Okay, this may seem a bit rambly, but who knows.

It seems that we are heading towards a global spanning trend of food shortage. Some history, perhaps.

In the 80's, A small country called Haiti was having some slight issues after their Ex. Dictator decided to slip off with basically all of the nations economy. Oups. At this time, their country was self-sufficient in the basic food needs.

What happened? They needed a loan to get the economy up, but to get this, the US and other countries via the IMF (International Money Fund) needed to get something out of it, in this case, a chance to export goods to the country.  For US, this meant sniping the local food producers via subsided rice and goods, ending up with an imploding local market that isn't competitive due to the scale of the American rice producers.  Local market falters.

So, this has caused what was once a local market to be dependant on importing basic goods.  Buisness as usual.  Until the US hits a snag in their economy, and gets into bouts with all the large oil-producers, so they have to change to growing ethanol-producing crops internally, rather than grow export goods.

This means, the prices of the export goods are no longer subsidized, and Haiti cannot afford the rice anymore.  However, since the internal rice market has already collapsed, they now have a problem again. No food at all.

Well, that's just Haiti. Small island, crap economy. Of course it happens, some people will starve and we can go bail them out and fix stuff again.

Except that it isn't only there.  Other major grain exporters are starting to wisen up, and cutting down on the exports.  USA, has moved towards making corn for Ethanol fabrics, and are at the point where they consider food rations.   Australia are cutting down on their exports and Kazakhstan imposed an export ban on grains.

But, only the poor suffer so far, isn't it? It seems not. Japan, one of the world's powerhouses when it comes to technology, a huge population on a small area, is now in trouble for real, it seems that you cannot buy butter in Japan anymore, and that flour and grains are becoming increasingly expensive.

So. What can be done about it?  Well, for starters. Let's stop this escapism that is Ethanol produced from grains and corn. It's not a viable thing to replace our horrendous oil dependency with one that forces that kind of produce loss.  It can be a stop-gap means and it's a good technique, but we are causing even more trouble by going this way.

Second,  We need to become more self-sufficient. Some nations do not have a choice, (Hello Japan) but others do, Sweden are doing good at this point, since there isn't that huge a population for the area of produce, still, more has to be done globally. Economically it may be "better" to sell to foreign markets that pay more than local ones, but lets face it, doing so takes a toll on nature in the form of emissions from transport, as well as binding the food produce to oil consumption.

The other thing is to actively step in and try to assist countries in becoming self-sufficient. We must stop making countries like Haiti dependent on us on purpose, and let them remain capable of sustaining themselves.

Edit: Update.

If you consider the USA as a driven corporation, it makes economical sense for them to ruthlessly snipe the internal economy and sustainability of Haiti with low-cost subsidised rice, and then when Haiti has no choice, raise the prices and bleed it dry. Afterwards it is cheap and easy to purchase the remains, patch up the economy and take over.   Though, it may be even cheaper to just ignore the starvation and leave them alone to suffer miserably.
