| Zusammenfassung |
| Different land cover types are related to different levels of fire hazard
through their vegetation structure and fuel load composition. Therefore,
understanding the relationships between landscape changes and fire behavior
is of crucial importance for developing adequate fire fighting and
fire prevention strategies for a changing world. In the last decades the
abandonment of agricultural lands and pastoral activities has been the major
driver of landscape transformations in Mediterranean Europe. As agricultural
land abandonment typically promotes an increase in plant biomass (fuel
load), a number of authors argue that vegetation succession in abandoned
fields and pastures is expected to increase fire hazard. In this short
paper, based on 28 493 fires in Sardinia (Italy) in the period 2001–2010, we
show that there is no evidence of increased probability of fire ignition in
abandoned rural areas. To the contrary, in Sardinia the decreased human
impact associated with agricultural land abandonment leads to a statistically
significant decrease of fire ignition probability. |
