Once again the 'legacy' of centuries of European colonization models for which the IMF and World Bank were developed, as in South and Central America, "externalized" in the terms of finance, are the historical roots in tandem with desertification.

No, the weapons manufacturers are seeing too rich a hey-day.
Since the 60s, major dam construction ostensibly for "irrigation", implicitly alluded to in the article, now see mining vultures and 'Displaced Persons Camps' in continuing Africom agendas.

They are power juggernauts with predictable militarization coat tails for globalization of 'citizens united' written into the process. Follow the money, follow the water.
