Consider a particular type of resort: one which attracts nature-loving tourists, such as snorkellers and divers wishing to explore healthy coral reefs teeming with fish. If the fish disappear, so too will the tourists.
Let's explore the dynamics of such a system. First, we'll need to introduce a few systems concepts and tools.
Human development and activity leads to pollution, changes to ocean chemistry (ocean acidification) and physical modifications (changes to beaches, shores and rivers). [Ocean Literacy Principle 6d].
Everyone is responsible for caring for the ocean. The ocean sustains life on Earth and humans must live in ways that sustain the ocean. Individual and collective actions are needed to effectively manage ocean resources for all. [Ocean Literacy Principle 6g].
All systems have a function or purpose, though it is not always obvious. For example, the function of the digestive system is to break down food. The purpose of a football team is to win games. What is (or should be) the goal of a coastal tourism system?
The next diagram shows causal connections between parts of the system.
Follow the arrows in a Causal Loop Diagram to find circles - these are feedback loops. They govern the behaviour of the system.
How to read the Causal Loop Diagram below:
Attractiveness depends on BOTH Advertising & Environmental Quality
INCREASING Advertising INCREASES Attractiveness INCREASES Tourists
DECREASING Advertising DECREASES Attractiveness DECREASES Tourists
INCREASING Tourists DECREASES Environmental Quality
DECREASING Tourists INCREASES Environmental Quality
DECREASING Environmental Quality DECREASES Attractiveness DECREASES Tourists
Note: The term 'advertising' is used broadly here, to include the many forms of promotion, including magazine features and social media.
