Biomass obtained from agricultural residues or forest can be used to produce different materials and bioenergy required in a modern society. As compared to other resources available, biomass is one of the most common and widespread resources in the world. Thus, biomass has the potential to provide a renewable energy source, both locally and across large areas of the world. It is estimated that the total investment in the biomass sector between 2008 and 2021 will reach the large sum of $104 billion. Presently bioenergy is the most important renewable energy option and will remain so the near and medium-term future. Previously several countries try to explore the utilization of biomass in bioenergy and composite sector. Biomass has the potential to become the world s largest and most sustainable energy source and will be very much in demand. Bioenergy is based on resources that can be utilized on a sustainable basis all around the world and can thus serve as an effective option for the provision of energy services. In addition, the benefits accrued go beyond energy provision, creating unique opportunities for regional development.The present book will provide an up-to-date account of non-wood, forest residues, agricultural biomass (natural fibers), and energy crops together with processing, properties and its applications to ensure biomass utilization and reuse. All aspects of biomass and bioenergy and their properties and applications will be critically re-examined. The book consists of three sections, presenting Non wood and forest products from forestry, arboriculture activities or from wood processing, agricultural biomass (natural fibers) from agricultural harvesting or processing and finally energy crops: high yield crops and grasses grown especially for energy production."

This book is a compilation of the most challenging and significant chapters on the diagnosis and management of important bacterial, fungal, viral, viroid, phytoplasma, non parasitic diseases and various physiological disorders, in various crops. The chapters have been contributed by eminent plant pathologists, having wide experience of teaching and research on various crops with different types of diseases, which cause great economic losses. The book would be very useful for students, teachers and researchers of plant pathology. This book highlights recent advances made in the development of new types of resistance in host plants and alternative strategies for managing plant diseases to improve food quality and reduce the negative public health impact associated with plant diseases. Having entered into 21st century advancements in the Diagnosis of Plant Pathogens and Plant Disease Management need to be closely examined and adequately applied, so that newer challenges facing plant pathology could be adequately addressed in attaining food security for the growing population. Substantial advancements have been made in terms of expanding knowledge base of the biology of plant-microbial interactions, disease management strategies and application and practice of Plant Pathology. Application of molecular biology in Plant Pathology has greatly improved our ability to detect plant pathogens and in increasing our understanding, their ecology and epidemiology. Similarly, new technologies and resources have been evolved for the development of sustainable crop protection systems by different control strategies against various pests and pathogens that are important components of the integrated pest management programme. Natural products and chemical compounds discovered as a result of basic research and molecular mechanisms of pathogenesis have led to the development of "biorational" pesticides. Biological control has been found to be the most significant approach to plant health management during the twentieth century and promises using modern biotechnology, to be even more significant in the twenty-first century.

Chopped in salads, scooped up in salsa, slathered on pizza and pasta, squeezed onto burgers and fries, and filling aisles with roma, cherry, beefsteak, on-the-vine, and heirloom: where would American food, fast and slow, high and low, be without the tomato? The tomato is representative of the best and worst of American cuisine: though the plastic-looking corporate tomato is the hallmark of industrial agriculture, the tomato's history also encompasses farmers' markets and home gardens. Garden Variety illuminates American culinary culture from 1800 to the present, challenging a simple story of mass-produced homogeneity and demonstrating the persistence of diverse food cultures throughout modern America. John Hoenig explores the path by which, over the last two centuries, the tomato went from a rare seasonal crop to America's favorite vegetable. He pays particular attention to the noncorporate tomato. During the twentieth century, as food production, processing, and distribution became increasingly centralized, the tomato remained the king of the vegetable garden and, in recent years, has become the centerpiece of alternative food cultures. Reading seed catalogs, menus, and cookbooks, and following the efforts of cooks and housewives to find new ways to prepare and preserve tomatoes, Hoenig challenges the extent to which branding, advertising, and marketing dominated twentieth-century American life. He emphasizes the importance of tomatoes to numerous immigrant groups and their influence on the development of American food cultures. Garden Variety highlights the limits on corporations' ability to shape what we eat, inviting us to rethink the history of our foodways and to take on our opportunity to expand the palate of American cuisine.

Biointensive Integrated Pest Management in Horticultural Ecosystems (Hardcover, 2014 ed.): P. Parvatha Reddy Biointensive Integrated Pest Management in Horticultural Ecosystems (Hardcover, 2014 ed.)

Through Green Revolution in late 1960s, India achieved self-sufficiency in food production, but still the country has not achieved self-sufficiency in production of horticultural crops. Most of the growth in food production during the green revolution period is attributed to the use of higher levels of fertilizers and pesticides which are continuing to destroy stable traditional ecosystems. The challenge before the crop protection scientist is to increase yields from the existing land without harming the environment and resource base. This can be achieved by adopting eco-friendly Biointensive Integrated Pest Management (BIPM) strategy.

BIPM incorporates ecological and economic factors into agricultural system design and decision making, and addresses public concerns about environmental quality and food safety. The benefits of implementing BIPM can include reduced chemical input costs, reduced on-farm and off-farm environmental impacts, and more effective and sustainable pest management. An ecology-based IPM has the potential of decreasing inputs of fuel, machinery, and synthetic chemicals-all of which are energy intensive and increasingly costly in terms of financial and environmental impact. Such reductions will benefit the grower and society.

The present book deals with the most recent biointensive integrated approaches for pest management utilizing components such as bioagents predators, parasitoids and pathogens (bacteria, fungi, viruses)], botanicals (biofumigation, oil cakes, FYM, compost, crop residues, green manuring and other organic amendments), arbuscular mycorrhizal fungi, physical methods (hot water treatment of planting material, soil solarization), cultural methods (crop rotation, summer ploughing, fallowing, intercropping, pruning, mulching, spacing, planting date, trap cropping, "etc."), biorational chemicals (pheromones) and resistant cultivars. This book can serve as a useful reference to policy makers, research and extension workers, practicing farmers and students. The material can also be used for teaching post-graduate courses."

Not many young farmers of the early nineteenth century left diaries that have come down to us, still fewer from Shropshire, at a time when country life continued much as it had since long before the Industrial Revolution. In June 1835, twenty-three-year-old Peter Davis set out from his home in the Teme valley on a mini grand tour. As befitted a son of the soil, his eye lighted first upon the current agricultural scene. Not surprisingly, however, it was the great cities of Liverpool and Edinburgh that came to take more of his attention. The young man's travel diary represents a vivid snapshot of his experiences in passing through the north of England and southern Scotland during the reign of King William IV. Complemented by Peter Davis' narrative, it describes the day-to- day events of his life at home during 1836-7, culminating in his beloved father's death. Before the advent of railways every journey from Peter's home in Burford was significant and through this diary, it has been possible to flesh out the history of a family and imagine ourselves living the lives of past generations. The diaries have been edited by one of their author's great-great grandsons. Martin Davis. He draws comparisons in his introductory essay between the changes affecting the landscape at the time of the diaries and those we face today. This wonderful book will be of interest to Shropshire residents, family historians and all those with a concern and love for country life in pre-industrial times.

Plant-parasitic nematodes are recognized as one of the greatest threats to crop production throughout the world. Estimated annual crop losses of $8 billion in the United States and $78 billion worldwide are attributed to plant parasitic nematodes. Plant parasitic nematodes not only cause damage individually but form disease-complexes with other microorganisms thereby increasing crop loss. Nematode diseases of crops are difficult to control because of their insidious nature and lack of specific diagnostic symptoms which closely resemble those caused by other plant pathogens and abiotic diseases. Future developments of sustainable management systems for preventing major economical agricultural losses due to nematodes is focused on strategies that limit production costs, enhance crop yields, and protect the environment. This book presents a first compendium and overview for nematode problems and their management across North America. Each chapter provides essential information on the occurrence and distribution of plant parasitic nematodes, their major crop hosts, impact on crop production and sustainable management strategies for each region of the continent including, Canada, Mexico and all states of the USA. For each region, a thematic overview of changes in crop production affected by plant parasitic nematodes and their management strategies over time will provide invaluable information on the important role of plant parasitic nematodes in sustainable agriculture.

The Biology of Reaction Wood (Hardcover, 2012): Barry A. Gardiner, John Barnett, Pekka Saranpaa, Joseph Gril The Biology of Reaction Wood (Hardcover, 2012)
Barry A. Gardiner, John Barnett, Pekka Saranpaa, Joseph Gril
R4,039 R3,237 Discovery Miles 32 370 Save R802 (20%) Shipped within 7 - 12 working days

The book is a fundamental reference source on reaction wood for wood scientists and technologists, plant biologists, silviculturists, forest ecologists, and anyone involved in the growing of trees and the processing of wood. It brings together our current understanding of all aspects of reaction wood, and is the first book to discuss both compression wood and tension wood.

Trees produce reaction wood to maintain the vertical orientation of their stems and the optimum angle of each branch. They achieve this by laying down fibre cell walls in which differences in physical and chemical structure from those of normal fibres are expressed as differential stresses across the stem or branch. This process, while of obvious value for the survival of the tree, causes serious problems for the utilisation of timber. Timber derived from trees containing significant amounts of reaction wood is subject to dimensional instability on drying, causing twisting, bending and splitting. It is also difficult to work as timber, and for the pulp and paper industry the cost of removing the increased amount of lignin in compression wood is substantial. This has both practical and economic consequences for industry.

Understanding the factors controlling reaction wood formation and its effect on wood structure is therefore fundamental to our understanding of the adaptation of trees to their environment and to the sustainable use of wood.

The topics covered include:

-Morphology, anatomy and ultrastructure of reaction wood

-Cell-wall polymers in reaction wood and their biosynthesis

-Changes in tree proteomes during reaction wood formation

-The biomechanical action and biological functions of reaction wood

-Physical and mechanical properties of reaction wood from the scale of cell walls to planks

-The detection and characterisation of compression wood

-Effects of reaction wood on the performance of wood and wood-based products

-Commercial implications of reaction wood and the influence of forest management on its formation

The Law and Governance of Water Resources - The Challenge of Sustainability (Hardcover): Douglas Fisher The Law and Governance of Water Resources - The Challenge of Sustainability (Hardcover)
Douglas Fisher
R2,719 Discovery Miles 27 190 Shipped within 7 - 12 working days

This path-breaking book focuses on the law and legal doctrine within the wider policy context of water resources and analyses the concept of sustainability. To achieve the sustainable use and development of water resources is a daunting challenge for both global and local communities. It requires commitments from all groups within international, national and local communities from their own particular, possibly conflicting, perspectives. Without a set of coherent legal arrangements designed to ensure effective governance of water resources, their sustainable use and development is unlikely to be achieved. Douglas Fisher considers how legal arrangements for managing water resources have evolved across the continents over hundreds of years. He explores their relevance for contemporary society; how the norms of current international and national legal regimes are responding; and, most importantly, how legal rights and duties should be structured so as to achieve sustainability in the future. This detailed textual and linguistic analysis of legal doctrines and instruments in relation to water resources will be invaluable for international and national water resources policy analysts, water resource managers and water resource lawyers. Students of water resource management, sustainable development and sustainability will also find this book of great interest to them.

This book provides complete, comprehensive, and broad subject-based reviews for students, teachers, researchers, policymakers, conservationists, and NGOs interested in the biodiversity and conservation of woody plants. Forests cover approximately 31 percent of the world's total landmass; 93 percent is natural forest and only 7 percent consists of planted trees. Forest decline is progressing at an alarming rate worldwide. In addition to human activities (logging, deforestation, and exploiting forest lands for agriculture and industrial use), a number of other factors - including pests and diseases, drought, soil acidity, radiation, and ozone - are cumulatively contributing to global forest decline. The present situation forces us to focus on forest conservation strategies for the present and future. Gene conservation and maintaining genetic diversity in forest ecosystems are crucial to the preservation of forest genetic resources. This calls for integrated action to implement both the in situ (on site) preservation of forest stands and ex situ (distant from the original site) strategies for the conservation of woody plants' genetic resources. Selected priority areas include: 1) assessing patterns of genetic diversity and threats, 2) understanding the biological processes regulating genetic diversity, 3) assessing the impact of human activities and climate change on genetic diversity, and 5) finding methods for prioritizing species and populations for the conservation of forest trees genetic resources. All chapters were written by leading scientists in their respective fields, which include: woody plant diversity, ecology and evolution; assessment of genetic diversity in forest tree populations; conservation planning under climate change; and in situ and ex situ strategies, including biotechnological approaches, for the conservation of woody plants genetic resources.

This book introduces readers to nearly 600 common weeds. In addition to essential information, each chapter includes photos for a specific type of weed to show its morphology in different growth periods, such as seedling, root, flower, fruit, and mature plant. The book also discusses control measures, including agricultural, chemical, physical, biological, and comprehensive methods. The Volume 3 mainly focuses on 252 Species of Dicotyledonous and Monocotyledonous Weeds along with 2 Species of Liverworts and Mosses. With the development of society and economics, weeds have become a recurring problem. In particular, the exotic, invasive, and quarantine weeds have spread dramatically and rapidly. On the other hand, many people, even those who are engaged in weed control, do not (or cannot) distinguish between weeds. Thus there is significant demand for illustrations of weed morphologies, as well as information on their control measures. This book offers a valuable, practical guide for all those working in the fields of crop cultivation, plant protection and quarantine management.

Leguminous crops have been found to contribute almost 27% of the world s primary crop production. However, due to environmental fluctuations, legumes are often exposed to different environmental stresses, leading to problems with growth and development, and ultimately, decreased yield. This timely review explains the transcriptomics, proteomics, genomics, metabolomics, transgenomics, functional genomics and phenomics of a wide range of different leguminous crops under biotic and abiotic stresses, and their genetic and molecular responses. Amongst others the text describes the effect of nutrient deficiency, pesticides, salt, and temperature stress on legumes.

2018 Nebraska Book Award 2018 Outstanding Academic Title, selected by Choice Homesteading the Plains offers a bold new look at the history of homesteading, overturning what for decades has been the orthodox scholarly view. The authors begin by noting the striking disparity between the public's perception of homesteading as a cherished part of our national narrative and most scholars' harshly negative and dismissive treatment. Homesteading the Plains reexamines old data and draws from newly available digitized records to reassess the current interpretation's four principal tenets: homesteading was a minor factor in farm formation, with most Western farmers purchasing their land; most homesteaders failed to prove up their claims; the homesteading process was rife with corruption and fraud; and homesteading caused Indian land dispossession. Using data instead of anecdotes and focusing mainly on the nineteenth century, Homesteading the Plains demonstrates that the first three tenets are wrong and the fourth only partially true. In short, the public's perception of homesteading is perhaps more accurate than the one scholars have constructed. Homesteading the Plains provides the basis for an understanding of homesteading that is startlingly different from current scholarly orthodoxy.
