In this lecture, we discuss topics from Chapter 9 of Morecroft (2015). These topics discuss how to use system dynamics modeling in setting policies for urban growth and renewable resource management. We explore a basic model of the growth (and limits to growth) of a city before we then switch to our progressively growing model of a fishery. This fishery exhibits a "tipping point", which gives us an opportunity to discuss tipping points and bifurcation diagrams (for simulation) We then close with a discussion about how to "close the loop" in the fishery model and use modeled human behavioral responses to changes in fish density. This discussion lets us introduce policy lever as well and explore how well they might accomplish our sustainability goals.
