In the past, scientific research has predicted a decrease in the effectiveness of Bt cotton due to the rise of secondary and other sucking pests. It is suspected that once the primary pest is brought under control, secondary pests have a chance to emerge due to the lower pesticide applications in Bt cotton cultivars. Studies on this phenomenon are scarce. This article furnishes empirical evidence that farmers in China perceive a substantial increase in secondary pests after the introduction of Bt cotton. The research is based on a survey of 1,000 randomly selected farm households in five provinces in China. We found that the reduction in pesticide use in Bt cotton cultivars is significantly lower than that reported in research elsewhere. This is consistent with the hypothesis suggested by recent studies that more pesticide sprayings are needed over time to control emerging secondary pests, such as aphids, spider mites, and lygus bugs. Apart from farmers' perceptions of secondary pests, we also assessed their basic knowledge of Bt cotton and their perceptions of Bt cotton in terms of its strengths and shortcomings (e.g., effectiveness, productivity, price, and pesticide.

In recent decades, China has undergone rapid economic growth, industrialisation and urbanisation concomitant with deep and extensive structural and social change, profoundly reshaping the country’s development landscape and urban-rural relationships. This book applies livelihoods approaches to deepen our understanding of the changes and continuities related to rural livelihoods within the wider context of political economy of development in post-socialist China, bridging the urban and rural scenarios and probing the local, national and global dynamics that have impacted on livelihood, in particular its mobility, security and sustainability. Presenting theoretically informed and empirically grounded research by leading scholars from across the world, this book offers multidisciplinary perspectives on issues central to rural livelihoods, development, welfare and well-being. It documents and analyses the processes and consequences of change, focusing on social protection of mobile livelihoods, particularly rural migrants’ citizenship rights in the city, and the environmental, social and political aspects of sustainability in the countryside. This book contributes to the current scholarly and policy debates, and is among the first attempts to critically reflect on China’s market transition and the associated pathways to change. It will be of interest to students in international development studies, China studies, social policy, public health, political science, and environmental studies at undergraduate and postgraduate levels, as well as academics, policy makers and practitioners who are concerned with China’s human and social development in general, and agriculture and rural livelihoods in particular.
Globalization has impacted many aspects of life, and the food chain is no exception. Approximately one-quarter of America's food supply is imported, and while food production and manufacturing companies financially benefit from sourcing food from other countries, regulating these food sources becomes increasingly difficult. How does food regulation and inspection differ between countries? What can be done to ensure food imported from other countries is safe for consumption, and how can we make sure people involved in the food production process around the world are treated ethically? Readers will explore the many considerations affecting the global food chain.
A wide-ranging, interdisciplinary exploration of key topics that interrelate pest management, public health and the environment This book takes a unique, multidimensional approach to addressing the complex issues surrounding pest management activities and their impacts on the environment and human health, and environmental effects on plant protection practices. It features contributions by a distinguished group of authors from ten countries, representing an array of disciplines. They include plant protection scientists and officers, economists, agronomists, ecologists, environmental and public health scientists and government policymakers. Over the course of eighteen chapters, those experts share their insights into and analyses of an array of issues of vital concern to everyone with a professional interest in this important subject. The adverse effects of pest control have become a subject of great concern worldwide, and researchers and enlightened policymakers have at last begun to appreciate the impact of environmental factors on our ability to manage pest populations. Moreover, while issues such as pesticide toxicity have dominated the global conversation about pest management, economic and societal considerations have been largely neglected. Environmental Pest Management: Challenges for Agronomists, Ecologists, Economists and Policymakers is the first work to provide in-depth coverage of all of these pressing issues between the covers of one book. Offers a unique multi-dimensional perspective on the complex issues surrounding pest management activities and their effect on the environment and human health Addresses growing concerns about specific pest management strategies, including the use of transgenic crops and biological controls Analyses the influence of global processes, such as climate change, biological invasions and shifts in consumer demand, and ecosystem services and disservices on pest suppression efforts Explores public health concerns regarding biodiversity, pesticide use and food safety Identifies key economic drivers of pest suppression research, strategies and technologies Proposes new regulatory approaches to create sustainable and viable crop protection systems in the framework of agro-environmental schemes Offering a timely and comprehensively-unique treatment of pest management and its environmental impacts in a single, inter-disciplinary volume, this book is a valuable resource for scientists in an array of disciplines, as well as government officials and policymakers. Also, teachers of undergraduate and graduate level courses in a variety of fields are sure to find it a highly useful teaching resource.
This book analyzes international and Chinese regulatory approaches addressing environmental risks that may be caused by GM crops and examines how China implements its international obligations in its policies and laws. Using the legal doctrinal method, the book discusses the precautionary principle and the public involvement principle, as well as several legal measures at the international law level and in Chinese law. It observes that legal principles and measures as provided for in China’s GMO legal framework have generally implemented the international obligations regarding the prevention of environmental risks that may be caused by the cultivation of GM crops and related activities. However, the book argues that Chinese law lacks an explicit codification of the precautionary principle, and the same is true with regard to public participation; the regulatory framework lacks specific obligations. It concludes that future research should focus on the application and enforcement of the relevant Chinese legislation, and that it is also important to investigate how the environmental risks that may be caused by new techniques, such as genome-editing techniques, could be prevented, given the experience gained by regulating the cultivation of GM crops and related activities.
Potato (Solanum tuberosum L.) is the fourth-largest food crop produced in the world with approximately 370 million tonnes. This product is a staple in many diets throughout the world and the underground swollen tubers of the plant are rich sources of proteins, carbohydrates, minerals (K, Mn, Mg, Fe, Cu and P), and vitamins (C, B1, B3, B6, K, folate, pantothenic acid). Improvement of new potato cultivars resistant to biotic and abiotic factors is extremely important, as these are the main reasons for decreased potato production. Seed tuber production and tuber storage under healthy conditions after harvest are two important issues in potato cultivation. As such, this book discusses the importance of the potato plant and examines ways to increase its production and develop new cultivars resistant to stress factors via conventional and biotechnological methods.
Reflections on feeding body and spirit in a world of change Animal scientists have long considered domestic livestock to be too dumb to know how to eat right, but the lifetime research of animal behaviorist Fred Provenza and his colleagues has debunked this myth. Their work shows that when given a choice of natural foods, livestock have an astoundingly refined palate, nibbling through the day on as many as fifty kinds of grasses, forbs, and shrubs to meet their nutritional needs with remarkable precision. In Nourishment Provenza presents his thesis of the wisdom body, a wisdom that links flavor-feedback relationships at a cellular level with biochemically rich foods to meet the body’s nutritional and medicinal needs. Provenza explores the fascinating complexity of these relationships as he raises and answers thought-provoking questions about what we can learn from animals about nutritional wisdom. What kinds of memories form the basis for how herbivores, and humans, recognize foods? Can a body develop nutritional and medicinal memories in utero and early in life? Do humans still possess the wisdom to select nourishing diets? Or, has that ability been hijacked by nutritional “authorities”? Consumers eager for a “quick fix” have empowered the multibillion-dollar-a-year supplement industry, but is taking supplements and enriching and fortifying foods helping us, or is it hurting us? On a broader scale Provenza explores the relationships among facets of complex, poorly understood, ever-changing ecological, social, and economic systems in light of an unpredictable future. To what degree do we lose contact with life-sustaining energies when the foods we eat come from anywhere but where we live? To what degree do we lose the mythological relationship that links us physically and spiritually with Mother Earth who nurtures our lives? Provenza’s paradigm-changing exploration of these questions has implications that could vastly improve our health through a simple change in the way we view our relationships with the plants and animals we eat. Our health could be improved by eating biochemically rich foods and by creating cultures that know how to combine foods into meals that nourish and satiate. Provenza contends the voices of “authority” disconnect most people from a personal search to discover the inner wisdom that can nourish body and spirit. That journey means embracing wonder and uncertainty and avoiding illusions of stability and control as we dine on a planet in a universe bent on consuming itself.
