Genome editing is rapidly transforming plant research. The technique offers unparalleled precision in breeding without the need to introduce foreign DNA into plants. CRISPR/Cas systems have established themselves as the leading technique in genome editing. Genome editing for precision crop breeding takes stock of the wealth of research on these techniques and their potential in crop breeding. Chapters in this volume review advances in techniques such as TALENS and zinc finger nucleases, double-strand break repair techniques, insertion-based genome edits, base editing, guide RNAs and gRNA/Cas9 constructs. This collection also surveys applications of gene editing in improving key traits in key cereal crops including barley, maize and sorghum as well as brassicas, tomatoes and perennials. With its distinguished editor and international team of expert authors, Genome editing for precision crop breeding will be a standard reference for university and other researchers involved in crop breeding, government and other agencies involved in regulating advances in crop breeding (such as genetic modification), crop breeding companies and farmers interested in the latest breeding techniques.

This book examines global environmental governance and how legal, institutional, and conceptual reform can facilitate a transformation to a new 'natural-systems' form of agriculture. Profound global climate disruption makes it essential that we replace our current agricultural system - described in this book as a fossil-carbon-dependent 'modern extractive agriculture' - with a natural-systems agriculture featuring perennial grains growing in polycultures, thereby mimicking the natural grassland and forest ecosystems that modern extractive agriculture has largely destroyed. After examining relevant international legal and conceptual foundations (sovereignty, federalism, global governance) and existing international organizations focusing on agriculture, the book explores legal and institutional opportunities to facilitate dramatic agricultural reform and ecological restoration. Among other things, it explains how innovative federalism structures around the world provide patterns for reorienting global environmental governance, including what the book calls eco-states that would, through exercise of pluralistic sovereignty, be responsible for agroecological management. Drawing from his experience working in international institutions, the author provides detailed global-governance proposals for facilitating the type of agricultural reform that can help avoid ecological collapse, especially through soil degradation and climate change. This book will be of great interest to students and scholars of international law, agroecology, climate change, ecological restoration, sustainable development, and global governance, as well as policy-makers and practitioners working in these fields.

Spices provide our food with nutraceutical value rather than actual nutrition. But apart from the popular and major spices, there are several other spices, which, in spite of their enormous contribution to human health, remain underexploited or underutilized. This new volume, Underexploited Spice Crops: Present Status, Agrotechnology, and Future Research Directions, is a valuable compilation of agrotechniques coupled with background information, research works, and scientific discussions on these spices. It will include in-depth narration on underexploited spice crops as products in influencing present-day the global export market and the renewed interest in these crops throughout the world. The volume deals with the scientific approach of growing underexploited spices with the intention of popularizing them. Separate chapters on the importance of each spice, methods of growing and harvesting, and recent research from around the world along with future strategies are covered.

The first chapter reviews evidence of the human health impact of wheat flour fortification and how it is measured and studied. The chapter explores the benefits to wheat flour fortification, citing the process's ability to address widespread health problems caused by nutrient deficiencies, such as iron deficiency and anaemia. The second chapter examines the biofortification of maize with Provitamin A carotenoids and its potential in improving micronutrient intake for the population of food insecure people. The chapter refers to the Zambia maize biofortification programme as a case study to demonstrate this. The third chapter similarly considers the rising threat of micronutrient malnutrition, but highlights the integral role biofortified legume crops have in offsetting this. The chapter reviews the genetic variability of iron and zinc content in many legume crops, and shows how this is being used to guide breeding efforts through both transgenic approaches and agronomic management. The final chapter assesses the problem of vitamin A deficiency in countries where cassava is considered a key crop and consumed as a main food source. The chapter reviews the HarvestPlus breeding programme for increasing the nutrient density of cassava, as well as strategies that can be implemented to promote the use of pro-vitamin A varieties by farmers and consumers.

The final chapter addresses the critical safety issue of mycotoxin contamination of food waste planned for re-use. It reviews factors affecting mycotoxin growth and the particular problem of masked mycotoxins.

In recent decades, the governance of the environment in agri-food systems has emerged as a crucial challenge. A multiplicity of actors have been enrolled in this process, with the private sector and civil society progressively becoming key components in a global context often described as neoliberalization. Agri-environmental governance (AEG) thus gathers a highly complex assemblage of actors and instruments, with multiple interrelations. This book addresses this complexity, challenging traditional modes of research and explanation in social science and agri-food studies. To do so, it draws on multiple theoretical and methodological insights, applied to case studies from Asia, Europe, Africa, and the Americas. It elaborates an emergent approach to AEG practices as assemblages, looking at the coming-together of multiple actors with diverse trajectories and objectives. The book lays the foundations for an encompassing theoretical framework that transcends pre-existing categories, as well as promoting innovative methodologies, which integrate the role of social actors - including scientists - in the construction of new assemblages. The chapters define, first, the multiplicities and agencies inherent to AEG assemblages. A second set tackles the question of the politics in AEG assemblages, where political hierarchies interweave with economic power and the search for more democratic and participative approaches. Finally, these insights are developed in the form of assemblage practice and methodology. The book challenges social scientists to confront the shortcomings of existing approaches and consider alternative answers to questions about environmental governance of agri-food systems.

"It is likely that Plant genetic resources will become the essential methods manual to facilitate their international exchange and local dissemination. It may well become the standard reference for researchers at universities, institutes, government departments and plant nurseries for many years. It provides an indispensable contribution as a handbook for plant collectors." (Plant Science Bulletin - Botanical Society of America) Maintaining and benefitting from plant genetic diversity are key challenges facing agriculture. Challenges include a narrowing genetic base for many key crops, the loss of landraces and wild varieties with agricultural intensification and urbanisation, and the need to develop the role of existing gene banks from repository of genetic diversity to enablers of the flow of germplasm and genetic information for breeding more robust varieties. Plant genetic resources: A review of current research and future needs surveys the wealth of research addressing these challenges and the opportunity for a more integrated, global approach to protecting and leveraging plant genetic diversity for a more sustainable agriculture. The book assesses ways of valuing and monitoring plant genetic diversity and discusses advances in in-situ and ex-situ strategies for conserving plant genetic diversity. The book concludes by reviewing ways of enhancing the use of plant genetic diversity, including participatory plant breeding programmes and more effective seed systems. With its eminent editor and range of international expertise, Plant genetic resources: A review of current research and future needs will be a standard reference for university and other researchers studying crop genetic resources and breeding, staff managing genebanks and germplasm collections, government and other agencies regulating the collection, storage and exchange of germplasm, as well as companies involved in crop breeding.

The third chapter illustrates how crop models account for the interactions between soil, genotypes, management, and climate, on crops grown in various rotations, and their effects on yield and environmental outcomes under current and future climate scenarios. The fourth chapter assesses the potential of decision support systems for crop rotations in improving soil health and agricultural sustainability. The final chapter reviews how crop rotations with non-cereal species can be implemented to substantially reduce inoculum sources for residue-borne cereal leaf diseases.

This collection features four peer-reviewed literature reviews on cover crops in agriculture. The first chapter describes the contribution of cover crops to improving soil health. The chapter reviews their key role e.g. supplying a food source for soil organisms, providing a source of carbon to help build soil organic matter, enhancing nutrient dynamics in the soil and improving soil structure. The second chapter considers recent research on the benefits of cover crops in organic cultivation in areas such as soil structure and erosion control as well as nutrient cycling. It also looks at the wider role of cover crops in control of weeds, diseases and pests, promoting biodiversity and reducing greenhouse gases (GHGs). The third chapter highlights the use of different cover crops species to promote live or dead soil mulch cover in Conservation Agriculture systems. It also reviews how cover crops effect aspects such as soil acidity and nutrient availability, soil physical and biological properties, soil nematode control, weed control and grain yield. The final chapter reviews the role of cover crops in weed control. Cover crops are important additions to crop rotations because they suppress weeds during rotational periods when crops are absent and provide ecosystem services that enhance soil quality and fertility.

It also reviews genomic resources that can facilitate a better understanding of phenotype-genotype associations and formulate genomic-assisted breeding strategies. The final chapter addresses the polygenic nature of tolerance to drought and to heat in grain legumes. It reviews advances in understanding plant adaptation to stress, the assembly of molecular and phenotyping tools to support breeding and the development of tolerance through traditional and molecular breeding techniques.

High yields and environmental control in crop farming call for precise adaptations to local growing conditions. Treating large fields in a uniform way by high capacity machinery cannot be regarded as a sustainable method for many situations. Because differences existing within single fields must be considered. The transition from former field work carried out manually or by small implements to present-day high-capacity machinery caused that the farmers lost the immediate and close contact with soils and crops. However, modern sensing and controlling technology can make up for this deficit. High tech methods that include proximal sensing and signals from satellites can provide for controls that allow adjusting farming operations to small fractions of one ha and sometimes even down to some m2, hence in a site-specific mode. This applies to operations for soil cultivation, sowing, fertilizing and plant protection. This book deals with site-specific concepts, applications and results.

Cinnamon is the common name for the spice obtained from the dried inner bark of several species of the genus Cinnamomum in the Lauraceae family. In world trade, Cinnamomum cassia (L.) J. Presl Cinnamomum burmannii dominate, but it is of a different quality to 'true' or 'Ceylon' cinnamon produced from Cinnamomum zeylanicum Blume (C. verum J. Presl), with the latter much easier to process, giving a more delicate, sweeter flavor with nuances of clove, but more importantly with only traces (often below detection thresholds) of coumarin, compared with 5-7 g/kg in other species. Cinnamon has been a popular and expensive spice in many civilizations, including ancient Egypt, Rome and in 14th and 15th century Europe, where it was used primarily to preserve meat for its antibacterial properties, fine aroma and flavor. Ancient Egyptians used cinnamon in mummification process due to its antibacterial properties and fragrance. The quest for cinnamon brought many explorers to Ceylon, whose ancient history is intertwined with the cinnamon trade. Ancient Egyptians and Romans used cinnamon as a valued spice and as an incense. In recent years, much research has been conducted in crop improvement, processing and value addition in cinnamon. In addition to direct use as a condiment/spice, cinnamon has found a multitude of uses in the food and beverage, traditional medicine, pharmacology, nutraceutical and cosmetics industries. Ceylon cinnamon is unique in that oils distilled from the bark (major constituents are cinnamaldehyde and oleoresins), leaf (eugenol is the major constituent used in dentistry, perfumes, flavorings and as an antioxidant) and roots (camphor) have different industrial uses. Cinnamaldehyde is now a proven natural bactericide widely used in food and beverage industry, effective against Salmonella spp. and Escherichia coli. Thus, it has become an important natural component of organic fruit and vegetable juices to enhance microbial safety of these nutritious beverages. Because of its manifold uses, cinnamon is an important crop. There have been many recent publications on its ethnobotany, genetics, crop improvement, agronomy, processing, biotechnology, chemistry, food and medicinal uses, and industrial applications. However, one book condensing all these findings is lacking. Our publication, with chapters devoted to all these aspects of cinnamon written by experts in these fields, condenses current knowledge into a single source and contribute to the advancement and dissemination of knowledge and technology. Contributors to the book constitute internationally renowned senior scientists and academics with hands-on experience as well as movers and shakers of industry, thereby striking a right balance between theory and practice. Therefore it is a valuable source for students, teachers, scientists, planners policy makers, practicing agriculturists and industrialists, and a prized acquisition to any library in higher education institutions, R & D institutions and public and private sector institutions in agriculture and allied fields.

"The sustainable intensification of smallholder farming systems is a standard reference on how best to target support for smallholders to achieve real improvements in their livelihoods." (IITA - Cassava Matters) Due to a lack of understanding of the constraints they face, many projects developed to support smallholders fail with low adoption rates and limited improvements in livelihoods and food security. Greater emphasis must be placed upon successfully supporting smallholder farmers and their farming systems. The sustainable intensification of smallholder farming systems provides a comprehensive review of recent research on effective support measures to improve the livelihoods of smallholders in sub-Saharan Africa. This collection features detailed discussions on ways to improve access to key resources, such as seeds, tools and expertise for soil health improvement and integrated pest management (IPM) programmes. A part dedicated to finance and information assesses the need to improve support systems, including farmer organisations and commercial extension services, for the benefit of particular groups of smallholders, e.g. female farmers. Based on a wealth of practical experience from leading experts in the field, The sustainable intensification of smallholder farming systems will be a standard reference on how best to target support for smallholders to achieve real improvements in their livelihoods. It will be essential reading for university and other researchers studying smallholder farming systems in departments of agricultural science, international development, politics and development economics. It will also be a key reference for government and non-governmental organisations (NGOs) involved in development programmes focussing on smallholders, particularly in sub-Saharan Africa.

There is an ever-increasing demand for more food but one of the stumbling blocks to achieving this goal is quality and quantity losses due to various pests and pathogens and the mycotoxins synthesized by these harmful biotic entities. Thus far, strategies employed to manage these post-harvest diseases and mycotoxins decontamination include established physical, cultural, and chemical methods. Recently, the application of chemicals to reduce decay and deterioration caused by various pathogens has been impeded as these hazardous chemicals contaminate the environment, enter the food chain, and destroy beneficial microorganisms and pests by aiming at non-target microorganisms. In light of this, the usage of eco-friendly and non-polluting alternatives to chemical pesticides is the call of the hour. Bio-management of Postharvest Diseases and Mycotoxigenic Fungi deals with the current state and future prospects of using various bio-management techniques that are natural, eco-friendly, and environmentally safe. It aims to increase awareness of their potential as well as sensitizing readers to the various aspects of biologicals in pest control. Key Features: Highlights classical versus new techniques adopted to manage postharvest diseases Discusses novel approaches in managing fungal spoilage and mycotoxin decontamination Provides readers with a 360-degree perspective of the pre- and post-harvest quality mycotoxin decontamination research being conducted Details proposals of new ideas to ensure a food secure and pesticide-free world This book disseminates notable and diversified scientific work carried out by leading experts in their own field. Written by qualified scientists in each of their respective disciplines, it can serve as a current and comprehensive treatise on the emerging field of bio-management of postharvest diseases and mycotoxin decontamination by products that are "generally regarded as safe."

In describing the control for each crop, we try to provide you with some information to aid your understanding of both the specific problem and its relation to other crops and pests. Through this understanding, the first stage in the intelligent application of control procedures is achieved. Thus, an over application of pesticides to overcome the.effect of unknowingly harboring a pest reservoir in or at the edge of the field/yard can be avoided. The second stage of intelligent (safe, economic) pest control is gained through thorough familiarity with the use of the chosen method of pest control. The effort expended by academic, industrial, and governmental experts in determining the best dosage levels and methods of application is wasted unless the product label is read and followed. Your interest, hopefully aroused by our work, can be further developed by contacting the appropriate experts in government, academia, or industry. To aid you in this activity, we try to provide references in each section. Finally, this effort is dedicated, with yours, to the production and consumption of agricultural products of the best quality.
