"world food crisis"

I would like to know what exactly the world food crisis is. I know that a lot of the people in the world are suffering from starvation, but why? They don't have money? They should have a farm. Are they paying for the farm? Who? The government? They should have subsidies. Why? I just don't wholly understand how there can be a food crisis. Is it just Africa? Is it Asia as well? Unfortunately the news now just talks about it in general terms: No one's doing anything about the food crisis. We need money to fix the food crisis. Governments aren't doing anything for the food crisis. The food crisis is getting worse. We need more money to fix the food crisis.

How can a crisis be fixed if we can't definitively define what's going on???

Alright.
I think I've been able to define the food crisis. The main issue seams to be the rising food prices. Some are saying that the amount of grains and space that were originally used for food are now being used for alternative fuels is the cause of the lack of world food supply, but I doubt it. The alternative fuels push is only in higher developed countries that can afford to cut a few corn fields and replace them with rapeseeds or maize for ethanol. The issue is mostly located in Africa and they aren't sacrificing crops for alternative fuels and developed nations shouldn't (emphasis on the should not, this could even go back to the dumping issue) be the main source of food for poor nations.

The rising price issue has a few problems.
A) The prices started rising a few years ago even though everyone seems to want to blame 2008 as a single, separate problem.

B) I have yet to here any good reason for the increase in food prices in Africa. Africa shouldn't be doing too much trading in the agriculture filed because they should be worrying about their own people. In fact a number of organizations have already stated that they are going to invest in the education and development of agriculture production within Africa, not outside of it.

C) It's very difficult to trace who sells what food to who because no one wants to admit that they are importing it but everyone wants to be exporting. I know this from trying to research the agricultural dumping issue.

I'm going to start looking into the change in food prices and see what exactly happened and how it should be addressed.
