A Systems Approach To Ecological Economic Models Developed Progressively In Three Interwoven Articles, Takuro Uehara
A Systems Approach To Ecological Economic Models Developed Progressively In Three Interwoven Articles, Takuro Uehara
Dissertations and Theses
My dissertation develops and analyzes ecological economic models to study the complex dynamics of an ecological economic system (EES) and investigate various conditions and measures which can sustain a developing economy over the long term in view of resilience and sustainability. Because of the intrinsic complexity of the system, I take a systems approach, using economics as the foundation for the basic structure of an ecological economic model, and system dynamics as the method to build and analyze such a complex ecological economic model. Throughout my dissertation, the model developed by Brander and Taylor (1998) is adopted as a baseline …

Understanding the way regional landscapes operate, evolve, and change is a key area of research for ecosystem science. It is also essential to support the "placebased" management approach being advocated by the U.S. Environmental Protection Agency and other management agencies. We developed a spatially explicit, process-based model of the 2352 km2 Patuxent River watershed in Maryland to integrate data and knowledge over several spatial, temporal, and complexity scales, and to serve as an aid to regional management. In particular, the model addresses the effects of both the magnitude and spatial patterns of human settlements and agricultural practices on hydrology, plant …
Visions, Values, Valuation And The Need For An Ecological Economics, Robert Costanza
Visions, Values, Valuation And The Need For An Ecological Economics, Robert Costanza
Institute for Sustainable Solutions Publications and Presentations
Practical problem solving in complex, humandominated ecosystems requires the integration of three elements: (1) active and ongoing envisioning of both how the world works and how we would like the world to be, (2) systematic analysis appropriate to and consistent with the vision, and (3) implementation appropriate to the vision. Scientists generally focus on only the second of these steps, but integrating all three is essential to both good science and effective management. Subjective values enter in the vision element, both in terms of the formation of broad social goals and in the creation of a preanalytic vision,which necessarily precedes …

Recent understanding about system dynamics and predictability that has emerged from the study of complex systems is creating new tools for modeling interactions between anthropogenic and natural systems. A range of techniques has become available through advances in computer speed and accessibility and by implementing a broad, interdisciplinary systems view.
