National vulnerability to changes in nutrient supply due to foreign fishing and trade. (A) Map of vulnerability to changes in fisheries-derived nutrients. Vulnerability calculated from (B) exposure to changes in trade and foreign fishing plus (C) sensitivity to loss of fisheries-derived nutrients minus (D) adaptive capacity to changes in nutrient supplies. (E) Exposure, sensitivity, adaptive capacity, and vulnerability of SIDS. (F and G) Vulnerability of countries in relation to their 2015 trade and foreign fishing balance, showing countries with greatest gains and losses (highlighted in Fig. 1A) and SIDS (highlighted in Fig. 1E), respectively. Nutrient balance is measured in millions of RNIs and sums trade and foreign fishing balances (Fig. 1).
