Book Description
Agriculture remains the most important sector for promoting economic growth in developing countries. In agriculture-based economies, the sector accounts for about 29% of the gross domestic product (GDP) and employs 65% of the labor force (World Bank, 2007). About 75% of the world’s poor live in rural areas, where agriculture is the main economic activity. Crosscountry comparison shows that GDP growth induced by agriculture is at least twice as effective in reducing poverty as GDP growth outside agriculture (World Bank, 2007). Agriculture is, therefore, imperative in reducing mass poverty and food insecurity in developing countries.

Book Description
Insect pests remain one of the main constraints to food and fiber production worldwide despite farmers deploying a range of techniques to protect their crops. Modern pest control is guided by the principles of integrated pest management (IPM) with pest resistant germplasm being an important part of the foundation. Since 1996, when the first genetically modified (GM) insect-resistant maize variety was commercialized in the USA, the area planted to insect-resistant GM varieties has grown dramatically, representing the fastest adoption rate of any agricultural technology in human history. The goal of our book is to provide an overview on the role insect-resistant GM plants play in different crop systems worldwide. We hope that the book will contribute to a more rational debate about the role GM crops can play in IPM for food and fiber production.

Book Description
"In a recent survey of 820 Boro (winter rice), potato, bean, eggplant, cabbage, sugarcane, and mango farmers in Bangladesh, over 47 percent of farmers were found to be overusing pesticides. With only 4 percent of farmers formally trained in pesticide use or handling, and over 87 percent openly admitting to using little or no protective measures while applying pesticides, overuse is potentially a threatening problem to farmer health as well as the environment. To model pesticide overuse, the authors used a 3-equation, trivariate probit framework, with health effects and misperception of pesticide risk as endogenous dummy variables. Health effects (the first equation) were found to be strictly a function of the amount of pesticides used in production, while misperception of pesticide risk (the second equation) was determined by health impairments from pesticides and the toxicity of chemicals used. Pesticide overuse (the third equation) was significantly determined by variation in income, farm ownership, the toxicity of chemicals used, crop composition, and geographical location. The results highlight the necessity for policymakers to design effective and targeted outreach programs that deal specifically with pesticide risk, safe handling, and averting behavior. Ideally, the approach would be participatory in nature to address key informational gaps, as well as increasing a farmers' awareness retention. The results also point to specific crops and locations experiencing a higher prevalence of overuse-bean and eggplant in general-and overall production in the districts of Chapainawabganj, Chittagong, Comilla, Jessore, Narshingdi, Rajshahi, and Rangpur. Focusing efforts in these crop and geographical areas may have the most measurable effects on pesticide overuse. "--World Bank web site.

Book Description
Overall goal of this paper is to re-examine findings of earlier efforts that analysed the effect of Bt cotton adoption in 1999 with two follow-up surveys conducted in 2000 and 2001. Our survey data on yields and econometric analyses indicate that the adoption of Bt cotton continues to increase output per hectare in 2000 and 2001 and that the yield gains extend to all provinces in our sample. More importantly, Bt cotton farmers also increased their incomes by reducing use of pesticides and labour inputs. Finally, survey data shows that Bt cotton continues to have positive environmental impacts by reducing pesticide use. We provide evidence that farmers have less health problems because of reduced pesticide use. We conclude with evidence that China is not unique and that there are lessons for other developing countries in their experience.

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
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 genetic modification of crops continues to be the subject of intense debate, and opinions are often strongly polarised. Environmental Impact of Genetically Modified Crops addresses the major concerns of scientists, policy makers, environmental lobby groups and the general public regarding this controversial issue, from an editorially neutral standpoint. While the main focus is on environmental impact, food safety issues, for both humans and animals are also considered. The book concludes with a discussion on the future of agricultural biotechnology in the context of sustainability, natural resource management and future global population and food supply.

Book Description
"The WHO Recommended Classification of Pesticides by Hazard was approved by the 28th World Health Assembly in 1975 and has since gained wide acceptance. When it was published in the WHO Chronicle, 29, 397-401 (1975), an annex, which was not part of the Classification, illustrated its use by listing examples of classification of some pesticidal active ingredients and their formulations. Later suggestions were made by Member States and pesticide registration authorities that further guidance should be given on the classification of individual pesticides. Guidelines were first issued in 1978, and have since been revised and reissued every few years. Up until the present revision the original guidelines approved by the World Health Assembly in 1975 have been followed without amendment. In December, 2002 the United Nations Committee of Experts on the Transport of Dangerous Goods and on the Globally Harmonized System of Classification and Labelling of Chemicals (UNCETDG/GHS) approved a document called 'The Globally Harmonized System of Classification and Labelling of Chemicals' with the intent to provide a globally-harmonized system1 (GHS) to address classification of chemicals, labels, and safety data sheets. The GHS (with subsequent revisions) is now being widely used for the classification and labeling of chemicals worldwide. For this revision of the Classification the WHO Hazard Classes have been aligned in an appropriate way with the GHS Acute Toxicity Hazard Categories for acute oral or dermal toxicity as the starting point for allocating pesticides to a WHO Hazard Class (with adjustments for individual pesticides where required). It is anticipated that few of the more toxic pesticides will change WHO Hazard Class as a result of this change. As has always been the case, the classification of some pesticides has been adjusted to take account of severe hazards to health other than acute toxicity (as described in Part II). The GHS Acute Toxicity Hazard Category for each pesticide is now presented alongside the existing information"--Page 1.

Book Description
Agriculture is one of the most ancient and significant sectors of India, the only means of living for almost two-third of the employed class in India. It has occupied almost 43 percent of India's geographical area. India is one of the major cotton producing countries, ranking 3rd after USA and China. Cotton accounts per 30 percent of agricultural Gross Domestic Product (GDP) in India and has the largest cotton area of 20 million acres. It provides livelihood to more than 60 million people in India. As agriculture is closely associated with the environment, it has a major impact on land use, soil, water biodiversity and the landscape and the intensive agriculture has disrupted ecological balance. Green revolution in India was ushered with the increased use of pesticide and increased input of agricultural fertilizers and using better farm techniques in spite of increase in food production, many of agriculture farmers of India are not aware of the environmental hazards occurred due to the usage of pesticides. The farmers of India are using one-third of pesticides that are consumed in third world countries.
