We're talking about spending 100 billion euros a year on assistance for adaptation and mitigation in the developing world. Though the prospects of that are unsure. Still, if it comes that far, there will be a lot of useless or even counterproductive ways to spend that money.
If it's spent with some consideration for the existing institutional framework in a social-ecological-system (which if you include agriculture, as I think you could, includes much of the relevant developing world) and the pressures that climate change will put on it, it becomes a lot more likely that it will be put to good use.
