ISBN: 0309437385
Category : Science
Languages : en
Pages : 607

Book Description
Genetically engineered (GE) crops were first introduced commercially in the 1990s. After two decades of production, some groups and individuals remain critical of the technology based on their concerns about possible adverse effects on human health, the environment, and ethical considerations. At the same time, others are concerned that the technology is not reaching its potential to improve human health and the environment because of stringent regulations and reduced public funding to develop products offering more benefits to society. While the debate about these and other questions related to the genetic engineering techniques of the first 20 years goes on, emerging genetic-engineering technologies are adding new complexities to the conversation. Genetically Engineered Crops builds on previous related Academies reports published between 1987 and 2010 by undertaking a retrospective examination of the purported positive and adverse effects of GE crops and to anticipate what emerging genetic-engineering technologies hold for the future. This report indicates where there are uncertainties about the economic, agronomic, health, safety, or other impacts of GE crops and food, and makes recommendations to fill gaps in safety assessments, increase regulatory clarity, and improve innovations in and access to GE technology.

Book Description
Karnataka is one of the nine major Bt cotton growing states in the country. The Bt cotton seed production focussed on the socio-economic characteristics of contract farmers, cost and return, efficiency of resource use and problems faced by the farmers in Bt cotton seed production under different companies. Five companies having highest area under Bt cotton seed production were selected for study. The present study was conducted with primary data collected entirely based on a multistage random sampling technique from 200 Bt cotton seed production growers who have contracted with the different seed companies. The study pertained to the agricultural year 2012-13. The total cost of Bt cotton seed production varied from one company contract farmers to other company contract farmers. The total cost was found to be higher (Rs.96829) in case of JK seeds company contract farmers followed by the farmers who have contracted with Monsanto seeds company (Rs.95797). While, the net returns obtained from Bt cotton seed production was found to be higher in case of Monsanto seeds company contract farmers (Rs.46387) followed by Kaveri seeds company contract farmers (Rs.33076). The Cobb-Douglas production function revealed that the farmers who have contracted with different seed companies, the use of seed was found to be optimum across all company contract farmers. Whereas, fertilizer resource was over utilized by farmers who have contracted with various companies. Non availability of trained labour and prevalence of high wage rate were the major constraints in case of production, where as poor technical assistance and low contract price were the contractual problems. The other problems regarding plant protection, high incidence of diseases was the major constraint in Bt cotton seed production and in case of marketing, high price of parents of Bt cotton seeds and low price of the seeds offered by the agencies were the major ones. Therefore the Bt cotton seed production technology had positive impact on Socio- economic status of farmers by increase in yield and reducing cost on inputs thereby increase in income and also standard of living.

Economic impact and implications of biotechnology

Book Description
Biotechnology and the introduction of genetically modified (GM) crops are providing new opportunities for increasing crop productivity and tackling agricultural problems, such as pests and diseases, abiotic stresses and nutritional limitations of staple food crops. Cultivation of GM crops is changing the practice of agriculture and there is an increasing trend in cultivation of GM crops worldwide. Plants with novel traits to produce pharmaceutical products are also being generated. The safety of GM crop cultivation and use is a topic of extreme international debate. Biotechnology innovations appear to have taken world agriculture by storm. This spectacular success is attributable almost entirely to transgenic varieties of four crops: soybean, corn, cotton, and canola. It is noteworthy that in 2013, the number of countries cultivating biotech crops reached the historical milestone of 28 countries. In 2013, the global hectarage of biotech crops continued to grow strongly reaching 175 million hectares, up from 160 million hectares in 2011. In 2012, the global market value of biotech crops was US$14.84 billion, (up from US$13.35 billion in 2011). Manjunath Kerur (2012) conducted a study on comparative economic analysis of Bt cotton and Desi cotton cultivation in Haveri district of Karnataka. The results on the per acre cost incurred and returns obtained from Bt cotton and Desi cotton cultivation revealed that the variable and fixed costs were higher in Bt cotton producing farms (Rs. 11748) and (Rs. 4049) compared to Desi cotton producing farms (Rs. 13202) and (Rs.3634) respectively. The gross returns and net returns from Bt cotton cultivation were Rs. 32096 and Rs. 15113 per acre, respectively as against Rs. 24140 and Rs. 6007 per acre from Desi cotton cultivation. In India, policy of encouraging genetically modified cotton needs a complete review and critical examination from the point of view of environment, diversity and health.

Cultivating Knowledge

Cultivating Knowledge PDF Author: Andrew Flachs
Publisher: University of Arizona Press
ISBN: 0816539634
Category : Social Science
Languages : en
Pages : 241

Book Description
A single seed is more than just the promise of a plant. In rural south India, seeds represent diverging paths toward a sustainable livelihood. Development programs and global agribusiness promote genetically modified seeds and organic certification as a path toward more sustainable cotton production, but these solutions mask a complex web of economic, social, political, and ecological issues that may have consequences as dire as death. In Cultivating Knowledge anthropologist Andrew Flachs shows how rural farmers come to plant genetically modified or certified organic cotton, sometimes during moments of agrarian crisis. Interweaving ethnographic detail, discussions of ecological knowledge, and deep history, Flachs uncovers the unintended consequences of new technologies, which offer great benefits to some—but at others’ expense. Flachs shows that farmers do not make simple cost-benefit analyses when evaluating new technologies and options. Their evaluation of development is a complex and shifting calculation of social meaning, performance, economics, and personal aspiration. Only by understanding this complicated nexus can we begin to understand sustainable agriculture. By comparing the experiences of farmers engaged with these mutually exclusive visions for the future of agriculture, Cultivating Knowledge investigates the human responses to global agrarian change. It illuminates the local impact of global changes: the slow, persistent dangers of pesticides, inequalities in rural life, the aspirations of people who grow fibers sent around the world, the place of ecological knowledge in modern agriculture, and even the complex threat of suicide. It all begins with a seed.

Application of conjoint analysis in agricultural economics research

Book Description
Conjoint Analysis is a statistical technique where respondents ranked preferences for different offers are decomposed to determine the person’s inferred utility function for each attribute and the relative importance of each attribute. It is a versatile marketing research technique that can provide valuable information for new product development and forecasting, market segmentation and pricing decisions, advertising and distribution, competitive analysis and repositioning. The aims of conjoint analysis were to identify attribute combinations which confer the highest utility to the consumers and to establish the relative importance of attributes in terms of their contribution to total utility. There are 5 basic steps to be taken by a Researcher interested in applying conjoint analysis namely Problem formulation, Determining the product profile, Sampling plan, Data collection and Analysis and interpretation of the results. Conjoint measurement is based on the assumptions that a product can be described according to levels of a set of attributes and the consumer’s overall judgment in respect to that product is based on these attributes level. This analysis is based on three models like Part -Worth Model, Vector Model and Ideal Point Model. An attempt was made to analyze the consumer preference of ragi using conjoint analysis in Bengaluru and Vijayapura districts of Karnataka. The results reveal that, among all the attributes of ragi studied in Bengaluru urban, fineness was found to be most important and first consideration of consumers accounting for 23.80 per cent of relative importance with superfine ragi having the utility of 1.45. In case of Bengaluru rural, price was found to be most important and first deliberation, accounting for 30.60 per cent of relative importance.Among all the attributes studied in ragi in Vijayapura urban, colour was found to be most significant and first consideration, accounting for 30.33 per cent. In case of Vijayapura rural, fineness was found to be the first contemplation and most important, accounting for 33.91 per cent of relative importance. Dhamotharan et. al. (2015), conducted a study using conjoint analysis to analyze consumers’ preferences for geographic indications (GI) bananas. The results show that consumers prefer GI bananas for their medicinal properties, natural production method, and lower price premium.Mangala (2010), conducted a study on Impact of food retail chains on producers, consumers and retailers. The results showed that, among all the attributes studied, quality of the produce found to have the highest relative importance of 33.8 per cent, with a preference for premium quality (utility value 2.77). Importance of 26.89 per cent was given to location of the outlet, with preference for nearness of the shop had utility value 2.16.Consumers are becoming more aware of the quality attributes of different commodities they are consuming, and consequently are choosing products that closely match their tastes and preferences. Demand for food products has increased among the consumers for a variety of reasons: unique quality, locality, supporting local producers. Researchers and managers in agricultural and food industries often face problems relating to new product development, forecasting, market segmentation and pricing decisions, advertising and distribution, competitive analysis and repositioning. So a conjoint measurement study can assist them in solving these problems.

Languages : en
Pages : 190

Book Description
The production, trade and consumption of pulses have seen substantial growth over the last fifteen years. This report examines the trends and patterns of this growth, and the factors that explain these for different kinds of pulses. The report presents an analysis of trends of consumption of pulses in different regions of the world and discusses the role that pulses can play in human nutrition. The report presents an analysis of the dynamics of growth of major pulses in different pulse-producing countries of the world. It describes the increasingly important role of trade in the global economy of pulses and presents an analysis of changing patterns of trade. The report argues that there is a pressing need to close the large gap between potential and actual yields, particularly on smallholder farms in South Asia and sub-Saharan Africa, by increased adoption of improved varieties and modern agronomic practices in all developing countries. This in turn requires a major thrust in agricultural research and extension, improving credit availability, and public investment directed at pulse production. The report discusses future prospects and policy imperatives for sustaining the growth of pulse production.

Diversification of Agriculture in Eastern India

Diversification of Agriculture in Eastern India PDF Author: Madhusudan Ghosh
Publisher: Springer
ISBN: 813221997X
Category : Business & Economics
Languages : en
Pages : 242

Book Description
Divided into three parts - Rationale and Extent of Agricultural Diversification, Nature and Problems of Agricultural Diversification, and Food and Livelihood Security through Agricultural Diversification, this edited book examines various aspects of agricultural diversification in Eastern India. In recent years, Indian agriculture has been diversifying from cereals to high-value crops and livestock products in accordance with the changing consumption patterns. As such, it faces the challenges of a new economic regime, besides the usual problems of rising population, unemployment and poverty, declining investments in the agriculture sector and degradation of natural resources. These issues are discussed in the book in light of the significant transformation in the economic structure of the Indian economy from agriculture to non-agriculture (industry and services) and changing cropping pattern from cereals to non-cereals, in accordance with the changing consumption pattern. The book would be of interest to teachers, researchers, policymakers, students and general readers having an interest in agricultural development in India.
