups of stakeholders. In order to do this, we constructed multi-stakeholder scenarios comprising a description of the situation and the various possible approaches to managing the situation. We constructed two scenarios, dealing with the origin of the gelatin used in the company's products and the company's product information on livestock feed (GMO). This allowed us to: - study the extent of the professionals' ethical perceptions and the possible compromises between...

Consumers' Willingness to Pay for Genetically Modified Foods in Kenya AgEcon
Kimenju, Simon Chege; De Groote, Hugo.
A survey of 600 consumers was conducted in Nairobi to determine attitudes and willingness to pay (WTP) for GM maize meal. WTP was estimated using the double-bounded logit model. Overall, 38% are aware of GM crops. Most consumers believe in the technology's positive impacts, but are concerned about environmental and health risks. Majority (68%) would buy GM maize meal at the price of their favourite maize meal brand. The mean WTP for GM maize meal is KShs 58 for a 2kg packet, a premium of 13.7 % over mean average price of favourite brands. WTP is influenced more by subjective than socioeconomic characteristics.

Cost and benefits for the segregation of GM and non-GM compound feed AgEcon
Gryson, N.; Eeckhout, M.; Neijens, T..
Measures are being developed and implemented enabling the co-existence of conventional, genetically modified (GM) and organic cropping systems. In order to segregate GM from conventional crops in the entire supply chain, a food or feed company has to reorganise its production. This may involve for dedication of the production line to non-GM, or production can be organised on the same plant, using spatial or temporal segregation. In practice, only the latter method is used in the feed industry, as no investments in new machinery are necessary in the case. The segregation and identity preservation of GM and non-GM crops has to be well organised. An important tools used to proof the identity of the imported raw materials is the batch or product declaration...

Costs of Processing Genetically Modified Organisms: Analysis of the Rapeseed and Corn Industries AgEcon
Gawron, Jana-Christina; Theuvsen, Ludwig.
Die zunehmende Verbreitung gentechnisch veränderter Organismen (GVO) wirft die Frage nach möglichen wirtschaftlichen Konsequenzen auf. Die parallele Existenz von GVO- und GVO-freier Ware im Markt kann mit Kosten- und Nutzeneffekten verbunden sein und spielt somit aus betriebswirtschaftlicher Sicht eine wachsende Rolle für die Unternehmen der Ernährungswirtschaft. Vor diesem Hintergrund wurde im Herbst 2006 eine empirische Studie durchgeführt, um am Beispiel Raps und Mais die Strategien deutscher Lebensmittelverarbeiter im Umgang mit GVO sowie mögliche Zusatzkosten, die sich aus der zunehmenden Verbreitung von GVO ergeben können, zu ermitteln.

DEBUNKING THE MYTHS OF GM CROPS FOR AFRICA: THE CASE OF BT MAIZE IN KENYA AgEcon
Odhiambo, Benjamin; Bergvinson, David; Mugo, Stephen; De Groote, Hugo.
Empirical evidence from research on Bt maize in Kenya puts to rest most concerns raised against GMOs (not responding to farmers' needs, expensive, benefiting agro-business, risk of decreased biodiversity), but does indicate that contamination of local varieties is likely and buildup of insect resistance possible, requiring careful monitoring and evaluation.

Detection and quantification of Roundup Ready® soybean residues in sausage samples by conventional and real-time PCR Ciênc. Tecnol. Aliment.
Marcelino,Francismar Corrêa; Guimarães,Marta Fonseca Martins; De-Barros,Everaldo Gonçalves.
The increasing presence of products derived from genetically modified (GM) plants in human and animal diets has led to the development of detection methods to distinguish biotechnology-derived foods from conventional ones. The conventional and real-time PCR have been used, respectively, to detect and quantify GM residues in highly processed foods. DNA extraction is a critical step during the analysis process. Some factors such as DNA degradation, matrix effects, and the presence of PCR inhibitors imply that a detection or quantification limit, established for a given method, is restricted to a matrix used during validation and cannot be projected to any other matrix outside the scope of the method. In Brazil, sausage samples were the main class of...

Detection of genetically modified maize events in Brazilian maize-derived food products Ciênc. Tecnol. Aliment.
Branquinho,Maria Regina; Gomes,Déborah Márcia Vasconcelos; Ferreira,Renata Trotta Barroso; Lawson-Ferreira,Rafael; Cardarelli-Leite,Paola.
The Brazilian government has approved many transgenic maize lines for commercialization and has established a threshold of 1% for food labeling, which underscores need for monitoring programs. Thirty four samples including flours and different types of nacho chips were analyzed by conventional and real-time PCR in 2011 and 2012. The events MON810, Bt11, and TC1507 were detected in most of the samples, and NK603 was present only in the samples analyzed in 2012. The authorized lines GA21, T25, and the unauthorized Bt176 were not detected. All positive samples in the qualitative tests collected in 2011 showed a transgenic content higher than 1%, and none of them was correctly labeled. Regarding the samples collected in 2012, all positive samples were...

Ecological Risks of Novel Environmental Crop Technologies Using Phytoremediation as an Example AgEcon
Angle, J. Scott; Linacre, Nicholas A..
Phytoremediation is the use of living plants, known as hyperaccumulators which absorb unusually large amounts of metals in comparison to other plants. The use of classical plant breeding and new molecular techniques offers great potential to develop crops with the ability to clean up polluted sites. While these technologies have gained widespread attention, prior to commercial development, there are risks that must be considered – only a few of which have received even modest examination. Therefore, the focus of this working paper is to explore specific risks associated with phytoremediation and suggest ways in which these risks can be managed so that new, novel, and innovative plant technologies may be applied to provide low cost and efficient...

Extreme resistance to two Brazilian strains of Potato virus Y (PVY) in transgenic potato, cv. Achat, expressing the PVYº coat protein Horticultura Brasileira
Romano,Eduardo; Ferreira,Adriana T.; Dusi,André N.; Proite,Karina; Buso,Jose A.; Ávila,Antonio C.; Nishijima,Marta L.; Nascimento,Adriana S.; Bravo-Almonacid,Fernando; Mentaberry,Alejandro; Monte,Damares; Campos,Magnólia A.; Melo,Paulo Eduardo; Cattony,Monica K.; Torres,Antonio C..
The coat protein (CP) gene of the potato virus Y strain "o" (PVY O) was introduced into potato, cultivar Achat, via Agrobacterium tumefaciens-mediated transformation. Sixty three putative transgenic lines were challenged against the Brazilian strains PVY-OBR and PVY-NBR. An extremely resistant phenotype, against the two strains, was observed in one line, denominated 1P. No symptoms or positive ELISA results were observed in 16 challenged plants from this line. Another clone, named as 63P, showed a lower level of resistance. Southern blot analysis showed five copies of the CP gene in the extremely resistant line and at least three copies in the other resistant line. The stability of the integrated transgenes in the extreme resistant line was examined during...
