Available in PDF, EPUB and Kindle. Book excerpt: While modern science has always recognized the central role that biodiversity plays in the ecological processes that maintain the Earth's equilibrium, our increasing knowledge of nature has deepened our appreciation of this principle. Consequently, those involved with implementing and maintaining sustainable agriculture systems have begun to take a far more sophisticated approach to understanding and making use of the components and mechanics of biodiversity. Providing a comprehensive and highly practical exploration of the subject, Biodiversity in Agricultural Production Systems examines abiotic ecosystem diversity and biological complexity at every relevant level. Leading researchers detail subspecies diversity, covering ecotypes, lifecycles, genes, physiology, and behavior. They also discuss species richness and supraspecies diversity, which includes foodweb interactions and non-trophic relationships, as well as above- and belowground relationships. Exploring various facets of agricultural crops and cultivation practices, this inter-disciplinary volume- Gives an overview of the pore space dynamic in agroecosystems where most soil microorganisms reside, including bacteria, fungi, protozoa, nematodes, and Tardigrada Examines the highly diverse and prominent role played by earthworms Looks at the metabolic processes occurring in soils that result in the release of greenhouse gases Outlines principles and strategies of order between interacting molecules, cells, species and communities Looks at mechanisms of competition, exploring growth regulation, transformation, and feeding strategies, as well as toxin production, mutation, and biofilm formation Discusses matter recycling and the diversity of microbial metabolism in soils Shows how long-term observation plots are used to assess soil quality Biodiversity in Agricultural Production Systems provides important information for those involved with researching and implementing sustainable agricultural systems, as well as those addressing specific challenges related to soil degradation, water management, and climatic impacts. It also provides recent research and fresh perspectives to enhance the approaches of those working in horticulture, biology, and the environmental sciences.

Download or read book Soil Organic Matter and Feeding the Future written by Rattan Lal and published by CRC Press. This book was released on 2021-12-09 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil organic matter (SOM) is the primary determinant of soil functionality. Soil organic carbon (SOC) accounts for 50% of the SOM content, accompanied by nitrogen, phosphorus, and a range of macro and micro elements. As a dynamic component, SOM is a source of numerous ecosystem services critical to human well-being and nature conservancy. Important among these goods and services generated by SOM include moderation of climate as a source or sink of atmospheric CO2 and other greenhouse gases, storage and purification of water, a source of energy and habitat for biota (macro, meso, and micro-organisms), a medium for plant growth, cycling of elements (N, P, S, etc.), and generation of net primary productivity (NPP). The quality and quantity of NPP has direct impacts on the food and nutritional security of the growing and increasingly affluent human population. Soils of agroecosystems are depleted of their SOC reserves in comparison with those of natural ecosystems. The magnitude of depletion depends on land use and the type and severity of degradation. Soils prone to accelerated erosion can be strongly depleted of their SOC reserves, especially those in the surface layer. Therefore, conservation through restorative land use and adoption of recommended management practices to create a positive soil-ecosystem carbon budget can increase carbon stock and soil health. This volume of Advances in Soil Sciences aims to accomplish the following: Present impacts of land use and soil management on SOC dynamics Discuss effects of SOC levels on agronomic productivity and use efficiency of inputs Detail potential of soil management on the rate and cumulative amount of carbon sequestration in relation to land use and soil/crop management Deliberate the cause-effect relationship between SOC content and provisioning of some ecosystem services Relate soil organic carbon stock to soil properties and processes Establish the relationship between soil organic carbon stock with land and climate Identify controls of making soil organic carbon stock as a source or sink of CO2 Connect soil organic carbon and carbon sequestration for climate mitigation and adaptation

Available in PDF, EPUB and Kindle. Book excerpt: Soil Health and Intensification of Agroecosystems examines the climate, environmental, and human effects on agroecosystems and how the existing paradigms must be revised in order to establish sustainable production. The increased demand for food and fuel exerts tremendous stress on all aspects of natural resources and the environment to satisfy an ever increasing world population, which includes the use of agriculture products for energy and other uses in addition to human and animal food. The book presents options for ecological systems that mimic the natural diversity of the ecosystem and can have significant effect as the world faces a rapidly changing and volatile climate. The book explores the introduction of sustainable agroecosystems that promote biodiversity, sustain soil health, and enhance food production as ways to help mitigate some of these adverse effects. New agroecosystems will help define a resilient system that can potentially absorb some of the extreme shifts in climate. Changing the existing cropping system paradigm to utilize natural system attributes by promoting biodiversity within production agricultural systems, such as the integration of polycultures, will also enhance ecological resiliency and will likely increase carbon sequestration. - Focuses on the intensification and integration of agroecosystem and soil resiliency by presenting suggested modifications of the current cropping system paradigm - Examines climate, environment, and human effects on agroecosystems - Explores in depth the wide range of intercalated soil and plant interactions as they influence soil sustainability and, in particular, soil quality - Presents options for ecological systems that mimic the natural diversity of the ecosystem and can have significant effect as the world faces a rapidly changing and volatile climate

Book excerpt: Soil and Fertilizers: Managing the Environmental Footprint presents strategies to improve soil health by reducing the rate of fertilizer input while maintaining high agronomic yields. It is estimated that fertilizer use supported nearly half of global births in 2008. In a context of potential food insecurity exacerbated by population growth and climate change, the importance of fertilizers in sustaining the agronomic production is clear. However, excessive use of chemical fertilizers poses serious risks both to the environment and to human health. Highlighting a tenfold increase in global fertilizer consumption between 2002 and 2016, the book explains the effects on the quality of soil, water, air and biota from overuse of chemical fertilizers. Written by an interdisciplinary author team, this book presents methods for enhancing the efficiency of fertilizer use and outlines agricultural practices that can reduce the environmental footprint. Features: Includes a thorough literature review on the agronomic and environmental impact of fertilizer, from degradation of ecosystems to the eutrophication of drinking water Devotes specific chapters to enhancing the use efficiency and effectiveness of the fertilizers through improved formulations, time and mode of application, and the use of precision farming technology Reveals geographic variation in fertilizer consumption volume by presenting case studies for specific countries and regions, including India and Africa Discusses the pros and cons of organic vs. chemical fertilizers, innovative technologies including nuclear energy, and the U.N.’s Sustainable Development Goals Part of the Advances in Soil Sciences series, this solutions-focused volume will appeal to soil scientists, environmental scientists and agricultural engineers.

Available in PDF, EPUB and Kindle. Book excerpt: Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.

Available in PDF, EPUB and Kindle. Book excerpt: Take a balanced look at ways to ensure food security and to work to erase hunger around the world Agriculture is the most aggressively managed ecosystem. Agricultural Sustainability: Principles, Processes, and Prospects provides a comprehensive examination of all facets of agricultural sustainability, beginning with the history of the evolution of the concept to the present. Challenges to sustainability are clearly presented along with practical strategies to counter prospective problems. This vital resource considers options for the future, as well as reviewing past approaches for their value in today’s world. When one considers that the alternative to agricultural sustainability is the collapse of the world’s food systems, it is understood that compromise is impossible. Agricultural Sustainability takes a holistic approach to the issues that are involved in making agriculture ecologically sound, economically viable, and socially responsible around the world. The book is divided into three parts. Part One clarifies the concept of agricultural sustainability, bringing a rational and balanced view of the core elements. Part Two discusses ways to promote sustainability in the world, including practical scientific and technological processes for improving yields while ensuring food security for future generations. Part Three peers into future decades, reviewing the vision documents of international agencies, their perceptions and expectations for the years ahead, and present dysfunctional aspects in the current food system. The book is extensively referenced and includes figures and charts to clearly explain data. The book examines: the historic evolution of the concept of agricultural sustainability the combined effects of a multiplicity of agricultural systems concepts for validating the sustainability of a production system the role of natural capital in production the role of science and technology in sustainable use managing land, water, biodiversity, and energy quantitative approaches to measuring agricultural sustainability the current status of agricultureand predictions for its growth in the coming decades case studies of agricultural growth from India and China problemsand possibilitiesof creating a hunger-free world by the end of this century Agricultural Sustainability is crucial, enlightening reading for field workers in NGOs and agricultural extensions; personnel in local, national, and international developmental organizations; and educators and students of sustainable agricultural production, food security, rural development, environmental science, and the conservation of natural resources.
