A Systems Approach to Modeling the Water-Energy-Land-Food Nexus, Volume II by Bernard Amadei Pdf

This two-volume book describes a flexible and adaptive system-based methodology and associated guidelines for the management and allocation of community-based WELF resources. Over the next 50 years, rapid population, urbanization, and economic growth worldwide will create unprecedented demands for water, energy, land, and food (WELF) resources. The discussion on how to meet human needs for WELF resources and how to guarantee their respective securities has changed over time from looking at all four sectors in isolation to understanding their interdependency through the so-called WELF nexus. The approach presented in this book responds to the overall agreement in the WELF nexus literature that the management and allocation of WELF resources at the community level need to be examined in a more systemic, multidisciplinary, participatory, and practical manner while seeking to increase synergies and reduce trade-offs. This book was written to explore the value proposition of that approach. This two-volume book describes a flexible and adaptive system-based methodology and associated guidelines for the management and allocation of community-based WELF resources. Volume 1 focuses on defining the landscape in which the nexus operates and outlines the proposed methodology. Volume 2 explores the quantitative and qualitative modeling of the nexus and landscape using system modeling tools including system dynamics. It presents a road map for the formulation, simulation, selection, and ranking of possible intervention plans. The proposed methodology is designed to serve as a guide for different groups involved in the science and policy decision aspects of the WELF nexus within the context of community development. The methodology focuses mostly on WELF-related issues in small-scale and low-income communities where securing resources is critical to their short- and long-term livelihood and development.

Navigating the Complexity Across the Peace–Sustainability–Climate Security Nexus by Bernard Amadei Pdf

Promoting peace and sustainability in human development while accounting for the risks associated with the impact of climate change on society has become more imperative than ever when addressing humanity's challenges of the twenty-first century. There is enough evidence that peace, sustainability, and climate security are entangled with multiple complex interactions and cannot be dealt with in isolation and independently from the environment and the numerous systems with which they interact. Yet, the intersection of peace, sustainability, and climate security or their opposites (i.e., conflict, unsustainability, and climate vulnerability) is rarely articulated with a systemic mindset. A multi-solving nexus approach is more appropriate to capture the complexity and uncertainty of how the three sectors of peace, sustainability, and climate security play a role in community development, the nature of their causal chains, and the feedback on how community development affects the three sectors. Navigating the Complexity Across the Peace–Sustainability–Climate Security Nexus explores the value proposition of using a systems approach, methodology, and tools to comprehend and model that dynamic. Features of the book: Explores the interaction between the different components of peace and the relationship between peace, sustainability, and climate security using semi-qualitative and quantitative tools; Explains how climate adaptation and mitigation are related to peace or conflict; Presents generic system dynamics modeling that can be used in different contexts.

Patient safety in health systems has become more and more important as a theme in health research, and so it is not surprising to see a growing interest in applying systems thinking to healthcare. However there is a difficulty – health systems are very complex and constantly adapting to respond to core drivers and fit needs. How do you apply systems thinking in this situation, and what methods are available? National health authorities, international donors and research practitioners need to know the “how-to” of conducting health systems research from a systems thinking perspective. This book will fill this gap and provide a range of tools that give clear guidance of ways to carry out systems thinking in health. These methodologies include: System dynamics and causal loops Network analysis Outcome mapping Soft systems methodology Written by an international team of experts in health research, this handbook will be essential reading for those working in or researching public health, health policy, health systems, global health, service improvement and innovation in practice.

Systems and Models by Hartmut Bossel Pdf

A multitude of complex systems and actors pursuing their own agenda shape the dynamics of our world. Better understanding of their actions and interactions is crucial, and can be achieved by a profound knowledge of systems and their properties, and their representation in models allowing simulation of probable behavior. Drawing on his extensive research and teaching experience in modeling and simulation of a wide range of systems - from engineering to social systems and ecosystems - the author presents the fundamental concepts and approaches for understanding and modeling the complex systems shaping the dynamics of our world. The book applies state space analysis and system dynamics to deal with the dynamic processes of "causal systems," discusses information processing approaches for modeling decision processes of "actors" and "agents," and uses aspects of the coevolutionary development of systems in their environment to deal with normative orientation, ethics, and evaluation of policies and long-term development. The concepts are applied in particular to the issue of sustainable development of human society in an evolving world. The book is complemented by a survey of system topics and of models from many fields, and by an extensive bibliography on the many systems-related subjects covered. Hartmut Bossel is Professor Emeritus of environmental systems analysis. He taught for many years at the University of California in Santa Barbara and the University of Kassel, Germany, where he was director of the Center for Environmental Systems Research until his retirement. He holds an engineering degree from the Technical University of Darmstadt, and a Ph.D. degree from the University of California at Berkeley. With a background in engineering, systems science, and mathematical modeling, he has led many research projects and future studies in different countries, developing computer simulation models and decision support systems in the areas of energy supply policy, global dynamics, orientation of behavior, agricultural policy, and forest dynamics and management. He has written numerous books on modeling and simulation of dynamic systems, social change and future paths, and has published widely in the scientific literature in several fields. Bossel is author of a System Zoo containing over one hundred simulation models of diverse systems.

Modeling and Simulation by Hartmut Bossel Pdf

Models and simulations of all kinds are tools for dealing with reality. Humans have always used mental models to better understand the world around them: to make plans, to consider different possibilities, to share ideas with others, to test changes, and to determine whether or not the development of an idea is feasible. The book Modeling and Simulation uses exactly the same approach except that the traditional mental model is translated into a computer model, and the simulations of alternative outcomes under varying conditions are programmed on the computer. The advantage of this method is that the computer can track the multitude of implications and consequences in complex relationships much more quickly and reliably than the human mind. This unique interdisciplinary text not only provides a self contained and complete guide to the methods and mathematical background of modeling and simulation software (SIMPAS) and a collection of 50 systems models on an accompanying diskette. Students from fields as diverse as ecology and economics will find this clear interactive package an instructive and engaging guide.

Thinking in Systems by Donella Meadows Pdf

The classic book on systems thinking—with more than half a million copies sold worldwide! "This is a fabulous book... This book opened my mind and reshaped the way I think about investing."—Forbes "Thinking in Systems is required reading for anyone hoping to run a successful company, community, or country. Learning how to think in systems is now part of change-agent literacy. And this is the best book of its kind."—Hunter Lovins In the years following her role as the lead author of the international bestseller, Limits to Growth—the first book to show the consequences of unchecked growth on a finite planet—Donella Meadows remained a pioneer of environmental and social analysis until her untimely death in 2001. Thinking in Systems is a concise and crucial book offering insight for problem solving on scales ranging from the personal to the global. Edited by the Sustainability Institute’s Diana Wright, this essential primer brings systems thinking out of the realm of computers and equations and into the tangible world, showing readers how to develop the systems-thinking skills that thought leaders across the globe consider critical for 21st-century life. Some of the biggest problems facing the world—war, hunger, poverty, and environmental degradation—are essentially system failures. They cannot be solved by fixing one piece in isolation from the others, because even seemingly minor details have enormous power to undermine the best efforts of too-narrow thinking. While readers will learn the conceptual tools and methods of systems thinking, the heart of the book is grander than methodology. Donella Meadows was known as much for nurturing positive outcomes as she was for delving into the science behind global dilemmas. She reminds readers to pay attention to what is important, not just what is quantifiable, to stay humble, and to stay a learner. In a world growing ever more complicated, crowded, and interdependent, Thinking in Systems helps readers avoid confusion and helplessness, the first step toward finding proactive and effective solutions.

Connecting People to Their Oceans: Issues and Options for Effective Ocean Literacy by Angel Borja,Francesca Santoro,Gail Scowcroft,Stephen Fletcher,Pierre Strosser Pdf

While there is growing evidence of the importance of marine ecosystems for our societies, evidence shows also that pressures from human activities on these ecosystems are increasing, putting the health of marine ecosystems at stake worldwide. Hence, Blue Economy is becoming an important component of future socio-economic development strategies (e.g. this is called Blue Growth in Europe), that eventually can result in increasing pressures at sea, and despite the current regulatory framework (in particular with the Oceans Act, in USA or Canada, and the Marine Strategy Framework Directive, in Europe), it is likely that this situation will continue in the future. Ensuring all those connected to the sea, directly or indirectly, gain a better understanding of the importance of the seas, the human-sea interactions and opportunities to act better and reduce impacts from human pressures, is central to Ocean Literacy (OL). Receiving increasing attention in Europe and USA, OL is a challenge for all parts of society: educators & trainers, children and professionals, civil society and scientists, consumers and policy/decision makers. It is seen as part of the package of solutions that will lead to a change in behavior and practice, thus reducing impacts and resulting in healthier marine ecosystems, whilst allowing development opportunities offered by seas are seized in a sustainable manner. This Research Topic focuses on the issues and options for effective OL worldwide. It discusses: (1) existing experiences in OL (formal and informal education for children, training for professionals, tools for raising awareness of consumers - and of investors in the marine sectors...) and their effectiveness (from understanding better to acting differently); (2) the role OL could play (in interaction with innovation, regulation, economic incentive, social norms...) to support human capital development as key component of sustainable growth; and (3) pre-conditions for effective OL for different sectors and target groups. Questions relevant to OL include: Which knowledge - produced by whom - to share and how? Who to target - and how to effectively reach those targeted? How to design OL initiatives - including by mobilizing those targeted (via living lab approaches e.g.) - to ensure effective OL and pave the way for behavior change? What are the knowledge gaps that limit our capacity to design effective OL? As scientists, it is likely you have many more questions to offer and discuss.

Common mistakes in System Dynamics by Juan Martin Garcia Pdf

Creating a simulation model with System Dynamics is not easy, there is the risk of making serious mistakes that force the model to remain unfinished after having dedicated days of work. There are books and courses which show the steps to be taken in the process of creating a simulation model, but it is observed that some errors are repeated frequently. This book offers a different approach, instead of explaining how to create a simulation model, it shows the mistakes that are usually made. The book is designed for students who are looking for a quick manual to identify the most common mistakes made when creating simulation models by applying System Dynamics, to correct them before presenting their research or work. The experts will find in this book a list of points to check before making a presentation to their clients. The content of the book allows the reader to identify the errors described and take them into account before submitting or publishing a work. AN ESSENTIAL BOOK Content Causal Loop Diagram CLD 7 1.

Mathematical Modeling and Simulation by Kai Velten Pdf

This concise and clear introduction to the topic requires only basic knowledge of calculus and linear algebra - all other concepts and ideas are developed in the course of the book. Lucidly written so as to appeal to undergraduates and practitioners alike, it enables readers to set up simple mathematical models on their own and to interpret their results and those of others critically. To achieve this, many examples have been chosen from various fields, such as biology, ecology, economics, medicine, agricultural, chemical, electrical, mechanical and process engineering, which are subsequently discussed in detail. Based on the author`s modeling and simulation experience in science and engineering and as a consultant, the book answers such basic questions as: What is a mathematical model? What types of models do exist? Which model is appropriate for a particular problem? What are simulation, parameter estimation, and validation? The book relies exclusively upon open-source software which is available to everybody free of charge. The entire book software - including 3D CFD and structural mechanics simulation software - can be used based on a free CAELinux-Live-DVD that is available in the Internet (works on most machines and operating systems).
