The War on Salmon! Smoke dope, eat almonds, kill fish.

Two articles I read this morning have the same thing in common---the plight of salmon in California due to a severe water shortage.  Nice examples of scarcity of a resource (water) and how opportunity costs arise in allocating that resource (for salmon? almonds? marijuana?).

Each article cites a different culprit for the suffering salmon (emphasis mine):

Cannabis farming in California using so much water it could wipe out salmon population, biologists warn

"Water use and other actions by the marijuana industry in the Emerald Triangle of Northern California and Southern Oregon are threatening salmon already in danger of extinction, US biologists have said."
California Drought Has Wild Salmon Competing With Almonds For Water
"The ongoing California drought has pitted wild salmon against farmers in a fight for water. While growers of almonds, one of the state's biggest and most lucrative crops, enjoy booming production and skyrocketing sales to China, the fish, it seems, might be left high and dry this summer—and maybe even dead."
Use marijuana, quench the munchies with almonds, kill salmon.

Save the salmon, but don't smoke dope and/or eat almonds.

Change the order, but the lesson remains the same:  Choices, choices...

  1. We need an optimization! What model would suit to best find pot* almond* and salmon* to best maximize benefit to society?

    1. Normally economists would suggest proper pricing of water to ration it to its highest value usage but since marihuana is illicit and river/stream water for salmon is "free" it would only punish almond growers and other ag interests. Not sure what the alternative is. Thanks for the comment. I appreciate it.

    2. But prices work perfectly for imposing limits to externalities like salmon; that's what pigouvian taxes are, prices for goods that create externalities. And marijuana may be illegal, but the water used is probably not stolen, so the prices would fix that problem as well.

    3. David,
      Agreed. However, the economic solution of pricing water properly collides with the politics of water. Ag interests and the desire to provide a cheap utility to people are powerful tonic to politicians/policymakers to keep it cheap/subsidized. Then they resort to short-sighted conservation measures that do no good at all. Part of the water shortage is a political problem as well as an environmental one. Thanks!

  2. Nice link and certainly helpful. The two stories I linked to are for mass consumption and not a detailed analysis. Thanks for posting it.
