Systems Analysis and Modeling in Food and Agriculture is a component of Encyclopedia of Food and Agricultural Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Systems analysis and modeling is being used increasingly in understanding and solving problems in food and agriculture. The purpose of systems analysis is to support decisions by emphasizing the interactions of processes and components within a system. Frequently investigated systems level questions in agriculture and food are relevant to the 6 E's: Environment, Energy, Ecology, Economics, Education, and Efficiency. The theme on Systems Analysis and Modeling in Food and Agriculture with contributions from distinguished experts in the field provides information on key topics related to food and agricultural system. The coverage include an overview of food system; system level aspects related to energy, environment, and social/policy issues; knowledge bases and decision support; computer models for crops, food processing, water resources, and agricultural meteorology; collection and analysis methods for data from field experiments; use of models and information systems. This volume is aimed at the following a wide spectrum of audiences from the merely curious to those seeking in-depth knowledge: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.

Over the last 11,700 years, during which human civilization developed, the earth has existed within what geologists refer to as the Holocene Epoch. Now science is telling us that the Holocene Epoch in the geological time scale ended, replaced by the onset of a new, more dangerous Anthropocene Epoch, which began around 1950. The Anthropocene Epoch is characterized by an “anthropogenic rift” in the biological cycles of the Earth System, marking a changed reality in which human activities are now the main geological force impacting the earth as a whole, generating at the same time an existential crisis for the world’s population. What caused this massive shift in the history of the earth? In this comprehensive study, John Bellamy Foster tells us that a globalized system of capital accumulation has induced humanity to foul its own nest. The result is a planetary emergency that threatens all present and future generations, throwing into question the continuation of civilization and ultimately the very survival of humanity itself. Only by addressing the social aspects of the current planetary emergency, exploring the theoretical, historical, and practical dimensions of the capitalism’s alteration of the planetary environment, is it possible to develop the ecological and social resources for a new journey of hope.

This book explains why conventional energy analysis and statistics are not useful for generating robust energy scenarios and effective assessments of the quality of alternative energy sources. Then it presents an innovative multi-scale approach, illustrated with empirical results, for effectively dealing with sustainability in face of the coming energy crisis.

The Ecology of Seashores explores the complex shore environment. It covers the ways in which representative species have adapted to life in a constantly changing environment in terms of their interactions, the control of community structure, and how energy and materials are cycled in different ecosystems. Written by an eminent marine biologist,

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.

Power and social inequality shape patterns of land use and resource management. This book explores this relationship from different perspectives, illuminating the complexity of interactions between human societies and nature. Most of the contributors use the perspective of "political ecology" as a point of departure, recognizing that human relations to the environment and human social relations are not separate phenomena but inextricably intertwined. What makes this volume unique is that it sets this approach in a trans-disciplinary, global, and historical framework.
