Although the supply chains through which foods are produced, processed, and transported can have a significant impact on carbon dioxide (CO2) emissions, consumers are largely unaware of how their food choices may impact the environment. Based on a previous related study, we hypothesized that a web-based training process could increase consumer knowledge and perhaps influence consumer behavior longitudinally. To test this, food distribution networks were modeled and analyzed to determine CO2 footprints for a variety of foods, and a training process was designed to teach consumers about the CO2 emissions for different types of foods that …

We build and analyze a dynamic ecological economic model that incorporates endogenous innovation on input substitutability. The use of the system dynamics method allows us to depart from conventional equilibrium thinking and conduct an out-of-equilibrium (adaptation) analysis. Simulation results show that while improvement in input substitutability will expand an economy, this change alone may not improve sustainability measured by indicators such as utility-per-capita and natural resource stock. It could, however, be possible that in combination with other technological progress, improvement in input substitutability will contribute to sustainable development. Sensitivity analysis also indicates a possible complication with the use of exogenous …

The supply chains through which foods are produced, processed, and transported can have a significant impact on the environment in terms of the carbon dioxide (CO2) that is emitted during each of these phases; however, little research has incorporated information about environmental impact into supply chain scenarios. Moreover, many consumers are unaware of how their food choices may impact the environment in this way. To fill these gaps, a tool called CarbonScope was developed to show consumers the CO2 emissions associated with different food types and food transportation scenarios. A short training was designed that walks participants through various food …
Systems Ideas And Sustainability, Martin Zwick
Systems Ideas And Sustainability, Martin Zwick
Systems Science Faculty Publications and Presentations
Slides from a presentation that provides an outline of ideas to understand how systems science and systems theory is related to, and can work for, sustainability. It illustrates how sustainability requires input from many disciplines, including graph theory, game theory, and thermodynamics, and is dependent on theories from ecology, sociology, and history.
A System Dynamics Model Of The Pacific Coast Rockfish Fishery, Wayne Wakeland, Olgay Cangur, Guillermo Rueda, Astrid Scholz

This paper presents a model of the dynamic behavior of the yellowtail rockfish of the Pacific Coast of the United States. The purpose of the model is to generate endogenously the historical data for fish population, fishing vessels, regulatory parameters, and fish harvest. The model was subjected to a variety of tests to determine its sensitivity to changes in key parameters and initial values, including extreme conditions. Model results indicate that acceptable biological catch and fleet capacity must be adjusted quickly in response to changing conditions, in order to improve fishery sustainability. Additional analysis reinforces the policy of setting the …
