6) are in parentheses. DES stands for dietary energy supply (kcal/cap/d), GDP for gross domestic product (current US$/cap) and DEP for dietary energy production (kcal/cap/d). Units of freshwater availability, net food exports and arable land are m3/cap/yr, kcal/cap/d and m2/cap, respectively. Share of global population in 2005 in countries with significant positive and negative correlations. Absolute population numbers (x10
