ALT Imports of food commodities from major export regions to PICTs and trade flows between PICTS (in gold). Shown are mean annual trade flows for the period 2014–2018 pooled for all food commodities included in this study (see Table S1 for exclusions). Trade flows to and from Papua New Guinea not shown. Red dots indicate relative geographic position of PICT capitals. Residual trade flow into the region includes imports from Africa, the Middle East, South America and South Asia and flows that sum to less than 100 t. Also shown is a residual PICT-PICT trade flow which is the sum of all trade flows <50 t p.a. for each PICT-PICT pairing. The width of lines and height of columns are proportional to quantities traded. Lines representing flows of less than ca. 100 t are not visually distinguishable.
