Book Synopsis Nitrogen in the Environment: Sources, Problems and Management by : R.F. Follett
Download or read book Nitrogen in the Environment: Sources, Problems and Management written by R.F. Follett and published by Gulf Professional Publishing. This book was released on 2001-12-03 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen in the Environment: Sources, Problems, and Management is the first volume to provide a holistic perspective and comprehensive treatment of nitrogen from field, to ecosystem, to treatment of urban and rural drinking water supplies, while also including a historical overview, human health impacts and policy considerations. It provides a worldwide perspective on nitrogen and agriculture. Nitrogen is one of the most critical elements required in agricultural systems for the production of crops for feed, food and fiber. The ever-increasing world population requires increasing use of nitrogen in agriculture to supply human needs for dietary protein. Worldwide demand for nitrogen will increase as a direct response to increasing population. Strategies and perspectives are considered to improve nitrogen-use efficiency. Issues of nitrogen in crop and human nutrition, and transport and transformations along the continuum from farm field to ground water, watersheds, streams, rivers, and coastal marine environments are discussed. Described are aerial transport of nitrogen from livestock and agricultural systems and the potential for deposition and impacts. The current status of nitrogen in the environment in selected terrestrial and coastal environments and crop and forest ecosystems and development of emerging technologies to minimize nitrogen impacts on the environment are addressed. The nitrogen cycle provides a framework for assessing broad scale or even global strategies to improve nitrogen use efficiency. Growing human populations are the driving force that requires increased nitrogen inputs. These increasing inputs into the food-production system directly result in increased livestock and human-excretory nitrogen contribution into the environment. The scope of this book is diverse, covering a range of topics and issues from furthering our understanding of nitrogen in the environment to policy considerations at both farm and national scales.
Book Synopsis Fundamentals of Ecological Modelling by : S.E. Jorgensen
Download or read book Fundamentals of Ecological Modelling written by S.E. Jorgensen and published by Elsevier. This book was released on 2011-01-10 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Ecological Modelling: Applications in Environmental Management and Research, Fourth Edition, provides a comprehensive discussion of the fundamental principles of ecological modeling. The first two editions of this book (published in 1986 and 1994) focused on the roots of the discipline the four main model types that dominated the field 30-40 years ago: (1) dynamic biogeochemical models; (2) population dynamic models; (3) ecotoxicological models; and (4) steady-state biogeochemical and energy models. The third edition focused on the mathematical formulations of ecological processes that are included in ecological models. This fourth edition uses the four model types previously listed as the foundation and expands the latest model developments in spatial models, structural dynamic models, and individual-based models. As these seven types of models are very different and require different considerations in the model development phase, a separate chapter is devoted to the development of each of the model types. Throughout the text, the examples given from the literature emphasize the application of models for environmental management and research. - Presents the most commonly used model types with a step-by-step outline of the modeling procedure used for each - Shows readers through an illustrated example of how to use each model in research and management settings - New edition is revised to include only essential theory with a focus on applications - Includes case studies, illustrations, and exercises (case study of an ecological problem with full illustration on how to solve the problem)

Available in PDF, EPUB and Kindle. Book excerpt: Agroecology is the science of applying ecological concepts and principles to the design, development, and management of sustainable agricultural systems. The Ecology of Agroecosystems highlights a collection of alternative agricultural methodologies and philosophies and provides an interdisciplinary approach that bridges the sociopolitical and historical context of agriculture. It includes the technical issues in a serious and ecological fashion and captures the complex merging of ecology, agriculture, politics and economics in both a historical and contemporary context. Readers will learn not only about the ethical and moral elements related to producing food of questionable quality while possibly impairing the environment, but also about the soil chemistry involved.
Book Synopsis Agricultural Ecology and Environment by : B.R. Stinner
Download or read book Agricultural Ecology and Environment written by B.R. Stinner and published by Elsevier. This book was released on 2012-12-02 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increased use of chemical fertilizers and pesticides in crop production has adversely affected both the environment and the agricultural economy. Not only has it led to environmental pollution, but also the increasing costs of chemical inputs and the low prices received for agricultural products have contributed to economic unprofitability and instability.The International Symposium on Agricultural Ecology and Environment was organised in order to discuss ways of achieving the goals of economically and environmentally sustainable agriculture. It is apparent that a truly multidisciplinary effort is required and for this reason the meeting was attended by authors from many different disciplines and geographical locations. Although their papers reflect a wide diversity of agroecosystem types and examples, several common themes emerge: the increased importance of biotic control of ecosystem processes in lower input systems; the key role of soil organic matter in stabilizing nutrient cycling; the importance of agricultural landscape diversity and complexity; the importance of studying ecological processes in natural and agricultural ecosystems; the critical need to integrate socio-economic and ecological approaches.
Book Synopsis Thermodynamics and Ecological Modelling by : Sven E. Jorgensen
Download or read book Thermodynamics and Ecological Modelling written by Sven E. Jorgensen and published by CRC Press. This book was released on 2018-10-03 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermodynamics is used increasingly in ecology to understand the system properties of ecosystems because it is a basic science that describes energy transformation from a holistic view. In the last decade, many contributions to ecosystem theory based on thermodynamics have been published, therefore an important step toward integrating these theories and encouraging a more wide spread use of them is to present them in one volume. An ecosystem consists of interdependent living organisms that are also interdependent with their environment, all of which are involved in a constant transfer of energy and mass within a general state of equilibrium or dis-equilibrium. Thermodynamics can quantify exactly how "organized" or "disorganized" a system is - an extremely useful to know when trying to understand how a dynamic ecosystem is behaving. A part of the Environmental and Ecological (Math) Modeling series, Thermodynamics and Ecology is a book-length study - the first of its kind - of the current thinking on how an ecosystem can be explained and predicted in terms of its thermodynamical behavior. After the introductory chapters on the fundamentals of thermodynamics, the book explains how thermodynamic theory can be specifically applied to the "measurement" of an ecosystem, including the assessment of its state of entropy and enthalpy. Additionally, it will show economists how to put these theories to use when trying to quantify the movement of goods and services through another type of complex living system - a human society.
Book Synopsis A Systems Approach to Agroecology by : Pablo Tittonell
Download or read book A Systems Approach to Agroecology written by Pablo Tittonell and published by Springer Nature. This book was released on 2023-10-14 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: As agroecology gains momentum in the international research-for-development arena, there is an urgent need for methods and tools to support the codesign and evaluation of agroecological systems and their transitions. The social and ecological complexity of agroecosystems, their dynamics, uncertainties and sustainability, calls for a holistic, systemic approach to agroecology. As such, several questions arise for example: how do we deal with heterogeneity, landscapes, biodiversity or learning processes in agroecosystems analysis? How do we categorise diversity or analyse trade-offs in social-ecological interactions? How do we conceptualise, codesign and monitor agroecological transitions? This book sets out to answer these questions by building on the valuable ‘classics’ in agroecology. The book presents a systems perspective that underpins a combination of methodologies, ranging from participatory tools and field observations to mathematical simulation modelling. Researchers, advanced students and transdisciplinary practitioners will find in this book insights and methods to design research and (co-) innovation processes to foster agroecological transitions.

Book Synopsis Power, Production and Social Reproduction by : S. Gill
Download or read book Power, Production and Social Reproduction written by S. Gill and published by Springer. This book was released on 2003-09-30 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by leading authorities from Europe, the Americas and Asia, this path-breaking work develops an innovative and original theorization of global political economy. Whilst most approaches theorize global political economy from the perspectives of power and production or states and markets, this work argues that what feminists call social reproduction is a more basic framework, upon which most forms of power and production, and states and markets, must necessarily rest. By combining Feminist and Radical Political Economy with Critical International Studies, the volume explores how global transformations of states, growth in the power of capital, and extension of market values and market forces in everyday life, all affect the security of the majority of the population, and the reproduction of communities and societies. The book shows how public and private forms of power regulate three main aspects of social reproduction: biological reproduction; reproduction of labour power; and social practices connected to caring and provisioning of human needs.
Book Synopsis Ecological Intensification of Natural Resources for Sustainable Agriculture by : Manoj Kumar Jhariya
Download or read book Ecological Intensification of Natural Resources for Sustainable Agriculture written by Manoj Kumar Jhariya and published by Springer Nature. This book was released on 2021-03-07 with total page 655 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological intensification involves using natural resources such as land, water, soil nutrients, and other biotic and abiotic variables in a sustainable way to achieve high performance and efficiency in agricultural yield with minimal damage to the agroecosystems. With increasing food demand there is high pressure on agricultural systems. The concept of ecological intensification presents the mechanisms of ensuring high agricultural productivity by restoration the soil health and landscape ecosystem services. The approach involves the replacement of anthropogenic inputs with eco-friendly and sustainable alternates. Effective ecological intensification requires an understanding of ecosystems services, ecosystem's components, and flow of resources in the agroecosystems. Also, awareness of land use patterns, socio-economic factors, and needs of the farmer community plays a crucial role. It is therefore essential to understand the interaction of ecosystem constituents within the extensive agricultural landscape. The editors critically examined the status of ecological stress in agroecosystems and address the issue of ecological intensification for natural resources management. Drawing upon research and examples from around the world, the book is offering an up-to-date account, and insight into the approaches that can be put in practice for poly-cropping systems and landscape-scale management to increase the stability of agricultural production systems to achieve ‘Ecological resilience’. It further discusses the role of farmer communities and the importance of their awareness about the issues. This book will be of interest to teachers, researchers, climate change scientists, capacity builders, and policymakers. Also, the book serves as additional reading material for undergraduate and graduate students of agriculture, forestry, ecology, agronomy, soil science, and environmental sciences. National and international agricultural scientists, policymakers will also find this to be a useful read for green future.
Book Synopsis Below-ground Interactions in Tropical Agroecosystems by : Meine van Noordwijk

Available in PDF, EPUB and Kindle. Book excerpt: Below-grownd interactions are often seen as the 'dark side' of agroecosystems, especially when more than one crop is grown on the same piece of land at he same time. this book aims to review the amount of light he past decade of research has shed on this topic. It also aims to review ohw far we have come in unravelling the positive and negative aspects of these interactions and how, in dialogue with farmers, we can use the generic principles that are now emerging to look for sita-specifics solutions.
Book Synopsis Agro-Ecological Intensification of Agricultural Systems in the African Highlands by : Bernard Vanlauwe
Download or read book Agro-Ecological Intensification of Agricultural Systems in the African Highlands written by Bernard Vanlauwe and published by Routledge. This book was released on 2013-12-17 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is an urgent need to increase agricultural productivity in sub-Saharan Africa in a sustainable and economically-viable manner. Transforming risk-averse smallholders into business-oriented producers that invest in producing surplus food for sale provides a formidable challenge, both from a technological and socio-political perspective. This book addresses the issue of agricultural intensification in the humid highland areas of Africa – regions with relatively good agricultural potential, but where the scarce land resources are increasingly under pressure from the growing population and from climate change. In addition to introductory and synthesis chapters, the book focuses on four themes: system components required for agricultural intensification; the integration of components at the system level; drivers for adoption of technologies towards intensification; and the dissemination of complex knowledge. It provides case studies of improved crop and soil management for staple crops such as cassava and bananas, as well as examples of how the livelihoods of rural people can be improved. The book provides a valuable resource for researchers, development actors, students and policy makers in agricultural systems and economics and in international development. It highlights and addresses key challenges and opportunities that exist for sustainable agricultural intensification in the humid highlands of sub-Saharan Africa.
