An interesting (and infuriating) post on The Angry Black Woman about land grabs. Executive summary: 'investors', initially officials from richer countries apparently concerned about food security, latterly all sorts of other people just interested in the financial value, have been buying up land in the developing world, especially in Africa.
There's lots of useful resources and links from that post, but it doesn't really take a genius to recognise that this is unlikely to end well for the people living in those countries. It's the same as the biofuels issue: the rich buy up the land at the expense of those who live off it.
Even if you think that local people where the land is being bought are actually getting the money (which is, frankly, pretty monumentally unlikely), the economics of the situation (on an assumption of food scarcity, which is after all why the 'investment' is considered valuable) means that it's a bad deal. The money can't make up for the loss of the food -- because the cost of the food is going to be greater than the cost of the land (otherwise no money is made). Not only that, but the food is going to go first to richer countries who can afford to pay more.
Yet another way in which climate change and capitalism are screwing the poor of the world over first. Unfortunately it looks like it's going to be business as usual in Copenhagen; continuing to put financial interests over global wellbeing. If you're in the UK, the Wave march is this Saturday; after that there's the more radically-inclined Climate Camp COP OUT CAMP OUT event. Come along to push the idea that Copenhagen needs to produce radical results.
