Whereas agriculture suffer the tourism pressure on farm lands, tourism is also an important market for local agro-food products. However, these local products, recognized and labelled for their special quality (through GI's) are sold to high prices. Which raises the question of access to "identity" products for the local people. In fact, Corsica faces a kind of double gentrification process : urban gentrification on one hand, and gentrification related to the consumption of local agro-food products on the other hand.
