The nations of Africa need to redeclare their independence, and wean themselves from aid altogether. Not "cold turkey", but fairly quickly. You must reorient your production to serve your domestic markets first. Excessive orientation to the export market hinders your production for local needs, and ties you to the import market in part by giving you money that can only be spent there. Imports then suppress local production of their competition, and further your nations' dependence. Accumulated foreign money that cannot really be incorporated into the economy corrupts officials continent-wide: what you can readily buy with it is private jets and limousines. Most of what you are exporting your descendants will need.

A suggestion for the use of a portion of that foreign money. Invest in hardware to determine the concentration of pollutants in tissue samples. Use it to determine what part of Africa's colossal Typha infestation is fit for human consumption. This ubiquitous nuisance can be a huge food crop, but it has the habit of collecting and hoarding toxic chemicals. There is enough going to waste in the Lake Chad basin to feed every African a daily loaf of bread. Uncontrolled, it causes incredible troubles. What isn't fit for human consumption is fuel grade biomass. The hardware is hi-tech and pricey, but not compared to a day's food imports.

Africa has enormous resources, and a large, work-hungry labor force to develop it with.
