Tragedy of Indigenous Whaling Game
Web Page for playing the precursor to the Tragedy of the Commons Game involving whales.
You are an elder of an indigenous people that have caught bowhead whales as part of their cultural heritage for centuries. You are very concerned that your heritage will die out if youth are not trained in the old ways of whaling. Many youth have already left for the life of the big city. You are also aware, however, that bowhead whale stocks are close to extinction. Although they are close to extinction because of past commercial whaling which, unfortunately, cannot be undone. You realize that the current threat to the bowhead stock comes only from the collective kill of bowheads by other indigenous groups like yours (no commercial whaling of bowheads is allowed and none is occurring).
You must choose each year how many boats to send out whaling.
- The number of whales killed - and hence youth trained - will depend on the size of the whale population: a larger population makes it easier to find a whale to kill, a smaller population makes it harder to find a whale to kill.
- Each boat kills a maximum of one whale per year.
- Each whale killed (NOT boats sent out!) trains 3 youth.
The total size of the bowhead population is influenced by:
- The current starting population.
- The annual 1% "recruitment" rate (12% birth rate minus 11% death rate) of the previous years population
- The number of whales killed by all indigenous peoples.
- The maximum carrying capacity of the ocean for bowhead whales (i.e., if no whales were killed, the natural mortality rate would balance the natural birth rate at a specific carrying capacity.
- The extinction point of one-tenth of the starting population, at which point so few whales are around that the population cannot recover.
Your goal in the game is to:
- Train as many youth as possible by killing whales,
- But, maintain a healthy whale stock by not killing too many whales,
- While recognizing that the sum of all bowheads taken by all indigenous peoples trying to train their youth may cause the bowhead population to crash.
Your decision about how many boats to deploy should reflect:
- The effort to train as many youths as possible. You will be given a direct measure of how many youths you have trained after each round/year.
- The effort to keep the whale population stable or growing so that you can train youths in the future. Unfortunately, accurate information about whale populations is hard to get, so you must estimate the whale population based on the "Whales Killed Per Boat" figure that you will be given after each round. As population increases, "Whales Killed Per Boat" will increase; as population decreases, "Whales Killed Per Boat" will decrease.

NB: This game doesn't really have a solution - I never quite got around to writing the script for it. But by playing a few rounds, this may give you a sense of the tradeoffs that indigenous cultures MAY face in retaining their indigenous culture while also trying to maintain a scarce environmental resource, like whales, on which their culture depends.There is a multi-person Tragedy of the Commons game that I have established to be played simultaneously by students in a class. If you are interested in finding out more, please read more about it on the main Tragedy of the Commons page.
