According to recent projections about future climate conditions, a general decrease in annual precipitation and an increase in the risk of summer drought is likely to occur in southern Europe and across most of the Mediterranean Basin. These conditions will exacerbate wildland fires, which already represent an important disturbance in Mediterranean ecosystems. Evergreen sclerophyll shrubland, indeed, represents a relevant component of both the Mediterranean vegetation community and understory vegetation, and often constitutes the surface fuels primarily responsible for the ignition and spread of wildland fires in Mediterranean areas. The water content of live fuel plays a critical role in determining fire occurrence and spread, especially in Mediterranean shrubland, where live fuel is often a large fraction of the available fuel which perpetuates the fire. A more severe and/or prolonged drought season could therefore influence the water fuel status and the length of the fire season, and, consequently, cause a general increase in fire danger conditions in the Mediterranean area.
