Book Description
Bacillus thuringiensis cotton, in short Bt cotton, sparks both interest and debate in most of us almost simultaneously. Bt refers to a toxin that contains Cry1Ac protein gene, which, when genetically engineered into a hybrid cotton seed, makes the cotton

Book Description
This book explores the risks and benefits of crops that are genetically modified for pest resistance, the urgency of establishing an appropriate regulatory framework for these products, and the importance of public understanding of the issues. The committee critically reviews federal policies toward transgenic products, the 1986 coordinated framework among the key federal agencies in the field, and rules proposed by the Environmental Protection Agency for regulation of plant pesticides. This book provides detailed analyses of: Mechanisms and results of genetic engineering compared to conventional breeding for pest resistance. Review of scientific issues associated with transgenic pest-protected plants, such as allergenicity, impact on nontarget plants, evolution of the pest species, and other concerns. Overview of regulatory framework and its use of scientific information with suggestions for improvements.

Book Description
The food, feed, ?ber, and fuel needs of the changing world pose the challenge of doubling or tripling of world food, feed, and ?ber production by the year 2050 to meet the needs of a 11 billion global population. In addition, the dramatic changes in food prices in the recent years further warrant that production and productivity need to be enhanced to ensure adequate supplies. Biotechnology can make a signi?cant contribution to this effort as demonstrated by cotton and other crops; the new advances in biotechnology have made it possible to develop plants that contain genes that were not possible to be developed by sexual means. Cotton has been a leader in the use of biotechnology. With the introduction of Bt cotton, followed by stacked cotton products (insect and herbicide tolerance) and extensive use of molecular breeding tools, cotton cultivation has been much improved. The contributions in this book illustrate the scienti?c advances that are going on in cotton and the impact they continue to deliver for all cotton growers. Twelve percent of the global cotton area is now under biotech products at 15. 5 million ha. The primary bene?ts from using genetically engineered cotton include reduced insecticide use, lower production costs, improved yields, lower farming risks, and increased opportunities to grow cotton in areas of severe pest infestation.

Book Description
Bacillus thuringiensis (Bt) cotton was introduced in India in 2002 and is the only genetically modified (GM) crop commercially available in the country. The technology faced enormous arguments before and after the official introduction in the country. The author presents the sustainability of effects over time based on unique panel data set of 5 years generated from 3 waves of survey. The study extends beyond the traditional farm level analysis by highlighting the advantages of panel data econometrics in studying technology adoption and impacts. Results suggest that Bt cotton technology is very successful in India. The technology has resulted in higher net impacts on cotton yields and profits. Both small-and large-scale farmers in India are very satisfied with the innovation. Government interventions into pricing of transgenic seeds and policy implications are discussed.

Book Description
Biotechnology can bring major breakthroughs in agriculture. The book examines the experience of introduction of biotechnology in Indian agriculture, specifically, examining the performance of Bt cotton versus non-Bt cotton across India’s major cotton states, namely Andhra Pradesh, Gujarat, Maharashtra and Tamil Nadu, which together account for nearly 70 percent of the country’s cotton production. Major advances in biotechnology have made it possible to directly identify genes, determine their functions, and transfer them from one organism to another. The advances have spawned many technologies and Bt cotton is one important outcome. Bt cotton has become one of the most widely cultivated transgenic crops and is currently grown in 21 countries - 11 developing and 10 industrialized countries. The Government of India was relatively late in permitting biotechnology, only approving the cultivation of three transgenic Bt cotton hybrids from April 2002. Many concerns were raised about their performance there was strong opposition from some quarters. In India, Gujarat and Maharastra were the first states to adopt them, followed by Andhra Pradesh, Karnataka, Tamil Nadu and Madhya Pradesh. Based on a sample of 694 farming households, the book examines and analyzes the performance on the yields, pesticide costs, seed costs, overall production costs and profits. It also reports on the environmental impacts, satisfaction with the technology and ways of improving its performance.

Book Description
Bollworm is the major pest in cotton plants. BT Cotton is the first genetically modified crop which contains a gene (cry1Ac) of a soil bacterium i.e. Bacillus thuringiensis (BT) that will produce a natural toxin to act against bollworm. The aim of the BT introduction is to minimize the pesticide dosages and improve the crop production to achieve agriculture growth, poverty alleviation and environmental protection. The contents of the book emphasizes on the socio-economic status of the farmers and their livelihoods and on environment with the introduction of the transgenic cotton.
