Truffle farming and global climate change


Black truffle is a long-term culture where the infected truffle trees we are planting now will be in peak production in 15-30 years. It is therefore interesting to look how climate will change in that period of time.
In the picture you can see how in Spain, with a 80% chance there will be a sharp decline in rainfall in 2030.
This can lead to be more interesting to increasingly plant at higher altitude or northern orientations, as occurs in warmer southern areas of Spain, like Andalusia, where the natural truffle require more shade and less direct sunshine.
These researches are not new and from the Forest Technology Center of Catalonia, a map for growing the black truffle in Catalonia was published in 2007, which included a drastic reduction of the surface susceptible to be planted in 2040, just as shown in the pictures below, the first map for 2007 and the second for 2040 (in green the potential area for growing black truffles):
