 Countries  that have an overlap between high dependence on freshwater fish and high concentrations of fishery species that are vulnerable to climate change under two warming scenarios. Countries' dependence on inland fisheries for nutrition was estimated by catch  , per capita catch  , percentage reliance on fish for micronutrients, and percentage consumption per household . Z-scores of each metric were averaged for each country to create a composite index describing 'current dependence on freshwater fish' for each country with darker blue colours indicating higher dependence. Data on vulnerable fish species was from .
