This study, based on a literature review and simulations, shows the efficiency of cover crops at catching nitrate in most agriculture situations. It also analyzes both the negative impacts they can have and the ecosystem services they can provide. The introduction of a cover crop between two main crops helps catch the soil mineral nitrogen before the period of drainage and consequently reduces nitrate leaching and nitrate concentration in the drainage water. This study allows quantifying the efficiency of cover crops at catching nitrate and optimizing their implantation conditions over a large range of French pedoclimatic conditions. The presence of high nitrate levels in surface and ground waters, due to excessive nitrogen fertilization and natural production of nitrate by soil organic matter mineralization, is a double challenge for public health and environment protection.
This book presents conceptual and empirical discussions of adaptation to climate change/variability in West Africa. Highlighting different countries' experiences in adaptation by different socio-economic groups and efforts at building their adaptive capacity, it offers readers a holistic understanding of adaptation on the basis of contextual and generic sources of adaptive capacity. Focusing on adaptation to climate change/variability is critical because the developmental challenges West Africa faces are increasingly intertwined with its climate history. Today, climate change is a major developmental issue for agrarian rural communities with high percentages of the population earning a living directly or indirectly from the natural environment. This makes them highly vulnerable to climate-driven ecological change, in addition to threats in the broader political economic context. It is imperative that rural people adapt to climate change, but their ability to successfully do so may be limited by competing risks and vulnerabilities. As such, elucidating those vulnerabilities and sources of strength with regard to the adaptive capacities needed to support successful adaptation and avoid maladaptation is critical for future policy formulation. Though the empirical discussion is geographically based on West Africa, its applicability in terms of the processes, structures, needs, strategies, and recommendations for policy transcends the region and provides useful lessons for understanding adaptation broadly in the developing world.

Increase in world population, extreme weather conditions, decrease in fresh water supplies, and changes of dietary habits are major issues that affect global food security. We are expected to face the challenges of land use by 2050 because population will reach 9 billion while agricultural productivity losses are expected due to overuse of lands. How can we feed the next generations in a manner that respects our finite natural resources? Managing our resources in a sustainable way have only begun for selected crops. Much remains to be done to increase food yield. Cropping practices capable of sustainable production need to be elaborated, especially in fragile ecosystems. Typical applications will include the improvement and use of genetic resources; crop management and diversification; diffusion of improved varieties; development of cropping systems; sustainable cropping systems for areas prone to environmental degradation; use of agro-ecological data for crop production forecasting; and networks for regional coordination, and data exchange. The impetus behind this book is to bring attention to a cropping system that bears direct relevance to sustainable agriculture and food security. "Underutilized" crops are found in numerous agricultural ecosystems and often survive mainly in marginal areas. It is timely to review their status because, in recent decades, scientific and economic interests have emerged which focus on lesser-known cultivated species. Underutilized crops have a great potential to alleviate hunger directly, through increasing food production in challenging environments where major crops are severely limited. "Global Perspectives on Underutilized Crops" is therefore topical and highlights the unmet agricultural challenges that we face today. This book is an important resource for students and researchers of crop science and agricultural policy makers.
Evolution gave rise to a prominent insect diversity at every level of ecological niche. Since then, hordes of insects have threatened human and cattle health as well as most of all green lands and agricultural crops. Now, the insect problem expands from many mutant forms of yellow dengue fever mosquitoes to highly-resistant larvae of most all various phytophageous species. The tremendous expansion of insects is due not only to an increasing resistance capacity to insecticides, but also to a strong capacity for adapting to different climate and environmental changes, including global warming. Obviously insects display a number of rudimentary systems to build an extremely efficient organism to survive in a changing world. In many species, one pheromone molecule is enough to trigger mating behavior. Therefore, insects have become crucial models not only for evolutionary studies, but also for understanding specific mechanisms underlying sensory-based behaviors. Most of insect species such as ants, beetles, cockroaches, locusts, moths and mosquitoes largely rely on olfactory cues to explore the environment and find con-specifics or food sources. A conglomerate of renowned international scientific experts is gathered to expose the insect problem on the various continents of the planet and propose an alternative to the use of toxic insecticides. Sex pheromones, specific chemical signals necessary for reproduction, and pheromone detection in insects are described with full details of the olfactory mechanisms in the antennae and higher centers in the brain. Thus, new synthetic pheromones and/or plant odors with specific molecular target sites in the insect olfactory system are proposed for sustainable development in agricultural and entomological industries. Disrupting insect pheromone channels and plant odor detection mechanisms is solemnly envisioned as a unique way to control invasive insect pest species while preserving human and environment safety.
This book explains in depth the issues and challenges faced by rice farmers in India in relation to production and productivity, and the possible adaptation strategies to climate change. Based on five years of groundbreaking research on emerging trends in cultivation in major rice growing regions in India, it begins by describing production and yield trends across different rice growing regions. It then offers a comprehensive review of relevant literature and the quantification methodologies and approaches used to analyze the impact of climate change. The book also analyzes climate change impacts on rice productivity and production, applying field-tested quantification methods, such as the Just-Pope production function where time series and cross-section data are simultaneously used for all regions. The results are presented for five geographical regions of India - northern, eastern, western, central and southern - for better comparison and readability. The analyses cover scenarios for both mid-century (2021-2050) and end-century (2071-2100), and in the context of climate change, they also incorporate both medium and high carbon emission scenarios. Thus the future rice production and productivity trends are clearly projected for making necessary interventions. Lastly, the book outlines the essentials of an enabling environment policy and discusses the institutional and policy options necessary to ensure sustainable rice production in India. It also makes the case for introducing appropriate and affordable adaptation strategies to support farmers in different rice-growing regions. The cost-benefit analysis of strategies presented in this book provides an invaluable tool for officials at agriculture departments planning up-scaling of agricultural productivity. The projections are also useful for policy makers and planners developing future investment plans to support rice production in their country. Overall, this book is of interest to a wide audience, including professionals and business enterprises dealing with rice, as well as to academic researchers and students.

This book provides standards and guidelines for quantifying greenhouse gas emissions and removals in smallholder agricultural systems and comparing options for climate change mitigation based on emission reductions and livelihood trade-offs. Globally, agriculture is directly responsible for about 11% of annual greenhouse gas (GHG) emissions and induces an additional 17% through land use change, mostly in developing countries. Farms in the developing countries of sub-Saharan Africa and Asia are predominately managed by smallholders, with 80% of land holdings smaller than ten hectares. However, little to no information exists on greenhouse gas emissions and mitigation potentials in smallholder agriculture. Greenhouse gas measurements in agriculture are expensive, time consuming, and error prone, challenges only exacerbated by the heterogeneity of smallholder systems and landscapes. Concerns over methodological rigor, measurement costs, and the diversity of approaches, coupled with the demand for robust information suggest it is germane for the scientific community to establish standards of measurements for quantifying GHG emissions from smallholder agriculture. Standard guidelines for use by scientists, development organizations will help generate reliable data on emissions baselines and allow rigorous comparisons of mitigation options. The guidelines described in this book, developed by the CGIAR Research Program on Climate Change, Agriculture, and Food Security (CCAFS) and partners, are intended to inform anyone conducting field measurements of agricultural greenhouse gas sources and sinks, especially to develop IPCC Tier 2 emission factors or to compare mitigation options in smallholder systems.
Rice is a vitally important staple food for almost half of the world's population. As the global population increases, the demands for rice are expected to remain high. Since the rice industry will remain sustainable for a long time, the production of rice by-products will remain high. Substantial evidence suggests that rice by-products such as rice husk, rice straw, broken rice, rice germ, rice bran, and brewers' rice may possess beneficial effects against oxidative stress and metabolic disorders. These beneficial effects have been linked to the phytochemicals present in rice by-products such as vitamin E, dietary fiber, -oryzanol, -aminobutyric acid (GABA), and phytosterols. Despite this evidence, the literature pertaining to rice by-products and its derived components has not well been compiled. To this end, Rice By-products: Phytochemicals and Food Products Application provides full coverage of issues pertaining to rice by-products, namely rice demands and rice by-products production, phytonutrients and antioxidant properties of rice by-products, potential health benefits, application in food products, and future prospects. By summarizing all the information in a lucid and comprehensive manner, authors provide a cohesive representation of the literature on the molecular mechanisms involved in the pharmacological effects of the bioactive components that present in rice by-products, as well as plausible means for the prevention of metabolic disorders for readers and allied stakeholders.
Recent advances in genetic engineering and in the chemistry and biochemistry of fruit and vegetables have radically changed our understanding of the mechanisms underlying these processes, and the potential for modification of the products themselves. This is the first book to examine these topics and address the role of fresh fruits and vegetables in a healthy diet and the prevention of cancer and coronary diseases. The main focus is on the secondary metabolites which are responsible for quality characteristics including color, aroma, and flavor, and their nutritional importance and role in the prevention of cancer and cardiovascular diseases. The book also explores how the post-harvest technological treatments to which these commodities are submitted can cause changes in secondary metabolism, with consequences for the quality of the product.
This book focuses on fluxes of energy, carbon dioxide and matter in and above a Central European spruce forest. The transition from a forest affected by acid rain into a heterogeneous forest occurred as a result of wind throw, bark beetles and climate change. Scientific results obtained over the last 20 years at the FLUXNET site DE-Bay (Waldstein-Weidenbrunnen) are shown together with methods developed at the site, including the application of footprint models for data-quality analysis, the coupling between the trunk space and the atmosphere, the importance of the Damkoehler number for trace gas studies, and the turbulent conditions at a forest edge. In addition to the many experimental studies, the book also applies model studies such as higher-order closure models, Large-Eddy Simulations, and runoff models for the catchment and compares them with the experimental data. Moreover, by highlighting processes in the atmosphere it offers insights into the functioning of the ecosystem as a whole. It is of interest to ecologists, micrometeorologists and ecosystem modelers.

This book, which is the first to be published in the emerging field of farm-level microsimulation, highlights the different methodological components of microsimulation modelling: hypothetical, static, dynamic, behavioural, spatial and macro-micro. The author applies various microsimulation-based methodological tools to farms in a consistent manner and, supported by a set of Stata codes, undertakes analysis of a wide range of farming systems from OECD countries. To these case studies, O'Donoghue incorporates farming policies such as CAP income support payments, agri-environmental schemes, forestry planting incentives and biomass incentives - in doing so, he illuminates the merits of microsimulation in this environment.
The food industry is now entering a transition age, as scientific advancements and technological innovations restructure what people eat and how people think about food. Food Tech Transitions provides a critical analysis of food technology and its impact, including the disruption potential of production and consumption logic, nutrition patterns, agronomic practices, and the human, environmental and animal ethics that are associated with technological change. This book is designed to integrate knowledge about food technology within the social sciences and a wider social perspective. Starting with an overview of the technological and ecological changes currently shaping the food industry and society at large, authors tackle recent advancements in food processing, preserving, distributing and meal creation through the lens of wider social issues. Section 1 provides an overview of the changes in the industry and its (often uneven) advancements, as well as related social, ecological and political issues. Section 2 addresses the more subtle sociological questions around production and consumption through case-studies. Section 3 embraces a more agronomic and wider agricultural perspective, questioning the suitability and adaptation of existing plants and resources for novel food technologies. Section 4 investigates nutrition-related issues stemming from altered dietary patterns. Finally, Section 5 addresses ethical questions related to food technology and the sustainability imperative in its tripartite form (social, environmental and economic). The editors have designed the book as an interdisciplinary tool for academics and policymakers working in the food sciences and agronomy, as well as other related disciplines.
This book presents a game changing technology of lower energy-intensive urea production of urea which is used as fertilizer. The technology, from a resource to a knowledge-intensive based industry, investigates a new synthesis approach employing electromagnetic induction and nano-catalyst at lower energy consumption. This clean and green method for a sustainable future might change the landscape of future chemical processes. It is made possible due to the enhancement in nanotechnology where quantum mechanical understanding is called into play. New reactor designs are elaborated on and discussed explicitly. Hematite and nickel oxide nanocatalysts are proposed for the green urea synthesis process, in the presence of static and oscillating magnetic fields. Strategies to increase single to triplet conversion rate are given for better understanding of the improved urea rate. The focus is deliberately on scrutinizing the greenhouse gas effect on the urea yield, in this case CO2 flow rate. Coating techniques for slow release strategies are provided to reduce the volatilization of ammonia and leaching effect, hence offering a complete solution of Green Technology. Agriculture 4.0 that creates the new patterns and precision monitoring of crop rotation and livestock utilization will be able to pave the way for better crop yield. Development of advanced technology in agriculture is important for the implementation of Agriculture 4.0 and currently an inevitable trend of the socioeconomic development in the context of broader international integration for the sustainable future. The author would like to acknowledge Ministry of Higher Education (MOHE) for the grant worth RM 12 million to accomplish Green and Economical Urea project and to have full understanding on Green Technology in Urea. This book is a collaborative effort by her colleagues, Ku Zilati, Khanif, Shahrina, Zainovia, Azizah, Zakaria, and who have carried out the research over the past five years which started in 2011. Their unconditional commitment had brought us together and we completed the project with success. I wish to also thank Dr Menaka Ganeson and all my PhD students, Dr. Saima, Dr. Bilal, Mr. Zia and Mr. Irfan for their commitment to assist me to complete the book. Last but not least, thank you very much to Professor Mike Payne (Cambridge University) and Professor Koziol (Cranfield University) for the comments.
The threat of climate displacement looms large over a growing number of countries. Based on the more than six years of work by Displacement Solutions in ten climate-affected countries, academic work on displacement and climate adaptation, and the country-level efforts of civil society groups in several frontline countries, this report explores the key contention that land will be at the core of any major strategy aimed at preventing and resolving climate displacement. This innovative and timely volume coordinated and edited by the Founder of Displacement Solutions, Scott Leckie, examines a range of legal, policy and practical issues relating to the role of land in actively addressing the displacement consequences of climate change. It reveals the inevitable truth that climate displacement is already underway and being tackled in countries such as Bangladesh, Kiribati, Papua New Guinea, Solomon Islands, Tuvalu and the United States, and proposes a series of possible land solution tools that can be employed to protect the rights of people and communities everywhere should they be forced to flee the places they call home.
This book comprehensively introduces all aspects of the physiology, stress responses and tolerance to abiotic stresses of the Fabaceae plants. Different plant families have been providing food, fodder, fuel, medicine and other basic needs for the human and animal since the ancient time. Among the plant families Fabaceae have special importance for their agri-horticultural importance and multifarious uses apart from the basic needs. Interest in the response of Fabaceae plants toward abiotic stresses is growing considering the economic importance and the special adaptive mechanisms. Recent advances and developments in molecular and biotechnological tools has contributed to ease and wider this mission. This book provides up-to-date findings that will be of greater use for the students and researchers, particularly Plant Physiologists, Environmental Scientists, Biotechnologists, Botanists, Food Scientists and Agronomists, to get the information on the recent advances on this plant family in regard to physiology and stress tolerance.
