From: Vulnerability of blue foods to human-induced environmental change

a,b, Heat map (a) and radar plot (b) of standardized impact scores of the four clusters obtained by k-means analysis. The four clusters are characterized by high impact (n = 33 countries), medium-high impact (n = 91 countries), medium-low impact (n = 39 countries) and low impact (n = 59 countries). The list of countries of the four clusters is provided in Supplementary Data 3.
