Gabon was also a temporary member of the United Nations Security Council for the 2010 -- 2011 term .   Abundant petroleum and foreign private investment have helped make Gabon one of the most prosperous countries in Sub-Saharan Africa , with the 4th highest HDI and the third highest GDP per capita -LRB- PPP -RRB- -LRB- after Equatorial Guinea and Botswana -RRB- in the region . GDP grew by more than 6 % per year from 2010 to 2012 . However , because of inequality in income distribution , a significant proportion of the population remains poor .
