Multi-Scale Integrated Analysis of Agroecosystems by Mario Giampietro Pdf

Ecologists, agronomists, and others who may question the validity of current models for determining sustainable growth of agroecosystems, need a new set of analytical tools that more effectively address the complex nature of related processes. Those who challenge traditional assumptions of optimization and static factors in agricultural modeling demand new methods beyond differential equations and traditional statistical tests. Multi-Scale Integrated Analysis of Agroecosystems explores alternative ways to study agricultural sustainability, presenting new approaches to organizing data and applying complex systems theory to actual cases. This innovative text recognizes the changing dynamics of the multiple processes and cross-relations within an environment, proposing a clearer analysis of agroecosystems than that which can be provided by rigid, reductionist methods. Main concepts, new vocabulary and narratives, and practical examples open the book, followed by technical chapters that provide a more detailed explanation of concepts. The final section of the book presents a tool kit based on these concepts, resulting in strong support of empirical observations that challenge traditional notions regarding the sustainability of farming systems, food systems, and agroecosystems.

Energy and Agriculture by G. Stanhill Pdf

Energy and agriculture are both extremely broad subjects and their interactions - the subject of this book - cover almost the full spectrum of the agricultural sciences. Yet the subject is a relatively new one whose importance first received widespread recognition barely a decade ago, following the dramatic increase in oil prices during 1973. The impact of this increase was such as to promote a world-wide debate on the future direction that agriculture should take. This debate was, and is, of particular concern in countries where agriculture plays a leading role in economic and social development. During the last half century many national agricultural systems have been transformed from almost closed, self-sufficient systems with few locally produced inputs geared to satisfy local requirements, to intensive, open systems, utilizing large quantities of energy-rich inputs such as fossil fuel for manufactured agro-chemicals, water distribution and imported animal feedstuffs to produce a range of sophisticated products, often for export, which in tum require many energy-rich inputs for their marketing. This industrialization of agriculture has proved to be very successful in many respects and indeed was accepted as a general model for agricultural development allowing increased productivity and efficiency per unit land, labor and water, even in areas with limited natural resources.

Energy in Farm Production by R.C. Fluck Pdf

This last volume of the Energy in World Agriculture series is in many ways the series' Alpha and its Omega. It addresses the broad issues related to the use of energy in agricultural production, and also characterizes and quantifies the energy involvements of many agricultural production technologies. It is a compilation of descriptive and analytical information and design principles and data of energy use in this field. A significant aspect is the relationship between energy and agricultural productivity, increased knowledge and resulting improved management of energy-consuming operations on the farm. Information provided here has not been published elsewhere before. Throughout the book are examples of the important role that energy inputs have played in increasing productivity of the world's agricultural systems. Together with a revived interest in energy for agricultural production due to increases in energy costs, this volume meets that interest with valuable information and insights.

Soil Health and Intensification of Agroecosystems by Mahdi M. Al-Kaisi,Birl Lowery Pdf

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

Structure and Function in Agroecosystem Design and Management by Masae Shiyomi,Hiroshi Koizumi Pdf

Structure and Function in Agroecosystem Design and Management presents an advanced discussion of the need to design agricultural systems that 1) increase reliance on biological interactions in agroecosystems as a means of decreasing dependence on the use of large quantities of agrochemicals and the consumption of fossil fuel energy and 2) continue to produce optimal crop yields. Written by international experts, this book discusses biological interactions, matter circulation, and disturbance operating within the agroecosystems in question. The book covers matter cycling and focuses on reducing practices that require the consumption of large quantities of agrochemicals and fossil fuels. The editors then explore the effects of environmental changes and how they will change the management of the next generation of agroecosystems. Is it possible to replace current technologies based on fossil energy with proper interactions operating between crops, livestock, and other organisms to enhance production? If the answer is yes, then modern agriculture can be transformed into an integrated system in which the use of complex biotic interactions is the key technology. Structure and Function in Agroecosystem Design and Management focuses on how can work when designed according to sound ecological practices, and provides the foundation to manage them in an ecologically efficient manner.

Agroecosystem Sustainability by Stephen R. Gliessman Pdf

Agroecologists from around the world share their experiences in the analysis and development of indicators of agricultural sustainability in Agroecosystem Sustainability: Developing Practical Strategies. The authors build on the resource-conserving aspects of traditional, local, and small-scale agriculture while at the same time drawing on modern ecological knowledge and methods. They define the relationship between agroecology and sustainable development. Leading researchers present case studies that attempt to determine 1) if a particular agricultural practice, input, or management decision is sustainable, and 2) what is the ecological basis for the functioning of the chosen management strategy over the long term. They discuss common findings, define the future role of agroecology, and explore strategies for helping farmers make the transition to sustainable farming systems. Preserving the productivity of agricultural land over the long term requires sustainable food production. Agroecosystem Sustainability: Developing Practical Strategies covers topics that range from management practices specific to a particular region to more global efforts to develop sets of indicators of sustainability. It links social and ecological indicators of sustainability. From this foundation we can move towards the social and economic changes that promote sustainability in all sectors of the food system.

From nature-negative to nature-positive production by Ferri, M., Arnés García, M. Pdf

Following the 2021 United Nations Food System Summit call for implementing nature-positive production, this document provides an overview on the conceptual, theoretical and operational aspects of nature-positive production agriculture. The concept of nature-positive production revolves around the possible synergies between ecosystem restoration and food/biomass production and among biodiversity, nature and agriculture. This document tries to answer such questions as “What does nature positive exactly mean?” and “How can agriculture aid in ecosystem restoration?” The thermodynamic perspective is chosen as the privileged viewpoint that allows for a joint analysis from both an ecological and agronomic perspective. This document discusses the inherent functioning of agroecosystems by analysing how ecosystems naturally develop their own sustainability and productivity; it concludes that the most critical systemic features in this regard are complexity, energy storage and energy mobilization capacities. In agroecosystems, these three features are mostly linked with biomass availability, biodiversity, soil health and landscape diversity. The nexus of biodiversity and productivity is therefore uncovered, highlighting the need for a renewed relationship between biodiversity and agriculture. After defining the most relevant theoretical aspects of nature-positive production agriculture, this document provides methodologies for assessing the energy efficiency of an agroecosystem and its agroecological performance. Finally, five priority operational areas are proposed to lead the actual implementation of NPPA: soil and water conservation; soil improvement; evolutionary populations; integrating crops, forestry, livestock and aquaculture; and integrated pest management.
