Understanding the environment: Flows and feedback

1.3 Activities

Activity 4A engages you in developing a more sophisticated visual model of one of the themes raised in the ‘Powerdown Show’ programme. The sign graph diagramming technique is the ultimate visual modelling approach for revealing positive and negative feedback relationships, so you will be using this technique to first explore, and then communicate, the dynamic nature of the complex situation you have chosen to investigate.

The first sign graph you will develop will focus on revealing positive feedback relationships – how a range of factors combine to create an increasingly problematic and unsustainable situation. Once you have developed this first sign graph, you will be asked to create a second sign graph by adding factors and relationships which will introduce negative feedback processes i.e. points of intervention to dampen down the escalating deleterious causes and effects identified in the first sign graph.
