Farmers in developing countries are in weak positions in many ways. They are vulnerable to the volatile market prices, which they can't have a controle of.
Giving the farmers "20% premium" to the market prices under the so-called "fair trade" concept may benefit them to a certain extent, but is that enough? is that enough to make them happy? is that enough to make them free from the volatile market prices determined not only by the supply-demand balance but also by speculative money?
No, I do not think so. I believe the only way, which is sustainable and reasonable in nature is, that the farmers themselves know the value of their products. Only then, they can gain a fair, yes, FAIR negotiation power as they know more about the products than any buyers. This would be the key to overcome the current problem happening in this distorted market economy.
