It's old news that the Allies had access to far more natural resources than the Axis did. The chronic German shortage of oil is well known, for example. If we widen the horizon to include other minerals, the German (and to a lesser extent Japanese) shortage of strategic minerals is exacerbated which the tables below hopefully illustrate. For example it has been stated that German armour quality began dropping during the war due to Germany's stocks of molybdenum running out.
What is perhaps less known is the large proportion of strategic minerals which came from Africa. More than 90% of the world's industrial diamonds came from Africa, for example. Most of the uranium for the Manhattan Project came from the Belgian Congo. The mining of Africa's minerals was stepped up due to the increasing demands of war, sometimes ruthlessly, with forced labour conscription etc. It can be read from the tables, below, that the mining of Africa's resources was at its max during the war, which is why Africa's share of mineral production expressed as percentages tapers off again after the war in the 1950 columns.
