Climate change is one of the most significant challenges facing humankind in the 21st century. Current scientific understanding suggests that the food system has the potential to contribute significantly to forces driving climate change and is likely to be affected in important ways by it.
The causal loop diagram below offers a way to visualize the food system\u2019s impact on climate change and the impact of climate change on the food system.
The positive ( ) signs show how one factor leads to an increase on the factor that the arrow points to. For example, rising population and income levels are key external drivers in this system. Both lead to increased demand for food and for energy. The negative (\u2013) signs show how an increase in one factor causes a decrease in the other. For example, increased food production leads to lower food prices. <\/p>\n

Choose one of the arrows and explain how the factors are related, causing the sign that is shown on the diagram.
Three feedback loops within the system (marked 1, 2 and 3) are identified with counter clockwise arrows, but they are not \u201csigned\u201d as being reinforcing ( ) or balancing (-). Assign a sign to each loop and explain your reasoning for doing so. (Note that some loops are embedded in other loops.)
There are almost certainly some missing arrows in this diagram that would create new feedback loops. Identify an important missing arrow (connecting which points, or other factors not given) and \u201csign\u201d its impact ( \/-). Briefly explain why it is important. <\/p>\n","protected":false},"excerpt":{"rendered":"
