This book analyses the drivers of specific common pool resource problems, particularly in fisheries and forestry, examining the way in which private and public regulation have intervened to fight the common pool resource problem by contributing to the establishment and maintenance of property rights. It focuses on the various forms of regulation that have been put in place to protect fisheries and forestry over the past decades - both from a theoretical as well as from a policy perspective - comparing the concrete interaction of legal and policy instruments in eight separate jurisdictions.

Natural and agro-ecosystems are frequently exposed to natural or synthetic substances, which, while they have no direct nutritional value or significance in metabolism, may negatively affect plant functioning. These, xenobiotics, may originate from both natural (fires, volcano eruptions, soil or rock erosion, biodegradation) and anthropogenic (air and soil pollution, herbicides) sources. And, while affected plants have only a limited number of possibilities for avoiding accumulation of these compounds, they do exhibit several enzymatic reactions for detoxification including oxidation, reduction, hydrolysis and conjugation reactions. In agro-ecosystems in particular these mechanisms have great significance in relation to herbicide detoxification and tolerance. In this volume an international group of experts present an overview of the nature and distribution of organic xenobiotics, including their uptake, effects on plant functioning and detoxification mechanisms. The particular significance of glutathione S-transferases in bio-indication and bio-monitoring, and in the detoxification of volatile organic air pollutants and herbicides is evaluated, and their potential significance in phytoremediation and bioaccumulation will be discussed. This volume will be of interest to a wide audience, from graduate students to senior researchers in a wide range of disciplines including plant ecology, plant biochemistry, agriculture and environmental management. It will also be of practical interest to environmentalists, policy makers and resource managers.

This book describes the sequencing efforts for Neem (Azadirachta indica A. Juss), one of the most versatile tropical evergreen tree species. The neem tree is a source of various natural products, including the potent biopesticide azadirachtin and limonoids, which have a broad spectrum of activity against insect pests and microbial pathogens. To identify genes and pathways in neem, three neem genomes and several transcriptomes are studied using next-generation sequencing technologies. Neem has been extensively used in Ayurveda, Unani and homoeopathic medicine and is often referred to as the 'village pharmacy' by natives due to its wealth of medicinal properties. Besides the description of the genome, this book discusses the neem microbiome and its role in the production of neem metabolites like salanin, nimbin and exopy-azadirachtin under in vitro conditions. It also highlights cell and tissue culture using various neem explants including the leaf, root, shoot, cambium, etc.

This book describes specific, well-know controversies in the genetic modification debate and connects them to deeper philosophical issues in philosophy of technology. It contributes to the current, far-reaching deliberations about the future of food, agriculture and society. Controversies over so-called Genetically Modified Organisms (GMOs) regularly appear in the press. The biotechnology debate has settled into a long-term philosophical dispute. The discussion goes much deeper than the initial empirical questions about whether or not GM food and crops are safe for human consumption or pose environmental harms that dominated news reports. In fact, the implications of this debate extend beyond the sphere of food and agriculture to encompass the general role of science and technology in society. The GM controversy provides an occasion to explore important issues in philosophy of technology. Researchers, teachers and students interested in agricultural biotechnology, philosophy of technology and the future of food and agriculture will find this exploration timely and thought provoking.

The development and use of genetically modified organisms (GMOs) has been a contentious topic for the last three decades. While there have been a number of social science analyses of the issues, this is the first book to assess the role of Non-Governmental Organizations (NGOs) in the debate at such a wide geographic scale. The various positions, for and against GMOs, particularly with regard to transgenic crops, articulated by NGOs in the debate are dissected, classified and juxtaposed to corresponding campaigns. These are discussed in the context of key conceptual paradigms, including nature fundamentalism and the organic movement, post-colonialism, food sovereignty, anti-globalisation, sustainability and feminism. The book also analyses how NGOs interpret the debate and the persuasive communication tactics they use. This provides greater understanding of the complexity of negotiations in the debate and explains its specific features such as its global scope and difficulty in finding compromises. The author assesses the long-term interests of various participants and changes in perceptions of science and in public communication as a result. Examples of major NGOs such as Greenpeace, Oxfam and WWF are included, but the author also provides new research into the role of NGOs in Russia.

In response to low iron availability in the environment most microorganisms synthesize iron chelators, called siderophores. Bacteria and fungi produce a broad range of structurally diverse siderophores, which all show a very high affinity for ferric ions.

"Microbial Siderophores" presents an up-to-date overview of the chemistry, biology and biotechnology of these iron chelators. Following an introduction to the structure, functions and regulation of fungal siderophores, several chapters focus on siderophores of pseudomonads. Here, the technique of siderotyping, which has proved to be a rapid, accurate and inexpensive tool for pseudomonad characterization and identification, is described. Further, the biological significance of siderophores of symbiotic fungi and the possible role of siderophores in pathogenesis are discussed. In addition to methodological approaches, chapters on the biotechnological production of siderophores and their application in promoting human and plant health are included.

Natural saline water, waste water, and irrigation return flow endanger the groundwater aquifers in the Rift. In the long run this will ruin the socio-economic backbone of the settlements in the area. Sustainability of the water resources will only be achieved when the process of water replenishment and its underground flow is understood and water extraction is regionally controlled. Rare earth element and spider patterns are presented as new tools for studying the hydrology. Progress in 3-D modelling of groundwater flow proved successfully the impact of pumping on the surroundings of wells and overexploitation of aquifers.

This textbook presents the concepts and processes involved in the soil-plant-atmosphere system as well as its applications in the water cycle in agriculture. Although reaching the frontier of our knowledge in several subjects, each chapter starts at the graduation level and proceeds to the post-doctoral level. Its more complicated subjects, as math and physics, are well explained, even to readers not well acquainted with these tools. Therefore, it helps students read, understand, and developing their thoughts on these subjects. Instructors also find it an easy book with the needed depth to be adopted in courses related to Soil Physics, Agricultural Management, Environmental Protection, Irrigation and Agrometeorology. It serves also as "lexicon" to engineers and lawyers involved in agricultural, environmental cases.

Haploid plants have the gametophytic number of chromosomes. They are of great importance, especially in studies on the induction of muta tions and also for the production of homozygous plants, they are needed in large numbers. The conventional methods employed by plant breeders for their production are cumbersome, time-consuming, laborious and rather inefficient. Sometimes it may take years to produce a pure line. However, with the introduction of in vitro techniques, especially anther culture for the induction of androgenesis, it has become increasingly evi dent that these methods considerably accelerate the production of haploids for plant breeding programs. During the last decade, in vitro-produced haploids have been incor porated into breeding programs of many agricultural crops, and positive results have been obtained especially with rice, wheat, potato, barley, maize, asparagus, sunflower, brassica, tobacco, etc. Among these, rice and wheat are the best examples in which a number of improved varieties have been released. In wheat, the breeding cycle can be shortened by three or four generations when the pollen haploid breeding method is used instead of conventional cross-breeding. The release of the wheat varieties Jinghua 1 and Florin is a typical example of what can be achieved with other crops. Taking these developments into considera tion, the present volume, Haploids in Crop Improvement I, was compil ed."

Plants use resources, i.e. carbon, nutrients, water and energy, either for growth or to defend themselves from biotic and abiotic stresses. This volume provides a timely understanding of resource allocation and its regulation in plants, linking the molecular with biochemical and physiological-level processes. Ecological scenarios covered include competitors, pathogens, herbivores, mycorrhizae, soil microorganisms, carbon dioxide/ozone regimes, nitrogen and light availabilities. The validity of the Growth-Differentiation Balance Hypothesis is examined and novel theoretical concepts and approaches to modelling plant resource allocation are discussed. The results presented can be applied in plant breeding and engineering, as well as in resource-efficient stand management in agriculture and forestry.

This book is a state-of-the-art review of the physical, chemical and mineralogical properties of anthropogenic soils, their genesis morphology and classification, geocultural setting, and strategies for reclamation, revitalization, use and management.

This book is about climate change and its relation to agriculture and rural livelihoods. It starts by providing a basic understanding of climate change science followed by the relation of climate change to agriculture, the impact of which is discussed based on the particular impact of climate change on plant and animal physiology. The book further discusses the inclusion of the agriculture sector in various international climate change negotiations. It also reviews the cost and opportunities for agricultural projects through international climate change regimes, specifically the Clean Development Mechanism under the Kyoto Protocol. With this background, the book finally proceeds to an explanation of the methodologies used to assess the impact of climate change on agriculture and empirically discusses its impact on agriculture and rural livelihoods in Nepal.

In conventional views, pastoralism was classified as a stage of civilization that needed to be abolished and transcended in order to reach a higher level of development. In this context, global approaches to modernize a rural society have been ubiquitous phenomena independent of ideological contexts. The 20th century experienced a variety of concepts to settle mobile groups and to transfer their lifestyles to modern perceptions. Permanent settlements are the vivid expression of an ideology-driven approach. Modernization theory captured all walks of life and tried to optimize breeding techniques, pasture utilization, transport and processing concepts. New insights into other aspects of pastoralism such as its role as an adaptive strategy to use marginal resources in remote locations with difficult access could only be understood as a critique of capitalist and communist concepts of modernization. In recent years a renaissance of modernization theory-led development activities can be observed. Higher inputs from external funding, fencing of pastures and settlement of pastoralists in new townships are the vivid expression of 'modern' pastoralism in urban contexts. The new modernization programme incorporates resettlement and transformation of lifestyles as to be justified by environmental pressure in order to reduce degradation in the age of climate change.

This volume summarizes recent technological advances in the design and engineering of Solanaceae and Cucurbitaceae crops. It begins with contributions on the tomato and melon genome sequence, databases for Solanaceae and Cucurbitaceae research, DNA markers in the breeding of the two families, and mutant resources and TILLING platforms in tomato research. Subsequent chapters address the use of molecular techniques for the modification of important breeding traits, such as tomato fruit set, growth, ripening, and sugar accumulation, as well as disease and insect resistance in melons. The volume closes with chapters on genome editing using artificial nucleases as a future breeding tool, and on the development of an in silico crop design system. It offers a valuable resource for plant breeders, molecular biologists, and agronomists.

This thoughtful and provocative book provides a concise, up-to-date presentation of how current and projected future phosphorus scarcity will affect legume growth and their symbiotic nitrogen-fixing capabilities. It is a timely examination of the physiological and molecular responses of nodules to phosphorous deficiency in attempt to identify common principles. Students and researchers in the many disciplines related to crop productivity will find this title an exciting contribution in the area of plant stress physiology. The knowledge in this volume can also aid plant breeders, particularly through new methods of genetic engineering, in developing unique and adaptive cultivars with higher symbiotic efficiency. The awareness of the rapidly rising world population must translate into a parallel increase in agricultural production in order to sustain the growing population both now and in the future. Hence, the demand for food crops to produce proteins and vegetable oil for human consumption is going to increase considerably during the coming years. The essential role of legumes in agriculture is well-recognized, given the abundant levels of proteins and oils found in plants along with their enormous contribution to the sustainability of agricultural systems and human health. The capacity of legumes to fix nitrogen (N2) in partnership with rhizobia provides an input-saving and resource-conserving alternative, thereby reducing the need for chemical fertilizers while enhancing overall crop productivity. The use of N2-fixing legumes to produce plant proteins results in a substantial decrease in the consumption of fossil fuels and therefore also in the agricultural effects to global warming. However, a major constraint to legume production is low soil phosphorus (P) availability, considering that an overwhelming majority of the world's soils are classified as P-deficient. Low-P availability is especially problematic for legumes, since legume nodules responsible for N2 fixation have a high P requirement. Therefore, this book explains how nodule N2 fixation responds to low P availability, which is crucial for improving legume production and maintaining agricultural sustainability in the context of the global P crisis.

Within the context of the Convention on Biological Diversity (CBD), the Cartagena Protocol on Biosafety (CPB) was established as an implementing agreement. The CPB is an international agreement establishing the rights of recipient countries to be notified of and to approve or reject the domestic import and/or production of living modified organisms (LMOs). Decisions regarding import/production are to be on the basis of a biosafety assessment. Article 26.1 of the CPB allows for the (optional) inclusion of socio-economic considerations (SECs) into that biosafety assessment process. This book compiles expert assessments of the issues relevant to SEC assessment of LMOs and fundamental for decisions regarding whether to undertake such assessments at all. It includes an overview of the inclusion of SEC assessment in the regulation of LMOs that looks at the rationale for the inclusion of SECs, in the context of the existing science-based risk assessment systems. This book reviews the various factors that can and have been suggested for inclusion in SEC assessment, and provides a meaningful dialogue about the contrasts, benefits and tradeoffs that are, and will, be created by the potential move to the inclusion of SECs in the regulation of LMOs, making it of interest to bothacademics and policy-makers."

The future of agriculture greatly depends on our ability to enhance productivity without sacrificing long-term production potential. The application of microorganisms, such as the diverse bacterial species of plant growth promoting rhizobacteria (PGPR), represents an ecologically and economically sustainable strategy. The use of these bio-resources for the enhancement of crop productivity is gaining importance worldwide. Bacteria in Agrobiology: Crop Productivity focus on the role of beneficial bacteria in crop growth, increased nutrient uptake and mobilization, and defense against phytopathogens. Diverse group of agricultural crops and medicinal plants are described as well as PGPR-mediated bioremediation leading to food security.

Agricultural research is one of the most widespread forms of organized research in the world, in both developed and developing countries. Management of agricultural research involves many decisions that have scientific, social and political consequences. Every country has established agricultural research priorities based on many complex factors that must be considered when decisions are made on the choice of research problems to be investigated. Resources must be divided among projects that often compete for the limited funding available that supports the total research enterprise. This book will provide those individuals who manage research with methods and procedures that can be used in their management organization.

This book describes the latest advances in Allium genome research. Allium includes plant species known for their huge nuclear genome size, which makes them ideal for somatic chromosome observations in high school experiments. In order to advance the genome analysis of A. cepa and its functional study, scientists in international research collaborations have developed several types of artificially manipulated genetic stocks and analyzed them using modern technologies. The Allium vegetable crop includes garlic, shallot, wakegi onion, Japanese bunching onion, and rakkyo. Bulb onion is one of the world's most important Allium commercial crops, with an estimated annual production of 85.8 million tons in 2013, and ranking third after tomato and watermelon in terms of global vegetable crops.

The chapter summarizes the pathogenesis of BCO and reviews the efficacy of probiotics as a prophylactic treatment. The third chapter discusses bone health in laying hens. It reviews bone development, keel and other bone health problems and factors contributing to poor bone health. It also summarises key strategies for improving bone health, including breeding, nutrition, rearing practices and housing. The final chapter assesses the problem of lameness in intensively-reared broiler flocks. The chapter also discusses skin health in broilers. It summarises key risk factors as well as ways of monitoring and reducing the problem, from breeding programmes and enrichment to sequential feeding regimes.

This volume is the first ever English translation of Part III of Johann von Thunen's famous 'Isolated State'. The original German publication from 1863 has been translated by Keith Tribe and is E Ulrich van Suntum on behalf of the Thunen Society. It deals with the optimum rotation period of woods, a central problem of capital theory, which has been studied by many famous economists. Debates on this issue have still not reached a final conclusion, and therefore Thunen's early approach to sustainable forestry is of central importance. Thunen has been hailed an innovator way ahead of his time. This book celebrates his ideas as an economist, as a farmer and a thinker on agrarian policy, and endeavoursto revive the study and discussion of forestry economics and its history.

This book shows how the use of biodegradable plastics in agriculture can have a profound positive impact on plasticulture. Starting with an organic chemistry approach to biodegradable and compostable plastics, both natural and synthetic, it then analyzes the technological and agronomic aspects of existing bioplastics for protected cultivation (mulching, direct cover, low tunnels). It describes the new sprayable biodegradable mulching method, which is based on the use of waterborne polysaccharides and cellulosic fibers. A further chapter describes the research and technology of biodegradable plastics for different agricultural practices. It also includes chapters on life cycle assessment (LCA) of biodegradable plastics for agriculture, and existing and developing standards in the field. It is a valuable resource for agronomists, chemical and materials engineers, polymer technologists and scientists, as well as for a more general readership interested in the application of green chemistry principles to the vast world of crop production.
