Ocean Accounts Explainer Video | Fisheries Resource Center of Indonesia 

Amazing

Keren banget

Nice video. One sentence needs clarification, though: "by knowing the values of marine resources we can manage them better". This surely applies to physical values, but it does not to the monetary value. The latter encompasses, as shown in the picture where economic valuation is at the centre, also regulating and supporting services, which are (like also some cultural ones) not (and shall never be) marketed. Accountants in these cases use hypothetical market prices, i.e. the prices they think would prevail if transferrable property rights were imposed on the services. But what's the use and meaning of this, besides signalling that there is a potential for some to make money (at the mere expense of others, since rents are not production) if these potential markets are established in reality? All we need to know for sustainable management is how much can be taken, and how, and how much the ocean can be used otherwise, for the biofisical cycles not to be compromised. Why is policy so interested in economic valuation instead? (Ps. of course it is useful to know, e.g. how much income is actually derived from the use of the ocean and its resources, but that's a different story)
