I'm looking for global maps of the production of several things from the late 19th century to the present.
One is important crops and agricultural productions. Grains, staple vegetables, fruits, sugar, coffee, chocolate, cotton, rubber, etc.
The other is deposits of minerals and other strategic resources. Iron, gold, aluminum, copper, rare metals, petroleum, nitrate.
I would especially like to have these as known reserves as of WWII. For crops, I would like to also have regions of the world suitable for their cultivation.
