Book Description
In the last 20 years, there has been a remarkable emergence of innovations and technological advances that are generating promising changes and opportunities for sustainable agriculture, yet at the same time the agricultural sector worldwide faces numerous daunting challenges. Not only is the agricultural sector expected to produce adequate food, fiber, and feed, and contribute to biofuels to meet the needs of a rising global population, it is expected to do so under increasingly scarce natural resources and climate change. Growing awareness of the unintended impacts associated with some agricultural production practices has led to heightened societal expectations for improved environmental, community, labor, and animal welfare standards in agriculture. Toward Sustainable Agricultural Systems in the 21st Century assesses the scientific evidence for the strengths and weaknesses of different production, marketing, and policy approaches for improving and reducing the costs and unintended consequences of agricultural production. It discusses the principles underlying farming systems and practices that could improve the sustainability. It also explores how those lessons learned could be applied to agriculture in different regional and international settings, with an emphasis on sub-Saharan Africa. By focusing on a systems approach to improving the sustainability of U.S. agriculture, this book can have a profound impact on the development and implementation of sustainable farming systems. Toward Sustainable Agricultural Systems in the 21st Century serves as a valuable resource for policy makers, farmers, experts in food production and agribusiness, and federal regulatory agencies.

Book Description
This book . . . is an invitation to all Christians to begin constructing a food ethics; to the academic Christian ethicist, it presents an opportunity to join a discussion on a topic relevant in so many ways to the life of every American; to the Christian for whom the spark of the divine is detectable in the everyday life, it is a chance to begin making ethical sense out of something done every day for the entirety of one's natural life-participating in agriculture. -from the Introduction In Sustainable Agriculture, Mark Graham joins the vibrant, substantive discussion about the moral issues in American agriculture by revealing what is going on in current agricultural practices and analyzing them in light of morality and sustainability. Graham's constructive proposal for change is based on a moral vision that identifies a group of core values around which our agricultural system should be developed, including: a) a consistent, safe food supply; b) vital, sustainable communities; and c) personal and environmental health.

Book Description
Recognition of the importance of soil organic matter (SOM) in soil health and quality is a major part of fostering a holistic, preventive approach to agricultural management. Students in agronomy, horticulture, and soil science need a textbook that emphasizes strategies for using SOM management in the prevention of chemical, biological, and physical problems. Soil Organic Matter in Sustainable Agriculture gathers key scientific reviews concerning issues that are critical for successful SOM management. This textbook contains evaluations of the types of organic soil constituents—organisms, fresh residues, and well-decomposed substances. It explores the beneficial effects of organic matter on soil and the various practices that enhance SOM. Chapters include an examination of the results of crop management practices on soil organisms, organic matter gains and losses, the significance of various SOM fractions, and the contributions of fungi and earthworms to soil quality and crop growth. Emphasizing the prevention of imbalances that lead to soil and crop problems, the text also explores the development of soils suppressive to plant diseases and pests, and relates SOM management to the supply of nutrients to crops. This book provides the essential scientific background and poses the challenging questions that students need to better understand SOM and develop improved soil and crop management systems.

Book Description
This book presents advanced knowledge and techniques to improve food quality, such as organic farming, fertilization using waste, reducing arsenic in food, soil restoration, forage production in arid regions and weed control. Agriculture is actually facing two major challenges, feeding an ever-growing population and providing safe food in the context of pollution, climate change and the future circular economy.

Book Description
Almost a billion people all over the earth suffer from hunger and malnutrition. Many of them are starving while the world's population continues to grow dramatically. The population in the industrialized nations, whose hunger is still abundantly satisfied, must struggle with the costs of heavily subsidized overproduction of food. Still, the worldwide lack of food will also pose a threatening problem to them.

Book Description
This book reviews recent research and applications of chitin and chitosan, as natural alternatives of fossil fuel products, in medicine and pharmacy, agriculture, food science and water treatment. Chitin and chitosan products are polysaccharides derived from food waste of crustaceans and fungi, and thus are cheap, abundant, sustainable, non-toxic, recyclable and biocompatible. Remarkable applications include food additives and preservation, packaging materials, biopesticides and fertilisers, drug delivery, tissue engineering, bioflocculation and dye removal.

Book Description
Sustainable agriculture is a rapidly growing field aiming at producing food and energy in a sustainable way for humans and their children. Sustainable agriculture is a discipline that addresses current issues such as climate change, increasing food and fuel prices, poor-nation starvation, rich-nation obesity, water pollution, soil erosion, fertility loss, pest control, and biodiversity depletion. Novel, environmentally-friendly solutions are proposed based on integrated knowledge from sciences as diverse as agronomy, soil science, molecular biology, chemistry, toxicology, ecology, economy, and social sciences. Indeed, sustainable agriculture decipher mechanisms of processes that occur from the molecular level to the farming system to the global level at time scales ranging from seconds to centuries. For that, scientists use the system approach that involves studying components and interactions of a whole system to address scientific, economic and social issues. In that respect, sustainable agriculture is not a classical, narrow science. Instead of solving problems using the classical painkiller approach that treats only negative impacts, sustainable agriculture treats problem sources. Because most actual society issues are now intertwined, global, and fast-developing, sustainable agriculture will bring solutions to build a safer world.

Book Description
In response to the challenges of a growing population and food security, there is an urgent need to construct a new agri-food sustainability paradigm. This book brings together an integrated range of key social science insights exploring the contributions and interventions necessary to build this framework. Building on over ten years of ESRC funded theoretical and empirical research centered at BRASS, it focuses upon the key social, economic and political drivers for creating a more sustainable food system. Themes include: regulation and governance sustainable supply chains public procurement sustainable spatial strategies associated with rural restructuring and re-calibrated urbanised food systems minimising bio-security risk and animal welfare burdens. The book critically explores the linkages between social science research and the evolving food security problems facing the world at a critical juncture in the debates associated with not only food quality, but also its provenance, vulnerability and the inherent unsustainability of current systems of production and consumption. Each chapter examines how the links between research, practice and policy can begin to contribute to more sustainable, resilient and justly distributive food systems which would be better equipped to ‘feed the world’ by 2050.

Book Description
This book presents recently-developed crop, soil, and management practices that can be used to improve phosphorous use efficiency in agriculture. Food security highly depends on the availability of plant nutrients such as phosphorus, yet rock phosphate reserves are expected to be exhausted in the next 50–100 years. Moreover, about 80% of the phosphorous fertilizers applied to soils become unavailable to plants due to phosphorous fixation in iron and aluminum oxides in acidic soils and with carbonates in alkaline soils. As a consequence, only 10-15% of applied phosphorous is up taken by crops. Therefore, there is a need for advanced practices for improving phosphorus use efficiency.
