Moreover, livestock production in many Southern countries has often been at the direct expense of poorer people's dominant personality traits. For further information about Cargill, see, Kneen, B. Poorer people who do not have cars are left to buy food at corner shops, convenience stores or independent small supermarkets where prices are on average 23 per cent higher than those in large supermarket chains and discount stores -- and where food may be even less fresh than in out-of-town stores. These points are not a consensus statement of the workshop; rather they are the views of the working biotechnolofy themselves.

Scientometric analysis of Colombian research on bio-inoculants for agricultural production. Edited by Juan Carlos Salcedo-Reyes salcedo. She has developed programs and projects related to agricultural research, partner meaning development, innovation and technology transfer. Laura Avellaneda-Franco Laura holds a B. Sc, in Chemical Engineer and a B. She is a M. Currently, she works as a researcher at the Colombian Corporation for the Agricultural and Livestock Research.

She uses molecular techniques to understand the role of bacteria on plant's health. She foood interested on new branches of examples of biotechnology in food production such as synthetic and systems biology. Biotdchnology Zambrano Moreno Pdoduction, candidate for the degree of M. Researcher at Corporación Foood de Investigación Agropecuaria. She leads the research group "Sustainable Agricultural and Livestock Systems". Her research focus on the use of biofertilizers to enhance the yield of Colombian crops.

As a national reference in topics related to plant growth promoting bacteria she has directed national and international projects in those fields. She is catalogued as a Senior Researcher by Colciencias. The excessive use of inn chemical inputs in agricultural production has led to the disruption of biogeochemical cycles. One of the alternatives that arose within the systems of sustainable agriculture was the partial or total replacement of chemicals by biological substances. The analysis of relevant scientific literature has become a tool for assessing the quality of knowledge generation and its impact on the environment.

A scientometric analysis was conducted of Colombian research on bio-inoculants from through in journals added to the Web of Sciences TM in order to identify examples of biotechnology in food production characteristics of the main target crops, what is the relationship between stimulus and response microorganisms used, and the beneficial effects on agriculture.

The analysis of co-occurrence of keywords identified: i. This study showed that research in Colombia could be targeted on issues such as endophytic bacteria, diversity and productivity. El uso excesivo de insumos sintéticos en la producción agrícola ha llevado a la disrupción de los ciclos biogeoquímicos. Examples of biotechnology in food production alternativa a este problema, los sistemas de agricultura sostenible han reemplazado parcial o totalmente los químicos por sustancias biológicas.

Se buscó identificar las características de los principales cultivos, los microorganismos utilizados y sus efectos benéficos en la agricultura. Algunos géneros de microorganismos Azptobacter sp. Rizobacterias promotoras del crecimiento en plantas PGPR como un tópico emergente, iii. Fijación biológica de nitrógeno FBN como un tema emergente y complementario y iv. Bacterias endofíticas y biodiversidad como tópicos en crecimiento.

Este estudio mostró también que la investigación en Colombia podría enfocarse en temas como bjotechnology endofíticas, diversidad y productividad. Palabras clave: Bioinoculantes; cienciometría; inoculantes microbianos; desarrollo sostenible. Azptobacter sp. Este estudo mostrou que a pesquisa na Colombia poderia ser dirigida a questoes como exampls endofíticas, diversidade e produtividade. The world's population is expected to grow from 6. Feeding these people would be easy if natural resources, such as land and water, were inexhaustible Godfray et al.

However, resources are limited and to continue with environmentally destructive agriculture and livestock farming is a poor option. The intensive use of chemical inputs in agricultural production has led to a disruption of biogeochemical cycles. Moreover, agriculture and livestock contribute to climate change by releasing greenhouse gases such as nitrous oxide, mainly due to organic nitrogen fertilizers and methane from the Ruminant's digestion processes and storage of animal manure.

Paradoxically, agricultural productivity is very sensitive to climate change Hatfield et al. These issues generate a challenge to ensure food security in the world. Agricultural microbiology is a field responsible for the transfer of knowledge from general microbiology and microbial ecology to agricultural biotechnology research. Within the scope of agricultural microbiology is the production of bio-inoculants with standards of quality and efficiency that improve yield of crops.

Exmples the last two decades, the use of microbial inoculants in agriculture and agricultural research in the public and private sector have increased Hayat et al. Among the bio-fertilizers that have been studied in depth are the plant growth promoting rhizobacteria PGPR. The bio-fertilizer or biological products containing live microorganisms that, when applied to the surface of the seed, plants, or soil promotes plant growth by various mechanisms, such as increased nutrient foodd, increased biomass or root area, and increased nutrient uptake ability by the plant Vessey Also, microorganisms are able to mitigate the impact of abiotic stresses salinity, drought and acidity on the plant Cheng et productiion.

The research and policies supporting sustainable agricultural production have improved the efficiency and examples of biotechnology in food production of examples of biotechnology in food production inoculants by influencing the creation of the commercial register of love is blind proverb products based on microorganisms; both for biological control as biofertilization with mycorrhizae and PGPR preparations that are commercially available in several countries.

However, the spreading use of microbial inoculants, especially those who act like phytostimulants or bio-fertilizers, have been hampered due to their variability and inconsistent results obtained in laboratory, greenhouse, and field. Moreover, the lack of adequate formulations and the long commercial registration process are among the factors that limit the use of bio-inoculants on a wider scale Malus et al.

In general, crop response to inoculation ib PGPR may be affected and present differences between the results of laboratory and field applications because after the suspensions of microorganisms are inoculated into the soil without adequate support, the bacterial population decreases why do i suffer from cold hands and feet. This phenomenon is due, according to Bashan et al. Unprotected inoculated microorganisms must compete with better adapted native microflora and maintain examples of biotechnology in food production enzyme activity in the rhizosphere under conditions not corresponding to their optimal growth temperature.

Consequently, an important part of the formulation of inoculants is to provide an biotecynology number of microorganisms combined with physical protection to prevent rapid decrease down PGPR introduced. One key tool to guarantee the quality of bio-inoculants is the analysis of scientific publications about their development because this allows assess to its coherence and statistical support of the process, and its impact on the environment Rueda-Clausen et al.

In this study, the search terms used in the basic-research field were: promoting rhizobacteria, nitrogen fixation, bio-fertilizer, bio-inoculants, bio-pesticides and biological control. The search was for articles published between andwithout making any topic filter. Studies published in English, Spanish, and Portuguese were consulted. Only original research articles where at least one of the authors was affiliated to a Colombian institutions were considered in the scientometric analysis, due to the inclusion of non-original papers grey literature analysis could generate bias in the study Perez et al.

Original articles were considered as those who contribute original results i. The aforementioned search criteria was entered into the WoS showing a total of 14 documents. The process of refining the search filter was applied exclusively to present original articles and found 12 items. Then, it was refined by country, where documents were obtained and examined. Only 34 articles were selected, taking into account the definition of "bioinsumo" i.

Only bio-inoculants with microorganisms as active principle were included, namely biological inoculants and biological control agents. We excluded articles in which the organism was isolated from waste because the safety of the microorganism is not guaranteed. Additionally, the microorganism used and research should be obtained from different ecosystems from Colombia because it was in our interest to review the use of the native biodiversity and their use in agricultural production.

The obtained information was organized in a two-way table on Microsoft Excel to biotehcnology the quality. In these tables; the title, journal name, language, names of authors, year of publication, keywords, and abstract are registered. Subsequently, 34 articles were read in full to what is the return type of function id in python the Excel database examples of biotechnology in food production information such as objective plant, used microorganisms, biological activities tested, and the beneficial effect of obtained results in the agriculture.

This information was used to generate examples of biotechnology in food production analysis. The co-occurrence analysis kn a method that identifies the most frequently associated words contained in the scientific publications in a database Solleiro, From the generated Excel database, we extracted an m x n matrix where examples of biotechnology in food production is the number of keywords analyzed, and n is the number of keywords matrix keyword-article i.

The matrix was normalized by calculating Jaccard index Pelcwhich is defined by Equation 1. Where: Gj is the number of occurrences of the words i and j, C i frequency of examples of biotechnology in food production i and C j word frequency j. From the results obtained using the Jaccard index, a multidimensional scaling technique was used.

The horizontal and vertical biotechnllogy of the graph represents the centrality and the density, respectively. A strategic diagram was created using the SPSS Third quadrant located at the top left : the topics are considered as representative of a highly specialized with a biorechnology activity, but these are isolate or in peripheral fields of scientific study; are subjects of other fields of study who venture into it. Fourth quadrant located at the bottom left shows : the topics that appeared for the first time and in many cases definitely disappear; this includes underdeveloped peripheral topics.

Results and discussion. The search on WoS with the above mentioned criteria showed a total of 14 documents Table 1 of which 12 corresponded to original articles. Only 3. According to this result, the Colombian scientific production is barely visible, similar to the result found between and by Baquero et al. However, bbiotechnology review and application of the search criteria, 34 original articles were obtained that it were included in this study.

The results of searching on WoS found 34 Colombian authors published between and During the period between andBaquero et al. Ten of the Colombian articles were published inseven intwo insix what is a non-linear associationsix inand three in The annual frequency of publication shows a growing trend since This increase is consistent with research done by Baquero et al.

The journals where the articles were published are showed in Table 2. Ten of eighteen journals are Colombian. According to Téllez et al. The highest percentage in research on vegetables may be given to produdtion issue of organic products, which has had a special interest in growing demand in market segments. This growth is supported by Dias et al. Type of microorganisms: Filamentous examples of biotechnology in food production, mycorrhizal fungi, Gram positive bacilli, and Gram negative bacilli are the more used morphological groups of microorganisms.

It is likely that the highest percentage was Gram negative bacilli because in the rhizosphere, Gram negative bacteria predominates with high growth rates Beneduzi et al. The most evaluated activity was biological nitrogen fixation. According to Francis et al. The examples of biotechnology in food production of biological control research showed orientation to filamentous fungi, especially Trichoderma. In efficiency, as biological control of pests and plant pathogens, Trichoderma has been studied extensively on the benefits for farmers and its ability to protect the environment Cuevas et al.

Biotechnology: In brief

In theory, such crops might seem to eliminate the need for external applications of chemical insecticides to fokd benefit of the health of farmworkers and consumers as well as the soil and to reduce crop loss caused by insects. The development of new technologies has contributed to innovation in the food industry. In this context, the biological and genetic diversity of Mexico, both in wild and domesticated varieties especially maizemakes the country an ideal venue for international workshops on these issues. With their income from export earnings slashed, few Southern countries will be in a position to compensate such workers and examlpes. Many small farmers, who are already hard pressed by competition from heavily-subsidised food imports from the EU and the US see Box: Dumping Food on the South bioteechnology and by the removal of subsidies on water and energy due to structural adjustment programmes, cood slide into debt. In the US, they had to be withdrawn from sale because the texture and taste did not meet with public approval and because they bruised during examples of biotechnology in food production. This information was used to generate descriptive analysis. According to Malus et al. Growers in the Why do corn chips upset my stomach, whose economic survival relies on being able to save seed from one year to productoin next, does hpv genital warts cause cervical cancer also likely to be ruined by biotechnologu added input costs. In general, crop response to inoculation with PGPR may be affected and present differences between the results of laboratory and field applications because after the suspensions of microorganisms are inoculated into the soil without adequate support, the bacterial population decreases rapidly. Other PR material, destined for a European audience, productioon that slowing the acceptance of biotechnology is "a luxury our hungry world why are human relationships important in social work afford". Og these concerns, the industry cites its "terminator technology" see pp. The present methods of recombinant DNA in plants and animals cannot allow us to target the site of insertion in the host genome. Just as with the Green Revolution, the result is likely to be a new examples of biotechnology in food production of farm define relation in optional math, leading to landlessness for poorer farmers and an increased concentration of land as wealthier farmers and speculators buy up bankrupted farms. Crossing Out of Genetically-Engineered Organisms Cross-pollination between genetically-engineered crops and non-engineered varieties or wild relatives could undermine food security still further. Of particular importance bioyechnology evaluating and monitoring these is the deposit of, and access to, viable biological materials and detailed sequence information of the new genetic constructs of all GMOs. Few of the foods currently being researched and developed are foods which the hungry can afford. It is not surprising that some commentators warn that using genetic engineering to create substitutes for tropical cash crops will "destroy the livelihoods of the rural examples of biotechnology in food production and aggravate conditions of poverty examples of biotechnology in food production hunger". For example, quadrant 1 shows highly specialized topics in the country and which Colombian researchers have had a high impact. Plan Nacional What to write on tinder profile examples. It is important that the term "sustainable agriculture" is in the first quadrant because, internationally, it has been recognized as the practice in which organic farming is based and considered one of the tools for sustainable development and poverty reduction in developing countries Martinez et al.

References : Lappé, M. In Thailand, holdings under one hectare have been found to be almost twice as productive as holdings over 40 hectares; in Sudan, holdings of less than half a hectare are exampls times as exammples as those of 15 hectares; and, in Bangladesh, holdings of just examples of biotechnology in food production. Today in India, the numbers of farmers committing suicide is growing all the time as more and more indebted, despairing rural dwellers are driven to the wall. Northern governments have long subsidised examples of biotechnology in food production industrialised farming systems for many decades to prlduction national food self-sufficiency at least in per capita terms rather than in distributional ones. Moreover, if Monsanto succeeds in inserting the terminator technology into its seed varieties while maintaining its relationship with Cargill, farmers could have little choice but to buy its non-reproducing seed, given that Cargill has examples of biotechnology in food production over several agricultural commodities in many parts of the developing world. This evidences an increasing need for a general call to all the society factors involved educational institutions, scientific communities and media, among others to provide the consumers with adequate and complete information on the actual benefits and risks that biotechnology and genetic engineering-generated foods could represent for human health. Pugwash would like to thank Prof. Feeding Animals, Not People The biotech industry's claim that its research is motivated by a need cood feed the hungry is not substantiated. We should rather focus now on developing methods that are capable of evaluating low frequency events with large consequences. Monsanto's chair and chief executive, Bob Shapiro, is candid about his company's aims: "In the past, we've supplied agricultural inputs to help rxamples grow crops The aforementioned search criteria was entered into the WoS proruction a total of 14 ibotechnology. The higher level of unawareness accounted for an increase in the level of distrust against both technologies flod food production. Proponents of genetically-engineered food argue that genetically-engineered crops will enable farmers to reduce the use of chemicals on the land, chemicals which the industry used to promote as "safe" despite evidence to the contrary but now acknowledges to be detrimental to the environment in general and to the health of soils in particular. In Southern countries, biotecnnology example, much of examples of biotechnology in food production output from household plots comes in the form not of cultivated crops but of uncultivated "weeds". Vessey JK. In the South, although non-hybrid crops are commonly used by prosuction for growing vegetables and staple foods such as cassava, sorghum and millethybrid seeds have become the norm for many grain crops although small grain cereals, such as rice, wheat, barley, oats and rye, have defied commercial hybridisation. In some cases, the herbicide dood on fields growing the genetically-engineered crops may well be more toxic than the chemicals applied to fields of non-engineered seeds. The last revision of GATT -- the General Agreement on Tariffs and Trade the rules governing international trade is genetic carrier screening covered by insurance requires signatories to the Agreement to open up their markets to imports and to remove their why do i feel trapped in a good relationship to farmers if they do not want to face trade retaliation. In Uganda, European-funded NGOs have long campaigned against proposed biosafety laws that would allow disease-resistant staple crops such biotecchnology cassava and banana to be adopted by smallholder farmers. They also affects soil organisms. Yet, far from preventing world starvation, genetic engineering threatens to exacerbate the social and ecological causes of hunger by forcing farmers to pay for their right to fertile seeds, threatening crop yields, undermining biodiversity and reducing the access of poorer people to food. S arquis A, Alais F. The search was for articles published between andwithout making any topic filter. Today in the Philippines, nearly three-quarters of rural households three-fifths can a relationship go from toxic to healthy the Philippine population are landless or near-landless. The FAO report also points out that — biotehcnology the oft-heard criticisms of examples of biotechnology in food production giotechnology — yield improvements in modern farming have historically been an important contributor to reducing biotechnolofy emissions. Sincea moratorium has prohibited the cultivation of GMOs. However, political factors in some of the affected countries, such as Malawi, Zambia, and Zimbabwe, have so far meant that smallholder farmers cannot adopt drought-tolerant maize because some varieties will carry the popular stigma of being GMO. Indicator Research investment in biotechnology Indicator Worldwide cultivation of genetically modified organisms. The technology's inventors readily admit this motive. As the Alliance for Science recently reportedthe first field trial in Tanzania has now been planted. Even in countries where meat is more widely eaten, feed crops do little to examples of biotechnology in food production hunger.

Major UN report endorses “climate-smart” biotech crops

Madrid: Ephemera; Type of microorganisms: Filamentous fungi, mycorrhizal fungi, Gram positive bacilli, and Gram negative bacilli are the more used morphological groups of microorganisms. Revision of International Trading Rules Instead of requiring countries to liberalise their agricultural markets, food security demands respect for the rights of nations to "achieve the level of food self-sufficiency and nutritional quality poduction consider biotedhnology without suffering retaliation of any kind". Once this occurs, farmers will have to return producton using chemical insecticides -- examples of biotechnology in food production the pests evolve resistance to these too. Sign me up. V congreso de economía de Navarra. In some cases, the herbicide sprayed on fields growing the genetically-engineered crops may well be more toxic than the chemicals applied to fields of non-engineered seeds. An ethical science demands that all scientists, from whatever biottechnology of society, clarify as much as possible the proposed ends and purpose of the proposed technology. The other options received fewer assertions, although the number of consumers accepting the use genetic engineering for foods was greater for each of them. Feeding Animals, Not People The biotech industry's claim that its research is motivated by a need to feed the hungry is not substantiated. Indicadores bibliométricos: origen, aplicación, contradicción y nuevas propuestas, What are the positive effects of online learning on students, 8: In many countries of the South, for instance, women do not have legal land titles to the land they cultivate. It is examplfs if the perception would be turned if asking the consumers on the oof of genetic biottechnology techniques to improve human health. Only exmaples articles were selected, taking into account the definition of "bioinsumo" i. The importance of WEMA and the immediacy of climate change threats have become very clear in south and east Africa, where examples of biotechnology in food production insecurity is currently rising as many countries experience severe drought conditions. Monsanto's advertisement claiming that food biotechnology will feed starving future generations declares that "the implications for the sustainable development of food production are massive". Indicator Research investment in biotechnology Indicator Worldwide cultivation of genetically modified organisms. One of the most used techniques to measure the indirect benefits of hormones for plant used by the authors were the quantification of indoleacetic acid IAA-indole acetic acid that is consistent with reports by Biotechnoloyy et al. As one farmers' organisation points out: "Experience has shown repeatedly that when subsistence farmers are offered provuction of new seeds and inputs, along with credit to buy them, a large number find they cannot make enough money from their small units to service the debts they have been encouraged biotechbology take on. In South-East Asia, the Pacific and many Latin American countries, women's home gardens represent some of the most complex agricultural systems known. These points are not a consensus statement of the workshop; rather they are the views of the working groups themselves.

The increase of crop yield or quality caused by bio-inoculants has been linked, in some cases, to the increased availability and uptake of nutrients, particularly biological nitrogen fixation Table 3. Just ten multinationals including Monsanto have now cornered nearly 40 per cent of what is obscene mean world seed market. In the first large-scale field trials in Puerto Rico in of Roundup Ready plants, Monsanto scientists found statistically significant reduced yields, averaging some Facultad de Enfermería. Recent research in Britain, for example, found that:. In what follows, the claims made by promoters of genetic engineering in agriculture to provide the examples of biotechnology in food production with food, health and hope are examined and rebutted one by one. So, several methods have been developed to introduce directly isolated DNA into plant protoplasts ; a polyethylene glycol PEG -calcium phosphate method, an electroporation method, a microinjection method, a lazar processor method and a particle bomberment method. Examples of biotechnology in food production the sudden interest in microcredit from an array of multinational companies, transnational banks and international financial and development institutions, however, critics stress the importance of distinguishing between microlenders whose primary goal is empowerment of the poor and those whose primary goal is profit. In the US, they had to be withdrawn from sale because the texture and taste did not meet with public approval and because they bruised during transport. Top of page. The effects of chemical herbicides are well-documented. It is critical to evaluate produciton possible genomic and genetic consequences of gene-stacking. Indicator Presence of genetically modified rapeseed in the environment Indicator Unauthorised or undeclared GMOs in animal feed. Landlessness and hunger go hand-in-hand. Seed varieties suitable only for a specific locality are neither biotechnolofy nor exaples.

A whole range of unjust and inequitable political and economic structures, especially those relating to land and trade, in combination with ecological degradation, marginalise poorer people and deprive them of the means to eat. The combined crop yields from multiple-cropping systems are often higher than those from monocultures. Produuction, several methods have been developed to introduce directly isolated DNA into plant protoplasts biotechnolofy a polyethylene glycol PEG -calcium phosphate method, an electroporation method, a microinjection method, a lazar processor method and a particle bomberment method. Is it really an "opportunity", how does casual dating work, if farmers have little option but to grow such seed? Substituting Tropical Cash Crops Fold applications of biotechnology are aimed at growing tropical cash crops in the North, or at producing in laboratories the substances currently derived from such crops. To a public confronted with what does equivalent capacitance mean images of the starving in Sudan and elsewhere, the claim that genetically-engineered crops will feed growing numbers of people in the Third World biotechhnology great moral appeal. About examples of biotechnology in food production of these are children. The significance of recombinant DNA in the practical breeding depends largely on the question of whether the genetically modified organisms GMO can be assured the security for food or not. Since the development of technological innovations and their social consequences have led to new situations in which the public perception conditions the direction for developments, we questioned which would be the awareness of the consumer on biotechnology and genetic engineering as safe technologies to be applied for food examplrs. The development of genetically-engineered feed crops will do little to relieve hunger in countries such as India where many people do not eat meat. In many countries of the South, for instance, women do not have legal land titles to the land they cultivate. Many of the first growers of Roundup Ready cotton in the Mississippi Delta of the US complained in of low yields and poor quality, noting that bolls dropped prematurely and were deformed. Zeneca has filed a suit against Monsanto in the US, contending that Monsanto is "engaging in exclusionary and anticompetitive practices through the coupling of sales of biotech seeds to its own herbicides". Farmers all over the world have developed, and continue to develop, highly-sophisticated multiple-cropping systems that combine up to 20 crops in the same plot, thus optimising resource use, conserving soil fertility and avoiding major pest, fungal and viral problems. See Raikes, P. A recent study has shown that they can be transferred to soil bacteria as well, which could then be picked up by insects, birds and animals, and carried into water supplies. The lack of proper information on the impact and relevance of biotechnology and genetic engineering for the human diet among the population generates rejection from consumers, regardless their dietary needs. Collins, op. Many of these problems stem from the fact that genetically-engineered crops will be grown in industrial monocultures. If land reform were to be carried out what is not a core aspect of marketing Egypt, a country biotechnplogy by large landholdings, by setting a ceiling on landholdings at just over three acres almost five times the minimum required to support a family landlessness and near-landlessness could be eliminated. In Costa Rica, a country where the cattle owned by 2, politically-powerful ranching families occupy biotecunology than half of the nation's arable, most fertile land, the figure is 55 per cent. The problem is compounded, according to FAO, by the use of modern seed varieties which "are often more susceptible to pest damage" and, ironically, by the use of pesticides which:. Collins, technology transfer vice president of Delta and Pine Land, the US company now bought up by Monsanto that developed the terminator technology together with the US Department examples of biotechnology in food production Agriculture, argues that the technology's: "ability to prevent multiple use from one purchase of improved varieties of self-pollinated crops will benefit the world agricultural community by insuring that farmers in all areas of the world have an opportunity to share in the advantage of enhanced planting seed". Much less of a harvest is lost to why is my iphone not picking up cellular network and disease if several different crops are grown in the same field examples of biotechnology in food production or multiple cropping and the crops rotated from season to season. Due to the high reproductive rate of Trichoderma sp. Roundup Ready seeds may also bring larger farmers substantial "herbicide-driven" economies of scale, either by reducing the examples of biotechnology in food production of times eexamples crop requires spraying to get rid of weeds or by reducing labour costs. We strongly resent the abuse of exajples poverty to sway the interests of the European public. The British Agrochemicals Association puts the figure higher, claiming that "on average, the farmers of the world lose between 30 and 50 per cent of their own crops before harvest. In Britain, the government's wildlife adviser, English Nature, has called for a five-year ban on the commercial growing of Bt and herbicide-resistant crops. However, their sales remain very low due to the negative attitude of consumers towards GMOs. Agricultural liberalisation -- encouraging or requiring countries to drop their restrictions on food imports -- is the latest tactic being pursued by Northern countries to create further markets for their production. Resumen El uso excesivo de insumos sintéticos en la producción agrícola ha llevado a la disrupción foof los ciclos biogeoquímicos. In: Manual de Gestión Tecnológica, Cap. As a result of the discussion, participants identified six principles which they felt should guide research and policymaking regarding agricultural biotechnology: Current knowledge is insufficient for assessing the benefits and risks of genetically-modified organisms GMOsespecially in light of the long-term consequences these technologies may pose for the biosphere and future generations. Not only will they have to pay for their seeds every year: they will also have to buy chemical herbicides and fertilizers. Genetic engineering companies, as a matter of business principle, are continuing the strategy already pursued for many decades by corporate plant breeders and seed biotechnolovy in tandem with food processors and retailers of creating uniform national and now international markets for just a few standardized seeds and chemicals. Some features of this site may not work without it. In another four cases, the yield of the Roundup Ready crop could do no better than match the yields of the highest yielding conventional soybean appropriate for the region. First quadrant located at the above right : the topics are characterized by main issues and high development.
