The vulnerability of Mediterranean arid and semiarid lands to human-induced changes in soil use means that the effects of climate change upon these environments will be exacerbated (Scharpen seel & Pfeiffer, 1998). Reduced precipitation or increased temperature accelerates l and degradation through the loss of plant cover, biomass turn over, nutrient cycling and soil organic carbon storage, accompanied by higher greenhouse emisions (Ojima et al.,1995). Moreover, if the projected increase in temperature following global climte change occurs, the degradative processes Will be aggravated (Kimble et al., 1998). Long term data series from natural rainfall events in semiarid environmnts are crucial for studying nutrient dynamics because: i) the soil's response within a few months of vegetation removal may not be sufficient for estimating its long-term behavior; and i i) it is difficult to produce data comparable to natural storms using rainfall simulators (Flanagan & Foster ,1989).
