 Countries' reliance on inland fisheries was estimated by catch  , per capita catch   percent reliance on fish for micronutrients, and percent 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. Projected concentrations  of vulnerable freshwater fishery species averaged within freshwater ecoregions under >2°C global warming and >4°C global warming estimated from recent past  to the end of the 21st century  . Numbers of vulnerable fish species translate to an average of 55-68% vulnerable at >2°C and 77-97% vulnerable at <4°C global warming. Darker shades indicate higher concentrations of vulnerable fish species. 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.
