This case study presents a framework for evaluating the sustainability of indirect potable reuse (IPR) and direct potable reuse (DPR) in Las Vegas, Nevada. A system dynamics model was developed to simulate population growth, water supply, water quality, energy costs, net present worth (NPW), and greenhouse gas (GHG) emissions. The model confirmed t...
Conference Paper
This paper explores the concept of system dynamics insights. In our field, the term “insight” is generally understood to mean dynamic insight, that is, a deep understanding about the relationship between structure and behavior. We argue this is only one aspect of the range of insights possible from system dynamics activities, and describe a broader...
Article
A recurring topic in the annual System Dynamics Society Presidential Address is the need to promote high-quality system dynamics practice in a way that ensures sustainability and growth of the field. Formal training programs and interaction with colleagues at annual conferences play a critical role in accomplishing these goals but are limited. Most...
Article
Understanding vulnerabilities in complex and interdependent modern food systems requires a whole-system perspective. This paper demonstrates how one systems approach, system dynamics, can help conceptualize the mechanisms and pathways by which food systems can be affected by disturbances. We describe the process of creating stock-and-flow maps and...
Article
Background. Poor public understanding of accumulation principles obstructs public engagement in environmental decision-making. Simulation-based learning environments (SBLEs) show promise for improving understanding. Purpose. This study tested the hypothesis that use of stand-alone, self-contained, online SBLEs can improve user understanding of and...
Conference Paper
Full-text available
This paper presents the first step in applying a system dynamics analysis to the question of food system vulnerability and resilience in developed countries. Existing literature and models about food security largely focus either on effects of climate change on agriculture at a global scale or on specific issues on a regional scale, most often in f...
Article

This paper describes the results of a paired experiment testing the effect of system dynamics simulations on systems understanding in undergraduate environmental science courses. The performance of 298 students in four sections was measured at several points during the semester. Half the students used system dynamics simulations in their assignment...
Conference Paper
Full-text available
Most of the system dynamics studies that evaluate d ecision making in complex dynamic task focus on the evaluation of performance over repeate d trials and on the effectiveness of different instructional strategies as far as performance is c oncerned. Especially when a strategy seems to yield promising results in terms of performance, it becomes es...
Article
Full-text available
This paper reports on an experimental study testing the relative effect of using simulation models on systems thinking in a college-level Introduction to Environmental Science section. The preliminary findings show mixed results. It is unclear whether this is a result on the systems simulations used in the interventions or the assessment techniques...
Article
Full-text available
There is concern that elevated levels of selenium found in the source water of a newly formed wetland park in Las Vegas, Nevada, may have detrimental effects on local wildlife. In this study, we collected and analyzed water samples monthly for a three year period from the inflow and outflow of the system. We also gathered dominant aquatic plants an...
Article
Full-text available
This paper proposes a taxonomy of systems thinking for use in developing and measuring the effect of systems thinking educational efforts. The taxonomy was derived from a review of the system dynamics literature and interviews with systems educators. Although there is no single definition of systems thinking in the system dynamics community, there...
Article
Full-text available
This paper uses the framework proposed by Rouwette et al. (2002) to describe the group model building stage of a project to integrate land use, transportation and air quality planning in a rapidly growing metropolitan area. The paper has two purposes: compare this case with the findings of Rouwette et al. (2002), and test the framework for reportin...
Article
Full-text available
This paper discusses a model developed to assess the effects of land-use changes on traffic congestion and air quality. The inputs are characteristics of development and the outputs are time in traffic per capita, and tons of carbon monoxide from vehicles. As previously developed urban dynamics models have done, the model includes a relationship be...
Article
Water managers increasingly are faced with the challenge of building public or stakeholder support for resource management strategies. Building support requires raising stakeholder awareness of resource problems and understanding about the consequences of different policy options. One approach that can help managers communicate with stakeholders is...
Article
Dana Meadows believed that computer simulation models and systems thinking could be powerful tools for democracy, helping make social decisions and the assumptions on which they are based more transparent and open to public debate. She also believed that people should be more involved in making conscious and informed choices about their future. In...
Article
This paper examines the co-evolution of the Las Vegas, Nevada metropolitan area, Las Vegas Wash ecosystem-a downstream riparian wetland-and Wash management as a case of urban-environment dynamics. Since Las Vegas Wash provides the primary drainage for Las Vegas, changes in the urban system lead to changes in the Wash and its ecosystem. The populati...
