Percent change in production and consumption sustainability for the top 25 seafood producing countries (according to FAO data).

Production sustainability is the FMIP for each country, and mean consumption sustainability is the mean of the three FMIC derivations. We calculated the percent change between these values for each country by subtracting the mean consumption sustainability from the production sustainability and dividing by the production sustainability and multiplying by 100 ((FMIP−mean(FMIC)/FMIP)*100). The nature of this equation means that positive percent change values occur for countries that have a decrease in consumption sustainability compared to production sustainability and negative values occur for countries that have an increase.
