Yes, there is an effort to study the total economic value of all the ecosystem services you get from a system. That will include the values you have enumerated. There's a lot of work currently ongoing. Before, we used to do fisheries alone and we'd do oil and gas alone. Now there is this push to do the whole thing.
My own partnership group has something called the OceanCanada Partnership, supported by SSHRC. It's a cross-country partnership of 20 private, academic, and government partners that are actually trying to do the same thing for the three ocean regions of Canada, trying to look at all the activities and calculate the economic value to the communities. That is ongoing from our side, but I know the other side is doing that.
It's very important to look at all of this. For example, we did a study that looked at fish value versus carbon sequestration value of the high seas. I'm going out of Canadian waters now. This is work I did together with Alex Rogers of Oxford. He did the science and I did the economics. What we found was that the carbon sequestration value is about 10 times the fish value of the high seas, for example. Those kinds of analyses are needed to help policy-makers like yourselves make sound economic decisions.
