Interactions between agriculture, climate and patterns of land use are complex. Major changes in agriculture, and land use patterns are foreseen in the next couple of decades in response to shifts in climate, greenhouse gas management initiatives, population growth and other forces. The book explores key interactions between changes in agriculture, patterns of land use and efforts to reduce greenhouse emissions from agriculture. The volume is based on inter-disciplinary science and policy interactions, exploring the way land use may aid in addressing or be affected by the onset of climate change and alterations in food demand. Future forces shaping land use decisions are examined, and its sensitivity to climate change is highlighted. Patterns of land use and the agricultural role in climate change mitigation are explored. Also, policy and social responses to the new perspectives on future land use patterns are identified. The perspective of the book is beyond the year 2015.
Summer farms occur throughout the world where there are rich pastures that can only be utilised for part of the year, mainly because they are under snow and ice during the winter. In Europe transhumance is often a major event when the cattle and other livestock leave their home villages and move up into the mountains, and likewise on their return. The best known sites in Europe are perhaps those found in the Alpine areas, but they occur everywhere where there are suitable highland areas to exploit. Traditionally they have been the subject of the studies of ethnographers and anthropologists, especially in the second half of the 20th century when technological and economic changes led to the gradual abandonment of the farms and to other ways of exploiting the highlands. The last of these farmers are gradually disappearing and with them the oral records and memories. Now it is archaeologists who are leading the recording of this material and also looking at the history of such farming from prehistory and from the Bronze Age with the rise in importance of 'Secondary Products' such as cheese which could be stored for use over winter.Much of the evidence can only be gathered by surface survey and by excavation, though in some cases there are good written sources which have yet to be fully exploited. This volume provides case studies, as well as brief summaries of other projects in Europe, extending from the Black Sea in the east to northern Spain and Iceland in the west, though with a concentration on the Alpine area. One thing that emerges is the very varied nature of these sites in terms of their chronology, who went to the farms, the distances travelled, and the other activities associated with transhumance such as mining. In some cases the products were primarily for the subsistence of the agricultural population, but in other cases they were traded and could produce a large amount of profit. This is the first overview of these sites in Europe written from an archaeological point of view.
Our requirement for plant breeders to be successful has never been greater. However one views the forecasted numbers for future population growth we will need, in the immediate future, to be feeding, clothing and housing many more people than we do, inadequately, at present. Plant breeding represents the most valuable strategy in increasing our productivity in a way that is sustainable and environmentally sensitive. Plant breeding can rightly be considered as one of the oldest multidisciplinary subjects that is known to humans. It was practised by people who first started to carry out a settled form of agriculture. The art, as it must have been at that stage, was applied without any formal underlying framework, but achieved dramatic results, as witnessed by the forms of cultivated plants we have today. We are now learning how to apply successfully the results of yet imperfect scientific knowledge. This knowledge is, however, rapidly developing, particularly in areas of tissue culture, biotechnology and molecular biology. Plant breeding's inherent multifaceted nature means that alongside obvious subject areas like genetics we also need to consider areas such as: statistics, physiology, plant pathology, entomology, biochemistry, weed science, quality, seed characteristics, repro ductive biology, trial design, selection and computing. It therefore seems apparent that modern plant breeders need to have a grasp of wide range of scientific knowledge and expertise if they are successfully to a exploit the techniques, protocols and strategies which are open to them.
The chapters collected here explore a number of different issues, including the operation of the tariff-rate quotas established under the Uruguay Round Agreement, the implications of sanitary and phytosanitary restrictions on trade, and the growing controversy over genetically modified organisms. In addition, several chapters analyze the interaction between agricultural trade and environmental concerns. The relative prosperity in U.S. agriculture that attended the passage of the Federal Agriculture Improvement and Reform Act of 1996 was followed by a general decline in U.S. agricultural prices from 1998 to 2000. This trend in declining prices continues through the year 2001, despite the movement toward more liberalized agricultural trade. Trade liberalization has been the result of a variety of factors, including the implementation of the Uruguay Round Agreement, and the establishment of a variety of regional trade agreements, such as the North America Free Trade Agreement. Needless to say, in the face of falling agricultural prices and increasingly liberalized agricultural trade, the agricultural policy scene is an extremely complex one, both locally and globally. This volume does not pretend to offer a single, systematic prescription for what the next agricultural policy should be. Rather, the arguments and analyses contained herein are intended to highlight several issues that must be considered in the continuing debates on agricultural policy.
This book's purpose is to shed light on the threats and opportunities arising from the incentives and restrictions of governmental actions which food industry managers discover in their search for profits. The food industry, as defined here, includes farmers, their input suppliers, processors and distributors. This text explores how the private sector reacts to the stimulus of public support measures, rules and regulations which are usually motivated by entirely different ends than those desired within the private sector. No current single model of economic behavior as yet adequately encompasses or quantifies these complex vectors and forces. Management is comprised of many factors, most of which can be identified ex post but few of which can be appraised precisely ex ante. The perceptual processes by which managers respond to governments are influenced by culture, aptitudes, individual and collective goals. details of most government/business relationships are discussed Few openly since management and government officials are, understandably, often reluctant to share the decision tree route by which trust is built and understandings are negotiated. Our text differs from others in that we combine both a theoretical and experiential approach to the subject. The insights provided by the case study material give a more macro and yet realistic view than tha t usually offered elsewhere. We indicate the risks and dynamics of the situations faced by management while also showing the importance and strategic relevance of a solid analytical foundation for managerial purposes.
Since the mid-1970s, the tropical savanna, known as Cerrado, has been transformed into one of the world's largest grain-growing regions. This book explores how and by what Brazil achieved inclusive and sustainable growth in the Cerrado.
Since the beginning of agricultural production, there has been a continuous effort to grow more and better quality food to feed ever increasing popula tions. Both improved cultural practices and improved crop plants have allowed us to divert more human resources to non-agricultural activities while still increasing agricultural production. Malthusian population predictions continue to alarm agricultural researchers, especially plant breeders, to seek new technologies that will continue to allow us to produce more and better food by fewer people on less land. Both improvement of existing cultivars and development of new high-yielding cultivars are common goals for breeders of all crops. In vitro haploid production is among the new technologies that show great promise toward the goal of increasing crop yields by making similar germplasm available for many crops that was used to implement one of the greatest plant breeding success stories of this century, i. e., the development of hybrid maize by crosses of inbred lines. One of the main applications of anther culture has been to produce diploid homozygous pure lines in a single generation, thus saving many generations of backcrossing to reach homozygosity by traditional means or in crops where self-pollination is not possible. Because doubled haploids are equivalent to inbred lines, their value has been appreciated by plant breeders for decades. The search for natural haploids and methods to induce them has been ongoing since the beginning of the 20th century."

Over the past decade, the use of Renewable Energy Technology (RET) has significantly increased around the globe. Technologies that once were considered experimental are now being deployed on commercial scales at phenomenal rates, delivering cost-effective substitutions for conventional, fossil fuel-based systems that cause problems including greenhouse gas emissions, expensive operating costs, and global pollution. But these new systems come at a costly rate, and because of this, officials must review their overall efficiency and effectiveness. Global Sustainable Development and Renewable Energy Systems pushes through the boundaries of current research to introduce the concept of an energy management information system, exploring the role of energy for sustainable development. This book goes into great detail describing the benefits of these systems for organizations, focusing on corporate sustainability initiatives and activities to combat climate change. Research presented in this publication includes modeling techniques, software applications, and case studies that reveal how renewable energy sources such as wind, solar, and biomass fuel can have a significant implications for both operating costs and environmental impacts.
This book explores the agrarian landscape and economy of the eastern Mediterranean from modern Israel to Turkey. This region experienced a surge in population between the fifth and sixth centuries AD that raised the population to levels often only regained in the late twentieth century. Cities expanded and the eastern lands reached a pinnacle of cultural expression and economic prosperity in the century before the arrival of Islam. Behind all this lay the ability of Roman farmers to feed themselves by producing a reliable surplus of food. Michael Decker describes precisely how this was done: how plants critical to survival were grown and how new plants were introduced. He also catalogues the range of intensive farming methods used and the rise of cash-crop farming based on olive oil and wine that was traded throughout Europe, western Asia, and parts of Africa.
The 18 chapters making up In Vitro Haploid Production in Higher Plants are divided into two sections. Section 1 (eight chapters) covers historical and fundamental aspects of haploidy in crop improvement. Section 2 deals with methods of haploid production, including anther culture, micropore culture, ovary culture, pollination with irradiated pollen, in vitro pollination, and special culture techniques, including polyhaploid production in the Triticeae by sexual hybridization, the influence of ethylene and gelling agents on anther culture, conditional lethal markers, and methods of chromosome doubling.
Using a political-economic approach supplemented with insights from human ecology, this volume analyzes the long-term dynamics of food security and economic growth. The book begins by discussing the nature of preindustrial food crises and the changes that have occurred since the 19th century with the ascent of technical science and the fossil fuel revolution. It explains how these changes improved living standards but that the realization of this improvement was usually dependent on government support for smallholder modernization. The author sets out how the evolution of food security in different regions has been influenced by farm policy choices and how these choices were shaped by local societal characteristics, international relations and changing configurations in metropolitan countries. Separate chapters are devoted to the interaction of this evolution with debates on food security and economic growth and with international economic policies. The final chapters highlight the new challenges for global food security that will arise as traditional sources of biomass production and the more easily extractable reserves of fossil biomass become depleted or can no longer be used. Overall, the book emphasizes the inadequacy of current explanations with regard to these challenges. It explores what is needed to ensure a sustainable future and calls for a rethinking of these issues; a necessary reflection in today's unstable global political situation.
The papers in this volume comprise the refereed proceedings of the First Int- national Conference on Computer and Computing Technologies in Agriculture (CCTA 2007), in Wuyishan, China, 2007. This conference is organized by China Agricultural University, Chinese Society of Agricultural Engineering and the Beijing Society for Information Technology in Agriculture. The purpose of this conference is to facilitate the communication and cooperation between institutions and researchers on theories, methods and implementation of computer science and information technology. By researching information technology development and the - sources integration in rural areas in China, an innovative and effective approach is expected to be explored to promote the technology application to the development of modern agriculture and contribute to the construction of new countryside. The rapid development of information technology has induced substantial changes and impact on the development of China's rural areas. Western thoughts have exerted great impact on studies of Chinese information technology devel- ment and it helps more Chinese and western scholars to expand their studies in this academic and application area. Thus, this conference, with works by many prominent scholars, has covered computer science and technology and information development in China's rural areas; and probed into all the important issues and the newest research topics, such as Agricultural Decision Support System and Expert System, GIS, GPS, RS and Precision Farming, CT applications in Rural Area, Agricultural System Simulation, Evolutionary Computing, etc.
The challenges and opportunities offered to British farming by the
profound changes of the eighteenth and nineteenth centuries make
these years of outstanding interest to the agricultural historian.
These original essays are presented to Gordon Mingay, the most
distinguished historian of the Agricultural Revolution, and reflect
his own interests in three central themes; landownership and landed
society; rural labour; and agriculture both as a business and as a
way of life.
This edited volume summarizes information about the situational context, threats, problems, challenges and solutions for sustainable pastoralism at a global scale. The book has four goals. The first goal is to summarize the information about the history, distribution and patterns of pastoralism and to identify the importance of pastoralism from social, economic and environmental perspectives. The results of an empirical investigation of the environmental and socio-economic implications of pastoralism in representative pastoral regions in the world are also incorporated. The second goal is to argue that breaking coupled human-natural systems of pastoralism leads to degradation of pastoral ecosystems and to create an analysis framework to assess the vulnerability of worldwide pastoralism. Our analysis framework provides approaches to help comprehensively understand the transitions and the impacts of human-natural systems in the pastoral regions in the world. The third goal is to identify the successful models in promoting coupled human-natural systems of pastoralism, and to learn lessons of breaking coupled human-cultural pastoralism systems through examining the representative cases in regions including Central Asia, Southern and Eastern Asia, Northern and Eastern Africa, the European Alps and South America. The fourth goal is to identify the strategies to build the resilience of the coupled human-natural systems of pastoralism worldwide. We hope that our book can facilitate the further examination of sustainable development of coupled human-natural systems of pastoralism by providing the summaries of existing data and information related to the pastoralism development, and by offering a framework for better understanding and analysis of their social, economic and environmental implications.
This book covers the emerging applications of different computational and optimization techniques in order to achieve a sustainable agriculture. A sustainable agricultural management requires tools in providing integrated, area-specifi c, and interpreted prediction or forecasting and guidance in every aspect in agriculture.
Principles of Soil and Plant Water Relations, Third Edition describes the fundamental principles of soil and water relationships in relation to water storage in soil and water uptake by plants. The book explains why it is important to know about soil-plant-water relations, with subsequent chapters providing the definition of all physical units and the SI system and dealing with the structure of water and its special properties. Final sections explain the structure of plants and the mechanisms behind their interrelationships, especially the mechanism of water uptake and water flow within plants and how to assess parameters. All chapters begin with a brief paragraph about why the topic is important and include all formulas necessary to calculate respective parameters. This third edition includes a new chapter on water relations of plants and soils in space as well as textbook problems and answers.
China's agricultural growth in the since the 1970s has been called a miracle. An analysis of the sources of this miraculous growth is the focus of this volume. In addition, this book also investigates the impact of economic reforms on agriculture, the potential of grain production in China, and regional disparities in agricultural production and growth performance. |
