Book Description
Once a humble orphan existing in the shadows of the brutal Establishment, Lucian (3zLucky(3y Spark has evolved from lone vigilante to (3zThe Torch Keeper," a fiery symbol of the valiant resistance. Lucky now leads the heroic fight to restore justice and liberty to the downtrodden survivors of a world devastated by geological catastrophe and tyranny. But as the Torch Brigade prepares to launch a final, desperate gambit against the ruthless forces controlled by his former companion, the mysterious Cassius Thorn, Lucky struggles with the secret of his own true identity. Is he the spark of hope destined to unite a nation and finally end this destructive crusade? Or is he truly the dark catalyst of the past, intent on reducing the remnants of humanity to smoldering embers? With the fates of his brainwashed brother, Cole, and genetically transformed love, Digory Tycho, caught in the crossfire of epic war, Lucky's final choice may have apocalyptic consequences for an entire world.

Book Description
Over the past decade, we have witnessed a growing scarcity of and competition for water around the world. As the demand for water for domestic, municipal, industrial, and environmental purposes rises in the future, less water will be available for agriculture. But the potentials for new water resource development projects and expanding irrigated area are limited. We must therefore find ways to increase the productivity of water used for irrigation. This paper reviews the literature on irrigation efficiency and on the potential for increasing the productivity of water in rice-based systems. It stresses the continuing confusion over the concepts of irrigation efficiency and water productivity. It identifies the reasons for the wide gap between water requirement and actual water input (both irrigation diversions and rainfall) in irrigated rice production systems and discusses potential opportunities for increasing water productivity both on-farm and at the system level. Based on the reported low farm and system level irrigation efficiencies, the potentials for water savings in rice production appear to be very large. But we do not know the degree to which various farm and system interventions will lead to sustainable water savings in the water basin until we can quantify the downstream impact of the interventions. Studies on the economic benefits and costs, and environmental aspects of alternative interventions are also lacking. This paper emphasizes the need to measure the productivity of water at farm, system, and basin levels, and to understand how the productivity at one level relates to the productivity at another. Without water balance studies to measure productivity at these different scales, it is not possible to identify the potential economic benefits of alternative interventions and the most appropriate strategies for increasing irrigation water p productivity in rice-based systems.

Book Description
This open access book is about understanding the processes involved in the transformation of smallholder rice farming in the Lower Mekong Basin from a low-yielding subsistence activity to one producing the surpluses needed for national self-sufficiency and a high-value export industry. For centuries, farmers in the Basin have regarded rice as “white gold”, reflecting its centrality to their food security and well-being. In the past four decades, rice has also become a commercial crop of great importance to Mekong farmers, augmenting but not replacing its role in securing their subsistence. This book is based on collaborative research to (a) compare the current situation and trajectories of rice farmers within and between different regions of the Lower Mekong, (b) explore the value chains linking rice farmers with new technologies and input and output markets within and across national borders, and (c) understand the changing role of government policies in facilitating the on-going evolution of commercial rice farming. An introductory section places the research in geographical and historical context. Four major sections deal in turn with studies of rice farming, value chains, and policies in Northeast Thailand, Central Laos, Southeastern Cambodia, and the Mekong Delta. The final section examines the implications for rice policy in the region as a whole.

Book Description
This book addresses aspects of rice production in rice-growing areas of the world including origin, history, role in global food security, cropping systems, management practices, production systems, cultivars, as well as fertilizer and pest management. As one of the three most important grain crops that helps to fulfill food needs all across the globe, rice plays a key role in the current and future food security of the world. Currently, no book covers all aspects of rice production in the rice-growing areas of world. This book fills that gap by highlighting the diverse production and management practices as well as the various rice genotypes in the salient, rice-producing areas in Asia, Europe, Africa, the Americas, and Australia. Further, this text highlights harvesting, threshing, processing, yields and rice products and future research needs. Supplemented with illustrations and tables, this text is essential for students taking courses in agronomy and production systems as well as for agricultural advisers, county agents, extension specialists, and professionals throughout the industry.

Book Description
This open access book on straw management aims to provide a wide array of options for rice straw management that are potentially more sustainable, environmental, and profitable compared to current practice. The book is authored by expert researchers, engineers and innovators working on a range of straw management options with case studies from Vietnam, the Philippines and Cambodia. The book is written for engineers and researchers in order to provide them information on current good practice and the gaps and constraints that require further research and innovation. The book is also aimed at extension workers and farmers to help them decide on the best alternative straw management options in their area by presenting both the technological options as well as the value chains and business models required to make them work. The book will also be useful for policy makers, required by public opinion to reduce greenhouse gas emissions and air pollution, looking for research-based evidence to guide the policies they develop and implement.

Book Description
The book covers the various aspects of the use of pesticides, their behavior, degradation, and impacts in wetland ricefields, and presents the results of surveys conducted in the Philippines and Thailand. It includes both bibliographic reviews and selected aspects of the experimental results of a research project on pesticide impacts in wetland ricefields. The first phase of the `Pesticide Impact' project was developed in the Philippines from 1989 to 1991. It was a multidisciplinary/collaborative approach involving scientists from IRRI, NRI (England), ORSTOM (France), UPLB (Philippines) who studied the effects of pesticides on the environment and on farmers' health, and the economical aspects of their use.
