Question

Have ecological disasters in Africa been due to drought or Western-style political and economic institutions?

Answer 1

Some have been due to floods --haven't you heard?

Answer 2

The leading ecological disaster in Africa is desertification (the southern encroachment of the Sahara desert).  

The political agenda of Marxist regimes either "collectivizes" farms, or transfers land away from productive farmers into the hands of political allies resulting in dramatic decreases in farm output.  Though this isn't specifically an ecological disaster, it is certainly a human one.

Due to the insecure property rights in African Islamic nations, nobody in those countries has any incentive to make improvements to the land because the best lands are the first to be confiscated "to the cause of allah".  This is the primary contributor to desertification (the southern encroachment of the Sahara desert).

Go look at a map.  Every country in Africa that falls to Islam becomes a desert within a single generation.

Another human tragedy is the do-gooder non-profits that think they're doing good by shipping food from "have" nations into "have-not" African nations to ebb the hunger caused by Marxist and Islamic regimes.  This "free food" competes with private African farmers (who don't get government subsidies like they do in America) and puts them out of business.  This cycle actually worsens the problem they were trying to fix.

In short, there are no ecological disasters in Africa due to Western style political and economic institutions as Marxism and Islam are both Eastern European and Middle-Eastern in derivation.
