Genetiškai modifikuotų augalų paplitimo ir poveikio aplinkai analizė ir Lietuvos gyventojų požiūrio apžvalga / The analysis of genetically modified plants spread and environment impact and the analysis of lithuanian people attitude

Dževečkaitė, Neringa 08 September 2009 (has links)
Genetiškai modifikuoti augalai kuriami siekiant sukurti naujas veisles, t.y pagerinti augalų technologines ir maistines savybes. Genų inžinerijos metodais sukurta tūkstančiai naujų veislių. Tai augalai atsparūs herbicidams ir insekticidams. Nors pirmieji komerciniai GM pasėliai užauginti 1994 metais (pomidorai), 1996 metai laikomi metais, kuomet GM pasėliai pradėti auginti plačiu mastu (1,66 milijono hektarų). Nuo tada GM pasėlių auginimas augo labai staigiai ir 2005 metais tokie pasėliai užėmė 87,2 milijonus hektarų ploto. Didžiausią GM pasėlių plotą užima: soja, javai, medvilnė ir rapsai. Genetiškai modifikuoti augalai – produktas naujų technologijų. Tokie ugalai įgauna savybių kurios jiems iki tol nebuvo būdingos. GM maisto saugumas dar nėra įroditas. Tyrimai nebuvo ilgalaikiai ir pakankami. Šie augalai gali būti pavojingi tiek žmogaus sveikatai, tiek ir aplinkai. Siekiant užtikrinti, kad GM augalai ir GM produktai atitiktų nustatytas žmonių ir gyvūnų saugos bei aplinkos apsaugos reikalavimus, būtina atlikti rizikos aplinkai, žemės ūkiui, gyvūnų ir žmonių sveikatai įvertinimą ir vykdyti monitoringą. / Genetically modified plants (GM plants) are being engineered in order to develop different new species, i.e. enhancing technological and nutrient traits. There have been engineered thousands of new plants species, employed genetic engineering methods. The dominant plants are GM herbicide tolerant plants and GM insecticide tolerant plants. Although the first commercial GM crops were planted in 1994 (tomatoes), 1996 was the first year in which a significant area 1.66 mln.ha of crops were planted containing GM traits. Since then there has been a dramatic increase in plantings and by 2005, the glogal planted area reached almost 87,2 million hectares. Almost all of the global GM crop area derives from soybeans, corn, cotton and canola. Genetically modified plants are products of new technologies. Plants develop new characteristics which were not typical of them before. Safety of GM food has not been proved. The research wasn’t long-term and sufficient enough. This plants can be dangerous for human health and for environment. In order to ensure the requirement established for safe handling, use and control of the GM plants and GM products for human and animal health end environmental protection, it is necessary to perform risk assessment posed by GM plants and GM products to the environment, agriculture and human health and to organize constant monitoring.

DO EXPORTS AND GMO REGULATIONS DETERMINE ADOPTION RATE OF GM CROPS BY EXPORTING COUNTRIES

Meyu, Louria SUNTA ANAK 01 May 2020 (has links)
This thesis examines the role of exports and GMO regulations of the exporting country on the adoption of GM crops by its farmers. The analytic sample includes five major exporting countries including Argentina, Brazil, China, India, and Mexico. I focus only on the crop that is widely grown in each country. The crops are cotton, maize, and soybean. GMO regulations indices, which were constructed by Vigani et al, consists of four categories of different regulations related to import of GMO products. Relative impact of different aspects of GMO regulations on exports are assessed to get a better understanding of domestic production decisions of farmers in major exporting countries. The result for the approval process, risk assessment and international agreement suggested that, these regulations are not significant to influence the adoption rate of the GM crops. The exporting countries, especially the developing countries, usually reluctant to implement the GM regulations because of the high cost of completing the procedures.

Transparency in Federal Policy-Making: the Case of Biotechnology in Animals Intended for Human Consumption

Lee, Heather January 2013 (has links)
This research project examines the degree of transparency of the Canadian Federal Government’s decision-making processes and institutions with respect to the human consumption of animals produced through modern biotechnology (biotechnology-produced animals). It provides a timely study of the Federal Government’s decision-making process; as of January 2013 the government has yet to determine whether, and how, biotechnology-produced animals are to be approved for human consumption. Foods that contain genetically modified organisms (GMOs) are already commercially widely available in Canada. Research is well underway to see if biotechnology-produced animals may also be developed and introduced into the food system. Government decisions regarding the human consumption of biotechnology-produced animals have the potential to revolutionize food systems globally and nationally. This thesis offers an analysis of primary and secondary data focusing on the degree of federal transparency with respect to regulating GMO foods generally and, more specifically, the emerging policy issues around biotechnology-produced animals. This exploration sets the stage for the following investigation of barriers as well as opportunities to fostering federal transparency with respect to policy and regulatory decisions regarding GMO foods. Findings are directed towards members of the communities of interest who are interested in questions relating to the degree of federal transparency and government approaches to foods that contain material produced through modern biotechnology.

Democratizing agricultural planning in New Mexico : a participatory model

Jaramillo, Catherine 04 December 2013 (has links)
Rural areas of New Mexico still exhibit post-colonial political patterns. In terms of its agricultural profile, subsistence farming has only recently (in the past generation) begun to give way to highly specialized, big-business farming interests. Older Hispanic and Pueblo communities struggle to maintain their farming traditions in the face of external economic factors. Now, with the increasing use of genetically-modified seeds on major farm operations and the ongoing development of a transgenic chile seed, a heritage crop, these populations are grappling with intellectual property issues and ecological implications that technological manipulation of native seeds bring. Other growers across the state also have serious concerns about their ability to grow crops from non-genetically modified seeds, as consumers have shown a preference for organic, non-genetically modified foods. Using the guiding analytical tools of Latour and Callon's Actor Network Theory (ANT), I assess the dynamics of power and influence among all agricultural stakeholders to find how a network of disparate elements can achieve “compromise among materially diverse elements” (Rutland and Aylett 2008). This work outlines a framework based on deliberative democratic principles to begin a participatory process that builds upon the disconnected agricultural network of New Mexico. A deliberative process enfranchises previously neglected stakeholders to develop an agricultural policy that deals with genetically engineered crops in a way that reflects the values and goals of the public. / text

Genetiškai modifikuotų organizmų ir genetiškai modifikuotų produktų teisinio reguliavimo problemos / Law regulation problems of genetically modified organisms and genetically modified products

Liudvinavičiūtė, Eglė 08 September 2009 (has links)
Neatsiejama genetiškai modifikuotų organizmų (GMO) bei iš jų pagamintų produktų (GMP) teisinio reguliavimo dalis yra mokslas bei politika. –iame darbe analizuojamas GMO (GMP) teisinio reguliavimo raida ES ir Lietuvos Respublikoje. Nagrinėjamos tokios GMO ir GMP teisinio reguliavimo problemos, kaip etikos nuostatų suderinimas su žmogaus genų naudojimu kuriant maistui skirtus produktus; ES institucijų ir valstybių narių pozicijų išsikyrimas siekiant uždrausti apgalvotą GMO išleidimą į aplinką; visuomenės dalyvavimo priimant sprendimus dėl GMO (GMP) problematika ES ir Lietuvos Respublikoje – visuomenės „motyvuotos nuomonės“ instituto neefektyvumas. Taip pat analizuojamos ES teisės nuostatų dėl sankcijų nustatymo už GMO (GMP) reguliuojančių teisės aktų pažeidimus įgyvendinimo Lietuvos Respublikoje problemos t.y. nacionalinėje teisėje nenustačius atsakomybės pagrindiniams su GMO (GMP) veikla susijusiems juridiniams asmenims, praktiškai išlieka jų nebaudžiamumas; tai pat pažymėtina, kad teisės aktų, reglamentuojančių GMO ir GMP naudojimą, reikalavimų pažeidimai yra pakankamai skirtingo pobūdžio, o ATPK jie išvardinti viename straipsnyje, kartu numatyta gana didelis skiriamos baudos mažiausias dydis, - visa tai praktikoje sąlygoja nuobaudų neskyrimą bei neužtikrina Direktyvoje 2001/18/EB įtvirtintos sankcijos veiksmingumo, proporcingumo ir atgrasumo. Darbe nagrinėjamos tarptautinių sutarčių - Biologinės įvairovės ir Orhuso konvencijų - nuostatos dėl GMO bei jų įtaka ES ir Lietuvos... [toliau žr. visą tekstą] / Science and politics are part and parcel of law regulation of genetically modified organisms (GMO) and products (GMP) made from them. This work analyses development of law regulation of GMO (GMP) in ES and Lithuanian Republic. Such problems as ethical attitude towards usage of human genes in food production, distinction of ES isntitutions and member states according to their position, in purpose to forbid deliberate release of GMO into environment, problems of society involvment in taking decisions about GMO (GMP) in ES and Lithuanian Republic, inefficiency of public institute of "motivated opinion" (public comments) are disscussed in this work. Such topics as realisation of ES rules for definition of sanctions for breaking laws of GMO (GMP) usage in Lithuania Republic and rules of international contracts, such as Cartagena protocol on biosafety to the convention on biological diversity and Orhus convention, and their influence upon law regulation in ES and Lithuanian Republic are also disscussed here.

Labeling of genetically modified organisms and the producer's negative labeling decision under a voluntary labeling regime

Hu, Rongrong, 1970- January 2008 (has links)
During the past decade, there has been growing public attention and concern over consuming products containing or processed with genetically modified organisms (GMOs). Labeling of the food products derived from the use of GMOs has thereby been a contentious debate across the world. Currently, there are two systems with regard to labeling GMO-based products: mandatory versus voluntary. The purpose of this study was to survey the research on GMOs, its application in agriculture and the surrounding labeling issues. A theoretical model was developed to analyze non-GMO producers' labeling decisions under a voluntary labeling regime, aimed at providing a theoretical perspective for governments that are contemplating the adoption of a voluntary approach to regulate GMO food products. The analysis indicates that the size of labeling costs and consumers' preferences toward non-GMO products are critical factors that will impact on non-GMO producers' labeling decisions.
