Land degradation versus fire: A spiral process?

摘要: Originally associated to arid regions, vulnerability land degradation (LD) has rapidly spread in temperate areas, such as the Mediterranean basin. In this region LD increased last years due worsening climate conditions, land-cover changes, soil erosion and anthropogenic pressures. Increasing is mutually linked with an increasing risk of disturbance propagation: spatio-temporal distribution areas different degrees determines dynamic patterns disturbance; turn, strongly affected by occurrence regime, which alters status quality a given territory. These considerations invite comparison between fire occurrence, since historically, represents one main sources, mostly human-induced strong seasonality pattern. Under certain may create conducive conditions for thrive that turn if repeated a...
