About the book: Mathematical modeling and computer simulation make it possible to understand and control the dynamic processes taking place in complex systems. Simulation provides insights into the often surprising diversity of possible behaviors, and allows identifying possibilities for intervention and options for alternative development. About one hundred simulation models from all areas of life are fully documented in the three volumes of the 'System Zoo'. They can be quickly implemented and easily operated using freely available system dynamics software. Volume 3 of the System Zoo contains simulation models of economic and social systems and global development, among them: production, stocks and orders, marketing and consumption, competition, life planning, employment, ecotax, escalation, dependence, aggression, population and community development, debt crisis, globalization, the world models of the Club of Rome (by Forrester and the Meadows group) and examples of nonnumerical knowledge processing applied to impact assessment and decision processes. The System Zoo collection of simulation models is particularly well-suited for teaching, training, and research projects at all levels from high school to university, and for individual study. Volume 1 of the System Zoo contains simulation models of elementary systems, and of systems from the fields of physics and engineering. Volume 2 of the System Zoo presents simulation models related to climate, vegetation, ecosystems and resources.

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.

This book makes the case for a systems approach to small-scale community development projects. It specifically looks at the application of one branch of systems science, called system dynamics, to develop conceptual models of small-scale communities and address specific issues they might be facing at different scales. A systems approach recognizes that, by definition, communities are complex adaptive systems consisting of multiple subsystems and parts (e.g., individuals, institutions, and infrastructure) that are interconnected, driven by some purpose, follow certain rules, and interact with each other and with their surrounding environment. In order to address community issues and problems, complexity and uncertainty must be embraced and dealt with. Inside, the author emphasizes and shows how to include a system- and complexity-aware approach in the different phases of small-scale community project management. Adopting this approach comes with unique challenges such as dealing with ill-defined problems, considering uncertainty, recognizing that no unique and best solutions to complex problems exist, and accepting satisficing solutions. The text demonstrates the need for community development practitioners to integrate in all stages of their projects: participation, systems thinking, continuous reflection-in-action, and a combination of critical and creative tools.

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.
