1

Provisioning services

Things we consume or utilize. Ex) Water, crops, lumber

2

cultural services

Things that inspire, teach or entertain. Ex) Birdwatching, fishing, stargazing

Seed dispersal, nutrient cycling, primary production

5

Stocks

the accumulation or storages of things. Have a flow in and flow out, which has rate in and rate out.

6

system archetypes/behaviors

similar patterns of behavior. Ex) tragedy of commons & limits to growth

7

flow

movement if things in and out of stocks

8

rate

speed at which things flow in and out of stocks

9

residence time

time something spends in any particular stock

10

Feedback

close the route between stock, rate and flow which creates dynamic behavior of that stock.

11

Types of feedback loops

(R)einforcing: accelerate the size of the stock; positive
(B)alancing: stabilize systems and drive that system to a certain “stable” state or target; negative

12

limits to growth

something inside or outside the system limits the growth of the condition. Will be S-shaped if the limiting condition is something constant such as available habitat, reached carrying capacity. could be 'overshoot +crash' b/c disease/resources/war etc.

13

tragedy of the commons

another common (grazing land), the tragedy (overgrazing) and the reasoning for human behavior that incentivized over exploitation of a commonly held resource. solution is regulating.
