A large part of me agrees with the author, although for somewhat different reasons, viz; that by providing handouts (as opposed to education and training) you only make people into dependants. That said, I don't think that there is much in the way of education that can be given by Europeans (from a temperate climate) to Africans who have survived for thousands of years on that continent, and developed good methods for dealing with the natural conditions there. The intervention we might be best advised to make is opposing the spread of social memes, such as religion, that encourage people to breed regardless of the resource available to support their progeny. (Christianity and Islam, basically). I think there is nothing wrong with excess food from one region being shipped to another region. I do think it should be traded/purchased, though, not donated. If the nations of Africa prove capable of repairing themselves, and building viable economies, then they will be able to obtain the resources needed to increase their populations by trading for them. This may seem ruthless, but at what point to you choose to recognise cyclical behaviour and disengage from it? I am not saying that there is no place for charity. In the wake of a natural disaster, aid can be offered, without compunction, but when a nations woes are self inflicted - eg; by letting the population grow out of control, or by agricultural practices that ruin the land, then the emphasis should be upon that nation to recover from that by its own means.
There is a whole other side to this argument, too, which is that it would be greatly to Africas benefit to disengage from Europe because of the terms of the unfair trade 'agreements' that European countries have dictated to African countries in return for 'aid'. If they refuse to play that game, then they wouldn't have to allow the import and sale of subsidised european products, eg, canned tomatoes, the availability of which put many local producers out of business (google for it). At the Gleneagles G8 summit, Gordon Brown, Bob Geldof and others boasted of having written of large amounts of Africas debt. In fact, the amount written of was trivial, and it was tied into the sort of ttrade agreements that I have mentioned.
There is an excellent book on this topic called 'The Lords of Poverty' by Graham Hancock. He details the nature of the governement aid agencies (as opposed to the voluntary aid agencies) and their practices, as well as the fact that much of the food aid sent is often goods that were considered unfit for consumption in the donor country.
Apologies for length.
