Abstract

Die zur techno-ökonomische Analyse von Luftreinhaltestrategien verwendeten Optimiermodelle vernachlässigen in ihrer Zielfunktion die einzelbetriebliche Investitionsentscheidung. Diese stellt jedoch die Grundlage für den Einsatz von Emissionsminderungsmaßnahmen auf Anlagenebene dar. Das beschriebene systemdynamische Modell erlaubt die Analyse der Auswirkungen umweltpolitischer Instrumente auf die betrieblichen Rahmenbedingungen und Kosten und somit auf die erreichbare Emissionsminderung.

Abstract

The issues facing humanity have become increasingly complex due to the fact they are embedded in a global web of ecological, economic, social, cultural and political processes that are dynamically interlinked. The capacity to conceptualise and redesign solutions, in systems and sustainability terms, will increasingly be what society and employers expect. This “expectation” is globally one of the biggest challenges for education. This Special Issue highlights key developments in the area of systems education and how some of the many challenges are currently being addressed. The 15 articles published fall into five groups: how to design learning systems for systems thinking and sustainability education; insights from the various systems education programs available internationally; different approaches to teaching systems thinking and sustainability; how systems education can be tailored to broaden systems education beyond universities; and possible future pathways for systems education for a sustainable planet. The range and magnitude of the contributions to this book illustrate the diversity of systems education practices and programs (learning systems) in the global systems community, and the relevance of systems thinking and practice to examining issues crucial to the long-term sustainability of the planet.

Abstract

Systems studied in environmental science, due to their structure and the heterogeneity of the entities composing them, often exhibit complex dynamics that can only be captured by hybrid modeling approaches. While several concurrent definitions of “hybrid modeling” can be found in the literature, it is defined here broadly as the approach consisting in coupling existing modelling paradigms to achieve a more accurate or efficient representation of systems. The need for hybrid models generally arises from the necessity to overcome the limitation of a single modeling technique in terms of structural flexibility, capabilities, or computational efficiency. This book brings together experts in the field of hybrid modelling to demonstrate how this approach can address the challenge of representing the complexity of natural systems. Chapters cover applied examples as well as modeling methodology.Systems studied in environmental science, due to their structure and the heterogeneity of the entities composing them, often exhibit complex dynamics that can only be captured by hybrid modeling approaches.

Abstract

River catchments and reservoirs play a central role in water security, food supply, flood risk management, hydropower generation, and ecosystem services; however, they are now under increasing pressure from population growth, economic activities, and changing climate means and extremes in many parts of the world. Adaptive management of river catchments and reservoirs requires an in-depth understanding of the impacts of future uncertainties and thus the development of robust, sustainable solutions to meet the needs of various stakeholders and the environment. To tackle the huge challenges in moving towards adaptive catchment management, this book presents the latest developments in cutting-edge knowledge, novel methodologies, innovative management strategies, and case studies, focusing on the following themes: reservoir dynamics and impact analysis of dam construction, optimal reservoir operation, climate change impacts on hydrological processes and water management, and integrated catchment management.
